Case #5: WMMI C.U.P Request for Yard Waste Compost Facility Mr. Otto stated that Waste Management of Minnesota, Inc. is requesting a conditional use permit to operate a yard waste composting facility south of the existing landfill site. The size of the proposed facility is ,3,_00 tons (I 16,000 cubic yards). The facility woald be located on ~: acres. The Planning and Zoning Commission held a public hearing on February 6, 1990 and on September 4, 1990, the Planning and Zoning Commission recommended adoption of findings of facts and approval of the conditional use permit by a four to three vote. Mr. Otto stated that staff's greatest concern with the request focuses on production of odors at the facility and the proximity of the facility to residents in Hunter's Hill. Mr. Otto briefly reviewed the proposed findings of fact adopted by the Planning and Zoning Commission. Steve Kollodge of Waste Management was present and stated that the yard waste facility is proposed to be located on 33.4 acres of land west of Sunfish Lake Boulevard N.W. and south of the landfill. 14.5 acres would be utilized as a composting area, four acres would be used for curing area and one acre would be used for the tipping area. The remainder of the 33 acres would serve for drainage and buffer. The facility would accept leaves, grass and tree prunings. The operator will not accept bagged yard waste in plastic and the customer will be responsible for debagging the waste at the facility and containers will be provided for disposal of plastic bags. Mr. Kollodge noted that it appears that the plastic bag~ng is a major contributor to odor problems at yard waste facilities and the operator feels it would be in the best interest to require immediate debagging of materials. After materials are accepted at the tipping area, the operator will moisture condition it and transfer it into windrows in the composting area where it will stay for six to twelve months. During that time the yard waste will be monitored for oxygen ph, moisture content, appearance and odors. Following the composdng process, the material will be moved to the curing area where it ,MI1 rema/n for another six to twelve months. Following the cm'-ing time, the product will be finished compost and can be used for man)' different purposes. Mr. Kollodge noted the two greatest concerns from the community is odors and ground water contamination. Mr. Koliodge stated that the Found water in this area runs northwest to southwest across the composting facility. There are also monitoring wells already existing on the lanctfill propercy. If there were any ground water impact caused by composfing, the monitoring wells will detect a difference in *' ~ m~ water content. With respect to odo::q. Mr. Ko!tod~e stat~ that they are almost aiwavs associated with improper operation.
