A viable PRP has voluntarily entered into an Administrative Order on Consent (AOC) with EPA and will begin a removal action soon.
Lakewood Treating is a former wood treating facility that used chromated copper arsenate (CCA) in the treating process. The Site is located at 13824 C.R. Koon Highway in Newberry, South Carolina. The facility itself is a 5-acre parcel of a 71-acre plot of land. The site consists of a small office building, a large cement drip pad, three storage tanks used for CCA solution storage, a pressure vessel used to treat the wood and an engine room. The facility began operations in 1980 and ceased operations in 2002 when the current operator abandined the facility.
DHEC conducted an emergency response at the Site in June 2002 to mitigate the threat of the containment area overflowing and contaminating the surrounding soil with CCA. DHEC pumped the dilute CCA solution into frac tanks and transported the storm water off-site. In August 2002 during a period of extremely heavy rain, the containment area did overflow. Local HazMat teams responded and dug a temporary catchment basin lined with plastic to allow for the excess spillage. Again, DHEC pumped the storm water into frac tanks and transported it off-site. Confirmation samples were taken from each frac tank, prior to transport, for volatile organic compounds (VOC) and RCRA metals analysis. The analytical data revealed the presence of chromium, copper and arsenic. Also in August 2002, DHEC completed construction of a temporary tarp roof covering the drip pad to prevent further storm water contamination.
In May 2003, at the request of DHEC, EPA conducted a removal assessment at the Site. A waste sample was taken from the solution tank for metal analysis. Soil samples were taken from around the drip pad area as well as around the lip of the containment area for metals analysis. Finally, a waste sample was taken from the wastewater in the bottom of the containment area. The results of the sampling showed little to no CCA contamination in the soils. The storage tanks however, pose a threat due to the concentration of materials inside and poor site security.
Planned Site Activities:
-Remove all hazardous substances (CCA and solution) from storage tanks;
-Decontaminate storage tanks;
-Mitigate threat of contamination and exposure from cement drip pad and containment area;
-Mitigate threat of release of CCA into ground water.
