The facility will be operated as a Minnesota corporation. The 28 participating metal waste generators own stock and ��. will have rights regarding the facility's operation. The facility will consist of a 60,000 square foot building which will house processing equipment including separators, vats, and tanks to extract metals from the waste received from metal finishers. Specially designed trucks, semis and tank trucks, will transport waste material from the metal finishers to the facility. Metils will be recovered at the facility from inorganic solutions, sludges, and ion exchange canisters picked up at meta]. finishing plants. Bulk shipments of relatively concentrated solutions will be processed to extract metals and metal precipitates. Certain metals sludges will be accepted for further dewatering and processing. Processes to be used at the facility to remove metals from the incoming waste feed stock will include ion exchange, activated carbon adsorption, chromium reduction, electro- chemical recovery, metal precipitation, acid and base neutralization, filtration, and sludge thickening processes. Cyanide removal will be accooplished with a cyanide oxidation process. After metals removal, waste- water from these processes will be treated further by clarification and neutralization, and multimedia or sand filtration. (Refer to Attachment 6 for a detailed process descr4-t4on.) Precipitated metal hydroxides will be dewatered and processed for recovery and resale. It is expected that 10% to 25%. by dry metal weight, of the incoming metal waste will be recovered for reuse. Nonhazardous waste, primarily zinc, will constitute approximately 30%, by dry metal weight, of the incoming processed wastes. Approximately 75% of the total incoming wastes will not initially be amenable to recovery. These will be processed into inert solid residuals, mixed metal, dewatered sludges, or neutralized. Solid inert substances generated, if nonhazardous, will be disposed of at sanitary landfills in Minnesota. Mixed metal sludges and organic materials will be disposed of at approved out-of-state hazardous waste facilities, or at approved solvent and oil recovery facilities. 6. Reason for EAW preparation: Mandatory Category MEQB Rule #: 6 MCAR § 3.038.0.2 requires MPCA to prepare an EAW for construction of a hazardous waste processing facility which sells processing services to generators other than the owner and operator of the facility, of 1,000 or more kilograms per month capacity. 7. Estimated construction cost: $5,000,000 3.
