-2- According to surveys performed in 1991, the following topsoil is available in storage areas : CUBIC LOCATION YARDS TONS Main Sutey stockpile 65,600 69,077 New Sutey stockpile 24,000 25, 272 Sutey access road 2, 500 2, 632 Tunnel ponds 1, 270 1, 337 Tunnel refuse pile 2, 100 2, 211 #1 Mine ponds upper 106 112 #1 Mine ponds lower 70 74 #5 Mine pond 254 267 Bathhouse 1, 110 1, 169 Overland conveyor 8, 300 8, 740 TOTAL 105, 310 110, 891 It appears that there could be a deficit of up to 44, 487 cubic yards ( 46,844 tons) of topsoil . However, since the topsoil demand is thought to be a maximum, the actual deficit will be smaller . In addition, there are areas close to the sites where there is now little or no topsoil stockpiled, specifically the mine pads, from which additional topsoil can be "borrowed" at less expense than hauling it from the lower stockpiles . These areas are the beaver pond area below the No. 3 Mine bin; an area north of the old Coal Basin townsite adjacent to the No. 5 Mine road; the hillside north of the old training building adjacent to the No. 2 Mine bin site; and several small locations along the No. 4 Mine road . These locations are thought to contain sufficient soil thicknesses to allow removal of the amounts necessary as well as their own subsequent reclamation. It should also be noted that there is considerable rich topsoil in the shallow bowls above No. 4 Mine, along the road to the top of Huntsman Ridge. Clearly, if more than 6 inches of topsoil is required, if road surfaces and/or downslopes must be covered, and/or if the mine pad downslopes must be covered, more "borrowing" will be required, increasing the areas that will have to be disturbed . Specifically, if the old and Sutey refuse piles require 12 inches instead of 6, an additional 48, 239 cubic yards (50,795 tons ) will be needed; if the requirement is 18 inches, 72, 358 cubic yards ( 76, 193 tons) would have to be excavated from somewhere in the basin. To put this in some perspective, the volume of the latter would be that of a square football field ( 100 yards on a side) almost 23 feet high.
