At Coastal GasLink, environmental protection is paramount, which is why we employ the highest standards possible to protect waterways during construction.
Starting the right way
Coastal GasLink initiated environmental consultation long before our construction shovels broke ground in 2019. We’ve conducted environmental field programs since 2012, consisting of up to 72 fisheries and aquatics crews, including fisheries biologists, as well as First Nations participants, who gathered site-specific information on fish and fish habitat.
In 2013, we spent more than 100,000 hours conducting environmental and engineering studies and assessments, including geotechnical investigation on potential trenchless crossings, geophysical surveys, flow measurements and assessments on water crossings.
Water quality monitoring is key to protecting aquatic habitats during construction, including during the installation of temporary bridges needed in various locations along the route for our crews to safely access the right-of-way or when safely installing pipe deep beneath riverbeds.
Water quality monitoring, for example, was done during recent installation of a temporary bridge over the Stuart River, an important waterway that contains numerous species of fish including White Sturgeon.
Coastal GasLink Environmental Consultant
Our Environment team monitors water quality as outlined in the Project’s Water Quality Monitoring Plan using equipment that measures the turbidity, pH level and dissolved oxygen concentration. Water quality monitoring is implemented at all fish bearing streams along the project to ensure Project mitigations are applied effectively and any potential effects are identified immediately and managed accordingly.
