this topsoil (4,200 cy) will be placed in a stockpiles east of the water treatment area (Topsoil <br />Stockpiles #2 and #2A) and the subsoil stockpile (see Sediment Pond Excavation below). Some of the <br />topsoil (200 cy) will be placed as a 6-inch cover over the sideslopes of the sediment pond and the fill <br />stockpile that will be excavated from the pond area. The placed topsoil will seeded to produce a stable, <br />vegetated cover during active mining operations. During reclamation, the topsoil will be stripped from <br />the subsoil stockpile and the sedimentation pond prior to regrading the area. After the area has been <br />regraded to the approximate original contours, the topsoil will be placed on top. <br />The total estimated volume of topsoil available from the four areas is approximately 30,400 cubic <br />yards. It is believed that this estimated volume is accurate to plus or minus 20 percent. The reclamation <br />design and cost estimate are based salvaging and placing 30,400 cubic yards of topsoil. <br />A summary of the topsoil stockpile areas is given below: <br />Stockpile #1: Main Stockpile located north of County Road containing 5,900 cy from the initial <br />• stripping of Area 2 plus 1,300 cy from Area 1 for a total estimated volume of 7,200 cy. The <br />stockpile area shown on Map C-2 is larger than necessary to store 7,200 cy, so there is extra <br />storage space available in case the average stripping depth is greater. <br />2. Stockpiles #2 and #2A: Located at Water Treatment Area with an estimated volume of 4,200 <br />cy. <br />Stockpile #3: Temporary stockpile located at Whirlwind portal bench with an estimated volume <br />of 3,900 cy. <br />Total estimated topsoil storage required: 15,300 cy <br />Temporary topsoil stockpiles will be created in front (i.e., east) of the waste rock pile as it expands. <br />This material will be used to concurrently reclaim the north facing waste rock pile slopes next to <br />County Road 5/10 after they are regraded to a 3H:1V configuration. <br />Each topsoil stockpile will have a small, one-foot high berm along the perimeter to isolate it from the <br />• surrounding area runoff and to trap runoff from the stockpile itself within the ditch created by the <br />Whirlwind Mine 07 (rev. April 08) D-19 <br />
