Workers survey around pipe to start right-of-way construction for the Trans Mountain Expansion Project, in Acheson, Alta., on Dec. 3. 2019. Work on the 1,150-kilometre twinning was temporarily stopped in December as the company re-evaluated safety practices following injuries and at least one death. (THE CANADIAN PRESS/Jason Franson) The expansion project–essentially a twinning of the 1,150 original line that was built in 1953–aims to upgrade delivery capacity from approximately 300,000 barrels per day to 890,000 barrels per day. In a statement released Monday, Trans Mountain said it conducted “a thorough review and examination” of its safety procedures following the voluntary shutdown.. “The company and its contractors identified opportunities for enhancements to safety measures, some of which may have been contributing factors to the events of the past few months,” the corporation said.
