The study examined the different ways to transport Alberta's bitumen, a molasses-like crude oil, over U.S. land and water. Those included rail, the proposed Kinder-Morgan Trans Mountain pipeline to Vancouver, the Keystone XL line to Texas from Alberta, and Northern Gateway.
"Most oilsands products are transported to market via existing and proposed pipelines; however, a sharp increase in the use of rail and marine transport can be expected while new pipelines are constructed to match the increased production of oilsands products," the report says.
It was written by six experts at the University of Washington and supervised by Prof. Robert Pavia of the university's School of Marine and Environmental Affairs.
"While there are many arguments about the level of risk, no one believes the risk is zero," Pavia told The Canadian Press, adding that he was speaking personally. "In my mind it's not a question of whether a spill will occur, but how well-prepared we are for a spill once it does occur."
In the case of Northern Gateway, not only might there be potential to harm Washington state shores, there could be hazards from tankers leaving Kitimat, B.C., to travel through the waters of Alaska, near the Aleutian Islands to Asia. The proposed 1,177-kilometre-long pipeline would carry 525,000 barrels of bitumen daily from Alberta to the northern B.C. port.
