Superfund Site: RIVER ROAD LANDFILL (WASTE MANAGEMENT, INC.), HERMITAGE, PA
Superfund Site Profile
The River Road Landfill site, located in Mercer County, Pennsylvania, is a 102-acre inactive landfill that operated from 1962 until 1986. The landfill accepted municipal and industrial wastes, including foundry and metal processing waste, polychlorinated biphenyl (PCB) wastes, asbestos, and residues from tank car cleaning. Ownership of the landfill was transferred several times over the years. The current owner, Waste Management of Pennsylvania, Inc. purchased the landfill in 1980, using it only for the disposal of non-hazardous industrial wastes. The Pennsylvania Department of Environmental Protection (PADEP) fined the company for several waste disposal violations, including discharging leachate into surface waters and operating a solid waste disposal area without a permit. The facility received a permit in 1984 for solid waste disposal but stopped receiving waste in May 1986. In 1987, Waste Management of Pennsylvania carried out a PADEP approved landfill closure. Approximately 4,500 people live within a mile of the site, and 9,000 people live within three miles. Two sedimentation ponds catch runoff from the site and also control spillways draining into the Shenango River, which is located next to the landfill's southern border. This site was proposed to the National Priority List (NPL) on January 22, 1987 and formally added to the list October 4, 1989.
