mig/dewane landfill


The 50-acre MIG/DeWane Landfill site is located about one-fifth mile east of the city of Belvidere and one-half mile north of U.S. Business Route 20 in Boone County, Illinois. Approximately 1,500 people live within one mile of the site. The MIG/DeWane site consists of a 47-acre landfill and leachate impoundment system that was operated by various entities from 1969 until its abandonment in 1988 by M.I.G. Investments, the final operator. The landfill was a permitted municipal landfill and during its operating period it received household and municipal wastes as well as industrial wastes including paint sludge, volatile organic chemicals (VOCs), asbestos, and liquids containing heavy metals. In 1984, the U.S. Environmental Protection Agency (EPA) inspected the site and determined that the landfill waste and leachate were contaminating site soil, groundwater, and sediment and that the potential existed for surface water contamination and direct exposure of humans to contaminants. After the landfill was closed in 1988, Illinois EPA inspected the site in 1989 and found that the site was not properly closed and capped, noting that there was exposed waste and a 5 to 10-acre depression in the middle of the landfill. The depression collected water that drained into the landfill and resulted in over one hundred leachate seeps with some leachate flowing off site towards the nearby Kishwaukee River. Illinois EPA's inspection also determined that the leachate surface impoundment was about to overflow and/or breach, which would potentially cause serious environmental impacts to the river. In 1989 and 1990, Illinois EPA and EPA, in two separate emergency actions, removed approximately 155,000 gallons of leachate from the site. EPA placed the MIG/DeWane Landfill site on the Superfund National Priorities List in 1990. Site Responsibility The MIG/DeWane Landfill site is being addressed through potentially responsible party (PRP) actions under state and federal oversight.
