TOPSAND <br /> Quantities Required <br /> B-Pit(24 inches) 103,921 BCY <br /> Long-term spoil area(15 inches) 98,817 BCY <br /> Topsand piles A-1, A-3, 13-1 and B-2 (6 inches) 16,408 BCY <br /> Access Roads (24 inches) 12,907 BCY <br /> Total 232,053 BCY <br /> Stockpiled Quantities <br /> Topsand piles A-1, B-1, B-2 and A-3 299,187 BCY <br /> -232,053 BCY-from above <br /> Total Remaining 67,134 BCY-- surplus <br /> CEC will replace 24 inches of topsand on the A- and B-Pit disturbed areas, as well as on the <br /> temporary access and haul roads. The long-term spoil area will receive 15 inches of topsand and <br /> the topsand piles will receive six (6) inches of topsand over the in-place sub-soils. <br /> Most of the temporary topsand storage piles have been flattened to a 20 percent(20%)slope or <br /> less. This is the maximum slope encountered over the original ground surface in the existing <br /> CEC permit area and vicinity. Topographic maps indicate that 20% slopes are maximum and the <br /> overall land slope on the CEC permit area is roughly 2.5%. <br /> Upon completion of the A/MWR disposal operation in either pit area, all waste will be removed <br /> or buried to prevent water pollution or adverse visual impacts.Non-salvageable materials will be <br /> buried in the pits above the local ground water levels, and at least to four(4)feet below AOC. <br /> The final pit highwalls will also be backfilled to AOC. It is noteworthy that there are no acid- <br /> forming materials in the coal seam per indications in the sump water data(refer to Section 2.04.7 <br /> in this document). <br /> Structures previously used in the CEC mining operation that are outside of the area with a <br /> designated post-mining land use of Industrial/Commercial will be removed, and the local ground <br /> area will be scarified, topsanded, fertilized and revegetated. Facilities and parking areas within <br /> the area designated as a post-mining land use of Industrial/Commercial will not require any <br /> additional reclamation work to satisfy reclamation liability and bond release requirements. <br /> 114b 06/15 <br />
