integrated into the opening seal and the entry areas will be regraded to approximate original <br />contours. <br />The regrading of each level area will be done using the material from the fill portions of the <br />pads and any excess material from the haul and plant access road. This material will be <br />generally pushed back against the cut areas from where it originally came until the level <br />areas are eliminated and there is no discernible break in slope. The final layers will <br />subsequently be furrowed and scarified before topsoiling. The slope of the regraded surface <br />will be varied to approximate drainages that existed before initial disturbance. Overall, final <br />surface configurations after reclamation will be more stable than the original slopes, since <br />many existing slopes were unstable and highly eroded. No regraded slopes will exceed <br />2h:1v. For areas where fill heights exceed 10 feet, the new fill areas will be keyed into the <br />underlying level area. Cut and fill terraces are not required for stability or erosion control and <br />will not be utilized. <br />Gravel surfaces will be scarified and mixed with the subgrade material during regrading. <br />Concrete pavements, footings, etc., will be buried a minimum of four feet. Pipes, cable, and <br />bituminous material will be separated by contractors and disposed of in an approved fashion. <br />Buried pipelines that will not be disturbed during final grading activities will be left in place. <br />All power lines and pole structures except for the 138-kV lines will be removed. <br />If, after regrading and revegetation, rills and gullies deeper than nine inches form in the <br />regraded areas, they will be filled, graded or otherwise stabilized and the affected area <br />revegetated. <br />Drainage channels created in the regraded sections to conform to the natural terrain will be <br />rip-rapped or otherwise protected as required to prevent erosion. <br />Exposed unoxidized coal seams and refuse disposal areas will be covered with a minimum of <br />2.5 feet of the best available nontoxic, nonacid forming material. The 2.5' cover is a variance <br />from the standard minimum cover of 4 feet. Under such conditions, the compaction and <br />drainage protection procedureswill be as specified by the appropriate regulatory agencies. <br />V.C Removal, Storage and Redistributionof Topsoil and Subsoil <br />All areas to be disturbed at any time during the construction, operation, or reclamation of the <br />mine and its surface facilities will have available topsoil or other suitable growth media <br />separately removed and segregated from otherfll material. Availabletopsoil was determined <br />from the soil assessment contained in Section II.I. Topsoil or other suitable growth media are <br />stockpiled in various locations to be used during final reclamation. In addition, all areas <br />disturbed during the removal of roads, conveyors, or utilities will be covered with topsoil.
