Here is a condensed timeline of the Philip Services Corporation (a/k/a ThermalKEM) Site.
Industrial Chemical Company, Inc. and Quality Drum Company, Inc. (operating on separate property parcels) received waste solvents from other facilities. These operators stored the solvents in drums and tanks, and recovered solvents through distillation. Wastes that were left after the distillation process (called still bottoms) were sent to a local landfill.
A hazardous waste incinerator was installed to treat still bottoms (distillation waste). The facility also began to process a broader variety of waste streams.
Quality Drum and Industrial Chemical merged.
Stablex South Carolina, Inc. acquired all four parcels of the facility property. At that time, approximately 26,000 drums of waste and 200,000 gallons of bulk liquid waste were stored onsite.
American NuKEM Corporation purchased the stock of Stablex.
Stablex South Carolina, Inc. began operating under the assumed name of ThermalKEM, Inc. ThermalKEM operated as a hazardous waste incinerator and storage facility under RCRA interim status (EPA I.D. No. SCD044442333).
Philip Services Corporation (PSC) purchased the stock of Stablex/ThermalKEM and its subsidiary, Petro-Chem, and took over operation and management of the facility.
PSC ceased operation of the hazardous waste incinerator. However, PSC continued to operate the facility as a fuel blending, storage, and transfer facility until 1999. During the years of operation, the facility sustained two large structural fires.
PSC submitted an incinerator closure plan.
PSC filed for bankruptcy protection.
DHEC assumed environmental management responsibilities. As part of the bankruptcy action, a custodial trust account was established to provide some funding for environmental activities. It was determined that the funds in the custodial trust account would be inadequate to complete any remedy. DHEC began initial, investigation and cleanup activities.
DHEC began a remedial investigation, which included several phases to determine the source, nature, and extent of soil and groundwater contamination. DHEC installed more than 50 groundwater monitoring wells and conducted comprehensive sampling..
DHEC issued its Remedial Investigation Report . The findings identified extensive areas of soil and groundwater contamination.
DHEC completed a Feasibility Study that evaluated cleanup alternatives.
DHEC identified its preferred cleanup alternative in its Proposed Plan for remedial action.
DHEC's Proposed Plan meeting.
Extended to 11/26/14
Future activities include responding to any comments received during the Proposed Plan comment period and issuing a Record of Decision, which documents selection of the final cleanup remedy. DHEC expects a group of potentially responsible parties (PRPs) will fund and perform the cleanup with DHEC's oversight.
