TOPSAND <br />Quantities Required <br />B -Pit (24 inches) <br />Long-term spoil area (15 inches) <br />Topsand piles A-1, A-3, B-1 and B-2 (6 inches) <br />Access Roads (24 inches) <br />Total <br />Stockpiled Quantities <br />Topsand piles A-1, B-1, B-2 and A-3 <br />Total Remaining <br />103,921 BCY <br />98,817 BCY <br />16,408 BCY <br />12,907 BCY <br />232,053 BCY <br />299,187 BCY <br />- 232,053 BCY -from above <br />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 />
