Science review of the Tazi Twé Hydroelectric Project environmental impact statement

Context

The proposed Tazi Twé Hydroelectric Project, located in northern Saskatchewan, is subject to a federal environmental assessment under the Canadian Environmental Assessment Act (2012). On March 1, 2013, the Canadian Environmental Assessment Agency (CEAA) commenced the Project’s environmental assessment. The Proponents, Black Lake First Nation and Saskatchewan Power Corporation, submitted the Tazi Twé Hydroelectric Project’s Environmental Impact Statement (EIS) to CEAA on February 21, 2014. Fisheries and Oceans Canada (DFO) is a federal authority for the review of this project and must comment on the potential for the Project, as proposed, to result in significant adverse environmental effects.

DFO’s Fisheries Protection Program (FPP) requested advice from DFO Science on whether the baseline information in the EIS is adequate to support the Proponents’ conclusions about the Project. They requested that Science focus on the section of the Fond du Lac River to be impacted by the Project. They asked if the Proponents’ conclusions regarding potential impacts to resident Arctic Grayling population(s) due to flow reductions in the Fond du Lac River are supported. Science was also asked to identify deficiencies and approaches to address areas of deficiency in the EIS. The request was submitted to Science on September 12, 2014 with a response required by October 2, 2014.

This Science Response results from the Science Response Process of September 2014 to provide a Science review of the Tazi Twé Hydroelectric Project’s Environmental Impact Statement (EIS).
