MINNEAPOLIS (AP) — Several environmental groups say highly corrosive Canadian crude oil makes underground pipelines in northern Minnesota and elsewhere vulnerable to leaks and ruptures.
The groups say tar sands crude from Canada is more toxic than ordinary petroleum. The report from the environmentalists is the latest round in a fight over proposed and existing pipelines that could carry an increased amount of tar sands oil from Canada to refineries in Oklahoma, Texas and elsewhere.
According to the Alberta government, the report’s findings are misleading and inaccurate. The report was released by the Sierra Club, the Natural Resources Defense Council, the National Wildlife Federation and the Pipeline Safety Trust.
The Star Tribune says in Minnesota, Enbridge’s Alberta Clipper pipeline carries tar sands oil to Superior, Wis., where it links with another pipeline.
