areas (refer to Exhibit D -1) within or adjacent to each 5 -Year production panel for re- application to the <br />mined area. Where appropriate, trucks may be utilized to supplement scraper excavation. <br />Wherever possible, topsoil and subsoil will be directly placed onto regraded overburden surfaces, via an <br />in -pit ramp from the pre -strip area to areas of active reclamation. An exception to this occurs in the area <br />of the central conveyor /access road /ditch corridor, which will remain open until completion of mining in <br />each panel. Each 1 -Year production block will be reclaimed by placing the overburden material on the pit <br />floor stripped from the adjacent panel subject to active quarrying and then reapplying the subsoil and <br />topsoil, except for the conveyor corridor, which will remain open until mining is completed in each panel. <br />Similarly, secondary access roadways along each side of the reclaimed spoils will be reclaimed following <br />the cessation of mining in each panel. <br />conveyor /face access road may be covered by stockpiles of shale /unconsolidated materials and /or <br />t, <br />mining each panel. Alternatively, material for reclamation of the Year 1 block may come from the <br />stockpile located up gradient of year 5.Refer to the generalized cross - sections A -A' through C -C' on <br />Exhibit D -1, which illustrate the position of in -pit reclamation backfill and the conveyor corridor slot <br />during active mining. <br />from the crusher and enclosed conveyor belt to plant. The actual thickness of the material to be removed <br />TOPSOIL & SUBSOIL SALVAGE <br />As discussed in more detail in Exhibit I — Soils Information, A and E- horizon topsoil materials will be <br />salvaged separately from AC or B- horizon subsoil materials. Topsoil and subsoil removal and <br />replacement operations may be conducted with any of several combinations of equipment including a <br />scraper, truck/shovel, truck/loader, backhoe, dozer, etc. Mobile equipment will be used to remove topsoil <br />and subsoil materials that will be either directly hauled from the pit in advance of reclamation or placed in <br />stockpile storage area shown on the mine plan, adjacent to each production panel for easy re- application <br />to the mined area. It is proposed that each production block will be fully reclaimed by placing the <br />overburden material from the adjacent panel on the floor of the pit and then reapplying the subsoil and <br />topsoil. Reclamation of active roadways along which conveyor belts are located, will be performed when <br />the conveyors and roadways are no longer required for mining activities and either relocated or <br />permanently removed. <br />GCC' is proposing two topsoil /subsoil removal options. The first option is utilized when topsoil and <br />subsoil materials are being directly hauled from the pit in advance of reclamation. The second option is <br />utilized when topsoil and subsoil materials are being stockpiled for later redistribution. The baseline Soil <br />Volume Summary contained in Exhibit I — Soils Information, contains a listing of soil types and <br />recommended salvage depths. The salvage depths are based on critical review of the soil laboratory <br />analyses contained in Appendix B - SOILS DOCUMENTATION, the baseline soil surveys and the <br />NRCS Soil Survey for Pueblo County (SCS, 1979). While these topsoil and subsoil salvage depths <br />average 6 and 12- inches respectively, soil salvage depths will be determined by actual soil depths that are <br />determined generally by topographic position. Deep topsoil is usually located in draws and valley floors <br />while ridge tops have generally very shallow topsoil. Shallow ridge topsoil usually covers unweathered <br />overburden that may not be favorable for final reclamation. <br />TR 4 with Markup <br />April 26, 2013 <br />D -5 <br />
