kaydon corp.


The 40-acre Kaydon Corporation site is located in Muskegon County, Michigan. The original owner of the property, White Motors Company, produced engine blocks at the facility until Kaydon acquired the site in 1941. Kaydon has since manufactured bearings, ball bearings, and various bearing assemblies at the site. Until 1968, wastewater from plant processes, some of which contained chlorinated organic solvents, was disposed of on-site in seepage pits leading to the south branch of Ruddiman Creek. Since 1968, waste streams have been separated so that only cooling water is discharged into the creek. Ruddiman Creek flows into Muskegon Lake, which is used for recreational activities and is connected to Lake Michigan. Process wastes are removed by waste haulers, discharged to the sanitary sewer, or discharged to two on-site lined ponds. Solids settle out in the ponds and the water is then piped to the sanitary sewer. The pond sludge is periodically removed to a hazardous waste facility regulated under Subtitle C of the Resource Conservation and Recovery Act (RCRA). Groundwater investigations began in October 1982, when the Michigan Department of Natural Resources (MDNR) requested that Kaydon perform a hydrogeologic investigation of the area. The investigation revealed volatile organic compounds (VOCs) in the groundwater leaving the Kaydon property. In 1987, Kaydon submitted an initial Remedial Action Plan (RAP) for on-site groundwater (Operable Unit #1 or OU1) to the state of Michigan. Michigan approved the RAP. However, the document was later reevaluated due to the passage of the Natural Resources and Environmental Protection Act of Michigan (NREPA) in 1994. The United States Environmental Protection Agency (EPA) proposed the Kaydon site for the National Priorities List (NPL) on June 24, 1988, and finalized the site on the NPL on February 21, 1990. After the site was placed on the NPL, the State continued to work with Kaydon to define the extent of contamination. In 1995, restructuring within the State of Michigan transferred responsibility for remedial activities from MDNR to the newly-created Michigan Department of Environmental Quality (MDEQ). EPA continues to have a support role at the site. Site Responsibility This site is being addressed through state and potentially responsible party (PRP) actions.
