The nearly 2,700-mile Keystone oil pipeline was shut down Tuesday morning after it ruptured in North Dakota, halting the flow of thousands of gallons of crude oil from Canada to refineries in the U.S.
South Bow, a liquid pipeline business that manages the pipeline, said it shut down the pipeline after control center leak detection systems detected a pressure drop in the system. The spill is confined to an agricultural field in a rural area, about 60 miles southwest of Fargo.
