Exide is currently submitting a Hazardous Waste Facility Permit Application for its hazardous waste operations including treatment and storage activities at its plant located in 2700 South Indiana Avenue, Vernon, California.
Since 1992, Exide has recovered lead from various used, old or discarded materials. As a result, Exide was required to obtain a hazardous waste facility permit. Exide filed a Resource Conservation and Recovery Act (RCRA) Part A Application on August 8, 1980 for the hazardous waste storage and treatment activities. Exide has been operating the hazardous waste treatment and storage activities under an Interim Status Document which was granted to them on December 12, 1981.
On November 8, 1988, Exide submitted a Hazardous Waste Permit Application (Application) to DTSC. .After several years of dealing with the Application, DTSC then public noticed a draft Hazardous Waste Facility Permit (Permit), a Health Risk Assessment (HRA) and an Environmental Impact Report (EIR) on July 7, 2006. DTSC received numerous comments on the draft Permit, HRA and EIR.
Based on significant public inquiry and new regulations, significant upgrades were initiated at Exide under the joint oversight of the South Coast Air Quality Management District (SCAQMD) and DTSC. Exide has submitted a new permit application to DTSC which is currently under review by DTSC. The permit application includes the following operations:
Battery and Material Receiving
All batteries and other materials are delivered to Exide by trucks. The authorized hazardous waste codes for accepting are D002, D004, D005, D006, D007, D008, D010, K069, CA132, CA171, CA172, CA181, CA352, CA724, and CA792. Inspection of hazardous wastes received is completed in two stages. The first stage is at the receiving scale where loads arriving at the receiving scale are compared to the shipping papers or manifests. For batteries, variations in weight or deviations in pallet count are reconciled by phone with the generator. At the stage two, the hazardous wastes is then placed in containers and stored in the designated container storage areas prior to processing.
Hazardous Waste Storage
Exide stores the hazardous wastes in three receiving buildings before processing.
Hazardous Waste Treatment
Raw Material Preparation System
The Raw Material Preparation System (RMPS) is the process through which the used batteries are cut in smaller pieces, and the liquid acid is drained. Subsequently, the solid waste materials are passed through a series of screens and separation processes to additionally separate liquid acid, lead sulfate paste, metallic lead, rubber, and plastic separator fluff. Currently, the RMPS process consists of fourteen tanks and seven miscellaneous units.
Wastewater Treatment System
Wastewater generated by Exide as a result of draining liquid from used batteries is treated onsite by a wastewater treatment (WWT) system to remove the solid and dissolved metal from the stream prior to being discharged to the industrial sewer. All wastewater discharges are tested daily for compliance with the permit requirements established by the Los Angeles County Sanitation Districts. The wastewater treatment system consists of 19 tanks.
Furnace Feed Material Storage Building
The furnace feed materials are either generated by the facility or received from offsite generators. The furnace feed materials are stored in a containment building before feeding to the furnaces..
Reverb and Blast Furnaces
Two furnaces are used to smelt and recover lead. A rotary kiln is used to reduce the moisture prior to the material entering the Reverb Furnaces.
Baghouse Dust Slurry Tanks
Two slurry tanks are used to collect baghouse dust from screw conveyors at the base of each baghouse.
Two oxidation tanks are used to neutralize sulfuric acid liquor from the SO2 scrubber.
Mobile Equipment Wash Area
As part of normal facility operations, a Mobile Equipment Wash Station is used to clean vehicles and other facility equipment. The wash water and solids collected in the Wash Area Sump are pumped to the Battery Dump Bin Sump.
The Drop-Out System is used to remove the solids from the storm water and other areas prior to discharge to the Wastewater Treatment Plant. The system consists of five above-ground tanks.
The facility is proposing to modify an existing retention pond to meet the regulatory requirements for a surface impoundments specified in California Code of Regulation, title 22, chapter 14, article 11. Water collected in the Retention Pond will be pumped to the Drop-out system and then treated by the Wastewater Treatment Plant.
