Revegetation at the initiation of mine development will be carried out on the upper overburden slopes <br /> and new earthen stormwater structures. Revegetation needed at the conclusion of mining will be <br /> limited to pit benches, pit floor, pad areas,onsite roads,and footprints of the last temporary stockpile <br /> areas for overburden and topsoil. <br /> The earthen stormwater berms, sediment ponds, and drainage structures will be permanent and will not <br /> require earthmoving during final reclamation. They will be seeded during the early development stage <br /> of the expansion. <br /> Onsite roadways will not require earthmoving, regrading, or topsoil replacement. They will be ripped <br /> and seeded for reclamation, in the final stages of site reclamation. <br /> Reclamation Costs: Equipment and Acreages <br /> Reclamation equipment likely to be used: <br /> Cat D8T Dozer(or similar)with semi-universal blade and 3-shank ripper <br /> Cat 950M Loader(or similar) <br /> Dump trucks, 10cuyd <br /> Elevating scrapers <br /> Skidsteer w bucket <br /> Ag tractor, 15HP,with disc; drill seeder <br /> 4x4 ATV with broadcast seeder; mesh drag,weed spray attachment <br /> Equipment to be mobilized from Salida, 50 miles away,avg speed 40 mph. <br /> Areas to reclaim To-do Acres x Depth ft=Vol CY Haul distance <br /> Pit floor, per Segment Backfill overburden 1.9 x 30=91,960 CY 2300 ft <br /> Pit floor, entire Grade,topsoil, reveg 5.7 x 0.5=4598 CY 1700 ft <br /> Pit benches,entire O/B and T/S, reveg 2.3 ac <br /> Operations Pad Grade, rip,topsoil, reveg 1.6 ac <br /> Processing Pad Grade, rip,topsoil, reveg 1.1 ac <br /> Topsoil stockpile area Grade, rip, reveg 1.3 ac <br /> Overburden stockpile Grade, rip,topsoil, reveg 2.8 ac <br /> Pit drainage channel Excavate,grade, riprap, reveg 280'x(78'x13')/2=5200 CY <br /> Onsite roads(temp.)
