The Department of Toxic Substances Control (DTSC) is considering the renewal of the Hazardous Waste Facility Permit (Permit) for Travis Air Force Base (AFB). This Permit will allow Travis AFB to store hazardous waste generated through aircraft and base infrastructure operation and maintenance activities. The hazardous waste is stored in the Travis AFB Hazardous Waste Storage Facility (Facility), which consists of two units: Building 1365 and the Tank Farm. Building 1365 is a container storage building that stores 55-gallon drums in 15 different bays at the capacity of 56,760 gallons (equivalent to approximately 1,032 55-gallons drums). The Tank Farm holds six Onground Tanks, at the capacity of 2,500 gallons per tank. The changes to the proposed Permit include the following minor operational changes:
• Addition of 49 (36 EPA-listed and 13 California-listed) new categories of allowable hazardous waste at the existing storage facilities;
• Addition of operating flexibility for all bays within Building 1365 to allow storage on any permitted hazardous waste without restriction except as required by regulations to meet hazard protection standards; and
• Allow two existing Onground Tanks in the Tank Farm to store jet fuels contaminated with only water (Retrograde Material) that may be resold.
