IMC-2 Quarry <br /> Area has been a quarry but hasn't been mined in many years. Quarry walls are steep and will need to be <br /> reduced to gentle gradient, either through mining or simply highwall reduction. <br /> No reclamation has occurred in this area. <br /> Slope reduction: blasting and grading with D8 or equiv.,4,000 CY @ $1.00/CY. <br /> Slope finish grading:4 hrs @ $100.00/hr. <br /> Pit floor grading: 2 hrs @ $100.00/hr. <br /> Seedbed prep (all areas): spread medium and rip, D8 or equiv. w/ripper, 3 hrs @ $100.00/hr. <br /> Seeding(all areas): 2.5 acres @ $1,000/ac. <br /> IMC-3 Quarry <br /> Area is currently being backfilled as part of final reclamation. Backfilling is not complete; approximately <br /> 1,000 CY additional material is needed (available as it is generated onsite). <br /> Haul backfill material: Cat 830 loader, 12-yd dump truck, 6 hrs @ $150/hr. <br /> Spread material: D8 or equiv., 2 hrs @ $100.00/hr. <br /> Finish grading and seedbed prep: D8 or equiv.w/ripper,4 hrs @ $100.00/hr. <br /> Seeding: 1.0 ac @$1,000/ac. <br /> MQD-1 Dump (West Dump) <br /> After all stockpiled crusher fines have been removed from this area (and placed in other areas for final <br /> reclamation),final reclamation will begin. Slopes are currently approximately 2:1, but are ready to be <br /> graded to 2.5:1. Grading will be done on fill slopes on the west and south,and the native hillslope on <br /> the north. <br /> A small portion of the area must remain unreclaimed to allow continued access into the Mica Pit. After <br /> the Mica Pit is reclaimed and equipment access is no longer needed, reclamation in this last part of the <br /> dump area may be completed. <br /> Most of the area's existing surface material to be graded consists of satisfactory growth medium. It is <br /> estimated that about one acre will require growth medium to be hauled in and spread. <br /> The Road 38313, along the south edge, is permanent and will remain after reclamation. <br /> Slope reduction: D8 or equiv., 3,500 CY @ $1.00/CY. <br /> Haul growth medium:Cat 830 loader and 12-CY dump truck, 1,000 CY @ $1.50/CY. <br /> Spread growth medium: D8 or equiv., 6 hrs @ $100.00/hr. <br /> Finish grading: D8 or equiv., 8 hrs @ $100.00/hr. <br /> Seedbed prep: D8 w/ripper, 6 hrs @ $100.00/hr. <br /> Seeding: 6.0 ac @ $1,000/ac. <br /> MQHW-1 (West Hiehwall) <br /> The highwalls on the southwest,west, and northwest sides of the pit are presently configured in rough <br /> walls and benches, by drilling and blasting. Further drilling and blasting and extraction will be required <br /> to attain final configuration, since the highwall overall is presently steeper than the final reclamation <br /> gradient. <br /> Final slope configuration (for stability and MSHA requirements)will be 40-foot tall walls at 1.25H:1V, <br /> alternating with 25-foot wide,gently-sloping benches. It will take a number of years to fully complete <br /> this highwall, since it is mined only in response to demand. <br />
