The Koppers Co., Inc. (Florence Plant) site is located in Florence, South Carolina. It includes the area where a wood-treating and preserving plant has operated for several decades. EPA placed the site on the Superfund program’s National Priorities List (NPL) in 1984 because of contaminated groundwater, sediment and soil resulting from facility operations. EPA, the South Carolina Department of Health and Environmental Control (SCDHEC), and Koppers Co., Inc., the site’s potentially responsible party (PRP), have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. Site contamination does not currently threaten people living and working near the site.
In 1991-1992, EPA’s Superfund program deferred the site to EPA’s Resource Conservation and Recovery Act (RCRA) Corrective Action program. In 1996, EPA’s RCRA program deferred the site to the State of South Carolina’s RCRA program. Because of the deferral process, the state is directing site investigations and cleanup. EPA deleted the site from the NPL under its policy for deferred RCRA-lead sites. Cleanup activities under the RCRA program will continue. By monitoring the facility, treating groundwater, and cleaning up contaminated soil and sediment, EPA, SCDHEC and the site’s PRP continue to protect people and the environment from site contamination.
