PCB Spills, Warren

Site Background:
Between June 1978 and August 1978, over 30,000 gallons of waste transformer oil contaminated with polychlorinated biphenyls (PCBs) were deliberately discharged along 243 noncontiguous miles of highway shoulders in fourteen counties in North Carolina. The State conducted several investigations and feasibility studies between 1979 and 1981 and ascertained that contamination did not migrate from the spill areas into surface water, biota or groundwater.

Cleanup Progress: Construction Completed
In May, 1982, EPA and the State of North Carolina initiated a remedial action to (1) construct a landfill for disposal of PCB wastes; (2) remove, transport and dispose of contaminated soils; and (3) reconstruct the highway shoulders. Beginning in June, 1982, a Toxic Substances Control Act (TSCA) approved landfill was constructed to receive the PCB wastes. Between September and November, 1982, approximately 40,000 cubic yards of PCB-contaminated soil was removed and hauled to the new constructed landfill located in Warren County, North Carolina. Landfill construction, including capping, grading and revegetating, was complete in July 1983. The remedial action was funded by EPA and the State of North Carolina. The Site was deleted from the National Priorities List on March 7, 1986. No Five-Year Reviews are required for the Site. No further updates are warranted at this time.
