Reclamation <br /> Early portions of the reclamation stage are estimated to begin late in year 1 and/or early in year 2 and will be <br /> completed concurrently with operations to reclaim previous years' mining operations as the site. Backfill <br /> material from the sand wash processing plant will be deposited behind the active mining area and used to <br /> regrade and contour each mining area for reclamation. Stockpiled backfill material from initial operations will <br /> be backfilled into the pit concurrently with active mining. Once each mining area has been graded and <br /> contoured to blend into the existing surrounding landscape,topsoil will be placed on the material and the area <br /> will be seeded with an approved native seed mix, as shown in Exhibit E. Please see the Reclamation Plan <br /> (Exhibit E) and Reclamation Map (Exhibit F)for more details. <br /> 6.4.4(f) Mining Details-The deposit to be mined is Eolian sand dunes that have been reworked by both alluvial <br /> and fluvial processes. Please refer to Exhibit C6.1—C6.2, Mining Plan Map,for estimated sand thickness <br /> contours across the project area. Relatively little topsoil and overburden are anticipated. Drill logs only show an <br /> average of approximately 2 feet of topsoil across all drill holes. <br /> Mining activities will occur above the water table.Sand resources located 2 feet above the water table or in the <br /> water table will not be disturbed. Reclamation activities will take place above the water table.See Exhibit C6.1 <br /> —C6.2, Mining Plan Map,for the estimated sand resource thickness contours. Drill logs indicate the presence of <br /> a predominately clay layer at the base of sands that is assumed to be low permeability. <br /> 6.4.4. (g) Commodities-The primary commodity to be extracted is industrial sand for use as a proppant in <br /> hydraulic fracturing. <br /> 6.4.4(h) Incidental Products-Currently no secondary products are planned or proposed for the operation.All <br /> mined materials unable to be sold as industrial proppant sand will be used as backfill material during <br /> concurrent reclamation. <br /> 6.4.4(i) Explosives/Blasting-The use of explosives in conjunction with construction,operations, or reclamation <br /> is not anticipated or proposed. <br /> 16 <br />
