Reasons for a Federal Assessment

On February 5, 2007, it was determined that an environmental assessment was required in relation to the project because Fisheries and Oceans Canada considered taking action in relation to section 32 of the Fisheries Act and to subsection 35(2) of the Fisheries Act.

Project Description (as posted in the Notice of Commencement)

Ontario Power Generation (OPG) is proposing to redevelop the Lower Mattagami hydroelectric complex, located approximately 70 km northeast of Kapuskasing. Little Long, Harmon and Kipling generating stations will be expanded with the addition of a turbine/generator and the Smoky Falls site will be redeveloped to accommodate a new generating station. With this development proposal, OPG wishes to provide increased overall generating capacity as well as promote more efficient operation and use of water through the complex.

Environmental Assessment Decision Statement

Final Decision

A decision was taken on April 26, 2010 and was that the authority may exercise any power or perform any duty or function with respect to the project because, after taking into consideration the comprehensive study report and taking into account the implementation of appropriate mitigation measures, the authority is of the opinion that the project is not likely to cause significant adverse environmental effects.

Follow-up Program

It was determined that a follow-up program to verify the accuracy of the environmental assessment and/or determine the effectiveness of any measures taken to mitigate the adverse environmental effects is required for this project.
