It regulates the engineering technique called hydraulic fracturing, or fracking.

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.
