The 2,700-mile Keystone Oil Pipeline was shut down for several hours after a rupture was discovered in North Dakota Tuesday. Thousands of barrels of crude oil from Alberta flow through the pipeline. This particular rupture, about 60 miles southwest of Fargo, is the latest spill from the controversial pipeline; a stretch of it, the Keystone XL pipeline that was to run through Montana, was never built.
It was over three years ago when nearly 13,000 barrels of crude spilled into a creek in Kansas.
