This shows that the plan can be accomplished with the soil on site, but it does not mean that there will be soil left <br />over. All soil will eventually be used for reclamation. <br />As can be seen from Table 2.05.4(2)(d)-3, there is sufficient topsoil and subsoil volume in the <br />stockpiles to complete the topsoil redistribution plan. Since stockpiled soil had rock fragments <br />removed during stripping, the recovery from stockpiles is treated as 100%. The basic calculation of <br />the topsoil required in a given zone is: <br />Topsoil Needed = Zone Area (ac) * 43,560fZ a� * Soil Thickness (in ) <br />12 nl * 27f`3yd3 <br />The size of the stockpiles is determined via detailed surveys conducted on site. All soil thicknesses <br />are designed to the nearest inch, since this is the practical measurement limit for the scale of <br />equipment used at the New Horizon Mine. <br />12.2 North of BB Road/West of 2700 Road <br />These lands include all lands north of BB Road and west of 2700 Road. As of January 2016, there is <br />approximately 110 acres that has been backfilled and topsoiled with Mixed Topsoil that covers all of <br />WFC -Benson West and about half of the WFC -Lloyd property. This area is shown on Map 2.05.4-9 <br />as Zone 5. Mixed Topsoil was placed atop of Bench 1 material in Zone 5. Some samples of the Bench <br />1 material were taken in 2008 from this area and tested; however, no additional testing will be done <br />on this material in this area. <br />January 2016 (TR -70) 2.05.4(2)(d)-17 <br />
