be as deep as 38 feet (5, 570 feet elevation S, 532 feet elevation), and the <br />northern pit area may also be as deep as 38 feet (5,580 feet elevation - 5,542 feet <br />elevation). Please explain and.: or correct this discrepancy. <br />Response: <br />You are correct in your statement of the maximum depth. We were attempting to give an <br />approximate average maximum depth given the variability in the proposed depth of <br />mining. <br />6) Please specify the proposed mining slope for pit walls. <br />Response: <br />Since the mining operations will generally be a truck and shovel operation, the slopes <br />during mining will be .5H:1 V. As we approach the perimeter of the borrow pit, we will <br />mine at a 311:1 V slope to eliminate the need to backfill the highwalls. <br />Exhibit D — Reclamation Plan (Rule 6.3.4): <br />7) Under section (1)(b), the applicant proposed final reclaimed slopes of 3H.1 V. If <br />the pit walls will be backfilled to achieve the fina13H.1 V slopes, please describe <br />whether this will be done by backfilling with additional material or via the cut <br />and fill method. If the applicant proposed backfilling slopes with additional <br />material please describe the source for this material and an estimated volume <br />required. If the applicant proposes backfilling slopes via the cut and fill method, <br />please explain how the operation will complete this task given the close proximity <br />of the pit edges to the proposed permit boundary (as shown on the mining and <br />reclamation maps submitted). <br />Response: <br />Since the mining operations will generally be a truck and shovel operation, the slopes <br />during mining will be .5H:1 V. As we approach the perimeter of the borrow pit, we will <br />mine at a 3H:1 V slope to eliminate the need to backfill the highwalls. <br />8) Will the operation maintain a setbackfi•om the permit boundary to allow room for <br />reclamation of pit slopes? If so please specify the proposed setback and be sure <br />to show the setback on the mining and reclamation plan maps submitted. <br />Response: <br />Although not shown on the mining and reclamation plan maps due to scale, we will <br />maintain a two to three foot offset from the permit boundary. This will allow ample <br />
