This information is presented on the Bond Reclamation Map Maximum Disturbance <br />Topography -North, Map 34, and Bond Reclamation Map Maximum Disturbance Topography - <br />South, Map 35. Disturbance acreages, as indicated by these maps for each disturbance area, aze <br />summarized in Table 1, Disturbance Area Acreages. <br />5.0 DETERMINATION AND SEQUENCING OF REQUIRED RECLAMATION <br />FUNCTIONS <br />Having identified the bonding disturbance scenario, the next step in developing the <br />bonding cost estimate was to determine what reclamation functions or activities would be required <br />to reclaim disturbance azeas in accordance with the approved reclamation plan. Inherent in the <br />determination of the required reclamation functions was the development of a logical sequence of <br />reclamation activities for each disturbance area. The following reclamation functions and <br />sequencing were identified as being selectively applicable to specific disturbance areas: <br />1) Removal and disposal of mine structures and facilities <br />2) Ripping, removal, and disposal of surfacing materials <br />3) Ripping of surface material to alleviate compaction <br />4) Rough grading of roads and facilities azeas <br />5) Recontouting excavated areas <br />6) Reestablishment of drainage <br />7) Replacement of stockpiled topsoil material <br />8) Revegetation of all reclaimed areas <br />9) Removal of sedimentation ponds and reclamation of pond azeas <br />6.0 DETERMINATION OF MATERIAL HANDLING REQUIREMENTS AND <br />DELINEATION OF HAULAGE ROUTES <br />In order to develop cost estimates for completion of various reclamation functions, it was <br />first necessary to quantify the volumes of material to be handled. <br />Debris from facility removal can be effectively disposed of in regraded fill areas with no <br />adverse effects. These materials will be placed above the natural water table and will be covered <br />by a minimum of four-feet of suitable material. This approach precludes the unnecessary <br />additional cost of hauling this material off site to a landfill. <br />Recontouring volumes reflect grading of the disturbance azeas to eliminate all highwalls, <br />establish stable slopes at a maximum grade of 3:1 and create a bond reclamation configuration, <br />which provides for effective drainage. Recontouring volumes were developed by first <br />4 Revision Date: 5/8/03 <br />Revision No. TR-56 <br />
