3-12 <br />~~ Shown on Figures 3.1-2 and 3.1-3. Figure 3.1-2 is a smaller scale map of the mine site <br />than Figure 3.1-1 and shows detailed reclamation contours of the reclaimed mine site. <br />In general, all coal outcrops will be backfilled with incombustible material, but the <br />naturally occurring outcrops at the head of the two major canyons at the mine site will be <br />exposed. Any attempt to backfill these drainages would encounter problems with <br />erosion. <br />MINE SUPPORT FACILITIES <br />All facilities within the office complex will be removed except for the trees planted <br />for screening, which will be saved if possible. The area will then be regraded to the <br />approximate original contour and the topsoil will be replaced. (See Section 3.3 for <br />topsoil replacement). As the office area is regraded to AOC and topsoiled, the landform <br />will assume to predisturbance slopes allowing any runoff to be directed to the natural <br />sediment trap which forms part of SAE-1. <br />The access road will also be ripped to break up the compacted road base. After <br />ripping, a portion of the material may be used for any further reshaping of adjacent areas <br />to achieve approximate original contours. Excess material will be spread along the <br />alignment to approximate the original contours and break up the "straight lines" of the <br />alignment. The area will then be topsoiled and reseeded. Silt fence or straw bales in <br />conjunction with the mulch used in the seeding process will effectively control runoff and <br />sedimentation. <br />The disturbed area created as part of TR-16 (2008) excluding the Coal Mine <br />Waste Pile, will be regraded to AOC, topsoiled and seeded. <br />TR-16 M`-Volume 1 (Rev 05/08) <br />
