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 -06. 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 -06 <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 -06 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 />1-36 'R ,} <br />'Revision.. �"" l ` 07 <br />VWa� ZI 1 --t�d t3 <br />
