3-12 ~o-.y shown on Figures 3.1.2 and 3.1-3. figure 3.1.2 is a smaller scale map of the mine site than Fgure 3.1.1 and shows detailed reclamation contours of the reclaimed mine site. In general, all coal outcrops will be backfilled with incombustible material, but the naturally occurring outcrops at the head of the two major canyons at the mine site will be exposed. Any attempt to backfill these drainages would encounter problems with erosion. MINE SUPPORT FACILITIES All facilities within the office complex will be removed except for the trees planted for screening which will be saved if possible. The area will then be regraded to the approximate original contour and the topsoil will be replaced. (See Section 3.3 for topsoil replacement). As the office area is regraded to AOC and topsoiled, the landform will assume to predisturbance slopes allowing any runoff to be directed to the natural sediment trap which forms part of SAE-1. • The McClave to Munger road will be regraded and topsoil will be replaced. The bulk of this process will involve ripping the compacted roadbase and using the ripped material to reshape the land for topsoil replacement. As the topsoil is replaced, to a depth of 18 inches, the approximate original contours will be reestablished. The area will be nearly level'so that the minor amounts of runoff that will occur can be controlled with silt fence and straw bales. The access road will also be ripped to break up the compacted road base. After ripping, a portion of the material may be used for any further reshaping of adjacent areas to achieve approximate original contours. Excess material will be spread along the alignment to approximate the original contours and break up the "straight lines" of the alignment. The area will then be topsoiled and reseeded. Sift fence or straw bales in conjunction with the mulch used in the seeding process will effectively control runoff and sedimentation. A~ Volume 1 6-29.96
