A small stockpile of Lift A material will remain after final backfilling and filling to reclaim Pond 011, as shown on Map 2.05.4 -6. This is Stockpile #18, which will contain approximately 7,250 cy. Lift B Topsoil Lift B: 29.3 acres - 3.19 acres (pond 011) + 1.72 acres additional area on east edge of stripping area = 27.83 acres. The remaining Lift B Topsoil to be stripped in front of the June 2010 active pit = 27.83 acres x 46 inch average thickness = 172,113 cy. The total Lift B available is 172,113 cy (from new stripping) + 221,516 cy from Stockpile #12 = 393,629 cy. Lift B Topsoil in front of the June 2010 active pit will be combined with stockpiled Lift B Topsoil to provide 33 inches thickness over Zones #3 and #4. Table 2.05.4(2)(d) -2A shows that this required volume is 381,598 cy and the available volume of 393,629 is more than adequate. All topsoil salvaged will be placed, therefore, if 393,629 cy is available, the final thickness of Lift B over the area will be slightly greater than 33 inches. Stockpile #15 will also be created from final cut stripping, which will be approximately 191,840 cy which will be used to reclaim Zone #4. A small stockpile of Lift B material will remain after final backfilling and filling to reclaim Pond 011, as shown on Map 2.05.4 -6. This is Stockpile #17, which will contain approximately 8,860 cy. Mixed Topsoil The total mixed topsoil available for the property is 132,271 cy from Stockpiles #5 and #6, and 27,906 cy from the 17 inches thickness placed in Zone 1 (7.81 acres) = 160,177 cy. All the Mixed Topsoil will be spread evenly across the remaining disturbed areas (Zone 1 -3) that have had subsoil placed, but still require topsoil. Calculations showed that the Mixed Topsoil will be spread at an average 21 inch thick over Zones 1 through 3 (51.73 acres). The required amount to do this is 150,309 cy. Therefore, the volume of 160,177 cy is more than adequate. Revised September 2010 (PR 06) 2.05.4(2)(d) -32
