• Openings that are allowed to remain after mine operations cease will have frames and gratings installed as indicated above. V.G Backfilling and Contouring Except for the upgraded county road and coal waste banks in the disposal area, all surface areas that are disturbed incidental to the mining activities will be backfilled, graded to approximate original contours, and revegetated. Excess material from the haul road and plant access road will be transported to the D Portal Area and used in backfilling and regrading. Disturbed areas that will be regraded are indicated on Maps 43, 44, 45, 46, 47 and 47A ("D" Portal), Maps 40, 41, and 42 (Scullion Gulch Diversion), Map 89 (Ventilation Entry and Access Road), Map 81 (Refuse Disposal Area), Map 103A and 104 (Railroad Loading Area), Map 69 (Haul and Access Road), Map 55 (Water Storage Area), and Map 92 (Alluvial Well Area), and Map 151 (B Seam ventilation shaft facilities and access). In addition, areas disturbed during utilities removal will be regraded and revegetated. Base maps with original contours only for most of the above areas are on Map 48, 49, 50, 51, 87, and 88. Disturbed areas that will not be redisturbed during the mine operation or final regrading were backfilled, regraded and revegetated as part of the original construction work. • Concrete portal face walls will be removed along with the corrugated steel entry tunnels not integrated into the opening seal to a minimum of 4' below the reclaimed slope or to bedrock. The entry areas will then be regraded to approximate original contour. The regrading of each level area will be done using the material from the fill portions of the pads and any excess material from the haul and plant access road. This material will generally be pushed back against the cut areas from where it originally came until the level areas are eliminated and there is no discernible break in slope. The final layers will subsequently be furrowed and scarified before topsoiling. The slope of the regraded surface will be varied to approximate drainages that existed before initial disturbance. Overall, final surface configurations after reclamation will be more stable than the original slopes, since many existing slopes were unstable and highly eroded. No regraded slopes will exceed 2h:1v. For areas where fll heights exceed 10 feet, the new fill areas will be keyed into the underlying level area. Cut and fill terraces are not required for stability or erosion control and will not be utilized. Gravel surtaces will be scarifed and mixed with the subgrade material during regrading. Concrete pavements, footings, etc., will be buried a minimum of two feet. Pipes, cable, and bituminous material will be separated by contractors and disposed of in an approved fashion. Buried pipelines that will not be disturbed during final grading activities will be left in place. All power lines and pole structures except for the 138-kV lines will be removed or buried on site.
