Hazardous Waste Cleanup: Osram Sylvania Incorporated in Warren, Pennsylvania

On this page:

Cleanup Status

A Consent Assessment was signed by Osram and Pennsylvania Department of Environmental Protection (PADEP) in March 1995. The Assessment covered the incidences of cyanide exceeding the facility’s National Pollutant Discharge Elimination System (NPDES) permit requirement.

In November 1995, Osram and PADEP signed a Consent Assessment that covered a “milky white” substance coming from the Irvine Street storm water outfall on May 9, 1995.

In July 2000, EPA performed an Environmental Indicators visit and made a determination that no further corrective action is necessary at this time.

All manufacturing operations closed at the facility during period 2004-2006. All decommissioning work was completed in 2008. According to a 2009 PADEP Resource Conservation and Recovery Act (RCRA) on-site Compliance Evaluation Inspection, the Facility was in compliance. Operations continue in the engineering and research building and the Plastics Plant.

In February 2012, EPA determined to issue the Corrective Action Complete without Controls to Osram.
