receipt of a determination of reclamation success. The remainder of <br />the light -use road and creek crossing structure will be reclaimed prior <br />to the end of the liability period if not approved for permanent <br />retention. <br />Reclamation Cost Estimate <br />A detailed estimate of the cost of reclamation of the proposed <br />operation must be based on an approved reclamation plan. Prior to <br />final approval of the permit, Northfield will include a detailed <br />reclamation cost estimate in an exhibit which will be the basis for the <br />reclamation bond surety for the mining operation. Additional bonding <br />information for the proposed Northfield Mine is included in Section 3.0 <br />of the application. <br />Facilities Removal <br />After sealing mine openings, Northfield will begin demolition, salvage, <br />and removal of all mine facilities not approved for retention to support <br />the postmining use. Northfield expects that much of the equipment in <br />use at the mine such as conveyors, screening and crushing <br />components, hoppers, electrical installations, truck scale, and <br />prefabricated buildings will be salvaged and removed for profitable use <br />at other industrial sites. Equipment not salvaged will be dismantled, <br />and any buildings that are not salvaged will be demolished. The <br />salvaged equipment and buildings will be hauled from the site by the <br />operator or by salvage contractors. <br />During demolition activities, large equipment and structures will be cut <br />to sizes that can be safely moved by mobile equipment. Most of the <br />metal resulting from demolition will be sold to and removed from the <br />site by salvage contractors. The remaining metal scrap along with <br />concrete debris from slabs and foundations will be loaded and placed in <br />designated disposal areas. Northfield will obtain all necessary county <br />and landowner approvals prior to burying any demolition debris on the <br />site. <br />Areas proposed for demolition debris disposal will be within the slope <br />portal, ventilation shafts., and sections of the bench cut along the west <br />side of the facilities area. Concrete will be broken to the extent that it <br />can be moved for disposal. It will be placed and compacted to <br />minimize voids that may cause slumping of the overburden used to <br />cover the debris. All concrete and metal debris will covered by backfill <br />and topsoil materials totaling a minimum of two feet of suitable cover <br />material. <br />2.05.4 -4 Revised 12/04/09, TR -01 <br />
