and the permanent stockpile locations. Table A-10 summarizes the results of each haul <br /> route. TALPAC software was used to calculate production rates. The total amount of <br /> topsoil required to replace all disturbance during worst case bond year 2022 is 2,556,495 <br /> cubic yards. Output from TALPAC is included in Appendix A. <br /> Map M6, Bond Worst Case Year, 2022, shows the disturbed area, topsoil pile locations, the <br /> location of final cuts, and regrade cross-section locations. <br /> 1.4.3 Facilities Removal <br /> The estimate for the cost of facilities removal is presented in Table A-12 of Appendix A. <br /> This estimate was generated by applying unit costs for demolition work, as referenced in <br /> bond calculations generated by DRMS for Trapper Mining Inc.'s RN-07. The major <br /> demolition costs are associated with the buildings. These estimates are broken out to <br /> reflect structure demolition, concrete removal both for flatwork and footings, and material <br /> disposal. <br /> The costs for miscellaneous items were generated by applying unit costs from the RN-07 <br /> bond calculation. The operation of the industrial waste pond is described in Section 4.3.2.2 <br /> and is not expected to require more than a minimal effort at the time of reclamation. <br /> 1.4.4 Revegetation <br /> All Areas where topsoil had been placed back over disturbed ground would require the <br /> establishment of permanent vegetation in order to prevent erosion and make the land <br /> productive as either cropland or rangeland (refer to Section 3.6). Table A-11 summarizes <br /> the calculation of a total revegetation cost for each post-mining land use by areas as based <br /> upon total estimated costs per acre and the number of affected acres. <br /> The costs per acre are detailed in the RN-07 bond calculation according to equipment <br /> production costs, material costs, and estimated operating rates for each land use. The <br /> equipment costs were based on equipment types similar to the equipment presently being <br /> utilized at Trapper Mine for reclamation work. <br /> 1.4.5 Miscellaneous Costs <br /> Various miscellaneous costs are addressed in Appendix A. A summary of these costs is <br /> shown in Table A-13. <br /> Revision: P2-o9 <br /> 1-36 <br /> Approved: <br />
