Coal <br />stockpile areas will be constructed to provide effective drainage of both runoff from stockpile <br />surfaces and infiltration through the stockpiles. Designed ditches will collect and route surface <br />runoff from coal stockpile areas to designed sedimentation ponds. The locations of the designed <br />ditches and sedimentation ponds are shown on Map 2.05.3 -M4, Drainage and Sediment Control <br />Plan. and detailed design calculations are presented in Exhibit 2.05.3 -E2, Drainage and Sediment <br />Control Plan. <br />Surface runoff from the overburden fill area (developed as the coal stockpile /facilities pad) will be <br />controlled by site grading, localized drainage control measures, and by collection ditches. <br />Upgradient drainage will be diverted around the stockpile areas. Ditches will collect and route <br />surface runoff from the pile areas to sedimentation ponds for settlement of suspended solids and <br />treatment if necessary. The locations of the ditches and sedimentation ponds are shown on Map <br />2.05.3 -M4, Drainage and Sediment Control Plan, and detailed design calculations are presented in <br />Exhibit 2.05.3 -E2, Drainage and Sediment Control Plan. Operation of sedimentation ponds under <br />PSCM's pending CDPS permit will assure compliance with applicable water quality regulations and <br />effectively mitigate any potential surface water quality impacts. The initial step in reclamation of <br />the coal stockpile will involve removal of any remaining stockpiled coal materials and associated <br />Midterm Review 2.05-17 Revision 04/2013 <br />
