According to the CDMG's definitions, the change in disturbed area associated with PR-05 is accurate and <br />does not include the undisturbed "minimal disturbance" areas. The acreages given below reflect the <br />shaded areas as shown on Exhibit 12-2 and the revegetation map, Exhibit 22-1, Postmining Vegetation. <br />The areas are conservatively overestimated for the reasons stated above. <br />Mine Area: <br />Acres Permitted for Disturbance 1,334.5 ac <br />Acres Actually Disturbed 1,139.9 ac <br />Tie-Across Haul Road: <br />Acres Permitted for Disturbance 200.0 ac <br />Acres Actually Disturbed 96.6 ac <br />Total Disturbed Area: <br />Acres Permitted for Disturbance 1,534.5 ac <br />Acres Actually Disturbed 1,236.5 ac <br />Backfilling and Grading Procedures <br />Rough grading will be performed with bulldozers, scrapers, graders and, occasionally the dragline. <br />Bulldozers and scrapers are used for final grading. SCC does not plan to remove any necessary <br />reclamation equipment from the area of operation until final reclamation is completed. Typically, the <br />process of grading begins with bulldozers building roadways into the ungraded spoil. Once sufficient <br />access into the spoil is provided, dozers or scrapers move the spoil material in the direction and the <br />amounts required to achieve the desired land form. The movement of spoil material is generally <br />downslope, due to economic and safety considerations. Completion of rough backfilling and grading will be <br />attempted within 180 days following coal removal unless specific variances are applicable. Backfilled <br />materials shall be placed to minimize adverse effects on ground water, minimize off-site effects, and to <br />support the approved postmining land use. The mine site will require a variance from contemporaneous <br />reclamation for specific areas and situations as described in Tab 19. <br />SCC's experience has shown that grading two spoil ridges simultaneously produces more desirable <br />reclamation results than grading one spoil ridge at a time. This is because the creation of graded slopes is <br />primarily dependent upon the ability to perform "area grading" versus grading one spoil ridge. Because of <br />many variables encountered in the overburden removal process, it is very difficult to predict the exact, final <br />configuration of the spoil. Thus, the final planning for reclamation grading must be performed after the <br />TR-59 2 Revised 05/07 <br />
