While dredging is underway, 12 miles of the river will be temporarily closed. Enbridge will dredge approximately 350,000 cubic yards of contaminated sediment during this phase of the cleanup, EPA officials said. During the past three years, nearly 190,000 cubic yards of oil-contaminated material and 1.15 million gallons of oil have been recovered from the river, officials said. More than 800,000 gallons of diluted bitumen, a sludgy, heavy crude oil derived from Canadian tar sands that’s diluted with thinners, spilled when a 30-inch pipeline operated by Enbridge ruptured near Marshall, on July 25, 2010. The spill contaminated Talmadge Creek and 35 miles of the Kalamazoo River downstream. The diluent in the oil vaporized in the leak, putting benzene and other harmful chemicals into the air. Much of the remaining tar sands oil combined with river sediment. freep/article/20130730/NEWS06/307300120/New-round-of-dredging-in-Kalamazoo-River-after-2010-oil-spill
