(AP Photo/Susan Walsh) - The Canadian PressA congressman from Washington State says the U.S. Coast Guard should review and update oil spill response plans as news of a planned pipeline from Alberta to B.C. would increase oil tanker traffic in the Salish Sea. Rep. Rick Larsen says he sent a letter to a top U.S. Coast Guard official this week seeking details about co-ordination efforts around a Canada-U.S. pollution contingency plan. Larsen says the contingency plan is important after the announcement of a new oil pipeline from Alberta to B.C. He says the pipeline will bring more oil tanker traffic to the waters off his state, and "with it the risk of catastrophic oil spills."
