All areas where corn sileage is stockpiled must be covered with <br /> an impervious surface such as asphalt , concrete or compacted <br /> clay. The edges must be raised to catch the leachate, and the <br /> surface sloped to the collection system. <br /> 2. The leachate must be collected and temporarily stored in an <br /> impervious retention pond or tank. The system must be constructed <br /> in accordance with the recommendations of the USDA Soil Conservation <br /> Service and/or the Wisconsin Department of Natural Resources . <br /> 3 . The owner must remove the leachate from the retention pond frequently <br /> enough to prevent it from becoming anaerobic ( septic ) . The leachate <br /> must be spread and preferably knifed-in on agricultural land . The <br /> rate of the application shall be based on the nitrogen uptake of <br /> the crop to be grown per the analyses and recommendations of the <br /> Department of Natural Resources , Soil Conservation Service and/or <br /> UW - Extension. <br /> 4 . The leachate presently ponded in the low area east of the sileage <br /> storage site shall be removed as completely as possible and knifed- <br /> in as per item 3 above . <br />
