4150 A. OLD BERWICK ROAD

The Safety Light Corporation Site is located on 10 acres in South Centre Township near Bloomsburg, Columbia County, Pennsylvania. The site is bounded on the north by Old Berwick Road, on the east and west by residential areas, and on the south by the North Branch of the Susquehanna River. Past activities at SLC include the manufacturing of self-illuminated watches and instrument dials, smoke detectors, neutron sources, exit signs, and other merchandise containing radioactive materials, as well as activities regulated under the Nuclear Regulatory Commission (NRC). From the 1940s to the 1960s, manufacturing at the property used several radionuclides, including radium. Prior to 1980, activities involving radium-226 and most other radionuclides ceased, and tritium remained as the only radionuclide used in the manufacturing of self-illuminating devices, primarly exit signs. Waste generated at SLC includes solid and liquid waste streams contaminated with radioactive materials, including radium-226, strontium-90, cesium-137, and tritium. In 2005, the EPA added the site to the National Priorities List (NPL) of most hazardous waste sites in the country, making the site eligible for federal cleanup.
