• <br />• <br />Memo to Planning Commission <br />April 17, 1995 <br />Number of Animals <br />Page 3 <br />With the proposed updating of the swine buildings, Cargill is also proposing <br />to decrease the overall number of pigs kept at the facility. The following <br />table highlights the proposed changes. <br />Breeding animal inventory <br />Current Proposed <br />225 180 <br />Feeder pigs per year (those under 50#) <br />-Approx. one time capacity <br />Finishing pigs per year (50-250#) <br />-Approx. one time capacity <br />3,000 3,600 <br />550 600 <br />2,500 1,650 <br />800 575 <br />Due to the proposed changes, Cargill is also required to upgrade their <br />existing feedlot permit from the Minnesota Pollution Control Agency. Cargill <br />has already received approval of the upgraded feedlot permit from the <br />Minnesota Pollution Control Agency. Through the permit the MPCA does set <br />conditions on the application rate of manure to the surrounding property and <br />for general environmental conditions such as release to public waters, etc. <br />Waste Management <br />In conjunction with the improved swine facilities, Cargill is also proposing to <br />upgrade their waste management system. Currently, manure is handled <br />through three systems. Approximately 25% of waste is handled as a solid <br />and is spread on the fields weekly. Approximately 25% of the waste is <br />handled as a liquid pumped from pits under some of the swine buildings. The <br />remainder is handled as a liquid drained from the buildings to three lined <br />earthen basins. <br />The proposed system would enable all the manure to be handled as liquid <br />through the earthen basins. The upgrade would reduce the frequency of land <br />spreading, thus, better odor control with less agitating of the waste. Earthen <br />basins also allow for better timing of when to spread the liquid waste, thus <br />eliminating spreading of any swine waste on frozen ground. Rainwater <br />caught in the basins would also assist in dilution of waste, further reducing <br />the odor potential. Due to the fact that the number of swine will actually be <br />decreasing with this proposal, staff feels comfortable that the proposed <br />earthen basin upgrade will be sufficient to handle the manure load. <br />cu95-05-planning/pc <br />
