About 900 barrels of crude oil leaked from an Enbridge Inc facility near Chicago this week forcing the shut-down of one of its pipelines, but the spill was contained and line restarted the same day, the company said on Friday.
The leak occurred Tuesday at a tank farm at Mokena, Illinois, near Chicago. Enbridge's Line 14, a 318,000 barrel a day conduit that carries crude to Mokena from Superior, Wisconsin, was down following the detection of the spill, the company and regulators said.
Enbridge spokesman Graham White said there was little environmental or operational impact.
"All product was contained within the tank berm, and we are continuing with clean-up and repair," White said in an email.
