Redevelopment at the Site

The 32-acre Centre County Kepone Superfund site is located in State College, Pennsylvania. The chemical manufacturing facility on site produced pesticides and other chemicals between 1959 and 2004, when the plant closed. The site operator disposed of wastewater and sludge in drums and lagoons on site. Site investigations found that hazardous materials leaked from the lagoons, contaminating groundwater, soil, surface water and drainage ditch sediments. EPA placed the site on the Superfund program’s National Priorities List (NPL) in 1983. Completed in 1999, cleanup activities included installing a groundwater treatment system; upgrading surface water management controls; and removing and disposing of contaminated soil, sediment and waste materials. In 1998, construction of a shopping center next to the site property included cleanup and redevelopment of part of the drainage ditch into a storm drainage system, a sidewalk and a vehicle access lane under an EPA order. After EPA changed the site’s cleanup plan for soil in 2003, a soil vapor extraction system was installed to remove contaminants from subsurface soil at the site. EPA deleted an 8-acre area of the site referred to as the “Administration Parcel” from the NPL in 2004. This deleted area includes the administration building, a parking lot and open areas.

The site owner sold about 19 acres of the site property to a local developer. Former on-site warehouses are currently used by a roofing company for material storage and sales. A heating and cooling supply company also operates on part of the redeveloped property. Interim uses are underway at the site while the potentially responsible party explores long-term redevelopment options for the property. EPA is currently overseeing ongoing groundwater treatment and monitoring, the intermittent operation of the soil vapor extraction system, and the site’s ongoing vapor intrusion investigation.

Economic Activity at the Site

As of December 2019, EPA had data on 2 on-site businesses. These businesses employed 12 people and generated an estimated $6,653,000 in annual sales revenue. View additional information about redevelopment economics at Superfund sites.

Activity and Use Limitations

At this site, activity and use limitations that EPA calls institutional controls are in place. Institutional controls play an important role in site remedies because they reduce exposure to contamination by limiting land or resource use. They also guide human behavior. For instance, zoning restrictions prevent land uses – such as residential uses – that are not consistent with the level of cleanup. For more background, see Institutional Controls.

Institutional controls are in place to prevent use of groundwater, eriosn control and limit uses of some parcels for future development. Additional information about the institutional controls is available in the 2014 Five-Year Review (PDF) (on page 27).
