KALAMAZOO — A day after officials from the U.S. Environmental Protection Agency discussed the next phase of work to remove soil and sediment contaminated with polychlorinated biphenyls, or PCBs, from the Kalamazoo River near the city of Plainwell, the agency made the project official on Tuesday.
Work will begin in August and be completed in late 2010 on a project to remove 12,000 cubic yards of PCB-laden material near a water diversion dam about 3.5 miles upstream from a recently completed, two-year PCB removal project, according to a statement from the EPA.
EPA officials were less than specific on the details of the project yesterday, waiting to officially announce the project after the administrative order on consent was signed by Georgia-Pacific Corp., which will pay for the work, which will cost the company $10 million.
About 90 percent of the PCBs in the area will be removed, the statement says. Waste with PCB concentrations at 50 parts per million or more will be sent to a chemical waste landfill. Waste with levels below 50 ppm will be sent to commercial landfills.
Around 80 miles of the river – from Morrow Dam just east of the city of Kalamazoo to Saugatuck on Lake Michigan – was declared a Superfund site in 1990. PCBs are of concern because they concentrate in the food chain resulting in health hazards to people, fish and wildlife. Congress banned the manufacture of PCBs in 1976 and PCBs still in use are strictly regulated.
