| Abstract |
The 40-acre L.A. Clarke site, located in Spotsylvania County, Virginia, began wood preserving operations in June 1937, which have continued to date. During the past 50 years, creosote contaminated soil and sediments resulted from facility operations spills, waste streams entering the drainage ditches, and onsite disposal. Historical aerial photography indicates that from at least 1953 through 1974 wastewater was disposed into two concrete-lined pits. Overflow from the concrete pits was stored in an earthen pit. Excess water was discharged to drainage ditches and sprayed on the ground around the storage yard to control dust. In 1975, L.A. Clarke & Son, Inc. was issued a National Pollution Discharge Elimination System (NPDES) permit for outfalls from two onsite drainage ditches which is still in effect. Phenol is the only toxic contaminant regulated by the permit. In 1980, L.A. Clarke & Son, Inc. was classified under RCRA as a treater of hazardous waste. As part of a State-mandated remedial action in 1982, approximately 1,400 cu yd of soil was excavated from the processing area. |
