Executive Summary
The objectives of the Project were to undertake a surface-level assessment for the potential environmental effects of pipelines abandoned in-place along three previously abandoned segments of the NGTL PRML Pipeline, and to identify areas where further subsurface assessment could be performed to provide additional information pertaining to a pipeline abandoned in-place. The surface level assessment did not reveal any evidence of the potential environmental effects of abandoning a pipeline in-place. Areas where additional assessment may be considered were determined using the most recent pipeline abandonment research and applying it to the locations identified during the literature review and field assessment.
