Between 1949 and 1983, the Coal Creek site was used for scrapping, salvaging, and repairing electrical equipment. During this time, oil containing PCBs was drained on to the ground.
In October 1990, a Record of Decision (ROD) was signed, specifying excavation and on-site incineration of soil with greater than 50 mg/kg PCBs. In 1992, the responsible parties (RP) entered into a Consent Decree with EPA, agreeing to implement the remedial action described by the ROD.
Remedial Action began in January 1994. The incineration system consisted of a feed system, a rotary kiln, a secondary combustion chamber (SCC), and an air pollution control system (APCS). The soil was screened before being fed to the incinerator. Over a 5-month period, the incinerator processed approximately 9,700 tons of soil. Treatment performance and emissions data collected during this application indicated that all performance standards and emissions requirements were met.
The actual cost for remediation using the incineration system was approximately $8,100,000.
