Soil piles stored in WMU G shall at all times be completely covered <br />with a synthetic liner, except during aeration. <br />43. Soils containing contaminants other than petroleum hydrocarbons and <br />BTX (for example, chlorinated hydrocarbons, heavy metals, etc.) shall <br />not be placed in WMU G without prior approval of the Board. <br />44. WMU G shall be graded so that runoff will collect in a sedimentation <br />pond dedicated to that unit. Water leaving that sedimentation pond <br />may be discharged if it does not contain waste. <br />DRYING OPERATION SPECIFICATIONS <br />45. Food processing wastes may be disposed of by spreading on a one foot <br />thick, compacted clay pad that is bermed to prevent runoff. Within <br />48 hours, this waste shall be disced into the clay pad in such a <br />manner as to allow drying of the waste with no percolation of liquid <br />through the bottom of the clay pad. Once the waste has dried, it <br />and any soil it has contacted shall be moved to WMU D, or WMU H for <br />disposal. The clay pad shall be rebuilt to its original thickness <br />after each drying cycle. The application rate of food processing <br />waste shall not exceed 270 cubic yards per acre. This operation may <br />be done from May through October. <br />
