Includes bibliographical references. "The construction of pipeline crossings can result in detrimental effects on ecosystem health and functioning in streams and rivers through alteration of stream and river channels, banks, and water and sediment quality. This document reviews impacts of pipeline crossing construction on watercourses and proposes a study design to assess the impacts of the Mackenzie Gas Project (MGP) on various streams and rivers along the Mackenzie River. The MGP Environmental Impact Assessment was examined to identify the approach taken by the MGP in assessing potential impacts of crossing construction and along with the “dominant” literature, was reviewed to identify key indicators of crossing construction impact (e.g., water quality, habitat, invertebrate and fish communities) and thresholds associated with these variables. Candidate crossing sites were selected for investigation in 2005/2006"--Report objectives, page 3. gccst Pipelines gccst Environmental impact assessment gccst Rivers Dubé, Monique,‏‎ 1967-‏ author.
