Comprehensive Study Report

1. Introduction

The Department of Fisheries and Oceans (DFO) has prepared this comprehensive study report on the proposal to build a new hydroelectric facility at Grand-Mère submitted by Hydro-Québec, project proponent. The report fulfils DFO's obligation as a responsible authority under the Canadian Environmental Assessment Act (CEAA) to conduct an environmental impact assessment of the project in consultation with other federal authorities with appropriate expertise.

This document includes a brief description of the project and the environment in which it will take place, the results of the public consultations held by the proponent, a summary of the main environmental effects, the cumulative effects and the effects of malfunctions and accidents that may occur in connection with the project, the mitigation measures and associated follow-up, the determination of the significance of those effects, the approval conditions and a preliminary conclusion regarding the environmental acceptability of the project.

The documents mentioned below are also part of this comprehensive study report and have been used in preparing it. They provide more detailed information on the above-mentioned aspects along with the proponent's responses to questions raised during the screening analysis, which is part of the Quebec government's environmental assessment process, and additional elements required to meet the requirements of an environmental assessment under the CEAA.
