Keystone pipeline to restart

U.S. regulators have allowed a Canadian company to restart its Keystone oil pipeline after completing repairs and safety tests.
Oil from the 1,300-mile pipeline that extends from Canada to Oklahoma and Illinois could begin flowing as soon as Sunday under a revised order from the U.S. Pipeline and Hazardous Materials Safety Administration. The agency approved the revision Saturday.
It has been closed since May 29, when workers reported a 10-barrel leak in Kansas. That followed a leak of 400 barrels in North Dakota on May 7.
The pipeline is owned by Calgary-based TransCanada Corp.
