This <br />volume is sufficient to cover the entire disturbed area (20 acres) <br />with 22 inches of soil, which exceeds the 16-inch depth commitment. <br />Approximately 806 cubic yards now stockpiled will be distributed <br />over the abandoned tipple area located off-site to aid in the <br />revegetation of that area. The stockpiles on-site have been <br />located around the perimeter of the facilities to provide a visual <br />screening. Stockpile locations are shown on Figure 9.9-3. <br />9.9.2.3 Grading and Site Preparation <br />Following construction, the stockpiles and the disturbed areas not <br />taken up by facilities constructed during this phase will be graded <br />to the contours shown in Figure 9.9-3. Unless physically retained, <br />the slopes will be 3:1 or flatter wherever possible. Most of this <br />site grading has already been accomplished. The areas that have <br />been shaped include the cut and fill slopes of the facilities pads, <br />any unused portions of the pads, and the topsoil stockpiles. <br />Prior to revegetation, <br />a suitable seedbed. <br />contour where possible. <br />NCIG - Coal Ridge #1 <br />areas will be ripped or harrowed to produce <br />All operations will be conducted on the <br />4-56 <br />ABC/1145/910801 <br />
