filtration and sludge thickening processes. Cyanide destruction will be accomplished with a cyanide oxidation process. After metal removal, wastewater from these processes will be treated further by clarification, neutralization, and multi -media or sand filtration, and discharged to the sewer. Precipitated metal hydroxides will be dewatered and processed for recovery and resale if they have any economic value, or ' they will be shipped to permanent landfill storage out- of-state. It is expected that 10% to 15% 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 metal waste. Wastes which are not amenable to recovery will be processed into inert solid residuals as neutralized mixed metal, dewatered hydroxide sludges. Solid detoxified (nonhazardous) inert substances generated during processing will be disposed at sanitary landfills in Minnesota. Mixed metal sludges and organic materials will oe transported from the Facility and disposed or subjected to additional processing at approved out-of-state hazardous waste facilities. 2.20 Operations and Process. The Facility will be p Y operated by CECOS International, Inc., pursuant to an operations agreement with the Metropolitan Recovery Corporation. CECOS owns and operates eight hazardous waste processing and disposal facilities in the United States. 2.21 Hours of Operation. The Facility will operate on shifts Monday through Friday from 7:00 a.m. to 6:00 p.m. The Facility entrance gate will be opened at 6:30 a.m. and close at 6:30 p.m. The Facility will operate as a secure Facility with a separate door entrance for normal administrative and business customers coming from the parking lot. There will be no entry to the process area without screened access through truck delivery or through the administrative or laboratory office area. 2.22 Waste Pickup. All incoming wastes will be governed by contracts between waste generators and the Facility operator with prearranged volumes and material characteristics specified in these agreements. A customer pickup and acceptance routing will be prepared on a monthly basis based upon the volumes and frequencies of pickup material being generated by customers. Any example of customer bad practice in labelling or containerizing materials will result in a breach of the customer agreement with corrective action being taken immediately. Processing agreements will be 4.
