Abstract:
SITE HISTORY/DESCRIPTION: The 200-acre Kin-Buc Landfill consists of several inactive disposal areas and is located in Edison Township, Middlesex County, New Jersey. Land use in the area is predominantly industrial and commercial, with some residences within 2 miles north of the site. No drinking water supply wells are located within a 2-mile radius of the site. The Kin-Buc site includes three landfill mounds: Kin-Buc I, Kin- Buc II (directly north of Kin-Buc I), and Mound B (southwest of Kin-Buc I and adjacent to the Raritan River). Additionally, the low-lying Edmonds Creek/Marsh area is situated between Kin-Buc I and the adjacent Edison Landfill and a wetlands area. Portions of the Kin-Buc site lie within both the 100-year floodplain of the Raritan River and a coastal zone. From 1947 to 1977, Kin-Buc accepted industrial and municipal waste, including solvents, waste oils, paint sludge, cyanides, metal stripping wastes, and paint thinners. An estimated 70 million gallons of liquid waste and at least 1 million tons of solid waste were disposed of at Kin-Buc between 1973 and 1976 alone. As a result of an oil spill in 1976, EPA conducted an investigation of the property. In 1980, clean-up activities were initiated under the Clean Water Act and included removal, treatment, and disposal of leachate and drummed waste. Also in 1980, Kin-Buc was ordered to cap Kin- Buc I and II. A 1988 ROD addressed source control remediation in mounds I and II, the low-lying area, and Pool C as OU1. This ROD addresses a final remedy for OU2 which includes sediment and ground water in the Edmonds Creek wetlands area, Mill Brook/Martins Creek, Mound B, and the low-lying area. The primary contaminants of concern affecting the sediment, ground water, and surface water are VOCs, including benzene and xylenes; other organics, including PAHs and PCBs; and metals, including arsenic.
PERFORMANCE STANDARDS OR GOALS: Chemical-specific excavation goals for sediment are based on EPA's evaluation of bioavailability, Office of Water methods, and remediation goals at other Superfund sites and include PCBs at 5 mg/kg. EPA believes that a PCB-driven remedial action will also affect reduction of the other contaminants onsite, such as metals and PAHs.
INSTITUTIONAL CONTROLS: Not provided.
Remedy:
SELECTED REMEDIAL ACTION: The selected remedial action for this site includes excavating 2,200 cubic yards of contaminated sediment with PCB levels above 5 mg/kg using excavation methods selected to control surface water flow and minimize impact to wetlands; dewatering, consolidating, and disposing of the sediment onsite within the OU1 containment area; actively restoring 1.36 acres of affected wetlands in Edmonds Creek/Marsh using a program to be developed during the RD stage; maintaining the Mound B cover; allowing natural attenuation to reduce contaminant concentrations in the ground water to acceptable levels; and conducting long-term monitoring of ground water and surface water. If EPA determines that disposal of OU2 sediment in the OU1 containment area will delay construction of the OU1 remedy, a contingency remedy will be implemented, which provides for offsite disposal of sediment at a chemical waste facility. The estimated present worth cost for this remedial action is $4,314,900, which includes an annual O&M cost of $67,100 for 30 years.
