All of the areas addressed in this project contained many large concrete building and <br />beltline foundations and footers. The concrete materials were demolished and hauled to <br />various locations. The concrete debris generated from the overland conveyor and upper <br />coal stockpile area was placed at the base of the coal stockpile cut slope. The debris <br />generated from the lower stockpile azea was placed against the cut slope in that area, <br />located below, and south of, Road A. The debris from the wazehouse area was hauled to <br />the base of the north facing cut slope behind the former location of the thermal dryer <br />facility. Each area was graded to a geomorphically stable landform. The overland <br />conveyor corridor was graded to drain water to the south for its entire length. The coal <br />stockpile areas were graded to eliminate the highwalls, generally resulting in 2H:1 V to <br />2.SH:1 V slopes. Fill to cover the lower stockpile azea was generated by pushing the <br />outside of Road A down slope over the concrete rubble, thus reducing the road width <br />from sixty to thirty feet. The warehouse area was graded to drain to the east through a <br />constructed drainage channel. A limited amount of topsoil was available, so it was <br />preferentially placed over the upper coal stockpile backfill, on the floor of the lower coal <br />stockpile azea and at the wazehouse azea. A drainage channel was constructed to convey <br />water from the upper stockpile to the warehouse drainage system. This rock-lined <br />drainage is located on the south side of Road A, near the easterly mazgin of the upper <br />coal stockpile. <br />The upper coal stockpile backfill suffered a small slope failure the winter following <br />reclamation. The failure was apparently caused by water being trapped at the junction of <br />the base of the cut slope with the backfill material. The failure was excavated in the <br />summer of 1998, and a rock filled underdrain was constructed. The fill was replaced at <br />the site of the failure, and the area re-seeded. <br />The areas affected by this project aze privately owned. <br />1997 Reclamation Summ <br />Pro'ect Acrea a Reclaimed Current Ownershi <br />Tree Plantin Project 5,000 * Public <br />Mine 4 Revegetation Project 12 Public <br />Warehouse Vicinity <br />Reclamation <br />18 <br />Private <br />Spring Maintenance 0 Public /Private <br />* Number of trees planted <br />1998 <br />Sarin Maintenance.
