British Columbia has amended the conditions of its environmental assessment certificate for the Trans Mountain pipeline expansion and told the federal government it still has concerns about its response to potential marine oil spills.
The changes announced in late February focus on the impacts of marine shipping and potential oil spills from ships related to the pipeline project.
The expansion is set to nearly triple the capacity of the existing 1,150-kilometre pipeline that carries 300,000 barrels per day of petroleum products from Alberta to B.C., which will significantly increase the number of tankers carrying oil for export.
