• a depth of 40 inches. This material has been placed in Stockpiles 3 and 4. This material will <br />only be used to reclaim this small area of prime farmland. <br />Topsoil Salvage Techniques - All Study Areas prior to February 2008 <br />Before any area at the proposed New Horizon Mine 2 site other than a topsoil stockpile site is <br />significantly disturbed, the suitable topsoil material will be removed to the depth specified in <br />Table 2.05.4(2)(d)-3, Table 2.05.4(2)(d)-4, and Map 2.04.9-1. Suitable topsoil was salvaged <br />from all significant disturbance areas including sediment ponds (includes pond area, <br />embankment, and spillway), mining activities, spoil stockpiles, haul roads, access roads, <br />mining area (includes box cut spoil and highwall reduction area) shop area, and diversion <br />ditches. Topsoil was removed from all cut and fill slopes. No topsoil was salvaged from the <br />light use roads utilized for environmental monitoring or power line corridors, except where cut <br />and fills are required. Prior to topsoil removal, vegetation which is too large for incorporation <br />into the topsoil was scraped away and combined with the overburden. The remaining <br />vegetation was incorporated into the topsoil to help increase soil organic matter levels. To <br />• prevent unnecessary contamination, adequate extent of topsoil was salvaged from the edge of <br />a road, embankment, ditch, cut slope, and toe of fill. <br />For the original permit area, a two-lift topsoil operation was utilized for the two primary premine <br />irrigated pastureland soil types (30C and D70B), whereby the "A" and upper "B" horizons (Lift <br />A) are salvaged separately from the lower "B" and "C" soil horizons (Lift B) (1988 - 1996 <br />disturbance area). <br />Specific Soil Map Units (1 E, 1 EW, and 808) at New Horizon 2 (1988 - 1996 disturbance area) <br />was more suited for mixed one-lift topsoil salvage because they are very shallow to shallow, <br />have little profile development, and/or are excessively stratified. The salvageable topsoil from <br />these units was primarily utilized, whenever feasible, in postmine dry pastureland area. One-lift <br />topsoil was isolated from the two-lift topsoil during all soil handling operations. <br />For the portions of the 1999 expansion area that were disturbed prior to February 2008, the A, <br />Bt, Bw, Bk and C horizons were combined for salvage in a mixed lift and suitable subsoil <br />• <br />(Revised Nov Zoos) 2.05.4(2)(d)-21
