Conawapa Generating Station - Environmental Impact Statement

The 1300 MW Conawapa GS project is one of Manitoba Hydro's options for future hydroelectric generation. Detailed planning commenced in 1988 and continued until the project was deferred in 1992. Detailed planning recommenced in 2004 and continued until 2014 when the project was again deferred.

During both planning stages, NSC was responsible for the aquatic component of the Environmental Impact Assessment (EIA). NSC was also responsible for the resource use component of the more recent EIA process. The information generated from these studies, along with traditional knowledge provided by the First Nations, was to be used to prepare an Environmental Impact Statement for the proposed development and determine future monitoring programs.

NSC's role in the project:

• Conducted aquatic baseline studies and prepared the aquatic component of the initial environmental assessment and participated in initial scoping hearings from 1988-1992.
• Conducted a second round of aquatic environment baseline studies from 2004-2015 as part of a multidisciplinary EIA team.
• Incorporated traditional knowledge into environmental assessments and trained First Nations personnel.
• Coordinated logistics and managed First Nation participation for all terrestrial and aquatic field studies.
• Liaised with regulators and First Nation communities.
• Lead the development of aquatic mitigation and offsetting plans.
• Prepared Consolidated Technical Memoranda summarizing and archiving the assessment work carried out during the EIA.
