Enbridge Energy Partners reported that clean up was continuing on a crude oil leak, which was confirmed Saturday on Line 2b on the Enbridge Lakehead Pipeline System. An initial spill estimate of approximately 3,000 barrels (126,000 gallons) of light crude oil was reported to federal and state regulatory authorities.
The leak, which is located in Pembina County, North Dakota, was detected by the Enbridge pipeline control center at approximately 11:30 p.m. CT, Friday, Jan. 8. The pipeline was immediately shutdown and isolated by closing valves upstream and downstream of the suspected leak site. The leak is contained within the Enbridge right-of-way, and no water or wildlife have been affected.
Enbridge employees and contractors are on site removing crude oil from the affected section of the pipeline right-of-way. The cause of the leak is under investigation by Enbridge and pipeline regulatory authorities.
Line 2b runs from Cromer, Manitoba, to Superior, Wisc. The segment of Line 2b between Cromer and Clearbrook, Minn. likely will remain out of service through Monday, Jan. 11. Oil that was designated for transportation on Line 2b is being moved on other Enbridge pipelines that parallel Line 2b until service is restored on that pipeline. Line 2B, from Clearbrook to Superior, Wisc., is continuing to move volumes sourced from Enbridge's North Dakota System as well as re-routed volumes from upstream of Cromer on Line 2b.
