3 Section I
General background
0.1. The dispute which the Argentine Republic (hereinafter “Argentina”) submitted to the
International Court of Justice on 4 May 2006 is em bittering to a concerning extent the traditionally
fraternal and exemplary relations between Ar gentina and the Eastern Republic of Uruguay
(hereinafter “Uruguay”).
0.2. Argentina and Uruguay are two countries deep ly united by historical, social and cultural
links that go beyond mere neighbourly relations between States. The Treaty on the River Uruguay
of 1961 describes these eloquently, its preamble referring to “the close and immutable bonds of
1
affection and friendship which have always existed between their respective peoples” .
0.3. The successive announcements, in the space of 16months, of the construction of two
enormous pulp mills on the left bank of the River Uruguay, near the town of Fray Bentos in the
Uruguayan Department of RíoNegro 2, marked a sudden and serious deterioration in these
relations. Several factors reflect the scale of the situation:
⎯ firstly, the unilateral decisions of the Uruguayan Government to authorize the construction of
the two mills were taken in breach of the clear requirements of the Statute of the River
Uruguay. That treaty, which was signed by the two States at Salto (Uruguay) on
26February 1975 and entered into force on 18September 1975 (hereinafter “the
3
1975 Statute” ), establishes close co-operation between the two riparian States which had
4 previously been entirely satisfactory, a key el ement being the procedure for prior notification
and consultation laid down by Articles 7 to 13 ; 4
⎯ secondly, the anticipated impact on the environment and the quality of the river waters is
bound to be substantial, as pulp mills are among th e most polluting types of industrial plant;
the city of Gualeguaychú and its region, situ ated on the Argentine bank of the river, opposite
the site chosen for the mills, are centres for ag riculture and, in particular, ecological tourism,
which is developing rapidly there; and
⎯ thirdly, the population of the Argentine province of EntreRíos in general and of the city of
Gualeguaychú in particular has a long community tradition of protecting the environment.

0.4. Indeed, for some years the province of En tre Ríos has been deeply concerned to respect
the environment. The city of Gualeguaychú leads the way in developing this ecological
awareness . 5
0.5. The sudden announcement, on 21September 2006, by the management of the Spanish
company ENCE, which had obtained authorization from the Uruguayan authorities to construct one
of the two mills at issue near Fray Bentos, that it was abandoning the project 6, does not affect the
substance of the dispute. Firstly, there is no question of the abandonment or relocation of the other
mill, whose construction by the Finnish company Botnia is proceeding apace and whose production
capacity will be twice that initially planned by EN CE for its own mill. Secondly, while ENCE has
abandoned the siting of the latter i7 the immediate vicinity of the Botnia mill, it has announced that
5 it intends to build it elsewhere , at a location yet to be confirmed when this Memorial went to
press .
0.6. Because of the uncertainty in this respect, this Memorial has been drawn up on the basis
of the situation existing on the date it was comple ted. Evidently, if the situation regarding the
ENCE project were to change, Argentina reserves the right to adapt its conclusions and supporting
arguments accordingly . 9
Section II
Procedure
0.7. Against this background, Argentina filed w ith the Registry of the International Court of
Justice on 4May 2006 an Application institutin g proceedings against Uruguay, in which it
requested the Court to find that the authoriza tion, construction and future commissioning of two
pulp mills on the left bank of the River Uruguay ar e in breach of the respondent State’s obligations
under the 1975 Statute and the other rules of internati onal law referred to by that Statute, and that
these breaches engage the international responsibility of Uruguay with all ensuing legal effects.
0.8. At the same time, Argentina filed a re quest for the indication of provisional measures
pursuant to Article 41 of the Statute of the Court and Article 73 of the Rules of Court, based on the
significant and irreversible damage that the comm issioning of the mills will cause to the quality of
For example, its waste treatment system is the onlone of its kind along the River Uruguay and in the areas
affected by it. See Chap. VI, paras. 6.51 and 6.52.

Vol. VI, Ann. 6).
At their press conference of 21Sept. 2006, the manageme nt of ENCE did not answer journalists’ questions on
this subject (Anns., Vol. VI, Ann.1). Regarding the announcement ma de on 12Dec.2006 by the Chairman of ENCE
that the CMB project was to be relocate d and sited close to the Uruguayan town of Punta Pereira on the Río de la Plata,
see Chap. VIII, paras. 8.6 and 8.7.
See Conclusions, para. 9.2. - 3 -
the waters of the River Uruguay and the serious ecological, social and economic effects that the
6
construction of the plants are causing and will cause in the areas affected by the river, including its
right bank.
0.9. By its Order of 13July 2006, the Court found that “the circumstances, as they now
present themselves . . ., are not such as to require the exercise of its power under Article 41 of the
10
Statute to indicate provisional measures” . However, the Court stated that “in proceeding with the
authorization and construction of the mills, Ur uguay necessarily bears all risks relating to any
finding on the merits that the Court might later make” 11. It also pointed out that “the Parties are
required to fulfil their obligations under international law”, stressed “the necessity for Argentina
and Uruguay to implement in good faith the cons ultation and co-operation procedures provided for
by the 1975Statute, with CARU [Administrative Commission of the River Uruguay; see
Chapters II and III] constituting the envisaged forum in this regard” and further encouraged “both
Parties to refrain from any actions which might re nder more difficult the resolution of the present
dispute” .2
0.10. By a second Order made on the same date, the Court fixed the time-limit for the filing
of the Memorial of Argentina as 15 January 2007 and that for the filing of the Counter-Memorial of
Uruguay as 20 July 2007. This welcome brevity s hows that the Court has recognized the need to
settle the dispute referred to it by Argentina in the shortest period compatible with the detailed
presentation of their respective arguments by the Parties. This Memorial has been filed in
accordance with that decision.
Section III
7
Scope of the dispute
0.11. In its Order of 13July 2006 on Argentina’s request for the indication of provisional
measures, the Court held that:
“the present case highlights the importance of the need to ensure environmental
protection of shared natural resources while allowing for sustainable economic
development; whereas it is in particular n ecessary to bear in mind the reliance of the
Parties on the quality of the water of the RiverUruguay for their livelihood and
economic development; whereas from this point of view account must be taken of the
need to safeguard the continued conservati on of the river environment and the rights
of economic development of the riparian States” 13.
0.12. This wording defines concisely and exactly an important aspect of the scope of the
present dispute, relating to the threat posed to the environment of the River Uruguay and to the
sustainable economic and social development of the Argentine province of EntreRíos by the
10

14
definite construction of one enormous pulp mill at a particularly sensitive site and the likely
construction of another mill elsewhere on the section of the river common to the Parties . 15
0.13. Moreover, the Court is effectively bei ng asked to “rescue” the 1975Statute: through
its total and continuous disregard for the procedures laid down by Chapter II of that instrument and
its refusal to carry out, in prior consultation with Argentina, i.e. before the granting of authorization
for the planned mills, a full and precise assessme nt of the effects of their construction and
commissioning, Uruguay has in fact dealt a blow to this treaty, strict observance of which will
ensure “the optimum and rational utilization of the River Uruguay” 16 and, beyond that, harmonious
relations between the Parties.
17
8 0.14. As Argentina explained in its Application , the dispute arose following the unilateral
authorization issued by the Government of Uruguay on 9October 2003 to the Spanish company
ENCE to construct a very large pulp mill on the left bank of the River Uruguay, some 30 km from
the Argentine city of Gualeguaychú (the largest conurbation on the section of the RiverUruguay
common to the Parties, with nearly 100,000inha bitants) and 12km from the Argentine resort of
Ňandubaysal. One of the main revenue sources of this part of the Argentine province of Entre Ríos
18
is ecological tourism .
0.15. This project, entitled “Celulosade M’ Bopicuá” (hereinafter “CMB”), was swiftly
followed by another, on an even larger scale, since on 14February 2005, the Government of
Uruguay authorized the Finnish company OyMet sä-BotniaAB (hereinafter “Botnia”), also
unilaterally and in breach of the 1975 Statute, to construct another mill (“Orion”), with an even
greater production capacity, just 7km from CMB 19. The location of the two mills is shown in
Figures 1 and 2.
1On the characteristics of this mill, see para. 016 and Chap. VII, Sec. III.
1See para. 0.6.
16
Art. 1 of the 1975 Statute.
17
See paras. 5-23 of the Application.
1See Chap. VII and Ann. M to the Lati noconsult report (“Assessment of the fluvial environment of the proposed
Botnia pulp mill on Río Uruguay”) at http://www.ecopaedia.com.ar/publico/ea_report/ (username: ea_annex; password:
ea_annex).
1In addition, on 5 July 2005, Uruguay authorized Botnia to construct a port connected to the mill planned by the
company (Anns., Vol.VII, Ann.15). This port was unilate rally authorized to operate on 24Aug.2006 (see para.0.23).
Furthermore, a third major pulp mill project is planned on be half of the Swedish-Finnish transnational company Stora
Enso. This mill, also with a production capacity of 1 milli on tonnes, is due to be sited on the Río Negro (see Ann. XXV
to the Application and Anns., Vol. VI, Ann. 7). - 5 -

Fig. 2 - 6 -
0.16. When fully on stream, it was anticipated that the two mills, construction of which
should be completed in August2007 for Orion and July 2008 for CMB 20, would initially produce
21
1million tonnes and 500,000 tonnes of pulp respectively , with CMB’s output subsequently also
being increased to 1million tonnes 22. In terms of their production capacity, these mills are
23
currently among the largest in the world .
0.17. The announcement by the management of ENCE, in September2006, when the
drafting of this Memorial was already at an a dvanced stage, that it was provisionally abandoning
24
the construction of the CMB mill ⎯ at least at the planned site ⎯ has no major bearing on the
scope of this dispute. This is because:
⎯ the procedure followed by Uruguay in authorizing the construction of the CMB mill was a
gross breach of the letter and the spirit of the 1975 Statute and is in the nature of a threat to that
25
treaty, the safeguarding of which is one of the principal issues in these proceedings ; the
announced abandonment of the project does not re move those irregularities, which constitute a
dangerous precedent; and
⎯ the adverse effects of the Orion mill clearly re main and are far from negligible, even when
26
viewed in isolation .
27
11 0.18. By its nature, the pulp industry is highly polluting and the siting of the Orion mill on
the River Uruguay is sure to cause damage to its environment and the areas affected by it, including
the health and well-being of the communities living on both sides of this shared natural resource.
As emphasized by Mr. Enrique Viana, Uruguayan National Prosecutor,
20
CR 2006/47, 8 June 2006, p.46, para.15 (M r.Reichler). See also the affi davit by MsAlicia Torres, National
Director for the Environment, Observations of Uruguay, Ex hibit1, pp.10-11, the affidavit by Mr.PoncedeLéon, ibid.,

21Ann. I to the request for indication of provisional measures.
22
The management of ENCE have indicated that, when it is built on a new site, their pulp mill will also have a
capacity of 1 million tonnes (Anns., Vol. VI, Ann. 1).
23
Anns., Vol. V, Ann. 2.
24
See para. 0.5.
25
See para. 0.13.
26See Chap. VIII, para. 8.7. Moreover, ENCE has in no wa y abandoned its plans to build a mill of the same type
elsewhere in Uruguay, although the exac t site for the relocation had not been confirmed when this Memorial was
completed.
27According to Delores Broten and Jay Ritchlin: “Pulp a nd paper is the third largest industrial polluter to air,
water, and land in both Canada and the United States, and re leases well over a hundred million kg of toxic pollution each
year” (National Pollutant Release Inventory, 1996). More specifically on the impact of the paper industry on water, they
point out: “Pulp mills are voracious water users. Their consumption of fresh water can seriously harm habitat near mills,
reduce water levels necessary for fish, and alter water temperature, a critical environmental factor for fish”
(Deloresroten and Jay Ritchlin, “The Pulp Pollution Primer”, http://www.rfu.org/PulpPrimer.htm).
Professor Wayne Gray also indicates, as regards atmospheric pollution, that:
“As part of the manufacturing process, pulp and paper mills generate sulfur dioxide and
particulate matter-dust, soot, and as hes... from the burning of fossil fuels like coal and oil for energy.
Both pollutants can cause respiratory problems, damage to property, and reduced atmospheric visibility.
Sulfur dioxide contributes to acid rain that can devastate forests hundreds of miles from its source.”
(“Pulp (non)fiction: air pollution in the pulp an d paper industry”, http:// www.clarku.edu/activelearning/
departments/economics/gray/grayD.cfm), Anns., Vol. V, Ann. 14.
More generally on these aspects, see Chap. VII, Sec. III. - 7 -
“the collective health of the residents of both riversides will be placed in great,
mediate and immediate peril,... as well as all of the common environmental
resources with the Argentine Republic... The site location of the plants... will
result in an assault to the especially prot ected Eastern riverside of the Río Uruguay
28
and constitutes an irruption or an abrupt territorial invasion . . .”
12 0.19. This is even less acceptable since the River Uruguay, which constitutes the frontier
between the Parties for a distance of some 500km (see Fig.3), has been the subject of a detailed
legal régime protecting not only the respective rights of the two riparian States, but also the aquatic
environment and that of the river and the areas aff ected by it. At the tim e it was established, this
régime was undoubtedly a model of its kind, which still today remains in step with ⎯ and even
ahead of, in some respects ⎯ the general rules protecting in ternational waterways and their
environment, to which, mo reover, it explicitly refers . The Statute of 26 February 1975, a treaty
which is the outcome of a long maturing process, mark ed in particular by the adoption30in 1961, of
the Treaty concerning the Boundary Constituted by the River Uruguay , and, in 1971, by the
Argentine-Uruguayan Declaration on water resources , contains two principal features : 32
⎯ firstly, it prescribes for the Parties a set of materi al obligations aimed at ensuring the rational,
sustainable and equitable utilization of t33 waters of the river, and at protecting its environment
and that of “the areas affected by it” ;
⎯ secondly, to this end, it imposes on the Partie s specific requirements for co-operation, for
example prior notification and consultation if wo rks are planned “which are liable to affect
34
navigation, the régime of the river or the quality of its waters” and where these risk entailing
“any change in the ecological balance” or involve “pests and other harmful factors in the river
and the areas affected by it” . 35

13 0.20. This is undoubtedly so in the case in point. Moreover, be that 36 it may, a joint
settlement has proved impossible, since Uruguay has from the outset decided to proceed
unilaterally, without consulting Argentina a nd without applying the procedures for prior
notification and consultation laid down by the Statute. In particular, regardless of the provisions of
Chapters II, XIII and XIV of the 1975 Statute, it did not inform CARU of its plans before granting
the necessary authorizations, failed to provide it and Argentina, through CARU, with the
information required to fully assess the likely effects of the works on the régime of the river, the
quality of its waters and the areas affected by it, and took no account of the reasoned objections by
Argentina and other bodies which were concerned by the risks resulting from the construction and
37
commissioning of the plants .
0.21. This case therefore relates to a series of varied and numerous breaches by Uruguay of
its obligations under the 1975Statute. It is especially important in terms of protecting the
environment, of which the Court has indicated on several occasions that it:
“is not an abstraction but represents the liv ing space, the quality of life and the very
health of human beings, including generati ons unborn. The existence of the general
obligation of States to ensure that activ ities within their jurisdiction and control
respect the environment of other States or of areas beyond national control is now part
of the corpus of international law relating to the environment.” 38
0.22. By complying neither with the requirements imposed by the 1975Statute in this
respect nor with those to which it refers, Urugua y is damaging the interests of the substantial
human community which depends to a large extent for its sustainable development on the quality
14 of the waters of the river and on the protection of the areas affected by it from pollution. And, by
evading the rules laid down by the Statute rega rding co-operation between the riparian States,
Uruguay is depriving the very content of this treaty of its substance.
0.23. This is all the more concerning because, regardless of the warnings of the Court,
which, in its Order of 13 July 2006, had stressed the necessity for the Parties “to implement in good
39
faith the consultation and co-operation pr ocedures provided for by the 1975Statute” , Uruguay
authorized Botnia on 24 August 2006, still without referring the matter to CARU (or by presenting
it with a fait accompli) and without any consul tation with Argentina, to commission the port
40
associated with the Orion mill and, on 12September 2006, to use for industrial purposes
substantial quantities of water extracted from the River Uruguay . 41

Section IV
Structure of the Memorial
0.24. Given the extremely restrictive position adopted in oral argument by Uruguay as
regards the extent of the Court’s jurisdiction in this case, Argentina is obliged to make a number of
introductory comments on this subject (Chap. I).
0.25. To further clarify the facts set out in Chapter II regarding the origins, existence and
development of the dispute, Chapter III describes the le gal context of the latter, i.e. the set of rules
applicable to the settlement of the dispute, beginni ng with a detailed analysis of the Statute of the
River Uruguay of 1975, particularly in the light of the practice of the States.
0.26. The account of the facts and the description of the applicable law allow the full scale of
15
Uruguay’s breaches of its international obligations to be appreciated, both procedural (Chap.IV)
and material (Chap. V).
0.27. To complete its presentation of the scope of the dispute, the key aspects of which have
been briefly highlighted in this introduction, Ar gentina devotes the next two chapters of its
Memorial to describing:
⎯ both the overall environment concerned by the plan ned mills and their associated facilities, i.e.
the River Uruguay and the areas affected by it, and the specific features of the part of the river
on whose bank Uruguay has unilaterally decided to site the mills that are in dispute (Chap. VI);
and
⎯ the damage that would result from the construc tion and commissioning of the Orion mill and
the associated facilities and, possibly, the CMB mill , whether at the site originally planned or
elsewhere on the River Uruguay or one of its tributaries (Chap. VII).
0.28. Finally, before setting out its submissions pursuant to Article49, paragraph4, of the
Rules of Court, Argentina will indicate in Chapter VIII the remedies called for by the responsibility
that Uruguay has engaged through the breaches of inte rnational obligations that may be attributed
to it. - 10 -
C HAPTER I
JURISDICTION OF THE C OURT
1.1. In its Application, Argentina stated that the jurisdiction of the Court to deal with the
19
present case was based on the first paragraph of Article 60 of the 1975 Statute, under the terms of
which:
“Any dispute concerning the interpretati on or application of the Treaty and the
Statute which cannot be settled by direct negotiations may be submitted by either
Party to the International Court of Justice.”
1.2. During the consideration of Argentin a’s request for the indication of provisional
measures, Uruguay did not contest the jurisdiction of the Court on this basis 42, and the Court found
that “the Parties are in agreement that the Court has jurisdiction with regard to the rights to which
Article 60 of the 1975 Statute applies” . However, Uruguay asserted “that such jurisdiction exists
prima facie only with regard to those aspects of Arge ntina’s request that are directly related to the
rights Argentina is entitled to claim under the 1975St atute”, and insisted “in this regard... that
rights claimed by Argentina relating to any allege d consequential economic and social impact of
the mills, including any impact on tourism, are not covered by the 1975 Statute” . 44
1.3. There is no need to go back over the juri sdiction in principle of the distinguished Court
to deal with the Application under the terms of Article60 of the 1975 Statute (and Article36,
paragraph1, of the Rules of Court), which is accepted by Uruguay and which it could not in any
event go back upon. As pointed out by the Permanent Court:
“If, in a special case, the respondent h as, by an express declaration, indicated
his desire to obtain a decision on the merits and his intention to abstain from raising
the question of jurisdiction, it 45ems clear that he cannot, later on in the proceedings,
go back upon that declaration.”
20 On the other hand, something should be said on th e extent of this jurisdiction and on the precise
role the Court is called upon to perform in the present case, matters on which the Parties could
prove to disagree.
1.4. It goes without saying that Argentina is not in any way claiming, contrary to what
counsel for Uruguay gave to understand at the Cour t’s hearing of 8June 2006, that Article60 of
the 1975 Statute gives “the Court jurisdiction to se ttle any international dispute whatever between
Uruguay and Argentina” 46. Argentina therefore shares Uruguay’s opinion that “the only disputes

covered ratione materiae by the compromissory clause concerned are those relating to the
47
interpretation or application . . . of the Statute” . But it is still essential:
1. not to distort the very subject of Argentina’s Application, as Uruguay is doing; and
2. not to interpret the 1975 Statute in a way that is incompatible with its subject and purpose, as
Uruguay is also doing.
1.5. As regards the first point, a simple reading of Argentina’s Application is enough to
refute the argument that it is onl y claiming breach of “Articles 7 et seq. of the Statute” 48: neither
paragraph2 of the Application, defining the “Sub ject-matter of the Dispute”, nor paragraph24,
setting out the “Grounds of Law Relied on by Argentina”, nor paragraph25 concerning the
“Decision Requested” restrict the subject of the App lication solely to the breach of Article 7 (and
of the procedural provisions immediately following it in ChapterII). Argentina is indeed asking
the Court to find that Uruguay has not complied with the obligations incumbent upon it in this
respect , and that is a key element of its requests, since it entails no less than safeguarding the
50
integrity of the 1975Statute and protecting the River Uruguay and the areas affected by it.
21 However, that is not the end of the list of br eaches of the treaty obligations incumbent on Uruguay
under the Statute which are imputable to it and for which Argentina is seeking reparation.
1.6. Without necessarily being exhaustive, the list of obligations breached by Uruguay ⎯
and expressly or implicitly cited in the Application ⎯ includes at least the following:
⎯ the procedural obligations resulting from Article 1 and Articles 7 to 12 of the 1975 Statute, and
Articles 27 or 34 referring to these;
⎯ the obligations relating to use of the river for navigation (Arts. 3-6);
⎯ the obligations concerning use of the waters of the river, for example for industrial purposes
(Art. 27);
⎯ the obligations relating to management of the soil and woodland, the ecological balance of the
river and the areas affected by it, and the c onservation and preservation of living resources
(Arts. 35-37); and
⎯ the obligations regarding the prevention of pollution (Arts. 40-43).
1.7. Moreover, Uruguay is giving an excessively narrow interpretation both of its obligations
resulting from Article 7 of the 1975 Statute and of the other relevant provisions.
1.8. Under the terms of Article 7, any plan to construct or modify works “which are liable to
affect navigation, the régime of the river or the quality of its waters” requires the State

48
Ibid, p. 34, para. 7; see also p. 37, para. 14.
4Cf. for example para. 25.1 (c) of the Application, whereby Argentina re quests the Court to adjudge and declare
that Uruguay has breached “the obligation to comply with the procedures prescribed in Chap. II of the 1975 Statute”; see
also para. 24 (c).
5On this point, see paras. 1.11 and 1.14 of this Memorial. - 12 -
51
contemplating it to initiate a complex procedure involving CARU and, ultimately, the
International Court of Justice, since “[s]hould the Parties fail to reach agreement within 180 days”
after one of them has come to the conclusion th at the execution of the work “might significantly
impair navigation, the régime of the river or the quality of its waters”, “the procedure indicated in
Chapter XV shall apply” . In this case, however, by failing to submit the plans to construct the
22
CMB and Orion mills and the associated works to CARU, Uruguay has not allowed the process
provided for in ChapterII of the Statute to be started, thereby depriving all its provisions of their
effect, including Article12. The Court nonethel ess has jurisdiction in these proceedings on the
basis of Article60, which entitles it to rule on “ any dispute concerning the interpretation or
application . . . of the Statute” .3
1.9. Strangely, at the hearings concerning Argentina’s request for the indication of
provisional measures, Uruguay claimed that the Court only had jurisdiction to deal with the dispute
arising from the construction and commissioning of the mills at issue in so far as these would result
in an impairment of the quality of the waters of the river and with the consequences “stemming
directly from such impairment by cause and effect” 54. It certainly does, but that is not the sole
form of jurisdiction in the present case.
1.10. Firstly, Uruguay appears to have a peculiarly restrictive view of what is meant by the
expression “régime of the river”. At the heari ngs on the request for indication of provisional
measures, counsel for Uruguay merely stated that “the pulp mills... are not li55le to affect
navigation or the régime of the river; nor does Argentina so claim” . The fact is that Argentina,
both in the Application instituting proceedings 56and the request for indication of provisional
57 58
measures , and in its oral arguments relating to that request , has constantly drawn attention to the
breaches “of the régime of the river” which have the effect of causing damage to the ecology, the
economy and tourism, while distinguishing this, as does the 1975 Statute, from the deterioration of
the quality of the waters of the River Uruguay.
23 1.11. The 1975 Statute was of course concluded to protect the “quality of the waters” of the
River Uruguay but also, more generally, its “régime”. That is why it refers systematically to the
“quality of the waters” on the one hand but also to the “régime of the river” and the areas affected
by it on the other, i.e. all the factors that affect, and are affected by, the ecosystem of the river as a
whole.
1.12. There can be no doubt that the standard s regarding water quality include the standards
and requirements regarding pollution (Arts.41, 42 and43) and the protection of the ecological
balance of the area of the River Uruguay and the areas affected by it (Arts.35, 36 and37).
Moreover, restricting application of the procedure under Articles7 et seq. solely to works
liable to affect the quality of the waters of the river would have the absurd result of authorizing
works which, while complying with those standa rds, would in other respects cause “significant

damage to the other Party” or affect navigation on the river ⎯ something that would be all the
more unreasonable since Article7 specifically requires the parties to enable the other party to
assess “the probable impact of such works on navigation” and since the Articles on that topic
(Arts.3-6) are included in the same chapter (Cha p.II, “Navigation and works”) as the procedural
provisions of Articles 7 to 13.
1.13. Secondly, the procedure laid down by Articles7 et seq. of the 1975 Statute is not
confined to the hypothesis envisag ed in Article7, i.e. the construction or modification of new
channels or works on the river. It is also applicable to:
⎯ use of the waters of the river for domestic, san itary, industrial and agricultural purposes that is
liable to affect the régime of the river or the quality of its waters (Article27 of the
1975 Statute); and
⎯ exploration and exploitation of the resources of the bed and subsoil of the river that are liable to
affect the régime of the river or the quality of its waters (Article 34 of the 1975 Statute).
1.14. Furthermore, the procedure under Articles 7 et seq. must not only be complied with in
24
respect of those works or undertakings affecting the River Uruguay itself, but also all works or
undertakings “which either Party plans to carry out within its jurisdiction in the River Uruguay
outside the section defined as a river and in the areas affected by the two sections” (Articles13
and 29 of the 1975 Statute). The procedure involving CARU provided for by Articles 7 et seq. of
the Statute therefore has a broader applicati on than Uruguay has given to understand and was
established in order to protect the River Uruguay as a system and an ecological whole.
1.15. The compromissory clause contained in Article60 of the 1975Statute thus
encompasses all the breaches committed by Uruguay, i.e. both of the procedural requirements
resulting from Articles 7 et seq. and the material obligations regarding protection of the ecosystem
of the river as a whole 59. In the case concerning Oil Platforms, the Court pointed out that, to
determine whether a dispute relates to the interpretation or application of a treaty, it must “ascertain
whether the violations of the Treaty... plead ed [by the Parties] do or do not fall within the
provisions of the Treaty” . In the present case, each violation cited by Argentina against Uruguay
is based on one or more provisions of the 1975 Statute, including ⎯ but not exclusively ⎯ those in
Articles 7 et seq. concerning the procedure to be followed in cases where one Party plans to
construct works which are liable to affect “the régime of the river or the quality of its waters”. The
Court therefore possesses, by virtue of Article60 of the Statute, the necessary jurisdiction to deal
with all the breaches of the Statute attributable to Uruguay.
1.16. In conclusion:
(i) Article 60 of the 1975 Statute founds the jurisdiction of the Court in these proceedings;
(ii)the proceedings extend to all the breaches attributable to Uruguay of the obligations
25
incumbent upon it under the Statute.

C HAPTER II
O RIGINS ,EXISTENCE AND DEVELOPMENT OF THE DISPUTE
Section I
Introduction
29 2.1. The purpose of this chapter is to explai n the origins of the dispute between Argentina
and Uruguay regarding the pulp mills and associated works on the River Uruguay, the existence of
the dispute, despite its being denied by Uruguay for a time, and how it has developed, including
both the way it has been aggravated by Urugua y through successive authorizations of works and
the efforts made by Argentina to resolve it.
2.2. To this end, it will set out in turn tevents which led to the dispute arising and being
aggravated, as a result of Uruguay’s initial authori zation of 9October 2003 for construction of a
pulp mill (CMB), followed by a second authorizati on of 14February 2005 to construct another
mill(Orion), the authorization of 5July 2005 to construct a port associated with the latter, the
authorization of 24August 2006 for commissioning of this port, and the authorization of
12September 2006 for Botnia to extract and u se water from the River Uruguay for industrial
purposes. Argentina’s attempts to resolve the di spute through direct negotiations and the facts
leading up its referral to the International Court of Justice pursuant to Article 60 of the Statute will
also be presented. Bearing in mind that, for a certain period, Uruguay denied that the dispute
existed at all, this chapter will also demonstrate that this was a mistaken Uruguayan claim.
Section II
The origin of the dispute: the authorization of 9 October 2003
for construction of the CMB mill
2.3. The source of the dispute lies in the authorization granted by Uruguay on
9 October 2003 to the Spanish company ENCE (“Gabenir S.A.” at the time of the authorization) for
30 construction of a pulp mill (a project known as Celulosa de M’Bopicuá or CMB) on the left bank of
the River Uruguay, near the “General San Mar tín” international bridge and the town of
FrayBentos, opposite the Argentine region of Gu aleguaychú. This authorization was issued
despite the fact that CARU had of its own accord asked Uruguay to provide it with information on
the project, so that it could then decide on the c onformity of the works with the Statute of the
RiverUruguay, which would then have allowed Ur uguay to authorize construction of the mill or
61
otherwise .
2.4. Well before the unilateral authoriza tion issued by Uruguay on 9October 2003, the
Spanish company ENCE had approached the Urugua yan authorities with a view to the possible
construction of a pulp mill in Uruguay. On 22July 2002, this company had presented DINAMA
61
See Chap. III, Sec. II.B. - 15 -
with an environmental impact assessment for its CMB project. No information was forwarded by
Uruguay to CARU . 62
2.5. Having learned of the CMB project, CARU requested details from the Uruguayan
Ministry of Housing, Land Use Planning and Environmental Affairs (MVOTMA) on
17 October 2002. The note from CARU pointed out that the area affected by the CMB project “is
an important tourist zone” 63. As will be established below 64, the impact of the pulp mills
authorized by Uruguay on tourism activity in this region bordering the River Uruguay is one of the
major elements in this dispute. CARU re ceived no reply from Uruguay to its request of
17 October 2002.
2.6. On 8 January 2003, DINAMA classified the CMB project as falling within category “C”
of the relevant Uruguayan legislation, i.e. “pro jects entailing activities, constructions or works
whose execution could cause a negative enviro nmental impact of quantitative or qualitative
31 significance, regardless of whether preven tive or mitigation measures are planned” 65. This
decision, as with other information concerning the project, was not communicated to CARU.
2.7. CARU’s Sub-committee on Water Quality and Pollution Control had taken on the task
of monitoring the question of the CMB project and drawn attention to the lack of information on
the project. In February 2003, the Presi dent of the Uruguayan delegation to CARU,
Mr.WalterBelvisi, informed the Sub-committee th at he had met the Uruguayan Minister of the
Environment and asked him for the necessary information concerning CMB. According to
Mr.Belvisi, the Minister66ad given instructions to the Director of DINAMA to forward the
information to CARU .
2.8. In March 2003, CARU’s Technical Secretar iat indicated that it had still not received the
environmental impact assessment or any othe r documentation concerning the CMB project.
Mr. Belvisi67tated that he had contacted both the Minister of the Environment and the Director of
DINAMA .
62Argentina learned of the existence of this document because it is referred to in DINAMA’s final assessment
report of 2 Oct. 2003 (see this DINAMA report in the Anns., Vol. V, Ann. 12, and in: Pulp Mills on the River Uruguay
(Argentina v. Uruguay), Observations of Uruguay, 2 June 2006, Exhibit 1, DINAMA Ann. 9).

2.9. At its meeting of April 2003, the S ub-committee informed CARU that, although it had
made contact with DINAMA and requested info rmation, it had receive d no reply from the
68
Uruguayan authorities .
32 2.10. In 69ew of Uruguay’s silence, CARU fo rmally repeated its request for information on
21 April 2003 . At its meeting of 13May 2003, the Sub-committee noted that it had still heard
nothing regarding the CMB project . 70
2.11. DINAMA finally replied on 14May 2003, but by suggesting to CARU that it should
contact one of its staff, who in turn suggested forwarding the document entitled “Environmental
Impact Assessment, Celulosa de M’Bopicuá. Su mmary for Public Release”, which was already
71
publicly available on DINAMA’s website . This document, produced by the Soluziona company,
was received by CARU and forwarded to the Sub-committee on Water Quality and Pollution
Control, which distributed it to the Parties . 72
2.12. On 16July 2003, CARU received a note from DINAMA informing it of a public
meeting to be held at Fray Bentos on 21 July 2003 concerning the request for initial environmental
authorization of the CMB project . 73
2.13. The technical secretary of CARU and its legal adviser attended the public meeting and
reported to CARU on the discussions that had take n place. They concluded that, once the various
positions had been established (for and against the setting up of the mill), “the need emerged for the
studies to be extended, so that they were of a qua lity that would allow decisions to be taken that
74
were not damaging to the environment and its habitat” .
75
33 2.14. On 15August 2003, the President of CARU , Mr.Belvisi (Uruguay), wrote again to
the Uruguayan Environment Minister informing hi m that more information was essential. In
particular, this note from CARU pointed out to the Uruguayan Minister that:
“In accordance with the decision of th is Commission, pursuant to the powers
both Governments awarded to CARU in Articles7 to12 of the Statute of the
RiverUruguay, and bearing in mind the im portance that the future undertaking will
generate within CARU, a study was conduc ted on the above-mentioned document.
This evidenced the need to have further de tails and information on the environmental

impact assessment study beyond what is provided in the document ‘Environmental
Impact Study, Celulosa de M’Bopicuá. Summary for Public Release’.
Consequently, we request that the following data be included, in addition to any
information you may consider relevant:
⎯ Water quality data generated and collected which were used in the study.
Analytical protocols used, including detection/quantification limits.
⎯ Characteristics of the liquid effluent diffusion system within the collector body
(emissary).
⎯ Data on entrance and simulations on the emissary diffusion plume. Model used.
⎯ Entry data and simulations made on the movement of pollutants downstream of
the discharge point. Model used.
⎯ Data on determination of AOX (absorbabl e halogenated organisms), frequency of
their determination and matrix for the control of effluent and aquatic medium.
⎯ Detailed plan of follow-up and control of environment and liquid effluent.
Any further information you may consider useful for the requested purposes
(possible influence of discharged effluents on water).” 76
2.15. No further information was received by CARU. At its meeting of September 2003, the
Sub-committee on Water Quality and Pollution Control once again proposed “repeating the request
77
for information to DINAMA” .
2.16. On 8 October 2003, the Sub-committee on Water Quality and Pollution Control stated
in its report No. 240 to CARU:
34 “The President of the ERU (Uruguay) delegation reports that the Uruguayan
Minister of Housing, Land Use Planning and Environmental Affairs, Mr. Saúl Irureta,
has informed him that in the next few da ys, he will send us the report on M’Bopicuá
78
produced by DINAMA, which the company is in the process of ‘checking’”.
2.17. Without informing CARU in adva nce, MOVOTMA79roceeded to grant ENCE
authorization to construct the CMB mill on 9October 2003 . That same day, the President of
Uruguay, Jorge Battle, had promised his Argentine c ounterpart Néstor Kirchner, at a meeting held
in Colonia (Uruguay), that no authorization would be issued before the environmental concerns of
Argentina had been met. Previously, a similar promise had been made by the Uruguayan Minister

CARU had given its opinion on the report being drawn up by DINAMA .
2.18. On 10October 2003, CARU approve d the above-mentioned report No.240 of the
Sub-committee on Water Quality and Pollution Control. Unaware of the authorization issued by
Uruguay the previous day, and referring to the urgent requests from the Uruguayan delegation for
its government to send the necessary information, the President of CARU,
Ambassador García Moritán (Argentina), declared that he “appreciated what had been done by the
Uruguayan delegation to ensure strict compliance with Article7 of the Statute, so that the
consultation procedure that was laid down there could take place.” And the President added:
35 “Once we are in possession of the material, which we hope DINAMA will be
forwarding to us as soon as possible, the appropriate technical meetings will be held to
carry out the studies and assessments relati ng to the project, in accordance with the
procedure laid down in Article 7.” 81
2.19. The Uruguayan delegation made no comment. Nor did it inform CARU that the
authorization had been issued the previous day.
2.20. A few days later, the Argentine Embassy in Montevideo learned unofficially of the
existence of an authorization for construction an d informed the Argentine delegation to CARU.
The Argentine delegation immediately requested an extraordinary meting of CARU.
2.21. On 17 October 2003, the extraordinary m eeting of CARU took place to deal with the
situation created by the authorization of construction of the CMB mill. The President of CARU,
Ambassador García Moritán, expressed his surpri se on learning through the Argentine Embassy in
Montevideo that the Uruguayan Environment Mini ster had authorized the construction of CMB
without referral to CARU, in breach of Article7 of the Statute. The CARU President explicitly
cited Article 12 of the 1975 Statute (which refers to the procedure for submission of disputes to the
ICJ) “in the event of differences of opinion”, c oncluding that: “the MVOTMA resolution should
have been adopted after application of the mechanism laid down [by the 1975 Statute]” 82.
2.22. The Uruguayan delegation did not contradi ct the Argentine stance. The President of
the Uruguayan delegation replied by simply stating that: “as a delegation, we are not in a position
to put forward or express any other kind of views, since we do not have all the materials, not even
those that could be forwarded to the Commission as antecedents” 8. The President of the
Uruguayan delegation added that he was not familia r with the Ministry’s resolution, that his

the statement that “when the Minister of Foreign Affairs, Mr. DiOpertti, was presented with the concerns on the
subject, he emphatic ally stated that no deciswould be taken until the Administrative Commission of the River
Uruguay (CARU) had given its opinion on the Environmental Im pact Assessment report submitted to the Department of
the Environment (DINAMA)”.

CARU]” .
2.23. On 27 October 2003, the Uruguayan Ministry of Foreign Affairs sent a note to the
Argentine Government, attaching the MVOTMA resolution of 9October 2003, DINAMA’s final
assessment report of 2October 2003 and the imp act study of 22July 2002 produced by the
construction company. The Ministry justified th e forwarding of this information simply on the
basis of “the spirit of co-operation and good neighbourliness which happily marks the relations
85
between Uruguay and Argentina” . No reference was made to CARU or to the 1975 Statute. This
documentation is also far from constituting the information required under the Statute . 86
2.24. That same day, the Argentine Government responded by declaring that such an
authorization was not in accordance with the 1975 St atute and other rules of international law, and
that the information forwarded did not a87ear sufficient to allow a decision to be made on the
environmental aspects of the project .
2.25. Uruguay replied to this note on 7 November 2003, merely forwarding a dossier from
MVOTMA on the CMB project but without responding to the objections contained in the
88
Argentine note of 27 October 2003 concerning Ur uguay’s conduct in breach of the 1975 Statute .
Uruguay thus did not reconsider its position, which is to deny CARU’s jurisdiction to decide on the
pulp mill project. Hence Uruguay neither referred the project to CARU nor provided any further
37 information. As a result of this situati on, which prevented CARU from carrying out its
responsibilities, CARU suspended its work for more than six months.
2.26. On 26 November 2003, Uruguay’s Minister for Foreign Affairs, Didier Opertti, made a
statement before the Senate’s Foreign Affairs Committee explaining the Uruguayan Government’s
point of view, which proved to contradict outri ght the stance adopted by Uruguay’s delegation to
CARU. For the Minister, these were entirely natio nal works and therefore “subject solely to the
Uruguayan legal order” 8, which ruled out, in his view, the application of ChapterII of the
1975 Statute. As he explained:
“given that they are not bi-national, th e only reason or basis whereby these works or
this mill ⎯ or others like them ⎯ could involve the responsibilities of a bi-national
body such as the Administrative Commission of the River Uruguay would be if the
planned construction works were to jeopardize ⎯ according to the provisions of
Articles 7 and 8 of the Statute of the River Uruguay ⎯ the quality of its waters or the
navigability of the river . . .

the Minister for Foreign Affairs, Mr. Didier Opertti, Anns., Vol. VII, Ann. 4. - 20 -
The Administrative Commission of the River Uruguay is responsible for the
management of the River Uruguay, in other words of a shared natural resource. That
responsibility has never been called into questio n; it clearly has that responsibility.
Recognizing that the Commission has a specifi c responsibility at this stage of the
procedure would amount to recognizing the presumption that Articles 7 and 8 will be
applied. The presumption is that implementation will affect or could affect ⎯ I think
the term used in the rules is: there will be a definite risk to ⎯ the quality of the waters
or navigation. Given that these two elemen ts are lacking, it is natural that the
Government of Uruguay should not be obliged to refer this matter to the Commission.
That would be abandoning our responsib ilities,90hich the Government of Uruguay
does not intend to do; it is as simple as that.”
2.27. The current President of the Uruguayan delegation to CARU, MsMarthaPetrocelli,
explained in her statement to the Envir onment Committee of the Uruguayan Senate on
12 December 2005 why Uruguay had decided not to submit the CMB mill plan to CARU. In doing
so, she confirmed that the intention of the Urugua yan Government had been to deliberately avoid
38
application of the 1975 Statute. The conversati on between MsPetrocelli and the members of the
Environment Committee is very revealing on this subject:
“Mr. LAPAZ: The matter was dealt with: so did the pulp mills seek prior
authorization from CARU? Or was the matter raised by one of the members?
Ms PETROCELLI: The matter was raised by the Argentine delegates and
accepted by the Uruguayan delegates, but there was no formal submission. Moreover,
according to Article 7, it is the State which must make the submission. This particular
case came up by surprise. It is the Party ⎯ diplomatically speaking ⎯ which has to
give notification that it is going to carry out construction work ⎯ private or public ⎯
and announce it in sufficient time. I have b een thinking recently that today, time is a
serious issue; the timescales are much tight er now than when the Treaty was signed.
We are talking about the 1946Treaty, when announcements could be made well in
advance. But there was not really a notification by the Party; the requirement is not
on the individual firm, it is for the Party to notify CARU.
The PRESIDENT: Article7 refers to the need for CARU to be consulted and
for the two delegations to give their consent to the plan in question. The legal
interpretation is to the effect that si nce there was no element that could cause
contamination, this prior consent was not necessary. Is that the right interpretation?
Ms PETROCELLI: If you read Article7 carefully, a solution can be found
which, like all those in international public law, is a somewhat ambiguous
compromise that could fill several libraries. Also, what is contained in Article7 is a
principle of international public law. Wher e there is a shared or successive river,
consultations take place on the works without any involvement of the Statute. Party A
is responsible for the construction works; it consults PartyB, which has the time to
talk or otherwise; so it does not have to indicate straight away that significant damage
is involved, and it may later ask for the project to be extended. That means that this is
not a very clear stage. I have even looke d at the international case law, which states
that if there is disruption, that is not a reason to stop anything, which amounts to
saying that there has to be clear damage.
So the system would be as follows: first the project is announced at the plant, I
allow some time, the information comes b ack to me, and only then do I submit the
90
Ibid. - 21 -
project. It seems to me that in the case of the port, I still have some time. So this prior
consent to eliminate the consultation is not very viable. That is my humble opinion.
39 The PRESIDENT: The Argentines want to take the matter to the OAS
(Organization of American States).
Ms PETROCELLI: Yes indeed. I spoke to the Argentine Ambassador, in a
relaxed and friendly atmosphere, and I said to him: ‘I hope you manage to get to
TheHague, because I shan’t be there. With any luck, in 2020.’ Because there is an
issue of time in taking things to The Hague. There is also a reality when it comes to
positioning before international tribunals, and sometimes things do not turn out as you
wish. I am giving my opinion here. But it is a valid approach. Legally, one can turn
things round and round with regard to setting up new bodies. We hope that everything
will be worked out in a different way. The point is that Uruguay has been untimely in
dealing with this matter. That is the truth of it.
The PRESIDENT: One of the arguments put forward is that if consultation had
taken place, the answer would have been no. That is an awkward point. What would
have happened if the answer had been no?
Ms PETROCELLI: The works would not have been carried out. We would
have had to refer the matter to an interna tional tribunal to establish what damage was
caused by a decision to reject.”91
2.28. In view of the situation created by Uruguay’s attitude, the Argentine delegation tried to
break the deadlock in CARU. The President of th e delegation wrote to the President of CARU on
23 February 2004, forwarding to the Commission the documentation which Argentina had received
from Uruguay regarding the CMB project. He al so asked for this to be referred to the
Sub-committee on Water Quality and Pollution Contro l, to assess to what extent the planned mill
and its commissioning might affect the quality of the waters of the River Uruguay, “without
prejudice to the issues raised by the Argentine de legation regarding Article 7 of the Statute of the
River Uruguay at the extraordinary plenary meeting of 17 October 2003” . 92
2.29. In the meantime, CARU remained dead locked because of this disagreement. On
2 March 2004, the Foreign Ministers of the two c ountries, Rafael Bielsa and Didier Opertti, met in
40
BuenosAires, in the context of a meeting on bila teral and regional affairs. As regards the CMB
project, they reached a verbal arrangement in or der to resolve the impasse within CARU. Under
this arrangement, Uruguay undertook to forward the information required to CARU and, while
awaiting this, CARU would carry out water quality monitoring in the region where the CMB
project was planned.
2.30. Mr.Bielsa summed up the content of the arrangement of 2March 2004 with his
Uruguayan counterpart as follows when he appeared before the Foreign Affairs Committee of the
Argentine Chamber of Deputies on 14 April:
“With regard to M’Bopicuá, the agreem ent we have entered into with Uruguay
will have three stages. The first stage ends with the approval of the works. This stage

involves a specific body, the Administrative Commission of the River Uruguay
(CARU), and here Argentina will receive a ll the information from Uruguay. As we
know, Argentina has presented two reports on the environmental impact, and both
include plans to combat this. The second stag e, which is that of construction, will last
four years. Argentina has a right of inspection, an element which is not without
importance, since the point here is that technological processes exist which make it
possible to reduce the environmental conse quences in a very significant way. But
plants which have these technologies bear much higher costs. Uruguay, as a green
country, sixth in the world in terms of protecting the environment, takes these
concerns seriously into account.
It seemed to me that we could claim th is right of inspection under the Treaty of
the River93ruguay, and it is the Commiss ion that will monitor the construction
works.”
There is no doubt that the first stage referred to by Mr. Bielsa is the one leading to approval
41
of the project , during which Uruguay was required to fo rward the relevant information to
Argentina, through CARU. This is no more a nd no less than the effective implementation of
Article 7.
2.31. Following this arrangement, Argentina convened an extraordinary meeting of CARU,
which was held on 15 May 2004. The President of the Argentine delegation explained that the
reason why his delegation had asked for an urgent extraordinary meeting to be convened was that it
wished “to call upon this body to engage, as a matter of urgency, the environmental responsibilities
granted to it by the Statute, in particular those arising from the construction of a pulp mill near Fray
Bentos (Uruguay), ‘Celulosa de M’Bopicuá’” . 94
2.32. The content of the Bielsa-Opertti a rrangement was summarized as follows within
CARU:
“On 2 March 2004, the Ministers of Fo reign Affairs of Argentina and Uruguay
came to an understanding on how to take this matter forward, namely the provision of
information by the Government of Uruguay re garding construction of the mill and, in
93
Minutes of the meeting of the Minister for Foreign Affa irs, Rafael Bielsa, with the Foreign Affairs Committee
of the Chamber of Deputies, Buenos Aire s, 14 April 2004. Anns., Vol. VII, Ann. 11. Also cited in: Uruguay, Ministry
of Foreign Affairs, report on the construction of two cellulo se plants on the River Uruguay, Montevideo, 23Feb.2006,
in: http://www.mrree.gub.uy/mrree/Asuntos_P oliticos/Planta%20Celu/informe.htm. This same version of the verbal
arrangement was included in the Argentine report on the Sate of the Nation 2004, which refers to the matter in two
separate paragraphs. The first appears under the heading “Uruguay”, the second under the heading “CARU” (Presidency,
Cabinet Office [Jefatura], report on the State of the Nation 2004, Buenos Ai res, 1 March 2005, p. 106. Anns., Vol. VII,
Ann. 18). In accordance with Art. 104 of the Argentine Cons titution, ministers present a report on their activities during
the previous year at the start of the legislative period, which be gins annually on 1March. The verbal arrangement was
also reflected in two reports by the Head of the Cabinetffice to the Argentine Congress (report by the Head of the
Cabinet Office, Dr. Alberto Angel Fern ández, to the Honourable Chamber of Deputies of the Nation, report No.64,
Marc2h005, p3.79, Anns., Vl.II, Ann1.9, and report by the Head of the Cabinet Office,
Dr.AlbertoAngelFernández, to the Honourable Chamber of Senators of the Nation, report No.65, June2005, p.528,
Anns., Vol.VII, Ann.20). During the provisional measures phase, Uruguay se nt the Court a deliberately truncated
version of the relevant passages, both in the original langu age and the English translation, without providing the Court
with the whole text as required by Art.50 of the Rules ofCourt. This conduct is all the more regrettable since the
passages deliberately omitted are crucia l for a correct understanding of the ment, and their absence alters the
meaning of its content.

operational terms, the monitoring of wate r quality by CARU in accordance with its
95
Statute.”
2.33. Still referring to the CMB project, the two delegations:
“reaffirmed the arrangement made by the Ministers of Foreign Affairs of the
Argentine Republic and the Eastern Republic of Uruguay on 2 March 2004, whereby
Uruguay will communicate information on the construction of the mill, including the
42 environmental management plan. As a resu lt, CARU will receive the environmental
management plans for the construction a nd commissioning of the mill submitted by
the company to the Uruguayan Government, once they have been forwarded by the
Uruguayan delegation. CARU will study th ese in the context of its responsibilities,
taking account of the terms contained in th e above-mentioned Ministerial Resolution
No.342/2003, in particular those indicated by the Ministry of Housing, Land Use
Planning and Environmental Affairs as measures requiring implementation and
additional studies by the company before approval, at the same time drawing up
observations, commentaries and contributi ons which will be forwarded to the
Uruguayan Government to be dealt with and resolved with the company. Once these
steps have been taken, CARU will be informed further.” 96
2.34. The decision adopted at the extraordinary meeting of CARU on 15May 2004 was as
follows:
“On the basis of the above, as set out and agreed by the Parties, it is decided to
forward all the documentation held by CARU on the M’Bopicuá project to the
sub-committee on water quality and pollution control, for analysis and assessment as
indicated under Specific Conclusions I and II on pages 34 and 35. It is also agreed to
request all information on the construction stage, in accordance with the undertakings
given by Uruguay’s Minister of Foreign Affairs. In this context and in accordance
with the Environmental Protection Plan, it is agreed to convene the Committee of
technical consultants for the relevant purposes.” 97
2.35. The President of the Argentine delegation pointed out that he had indicated in his note
to the President of CARU of 23February 2004 that he was forwarding to CARU the Uruguayan
documentation on the construction of a cellulose plant at Fray Bentos that had been provided by
Uruguay’s Ministry of Foreign Affairs to the Ar gentine Embassy in Montevideo, asking for the
Sub-committee on Water Quality and Pollution Control to begin work on this documentation, so as
to assess to what extent the planned works and th eir commissioning might affect the quality of the
waters of the River Uruguay. As indicated, this note clearly stated:
43 “Toregoing is subject to the issues previously raised by the Argentine
delegation regarding Article 7 of the Statute of the River Uruguay at the extraordinary
plenary meeting of 17 October 2003.” 98
95CARU, Minutes 1/04, extraordinary meeting of 15 May 2004 convened by Argentina, p.34. Anns., Vol.III,

96Ibid., pp. 34-35.
97

98Emphasis added, ibid., p. 4. - 24 -
2.36. He was thereby referring to Argentina’s view that Uruguay had breached the
requirement laid down by Article 7 of the 1975 Stat ute, as expressed at the extraordinary meeting
of CARU convened for the purpose by Argentina. After drawing attention to the lack of
information on a number of aspects, the President of the Argentine delegation emphasized that “it
is important for CARU to act in accordance with the provisions of the Statute and for it to carry
out, pursuant to this mandate, the studies it may consider to be lacking” . 99
2.37. The Argentine delegate Mr. Rodríguez pointed out that Argentina had protested at the
failure to comply with the consultation procedure laid down by Article7 of the Statute. Another
Argentine delegate, Mr. Rojas, stressed that:
“the procedure set out in Article7 and the following articles is essential to assess
whether the works planned by one Party on a shared natural resource like the
River Uruguay are likely to cause significant damage to the other. For this reason, one
should expect as a matter of course a proce dure that includes adequate information,
one that shows genuine involvement, leading step by step to a solution based on
completely sound reasoning and co-operation between the two countries; a procedure
that analyzes the direct and cumulative effects which this project may have on the
environment, taking account not just of th e use or modification of precious natural
resources, but also of other development options that might be affected by the
construction and future commissioning of Celulosa de M’Bopicuá.” 100
2.38. The Uruguayan delegate Mr. Cardoso welcomed the fact that the two ministers’ views
101
had moved closer together and felt that this would “help find a way to resolve the dispute” . He
emphasized that the Uruguayan delegation did not entirely share the conclusions of Argentina’s
44 technical experts, and that the Uruguayan reports, which were of no lesser technical value, did not
reach the same conclusions. The same delegate repeated that the Uruguayan delegati102did not
agree with some of the analyses contained in the reports by the Argentine delegates . Clearly, the
Uruguayan delegation recognized that the dispute over the planned mill had not been settled at that
stage.
2.39. Argentina explicitly reserved its positi on as regards the non-compliance with Article 7
of the Statute and the need for this to be comp lied with. The Parties noted their differences, but
agreed that Uruguay had to supply further information, that this would be examined by CARU, that
CARU would forward its observations to Uruguay, that Uruguay would deal with these issues with
ENCE, and that CARU should then be informed fu rther. CARU thus restated its responsibilities
under the Statute and the requirement for the procedur e laid down in Chapter II to be followed. At
no point during this extraordinary meeting, nor at any other meeting of CARU, was the
construction of the mill approved or a decision taken on whether the project might cause significant
damage to the other Party. This is in clear c ontrast to the procedure which CARU follows when it
approves the imple103tation of a project, as shown for example by resolution12/01 concerning
Port M’Bopicuá .

2.40. Clearly, the procedure had not in any ev ent reached the stage of a decision being made
by CARU. On the contrary, as explicitly stated in the arrangement of 2 March 2004, Uruguay was
to forward further information to CARU, which presupposes that no decision could be taken before
that information had arrived. But that information has never been received by CARU.
2.41. The information available was not suffici ent to enable CARU to reach a decision in
accordance with Article7 of the Statute. The Parties disagreed on a number of questions of
substance. They stated this explicitly on 15 May 2004. In reality, the agreement between the two
45 Ministers was to comply with the procedure under the 1975 Statute, thereby ending the dispute on
CARU’s jurisdiction to deal with the CMB pr oject. Uruguay has not kept its undertaking of
2 March 2004. Its subsequent behaviour has unfortunately prevented such a settlement from taking
place and on the contrary has aggravated the dispute.
2.42. While awaiting the information promised by Uruguay’s Minister for Foreign Affairs to
his Argentine counterpart, CARU drew up and approved a plan which provided for increased
monitoring of the quality of the waters of the River Uruguay in the area of the CMB project, near
Fray Bentos. Hence Argentina kept its side of the verbal arrangement.
2.43. The Sub-committee immediately began the preparatory work for monitoring the quality
of the waters in the area of the CMB project. Monitoring of the biota was added to the usual
monitoring of water quality 104. The plan for water quality mon itoring was subsequently split up,
and a self-contained plan for monitoring the qualit y of the waters in the area where the mill is
105
planned (“PROCEL”) was adopted by the Sub-committee on 11November 2004 . The
information on the construction of the CMB mill that was promised by the Uruguayan Minister
Mr. Opertti has never reached CARU.
2.44. Uruguay claims that these efforts by Ar gentina to settle the dispute which arose in
October2003 indicate that it had been resolved. Nothing is further from the truth, as will be
demonstrated in the following sections of this chapter.
Section III
46
The aggravation of the dispute: the authorization of 15 February 2005
for construction of the Orion mill
2.45. The dispute that arose in October 2003 had not been resolved. By not forwarding the
information that was required, Uruguay never enable d CARU to begin the procedure laid down in
Chapter II of the 1975 Statute 106. In fact, by authorizing the construction of a second mill less than
a year later, without following the procedure laid down by the 1975 Statute, Uruguay purely and
simply rejected the agreement of 2 March 2004.
2.46. On a date not known to Argentina, the Finnish company Botnia contacted the
Uruguayan authorities with a view to constructing a pulp mill in the area of Fray Bentos. On

30October 2003, DINAMA classified this project as falling within category“C” of the relevant
Uruguayan legislation 107. On 31 March 2004, Botnia submitted its request for initial environmental
108
authorization, which was supplemented on 7 April 2004 .
2.47. On 29 and 30April 2004, Botnia he ld a meeting with members of CARU in
Montevideo to explain its plan for a pulp mill 109. At its meeting of 15June 2004, the
Sub-committee on Water Quality and Pollution Cont rol considered the possibility of holding a
further meeting, so that Botnia could expand on the information previously provided. On this
occasion, “[t]he Argentine delegation stressed th110 importance of the consu ltation procedure laid
down by the Statute of the River Uruguay” .
2.48. In August 2004, CARU delegates were invited by Botnia to visit Finland. CARU
47 111
delegates likewise travelled to Spain at the invitation of ENCE in September 2004 112 Members of
CARU also went to Argentina and Brazil to visit areas where pulp mills are located .
2.49. On 18 October 2004, the Presidents of th e two delegations met and decided to set up a
new subcommittee, the “Sub-committee on the Environment and the Sustainable Use of Water”,
which would be responsible for the plan for mon itoring water quality in the areas of the cellulose
mills 11.
2.50. On 19 October 2004, CARU held a me eting with representatives of Botnia. CARU
114
stressed the need for it to have information on the procedure under way with DINAMA .
2.51. Consequently, in a note to DINAMA of 16November 2004, CARU indicated that it
had been informed of Botnia’s moves to obtain authorization for construction of a pulp mill and
115
asked DINAMA to provide it with the relevant information . This note from CARU has never
received a reply.
2.52. On 21 December 2004, DINAMA organized a public information meeting in
116
Fray Bentos on the Botnia project. One of CARU’s consultants took part in this . His report to

the Sub-committee on Water Quality and Pollution Control confines itself to describing how the
117
meeting was conducted .
48 2.53. On 11 February 2005, DINAMA produced its environmental impact study of the pulp
mill plan submitted by Botnia. Even though pointi ng out that the scheme put forward by Botnia
contained “information gaps, cont radictions (even within the sa me document) and vague, rather
118
unsatisfactory replies”, DINAMA declared itself in favour of authorization . The DINAMA
study was not forwarded to CARU.
2.54. Despite the flaws in the mill identified by DINAMA, on 14February 2005 ⎯ three
days after the date of the impact study referre d to above, and two weeks before the change of
government in Uruguay ⎯ MVOTMA adopted resolution No. 6119005, granting Botnia initial
environmental authorization for its pulp mill project . No decision had previously been taken by
CARU, and nor was it subsequently informed of this authorization. The outgoing Uruguayan
Government was therefore aware that, by granting Botnia authorization for the Orion project on
14 February 2005, without referring this to CARU, it was going to aggravate the dispute.
2.55. At the meeting of CARU of 11Marc h 2005, the Vice-President of the Argentine
delegation announced with regret that he had learned through the media that Uruguay was said to
have authorized Botnia to construct a pulp mill without going through CARU, and furthermore
without replying to its request for information. The President of the Uruguayan delegation himself
confirmed that his delegation did not know of the authorization, but that he was aware of the media
reports to which his Argentine colleague had refe rred. This was an exact repetition of what had
taken place within CARU when Uruguay authorized CMB. Following a proposal by Uruguay,
49 CARU decided to repeat its request for information to DINAMA of 16 November 2004, which had
not received a reply 12.
2.56. Also in March 2005, answering a question from a senator, the Head of the Argentine
Cabinet Office explained in his report No. 65 to the Senate:
“(a) The Government has received the environmental impact assessment regarding a
pulp mill planned by the Spanish company ENCE, which shows that there will be
liquid and gaseous discharges affecting th e waters of the River Uruguay and the
atmosphere of the Province of Entre Ríos. However, this assessment ⎯ produced
at the request of the ENCE company ⎯ does not take account of the
environmental impact of these emissions on our national territory, and must
therefore be extended. Moreover, no equi valent documentation has been received
concerning the Botnia mill, which is on a much larger scale. An assessment is
needed of the environmental impact of the pulp mill complex planned on the left
bank of the River Uruguay, as the two mills should be seen as a single unit from
the environmental point of view.

(b) Information has been requested from the Government of the Eastern Republic of
Uruguay on numerous occasions. But the administrative process for authorizing
construction of the mills has taken pl ace without respect for the norms of
international law, in particular those laid down by the Statute of the
River Uruguay.
(c) The Argentine Government has not been involved in the pr121ss for authorizing
these mills. It has not even been consulted in this respect.”
2.57. This report contains a detailed account of the background to the dispute and of
Argentina’s efforts to ensure that CARU was given responsibility for handling the CMB project.
The report also explains the deadlock within CA RU because of the lack of consensus on dealing
122
with the issue of Uruguay’s unilateral authorization . It adds:
“The Argentine delegation to CARU, wh ere meetings were still suspended,
received the documents [those concerning the authorization for CMB] through its
Ministry of Foreign Affairs, which also asked for these to be considered by the
Administrative Commission of the River Uruguay (Note No.10ó[sic]/2004 of
50 24February 2004). There was no consensu s on this move either, given Uruguay’s
refusal to allow CARU to start considering the matter.” 123
Section IV
The creation of the GTAN and further aggravation of the dispute
through Botnia being authorized to construct a port
2.58. On 1 March 2005, the change of government took place in Uruguay. During his first
visit to Argentina, the new Uruguayan President, Tabaré Vázquez, and hi s Argentine counterpart
Néstor Kirchner decided on 5 May 2005 to set up a high-level working group (GTAN) with a view
to settling the dispute, on the basis of an environmental impact assessment for the two planned pulp
mills, CMB and Orion.
2.59. On the same day, in the context of this presidential meeting, the Argentine Minister for
Foreign Affairs, RafaelBielsa, delivered a not e on the planned pulp mills to his new Uruguayan
counterpart Reinaldo Gargano, asking him to:
⎯ consider the relocation of the mills;
⎯ provide more documentation on them;

Report by the Head of the Cabinet Office, Dr. Alberto Angel Fernández, to the Honourable Chamber of
Senators of the Nation, report No.65,June 2005, pp. 616-617. Anns., Vol.V II, Ann.20. During the provisional
measures phase, Uruguay presented a deliberately truncated version of the relevant passages, both in the original
language and the English translation, without providing the Court with the whol e text as required by Art. 50 of the Rules
of Court. This conduct is all the more regrettable se the passages deliberately omitted are crucial for a correct
understanding of the document, and their absence alters the m eaning of its content. Uruguay reproduced only two of the
six and a half pages of the second report of the Ministry of Foreign Affairs that appears in report No. 65, of which it only
translated a single paragraph. This second report contains a detailed account of the background to the dispute and does
not allow the conclusion that the arrangement of 2 March brought an end to the dispute over the project. - 29 -
⎯ maintain the status quo for 180 days to allow st udies to be produced of the cumulative impact
124
on the environment .
There has never been a formal reply to this note from Argentina.
51 2.60. The following day, 6May 2005, CARU held a meeting. The President of the
Argentine delegation raised an issue before th e start of the agenda, pointing out that the
consultation procedure laid down by the Statute (Art. 7 et seq.) had not been complied with in the
case of either the CMB or the Orion project. Afte r recalling the sequence of events, the President
of the Argentine delegation continued as follows:
“The main reason for reminding you of this background is the ongoing concern
at the fact that the aforesaid prior consu ltation mechanism has not yet been applied.
Regrettably, the CARU cannot adequately fulfil its tasks if it does not receive all the
technical information. In the case of Bo tnia, it has not received data for the
assessment and for determining on a technical basis whether this project generates a
substantial environmental effect, as the Statute of the River Uruguay points out in the
relevant sections. I would also like to remind you that in the case of M’Bopicuá, the
CARU did not receive the relevant data through the usual channels, it was instead
through the Argentine delegation that it received such data. We have exchanged ideas
on several occasions with the Uruguayan delegation, always encountering the most
constructive and responsible spirit for the ha ndling of such issues, and the Argentine
delegation cannot do anything other than e xpress its gratitude as to the manner in
which such issue has been submitted before its relevant authorities. However, we
must mention that the prior consultation mechanism was not observed, and this is
serious. The CARU has sent notes to the relevant Uruguayan bodies, and the
Argentine delegation expresses its appreciati on for such steps and requests additional
data on the installation of the M’Bopicuá unde rtaking, and on Botnia. We regret not
having received an answer. We regret to see that the consultation system provided for
in the Statute of the River Uruguay is not being implemented and that the CARU
cannot benefit from such system. It is the intention of our delegation to raise the issue
once again, as it significantly affects seve ral communities on the Argentine coastline
on the River Uruguay, and it is obvious that the Uruguayan coastline will also suffer
from such effects. It is obvious that br each of the Statute as regards the prior
consultation system (Articles7 et seq.) is a very serious matter. It is obvious that
should such situation continue, the proce dures provided for in the Statute for settling
disputes concerning the application of rules pr ovided for therein must be triggered. I
wish to point out that we make a reservation of rights in this regard. We once again
request the Uruguayan delegation to comply with the prior consultation system as
regards BotniaS.A. so that the CARU and the Argentine delegation in particular can
analyze whether the projected works involve environmental effects that require
125
corrective measures in accordance with the Statute of the River Uruguay.”
Argentina thus reserved the right to activate the procedures laid down in the Statute for the
settlement of disputes, if the situation were to continue, i.e. to apply the judicial settlement
procedure provided for in Articles 12 and 60 of that Treaty.
It is worth noting the response from the President of the Uruguayan delegation, confirming
52 Argentina’s view: “the facts have occurred as Mr.Ambassador [García Moritán, President of the
124
Note of 5 May 2005 from the Argentine Minister for reign Affairs, Mr. Rafael Bielsa, to the Uruguayan
Minister for Foreign Affairs, Mr. Reinaldo Gargano. Anns., Vol. II, Ann. 22, which refers to the “planned” installation of
two mills.

CARU, Minutes 5/05 of 6 May 2005, pp. 966-968. Anns., Vol. III, Ann. 32. - 30 -
126
Argentine delegation] has explained” . This is another clear acknowledgment by Uruguay that it
did not follow the procedure laid down in Chapter II of the Statute.
127
2.61. On 31May 2005, the Foreign Ministers formally set up the GTAN . The first
meeting scheduled for 5 July 2005 in Montevideo was cancelled by the Uruguayan Government 12.
Argentina then proposed holding this first meeting on 12 July 2005. This proposal was rejected by
Uruguay, which would not agree to the GTAN starting work unless Argentina withdrew its note of
26 June 2005 to the President of the World Bank. This note expressed the Argentine Government’s
concern at the possibility of the International Fi nance Corporation (IFC) deciding to finance the
construction of the CMB and Orion mills before the GTAN had carried out the cross-border impact
studies and despite Uruguay’s failure to comply with the provisions of the 1975 Statute 129.
2.62. The construction work on the Orion m ill began in the second half of 2005. Botnia
sought to move as swiftly as possible to the construction phase. At the same time, ENCE had
begun work on the groundworks for construction of the CMB mill.
2.63. On 5July 2005, the Uruguayan Government authorized the Botnia company to
construct a port terminal in the area of its Orion mill, without previously referring the matter to
CARU. Indeed, on that day, Uruguay’s Ministry of Transport and Public Works gave Botnia the
right to use the riverbed, and authorized the construction of this port, and possibly a number of
53 channels, for Botnia’s exclusive use 130. Once again, Argentina learned of this project through the
Uruguayan media, and formally requested the Uruguayan Government to comply with the
obligation resulting from Article7 of the 1975 Statute. It did this through a note dated
27 June 2005, in other words before Uruguay issued the authorization, pointing out that a project of
this kind is subject to the consultation procedur e under the 1975Statute. The note also requested
Uruguay to appoint its delegation to CARU, so that the latter could resume its work as soon as
possible 131. The new government of President Vázquez had not appointed the new Uruguayan
delegates, thereby preventing CARU from operating. This new Argentine note also did not receive
a reply. As indicated above, Uruguay authorized the construction of the port eight days later.
2.64. The GTAN finally held its first meeti ng on 3August 2005. At this meeting, the
Argentine delegation repeated that its country did not wish to obstruct Uruguay’s economic
development, but that Argentina was concerned to protect the environment of a shared natural
resource and by the impact of the two pulp mills on the areas affected by it. The Argentine
delegation drew attention to the note from Mr.Bi elsa to Mr.Gargano of 5May2005, in which a
moratorium was called for, and pointed out that this had not received a reply. It presented a
detailed list of the information requested from Uruguay that was still lacking (these requests are set

out in Appendix II to the Minutes of the meeting), in particular regarding the reasons for the choice
of sites, why these were so close to the towns of Fray Bentos and Gualeguaychú and to each other,
and the grounds for choosing the “kraft” method of producing pulp.
2.65. The Uruguayan delegation pointed out that its country had turned down both the
54
request for a 180-day suspension and the call for relo cation of the mills contained in the note from
Mr.Bielsa to Mr.Gargano. It provided the Argentine delegation with documentation on the
relevant Uruguayan legislation and on the initial environmental authorization granted for CMB and
Botnia. On the siting of the mills, the Uruguaya n delegation replied that this was a sovereign
decision of Uruguay and that:
“the reason the plant was located at a certain place is alien to the Group and is not one
of its competences since, besides bei ng a d132sion taken prior to the present
government, the location of the plants is a fact” .
2.66. In the six months following its first meeting, the GTAN held 12 meetings. During this
period, the Parties exchanged documentation and raised various issues concerning the
environmental and cross-border impact of the m ills. It was not possible to bring the Parties’
positions together, even as regards the information considered necessary to produce an assessment.
2.67. Meanwhile, Botnia continued with th e construction of its Orion mill and started
building the port. Argentina twice formally re peated in CARU its demand that Uruguay should
fulfil its obligations under Articles7 to12 of the St atute, coupled with a request for work to be
suspended until CARU had taken a decision on the pl an to build the port. The President of the
Uruguayan delegation believed that the issue of c onstruction of the port did fall within CARU’s
remit, but that Uruguay would not suspend the construction work. On 15August 2005, the
Uruguayan delegation also forwarded to CARU the text of the resolution of 5July 2005
authorizing construction of the port, and on 13 Oc tober 2005 delivered some of the information on
this subject requested by Argentina. The Argen tine delegation believed that, in order to comply
with the procedure laid down by Chapter II of the 1975 Statute, in particular Ar133le 9, construction
55 work should be suspended to allow CARU to start dealing with the project . For its part, ENCE
also continued with the groundworks for the CMB mill.
2.68. In this context, and contrary to wh at had been planned, the GTAN was unable to
produce a joint report within the scheduled time-limit of 180 days, because of the major differences
outstanding between the two delegations. Each de legation produced a separate report at the end of
the Group’s work.
2.69. In its report of 3 February 2006, the Argentine Delegation to the GTAN reiterated that
Uruguay had breached its obligations under the 1975 St atute, noted the shortcomings and errors in
the present environmental impact assessments and criticized: th e sites chosen; the planned
production method; the studies of the impact of effluents on the water and biota, gas emissions and

solid waste; the lack of preventive and mit134ting measures; and the socio-economic impact of the
mills in the areas affected by the river .
2.70. In its report, the Uruguayan delegation st ated that it had sent the Argentine delegation
all the information that was available and asked for the remainder from the companies, which had
135
responded “according to the progress of their projects” ; this shows very clearly that Uruguay
itself did not have full information on the projects. The report took the view that progress had been
made on studying the impact of liquid emissions and that, as regards the studies of gaseous
emissions, changes had been made in order to asse ss their impact on the region of Gualeguaychú.
The Uruguayan delegation reiterated its positions on the substance of the dispute 136.
56 Section V
The failure of negotiations and the support of the Argentine Parliament
for referral to the International Court of Justice
2.71. At the end of 2005, given the Parti es’ conflicting positions on the extent of the
information required, the location of the mills and the technology they were to use, and on the fact
that the works were continuing and Uruguay was still granting authorizations for construction
without following the procedure laid down in the 1975 Statute, it became clear that the work of the
GTAN was moving towards deadlock.
2.72. On 14 December 2005, Argentina sent Uruguay a note in which it formally drew
attention to the existence of a dispute regarding the 1975 Statute, pointing out that Article 12 of the
Statute was applicable, that the procedure indi cated in ChapterXV was therefore open to the
Parties, and that the period of 180 days laid down by the Treaty for the Parties to reach a settlement
through direct negotiations had begun on 3 August 2005, the date of the GTAN’s first meeting 137.
2.73. On 26 December 2005, the Argentine Government repeated its serious concern at the
major tensions caused by the continuing construc tion of the mills and the port, which was creating
an unprecedented situation in the history of rela tions between Argentina and Uruguay. Argentina
once again called for the work to be suspended, with a view to reaching a swift and final settlement
138
of the dispute .
2.74. On 27 December 2005, Uruguay’s Minister for Foreign Affairs replied to Argentina’s
note of 14 December 2005, rejecting the Argentine protests and stating that Uruguay had provided
Argentina with all the information requested, show ing that the works were being carried out in
accordance with national and international standards. The note concluded that there was no dispute

57 between t139Parties and that the procedure laid down in the 1975Statute had therefore not been
opened .
2.75. By a note of 12 January 2006, Argentina rejected this last Uruguayan note, highlighting
the intrinsic contradiction between Uruguay’s argu ments and the denial of the existence of a
dispute. The140me note stressed the interpretations of the facts and the law given previously by
Argentina .
2.76. On 16January 2006, in response to th e previous note, Uruguay renewed the terms of
its note of 27 December 2006 141.
2.77. The period of 180days laid down for the activity of the GTAN expired on
142
3 February 2006, without the Parties reaching an agreement .
2.78. On 14 and 16 February 2006, the Argen tine Minister for Foreign Affairs explained the
state of the dispute to the Foreign Affairs Committees of the Chamber of Deputies and the
Senate 143. Both houses of the Argentine Congress adopted resolutions in which, given the failure
of the direct negotiations, they supported the G overnment’s decision to refer the matter to the
International Court of Justice.
58 Section VI
Further Argentine attempts to achieve a
bilateral settlement of the dispute
2.79. During February 2006, the Argentine Government proposed on several occasions that
the works should be suspended for a limited period to allow objective impact studies to be carried
out, with a view to settling the dispute. These proposals were not taken up by Uruguay.
2.80. It should be pointed out, in this context, that in his address to Congress of
1 March 2006, President Kirchner formally invited PresidentVázquez of Uruguay to continue to
seek a settlement of the dispute, on the basis of a 90-day suspension of construction work on the
mills while awaiting an independent environmental impact study 144.
2.81. The same day, the Argentine execu tive presented its report on the State of the
Nation2005, in which it confirmed Argentina’s po sition of steadfastly continuing to denounce
Uruguay’s breaches of the requirements under Articles 7 et seq.. of the 1975 Statute, and provided

a further refutation of Uruguay’s arguments. In the section on the environment, the 2005report
states as follows:
“As regards the controversy between Argentina and Uruguay over the plans to
construct two pulp mills on the left bank of the River Uruguay, and to avoid this being
aggravated by Uruguay’s unilateral authorization of the second mill ⎯ planned by the
Finnish company Botnia ⎯ at the start of May 2005, the Presidents of the two
countries agreed to set up a bilateral High-Level Technical Group ⎯ the GTAN ⎯
which would hold negotiations for 180 days in order to find a solution to the
controversy, under the supervision of the countries’ Ministries of Foreign Affairs. In
this Group, which began its activities on 3 August 2005, Argentina repeatedly asked
Uruguay for full and relevant information on the planned mills, in particular to explain
why this area was chosen as their location and to establish in an objective and reliable
way the cumulative cross-border impact th at might be produced on the ecosystem
59 associated with the River Uruguay. These requests were not met. On
30January 2006, after six months of nego tiations, the GTAN concluded its activities
without being able to reach a consensus.” 145
In the section on relations with Uruguay, the report continues:
“During 2005, there was a worsening of the dispute between Argentina and
Uruguay over the construction of pulp mills and associated facilities on the left bank
of the River Uruguay, a waterway shared between the two countries. The main reason
for this aggravation was the further unilate ral authorization granted by Uruguay, in
breach of the Statute of the River Uruguay, for a second mill, planned by the Finnish
company Metsä-Botnia, with twice the cap acity that had also been authorized
unilaterally at the end of 2003 for the Sp anish company ENCE. A third unilateral
authorization, likewise in breach of the St atute of the River Uruguay, was issued in
July, this time relating to the plan for a por t terminal associated with the second mill.
In all these cases, Uruguay ignored the repeated requests for information and
suspension of the projects from Argentina, both in the Administrative Commission of
the River Uruguay and at government level, aimed at allowing an objective and
reliable study to be made of the cumulativ e cross-border impact which the planned
works might produce on the ecosystem associat ed with the River Uruguay. With the
aim of trying to resolve this worsening of the dispute, the Presidents of the two
countries decided to set up a High-Level Group, which began work in August. When
this report was being prepared, in December 2005, the intransigence of the Uruguayan
delegation in the Group in terms of providi ng full and relevant information on the
projects, despite the repeated requests fro m its Argentine counterpart, was affecting
the prospects of bei146able to reach an agreement within the lifetime of this
negotiating body.”
Finally, the report summarized the situation within CARU as follows:
“A further dispute has arisen with in the Administrative Commission of the
River Uruguay (CARU) because of the unilateral authorization granted by Uruguay, in
breach of the prior notification and consulta tion procedure laid down by the Statute,
for a port terminal associated with one of the pulp mills planned on the left bank of

this cross-border waterway, likewise in breach of the Statute. This dispute has been
the subject of consideration by the two governments.” 147
2.82. On 11March 2006, at his meeting with President Kirchner in Santiago de Chile,
60 148
President Vázquez asked ENCE and Botnia to suspend construction of the mills , to allow a
bilateral agreement to be concluded. ENCE agre ed to suspend work for 90 days, but Botnia, after
initially doing the same, then refused to carry th149out and held just a 10-day “suspension”,
coinciding with the Easter holiday week in Uruguay . An agreement was in the process of being
finalized between the two countries to set up a pa nel of independent experts, which would produce
a comprehensive independent assessment of th e cumulative impact of the two mills on the
cross-border environment and propose th e measures to be adopted as a result 150. Because of
Botnia’s refusal, the meeting at presidential level that151s due to be held in Anchorena (Uruguay)
to formalize the agreement could not take place . On 6 April 2006, the Uruguayan Government
stated that “the direct negotiations with the neighbouring country are at an end” 15.
2.83. Also in April, reports appeared in the press of a plan by the Stora-Enso company to
153
construct a third pulp mill on one of the tributaries of the River Uruguay .
61 Section VII
Referral to the Court by Argentina and subsequent
aggravation of the dispute by Uruguay
2.84. On 4 May 2006, Argentina filed an application instituting these proceedings, and at the
same time requested the Court to indicate provi sional measures. On 13July 2006, the Court
delivered an Order regarding this request 154.
2.85.155 24 August 2006, Uruguay authorized the commissioning of the port terminal for the
Orion mill . Uruguay informed the Argentine delegation to CARU of this authorization on
4 September 2006 156. When this information was supplie d, the port terminal was already in
operation. Argentina took the view that this constituted a further breach of the requirement to
follow the procedure under Articles7 et seq. of the 1975Statute and also flagrantly contradicted
the Court’s recommendation to the Parties in paragr aph82 of its Order of 13July 2006 to refrain

in good faith the consultation and co-operation procedures provided for by the 1975 Statute 15.
2.86. On 12 September 2006, Uruguay authorized Botnia to extract and use the waters of the
River Uruguay for industrial purposes 158. On 17October 2006, the Uruguayan delegation merely
forwarded the text of this resolution to CARU for information, without complying with the
procedure under the Statute. Argentina took the vi ew that this constituted a further breach of the
requirement to follow the procedure under Articles7 et seq. of the 1975 Statute 159 also
contradicted the request made to the Parties by the Court in its Order of 13 July 2006 .
62 2.87. On 21 September, ENCE announced that it was abandoning construction of its CMB
mill at the planned site and proposed to relocate this plant, though without indicating where the
new site was planned. The Chairman of the company held his press conference at the offices of the
Presidency of the Eastern Republic of Uruguay. Explaining its decision, ENCE’s Chairman stated:
“We are relocating [the plant] because it is impossible from an industrial poin160
of view to construct two plants in Fray Bentos of the kind that are proposed.”
2.88. On 3October 2006, Argentina requested information from Uruguay concerning the
environmental impact assessment for the constr uction of a sulphur plant by the ISUSA company
near Agraciada (Department of Soriano), whose out put is intended for the Orion mill. Argentina
also asked Uruguay to refer this plan to CARU 161. Uruguay responded by stating that this request
was inadmissible 16.
Section VIII
Conclusions
2.89. From the facts set out above, it may be concluded that:
(a) Uruguay was fully aware of the fact that CARU had jurisdiction to deal with the CMB and
Orion projects;
(b) Uruguay deliberately decided not to subject the plans for the pulp mills and associated facilities
63
to the procedure provided for in Chapter II of the 1975 Statute;
(c) Following Uruguay’s authorization of the CMB project on 9October 2003, a dispute arose
between the Parties regarding CARU’s jurisd iction to deal with the CMB project, with
Argentina invoking that jurisdiction and Uruguay rejecting it;

associated with that plant, for the commissioning of the port, and for the extraction and use of
water from the River Uruguay by Botnia;

the provisions of the 1975 Statute. - 38 -
C HAPTER III
T HE APPLICABLE LAW ⎯ THE 1975 S TATUTE
3.1. The Statute of the RiverUruguay, which was concluded at Salto on 26February1975,
67
enshrines the rights and obligations concer ning the management and protection of the
RiverUruguay. The 1975Statute contains two clauses which refer to conventions and other
instruments (Art. 1 and 41 (a)).
3.2. The law applicable to this case will be set out below. In terms of its scope and
substance, that law has been framed in a par ticular way. To begin with, the 1975Statute ⎯ the
fundamental repository of the applicable law ⎯ is a legal instrument which was negotiated and
entered into in a particular context (Sec. I) reflec ting the special features of the legal régime of the
River Uruguay. In addition, the distinctive form the relevant law takes is apparent in the innovative
nature of the system of management, co-operati on and protection set in place by the 1975Statute
(Sec. II). Finally, the special nature of the applicable law is bound up with the need to interpret and
apply the 1975Statute in the light of the principles and rules of international law relating to
international watercourses and environmental protection (Sec. III).
Section I
The 1975 Statute is a legal instrument which was negotiated
and entered into in a particular context
3.3. The River Uruguay is subject to specific rules under the 1975 Stat163, which was signed
at Salto on 26 February 1975 and en tered into force on 18 September 1976 . The background to
the negotiation and conclusion of the 1975Statute was characterized by close links of friendship
and co-operation between Argentina and Uruguay. Th at spirit of close co-operation is reflected in
68 the many legal instruments adopted by both States. Those instruments include: the 1961 Treaty
concerning the Boundary Constituted by the River Uruguay 164, the 1969 Treaty of the River Plate
165 166
Basin , the 1971 Argentine-Uruguayan Declaration on Water Resources and the 1973 Treaty
concerning the Río de la Plata and the corresponding Maritime Boundary (hereinafter “the
1973 Treaty”) 16. Those legal instruments make it possibl e to understand the significance of and
the practice adopted in relation to the rights and obligations provided for by the 1975 Statute.
3.4. The 1975Statute has special links with the above legal instruments. While the
1961Treaty concerning the Boundary Constituted by the RiverUruguay (hereinafter “the
1961 Treaty”) provides the main basis (A), the fact remains that the 1975 Statute is the repository
of the legal values and principles relating to co-operation, management and protection where
international watercourses are concerned (B).

A. From the 1961 Treaty to the 1975 Statute
3.5. The 1975Statute was adopted in accordance with Article7 of the 1961 Treaty
concerning the Boundary Constituted by the River Uruguay. The168atute and the Treaty frame the
“community of interests . . . and common legal right” that governs the River Uruguay, and they
complement each other.
1. The 1961 Treaty symbolizing the co-operation between Uruguay and Argentina
69 3.6. The 1961 Treaty defines the boundary constituted by the RiverUruguay between
Argentina and Uruguay. Articles1 to 4 of th e Treaty define the RiverUruguay and assign the
islands and islets to each of the riparian Stat es. Taking that definition into account, the Treaty
169
further defines the juris170tions of the two States and sets out the obligations pertaining to
navigation of the river .
3.7. Although the purpose of the 1961 Treaty is to define the boundary constituted by an
international watercourse, it is also designed to lay down parameters governing the joint use and
management of the waters of the RiverUruguay. The 1961 Treaty goes beyond the principle of
“co-existence” and promotes uti singuli the principle of “co-operation”, further developing the
general principles of good neighbourliness (voisinage) between riparian States on the same
171
international watercourse .
3.8. That concern to establish close co-operation between Argentina and Uruguay and to take
account of the special features of the RiverUr uguay permeates both the spirit and tenor of the
1961 Treaty. For instance, the pr eamble to the 1961 Treaty declares that both States wish to take
into consideration the interests and aspirations of the other:
“The Government of the Argentine Republic and the Government of the Eastern
Republic of Uruguay, motivated by the common desire to tighten the close and
immutable bonds of affection and friendship which have always existed between their
respective peoples, have decided to settle once and for all the question of the
boundaries situated in the section of the River Uruguay which constitutes the frontier
between the two countries.
The two Governments, considering that, while they have identical rights over
70 the said section of the river, there are other factors which should be taken into
account... have decided to adopt as the boun dary a composite line which shall take

169Arts. 8-10 of the 1961 Treaty.
170Arts. 5 and 6 of the 1961 Treaty.
171
On the concept of neighbourliness, see the decision of 17 July 1986 on the Dispute concerning Filleting within
the Gulf of St Lawrence. In that decision the tribunal held that:
“while the concept of ‘voisinage’ is generally usedrefer to a situation of geographical vicinity, it is
used more specifically in juridical language to qualify situations of proximity which, in order to avoid the
creation of continuing fricti ons, call for continued collaboratithe benefit of the nationals or the
public service of two or more States whose activities interlock within a given geographical area. This is,
for instance, the case with the utilization of the same river basin, the prevention of pollution, the status of
frontier workers or certain customs areas.” ( Dispute concerning Filleting within the Gulf of St Lawrence
(France v. Canada), decision of 17 July 1986, International Law Reports, 1990, Vol. 82, pp. 590 et seq.) - 40 -
into account the aforesaid considerations and at the same time satisfy as fu172 as
possible the aspirations and interests of the two Contracting States.”
3.9. To confer legal substance on the “commun ity of interests” established in the preamble,
Article7 of the 1961 Treaty lays down the obligatio n to establish jointly a “régime for the use of
the river”. That régime was to include the following elements:
“(a) common standard regulations for the safety of navigation;
(b) a pilotage régime taking present practices into account;
(c) regulations governing the maintenance of dredging and buoying in accordance
with Article 6;
(d) reciprocal facilities for hydrographic surv eys and other studies connected with the
river;
(e) provisions for the conservation of living resources;
(f) provisions for preventing water pollution.”
3.10. In a landmark publication entitled El Estatuto del Río Uruguay , E. González Lapeyre
and Y. Flangini (hereinafter “Lapeyre and Flangini”) looked back at the circumstances surrounding
the adoption of the 1961 Treaty and give a deta iled description of its substance. They quote
JudgeJiménez de Aréchaga, who stressed the impo rtance of Article7 in the structure of the
1961Treaty as a provision designed to standardize the conduct of the two parties and secure the
legal régime governing the River Uruguay 173. It therefore appears that it was the clear intention of
the parties to the 1961 Treaty to establish a system of very close co-operation. That intention was
not destined to remain wishful thinking, since th e régime for the use of the River Uruguay was to
be adopted in the form of a statute, and, indeed, the 1975 Statute of the River Uruguay.
2. Historical background to the 1975 Statute
71
3.11. In their above-mentioned book, Lape yre and Flangini give an account of the
negotiations which led to the conclusion of the 1975Statute of the RiverUruguay 17. That book,
whose authors were involved in negotiating the Statute, has an important role to play in shedding
light on the circumstances and negotiations surroundi ng the Statute. Indeed, its role is confirmed
by the fact that CARU purchased several copies of the book in 1983 175.
3.12. The negotiations on the Statute of the RiverUruguay began in 1969, but, given the
climate of mutual trust which was established fro m the very beginning of the process, Argentina
172
Emphasis added. See Anns., Vol. II, Ann. 1.
173 “This, clearly, implies great progress, since it assu mes that uniform rules of this nature must, in
future, be laid down on the basis of agreement between the riparian States. This will be in the common
interest, since uniformity and certainty in relation to the legal régime applicable to the navigable section
of a river in its entirety are the prerequisite for ease and security of navigation. That uniformity can be
secured only on the basis of agreement between the ri parian States.” (E. G. Lapeyre and Y. Flangini,
ElEstatuto del Río Uruguay , Ediciones Jurídicas Amanlio M. Fe rnández, Montevideo, 1983, pp.71-72,
Anns., Vol. VII, Ann. 1.)

and Uruguay preferred to focus, first of all, on drafting the Treaty concerning the Río de la Plata
and the corresponding Maritime Boundary. That Treaty was adopted on 19 November 1973.
3.13. Following the adoption of the Treaty concerning the Río de la Plata, the negotiations
on the Statute of the River Uruguay were resumed. They lasted for two years, from 1973 to 1975.
Those negotiations too were characterized by the sa me spirit of mutual trust that characterized the
process of drafting the Treaty concerning the Río de la Plata. This was reinforced by the fact that
the same Argentine and Uruguayan negotiators were involved in both treaties. The negotiations
were concluded on 26February1975 when the Mi nisters for Foreign Affairs of the two States,
Juan Carlos Blanco and Alberto Vignes, signed the Statute of the River Uruguay at Salto.
3.14. The Statute of the RiverUruguay was approved by the Argentine Parliament by Law
No.21.413 of 9September1976 and by Uruguay’s Council of State by Law No.19.769 of
4May1976. As stated in the note accompanying the approval by Uruguay’s Council of State of
the Statute of the River Uruguay:
“I. This Statute was drawn up in accordance with the provisions of Article 7 of
the Treaty concerning the Boundary Constituted by the RiverUruguay, which was
72 ratified by the Republic on 19January1966 and is designed to establish the joint
mechanisms necessary for th e integral use of the RiverUruguay by the two
Contracting Parties, as well as to provide detailed clarification of certain judicial
issues that remained unresolved by the criteria laid down in the 1961 Treaty.
II. It is necessary to stress the infl uence which the solutions adopted in the
Treaty concerning the Río de la Plata and the corresponding Maritime Boundary of
19November1973 have had on this agreement. It could be said that this influence
has been exerted, in particular, at both a sp iritual and technical level. At a spiritual
level, because the negotiators worked in an atmosphere of marked cordiality which
had become firmly established during the cour se of negotiations on that Treaty, and at
a technical level, because they tried to transfer to the RiverUruguay, within the
framework established by the 1961 Treaty, the solutions envisaged in the treaty
provisions concern176 the Río de la Plata, adapting them to the special features of the
River Uruguay.”
3.15. The Argentine Government’s note acco mpanying the draft of Law No.21.413 also
emphasizes the relationship between the Statut e of the RiverUruguay and the 1961 Treaty.
According to that note:
“The 1961 Treaty set the boundaries between the two countries along the
section of the River Uruguay which constitutes the frontier. The Statute supplements
it, since it lays down the rules needed to regulate the different activities which take
place on the waters of that territorial river, taking account of its special features and
motivated, as stated in the preamble, by the fraternal spirit inspiring the Treaty
concerning the Río de la Plata and th e corresponding Maritime Boundary, signed at
Montevideo on 19 November 1973.” 177
3.16. The 1975 Statute lays down and defines strict obligations concerning the utilization and
protection of the River Uruguay. That agreement wa s negotiated over a short period, thanks to the
176
Diario de sesiónes del Consejo de Estado, 183 sesión ordinaria, 26 April 1976, p. 164, Anns., Vol. II, Ann. 3.
177
ADLA XXXVI-L, Ley 21.413, pp. 2802-2803, Anns., Vol. II, Ann. 4. - 42 -
mutual trust that had developed between the parti es. It demonstrates the lasting concern that had
existed (since 1961) to draw up a stringent and re liable system of rights and obligations pertaining
to co-operation on the River Uruguay.
73 B. The regional context for regulating the management of international watercourses and the
1975 Statute
3.17. The adoption of the 1975 Statute marked a further stage in the process of concluding a
number of regional and bilateral legal instruments concerning inte rnational watercourses. The
1969Treaty of the River Plate Basin, the 1971 Argentine-Uruguayan Declaration and the
1973Treaty concerning the Río de la Plata a nd the corresponding Maritime Boundary are clear
illustrations of the continuing desire of Argen tina and Uruguay to frame an international legal
régime covering the watercourses along which both are riparian States. Consequently, those
instruments facilitate a better understanding of th e special circumstances which surrounded the
adoption of the 1975 Statute.
1. The 1969 Treaty of the River Plate Basin
3.18. The Treaty of the River Plate Basin (hereinafter “the 1969 Treaty”) makes it easier to
understand the régime of the RiverUruguay since it represents one of the first attempts by the
States of the La Plata region (namely Argentina, Bolivia, Brazil, Paraguay and Uruguay) to create
joint institutions to manage water resour ces. A specific standing committee, the 178
“Intergovernmental Co-ordinating Committee of the countries of the River Plate Basin” was set
up to promote, co-ordinate and monitor the mu ltinational efforts to secure the integrated
development of the River Plate Basin. The Co mmittee’s mandate demonstrates the determination
of the States of the River Plate Basin to establis h institutional machinery for the joint management
of an international river.
74 3.19. The 1969 Treaty is also significant from a “territorial” perspective (ratione loci). In
point of fact, the States of the River Plate re gion decided to adopt a broad definition of the
RiverPlate including the “River Plate Basin and its zones of direct and measurable influence” 17.
The use of that terminology shows that the States of the River Plate region wished to bring a large
geographical area within the scope of the Treaty. It is useful, in this connection, to point out that
Article 1 of the Treaty of the River Plate Basin states that the Contracting Parties:
“shall promote, in the region of the basin... the formulation of such operating
arrangements and legal instruments as they may deem necessary to achieve the
following objectives: (a) facilitating and assisting navigation; (b) the rational
utilization of water resources, in particular by the regulation of watercourses and their
multipurpose and equitable development; (c) the conservation and development of
animal and plant life”.
178
In Feb.1967, the Ministers for Foreign Affairs of five above-mentioned States met in Buenos Aires and
adopted a Joint Declaration setting up an Intergovernmental Co-ordinating Committee. The second meeting of the
Ministers for Foreign Affairs of the riparian States of to de la Plata took place aSanta Cruz de la Sierra in
May1968. The meeting adopted the “San ta Cruz de la Sierra Act” and th e statute of the Intergovernmental
Co-ordinating Committee. On that point see: “Legal Problems posed by the non-navigational uses of international
watercourses: supplementary re port by the Secretary-General”, Yearbook of the International Law Commission (ILC) ,
1972, Vol. II (Part Two), p. 354.
179
Art. 1 of the 1969 Treaty of the River Plate Basin, Anns., Vol. II, Ann. 10. - 43 -
3.20. That choice of wording influenced the agreements concluded in 1973 and 1975
concerning the River Plate and the River Uruguay respectively.
3.21. The 1975Statute forms the continuati on of the 1969 Treaty of the River Plate which
underscores the commitment of the States of the River Plate region to promote the creation of joint
institutions to manage water resources. Furtherm ore, the 1969 Treaty reveals the attachment of
those States to the concept of the “basin” of an international watercourse.
2. The 1971 Argentine-Uruguayan Declaration on Water Resources
3.22. In 1971, shortly before the United Nations Stockholm Conference on the Human
Environment was convened in 1972, Argentina and Uruguay adopted a Declaration on Water
Resources. It was against the backdrop of that decl aration that the specific bilateral treaties for the
River Plate and the River Uruguay were signed in 1973 and 1975 respectively 18.
75 3.23. According to the preamble to the 1971 Declaration, the two States:
“have already begun to develop the River Uruguay, as prescribed in the time-table in
force for the Salto Grande Dam and in execu tion of the joint efforts to draw up the
RiverUruguay Statute, thus providing tangible evidence of the deep understanding
and close co-operation between the two Parties” 18.
3.24. In addition, Argentin a and Uruguay express their agreement with the fundamental
principles which must govern the utilization of in ternational watercourses. According to the two
States:
“The two Foreign Ministers express th eir agreement on the following basic
principles governing the régime for the utili zation of international rivers and their
tributaries:
1. The river waters shall be utilized in fair and reasonable manner.
2. States shall refrain from polluting intern ational rivers and tributaries in any
manner and shall conserve the ecological resources in the areas within their
respective jurisdictions.
3. If a State intends to utilize the waters of a river, it shall first transmit to the other
States concerned the plans for the works, the plan of operations and other data
which may be useful in determining the impact of works in the territories of those
States.
4. Within a reasonable period of time, the requested party must indicate whether
there are aspects of the plans or plan of operations which may cause it appreciable
damage. If so, it shall indicate the technical reasons and calculations
substantiating that claim and shall sugg est changes in the plans or plan of
operations designed to avoid such damage.

5. Disputes arising in that connection shall be submitted to a Joint Technical
Commission for settlement. In the even t that the technical experts should
disagree, they shall prepare a report expressing their views for consideration by the
Governments. The Governments shall e ndeavour to find a solution through the
diplomatic channel or by any other means they may agree upon, striving always to
reach an amicable and just solution.”
3.25. The 1971 Declaration demonstrates th e agreement between Argentina and Uruguay on
the principles governing the utilization of wate r resources, namely equitable and reasonable
76
utilization, the conservation of ecological resources, and the obligation to notify and consult with a
view to reaching prior agreement. Those principl es are the fundamental pillars of the system of
co-operation between Argentina and Uruguay concerning the River Uruguay.
3. The 1973 Treaty concerning the Río de la Plata
3.26. The 1973 Treaty concerning the Río de la Plata played an important role in the drafting
of the rules governing the RiverUruguay. The 1975Statute refers to that Treaty, stating that the
182
arrangements covering the two rivers are motivated by the same fraternal spirit . Certain
provisions of the 1973 Treaty were taken up in the 1975Statute. Furthermore, both those
instruments confer a significant role on the International Court of Justice in relation to safeguarding
the régime set in place.
3.27. Like the 1975Statute, the 1973 Treaty provides that if the parties are unable to reach
agreement on the implementation of a project likel y to cause substantial damage to the waters of
the river in question, one or other of the parties may refer the dispute to the International Court of
183
Justice . Furthermore, the Treaty concerning the Rí o de la Plata sets up an Administrative
Commission whose remit appears similar to th at of the Administrative Commission for the
River Uruguay 184.
3.28. It should, however, be pointed out that the 1975Statute of the RiverUruguay sets in
place a system of notification and consultation for the purposes of reaching prior agreement which
is more demanding than the arrangements set in pl ace by the 1973 Treaty. The latter provides that
this machinery is to apply only to projects which ma y affect the “navigation” or the “régime of the
river”. The 1975Statute applies that machinery not only to projects which may affect the
77 “navigation” or the “régime of the river” but also to projects which may affect “the quality of the
waters” of the RiverUruguay 18. Furthermore, the 1975Statute has extended the scope of the
obligations by laying down the requirement to protect the River Uruguay and the “areas affected by
it”.
182
According to the preamble of the 1975 Statute: “The G overnment of the Eastern Republic of Uruguay and the
Government of the Argentin e Republic, motivated by the fraternal spirit inspirinthe Treaty concerning the
Río de la Plata and the corresponding Maritime Boundary, signed at Montevideo on 19 November 1973”.
183
See Arts. 22 and 69 of the 1969 Treaty of the Río de la Plata, and Arts. 1 and 60 of the 1975 Statute.
184See Art. 60 of the 1973 Treaty of the Río de la Plata and Art. 56 of the 1975 Statute.
185In that connection, the Uruguayan negotiators Lapeyre and Flangini state that:
“Under the Statute of the RiverUruguay, Articl es 7 to 13 thereof, although inspired by the
above-mentioned articles [namely Arts. 17 to 22 of the 1973 Río de la Plata Treaty], arrive at a broader
solution. In point of fact, the consultation rels not only to significandamage which could harm
navigation or the régime of the river, but also that c ould affect the quality of its waters.” (E. G. Lapeyre
and Y. Flangini, op. cit., p. 75, Anns., Vol. VII, Ann. 1.) - 45 -
3.29. The 1969 Treaty of the River Plate Basin and the 1973 Treaty concerning the
RíodelaPlata and the corresponding Mariti me Boundary demonstrate the commitment of
Argentina and Uruguay to creating joint mechanisms to manage and protect water resources and
their intention to adopt a broad interpretation of the concept of “river”.
3.30. Furthermore, the 1971 Argentine-Urugua yan Declaration sets out the fundamental
principles governing the utilization and protection of a watercourse. All of these factors combine
to illustrate and clarify the particular regi onal context in which the 1975Statute of the
RiverUruguay was adopted and make it easier to comprehend the significance of the rights and
duties laid down by the Statute.
Section II
The 1975 Statute, a specific instrument governing
the legal régime of the River Uruguay
3.31. The 1975 Statute is made up of 63 articl es, divided into 17 chapters. The obligations
under the Statute form a unitary and interdependent whole. Obligations that are more procedural in
content, such as the obligations to notify and consult, make it possible to put into effect substantive
obligations, such as the principle of equitabl e and reasonable use and the requirement that
significant damage should be avoided. Those obliga tions are interlinked. In the context of the
78 work of the International Law Commission (ILC) on the law of the non-navigational uses of
international watercourses, Special Rapporteur S. C. McCaffrey pointed out in that connection that
186
“[t]he substantive and procedural principles . . . form an integrated whole” .
3.32. The special nature of the 1975 Statute is evident at three fundamental levels. Firstly, in
terms of the innovative system of joint “managem ent” which it introduces (A); secondly, in terms
of the exacting nature of the system of “co-operati on” which it establishes (B); and, thirdly, in
terms of the system of “protection” which derives from the scope of the obligations that the Statute
lays down (C). A common thread is apparent at those three fundamental levels: the concern to
prevent any unilateral utilization or exploitation of the River Uruguay.
A. An innovative legal régime for managing the river
3.33. The 1975 Statute advocates joint management of the River Uruguay. As a result of the
establishment of CARU and the obligations to prevent threats to navigation, the régime of the river
and the quality of its waters, Argentina and Ur uguay have established a very highly developed
system of co-operation in relation to the River Uruguay and the areas affected by it. Many aspects
of that system are innovative.
3.34. The system of joint management of the RiverUruguay comprises physical, territorial,
functional and institutional aspects. They illustrate the special nature of the legal régime for the
River Uruguay.

Third Report on the Non-navigational Uses of International Watercourses, by S. C. McCaffrey to the
International Law Commission, ILC Yearbook, 1987, Vol. II (First Part), A/CN.4/406, p. 23, para. 34. - 46 -
1. The physical aspect of joint management: the river
as a shared natural resource
3.35. In the 1975 Statute, Argentina and Uruguay expressed their intention of regarding the
79
River Uruguay as a shared natural resource.
3.36. That the River Uruguay is to be regarded as being a shared resource is evident from the
establishment of joint institutions to manage the river. Indeed, Article1 of the 1975Statute
stresses the need to establish the “joint m achinery necessary for the optimum and rational
utilization of the RiverUruguay” 187. CARU constitutes the forum par excellence permitting the
joint, shared and interdependent management of a shared natural resource such as the
River Uruguay 188. A system of interdependent management of that nature is vital if the aim and
purpose of the 1975Statute is to be secured, name ly the optimum and rational utilization of the
189
River Uruguay .
3.37. The shared nature of the River Uruguay is also apparent from the fact that obligations
are imposed on Argentina and Uruguay at an intern ational level. The 1975Statute is actually a
repository for the international obligations which are incumbent on the two States and precludes
either benefiting from any form of privilege to the de triment of the other. It is in the nature of a
shared natural resource that it must be subject to international rights and duties to ensure its rational
and optimum utilization by all the States concerned. That utilization is, of necessity, dependent on
compliance with the international obligations wh ich the 1975Statute lays down, as well as the
other international obligations to which Articles 1 and 41 (a) of the 1975 Statute refer. Pursuant to
Article 1, the optimum and rational utilization of the river must take place “in strict observance of
the rights and obligations arising from treaties and other international agreements in force for each
of the Parties”.
PurAsuoactle (a), the Parties are required to prescribe appropriate rules and
80 measures to protect and preserve the aquatic environment and prevent its pollution: “in accordance
with applicable international agreements and in keeping, where relevant, with the guidelines and
recommendations of international technical bodies.”
3.38. The “status” of the River Uruguay as a shar ed natural resource is, finally, reflected in
the fact that national use of the river for domes tic, sanitary, industrial and agricultural purposes is
subject to the obligations laid down in Articles 7 to 12, where utilization of that nature is significant
enough to affect the régime of the river or the quality of its waters 190. The right of each State to use
the river within its domestic jurisdiction is, ther efore, subject to obligations pertaining to
information, notification, consultation and prior ag reement, that is to say the strict co-operation
mechanism established under the 1975 Statute 19. That approach is confirmation that any unilateral
action which is incompatible with the 1975Stat ute and likely to alter the nature of the
River Uruguay and the areas affected by it must be rejected or excluded.

2. The territorial aspect of joint management: the concept
of the river and the areas affected by it
3.39. In its system of common management, the 1975 Statute included both the river 192 and
the areas affected by it. The scope of the Statut e is extensive. Pursuant to Article13, the
obligations laid down in Articles7 to 12 co ncerning referral to CARU, the exchange of
information, notification and consultation for the purpose of reaching prior agreement apply also to
all works which either Party plans to carry out on the River Uruguay “outside the section defined as
a river and in the areas affected by the two sections”, and thus on the Argentine-Brazilian section of
the RiverUruguay also. In practice, that means that Argentina has agreed to submit its projects
81 relating to the latter section to the procedure unde r Chapter II of the 1975 Statute, thereby enabling
CARU and Uruguay to comment on them. The obligations under Article13 apply to “all
developments which are likely to affect the ré gime of the river or the quality of its waters” 193.
Consequently, they cover any activity meeting those conditions in the areas covered by the Statute
and, in particular, those referred to in Article 13.
3.40. The significance of Article 13 was describ ed in the note of the Argentine Government
accompanying draft Law No. 21.413:
“In accordance with the aims of the Stat ute and the principles of international
law, the signatory States agree to apply th e same consultation procedure to any other
project with the characteristics which have been described or any utilization of the
waters which is significant enough to affect the régime of the river or the quality of its
waters that one of the parties plans to carry out on the RiverUruguay within its own
jurisdiction, but outside the section of river governed by the Statute or within the areas
194
affected by the two sections.”
3.41. That note further points out that:
“It would be difficult to achieve the aims which have been set, were the States,
individually, to act within the areas affected by the river without taking account of the
close reciprocal relationship that exists between all parts of a single system.
Therefore, and in order to be consistent w ith the stance adopted by the two countries,
the machinery is supplemented by extending the prior consultation procedure to works
which either of the riparian States undert akes within its jurisdiction in the areas
affected by the RiverUruguay which is the subject of the Statute, as well as in other
sections of that river not bordering on those areas.” 195
3.42. J. Barberis provided clarification of the scope and significance of Article 13 at the legal
and technical meetings of CARU that took pl ace on 17 and 18September1987. In relation to
Article 13:
82 “The same procedure should be follow ed when the implementation of the work
is likely to impede the flow of an aquifer in to the river, or if any party proposes to set
19According to Art.2 of the 1975Statute, the “river”eans “the section of the Ri verUruguay referred to in

up on a tributary of the River Uruguay the kind of industry that causes po196tion ⎯ a
tannery or a plant manufacturing certain chemicals, for example.”
3.43. The territorial scope (ratione loci) of the 1975 Statute must be assessed by reference to
both the term “river” and the term “areas affected”. Those areas must be protected in the light of
the concepts of the system formed by international watercourses and of their drainage basins. In its
report of 1980 on the law of the non-navigati onal uses of international watercourses, the
International Law Commission states that:
“[a]n international watercourse is not a pi pe carrying water through the territory of
two or more States. While its core is gene rally and rightly seen as the main stem of a
river traversing or forming an internationa l boundary, the international watercourse is
something more, for it forms part of what may best be described as a ‘system’; it
comprises components that embrace, or may embrace not only rivers but other units
such as tributaries, lakes, canals, glaciers 197 groundwater, constituting by virtue of
their physical relation a unitary whole.”
3.44. The Convention on the Law of the Non-navigational Uses of International
Watercourses, adopted by the United Nations General Assembly on 21May1997, defines
watercourses as: “a system of surface waters and groundwaters constituting by virtue of their
198
physical relationship a unitary whole and normally flowing into a common terminus” .
83 3.45. The term drainage basin more specifically clarifies the concept of area affected.
According to the International Law Association (ILA), a drainage basin must be construed as “a
geographical area extending over two or more States determined by the watershed limits of the
199
system of waters, including surface and underground waters, flowing into a common terminus” .
3.46. A report by the Parliamentary Assembly of the Council of Europe of 2004 stressed
that:
“The concept of hydrographical basin has gradually taken hold internationally
over the past fifty years. A water basin is an area of land from which all surface water
flows through a sequence of streams, rivers and, possibly, lakes into the sea at a single
river mouth, estuary or delta.

related to water resources and services through an integrated approach that considers a
basin as a single management and planning unit.” 200
3.47. Those factors dictate a broad interpretati on of the term “area affected” as contained in
the 1975Statute. The drainage basin ⎯ and, consequently, the area affected ⎯ encompasses not
only the surface and groundwater but also the land te rritory within a river’s watershed limits.
Professor Caflisch points out in this connection that:
“the term ‘drainage basin’ encompasses all of the aquatic elements located within a
84 watershed system . . . as well as ⎯ and this is a particularly important point ⎯ the
land that covers them. Consequently, this is a term which encompasses more than just
the aquatic element and has a territorial connotation, and even a regional or
201
sub-regional aspect.”
3.48. If Article13 is interpreted in the light of the concepts of the system of a watercourse
and of its drainage basin, then the scope of the 1975Statute must be deemed to be particularly
broad. That is significant for the purposes of assessing the rights and obligations which the
1975 Statute prescribes.
3. Joint management and how it operates: rational and
optimum utilization of the river
3.49. It is clear from Article 1 of the 1975 St atute that its purpose relates to the rational and
optimum utilization of the River Uruguay. Article 1 reads as follows:
“The parties agree on this Statute, in implementation of the provisions of
Article 7 of the Treaty concerning the Boundary Constituted by the River Uruguay, of
7 April 1961, in order to establis h the joint machinery necessary for the optimum and
rational utilization of the RiverUruguay , in strict observance of the rights and
obligations arising out of trea ties and other international ag reements in force for each
of the parties.” (Emphasis added.)
3.50. Respect for the rational and optimum u tilization of a river means that the riparian
States have to take account of the particular aspects of a watercourse and the possible consequences
that uses of the watercourse may have for one or the other of them. Those two adjectives imply
that the riparian States are under an obligation to secure, in their utilization of the watercourse, the
“optimal” benefits which are compatible with the need to protect the river. The aim of securing the
“rational” and “optimum” utilization of the Ri verUruguay may only be achieved jointly by the
85 co-riparians within “joint machinery”, notably CA RU; if this joint machinery is not used, the
1975 Statute will be deprived of its aim and object.
3.51. Rational utilization must be assessed and viewed objectively in the light of the
obligations which the 1975Statute lays down in re lation to information, notification, consultation
and prior agreement. Thus, rational utilizati on under the 1975Statute must be based on the
rigorous machinery for co-operation that has been set in place for that purpose. Only compliance

navigation”, Annuaire français du droit international, Vol. XLIII, 1997, p. 753. - 50 -
with the rights and obligations that are clearly determined and defined by the 1975Statute may
serve as an indicator that the River Uruguay is being used rationally and in good faith.
3.52. Optimum utilization, meanwhile, is ga uged in terms of the obligation incumbent on
each riparian State to prevent any threat to navigation, the régime of the river and the quality of the
waters. In that connection, any planned work s on and any use of the RiverUruguay must be
structured in such a way as to minimize damage to the river as a shared natural resource. If this is
not the case, the proposed measures in relation to th e river and the areas affected by it are likely to
deprive one of the riparian States of its right to op timum utilization, that is to say its right to enjoy
full use of the river. It follows that optimum utilization is utilization which takes account of any
objections a riparian State may raise when the measures are proposed. Optimum utilization implies
an assessment of that utilization in the light of the interests of both riparian States and not just one
of them, as well as in the light of the different uses of the river.
3.53. Each riparian State both has the right to use the waters of the river in an optimum and
rational manner and is under an obligation to prevent damage to the watercourse. If that
requirement is not respected, the other riparian Stat e is deprived of its right to attain optimum and
rational utilization of the waters of the river. In that context, in its commentary on the 1994 draft
Articles on the Non-navigational Uses of Intern ational Watercourses, the International Law
Commission took the view that:
86 “[a]ttaining optimal utilization and benefits does not mean achieving the ‘maximum’
use, the most technologically efficient use, or the most monetarily valuable use, much
less short-term gain at the cost of long-t erm loss. Nor does it imply that the State
capable of making the most efficient use of a watercourse ⎯ whether economically, in
terms of avoiding waste, or in any other sense ⎯ should have a superior claim to the
use thereof. Rather, it implies attain ing maximum possible benefits for all
watercourse States and achieving the greatest possible satisfacti202of all their needs,
while minimizing the detriment to, or unmet needs of, each.”
3.54. The principle of rational and optimum utilization, as the aim and object of the
1975Statute, remains central to the concept of “community of interests” as defined by the
International Court of Justice:
“[the] community of interests in a navigable river becomes the basis of a common
legal right, the essential features of which are the perfect equality of all riparian
States in the use of the whole course of the river and exclusion of any preferential
privilege of any one riparian State in relation to the others (Territorial Jurisdiction of
the International Commission of the River Oder, Judgment No.16, 1929, P.C.I.J.,
Series A, No. 23, p. 27).
Modern development of international law has strengthened this principle for
non-navigational uses of international wate rcourses as well, as evidenced by the
adoption of the Convention of 21 May 1997 on the Law of the Non-navigational Uses
203
of International Watercourses by the United Nations General Assembly.”

4. Joint management and its institutional form: the Administrative
Commission of the River Uruguay (CARU)
3.55. Chapter XIII of the Statute of the River Uruguay provides for the establishment of the
87
Administrative Commission of the RiverUruguay (CARU). CARU is an essential forum for
co-operation between the two riparian States.
3.56. CARU’s Statute was adopted, by common accord, on 18 September 1976, on the basis
of an exchange of diplomatic Notes, in accordan ce with Articl204 of the 1975Statute. Both 205
countries have the same number of representatives at CARU and it has legal personality .
According to Article2 of its Statute, CARU is an international organization which possesses the
206
legal personality required to enable it to carry out its specific mandate . The organization
exercises its functions on a permanent basis and has its own secretariat 20.
3.57. CARU’s decisions must be adopted with the consent of both delegations, according to
208
the principle “one delegation, one vote” . At least three delegates from each party must be
present for CARU to be in valid session 209. No matter how many of its delegates are actually
210
present, each delegation speaks through its president or substitute president .
3.58. CARU’s mandate is wide-ranging and it has extensive powers. It has the regulatory
powers provided for under Article 56 (a) of the 1975 Statute. It exercises its powers in relation to
safety of navigation on the river and use of th e main channel, conservation and preservation of
211
living resources and prevention of pollution of the river .
88 3.59. CARU has, in particular, executive powers in relation to navigation and works
envisaged by the parties 212, and it carries out controls and inspections 213. In that connection, it is
214
responsible for co-ordinating the joint conduct of scientific studies and research . Furthermore, it
co-ordinates activities for the prevention and prosecution of illegal acts, the adoption of joint plans,
215
handbooks and communication systems for search and rescue operations .
3.60. CARU also has responsibilities in relation to the administration and management of the
river. As a result of its position as a preferred point of contact between the two countries, CARU is
able rapidly to transmit to the States the communications, consulta tions, information and

notifications which they may send to each other in accordance with the Statute . Through the217
intermediary of CARU, the States regularly exchange information on fishing activities .
Argentina and Uruguay may decide to entrust othe r functions to CARU through an exchange of
218
notes or any other form of agreement .
3.61. CARU plays a vital role in maintainin g the integrity of the Statute and the proper
administration of the machinery for co-operation. That role was highlighted by the International
Court of Justice in its Order of 13July2006 in response to the request for the indication of
provisional measures. The Court in fact held that CARU is entrusted with “the proper
implementation of the rules contained in the 1975 Statute governing the management of the shared
river resource” and that the parties must “p rovide CARU with the necessary resources and
information essential to its operations”. The Court al so considered that in order to implement in
good faith the consultation and co-operation proced ures provided for by the 1975Statute, CARU
constitutes the envisaged forum in this regard 219.
89 B. A rigorous legal régime for co-operation designed to prevent threats to navigation, the
régime of the river and the quality of the waters
3.62. The 1975Statute is in many respects innovative in terms of the management and
protection of an international watercourse. Although concluded 22 years before the United Nations
General Assembly adopted the 1997 Convention on the Law of the Non-navigational Uses of
International Watercourses, the Statute provides fo r the establishment of a system of co-operation
which is far more rigorous than that laid down by the Convention.
3.63. Co-operation between the riparian States is based, in particular, on referral to CARU,
the exchange of information and the obligations to notify and consult with a view to reaching prior
agreement. Those obligations relate to any propo sed works or use which could have an impact on
the river and the areas affected by it.
1. Referral to CARU and the exchange of information
3.64. J. Barberis stressed the importance of having advance knowledge of a proposal when
he made the point that:
“for a State to be able to ascertain whet her any form of work or use could cause it
significant damage or in fact involves equitable and rational utilization of the waters, it
must have advance knowledge of the proposed use or work in question. The States
generally use, for that purpose, a procedure which involves notifying the other State of
the proposed work and how it will operate and providing any other information the
latter State needs to determine the impact of the proposed work on its territory.” 220

international, Centre d’étude et de recherche de droit intern ational et de relations intern ationales, The Hague, Martinus
Nijhoff, The Hague, 1991, p. 49. - 53 -
3.65. Under the 1975 Statute, the obligation to provide information initially takes the form of
90
compulsory referral to CARU. The substance of that obligation must be determined in the light of
its objective, which is to prevent threats to navigation, the régime of the river and the quality of the
waters. Consequently, the first subparagraph of Article 7 of the 1975 Statute provides that:
“If one Party plans to construct new ch annels, substantially modify or alter
existing ones or carry out any other works which are liable to affect navigation, the
régime of the river or the quality of its waters, it shall notify the Commission, which
shall determine on a preliminary basis and within a maximum period of 30 days
whether the plan might cause significant damage to the other Party.”
3.66. That provision lays down the obligation to refer to and inform CARU prior to any
measure regarding the authoriza tion or implementation of a project on the RiverUruguay.
Therefore, both referral to CARU and the exchange of information within CARU are obligations
incumbent on both States under the 1975Statute. Both of those obligations must be construed in
the light of their objective, which is to prevent thr eats to navigation, the régime of the river and the
quality of its waters. In 1981, when speaking at CA RU about the Garabi project, Mr. Lapeyre, the
President of Uruguay’s delegation to CARU, stated that:
“Article7 of the 1975Statute of the RiverUruguay is clear when it stipulates
that ‘[the State] shall notify the Commission . . .’. The Statute lays down a procedure
under which each country must notify the Administrative Commission and not each
other’s delegation. That may be considered to be a courtesy, a fraternal gesture of
goodwill. However, the procedure is clearly defined. It is for the Administrative
Commission of the River Uruguay to review wo rks which either of the parties wishes
221
to carry out.”
3.67. Once the party that wishes to carry out or authorize work that is significant enough to
91 affect navigation, the régime of the river or th e quality of its waters has referred the matter to
CARU, the latter has 30 days in which to give its opinion. If CARU decides that the project will
not result in significant damage, the party concerned may carry out or authorize the work.
3.68. CARU may decide that the project is likely to cause significant damage. Alternatively,
it may decide not to deliver an opinion. In both cases, the 1975Statute provides that the party
concern222is to notify and inform the other pa rty of the project through the intermediary of
CARU .
3.69. When CARU took the view that the Garabi project could cause significant damage,
Mr. Lapeyre, the President of Uruguay’s delegation to the Commission, stressed that:
“CARU’s decision of 18December1981, in accordance with the provisions of
Article 7 of the Statute of the River Uruguay, concerning the Garabi dam . . . must, in
our view, lead to the immediate suspension of the proposed work. In other words, the
work must not be undertaken, given that a bi-national body, which has jurisdiction and
includes the vote of the delegation of one of the countries that has proposed 223 works,
has adopted a resolution with which the latter must, of necessity, comply.”

explicitly to Article 7. Another example is the cargo terminal at Nueva Palmira . Compliance
with the obligation to notify under Article7 of th e Statute means that no project on or use of the
river may be authorized or carried out unless CARU has been seised and notified of the proposal.
94 2. The obligation to notify
3.71. The purpose of notifying proposed measures is to protect the riparian States of an
international watercourse from unilateral initiatives by the other States which could cause them
injury. It is the State which is contemplatinmeasures on an international watercourse that takes
the initiative to notify. Notification must be given by the State, even if the activities in question are
to be carried out by private entities. The commentary on the draft Articles on the Law of the

Non-navigational Uses of Inte rnational Watercourses, which resulted in the adoption of the
1997 United Nations Convention, makes it clear that a State planning a project on an international
watercourse must:
“notify other States that are likely to be aff ected by the activity that is planned. The
activities here include both those that are planned by the State itself and by private
entities. The requirement of notification is an indisp227able part of any system
designed to prevent or minimize transboundary harm.”
3.72. The 1975 Statute provides that if CARU decides that the project may cause significant
damage or if CARU does not reach a decision in th at regard, “the Party concerned shall notify the
other Party of the plan through the said Commission” 228. The content of that notification
comprises:
“the main aspects of the work and, where appropriate, how it is to be carried out and
shall include any other technical data that will enable the notified Party to assess the
probable impact of such works on navigation, the régime of the river or the quality of
its waters” 229.
3.73. If it is to be fully effective, the notifi cation must contain the information and data that
95
will enable the notified State to evaluate the propo sed project as accurately as possible, and, in
particular, the known but also the potential negativ e risks the project may involve for the notified
State. That is why the information which is co mmunicated must be as comprehensive as possible.
An environmental impact assessment (EIA) is an es sential instrument in that context, prov230ng an
analysis of all the possible environmental and social effects a project may have .
3.74. Carrying out an environmental impact assessment may not, of itself, fulfil all of the
conditions linked to the notificati on requirement. Notification must include: “the main aspects of
the work and, where appropriate, how it is to be carried out and shall include any other technical
231
data” .
3.75. Under Article 8 of the 1975 Statute:
“The notified Party shall have a peri od of 180 days in which to respond in
connection with the plan, starting from th e date on which its delegation to the
Commission receives the notification.”
During that period, the 1975 Statute lays down two major requirements: these consist in the
obligation to co-operate and to provide the notified State, at the latter’s request, with all the data
and information that is available and necessary to obtain an accurate assessment of the effects of
the proposed measures. In that connection, the 1975 Statute provides that:

22Art. 7 of the 1975 Statute.
229
Ibid.
230
See paras. 3.198-3.209 below.
23Art. 7 of the 1975 Statute. - 57 -
“Should the documentation referred to in article7 be incomplete, the notified
Party shall have 30 days in which to so inform, through the Commission, the Party
232
which plans to carry out the work.”
The Statute makes clear that:
96 “The period of 180 days mentioned above shall begin on the date on which the
delegation of the notified Party receives the full documentation.
This period may be extended at 233 discretion of the Commission if the
complexity of the plan so requires” .
Article8 requires the Parties to provide comprehe nsive information. The notified Party will be
able to state its position, with full knowledge of the facts, only provided it receives all of the
information and data needed to evaluate the impact of the planned measures.
3.76. Where a State has notified the other Party of its plans, there are three possible
scenarios: (1) the notified State does not raise objections; (2) the notified State does not respond
within the time-limit laid down; (3) the notifie d State concludes that the implementation of the
works may result in damage.
3.77. The first two possible scenarios are govern ed by Article9 of the 1975Statute, which
provides that: “If the notified Party raises no obj ections or does not respond within the period
established in article 8, the other Party may carry out or authorize the work planned .” Article 10
supplements Article9 by providing that: “The no tified Party shall have the right to inspect the
works being carried out in order to determine whether they conform to the plan submitted.”
3.78. The third possibility for which the 1975 Statute provides is that the notified State may
object to the planned measures. Under Article 11 of the Statute:
“Should the notified Party come to the conclusion that the execution of the work
97 or the programme of operations might signifi cantly impair navigation, the régime of
the river or the quality of its waters, it shall so notify the other Party, through the
Commission, within the period of 180 days established in article 8.”
And Article 11 further provides that:
“Such notification shall specify which aspects of the work or the programme of
operations might significantly impair navigation, the régime of the river or the quality
of its waters, the technical reasons on whic h this conclusion is based and the changes
suggested to the plan or programme of operations.”
3.79. Therefore, the 1975 Statute provides that if it objects to a project or a particular form of
utilization of the RiverUruguay, the notified State is to inform the other party through the
intermediary of the Commission within a period of 180 days, as of the date on which the notified
party has received comprehensive information. The notified State must state the reasons for its
23Ibid., Art. 8, second subpara.
233
Ibid., Art. 8, second and third subparas. - 58 -
objection to the plans of the other riparian Stat e by setting out “the aspects of the work or
programme of operations” which may significantly impair navigation, the régime of the river or the
quality of its waters, and the “technical reasons” on which this conclusion is based, as well as its
suggested “changes” to the plan. It follows that if a State raises objections to the implementation of
proposed work, the party concerned may not authorize or carry out that work on a unilateral basis.
The Statute lays down a requirement to consult with a view to reaching agreement between the
parties. If the two parties reach agreement, they may decide either to carry out or authorize the
work or that the party concerned is to refrain from carrying out the work.
3. The requirement to consult with a view to reaching prior
agreement with full knowledge of the facts
3.80. If the notified State raises an objection, Article 12 of the Statute provides that “[s]hould
the Parties fail to reach agreement within the 180 days following the notification referred to in
article 11 . . .” (emphasis added), the procedure for the settlement of disputes, in particular,
98 submission of the dispute to the International Court of Justice is to be followed 234.
3.81. The 1975Statute lays down requirements that are far more stringent than those
provided for in international law 23. If an objection is raised, then, in addition to referral to CARU
and the exchange of information and notification, there is a requirement to consult in order to reach
prior agreement with full knowledge of the facts. In meeting that obligation, the requirements of
the notified State must be taken into account in order to reach a solution on which both riparian
States can agree. The 1971 Argentine-Uruguayan Declaration on Water Resources had already
provided for a régime of that nature:
“In the event that the technical experts should disagree, they shall prepare a
report expressing their views for consideration by the Governments. The
Governments shall endeavour to find a solu tion through the diplomatic channel or by
any other means they may agree upon, striving always to reach an amicable and just
solution.” 236
The Joint Argentine-Uruguayan Declaration of 8 September 1976 ⎯ that is to say just a year after
the 1975 Statute was adopted ⎯ confirms the significance of the mechanism for prior information
and consultation under the Statute. In fact, in that Declaration, the two parties
“note with deep satisfaction that the Stat ute, which has now entered into force in
implementation of the provisions of the 1961 Treaty concerning the Boundary
Constituted by the RiverUruguay, is imbued with the same fraternal spirit that
resulted in the signing of the Treaty concerning the Río de la Plata and the
corresponding Maritime Boundary, as Artic le1 thereof reiterates the aim of
establishing the joint machinery necessary fo r the optimum and ra tional utilization of
the RiverUruguay, and, in a ddition, at the same time includes, in the bilateral legal
régime it establishes, the principle of pr ior agreement in relation to any work or
23Art. 60 of the 1975 Statute.
235
Reflected, inter alia, in the decision handed down in the case oUse of the Waters of Lac Lanoux and,
subsequently, in the principles codifi ed in Articles 11 to 19 of the 1997 United Nations Convention on the Law of the
Non-navigational Uses of International Watercourses.
23Paragraph 5 of the 1971 Argentine-Uruguayan Declaration on Water Resources, Anns., Vol. II, Ann. 11. - 59 -
99 activity that either of the Parties propo ses to carry out in t237shared section , or that
the Argentine Republic carries out in the upper section” .
3.82. The 1975Statute gives rise to obligations which are far more rigorous than Uruguay
sought to claim before the Court when it merely referred to the obligation to give “reasonable
238
place” to the interests of a riparian State . The form of words Uruguay used is based on the 239
judgment handed down in the case of the Use of the Waters of Lac Lanoux (France v. Spain) .
3.83. In the Lac Lanoux case, Spain and France were not linked by a treaty similar in content
to the 1975Statute. The tribunal noted at that ti me that the existence of a rule requiring prior
240
agreement as between France and Spain “can result only from a treaty” , and, in that case, no
such instrument existed. In contrast to th e legal instruments linking France and Spain, the
1975Statute lays down specific requirements regarding planned work on and uses of the
241
River Uruguay .
3.84. It must, therefore, be established that Uruguay is misconstruing the law applicable in
its dispute with Argentina, and it must be stressed that the 1975Statute provides the
decision-taking mechanism for any form of work or utilization that may significantly impair
navigation, the régime of the river or the quality of its waters. If an objection is raised, that
mechanism precludes any possibility of a unilateral decision.
3.85. The requirement to consult in order to reach prior agreement must be construed in the
100 light of the practice that has evolved in Latin America. That will make it possible to accentuate the
special nature of the machinery for consulta tion contained in the 1975Statute which operates
alongside the efforts of the riparian States to seek a “prior agreement with full knowledge of the
facts.”
3.86. An early example of this practice is provided by the Convention regarding the
Determination of the Legal Status of the Frontier between Brazil and Uruguay of
20 December 1933. Article XX of that Convention s tipulates that if the installation of plant for the
utilization of the waters may cause an appreciab le and permanent alte ration of a watercourse
running along or intersecting the frontier, the contracting State desirous of such utilization is no242o
carry out the work necessary for it until it has come to an agreement with the other State .
3.87. In their book El Estatuto del Río Uruguay , Lapeyre and Flangini comment on that
provision as follows:

(CR 2006/48, para. 12 (Sands)).

Argentina, that is undeniable” (CR 2006/47, para. 21 (Condorelli)).
24Convention regarding the Determination of the Legal Status of the Frontier between Brazil and Uruguay,
League of Nations, Treaty Series, Vol. CLXXXI, p. 80. - 60 -
“That rule, which applies to the River Uruguay because it constitutes a frontier
between the two States, provides an almost fully effective guarantee.
It actually involves more than just prio r consultation, since the consent of the
other State is required, and until that con sent is obtained, work on the project is
suspended.
That is to say that the mere fact that a particular time-limit following
consultation expires is not sufficient to permit the State which undertakes the
consultation to start work on the project; th e agreement and, therefore, the consent of
243
the other contracting party is a prerequisite.”
3.88. The Declaration of Montevideo adopted by the Seventh International Conference of
American States at its 5th plenary session on 24December1933 also sets out the requirement to
consult in order to reach prior agreement. It provides that:
101 “no State may, without the consent of the other riparian State, introduce into
watercourses of an international charact er, for the industrial or agricultural
exploitation of their waters, any alteration which may prove injurious to the margin of
244
the other interested State” .
3.89. The resolution of Asunción on the utiliza tion of international watercourses, adopted by
the Ministers for Foreign Affairs of the riparian States of the Río de la Plata at their fourth meeting,
which took place from 1 to 3 June 1971, again confir ms the need for prior consent and, indeed, in
relation to contiguous waters. It states that: “In regard to contiguous in ternational waters, which
fall simultaneously under the jurisdiction of two States, a prior bila245al agreement must be
concluded between the riparian States before those waters are utilized.”
3.90. At its 10th conference, held in Bu enos Aires in 1957, the Inter-American Bar
Association unanimously adopted a resolution on the utilization of international rivers. After
recalling the general principle according to which the States have the right to make use of the
waters of a system of international waters “provided such use does not affect adversely the equal
right of the States having under their jurisdiction other parts of the system” (para.(1)(1)), the
resolution sets out the rule requiring the prior agre ement of the other States concerned before there
can be any new form of utilization likely to jeopardize the waters of the basin:
“States having under their jurisdiction a pa rt of a system of international waters
are under a duty to refrain from making chang es in the existing régime that affect
adversely the advantageous use by one or more States having a part of the system
under their jurisdiction, except in accordance w ith (i) an agreement with the State or
102 246
States affected, or (ii) a decision of an international court or arbitral commission.”

24See paras.1 and 2 of resolution 25 “Declaration of Asunión on the use of international watercourses”. In
relation to successive international wate rcourses, paragraph 2 of the Declarati on provides that “each State may use the
waters in accordance with its needs, provided it does not cause significant damage to any other State of the river basin”.
24Resolution of the Inter-American Bar Association, ILC Yearbook 1974, op. cit., p. 208, para. 3. - 61 -
3.91. The rule concerning the prior approval of projects on an international watercourse has
therefore been overwhelmingly endorsed in Latin America, and the Statute of the RiverUruguay
continues that tradition.
247
3.92. Compared with global practice, this is a special feature which must be stressed . The
1997 United Nations Convention on the Law of th e Non-navigational Uses of International
Watercourses sets out the generally accepted inte rnational practice requiring respect for the
principles of notification and consultation in rela tion to proposed activities along an international
watercourse, but without going as far as the strict rule on agreement for which the Statute of the
River Uruguay provides.
3.93. According to the 1975Statute, if the parties are unable to reach agreement and the
consultations do not make it possible to reach agreement on the planned measures, those measures
must be subject to negotiations. T248negotiations must, in particular, be conducted in accordance
with the principle of good faith . As a last resort, the International Court of Justice may be seised
of the matter.
4. Reference to the International Court of Justice in the event of disagreement
3.94. The intervention of the International C ourt of Justice is an integral part of the
103 co-operation arrangements set in place by the 19 75Statute. By referring the matter to the
International Court of Justice, the parties can be assured that any dispute concerning proposed work
or a type of use that could pose a threat to the river and its ecosystem may form the subject of a
judicial decision to prevent the Statute’s integrity being undermined.
3.95. According to the note accompanying the approval of the Statute of the River Uruguay
by Uruguay’s Council of State:
“Articles7 to 13 lay down the proce dure to be followed should one of the
Contracting Parties be planning to carry out work substantial enough to affect
navigation, the régime of the river or th e quality of its waters. There must be
provision for the intervention of a Commission and a system of notification, control
and consultation of the other Party, with sufficient guarantees to ensure that, in the
absence of agreement between the Parties, the dispute settlement procedure under
Article12 will come into play, including the possibility of referring the matter to the
249
International Court of Justice (Article 60)” .
3.96. Reference to the International Court of Justice helps to achieve the objective of
preventing threats to the environment of the RiverUruguay. Argentina and Uruguay have
accorded the International Court of Justice a key role in their bilate ral relations in relation to the
use of a natural resource. That role is confirme d by the fact that reference to the International

For examples of other specific and st ringent régimes, see: Art. 5A of the 1995 Mekong Agreement; see also
Art. 6 on “Procedures for Notification, Prior Consultation and Agreement.” See Art. 4 of the Statute of the Senegal River
and Art. 10 of the Senegal River Water Charter.
248
For instance, Art.17(2) of the United Nations Conve ntion on the Law of the Non-navigational Uses of
International Watercourses provides that: “[t]he consultations and negotiations shall be conducted on the basis that each
State must in good faith pay reasonable regard to the rights and legitimate interests of the other State”.
24Diario de sesiónes del Consejo de Estado, op. cit., Anns., Vol. II, Ann. 3. - 62 -
Court of Justice is also provided for where proposed work or a type of use 250is carried out “outside
251
the section defined as a river and in the areas affected by the two sections” . The key role which
the International Court of Justice plays in the context of the 1975Statute was highlighted by the
President of the International Court of Justice as follows:
“The Statute of the RiverUruguay, whose provisions are at the centre of the
dispute, should further be of particular in terest to the International law Commission.
That Treaty, concluded, I remind you, in 1975, was considerably in advance of its time
in terms of watercourse law and environmental law. It actually was even ahead of the
Convention on the Law of the Non-naviga tional Uses of International Watercourse
adopted in 1997 following the pioneering work of the International Law Commission.
In addition to the usual notification and c onsultation mechanisms provided for in the
1997 Treaty and in most international watercourse treaties, the 1975 Statute addresses
indeed the issue of what happens when such mechanism fails, by giving jurisdiction to
104
the International Court of Justice. It es tablishes furthermore a252nitoring body and
has very detailed requirements as to information exchanges.”
5. Making forms of utilization that fall under the national jurisdiction
of a State subject to the co-operation régime
3.97. One of the important aspects of the co -operation régime under the 1975 Statute is that
it makes any form of national utilization that is “ liable to affect the régime of the river or the
quality of its waters” subject to the obligations to refer the matter to CARU, exchange information,
notify and consult with a view to reaching prior agreement.
3.98. Article 27 of the 1975 Statute is worded as follows:
“The right of each Party to use the waters of the river, within its jurisdiction, for
domestic, sanitary, industrial and agricu ltural purposes shall be exercised without
prejudice to the application of the procedure laid down in articles 7 to 12 when the use
is liable to affect the régime of the river or the quality of its waters.”
3.99. National uses of the River Uruguay are thus subject to the same principles as apply to
the works per se. Neither of the two States may unilatera lly decide whether a national use of the
waters is liable to affect navigation, the régime of the river or the quality of its waters. Article 29
provides that even planned uses “outside the secti on defined as a river and in the areas affected by
the two sections” (Article13 of the 1975Statute) and, therefore, on the upstream section of the
105 RiverUruguay at the frontier with Brazil, are subject to the obligations to exchange information,
notify and consult with a view to reaching prior agreement. According to Article29: “The
provisions of article 13 shall apply to all developments which are likely to affect the régime of the
river or the quality of its waters.”
3.100. The requirements pertaining to national use of the waters are a clear illustration of the
rigorous nature of the co-operation régime set in place by the 1975 Statute to prevent damage to the
régime of the river or the quality of its waters.

6. Practice followed in accordance with Chapter II of the 1975 Statute
3.101. The régime of the Statute of the RiverUruguay has been put to the test. It has not
remained a “dead letter”253s Uruguay may have s uggested in its request for the indication of
provisional measures . A variety of cases that have emerged in practice will be described below,
shedding light on the interpretation of this régime that requires the exchange of information,
notification and consultation in order to r each the prior agreement which the 1975Statute
prescribes.
(a) The case of the Garabi dam
3.102. Following the signature on 17 May 1980 of the Treaty between Argentina and Brazil
for the development of the shared water resources contained in the border reaches of the
RiverUruguay and its tributary, the Pepiri Guazú River (hereinafter “the 1980 Treaty”), the two
countries embarked on studies for the implementa tion of the Garabi dam project, on the upper
254
River Uruguay .
106 3.103. The proposal was discussed within CARU. The Uruguayan delegation first stated that
it had received incomplete documentation on the pr oposal and had not been consulted in a manner
compatible with the requirements laid down in Articles 7 to 13 of the 1975 Statute. At the meeting
of CARU on 13November1981, Mr.Lapeyre, the then President of Uruguay’s delegation, drew
attention to the obligation to notify CARU, a nd not the Uruguayan Government, of any works
being planned on the River Uruguay 255. At the November 1981 meeting, Argentina brought to the
attention of CARU the Estudio de factibilidad del proyecto Garabi . The Commission thus had a
maximum of 30days in which to decide whet her the proposal was likely to cause significant
damage to Uruguay.

255
The following is an extract from the Mr.Lapeyre’s speech to CARU. Part of that speech was cited at
para. 3.66 above. Mr. Lapeyre said:
“Art.7 of the Statute is clear when it provides ‘shall inform the Commission ...’ The fact that
Commodore CURA, Under-Secretary for International Re lations at the Ministry of Foreign Affairs,
travelled to Montevideo and had a conversation with Uruguay’s Under-Secretar y for Foreign Affairs,
informing him that the Treaty [Treaty for the development of the shared water resources contained in the
border reaches of the River Uruguay and its tributary, the Pepiri Guazú River] was to be signed, is of no
significance in relation to the effects of the Se of the RiverUruguay. The Statute lays down a
procedure under which each country must notify the Administrative Commission and not each other’s
delegation. That may be considered to be a courtesy, a fraternal gesture of goodwill. However, the
procedure is clearly defined. It is for the Administrative Commission of the RiverUruguay to review
works which either of the parties wishes to carry out.” - 64 -
3.104. On 18 December 1981, CARU decided that the planned works for the construction of
the Garabi dam on the northern section of the Rive r Uruguay could significantly affect navigation,
256
the régime of the river and the quality of its waters . Lapeyre expressed his deep satisfaction with
107 the decision which the Commission had taken. He described the decision as “the most transcendent
act in the institutional life of the Administrative Commission since its creation ⎯ the result of the
Commission’s interest, concern and sense of responsib ility to ensure that work to be carried out on
the River Uruguay does not run counter to the interests of the two countries”. He congratulated the
President on his chairmanship of the meeting and rejo iced in the fact of belonging to the basin of
the Río de la Plata, given the sense of unders tanding which Uruguay’s Argentine brothers on the
delegation of that great and dear country had displayed 25.
3.105. In 1983, the Uruguayan delegation e xpressed its concerns to CARU, suggesting that,
258
despite its decision, the Garabi dam might still be built . More specifically, on 29 July 1983, the
Uruguayan delegation stressed that in the light of CARU’s decision of 18December1981 “the
work must not be undertaken, given that a bi-national body, which has jurisdiction and includes the
vote of the delegation of one of the countries that has proposed the works, has adopted a resolution
with which the latter must, of necessity, comply” 25.
3.106. Furthermore, the Uruguayan delegation pointed out that, were a dispute to arise
108
between the two States, they should apply a prin ciple of international law whereby the States
concerned were required to ente r into negotiations. The Uruguayan delegation stressed that the
obligation to negotiate is “an obligation establis hed under customary international law to prevent
256CARU concludes that:
“I. The proposals for the Upper Uruguay, including the Garabi project, constitute in themselves an
integrated and interlinked system, a concept that doe s not apply to the section defined in the Treaty of
7 April 1961, between Argentina and Uruguay, on th e boundary constituted by the RiverUruguay. That
apparent difference between the two sections may im ply technical aspects that have not been assessed
with the requisite degree of certainty, and, in the final analysis, that could result in significant damage.
II. The requisite priority has not been accorded to navigation. It is possible to see a tendency to
refer to this vital element as if it were a secondary issue. A nd yet, river navigation is a fundamental
principle which is safeguarded by all of the tr eaties for multiple uses in relation to successive
international rivers. Two sectors have, for example, been identified, one downs tream of the Garabi, of
some 50 kilometres, and another of the same orde r of magnitude, downstream of San Pedro, where
navigation is impeded by shallows, a problem that can only be resolved by means of major and expensive
demolition and canalization works, which, in turn, could result in changes to the régime of the river.
Minimum operational levels and not normal operational levels are signi ficant in terms of navigational
effects, and the levels required to meet the premise of longitudinal navigation must be established beyond
dams at the minimum water level. In that connection, it is relevant to cite a comment taken from the
reference study: ‘the San Pedr o option would require a navigation channel downstream of questionable
effectiveness, since it affects the water levels and draughts upstream, as well as energy production’.
III. The study submitted has analysed many possible locations for the work to be implemented.
That situation leads us to assume that the possibility of significant damage must not be ignored.
IV. At the same time, there is deep concern thatthe project under consideration fails to include
provisions on maintaining water quality. In view of the foregoing, the Commission concludes, in brief,
that the implementation of the propos ed work planned for the Upper Ur uguay could result in significant
damage to navigation, the régime of the river and the quality of the waters.”
257Ibid., para. 7, pp. 520-521, Anns., Vol. III., Ann. 9.
258
Those concerns were based on the statements of Argentina’s Minister for Foreign Affairs, Aguirre Lanari, who
maintained, at a meeting of the Ministers for Foreign Affa irs of the La Plata region, that the Argentine-Brazilian
proposals for the upper Uruguay were continuing to move forwar d, as agreed, and that the work on the Garabi project
was suspended until Dec. 1983.
259This passage is taken from the above-mentioned speech by E. G. Lapeyre, para. 3.68. CARU, Minutes 6/83 of
29 July 1983, para. 3.2, pp. 397-398, Anns., Vol. III, Ann. 8. - 65 -
the unilateral implementation” of a project “befor e the States have exhausted all possible channels
for negotiation and the settlement of disputes” 260.
3.107. In 1984, in response to Uruguay’s re quest for information on the Garabi project,
Argentina stated that it had supplied Uruguay with the necessary information, being cognizant of
the principle of information and prior consultation. It pointed out that a decision had yet to be
taken on the project 261. At the fourth session in 1989, the Uruguayan delegation formally requested
notification of the Garabi project to set in motion the procedure laid down in A262cles 8 et seq. of
the 1975Statute and listed the docum ents Uruguay wished to consult . On 23March1990, the
Uruguayan delegation asked for an extension of the original 90-day time limit to study the
263
documents on the Garabi project . Tha264xtension was granted at the extraordinary meeting of
CARU which took place on 6 April 1990 .
3.108. In March 2006, the Uruguayan Ministry of Foreign Affairs sent a diplomatic Note to
the Argentine Embassy in Montevideo asking Ar gentina and Brazil to provide the official
documentation on the Garabi project pursuant to Article13 of the 1975Statute. In its Note,
Uruguay relied on a legal argument similar to that advanced by Argentina in the pulp mills case 265.
109 (b) The Santo Tomé-Sao Borja bridge
3.109. On 22August1989, the Argentin e and Brazilian Governments set up a joint
commission to consider issues relating to the construction and operation of an international railway
bridge on the RiverUruguay between the towns of Santo Tomé and Sao Borja. The commission
produced a document (pliego de licitación) setting out the parameters for the project’s
implementation. On 26 November 1993, the Arge ntine delegation communicated the information,
within C266, that it would shortly be producing the documentation concerning the pr267sed
bridge . The documentation was in fact provided on 15 December 1993 .
3.110. On 23 Decembe1 r993, the Urugua yan delegation furnished CARU with
Memorandum No.6 in which it stated that no new bridge on the RiverUruguay “should pose
268
obstacles to navigation on a greater scale than the Uruguayan bridge, the Pasos de los Libres ” .
On 28December1993, at the meeting of CA RU’s Sub-committee on Navigation and Works,
Ambassador Carasales, the President of the Arge ntine delegation, stated that he did not share
Uruguay’s view. According to Mr.Carasales, the pl anned bridge would affect neither the régime
nor the quality of the waters of the RiverUruguay. As regards navigation, Argentina maintained
that there was very little navigation on that sectio n of the river and that the bridge would not
constitute an obstacle to it.

3.111. Nonetheless, on 19May1995, Argentin a informed CARU that it had modified its
initial proposal in order to take account of the requirements set out by the Uruguayan delegation in
1993 26.
(c) The Casa Blanca canal
110 3.112. On 22July1994, Uruguay submitted to Argentina, within the framework of CARU,
the proposal for the Casa Blanca canal. The Arge ntine delegation stated that it was not in a
position to say wh270er or not the project would cause damage within the meaning of Article 7 of
the 1975 Statute . At the meeting, the two delegations set a deadline of 30 days, as provided for
by Article7 of the 1975Statute, without prejudice to the mandate given to CARU to carry out
271
studies on the project . On 7April1995, the experts concluded that “the calculations made
confirm the assumption that dredging operations for the Casa Blanca will not affect the beaches at
Banco Pelay” 272.
3.113. The Uruguayan delegation was of the view that, pursuant to Article8 of the Statute,
Argentina had a period of 180 days in which to respond to the proposal, starting from the date on
which its delegation to the Commission received the notification. Uruguay considered that, in the
absence of a response from Argentina and given th e results of the experts’ calculations, it was
273
authorized to start work on dredging the Casa Blanca canal . Uruguay took the view that the
period of 180 days, laid down in Article 8 of the 1975 Statute, had expired in April 1995 at the time
when the experts submitted their report, and stated that if the two States were unable to reach an
274
agreement, the procedure for settling disputes under the 1975 Statute could be invoked .
3.114. In 1997, CARU again took up the qu estion of dredging the canal. CARU’s minutes
of 7February1997 record that the Argentine dele gation stated that the study on the Casa Blanca
canal, which had been carried out by the province of Entre Ríos, had established that dredging the
275
canal would not have a negative impact on Argentina’s coastline . Argentina nevertheless made
the point that it reserved the right to inspect th e works being carried out in accordance with the
1975 Statute, and that should Uruguay modify the planned dredging, further consultation would be
required.
111 (d) The proposed Papelera Traspapel pulp mill
3.115. Between 1995 and 1996, the bodies of CA RU discussed the proposal to construct a
pulp mill at Fray Bentos, to be called Papelera Tr aspapel. The company wishing to set up in that
location was of Spanish origin.
3.116. In CARU’s minutes 6/95 of 20 July 1995, CARU’s Sub-committee on Water Quality
and Pollution Control noted that it had receive d resolution 407/95, adopted by the Deliberative
269

Council of Concepción del Uruguay (Honorable Concejo Deliberante de Concepción
del Uruguay). In that resolution, the Council expressed its concern at the possibility of a pulp mill
being established 276. Consequently, the Sub-committee ask ed DINAMA to provide CARU with
277
the project documentation as soon as possible .
3.117. CARU’s minutes record the receipt of a memorandum drawn up by Mr.Amorín, an
engineer and official of DINAMA. The memo randum contained information on the steps the
company had taken in relation to DINAMA up until 15August1995 278. The memorandum
provides information on the manufacturing tec hniques the proposed factory would use, and
concludes that it would have to be subject to ve ry strict conditions in relation to environmental
impact, in accordance with the applicable Uruguayan legislation and the rules laid down in
279
CARU’s Digest on the Uses of the River Uruguay .
112 3.118. In 1996, Mr.Marchessi, a member of the Argentine delegation, asked CARU’s
Technical Secretariat to gather together all of the relevant documentation concerning the proposed
Traspapel pulp mill dating back as far as 1995 280. At the plenary meeting of 23 August 1996, in his
capacity as President of the Uruguayan delegatio n to CARU, Mr.Lapeyre suggested that the
proposal to construct a pulp mill at Fray Bentos “could evolve into a matter of concern that it
would be difficult to resolve within the Administrative Commission of the River Uruguay.”
And he added that:
“the Commission’s main responsibility ⎯ or, at least, one of its main
responsibilities ⎯ is to preserve the quality of the waters of the RiverUruguay and,
clearly, when we are speaking of an industrial plant which could affect the quality of
the waters, it is necessary to take a very cautious approach to management of the issue
and to comply with the requirements laid down in Articles 7 to 13 of the Statute of the
River Uruguay.”
Mr. Lapeyre also stressed on that occasion that th e request for information was “in certain respects
281
a formal procedure” . In his view, the provision of the information requested constituted one of
the prerequisites if the consultation required under the 1975 Statute was to be effective and actually
take place. The company concerned finally decided not to construct the Traspapel pulp mill.
(e) Port M’Bopicuá
3.119. In 2001 and 2002, CARU considered th e proposal for Port M’Bopicuá, situated close
to the Uruguayan town of Fray Bentos. Pursuant to Article 7 of the Statute of the River Uruguay,
Uruguay had notified CARU of the project. On 12April2001, CARU’s Sub-commit282 on
113 Navigation, Works and Erosion adopted a resolution on the proposal . In it, the Sub-committee’s

technical experts considered that there was no objection to implementing the project. The
2001 resolution specifically refers to Article 7 of the 1975 Statute.
3.120. CARU discussed the company Thenon S. A.’s proposal for Port M’Bopicuá at its
meeting of 8July2002. The President of the Ar gentine delegation stressed the need to obtain all
the information needed to enable CARU to undertake a proper review of the project, as well as the
need to comply with all international commitm ents concerning water qua lity and pollution. The
President of the Uruguayan delegation (at the time, the President of CARU) agreed with
Argentina’s request. Consequently, CARU decided to gather together all the necessary information
to enable the relevant subcommittee to evalua te it and submit its report to the full Commission 283.
The steps CARU took in relation to the Port M’Bopicuá project illustrate what must be done before
the Commission takes a decision.
(f) Cargo terminal at Nueva Palmira
3.121. At the meeting of 17February2006, the President of CARU stated that the
Uruguayan delegation had provided information c oncerning the proposed construction of a cargo
terminal at Nueva Palmira. The Uruguayan delega tion gave CARU that information in order to
comply with the requirements under Articles 7 et seq. of the 1975 Statute 28.
3.122. When that project was being discussed , the Argentine delegation pointed out that it
was not connected to the proposed construction of pulp mills which are the subject of a dispute
between Argentina and Uruguay. Furthermore, th e Argentine delegation pointed out that, on the
basis of Article 7, CARU must determine, within 30 days, whether the plan proposed by one party
114 might cause significant damage to the other party. With that in mind, the Argentine delegation
asked that the Commission should be provided, as rapidly as possible, with all the relevant
information concerning that project.
C. A legal régime for overall protection
3.123. The legal régime applicable to th e RiverUruguay is a legal régime for overall
protection which sets out specific obligations in rela tion to navigation, the protection of the régime
285
of the river and the protection of the quality of the waters and the river’s ecosystem . A failure to
observe any of those obligations is a failure to observe the principle of the rational and optimum
utilization of the river.
1. Ensuring that the River Uruguay remains navigable
3.124. Pursuant to Article3 of the 1975Statut e: “[t]he Parties shall afford each other the
necessary assistance so as to pr ovide the best possible facilities and safety for navigation”. As

28CARU, Minutes 2/06 of 17 Feb. 2006, para. 5.2, Anns., Vol. III, Ann. 6.
28For an excessively restrictive view of the protection régime, see the statement by Mr. Condorelli, according to
which: “the pulp mills we are discussing are not liable to affect navigation or the régime of the river: nor does Argentina
so claim. The Statute is thus solely relevant with a view to the ‘significant damage’ that ⎯ according to the opposing
Party ⎯ these mills risk causing it by impairing the ‘quality’ of the river waters.” (CR 47/2006, para. 8 (Condorelli).) - 69 -
Lapeyre and Flangini have said: 286t]his rule is programmatic in s ubstance; it conveys a priority
obligation that must be observed” .
3.125 Article4 of the 1975Statute establish es that the Parties are to agree jointly on
“provisions governing the safety on the river and the use of the main channel.” That obligation
115 establishes the principle of common rules for navigation. That is one of the innovative elements in
287
the 1975 Statute as compared with the 1973 Río de la Plata Treaty .
3.126. Dredging, buoying and conservation in th e sections of the main channel are subject to
specific rules highlighted by the régime of co-operation on the River Uruguay. Under Article 5:
“[t]he Commission shall assign to the Parties, following joint planning, such tasks of
dredging, buoying and conservation in the sections of the main channel as it may
periodically determine on the basis of the u se of the channel and the availability of
288
technical facilities” .
Argentina and Uruguay have made provision for notification of the projects referred to in Article 5.
In point of fact, under Article 6:
“For the purposes indicated in article 5, each Party shall, within its jurisdiction,
permit the competent services of the other Pa rty to carry out th e respective tasks,
following notification through the Commission.”
3.127. The different uses of an internationa l watercourse, including navigation, are closely
interlinked. In his first report to the Inte rnational Law Commission, S. Schwebel, Special
Rapporteur on the non-navigational uses of intern ational watercourses (and, later, a judge) stated
that:
“The interrelationships between na vigational and non-navigational uses of
watercourses are so many that, on any waterc ourse where navigation is practised or is
to be instituted, navigational requirements and effects and the requirements and effects
of other water projects cannot be separated by the engineers and administrators
289
entrusted with development of the watercourse . . .”
116 3.128. The 1997 United Nations Convention me ntions the relationship between navigation
and the other uses of a watercourse, stating that, in some instances, “other uses affect navigation or
are affected by navigation” 290.
28E. G. Lapeyre and Y. Flangini, op. cit., p. 73.
287
According to the 1973 Río de la Plata Treaty, each ripa rian State “which builds or has built a channel shall
likewise draw up the corresponding regula tions”. The Administrative Commissi on is responsible for sharing out
responsibilities for regulation in the different sections of cha nnels in the waters of common interest. Arts. 12 and 13 of

2. Protecting the régime of the River Uruguay
3.129. According to the Hydrographic Dictionary , the régime of a river refers to all of the
elements whose seasonal variations characterize the situation at a given place” 291. A river’s natural
292
régime is determined by the size of the river, the climate, the geology and the vegetation . The
Statute of the River Uruguay requires that the régime of its waters should not be affected by works
or any other form of utilization.
3.130. Scientific writers have stressed the relationship between changes in the river régime
and its impact on the ecosystem. For example: “flow régime is of central importance in sustaining
the ecological integrity of flowing water systems . . . Modification of flow has cascading effects on
the ecological integrity of rivers.” 293
3.131. A resolution of the Conference of the Parties to the Convention on Wetlands of
International Importance especially as Waterfowl Ha bitat (hereinafter “the Ramsar Convention”),
to which both Argentina and Uruguay are parties, stresses the links between protecting wetlands
and the natural régime of the water. The reso lution containing the “Guidelines for integrating
117 wetland conservation and wise use into river basin management” was adopted in 1999 and explains
that:
“Wetland ecosystems depend on the mainte nance of the natural water régimes
such as flows, quantity and quality, temp erature and timing to maintain their
biodiversity, functions and values. The natural flow régime can be considered the
most important variable that regulates the ecological integrity of riverine wetland
ecosystems. The construction of structures that prevent the flow of water, and of
channels that carry water out of the floodplain faster than would occur naturally, result
in the degradation of natural wetlands and eventual loss of the services they provide.
In response to these concerns, a number of countries have introduced legislation and
guidelines to ensure adequate allocation of water to maintain natural wetland
ecosystems.” 294
The resolution adopted by the States party to the Ramsar Convention demonstrates that the
ecosystems of wetlands ⎯ such as those bordering on rivers ⎯ may be affected by changes to the
natural water régime. That illustrates how important it is to maintain the natural régime of a river
like the River Uruguay.
3. Protecting the quality of the waters of the River Uruguay
3.132. The 1975Statute attaches great impor tance to protecting the river and preventing
pollution. Article40 provides a broad definition of this. It means: “the direct or indirect
introduction by man into the aquatic environment of substances or energy which have harmful

118 effects”. That definiti295encompasses all sources of pollution, as well as both deliberate and
accidental pollution .
3.133. Protection of the quality of the wate rs of the RiverUruguay is assured both by the
States’ adoption of national measures and by CARU , which is responsible for adopting rules and
standards in that area. Under Article 41, the parties undertake “[t]o protect and preserve the aquatic
environment and, in particular, to prevent its pollution , by prescribing appropriate rules and
measures . . .” (emphasis added). Article 41 provides further that the rules and measures adopted
by the Parties are to be prescribed “in accordance with applicable international agreements and in
keeping, where relevant, with the guidelines a nd recommendations of international technical
bodies” 296. The parties have adopted, for that purpose, the Digesto sobre el uso y aprovechamiento
del Río Uruguay (hereinafter the “Digest”). Section E3, Title 2, Chapter 4, of the Digest lays down
water quality standards 297.
3.134. The 1975Statute requires the States to adopt national legislation which must be in
accordance with their commitments and the standa rds laid down by appropriate institutions.
Argentina and Uruguay are under an obligation not to reduce or disregard in their respective legal
systems “[t]he technical requirements in force fo r preventing water pollution, and the severity of
119 the penalties established for violations” 298. Furthermore, both parties are under an obligation to
“inform one another of any rules which they plan to prescribe with regard to water pollution in
order to establish equivalent rules in their respective legal systems” 299.
3.135. It is important to stress that, pursuant to Article 42 of the Statute: “Each Party shall
be liable to the other for damage inflicted as a r esult of pollution caused by its own activities or by
those carried out in its territory by individuals or legal entities.”
3.136. That provision relates both to State activities that cause pollution and to the activities
of private operators within the territory of the Stat e. It thus establishes that each State is liable to
the other in respect of the resultant pollution.
3.137. Moreover, Argentina and Uruguay have pr ovided in the 1975 Statute that they are to
“agree on rules governing fishing act300ties in the river with regard to the conservation and
preservation of living resources ”. That provision demonstrates the concern of the riparian States
to protect the river and its living resources a nd confirms the commitment of Argentina and
Uruguay to establish a legal régime to prevent pollution in the waters of the River Uruguay.
29The wording of Art.40 of the 1975Statute follows in the tradition of the workof the International Law
Association at its 1966 meeting in Helsinki, as well as of the documents produced by the 1972 United Nations
Conference on the Environment in Stockholm.

4. Protecting the ecosystem of the River Uruguay
3.138. The 1975Statute provides for protection of the ecosystem. That protection is based
on Articles 35 and 36.
120 3.139. The Convention on Biological Divers ity, to which both Argentina and Uruguay are
parties, defines the ecosystem as “a dynamic complex of plant, animal and micro-organism
301
communities and their non-living environment interacting as a functional unit” .
3.140. In its commentary on the draft Articles on the Non-navigational Uses of International
Watercourses, the International Law Commission explained that the term ecosystem means an:
“ecological unit consisting of living and non-living components that are
interdependent and function as a community. ‘In ecosystems, everything depends on
everything else and nothing is really wasted.’ Thus, ‘[a]n external impact affecting one
component of an ecosystem causes reactions among other components and may
disturb the equilibrium of the entire ecosystem’.” 302
3.141. As S.McCaffrey has pointed out: “‘ ecosystems’ of an international watercourse
should be understood to include not only flora and fauna in and immediately adjacent to a
watercourse, but also the natural features within its catchment that have an influence on, or whose
degradation could influence, the watercourse” 303.
3.142. The 1997 United Nations Convention embraces that concept by providing for the
304
protection of watercourse ecosystems . The regional agreements on international watercourses
also advocate a similar form of management 30.
3.143. The 1975Statute is clearly innovative in that it stipulates, well before the United
121
Nations Convention was adopted, that Argentina and Uruguay are to co-ordinate “through the
Commission, the necessary measures to avoid any cha nge in the ecological balance and to control
pests and other harmful factors in the river and the areas affected by it” 306.

Sustainable Development of Lake Victoria.

3.144. Furthermore, the 1975 Statute includes in the joint régime for managing the river the
management of the soil and woodland and the use of groundwater and the water of the tributaries
of the River Uruguay, providing that
“[t]he Parties undertake to adopt the necessary measures to ensure that the
management of the soil and woodland and th e use of groundwater and the waters of
the tributaries of the river do not cause changes which may significantly impair the
307
régime of the river or the quality of its waters” .
3.145. Those obligations, for which the 1975 Statute provides, demonstrate the desire of both
Argentina and Uruguay to advocate and prom ote an overall protection régime for the
River Uruguay and its ecosystem.
5. Instruments designed to secure the protection of the River Uruguay
3.146. Various instruments adopted within CARU or between CARU and Argentine and
Uruguayan local authorities have enabled the two Stat es to implement their obligations with regard
to the protection of the River Uruguay. Those inst ruments demonstrate the desire of the two States
to develop further the obligations contained in the 1975 Statute.
(a) Digest on the uses of the waters of the River Uruguay and the setting of standards
122 3.147. CARU has set standards relating to the water quality and the conservation and
preservation of the living resources of the RiverUruguay. Those standards are contained in
308
Sections E3 and E4 of the Digest . This instrument constitutes the direct expression of the
intention of the parties and the way in which they construe the provisions of the 1975 Statute.
3.148. According to the diplomatic Notes of 1990 concerning the adoption of SectionE3,
that section was drawn up pursuant to Article 7 (f) of the 1961 boundary Treaty and Articles 35, 36,
41 to 45 and 56 (a) (4) of the 1975 Statute, and it “determin es the basic and substantive principles
for preve309ng pollution of the waters of the ri ver and laying down the quality standards for its
waters” . Furthermore, Uruguay recognizes that it is bound by the “Regulations on pollution”
which the Commission has drawn up 31.
3.149. In its diplomatic Note to Uruguay of 1995 concerning SectionE4, Argentina states
that this chapter was drawn up to implement Articles37, 38 and 39 of the Statute and that the
regulations
“demonstrate once again the desire of both our countries to bring matters of common
interest positively to fruition and lay down the rules permitting the conservation,
utilization and preservation of the living resources in the shared section of the
30Ibid., Art. 35.
30For water quality standards, see para. 3.151 below.

Note of 27 Nov. 1990, Anns., Vol. II, Ann. 14.
31Ibid. - 74 -
RiverUruguay, thereby constituting an hist oric point of reference which has few
311
equivalents in today’s world” .
3.150. The aim and purpose of the Digest is to protect and preserve the aquatic environment
and its ecological balance, to guarantee all le gitimate uses of the waters, taking account of
long-term requirements and, particularly, those pe rtaining to human consumption. The Digest is
123 further designed to prevent all new forms of pollution and eliminate them where the 312ues and
standards adopted in respect of legitimate uses of the river have not been observed .
3.151. The Digest establishes the responsibilities of the States and those of CARU in relation
to preventing pollution. The States issue authorizations and lay down restrictions or prohibitions
concerning the uses of the waters, and notify CA RU if those authorizations, restrictions or
313
prohibitions relate to risks to human health . The States jointly assess the quality of the waters of
the river in accordance with the standards laid dow n in Title 2, Chapter 4 of Section E3. Those
standards relate, in particular, to substances which could pollute the waters of the river and affect
human health.
3.152. The Digest lays down the liability of the States for damage caused as a result of
pollution of the river which is consequent on the activities of a State or natural or legal persons
falling within its jurisdiction 31. The Digest refers to Articles7 to 12 of the 1975Statute
concerning the procedure laid down for the construc tion of works and for the uses of the waters of
the river. Title 2, Chapter 5, contains the ru les on the conditions relating to effluents in the
River Uruguay and Title 2, Chapter 6, lays down th e conditions for discharges and spillage into the
river. Title 3 of the Digest is devoted to research into pollution. CARU may encourage and
co-ordinate research into pollution that is conducted by the parties, either individually or jointly.
Moreover, if CARU considers it relevant, it ma y conduct, of its own initiative, the studies and
research necessary for it to carry out its mandate in relation to pollution 31.
(b) The 2002 Environmental Protection Plan for the River Uruguay
124 3.153. The Regional Agreement on the adop tion of an “Environmental Protection Plan”
(hereinafter “the Regional Agreement”) and the Environmental Protection Plan for the
River Uruguay (hereinafter “the 2002 Plan”), conc luded at Paysandú on 29 October 2002 between
CARU and 15 Argentine and Uruguayan local authorities, specify the obligations set out by the
1975Statute. They provide a collective, participative and collaborative framework for
co-operation and co-ordination to protect the River Uruguay “for future generations” 316.
3.154. The 2002 Plan covers the protection of the river and the aquatic environment and
contains obligations to take measures that will make it possible to take better account of matters of
common interest, such as tourism. The Plan view s tourism as one of the growth activities in the
region. The preamble to the Regional Agreement re fers to “the desire to work for sustainable
development of the RiverUruguay ecosystem.. ., taking account of the natural resources of the

river, its islands, banks and alluvial areas”. Th e 2002 Plan is a further stage in the process set
under way by the 1975Statute, the Digest and the Co-operation Convention of 18August2001,
signed between the local authorities and CARU.
3.155. The 2002 Regional Agreement is broad in scope. It applies to the River Uruguay, the
groundwaters, the aquatic and land-based ecosystems which interact with the river and the drainage
basin of the RiverUruguay 317. Furthermore, the Regional Agreement draws on the principles of
environmental protection that are recognized by Argentina and Uruguay and set out in the
RioDeclaration, adopted at the 1992 United Nations Conference on Environment and
Development 31.
3.156. The commitments which the parties have entered into are set out in Article4. They
include further developing the exchange of in formation and co-operation both between the local
125 authorities and between the local authorities and CARU. The local authorities undertake to take
such independent measures as they may deem nece ssary, within their respective jurisdiction, to
ensure that “technical projects with potentially harmful effects on the ecosystem are subject to prior
authorization, with due regard to the general regulations and the necessary special requirements”.
3.157. In operational terms, the aim of the Re gional Agreement is to integrate action by the
local authorities with CARU’s activities, by ensuring that public and private bodies in both
countries play an active role. With that in mind, seven “strategic subject areas” and an operational
structure comprising several bodies have been put in place 319.
Section III
The 1975 Statute must be interpreted and applied in the light of the international
instruments and the relevant principles and rules of international law
3.158. The negotiators of the 1975Statute pl aced it at the heart of the international legal
system. They did this first of all by means of the referral clauses contained in Articles 1 and 41 (a).
Under those Articles, the States are required to observe “the rights and obligations arising from
treaties and other international agreements in fo rce for each of the Parties”, and to protect the
aquatic environment and prevent pollution “by prescribing appropriate . . . measures in accordance
with applicable international agreements and in keeping, where relevant, with the guidelines and
recommendations of international technical bodies”.
3.159. From that perspective, since the C ourt has jurisdiction in relation to disputes
126 concerning the “interpretation or application of the... Statute”, the question whether one of the
two States has observed the rights and obligations ar ising from other agreements is an issue which
may arise in relation to the interpretation or application of the Statute.
Since the 1975 Statute itself
provides that it is to be implemented taking account of those rules also, it follows that the latter
must be numbered among the rights and obligations under the Statute.
31Art.1 of the Regional Agreement on the Adoption of an “Environmental Protection Plan for the
River Uruguay”, Anns., Vol. II, Ann. 9.
318
Ibid., Art. 3.
31Ibid., Art. 5. - 76 -
320
3.160. In point of fact, the above-mentioned referral clauses make it possible to
incorporate and apply the rights and obligations arising from other treaties and international
agreements in the relations between Argentin a and Uruguay established under the 1975Statute.
Consequently, they must, of necessity, be taken into consideration in order to clarify, organize and
define the meaning, substance and scope of the rights and obligations laid down by the
1975 Statute, as well as to supplement those rights and obligations.
3.161. Furthermore, the interpretation of th e 1975 Statute gives way to general international
law and, in particular, the “principles governing international fluvial law in general”. In the case of
the Territorial Jurisdiction of the International Commission of the River Oder, the parties asked the
Permanent Court of International Justice (PCIJ) for an interpretation of Article 331 of the Treaty of
Versailles in order to establish the territorial lim its of the Commission’s internationalization and
administration régime. The six governments (Czechoslovakia, Denmark, France, Germany,
Sweden and the United Kingdom) and Poland did no t agree on how certain terms in Article331
should be construed 321. The Permanent Court of International Justice held, in that case, that where
“the grammatical analysis of a text” does not lead to definite results, “there are many other methods
of interpretation, in particular , reference is properly had to the principles underlying the matter to
322
127 which the text refers” . On that occasion, the 323rt referred specifically to “the principles
governing international fluvial law in general” .
3.162. Generally speaking, it should be not ed that it is necessary to adopt a systematic
interpretation of the 1975Statute that takes acc ount of the relevant legal context and of “any
relevant rules of international la w applicable in the relations betw een the parties”, as specifically
laid down in Article 31 (3) (c) of the Vienna Convention on the Law of Treaties. That requirement
was underlined by the International Court of Justice when it held that “an . . . instrument has to be
interpreted and applied within the framework of the entire legal system prevailing at the time of the
interpretation” 324. The 1975Statute must be interpreted in an evolutive manne r, so that proper
325
account may be taken of new environmental norms . The content of the rights 326 obligations
which the 1975 Statute lays down is not static but “by definition, evolutionary” .
320As regards the scope of referral clauses generally, see M. Forteau, “Les renvois inter-conventionnels”,
Annuaire français de droit international, 2003, pp. 71-104.
321The Court was asked to determine whether “that part of the two tributaries which is above the German frontier
may be regarded as providing more than one State with acces s to the sea, in the sense of Article331 of the Treaty of
Versailles” ( Territorial Jurisdiction of the Inter national Commission of the River Ode(Czechoslovakia, Denmark,

A. The relevant principles of the law on international watercourses applicable to this dispute
1. The principle of the equitable and reasonable utilization
of an international watercourse
3.163. The principle of the optimum and rational utilization of the River Uruguay is linked,
in particular, to the principle of equitable and r easonable utilization. The latter principle has been
incorporated into Article5 of the Conventio n on the Law of the Non-navigational Uses of
International Watercourses, which was adopted by the General Assembly of the United Nations on
21 May 1977.
128 3.164. In the case concerning the Gabčíkovo-Nagymaros Project (Hungary/Slovakia) , the
International Court of Justice held that:
“Re-establishment of the joint régime will also reflect in an optimal way the
concept of common utilization of shared wa ter resources for the achievement of the
several objectives mentioned in the Treat y, in concordance with Article 5,
paragraph2, of the Convention on th e Law of the Non-navigational Uses of
Watercourses, according to which:
‘Watercourse States shall participate in the use, development and
protection of an international waterc ourse in an equitable and reasonable
manner. Such participation includes both the right to utilize the
watercourse and the duty to cooperate in the development and protection
thereof, as provided in the present Convention.’ (General Assembly
327
doc. A/51/869 of 11 April 1997.)”
3.165. Article 5 of the 1997 United Nations Convention indicates that the right to utilize an
international watercourse is coupled with the duty to protect it. Special Rapporteur Schwebel made
clear in that connection that:
“the element of ‘protection’ defined to cover, above all, water quality, the
environment, security, water-related disease and conservation, calls for measures or
works that may limit to some degree the u ses that otherwise might be made of the
waters by one or more system States. Th e well-being of the peoples dependent on the
waters of the system, not to mention protec tion of th328arine environment, may give
certain measures of protection overriding priority.”
3.166. Although each riparian State has the ri ght to use the waters of a river for several
purposes, none of those uses enjoys inherent priority. The 1997 United Nations Convention
codifies that rule in providing that: “In the absence of agreement or custom to the contrary, no use
129 of an international watercourse enjoys inherent priority over other uses.” In its commentary on the
draft Article, the International Law Commission stat ed that: “[t]he reference to an ‘inherent
priority’ likewise indicates that nothing in the nature of a particular type or category of use gives it
presumptive or intrinsic priority over other uses” 329.
32Gabčíkovo-Nagymaros Project (Hungary/Slovakia), op. cit., p. 80, para. 147.

Third Report on the Law of the Non-navigational Uses of International Watercourses, by Special Rapporteur
Schwebel, ILC Yearbook, Vol. II (First part) 1982, A/CN.4/SER.A/1982/Add.1, p. 104.
329
Draft Articles on the Non-navigational Uses of International Watercourses, op. cit., p. 110. - 78 -
3.167. The 1975Statute reflects that approach . Domestic, sanitary, industrial, 330icultural
and navigational uses are mentioned, but none enjoys priority over the others .
3.168. In the final analysis, interpreting the principle of optimum and rational utilization of
the RiverUruguay in the light of the principle of equitable and reasonable utilization implies that
Argentina and Uruguay must both take account of elements specific to the River Uruguay, as well
as of the uses the two riparian States actually ma ke or propose to make of the river. Among the
elements to be taken into account, special im portance attaches to preserving the quality of the
waters of the river. The 1975 Statute and the pr actice Argentina and Uruguay have adopted within
CARU clearly confirm that interpretation.
2. The principle of using an international watercourse
in a way that avoids damage
3.169. In addition to that of equitable and reasonable utilization, the principle of optimum
and rational utilization draws on the principl e of avoiding damaging use of territory 331. In the
context of the 1975Statute, that principle is put into effect through the rules relating to the
assessment of a project and those providing for the uses of the waters of the River Uruguay. If one
party is planning works or a form of utilization of the waters that is significant enough to affect
130
navigation, the régime of the river or the quality of its waters, it must notify CARU. CARU then
determines whether the works or utilization in qu estion may cause “significant damage to the other
Party” 33. That principle is spelt out in the 1975Statute in the form of the obligation to avoid
causing significant damage.
3.170. Articles 7 and 11 of the 1975 Statute c onfer on CARU and the notified party the right
to determine whether a project or form of utilizati on of the waters of the River Uruguay is liable to
cause significant damage. In practice, CARU was called upon to give its opinion on the Garabi
333
project and took the view that the project could cause significant damage . Furthermore, in
relation to the Canal Casa Blanca project, the Ur uguayan delegation took the view that, pursuant to
Article8 of the Statute, Argentina had a peri od of 180 days to state its view on the damaging
334
effects of the proposed project .
3.171. The 1975Statute also requires the States to adopt legislation to ensure that “the
management of the soil and woodland and the use of groundwater and the waters of the tributaries
of the river do not cause changes which may significantly impair the régime of the river or the
335
quality of its waters” . In that context, the principle of avoiding the harmful use of an
international watercourse forms part of an ecosy stemic approach which includes management of
the soil and woodland and the use of groundwater and the waters of the tributaries of the river.
33See Arts. 3 and 27 of the 1975 Statute, in particular.
33On the customary nature of this principle, see: Corfu Channel (United Kingdom v. Albania), Judgment, I.C.J.
Reports 1949, p.22; Legality of the Threat or Use of Nuclear Weapons, Advisory Opinion, I.C.J. Reports 1996, p.242,
para. 29, and the Gabčíkovo-Nagymaros Project (Hungary/Slovakia), op. cit., p. 41, para. 53.

33See paras. 3.112-3.114 above.
33Art. 35 of the 1975 Statute (emphasis added). - 79 -
3.172. The principle of avoiding damaging the use of a watercourse also falls within the
general context of preventing pollution. Accordi ng to Article 42 of the 1975 Statute “[e]ach Party
shall be liable to the other for damage inflicted as a result of pollution caused by its own activities
or by those carried out in its territory by individuals or legal entities” (emphasis added).
131 3. The principle of co-operation and reliance on domestic law
3.173. During the procedure in relation to the request for the indication of provisional
measures, Uruguay on several occasions referred to its domestic law to demonstrate that it was
complying with the requirements for the protection of the environment and prevention of
pollution 336. However, Uruguay must also observe its international commitments.
3.174. The Permanent Court of International Ju stice drew attention to that principle in the
case of the Free Zones of Upper Savoy and the District of Gex , taking the view that the principle
that the sovereignty of France is to be respect ed applies “in so far as it is not limited by her
international obligations . . .” 337. Similarly, in the Lac Lanoux case, the Arbitral Tribunal held that
“[t]erritorial sovereignty plays the part of a338 esumption. It must bend before all international
obligations, whatever their origin...” Article27 of the 1975Statute makes that principle
explicit339.
3.175. Uruguayan law cannot, in any event, replace international oblig ations entered into
under the 1975Statute. That Statute is not based on some kind of principle of “subsidiarity” but
squarely on the principle of the need to respect the international machinery for co-operation which
the Statute has set in place. The domestic legislations of the two States must be compliant with it.
B. The principles of international environmental law applicable to this dispute
132
3.176. Various principles and concepts provi de a clearer understanding of the scope of the
1975Statute in relation to environmental protection. A systematic and evolutive interpretation of
the 1975Statute requires that these principles be ta ken into account, so that the pro340ions of the
Statute are interpreted and applied in the context of the current legal
system .

339
Art. 27 of the 1975 Statute reads as follows: “[t]he right of each Party to use the waters of the river, within its
jurisdiction, for domestic, sanitary, industrial and agricral purposes shall be exercised without prejudice to the
application of the procedure laid down in Articles 7 to 12 when the use is liable to affect the régime of the river or the
quality of its waters”.
340
This link between the 1975Statute and the relevant principles of intern ational law on the environment was
noted by the Argentine delegation to the High-Level Group (G TAN) from the beginning of those direct negotiations (see
Chap.II above). Indeed, at the Group’s second meeting, on 19Aug.2005, the delegation tabled a document listing the
environmental rules which it considered material to the dispute (Anns., Vol. IV, Ann. 1, pp. 5 and 6).
The link was further noted by Argentina when it confirmed to Uruguay that a dispute existed in accordance with
Art. 60 of the Statute. In point of fact, in its note SER EE 154 of 26 Dec. 2005, Argentina described the prior notification
and consultation procedures under the 1975 Statute as being - 80 -
1. The principle of sustainable development
3.177. Argentina and Uruguay are linked by respect for the principle of sustainable
development when the two States undertake activities on the River Uruguay.
3.178. The right to economic development cannot be asserted at the expense of obligations to
protect the environment. Those obligations are es sential if each State is to achieve its right to
develop. The effect of the principle of sust ainable development is to make environmental
obligations an integral part of the right of each State to economic development.
341
133 3.179. As the conceptual model underpi nning international law on the environment , the
concept of sustainable development requires an in tegrated approach to the objectives of economic
development and environmental protection. That principle was solemnly declared by Principles 3
and 4 of the 1992 Rio Declaration on Environment and Development.
3.180. One of the key elements of the principle of sustainable development is that meeting
the developmental needs of curre nt generations must not jeopardize the well-being of future
generations: “The right to development must be fulfilled s342s to equitably meet developmental
and environmental needs of present and future generations.” Principle 4 meanwhile sets out the
principle of integration: “In order to achieve sustainable development, environmental protection
shall constitute an integral part of the development process.”
3.181. The International Court of Justice has stressed that: “This need to reconcile economic
development with protection of the environment is aptly expressed in the concept of sustainable
development.” 343
3.182. The 2005 arbitral decision in the Iron Rhine Railway case also stressed the need to
integrate the appropriate environmental meas ures into projects and activities relating to
environmental development 344. The implication of that integration is that “[e]nvironmental law and
the law on development stand not as alternatives but as mutually reinforcing concepts” 345.
“firmly rooted in [the] general inte rnational law concerning the protecti on of the environment, as one of
the elements necessary to make effective the principle according to which a State must guarantee that the
activities carried out within its jurisdiction or under its control do not cause damage to the environment of
other States. Both the mechanism and the principle onwhich it is based... are directly or indirectly
embodied in the very many international instrument s in whose preparation that country [Uruguay] and
Argentina participated ⎯ in particular, the 1972 Declaration on the Human Environment and the
1992Declaration on Envir onment and Development ⎯ and in bilateral instruments such as the
1971 Argentine-Uruguayan Declaration on Water Resources.” (Anns., Vol. II, Ann. 28.)

34Ibid., para. 59. - 81 -
134 3.183. The Institute of International Law highl ighted the human dimension of that principle
when it stated that “[t]he effective realization of the right to live in a healthy environment should be
integrated into the objectives of sustainable development” 34.
3.184. Public participation is one of the cr ucial elements of the principle of sustainable
development. Seve347 legal instruments lay down that principle, as well as the principle of access
to information . In order to integrate environmental and developmental issues as well as possible,
it is necessary to improve the decision-making process in relation to the use of the natural resources
of the River Uruguay. These issues cannot be viewed in isolation.
3.185 Furthermore, there is also a social aspect to sustainable development, and the
Johannesburg Summit drew attention to its importance:
“we assume a collective responsibility to a dvance and strengthen the interdependent
and mutually reinforcing pillars of sustainable development ⎯ economic
development, social development and environmental protection ⎯ at the local,
348
national, regional and global levels” .
3.186. Proposed uses of natural resources are having an increasing impact on the ecosystems
that are necessary for the well-being of the population and the development of their socio-economic
activities 34. The decision-making process must take account of socio-economic considerations and
135
environmental issues in order to secure developm ent that is economically efficient, socially
equitable and responsible, and environmentally sound” 350.
3.187. It is quite clear that planned proj ects on the RiverUruguay must respect all of the
elements of sustainable development. None may take priority over any other.
2. The principle of prevention
3.188. The often irreversible character of damage to the environment means that such
damage must be prevented 35. That was the concern of the negotiators of the 1975Statute.
Articles1 and 41 (a) of the 1975Statute stipulate that the obligation to prevent pollution must be
observed, taking account of the rights and obligati ons arising from treaties and other international
agreements in force for each of the Parti es, and in keeping with the guidelines and
recommendations of international technical bodies.
346
According to Art.3 of the Strasbourg resolution of the In stitute of International Law of 4Sept.1997: “[t]he
effective realization of the right to live in a healthy environment s hould be integrated into the objectives of sustainable
development”.

3.189. Set out in Principle21 of the Stockhol m Declaration, and adopted by Principle 2 of
the Rio Declaration, the obligation to prevent pollution is based on the sovereign right of the States
to exploit their own resources and requires them to ensure that “activities w ithin their jurisdiction
352
or control do not cause damage to 353 environment of other States” . That obligation derives
from general international law .
136 3.190. Attention has been drawn to the obligation to prevent pollution, inter alia by the
International Court of Justice in its Advisory Opinion in the case of the Legality of the Threat or
Use of Nuclear Weapons and by the Arbitral Tribunal which handed down the decision in the Iron
Rhine Railway case. The obligation to prevent pollution ap plies to any damage or any threat of
damage and harm to the environment.
3.191. The Digest specifies certain aspects of this obligation, as contained in the
1975Statute. According to Article1 of Section E3 of the Digest, which deals with “Preventing
pollution”, its aim is to prevent pollution in accordance with Articles56 (a) and 4 of the
1975Statute. According to Article2 of Section E3, preventing pollution of the RiverUruguay is
governed by the 1975 Statute, the applicable intern ational conventions, the Digest and the national
legislations. The Digest provides definitions whic h are significant in the context of the dispute
concerning the pulp mills. Prevention is defined as “all methods which make it possible to prevent
pollution of the waters”. Pollution means “the direct or indirect introduction, by man, into the
aquatic environment of substances or energy w ith harmful effects”, and industrial pollution is
caused by “solid, liquid or gaseous emissions which derive from industrial activity, including
mining and energy production” 354. Furthermore, the Digest defines the concept of “harmful
effects” as “any change to the quality of the wate rs which prevents or im pedes any legitimate use
of the waters, produces harmful effects or damage to the living resources, risks to human health, a
threat to water-based activities, including fishing, or the curtailment of recreational activities” 355.
3.192. The water quality standards are define d as “[t]he numeric concentration values or
137
specific recommendations on water quality criteria, which are drawn up as a permanent point of
reference to permit legitimate uses of the waters and the adoption of measures to prevent
pollution” 35.
3.193. A State carrying out or authorizing projects on the River Uruguay must ensure that the
obligation to prevent pollution is observed.
3. The precautionary principle
3.194. There is no longer any doubt about the inherent link between the precautionary
principle and the principle of sustainable develo pment, and academic writers have stressed the
352Principle 2 of the Rio Declaration on Environment and Development.

357
relevance of this . Furthermore, the Convention on Pe rsistent Organic Pollutants and the
Convention on Biological Diversity both att ach importance to the precautionary principle 358. As a
result of the referral clause contained in Articles1 and 41 (a) of the 1975Statute, those
international instruments must be taken into consideration.
3.195. The precautionary principle implies that: “Where there are threats of serious or
irreversible damage, lack of full scientific certain ty shall not be used as a reason for postponing
359
cost-effective measures to prevent environmental degradation.”
3.196. The precautionary principle thus places a further obligation on Argentina and
Uruguay, in addition to the obligations to exer cise “vigilance” and “prevent” pollution: namely,
the obligation to take account of the uncertain risks involved in the design, preparation and
implementation of any project or form of use re lating to the River Uruguay and the areas affected
by it.
138 3.197. When it requested the indication of provisional measures, Uruguay clearly indicated
that it was committed to respecting that principle 360. Even if, in certain circumstances, there may
appear to be only a potential threat of damage, the precautionary principle requires the adoption of
“cost-effective measures to prevent environmental degradation”.
4. The principle of conducting an environmental impact assessment
(a) The immediate corollary of giving notification in good faith of planned measures on the
River Uruguay is that an environmental impact assessment should be carried out
3.198. The 1975Statute must be interpreted in the light of the principle of conducting an
environmental impact assessment (EIA). The EI A process is intrinsic to implementation of the
principles of information, consultation and prior agreement, which the 1975Statute lays down, as
well as the provisions of the Statute concerning the protection of the river. As has, in fact, been
stressed “without prior assessment there can be no meaningful notification and consultation in most
361
cases of environmental risk” .
3.199. It follows that the principle of conduc ting an environmental impact assessment is an
essential facet of the obligation to prevent pollution and underpins the precautionary principle. It is
a corollary of the premise that “in the field of environmental protection, vigilance and prevention
are required on account of the often irreversible char acter of the damage to the environment an362f
the limitations inherent in the very mechanism of reparation of this type of damage” .

3.200. The environmental impact assessme nt is defined in Principl17 of the
RioDeclaration on Environment and Development. That principle makes it possible to integrate
139 environmental requirements, even at the project planning stage, and to guarantee that they are taken
into account when a project is being designed, prepared and carried out.
3.201. In relation to a shared natural resour ce such as the River Uruguay, conducting an EIA
makes it possible to avert transboundary damage that proposed work would have caused in the
territory of a riparian State. In its commentary on the draft Articles on the Prevention of
Transboundary Harm from Hazardous Activities, th e International Law Commission states that
carrying out an environmental impact assessment “enables the State to determine the extent and
nature of the risk involved in an activity and, consequently, the type of preventive measures it
363
should take” .
3.202. Each State adopts the policies it needs to develop its natural resources and decides on
the measures required to meet the needs of its populat ion. But, in doing so, the State must ensure
that activities carried out in its territory take account of the legally protected interests of other
States. The EIA provides a method of assessing both the positive features of a project and the
known or potential risks for a riparian State. Here again, the various components of the principle
of optimum and rational utilization are apparent, as the Donauversinkung case illustrates:
“[t]he interests of the States in question must be weighed in an equitable manner
against one another. One must consider not only the absolute injury caused by the
neighbouring State but also the relation of the advantage gained by the one to the
injury caused to the other.” 364
(b) The criteria for conducting an objecti ve and comprehensive environmental impact
assessment must be met
140 3.203. An environmental impact assessment must be comprehensive and objective: those are
two essential aspects of the obligation to carry out the assessment. The substance of an
environmental impact assessment determines whether it is, in fact, comprehensive.
3.204 International practice enables us to identify some of the requirements that an
environmental impact assessment must meet. For instance, Article4 of the 1991 Convention on
Environmental Impact Assessment in a Tran sboundary Context (hereinafter “the Espoo
Convention”) provides that an environmental im pact assessment must, at least, contain the
information listed in Annex II to the Convention. Annex II (“Content of the environmental impact
assessment documentation”) sets out the following list:
“(a)a description of the proposed activity and its purpose;
(b)a description, where appropriate, of reasonable alternatives (for example,
locational or technological) to the proposed activity and also the no-action
alternative;

Law Cases (1927-1928), London, 1931, p. 131. - 85 -
(c) a description of the environment likely to be significantly affected by the proposed
activity and its alternatives;
(d) a description of the potential environmental impact of the proposed activity and its
alternatives and an estimation of its significance;
(e) a description of mitigation measures to k eep adverse environmental impact to a
minimum;
(f) an explicit indication of predictive methods and underlying assumptions as well as
the relevant environmental data used.”
3.205. It is also clear from practice that the impact on the natural environment (air, land and
water) and the social impact ⎯ on the health and safety of the population, for example ⎯ must be
365
141 taken into account in an integrated fashion . The reports of the World Bank’s Inspection Panel
highlight the links that must be established betw een the environmental and social impact. For
example, in the Colombia: Cartagena Water Supply, Sewerage and Environmental Management
Project case, the Panel considered that the social risks ⎯ linked to a development project for the
installation of water and sewerage services ⎯ which that project might have for the local
366
communities had not been taken properly into account when the project was evaluated . When
evaluating the proposed construction of a dam in Uganda, the Inspection Panel assessed the
project’s impact on tourism and concluded that th e action plan that was envisaged to protect the
367
interests of the affected communities was not compliant with the Bank’s operational policies .
3.206. The provision of the appropriate in formation and consultation with the States
concerned and the affected local population are integral parts of the EIA principle. The Espoo
Convention, for instance, requires that the releva nt population in the State which may be affected
by a project s368ld be able to participate in the process of assessing the impact on the
environment . Furthermore, Operational Policy 4.01 on Environmental Assessment of the
International Finance Corporation (IFC) provides that “the project sponsor consults project-affected
groups and local non-governmental organizations (NGOs) about the project’s environmental
aspects and takes their views into account”. It further provides that “for meaningful consultations

3 March 1997 amending Directive 85/337/EC on the assessment of the effects of certain public and private projects on
the environment, OJ L 73 of 14March1997, pp.5-15, Art.3. According to Art.29 of the 2004 Berlin Rules of the
International Law Association:
“1. States shall undertake prior and continuing a ssessment of the impact of programmes, projects
or activities that may have a significant effect on the aquatic environment or the sustainable development
of waters. 2. Impacts to be assessed include, among others: (a)effects on human health and safety;
(b)effects on the environment; (c)effects on existing or pros pective economic activity; (d) effects on
cultural or socio-economic conditions; and (e)effects on the sustainability of the use of waters.”

between the project sponsor and the project-affect ed groups and NGOs... the project sponsor
369
supplies relevant material in a timely manner prior to consultation” .
142 3.207. The obligation to consult the public is also recognized by the African Commission on
Human and Peoples’ Rights. In the case of The Social and Economic Rights Action Center and the
Center for Economic and Social Rights v. Nigeria, the Commission concluded that the Government
was under an obligation to allow Ogoni communi ties which might be affected by hazardous
activities access to information, and it confir med that those communities were entitled to
participate actively in decisions on economic development 37.
3.208. The reports of the Inter-American Commission on Human Rights shed further light on
the issue. Although citing the specific obligatio n to engage in prior consultation with the
indigenous peoples, they nonetheless accentuate the obligation on the States to ensure that the
public is able to participate in decision making in relation to economic development measures 371.
3.209. Finally, it must be stressed that an environmental impact assessment must take
account of the international commitments of the State in whose territory a project is planned. That
principle applies to all projects envisaged on the River Uruguay.
C. The international instruments applicable to the current dispute
3.210. As already explained above, the 1 975Statute contains clauses that refer to
international instruments and conventions 372. The latter apply in relations between Argentina and
143 Uruguay pursuant to the 1975 Statute and enlarge upon and supplement the obligations incumbent
on Argentina and Uruguay under that Statute.
1. The international conventions on environmental protection
(a) The applicable multilateral conventions
(i) Conventions on nature conservation
3.211. The Convention on Wetlands of Inte rnational Importance especially as Waterfowl
Habitat adopted in Ramsar in 1971 (hereinafter “the Ramsar Convention”) and the Convention on
International Trade in Endangered Species of Wild Fauna and Flora adopted in Washington in 1973
(hereinafter “the CITES Convention”) contain oblig ations that are important in terms of the
protection of the RiverUruguay and its resources. Argentina ratified the Ramsar Convention on
4September1992 and the CITES Convention on 8 January1981. Uruguay ratified the Ramsar
Convention on 22 September 1984 and the CITES Convention on 2 April 1975.

37Arts. 1 and 41 (a) of the 1975 Statute. - 87 -
3.212. If a site is entered on the Ramsar List , the national government is required to take all
measures necessary to maintain all of its speci fic ecological characteristics. The Ramsar
Convention attaches particular importance to the links between the protec tion of wetlands and the
373
protection of watercourses and the related aquatic resources . One of the two sites which
Uruguay has entered in the Ramsar List is situat ed on the RiverUruguay. This site is called
Esteros de Farrapos e Islas del Río Uruguay 374.
3.213. The decisions which the Conference of the Parties to the Ramsar Convention has
adopted clarify the substance of the obligations under the 1975 Statute. Thus, the meaning of the
144 expression “rational utilization” 375 was clarified at the 3rd Conference of the Parties in 1987, and
updated at the 9th Conference of the Parties, held in Kampala in 2005: “Wise use of wetlands is
the maintenance of their ecological character, ach ieved through the implementation of ecosystem
approaches within the context of sustainable development.” 376
3.214. That definition takes account of the principle of sustainable development and the
concept of ecosystem. In that connection, the 1975 Statute is of major significance in guaranteeing
that the site is permanently pr eserved in accordance with the obliga tions laid down in the Ramsar
Convention.
3.215. The CITES Convention is designed to pr otect the endangered fauna and flora that are
listed in the three annexes to the Convention according to the gravity of the threat of extinction that
they face. Protecting a specific environment, su ch as the River Uruguay, contributes to protecting
the fauna and flora listed in the annexes to the CITES Convention.
(ii) The Convention on Biological Diversity
3.216. The 1992 Convention on Biological Diversity plays a key role in terms of the use and
permanent protection of the RiverUruguay and its resources. Argentina and Uruguay are both
parties to the Convention 377.
145 3.217. The Convention defines biological diversity as “the variability among living
organisms from all sources, including, inter alia, terrestrial, marine and other aquatic ecosystems

Art.3(1) of the Ramsar Convention provides that: “T he Contracting Parties sha ll formulate and implement
their planning so as to promote... as far as possible the wisuse of wetlands in their territory.” [Translator’s note:
while the 1975Statute refers to “rational utilization” (utilisation rationnelle”), the Ra msar Convention refers to
“wise use” in the English version but, also, “utilisation rationnelle” in the French.]

and the ecological complexes of which they are part: this includes diversity within species,
between species and of ecosystems” 378.
3.218. The Convention on Biological Diversity lays down the criteria for the sustainable use
of any natural resource. According to the Convention, the term “sustainable use” means “the use of
components of biological diversity in a way and at a rate that does not lead to the long-term decline
of biological diversity, thereby maintaining its potential to meet the needs and aspirations of
379
present and future generations” .
3.219. Under the Convention on Biological Diversity, Argentina and Uruguay are required to 380
integrate conservation and sustainable use of biological diversity into their domestic policies and
to “adopt measures relating to the use of biological resources to avoid or minimize adverse impacts
381
on biological diversity” . The Convention requires the States to implement the principle of an
environmental impact assessment to prevent da mage to biological diversity. Article14 entitled
“Impact Assessment and Minimizing Adverse Impacts” requires the States to introduce
“appropriate procedures requiring environmental impact assessment of [their] proposed projects
that are likely to have significant adverse effects on biological diversity with a view to avoiding or
minimizing such effects . . .” 382.
3.220. The Conference of the Parties to the Convention on Biological Diversity looked at the
relationship between biological diversity and touris m. In that context, it adopted a resolution
entitled “Biological diversity and tourism”. That resolution acknowledges that “sustainable
383
146 tourism can provide significant benefits to biodiversity conservation” . Consequently, sustainable
tourism ⎯ as envisaged by Argentina in the RiverUruguay region and compatible with the
1975 Statute ⎯ contributes to preserving biological diversity.
(iii) The Stockholm Convention on Persistent Organic Pollutants (POPs)
3.221. The Convention on Persistent Organic Po llutants is crucial. It makes it possible to
determine the hazardous and polluting nature of the substances and manufacturing techniques
384
linked to the construction of pulp mills . The Convention contains obligations requiring the
States to adopt measures to protect human health and the environment.
3.222. The Convention requires the parties to use the best available techniques for the
industrial activities listed in Annex C. That annex lays down the obligation to reduce or
“eliminate” the “polychlorinated dibenzo-p- dioxins and dibenzofurans” (PCDDs/PCDFs),

The Convention on Persistent Organic Pollutants is not the only instrument to highlight the hazardous nature of
pulp mills. See also para.13 of Ann.I of the Espoo Conven tion, para.18 of Ann.I of Council Directive 97/11/EC of
3 March 1997 amending Directive 85/337/EC on the assessment of the effects of certain public and private projects on

Sustainable Use of the River Danube. - 89 -
385
commonly known as dioxins and furans . The document lists four categories of industrial source
which have the potential for comparatively high fo rmation and release of these chemicals into the
environment. Pulp manufacturing processes fall into those categories. According to the Annex,
147 “production of pulp using elemental chlorine or chemicals generating chlorine for bleaching” has
“the potential for comparatively high forma tion and release of these chemicals into the
environment” 386.
3.223. The Stockholm Convention sets the objective of eliminating dioxins and furans,
requiring the development of an action plan within two years of the date of entry into force of the
Convention to “promote the application of ava ilable, feasible and practical measures that can
expeditiously achieve a realistic and meaningf ul level of release re duction or elimination” 387.
Uruguay adopted its action plan to implement th e Stockholm Convention in May2006. In its
action plan, Uruguay identifies the production of pulp as a source of chemical production and states
that a significant increase in the production of “blanqueada” pulp is anticipated 38. Although one
of the objectives of the Convention is to re duce or eliminate dioxins and furans, Uruguay
acknowledges that it has no plans to introduce meas ures to reduce or eliminate those chemicals.
The Plan adds that Uruguay “does not envisage si389 ficant changes in emissions in the short term,
except for the pulp manufacturing sector” !
(b) Co-operation agreement to prevent and combat incidents of pollution of the aquatic
environment caused by hydrocarbons and other harmful substances
148 3.224. The Co-operation Agreement to Preven t and Combat Incidents of Pollution of the
Aquatic Environment caused by Hydrocarbons and other Harmful Substances, which was
concluded in Buenos Aires on 16 September 1987 between Argentina and Uruguay, contains
obligations designed to prevent incidents of po llution and safeguard the quality of the aquatic
environment, as defined in the 1973 Treaty concerning the Río de la Plata and the corresponding
Maritime Boundary390d the 1961 Treaty c oncerning the Boundary Constituted by the
River Uruguay .

The document, which is drafted in Spanish, states that the production of paper pulp
“within the industrial category is the only activity iden tified as a possible source of effluent polluted by
dioxins and furans. The only company that currentl y produces bleached kraft pulp is a medium-sized
company, and it intends converting its current production system in the short term from a system based on
elemental chlorine to an entirely chlorine-free system. It is planned to set up two further bleached kraft
cellulose factories, with a total production volume of 1,410,000 tonnes per annum using chlorine dioxide
as a bleaching agent. According to IPPC, that production technology is among the best available.
There are other chlorine-free pulp mills in Uruguay, with recycling playing a critical role in
production. In some cases, there is no system for treating effluent and/or th e waste generated is not
properly treated. Currently, the energy consum ption of wood in the paper sector accounts for
approximately 18percent of total consumption in the industrial sector.” (Plan Nacional de
Implementación, Uruguay, May 2006, p. 63. Anns., Vol. VII, Ann. 8.)

The preamble expresses the desire of the Parties to “maintain and extend co-operation between the two
countries to prevent incidents of pollution and combat their e ffects in the aquatic environmen t, as defined in the Treaty
concerning the Río de la Plata and the corresponding Mari time Boundary and the Treaty concerning the Boundary
Constituted by the River Uruguay”(Anns., Vol. II, Ann. ). - 90 -
3.225. Article 5 of the Agreement requires th e two States to work towards reducing the risk
of incidents and to enhance the safety of operati ons which could pollute the aquatic environment
“in accordance with the international instruments in force and the laws, decrees and regulations laid
down by each Party”. Article 6 requires the Partie s to exercise vigilance in relation to the quality
of the aquatic environment and its resources. The Agreement also confers responsibilities for
combating incidents of pollution on the Administrative Commission of the Río de la Plata, the Joint
391
Technical Committee for the Maritime Boundary and CARU .
2. The 1975 Statute and the guidelines and recommendations
issued by international technical bodies
3.226. On the basis of the 1975Statute, Argentina and Uruguay have undertaken to protect
the aquatic environment “in keeping . . . with th e guidelines and recommendations of international
technical bodies” 392. These instruments to which Article41 (a) refers are those adopted by the
international organizations and institutions competent in the areas covered by the 1975 Statute.
3.227. We cited earlier the decisions adopted by the conferences of the parties set up in
relation to the various conventions on environmenta l protection. We may also cite the guidelines
and recommendations of certain specialized agencies within the United Nations family, such as the
149 World Health Organization (WHO).
3.228. The World Health Organization’s Guidelines for Drinking-Water Quality, which were
393
updated in 2006, are among the category of instruments to which Article41 (a) refers . Their
purpose is to set in place a preventive framework to secure the supply of clean water and work to
protect the health of the population.
3.229. The World Health Organization’s Gu idelines for Drinking-Water Quality contain
chapters devoted to the effects of chemicals, stressing that the States must take preventive measures
394
to avert water pollution . According to the Guidelines:
“Identification of the potential for c ontamination by chemicals from industrial
activities and human dwellings requires assess ment of activities in the catchment and
of the risk that particular contaminants may reach water sources. The primary
approach to addressing these contaminants is prevention of contamination by
395
encouraging good practices.”
In addition, the Guidelines lay down standa rds concerning the use of certain hazardous
substances by the pulp industry.
Conclusion
3.230. All of the rights and obligations that ha ve been analysed in this Chapter constitute the
law applicable to the present dispute. The 1975 Statute is an instrument that is demanding in

present dispute includes the principles and rules of international law on international watercourses
and the environment, and the international legal in struments that are applicable by virtue of the
referral clauses contained in Articles 1 and 41 (a) of the Statute. The breaches of law that Uruguay
has committed must be viewed in the light of th e whole corpus of law applicable to the present
dispute.
3.232. Those breaches include, inter alia, the infringement of specific international rules:
breaches of the obligations to exch ange information, to provide no tification and to consult with a
view to reaching prior agreement, as provided for in Chapter II of the Statute, as well as breaches
of the obligations which the Statute of the River Uruguay prescribes in relation to safeguarding the
quality of the water, the régime of the river and its ecosystem. - 92 -
C HAPTER IV
B REACHES BY U RUGUAY OF THE PROCEDURAL OBLIGATIONS
PRESCRIBED IN CHAPTER II OF THE 1975 S TATUTE
4.1. In Chapter III Argentina set out the cont ent of the obligations incumbent on the Parties
153
under ChapterII of the 1975 Statute where planned works are liable to affect navigation, the
régime of the river or the quality of its waters6. The aim of the present chapteris to show that
Uruguay has not discharged those obligations, crucial though they are to the overall structure of the
Treaty. Indeed, each time Uruguay has authorized such works, it has done so without notifying or
informing CARU in advance, and without waiting for CARU and Argentina to give their response
to the works. By so doing, it quite simply prevented the procedure provided for under Articles7
397
to 12 of the 1975 Statute from being able to be followed in the usual way .
4.2. It was against the background of the firs t contested authorization, which relates to the
CMB mill, that Uruguay tried to find a justifi cation for its wrongful conduct. That is why
Argentina examines that authorization in great detail below398. It should be noted that Uruguay’s
conduct in relation to subsequent authorizations wa s similar. Therefore, the analyses of Uruguay’s
attempts to justify its wrongful conduct with regard to the CMB mill are equally applicable to the
other authorizations issued in violation of the 1975 Statute, whether in respect of:
⎯ the initial failure to consult CARU (which led to the total paralysis of any procedure required
under Chapter II of the Statute) (Section I),
⎯ the failure to communicate relevant informati on to CARU and, through the Commission, to
Argentina (Section II) or
⎯ the fact that Uruguay pursued its course regard less of opposition from Argentina and despite
the absence of a settlement to the dispute (Section III);
as a result of that conduct, Uruguay has committed a material breach of the 1975 Statute and
thereby devoided one of its substantive objects of any purpose (Section IV).
154 Section I
Uruguay has systematically authorized all plans without consulting CARU
(Article 7, first and second paragraphs, of the 1975 Statute)
4.3. There can be no dispute that the Botnia and CMB plans fall within the scope of the
provisions of the 1975 Statute. If works of that kind were excluded from their scope, the Statute
would be wholly without substance.
4.4. The pulp industry is one of the most polluting of all industries and the size of the
planned mills leaves no room for doubt as to the need to submit them to the procedure provided for
396
See Chap. III, Sec. II, part B above.

in ChapterII of the Statute, given their poten tial effects on the quality of the waters of the
River Uruguay, the areas affected by it, and the régi me of the river. That observation is confirmed
by the very large number of international treaties and national laws which require plans of this type
to undergo a mandatory environmental impact assessment and other preventive measures, given the
399
inherent risks they pose to the environment around them .
4.5. Various international conventions list large pulp mill plans among projects which have
harmful effects on the environment. This is the case with the Stockholm Convention on Persistent
Organic Pollutants of 22May2001, the objective of which is to protect human health and the
environment from the effects of those substances (Art.1) and which in Article5 requires parties,
including Uruguay, to take at a minimum certain measures to reduce the releases of various
categories of chemicals listed in Annex C to the Convention. Part II of that Annex identifies four
industrial source categories which are described as likely to have “the potential for comparatively
high formation and release of these chemicals to the environment”. Among them, the Annex
makes reference to: “ (c)Production of pulp using elemental chlorine or chemicals generating
elemental chlorine for bleaching”.
4.6. Other international conventions set out the dangers to the environment which are
155
inherent in pulp production. AppendixI to the Espoo Convention of 1991 on Environmental
Impact Assessment in a Transboundary Context id entifies projects which are required to be the
subject of a mandatory EIA because they are “ likely to cause a significant adverse transboundary
400
impact” . The 17 activities listed in the Appendix incl ude: “13. Pulp and paper manufacturing
of 200 air-dried metric tonnes or more per day”.
4.7. The same approach is to be found in European Community Council Directive 97/11/EC
of 3 March 1997 amending Directive 85/337/EEC on the assessment of the effects of certain public
and private projects on the environment 401, AnnexI of which also includes the industrial
production of paper among activiti es which are required to be the subject of mandatory EIAs
because of the risks they pose to the environment. The Annex specifically refers to:
“18. Industrial plants for the
(a) production of pulp from timber or similar fibrous materials;
(b) production of paper and board with a production capacity exceeding 200tonnes
per day.”
156 4.8. Similarly, international development banks require significant pulp production projects
to be the subject of an EIA before funding can be considered. The IBRD and the IFC include
large-scale pulp production projects in Category A, the category for which a full EI402s required, as
the project may have diverse and significant environmental impacts . Likewise, the
environmental policy of the European Bank for Reconstruction and Development (EBRD) divides
399
See Chap. III, Sec. III.B (4).
400
Art. 3 (1). Under Art. 2 (3) of the Espoo Convention “[t]he Party of origin shall ensure that in accordance with
the provisions of this Convention an envi ronmental impact assessment is undertaken prior to a decision to authorize or
undertake a proposed activity listed in Appendix I that is likely to cause a significant adverse transboundary impact”.

projects into three categories, listed in the Anne xes as Categories A, B and C. Category A relates
to projects deemed to be the most dangerous fo r the environment (projects which “could result in
potentially significant adverse future environmenta l impacts”) and which are required to be the
subject of a mandatory EIA:
“13. Industrial plants for the: (a)production of pulp from timber or similar
fibrous materials; (b)production of paper and boa403 with a production capacity
exceeding 200 air-dried metric tonnes per day.”
4.9. Moreover, the same is true of Uruguayan law. Article6 of Law No.16.466 of
19 January 1994 on the protection of the environmen t against degradation, destruction or pollution
requires an EIA to be performed in advance for “activities, construction work or works, whether
public or private”, which relate to “industrial complexes . . . or installations which by their nature
or scale may have a serious environmental impact . . .” (emphasis added) 40.
4.10. There therefore appears to be no question that the pulp mill projects planned or carried
out by Uruguay are subject to the obligations entere d into by the Parties in the 1975 Statute. They
are clearly liable to affect “navigation, the régime of the River or the quality of its waters” and to
“cause significant damage to the other Party”.
157 4.11. In accordance with Article 7, first paragraph, of the 1975 Statute,
“If one Party plans to construct new ch annels, substantially modify or alter
existing ones or carry out any other works which are liable to affect navigation, the
régime of the River or the quality of its waters, it shall notify the Commission, which
shall determine on a preliminary basis a nd within a maximum period of 30days
whether the plan might cause significant damage to the other Party.”
4.12. Uruguay was therefore under the obliga tion to consult and inform CARU of the
planned mills it was thinking of constructing, prior to granting authorizations. The above provision
clearly refers to consultation and notification prior to any action concerning the authorization for
405
construction . The wording of ChapterII of the 1975 Statute leaves no room for ambiguity as
regards the mechanism for prior information and c onsultation prescribed in the 1975 Statute. It
states: “If one Party plans to construct... or carry out... works... it shall notify the
406
Commission”, which will give a response to “the plan” (Art.7) . CARU has 30 days to
“determine on a preliminary basis . . . whether th e plan might cause significant damage to the other
Party”. Only if CARU determines that the plan will not cause significant damage can the Party
concerned carry out or authorize the planned works. The first paragraph of Article 7 clearly refers
to a requirement to provide notification prior to any action relating to the construction of works by
either party 407and, where the party will not be carrying out the work itself, prior to the

404
See http://www.parlamento.gub.uy/Leyes/Ley16466.htm.
405See CR 2006/46, p. 17, para. 7 (Cerutti).
406See also Art.13: “The rules laid down in articles 7 to 12 shall apply to all works referred to in article7...
which either Party plans to carry out within its jurisdiction in the River Uruguay . . .”
407This analysis is confirmed by the En glish and Spanish versions of other provisions of the Statute: in the
English version, Arts. 27 and 29 refer to the procedure laid down in Arts. 7 to 12 where the use of the waters of the River
“is liable to affect the régime of the River or the quality of its It is also confirmed by the Joint Declaration of
18 Sept. 1976 in which the Presidents of Argentina and Uruguay - 95 -
authorization to proceed with construction which it is to grant to a private person or undertaking.
158 The latter situation is the one which has arisen in the present case. It involves authorizations
granted by Uruguay to the ENCE and Botnia undertakings.
4.13. None of the authorizations to proceed with construction issued by Uruguay complied
with the obligation to hold prior consultations with or provide prior notification to CARU for it to
determine whether Uruguay was able to carry out or authorize the works concerned.
A. The authorization of 9 October 2003 concerning the CMB mill
4.14. On 9October2003, the Government of Uruguay authorized the Spanish company
ENCE to construct a pulp mill on the outskirts of the town of Fray Bentos (Río Negro Department),
408
the project name being “Celulosa de M’Bopicuá” . That authorization was granted despite the
fact that CARU had already requested information on the project, and in spite of Uruguayan
promises to forward to CARU the information prescribed under Article 7 of the Statute 409.
(i) Uruguay has expressly acknowledged that it failed to comply with the obligation to
consult CARU
4.15. Uruguay itself has acknowledged on several occasions that it has not followed the
procedure prescribed in Article 7 of the 1975 Statute.
4.16. Initially the Uruguayan explanation consis ted in stating that the obligation to notify
CARU, in accordance with Article7 of the 1975 Statute, exists only where works are “liable to
159 affect navigation, the régime of the River or the quality of its waters” and that since that was not
the case where the CMB mill was concerned, Uruguay did not have to discharge that obligation.
4.17. That position is implicit in the Urugua yan Note of 27 October 2003 and explicit in the
explanation given by the Uruguayan Minister for Foreign Affairs, Didier Opertti, to the Uruguayan
Senate on 26November2003. In the former ca se, Uruguay tries to justify the forwarding of
documentation to Argentina ⎯ which was very fragmented and in any event late in coming and,
moreover, was not sent via CARU ⎯ concerning the authorization to proceed with the construction
of CMB simply on the basis of “the spirit a nd framework of cooperation and good neighbourly
relations which we are glad to say is characteristic of relations between Uruguay and Argentina” 41.
“note with deep satisfaction that the Statute, which has now entered into force in implementation of the
provisions of the 1961 Treaty concerning the Boundary Constituted by the River Uruguay, is imbued with
the same fraternal spirit that resulted in the signing of the Treaty concerning the Río de la Plata and the
corresponding Maritime Boundary, as Article1 thereo f reiterates the aim of establishing the joint
machinery necessary for the optimum and rational utiliz ation of the River Uruguay, and, in addition, at
the same time includes, in the bilateral legal regime it est ablishes, the principle of prior agreement in
relation to any work or activity that either of th e Parties proposes to carry out in the shared section , or
that the Argentine Republic carries out in the upper sect ion” (Anns., Vol. II, Ann. 34, see also para. 3.81
above).

Argentine Embassy in Uruguay, Anns., Vol. II, Ann. 21. - 96 -
4.18. It should be noted that at that point, Argentina had already indicated to CARU that it
was of the view that Article 7 of the 1975 Statute was applicable, a point which was not disputed
by the Uruguayan delegation to CARU 411. The same Uruguayan Note of 27 October 2003 sets out
the internal procedure foll412d and considers that that procedure “leads to the conclusion that all
precautions were taken” . It is clear that Uruguay was acting at that point as if there was no need
to follow the procedure prescribed in the 1975 Statut e before granting an authorization to proceed
with construction of the CMB mill, despite413l the pr omises to the contrary made previously by the
State authorities at the highest level and CARU’s insistence that the prescribed information
should be communicated to it.
4.19. The statement by the Minister for Foreign Affairs, Mr.Opertti, to the Uruguayan
Senate on 26 November 2003 is a perfect illustra tion of the Uruguayan position set out one month
previously in the Note from his Ministry. The Mini ster stated first that the works in question were
160 entirely national works and therefore “subject solely to the Uruguayan legal order” 414. He infers as
a result that Uruguay was not under an obligation to follow the procedure prescribed in Articles 7
and 8 of the 1975 Statute: “it is natural that th e Government of Uruguay should not be obliged to
refer this matter to the Commission. That woul d be abandoning our responsibilities, which the
Government of Uruguay does not intend to do; it is as simple as that” 41.
4.20. Foreign Minister Opertti said in the same statement that industrial projects have been
carried out on the Argentine side without any reaction or protest from Uruguay. Mr.Opertti
offered no clearer explanation, although he let it be understood that Argentina had not consulted
CARU in similar cases. Nothing could be further from the truth. First, because no works on such a
scale have ever been constructed on the Argentin e bank. Secondly, becau se Argentina has always
fulfilled its obligations arising under Articles 7 et seq. of the Statute. As pointed out in Chapter III,
not only has Argentina not hesitated to forwar d information prescribed under Article7 of the
Statute, it even abandoned one project and did no t grant an authorization to proceed with the
construction of works in one case ⎯ even though the works con cerned were upstream of the
Argentine-Uruguayan s416ion of the River Uruguay ⎯ when CARU ruled that they might cause
significant damage .
4.21. The position taken by Uruguay in an atte mpt to justify non-consultation of CARU on
the grounds that the works were not going to cause significant damage to the river was
subsequently reiterated by the current Presi dent of the Uruguayan Delegation to CARU,
MsPetrocelli, in her statement to the Envi ronment Committee of the Uruguayan Senate on
161 12 September 2005. The Chairman of the Senate Committee asked the following question:
“Article7 refers to the need for CARU to be consulted and for the two
delegations to give their consent to the plan in question. The legal interpretation is to

the effect that since there was no element that could cause contamination, this prior
consent was not necessary. Is that the right interpretation?” 417
4.22. Ms Petrocelli’s reply was in the affirmative 418.
4.23. However, under the arrangement of 2March2004 with his Argentine colleague
Mr. Bielsa, Foreign Minister Opertti declared his agreement to submitting the CMB plan to CARU,
thereby affirming the applicability of the 1975 Statute to the plan and CARU’s competence to
make a determination on it. Unfortunately, Uruguay failed to honour the arrangement 419.
4.24. The hearings on the request for the indication of provisional measures submitted by
Argentina were another occasion where Uruguay acknowledged its obligation to consult CARU on
the CMB project: in a line of argument which was wholly inconsistent with its previous
contention, Uruguay contended this time that it had “discharged the obligations imposed upon it by
420
Articles 7 et seq. in good faith” .
(ii) Attempts by Uruguay to justify its failure to discharge its obligations are inconsistent
and without foundation
4.25. Thus, after having argued that pursuan t to Article7 it was under no obligation to
submit the CMB project to CARU, Uruguay came to the view that it had complied with the
obligations incumbent on it under Articles 7 et seq. in respect of the plan. This strange U-turn in its
162
position speaks volumes on the seriousness of Uruguay’s attempts to justify its conduct.
4.26. The explanations given by Uruguay prior to the request for the indication of
provisional measures as to why CARU was not cons ulted over the CMB plan openly conflict with
the wording of Article 7, are contrary to plain common sense and are refuted by the description of
the plan given by the competent Uruguayan authorities themselves.
4.27. Argentina has already explained in deta il the meaning and scope of Article7 of the
1975 Statute 421and there is no need to go back over that gr ound: the fact that one of the Parties is
of the view that a set of significant works will not cause any damage does not mean that there is no
requirement to consult and notify CARU in advanc e. As Mr. González Lapeyre and Mr. Flangini
(both Uruguayan negotiators of the Statute and form er CARU delegates) have clearly explained in
their commentary on the 1975 Statute, “in order for a riparian State to be able to assess whether the
works to be carried out by another such Stat e on a shared watercourse might cause significant
damage to the latter, it must be informed about the plan concerned in advance” 42.

Chapt. III, p. 74. Anns., Vol. VII, Ann. 2. - 98 -
4.28. The alleged Uruguayan justification, if th at is what it was, would render Chapter II of
the 1975 Statute meaningless, because it would mean that the State wishing to carry out works
would take a decision which in the first instance ⎯ i.e., before any assessment is made, if
necessary, by the other Party ⎯ lies with the Commission. Moreover, under Article7, second
paragraph, of the 1975 Statute, if CARU does not give a response, the effect of its non-decision is
exactly the same as the effect produced where it finds that a plan might cause significant damage to
the other Party. In other words, only where CARU decides that the plan cannot cause such damage
163 does the procedure stop at that point, without there being any need for the Party concerned to notify
and inform the other Party, through CARU, prior to carrying out or authorizing the works.
4.29. The practice referred to in Chapter III of this Memorial shows that works much smaller
in scale than those of the CMB and Orion mills complied with the procedure prescribed in the
423
1975 Statute . It is sufficient to state here that the construction of Port M’Bopi424, the property
of ENCE, was carried out once CARU had authorized the works in 2001 . Mr.Opertti, the
Minister for Foreign Affairs of Uruguay, also noted this point in his statement to the Uruguayan
Senate of 26 November 2003:
“I would like to supply one further detail. During construction of Port
M’Bopicuá and once the appropriate decision had been reached in that regard, work
was carried out in order to determine whether a natural condition or the navigability of
the River may possibly be at risk.” 425
The construction of a pulp mill on the scale of th e CMB mill is clearly a work whose importance
far exceeds that of Port M’Bopicuá as regards the lik elihood of affecting the régime of the river or
the quality of its waters.
4.30. The requirement to consult CARU unde r the machinery for prior notification and
consultation prescribed in the 1975 Statute is an in ternational obligation and exists independently
of the extent of any precautions, impact studies, legislative and regulatory measures and so on,
whether taken by Uruguay or not. The response to the question whether the works at issue “are
liable to affect navigation, the régime of the Rive r or the quality of its waters” is a matter for
CARU (“which shall determine on a preliminary basis and within a maximum period of 30days
whether the plan might cause significant damage to the other Party”). The matter does not,
therefore, lie within the discretionary power of the Party concerned.
4.31. In that regard, it is very significant that DINAMA itself classified the CMB plan under
164
the relevant Uruguayan legislation in category“C ”, in other words the category which includes
“activities, constructions or works, the executi on of which may produce negative environmental
impacts of qualitative and quantitative significan ce, whether or not preventive or mitigating
426
measures are foreseen” .

Land Use Planning and Environmental Affairs on 9Oct.2003 and 14 Feb. 2005 respectively, Anns., Vol.VII, Anns.9
and 10. - 99 -
4.32. The Uruguayan Government was fully aware that projects of that nature were required
to comply with the procedure prescribed in Chap ter II of the 1975 Statute and deliberately decided
not to follow it. That is a breach of the obliga tion to consult CARU. Uruguay’s first attempt at an
explanation, namely that the works would not cause significant damage to the river, which
implicitly acknowledges that the procedure prescribed in Article7 was not followed, must be set
aside.
4.33. Similarly, it is clear that the second argument put forward by Uruguay, namely that the
authorization to construct the CMB plant was gran ted in accordance with its internal law, cannot
release Uruguay from the international obligations arising under Article 7 of the 1975 Statute. As
noted in Article 3 of the Articles of the International Law Commission on Responsibility of States
for Internationally Wrongful Acts:
“The characterization of an act of a State as internationally wrongful is
governed by international law. Such ch aracterization is not affected by the
characterization of the same act as lawful by internal law.” 427
165 The ILC commentary states in that regard tha t: “a State cannot, by pleading that its conduct
conforms to the provisions of its internal law, escape the characterization of that conduct as
wrongful by international law” 42.
4.34. The case law of the Court is consiste nt as regards the relationship between the
existence of an international obligation and the pr ovisions of internal law. The Permanent Court
has consistently held that:
“it is a generally accepted principle of intern ational law that in the relations between
Powers who are contracting Parties to a treaty, the provisions of municipal law cannot
prevail over those of the treaty” 429.
4.35. The Court has also ruled that:
“Compliance with municipal law and compliance with the provisions of a treaty
are different questions. What is a breach of treaty may be lawful in the municipal law
and what is unlawful430 the municipal law may be wholly innocent of violation of a
treaty provision.”

4.36. Having become convinced of the inhere nt weakness of the position it had maintained
until the hearings before the Court on 8 and 9 Ju ne 2006, Uruguay performed a spectacular U-turn
in its arguments at those hearings. Uruguay is no w of the view that the project for the CMB mill
“was formally brought to the attention of CARU ... on 8July2002, when representatives of the
166 431
mill supplied CARU with the relevant information” . All that there is as “evidence” for that
statement is a letter from ENCE of 24August20 04 addressed to the President of CARU which
states: “As you will recall, in July 2002 we vis ited your offices with the purpose of informing the
432
Commission which you preside over about the project of installing a pulp mill in M’Bopicuá.”
4.37. It is obvious that these so-called privat e dealings do not constitute performance of the
obligation incumbent on the Contracting Parties under Article7 of the Statute. CARU naturally
has contacts with public and private entities. It regularly receives mail and visits from natural
persons, trading companies, NGOs, associati ons in general, State bodies and bodies from
international organizations. Such correspondence an d visits relate to activities linked to CARU’s
powers. In no way can they supplant the requirement to supply information which is incumbent on
the Parties pursuant to Article 7 of the Statute and they have never been interpreted as fulfilling the
condition prescribed in that provision. The wording of Articles 7 et seq. is clear: they read “if one
Party plans to construct”, “the Party concerned”, the “Party [which] may carry out or authorize the
work planned”. That point is corroborated by the fact that CARU requested information on the
project after the visits referred to took place.
4.38. The President of the Uruguayan delega tion to CARU, Ms Petrocelli, acknowledged in
the clearest of terms in her presentation to the Uruguayan Senate of 12 December 2005 that:
“raising issues is a matter for the State. This particular case was introduced out of the blue.
In diplomatic terms, the Party is the body which should introduce the matter and give
notification that it is going to carry out works, whether public or private, and give sufficient
167 433
notice thereof.”
4.39. That represents a further acknowledgment that Uruguay has failed to comply with the
first stage prescribed in Article 7 of the Statute. In no circumstances can a mere initial contact by a
private company supplant formal consultation of CARU by the Party concerned when the
mechanism for prior notification and consultation prescribed in the Statute had not even been set in
train.
4.40. Uruguay also stated in its pleadings that “on 10 October 2003 CARU approved a plan
434
for monitoring and studying construction of the mill” . No reference is given. That statement is,
quite simply, false. On the contrary, the minutes for that meeting of CARU state very clearly that:
“once the material is available, and we hope DINAMA will forward it to us as soon as
possible, the relevant technical meetings will be held for the purposes of carrying out
43CR 2006/47, p. 38, para. 16 (Condorelli), citing the statement given on oath by Ms Petrocelli, President of the
Uruguayan delegation to CARU, as set out in the Observations of Uruguay submitted to the Court on 2June 2006
(Vol. II, Exhibit 1).

the analyses and assessments necessary for the plan, in accordance with the procedure
435
prescribed in Article 7” .
4.41. That statement was made one day after the authorization issued by DINAMA and in
ignorance of the fact that that authorization even existed. Clearly, on 10October2003, Uruguay
had not discharged its obligations pursuant to Chapter II of the Statute.
4.42. During the same pleadings, Uruguay also claimed that: “On the same day, Uruguay
gave its prior environmental authorization for th e mill and notified the President of the Argentine
436
delegation to CARU, who was the President of CARU at the time.” That is not so:
⎯ first, the initial environmental authorizati on was granted for CMB on 9October2003, not
168
10October, in other words one day before th e CARU meeting, without CARU even being
aware of the authorization;
⎯ secondly, no notification whatever was given to the President of the Argentine delegation;
⎯ thirdly, not only was no notification whatever given either to CARU or Argentina, but it was
Argentina which had to call an extraordin ary meeting of CARU one week later, on
17 October 2003, to discuss this serious matter.
437
4.43. Indeed, it is apparent from the minutes of that extraordinary meeting that the
President of CARU had ascertained from the Ar gentine Ambassador to Montevideo that the
Uruguayan Ministry of Housing, Land Use Planning and Environmental Affairs (MOVOTMA) had
authorized CMB to be built without consulting CA RU. He left no room for doubt that this was
incompatible with Article 7 of the Statute. Fu rthermore, the President of CARU referred expressly
to Article12 (the trigger for recourse to the In ternational Court of Justice) “in the event of a
difference of opinion” and clearly noted that “the MOVOTMA decision ought to have been
declared after the prescribed mechanism had been applied” 43.
4.44. The Uruguayan delegation did not dispute what the President of the Argentine
delegation said. The Uruguayan delegation appeared , according to its President, to be unaware of
the authorization. Indeed he stated “as a dele gation we are not in a position to put forward or
formulate other types of consideration since we do not have all the facts, including facts that we
could forward by way of background information to the Commission” 43. A strange way indeed for
Uruguay to “discharge its obligations pursuant to Article 7”: the Uruguayan delegation to CARU
itself admits it does not have all the facts, even where they would be indispensable pieces of
information for the Commission.
169 4.45. There can be no clearer basis for establishing that Uruguay failed to submit the CMB
plan to CARU than the words of the President of the Uruguayan delegation. After stating that she
was unaware of the Ministry’s decision and that her delegation was of the belief that that decision

referred only to one project, she concluded by say ing: “That project has not got this far [to
440
CARU].”
4.46. If it were true that Uruguay was of th e view that its prior dealings fulfilled the
obligations prescribed in Article 7, the Uruguayan delegation would not have failed to say as much.
There is not the slightest trace in the CARU minutes of a claim by Uruguay that the procedure
prescribed in the Statute was complied with. On the contrary, Uruguay has once again expressly
acknowledged that it failed to follow the directions set out in Article 7 of the Statute.
4.47. In conclusion, by authorizing the c onstruction of the CMB mill without consulting
CARU, Uruguay violated the obligation incumbent on it pursuant to Article 7 of the 1975 Statute.
There is no justification for that breach, nor are there any grounds to excuse its wrongfulness. It
not only constitutes in and of itself a wrongful international act against Argentina but also
precludes any possibility of the subsequent articles being implemented.
B. The authorization of 14 February 2005 concerning the Orion mill
4.48. On 14February2005 the Government of Uruguay authorized the Finnish company
Botnia to construct a pulp mill, the project name being “Orion”, on the outskirts of the town of
FrayBentos (Río Negro Department) on the left bank of the River Uruguay, less than 7km from
the CMB mill. Once again, the authorization was granted despite the fact that CARU had
170 requested information on the project without having been officially notified of it, and without the
information required under Article 7 having been forwarded 441.
442
4.49. It is difficult to imagine how a project on such a scale , the largest industrial project
ever planned for the shared section of the River Uruguay, can have been regarded by Uruguay as
not falling within the scope of Article7 of the Statute. Even the report drawn up by DINAMA,
which classified the CMB plan under the relevant Uruguayan legislation in category“C”
(“Activities, constructions or works, the execu tion of which may produce negative environmental
impacts of qualitative and quantitative significan ce, whether or not preventive or mitigating
measures are foreseen”), is evidence of the incomplete and unsatisfactory nature of the
environmental impact assessment supplied by Botnia . Particular attention is drawn to “gaps in
information, contradictions (even within the document) and vague and unsatisfactory replies” 443.
Despite the belief expressed by the Uruguayan authorities that the works are likely to cause serious
damage to the environment and therefore fall within the scope of Article 7, first paragraph, of the
Statute, they decided not to discharge their obligation to submit the project for examination by
CARU, the only body with competence to deal with the matter.
4.50. The Uruguayan actions were exactly the same as for the CMB project. The
Environment Ministry (MOVOTMA) authorized the construction of Orion without first going
through CARU as Article7 requires; Argentina, which had learned of the authorization through

the media, tried to consult CARU through its dele 444gation in order to ensure compliance with the
obligations arising under Chapter II of the Statute .
171 4.51. This behaviour on the part of Uruguay is all the more serious since Uruguay could not
have been unaware either of the dispute already caused by the authorization of the CMB project or
of its promise to return to CARU. Nor could it have been ignorant of the clear position taken by
Argentina on the need to comply with the procedur e prescribed in ChapterII of the 1975Statute.
Thus, when the issue of a meeting with represen tatives of Botnia was raised in CARU, “the
Argentine delegation stressed the importance of the consultation mechanism provided for by the
445
Statute of the River Uruguay” . The outgoing Uruguayan Government, just a few days before the
handover of power to President Vázquez, was fully aware that by granting Botnia authorization for
the Orion project on 14February2005, without going through CARU, it would aggravate the
dispute.
4.52. The position within CARU in that regard was manifestly clear: during the meeting of
11 March 2005, the President of the Argentine delega tion aired his concerns at the fact that he had
learned through the media that Uruguay had apparently authorized Botnia to construct another pulp
mill on the River Uruguay without going through CARU, despite a request for information from
the Commission to that end. Indeed, in a letter to DINAMA of 16November2004, CARU had
made it known that it had learned of the steps taken by Botnia to obtain an authorization to proceed
446
with construction and requ ested more information . The President of the Uruguayan delegation
personally confirmed at the meeting of 11March 2005 that, for his part, his delegation did not
know about the authorization, but that it was aware of the media articles about the plan referred to
447
by his Argentine colleague .
4.53. On 6May 2005 at CARU, the President of the Argentine delegation noted once more
that the mechanism for prior consultation (Articles 7 et seq.) prescribed in the Statute had not been
complied with for either the CMB or the Orion project. If the situation continued, he said,
172 Argentina would reserve t448right to set in train the procedures provided for in the Statute for the
settlement of disputes , namely conciliation or judicial settlement. The response from the
President of the Uruguayan delegation confirms the Argentine position; “the facts were as stated
449
by H.E. the Ambassador [García Moritán, President of the Argentine Delegation]” . This is a
further instance of Uruguay’s clear acknowledgmen t that it had failed to follow the mechanism
prescribed in Chapter II of the Statute.
4.54. To this day, despite repeated requests by Argentina both before and after the
authorization was granted to Botnia, CARU has still not been consulted on the project and Uruguay
still refuses to consult it in that regard.

C. The authorization for Botnia to construct the port terminal (5 July 2005)
4.55. When giving the Botnia company author ization on 5July2005 to utilize the riverbed
and construct a port for the exclusive use of the Orion mill, without consulting CARU, the
Uruguayan Government behaved exactly as for th e CMB and Orion mills. Once again Argentina
learned of the project through the Uruguayan media and formally requested the Uruguayan
Government to comply with the obligation prescrib ed in Article7 of the 1975 Statute by a Not450
dated 27June2005, in other words before Uruguay had issued the authorization . Once that
authorization had been granted, the Argentine re quest was officially reiterated at CARU on two
occasions, a451mpanied by a request to suspend work until CARU had made a determination on
the project .
4.56. The Uruguayan authorization of 5July2005 includes utilization by Botnia of the
173 riverbed and the right to fill the bed, construct a nd operate the port terminal and carry out dredging
work “essential to the port installations in orde r to allow ships to come alongside and manoeuvre,
452
and to maintain and keep the ac cess channel to the terminal open” . Clearly, works with such
features are among the various kinds referred to in Article7 of the 1975 Statute, in particular the
construction of new channels or any other works wh ich are liable to affect navigation, the régime
of the river or the quality of its waters.
4.57. Uruguay authorized the construction of the works, the utilization and filling of the
riverbed its filling and the construction and maintenance of a new channel before consulting CARU
in accordance with the mechanism for prior not ification and consultation provided for in the
Statute. This is not only flagrantly in conflict with the provisions of the 1975 Statute but also with
the procedure followed for Port M’Bopicuá, where construction commenced after CARU had taken
the decision that the works would not cause significant damage 453. For that reason, the Argentine
delegation requested that the works on the Bot454 port should be suspended pending a decision by
CARU, a request which Uruguay declined .
4.58. By authorizing Botnia to construct the Orion port, to utilize and fill the riverbed and
construct and maintain a channel before even consulting CARU, Uruguay violated the obligation
prescribed in Article 7 of the 1975 Statute.
D. The authorization for commissioning of the Botnia port terminal (24 August 2006)
4.59. The authorization for commissioning of the Botnia port terminal was given on
24August2006 by a resolution of DINAMA. Uruguay informed the Argentine delegation to
174 CARU of that authorization after the event; the President of the Uruguayan delegation merely
stated that she was “at the disposal of the Argen tine delegation to explain any points of uncertainty
or forward any additional inform ation it may consider relevant” 455. The port terminal is now

456
operational . Argentina protested at its commissioning, stating that this conflicted with the
provisions of the 1975 Statute, and asked Uruguay to suspend the commissioning of the terminal 457.
4.60. Since the authorization for commissioning of the Botnia port terminal was issued
without CARU being consulted, it constitutes a br each of Article7 of the 1975 Statute on the
grounds that it relates to an activity which is liable to affect navigation of the river.
E.The authorization for Botnia to extr act and use water from the River Uruguay
(12 September 2006)
4.61. Continuing with its systematic policy of unilateral authorizations, on
12 September 2006 Uruguay authorized Botnia to ex tract and use the waters of the River Uruguay
458
for industrial purposes, namely the production of pulp . On 17October2006, the Uruguayan
delegation forwarded the text of the resolution to CARU.
4.62. Article 27 of the 1975 Statute states in that regard:
“The right of each Party to use the waters of the river, within its jurisdiction, for
domestic, sanitary, industrial and agricu ltural purposes shall be exercised without
prejudice to the application of the procedure laid down in articles 7 to 12 when the use
is liable to affect the régime of the river or the quality of its waters.”
It is clear from the wording of Article 27 that that Article is not a “licence to pollute”, and that it in
175
no way precludes the Parties from following “the pro cedure laid down in Articles 7 to 12” before
every first use.
4.63. The authorization granted (until 30 June 2011) provides for the extraction and use of a
maximum of 60,000,000 m of water per annum or at a flow rate of 1,900 litres per second without
459
exceeding the maximum volume . This is indisputably a use which is liable to affect the régime
of the river or the quality of its waters 46. Uruguay was required to follow the procedure prescribed
in Articles 7 to 12 of the 1975 Statute and did not do so.
4.64. On a more general point, it should be noted that Uruguay can in no way rely on
Article27 in order to exonerate itself from its obligations under the 1975 Statute, as it did during
the hearings on the provisional measures requested by Argentina. On that occasion it claimed, for
example, that Article27 of the Sta461e “expressl y permits both Uruguay and Argentina to use the
river for industrial purposes” and that that Article “recognizes the right of each Party to exploit
the waters of the river for domestic, san itary, industrial and agricultural purposes” 462. Neither of
those statements is, of course, disputed; but it is unacceptable to infer as a result, as Uruguay has

done, that Article27 could have the effect of exonerating it from performing obligations that are
imposed by other provisions of the Statute.
176
Section II
Uruguay has failed to notify projects through CARU
(Article 7, second and third paragraphs)
4.65. After being consulted by the party which plans to carry out or authorize the
construction of works liable to affect the navigatio n, the régime of the River or the quality of its
waters, CARU has 30 days to respond. If it finds that the plan might cause significant damage to
the other party or if no decision can be reached, the party concerned is to notify the plan to the
other party through CARU. The third paragraph of Article7 reads: “Such notification shall
describe the main aspects of the wo rk and, where appropriate, how it is to be carried out and shall
include any other technical data that will enable the notified Party to assess the probable impact of
such works on navigation, the régime of the river or the quality of its waters.”
4.66. Evidently the fact that Uruguay failed to submit the pulp mill plans to CARU does not
mean it has the right to release itself from this second obligation, otherwise commission of the first
breach described would enable a party to exon erate itself at little cost from all subsequent
obligations prescribed in Articles7 et seq. of the Statute, and that cannot be allowed. Uruguay
authorized the construction of the contested mills without discharging the subsequent obligation to
notify the other party through CARU and to su pply it with the information required under
Articles 7 and 8 of the 1975 Statute.
A. Information on the CMB plan
4.67. At the hearing of 8 June 2006, Uruguay pleaded that it had discharged the obligation to
inform CARU, which had asked for and received “substantial and detailed additional information
regarding the mill” 46. The truth of the situation is that on 17October2002, once it had
unofficially learned of the CMB plan, CARU sought information from Uruguay’s Ministry of
177
Housing, Land Use Planning a nd Environmental Affairs (MOVOT MA), and received no reply.
CARU reiterated its request on 21 April 2003. The information forwarded by DINAMA to CARU
on 14May2003 related only to information alre ady available on its internet site, and nothing
464
more . On 15 August 2003 the President of CARU, Mr. Belvisi (Uruguay), wrote to his Minister
to inform him of the need for further information 465. Despite these repeated requests, instead of
sending the information sought, DINAMA directly gr anted the initial environmental authorization
on 9 October 2003, without going through CARU.
4.68. Uruguay also referred to a public hearing held in466ay Bentos, during which it claims to
have “officially disclosed th e information on the project” . Nonetheless, contrary to the claims
submitted by Uruguay, no delegate from CARU was involved in those meetings; only its technical
secretary and a “consultant” from CARU were present, and they reported on the discussions which

took place there 46. Moreover, even if some CARU delegates had been present and had
subsequently informed CARU, that would still not be what the Statute requires. CARU members
participate regularly in meetings of a very diverse nature to which they are invited, whether in their
capacity as CARU members or otherwise. Uruguay cannot seriously claim that the fact that two
members of CARU may have been involved in a public information meeting on the plan, which
was not the case, amounts to performance of the ob ligation incumbent on a State to inform CARU
in accordance with Article7, or even that it can in any way be linked to the mechanism for prior
notification and consultation provided for in Chapter II of the 1975 Statute.
4.69. The explanation put forward by Uruguay to the Court during the hearings of 8and
9June2006 in support of its claim that it co mplied with the obligation to forward CARU
information concerning CMB is, moreover, clearly inconsistent with the position it adopted earlier:
178 to show that in its eyes, the authorization to construct the CMB mill did not fall within the scope of
CARU, Uruguay supposedly chose to forward in formation directly to Argentina through its
Embassy in Montevideo. The fact that it was Ar gentina rather than Uruguay that forwarded that
information to CARU inFebruary2004 was due pr ecisely to the refusal by Uruguay to discharge
its obligation. Similarly the fact that, in the li ght of Uruguay’s breach of its obligation, Argentina
had to forward the file to CARU in no way excu ses that breach by Uruguay, nor does it imply any
agreement whatever on a change in procedure. On the contrary, the situation, which is remarkable
to say the least, is proof of Uruguay’s flagrant breach of its obligation to provide information
through CARU. Furthermore, in his letter accompanying the file supplied by Uruguay, the
President of the Argentine delegation asks for the relevant information to be sent to the
Sub-Committee on Water Quality, so that an assessme nt can be made of the extent to which the
planned works and their operation may affect th e quality of the waters of the River Uruguay,
“without prejudice to the considerations formulated in relation to Article7 of the Statute of the
River Uruguay by the Argentine delegation at the extraordinary plenary meeting of
468
17 October 2003” .
4.70. Indeed, as practice shows, referral to the relevant sub-committee is the preliminary step
469
to decision making at plenary meetings of the Commission . Clearly, Argentina reserved its
position with regard both to Uruguay’s breach of th e obligations to provide information and give
notification under Articles 7 and 8 of the Statute and to the duty on Uruguay, which still stands, to
comply with those obligations.
B. Information on the Orion mill
179
4.71. During the hearing of 8 June 2006, Ur uguay went through the same exercise as for the
CMB plan by explaining that it had also complied with its obligations in respect of the Orion mill.
In so doing, Uruguay stated that representatives of the Botnia company met CARU and provided
information, that members of CARU travelled to Finland and Spain to visit Botnia and ENCE
mills, and that CARU “organized a meeting” with representatives of Botnia on 19 October 2004 47.
In point of fact, although there were contacts between the companies and CARU, the only thing
this shows is that CARU regarded itself as competent to deal with the plans in question. However,
those contacts were purely preliminary in natu re and could in no way whatever supplant the
procedure set out in ChapterII of the 1975 Statute. On the contrary, these communications with

47CR 2006/47, pp. 39-40, para. 18 (Condorelli). - 108 -
CARU constitute additional evid ence of the need to submit those plans to the Commission, in
contrast to the conduct of Uruguay and its pleadings.
4.72. Uruguay has never given the require d information to CARU. The information
subsequently forwarded to Argentina concerning Or ion was communicated solely in the context of
the High-Level Group (GTAN) proceedings and proved to be manifestly incomplete 471.
C.Uruguay has expressly acknowledged that it failed to supply information to CARU in
accordance with the 1975 Statute
4.73. During the official presentation of the Uruguayan position by the Presidency of
180 Uruguay on 29May2006, it fell to AmbassadorFelip e Paolillo to set out the legal aspects of the
dispute with Argentina. He explained that:
“Uruguay informed the Argentine authorities of the projects and the
construction of works and on several occasions furnished the information requested by
the Argentine authorities. However, it did not do so through the procedure
established in the Statute of the River Uruguay. Why was this? Because authorities at
the highest level in both nations, namely the Ministers for Foreign Affairs in the one
case and the Presidents of the two countries in the other, had reached an agreement on
472
other alternative procedures.”
4.74. At the end of that official presentation, the Uruguayan Minister for Foreign Affa473
stated that the speakers “had summarized the exact Uruguayan position in 40 minutes” .
4.75. Ambassador Paolillo’s explanati on calls for comment on several counts. First, it
includes an express acknowledgment, devoid of an y ambiguity, that Uruguay did not forward the
information requested “through the procedure estab lished in the Statute of the River Uruguay”.
Secondly, the Parties never reached an agreement to follow procedures which were not those
established in the 1975 Statute, much less decide to suspend the application of Chapter II thereof.
Thirdly, the statement that Uruguay forwarded all info rmation requested to Argentina is clearly
refuted by the facts.
D. The information forwarded by Uruguay was and remains incomplete
4.76. The obligation incumbent on the Parties under the Statute is to forward all relevant
181 information. The distinguishing feature of the obligation concerning prior notification and
consultation is its purpose, whic h is to allow the other Party concerned “to assess the probable
impact of such works on navigation, the régime of the River or the quality of its waters” (Art.7,
third para.). It is therefore necessary to supply not just a few pieces of information, but full and
exhaustive details which enable such an assessment to be made in an effective way.

4.77. It is not correct to state, as Ambassador Paolillo did, that Uruguay forwarded Argentina
all the information it requested. The minutes of th e first meeting of the GTAN and the final report
of the Argentine delegation to that Group provid e a specific summary of the information requested
by Argentina which Uruguay failed to forward 47.
4.78. The Hatfield Report of 27March2006 recognized that the information on the CMB
and Orion mills was insufficient: “Assertions that the CIS, Botnia and CMB have not provided
sufficient information on the proposed design, op erating procedures and environmental monitoring
475
for the mills are generally valid” ; moreover, this comes over two years after the authorization
granted for the CMB mill and more than one year after the authorization for Botnia. Nothing that
has happened subsequently has changed that situation.
4.79. By failing to forward to CARU the info rmation needed for CARU and Argentina to be
able to make an assessment of the impact of th e planned works on the river and the areas affected
by it, Uruguay was in breach of the internationa l obligation incumbent on it under Articles 7 and 8
of the 1975 Statute.

The contested authorizations were issued by Uruguay despite opposition from
Argentina and despite the absence of a settlement to the dispute (Article 9)
4.80. Uruguay has failed both to consult CARU on all the disputed plans for works or uses of
the river (construction of the CMB and Orion mills and the Botnia port, commissioning of that port
and extraction and use of river water by Botnia ) and to forward the necessary information on the
two mills, but furthermore it authorized those works and uses of the river despite Argentine
objections and despite the absence of a settlement of the dispute between the two countries. This is
blatantly inconsistent with the procedure prescr ibed in ChapterII of the 1975 Statute, which
provides that the Party concerned may ca rry out or authorize the work planned if CARU expressly
decides that the works will not cause significant dama ge to the other Party (Art. 7, first and second
paragraphs), or if the latter Party reaches the sa me conclusion or does not respond after receiving
the relevant information (Art. 9). In the event of a dispute arising between the Parties in that regard
which cannot be resolved, it is for the Court to resolve it (Art. 12). As was explained in Chapter III
of the Memorial, as long as no decision in favour of the construction or the authorization to proceed
with the construction is made, the Party concerned may not take unilateral action to that effect.
4.81. If Uruguay is to be believed, the Statut e places the Parties under an obligation merely
to provide information, and the Parties are in sole control of their decisions. ChapterII is clear,
however: first, CARU, as a bi-national body, mu st be consulted on the matter; then the Party
concerned must first supply CARU ⎯ and where necessary the other Party, through CARU ⎯ with
183 information in accordance with the provisions of the Statute. Finally, the Party which has been

notified and duly informed has the right to assess the plan and to respond through CARU on its
476
compatibility with the Statute. As was explained in ChapterIII of the Memorial , the other
Party’s point of view is not simply an opinion: either there is agreement between the Parties,
whether in CARU or directly, and the plan can be authorized and the works carried out; or there is
a dispute which must be resolved either by direct negotiations or by a judicial settlement through
the International Court of Justice.
4.82. This breach of Article 9 goes hand in hand with and is the consequence of the breach of
the first paragraph of Article 7, but is noneth eless distinct from it: Uruguay should not only have
informed CARU first ⎯ and if necessary Argentina, through CARU ⎯ of the plans, but should
also have refrained from authorizing the works for as long as the procedure had not reached a
conclusion and until such time as all the competent bodies had responded to the plan. This is an
477
obligation of result .
4.83. Having regard to the conduct of Uruguay and the information available, Argentina has
consistently expressed its disagreement with the construction of the CMB and Orion mills and the
Orion port, the commissioning of that port and th e extraction and use of river water by Botnia 47.
Despite those protests, despite the fact that the Pa rties had entered into direct negotiations with a
view to resolving the dispute, and despite its submission to the Court by Argentina in accordance
with the 1975 Statute, Uruguay has issued the auth orizations to carry out the works and utilize the
waters and the riverbed without waiting for a decision from CARU, a direct settlement, or
settlement by the Court, as provided for in th e 1975 Statute. Thus Uruguay has committed a
number of internationally wrongful acts.
184 Section IV
The conduct of Uruguay constitutes a material breach of the 1975 Statute
4.84. Uruguay’s repeated conduct is evidence of a systematic repudiation of the Statute of
the River Uruguay. Indeed, fromOctober2003 to date, each time Uruguay has found itself in a
situation where it was required to apply the procedure prescribed in Chapter II of the 1975 Statute,
it has systematically chosen not to do so. Th at conduct constitutes a material breach of the
1975Statute within the meaning of Article60 of the Vienna Convention on the Law of Treaties
479
which sets out the situation with regard to customary law on the subject .
4.85. Indeed, pursuant to Article 60 (3) of that Convention,
“A material breach of a treaty, for the purposes of this article, consists in:
(a) a repudiation of the treaty not sanctioned by the present Convention; or
(b)the violation of a provision essential to the accomplishment of the object or
purpose of the treaty.”

See CR 2006/46 (Pellet), p. 60, para. 12 (2nd indent).

4.86. In the present case, each of these forms of a material breach has occurred. Firstly,
Uruguay’s ongoing conduct and the explanations of the Minister for Foreign Affairs, Mr.Opertti,
and the President of the Uruguayan delegation to CARU, MsPetrocelli, to the Uruguayan Senate
are clear evidence of a repudiation of the treaty concerned 48. They embody a stance the purpose of
185 which is to release Uruguay from the obligations ar ising under the 1975 Statute for reasons which
are not recognized either in the Statute itself or in the law of treaties 48.
4.87. Secondly, the procedure prescribed in Chapter II unquestionably constitutes a provision
essential to the accomplishment of the object and purpose of the 1975 Statute. Without a procedure
482
for notification and consultation, that treaty would lose its essential thrust . As the Court has
noted, “the procedural mechanism put in place under the 1975 Statute constitutes a very important
part of that treaty régime” 483. By its conduct, Uruguay has systematically committed a serious
material breach of provisions essential to the accomplishment of the object and purpose of the
1975 Statute.
4.88. Argentina wishes to point out that although the breaches committed by Uruguay of the
provisions of the 1975 Statute are “material” w ithin the meaning of Article60 of the Vienna
Convention on the Law of Treaties, the Statute has in no way been terminated and its operation has
not been484spended. Those breaches, which fall w ithin the law of responsibility and not the law of
treaties , entail the international responsibility of Uruguay with all the consequences that implies.
4.89. In conclusion, it would appear that:
(a) By authorizing the construction of CMB on 9 October2003, Uruguay violated the obligation
incumbent on it to comply with the procedure pr escribed in ChapterII of the 1975 Statute, in
particular:
(i) the obligation to consult CARU;
(ii) the obligation to provide CARU with the information requested;
186 (iii) the obligation to notify Argentina of the project through CARU;
(iv) the obligation to reach an agreement with the other Party or to await settlement of the
dispute in accordance with the procedure pr escribed in ChapterII of the 1975 Statute,
before authorizing the construction of the CMB mill.
(b) By authorizing the construction of Orion on 14 February 2005, Uruguay violated the obligation
incumbent on it to comply with the procedure pr escribed in ChapterII of the 1975 Statute, in
particular:
(i) the obligation to consult CARU;
(ii) the obligation to provide CARU with the information requested;

Chapter II of the 1975 Statute, in particular:
(i) the obligation to consult CARU;
(ii) the obligation to provide CARU with the information requested;

dispute in accordance with the procedure pr escribed in ChapterII of the 1975 Statute,
before granting that authorization.
(e) All those authorizations, and the obstinate refu sal on the part of Uruguay to submit to the
procedure prescribed in ChapterII of the 1975 Statute, constitute a material breach of that
Statute, which entails the responsibility of Uruguay. - 113 -
CHAPTER V
B REACHES BY U RUGUAY OF MATERIAL OBLIGATIONS
5.1. The previous Chapter described the br eaches by Uruguay of the obligations incumbent
191
upon it pursuant to Chapter II of the 1975 Statute. This Chapter describes the breaches by Uruguay
of the other obligations incumbent on it pursuant to the 1975 Statute. The two categories of breach
are closely linked.
5.2. The 1975 Statute neither provides for nor implies any hierarchy among the rules and the
obligations it lays down. The obligations are often interlinked, even though breaches of them
constitute distinct internationally wrongful acts. The same is true of the two categories of
obligation imposed on the Parties by the Statute: material obligations to prevent pollution and
other damage to the River Uruguay (which can be regarded as obligations of result) on the one
hand; procedural obligations of co-operation, prior notification and consultation (which have
similarities to obligations of conduct) on theother, the latter constituting the means of achieving
the results envisaged by the former. These are inte grated obligations which together contribute to
achieving the objective of the Statute as set out in Article1, namely “to establish the joint
machinery” ⎯ which relates to procedural obligations ⎯ “necessary for the optimum and rational
utilization of the River Uruguay, in strict observance of the rights and obligations arising from
treaties and other international agreemen ts in force for each of the Parties”⎯ which relates to
“material” obligations.
5.3. In this chapter, we will show that Ur uguay has systematically violated the obligations
incumbent on it pursuant to the 1975 Statute in order to authorize construction and future
commissioning 48. The breaching by Uruguay of the obliga tion to prevent pollution and to protect
the quality of the waters of the River Uruguay and its ecosystem will first be established by
demonstrating: that Uruguay has systematically failed to take the measures necessary to protect the
quality of the waters of the Rive r Uruguay and its ecosystem; that Uruguay decided not to ensure
that a complete environmental impact assessment was produced; and that it neglected to take
192
appropriate measures to prevent pollution, firstly by failing to comply with the obligations of prior
notification and consultation incumbent on it under Chapter II of the 1975 Statute, and secondly by
authorizing the construction of the Orion mill at an inappropriate site and neglecting to make it a
requirement that the mill should employ the best available techniqu es and follow the best
international practice. It will then be demonstrated that Uruguay has failed to comply with its
obligation to take the measures necessary to preven t any significant damage to the régime of the
River Uruguay or the quality of its waters, and that Uruguay has violated its obligation to avoid any
change in the ecological balance in the river a nd the areas affected by it, as well as the obligation
not to cause a significant adverse transboundary impact.
Section I
Introductory remarks
5.4. By way of introduction, Argentina would like to make it clear that the principle of
sustainable development applies as part of the 1975 Statute and that it does not in any circumstance
allow Uruguay not to comply with the provisions of the 1975 Statute. Argentina notes also that the
principle of permanent sovereignty over natural res ources, in the case of a shared resource such as
485
As regards the CMB plan, see paras. 0.17 and 4.2 above. - 114 -
the River Uruguay, must be applied in keeping w ith the obligations prescribed in the 1975 Statute,
and that the Statute must be interpreted a nd implemented in accordance with the rules and
principles of international law that are applicab le to the present case, including the precautionary
principle.
A. The principle of “sustainable development” applies to the 1975 Statute and does not allow
Uruguay not to comply with its obligations
5.5. The concept of “sustainable development” requires Uruguay and Argentina to deal with
the objectives of environmental protection and econom ic development in an integrated fashion.
That approach is reflected in many international instruments, including several provisions of the
Rio Declaration on Environment and Development of 1992. Principle 3 thereof states that “the
193
right to development must be fulfilled so as to equitably meet developmental and environmental
needs of present and future generations” (emphasis added). Principle 4 of the declaration adds that:
“in order to achieve sustainable development, environmental protection shall constitute an integral
part of the development process and cannot be considered in isolation from it” (emphasis added).
5.6. Under the principle of sustainable development, States fulfil their right to development
while complying with the obligations incumbent on them as regards the promotion and protection
of the environment. This includes the obligations arising out of the 1975 Statute and the
obligations to which that Statute refers. In its Judgment in the case concerning the
Gabčíkovo-Nagymaros Project, the International Court of Justice noted the need for reconciliation:
“Throughout the ages, mankind has, for economic and other reasons, constantly
interfered with nature. In the past, this was often done without consideration of the
effects upon the environment. Owing to new scientific insights and to a growing
awareness of the risks for mankind ⎯ for present and future generations ⎯ of pursuit
of such interventions at an unconsidered and unabated pace, new norms and standards
have been developed, set forth in a great number of instruments during the last two
decades. Such new norms have to be taken into consideration, and such new standards
given proper weight, not only when States contemplate new activities but also when
continuing with activities begun in the past. This need to reconcile economic
development with protection of the environm ent is aptly expressed in the concept of
486
sustainable development.”
5.7. The concept of “sustainable developmen t” cannot be relied upon to justify giving the
objectives of economic development any priority over essential environmental needs. Uruguay has
acknowledged that its “sovereign right to implem ent a sustainable economi c development project
in its own territory” must not violate “obligations under the Statute, or the anti-pollution standards
194 of the CARU, which were jointly de veloped by Uruguay and Argentina” 487. The 1975 Statute is
closely bound up with the principle of sustaina ble development, and Uruguay cannot properly rely
on that principle as a ground for not complying with the obligations incumbent on it under the
Statute.
5.8. In practice, this means that the two objectives of environmental protection and economic
development must be implemented in a balanced way, with neither having supremacy over the
other. That principle was reaffirmed by the Arbitral Tribunal in the “Iron Rhine” Arbitration:
48Gabčíkovo-Nagymaros Project (Hungary/Slovakia), op. cit., p. 78, para. 140; emphasis added.
487
CR 2006/47, para. 51 (Reichler). - 115 -
“Since the Stockholm Conference on the Environment in 1972 there has been a
marked development of international law relating to the protection of the environment.
Today, both international and EC law re quire the integration of appropriate
environmental measures in the design and implementation of economic development
activities. Principle 4 of the Rio Declaration on Environment and Development,
adopted in 1992 (31 I.L.M. p.874, at p.877), which reflects this trend, provides that
‘environmental protection shall constitute an integral part of the development process
and cannot be considered in isolation from it’. Importantly, these emerging principles
now integrate environmental protection into the development process. Environmental
law and the law on development stand not as alternatives but as mutually reinforcing,
integral concepts, which require that wh ere development may cause significant harm
to the environment there is a duty to preven t, or at least mitigate, such harm (see
paragraph 222). This duty, in the opinion of the Tribunal, has now become a principle
of general international law. This princi ple applies not only in autonomous activities
but also in activities undertaken in implem entation of specific treaties between the
488
Parties.”
The Arbitral Tribunal recognized that “[t]he mere invocation of such matters does not, of course,
provide the answers in this arbitration to what may or may not be done, where, by whom and at
489
195 whose costs” . The Tribunal therefore analysed in de tail the manner by which those principles
were to be applied to the case submitted to it, and stated in paragraphs 222 and 223 of its award:
“The use of the Iron Rhine railway started some 120 years ago and it is now
envisaged and requested by Belgium at a subs tantially increased and intensified level.
Such new use is susceptible of having an adverse impact on the environment and
causing harm to it. Today, in internationa l environmental law, a growing emphasis is
being put on the duty of prevention. Much of international environmental law has
been formulated by reference to the impact that activities in one territory may have on
the territory of another. The Internationa l Court of Justice expressed the view that
‘[t]he existence of the general obligation of St ates to ensure that activities within their
jurisdiction and control respect the environment of other States or of areas beyond
national control is now part of the cor pus of international law relating to the
environment’ (Legality of the Threat or Use of Nuclear Weapons , Advisory Opinion,
I.C.J. Reports 1996 (I), p. 226 at pp. 241–242, para. 29).
Applying the principles of internati onal environmental law, the Tribunal
observes that it is faced, in the instant case, not with a situation of a transboundary
effect of the economic activity in the territo ry of one state on the territory of another
state, but with the effect of the exercise of a treaty-guaranteed right of one state in the
territory of another state and a possible impa ct of such exercise on the territory of the
latter state. The Tribunal is of the view that, by analogy, where a state exercises a
right under international law within the terr itory of another state, considerations of
environmental protection also apply. The exercise of Belgium’s right of transit, as it
has formulated its request, thus may well necessitate measures by the Netherlands to
protect the environment to which Belgium will have to contribute as an integral
element of its request. The reactivation of the Iron Rhine railway cannot be viewed in
isolation from the environmental protection measures necessitated by the intended use
of the railway line. These measures are to be fully integrated into the project and its
costs.”

5.9. The Tribunal’s approach to the application of the principles of international
environmental law, especially the principle of sust ainable development, is relevant to the present
case: indeed it relates to the issue of “a tran sboundary effect of the economic activity in the
territory of one state on the territory of another stat e”. In such a situation, measures to protect the
environment must, in the words of the Tribunal, “be fully integrated into the project and its costs”.
196 In the present case, the solution means that the envi ronmental considerations needed to form an
integral part of Uruguay’s decision-making process in respect of the launching of the Orion project
and that such considerations were not to arise afte r the event. In accordance with the principle of
490
sustainable development, no decision relating to the Orion project (or the CMB project) could or
should have been taken by Uruguay before all th e environmental consequences had been studied
and taken into consideration. Argen tina has shown in Chapters II and IV 491that it was nothing of
the sort: Uruguay authorized the project, not only in violation of the 1975 Statute, but also before
all the environmental consequences of the projec t had been established. That approach is
incompatible with the standards associated with the concept of su stainable development, a crucial
element of the framework put in place by the 1975 Statute governing a shared natural resource.
B. The principle of permanent sovereignty over natural resources must be applied in keeping
with the obligations prescribed in the 1975 Statute
5.10. The same approach must be applied to the principle of permanent sovereignty over
natural resources. That principle must be interpre ted in the context of general international law,
particularly in view of the limits to the exer cise of sovereignty arising from the international
principles of environmental protection and sustai nable development. The general restriction
imposed by environmental standards is reflected by Principle 21 of the Stockholm Declaration and
Principle 2 of the Rio Declaration of 1992. It is clear from both those declarations that, especially
by reason of the nature of the River Uruguay as a shared natural resource, Uruguay’s right to
exploit that resource cannot be fulfilled to the detriment of the obligation not to cause
environmental damage to Argentina. In its Advisory Opinion on the lawfulness of the threat or use
197
of nuclear weapons, the International Court of Justice noted the customary 492ure of that obligation
(also referred to by the Arbitral Tribunal in the Iron Rhine Arbitration) .
5.11. The 1975 Statute takes the obligations on Uruguay beyond customary law. The
principle of permanent sovereignt y over natural resources must be in terpreted in the light of the
treaty-based obligations subscribed to by Uruguay in the 1975 Statute. The principle of permanent
sovereignty over natural resources cannot be relied upon to modify rights and obligations which are
clearly prescribed in the 1975 Statute, whether in respect of the nature and extent of the obligations
to co-operate or the obligation to prevent po llution pursuant to the Statute. The 1975 Statute
“organizes” the exercise of permanent sovereignty over natural resources, in particular shared
resources such as the River Uruguay, in accordance w ith the general principle of sovereignty.
There is hardly any need to recall the words of the Permanent Court of International Justice:
“The Court declines to see in the conclusion of any Treaty by which a State
undertakes to perform or refrain from perform ing a particular act an abandonment of
its sovereignty. No doubt any convention creating an obligation of this kind places a
restriction upon the exercise of the sovereign rights of the State, in the sense that it
49Where the CMB project is concerned, see paras. 0.17 and 4.2.
491
See in particular Chap. IV, paras. 4.3-4.10.
492
See para. 5.8. above. See also Chap. III, paras. 3.189-3.192. - 117 -
requires them to be exercised in a certain way. But the right of entering into
493
international engagements is an attribute of State sovereignty.”
5.12. Uruguay cannot properly rely, in support of its argument concerning the principle of
permanent sovereignty over natural resource s, on paragraph3 of resolution2995 of
15 December 1972 of the General Assembly of the United Nations on Co-operation between States
in the field of the environment. In the initia l proceedings on provisional measures, Uruguay relied
on paragraph 3 of that resolution to support the argument that the 1975 Statute was to be read in the
198 light of the principle of permanent sovereignty over natural resources, thus restricting the rights
held by Argentina under the 1975 Statute. Uruguay’s reference to United Nations General
Assembly resolution 2995 is, however, devoid of subs tance. The resolution states that the General
Assembly
“2. Recognizes that co-operation between States in the field of the
environment... will be effectively achie ved if official and public knowledge is
provided of the technical data relating to the work to be carried out by States within
their national jurisdiction, with a view to avoiding significant harm that may occur in
the environment of the adjacent area;
3. Further recognizes that the technical data referred to in paragraph 2 above
will be given and received in the best sp irit of co-operation and good-neighbourliness,
without this being construed as enabling each State to delay or impede the
programmes and projects of exploration, e xploitation and development of the natural
resources of the States in whose territories such programmes and projects are carried
out.”
Paragraph 3 concerns only the supply of techni cal data voluntarily shared in the spirit of
paragraph 2. It does not relate to circumstances such as those in the presen t case, in which a State
has entered into a treaty-based obligation to co-operate in a specific way with a neighbouring State,
which includes inter alia a mechanism for prior consultation and exchange of information.
Paragraph 3 cannot be relied upon separately as a basis for interpreting the provisions of the
1975 Statute. The fact that its adoption occurred three years prior to that of the 1975 Statute clearly
shows that it can be of no relevance in the interp retation of the Statute, whose provisions are more
recent and must in any event be construed an d applied in accordance both with subsequent
developments in international law and with the ru le of specificity, whereby a specific rule must
take precedence over a general rule.
C.The 1975 Statute must be interpreted and implemented in accordance with the
199
precautionary principle
5.13. The Parties recognize that the 1975 Statute must be interpreted and applied in the light
of the precautionary principle as a rule of international law 49. It was also established in Chapter III
that the precautionary principle applies pursuant to Articles 1 and 41 (a) of the 1975 Statute, which
allow the obligations arising from international c onventions that are applicable to the present case
to be incorporated and applied 495. In that regard, two international instruments are of particular
significance: the Convention on Biological Diversity of 1992 and the POPs Convention of 2001;

495
See Chap. III, paras. 3.193-3.196. - 118 -
496
both require Uruguay to apply the precautionary principle . The precautionary principle is in
addition to the general requirements of “vigilance an d prevention” referred to by the International
Court of Justice in the case concerning the Gabčíkovo-Nagymaros Project 49.
5.14. The precautionary principle applies to environmental protection where there are
“threats of serious or irreversible damage” 498. It provides that “lack of full scientific certainty shall
not be used as a reason for postponing cost-e ffective measures to prevent environmental
degradation”. In the present case the precautionary principle, alongside the obligation to prevent
any damage to the environment, means that the parties to the 1975 Statute are required to notify
each other of all the probable environmental consequences of their actions which may cause serious
or irreversible damage before such actions are authorized or undertaken. The fact of authorizing
the construction or operation of a pulp mill before the procedure prescribed in an international
treaty (the 1975 Statute) has been completed, including the prior environmental impact assessment,
is incompatible with an approach based on the precautionary principle (and the existing obligation
to prevent pollution). A precautionary approach therefore requires the parties to the 1975 Statute to
200 comply with their obligations of notification and consultation before authorizing the construction or
commissioning of works.
5.15. The precautionary principle may also have an impact on the burden of proof. In the
words of a most eminent writer, “there are ex amples where application of the precautionary
principle has reversed the burden of proof of risk. Exceptionally in this form it becomes
impermissible to carry out an activ ity unless it can be shown that it will not cause unacceptable
harm to the environment.” 499 Argentina is therefore of the view that the 1975 Statute, like the
POPs Convention of 2001 (the preamble to wh ich acknowledges that “precaution . . . is embedded
within this Convention”), adopts an approach in terms of precaution whereby the burden of proof is
placed on Uruguay for it to establish that the Orion pulp mill will not cause significant damage to
the environment. Uruguay failed to establish the environmental consequences of its actions prior to
authorizing the Orion mill. It is shown in Chapter VII that Uruguay has still not assessed the
impact of the construction and operation of the Orion mill on the quality of the waters of the
RiverUruguay. In particular, Uruguay has failed to carry out the appropriate studies, or to have
such studies carried out, in order properly to understand the régime of the River Uruguay, the
impact of the phenomenon of reverse flow and the consequences of climate change. Uruguay
authorized the construction of the Orion mill w ithout having established in advance whether the
River Uruguay was capable of absorbing all the new pollutants which would be emitted over the
estimated 40-year lifetime of the mill. The same is true of the impact on the atmosphere.
Furthermore, Uruguay has wholly failed to study the consequences for air and water quality of a
possible accidental discharge of pollutants 500.
5.16. During the public hearings on the request for the indication of provisional measures,
201 ProfessorBoyle, on behalf of Uruguay, criticized the use by Argentina of the precautionary
501
principle in the dispute . The arguments put forward on that occasion display a complete
misunderstanding of the application of the precautionary principle in a case such as the present one.

5.17. Uruguay argued, first, that the precautionary principle did not apply, claiming that
there was no uncertainty about the environmental effects of the kraft technology, and that the
environmental impact studies were comprehensiv e and precise about the likely consequences of
each of the projects. Argentina contests that stat ement and refers to Chapter VII as a whole, where
the issue of the environmental impact of the Ori on mill (and the shortcomings in the impact study)
is discussed. ChapterVII refers to a number of areas of uncertainty, such as the implications of
reverse flow for the concentration of pollutants, wind direction, changes in climate and the likely
impact of the presence of pollutants on the fish in the river. Moreover, the impact of a project is
largely determined by the peculiar features of the environment which must experience the
consequences of that project, and it cannot theref ore be seriously contended that the use of a
particular technology at other sites (kraft technology, in the present case) means that all uncertainty
is forever laid to rest as far as its effects on th e river environment are concerned. That basic
principle is present in many international instruments concerning environmental impact
assessments, for example those of the World Bank or the European Union 50. Argentina refuses to
accept that the environmental impact assessment s ubmitted by Botnia is sufficiently specific and
detailed. And the position was not clarified in the Cumulative Impact Study (CIS), as confirmed by
the Hatfield report.
202 5.18. It is not, moreover (contrary to what Uruguay would seem to suggest), for Argentina to
state how the risks posed by the pulp mill are to be managed or for it to determine what the socially
acceptable level of risk would be. The 1975 Statut e and other relevant international instruments
provide a detailed legal framework for determining the steps Uruguay is (or is not) authorized to
take when there is scientific uncertainty as to the likely impact of the project on the environment of
the river and the environment in general, particul arly the areas affected by the river in Argentine
territory. That legal framework, especially Articl es7, 13, 27, 29 and 40 of the Statute, has been
referred to previously. Those provisions, taken t ogether, confirm that the objectives of the Statute,
in material as well as procedural terms, must be implemented as part of an approach aimed at
preventing any deterioration in the quality of the River Uruguay or in its régime. It is therefore for
Uruguay to demonstrate that its actions do not prejudi ce either the régime of the river or its waters
inside and outside its jurisdiction, and the Statute clearly provides that Uruguay does not have the
right to impose its views on Argentina or to take it upon itself to make a decision in respect of
which machinery has been provided for in a treaty.
5.19. Finally, Uruguay refers to the fact that the POPs Convention of 2001 (to which the
503
precautionary principle expressly applies) does not entirely prohibit persistent organic pollutants,
but merely regulates their use. In fact, the Convention prohibits the production, use and trading of
certain substances listed in AnnexA to the C onvention (subject to possible exemptions) and
significantly restricts the production and use of othe r substances listed in Annex B. The overall
objective of the Convention, which is set out in Article1, is to protect human health and the
environment from persistent organic pollutants. The fact that a given substance has not been
completely prohibited does not therefore mean, contrary to the argument put forward by Uruguay,
that its production or emission in a given situa tion automatically fulfils the requirements of the
precautionary principle. Furthermore, one of th e objectives of the POPs Convention is to reduce
502
The prime importance of taking the host environment of the project into consideration is clear from World
Bank Operational Policy No.4.01 (Ann.B). The text states that environmental impact studies specific to each project
must deal with the initial environmental conditions as they are at the time. European Union Council Directive 97/11/EC
of 3 March 1997 amending Directive 85/337/EEC requires the Member States to “adopt all measures necessary to ensure
that, before consent is given, proj ects likely to have significant ef fects on the environment by virtue, inter alia, of their
nature, size or location are made subject to a requirement for development consent and an assessment with regard to their
effects” (Art. 2 (1)).

and eliminate the dioxins and furans used in the production of pulp, and Uruguay accepts that it has
203 504
not provided for any means of reducing, let alone eliminating, those two substances .
Section II
Uruguay has violated its obligations to prevent pollution and protect
the quality of the waters of the River Uruguay and its ecosystem
5.20. Chapter X of the 1975 Statute is entitled “Po llution”. It contains four articles, two of
which are relevant for our purposes. Ar ticle40 defines pollution and Article41 (a) lays down
obligations to protect and preserve the aquatic environment and prevent its pollution.
5.21. As stated in Chapter III, the concept of pollution as set out in the 1975 Statute is very
broad. The two parties recognize that it excludes de minimis pollution, but dispute whether the
envisaged pulp production constitutes pollution within the meaning of the Statute.
5.22. Argentina’s position is clear. The defin ition of pollution contained in Article40 is
along the lines set out in many international agreemen ts and in keeping with international practice.
It sets a very low threshold and Argentina is of the view that all discharges other than those of
minimal volume are covered.
5.23. The objective of the 1975 Statute is to prevent any activity which is “liable to affect the
quality of [the] waters” of the River Uruguay. In its study of the impact of discharges from the
Orion mill, Uruguay is therefore required to prove, inter alia , that those discharges, whether
intentional or accidental, (1) do not constitute pollu tion and (2) will not be “liable to affect the
quality of [the] waters” of the River Uruguay. Ur uguay has hitherto been unable to do this. Its
inability in particular to take account of the effect s of low flow rates in the river, the impact of
increased levels of nutrients (especially phosphor us) on levels of eutrophication and the risks to
204 human health from bioaccumulation and bioamplifica tion of pollutants in fish stocks constitutes a
clear failure by Uruguay to fulfil its obligation to prevent pollution.
5.24. The anticipated discharges from the Orion mill therefore constitute “pollution” within
the meaning of Articles 40 and 41 and on that basis are “liable to affect the quality of [the] waters”.
This latter point is clear f505 the experts’ reports referred to in Chapter VII, especially the Wheater
and Latinoconsult reports .
5.25. Moreover, the obligation to prevent pollution of the River Uruguay does not relate
solely to protecting the aquatic environment per se but also extends to any other reasonable and
legitimate use of the waters of the river. Po llution of the river will harm tourism and other
activities, whether recreational in nature or of othe r kinds. The scope of the 1975 Statute is broad,
and covers all harmful situati ons indirectly resulting from pollution of the River Uruguay.
Uruguay has clearly taken an excessively bureaucr atic and narrow view of what the Statute is
seeking to protect. Uruguay claims that the Stat ute concerns only pollution of the river and that
506
consequently that issue alone falls within the jurisdiction of the Court . The intention behind the
resulting approach appears to be to exclude from consideration by the Court all the economic and

506
CR 2006/49, paras. 3-4 (Boyle), and paras. 7-8 (Condorelli). - 121 -
social consequences (including tourism-related activities) which the pollution of the river would
entail. Argentina reaffirms that that argument is wholly without foundation. It is, moreover,
incompatible with the approach pr evailing in general international law: the draft Articles of the
International Law Commission on Prevention of Transboundary Harm from Hazardous Activities
state that “harm” means “harm caused to pers ons, property or the environment” (Art.2 (b)).
Tourism is a particularly telling example in this regard. Tourism-related activity on the Argentine
bank of the River Uruguay occurs there precisely b ecause that is where the river is. Without the
river, there would no longer be any beaches, fish ing or pleasure sailing. Actual pollution of
bathing areas and the (justified) fear of river polluti on will in all likelihood result in the decline or
205 disappearance of tourism 507. The link between clean water and tourism is well established, as is
shown in the Berlin Declaration on Biological Di versity and Sustainable Tourism adopted in 1997
508
at an international conference of Ministers for the Environment . Article 42 of the 1975 Statute
sets out the principle of responsibility for damage caused by pollution. It follows from recognized
principles of international law that responsibility for harm linked to the pollution of a river includes
indirect harm which adversely affects economic activities ⎯ especially tourism-related
activities ⎯ which are directly affected by the pollution of the river.
5.26. In short, discharges from the mill do i ndeed constitute pollution within the meaning of
Articles40 and 41 of the Statute. They are “liable to affect... the quality of its waters”. The
authorization of discharges by Uruguay must be assessed in the light not only of their direct effects
on the aquatic environment but also their impact on all legitimate uses of the river, especially
tourism 509. The quality of the waters includes the river’s ecosystem and the areas affected by it as a
whole, including wetlands and other biological divers ity, and covers all areas likely to be affected
510
by the phenomenon of reverse flow .
5.2ti.cle (a) of the Statute commits the parties to: “protect and preserve the aquatic
environment and, in particular, to prevent its pollution, by prescribing appropriate rules and
measures in accordance with applicable internationa l agreements and in keeping, where relevant,
with the guidelines and recommendations of international technical bodies”.
5.28. It was shown in Chapter III that the provisions of Article41 (a) point to a twofold
206 operation: firstly, the text places the parties under a general obligation to “protect and preserve the
aquatic environment”; secondly, it places the parties under a special obligation “to prevent [the]
pollution [of the River Uruguay]”. These measures must also be in accordance with applicable
international agreements and in keeping w ith the guidelines and recommendations of the
international technical bodies, also identified in Chapter III.
5.29t.cle (a) places Uruguay under obligations which are directly applicable to the
decisions on the Orion mill. In the event th at Uruguay fails to prescribe all the appropriate
measures to prevent pollution of the River Uruguay by the pulp mill, it puts itself in clear breach of
the obligations incumbent on it under Article41 (a). Argentina reaffirms that Uruguay has not
adopted the appropriate measures. In particular, Uruguay has failed to prescribe measures to:
(i) protect the quality of the waters of the River Uruguay and the areas affected by it;
50See paras. 7.195-7.204.
50Http://www.gdrc.org/uem/eco-tour/berlin.html.

(navigation).
51See in particular Chap. VII, paras. 7.50-7.65 (aquatic life and biological diversity) and paras. 7.46-7.61. - 122 -
(ii) protect and preserve the biological diversity of the River Uruguay and the areas affected
by it and the biological diversity dependent on it;
(iii) have a full and objective environmental im pact assessment carried out before making the
decision to authorize the mill;
(iv)ensure the participation of Argentina, as provided for in the 1975 Statute, by means
including the exchange of information, prior notification and consultation;
(v) authorize the project only if sited in an appropriate location from an environmental point
of view;
(vi)require the mill project to employ “the best available techniques” and “the best
environmental practices” for the purposes of its assessment.
A.Uruguay has failed to adopt all measures to protect the quality of the waters of the
River Uruguay and the areas affected by it
5.30. Protection of water quality is at the heart of this case. It is shown in Chapter VII that
even though the waters of the River Uruguay post good results today in certain fields, they already
207 have high levels of pollutant concentration (e.g. of phosphorus). This means that Argentina and
Uruguay have a particularly important joint respon sibility in maintaining protection of the quality
of these waters.
5.31. Moreover, that responsibility is acute. In view of this, Argentina was extremely
concerned to see Uruguay deciding to authorize, unilaterally, in breach of the 1975 Statute, the
construction of the Orion mill, which is designed to discharge large quantities of liquid effluent
directly into the River Uruguay over a period of at least 40 years, particularly since there are no
other pulp mills on the River Uruguay, and no ot her industrial installation discharges even a
fraction of the volume of the liquid pollutants anticipated for the Orion mill. The mill therefore
represents a unique and serious threat to the river waters. Uruguay’s decisions threaten to change
radically the quality of the waters of the river. Argentina was therefore entitled to expect that
Uruguay would conduct the appropriate studies to ensu re that the quality of the waters would be
maintained despite the anticipat ed discharges and, moreover, that Uruguay would do so before
performing its procedural obligations under th e 1975 Statute and before authorizing the
construction of the mills. If it had wished to fulfil the obligations incumbent on it under the
Statute, especially Article41 (a), Uruguay should have taken three steps to comply with the
511
requirements of due diligence and its obligation to prevent damage to the environment, namely :
(1)establish the initial quality of the waters recei ving the pollutants, (2)identify as clearly as
possible the volume and characteristics of the polluta nts which the mill will have to discharge into
the river and (3) establish that the waters receivi ng the anticipated polluting discharges are able to
receive them and then disperse them in such a way as to prevent any harm. Uruguay has not
pursued any of those measures in a way which woul d have enabled it to establish that water quality
would be protected.
5.32. As regards the initial quality of the waters, it is perfectly clear that a certain number of
pollutants are already present at very high levels. It is shown in Chapter VII that there is already a
208 relatively high level of phosphorus (P) in the River Uruguay. That situation is of great concern and
poses a potential risk of both eutrophication and an in crease in the proliferation of aquatic flora, as
511
See Chap. VII, paras. 7.189-7.194. - 123 -
well as massive development of cyanobacteria, especially in the shallow sections o512he river with a
low flowrate such as the bays of Yaguareté (Uruguay) and Ñandubaysal .
5.33. As regards the volume and characteristics of the anticipated discharges, it is striking to
note that the decision-making process followed by Uruguay at no point required the promoters of
the project to supply clear and detailed informat ion as to the volume of liquid effluent to be
discharged into the river. Such information ought, however, to have been included in the
statements on the environment made by the proj ect’s proponents. That was not the case. The
Wheater report specifically criticizes the Cumulative Impact Study (CIS, carried out by the IFC),
and consequently the Orion environmental impact assessment on which it is based, because it failed
to deal with the uncertainties relating to effl uent loadings, contaminant concentrations and
ecological response. The report notes, for example, that the issue of uncertainty could be critical as
regards estimates of metals emissions and that “instead of being neglected, [it] warrants explicit
attention in effluent load calculations and predictions of water quality” 51.
5.34. The Hatfield report criticizes the environmental impact assessments supplied to the IFC
on several grounds, particularly because: they do no t define the mill designs in sufficient detail to
determine whether the mills will i ndeed use the best available technologies; they do not provide a
complete listing of discharges into the environment in the vicinity of the mills; the data presented
overestimate the quantities of many pollutants that will actually be discharged (the report adds that
209 excessively conservative estimates distort the ev aluation process and lead to unnecessary concerns
on the part of the public, while underestim ating similarly distorts the analysis) 514. The Hatfield
report is particularly critical of the environmen tal impact assessment carried out for the Orion
project and notes that it does not provide details of the water quality downstream of the Orion mill
or of 515 aquatic resources (fauna and flora) present in the area on a temporary or perman516
basis . The absence of bioassay tests on local fish species was also criticized .
5.35. Since the report was drawn up, the promoters of the project and/or the Uruguayan
Government have supplied additional information, but nonetheless some crucial information is still
517
unknown, as is noted in Chapter VII . The Latinoconsult report identified five areas of
uncertainty which continue to exist because of:
1. inadequate delineation of the plume, meaning that it is not possible to characterize the potential
exposure concentrations that will be experienced by biological receptors;
2. the lack of information on the residency pe riods, seasonal reproductive cycles, and critical
periods of development of exposed biota, whic h means it is difficult to predict impacts of
exposure;
3. the lack of baseline data on contaminant levels in fish, meaning it will be impossible to separate
out the mill’s contribution to contaminant burdens from other sources;
51See Chap.VI, para.6.41, and Chap.VII, paras.7.44, 7.185-7.186 and 7.189-7.190. See also paras.31-34 of

phosphorus and effects on plankton) and Sec. 6.7 (role of phosphorus in nutrient enrichment).

51See in particular paras. 7.128-7.132 and the references to the Latinoconsult report which they contain. - 124 -
4. the absence of a clear description of the de tailed plans for post-operational monitoring,
meaning it is not possible to determine whether the mill will in fact perform as expected;
210 5. the pos518ility of unanticipated effects of pu lp mill effluents has not been tackled at any
stage .
Nor can there be any dispute that the Orion m ill was authorized on the basis of insufficient
information and that no sort of information supplied ex post facto can remedy the breach of the
obligation prescribed in the 1975 Statute to take a ll the measures necessary to protect the river and
the areas affected by it.
5.36. Almost two years after the Orion mill au thorization, Argentina is therefore still in a
situation where it is impossible to determine the to tal volume of polluting effluent to be discharged
into the river each year or even th e exact nature of the discharges. Over more than 40 years, the
volume of discharges will in any event be very hi gh, but it cannot be quantified on the basis of the
information available today whether the river is capable of receiving that effluent. Uruguay’s
inability to take these basic m easures is in itself a breach of the provisions of Article 41 (a) of the
1975 Statute. Uruguay cannot properly argue that it has complied with the obligation incumbent on
it under Article41 (a) to take appropriate measures to prevent any pollution of the river, since it
has not carried out the actions necessary to be we ll informed about the volume of pollution to be
discharged into the river.
5.37. The question of the capacity of the river to re ceive and disperse polluting effluent is
another subject on which Uruguay has completely fa iled to ensure that sufficient information was
obtained. This point is discussed in Chapter VII below, in the context of an assessment of the
ecosystem of the river as a whole 519. In particular, the following questions have not been dealt with
satisfactorily: the frequency of reverse flow; pl ume dispersion; possible changes in the weather
cycle; and the role of sediments and geomorpholog y. As a result, the frequency of reverse flow
211 has been greatly underestimated. Flow reversal has a major impact on the plume of pollutants,
because when it occurs, the contaminants which had been diluted are carr520 back to the point of
discharge and the concentration of toxins there is then increased . As regards plume dispersion,
the impact studies carried out are based on an inaccurate model of the behaviour of the plume,
521
which makes the levels of dilution on which it is based incorrect . The possibility of a change in
the weather cycle has quite simply not been ta ken into account, with the consequence that the
extension of the estuarine area and the weakening of the flow which would occur as a result are
522
neither identified nor taken into account . Finally, the role of sediments and geomorphology has
not been examined satisfactorily. The River Ur uguay is a dynamic sedimentary environment with
fairly high sediment deposition rates which have an effect on the future trend of flow and pollution
523
transport .
5.38. The information available on the Orion m ill project is therefore wholly insufficient to
determine the capacity of the river to receive and disperse liquid effluent pollutants. The lack of
information is particularly serious when viewed in the light of the genuine possibility of an

alteration in the flow of the River Uruguay as a resu lt of climate change, particularly in conditions
524
which have not been anticipated or assessed at all .
5.39. The Hatfield report has already noted th ese shortcomings clearly and convincingly. It
states that “the documents in the public dom ain do not provide sufficient information for
stakeholders outside Botnia and ENCE to form reasoned opinions on many issues” 52.
212 5.40. The final CIS report has not dispelle d these concerns, as is shown by the reports
commissioned by Argentina which are described in Chapter VII. As stated in Part I of Chapter VII,
the River Uruguay is characterized by its shallo wness, the presence of sandbars and very slow
flow, which means that pollution transport will in turn be slow. It is also subject to the
phenomenon of reverse flow, whereby under certain conditions the river changes direction and
transports pollutants upstream. These features mean that significant quantities of pollutants
discharged by the Orion mill will not be transporte d downstream and out towards the sea. On the
contrary, significant quantities of these pollutants will remain in the area where they were initially
discharged and will be deposited in the sand and mud of the riverbed. They will also be
transported in large quantities upstream, where th ey are likely to reach sensitive areas, including
protected wetlands such as the Ramsar site Es teros de Farrapos, and thereby to produce effects
526
which Uruguay has utterly failed to assess . Moreover, the Latinoconsult report notes that
Botnia’s ornithological study recorded very low biological diversity because of the extremely short
duration of the sampling period, as recognized in the CIS report. Only two of the ten species listed
in the Convention on International Trade in Endangered Species of Wild Fauna a527Flora
(hereinafter “the CITES Convention”) were taken into account in the CIS report .
5.41. Argentina’s independent reports conclude d that there was considerable uncertainty as
to the environmental impacts of polluting discharges from the Orion mill in the River Uruguay, and
that these uncertainties had not been dealt with in the environmental impact assessment process
(see for example Sec. 3 of the Wheater report (analysi s of the uncertainty in predictions of effluent
loadings, contaminant concentrations, and ecological response) and also Sec. 7 (hydrodynamic and
water quality modelling)). Moreover, both the Wheater report (Sec. 2) and the Latinoconsult report
213 (Sec.4.2) criticize the unjustified use of diluti on ratios that were developed for the Canadian
Environmental Effects Monitoring Programme in order to focus experimental resources and avoid
the need to sample in difficult and unsafe circumstances. The Wheater report is particularly critical
of the modelling approach used in the IFC’s CI S report, which it describes as “poorly presented”
and “inadequately detailed”, concluding that the c onfidence placed in the models is unjustified and
misleading 528. The marked lack of analysis of a wide range of scientific uncertainties is discussed
in Chapter VII. As noted in the reports referre d to by Argentina, there are serious, pervasive
shortcomings in the entire assessment process. Th e failure to take account of the key issues of
scientific uncertainty renders utterly irrelevant the conclusion of the CIS that no adverse effects are
to be anticipated for the environment or human health.

5.42. It is also clear that the concentra tion limits for phosphorus set out in the CARU
documentation will be reached in a short period of time (see the arguments put forward in Sec. 6 of
the Wheater report (nutrients) and Chap. VII) 529.
5.43. Discharges from the Orion mill will create very serious risks of eutrophication and the
530
proliferation of algae, particularly in Ñandubaysal Bay .
5.44. It is therefore clear that Uruguay has not taken all measures to prevent pollution of the
River Uruguay and the areas affected by it. These fa ilures to fulfil its obligations, taken together,
constitute a clear breach of the provisions of Article 41 (a) of the 1975 Statute, and other provisions
thereof. Among other things, a number of sp ecies protected under the CITES Convention are
recognized to be at risk.
214 B. Uruguay has failed tov take all measures to protect and preserve the biological diversity of
the River Uruguay and the areas affected by it
5.45. The obligation “to protect and preserve the aquatic environment” does not relate solely
to an obligation to protect the quality of the waters of the River Uruguay, but also to an obligation
to protect the biological diversity of and associated with the river. The biological diversity in
question includes habitats as well as species of flora and fauna.
531
5.46. It will be shown in Chapters VI and VII that the waters of the River Uruguay are
unquestionably home to a wide range of biological diversity: over 100species of fish (some of
which are regarded as in critical danger of extinction by the International Union for the
Conservation of Nature); amphibian and bent hic species, including tolerant and sensitive
organisms; a variety of bird species, including ten that are subject to threats of varying degree,
including Xanthopsar flavus (endangered, or 532nerable), Sporophila zelichi (critically endangered)
and Sporophila palustris (endangered) . Something which has not been mentioned in any of the
impact studies is that the Ramsar site Esteros de Farrapos is only a few kilometres upstream of the
Orion mill. It will be shown below that flow reversal means that the upstream limit of the
dispersion model is only 2.5 km south of the Ramsar site. It is estimated that for 1 per cent of the
time, dilution at the upstream limit of the di spersion model will be lower than 1:1000. The
minimum simulated dilution for this upstream limit was 1:200. It is anticipated that under certain
conditions, the plume may extend beyond the upstr eam limit in the dispersion model, reaching the
southern part of the Ramsar site 533. The CIS report states that reverse flow will not affect this
important site. The expert report commissione d by Argentina sets out why the CIS report is
incorrect: the frequency of reverse flow has been greatly underestimated and the consequences of
215 changes in climate have not been taken into account 534.
529See Chap. VI, para. 6.41, and Chap. VII, paras. 7.41, 7.43-7.44, 7.185-7.186 and 7.189-7.190.

5.47. Chapter III refers to a number of in ternational conventions on the protection of
535
biological diversity whic h apply in the present case . Article41 (a) of the Statute requires
Uruguay to have regard to and implement the obliga tions prescribed by such conventions. In this
context, the CITES Convention and the Conventio n on Biological Diversity require Uruguay to
comply with the obligations deriving from them in respect of activities undertaken on the River
Uruguay and the areas affected by it.
5.48. As with the protection of water quality , Argentina was entitled to expect that Uruguay
would carry out the studies required to ensure that the protection of biological diversity, especially
fishery resources, was secured. Uruguay should have taken the following measures to protect
biological diversity: (1) determine its state or situation in the River Uruguay and the areas affected
by it, (2) identify the volume and characteristics of the pollutants to be discharged into the river and
the surrounding area and (3) determine the impact of the pollutants on the biological diversity,
based inter alia on the requirements prescribed in the RAMSAR Convention on Wetlands of
International Importance especia lly as Waterfowl Habitat and the Convention on Biological
Diversity, and having regard to the existing sci entific uncertainties. Instead, as happened for
protection of water quality, Uruguay has not ta ken the appropriate and necessary measures to
protect biological diversity.
5.49. The question of the volume and characteristics of the anticipated discharges is studied
in ChapterVII as part of the discussion of wate r quality. The conclusions set out above are
216
applicable here, namely that Uruguay failed to ensu re the availability of the information needed in
order to determine the quantity or the characteristics of the pollutants to be discharged into the river
and the areas affected by it. As a result it is impossi ble to determine, on the basis of the available
information, what the likely impact on biological diversity might be, particularly as regards spe537s
of fish such as sabalo, boga and dorado, and other species used for human consumption . That
omission also constitutes a breach by Uruguay of the obligations incumbent on it under
Article 41 (a) of the 1975 Statute. Uruguay cannot properly contend that it has complied with the
obligation to protect biological diversity, since it has not even tried to find out what level of
pollution would be likely to affect it. These fa ilures to act also constitute breaches of other
provisions of the Statute, especially Articles 35, 36 and 37, which will be referred to later.
5.50. The information available from Uruguay is therefore utterly inadequate and does not
allow a determination to be made as to the capac ity of the river to receive and disperse polluting
effluents in such a way as to ensure the protection of biological diversity.
5.51. The reports commissioned by Argentin a, by contrast, identify the impact which
discharges of pollution will or, in certain instances, could have.
5.52. The independent reports presented by Argentina conclude that there is a very strong
likelihood that fish stocks will be affected, as w ill the diversity of the ecosystem, and that we are

537
See the Latinoconsult report, Executive Summary, para. 29, Anns., Vol. V, Ann. 3, which notes that the bays
are a feeding ground for the sabalo (among other species),ribed as a detritivorous, migratory fish, and states that
there is a potential risk of persistent pollutant biomagnification through the detritus food chain. - 128 -
witnessing increased frequency of toxic algae bloom as a result of eutrophication 538. Furthermore,
the Latinoconsult report concludes that there is an increased risk of pollution when the mill shuts
down and resumes operation (a risk which was not referred to in the CIS in a quantitative and
substantive manner), notes the unsatisfactory si ze of the emergency basin and criticizes the
217 539
unacceptable absence of a tertiary treatment facility . All these factors increase the risk of
harmful effects on biological diversity. The wi de-ranging environmental impacts that will produce
significant damage include: the accumulati on of sediments and associated contaminants,
particularly in Yaguareté Bay; an increase in eutrophication owing to higher levels of phosphorus
and other nutrients; the emission of unpleasant odours over an extended area; and an increase in
the risk of chemical spillages from river vessels. As regards odour, the IAEST team notes that it is
not just a matter of discomfort and poor quality of life. All total reduced sulphur (TRS) compounds
which give off an odour are toxic for the respiratory system. An epidemiological study of the
effects on health of TRS emissions from pulp m ills has shown that eye and nose symptoms and
coughing were more frequent in individuals exposed to 540els above 0.07 ppm (as a daily average)
than in individuals not exposed to TRS emissions .
5.53. In these circumstances, there can be no question that Uruguay has failed to take
measures to prevent pollution of the River Uruguay. Its failures to act constitute a breach of the
provisions of Article 41 (a) (as well as other provisions) of the 1975 Statute, on grounds including
its inability to fulfil the conditions laid down in Articles 3 and 5 of the Convention on Wetlands of
International Importance especially as Waterfowl Habitat, and Articles3, 5, 8 and 14 of the
1992 Convention on Biological Diversity.
C. Uruguay has failed to ensure that a full environmental impact assessment was produced
5.54. As was shown in Chapter III, it is well established in international law that the carrying
out of any activity which is inherently harmful to the environment is require d to be the subject of
218 an appropriate environmental impact assessmen t (EIA) from the time a project is conceived 541.
The objective of such EIAs is to prevent both harm to the environment and pollution. The lack of
an EIA (or the production of an inadequate EIA) prevents appropriate action being taken to prevent
environmental damage or pollution. Any EIA i nvolves drawing up an environmental assessment
which must include a minimum level of certain t ypes of information in order to comply with
international rules and standards 54. Where an assessment does not cover this minimum
information, as in the present case, the State in question cannot be regarded as having taken all
appropriate measures to prevent pollution.
5.55. There can be no dispute whatever that Article41 (a) requires Uruguay to obtain a
satisfactory environmental impact assessment, and that obtaining such an assessment is a necessary
and appropriate measure. Any State which has faile d to ensure that a satisfactory environmental
impact assessment has been carried out into an inherently harmful activity such as pulp production
has not complied with the obligation to take the appropriate measures to prevent pollution.
5.56. The obligation to carry out a satisfactor y environmental impact assessment arises from
the obligations laid down under Articles7 et seq. and Articles27 et seq. of the Statute. Uruguay

has infringed Article41 (a) and other provisions of the Statute by authorizing the construction of
the Orion mill on the basis of an inadequate e nvironmental impact assessment. The assessment
produced for the Orion mill was manifestly inadequate. It lacked, inter alia, an assessment of all
the possible impacts, a list of accurate initial data on the quality of the water in the river and its
ecosystem, and an explanation of the reasons which led to the choice of the site and the rejection of
other possible sites for the mill. International prac tice requires such data to be provided before an
environmental impact assessment can be regarded as containing sufficient elements for it to be
219 endorsed. In its report on the environmental impact assessment for the Orion mill, DINAMA
noted, however, that:
“[i]n the documents provided by BOTNIA during the assessment process for the EIA
information gaps, contradicti ons (even within the same document) and vague, rather
unsatisfactory replies were identified. Th e information received was also voluminous
but rather unclear, reiterative and, on occasion, superfluous and of low quality.” 543
Nevertheless, DINAMA authorized the Orion pr oject without appropriately assessing in advance
the impacts of the operation of the mill on the Rive r Uruguay. The failure to do so is made even
more serious by the fact that DINAMA had also authorized the construction of another pulp mill
(the CMB project) located only 7 km away 54.
5.57. In June 2005 ⎯ after Uruguay had approved the Orion project and authorized the
construction of the mill to begin ⎯ the IFC decided that the environmental impact assessment was
not satisfactory and that “further study was requi red of the cumulative social and environmental
impacts of the pulp mills projects, beyond those attributable to each plant’s operation” 545. The IFC
decision came in the wake of the complaint to its Compliance Adviser/Ombudsman by Argentine
and Uruguayan groups which regarded the impact assessment as incomplete 546.
5.58. The IFC appointed two independent experts and asked them to draw up a cumulative
547
impact study . The study process came to an end in December 2005 and a draft report was
submitted based on the assessments carried out by th e ENCE and Botnia undertakings. This draft
was subsequently subjected to further scrutiny by an independent group appointed by the IFC. The
220 548
result was the Hatfield report , several of whose recommendations noted the inadequacies of the
environmental assessments. Among their many shortcomings, the report drew attention to:
549
1. the scarcity of data regarding Uruguay River water quality and its biological diversity ;
2. incomplete identification and listing of discharg es in the natural environment in the vicinity of
550
the mill ;

3. absence of any independent review of the estimates of pollutant discharges presented by the

552
4. cavalier handling of the effects of discharges of dioxins and furans ;
5. the fact that the CIS did not provide a clear explanation of the site selection process employed
553
in respect of the Orion mill .
5.59. The final CIS report by Ecometrix did not address these difficulties. In particular,
Argentina maintains that, in the light of the re ports by experts who have examined the assessment
process, the following shortcomings (which are di rectly linked to those referred to above) still
remain:
⎯ the final CIS does not take satisfactory account of the impacts of the mills on the invertebrate
species which inhabit the river and its surroundi ngs. The potential impacts of the projects on
the invertebrates to the south of the planned mill are not assessed and the discussion of the risks
554
peculiar to amphibian species is insufficient ;
⎯ the final CIS concluded that: “[i]n general, the quality of [the] water . . . is considered good but
221
there are localized issues and exceedances of wate r quality criteria such as near Bella Unión,
Salto” etc. 555; but it makes no reference to any loca lized issues or any exceedance of water
556
quality levels on the Argentine bank ;
⎯ the issue of chlorophenolics in Yaguareté Bay is given cursory treatment 557;
⎯ the recommendation in the Hatfield report that detailed reasons and a decision-tree should be
supplied has not been acted upon 55.
It should also be noted that the expert reports to which Argentina refers in Chapter VII, especially
the Latinoconsult and Wheater reports, also provided updates on a number of other gaps and
weaknesses in the CIS which were not noted (or not fully noted) in the Hatfield report and were not
rectified in the final version of the CIS. Those points are set out in detail in Chapter VII, but as a
whole they point to an inability to take account of scientific uncertainty, particularly as regards the
following issues: use of computer modelling to me asure impacts on water quality; the effects of
dilution; and the impact of low concentrations of contaminants on the ecology. The reports also
note unsatisfactory assessment of the following aspects: plume dispersion, the impact of flow
reversal and the effect of a change in the weathe r cycle on the dispersion of pollutants. Similarly,
note was made of a failure to assess the risk of ch emical spills associated in particular with the
increase in river traffic.
5.60. Against this background, the position maintained by Uruguay whereby “potential
222 impacts on the river and on Argentina have been fully considered by DINAMA” 559is quite simply

untenable. Claims that the environmental assessm ents submitted by Botnia were “extensive and
detailed” 560are completely in the realms of fantasy. In short, in addition to the fact that they were
carried out unilaterally in breach of a bilatera l treaty (the 1975 Statute), the environmental
assessments are not complete and are inadequate in a number of respects. They are not, therefore,
satisfactory in the light of the standards of good practice and international law on the matter. 5 5
5.61. Nor did Uruguay ensure that appropriate consultation took place with the affected
communities, to allow those communities to participate in the process of assessing the
environmental impacts. The CARU minutes point to this absence of consultation with
project-affected communities 56.
5.62. The lack of information and consultation was highlighted by the Compliance
Adviser/Ombudsman (CAO) of the Interna565na l Finance Corporation and the Multilateral
Investment Guarantee Agency . Following a complaint lodged with the CAO on
23September2005 by a non-governmental organization, the Centro de derechos humanos y
566
ambiente , the preliminary CAO report of November 2005 stated that:
“The consultation and disclosure pro cesses related to approvals for these
projects give the impression of being rushed, and presented as a fait accompli to those
223 being consulted. Too little emphasis has been placed on the trans-boundary nature of
the possible impacts of these developmen ts and there has not been sufficient
acknowledgement of the legitimacy of concerns and fears of communities that are
local to the project.
Further technical information and scientific facts will not be sufficient to
address the lack of trust that currently ex ists amongst those who are concerned about
the projects. Specific efforts must be implemented in order to ensure that people who
believe that they will be impacted are ab le to have trust in the process as well as
outcome of any additional studies.” 567
5.63. Uruguay therefore failed to ensure th at full environmental assessments were produced
prior to its decisions to authorize the constr uction of the Orion and CMB mills. Uruguay’s
decisions are not only unilateral and in breach of international law, but are also based on
unsatisfactory environmental assessments. This re presents a further failure by Uruguay to comply
with its general obligation to take all measures to prevent pollution of the River Uruguay.

D. By failing to fulfil its obligations under Chapter II of the 1975 Statute, Uruguay has not
taken all measures to prevent pollution
5.64. Chapter III has already referred to th e situation whereby a decision falling under the
jurisdiction of one State might have damaging c onsequences for the natural resources shared with
another State, as well as for the territory of that other State. It has been noted that recent
224 developments in international law seek to ensure that the neighbouring State is involved in the
decision-making process 56. The aim of such an approach is inter alia to ensure that pollution is
prevented. ChapterII of the 1975 Statute (Arts.7 et seq. ) prescribes mechanisms for prior
consultation, exchange of information and co -operation which go beyond those provided for in
general international law. The breach of t hose obligations was examined in Chapter IV 569. Those
obligations are closely linked to the obligation prescribed in Article 41 (a) of the Statute to prevent
pollution. They contribute to performance of th e latter obligation. Uruguay has therefore also
failed to fulfil its obligation to take all appropriate measures to prevent pollution by failing to
comply with its obligations to consu lt CARU, forward information to CARU ⎯ or, where
appropriate, to Argentina through CARU ⎯ and to hold consultations prior to authorizing the
Orion and CMB mills; in so doing, it has viol ated the obligations incumbent on it under the
1975 Statute.
E.Uruguay has failed to take all measures to prevent pollution in authorizing the
construction of the Orion mill at an inappropriate site
5.65. In Chapters VI and VII of this Memorial, Argentina explains the significance of the site
chosen for the Orion mill. Chapter III sets out the way in which international law required the
choice of site and the rejection of alternatives to be justified. In additio n to the water quality and
biodiversity protection aspects which must be taken into account, it should be noted that the site
570
chosen is an important area for tourism and is significant in other economic respects .
Gualeguaychú, in Argentina, is an important to urist centre where visitors come to enjoy the
beaches and the annual carnival, a popular trad itional festival held each Saturday between
7 January and the first weekend in March 571. People come from all over Argentina and abroad to
225 see the carnival. It is a key tourist asset for the country and contributes to the growth of other
tourism-related activities in the region, including beach resorts, ecotourism and sports, cultural and
spa tourism (there are a number of thermal spas). Finally, it is located precisely in the most
populated area of this section of the river. The issu e of the location of the Orion mill site has in no
way been handled satisfactorily, if at all, in the environmental assessment for the mill. The
assessment does not state that other sites were c onsidered, nor does it give the reasons why they
were discarded; it does not describe current e nvironmental conditions satisfactorily and does not
go into the potential impacts on the environment. Th e choice of the site for the Orion mill is at the
heart of the dispute between Argentina and Uruguay.
5.66. Uruguay claims that the sites “are environmentally an excellent choice” 573. However,
it offers no scientific references and no evidence in support of that statement, and nor has it
explained why those sites had been chosen, or why other less environmentally and economically

See CR 2006/47, para. 3 (Boyle). - 133 -
sensitive sites were not selected. As stated in Chapter II, Uruguay has not even agreed to discuss
these issues with Argentina 574.
5.67. During the public hearings on the request for the indication of provisional measures,
Uruguay made several errors of fact with rega575to the sites. First, it claimed that there were “no
ecologically sensitive areas close by” . That statement is incorrect for the reasons set out in
Chapter VII 57. The Esteros de Farrapos site is only 7km away from Orion ⎯ it is protected as
Ramsar site No.1433 in the List of Wetlands of International Importance under the Ramsar
Convention of 1971 57, to which Argentina and Uruguay are parties and to which Article 41 of the
1975 Statute refers. Secondly, Uruguay has argued that the sites we re located at a point where the
226 river is fully navigable and “deep”, thereby suggest ing that pollutants would disperse easily. That
assertion is also false for the reasons set out in Ch apter VII. There is indeed a navigation channel
at the site but it has to be maintained by regular dredging, and outside the channel the river is less
than 1m deep in places 578. Thirdly, Uruguay has argued that the flow of the river would quickly
579
disperse the effluent discharges . That assertion is also false. The speed of the current sometimes
does not exceed 0.6 m per second, and this has a si gnificant effect on the capacity of the waters to
disperse the liquid effluents they will receive, as is shown in the independent reports commissioned
580
by Argentina . Flow reversal means that signifi cant quantities of pollution will be swept
upstream and may travel as far as the Ramsar site 581.
5.68. Uruguay has also failed to provide su fficient information on sedimentation. River
sediment is not examined in detail in the CIS a nd the issue of geomorphological change is not
tackled at all. The River Uruguay is a dynamic sedimentary environment featuring high rates of
local sediment deposition. On certain sections of the river, such as Ñandubaysal Bay, recent
measurements on the ground have s hown rates in the order of 0.015-0.02 m/year, a relatively high
rate which is indicative of an extremely dynamic sy stem. To illustrate the dynamic nature of this
process, satellite images show that there is a sma ll island some 10 km to the south of Ñandubaysal
Bay which was not visible on river charts 30 years before. Sedimentation has an impact on future
flow and the transport of pollutants 58.
5.69. By using a lower sedimentation rate, th e CIS fails to take account of geomorphological
227 changes which are closely linked to the deposition and accumulation of contaminants.
ProfessorHowardWheater describes this as a seri ous omission which is a matter of concern in
view of the significant changes observed over a few decades. This issue must be resolved before
any impact assessment can be regarded as complete.

5.70. Because of the increase in the level of eutrophication, particularly in Ñandubaysal Bay,
cyanobacteria and cyanotoxins will appear more fr equently. The risks posed by cyanobacteria and
cyanotoxins are set out in detail in S ection6.7.2 of the Latinoconsult report 58. The report
examines the toxicity of microcystin and its implications for humans and animals. The report notes
that in temperate climates such as in South Am erica, bloom may occur for six to ten months 584in
bodies of water where the genus Microcystis is dominant. Where the concentration of phosphorus
is high (referred to above), hepatotoxic strains produce more toxins. Ejection into the surrounding
water produces dissolved toxins (principally during senescence, death and lysis of a cell) and poses
a danger to health.
5.71. The issues related to the location of the site have not been dealt with, as is confirmed in
the Hatfield report, which categorically stat es that Uruguay did not provide any satisfactory
explanation for the choice of the site for the Orion mill.
5.72. The final CIS report does not rectify these anomalies. As stated in Chapter VII, the
chosen location is not appropriate for the following reasons:
1. There is already a relatively high level of phosphorus (P) in the River Uruguay . That situation
is of great concern and poses a potential risk of eutrophication and proliferation of aquatic
flora, especially in the shallow sections of the river with a low flow-rate such as the bays of
228 Yaguareté and Ñandubaysal 585. The situation could have harmful effects on public health.
2. The area chosen is a fragile aquatic ecosystem of a quality which can and must be protected 586.
The bays of Ñandubaysal and Bellaco along w ith Inés Lagoon constitute a very productive
coastal area containing a wide variety of refuges for aquatic organisms and should as a result be
declared a natural sanctuary 587. Experts have confirmed a strong likelihood that fish stocks and
the diversity of the ecosystem will be affected by the pulp mills.
3. Flow reversal increases the likelihood of contaminants extending to sensitive areas 588.
4. Over 90 per cent of fishery production from the shared section of the river, or 4,500 tonnes per
year, comes from the area of the Orion mill site 589. There are concerns as to the
bioaccumulation of contaminants in species such as the sabalo which are used for human
consumption 590.
5. Gualeguaychú in Argentina is an important centre for tourism which attracts visitors because
of its beaches and the annual carnival. The b each resort of Ñandubaysal in Gualeguaychú is
thriving and welcomes almost 450,000 people each year. The resort’s great assets are its
beaches’ clear water and other aesthetic consid erations. Eutrophication, which leads to
unpleasant odours, health risks and unattractive water colour, together with the visual impact of

the Orion mill installations on the opposite bank, will have very significant negative
consequences for tourism 591.
5.73. Uruguay has chosen to locate the Orion mill in an area close to the CMB mill, the plans
for which have since been abandoned. Because of the nature of the waters which will receive the
pollution, the propensity of the site to sed imentation and eutrophication, the phenomenon of
reverse flow and the proximity of the largest se ttlement on the River Uruguay, this location is not
ideal for the dispersion of the quantities of pollutio n which are to be discharged into the river.
Therefore, by failing to take the measures necessary to determine the appropriateness of the chosen
sites, Uruguay has committed a further breach of the obligation incumbent on it under
Article 41 (a) of the Statute to take appropriate measures to prevent pollution.
F. By not requiring the mill to employ the “b est available techniques” Uruguay has failed to
take all measures to prevent pollution
5.74. Uruguay acknowledges that Article41 of the 1975 Statute “has the effect of
incorporating standards set by the 2001 St ockholm Convention on Persistent Organic
Pollutants” 59. Uruguay accepts that it is required to employ “the best available techniques” and
“the best environmental practices” as laid down in Article 5 (d) of the POPs Convention of 2001.
5.75. The Wheater and Latinoconsult reports confirm that the Orion mill will not satisfy all
the BAT standards. The European Union BREF document on the pulp and paper industry states
that tertiary treatment of effluent is necessary in some cases 59. These cases are where the nutrient
concentrations in the effluent have to be lowered if the mill discharges to very sensitive receptors.
230 The technique is mainly applied to reduce nutrient, especially phosphorus 594. The location of the
Orion pulp mill means that disch595es will be made into sensitive waters, making tertiary treatment
necessary if BAT standards are to be complied with; this has not happened in respect of the
Orion project.
5.76. Another breach of BAT standards h as also been noted and is linked to the lack of an
empty emergency basin to cope with a large spill or sign 596 ificant changes in effluents. BAT
standards require almost all spillages to be collected and sufficiently large buffer tanks for
storage of concentrated or hot liquids from the process to be used 59. These related standards are a
response to environmental and safety requirements, according to the European Union BREF
document. Orion states that the design of the mill includes
“three 8-h retention time basins (equali zation/emergency) that operate in a
semi-continuous manner, i.e. they are filled continuously, and then the effluent quality
in the basin is checked prior to discharge in to the AST. In the event that a spill has
occurred in the mill, the basin contents would have a high COD and would be
discharged into the AST in a manner that does not overload the system.”

However, equalization of the effluents takes place in two of the basins, which each have an 8-h
3
capacity and operate alternately (2 x 25,000 m ). The third basin, which also corresponds to eight
hours of normal output, will remain empty (25,000m ). As the IAEST notes, the extra basin
cannot be seen as an emergency basin in case of spilla ges or operating problems, since it is in fact
598
an operational facility and will be too small in the event of an emergency .
231
5.77. Uruguay’s failure to require the “best available techniques” and “best environmental
practices” to be employed therefore constitutes another breach of its obligation to take all measures
to prevent pollution.
G.By not applying CARU standards, Uruguay has failed to take a ll measures to prevent
pollution
5.78. The Latinoconsult report notes that the le vel of phosphorus (P) in the River Uruguay is
already high. That situation is of great con cern and poses a potential risk of eutrophication and
proliferation, especially in the shallow sections of the river with a low flow-rate such as the bays of
Yaguareté and Ñandubaysal. The DINAMA norm for surface water quality is 0.025mg/L for
phosphorus 599. Various samples taken by CARU in 1999 and 2001 on the right bank of the
River Uruguay near Gualeguaychú (in the bay and th e channel) range from 0.04 mg/L to 0.2 mg/L
(on average 0.097 mg/L) of total phosphorus: these results are well above the DINAMA norm of
0.025mg/L. It follows that, even if the production process at the Orion mill complies with BAT
standards, the receiving water is not able to absorb more phosphorus without serious levels of
eutrophication occurring as a result. The consequenc es for human and animal health are set out in
Chapter VII 60.
Section III
Uruguay has violated its obligation to prevent changes in the ecological balance of the
River Uruguay and the areas affected by it, in particular by significantly
impairing the River Uruguay and the areas affected by it
5.79. Article35 of the 1975 Statute places Uruguay under the obligation “to adopt the
232 necessary measures to ensu re that the management of the soil and woodland and the use of
groundwater and the waters of the tributaries of the river do not cause changes which may
significantly impair the régime of the river or the quality of its waters”. That crucial provision
affirms the importance which the parties to the Stat ute attach to protecting the quality of the waters
of the River Uruguay and its régime, and the existe nce of a clear obligation to avoid “significantly
impair[ing]” [the quality of] its waters.
5.80. Uruguay’s decision to carry out major eucalyptus-planting operations to supply the raw
material for the Orion mill is an activity wh ich has impacts on soil management and Uruguayan
woodland. This decision also has major cons equences for the quality of the waters of the
River Uruguay: the existence of the eucalyptus pl antations, which are of significant size, is being
used today to justify the operation of the Orion mill, and the use made of them will directly
contribute to the pollution of the river waters. Article35 places Uruguay under an obligation to
598
At the Gunns mill, the emergency basin has a 25-hour capac ity and the one at the Valdivia de Arauco mill has
enough capacity for 48 hours of operation.
599
See Art. 5 of Decree 253/79 for Cla ss1 (drinking water supplies), Class2(a) (irrigation), Clas(b)
(recreational purposes) and Class 3 (preservation of water flora and fauna), for total phosphorus).
60See Chap. VII, paras. 7.43-7.44 and 7.195-7.196. - 137 -
adopt “the necessary measures”. That includes an obligation to assess all the direct and indirect
consequences for the river of the decision to plant eucalyptus. In taking that decision, Uruguay has
not taken account of the indirect impacts of the use of eucalyptus pulp as a raw material by the
future pulp mill. At the very least, this means that it cannot impose its decision by presenting it as
a fait accompli: the fact that Uruguay took th e decision as an economic development matter
several years ago, but after the adoption of the 1975 Statute, does not mean it can evade the
environmental obligations incumbent on it under that Statute concerning the protection of the River
Uruguay and the areas affected by it.
233
5.81. Article36 establishes that the parties “shall co-ordinate, through the Commission, the
necessary measures to avoid any change in the ec ological balance and to control pests and other
harmful factors in the river and the areas affected by it”. That provision is equally important, for
four reasons. First, it confirms the fact that the Statute has a comprehensive approach to protection
of the River Uruguay and its ecosystem. Secondly, it clearly states that the Parties are to
co-ordinate the measures they are to take, an d that they are to take them “through the
Commission”: they are not entitled to determine on a unilateral basis which measures are
necessary to avoid “any change” in the ecological bala nce of the river. Thirdly, it lays down an
obligation which is extremely broad in scope, na mely to avoid “any change in the ecological
balance”. Fourthly and finally, the protected area encompasses the river and the areas affected by
it.
5.82. Uruguay has violated that obligation. It acted unilaterally when it authorized the Orion
mill without forwarding information to CARU ⎯ or, where appropriate, to Argentina through
CARU ⎯ pursuant to ChapterII of the 1975Statute, and did not notify CARU in advance ⎯ or,
where appropriate, Argentina through CARU ⎯ of the measures which would be necessary to
avoid any change in the ecological balance. Mo reover, it will be shown in ChapterVII that the
measures taken by Uruguay will not be sufficient to avoid changes in the ecological balance of the
river. Over a period in excess of 40 years, the further sedimentation, toxic algae and eutrophication
which the project will result in, especially in Ñandu baysal Bay, will together produce a change in
that balance. The impact on biological diversity will also lead to a change in the ecological balance
unilaterally imposed by Uruguay on Argentina in breach of the 1975 Statute.
5.83. In conclusion, it would appear that Uruguay has violated its obligations to:
(a) adopt all measures to protect the quality of the waters of the River Uruguay and the areas
affected by it;
234 (b) take all measures to protect and preserve the biological diversity of the River Uruguay and the
areas affected by it;
(c) ensure that a full environmental impact assessment was produced;
(d) take all measures to prevent pollution by failing to fulfil its obligations under Chapter II of the
1975 Statute;
(e) take all measures to prevent pollution in author izing the construction of the Orion mill at an
inappropriate site;
(f) take all measures to prevent pollution by not requiring the mill to employ the “best available
techniques”; - 138 -
(g) prevent changes in the ecological balance of th e River Uruguay and the areas affected by it, in
particular by significantly impairing the River Uruguay and the areas affected by it. - 139 -
C HAPTER VI
THE ENVIRONMENT AFFECTED BY THE PLANNED PULP MILLS
AND THEIR ASSOCIATED FACILITIES
Section I
The River Uruguay and the areas affected by it
as an environmental ecosystem 601
237 6.1. On the Argentine side, the waters 2 of the River Uruguay bathe Mesopotamia, a
biogeographical region of almost 200,000km formed by the provinces of Corrientes, Entre Ríos
and Misiones. This is a dynamic region influen ced in particular by the hydrological changes
stemming from the upper basins of the major rivers Paraná and Uruguay and, to some extent, by
the action of the maritime front on the Río de la Plata system. The region has its own
geomorphological, hydrological and limnological featur es, and contains a wealth and wide variety
of species as well as a great diversity of ecological t ypes. The taxa are spread across the different
habitats, interacting with the region’s aquatic and terrestrial communities as they adapt to them.
6.2. The upper basin of the River Uruguay flows through several strata of tropical forest
which changes abruptly into semi -deciduous woodland dominated by the paraná pine, currently
under threat from deforestation and replacement by species introduced into the ecosystem. On the
lower reaches, there is a predominance of herb aceous vegetation. The aquatic and riparian
vegetation is abundant, even though the mainstream current is variable because of the changes in
water level, the steep banks and rocky substrata, with grassland dominating in the more sheltered
areas. Reed beds are also common, encouraging the presence of other floating plants.
6.3. The riparian woodland follows the course of the water, forming a narrow strip which is
238 nonetheless densely populated with species of medium height. Towards the lower reaches, there is
almost total dominance of the sarandí blanco in the region along the Argentine bank, on the islands
and around the bays, as for example at Ñandubaysal and in the neighbouring areas.
6.4. The type of riparian vegetation is a ma jor factor in terms of incorporating into the
system deposited coarse particulate of the kind us ed by the benthic invertebrates inhabiting the
banks of the River Uruguay, which determines the characteristic fauna in these environments.
6.5. Along a substantial section of the River Uruguay there is a wide range of molluscs in the
different habitats, both gastropods and bivalves. Clams and sponges have also been identified.
6.6. The River Uruguay has a variety of characteristic indigenous benthic species.
Thirty-three species of meso- and macro-invertebrate s have been identified, which may be seen as
a high number in comparison with other bodies of water in South America. In the coastal area,
601For the references concerning this section, see Chap. VII below and the Latinoconsu lt report (“Assessment of
the fluvial environment of the propoBotnia pulp mill on Río Uruguay”), iparticular Anns. E, F and G, at
http://www.ecopaedia.com.ar/publico/ea_report/ (username: ea_annex; pa ssword: ea_annex). See also Anns., Vol.V,
Ann. 3, Vol. VII, Ann. 7 and Vol. VIII, Ann. 6. - 140 -
there is a wider range of environments, resulting in particular in the presence of macrophytes.
These have a direct effect on increases in diversity.
6.7. Among the organisms which have medium tolerance of pollution are some belonging to
the group of molluscs. These inhabit the hard s ubstrata of the bank and assume great importance
because they represent the main food source for many bottom-feeding fish.
6.8. The presence and abundance of benthic organisms is mainly determined by the nature of
the physical habitat (variety of habitats availabl e), the quality of the water and the availability and
quality of food sources. There is consequently a difference between a riverbank benthos (more
239 habitats available, greater diversity, coarse organic particulate, etc.) and a deep benthos (moderate
diversity, deposited fine organic particulate, etc.).
6.9. As a result, it may be concluded from a variety of biotic indicators that the present
ecological quality of the River Uruguay can be categorized as good to very good. This is
demonstrated in particular by the presence of se nsitive organisms in the River Uruguay, such as
Trichoptera and Odonata.
6.10. The ecological and economic importance of the benthos is significant, since the
organisms in these communities, especi ally in the coastal area, are either a resource in themselves
or the main food source for other species of comme rcial importance (bottom-feeding fish, birds).
Likewise, they play a role in recycling orga nic and polluting substances, with the resulting
downstream effects on the trophic system of the neritic community.
6.11. Several sections of the River Uruguay include wetlands featuring on the List of
Wetlands of International Impor tance recognized by the Conventi on on Wetlands of International
Importance especially as Waterfowl Habitat, 1969 (the Ramsar Convention). Wetlands are
ecosystems with higher productivity than terrestrial areas and support a substantial biodiversity of
fauna, birds being the group with the highest con centration among vertebrates. However, the very
fact of being concentrated where there is water makes them especially vulnerable to any changes in
their environment.
6.12. On the River Uruguay, aquatic birds are strongly represented by the Ardeidae,
Ciconiidae and Anatidae families.
6.13. Attention should be drawn to the value of the area in question for the conservation of
240 species, which has led to the designation of AICA s (Areas of Importance for the Conservation of
Birds) and areas coded ER02 ER03, including the one close to Gualeguaychú. This area is
characterized by a broad diversity of grassland bird s, including populations of at least ten species
that are at risk of extinction, such as the saffron-cowled blackbird, Narosky’s seedeater, marsh
seedeater, chestnut seedeater, black-and-white mon jita (Tyrannidae), dark-throated seedeater
(Emberizidae), grey-and-chestnut seedeater, bearded tachuri, bay-capped wren-spinetail and greater
rhea (Rheidae). Other threatened species pres ent in the area are the yellow cardinal and the
sickle-winged nightjar. This latter species appears in fragmented populations and is therefore more
prone to local extinction.
6.14. Certain species of tern (Sternidae), skimmers (Rynchopidae) and plovers
(Charadriidae) nest on the large sandbanks close to the River Uruguay. These sites are also - 141 -
considered to be of major importance because of their environmental features, as a permanent or
interim habitat for numerous aquatic species, incl uding the migratory Nearctic birds, some of
whose numbers are in decline.
6.15. Within the aquatic bird fauna of the River Uruguay and the areas affected by it, a series
of functional groups can be identified, according to the patterns of use of the available resources
and based on the feeding and habitat of each species: (i) birds that look for food while walking on
the shores and in the shallows (herons, sandpipers , gulls, white-faced and buff-necked ibis, etc.),
whose main source of food is aquatic invertebrates, in particular molluscs, crustaceans and insects
which they find along the beaches, in or out of water and with or without vegetation; (ii) birds that
swim and dive for food, such as rails (Rallidae) , grebes (Podicipedidae) and cormorants, whose
main source of food is fish; (iii) birds that l ook for food on the wing or from perches (kingfishers
and terns, seagulls and raptors), most of which eat insects and generally catch their prey in flight;
241 and (iv)birds that seek food in the emergi ng vegetation (Passeriformes, Furnariidae and some
Tyrannidae).
6.16. Among the species that feed on animal organisms (aquatic macro-invertebrates, insects,
crustaceans, fish, amphibians and other small vertebrates), herons and giant wood-rail are
distinguished by their height. Some of these bi rds wade through the shallows, while others watch
for their prey from a perch on the water. The os prey takes its prey from the surface on the wing.
This is a migratory species from the northern hemisphere. Sometimes less obvious in terms of size,
but with significant numbers and biomass in the warmer months, the sandpipers, gulls, white-faced
ibis and other shore birds that wade in the ri ver shallows to feed on insects, crustaceans and
molluscs are consequently more prone to bioaccu mulation of toxic substa nces. Coots and ducks
are among the omnivores and herbivores that find their food in the water.
6.17. In terms of birds nesting in the sector concerned, there are a substantial number of
aquatic species that nest by forming colonies in the region, for example herons, cormorants,
white-faced ibis, spoonbills, grebes, etc.
6.18. The mammalian fauna in the aquatic e nvironments in the region of the River Uruguay
consists of some 26indigenous species, allowing for those whose population status is currently
unknown but which have not been signalled as extinct in the region.
6.19. The composition of this fauna, which is linked to the aquatic environment, includes
species of the Didelphimorphia, Chiroptera, Cingul ata, Rodentia, Odontoceti and Carnivora, some
of which have a commercial value for the fur industry or for human consumption. Among these
242 species are some that eat almost only insects, ca rnivores that prefer fish, general carnivores,
omnivores and herbivores.
6.20. In terms of ichthyofauna, it should be poi nted out that this sector of the River Uruguay
belongs to the Paranoplatense province, even though it is situated in the ecoregion of
Lower Uruguay. This province has the greatest diversity of ichthyofauna in Argentina, since most
families in the dominant Cypriniformes order of the Ostariophysi are found there (sabalo, bream,
boga, pacu, catfish, vieja, armado, surubi, mojarra, etc.) as well as groups of marine origin (rays,
clupeids, anchovy, pejerrey, corbina, mullet and sole).
6.21. The River Uruguay, together with th e Paraguay and Paraná, acts as a corridor for
ichthyofauna, facilitating the entry of tropical and subtropical elements of aquatic fauna. This river - 142 -
and the areas affected by it also comprise a speci fic area of endemicity which is expanding further
on its upper reaches, in Brazilian territory.
6.22. All the fish species, except those that are endemic, are widely distributed in the
Río de la Plata basin, and their biological cycle takes place wholly or partly in the various areas of
the region.
Section II
The specific features of the River Uruguay where the planned pulp mills
and associated facilities have been unilaterally authorized 602
6.23. Four phytogeographical provinces meet in the region of Gualeguaychú: the herbaceous
243 grassland of the Pampas, the Espinal region, the district of Ñandubay and the riparian woodland,
which together with its aquatic habitats forms a complex and dive rsified ecosystem, rich in a
variety of natural resources. The area of interest is dominated by the riparian woodland, with
species of trees and shrubs that form a dense and relatively low mass of growth.
6.24. The area affected in Gualeguaychú incl udes, within a relatively small surface area, a
range of different environments that account fo r a substantial proportion of the variety of
vegetation in Mesopotamia. Within a radius of 50 km of the city of Gualeguaychú, it is possible to
identify five different natural regions determined by their distinct geological and geomorphological
features: the Pampas of the Entre Ríos region, th e former coastal plain now joined with the valley
of the River Paraná, the valley of the River Gual eguaychú, the valley of the River Uruguay and the
plain of the eastern bank of the Uruguay. Each of these natural regions has vegetation which is
largely characteristic, formed by different plan t communities that typify the phytogeographical
provinces of the Paraná, the Chaco and Espinal regions and the Pampas.
6.25. The Pampas area of the Entre Ríos region extends across most of the province of
Entre Ríos, covering the north west of the area of interest and including its highest points. It has an
undulating landscape shaped by the action of tri butaries of the Rivers Uruguay, Gualeguay and
Gualeguaychú on Quaternary sediments fro m the Hernandarias Formation of the Middle
Pleistocene that are very rich in montmorillonitic clays. The natural vegetation of the region
consists of pasture, dominated by mesophyte grassl and in terms of coverage of the upland areas of
the undulating landscape.
6.26. These grasslands are distributed across the entire phytogeographical province of the
Pampas. Those of Entre Ríos are marked by the dominance of grass species of the type
Mammillaria elongata and by the common occurrence of grass ty pes with subtropical distribution.
244 Also commonly found on these grasslands are comp osites, legumes, native species, Umbelliferae,
various types of Verbenaceae, etc. and others that can be used as fodder. This type of vegetation
has often been replaced by perennial crops of gr ass and fodder species (pastures) and annual crops
such as wheat, soya or sunflowers. In the lowe r areas of the undulating landscape where there are
streams and valleys, this type of vegetation gives way to three other kinds, the halophyte steppes,
the hydrophyte grasslands and the savannahs or xerophyte woodland.
60For the references concerning this section, see Chap. VII below and the Latinoconsu lt report (“Assessment of
the fluvial environment of the proposed Botnia pulp milRío Uruguay”), in particular Annexes C, D and F, at
http://www.ecopaedia.com.ar/publico/ea_report/ (username: ea_annex; pa ssword: ea_annex). See also Anns., Vol.V,
Ann. 3, Vol. VII, Ann. 7 and Vol. VIII, Ann. 6. - 143 -
6.27. There is also the former coastal plain, a region covering the south-west portion of the
area of interest and consisting of a plain which lie s at much lower levels than the Pampas of the
Entre Ríos region, based on Holo cene sediments. This plain was fo rmed in relatively recent times
by a combination of geomorphological processes of the sea coast and wind and river action. The
result is a complex patchwork including permanen tly swamped depressions, often associated with
former tidal channels, and vast flatlands w ith a succession of flooded areas, rises and sandy
deposits similar to coastal dunes. This diversity is reflected in a wide range of plant communities:
hygrophyte shrubs, humid mesophyte grasslands, the espinillo and ñandubay savannahs, and the
psamophyte steppes.
6.28. The River Uruguay runs through a deep valley that is 10km wide in the area of
interest. The environmental conditions in the va lley are strongly influenced by the morphogenetic
action of the river, which has deposited most of th e substratum, and by the effect of this mass of
water on the patterns of temperature and humidity (night and morning mists, for example). As a
result of these environmental features and the ac tion of the river in transporting propagules from
the north, flora from the Paraná province is found in the Uruguay valley, though in the form of very
245 few species. This region therefore harbours the mo st southerly populations of many species. The
characteristic plant types in this area of the Ur uguay valley are mainly marsh plants and riparian
trees and shrubs.
6.29. The River Gualeguaychú, the main tributary of the River Uruguay, which crosses the
Pampas of Entre Ríos, has cut through the sedim ent pile of the Hernandarias Formation and
exposed the sand and alluvial clay from the Ituzaingó Formation of the Lower Pleistocene. In this
valley, the woodland communities that typify the Chaco and Espinal phytogeographical provinces
are best represented; they are also present in the valleys of streams in the Pampas of Entre Ríos
and in parts of the valley of the River Uruguay. As in the rest of the region, the primary wooded
vegetation in Espinal has been much damaged and destroyed. The main types of woodland present
are xerophyte woodland and savannah, and riparian trees.
6.30 The aquatic organisms in the region are of different types. Among the benthic
organisms are a number of sensitive species: Tr ichoptera and Odonata, as well as Ephemeroptera,
certain bivalves and ancillids.
6.31. The highest densities of species occur in environments characterized by vegetation that
consists of reed beds in particular, pointing to th e major role played by riparian vegetation. It
offers both the refuge and the food source needed for the community of benthic invertebrates
associated with the vegetation to develop.
6.32. The small bays are characterized by mean values of organic matter (OM) in the
sediment that vary between 2percent and 7.3 percent, due to the continuous accumulation
encouraged by the lentic features of the site a nd the abundant plant cover. High OM values have
also been recorded in the centre of Ñandubaysal Bay, probably due to the proximity to the mouth of
the River Gualeguaychú, which carries nutrients and OM to the River Uruguay. Lower OM
246 content was found in the stations on the main be d (OM<1percent), where the greater depth and
hydraulic energy do not allow it to be accumulated, except in areas of deposition on the banks.
6.33. As has been indicated, there are 33sens itive species in the area, compared with an
average of between six and16 for other similar bodies of water in South America. The highest - 144 -
values are those for groups associated with the riparian vegetation in the main course of the
River Uruguay and Ñandubaysal Bay.
6.34. A number of biotic indices, both national and international, allow the ecological quality
of the River Uruguay to be categorized as good to very good. Particular attention should be drawn
to the presence in macrophytes of a wide range of benthic organisms, some highly sensitive, which
have a positive effect on these indices. Organisms sensitive to the highest environmental quality in
terms of these biotic indices have been identifie d in the bulrushes of Ñandubaysal and the reeds of
the main course of the River Uruguay. Among the Odonata, it is worth highlighting Phyllocycla
argentina, for example, a species found around the waterm ark or in areas of low current velocity,
with mainly sand, clear water and a high dissolved oxygen content.
6.35. There is a wide diversity of birds, including some 170species associated with the
aquatic environments and more than 100 in other habitats.
6.36. It is not possible to describe in thisMemorial all the different elements of landscape
within the geographical area consisting of the south- eastern part of Entre Ríos and the river bank.
Those elements that are jeopardized in visual term s are in particular the views from the resort of
Ñandubaysal or from the “General San Martín” international bridge.
247
The resort of Ñandubaysal on the River Uruguay
6.37. The landscape within the geographical area of the south-eastern part of Entre Ríos is
rural in nature, with a wealth of biological diversity. Very close to the “Libertador
GeneralSanMartín” bridge, which links Fray Be ntos and Puerto Unzué, is the Inés Lagoon, a
shallow river inlet which is a breeding site for several migratory species of fish. Five kilometres to
the south is the mouth of the River Gualeguaychú, a tributary of the River Uruguay which is
subject to the latter’s high and low water periods.
6.38. The main focus of tourism in the area is Ñandubaysal Bay, whose environment has
natural features in the riverside areas and a landsca pe enclosed by planted woodland, together with
wooded parks and a wide beach on the river front. - 145 -
6.39. The landscape along the section of the River Uruguay under review is a very fragile
248 one in visual terms, given its lack of contours and the dense but low riparian vegetation. This
suggests that it is not an environment in which large objects or structures can easily be concealed.
The planned Orion pulp mill
6.40. In biogeochemical terms, the River Ur uguay has fairly homogeneous characteristics:
low turbidity (~30-35mg/L), a generally stable downstream current, a shallow depth (8to 10m)
and mainly sandy bottoms, reducing sharply towa rds the Argentine bank with an accompanying
increase in the proportion of fine sediments. Below are some specific features of the area in which
the planned pulp mills and associated facilities have been unilaterally authorized:
⎯ River Uruguay: depth of some 8m, deposition of coarse materials, sandy bottoms with low
249 organic matter, lower concentrations of suspe nded material and chlorophyllA with abundant
degraded pigments and high nutrients. Corresponds to a system of low to moderate
productivity (oligo-mesotrophic) with potential to increase its trophic status.
⎯ Bellaco and Ñandubaysal Bays : semi-closed shallow bays (1.5-2m) with weak circulation
based on circular models, higher amount of su spended solids, deposition of fine materials,
clayey-silty bottoms, high concentrations of ch lorophyllA with little degraded pigment and
low nutrients. Constitutes a meso-eutrophic enviro nment with strong vertical fluxes of fresh
phytoplanktonic matter which acts as a feeding a nd breeding area for various aquatic species.
Inside the bays, there is mainly clayey-silt y sediment and abundant biological productivity
(plankton).
⎯ Inés Lagoon: very shallow lagoon (0.3-0.5 m), rapidl y filling up with sediment and acting as a
trap for fine materials, with 20-50cm of water at the time of sampling, high turbidity
(~160 mg/L), fine to very fine sediment, streams and refuges with abundant aquatic vegetation.
High amount of suspended solids, clayey-silt y bottoms with frequent re-suspension,
intermediate values of chlorophyll A with degr aded pigments and low nutrients. Corresponds
to a transitional wetland, with abundant pal udal vegetation and a dive rsity of refuges.
Connected to the River Uruguay by the Arroyo Pereyra to the north and to Ñandubaysal Bay
by a coastal channel and a marshy area to the south.
6.41. The area presents an optimal environm ental condition with a very low background of
anthropogenic contaminants, mostly derived during the last 15-20years. Trace levels of PCBs, - 146 -
petrogenic aliphatic hydrocarbons, pyrogenic arom atic compounds and chlorinated pesticides have
250 been detected in both sediments and biota, well below the recommended guidelines. The heavy
metals occurring in the area are predominantly of natural origin.
6.42. The bays and the Inés Lagoon form a very productive ecological unit with a diversity
of refuges for various aquatic species which might be protected as a natural sanctuary.
6.43. Summarized below are the most signifi cant features of the area in which the planned
pulp mills and associated facilities have been unilaterally authorized:
⎯ The area has optimal environmental conditions with low anthropic impact. The organisms
found there present very low levels of all contaminants.
⎯ The River Uruguay presents a lower trophic status with lower chlorophyll A concentrations, a
higher proportion of degraded pigments and higher nutrients.
⎯ Bellaco and Ñandubaysal Bays are a high-produc tivity, meso-eutrophic environment exporting
fresh organic matter to bottom sediments and to the River Uruguay, where it is consumed by
benthic and detritivorous organisms. Th e bays present the highest chlorophylA l
concentrations, low degraded pigments, nutrients reduced by biological consumption, and large
vertical fluxes (sedimentation rate~1.55cm/y ear) including fresh algal material, with net
accumulation of organic-rich fine sediments.
⎯ Inés Lagoon is a filling-up transitional wetla nd with abundant aqua tic vegetation and a
diversity of refuges.

The River Uruguay as a focus for sustainable development and the health
603
and well-being of the neighbouring communities
6.44. The Geographical Gross Product (GGP) of Entre Ríos reached2percent of national
GDP in2003. Within the GGP, the tertiary sector has the highest importance with more
than 65 per cent of the total, including tourism in particular, followed by the secondary sector with
almost20percent; lastly there is the primary sector, representing15percent of the provincial
product.
2
6.45. The Department of Gualeguaychú covers nearly 10,000km . It has a population of
over 100,000, nearly 75 per cent of whom live in its capital, the city of Gualeguaychú. More than
half of this population is aged between14 and64, representing a large proportion of the
economically active sector. In 2001, 97.7 per cent of the population aged over 10 was literate.
6.46. In 2003, the Department of Gualeguaychú accounted for some 10percent of the
provincial product.
60For the references concerning this section, see Chap. VII below and the Latinoconsu lt report (“Assessment of
the fluvial environment of the proposed Botnia pulp mill on Río Uruguay”), in particular. , at
http://www.ecopaedia.com.ar/publico/ea_report/ (username: ea_annex; pa ssword: ea_annex). See also Anns., Vol.V,
Ann. 3, Vol. VII, Ann. 7 and Vol. VIII, Ann. 6. - 147 -
6.47. Historically, the main basis of the economy of the Department of Gualeguaychú has
been agriculture and stock-farming. The region has many livestock, dairy and poultry farms. The
main crops grown in the Department are rice, maize, soya and wheat.
6.48. The population of the Department of Gualeguaychú has better access to mains water
252 than the provincial average. There is a drinki ng water plant in the northern area of the city of
Gualeguaychú. Work on this plant has made it possible to improve considerably the quantity and
quality of its output, which has been combined w ith an increase in reserve capacity and the boring
of wells at different points in the city, serving to reinforce the system. This was in response to the
extension of the mains network, with more than 10,000 additional connections in the northern,
3
eastern and southern sectors. The plant has an output capacity of 950m per hour. The city
currently has almost 22,000sites where service is available, and 87percent of the urban area is
connected to the mains network.
6.49. A combined water and sewerage plan is currently under way, a project developed and
managed by the Public Works Department, which is also responsible for the service as a whole.
This is intended to expand and renew the mains network in order to serve the entire population.
6.50. The treatment plant for domestic wastewater (from homes, businesses and public
institutions) has a surface area of 22hectares. It consists of three parallel sets of aerated
stabilization and sedimentation basins with accompanying facilities (pumping station, sand trap,
outflow measuring chamber, chlorination chamber, landfill site for solids dredged from the basins),
its purpose being to remove contaminants through the process of natural stabilization.
6.51. The treatment plant was designed for a population of 112,000 inhabitants served by the
drainage system, that being the estimated population 20 years after its commissioning.
6.52. The urban area of Gualeguaychú has 8.5 km of drains for rainwater, which otherwise is
surface run-off.
6.53. The tree population is generally in good condition. In one part of the city of
253 Gualeguaychú alone, there are more than 10,000trees and space to plant almost 8,000others. In
the rest of the city, there are between 5,000 and 7,000 further trees.
6.54. Tourism is now the most dynamic sector in the region. Tourist activity is developing
mainly around the “Country Carnival”, which ta kes place annually and attracts visitors from
Argentina and abroad. Other attractions are the thermal spas and activities linked to the river and
its beaches, e.g., general recreation, watersports and fishing.
6.55. Natural resources play a major role in the economy of the province. Many species of
mammalian fauna associated with the aquatic envi ronments have a commercial value for the fur
industry or for human consumption.
6.56. Tourist activity in the Gualeguaychú region is very significant. It underpins other
related economic activities, such as travel agencies, accommodation, restaurants, transport, car hire,
shops, and cultural and leisure services. - 148 -
6.57. The main tourist products offered by the Department of Gualeguaychú are: the
carnival, the beaches, nature, sports, recreation, cultural activities and the thermal spas. Of these,
the best developed are the carnival of Gualeguaychú and riverside tourism, the latter being directly
linked to nature.
(i) Carnival of Gualeguaychú . This is a traditional local festival held every Saturday from
7 January until the first weekend of March. To stage it, the city has a special amphitheatre
254 holding 40,000 people. This venue is the second largest of its kind in Latin America, after
the one in Río de Janeiro. There is a co mpetitive parade of four processions, with
hand-crafted displays that take more than 2, 000people to produce. Carnival spectators
engage in other activities during the day, mainly those linked to sun and beach recreation.
This is without doubt the main tourist asset, which has boosted other market segments.
(ii) Sun and beach . This product is represented on th e one hand by the resorts along the
RiverGualeguaychú and on the other by the beaches of Ñandubaysal. These are among
the largest in the area, situated 15km from the city of Gualeguaychú on a bay in the
River Uruguay, and are popular with tourists because of their quality and size.
Leisure activities on the River Uruguay
(iii) Nature. Ecotourism is being developed through activities linked to rural areas and in the
parks close to the city, such as the Parque Unzu é. Included in this segment are visits to
255 the private municipal reservation of Las Piedras for bird watching and guided walks.
(iv) Sports tourism. This is based on watersports, the services offered by marinas, and boating
on the river. It also includes fishing, mainly for pejerrey in winter.
(v) Recreation and cultural tourism . The former includes the casino, theatres, discothèques
and cafés; the latter covers visits to museums and historical and religious buildings. This
activity supplements the two main products mentioned above, the casino being especially
worthy of note.
(vi) Spa tourism. Gualeguaychú is the nearest spa centr e to the capital, Buenos Aires. The
largest complex has saltwater pools with temperatures of 38 ˚ to 40 ˚C, two of which are
covered. This is a product that is currently being developed through new investment.
6.58. The main indicator of tourist activity in the area is the substantial number of tourists
visiting the city of Gualeguaychú, especially for the beaches and nearby nature attractions. There
are more than 400,000 in the high season and 90,000 in low season, leaving aside the fact that the
average number of days per stay has increased. - 149 -
6.59. A second indicator is the number of establishments providing accommodation for
tourists.
256 6.60. A third indicator which shows the scale of the activity is the workforce employed, even
if there is some seasonal fluctuation as regards the riverside activities.
6.61. A fourth indicator is investment in the sector: in addition to the investment in hotels,
the first themed casino in Latin America has been opened, the motor-racing track has been
extended, the amphitheatre that stages the car nival processions has been renovated, and a new
convention hall and second thermal spa complex have been built.
6.62. Activities geared to active tourism and health are also an important factor during
weekends throughout the year. Spa tourism is pa rticularly in demand for health, relaxation or
simply enjoyment.
6.63. More than 80 per cent of the tourists a rriving in Gualeguaychú are engaged in riverside
tourism; this is focused on the resort of Ñandubaysal, which has become the major market
attraction and remains a preferred destination becau se of the quality of its gently sloping beaches
and very white sand. Near the resort, archeologi cal sites have been discovered relating to various
aboriginal ethnic groups that once lived there.
6.64. “Aves Argentinas” (Birds of Argentina) and the World Council of Birdlife
International, with the support of the Ministry of Foreign Affairs, International Trade and Religious
Worship, have publicly and officially announced the first six “Areas of Importance for the
Conservation of Birds” in Argentina, including the area of Ñandubaysal.
6.65. In conclusion, the part of the River Uruguay and the areas affected by it where the
planned pulp mills and associated facilities have been unilaterally authorized is an especially
257 sensitive one from the environmental point of view. This is in particular because of its enormous
biological diversity and the purit y of its ecosystem. These characteristics have enabled the region
of Gualeguaychú and the resort of Ñandubaysal and its neighbouring areas to be significantly
developed for tourism, which has thus beco me a source of revenue for the more than
100,000people living in Gualeguayc hú and the other communities nearby. For these inhabitants,
the conservation of the River Uruguay and the areas affected by it is closely linked to their own
quality of life. - 150 -
C HAPTER VII
T HE ENVIRONMENTAL IMPACTS OF THE O RION PULP MILL
Section I
Introduction
7.1. This chapter deals with the environmen tal consequences of the planned Orion pulp mill,
261
in the light of the information derived from thenational and international environmental impact
studies and the reports by independent experts co mmissioned for the purposes of this case. The
mill has been planned by a Finnish company, OY Metsä Botnia AB (Botnia), and is to be built near
Fray Bentos in Uruguay. The documents referred to in this chapter sometimes use the term “Orion
mill” for this proposed pulp mill.
7.2. The factual and legal background to the authorization of the Orion mill by Uruguay has
been set out in Chapters II and III. Those chapters show that what lies behind the adverse effects of
the planned mill on the River Uruguay and the areas a ffected by it is the breaching by Uruguay, to
the detriment of Argentina, of an international treaty, the Statute of the RiverUruguay of 1975,
which regulates a shared resource by means of specific norms that comply with the universally
recognized rules and principles of international law on protecting the environment.
7.3. This chapter is divided into five part s. SectionII describes the present environmental
situation and quality of the River Uruguay and the nearby areas affected by it. Section III describes
the operation of mills such as the one planned a nd assesses the typical environmental impacts of
this kind of pulp mill, including a number of intrinsi c environmental risks. It deals in particular
with the effects of water abstraction and of discharges and emissions into the river and its
environment, including the atmosphere. Section IV describes in some detail the planned operating
modes for the Orion mill and the types of discharges it would produce. SectionV describes the
262
effects on the environment of the RiverUruguay and the areas affected by it resulting from the
construction and operation of the pulp mill, on the b asis of the reports that are available. These
include, in particular, the effects on air and water quality, noise pollution, visual and general
nuisance and risks to human and animal health, for example from the appearance and spread of
algae. The specific impact on the tourism sector is also mentioned. SectionVI concludes by
drawing together all the elements of this ch apter in order to show how, in breach of the
1975Statute, Uruguay granted authorization for a mill on the RiverUruguay that is “liable to
affect . . . the quality of its waters” without being able to demonstrate that it had taken all necessary
measures to protect and preserve the aquatic envi ronment of the River Uruguay and to prevent its
pollution.
7.4. In general terms, this chapter will showthat no detailed and exhaustive study has yet
really been produced of all the possible risks to the environment presented by this pulp mill. The
uncertainties inherent in the assessment of the risks posed by the Orion mill are key to any
assessment of this project, especially in view of the serious consequences for water quality, aquatic
life and human health, not least through the bioaccumulation of pollutants in the food chain or
other forms of exposure to toxic chemical substances. These uncertainties have not been dealt with
in any satisfactory way at all during the impact ass essment procedure. The conclusions are set out
in Section VI of this chapter. - 151 -
7.5. The principal documents referred to in this chapter are as follows:
(a) “Assessment of the Fluvial Environment of the Proposed Botnia Pulp Mill on Río Uruguay at
263 Fray Bentos, Uruguay”, a report prepared by Latinoconsult S.A. for the Argentine Secretary for
the Environment, dated 5Decemb er 2006 (“the Latinoconsult report”) 604. The report also
refers to the work of the Independent Argen tinian Environmental Scie ntific Team (IAEST),
which developed an assessment of the environm ental characteristics of the River Uruguay and
considered the effects of the proposed project 605.
(b) “Review of the IFC Cumulative Impacts Stud y for Botnia’s Uruguay Pulp Mill”, released
606
on 4December 2006 (“the Wheater report”) . This report was prepared by
ProfessorHoward Wheater and DrN . eil McIntyre of the Department of Civil and
Environmental Engineering, Imperial College of Science, Technology and Medicine, London.
Commissioned by Argentina, it focuses on those aspects of the environmental impact of the
planned Orion mill that are linked to air and water quality.
(c) “Cumulative Impact Study” (“the CIS”): the final version of the CIS on the Uruguay pulp
mills 607was revised by consultants from EcoMetrix Incorporated, SENES and Processys and
608
published in September 2006 .
The CIS was commissioned by the International Finance Corporation (IFC), a subsidiary of the
609 610
World Bank . Unless otherwise indicated, all references to the CIS are to this final version .
(d) Report of the Argentine delegation to the Argentina-Uruguay High-Level Group (“Argentine
264
report to the GTAN”): this report, dated 3Fe bruary 2006, sets out the conclusions of the
Argentine delegation to the GTAN, which were presented separately because of the failure of
this negotiating body 61.
(e) The environmental impact a ssessment produced by Botnia for the planned pulp mill. Botnia
612
presented its original environmental impact assessment (EIA) on 31 March 2004 .
(f) The Hatfield report: this examination of the draft CIS was commissioned by the IFC and
published on 27March 2006 (“the Hatfield report”). The analysis was prepared by two
experts, Mr.Neil McCubbin and Mr.L.Wayne Dwernycjuk of Hatfield Consultants. The

The CIS presents a joint assessment of the potential effects of the planned Orion mill and a second plant which
Empresa Nacional de Celulosa España (ENCE) was proposing to construc t upstream from the Botnia site. ENCE
announced that it intended to change the location of its proposed plant after work had started on the final CIS (FCIS).
608
A summary of the process of drafting and revising the CIS is contained in Secs.4.1.1-4.1.2 of the CIS,
pp. 4.2-4.7.
609
Following publication of the environmen tal assessment carried out by the ENCE and Botnia companies, the
IFC asked independent experts to conduct a cumulative impact study (CIS) in July 2005. This overall study was defined
as “a study of the cumulative social and environmental impa cts likely to occur with the development of these two pulp
mill projects in Uruguay. It focuses specifically on the cumulative impacts, although information on the direct impacts of
each specific operation is included where necessary.”Cumulative Impact Study ⎯ Uruguay Pulp Mills , 19 Dec. 2005,

study identifies major weaknesses in the draft CIS (and the environmental impact
assessments(EIAs) on which it is based), representing “a lack of information, rather than
environmentally deficient factors in the proposed mill designs and operations” 61.

in Uruguay , prepared by the University of the Republic and published in June 2006, and
265 Consultancy report on pulp mills , prepared by a team of experts co-ordinated by
Professor Marcelo Conti of the University of Rome “La Sapienza” 61.
7.6. Botnia prepared an EIA and submitted it to the Uruguayan Government’s Department
for the Environment (DINAMA) 615. The company first presented its original EIA (without
annexes) on616 March 2004 and then its final version on 7 April 2004 , when several annexes were
submitted . Botnia also supplied a number of further versions of its environmental report during
2004 which were not accepted by DINAMA. Ev entually, a version dated 2December 2004 was
accepted and declared final by DINAMA, which treated the Orion mill as a Category C project, i.e.
one that is potentially highly polluting.
7.7. Botnia contacted the IFC to obtain its support. In order to meet the conditions of its
Environmental Assessment Policy (OP 4.01), the IFC decided in June 2005 that a further study of
617
the cumulative social and environmental effects was necessary , and commissioned the CIS in
August2005. This was to consider the impact of the Orion mill and the pulp mill planned by
Empresa Nacional de Celulosa España (ENCE), and how each of these was to be supplied with raw
materials. The first draft CIS was published in December 2005 and was then the subject of a public
enquiry. It was also examined by independent experts. The report of these independent experts
was published in April 2006 as the Hatfield report, which identified major weaknesses in the draft
266 CIS. The CIS was consequently revised to take account of the recommendations in the Hatfield
report and the final version published on 12 October 2006.
7.8. Argentina commissioned a report on the effects of the Orion mill on the environment of
the RiverUruguay. This report was prepared by Latinoconsult S.A. 618and submitted to the
Argentine Government on 5 December 2006. It summarizes the key findings from a review of the
environmental impact statements produced in orde r to examine the effects of the planned Orion
pulp mill. The report by Professor Howard Wheater of Imperial College, London was published on
4 December 2006.

Division during 2004, and Botnia provide d complementary documentation which DINAMA described in its report of
11Feb.2005 as being “presented in a very vague fashion”and responding unsatisfactorily to the questions posed. See
p. 1 of the DINAMA report, Anns., Vol. V, Ann. 8.
61The CIS states that the cumulative impact assessmentinclude the potential effects associated with existing
projects and conditions, those of the propos ed projects, and those of other developm ents that are realis tically defined at
the time the assessment is prepared and would impact directly on the project area. See Sec. 4.0 of the CIS, p. 4.1, Anns.,

consortium of three consultancies, the others being IATASA (Argentina) and ESSA Technologies Ltd. (Canada). - 153 -
7.9. Lastly, Argentina would refer to Chapte r I of this Memorial for its comments on the
proposal for a second pulp mill by the Spanis h company Empresa Nacional de Celulosa
España (ENCE) and on the subsequent withdrawal of this project.
Section II
The present quality of the River Uruguay and the areas affected by it
7.10. The planned site for the Orion mill is on the left bank of the RiverUruguay, near the
town of Fray Bentos in the Uruguayan Department of Río Negro. The mill is less than 700 m from
the international frontier (formed by the line of the principal channel); the nearest Argentine
territory is the island of Santa Inés, some 1,600m away. The RiverUrugu619represents the
international frontier between Argentina and Uruguay in this region .
7.11. Most of the land near the project sites is used for agriculture and forestry. The river is
267 used for water consumption, fishing and recreation by the inhabitants of the region and tourists.
There are also beach areas of various sizes along both the Argentine and Uruguayan banks, which
are used for recreation and tourism. The beach resort of Ñandubaysal is situated to the
east-south-east on the Argentine bank, only 11km from the site where the Botnia project is
planned. The treated effluent from the Ori on mill will be discharged directly into the
River Uruguay.
7.12. The River Uruguay is, after the River Paraná, the most important river draining to the
Río de la Plata 620. Its watershed covers a surface area of approximately 365,000 km , of which
51percent is in Brazil, 33.5percent is in Argentina and 15.5percent is in Uruguay. Its lower
reaches, where the Orion mill will be located, ha ve been described in the CIS as estuarine
environments with a relatively wide (1.8km n ear Fray Bentos) and flat channel with numerous
islands. The river widens steadily, from 6km near Las Cañas to a maximum of 12km at Nueva
Palmira. The upper and middle reaches of the river, above the Salto Grande dam, have a relatively
narrow channel width, with a steep channel slope and various rapids.
7.13. The River Uruguay has a number of charact eristics that demand special attention when
it comes to authorizing a project which may significantly affect its quality. These include:
(i) the very shallow depth of major sections of the river;
(ii) the sandbars that are a feature of its bed;
(iii) its relatively slow current, which means th at transportation (i.e., dispersion and advection)
of pollutants will be slow; and
(iv)the phenomenon of reverse flow, which means that pollutants may be transported
268
upstream and remain near the area where they were initially discharged into the river.
These characteristics are particularly marked around the site chosen for the Orion mill. The fact
that they have not been taken into account by Uruguay, and that the siting of the Orion mill has not
been subject to assessment or appropriate prior examination, in accordance with the 1975 Statute, is
one of the central elements of the dispute.

620
See the CIS, p. ES.x, Anns., Vol. V, Ann. 6. - 154 -
7.14. The environmental and social setting of th e Orion mill project is described in Section 3
of the CIS. Argentina wishes to stress that th ere are many important aspects of the environmental
characteristics of the River Uruguay which have not b een dealt with fully in the CIS, or have been
621
dealt with erroneously . The deficiencies in the CIS are as follows:
(a) the occurrence of reverse flow is much more fre quent in the vicinity of the Orion mill than the
CIS acknowledges;
(b) the analysis of plume dispersion in the CIS is incorrect, because it is not based on typical or
622
critical scenarios . The concentrations of effluent in the plume are likely to be different from
those in the discharges from the mill;
(c) the recent hydrological data are representative of a wet weather cycle, and in future the project
may operate in dry weather cycle conditions in which the average flows are lower than those
used in the CIS.
The remainder of this Section draws attention to further shortcomings in the CIS analysis of the
environmental context of the Orion mill, as identified in the Latinoconsult and Wheater reports:
269 (d) failure to consider the potential role of river sediments and geomorphology;
(e) inadequate consideration of the environmental quality and vulnerability of the River Uruguay;
(f) failure to consider the full range of aquatic life forms in the River Uruguay;
(g) failure to consider the full range of other forms of biological diversity in the area;
(h) failure to address the effects of tree plantations on the water cycle;
(i) poor assessment of the socio-economic impact of the project.
7.15. (a)Reverse flow and other aspects : the RiverUruguay is subject to a phenomenon
variously described as reverse flow or, more generally, tidal conditions. This occurs when the river
current changes direction and flows upstream for gr eater or lesser periods of time. Attention was
drawn to the phenomenon of reverse flow in th e RiverUruguay and its implications for the
623
environmental impact of the pulp mills by the Argentine delegation to the GTAN . However, and
despite the fact that the issue was raised at a very early stage, Ur uguay has consistently refused to
take it into account.
7.16. The CIS recognizes the existence of this phenomenon 62. However, it claims that it
only occurs “a few times per year or less frequently” 625. This is a considerable error.
621
See Sec. 2 of the Latinoconsult report, pp. 13-18, Anns., Vol. V, Ann. 3.
622
According to an expert from the IAEST, in general term s, the analysis of plume dispersion in the CIS does not
underestimate, but on the contrary overestimates the concentrations of plume effluents in the receptors. It probably only
overestimates this concentration along or close to the pl ume axis, in so far as the CIS m odel uses dispersion coefficients
higher than those used by the Latinoconsult report.
623
See the Argentine report to the GTAN, Sec. III, p. 7, note 13. Anns., Vol. IV, Ann. 1.
624See the CIS, Sec. 3.2.1. Anns., Vol. V, Ann. 6,
625Ibid., p. 3.4. - 155 -
7.17. The frequency of this phenomenon of revers e flow has been gr626ly underestimated by
270 the CIS, as confirmed by the findings of the Latinoconsult report . This bears out the fact that
reverse flow occurs in total for around 23 per cent of the time (an average of 84 days per year). For
22 per cent of the time, these reversals are the r esult of tides (of up to 20 cm) and wind conditions
(winds aligned with the river). This type of re versal occurs on an average of 80days per year,
during which the flow reverses once or several time s during the day. For the remaining 1 per cent
(3or 4days per year), these reversals are the result of storm surges (and are referred to as “pure
flow reversals”). This type of reversal causes the river to flow backwards for at least 24 hours.
7.18. The frequency of these reverse flows has major implications for the dispersion of the
effluent plume, which was not acknowledged by the CI S. This is because when the flow reverses,
the contaminants which had been diluted are ca rried back to the point of discharge and the
concentration of toxins there is then increased. As the Wheater report notes: “The frequency of
flow reversals seems to have b een understated in the CIS. Th is point is well covered by
Latinoconsult (2006). If their analysis is accurate th en this is an obvious and potentially important
627
deficiency in the CIS.”
7.19. During such periods, the dilution in some “far fields” will be lower than the 1:1000
average value reported in the CIS 628. Effluent dilution values of the order of 1:693 in Ñandubaysal
Bay and 1:516 in Yaguareté Bay (in Uruguay) will be more frequent than is acknowledged by the
629
CIS .
7.20. Such levels of dilution several kilo metres away were considered worrying by the
IAEST. The Wheater report confirms that the CI S used a period which does not appear to be
representative. The report states that it is questi onable whether the 10-year flow estimate used by
271 the CIS is sufficient. It points out that the se nsitive nature of many of the receptors and the
potential hazards to the aquatic environment and hum an health mean that risks from less frequent
events may be unacceptable 630. The report concludes, on the one hand, that the lack of
consideration of more extreme low flow events is a deficiency of the CIS, given the potentially
unacceptable risks, and on the other hand that the st atistical uncertainty in the 5-year (or 10-year)
low flow from a 20-year record is high and should be reported so that some judgment can be made
about accuracy.
7.21. The Wheater report also identifies anothe r major area of uncertainty, namely the effect
of climate change on flow variability. It describes as an important deficiency the fact that climate
change is not considered at all in the low flow analysis (or in other aspects of the CIS) 631.
7.22. The other sources of uncertainty identifie d by the Wheater report are in particular the
following: (1) the flow régime and hence the 5-year low flow is mostly controlled by Salto Grande
dam operation. The CIS implicitly assumes that the flow distribution is not sensitive to any future
changes in the dam operation, noting that it is gene rally operated to maintain a natural flow régime

63See the Wheater report, Sec. 4, p. 4. Anns., Vol. V, Ann. 5. - 156 -
and that the reservoirs’ storage capacity is limited. (2) The CIS has estimated tributary inflows
below Salto Grande based on catchment area. This may be of poor accuracy due to spatial
differences in rainfall, hydrology and abstractions 632.
272 7.23. (b) Plume dispersion: the CIS has not taken account of the relatively frequent reverse
flow conditions, and for this reason the levels of dilution on which it is based are incorrect.
7.24. The Latinoconsult report analysed plum e behaviour under diffe rent flow conditions,
using a 2Ddispersion model (the MIKE21 m odel of the Danish Hydraulic Laboratory) 63. The
results of a unidimensional model (MIKE11) u sed to gauge and predict the currents of the
RiverUruguay provided input to the plume disper sion analysis. The simulation of effluent
transport was carried out for the same scenarios presented in the CIS.
7.25. When the MIKE21 and MIKE11 models are used and the real frequency of reverse
flow is taken into account, effluent flows towards the Argentine side of the river clearly appear
much more likely than under the average flows asses sed in the CIS. The Latinoconsult report also
confirms that concentrations reach higher values in Uruguay’s waters, near the Uruguayan bank 634.
The model likewise shows that large-scale eddies can occur, especially in open areas such as
Ñandubaysal Bay.
7.26. (c) Possible change in the weather cycle : Argentina recognizes that it is difficult to
predict the future trend of the alternation between dry and wet cycles in the River Uruguay, as this
will be influenced by many factors, including globa l warming. However, it can be anticipated, as
confirmed in Section 2.3 of the Latinoconsult report, that the river is approaching a dry period, or is
even at the beginning of it. The CIS does not allow for the possibility of this change in the weather
273 cycle, which would have the effect of increasing reverse flow and other ti dal phenomena, and the
weakening of the current that would result from such a shift is not taken into account in any way or
even contemplated in the CIS. For its part, Arge ntina maintains that any analysis of likely impact
should study the sensitivity to changes in the flow régime.
7.27. The shift to a dry cycle would affect low flows, which might be 440m 3/s rather than
the estimated 500 m /s used in the CIS. Reverse flow, which at present occurs about 23 per cent of
the time, would be expected to be in the order of 30percent (assuming the tides of the Río de la
Plata remain the same) 635.
7.28. To understand how future conditions in the River Uruguay may be further affected by
global warming would require exp licit consideration of predictions from regional climate models.
This has not been taken into account by the CIS or by Uruguay. That is a significant shortcoming:
it is possible that low flows will decrease in volum e and become more regular, which, if it were to
occur, would make the effects of reverse flow and tidal conditions even more serious, especially as
regards the dispersion and dilution of pollutants.

7.29. Furthermore, the future trend of weather cy cles could also be affected by the use of the
river and its watershed, including the building of dams. Land use will also be important, because
the gradual felling of forests will increase erosion. These elements have not been satisfactorily or
appropriately taken into account by the CIS.
274 7.30. These factors have a bearing on the relia bility of the predictions of plume dynamics
and dilution levels in the “far field” beyond th e immediate mixing zone. Predictions based on an
analysis of average equilibrium river conditions in the recent past may not appropriately
characterize the future conditions. As the Lati noconsult report team notes: “Consequently, it is
likely that within the lifetime of this project, the exposure of receptor sites to effluent from the mill
may be greater than predicted in the FCIS analysis.” 636
7.31. (d) Sediments and geomorphology : the CIS does not consider the river sediments in
detail and the question of geomorphol ogical changes is not addressed at all. The River Uruguay is
a dynamic sedimentary environment characterized by high rates of local sediment deposition. In
some sections of the river, such as the Ñanduba ysal Bay area, recent on-site measurements have
shown sedimentation rates of the or der of 0.015-0.02 m/year, a relatively high rate pointing to an
extremely dynamic system. To illustrate the dyna mism of this process, satellite images show the
existence of a small island around 10 km south of Ñandubaysal Bay which was not visible on river
charts 30 years before. This has implications for future flows and transport of pollutants 637.
7.32. By assuming a much lower sedimentation rate, the CIS takes no account of the
geomorphological changes that are closely linked to the deposition and accumulation of
contaminants. ProfessorHowardWheater sees this as a serious omission, and as a matter of
concern in the light of the significant changes ob served over a few decades. This issue must be
dealt with before any impact study can be regarded as completed.
275 7.33. The concentrations in water, which are taken into account by the CIS, do not reflect the
potential role in this respect of the accumulation of contaminants in sediment, nor the effects of this
on the food chain. The CIS does not address the question of the contaminants associated with
sediment or what becomes of them. As the Wheater report points out:
“Although accumulation of contaminants in the bays near the Botnia discharge
will probably be less than in a lake, due to smaller hydraulic and sediment residence
times, the significant discharge of AOX and other organics means there is significant
potential for accumulation. The CIS provides no evidence that this potential has been
reasonably explored through literatu re review and/or integrated
638
hydrodynamic-sediment-contaminant modelling.”
7.34. The Wheater report goes on to state that the CIS gives “an unsatisfactory justification”
for neglecting accumulation of sediment and associated contaminants in Yaguareté Bay. The port
development may increase the sedimentation rate by approximately 50 per cent, but the CIS merely
states that “other factors are expected to prevent accumulation of sediment within the embayment”
and that “net sedimentation in the bay is not e xpected to change”. The Wheater report rightly
63Ibid.
637
See the Wheater report, Sec. 5. Anns., Vol. V, Ann. 5.
638
See the Wheater report, Sec. 5, p. 5. Anns., Vol. V, Ann. 5. - 158 -
points out that this statement is counter-intuitiv e and 639t no convincing reasons are given as to
why the estimate of 50 per cent should be ignored .
7.35. Lastly, the Wheater report critici zes the CIS for its “cursory treatment” of
chlorophenolics in Yaguareté Bay. It points out that the estimated increase in the Yaguareté Bay
concentration under low flows (0.0003 mg/L) is not marginal when compared to background values
of 0.0001-0.0014mg/L, especially considering the sc ope for uncertainty in this estimated value,
276 and the coincident increase of suspended solids 64.
7.36. Argentina maintains that it is essential for the questions concerning sediment quality to
be studied in more detail before the impact study can be regarded as completed. As the
Latinoconsult report points out, there is a risk of persistent contaminant build-up in the form of
fine, organic-rich particulates accumulating in i nner sites. Moreover, the possible formation of
eutrophic zones in the RiverUruguay with an incre ased load of dissolved and particulate organic
material derived from the plume would increase the sedimentation of organic-rich particulates to
the bottom. Such organic hotspots may act as a ttractors for detritus-feeding fish, favouring the
641
bioaccumulation of persistent pollutants . Summing up, the Wheater report states that the
attention given to sediments and accumulation of sediment contamination “is very disappointing
and may be regarded as one of the CIS’s weakest elements” 64.
7.37. (e) Water quality: the dilution levels adopted by the CIS only take account of normal
flow régime conditions, without a llowing for reverse flows. As a result, the CIS has seriously
underestimated the dilution of effluents from the Orion mill in Ñandubaysal Bay, Santa Inés lagoon
and near the island of Santa Inés (on the Argentin e side). The IAEST’s calculations show that the
probability of dilution falling below 1:1000 is arou nd 10percent. Moreover, since this level of
dilution occurs on about 80days per year, it is clear that the water quality, in terms of levels of
exposure and effluent concentrations, has not been presented realistically by the CIS.
7.38. As pointed out by the Argentine report to the GTAN, the waters of the River Uruguay
277
that will receive the effluents are generally clean, with low levels of COD and BOD 5. Their pH
values are in the middle of the range recomme nded by the CARU Digest (5.6-8.9) and the
dissolved oxygen rate is 8.3 mg/L with 76.8 per cent saturation. However, it also appears that the
643
level of nutrients, in particular phosphorus , is such that any changes may produce an effect of
eutrophication, especially in summer 64. This means that the area in question is a fragile aquatic
ecosystem maintaining a degree of quality which can and must be protected 64.
7.39. The Latinoconsult report notes that Ñanduba ysal and Bellaco Bays, together with the
Inés lagoon, form a very productive coastal area w ith a large diversity of refuges for aquatic
63Ibid.

642
See the Wheater report, Sec. 5, p. 6. Anns., Vol. V, Ann. 5.
64The phosphorus concentrations in the area (average value: 0.093 mg/L) far exceed the maximum laid down by
the Uruguayan Decree 253/79 as amended ⎯ see p. 12 of the Argentine report to the GTAN, Anns., Vol. IV, Ann. 1.

organisms which would benefit from be ing declared a natural sanctuary 646. A summary of the
initial baseline analysis is contained in Section 6.1 of the Latinoconsult report.
7.40. The Wheater report criticizes the CIS for providing insufficient information to support
its statement that, despite the existing high nutrient levels, the increase in these levels due to mill
discharges will be insignificant. The report cons iders the consequences of the pulp mill treating
Fray Bentos municipal sewage, and states that while this solution would represent an overall
improvement in water quality, that may not be th e case at Yaguareté Bay and the site for drinking
water abstraction (both of which would beco me downstream of the municipal wastewater
discharge, whereas they were previously upstream). An improvement at these sites would depend
on the performance of the activated sludge reac tor (ASR) treatment system, particularly in
278 removing nutrients. But ASRs are not designed to remove nutrients, as reflected in the description
of the best available techniques for pulp mills in Europe (IPPC-BAT). Typical nutrient removal by
an ASR is 30-35percent, compared to about 90percent for BOD 5. Additional removal would
require tertiary treatment. Furthermore, the wastewater treatment requires extra nutrients to be
added in the form of urea and phosphoric acid; whether or not these extra nutrients are passed to
the receiving water, or are exported as sludge, depe nds on the performance of the ASR. However,
the added nutrients would not be needed if the municipal sewage is imported. Pointing out that
“Botnia has not yet specified a nutrient control strategy for its Orion WWTP”, the Wheater report
therefore states that the conclusion of the CIS “no adverse effect on human health or aquatic life” is
premature 647.
7.41. The Latinoconsult report indicates that the level of phosphorus(P) in the
River Uruguay is already high, which is a serious concern and represents a source of eutrophication
and the increased spreading of aquatic flora, particul arly in the shallow sections of the river where
the flow is low, such as Yaguareté Bay (Ur uguay) and Ñandubaysal Bay. The DINAMA norm for
surface water quality is 0.025 mg/L for phosphorus 64. However, various samples taken by CARU
in 1999 and 2001 on the right bank of the River Uruguay, near Gualeguaychú (in the bay and the
channel), range from 0.04mg/L to 0.2mg/L (on average 0.097mg/L) of total phosphorus; these
readings are well above the DINAMA norm of 0.025 mg /L. It follows that, even if the Orion Mill
operates in accordance with the best available techniques (BAT), the receiving water is not capable
of absorbing more phosphorus without this giving rise to serious levels of eutrophication. The
279 consequences of this for human health are considered in Section V.
7.42. The Hatfield report had also criticized th e draft CIS for the scarcity of data regarding
water quality and biological resources, particul arly related to the bay area downstream of the
649
proposed Orion effluent discharge . However, these concerns were only partially dealt with in
the final CIS ⎯ see below. Argentina therefore notes that the final CIS concluded that, “[i]n
general, the quality of water in the Río Uruguay is considered good but ther e are localized issues
650
and exceedances of water quality criteria such as near Bella Unión, Salto, etc....” , but points
out that this same CIS makes no reference to lo cal issues or the exceeding of water quality criteria
on the Argentine side of the river.
64See the Latinoconsult report, p. 28. Anns., Vol. V, Ann. 3.

purposes) and Class 3 (preservation of water flora and fauna), for total phosphorus.

65See the CIS, p. ES.xi. Anns., Vol. V, Ann. 6. - 160 -
7.43. The CIS also mentions the existence of run-off from agricultural areas and discharge
from urban centres and industries with inadequate e ffluent treatment. Sediment quality is likewise
considered good, but “some nutrients and me tals have been found to be elevated” 651. The
concentrations of phosphorus and nitrogen are described as “somewhat higher in the fall”. The CIS
points out that monitoring data for the vast majority of constituents shows compliance with
applicable water quality standards, with the possible exception of faecal coliforms, dissolved
oxygen, ammonia, phosphorus, chromium, iron and zinc. It states that these exceedances may pose
a risk to human health and aquatic life and affect the aesthetic quality of recreational waters. The
levels of phenolics were found to frequently excee d the water quality criteria, with the highest
values on the Argentine side of the river. It t hus emerges clearly from the CIS that a number of
280
pollutants, including phosphorus, are already present at high levels in the River Uruguay.
7.44. Nonetheless, the CIS seems to draw no conclusions from this finding, and fails to
underline the risk of eutrophication represented by any intentional increase in this already high
level of phosphorus in the river.
7.45. The CIS also notes that some chemical parameters relevant to pulp mill operations do
not have water quality criteria, and recognizes th at these parameters have not been routinely
measured in the River Uruguay. They include ad sorbable organic halides (AOX), chlorophenolics,
resin and fatty acids, dioxins and furans, and phytosterols. The CIS refers to the special studies
commissioned by Botnia which documented baseline le vels of these constituents in the river: this
indicates that the impact study has not been based on appropriate, independent measurements of the
baseline levels as regards the capacity of the rive r to absorb the emissions and effluents from the
mill.
7.46. (f) Aquatic life ⎯ fish : the RiverUruguay contains a wide variety of aquatic life
forms, in particular fish and amphibians, as well as other forms of biological diversity. The fish
populations include both dominant species and others that are dependent on them. The Argentine
report to the GTAN notes that the final stretch of the RiverUruguay, downstream from
FrayBentos, is an area of high diversity of fish species ⎯ more than 125species are cited ⎯
including some which are critically threat ened, according to th e World Conservation
Union (IUCN) 652. The report also describes this as the zone of greatest productivity and biomass,
281 653
with density values among the highest recorded in river environments anywhere in the world .
This diversity is mentioned by the CIS, which st ates that the lower RiverUruguay supports more
than 100fish species, of which 17are caught regularly, in particular sabalo, boga, mullet, dorado
and catfish654.
7.47. The CIS nevertheless states that no major migratory fish species or species important to
655
the fishery are known to spawn in the vicinity of the proposed mills . However, the effluents
from the pulp mills will be discharged into the rive r and contaminate the migration routes of fish
arriving to repopulate the river, which will have an effect on both subsistence and recreational
fishing.
65See the CIS, p. ES.xi and generally in Sec. 3.2. Anns., Vol. V, Ann. 6.
65The report to the GTAN notes that this point is recogni zed by the environmental im pact study presented by
Botnia, p. 12. Anns., Vol. IV, Ann. 1.
65See the Argentine report to the GTAN, p. 12. Anns., Vol. IV, Ann.
654
See the CIS, p. ES.xi. Anns., Vol. V, Ann. 6.
65See the CIS, p. 3.7. Anns., Vol. V, Ann. 6. - 161 -
7.48. According to the Argentine report to the GTAN, more than 90percent of fish
production from the shared stretch of the river, i.e. over 4,500 tonnes per year, comes from the area
in the vicinity of the Orion mill. This zone is al so a breeding area for stocks of migratory fish in
the RiverUruguay, with routes for drifting larvae which pass the effluent discharge poin
ts of the
two planned pulp mills. The aquatic life forms in this area may suffer the impact of discharges
with high concentrations of contaminating substances, such as AOX, COD and BOD . The GTAN
5
report also pointed out that the accumulation of dioxins and furans in the biota and the aquatic
environment needed to be measured 65.
7.49. The Wheater report, for its part, notes th at recent scientific literature on impacts on
aquatic life indicates that uncertainty about effect s is high, and points out that the CIS fails to
657
recognize this uncertainty in its conclusions . The report draws attention to the following
282 uncertainties: (1)bioactive substances continue to be released and detrimental effects on aquatic
life are still observed at some sites and may be present at others but undetectable with current
resources and technology; (2) the range of chemical s in mill wastewater and their interaction with
chemicals naturally present in freshwaters are t oo complex to reach conclusions; almost all
available literature on pulp mill effluent impacts is based on studies in the northern hemisphere;
(3)the Canadian studies which the CIS cites pertai n to a different pulp type, climate and aquatic
environment from the Botnia site 65. The report notes that, on the contrary, discharges and impacts
are recognized as site specific, and conclud es that: “Given the limited knowledge about
extrapolation between sites and environment types, the CIS statements should be more cautious,
and any associated conclusions and recommendations should be more precautionary.” 659
7.50. The Wheater report notes further that, under European law, the important aquatic
ecosystems near the site would probably be protect ed. It is therefore unlikely that this project
would be permitted to proceed under European law, and hence the implication that the plant would
be welcome in Europe is misleading in this context 660.
7.51. The Latinoconsult report points out that the migratory fish populations of the
River Paraná are the basic element for the recovery of the fish populations above the Salto Grande 661
dam, and that these populations have to cross the area of the effluent of the pulp mill . This
283 illustrates how the CIS systematically underestimat es the potential vulnerability of the biological
diversity of the River Uruguay in view of the po llution emanating from the mill. Furthermore, the
report goes on to note that the lower reach of th e River Uruguay is an area of reproduction of the
sardine Lycengraulis grossidens, as well as a marine catfish (Genidens barbus), and that the sector
downstream, near the cities of Fray Bentos and Gual eguaychú, is considered to be one of the most
important areas for migratory fish populations that feed in autumn and wint er or use the area as a
refuge at periods of low flow 662.
7.52. The IAEST developed a model to evaluate the long-term impacts of pulp mills on the
state and productivity of the sabalo population of the River Uruguay (for details, see Sec. 6.6 of the
656
See the Argentine report to the GTAN, p. 2, paras. 5-6. Anns., Vol. IV, Ann. 1.
657See the Wheater report, Sec. 1, p. 1. Anns., Vol. V, Ann. 5.
658See the Wheater report, Sec. 1, pp. 1-2. Anns., Vol. V, Ann. 5.

662Ibid., pp. 37-38. - 162 -
Latinoconsult report). The effects on post-recruitment mortality are potentially significant,
especially in so far as natural mortality is lowe r and the fish have a greater fidelity to the
River Uruguay. The findings of the IAEST therefore confirm the very strong possibility of the fish
populations deteriorating because of the effluents from the Orion mill ⎯ this is discussed in more
detail in Section V.
7.53. The CIS refers to low concentrations of contaminants in fish ti ssues in the vicinity of
Fray Bentos, including dioxins a nd furans, PCBs and organochlorin e pesticides, but states that
these are “all . . . below levels of concern for fish consumption” 663. However, as will be explained
in Section V, the phenomena of bioaccumulation and bioamplification of contaminants in fish have
not been dealt with satisfactorily by the CIS, a defi ciency which is all the more glaring in view of
the fact that the frequency of reverse flows has been underestimated, as described above.
284 7.54. Other aquatic life forms : it should be noted that the CIS does not consider the full
range of biological diversity which exists in the river and that, as a result, its assessment of this
diversity is substantially weakened. The range a nd size of the biological diversity of the river and
its surroundings are clearly confirmed by Annexes D and H of the Latinoconsult report.
7.55. In particular, the CIS fails to take appr opriate account of the impacts of the mills on
vertebrate species other than fish inhabiting the river and the areas affected by it. There is no
discussion of the potential impacts of the projects on ve rtebrates other than fish to the south of the
proposed mill site.
664
7.56. The potential impacts on amphibian species are not properly analysed , whereas these
could be exposed to xenobiotics in the environm ent in various ways, for example through their
permeable skin, as well as through egg or larval development taking place in water 66.
7.57. The CIS also refers to the benthic invertebrate comm unity, including the presence of
tubificid worms that are indicative of nutrient- enriched, low oxygen conditions that other species
do not tolerate. The IAEST carried out sampling at a total of 20sites and determined that the
ecological quality of the river water was between good and very good, as indicated by the presence
of particularly sensitive invertebrate taxa. Bo th sensitive organisms and others that are more
666
tolerant were found to be present .
285 7.58. According to the CIS, the phytoplankton community is limited by the turbidity of the
river, blue-green algae comprising a significant portion of it, particularly in the summer months
when algal blooms can occur. Argentina would point out that the Latinoconsult report concludes in
the light of its analyses (described in Ann. E) tha t: “nutrient concentration would not be a limiting
factor for phytoplankton growth, and any increase in the nutrients concentration in the area will
enhance algal growth, especially in the shores and bays” (p. 33 of the report).
66See the CIS, p. ES.xi and p. 3.8. Anns., Vol. V, Ann. 6.
664
The Latinoconsult report states in Sec.6.4 that therare 26species of amphibians in the area of interest,
whereas the CIS only mentions 13 species. Anns., Vol. V, Ann. 3.
665
See the Latinoconsult report, Sec. 6.4, p. 36. Anns., Vol. V, Ann. 3.
66See the Latinoconsult report, Anns., Vol. V, Ann. 3. - 163 -
Among the findings of the Latinoconsult repor t regarding plankton, the following should
also be noted:
“The Lower Uruguay River, and particularly the studied area, gathers optimal
growth conditions (pH, temperature, irradi ance, nutrient concentration) not only for
Microcystis aeruginosa, but for other cyanobacteria as well. Nutrient concentrations
should be monitored thoroughly, since any increase in their levels could induce bloom
formation. The Argentinean shore of the river is a highly vulnerable zone due to the
geomorphological characteristics of its coasts. These circumstances affect not only
the dynamics of the ecosystem, but might also have serious implications on human
health for the local populations, and their economies as well.” (P. 34 of the report.)
This is a further illustration of the shortcomings of the CIS in dealing with the vulnerability of the
River Uruguay as a receiving environment.
7.59. (g) Other forms of biological diversity : the area around the proposed mill supports a
wide diversity of aquatic birds and endangered speci es. The CIS does not deal with the effects of
the effluents on these birds, nor does it describe the full range of species that are potentially
concerned. For example, the CIS does not menti on the presence in the area of ten bird species that
286 are endangered to various degrees, including Xanthopsar flavus ⎯ endangered (or vulnerable),
667
Sporophila zelichi ⎯ critically endangered, and Sporophila palustris ⎯ endangered . The survey
offered by the CIS is limited and misleading. Argentina is basing itself on the analyses described
in Annex G of the Latinoconsult report, and on other information set out here, in order to show the
vital importance of the sector in question for a whole swathe of biological diversity in the region.
7.60. Uruguay has designated Esteros de Fa rrapos e Islas del Río Uruguay, 7km from the
site of the Orion mill, as a wetland of internati onal importance within the meaning of the Ramsar
Convention, to which both Argentina and Uruguay are parties 668. Esteros de Farrapos is
site No. 1433 on the list of wetlands of internati onal importance under the Ramsar Convention. It
is situated in the lower Section of the River Uruguay, downstream from the Salto Grande dam and
on the frontier with Argentina. Th e site consists of alluvial areas on the eastern bank of the river
and 24islands which are submerge d at high water and exposed when the waters are low. This
régime is important to control flooding and the er osion of the river banks. Raised sandbanks along
the islands and the alluvial plain have forest gr owth and, in this dynamic environment, allow both
temporary and permanent pools of freshwater to be formed 669. There have been sightings of the
near-threatened species Chrysocyon brachyurus and of several species of endangered birds: the
saffron-cowled blackbird, Xanthopsar flavus , and the seedeaters Sporophila cinnamomea ,
S. palustris and S. zelichi, the last of these being critically endangered. Most of the area is owned
by the State and used principally for extensive cattle farming during the summer, although there is
287 also horticulture, lemon-growing and coal production. The site’s main problem is that of soil
erosion, linked to poor farming practice in the adjacent areas.
667
The full list is contained in the lett er of 13Nov.2006 from Dr.Romina Pico lotti, the Argentine Secretary for
Environmental Issues and Sustainable Development, to Mr.Declan Duff, Vice-President of the IFC. See para.4 of the
response to point 1, Anns., Vol. II, Ann. 18.
66Convention on Wetlands of Internati onal Importance especially as Wate rfowl Habitat, 1971 (the Ramsar
Convention).
66The most abundant vegetation in the flooded areas consists of reeds Scirpus sp., water lettuce Pistia stratiotes,
eared watermoss Salvinia rotundifolia, ferns Azolla filiculoides, willows Salix sp., Zizianopsis bonariensis, Panicum spp.,
southern cat-tail Typha domingensis , Eryngium pandanifolium and water hyacinEichhornia spp. See the report
“Uruguay designates its second Ramsar site along the Uruguay River” by Ivan Dario Valencia, available at
www.ramsar.org/wn/w.n.uruguay. - 164 -
7.61. There are also protected wetlands on the Argentine shore and on the islands in the
River Uruguay (the wetlands of the Departments of Río Negro, Paysandú and Soriano in Uruguay,
and Gualeguaychú and the Ibicuy islands in Argentina) 670. The other designated sites in the region
are those of Potrero del Burro (or Rincón de Gallinas), about 14 km south-west of Fray Bentos, and
Bosque Nacional Islas del Río Negro, to the south of Fray Bentos. The Islas Fiscales del Río
Uruguay are situated further upstream from the location of the projects 671. For Argentina, the key
question regarding these sites is that of revers e flow, the consequences of which are unknown and
have not been assessed, especially as regards the transport of pollutants to these protected wetlands.
7.62. (h) Failure to address the effects of tree plantations on water balance : international
studies have shown eucalyptus plantations to cause a reduction in river levels of around 25 per cent
on average. One major study, combining the results of more than 600observations, has
demonstrated substantial loss of flow and an incr ease in the salt content and acidity of soils, where
afforestation has taken place. Overall, the plan tations reduced flow by 227 mm per year (covering
52percent of cases), while in 13percent of cases, the watercourses dried up completely for at
least a year 672. No account has been taken, no comment made nor any action proposed with regard
to this possible reduction of flow, which would directly affect the abundant wetlands of the
RiverUruguay. The Latinoconsult report confir ms that the phenomenon could certainly have
288 significant effects on the local water régime 67. The Wheater report considers the issue in
Section9, pointing out that: “The Sectionof the CIS... dealing with hydrological effects of
forestry, including groundwater interactions, is confused and misleading and does not draw on the
substantial body of relevant literature.”
7.63. The Wheater report goes on to discuss the findings of the CIS and notes that, while the
overall conclusion from the statement that there is greater evapotranspiration from trees than grass
is correct, its consequences ⎯ in particular the reduction in water available for run-off and
groundwater recharge ⎯ are not considered at all. The report points out that the relative effects
can be large, and that the environmental implicati ons of this can be very significant, depending on
the local hydrology and hydrogeology, and require proper assessment 67.
7.64. (i) Economic and social aspects : the river waters are used, amongst other things, for
consumption, recreation and fishing. Tourism is also important in the region. The Playa Ubici
beach, in the eastern part of Fray Bentos, can be seen from the Botnia site; the beach resort of
Ñandubaysal lies to the west-north-west, on the Arge ntine side, about 11km from the area of the
Botnia project.
7.65. Gualeguaychú, in Argentina, is a major tourist centre, attracting visitors to the local
beaches and the annual carnival, a popular traditional festival held every Saturday from 7 January
until the first weekend in March 675. Spectators come to the carnival from all over Argentina and
670The wetlands are protected by Law No. 9718 of the Provi nce of Entre Ríos. The present law was adopted in
June 2006, but follows on from the previous Law No. 8967, dating from 1955.

289 activities in the region, in particular the beach resorts, ecotourism, and sports, cultural and spa
tourism (thermal spas). This growth is illustrated by the increase of 39percent in the number of
tourist accommodation facilities in the period betw een the start of 2004 and the first half of
676
2006 . The economic importance of tourism for Gualeguaychú is described in detail in Section 7
of the Latinoconsult report 67.
7.66. The beach resort of Ñandubaysal is in the area of Gualeguaychú. The Ñandubaysal
Bay resort is flourishing, with nearly 45,000 visitors each year. Its main assets are the clear waters
of its beaches and other aesthetic factors. Eu trophication, which produces foul smells, public
health risks and unattractively coloured water, t ogether with the visual nuisance created by the
Botnia facilities on the opposite bank, will have a majo r negative effect on tourism. This fact, as
well as the economic implications of a decline in tourism, is discussed in further detail in Section V
below. From the first meeting of the GTAN, the Argentine delegation voiced its particular concern
at the damaging consequences that the siti ng of the mills could bring to Gualeguaychú 67. And in
its first contact with Uruguay on the subject of the CMB mill, CARU itself highlighted the problem
of the mill’s impact on tourism, a point referred to in Chapter II.
290 Section III
Typical environmental impacts of this kind of pulp mill
7.67. World pulp production is currently es timated at around 175million tonnes per year.
The mills involved are mostly situated in North America and Europe, but in recent years, producers
have sought to establish new mills in the southern hemisphere and in developing countries.
7.68. The proposed mill will use the bleached eucalyptus kraft pulp (BEKP or kraft) process.
This Section analyses the environmental impacts of using this type of process.
7.69. According to the CIS, the most wi dely accepted definition of “best available
techniques” (BAT), and the basic standard that h as been used for the design of the Botnia-Orion
mill, is that of the European Union, IPPC-BAT (2001) 679. The other reference standards used in
the CIS were the Tasmanian-AMT and USEPA Cluste r Rule requirements. The relevance of these
standards in terms of the best available techni ques in IPPC-BAT (2001) is discussed in further
detail in Section V below.
Inputs and outputs
7.70. The pulp mill’s main inputs are its wood supply, chemical products and water.
7.71. The mill’s main outputs are the wood pulp, energy, liquid effluents, discharges into the
atmosphere, solid waste and hazardous waste.

Production methods
7.72. The kraft process : the CIS states that the kraft or sulphate process is the dominant
pulping process worldwide, due to superior pulp strength properties, its applicability for most wood
291 species and its ability to comply with rigorous environmental standards 68.
7.73. The kraft pulping process consists of five stages: (1)wood hand ling; (2)pulping;
(3) chemical recovery; (4) bleaching; and (5) drying.
I.74. wood handling, the logs are debarked and cut into manageable sizes. In the pulping
292 stage, the wood chips are broken down into pape rmaking fibres in a cooking operation with white
liquor (sodium hydroxide and sodium sulphide). The white liquor is used to extract the lignin from
the wood fibre, in large high-pressure vessels know n as digesters. The unbleached pulp (brown
stock) is then washed. In the chemical recovery stage, after separation, the spent cooking liquor
(black liquor) is concentrated by evaporation and burned in the recovery boiler, generating steam at
high pressure to power the pulping process. The inorganic components of the black liquor are then
treated to regenerate sodium hy droxide and sodium sulphide for use in pulping. The chemical
substances are recovered in the form of smelt, wh ich is dissolved in weak liquor to form green
liquor. This is then clarified to remove contamin ated solids, known as dregs. These dregs are then
680
See the CIS, Sec. 2.5, and the European Union’s BRE F document of 2001 on best available techniques in the
pulp and paper industry, Chap. 2, p. 17. Anns., Vol. V, Ann. 6. - 167 -
washed, and the resulting weak liquor is used for di ssolving the smelt. White liquor is produced in
a recausticizing plant and returned to the digester s. The clarified green liquor is passed through a
slaker where sodium carbonate is converted into sodium hydroxide using lime. The white liquor is
clarified to remove precipitated lime mud. The lime mud is converted into lime through calcination
in the lime kiln and reused back in the slaker. The pulp is bleached in a process consisting of three
to five stages which form a bleaching sequence (delignification and brightening) ⎯ see below ⎯
and then dried and baled before being shipped.
7.75. Bleaching process: the ch681e of bleaching process is dependent on the type of pulp
involved and the destined end use . For a BEKP mill, the liquid effluents from the bleaching
process typically contribute half the effluent discharge and most of the organic load (CIS, Sec. 2.6).
293 7.76. In the past, elemental chlorine (Cl 2) was used as an acidic medium to bleach the pulp,
but this process results in a wide range of chlorinated hydrocarbons being produced, some of which
(in particular dioxins and furans) are toxic and carcinogenic. Faced with public concern as to the
effects of the dioxins, the paper industry adopted two alternative processes: ECF (elemental
chlorine free) bleaching, which uses chlorine di oxide instead of elemental chlorine, and TCF
(totally chlorine free) bleaching, using only ox ygen-based chemicals and not products based on
chlorine 682. It is also possible to use the properti es of both techniques, in a process known as
ECF-Light. The CIS describes Botnia as a leader in the adoption of TCF technologies (Sec. 2.6) 683.
It also states that pulp from the TCF process has lower yields and poorer final quality than the ECF
and ECF-Light pulps. The choice of bleaching pro cess is an important question, and no alternative
has been considered.
7.77. According to the CIS, which refers in th is context to a study carried out in 2006 by a
government agency in the Australian state of Tasmania, ne684er the TCF process nor the ECF
process emits dioxins at environmentally significant levels . This study concluded that TCF pulp
and ECF pulp had similar environmental impacts fro m air and water emissions. Both technologies
are described by the CIS as acceptable under th e Stockholm Convention, IPPC-BAT, USEPA and
all significant permitting authorities.
294 Water abstraction
7.78. The methods of treating pulp, including the kraft method, use very large amounts of
water. This has substantial environmental impact s, because of (1)the quantities of water that are
abstracted and (2)the possible damage caused to the adjacent environment. The consequences
typically include increased sedimentation and turbidity, increased water temperature, 685s of habitat
diversity, possible concentration of toxic material and lowering of water tables .

Emissions and effluents
7.79. Kraft pulp mill emissions to the atmosphe re may originate from: chip storage; the
cooking process; pulp washing; the bleach plant; bleaching chemical preparation; chemicals
recovery; evaporation; the bark furnace; the r ecovery boiler; white liquor preparation; the lime
kiln; tanks and pulp drying. The emissions cons ist mainly of products of combustion, including
particulate matter, nitrogen oxides (NO ), sxlphur dioxide (SO ) and m2lodorous reduced sulphur
compounds, commonly referred to as total reduced sulphur (TRS). Nitrogen oxides are emitted
from furnaces, as well as small amounts of dust (solid particulates) as fly ash. From the bleach
plants and preparation of bleaching chemicals, chlorine compounds may escape to the atmosphere.
(1) Liquid effluent discharges
7.80. General organic pollution and suspended solids : the main effluents from kraft pulp
processes are oxygen-consuming organic substan ces, such as lost cellulose fibre, starch,
295 carbohydrate and hemi-cellulose (or the organic aci ds resulting from their breakdown), levels of 686
which are measured by COD (chemical oxygen demand) and BOD (biological oxygen demand) .
This demand for oxygen depletes that available to fauna and flora, thus damaging wildlife near to
687
and downstream from the effluent discharges .
7.81. High levels of suspended solids can also cause problems of both water opacity and
blanketing of river or lake be ds. Severe blanketing may result in anaerobic decomposition under
the blanket releasing hydrogen sulphide into the aquatic ecosystem. Organic solids can also absorb
many of the toxins present in mill effluents, such as resin and fatty acids and heavy metals. This
can have long-term effects over a wider area as a result of bioaccumulation and transportation
through the food chain 688.
7.82. The treated effluent from kraft pulp m ills contains principally dissolved inorganic
solids or salts of sodium and calcium, and low concentrations of residual organic compounds.
7.83. Acidic compounds : these are predominantly natural resin acids. They may be
chlorinated in b689ched kraft pulp effluent. They are readily biodegradable and do not
bioaccumulate .
296 7.84. Organochlorine compounds: effluent from the bleach plant, where chlorine-containing
chemicals are used, contains organically-boun d chlorine compounds, commonly measured as
AOX. AOX is a measure of a wide range of chlorinated organic compounds. The AOX
measurement may also include polychlorinated, persistent compounds, some of which may be toxic
at low concentrations.
686
BOD is a measure of the amount of organic matter requi ring oxygen for decomposition used in the context of
organic pollution of water bodies. COD is a measure of the amount of organic matter and chemical compounds requiring
oxygen for oxidation, similar to BOD. COD is more widely used as it is a simpler procedure and includes the effects of
non-biodegradable organic matter which can account for up to half the material discharged. See the Friends of the Earth
Briefing, Glossary.

7.85. Chlorophenolics are formed in chlorine -bleached chemical pulping processes. They
are toxic, persistent and bioaccumulative, and can also transform into other compounds which are
even more so. This is probably the most h azardous chemical group in pulp mill effluents, being
690
present in higher concentrations than more toxic compounds such as dioxins . Substituting
chlorine dioxide for elemental chlorine in the bleaching process significantly increases
chlorophenolic production 691.
7.86. Dioxins are extremely toxic, persiste nt and carcinogenic. Furans are chemically
similar but an order of magnitude less toxic and less persistent. Dioxins are known to be present in
flue gases, pulp and effluent. The known effect s on fish and mammals are wide ranging. In
humans, they are suspected of causing miscarriages, birth defects, skin complaints, liver damage
and behavioural and neurological problems. Their bioconcentration through the food chain, via
692
fish, is a major concern .
7.87. Chloroform and other neutral chlori nated compounds are formed during the bleaching
297 process but in lower concentrations than chlorophe nolics. Compounds in this group are generally
non-persistent and non-bioaccumulative, but some may be moderately toxic, mutagenic and/or
suspected carcinogens. The major concern is the likely effect of human exposure to chloroform via
drinking water and air 69.
7.88. Use of chlorine dioxide, the basis of ECF bleaching, may lead to production of
chlorate. Chlorate is a powerful herbicide which can severely affect waterborne algae 694.
7.89. Other problems : some non-chlorinated chemical substances discharged from pulp
mills may also have toxic effects on aquatic organisms unless treated appropriately before
discharge. Emissions of coloured substances may affect aquatic ecosystems through decreased
transparency of water. Emissions of nut rients (nitrogen and phosphorus) can result in
eutrophication of water bodies. Individual metals extracted from the wood can also be detected in
695
low concentrations in effluents .
7.90. Effluent treatment: there are three possible levels of effluent waste treatment in pulp
mills. Primary treatment involves the mechanical remo val of suspended solids by settlement or
other means. The effectiveness of any secondary or tertiary treatment depends upon efficient
primary treatment, which itself reduces BOD and AOX. Secondary treatment uses
micro-organisms to accelerate the natural decompos ition of organic waste. The two main methods
used are aerated stabilization and activated sludge treatment (AST). These are both aerobic
treatments. The efficiency of these two systems varies widely, depending on climate, influent
quality, pulp type, fibre source and mill practice. In ideal conditions, AST performs better at
reducing BOD and removing suspended solids. Disadvantages of both methods include high
298
energy consumption and production of sludge waste. However, newer anaerobic treatments are

696
now coming into use . As pointed out in 697 Wheater report, AST is not designed to remove
nutrients, which requires tertiary treatment .
7.91. Tertiary or non-biological chemical treatments involve the use of aluminium oxide,
ferric oxide and polyelectrolytes to assist coagulation of waste in the effluents, which are then sand
filtered.
(2) Air emissions
7.92. Air emissions from chemical pulp mills are made up of particulates, hydrogen sulphide,
oxides of sulphur and oxides of nitrogen. Micro-pollutants include chloroform, dioxins and furans,
other organochlorines and other volatile organics. As with liquid effluents698he levels of emissions
are highly dependent upon the type of process technology employed .
The odour of hydrogen sulphide (rotten egg sm ell) can be a specific problem, as described
below. Argentina notes that the kraft pulp pro cess was banned for several years in Germany in the
1990s. In view of the emergence of new technol ogies for bleaching, recycling and odour control,
the process is now authorized in Germany. Bu t these developments do not mean that odour is no
longer an issue as regards the kraft pulp process.
299 (3) Solid waste
7.93. Solid waste is produced, with disposal usually to landfill, although incineration and
composting are becoming increasingly widespre ad. Dioxins and heavy metals may be
disseminated in the course of solid waste disposal 69.
Intrinsic environmental risks of kraft pulp mills
7.94 The main environmental problems caused by use of the kraft pulping method are linked
to the following issues (see also above): the impa ct of wastewater effluents (in particular the
presence of chlorophenolics and dioxins, and effluent colour); air emissions, especially of dioxins
and malodorous gases; the management of solid waste residues, and energy consumption. All
these elements have an impact on biological diversity, water quality and human health. As stated in
the European Union’s BREF document of 2001: “In Kraft pulping the
wastewater effluents, the
emissions to air including malodorous gases and the energy consumption are the centres of interest.
In some countries also waste is expected to become an environmental issue of concern.” 700
7.95. The CIS maintains that because of rapid developments in pulping technology,
environmental protection equipment and m ill operating practices through the 1990s, the
characteristics of the industry’s discharges have changed significantly too. The environmental
issues that remain are therefore said to diffe r significantly from those of the past. But new
300 difficulties have appeared, and other problems still remain, as discussed in Section V below.

7.96. Among the problems posed by pulp mills , the risk frequently described as the most
dangerous for the environment is the emission of dioxins and furans. This is of the utmost
importance. The Hatfield report describes these co mpounds as being “of significant concern to the
general public” 70. Kraft pulp mills which use chlorinated compounds in the bleaching process
(including ECF treatment) discharge organochlorin e compounds, such as dioxins and furans, both
in the form of air emissions and liquid effluents. As indicated above, organochlorine compounds
are extremely toxic, persistent, mutagenic and carcinogenic, and may cause birth defects, liver
damage, skin complaints and neurological and immunological diseases.
7.97. In the light of these risks, the “W orld Bank Pollution Prevention and Abatement
Handbook: Pulp and Paper Mills” of 1998 states that “the trend is to avoid the use of any kind of
chlorine chemicals and employ [TCF] bleaching . . . Only ECF processes are acceptable and from
702
an environmental perspective, TCF processes are preferred.”
7.98. Another key issue regarding discharges fro m state-of-the-art kraft pulp mills concerns
the collection and management of malodorous ga ses containing total reduced sulphur (TRS).
According to the CIS, TRS management is being addressed to a great extent by the implementation
of modern non-condensable gas (NCG) collection systems at both mills. However, the very low
odour threshold for these gases (5-10ppb) makes it extremely difficult to eliminate the odours
completely. The CIS does not state that these odours will not occur regularly.
301 7.99. Another issue is that of effluent col ouration, which, according to the CIS, is being
addressed by selection of modern pulping and bl eaching technologies and an extensive spills
collection system (CIS, Sec. 2.7, p. 2.28).
7.T0uel.tieervlel opment banks have long recognized the variety of adverse
impacts which pulp mills can have on the enviro703n t. Institutions such as the European Bank for
Reconstruction and Development (EBRD) , the Inter-American Development Bank, the World
Bank and the IFC all require large-scale pulp mi ll construction projects to be subjected to
mandatory environmental704pact assessments. Pulp mills are also subject to this type of procedure
under European law . The Espoo Convention of 1991 of the United Nations Economic
Commission for Europe on environmental impact assessment in a transboundary context also lists
pulp and paper manufacturing of 200 air-dried me tric tonnes or more per day among the activities
70See the Hatfield report, p. 3, para. 6. Anns., Vol. V, Ann. 9.
70See the Handbook, pp. 395-396, http://www.worldbank.org.
703
Industrial plants for t(a)production of pulp from timber or similar fibrous materials; (b) production of
paper and board with a production capacity exceeding 200aidried metric tonnes per day are listed as CategoryA
projects in Ann. 1 to the EBRD’s Environmental Policy document (approved on 29 April 2003). Projects are classified as
Category A when the project receiving EBRD funding could result in potentially significant adverse future environmental
impacts which, at the time of screening, cannot readily be identified or assessed. An e nvironmental impact assessment
(EIA) is therefore required to identify and assess the future environmental impacts associated with the proposed project,
identify potential environmental improvement opportunities, and recommend any measures needed to prevent, minimize
and mitigate adverse impacts (see Sec. 16 of the Environmental Policy document).
70See Council Directive 85/337/EC, as amended by Council Directive 97/11/EC and by Directive 2003/35/EC of
the European Parliament and of the Council. Ann.I to thDirective lists the projects which must be subjected to an
assessment, and para.18 of Ann. I refers to industrial plants for the production of pulp from timber or similar fibrous
materials. - 172 -
requiring notification of affected States par705s, where this manufacturing is likely to cause a
significant adverse transboundary impact .

also covered by the European Union’s rules on integrated pollution prevention and control
(IPPC) 70.
Section IV
The operating method and discharges planned for the Orion mill
7.102. The general features of the proposed m ill are summarized in Table 2.2-1 of the CIS.
The table shows that the production of air-dried pulp from the Orion mill will be 1,000,000 tonnes
per year. This figure demonstrates the scale of the project, since the average production from a
707
European pulp mill is 180,000 tonnes per year . The table also indicates that production from the
Orion mill is due to start in 2007 and has a projected 40-year lifetime.
7.103. The same table states that the Ri verUruguay will provide the water supply and
receive the effluent from the industrial operations.
7.104. The Orion mill will be constructed on a greenfield site to produce bleached eucalyptus
kraft pulp (BEKP). Botnia is the second-largest pulp producer in Europe. The mill will be
supplied with wood by Botnia’s partner, Forestal Oriental S.A., w708h is using plantations in the
Paysandú region, around 200km north-west of the mill site . The effects of eucalyptus
plantations on the water balance have been discussed in Section II above.
7.105. The project proposed by Botnia involves the construction, commissioning and
303
operation of a cellulose production plant and a port terminal in a free zone near the port of
FrayBentos, on the RiverUruguay. Each of these components is subject to prior environmental
authorization under Uruguayan law, which was granted by Uruguay in breach of the 1975Statute
(see Chaps. IV and V above). A number of elemen ts associated with the project also require prior
environmental authorization, which must likewise be in accordance with the 1975Statute. This
applies to: an effluent discharge station on the RiverUruguay; a site for the final disposal of
3
potentially hazardous industrial solid waste; a large-scale effluent treatment plant (73,000 m /day);
an electricity generating plant, and other comp lementary plants for the production of chemical
inputs (hydrogen peroxide and sodium chlorate) 70. Uruguay’s inability to carry out an appropriate
assessment of the “chemical island” that will form the core of the project is discussed in Section V
below. The central fact remains that on 14Fe bruary2005, when it unilaterally authorized the
Orion project, Uruguay did not possess all the necessary information.
70Pulp and paper manufacturing of 200 air-dried metric tones or more per day is listed in App.I to the
Convention, para. 13.
70See Council Directive 96/61/EC as amended, Ann. I, para. 6.1.

Anns., Vol. VIII, Anns. 3 and 5.
70The project is summarized in the DINAMA report of Feb. 2005, p. 1. Anns., Vol. V, Ann. 8. - 173 -
7.106. Several factors indicate the scale of the Orion project. Should the plant begin
operating, some 150,000tonnes per year of chem ical inputs will be received for industrial
production, solids and liquids, as well as possibly heavy fuel oil. The final products,
900,000tonnes per year of pulp bales, will be lo aded onto barges destined for a transhipment
terminal in Nueva Palmira. The new port will consist of two wharves for vessels, with their
corresponding operating areas and three dolphins to f acilitate mooring of large vessels, together
with an area reclaimed from the river for the collection and circulation of loads 710. The mill will
304
have an annual production capacity of around 1,000,000tonnes of air-dried pulp (ADt/a). The
projected consumption of water from the River Uruguay, which will be subject to physico-chemical
treatment before being used in the production process, is 1,000 L/s.
7.107. Site selection: the Orion mill is to be construc ted at Fray Bentos. Argentina has
received no satisfactory explanation of the criteria u sed to select the project site, in particular the
environmental criteria. This information was requested by Argentina through CARU and the
GTAN, but was never communicated to it before the publication of the final CIS ⎯ a document
whose serious shortcomings are discussed below. Neither the environmental impact assessment
supplied by Botnia nor the report published by DINAMA addressed this question. The Uruguayan
Government simply refused to discuss the matter when it was raised by Argentina in CARU and
the GTAN. Argentina asked several times about alte rnatives to the site selected, pointing out that
the failure to discuss the choice of site in the two environmental impact studies was a breach of the
711
international standards for environmental assessment . The Hatfield report also refers to the
inadequate discussion of the issue of site selection in the CIS:
“The CIS does not provide a clear unde rstanding of the site selection process
employed by Orion . . . Many stakeholders have commented on this oversight. There
is a desire on the part of the stakeholders to have an unambiguous ‘roadmap’ of the
712
decision process that governed elimination/selection of potential mill sites.”
The Hatfield report goes on to recommend that Bo tnia should outline the detailed rationale and
“decision tree” used when scrutinizing a given site for acceptance as a pulp mill location. This has
still not been done to date.
7.108. The question is only dealt with at last in Section2.3 of the final CIS, where it is
305
addressed in a very unsatisfactory way, using an approach which is not objective. The terms of
reference of the CIS team 713merely state that Uruguay is one of very few locations in the world
where already existing plantations can supply the raw material for a new pulp mill of this scale.
Argentina notes that these plantations are areas wh ich have been planted, and in no case woodland
areas existing in a natural state. Throughout the CIS, Botnia’s statements are simply accepted at
face value, and there is no discussion aimed at comparing the environmental relevance of the site(s)
chosen with that of other alternatives (i ncluding abandoning the mill project). The
recommendations of the Hatfield report calling for the reasons for the choice and a “decision
tree”
to be provided have not been followed. That is a major shortcoming attributable to Uruguay.
7.109. The CIS states that Botnia (and ENCE) decided to develop their pulp mills in
Uruguay because of its forestry policy, natural resources, trained human resources, and social,
71Ibid.
71See the Argentine report to the GTAN, p. 7. Anns., Vol. IV, Ann. 1.

71See Ann. H of the CIS. Anns., Vol. V, Ann. 6. - 174 -
political and economic stability 71. Proximity to existing plantati on operations and deep navigable
waters are described as having been the most im portant factors in the decision, in terms of
infrastructure and logistics. The CIS deals with a number of environmental aspects of the
project ⎯ such as water supply, waste management, aesthetic drawbacks, air emissions, sensitive
natural or cultural areas and acceptance of industry ⎯ but does not examine at any point how these
environmental aspects influenced the decision to locate the mill at the proposed site. The report
merely states that Botnia took account of the cultural importance of Ñandubaysal, in Argentina, and
306 Las Cañas, in Uruguay, in its site selection pro cedure. However, Botnia’s final decision only took
account of the proximity of recreational areas situ ated in Uruguay, and clearly underestimated (or
simply ignored) the importance of the Argentine part of the region affected by the project 715.
7.110. The procedure for selecting the site for the pulp mill was based on a subjective
methodology, and no criteria relating to the natu ral environment (aquatic or terrestrial) were
explicitly applied. The micro-scale site selection process (i.e., at detailed local level) was carried
out with priority being given solely to economic, logistic and construction criteria, so as to reduce
the cost of the project and facilitate industrial operation.
7.111. The SWOT analysis method was used in the site evaluation procedure, but its
application was clearly skewed by the eight crite ria applied, seven of which were economic or
logistic and focused on the concept of industr ial development (wood suppl y, energy and water
inputs, transport and proximity to towns), the last one being social (Table 2.3-1 of the CIS). It was
only after the location for the project had been chos en, solely on the basis of these criteria, that a
justification of the choice of site was a ttempted on environmental grounds. While social
considerations may have been taken into account , the environmental criteria were mentioned in
passing but never analysed explicitly or in detail. The appropriate method of site selection should
have been to quantify the variations between si tes in terms of the most important social and
environmental factors, to determine the most sen sitive areas (sensitivity maps, ruling out certain
areas) and to identify alternative sites, allowing an acceptable final selection to be made on the
basis of strict environmental criteria combined w ith economic and social c onsiderations. All this
simply did not happen. The site selection procedure was completely inappropriate, since it was not
based satisfactorily ⎯ if at all ⎯ on environmental criteria. In particular, no account appears to
307 have been taken of the effects of discharging pollutants into the River Uruguay at this point, or of
the socio-economic implications of the project fo r the Argentine side, for example in terms of
tourist and recreational activities.
7.112. The pulp mill and production methods: the Orion proposal is for a bleached kraft pulp
716
mill with an ECF-type bleaching plant ; it will operate using kraft pulp processing methods as
described in SectionIII above. This means that the mill will use chlorine dioxide as a bleaching
agent rather than elemental chlorine. It will al so use caustic soda, oxygen, hydrogen peroxide and
sulphuric acid as chemical agents in the bleaching operations.
7.113. The Orion mill project also includes the construction of two chemical input
production plants: one will produce around 70-80 tonnes per day of hydrogen peroxide, the other

sodium chlorate from br717. The two plants will produce more chemicals th an are needed for the
operation of the mill .
7.114. The electricity generating plant for th e Orion mill will consist of two steam turbines
supplied by a line with steam produced by the heat obtained in the recovery boiler, principally
through the combustion of black liquor and odorous gases. The plant will produce a surplus of
energy.
7.115. The mill will recycle filtrates within the bleaching plant, which is seen as reducing
308 water consumption and effluent flow, and thus reuse chemical residues within the plant 718.
Waste and discharges
7.116. The mill will produce large quantities of in dustrial effluent and waste. Details of the
effluents produced and how they will be treated, to gether with the proposed treatment methods, are
719
set out in the initial environmenta l impact assessment for the mills . This Section indicates the
scale of the discharges and emissions from the m ill, as these are described by the company behind
the project. The nature of the discharges and the environmental impact of the mill are discussed in
detail in Section V, in the light of the criticisms of the initial environmental impact assessments and
the provisional version of the CIS. A critical anal ysis of the impacts identified in the final CIS is
also contained in Section V.
7.117. In order to dispose of the solid wast e, proposals have been drawn up for a landfill at
Cañada de los Perros. The initial environmenta l impact assessment states that this will be
constructed in accordance with European Union guidelines. It is estimated that some 49,500 tonnes
of solid waste will be sent there every year 72. Over a 40-year period, this means that
approximately 2,000,000tonnes of solid waste w ill be generated and require disposal. No
environmental impact assessment appears to have been produced for this waste disposal facility.
309 7.118. The effluent treatment plant which form s part of the project will have the capacity to
treat some 73,000 m per day, most of which will be the result of pulp bleaching 721. The mill will
use the activated sludge tr3atment (AST) process, which will treat an average discharge flow of
approximately 73,000 m per day.
7.119. According to the CIS, effluent will be discharged into the river through an outfall pipe
lying at an average depth of 8.25 m at low water. The outfall pipe will end in a 200 m diffuser with
80nozzles (DN250), aligned perpendicular to the shor e. The discharge area is located upstream
from the port terminal on the eastern edge of the project site. At and around the mouth of the
Yaguareté, on the western edge of the Orion premis es, there is an area of shallow water (less than
two metres in depth) with a system of currents that tends to favour the deposition of sediments.

720According to Botnia’s report, 29,500 t/yr will go to landfill. The rest will be sent to the plantations (7,800 t/yr)
and the municipal dump (3,150 t/yr), and third parties will deal with the treatment of hazardous waste (150 t/yr). See the
EIA by Botnia.
721See the DINAMA report of Feb. 2005, p. 4. Anns., Vol. V, Ann. 8. - 176 -
7.120. The initial environmental impact assess ment produced by Botnia indicated that the
impact of the accumulation of sediments as a con sequence of the port structures would be limited
and relatively small, but DINAMA has pointed out th at the EIA contradicts itself as to the impact
that the terminal will have on the fish in this area 72. The questions of sedimentation and the
contamination of fish are discussed in Sections II and V.
Section V
The effects of the construction and operation of the proposed mill on
the environment of the river and the areas affected by it
General assessment
7.121. This Section deals with the environmental and related impacts of the mill by carrying
310
out a critical analysis of the conclusions of the fi nal CIS and other relevant sources of information,
in the light of independent expe rt opinions which Argentina has received. A point which all the
issues discussed in this Sectionhave in common is the general question of establishing precisely
what impact the project will have on the present users of the river, taking account
of the
environmental consequences that are being analysed here. This question stems directly from the
requirements laid down by the 1975 Statute, in par ticular the procedures that are required for plans
“which are liable to affect . . . [of the river or] the quality of its waters” (Art. 7), and the obligation
“to protect and preserve the aquatic environm ent” and “prevent its pollution” (Art.41 (a)). It is
also directly linked to the terms of IFC Operational Policy 7.50, which requires that projects should
not cause “appreciable harm” to other riparians. Lastly, as will be shown below, the risks
associated with the transporting of chemicals by ba rge have not been dealt with appropriately by
Uruguay.
7.122. The Orion mill is large enough to affect the RiverUruguay. It also clearly follows
from the obvious shortcomings of the authoriza tion procedure that Uruguay has not fulfilled its
obligations to ensure that the Orion mill w ould cause no damage to the RiverUruguay and the
areas affected by it, and in particular to the people living around the site ⎯ which was selected
unilaterally, in breach of the 1975 Statute ⎯ especially those engaged in tourist activities or fishing
(whether recreational or for subsistence). The Latinoconsult report confirms that it is highly
probable that the fish populations and the diversity of the ecosystems will be degraded, and that
723
algae produced by eutrophication will appear and spread more frequently . Argentina regards this
as significant damage, resulting from harm caused to the ecosystems in the areas around the mill.
311 Furthermore, the Latinoconsult report concludes that there is an increased risk of pollution when
the mill shuts down and restarts (a risk which has not been assessed quantitatively by the CIS), that
an emergency basin is not of the appropriate size, and that the lack of a tertiary treatment plant is
unacceptable 724. The major environmental impacts that w ill lead to appreciable damage include in
particular: the accumulation of sediments and ass ociated contaminants in Yaguareté Bay, with
implications for the food chain and trophic status; an increase in eutrophication and the appearance
and spread of algae, due to the higher levels of phosphorus and other nutrients; the generation of
unpleasant odours over an extensive area; and an in creased risk of chemical spills, especially
involving river barges.

7.123. The detailed grounds for this general as sessment of the substantial adverse impacts of
the project will be set out in the remainder of this section.
Methodology of the CIS: the reference to BAT (best available techniques)
7.124. The CIS concluded that the pulp m ill implements the recommendations of the best
725
available techniques (BAT) . However the project complies with BAT in other respects, it is
quite clear, as explained below, that the mill does not comply with BAT as regards the lack of
tertiary treatment and of appropriate emergency basins. In any event, Argentina rejects the
conclusion which the CIS appears to draw from th is, namely that compliance with BAT standards
312 means that the mill will have no significant impact on the environment 72. As the Latinoconsult
report points out:
“Any responsible environmental analysis must, as the FCIS has done, consider
the current regulatory requirements such as standards for discharge and ambient water
quality, and standards for BAT. However, adherence to such standards does not in
itself guarantee that there will be no environmental effects. Standards for BAT are set
to provide the best possible level of environmental protection that is commercially
feasible and as such do not necessarily reflect the absolute best protection that is
technically feasible (European Union Council Directive 96/61/EC ⎯ Article16,
Section2). While emission and ambient environmental standards are usually set
conservatively and based on the best available information, they are from time to time
revised to reflect knowledge about the significance of environmental effects.” 727
7.125. It is important to note from the outset that the European BAT standards do not cover
all the environmental problems associated w ith pulp mill operation. The BREF2001 document
thus states that:
“Neither environmentally relevant upstream processes like forestry
management, production of process chemicals off-site and transport of raw materials
to the mill nor downstream activities like pape r converting or printing are included in
this document. Environmental aspects whic h do not specifically relate to pulp and
paper production such as storage and handling of chemicals, occupational safety and
hazard risk, heat and power plants, cooling and vacuum systems and raw water
treatment are not or only briefly treated.” 728
7.126. The Latinoconsult report rightly insists on the fact that, even if they are implemented,
313
the modern techniques advocated by BAT do not elim inate all the effect729n the environment. The
specific issues to which the report draws attention are as follows :
725
See the CIS, p.ES.iv. Overall, the CIS states that Botnia has developed fibreline (and complete mill)
configurations “that would be welcomed in Canada, the USA or Europe”, and which are likely to perform better than any
of their existing mills with respect to environmental perform ance. The selection of two-stage oxygen delignification,
ECF-Light bleaching and the cautious approach to alkaline filtrate recycling is said to be consistent with BAT. It is
claimed that the expected performance with respect to bleach ing effluent flow, COD content and colour will be among
the best in the world. See the summary of Sec. 2.6 of the CIS, p. 2.26. Anns., Vol. V, Ann. 6.

⎯ while modernization of pulp mills has made im portant advances in reducing the discharge of
highly toxic chemicals such as dioxins and furans, these improvements have in some situations
led to new problems;
⎯ in light of the current scientific evidence, while secondary treatment and ECF technology have
helped to reduce the effects of pulp mill effluents, these improvements are not sufficient to
alleviate other problems such as the reproductive responses observed in fish 730;
⎯ there is growing concern in the scientific community that secondary treatment may cause
formation of more biologically active substances;
⎯ there is a growing body of evidence that dom inant reproductive effects may be related to
natural or generated compounds in cooking liquors and digester condensates that are not due to
the use of chlorine in the bleaching process;
⎯ Munkittrick (2004) indicates several reasons why it is not advisable to consider that current
technologies have completely solved the problem with pulp mill effluents. These include the
314 fact that some effects have persisted at sites where modernization of mills has taken place, and
that environmental impacts have been seen at mills with modern bleaching processes 731.
7.127. Even if BAT were used, their limit ations as standards which allow the potential
environmental impact of pulp mills to be assess ed must be considered alongside a number of
specific uncertainties identified by the Latinoconsult report, which should now be discussed.
The failure to take account of sci entific uncertainties as regards th e environmental impact of the
pulp mill
7.128. The CIS has not taken sufficient account of scientific uncertainties in carrying out its
assessment of the impact of the Orion mill. In many cases, it has not taken them into account at all.
This conflicts with the precautionary principle, which must be applied here both as an international
standard and by way of good practice in carryi ng out environmental impact assessments. This
skewed approach removes all credibility from the general conclusion of the report, namely that the
mill will have no significant impact on the envi ronment. Both the Wheater and Latinoconsult
reports criticize the failure of the CIS to deal appr opriately, or sometimes at all, with scientific
uncertainties. The Wheater report finds that th e CIS is not consistent with international good
732
practice in this respect , pointing out that explicit recognition and analysis of uncertainty is now
standard practice in environmental risk assessme nt. Wheater thus identifies key uncertainties
315 which need explicit treatment, such as: (1)pollu tant loads in waste streams; (2)wastewater
treatment plant performance variability; (3)low fl ow conditions; (4)the near-field dispersion
model; (5) the far-field dispersion model; (6) the fate of contaminants; (7) ecological effects.
730
See Munkittrick et al., 1997 and Munkittrick et al., 2003.
73The other reasons mentioned by the Latinoconsult report are as follows: new sites with new impacts are being
reported; reductions in effluent toxicity mean that fish can inhabit areas with higher effluent concentrations leading to
increased effluent exposure; improvements in technology that reduce some compounds that earlier masked the effects of
others can allow these effects to be expr essed; and some new studies suggest that some effluents can exert new or more
potent effects once secondary treatment has been introducedespite its benefits in reduc ing other effects). Anns.,

73See the Wheater report, Sec. 3, p. 3. Anns., Vol. V, Ann. 5. - 179 -
7.129. The Latinoconsult report, for its part, dr aws attention to a number of basic issues that
seriously threaten confident prediction of the eff ects of the construction and operation of the pulp
mill 73:
(1)inadequate delineation of the plume means th at it is not yet possible to characterize the
potential exposure concentrations that will be experienced by biological receptors;
(2) without information on the residency periods , seasonal reproductive cycles and critical periods
of development of exposed biota, which is curren tly lacking, it is difficult to predict impacts of
exposure;
(3) without baseline data on contaminant levels in fish, which is also currently lacking, it will not
be possible to separate out the mill’s contributi on to contaminant burdens from other sources.
Without this critical information, a confident prediction of risk cannot be made;
(4) prior experience shows that pulp mill effluents may have unanticipated effects. For example,
the submerged vascular plant Egeria densa and black-necked swans have been severely
impacted at (extirpated from) the Carlos Anwandt er Sanctuary, a site protected by the Ramsar
Convention downstream of a new pulp mill on the Río Cruces in Chile (Mulsow and
316 734
Grandjean, 2006) .
7.130. The Latinoconsult report goes on to discuss the uncertainty regarding the735andards
for effluent discharge that are needed to ensure environmental protection . To explore the
question of what level of effluent dilution might be needed to ensure protection of 95percent of
potentially affected species at a 95 per cent conf idence level, the IAEST us736the Kooijman (1987)
method called “hazardous concentration for sensitive species” (HCS) .
7.131. Since there are currently no studies of t oxicity of pulp mill effluents that are specific
to the River Uruguay, this analysis has been done using toxicity estimates for values reported in the
literature for effluents from mills with technology similar to that proposed for the Botnia mill at
Fray Bentos (Ann.C). The results of this analys is indicate that this level of protection would be
achieved at effluent concentrations of approxima tely 0.01percent (equivalent to a dilution of
1:10,000). This analysis, like those presented in the FCIS, is also hampered by a relative lack of
data on the chemical properties of eucalyptus effluents.
7.132. It thus becomes clear, once these un certainties are taken into account as required by
the precautionary principle, that the conclusions of the CIS cannot legitimately be defended.
The CIS has not dealt with all the existing risks
317 7.133. Section3 of the La tinoconsult report discusses a number of significant risks which
have not been addressed in the CIS. These hidden risks include in particular:
733
See the Latinoconsult report, Sec. 4.6. Anns., Vol. V, Ann. 3.
734Another example concerns the reported impacts on brown algae in the Baltic Sea, which appeared as a result of
chlorate discharge only after ClO 2as substituted for elemental chlorine in older technology mills. See the
Latinoconsult report, p. 24.
735See the Latinoconsult report, Sec. 4.7. Anns., Vol. V, Ann. 3.
736This method has been developed by researchers of the National Institute of Public Health and Environmental
Protection of the Netherlands (i.e. C.J.van Leeuwen, W. Slooff, T.Aldenberg, P.C. Okkerman, E.J.V.D.Plassche,
H.J.B. Emans, J. H. Canton and others; see van Leeuwen, 1990). - 180 -
⎯ the risk of chemical accidents during transport of supplies on the RiverUruguay, given the
increase in traffic and cargo on the river;
⎯ the risks associated with on-site chemical manufacture.
7.134. This deficiency is further proof, al ongside the failure to take account of scientific
uncertainties and undue confidence in meeting BAT requirements, that the conclusions of the CIS
can in no way be seen as based on sound foundations.
7.135. As regards the risk of chemical accide nts in the form of spills during transport of
supplies on the RiverUruguay, the CIS indicates that chemical and other supplies will be
transported by barge to the pulp mill 737. The Latinoconsult report notes in this respect that it is
fairly common practice in environmental assessment to deal with some related activities separately,
although this is not always desirable 738. The movement of chemical supplies on the River Uruguay
could, in the event of an accident, have serious consequences for water quality in the river. The
Wheater report criticizes this shortcoming of the CIS, which does not fully address the risks of
accidental pollution, pointing out that accidental chemical spills from barges or road transport have
318 not been considered 739. The report also criticizes the fact that no attention has been given to
chemical accidents resulting from flooding of the wastewater plant.
7.136. As regards the risks associated with on- site chemical manufacture, Botnia states that,
in addition to the production of ClO 2, it will have three chemical production plants: for sodium
chlorate, concentrated sulphuric acid and methanol. These plants are presented as the ones that will
740
furnish the pulp mill with the necessary chemicals . However, the production capacity of the
plants will be much greater: 15,000tonnes/year of hydrogen peroxide, 60,000tonnes/year of
sodium chlorate and 65,000tonnes/year of oxygen. These figures show that most of this output
will be exported, so that the production and stor age of these chemicals fall under the concept of
“chemical island”, i.e., a separate production and business unit, particularly because the operator
will probably be a third party (Kemira). In any ev ent, however, Botnia retains its responsibility in
relation to emissions and discharges from this “chemical island”.
7.137. There is no separate environmental impact analysis of the “chemical island”; nor is
its environmental impact discussed in the genera l environmental impact assessment. The worst
aspect of this omission is that, besides the very serious environmental issues raised by these
chemical production plants, there is no separate risk evaluation for them (for discharges and
dispersions, inflammable products, fire risks, etc.), nor are there any contingency or emergency
plans. No consideration has been given to possible preventive measures aimed at containing a
319 chemical accident or reducing the seriousness of th e damage that might be caused. Flooding or
seismic risks have also not been considered. In short, the chemical risks have not been properly
assessed.

74These supplies are given as 7,000 tonnes/year of hydroge n peroxide, 12,000 tonnes/year of sodium chlorate
and 20,000 tonnes/year of oxygen. - 181 -
7.138. Moreover, Botnia’s proposal clai ms to apply BAT standards for the pulp mill
processes, but in contrast no reference is made to BAT standards for the management, handling or
internal transportation of stocks of the various input products 741.
7.139. Argentina would point out that so me pulp mills, for example the Gunns mill in
Australia, which the CIS refers to frequently as a model, also manage large amounts of chlorine,
solutions of chlorine dioxide, hydrogen peroxide, oxygen, sodium chlorate, acetylene, etc. These
mills apply an emergency and risk management system for these production units. In these
systems, discharges and dispersions, inflammabl e products, fire risks and other impacts are
subjected to risk identification, and particular a ttention is paid to dangerous substances, assigning
higher significance to those that may potentially im pact away from the process site. Models are
used to evaluate the possible toxic effects of re leases, discharges, dispersions, possible fires and
742
explosions. There is no similar approach to the Orion mill’s “chemical island” in the CIS .
7.140. Argentina also notes that, as pointed out by the Latinoconsult report, there are special
risk management requirements for industries th at fall under USEPA’s Progam3 processes, the
320 most potentially dangerous of industries. In these cases, the owner or operator must submit a single
risk management plan that includes the required information for all the processes in use at that
facility. The risk management plan should ther efore contain relevant information about each
process.
Methodology of the CIS: the use of computer modelling
7.141. The CIS refers to the fact that it uses “sophisticated, internationally accepted
743
computer modelling techniques for the analysis of air emissions and effluents to water” .
However, the modelling techniques on which the CI S relies, especially with regard to plume
dispersion, have not been able to paint a full pi cture of the likely environmental impacts of the
construction and operation of the Orion mill. Th e general conclusion of the Wheater report on the
hydrodynamic and water quality modelling is th at: “The modelling is poorly presented,
inadequately detailed, not transparent, not suffi ciently supported by experimental data, and the
744
confidence placed in the models is unjustified and misleading.” And the Wheater report goes on
to level a series of criticisms at the approach to modelling in the CIS, as set out below.
7.142. Water quality : the methodology used to assess water quality is described in
Section4.1.3.2 of the CIS. The assessment of water quality and related impacts of pulp mill
effluents on the River Uruguay involved modelling of effluent dispersion in the river to determine
321
resulting concentrations of each effluent constituent, for comparison to water quality guidelines and
existing baseline concentrations 74. Two types of mathematical models were used by the CIS:
near-field models, which predict water quality changes near to the point of effluent discharge, and
far-field models, which predict these changes farther from the point of discharge.
7.143. Argentina has already pointed out that the methodology used by the CIS is seriously
skewed in several ways: the frequency of reverse flow is substantially underestimated; the plume

74See the CIS, p. 4.9. Anns., Vol. V, Ann. 6. - 182 -
dispersion model is plausible, but the descripti on of the modelling is too vague. There is no
explanation of the use made of 2D and 3D models, and the consequences of a possible shift to a dry
weather cycle are not dealt with. The significance of these shortcomings for the environmental risk
assessment has been discussed above.
7.144. The baseline water quality conditions, which were taken from Algoritmos (2006), are
described as average concentrations of key water quality parameters based on five water samples
collected at each of ten river locations in 2005, under near average flow conditions. It is stated that
these locations ranged from upstream of the proposed CMB discharge to Balneario Las Cañas.
7.145. The CIS utilized two near-field models . The Cormix model, developed by Cornell
University, was used as the primary modelling t ool. The VPlume model, distributed by the
USEPA, was used to provide a cr oss-check on the Cormix model results “to ensure that the
analysis was valid and conservative”.
322 7.146. The Wheater report points out that the Cormix model “although well-used and
previously proven to be useful in many circum stances, has limitations for complex channels and
tidal-flow interactions, and caution must be used wh en interpreting results”. The report refers to
the World Bank, which has noted on several occasi ons the need to be cautious about using model
results in general746. The Bank has also noted that significant programmes of data collection are
generally required to support modelling, especia lly when complex models are used, like those
employed within the CIS. In this context, the data collection within the CIS is clearly inadequate to
support the models used 74. The report goes on to state that the near-field modelling has employed
two different, well-recognized models, Cormix and Visual Plume, but that the CIS has not reported
the differences in results between models and is not explicit about the assumptions employed. The
far-field modelling (see below) should also include model intercomparison 74.
7.147. The far-field modelling was performed using the TABS-MD series of models,
available from the US Army Corps of Engineer s. Specifically, RMA-2 and RMA-10 and their
implementation are described in Annex D of the CIS.
7.148. The calibration of the far-field hydrodyna mic model is described by the CIS as being
based on water elevation data during two different periods and under different flow conditions. It
was concluded that the hydrodynamic model accurately predicted flow dynamics along the
River Uruguay below the Salto Grande dam (p. 4.10 of the CIS).
323 7.149. The Wheater report notes that the far-fi eld model has been calibrated and verified to
water levels at a few locations for a limited dura tion, pointing out that this does not verify the
2-Dhydrodynamics, which can only be done satis factorily using surveys of river velocity
(magnitude and direction) as well as depths. The report states that the t echnology for surveying
river velocity is available, and that it is not cl ear why this technology was not employed as part of
the impacts analysis. It also states that ADCPs should at least have been used to verify the currents
for the near-field simulations, which was done for the dispersion analysis in the environmental

impact statement for the proposed Gunns pulp mi ll in Tasmania, and has been used to support
749
hydrodynamic analysis of various rivers and estuaries .
7.150. Likewise, the Wheater report points out that, while an internationally recognized set
of models has been used for both near-field and far-field modelling of pollutant dispersion, “this
type of model and this type of application are recognized as being limited by the assumptions used
about parameters, physical processes and boundary cond itions”. It goes on to say that a particular
issue arises here with the effects of flow reversal in the estuary, and the effect of wind in enhancing
those effects. The modelling of these effects is difficult; the associated uncertainty should be
recognized and the sensitivity of plume behaviour should be assessed 75. However, the CIS has not
seen fit to meet these requirements.
7.151. The Wheater report makes a series of fu rther criticisms of the approach to modelling
324 in the CIS, for example: the mistake of not co mmissioning an up-to-date bathymetric survey; the
erroneous assumption that Manning’s coefficient was uniform in the whole lower reach of the
river, whereas the channel roughness is potentially variable over the length and width of this reach;
the use of dispersion coefficients taken from an unpublished study of bacteria concentrations which
have not been verified or properly justified; no information is provided on the finite element grid;
no transient modelling has been done, which woul d have allowed a fuller analysis of tidal
dynamics, including reverse flow events; no tracer tests have been carried out prior to the start of
mill operation.
7.152. Taken together, these criticisms and the other points raised above lead to the general
conclusion that the approach to modelling in the CIS is seriously deficient. Yet this is a key
element in assessing the impact of effluents and discharges of pollutants.
7.153. The CIS states that the physical and chemical characteristics of the effluent discharges
were provided by Botnia 751 and multiplied by 1,000,000 AD tonnes/year for the Orion mill. It also
indicates that the modelling was completed for di fferent river flow and effluent discharge
scenarios, including river flow reversal (described as “rare”). For each of these scenarios, water
quality results were considered at specific “river locations of interest”, two of which were in
Argentina (Receptor10, RiverUruguay on the Arge ntina side, and Receptor11, beach area at
Ñandubaysal, Argentina). Argentina takes the view that other locations in Ñandubaysal Bay, the
Inés lagoon and on the Santa Inés islands should have been included, given the sensitivity of these
sites.
Air quality/emissions
325 7.154. As recognized in the draft CIS, air emissions and air quality are of significant concern
across a broad area because gas emissions from a pulp mill have the potential to be spread most
widely in the geographical area of the project 752.

7.155. In February 2006, the Argentine report to the GTAN noted that DINAMA had been
highly critical of the environmental impact assessm ent provided by Botnia, especially with regard
to gas emissions 753. Among the cases where the information in this assessment was found to be
inadequate were the absence of data on volatile organic compounds (VOCs), the lack of detail on
the type of particulate material emitted, and the fa ilure to address the question of the opacity of the
discharges. The environmental impact assessment also did not explain precisely how the estimates
had been produced, how the emission factors had been obtained, or how the mill had been designed
in order to achieve the projected levels 754.
7.156. Ambient air quality : the CIS indicates that the one-hour concentrations it refers to
represent the highest concentration predicted dur ing the one-year simulation, while the annual
average concentrations represent the average for that year (see the CIS, p. 4.34). It states that for
normal operating conditions, variability is depende nt on meteorological conditions only, whereas
for upset conditions, variability is also dependent upon the occurrence of the upset event relative to
the meteorological conditions (see p. 4.34).
7.157. The findings of the final version of the CIS were that air quality remained in
compliance with ambient air quality criteria unde r all meteorological conditions and operating
conditions, and at all receptor locations. It infers from this that there is no “potential for human
326 755
health effects associated with mill emissions” . Hence the CIS concludes that there is no
possibility of effects on human health as a result of mill emissions at any of the ten receptor sites,
including the three in Argentina (see Sections 4.4. 1-4.4.10). It concedes that it is possible that
odour may be detected on occasion (less than ten tim es per year) within the areas adjacent to each
mill and possibly within the city of Fray Bentos and at the international bridge (see Section 4.4.11),
and under upset conditions, as discussed below.
7.158. Argentina expressed its concern to the GTAN at the fact that the impacts of emission
peaks that might occur through unexpected inci dents or programmed maintenance stoppages had
not been taken into account in the assessment process 75.
7.159. The IAEST took the view that, while it w as possible to state that these impacts could
be expected to remain within the limits set for daily effluent discharges, the CIS did not address
this particular issue in a quantitative way, and that it also failed to indicate the time of year when
these stoppages would be most likely to take place.
7.160. Dioxins and furans : the Argentine report to the GTAN also expressed Argentina’s
concerns at the high levels of dioxin a nd furan emissions authorized by DINAMA 75, and at the
lack of provision for monitoring. The Argentine delegation likewise voiced its concern in view of
their power of bioaccumulation, which could lead to increased concentrations in the longer term 758.

327 7.161. Odour: the emission of unpleasant odours by pulp mills is a widely recognized
problem and a source of concern for public opinion. The CIS found that nowhere in the area, in
particular at Gualeguaychú and Ñandubaysal, w ould any odour generally be detected during
759
normal mill operations . However, odours might be detected at locations near to the mills during
what are termed “upset conditions”, on initial st art-up and at times of poor air dispersion.
According to the CIS, operating experience at ot her mills indicates that these occurrences will be
limited to less than ten times per year, lasting for minutes to hours during the first year of operation
and for seconds to minutes thereafter. The report states that:
“During these limited events, the odour at the nearest receptors... may be
considered objectionable at times to someone with a sensitive sense of smell. At...
beach resorts... odour, if detectable during these limited events, may not be
760
distinguishable from odours experienced in daily life.”
7.162. The question of odour is not just a matter of discomfort or poor quality of life. All the
total reduced sulphur (TRS) compounds responsible for the odour are toxic for the respiratory
system. An epidemiological study of the public health effects of TRS emissions from pulp mills
has shown that eye and nose symptoms and coughing were more frequent in individuals exposed to
761
levels above 0.07ppm (as a daily average) than in individuals not exposed to TRS emissions .
These symptoms are similar to those reported from exposure to hydrogen sulphide (H 2S). Other
epidemiological studies carried out in Finland in populations exposed to high levels of TRS
762
328 emissions have demonstrated similar results . The South Karelia air pollution study, distributed
in the form of a questionnaire for self-completion, found that individuals in the populations
exposed to TRS presented more symptoms of cough ing, respiratory infections and headaches than
the non-exposed populations. In particular, the re lative risk of headache was significantly greater
in the exposed populations. A 1992 study by Haahtela et al763found that cases of ocular and
respiratory symptoms were more numerous during periods of exposure to levels above 0.025 ppm
(as a daily average) than in a reference period.
7.163. Ozone: the CIS has simply not deemed it rele vant to mention the likely emissions of
ozone. The United States Environmental Protecti on Agency (USEPA) requires ozone emissions to
be documented systematically when pulp and paper industries produce 100tonnes per year or
more, an approach which has proved economica lly beneficial in terms of protecting the
environment. Given the planne d production volumes, the Orion mill should therefore also be
obliged to account for its emissions of ozone.
7.164. The CIS states that the Botnia m ill will meet and exceed IPPC-BAT (2001) and
Tasmanian-AMT (2004) measures to control odorous gases from the recovery boiler and kiln,
including efficient combustion control and CO measu rements in the recovery boiler and control of
excess oxygen and residual sodium sulphide in the li me kiln. The mill is described as having “an

extensive and comprehensive dilute gas collecti on system” and as using the recovery boiler as the
primary point of incineration. According to the CIS, the provision of a back-up for the dilute gas
329 system and also the inclusion of white liquor preparation sources goes significantly beyond the
IPPC-BAT (2001), Tasmanian-AMT (2004) and USEPA (MACT) requirements 764.
7.165. Argentina’s general comments on the re levance of using BAT have been set out in
paragraphs 130-133 above. With regard to odour , the CIS seems to deliberately try to play down
the impact that odours will have on people in the surrounding areas, assuming that the odours
released will be no more disturbing than those enco untered in everyday life. Argentina believes,
and would maintain, that the CIS assessment in th is respect is based on subjective assumptions and
unfounded statements which ignore the established im pact of odours in the vicinity of other areas
that have been affected by pulp mills.
Water quality
7.166. Baseline data and parameters for efflue nts: Argentina would point out that there is
currently no other pulp mill on the banks of the Ri ver Uruguay, and that no other industrial facility
discharges into its waters even a fraction of the volumes of liquid pollutants that are planned.
Argentina maintains that Uruguay has neglected to obtain appropriate baseline data on water
quality, and failed to make a satisfactory assessment of the capacity of the river waters to receive
and disperse the planned discharges of pollutants.
7.167. It should also be noted in this cont ext that the final version of the CIS changes the
values for most of the technological parameters (expressed in dried tonnes per year), which has
reduced the values for effluents to almost half of the figures announced initially in the first CIS.
No account has been given of the reasons for this change. However, if the CIS is using particularly
330 conservative estimates, this should be expressly st ated. In the absence of clarification, this
unexplained difference can only call into question once again the validity and reliability of the
findings of the CIS.
7.168. The concerns of Argentina : the Argentine report to the GTAN raised a series of
concerns regardi765the damage to the watercourse that might be caused by discharges from the two
proposed mills , and these may usefully be summarized below.
7.169. With regard to COD, while noting that the USEPA is actively encouraging the
authorities that grant discharge permits to set discharge limits on COD in the sub-categories kraft
and caustic soda, the Argentine delegation decl ares that it is essential for these limits to be
established, because sub-lethal toxic eff766s resu lting from the discharge of treated effluents from
kraft pulp factories have been found . For AOX, the principal damage is associated with the
evident presence of toxic chlorinated compounds. The report points out that a relationship has been
observed between AOX and specific pollutants, incl uding dioxins, furans and chlorinated phenolic
compounds. The potential formation of such polluta nts will exist in the pulp and paper industry as
long as it uses any compound containing chlorine ⎯ including chlorine dioxide ⎯ in the bleaching
process 767. The report notes that the RiverUruguay is an ecosystem which is free of AOX at

76Ibid. - 187 -
present, or with AOX values below the detection limit, and that these compounds will either
accumulate in the ecosystem (fish) or w ill dilute in it. With regard to phosphorus nutrients, the
damage is associated with the a ppearance and spread of blue-green algae (eutrophication) in areas
of the river near the Argentine shore. Botnia ’s environmental impact assessment recognizes that
there will be an increase in the cu rrent concentration of phosphorus at the site, and the report notes
that the problem of eutrophication will thus become worse 768. The report also deals with the
331
impact of total suspended solids (TSS) coming from leaks in the sedimentation unit associated with
the biological treatment of activated sludge. It refers to the biological risks linked to the presence
of coliform bacteria in the ECF bleaching effluents, amongst other risk factors, and the specific risk
for iliophagous fish and detritus feeders. The report sets out the concerns regarding discharge
temperatures in relation to those of the river and the effect on the plume, which will rise towards
the surface. This question was simply not addr essed in the dilution models presented by the
769
Uruguayan delegation . The information on effluent treatment provided in Botnia’s
environmental impact assessment is also described as inadequate by the Argentine report to the
GTAN, since no information was supplied on the secondary or tertiary treatment of the liquid
770
waste . The Argentine report also criticizes the propo sed treatment system as consisting merely
of “moving easily sedimented solids in suspension and biodegradable organic matter”.
7.170. Argentina would also point out that neither Botnia nor the CIS has carried out studies
of acute or chronic toxicity with three species, as recommended by the USEPA (Argentine report to
the GTAN, p.17). Nor did the CIS see fit to di scuss the difference in temperature between the
discharges and the river water, and its effect on the plume.
7.171. The methodology of the CIS and its conclusions on water quality : there are many
serious deficiencies in the method used by the CIS to evaluate water quality: as indicated in the
Wheater report (see below), the CIS is not justified in its emphasis on the 1:100dilution
771
envelope ; it appears to take the view that there are no effects at dilution levels greater than
1:1000; it neglects the potential impact on sensitiv e areas where, according to the work of the
332 IAEST, the dilution levels will in any event be less than 1:1000; and it fails to address the issue of
bioaccumulation and bioamplification in fish, which nevertheless has major implications for the
entry of contaminants into the food chain. On this last point, it is also interesting to note that the
Argentine report to the GTAN had stressed the importance of taking account of the known and
declared uses of the waters receiving the pollutants, namely provision for human consumption with
conventional treatment, protection of aquatic life, and recreational use involving direct contact 77.
7.172. In the CIS, modelling of effluent flow s and loadings was undertaken to determine the
impacts at 11selected locations. The results we re then compared to applicable standards and
guidelines and used to estimate potential impact s on human health, aesthetics, sediment quality,
fish communities and aquatic invertebrates. Sin ce water quality is shown to remain in compliance
with these standards at all receptor locations, the CI S team concludes that “there is no potential for
773
human health, aesthetic or environmental effects associated with the mill discharges” . However,
Argentina maintains that this finding is no guarantee of safety, as there are differences in sensitivity
to exposure to some environmental factors with in the general population. Among the sensitive

population, children and embryos are the categories most at risk, even with very low but permanent
levels of exposure to pollutants and their mixtures. According to the CIS, the potential effects are
limited to the area where the effluent initially mix es with the river water, and “beyond this small
area, the water quality standards are achieved with the exception of those parameters which exceed
the standards under present conditions due to the di scharge of untreated municipal wastewater and
agricultural run-off”.
7.173. In its assessment of exposure to effl uents in the RiverUruguay, the CIS has applied
333
monitoring standards developed for the Canadian paper industry by Environment Canada (see
Section4.6.1 of the CIS). The CIS notes that Environment Canada defines areas beyond 1:1000
dilution as reference areas and considers them representative of b ackground conditions.
Environment Canada also takes the view that e nvironmental effects are not anticipated in areas
where the concentration of effluent in the river is less than 1 per cent (1:100 dilution). It is wrong
to imply, as the CIS does, that no effect on the e nvironment can occur at such dilution levels. In
any event, there are sensitive areas in which the dilution level will be less than 1:1000, as shown by
the findings of the IAEST (see below).
7.174. These criticisms are confirmed by the Wheat er report774hich states that in parts of the
CIS, there is too much emphasis placed on dilution ratios . It goes on to explain that the
1:100trigger used by the Canadian Environmental Effects Monitoring Programme, to which the
CIS refers, has not been interpreted correctly by th e latter. This trigger was primarily designed to
focus experimental resources and to avoid the need to sample in difficult and unsafe conditions.
The report also criticizes the CIS for using scien tific articles on the Canadian experience as the
basis for assertions which are not made in the articles themselves 77.
7.175. Yaguareté Bay (Uruguay) and Ñandubaysal Bay (Argentina), several kilometres away
from the discharge outfall, will have dilution ra tios of less than 1:1000 (1:516 and 1:693
respectively). The Canadian Environmental E ffects Monitoring Programme recommends rigorous
334 monitoring of areas where dilution levels are between 1:1000 and 1:100 ⎯ a recognition of the
risks inherent in such pollution. No proper syst em of sampling has been put in place, however.
Moreover, it is the BACIPS (Before-After-Control-Impact Paired Series) programme which should
be used, as this is the system most widely recommended by the international literature to determine
impacts on the environment 776.
7.176. Effects on fish : on the basis of the work of the IAEST, Argentina believes that,
contrary to the claims made by the CIS, there is a very high probability that the fish populations of
the river will be affected by the effluents discharge d by the mill. The IAEST’s estimate of the risk
of impacts on the fish populations, with the bare minimum of protection for the fauna and flora
(complete mixing of the effluents in the river cu rrent), shows the values of the Lowest Observed
Effect Concentration (LOEC) being exceeded. The LOEC threshold was exceeded at dilution
ratios of between 1:100 and 1:1000 for various levels of the final parameters measured (from
molecular and physiological level up to population le vel). This result would have been even more
pronounced for those sections of the river or ba ys with dilution ratios below the final dilution
(Yaguareté or Ñandubaysal Bays). ProfessorHowa rdWheater confirms that indicators such as
endocrine disruptors (one of the final paramete rs measured) are significant if they can be
77See the Wheater report, Sec. 2, p. 2. Anns., Vol. V, Ann. 5.

demonstrated, and that there are effects which may appear at the actual concentration values
obtained after dilution of the effluents in the river.
7.177. These results conflict with those of th e CIS, which concludes that although fish may
be attracted to areas of exposure in the receiving waters because of the warmer temperatures and
higher velocity at the diffusers, th size of this area of exposure is so small relative to the home
335
range for most fish species that, by reference to the Canadian experience, “the potential for effects
on fish is considered minimal” 777.
7.178. The CIS has not carried out any reasone d assessment of possible bioaccumulation or
bioamplification in the food of fish near the discharge sites. The report confines itself to
recommending that monitoring should be put in place.
7.179. With regard to the Ramsar site of Esteros de Farrapos, the CIS concludes that, even in
reverse flow conditions, it is practically impossible for mill effluents to affect the area of the river
delta and its islands. This conc lusion of the CIS is incorrect. The 17,500hectares of Esteros de
Farrapos extend from the 119.5 km point to around the 166 km point of the navigation channel of
the River Uruguay, thus covering a section 46.5 km in length. The plume dispersion model used in
the Latinoconsult report has the plume extending from the 70 km point to the 117 km point of the
channel. Hence the upstream boundary of the dispersion model is only 2.5 km south of the Ramsar
site. At this upstream boundary, a dilution of less th an 1:1000 is expected 1percent of the time.
The minimum dilution simulated at the boundary w as 1:200. It is predicted that, in certain
conditions, the plume could move beyond the upst ream bound778 defined by the dispersion model,
thereby reaching the southern part of the Ramsar site .
7.180. Wastewater treatment: it has already been explained in Section III that there are three
possible levels of effluent waste treatme nt in pulp mills. The European Union BREF
document (2001) on the pulp and paper industry stat es that tertiary treatment is necessary in some
779
cases . However, the Botnia proposal only provides for two levels of treatment.
336 7.181. The CIS refers to the AST process as a secondary treatment and claims that the mill
will do better than the IPPC-BAT (2001) guideline. It also maintains that effluent flows from the
Orion mill will compare favourably with pulp mills around the world 78. The CIS report states that
the mill will implement the IPPC-BAT recommendations for biological treatment, as it will use
state-of-the-art methods for treatment and dischar ge into the RiverUruguay, and that the impact
from marginal additional reduction in colour and nutr ients “is likely to be insignificant”. Tertiary
781
treatment was therefore not considered necessary .
7.182. Argentina absolutely contests this fi nding of the CIS. As confirmed by the IAEST’s
conclusions, and given the present situation of th e river in terms of contamination (regarding

780See the CIS, p. ES.ix. Anns., Vol. V, Ann. 6.
781The first CIS recommended (in Ann.D, p.ES-4) that the wastewater treatment facilities design for the mill
should include the provision for a tertiary treatment upgrade to meet potential future DINAMA or IFC requirements, or if
monitoring shows additional treatment would be needed to m eet current or future water quality standards. This
recommendation was not included in the final version of the CIS. - 190 -
phosphorus, for example) and DINAMA’s surface water quality requirements, it is unacceptable
for the proposed secondary treatment to be the fi nal treatment stage for mill effluent and for no
tertiary treatment to be put in place. The arguments of the CIS against the construction of a tertiary
treatment plant are quite simply unconvincing.
7.183. The BREF IPPC document confirms that, in some cases, tertiary treatment is
necessary, when the concentration of nutrients in the effluent has to be reduced because of the
sensitivity of the waters receiving the mill discharg es. The location of the Orion mill means that
discharges will take place into waters of this kind, and that tertiary treatment is therefore required.
337 7.184. The CIS is therefore wrong to conclude that the construction of a tertiary treatment
plant is not necessary in the case of the Orion mill . It is also wrong to conclude that tertiary
treatment is not needed to meet water quality sta ndards. The fact is that, given the present degree
of contamination in terms of to tal phosphorus content, which is f our times higher than the level
permitted by Uruguayan Decree253/79, the total p hosphorus in the RiverUruguay needs to be
782
reduced and any further discharges of total phosphorus must absolutely be prevented .
7.185. It appears that Botnia is “considering” the option of treating the municipal wastewater
from Fray Bentos at its own treatment plant, whic h would effectively eliminate, according to the
CIS, a significant source of biological oxygen demand (BOD), phosphorus and bacteria for the
beach area of Arroyo Fray Bentos, thereby improving the overall quality of the resource 783. The
CIS describes this possibility as a “significant bene fit” that should be considered further by
DINAMA.
7.186. However, while the treatment of wastewater from Fray Bentos by the Orion mill may
help to reduce the problem of excess phosphorus, tert iary treatment remains necessary to deal with
the significant additional volume of discharges associat ed with the mill itself, particularly in view
of its location. The Wheater report points out that secondary treatment using the activated sludge
reactor (ASR) system is not designed to remove nutrients, which requires tertiary treatment. It also
criticizes the CIS for indicating that “special atten tion has been made in this study regarding the
control and minimum discharge of nutrients” and describes this statement as misleading, as there
are no design specifications for the ASR or other details of how nutrient discharges will be
338
minimized. Elsewhere in the CIS, it is recognized that the nutrient control at the Orion mill will
not be amongst the best in the world, nor ar e the emission standards. The Wheater report
concludes that overall “the strategy for assessing a nd controlling nutrient impacts is not developed
to a stage which allows a rigorous impact assessment” 78.
7.187. A further problem is the unsuitable dimensions of the emergency basin. The best
785
available techniques (BAT) specify the collection of almost all spillages and the use of
sufficiently large buffer tanks for storage of concentrated or hot liquids from the production
process 786. Botnia states that the mill design includes

“three 8-hour retention time basins (equa lization/emergency) that operate in a
semi-continuous manner, i.e. they are filled continuously, and then the effluent quality
in the basin is checked prior to discharge in to the AST. In the event that a spill has
occurred in the mill, the basin contents would have a high COD and would be
discharged into the AST in a manner that does not overload the system.”
7.188. However, equalization of the effluent s takes place in tw3 of the basins, which each
have an 8-hour capacity and operate alternately (2x25,000m ). The third basin, which also
corresponds to eight hours of normal output, will remain empty (25,000 m ). As the IAEST points
out, this extra basin cannot be seen as an em ergency basin in case of spillages or operating
problems, since it is in fact an operational fac ility and will be too small in the event of an
emergency 78. There ought to be a permanently empty emergency basin to cope with any major
spillage or significant changes in the effluent.
7.189. Proliferation of potentially toxic algae : because of the increased level of
339
eutrophication, especially in Ñandubaysal Bay, cyanobacteria and cyanotoxins will occur more
frequently. The risks associated with cyanobacter ia and cyanotoxins are discussed in detail in
Section 6.7.2 of the Latinoconsult report 78. The report examines the toxicity of microcystin and its
implications for humans and animals. It notes th at in temperate climates such as those of South
America, water bodies dominated by the genus Microcystis may exhibit a bloom season of six to
ten months 789.
7.190. The studies carried out on the gr ound by the IAEST confirmed the presence of a
species of cyanobacteria (Microcystis aeruginosa) which produces the toxin microcystin (primarily
a hepatotoxin), causing disease when ingested th rough water but posing a risk in the event of
recreational exposure. In conditions of high phosphorus concentration (see above), the hepatotoxic
strains produce greater amounts of toxin. Break down into the ambient water produces dissolved
toxins (essentially through the ag eing, death and lysis of the cells) and represents a danger to
health.
Management of solid waste
7.191. According to the CIS, the solid w aste produced by the mill operations will include
wood preparation waste; raw water treatment sl udge; green liquor dregs, grit and lime mud;
effluent treatment sludge; ash/sands; municipal solid waste; and hazardous waste 79.
340 7.192. The Argentine report to the GTAN critic ized the assessment of the treatment of solid
waste in the draft CIS and in the environmental impact studies provided by the company, because it
lacked precision on basic aspects su ch as the classification, quantification and destination of the
78At the Gunns mill, the emergency basin has a 25-hour capacit y, and the one at the Valdivia de Arauco mill has
enough capacity for 48 hours of operation.

generated waste, the location of the potential landf ills, and any other wast791anagement planning.
The report also noted the risk of possible toxic leaching into the river .
7.193. The final CIS states that the Orion mill will meet BAT standards and that no
cumulative impacts are expected from the manage ment and disposal of hazardous waste. The
report adds that the project proposes to construc t an on-site landfill for disposal of non-ha792dous
solid waste, and that the landfill design is consistent with state-of-the-art practice . Collection
systems will divert leachate to the effluent treatment plants 79. The CIS indicates that the Botnia
landfill has a design capacity of 19years and notes th at there is sufficient space at the site to
expand the landfill if necessary. The only potential organic waste is the sludge from Botnia’s river
water treatment system, and the volume of this is relatively small compared to the amount of
inorganic waste going to the industrial landfill. La ndfill gas venting systems can be installed to
allow decomposition gases to vent to the atmo sphere, or these gases could be collected for
combustion. A groundwater monitoring system will be installed.
7.194. The final CIS also points out that hazardous waste will be produced. Botnia estimates
that between 100 and 150tonnes of hazardous materials will be generated by the mill each year.
These will include small quantities of used oils, solvents, detergents, laboratory wastes, etc. 794
341 Tourism
7.195. The CIS recognizes that tourism is well established in and around the area where it
has unilaterally been decided to locate the Orion mill, and notes that Gualeguaychú, in Argentina,
is also an important centre of tourist activity , famous for its beaches and its annual carnival
795
(described in SectionII above) . However, Argentina must point out that the CIS draws no
conclusions from its findings and, in its analysis , totally underestimates the environmental impacts
of the pulp mill on tourism in the region.
7.196. The Argentine report to the GTAN of February 2006 emphasized that the operation of
the mill would have a negative impact on the provin ce of Entre Ríos, especially affecting tourism,
the values of properties, public health and the ecology. It referred in particular to the beach resort
of Ñandubaysal, from which a giant smoke-emitt ing chimney would be seen as a backdrop
(whereas this would not be visible from the Uruguayan resort of Las Cañas).
7.197. Water quality: with regard to the beach area of Ñandubaysal (Water Receptor11 in
the water quality study), the CIS recognizes that “on rare occasions” the flow of the river may
reverse direction and move trace levels of wastewater across the RiverUruguay towards
Ñandubaysal; however, it states that a dilution of 1: 700 is sufficient to reduce the concentration of
wastewater to non-measurable levels, and that th e predicted contribution from the mill is not
considered problematic for drinking water or protection of human health or aquatic life 796.
791See the Argentine report to the GTAN, p. 3. Anns., Vol. IV, Ann. 1.
792See the CIS, p. 4.70. Anns., Vol. V, Ann. 6.

796See the CIS, p. 4.57. Anns., Vol. V, Ann. 6. - 193 -
7.198. Argentina has already several times had occasion to criticize the systematic
342
underestimating by the CIS of the frequency of reverse flow. This underestimation has significant
implications for assessing the risk of wastewater contamination around Ñandubaysal, which may
also therefore be much greater than is recognized by the CIS.
7.199. Air quality and odour: the conclusion of the final version of the CIS is based on the
results of the air quality analysis797d states that there will be no significant impact on tourism from
odour, cumulative or otherwise . The report maintains that visitors to the Ñandubaysal beach
resort in Gualeguaychú will not experience air quality, odour or water pollution impacts as a result
798
of the pulp mill . Odour, which is the main air quality parameter of concern with regard to
tourism, will not be detectable under normal c onditions, according to the CIS, although it may be
detected under upset conditions at Fray Bentos a nd the international bridge. Likewise, it will not
be detectable in the tourism areas of Las Ca ñas or Ñandubaysal under normal conditions, but only
during upset conditions and at times of poor air disp ersion: “the odour effect level is predicted to
be above the detection threshold for a person with a sensitive sense of smell” 79. The CIS thus
states that, during an upset, someone at the beach resorts may detect an odour similar to those
experienced in daily life (such as garbage or a sewer), and that this occurrence is most likely during
pre-dawn when air dispersion is poor. Hence the CIS plays down the scale of the impact in terms
of odour, on the basis of statements that are vague, unfounded and subjective.
7.200. Visual nuisance: Botnia has denied that there will be any visual nuisance, but on the
343
contrary this will be significant at several places on th e Argentine side that are used for recreation.
The nuisance lies in the fact that Botnia’s pulp mill will form the backdrop to a magnificent
beachside panorama, an element seen by tour ists as an undesirable addition to the natural
landscape.
7.201. As regards Argentina, the CIS points out that the Orion mill will be the most visible
industrial site from the Argentine shore, located 13 km across and upriver fro m the beach resort of
Ñandubaysal. The report then turns to case studies of mills in British Columbia, which are said to
co-exist with tourist activities without difficulty 800. Argentine wishes to emphasize that this is a
fallacious approach, since the beach areas of Br itish Columbia and Ñandubaysal are not at all
comparable. What is taking place in British Columb ia is industrial tourism, which is not linked to
sun and beach activities. It must also be borne in mind that tourism accounts for almost 20 per cent
of the volume of economic activity in Gualeguaychú.
Navigation
7.202. The transportation network will be aff ected by the construction and operation of the
Botnia mill 801. The two most important flows of traffi c will be wood and othe r supplies delivered
to the mills and pulp exported from the mills. In addition, there will be transport of personnel to
and from the mills, and transport of domestic and hazardous waste to appropriate landfills.

800
See the Berlin Declaration on Biological Diversity and Sustainable Tourism.
80See the CIS, p. ES.xxvi. Anns., Vol. V, Ann. 6. - 194 -
7.203. The main modes of transport will be tr uck, barge or ship for wood and other supplies,
and barge or ship for pulp. The increase in river traffic compared to 2004 “will not be significant
344 because the pulp export traffic will replace the cu rrent logs and wood chip volumes being exported
or moved in river transport” 802, according to the CIS. However, the CIS states that the Botnia
operation will result in an increase in barge round trips from 5.3 to 6.3 per day 803. It is therefore
clear from the figures quoted in the CIS that there will be an increase in traffic.
7.204. During construction, the environmen tal impacts will be greatest in the immediate
vicinity of the mill, and will include increases in road accidents, gas emissions from vehicles and
the need for road maintenance. Plans to manage these impacts are being drawn up by the company.
ENCE has clearly stated that one of the key fact ors in its decision to withdraw from Fray Bentos
was the volume of road transport needed for the tw804rojects. It quoted the figure of 400,000
trucks per year for the operating lifetime of the mill . That is more than 1,000 movements per
day, a clear indication of the consequences of th e presence of such mills for the environment.
ENCE did not refer to river transport, but the figures are comparable.
Objective reasons for doubting Botnia’s ability to meet the proposed standards
7.205. A number of factors seriously call in to question the ability of the operators of the
Orion mill to meet the standards laid down for the mill’s operation. These factors are as follows:
(1) the deterioration in the performance of sister pulp mills in Finland in the period 2004-2005;
(2) documents showing that damages and compensatory interest have had to be paid in Finland to a
number of groups affected by the mills, in particular fishermen;
345 (3) Botnia’s obvious reluctance to provide public access to information (as opposed to distributing
it proactively);
(4) the repeated and unexplained changes in the estimates of effluent (see above);
(5) the proposals for toxicity testing, including the present capacity restrictions in Uruguay.
7.206. In short, Argentina maintains that Uruguay has not demonstrated that the Orion mill
would meet the standards required by the authorization that was granted, moreover in breach of the
1975 Statute.
Section VI
Conclusions
7.207. This chapter has dealt with the con sequences for the RiverUruguay of the proposed
operation of the Orion mill for the next 40 years.
⎯ Section II confirmed that the particular features of the River Uruguay make it an environment
that is intrinsically unsuitable for discharg es of the planned kind and scale, and that the
environmental quality and condition of this watercourse and its surr oundings are generally

satisfactory. This Section also showed that there already exist, in some respects, environmental
problems which the operation of the pulp mill would be likely to make seriously worse (such as
the presence of high levels of phosphorus in the waters in the immediate vicinity of the mill, on
the Argentine side).
⎯ SectionIII described the operation of the Ori on mill, indicating the environmental effects
346 which projects of this type are likely to ha ve, as well as the environmental risks that are
intrinsically associated with them. On the basis of these factors, it is quite impossible to state,
as Uruguay does in its position, that the Orion mill is not liable to affect the quality of the
waters of the River Uruguay (cf. Art. 7 of the 1975 Statute).
⎯ SectionIV explained in more detail the pl anned operating mode for the Orion mill and the
types of emissions it would produce. This Section also clearly established that the Orion mill is
liable to affect the quality of the waters of th e RiverUruguay. That is a characteristic which
entails a clear obligation for Uruguay to take all necessary measures to prove that the mill will
cause no damage to the aquatic environment or no pollution that constitutes a breach of the
1975 Statute.
⎯ SectionV further confirmed that the Orion mi ll would be intrinsically harmful to the
environment and that its operation will have dir ect and immediate effects in terms of air and
water quality, noise pollution, visual and genera l nuisance and risks to human and animal
health, for example by encouraging the appearan ce and spread of potentially toxic algae. The
specific impacts of the project on the tourism sector were also identified in this section.
⎯ Section VI thus definitively establishes that Ur uguay has authorized a facility which is “liable
to affect . . . the quality [of the waters of the River Uruguay]”, and that this authorization was
issued without Uruguay being able to demonstrat e that it had taken all necessary measures to
protect and preserve the aquatic environment of the River Uruguay and to prevent its pollution.
7.208 The general conclusion of the Wheater report is that the CIS does not provide an
347
adequate technical basis to satisfy concerns for the environmental impact of the proposed pulp mill.
It summarizes the deficiencies and the skewed approaches of the CIS as follows:
(a) water quality criteria for impact assessment based on dilution are inappropriate;
(b) uncertainty concerning environmental impacts is not recognized, nor the fact that detrimental
effects on aquatic life have been observed following secondary treatment of effluents. Nutrient
levels are a particular concern;
(c) the lack of consideration of sediment dynamics or sediment chemistry of the river/estuary
environments is a major omission;
(d) the effects of flow reversal are under-represen ted, and the uncertainty associated with short
records is not accounted for. No assessment is made of the impacts of climate variability or
climate change;
(e) the water quality analysis of effluent discharg es requires additional work; in particular, the
far-field hydrodynamic modelling requires valida tion with appropriate observational data and
appropriate treatment of uncertainty is required;
(f) the hydrological impact of the proposed plantations is not analysed; conclusions are based on
assertions that are inconsistent or erroneous;
(g) risks of accidental pollution have not been fully addressed. - 196 -
7.209. To summarize, Uruguay has shown itself unable to take full or satisfactory account of
805
348 all the impacts of the construction and operation of the Orion pulp mill on the environment . In
particular, Uruguay has failed to assess properly the capacity of this Section of the River Uruguay
to receive and cope with the proposed discharges, or with the risks associated with the operation of
the mill, over such a long period of time.
80See the Executive Summary of the Latinoconsult report, para .3, and Sec.1, p.13, where the approach of the
CIS to the potential environmental impacts of the Orion mill is described as “completely deterministic”. Anns., Vol. V,
Ann. 3. - 197 -
C HAPTER VIII
R EMEDIES SOUGHT BY A RGENTINA
351 8.1. It is apparent from the preceding chapters of this Memorial, in particular ChaptersIV
andV, that Uruguay is, by its acts and omissions , the source of several internationally wrongful
806
acts which entail its international responsibility , and is unable to invoke any grounds to excuse
their wrongfulness. It is therefore for the Court to establish its violations of the 1975 Statute
(Sect. I) and draw the necessary conclusions, in part icular to find that Uruguay has an obligation to
cease those breaches and resume performance of the provisions which have been breached
(Sect.II), to make reparation for the injury caused by those breaches by re-establishing the
situation that existed before the breaches were committed and, where that proves impossible, to
compensate for the damage caused thereby (Sect.III ), and to provide appropriate assurances and
guarantees of non-repetition of its wrongful conduct (Sect. IV).
Section I
Establishment by the Court of the internationally
wrongful acts committed by Uruguay
8.2. Having regard to the nature of the cas e, Argentina is not requesting the Court to
determine at this stage the amount of compensa tion due to it from Uruguay in reparation for the
807 808
injury suffered . Nor, with one exception is Argentina asking the Court to make, at least
exclusively, a declaratory judgment on its rights ⎯ although it would unque stionably be legally
possible for it to do so809⎯ because such a judgment would not fully compensate for the damage
caused to Argentina by Uruguay’s internationally wrongful conduct ⎯ conduct which is having,
and will continue to have, very specific consequences which require more than simple satisfaction.
352 8.3. Nonetheless, initially establishing the ex istence and substance of the breaches of the
1975 Statute would appear crucial for the Court to be able to give a ruling on the actual content of
the resulting responsibility of the respondent State. Indeed, it goes without saying that the
distinguished Court would not be in a position to give a ruling on the other submissions of
Argentina (cessation of breaches, principle of reparation and decision on the terms thereof, and
guarantees and assurances of non-repetition) if it had not first established the various breaches by
Uruguay of the obligations incumbent on that State under the Statute.
8.4. Those breaches were the subject of detaile d examination in ChaptersIV andV of this
Memorial and are recalled here. They are:
⎯ failure to comply with the mechanism for prio r notification and consultation provided for in
Chapter II of the 1975 Statute;
80Cf Arts. 1 and 2 of the Articles of the Inttional Law Commission on Responsibility of States for
Internationally Wrongful Acts, annexe d to resolution 56/83 of the GenAssembly of the United Nations of
12 Dec. 2001 (hereinafter “the ILC Articles”).
807
See para. 9.1 below.
808
See para. 0.17 above.
80Northern Cameroons (Cameroon v. United Kingdom), Preliminary Objections, Judgment, I.C.J. Reports 1963,
pp. 32-33: “That the Court may, in an appropriate case, make a declaratory judgment is indisputable.” - 198 -
⎯ breach of the obligation to carry out a full and objective study of the transboundary impact of
the Orion mill on the environment of the River Uruguay and the areas affected by it;
⎯ breach of the obligation to take all measures ne cessary for the optimum and rational utilization
of the River Uruguay;
⎯ breach of the obligation not to significantly impair the régime of the river or the quality of its
waters;
⎯ breach of the obligation to take all measures necessary to protect and preserve the aquatic
environment and prevent pollution; and
⎯ breach of the obligation to protect biodiversity and fishery resources.
8.5. These internationally wrongful acts of varying character must give rise to varied
consequences. Those consequences are the subject of the three sections which follow.
353 8.6. However, in one particular respect, declarations by the Court establishing the breaches
committed by Uruguay will in themselves be “appropriate satisfaction” 81. As Argentina has noted
811
above , on 21September2006 the Spanish company EN CE announced that it had reversed its
decision to locate the CMB mill at the site initially planned on the outskirts of Fray Bentos. At the
same time, its managers stated their intention to construct a similar mill elsewhere in Uruguay, but
did not indicate the exact location. This uncer tainty places Argentina in a position where it is
impossible for it to determine precisely the conseque nces of that decision. Argentina is therefore
forced to reserve all its rights in that regard.
8.7. The fact nonetheless remains that the decision to suspend the construction of the CMB
mill and to relocate it has no impact on the br eaches committed by Uruguay of the obligations
incumbent on it pursuant to Articles 7 to 11 of the 1975 Statute:
⎯ in breach of Article7, Uruguay gave ENCE authorization to construct the mill without
notifying CARU of the matter;
⎯ in breach of Article 8, Uruguay failed to provi de CARU with full information which would
have enabled Argentina to respond in connecti on with the plan with full knowledge of the
facts;
⎯ consequently, Uruguay did not allow Articles 8 to 12 of the 1975 Statute to be applied and, in
particular, it brought to a standstill any possi bility of reaching agreement as required in
Article 12.
8.8. There is unquestionably a dispute “concerning the interpretation [and] application of
the... Statute” within the meaning of Article60 of the Statute, which the Court has a duty to
resolve by establishing that Uruguay has committed serious breaches of the substantive provisions
referred to above. Argentina is all the more c oncerned that the Court should rule on this matter
810
See Corfu Channel (United Kingdom v. Albania), Merits, Judgment, I.C.J. Reports 1949 , p.35; see also the
operative part of the Judgment, p. 36. See also for example: International Tri bunal for the Law of the Sea, Judgment of
1 July 1999, M/V Saiga (No.2), Reports 1999 , Vol. 3, p.67, para.176the Decision of 30April 1990, Rainbow
Warrior (New Zealand/France), United Nations, Reports of International Arbitral Awards (RIAA), Vol. XX, pp. 272-273.
81See para. 0.5 above. - 199 -
because, in Argentina’s view, the very fate of the 19 75 Statute is at stake; Argentina is anxious to
354
preserve the integrity of that Statute and ensure its ef812tive application in the future, so as to
preserve its object and purpose and the “fraternal spirit” in which it was entered into.
Section II
Cessation of breaches and resumption of compliance with the
obligations laid down in the 1975 Statute
8.9. For the same reasons, it is essential th at the Court should order the cessation of the
breaches of the Statute attributable to Uruguay and the resumption of compliance with all the
obligations it lays down.
8.10. In that respect, an initial distinction must be drawn between continuing breaches of the
obligations laid down by the 1975 Statute and breach es of an immediate nature or which must be
recognized as having ceased at the date of drafting this Memorial ⎯ even though their effects are
still felt (and will continue to be so).
8.11. In the present case, not all the breaches of the obligations laid down by the
1975 Statute which are attributable to Uruguay have a continuing character, in the sense that some
of them were interna813nally wrongful acts once a nd for all when they occurred, even if their
effects still remain . This is particularly the case, for exam ple, with the lack of prior notification
of CARU, and with the authorization given by Uruguay to the ENCE and Botnia companies to
construct the mills at issue (and the associated facilities), regardless of the provisions of
Articles 7 et seq. of the Statute.
8.12. In those cases, wrongful acts which con tinue to have harmful effects for Argentina
occurred at the time when the decisions not to notify CARU of the mill projects, to authorize
construction, and not to require Botnia to suspe nd works were taken by Uruguay, but they were
355 wrongful acts of an immediate nature. Nonetheless, their effects continue to be felt (because of the
wrongful construction of the Orion mill and its probable commissioning in the relatively near
future814). Those decisions produced their full effects immediately, and it would not be reasonable
for the Court merely to “annul” them for failure to comply with the procedural obligations laid
down in the Statute and require Uruguay to “termina te” the lack of notification to CARU and the
authorization to proceed with construction.
8.13. Argentina also wishes to state expressly that it is not seeking an order from the Court to
the effect that Uruguay must, now, discharge the obligations incumbent on it under Articles 7 to 11
of the 1975 Statute:
81See the Preamble to the 1975 Statute.
813
See Art. 14 (1) of the ILC Articles (“Extension in time of the breach of an international obligation”).
81See para. 0.16 above. - 200 -
⎯ on the one hand, resumption of the procedure c ould only be formal in nature; by presenting
Argentina with a fait accompli regardless of th e provisions in question, Uruguay committed a
series of wrongful acts which are now completed 81;
⎯ on the other hand, and more importantly, by pr oviding for intervention by the International
816
Court of Justice (whose “judgment is final and without appeal” ) in the event that “the Parties
fail to reach agreement”, the dr afters of the 1975 Statute intended to avoid the danger of the
procedure for negotiations between the parti es not reaching an outcome, and it would be
fundamentally contrary to the spirit of Article 12 to require the procedure to resume after the
Court has given a ruling in a judgment constituting res judicata, even though the legal basis for
the jurisdiction of the Court in the present cas e is Article 60 alone, since Uruguay’s failure to
notify its plans to CARU brought the applica tion of ChapterII as a whole to a complete
standstill, including Article 12.
356 8.14. As regards the breaches of the “materia l” obligations incumbent on Uruguay pursuant
to the 1975 Statute, most of them have a continuing character and one of the most important
consequences of the Court’s findings in their regard will be to require the respondent State to cease
breaching those obligations and to resume performan ce of them. For example, the construction of
the Orion mill constitutes (and its future comm issioning would constitute) a continuing breach of
the obligation to take all appropriate measures to protect and preserve the aquatic environment and 817
to prevent pollution which the Parties entered into pursuant to Article41 (a) of the Statute ;
further, as is expressly stated in Article42, “[e] ach Party shall be liable to the other for damage
inflicted as a result of pollution caused by its own activities or by those carried out in its territory
by individuals or legal entities”.
8.15. Where these continuing breaches of treat y-based obligations or other comparable
internationally wrongful acts are concerned ⎯ such as the breach of the obligations not to cause
818
significant damage to Argentina or significantly impair the régime of the river and the quality of
its waters 819 or the “areas affected by it” 820⎯ the initial consequences of Uruguay’s responsibility
for these internationally wrongful acts are, on the one hand, to cease those acts and, on the other
hand, to resume performance of the obligations at issue.
8.16. Pursuant to Article 30 (a) of the ILC Articles:
“The State responsible for the internationally wrongful act is under an
obligation:
(a) To cease that act, if it is continuing.”
81See paras. 4 to 6 of the Commentary on Art. 14 of th e ILC Articles (International Law Commission, Report on
the work of its Fifty-third Session (23 April-1 June and 2 July-10 Aug. 2001), General Assembly Official Records ,
Fifty-sixth Session, Supplement No. 10 (A56/10), pp. 147-148).
81Art. 60 of the Statute of the Court.
81See paras. 5.27-5.29 above.
818
See Chap. V, Sec. III.
81Ibid.
82See Arts. 13 and 36 of the 1975 Statute. - 201 -
And, as the Commission states in the commentary on that Article: “Cessation of conduct in breach
357
of an inte821tional obligation is the first require ment in eliminating the consequences of wrongful
conduct.”
8.17. In the present case, the first consequence of a finding by the Court of breaches of the
1975 Statute must therefore be the cessation of breaches of a continuing character and the
resumption of full application of the Treaty as its corollary.
8.18. As Article 29 of the ILC Articles states: “the legal consequences of an internationally
wrongful act . . . do not affect the continued duty of the responsible State to perform the obligation
breached”. In the present case, resumption of perform ance has a special significance: if it did not
occur, then Uruguay, by violating the 1975 Statute, would achieve its termination de facto, whereas
Argentina, rather than accepting such a con sequence, is seeking to ensure, as is its right 822, that
Uruguay fully complies with the obligations incumbent on it under the 1975 Statute.
8.19. Therefore, following a judgment by the Court, Uruguay will have to cease the
continuing breaches of the obligations under, inter alia, Articles1 and27 (on the optimum and
rational utilization of the waters of the river), Articles35 and36 (obligation to co-ordinate the
necessary measures to avoid any change in the ecological balance in the river and the areas affected
by it) and Article 41 (a) (which lays down obligations to take all necessary measures to preserve
the aquatic environment and prevent its pollution) , and of the general obligations ensuing from
358 those provisions not to cause significant damage to Argentina or significantly impair the régime of
the river and the quality of its waters.
Section III
Reparation by Uruguay for the injury caused by
its internationally wrongful acts
8.20. In addition to the obligations referre d to above resulting from Uruguay’s international
responsibility, Uruguay is under an obligation to ma ke full reparation for the damage sustained by
Argentina as a result of the breaches of its intern ational obligations pursuant to the 1975 Statute
which are attributable to it.
8.21. In accordance with the celebrated dictum of the Permanent Court of International
Justice in its Judgment of 13 September 1928 in the case concerning the Factory at Chorzów:
“[t]he essential principle contained in the actual notion of an illegal act ⎯ a principle
which seems to be established by interna tional practice and in particular by the
decisions of arbitral tribunals ⎯ is that reparation must, as far as possible, wipe out all
821
See para. 4 of the ILC Articles (A/56/10), op. cit., p. 217.
82See Art.60(1) of the Vienna Convention on the Law of Treaties of 23 May 1969, the customary nature of
which is not in doubt (see Legal Consequences for States of the Conti nued Presence of South Africa in Namibia (South
West Africa) notwithstanding Security Council Resoluti on 276 (1970), Advisory Opinion, I.C.J. Report, p. 47;
Gabčíkovo-Nagymaros Project (Hungary/Slovakia), op. cit., p. 68, para. 114; or para. 3 of the Commentary on Art. 29 of
the ILC Articles (A/56/10), op. cit., p. 215. - 202 -
the consequences of the illegal act and re-est ablish the situation 823ch would, in all
probability, have existed if that act had not been committed” .
The adequate form of the repa ration depends upon “the concre te circumstances surrounding each
case and the precise nature and scope of the injury , since the question has to be examined from the
viewpoint of what is the ‘reparation in an adequate form’ that corresponds to the injury” 824. It may
825
359 take the form of restitution, compensation or satisfaction , it being understood that the various
means of reparation may be combined, the essence being to achieve full reparation 826.
8.22. Pursuant to Article 35 of the ILC Articles:
“A State responsible for an internatio nally wrongful act is under an obligation
to make restitution, that is, to re-estab lish the situation which existed before the
wrongful act was committed, provided and to the extent that restitution:
(a) Is not materially impossible;
(b)Does not involve a burden out of all proportion to the benefit deriving from
restitution instead of compensation.”
It follows that the State responsible has an oblig ation to take all necessary measures to re-establish
the situation which existed before its internationally wrongful act or acts was or were committed.
8.23. As was established in Chapter IV of this Memorial, one of the internationally wrongful
acts for which Uruguay is responsible consists in authorizing the construction of pulp mills and
associated facilities in breach of several obligations incumbent on it under the 1975 Statute and the
rules of international law referred to therein. A ppropriate restitution therefore consists, firstly, in
the annulment of those authorizations. The annulment of administrative acts taken in breach of
international law has in827d been recognized as an appropriate means of restitution, since it wipes
out the wrongful act . That request applies both to the CMB and the Orion mills since, as far as
Argentina is aware, the authorization granted to ENCE to construct the CMB mill has not been
officially withdrawn, despite ENCE’s decision to relocate the mill.
8.24. As far as Orion is concerned, the br eaches of the obligations incumbent on Uruguay
360 under the Statute have resulted directly in a giga ntic paper mill and associated facilities being on
the point of completion on the left bank of the River Uruguay and due to be commissioned before
the Court delivers its judgment. The annulment of the authorization to construct this mill and the
port associated with it, and of the authorizations to begin operations at the port and extract and use
a significant volume of water annually from the River Uruguay, may indeed wipe out the wrongful
acts in themselves, but is definitely not sufficient to wipe out all the consequences of those acts.

82See Art. 35 of the ILC Articles, para. 5 of the Commentary (ibid., p. 240). - 203 -
Only the dismantling of the mill and its associ ated facilities or, where appropriate, their
reassignment to other uses compatible with the provisions of the 1975 Statute can re-establish the
statu quo ante.
8.25. In no way is this means of restitution disproportionate as compared to compensation 828.
Mere payment of compensation is not capable of wiping o829all the damage which the mills at
issue, which have an estimated lifetime of at least 40 years , will continue to cause in the future to
the régime of the River Uruguay, the quality of its waters and the areas affected by it ⎯ damage
which it is impossible to assess precisely at present.
8.26. Moreover, in its Order of 13July 2006, the Court warned Uruguay against the
consequences of non-suspension of the works when it stated:
“Whereas in proceeding with the auth orization and construction of the mills,
Uruguay necessarily bears all risks relating to any finding on the merits that the Court
might later make; whereas the Court points out that their construction at the current
site cannot be deemed to create a fait accompli because, as the Court has had occasion
to emphasize, ‘if it is established that the construction of works involves an
infringement of a legal right, the possi bility cannot and should not be excluded a
priori of a judicial finding that such works must not be continued or must be modified
or dismantled’ ( Passage through the Great Belt (Finland v. Denmark), Provisional
Measures, Order of 29 July 1991, I.C.J. Reports 1991, p. 19, para. 31).” 830
8.27. Uruguay itself has also expressed its awar eness of the risk of having to dismantle the
361
mills in the event that it is held responsible fo r breaches of its obligations under the 1975 Statute
and the rules of international law referred to ther ein. It was stated at the hearing on 8June 2006
that:
“it should be for Uruguay to decide whether to risk proceeding with the construction
of the plants in light of Argentina’s claim. If the Court, at the conclusion of the merits
phase, were to order the plants closed, or dismantled, Uruguay would have to live with
that result.”831
832
The Court noted that statement . In consequence, Uruguay could not in any event contend that
full restitution is disproportionate.
8.28. To the extent that restitution cannot “w ipe out all the consequences of the wrongful act
and re-establish the situation which would, in all pr obability, have existed if that act had not been
committed”, Uruguay is under an obligation to co mpensate Argentina for material damage
suffered. The compensation must cover any financially assessable damage, including loss of
profits in so far as it is established 833.

83See Art. 36 of the ILC Articles. - 204 -
8.29. The damage actually sustained by Arge ntina as a result of the unilateral and wrongful
authorizations to construct the Orion mill and th e associated facilities, their construction and their
834
future commissioning exceeds what can be re-established by annulling the authorizations and
dismantling the mill. Following the granting of th e authorizations and since construction of the
mills commenced, Argentina has had to deal with major economic and financial losses and damage
which it has suffered directly and through its nationals. That damage includes, but is not limited to:
362 ⎯ the financial losses sustained by tourism operato rs in the Gualeguay835 region, particularly
because of the significant drop in tourist-related activities ;
⎯ damage resulting from the decline in property values, rental prices and economic activity in
general in that area affected by the river experiencing the consequences of the construction and
possible future commissioning of the mills 83;
⎯ significant additional expenditure and losses in the agricultural, apiculture and fisheries sectors
837
which could occur in the event of the mills becoming operational in the future .
8.30. All this damage is the direct result of the authorization and construction (to which we
may add the commissioning, very probably before this case reaches a conclusion) of the Orion mill
and the changes made to the ecosystem of the Ri ver Uruguay and the areas affected by it. Because
of the installation and operation of the Orion i ndustrial complex and the threat it poses to the
ecosystem of the river and the areas affected by it 838, the Gualeguaychú region is likely to see a
839
significant decline in its rapidly developing ecotourism sector , for which the region is a
well-known base. The loss of profits for future ye ars is considerable even though at the time of
writing it is still very difficult to place a figure on the injury in this respect.
8.31. At this stage in the proceedings, Arge ntina finds itself in a situation where it is
impossible to assess all the damage sustained, whet her by reason of the construction proceeding or
the future operation of the mill. Consequently, at this stage, in keeping with customary practice in
situations of this kind, Argentina is seeking fro m the Court only a finding that Uruguay is required
to make compensation for the damage sustained as a result of the internationally wrongful acts
363 which the Court has found to exist 840, while reserving the assessment and determination of the
841
amount of injury suffered for a subsequent stage of the proceedings .
834

extract and use water from the River Uruguay for industria l purposes granted to Botnia on 12 Sept. 2006. Anns.,

Section IV
Argentina is entitled to appropriate guarantees and assurances of
non-repetition of Uruguay’s wrongful conduct
8.32. Pursuant to Article 30 (b) of the ILC Articles:
“The State responsible for the internationally wrongful act is under an
obligation:
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
(b) To offer appropriate assurances and guara ntees of non-repetition, if circumstances
so require.”
That is the situation in the present case.
8.33. The ILC commentary on that provision notes that the guarantees and assurances of
non-repetition are presented as:
“an aspect of the continuation and repair of the legal relationship affected by the
breach. Where assurances and guarantees of non-repetition are sought by an injured
State, the question is essentially the reinfo rcement of a continuing legal relationship
and the focus is on the future, not the past.”842
8.34. Having regard to the facts and circumstances at the heart of the dispute between
Argentina and Uruguay, Uruguay is certainly re quired to give assurances and guarantees of
364 non-repetition. The repeated and deliberate breaches of the 1975 Statute, and in particular of the
procedure provided for in Articles 7 et seq. thereof, illustrate the extent to which those guarantees
are appropriate in the present case. Mere reparation for the damage suffered is not sufficient to
restore Argentina’s confidence in future complian ce by Uruguay with the Statute, which, as noted
in Chapter III of this Memorial, is the framework for continued and extensive co-operation between
the Parties.
8.35. It is hardly necessary to draw the Court’ s attention once again to the fact that, despite
the most vigorous protests by Argentina and its attempts to find an amicable solution, complying
with both the letter and the spirit of the 1975 Statut e, to the dispute arising from the authorization
to construct the CMB mill that was unilatera lly granted by the Respondent, Uruguay continued
openly to breach its obligations when it authori zed the construction of the second mill, Orion, and
then the port for Orion’s exclusive use. Those acts have profoundly shaken Argentina’s confidence
in Uruguay’s commitment to the 197 5 Statute, the importance it attaches to it, and its intention to
comply with it in the future.
8.36. Events subsequent to the filing of the Application but inherently connected with it have
also contributed to undermining that confidence further. Indeed, Uruguay once again released
itself from the procedure laid down by Articles 7 to12 when on 24August2006, without CARU
having been notified in advance, the port associ ated with the Orion mill, which had been
842
Para. 11 of the Commentary, ILC Articles, (A/56/10)), op. cit., p. 236. - 206 -
unilaterally authorized, was brought into operation 843, and when on 12September2006 an
3
authorization to extract 60millionm water per annum (until 2011) w as granted to Botnia. This
manner of proceeding clearly shows that Uruguay in no way intends to be subject to the
1975Statute where the construction and commissioning of the Orion mill are concerned.
Furthermore, the plan for another pulp mill in Ur uguay, this time on the Río Negro, a tributary of
365 the River Uruguay, which would be constructed and operated by Stora Enso, a Finno-Swedish
company, is currently being studied; this is a matter that can only be a source of concern to
844
Argentina, which has very little information on the plan .
8.37. In those circumstances, in order to repa ir the legal relationship between the two Parties
on the basis of the fraternal spirit, co-operati on and mutual confidence which have traditionally
been its distinguishing features, Argentina asks Uruguay to specifically commit itself to comply
scrupulously in future with the obligations ar ising from the 1975 Statute, in particular the
procedure provided for in Articles7 et seq. ; otherwise that Statute will in the long term be
devoided of its object and purpose, no doubt irremediably.
8.38. Argentina is aware of the fact that the Agent of Uruguay has already stated, at the
hearing of 8June 2006, the “intention [of Uruguay] to comply in full with the 1975 Statute of the
River Uruguay and its application” 845. Recent events regarding the authorization for
commissioning of a port associated with the Ori on mill, the authorization to extract significant
quantities of water from the river or the Stora En so mill plan nevertheless demonstrate that
Argentina has good reason to be sceptical of the seriousness of the commitment thus expressed.
8.39. Therefore, Argentina is of the view that a formal declaration made by a competent
authority of Uruguay, a declaration which is more precise than the one given by that country’s
Agent at the hearings on the request for the i ndication of provisional measures, whereby Uruguay
would undertake to comply in future with the provisions of Articles7 et seq. of the 1975 Statute
and of which the Court would take formal note in the operative part (and not merely in the grounds)
of its judgment would be one possible means of giving such assurances and guarantees of
non-repetition. That undertaking, whic h would therefore have the force of res judicata, could be
366 supplemented by the establishment by Uruguay, in conjunction with Argentina, of a fund to support
the preservation and improvement of the environment of the River Uruguay and the areas affected
by it. Moreover, joint management of that fund by both Parties would constitute a guarantee
capable of restoring Argentina’s confidence in Uruguay’s adherence to the 1975 Statute.
8.40. Argentina’s submissions which follow summarize the conclusions to be drawn from
the considerations set out in this chapter with regard to:
(i)the establishment by the Court of the internationally wrongful acts attributable to
Uruguay;
(ii) the cessation of the continuing breaches a nd the resumption by Uruguay of its obligations
under the 1975 Statute;

from Uruguay. - 208 -
S UBMISSIONS
369 9.1. For all the reasons described in this Memorial, the Argentine Republic requests the
International Court of Justice:
1. to find that by unilaterally authorizing th e construction of the CMB and Orion pulp mills and
the facilities associated with the latter on the left bank of the River Uruguay, in breach of the
obligations resulting from the Statute of 26Fe bruary1975, the Eastern Republic of Uruguay
has committed the internationally wrongful acts set out in Chapters IV and V of this Memorial,
which entail its international responsibility;
2. to adjudge and declare that, as a result, the Eastern Republic of Uruguay must:
(i) cease immediately the internationally wrongful acts referred to above;
(ii) resume strict compliance with its obligations under the Statute of the River Uruguay of
1975;
(iii)re-establish on the ground and in legal terms the situation that existed before the
internationally wrongful acts referred to above were committed;
(iv)pay compensation to the Argentin e Republic for the damage caused by these
internationally wrongful acts that would not be remedied by that situation being restored,
of an amount to be determined by the Court at a subsequent stage of these proceedings;
(v) provide adequate guarantees that it will refrain in future from preventing the Statute of the
River Uruguay of 1975 from being applied, in particular the consultation procedure
established by Chapter II of that Treaty.
9.2. The Argentine Republic reserves the right to supplement or amend these submissions
370 should the need arise, in the light of the developm ent of the situation. This would in particular
apply if Uruguay were to aggravate the dispute 84, for example if the Orion mill were to be
commissioned before the end of these proceedings.
