Abstract |
The 17-acre Charles Macon Lagoon & Drum Storage site is a former oil recycling and antifreeze manufacturing facility in Richmond County, North Carolina. The site overlies an unconfined aquifer, and surface runoff discharges to Pee Dee River, which runs 1 mile west of the site. From 1979 to 1982, unpermitted waste oil recycling was conducted at the facility using a large boiler to separate the waste oil from other wastes. Site features resulting from these activities include drum storage areas, 12 unlined or partially lined oil/water waste storage lagoons, buildings, 2 truck tankers, and 14 tanks. In a 1981 EPA RCRA compliance inspection of the Macon site, 10 violations of RCRA regulations were cited. Recent investigations, however, revealed that site soil and ground water still pose a threat, particularly downgradient of source areas such as lagoon areas. The Record of Decision (ROD) addresses soil, vessels containing hazardous materials, and ground water, which is the principal threat at the site, and is a final remedy. The primary contaminants of concern affecting the soil, sludge, debris, and ground water are VOCs including PCE, TCE, toluene, and xylenes; other organics including PAHs; and metals including arsenic and chromium. The selected remedial action for the site is included. |
