EPA: Tar Sands Pipelines Should Be Held To Different Standards()  

An oil sheen appears along the shore of the Kalamazoo River in August 2012. In July 2010, more than 800,000 gallons of tar sands oil entered Talmadge Creek and flowed into the Kalamazoo River, a Lake Michigan tributary. Heavy rains caused the river to overtop existing dams and carried oil 30 miles downstream.

April 24, 2013 Up until now, the U.S. has had the same rules for all oil pipelines. But the EPA says pipelines that carry tar sands oil, like the proposed Keystone XL pipeline, should have special standards. That's because tar sands oil spills can release harmful air pollution and are vastly more difficult to clean up than conventional oil spills.
