This shows that the plan can be accomplished with the soil on site, but it does not <br />mean that there will be soil left 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) * 43,560f`Z a, *Soil Thickness (in) <br />12 /t * 27 f`' yd 3 <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 />ERMR-Benson West and about half of the ERMR-Lloyd property. This area is shown on Map 2.05.4- <br />9 as Zone 5. Mixed Topsoil was placed atop of Bench 1 material in Zone 5. Some samples of the <br />Bench 1 material were taken in 2008 from this area and tested; however, no additional testing will be <br />done on this material in this area. <br />February 2018 (RN -07) 2.05.4(2)(d)-17 <br />
