The Environmental Protection Agency says most of the oil still remaining from a July 2010 pipeline leak in
West Michigan sits on the floor of the Kalamazoo River and along about 200 riverbank sites.
EPA on-scene coordinator Ralph Dollhopf tells the Battle Creek Enquirer that cleanup work has yet to be done on those riverbanks near Marshall, about 60 miles southeast of Grand Rapids.
Enbridge Inc. has been given until October 20th to submit revised plans for additional cleanup work. More than 800,000 gallons of oil leaked into the river and Talmadge Creek. About 766,000 gallons of oil has been collected.
Enbridge has said it was increasing its estimate of the cleanup cost by about 20 percent to $700 million.
The pipeline runs from Griffith, Ind., to Sarnia, Ontario.
