In the largest spills on the continental US in nearly a decade, more than half a million gallons of oil leaked from the Keystone Pipeline in Kansas, just south of the Nebraska border, contaminating a creek that ran by the pipeline site, Reuters reports.
Equivalent to about 14,000 barrels, the leak constitutes a small portion of the overall volume the pipeline, that carries more than 600,000 barrels per day from Alberta, Canada to the Gulf Coast of Texas.
This is the third large spill measuring thousands of barrels of oil to hit the 2,100-mile pipeline since it opened in 2010. The cause of the leak is unknown.
