, -2- After several months, it is expected that much of the initial oxygen demand will be exerted and the volume of the yard waste will be reduced to approximately one-half of its initial volume. In order to maintain aerobic conditions and to optimize the composting process, the windrows will be turned several times per year. After one year of composting, the composted material will be removed from the site to make room for the next season's yard waste. The finished compost will be made available to the public free of charge with remaining amounts used as a mulch and as a soil additive at Lake Farm County Park. 2.3 Site Size The prposed Lake Farm compost site will occupy four acres. Its expected capacity will be 20,000 cubic yards. 2.4 Present Land Use The site is located on land that is owned by the Dane County Park Commission. The land is reserved for long-term development as part of Lake Farm Park. No scheduled park use is planned for the next 10-15 years. Lake Farm Park also consists of land located north and east of the proposed compost site. The remaining land in the area is primarily agricultural. A small residential development is located to the west along Libby Road. The agricultural land to the south of Libby Road is the site of the proposed Libby/DeBeck landfill. These current and proposed land uses are unlikely to be affected by the proposed yard waste composting operation. The prcpaeed compost facility meets the location and performance standards as specified in NR 502.02(2) and NR 502.04(3) Wisconsin Administrative Code with the exxception of seven private wells that are within 1200 feet of the site. These wells range from 200 to 1100 feet from the proposed compost site. A setback exemption is requested for these wells. Proper grading of the site and the permeable base should result in the production of only small amounts of runoff. The nature of the materials being composted and the fact that moisture will likely need to be added to maintain optimum moisture levels make the chance of adverse environmental effects unlikely. 2.5 Potential Markets for the Compost The public will be allowed to pick up the finished compost at the site free of charge. The remaining compost will be used as a mulch and to augment topsoil supplies at Lake Farm County Park. 2.6 Waste Disposal All of the composted material will be given away or used at Lake Farm County Park as described in the previous section. As a result, it is not expected that a surplus of composted material will be stored on site. If more composted material is produced than can be used at Lake Farm County Park, area farmers will be contacted to take the surplus. Composted yard waste will not be landfilled. Any trash mixed in with the yard waste will be removed and disposed of at Dane County Landfill Site No. 2.
