As soon as practical after topsoil is no longer being moved to or moved from a stockpile, WFC will seed the pile with Seedmix #3 as presented in Section 2.05.4(2)(e). A topsoil sign will be placed at the toe of the pile as required by rule. Topsoil stockpile locations are shown on Map 2.05.4(2)(d)-2. Topsoil Replacement Topsoil will be replaced only when the approved post mine topography (PMT) has been achieved. Topsoil will not be replaced on temporary reclamation sites such as haul road ditches, cut, slopes and fill slopes, pond embankments and spillways, and diversion ditches. Topsoil shall be replaced along the contour, whenever feasible, to minimize potential erosion and interface slippage problems. This practice will be discontinued on steep slopes (>20%) where the safety of the equipment operator is in jeopardy. Topsoil will be scarified on the contour to a depth up to 24 inches with a chisel plow or ripper. The operation of seed bed preparation will also reduce compaction, increase infiltration, and promote surface roughness. Whenever practical, the salvaged topsoil will be immediately transported to graded Bench 1 areas and placed on top of the Bench 1. The direct haul method is economically desirable and also maintains a high topsoil quality by a direct transfer of viable seed microbes, and roots; reduced compaction, better preserved structure, increased aeration and stable nutrient status. Topsoil will not be handled when saturated either during the initial stripping, spreading or final grading. Specific protective measures will be utilized to minimize wind and water erosion. Such measures will include contour ripping or chisel plowing of graded replaced topsoil and rapid establishment of vegetation. Long unbroken slopes will be avoided to minimize sediment runoff and gullying. Map 2.05.4(2)(d)-1 denotes the anticipated thickness of the topsoil replacement.
