i r <br /> 2 .05.3(5) <br /> • Topsoil will be removed by rubber tired scrapers with the <br /> assistance of tracked dozers. In some instances other topsoil <br /> salvage equipment may be utilized. Topsoil material generated from <br /> the initial disturbance will be stockpiled in one of three <br /> stockpiles shown on Drawing No. 117 . Topsoil stockpiles No. 1, No. <br /> 2 and No. 3 have a capacities of about 25,000, 75,000 and 14,000 <br /> cubic yards respectively. It is estimated that 45.5 acre feet, <br /> 73,400 cubic yards, of topsoil will be salvaged during the initial <br /> disturbance prior to the commencement of mining in Mining Area No. <br /> 1. As mining progresses subsequent topsoil material salvaged will <br /> be directly spread to the regraded portions of the pit. <br /> If it is decided to mine coal from Area 1 and Area 2 <br /> concurrently, then the topsoil from the initial mining area in Area <br /> 2 will be stripped and placed in topsoil stockpile No. 2 . This <br /> stockpile has enough capacity to contain the 30,000 cubic yards of <br /> topsoil that would be salvaged from the initial mining area in Area <br /> 2 . If mining Area 1 and 2 are developed sequentially, then most of <br /> the topsoil material salvaged from the initial mining area in Area <br /> 2 will be directly spread to the regraded portions of mining Area <br /> 1. <br /> Exhibit 7 contains a topsoil inventory by mining area. This <br /> tabulation lists the area, depth and volume of topsoil to be <br /> • salvaged from Mining Area No. 1 and No. 2 . Exhibit 7 also contains <br /> a tabulation of the amount of acreage and volume of topsoil that <br /> will be disturbed and handled during the initial disturbance and in <br /> one year increments during the permit term. <br /> Mining area 2 has an average of over 20" of topsoil available <br /> for salvage and replacement. Mining area 1 has just over 10" <br /> available. There is a possibility that Mining Area No. 2 will not <br /> be mined because of coal quality considerations. There was a prior <br /> commitment to "borrow" topsoil from area 2 so 12-inches of topsoil <br /> could be placed over all of area 1. Because of the uncertainty <br /> regarding area 2, only 10-inches of topsoil will be placed on the <br /> reclaimed areas of mining area number 1. <br /> • 2 .05-10 May 1992 <br />
