NPL Site Narrative for Occidental Chemical Corp./Firestone Tire & Rubber Co.

Lower Pottsgrove Township, Pennsylvania

Federal Register Notice:  October 04, 1989

Conditions at proposal (June 24, 1988): The Occidental Chemical Corp./Firestone Tire & Rubber Co. Site is in Lower Pottsgrove Township, Montgomery County, Pennsylvania. Occidental has manufactured plastic resins such as polyvinyl chloride (PVC) at the facility since 1980, when it purchased the site from Firestone Tire & Rubber Co. Firestone had produced both PVC and tires on the site since 1945.

Both companies disposed of their waste on approximately 23 acres of the 250-acre property. The disposal area consists of an inactive 17-acre landfill, an active 6-acre landfill, four inactive seepage lagoons, and two active lined lagoons. The four seepage lagoons received PVC waste during 1945-74. The sludge from the lagoons was periodically removed and disposed in the now inactive 17-acre landfill. In 1973, the Pennsylvania Department of Environmental Resources (PA DER) issued a permit to Firestone to operate the 17 acres as a sanitary landfill. In 1985, Occidental closed it under a PA DER closure plan; the landfill was capped with a plastic cover, 2 feet of earth and topsoil, then seeded.

Currently, PVC waste is pretreated and the effluent discharged to the municipal sanitary sewer system. Most of the sludge goes to the active landfill, with the remainder going to the two lined lagoons, which were constructed in 1974.

Trichloroethylene, trans-1,2-dichloroethylene, and vinyl chloride were detected in on-site wells in tests conducted in 1985 by EPA. An estimated 14,500 people obtain drinking water from public and private wells within 3 miles of the site.

The site is in the floodplain of the Schuylkill River, which is used for recreational activities within 3 miles downstream of the site.

EPA has conducted a search to identify parties potentially responsible for wastes associated with the site.

Since 1976, Occidental has been pumping ground water to the surface, treating it to remove the contaminants, and reusing the treated water for processing purposes.

Status (October 4, 1989): Occidental has submitted a proposal to EPA to conduct a remedial investigation/feasibility study to determine the type and extent of contamination at the site and identify alternatives for remedial action.
