Response: Since the mining operations will generally be a truck and shovel operation, the slopes during mining will be .SH: l V. As we approach the perimeter of the borrow pit, we will mine at a 3H:1 V slope to eliminate the need to backfill the highwalls. Exhibit D — Reclamation Plan (Rule 6.3.4): 7) Under section (1)(b), the applicant proposed final reclaimed slopes of'3H. I V If the pit walls will be backfilled to achieve the fina13H. I V slopes, please describe whether this will be done by backfilling with additional material or via the cut and fill method. If the applicant proposed backfilling slopes with additional material please describe the source for this material and an estimated volume required. If the applicant proposes backfilling slopes via the cut and fill method, please explain how the operation will complete this task given the close proximity of the pit edges to the proposed permit boundary (as shown on the mining and reclamation maps submitted). Response: Since the mining operations will generally be a truck and shovel operation, the slopes during mining will be .SH: I V. As we approach the perimeter of the borrow pit, we will mine at a 3H:1 V slope to eliminate the need to backfill the highwalls. 8) Will the operation maintain a setback f om the permit boundary to allow room. for reclamation of'pit slopes? If so please specify the proposed setback and be sure to shoo, the setback on the mining and reclamation plan maps submitted. Response: Although not shown on the mining and reclamation plan maps due to scale, we will maintain a two to three foot offset from the permit boundary. This will allow ample room to place plant growth material on the final pit slopes and perform seedbed preparation and final seeding. Since the final pit slope will be mined at 3H:I V, there will be no need to have heavy earth moving equipment on the 3H: I V final slopes to place backfill. Topsoil maybe placed midway on the slopes undergoing reclamation by pushing uphill and back dragging the topsoil downhill. All final reclamation operations (Seedbed preparation, fertilizer application and seeding) will be on the contour as long as it can be done without endangering the reclamation equipment and equipment operator. 9) Under section (2), the applicant proposes a reclamation bond in the amount of 567,375.00 ($2,500 per acre for a total of 26.95 acres). Pursuant to rule 4.2.4(1), the financial warranty for a 111 Special Operation Permit shall be in the amount of not less than $2,500.00 per acre of affected land. However, the Division may require such other greater amount necessary to ensure that estimated costs of reclamation are assured. In this case, the Division has identified adequacy items above regarding the proposed pit depth, importation of topsoil, and potential importation of backfill material that,
