This administrative order requires Enbridge to do additional dredging in Michigan's Kalamazoo River to clean up oil from the company's July 2010 pipeline spill. EPA's order requires dredging to remove recoverable submerged oil in sections of the river above Ceresco Dam, upstream of Battle Creek and in the Morrow Lake Delta. This dredging will prevent the submerged oil from migrating to downstream areas where it will be more difficult or impossible to recover.
