CHICAGO -- U.S. Environmental Protection Agency officials say the leak from an oil pipeline outside Chicago has stopped.
WFLD-TV reports that an inch-and-a-half hole was found on the bottom of the 34-inch diameter pipe, owned by Enbridge Energy Partners.
The pipeline break was discovered Thursday in Romeoville along Enbridge's "6A" pipeline, which runs 465 miles from Superior, Wis. to Griffith, Ind.
Officials say repair of the pipe and cleanup are under way.
Enbridge also owns a pipeline that ruptured in Marshall, Mich., in July and leaked at least 800,000 gallons of oil into a waterway there.
Analysts say the latest leak has caused a spike in gas prices across the region.
