Document Description
The California Department of Toxic Substances Control (DTSC), pursuant to
authority granted under California Code of Regulations, Title 22, Division 4.5, Chapter 20, is approving an addendum to a previously adopted Negative Declaration for the renewal of a Hazardous Waste Facility Permit (Permit) for Corteva Agriscience LLC – Pittsburg Operations (Corteva), formerly The Dow Chemical Company – Pittsburg (Facility), for ten additional years. This Permit covers the areas of the Facility’s treatment units comprised of two boiler and industrial furnaces, three hazardous
waste storage tanks, and the furnaces’ associated hydrochloric acid recovery and air pollution control systems. The Facility is located at 901 Loveridge Road in Pittsburg, CA 94565. The Facility requests a permit renewal to continue current operations with no proposed changes at the Facility.
The Permit would authorize the continued operation of hazardous waste treatment and storage units consisting of two Boilers and Industrial Furnaces (BIFs), specifically Halogen Acid Furnace (HAF) units, three hazardous waste storage tanks, and the furnaces’ associated hydrochloric acid recovery and air pollution control systems. The two HAF units are named the Symtet HAF (ST HAF) and the Manufacturing Services HAF (MS HAF). The ST HAF thermally treats chlorinated waste liquid and process vent feed streams, recovering the chloride as hydrochloric acid product. The MS HAF
thermally treats chlorinated liquid and process vent feeds, recovering the chloride as hydrochloric acid product. Both HAF units utilize computerized process controls to maintain continuous steady-state conditions. Two of the three storage tanks, T-501B and T-502A, store liquid hazardous waste feed material associated with the ST HAF. The maximum capacity of each tank is approximately 16,732 gallons. The tanks are located within the tank farm area associated with the ST HAF. The third storage tank, T-12, stores liquid hazardous waste associated with the MS HAF. The maximum capacity of T-12 is approximately 3,800 gallons. The renewed Hazardous Waste Facility Permit would allow the Facility to continue to operate the ST HAF and the MS HAF, the associated waste storage tanks, and associated process equipment.
There are no proposed changes beyond those authorized by the prior Permit and prior Permit modifications to the existing units and operations. This renewal extends the current Permit for ten additional years with no proposed physical or operational changes.
