Material to be blasted down from the west highwall into the pit may be sold and removed from the pit, <br /> or may be left as backfill in the bottom of the pit,to transition from highwall to floor. <br /> Backfilling waste rock on the floor and fines on the benches can be done at toe of slopes to flatten wall <br /> slopes and create gently sloping bench areas on the west highwall and pit floor. <br /> If the Pit Lake remains as a permanent feature, its total surface will be 0.7 acres or less. All margins of <br /> the final pond will have slopes that will comply with Rule 3.1.5(7). No swimming is planned for this <br /> pond. <br /> Topsoil or growth medium will be placed on upper benches on West highwall area. <br /> Slope reduction by drilling and blasting: 2,000 CY @ $2.00/CY. <br /> Pushing and rough grading shot rock: 1,000 CY @ $1.00/CY. <br /> Placing and spreading waste rock and fines on benches: 1,000 CY @ $1.00/CY <br /> Seeding benches and unmined margins: 2.1 ac @ $1,000/ac. <br /> MQEW-1 (East Highwall) <br /> Currently, overburden above the ore body has been stripped to expose the ore body, which will be <br /> mined in benches down to the pond level. Attaining final bench and wall slopes will be by mining the <br /> ore body down. The overburden slope in the upper portion of this area is at or near their final <br /> reclamation gradient, and no further reclamation earthwork on this part is contemplated. Final <br /> reclamation of the lower part of this area, by mining in benches, will not commence until mining in the <br /> West highwall area is completed. Reclamation will occur as mining proceeds. <br /> The plan is to start extraction by drilling and blasting from the top of the ore body (which is located <br /> halfway down the East highwall where the ore body has been exposed) advancing down to the pit floor, <br /> and create the walls and benches as mining progresses. Material removal will occur in response to <br /> demand. <br /> The same wall and bench configuration described above for the West Highwall will be used in this area. <br /> Backfilling on the floor and benches can be done at toe of slopes with waste rock and fines to flatten <br /> wall slopes and create gently sloping bench areas on the east highwall and pit floor. <br /> If the Pit Lake remains as a permanent feature, its total surface will be 0.7 acres or less (as stated under <br /> West highwall, above). <br /> Topsoil or growth medium will be placed on upper benches on East highwall area. <br /> Slope reduction by drilling and blasting: 1,700 CY @ $2.00/CY. <br /> Pushing and rough grading shot rock: 1,000 CY @ $1.00/CY. <br /> Placing and spreading waste rock and fines on benches: 1,000 CY @ $1.00/CY <br /> Seeding benches, overburden slope, and unmined margins: 1.6 ac @ $1,000/ac. <br /> IMC-1 Quarry <br /> This pre-law pit has not been mined under this permit, but has been backfilled as part of the final <br /> reclamation of the permit. Backfilling has been completed, and the area is ready for grading and final <br /> reclamation. <br /> Final grading: D8 or equiv., 6 hrs @ $100.00/hr. <br /> Seedbed prep: D8 w/ripper, 3 hrs @$100.00/hr. <br /> Seeding: 1.3 ac @ $1,000/ac. <br />
