Operator's Outline <br />• C. Creation and Reclamation of individual benches: Sequence to be performed in <br />creating a bench that can be reclaimed according to the plan. <br />1. Prior to trimming the bench to the final width as designed by the Bench <br />Geometry Model, the bench must be backfilled with limestone waste to <br />a slope of 3:1. <br />2. Topsoil is then placed on the backfill slope. <br />a. Soil depth should be a minimum of 6" where only grasses and <br />legumes are to be planted. <br />b. Where trees are to be planted (most benches) the soil depth <br />should not be less than one foot. <br />c. Woody material (branches, logs, etc.) should be left in the soil, <br />but do not count in the thickness requirement. The thickness <br />requtrement is for actual soil material, exclusive of woody <br />material. <br />3. Trim the bench to the final width (tce of the backfilled area). Do not <br />trim back into the backfilled area. <br />4. If funds are available for rock staining (an Enhanced Reclamation <br />action) then stain the backwall before revegetation. <br />5. Revegetate according to the Reclamation Plan. <br />VII. Area H (Hole) Mining <br />• A. Sequence <br />1. l~ttly limited mining should be done in Area H before Areas MV and <br />MS are completed. The intent of the plan is to complete the most <br />visible mining first and then mine the Hole at the base of the backslope. <br />2. Mining should proceed basically from north to south. Mining should <br />proceed downward until either the Saguache Sandstone is encountered <br />or the bottom of the hole becomes too narrow to go any deeper. <br />3. To maximize the depth of extraction, the maximum width at the top of <br />the Hole should be established early in the process followed by working <br />downward into the deposit. <br />B. Backfilling <br />1. The entire Hole must be backfilled to the elevations shown on the <br />Reclamation Plan Map. <br />2. The width of the Hole along anorth-south line should be kept as <br />narrow as possible by backfilling behind the mining area. By backfilling <br />closely behind the mining the amount of waste that must be stored to <br />fill the mining area can be limited which reduces the bond amount <br />required by the law. <br />3. The backfilling should be done, as much as possible, along an angle <br />with the leading edge of the backfill closest to the mining front and <br />along the west side of the hole. This will help limit the amount of <br />quarry backwall that is unsupported by either rock yet to be mined or <br />backtill. <br />Pikeview Quarry Amendment Page 3 <br />
