EPA Response to Enbridge Spill in Michigan

Response History

Enbridge Energy Partners LLP (Enbridge) reported a 30-inch pipeline ruptured on Monday, July 26, 2010, near Marshall, Michigan. The release, estimated at 843,000 gallons, entered Talmadge Creek and flowed into the Kalamazoo River, a Lake Michigan tributary. Heavy rains caused the river to overtop existing dams and carried oil 35 miles downstream on the Kalamazoo River.

As the federal agency in charge of the response to the spill, EPA assumed a leadership role in the Unified Command and mobilized an Incident Management Team made up of federal, state and local agencies.

On July 27, the day after the spill was reported, EPA issued a legal order under the authority of the Clean Water Act directing Enbridge to conduct removal actions. EPA also ordered the company to produce documents and information relevant to EPA's investigation into the source, extent and nature of the oil spill.

On July 28, 2010, the spill was contained approximately 80 river miles from Lake Michigan.

July 9, 2014 - Dredging activities began at Morrow Lake, including the Delta, in June 2014 and will continue throughout the summer. To date, Enbridge has completed over 30 percent of dredging there. Some areas of the lake will be closed all or part of the recreation season to protect residents and workers from possible harm in work zones. The map above (click to enlarge) lists plans for river closures as of July 2014 and will be updated as areas open.

Dredging at the Mill Ponds impoundment was completed in May 2014, after weather delays in December 2013. All contaminated sediment at the Mill Ponds dredge pad were dewatered and disposed of by June 2014. The Mill Ponds dredge pad was removed, and MDEQ is overseeing the restoration of cover vegetation.
Overall Removals
Despite delays, substantial levels of oil and oil-contaminated materials were removed from the river under EPA’s March 2013 order. From May 2014 to the present, those removals, measured in cubic yards, were:
