SEPTEMBER, 1983 Prepared By: SOLID AND HAZARDOUS WASTE MANAGEMENT BRANCH ENVIRONMENTAL HEALTH SECTION DIVISION OF HEALTH SERVICES NORTH CAROLINA DEPARTMENT OF HUMAN RESOURCES Introduction FINAL REPORT PCB WASTE DISPOSAL SITE WARREN COUNTY The decision to remove the approximately 40,000 cubic yards of PCB contaminated soil along public roads by the state of North Carolina was based upon the availability of a secure disposal facility. Such a facility is regulated under the Toxic Substances Control Act (TSCA) administered by the United States Environmental Protection Agency. The State of North Carolina applied for permission to utilize a 140-acre tract of land, owned by the State and located in Warren County, to construct, operate, and maintain an Annex II PCB Landfill. The site and operational plans were approved conditionally by the Environmental Protection Agency in correspondence dated June 4, 1979. Additional conditions were added on December 14, 1981. Pre-Operation Phase Activities The North Carolina Solid and Hazardous Waste Management Branch was chosen by the PCB Remedial Action Project coordinators in the Department of Crime Control and Public Safety to ensure construction and environmental monitoring compliance with the Environmental Protection Agency's approval conditions. This was made clear in a pre-construction meeting located at the site on June 10, 1982. Of primary importance in pre-operation activities was the establishment of background data on groundwater and surface water around the site. This is imperative for any long-term environmental monitoring program associated with such disposal facilities. The initial groundwater monitoring wells were constructed according to the Environmental Protection Agency approved standards when general site construction started (June 21, 1982). These wells were found to be unsatisfactory by the North Carolina Division of Environmental Management and replacement wells were installed, with the Environmental Protection Agency's approval the first week of July. One of these replacement wells was vandalized on August 5, 1982, and was again reinstalled. The Environmental Protection Agency stated that the "closing out" of unusable groundwater monitoring using cement would not jeopardize the collection of representative groundwater samples from monitoring wells in the immediate vicinity. Groundwater and surface water background chemical data was collected using the Environmental Protection Agency-approved methodologies and analytical techniques (see attachment I). Vandals damaged the 30-mil PVC liner on August 21 or August 22, 1983. Repairs were made and certified by a representative of the liner supplier. The Environmental Protection Agency inspected the repair work on August 27, 1982, and gave verbal approval at that time to continue construction. Inspections by the North .Carolina Division of Environmental Management to ensure compliance with North Carolina Sedimentation and Erosion Control Laws , were conducted on August 3, 1982, and August 25, 1982 (see attachments II and III). l Measurements of in-place saturated hydraulic conductivities of the clay liner were taken on September 12, 1982, in accordance with Environmental Protection Agency permit conditions. All measurements showed the liner to meet or exceed regulatory requirement (see attachment IV). Operation Phase Activities Placement of the contaminated soil into the prepared landfill commenced on September 15, 1982. The last load of contaminated soil was delivered on November 17, 1982. The total volume of contaminated soil was estimated at just under the projected 40,000 cubic yards. An attempt to calculate the average concentrations of PCB in the contaminated soil was made on October 7, 1982, following advice given by Mr. Ralph Jennings, Toxic Substances Section, Environmental Protection Agency. Composite samples were collected at six locations in the contaminated soil fill. Each sample consisted of a composite of material from six foot deep borings~ The average concentration of PCB's in the landfill as determined by the October 7, 1982, sampling event was 135 ppm (see attachment V). Operational phase monitoring of groundwater, surface water, and surface water sediments was conducted on October 5, 1982, and October 28, 1982 (see attachment I). Post-Operational Phase Activities Final placement of the topsoil covering over the clay and PVC cap was impeded by wet weather conditions, The North Carolina Division of Environmental Management inspected the landfill for compliance with erosion control regulations on November 5, 1982 and November 17, 1982 (see attachment II). The lack of an adequate stabilized topsoil cover resulted in the uncovering of the PVC cap due to accelerated erosion during January, 1983. The lack of the topsoil covering's weight on the PVC cap allowed decomposition gases to accumulate in bubbles under the PVC cap instead of being forced through the gas vent located at a single location at the center of the landfill. These bubbles were pierced and temporary venting pipes installed to prevent gas buildup until weather conditions allowed the contractor to repair the PVC cap and finish the placement of topsoil. Analyses of gases venting from the single permanent vent and the temporary vents by the North Carolina Department of Human Resources and the United States Environmental Protection Agency showed them to consist primarily of methane with concentrations of PCB's far below OSHA standards. Post-operational phase environmental monitoring of groundwater, surface water, and surface water sediments was permformed on November 29, 1982, and May 16, 1983. Identical monitoring events will occur each November and May until the United States Environmental Protection Agency Regional Administrator and appropriate authorities of North Carolina determine otherwise. , / The pumping of the landfill's leachate collection system to remove V rainwater that accumulated during the operational phase commenced on March 7, 1983. Over 5,000 gallons of water were removed and treated in the site's treatment works by June 1, 1983. Any effluent from the treatment works met the Environmental Protection Agency's drinking water standards for PCB's. 2 Final construction of the landfill was completed on July 14, 1983. The State of North Carolina accepted the site conditionally on July 15, 1983. All keys to locks at the facility are in the custody of the North Carolina Solid and Hazardous Waste Management Branch. The Environmental Protection Agency permit conditions identifying post-closure maintenance of the PCB landfill specify monthly inspections of the physical structures at the landfill and the leachate collection/detection sumps in addition to the twice a year environmental monitoring program. The Solid and Hazardous Waste Management Branch retains responsibility for these actions until directed otherwise by t~e Secretary of the Department of Human Resources. 3 I I \ Attachment I Ronald H.

Karnoski, Environmental Engineer )C'X' Solid & Hazardous Waste Management Branch Environmental Health Section Environmental Monitoring of the PCB Disposal Facility ST A TE HEAL TH DIRECTOR Environmental monitoring of the PCB disposal facility to identify releases from the landfill consis~ of select sampling and analyses of groundwater, surface water, and surface water sediments. Analytical parameters dictated by EPA are pH, specific conductivity, and total PCB for groundwater and surface water and total PCB for surface water sediments. All sampling, analytical, ·and security chain of· custody procedures rigidly follow EPA and N. C. Division of Health Services accepted methodologies. Locations of the four groundwater monitoring wells were designated by EPA as were the four surface water and surface water sediment sampling points (see attachment).

All analytical data is available as a part of public record. A functional aspect of the landfill's design is a mechanism to remove free liquid from the waste mass and hence eliminate material that has migration (or release) potential. Pumping of the leachate collection system cotmnenced on March 7, 1983 and continued at various intervals through June 1, 1983. ; Approximately 5,000 gallons of free liquids were removed from the landfill and treated at the landfill's treatment works. Below are dates where water analytical work was .conducted on influent and effluent water of the treat- ment system: March April May June 7, 1, 10, 1 11, 5, 25 14, 16, 21, 22, 7, 11, 12, 13, .. 23, 24, 28, 29, 30 14, 18, 19, 20, 25, 26, 27 ·--. .. .. ~ .. The highest concentration of PCB's detected in the influent water was 2.47 ppb [)..47 (10-7)% by weight]. All effluent analyses show PCB concentrations less than .1 ppb acio-8)% by weight]. Attached are allowable concentrations of PCB's in food and feed products according to 29 CFR 109(B). Effluent from the treatment works meets EPA drinking water standards. Over fifty-five private drinking water wells from residents in the area around the landfill were sampled in January of 1983. All analytical data showed no detectable levels of PCB's.
