5SSR staff led the development of the Fish and Fish Habitat Impacts Assessment Tool (FFHIAT), which standardizes assessments and reporting for pipeline and associated temporary vehicle crossing projects to be compliant with the Fisheries Act and Species at Risk Act. The tool was funded by the Canadian Energy Pipeline Association (CEPA), along with its partners the Canadian Gas Association (CGA) and the Canadian Association of Petroleum Producers (CAPP) and developed in collaboration with the Canadian Energy Regulator (CER) and Fisheries and Oceans Canada (DFO). The tool uses DFO’s Pathways of Effects (PoEs) to identify the applicable stressors, pathways, and effects for a given activity, and applies avoidance and mitigation measures to break or limit these pathways. A comprehensive literature review was completed to provide the science and evidence-based support for the operational guidance in the FFHIAT; this review was summarized in a science support document that underwent review by DFO’s Canadian Science Advisory Secretariat, a DFO scientific peer review and analysis process.
