Document Description
DTSC has issued West Contra Costa Sanitary Landfill, Inc (WCCSL) an emergency permit to implement additional hazardous waste treatment and storage operations not authorized in the Hazardous Waste Facility Post-Closure Permit, which was issued to WCCSL by DTSC on July 9, 2003. The treatment and storage is for removal of leachate located within and below the landfill. The Hazardous Waste Facility Post-Closure Permit requires the WCCSL to remove and treat leachate within the landfill. It has been determined that the Leachate Extraction and Treatment System has not been operating adequately to establish and maintain an inward hydraulic gradient within the landfill, thus, causing releases of hazardous waste leachate from the landfill. In order to remediate the existing imminent and substantial endangerment, DTSC has required WCCSL to pump the hazardous waste leachate from the subsurface at 21,600 gallons per day as required in the February 2, 2006, DTSC Enforcement Order, Docket HWCA 20061079.
