Chapter V <br /> Two sediment ponds were constructed, with topsoil salvaged, then spread on the <br /> pond embankments. The embankments have been seeded. <br /> • <br /> f. Adit/Rock Tunnel Area. <br /> In 1979 the tunnel face up work was done and cut areas adjacent to the area were <br /> revegetated. <br /> In 1980 actual mining of the tunnels began and the permanent fill area was <br /> developed by constructing a haul road, topsoil storage area, perimeter road/ditches, <br /> and three sediment ponds. The topsoil storage areas and pond embankments <br /> were subsequently seeded. <br /> By 1987 the tunnel had been driven through the B-bed coal seam to the Middle-bed <br /> seam, and the overland conveyor system to the preparation plant had been <br /> completed. <br /> The overland conveyor route was regraded and seeded with the approved 8000' <br /> seed mixture in the fall of 1987. <br /> A fill area completed in 1987 added an additional 2.6 acres to the adit/rock tunnel <br /> pad. The fill came from excavation of the adit/rock tunnel. <br /> • Vegetation was removed and topsoil was excavated and stored. <br /> An existing topsoil pile (1480 cu. yds.) located in the proposed fill area was moved <br /> to the rock tunnel topsoil storage pile. <br /> 2. INTERIM RECLAMATION. <br /> a. Sutey Refuse Pile. <br /> Mid-Continent has used the Sutey refuse pile since 1985 for deposition of refuse <br /> separated from the salable coal in the washing process. The rate of deposition of <br /> refuse at the Sutey pile depends upon the rock material which must be separated <br /> from the coal. That is to say, factors of nature and, to some extent, customer <br /> preference, determine the rate of expansion of the Sutey pile. <br /> The design and permitting of the pile has proceeded in four phases. Phasing of the <br /> pile relates to the volume of refuse deposited.* Phases I, II and III are currently <br /> permitted. <br /> 13 <br />
