7.0 New Horizon 2 Mine Topsoil Management Plan General Considerations <br />The following subsections have been revised for TR -57 in 2008 and PR -06 in 2010, which <br />addresses the topsoil replacement for the whole permit area, including the change in handling <br />procedures due to the determination of prime farmland soils in the western portion of the permit <br />in February 2008. <br />The New Horizon 2 Mine topsoil handling procedures, based upon the detailed soil survey <br />information contained in Section 2.04.9, were developed to insure that the topsoil resources <br />within the disturbance area are salvaged and replaced. The plan outlined in the following <br />subsections focuses on the topsoil replacement that has already occurred (as of June 2010) <br />and describes salvage depths and techniques, storage, redistribution, and maintenance or <br />testing procedures necessary to restore the disturbed areas to the desired postmine land use. <br />Topsoil handling will be minimized to the extent possible, utilizing direct lay down as much as <br />possible. All of the soils on the Morgan property, which are designated as prime farmland, will <br />be stripped in 2 lifts and will meet prime farmland specifications. A minimum of 3.0 feet of <br />suitable subsoil (Bench 1 subsoil substitute material) will provide an additional subsoil base over <br />the prime farmland soil area on the Morgan property. The prime farmland on the Morgan <br />property will receive the same topsoil that was present on the property prior to mining. All Bench <br />1 material stripped after June 2010 on the Morgan property will be salvaged and restored to the <br />Morgan property. <br />Map 2.05.4 -4 shows the required reclamation thicknesses for all subsoil, topsoil and mixed lift <br />soils over the entire permit area. <br />Revised September 2010 (PR 06) 2.05.4(2)(d) -12 <br />
