stockpiled from the excavation of Pond 013 will be used to construct the additional prime farmland attached to the undisturbed prime farmland area adjacent to Pond 013. The prime farmland area details on the WFC property are shown on Map 2.05.4 -6. The area of the topsoil replacement is shown on this Map and Map 2.05.4 -7 as well, where the area for the prime farmland replacement is shown as Zone 8 on Map. In order to restore this prime farmland, the following calculations and steps are provided: Step 1: Place 18 inches of Bench 1 subsoil substitute on 2.83 acres, which is then tested for suitability as subsoil under the same parameters as the Bench 1 Subsoil Substitute on the Morgan property, according to Table 2.05.4(2)(d) -1A. This is a volume of 6,848 cy. This material will be live hauled from the last 3 cuts of mining on the WFC property. Step 2: Place the stockpiled 14,730 cy of mixed Lift A and Lift B topsoil from Stockpiles #3 and #4 on the 2.83 acre area. This will allow a mixed topsoil thickness of 38 inches over this area. This combined with the 18 inches of Bench 1 Subsoil Substitute results in a total thickness of 56 inches. This Bench 1 material will be obtained from the mining of the last 3 mining cuts on the WFC property. The adjacent 1.13 acres will have undisturbed prime farmland soil (once Stockpile #4 is removed). This area will require disking and replanting for rejuvenation. No additional stripping in the area of the 98A soil is planned for the remainder of the life of the mine. No more excavation will occur in the pond area, therefore, if this material is replaced in the area it was removed, the prime farmland soil handling requirements will have been met. The two stockpiles will need to be moved prior to reclamation of Pond 13. The piles will be moved to the backfilled area of the pit near the pond, as mining approaches. The soil will not be mixed with any other soil from the mining area. Revised PR 06 June 10 2.05.4(2)(d) -35
