PULP MILLS (JUDGMENT) 59 the plan, subject to it requesting the other party, through the Commission, to supplement as necessary the documentation it has provided. If the notified party raises no objections, the other party may carry out or authorize the work (Article 9). Otherwise, the former must notify the latter of those aspects of the work which may cause it damage and of the suggested changes (Article 11), thereby opening a further 180-day period of negotiation in which to reach an agreement (Article 12). 115. The obligation to notify is therefore an essential part of the process leading the parties to consult in order to assess the risks of the plan and to negotiate possible changes which may eliminate those risks or minimize their effects. 116. The Parties agree on the need for a full environmental impact assessment in order to assess any significant damage which might be caused by a plan. 117. Uruguay takes the view that such assessments were carried out in accordance with its legislation (Decree No. 435/994 of 21 September 1994, Environmental Impact Assessment Regulation), submitted to DINAMA for consideration and transmitted to Argentina on 7 November 2003 in the case of the CMB (ENCE) project and on 19 August 2005 for the Orion (Botnia) project. According to Uruguay, DINAMA asked the companies concerned for all the additional information that was required to supplement the original environmental impact assessments submitted to it, and only when it was satisfied did it propose to the Ministry of the Environment that the initial environmental authorizations requested should be issued, which they were to CMB on 9 October 2003 and to Botnia on 14 February 2005. Uruguay maintains that it was not required to transmit the environmental impact assessments to Argentina before issuing the initial environmental authorizations to the companies, these authorizations having been adopted on the basis of its legislation on the subject. 118. Argentina, for its part, first points out that the environmental impact assessments transmitted to it by Uruguay were incomplete, particularly in that they made no provision for alternative sites for the mills and failed to include any consultation of the affected populations. The Court will return later in the Judgment to the substantive conditions which must be met by environmental impact assessments (see paragraphs 203 to 219). Furthermore, in procedural terms, Argentina considers that the initial environmental authorizations should not have been granted to the companies before it had received the complete environmental impact assessments, and that it was unable to exercise its rights in this context under Articles 7 to 11 of the 1975 Statute. 119. The Court notes that the environmental impact assessments which are necessary to reach a decision on any plan that is liable to cause sig49
