Abstract |
The Gurley Pit site consists of a 3.25-acre pit located approximately one mile north of Edmondson, Crittenden County, Arkansas. The primary land use is agricultural. Gurley Refining Company (GRC) leased the site from R.A. Caldwell between 1970 and 1980. During this time the pit was divided by levees into three cells and used between 1970 and 1975 as a state permitted disposal site for secondary oil refining wastes including acids, oil sludges, PCBs, inorganics and spent diatomaceous wastes. In May 1978, EPA and ADPCE received complaints of chronic overflows from storm runoff. These overflows had an adverse affect on fish and waterfowl in the Fifteen Mile Bayou. The selected source control remedy included treatment and discharge of onsite surface water, offsite incineration of PCB-contaminated oil, ground water monitoring, and stabilization and onsite disposal of contaminated sludge, sediment, and soil. |
