Kettleman Hills Facility Permitting Activities

Chemical Waste Management, Inc., operates the Kettleman Hills Facility located at 35251 Old Skyline Road off of Highway 41, PO Box 471, Kettleman City, California, 93239.

Waste disposal activities began at the facility in June 1975 when Kings County issued a permit to McKay Trucking for a liquid waste disposal site. In 1979, Chemical Waste Management, Inc., a subsidiary of Waste Management, Inc., acquired the property and began expanding the facility while applying for and receiving a variety of permits. In 1987, the United States Environmental Protection Agency (US EPA) and the California Department of Health Services (currently Department of Toxic Substances Control or DTSC) issued a joint operating permit for the facility.

In September 1993, and again in June 2003, DTSC renewed the Hazardous Waste Management Permit. The permit includes both treatment and storage operations.

Trucks deliver waste to Chemical Waste Management, Inc. Inspection of hazardous wastes received is completed in two stages. The first stage is at the receiving scale where arriving loads are compared to the shipping papers or manifests. At stage two, Chemical Waste Management tests a portion of the hazardous wastes from each truck in order to categorize the waste received and verify that materials are exactly as described in the manifest. The following units are located at the facility:

  • Drum Storage Unit: Storage in containers.
  • PCB Flushing/Storage Unit: Transfer/Storage of liquid PCB wastes from bulk containers to the 10,000-gallon storage tank, or to U.S. Department of Transportation (DOT)-approved metal drums for eventual off-site treatment/disposal.
  • Bulk Storage Units 1 and 2: Temporary storage of stabilized/unstabilized waste prior to land disposal, treatment or shipment off-site.
  • Final Stabilization Unit: Processing of various solid, semi-solid and selected liquid wastes not suitable for landfill disposal, solar evaporation or other management method employed at the Facility, by mixing with stabilization reagents.
  • Surface Impoundments or ponds P-9, P-14 and P-16: Treatment by solar evaporation.
  • Landfill units B-18: Land disposal.

Other units present at the facility include the chemical analysis laboratory and a vehicle wash station.

On December 12, 2008, Waste Management submitted a Class 3 permit modification application for their Hazardous Waste Facility Permit. The application proposes to expand the capacity of Landfill Unit B-18 from 10,700,000 cubic yards to 15,700,000 cubic yards.
