Mine Fan <br />Upon completion of mining, the fan and motor will be removed from the foundation and taken from the site. This will <br />involve unbolting the fan and motor from their respective foundations. The pre-engineered building will be torn down <br />and buried in the pit. The duct work and concrete pad or footers will be left in place and buried during reclamation of <br />the portal area. <br />[n reference to the transformer, it will be removed from its pad and removed from the site. The additional power poles <br />will be knocked down and pushed into the portal excavation area during reclamation activities. Likewise, the <br />transformer pad will be pushed into portal area during reclamation activities. <br />Coal Handling Svstem <br />The coal-handling system is part of the mine surface facilities and site reclamation (grading, drainage restoration, <br />soil replacement, and revegetation) will be completed in conjunction with overall reclamation of the surface <br />facilities area. Significant additional rough grading will not be required to address reclamation of the coal handling <br />system. Prior to rough grading the coal handling facilities areas, all usable coal-handling equipment will be <br />removed and salvaged, and the ROM Stacker Tube, Sampling Station, Primary and Secondary Crusher Buildings, <br />Sample Building, and associated conveyors and related structures will be dismantled and removed from the site or <br />demolished. The top and upper portion of the sides of the ROM Reclaim Tunnel and lateral structures will be <br />broken-up and placed into the tunnels. After removal or demolition of the buildings, structures, and conveyors, the <br />related concrete foundations will be demolished. Any concrete or structural debris resulting from demolition of the <br />coal-handling facilities and related foundations will either be placed in the mine portal area and buried, or disposed <br />of off-site. The associated disturbance areas will then be backfilled and rough-graded to blend with surrounding <br />terrain. In conjunction with site regrading, any surplus fill material not required to establish the design postmining <br />configuration will either be hauled back to one of the original borrow sites, or if suitable material, may be used as <br />cover for the Coal Refuse Pile. Topsoil will be replaced on the regraded areas from the designated topsoil <br />stockpiles, and the areas will be reseeded with the approved revegetation seed mixture. <br />The Overland Conveyor access corridor will be ripped to a depth of approximately 24 inches and the windrowed <br />topsoil will be redistributed over the corridor. The redistributed topsoil will be seeded with the rangeland seed <br />mixture. The drive building will be dismantled and either removed from the site or hauled to the portal area for <br />burial. The foundation materials will be handled in the same manner. <br />Washplants I and H <br />The coal-handling system is part of the mine surface facilities, and site reclamation (grading, drainage restoration, <br />soil replacement, and revegetation) will be completed in conjunction with overall reclamation of the surface <br />facilities area. When no longer required, all usable coal processing equipment will be removed and salvaged, and <br />the Crushing/Screening and Washplant Buildings and associated conveyors and related structures will be <br />dismantled and removed from the site or demolished. The structures to be removed include the Crushing/Screening <br />Building; Washplant I and the related clean coal, stoker, and refuse conveyors and structures (includes Thickener <br />Tank and Refuse Bin); Washplant 1[ and the related clean coal, stoker, and refuse conveyors and structures <br />(includes Thickener Tank and Refuse Bin); and the Washplant Sub-Station, and the associated power distribution <br />line. After removal or demolition of the buildings, structures, and conveyors, the related concrete foundations and <br />manholes will be demolished, and utilities and the Thickener UnderFlow Pipelines will be stubbed-off below grade <br />and abandoned in-place. Any concrete or structural debris resulting from demolition of the washplant facilities and <br />related foundations will either be placed in the mine portal area and buried, or disposed of off-site. <br />The Thickener UnderFlow borehole will be plugged and sealed, consistent with normal plugging and sealing <br />methods. The associated disturbance areas will then be backfilled and rough-graded to blend with surrounding <br />terrain. In conjunction with site regrading, any surplus fill material not required to establish the design postmining <br />configuration will either be hauled back to one of the original the borrow sites, or if suitable material, may be used <br />as cover for the Coal Refuse Pile. After structure removal and backfilling, the site will be topsoiled and seeded <br />with the approved seed mixture. The topsoil replacement will involve redistributing the 9,300 CY of topsoil that <br />was placed in stockpile SF-4 (3,300 <br />TR07-60 2.05-102 05/22/07 <br />
