The Impact Assessment Agency of Canada is contemplating the following potential conditions in relation to the Lake Manitoba and Lake St. Martin Outlet Channels Project (the Designated Project) located in Manitoba for recommendation to the Minister of the Environment (the Minister) for inclusion in a Decision Statement issued under the Canadian Environmental Assessment Act, 2012. If the Minister decides that the carrying out of the Designated Project is unlikely to cause significant adverse environmental effects as defined under subsections 5(1) and 5(2), or if the Minister decides that the Designated Project is likely to cause significant adverse environmental effects and the Governor in Council decides such effects are justified in the circumstances, the Designated Project would be allowed to proceed, and any conditions established by the Minister under the Canadian Environmental Assessment Act, 2012 would become legally binding.

Pursuant to section 184 of the Impact Assessment Act, a Decision Statement issued by the Minister under subsection 54(1) of the Canadian Environmental Assessment Act, 2012 is deemed to be a Decision Statement issued under subsection 65(1) of the Impact Assessment Act, other than for the purposes of section 70.

8.7 The Proponent shall develop, prior to construction and in consultation with Indigenous groups and relevant authorities, a cultural heritage management plan to mitigate effects on tangible and intangible physical and cultural heritage caused by the construction and operation of the Project. The plan shall be implemented during all phases of the Project. As part of the plan, the Proponent shall:

8.7.1 identify and describe the tangible and intangible aspects of Indigenous cultural heritage and sites of significance within the Designated Project area, and local and regional assessment area identified in Figure 10 of the Environmental Assessment Report, including intangible aspects related to knowledge transmission, language and cultural continuity as articulated by Indigenous groups.

8.7.7 determine the frequency with which the plan will be reviewed.

8.8 The Proponent shall review, at a minimum once every five years the Lake Manitoba and Lake St. Martin Water Control Structures Operating Guidelines in consultation with Indigenous groups and relevant authorities to assess the need for updates to these guidelines to support Indigenous groups' current use activities and cultural practices within the local and regional assessment area identified in Figure 10 of the Environmental Assessment Report, taking into account the results of follow-up programs related to current use and cultural heritage pursuant to conditions 7.20, 7.21, 7.22, 8.9 and 8.10 and recommendations of the EAC pursuant to condition 7.2. The Proponent shall update the guidelines based on this review.

8.9 The Proponent shall develop, prior to construction and in consultation with Indigenous groups and relevant authorities, a follow-up program to verify the accuracy of the environmental assessment and to determine the effectiveness of all mitigation measures identified to mitigate effects to any structures, sites, or things of historical, archaeological, paleontological, or architectural significance or physical or cultural heritage resources. The Proponent shall implement the follow-up program during all phases of the Designated Project. As part of the implementation of the follow-up program, the Proponent shall:

8.9.1 monitor the known heritage sites identified in condition 8.1 and the areas within the local assessment area identified pursuant to condition 8.7.1 if the results of the follow-up program referred to in 3.19 indicate changes to water quantity or quality attributable to the Designated Project;

8.9.2 identify heritage resources that may be adversely impacted by the Designated Project in ways other than through changes to surface water quantity and quality, and monitor these heritage resources during construction and the first 10 years of operation; and

8.9.3 develop and implement additional mitigation measures if the results of the monitoring referred to in conditions 8.9.1 and 8.9.2 shows adverse effects to physical and cultural heritage attributable to the Designated Project.

8.10 The Proponent shall develop, prior to construction and in consultation with Indigenous groups and relevant authorities, a follow-up program to verify the accuracy of the environmental assessment and to determine the effectiveness of all mitigation measures for effects to any structures, sites, or things of historical, archaeological, paleontological, or architectural significance or physical or cultural heritage resources due to erosion along the Lake St. Martin Narrows and the islands within Lake St. Martin. The Proponent shall implement the follow-up program during all phases of the Designated Project. As part of the implementation of the follow-up program, the Proponent shall:

8.10.1 identify shoreline locations along the Lake St. Martin Narrows and islands within Lake St. Martin at risk for shoreline erosion;

8.10.2 identify cultural heritage resources of importance to Indigenous groups in these areas at risk for erosion;

8.10.3 monitor the locations identified in condition 8.10.1 and the resources identified in condition 8.10.2 for increased erosion attributable to the Designated Project, including through bathymetry. If the results of the surface water follow-up program referred to in 3.20 indicate changes to water quantity or quality attributable to the Designated Project, the Proponent shall develop and implement additional monitoring; and

8.10.4 develop and implement modified or additional mitigation measures to protect these resources if the results of the monitoring referred to in condition 8.10.3 shows adverse effects to physical and cultural heritage attributable to the Designated Project.
