Each topsoil and subsoil lift will be placed at its final thickness over whatever area a single truck <br />load can cover at a given time. When an truck load is dumped onto an area, the dozer operator <br />will only spread the material out over an area that can be covered at the required thickness. <br />This will minimize compaction, since the dozer will not be retreading over previously placed <br />material to place a new layer. This process will take place twice over Prime Farmland areas due <br />to the two separate lifts of soil. <br />Non -prime farmland: Placement of single lift soils on non -prime farmland will follow the same <br />procedure as used for all lifts on Prime Farmland areas. <br />11.0 Topsoil Replacement <br />The topsoil replacement for the mine is divided into the three original topsoil study areas. These <br />are discussed in the following subsections. <br />11.1 Topsoil Replacement - 1988 and 1995 Study Areas <br />These study areas are located east of 2700 Road. As of February, 2008, this area has been <br />stripped, replaced and reclaimed. The various tracts had different topsoil placement <br />thicknesses depending upon landowner and land use. The material replaced, as reported in the <br />Annual Reports, is shown on Map 2.05.4 -4. As is seen from the Map, most of the area was <br />stripped and replaced in 2 lifts. In some cases, the combined lift thickness is reported on the <br />Map. <br />During the topsoil stripping, a deficit was encountered in the amount stripped compared to the <br />amount predicted from the soil survey. WFC proposed the use of selected overburden or <br />interburden materials, approximately 33,600 cubic yards as topsoil substitutes or plant seedbed <br />media for this area, which is 9.7 acres immediately north and west of Pond 07. See Map 2.05.4- <br />4. This is based on the fact that this area had poor topsoil in the beginning (Soil Unit 810), and <br />the lower than anticipated recovery of 80 percent for the remaining Soil Units 1E, 1EW, 808, <br />30C in the surrounding area. The substitute soil was shown to be suitable and has been <br />acceptable in the reclamation. This change was approved and the replacement work was <br />Revised September 2010 (PR 06) 2.05.4(2)(d) -25 <br />
