The North Penn-Area 7 site consists of five unconnected industrial facilities situated on approximately 650 acres. The 1.1-acre Spra-Fin facility is one of the five facilities. Prior to 1963, the facility was a warehouse for paper products. In 1963 Spra-Fin, Inc., purchased the property and operated a metal manufacturing and finishing business on it until 2004. Spra-Fin used and stored trichloroethene (TCE) on site, mainly for degreasing metal products. The facility stored TCE in an underground storage tank until 1980 when it moved the chemical to an above-ground tank. The main sources of the contamination include underground and surface leaks and spills from both the underground and above-ground tanks. In addition to TCE, chromium is a contaminant found to pose an unacceptable risk at the facility.
Current Site Status and Cleanup Actions to Date
- In 1984 Spra-Fin, Inc., took the following actions to address soil contamination:
- Removing the underground storage tank and replacing it with a 500-gallon above-ground tank completely enclosed in a block structure capable of containing a spill of the entire tank;
- Excavating approximately 60 cubic yards of the most heavily contaminated soil and disposing of it in a sanitary landfill. After the excavation, an underground drainage system was installed in the excavation pit. The system collects the groundwater that is ultimately discharged to the sewer system; and
- Pumping continuously the two deep wells at the facility.
- In 2004, EPA approved the cleanup plan for the Spra-Fin facility. The plan calls for excavation and off-site treatment and disposal of contaminated soils.
- EPA's emergency response program responded to the facility in 2005. The emergency activity included disposing of hazardous substances and wastes from five process tanks and approximately 1,000 one-to five-gallon containers of solvents, paints and flammable liquids.
- EPA continues to monitor the Spra-Fin facility to ensure there is no immediate threat to human health during the cleanup work.
- EPA initiated work to address contaminated soil excavation and off-site disposal.
Current Funding Status
- EPA obligated approximately $1.0 million for cleanup activities at this site in Fiscal Year 2007.

EPA removed hazardous substances and wastes from five process tanks, 100 drums of spent powder coat and some 1000 one- to five-gallon containers of solvents, paints and flammable liquids.
In 2004, EPA approved the cleanup plan for the facility and also has approved the design for the cleanup that calls for excavation and off-site disposal of contaminated soils.
