MION " <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 87,600 cubic yards and <br />will be spread over 64.0 acres which will provide an approximate uniform <br />stable thickness of nearly 10 -inches. Topsoil stockpiles D & E contain 42,450 <br />cubic yards and will be spread over the 49.8 acre gob pile area which will <br />provide an average replacement depth of approximately 6 -inches. The self- <br />sustaining vegetation is appropriate for the postmining land use of rangeland <br />and wildlife habitat. The 6 -inch topsoil depth for the gob pile area is marginal, <br />however, nutrients or other soil amendments will be applied to redistributed <br />topsoil if necessary to support plant nutrient requirements. Further, testing <br />was done on coverfill material placed on the first bench of gob pile #2 that <br />indicate the growth media was comparable in terms of suitability to topsoil <br />originally projected to exist in the gob #2/4 area. Therefore, the Operator <br />believes vegetation establishment will be adequate, and consistent with the <br />post mining land use of rangeland/wildlife habitat. <br />Topsoil stockpile F will contain 52,865 cubic yards. It will be spread over the <br />23.6 acres of the reclaimed unit train loadout to a depth of approximately 1.3 <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 />MR -168 2.05-66- 11/14 <br />
