2.05.4 <br />The drill pads for the Gob Ventilation Bore Holes will be reclaimed when the <br />GVBs are no longer required. If topsoil is not salvaged in adequate quantity <br />to provide a suitable seed bed, one will be developed as explained in the <br />paragraph above. Reclaimed light use roads and drill pads will be graded to <br />approximate original contour. <br />(2)(d) A plan for the removal and storage of topsoil is presented in Section <br />2.05.3(5). During reclamation operations topsoil will be placed on regraded <br />areas in an approximate uniform, stable thickness. Map No. 32, Topsoil <br />Distribution Plan, shows the location of the topsoil stockpiles and the areas <br />where and thickness which topsoil will be spread. <br />Topsoil stockpile A (previously A, B and C) contains 111,900 cubic yards and <br />will be spread over 64.0 acres which will provide an approximate uniform <br />stable thickness of over 12- inches. Topsoil stockpiles D & E contain 42,472 <br />cubic yards and will be spread over the 48.9 acre gob pile area which will <br />provide an average replacement depth of approximately 6- inches. Additional <br />topsoil will be salvaged from the gob pile founding which will supplement the <br />6 -inch topsoil replacement depth. The 12 -inch topsoil depth should provide <br />adequate depth for the establishment of a self- sustaining cover of grasses, <br />forbs and shrubs. The self- sustaining vegetation is appropriate for the <br />postmining land use of rangeland and wildlife habitat. The 6 -inch depth for <br />the gob pile area is marginal, however the actual replacement depth in this <br />area will increase as additional topsoil is salvaged. <br />Topsoil stockpile F will contain 24,000 cubic yards. It will be spread over the <br />22 acres of the reclaimed unit train loadout to a depth of approximately 1.2 <br />feet. <br />The regraded and topsoiled surface will reestablish the surface water <br />drainage system by returning the area to the approximate original contours. <br />The regraded surfaces will be ripped if necessary to relieve compaction and <br />to provide for root penetration. Topsoil will be placed and spread with either <br />scrapers or a front end loader and truck equipment spread. The topsoil will <br />be spread with a track dozer. Handling topsoil in such a manner will <br />minimize deterioration of the biological, chemical, and physical properties of <br />the topsoil and will prevent excess compaction and contamination of the <br />topsoil. Topsoil will not be handled when saturated either during the initial <br />MR -153 2.05-66- 06/14 <br />
