| Abstract |
The site, a defunct waste solvent reclaiming/processing facility, is located on three and three-quarters acres of land in Greenup, IL, and includes thirteen steel storage tanks containing mixtures of waste oils contaminated with PCBs and organics, sludges, spent caustics, spent acids, contaminated water and waste products. The tanks have a history of failure, creating a significant threat of hazardous substance release. In addition, the site includes four storage lagoons of contaminated sludge and soil which have a history of overflow problems. The site is underlain by ten feet of silty material with a high permeability; beneath this silt layer lies a sand and gravel aquifer which has been contaminated. The site has a pronounced slope toward a river, is in a flood plain, and includes porous soil and high ground water table. The cost-effective Initial Remedial Measure (IRM) selected for this site includes: off-site transportation and disposal of all contaminated bulk liquids, oils and drums at a RCRA-approved facility. Additional actions will include a cooperative agreement to conduct an RI/FS for soils, sludges and ground water contamination, and the preparation of another ROD to address remedial actions necessary to mitigate problems caused by the remaining contaminants. The capital cost of the IRM is estimated to be $111,100. |
