Dewatering will be conducted throughout the mining operation's life. Following final topsoiling <br /> and revegetation, the pit pump will be removed. Area 1 will contain a lake at this point; Area 2 <br /> will be a backfilled rangeland lot. <br /> 2_1 Topsoil and Overburden Handling <br /> It is not anticipated that any topsoil will need to be imported for the reclamation process, even at <br /> the point of greatest disturbance. The creation of the lake in Area 1 will leave it with excess <br /> topsoil based on the NRCS soil data. Area 2 will take in Area 1 overburden and topsoil excess to <br /> reclaim to final grade. <br /> Topsoil and overburden stripped during mining will either be stored in the temporary stockpile <br /> area or will be directly placed as part of final reclamation. Topsoil and overburden will be <br /> maintained in separate stockpiles in the temporary stockpile area. Table E-2 outlines the topsoil <br /> and overburden material balance calculations during reclamation and during the greatest <br /> disturbance area scenario. Excess overburden or topsoil generated during mining will be placed <br /> in reclaimed areas or shipped offsite. Overburden will not be stripped from berm or road areas. <br /> Topsoil stripping and replacement volumes are based on a 12 inches depth of topsoil. <br /> Overburden stripping is based on six feet of overburden on site. <br /> Table E-2.
