JEFFERSON COUNTY, Wis. - The Wisconsin Department of Natural Resources (DNR) announced on Tuesday, Dec. 17 is investigating a spill of crude oil from a pipeline along Enbridge Energy’s Line 6 in the town of Oakland – about four miles east of the village of Cambridge in Jefferson County.
A news release says on Nov. 11, the DNR received a report from Enbridge of a two-gallon spill of crude oil at Enbridge's Cambridge Station. Enbridge also notified the National Response Center (NRC) and the Pipeline and Hazardous Material Safety Administration (PHMSA).

On Nov. 14, Enbridge revised the estimated spill quantity from two gallons to three barrels (126 gallons).
