3.1.5 Reclamation Measures -Material handling <br />(1) Grading shall be carried on so as to create a final topography appropriate to the frnal <br />land use selected in the Reclamation Plan. <br />(2) When backfilling of the excavated area will consist of overburden andlor any inert <br />materials which may be hauled in from off site. Additionally all backfitl material will be <br />compacted in place to insure stability. Notoxic oracid-forming materials will be on site nor <br />will any be delivered to this mine site. <br />(3) All grading shall be done in a manner to control erosion and siltation of affected lands. <br />Best Management practices of mining will be used to protect areas outside the affected <br />land from slides and other damage. No highwalls are planned at this open pit mine. <br />(4) All backfilling and grading will be completed as soon as feasible after the mining <br />process. The operator will establish reasonable timetables consistent with good mining <br />and reclamation procedures. Grading of backslopes will be as mining is occurring, and the <br />pit floor will be contoured for seeding as mining proceeds. <br />Topsoiling will be accomplished after mining has moved away far enough to make it <br />practical for seedbed prep and seeding. Also, time of year and weather conditions will play <br />a role in this timing. <br />(5) No refuse will be generated by this mining operation for cleaning and preparation of <br />substances mined. No acid-forming or toxic-producing materials will be mined or used for <br />processing at this sand and gravel mining -processing plant. Therefore, no plans have <br />been developed for their handling. <br />(8) There will not be any drill or auger holes unfilled after mining. All exploration will most <br />likely be done with small bore coring by a trained crew or by backhoe in selected areas, <br />and after discovery, all holes shall be backfilled as soon as possible. No adits or shafts will <br />be employed in this open pit. <br />(7) Maximum slopes and slope combinations shall be compatible with the configuration of <br />the surrounding conditions and selected land use. Where the pit does not daylight, <br />backsloping during mining will be completed at a slope of 3H:1V or flatter. No lakes or <br />ponds are designed for the final reclamation, which is rangeland. Therefore, no swimming <br />areas are proposed. <br />(8) The Operator's/Applicant's and Landowners' choice of rangeland reclamation for cattle <br />production will require slopes of 3H:1V or flatter in order to establish good cattle grazing <br />areas, and to prevent erosion. Farm machinery will be. used only at the time of <br />revegetation and will not be a factor long range. <br />
