Enbridge: Mich. oil spill cleanup may cost $700M

MARSHALL, Mich. — A pipeline company is increasing its estimate of the cleanup cost of last year's more than 800,000 gallon oil spill that contaminated southern Michigan's Kalamazoo River.

Enbridge said Monday in a filing with the U.S. Securities and Exchange Commission that cleanup could cost about $700 million. The Battle Creek Enquirer and the Kalamazoo Gazette report that's about 20 percent more than the previous $585 million estimate.

The Calgary, Alberta-based company says that would be more than the $650 million that it can be reimbursed by insurance.

The estimate doesn't include any possible fines or penalties.

Officials have said that the cleanup effort from the July 2010 spill could extend beyond this year. The spill occurred from a portion of an Enbridge Inc. pipeline running from Griffith, Ind., to Sarnia, Ontario.
