The chemical properties of the overburden/interburden are also quite favorable. Sodicity and <br />salinity levels are low to moderate in the New Horizon 2 permit area and should pose no severe <br />problem to successful reclamation. Salinity levels in the upper four feet of regraded Bench 1 <br />material will likely be comparable to pre -mining values. <br />The uppermost overburden transitions into the subsoil gradually on the majority of the permit <br />area. Much of this upper overburden is called Bench 1. For the area west of 2700 Road, it is <br />standard practice that Bench 1 material is placed as the top overburden to provide the best chance <br />for reclamation success. The topsoil replacement calculations discussed later in this Section <br />accounts for the use of some of this material. In all areas, Bench 1 is the first spoil below topsoil. <br />This is the same as the pre mine conditions. <br />7.0 Topsoil Management Plan General Considerations <br />The topsoil handling procedures, based upon the detailed soil survey information contained in <br />Section 2.04.9, were developed to insure that the topsoil resources within the disturbance area <br />are salvaged and replaced. The plan outlined in the following subsections focuses on the topsoil <br />replacement that has already occurred (as of late 2011) and describes salvage depths and <br />techniques, storage, redistribution, and maintenance or testing procedures necessary to restore <br />the disturbed areas to the desired post mine land use. <br />The terms "topsoil" and "Bench 1" are used throughout the permit in reference to two vertical <br />portions of soil profiles on site. Topsoil is the uppermost portion, while benchl is the portion <br />immediately below topsoil. <br />Topsoil handling will be minimized to the extent possible, utilizing direct lay down as much as <br />possible. Topsoil and Bench 1 has been stripped from all of the Morgan property as of <br />September 2011, and stockpiled in the piles shown on Map 2.05.4-6. All topsoil and Bench 1 <br />placed on the Morgan property was contained within these stockpiles. <br />Bench 1 and topsoil replacement thicknesses and distribution plans are shown on Map 2.05.4-4, <br />for the entire permit area. Map 2.05.4-6 shows the topsoil distribution and balance for the <br />Morgan Property, and Map 2.05.4-9 shows these items for the areas north of BB Road and west <br />of 2700 Road. <br />8.0 Topsoil Storage <br />All efforts will be made to direct haul and place all topsoil excavated. When the direct haul of <br />topsoil is not feasible, the topsoil will be stored in stockpiles. <br />July 2018 (TR -84) 2.05.4(2)(d)-7 <br />
