TransCanada has restarted the Keystone oil pipeline that carries about 590,000 barrels of crude oil each day from Canada to facilities in the Midwest.
Oil began flowing again Monday afternoon. Company spokesman Shawn Howard says the system will be operated at a slightly reduced pressure for about 24 hours. Contractual delivery levels will resume in November.
TransCanada had shut down the pipeline Wednesday after tests showed possible safety issues.
