Oil tanker traffic off the British Columbia coast is coming under scrutiny as U.S. authorities launch a review of proposed increases in oil exports out of Vancouver harbour.
A legislative amendment proposed by Washington State Sen. Maria Cantwell and signed into law by President Barack Obama gives the U.S. Coast Guard six months to conduct a risk assessment of potential expansion of oil pipeline capacity to the West Coast.
The review comes in light of Kinder Morgan’s plan to twin its 1,150-kilometre Trans Mountain pipeline system between Strathcona County, Alberta, and Burnaby, B.C. If approved, the expansion would increase the nominal capacity of the system from 300,000 barrels per day to 750,000 barrels per day.
“A supertanker oil spill near our shores would threaten Washington State’s thriving coastal economy and thousands of jobs,” Cantwell said in a statement. “This bill will provide crucial information for Washington coastal communities by requiring a detailed risk analysis within 180 days.”
The review will assess the risk of transporting oil via tanker and barge through the Salish Sea waterways, which encompass both U.S. and Canadian waters between southern Vancouver Island and the mainland.
The Coast Guard will also examine regulations that apply to oil tankers in U.S. waters compared to Canadian waters, and analyze whether extra safety measures are needed to transport what Cantwell calls “tar sands” oil.
