assigned to a particular structure or its materials will change during the time for which the overall reclamation is bonded. One common problem in the setting of a salvage value for a particulaz item is the assumption that its value will remain constant, with no reduction in its value over time. The usual change in an onsite structure's value is, of course, a reduction in value, due to a combination of factors, including ongoing mine-related use, natural weathering or deterioration, and vandalism. Even new structures at well-guarded sites experience decreases in their values; the values of aging and weathered structures at poorly- guarded sites decrease more rapidly. Plus, if the operator wishes to lessen the amount or rate of decrease of the salvage value of a structure, it is imperative that precautions be taken to provide for site security, and to monitor and maintain the structure. Please also refer to Hard Rock and Metals Rules 4.3.9 (Salvage Value), 4.3.10 (First Priority Lien on Project- related Fixtures and Equipment), and 4.9.3 (First Priority Lien -Fixtures and Equipment). These rules explain the additional need for an operator to ensure that the State has clear title to the salvaged item. This mechanism acts the same as the assignment of a bond to the State. To assign a meaningful salvage value, therefore, requires that a structure's condition be verified on a frequent basis Please refer to Rule 4.1.2(5), which describes the operator's obligation to annually file an independent certification of the item or structure whose salvage value is being used as part of the posted bond. The costs of the process of setting the salvage value and regularly reviewing it are additional to the operator's normal annual fees. Please also refer to Rule 4.1.2(9)(a)-(d), which explains the operator's burden ofpaying the Division an annual fee for establishing and reviewing the bond (salvage value). In summary, without the practices of safeguarding and maintaining the condition of an item, the filing of the outside certification, payment of the fees for the annual review and verification of the (bond) value of an item, and the agreements and assurances in place giving the State the priority lien for the (value of that) item, this office cannot approve a reduction in bond amount for salvage value. The costs of the tasks of demolishing the superstructures and slabs of the buildings onsite, and the backfilling of the rubble into an onsite pit, are estimated figures based on can-ent operating costs, taken from the Caterpillar Performance Handbook and Contractor's Reference Guide. These utilize current labor, fuel and equipment rental costs. They additionally incorporate actual productivity figures from the DMG Abandoned Mine Land program's reclamation and closure projects. You stated that the demolition should take 2 weeks and not 3 weeks. The demoliton task sheet contains a figure of 80 hours, or 2 weeks. This task actually includes more than just building demolition; it includes removal of miscellaneous debris, ventilation fans from the remote sites, plus plumbing and electrical. If you have production figures that better represent these reclamation needs, please provide them. Otherwise, this office must retain these cost figures in the estimate. 5) The issue of allowing salvage value for the NC-owned electrical transformers is also guided by the requirements set forth under item 4, above. While there may be salvage value and a market of willing buyers for used electrical transformers, the State does not include those in its bond estimates. Again, it is the operator's burden to provide the necessary figures, fees, and agreements for establishing these items as part of the bond. 6) The grading of the dump slopes is required as part of the reclamation plan, to the extent that a 2:1 gradient is attained (as discussed under item 2, above). You stated that the coarse and angular nature of the waste rock will preclude the ability to move it with scrapers. This point is well taken. Therefore, while the need to move the material remains, costs for this task will be revised to utilize different types of equipment. Equipment to be considered includes a large tracked excavator and large dozer.
