Current Activities

Final Permit Issued: On Sept. 20, 2019, the department issued a final Missouri Hazardous Waste Management Facility Part I Permit to Exide Technologies Inc. for its Canon Hollow Recycling Center, effective Sept. 24, 2019. Any parties adversely affected or aggrieved by department’s decision to issue the final Part I Permit, or specific conditions of the final Part I Permit, may be entitled to pursue an appeal before the Administrative Hearing Commission by filing a written petition by Oct. 21, 2019, as more fully described on page 6 of the final Part I Permit.

Exide has been operating, performing long-term monitoring and maintenance of a closed landfill and conducting corrective action activities at the site under a department-issued Missouri Hazardous Waste Management Facility Part I Permit and EPA-issued Hazardous and Solid Waste Amendments Part II Permit. The status of Exide's post-closure and corrective action activities are described below.

On March 27, 2019, Exide submitted a permit application to the department and EPA, to renew the facility’s existing hazardous waste permits, which expire Sept. 23, 2019. After a thorough technical review of the permit application and opportunity for public comment on the draft permit, the department issued a final Part I Permit, effective Sept. 24, 2019. The final permit allows Exide to continue storing whole lead-acid batteries and hazardous waste in containers and containment buildings, treating hazardous waste in a stabilization unit, disposing smelter slag in an on-site hazardous waste landfill and monitoring and maintaining a closed landfill.

EPA decided not to issue a Part II Permit, since EPA has no site-specific conditions for the facility and Missouri is fully authorized for all permitting, post-closure, and corrective action activities at the facility. EPA will terminate the existing Part II Permit upon issuance of the Part I Permit.

The public can review and copy paper copies of the complete permit application, final Part I Permit, summary and response to comments and supporting documents at the Oregon Public Library, 103 S. Washington St., Oregon, Mo. (during normal business hours) or the agency locations above.

 

Exide Technologies is located on about 360 acres at 25102 Holt 250 Road, 4 miles northwest of Forest City. Exide operates a secondary lead smelting plant, known as the Exide Technologies Canon Hollow Recycling Center, which has been operating since at least 1975. Schuylkill Metals Corp., the original facility owners, became a division of Exide Corp. in 1996. In 2000, Exide Corp. changed its name to Exide Technologies.

Exide stores and recycles lead-acid batteries and other lead-bearing raw materials. The materials are classified as characteristic (D002, D004, D006, D008, D010 and D011) and listed hazardous wastes (K069). Exide disassembles the lead-acid batteries and separates the plastic case material, sulfuric acid and lead-bearing components. Exide ships the plastic case material off-site to a plastic recycler. Before 1983, the sulfuric battery acid went through neutralization and sedimentation in a series of concrete pits. The effluent, or wastewater, was then discharged into a series of four lagoons. In 1983, a wastewater treatment plant and an equalization lagoon were built and the four effluent lagoons were closed. The sulfuric battery acid is now collected, filtered and shipped off-site as product.

Exide uses four pot furnaces and a blast furnace to smelt the battery plates and other lead-bearing material into new metallic lead ingot. The final product, called secondary lead, is purchased by various manufacturers, re-melted and used in the production of new products. During the smelting process, impurities are removed from the lead as slag. Before 1981, the smelter slag was stored in three slag storage areas. The rubber chips from the broken battery cases were stockpiled in the rubber chip storage area. Both areas were closed in 1981. Exide currently treats the smelter slag and then disposes the non-hazardous slag in an on-site hazardous waste landfill. Landfill 1, which operated from 1981 to 1992, was used to dispose smelter slag, dewatered waste treatment sludge and rubber battery case chips.

Landfill 2, which began operating in 1991, currently is used to dispose treated air pollution control scrubber sludge, wastewater sludge and waste materials specified in Exide's Part A permit application. Landfill 2 has an overall design capacity of 754,000 cubic yards. Exide also operates three hazardous waste container storage areas, with a total maximum capacity of 1,182 cubic yards; eight hazardous waste containment buildings, with a total maximum capacity of 8,204 cubic yards; and one miscellaneous hazardous waste treatment unit, with a total maximum capacity of 12.5 tons/hour. The miscellaneous unit is a stabilization unit, which Exide uses to treat hazardous waste, air pollution control scrubber sludge and wastewater sludge.

The three slag storage areas and rubber chip storage area were closed in 1981. The rubber chips stockpile was removed from the rubber chip storage area and landfilled. The four effluent lagoons (surface impoundments) were closed in 1983. The contents of the lagoons were removed and treated in the wastewater treatment plant. The lagoons were then backfilled and asphalt-capped or reseeded.

Exide closed Landfill 1 in 1992. The department accepted Exide’s closure report and certification; however, because hazardous waste remained in place after closure, the area is also required to go through a period of post-closure care. As part of the post-closure care, Exide is required to monitor and maintain the final cap and groundwater monitoring system.

All hazardous waste treatment, storage and disposal facilities are also required to investigate and clean up hazardous waste releases at their facility resulting from present and past hazardous waste handling practices. Exide has removed and treated lead-contaminated soils near the active portion of the facility. Exide is investigating all property within the facility boundary to assess any potential releases. What, if any, corrective action, or cleanup, activities necessary will be based on the investigation results.

When EPA implemented the federal hazardous waste laws under the Resource Conservation and Recovery Act (RCRA) in 1980, all existing facilities that treated, stored or disposed of hazardous waste in a way that would require a hazardous waste permit were required to notify EPA and apply for the permit or close those operations. Because of the large number of existing facilities, Congress set up requirements which allowed these facilities to operate temporarily under “interim status” until they received their permit. Exide was granted interim status.

Exide currently is operating and conducting post-closure and corrective action activities at the site under a department-issued Missouri Hazardous Waste Management Facility Part I Permit, effective Sept. 24, 2019. The Part I Permit was originally issued with an EPA-issued Hazardous and Solid Waste Amendments Part II Permit in 1990, and reissued in 2009. EPA decided not to reissue the Part II Permit in 2019, since EPA had no site-specific conditions for the facility and Missouri is fully authorized for all permitting, post-closure and corrective action activities at the facility.

The Part I Permit allows Exide to store whole batteries and hazardous waste in containers and containment buildings, treat hazardous waste in the stabilization unit and dispose hazardous waste produced by Exide in an on-site landfill. The regulated units consist of three container storage areas, eight containment building areas, the stabilization unit and the on-site landfill. The permit also requires post-closure care of a closed landfill and corrective action in the event there is a release of hazardous waste or hazardous constituents to the environment.
