material suitable for topsoil are found, only as much material as required to obtain a uniform <br />reclaimed topsoil depth (close to the average topsoil depth) was removed. Only deposits <br />located in areas that would be disturbed for other reasons were utilized for reclamation. The <br />remainder of the material was separately removed, stockpiled and replaced as subsoil or <br />cover material. <br />Topsoil handling procedure as discussed above will be followed for the refuse areas to be <br />constructed in the future. In order to minimize cheatgrass competition on permanent <br />reclamation areas, topsoil shall be stripped to place the first 6" of material on the bottom of <br />the lift. Similar procedure will be followed while handling cheatgrass infested topsoil <br />stockpiles. <br />The stripping of material to be used as cover for special non-coal wastes or coal waste banks <br />in the waste disposal area was done after the topsoil was stripped. Material which was to be <br />stored was treated in the same manner as a permanenttopsoil stockpile. Since the thickness <br />of available cover material varied, the stripping depths were varied in order to obtain enough <br />material to provide the required cover. <br />Topsoil will be redistributed as promptly as practical. Grading work will be programmed to <br />have finished slopes available on which to place topsoil as it is being stripped, where <br />possible. This planning minimizes disturbed areas and topsoil handling. Permanent <br />stockpiles of topsoil, for use during final reclamation, are placed on stable surfaces within the <br />permit area where they will not be subject to additional disturbance, wind erosion, or <br />compaction during mine life. Ditches are constructed above all topsoil stockpiles which are <br />not located adjacent to a ridgeline, to prevent runoff from adjacent areas from entering the <br />stockpile areas. Side slopes of topsoil stockpiles are not greater than 3h:1 v. Side slopes of <br />non-toxic fill (subsoil) stockpiles are not greater than 2h:1v. Side slopes of 3h:1v or steeper <br />on stockpiles are heavily mulched. <br />Topsoil stockpiles are seeded during the first available favorable planting period after <br />removal. The stockpileswill not be disturbed priorto topsoil redistributionor additionswithout <br />prior approval by DMG. <br />The topsoil will be redistributed in a manner which achieves an approximate uniform <br />thickness as required for the postmining land use. On gradual slopes, topsoil will be spread <br />with scrapers, motor graders, and dozers. On steep slopes, the topsoil will be spread with <br />tracked dozers. Excess compaction of the topsoil will be avoided. On slopes of 3h:1v or <br />steeper, the topsoils will be spread and furrowed on the contour or tracked by a dozer to <br />retard erosion and help retain runoff. Topsoil will be protected to prevent excess wind and <br />water erosion before revegetation operations.
