TransCanada Corp. says its pipeline that transports crude oil from Canada through seven states is shut down.
Spokesman Terry Cunha (KOON'-yuh) said Wednesday that the 2,148-mile-long pipeline was stopped for "mechanical issues." He did not elaborate.
Crude began flowing through the $5.2 billion pipeline last year. It's designed to carry 590,000 barrels of oil daily across Saskatchewan and Manitoba, and through North Dakota, South Dakota, Nebraska, Kansas and Missouri on the way to refineries Patoka, Ill. and Cushing, Okla.
The shutdown comes as the Calgary-based company seeks to build the $7 billion Keystone XL pipeline that would carry tar sands oil from Alberta, Canada, to refineries in Texas. That project is awaiting U.S. State Department approval.
