• 1.4.3 Facilities Removal <br />The estimate for the cost of facilities removal is based on escalation of the value <br />approved in early 2006. A 5% escalation was applied to account for unit cost increases. <br />The 2006 estimate is based on data from RS Means Building Construction Cost data <br />and information from DRMS. <br />1.4.4 Reveaetation <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 1.4-10 <br />summarizes the calculation of a total revegetation cost for each post-mining land use by <br />areas as based upon total estimated costs per acre and the number of affected acres. <br />The costs per acre are detailed in Tables 1.4-11, 12, 13, and 14 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 <br />being 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 1.4-16. <br />11 <br />Revision: 04-0 L <br />1-53 Approved.
