added to drain the water from the northern part of the stockpile into Pond E. This does not increase the drainage <br />area tributary to Pond E, therefore, Pond E does not require resizing. Two culverts were placed in this ditch to pass <br />water under an access point into the stockpile and under the haul road. The design information for the ditch and <br />culverts is contained in Exhibit 8. <br />The ROM Coal Stockpile area will be reclaimed when no longer required for processing run of mine coal. Above- <br />grade structures will demolished and disposed of in the portal area, and the area will be regraded, topsoiled, and <br />revegetated with the appropriate seed mixture. <br />ROM Stockpile Facilities Additions <br />Several planned upgrades for the facilities around the ROM stack tube were completed to allow for more efficient <br />handling of coal. These upgrades include installation of anon-powered tripper on the coal belt between the transfer <br />building and the stack tube, extension of the ROM reclaim tunnel, and installation of four additional feeders, and <br />moving the MCC No 1. Fan-House/Escape Tube. <br />The non-powered tripper on the coal belt between the transfer building and the stack tube allow for coal to be <br />dropped off the belt approximately 160 feet south of the stack tube. This reduces the amount of pushing required <br />by dozers on the pile. The structural framework was extended from the revetment at bent #4 and a tripper <br />arrangement installed on this framework. The system is arranged with moveable chutework, so that the chutework <br />can be moved into the coal stream coming off the tripper and dischazge coal to either side of the revetment. The <br />design of the chutework results in an open-type dischazge similar to the BOB discharge. <br />The reclaim tunnel was extended 180 feet to the west reducing the length of dozer pushes away from the tube and <br />back to adraw-point. The reclaim tunnel extension is a multi-plate arch 180 feet long, 12 feet wide, and <br />approximately 8 feet high, constructed of 8-gauge corrugated metal plate. The liner is supported by a concrete <br />footer extending 180 feet to the west of the existing tunnel on both sides of the overland belt. The footers are 4 feet <br />wide and 2 feet thick with a 12-inch stem wall extending 3 feet up from the footer. As part of this extension, one <br />additional feeder was installed within the multi-plate azch. <br />Three additional feeders were installed in the ROM reclaim tunnel. These feeders are located in the legs of the "H" <br />vault area, specifically the northeast, southeast, and southwest legs. Installation of the feeders in the tunnel <br />involved connecting the feeders to existing draw-point chute-work and modifying the skirtboard hoods to accept the <br />feeder discharge. <br />The MCC No. 1Fan-House/Escape Tube buildings were moved approximately 200 feet to the north to allow for <br />coal storage in the pad area south of Haulroad B-1. Technical Revision 18 addressed the necessary grading for <br />expansion of the stockpile to the north. The pad azea is currently pemutted for coal storage but is being used for <br />temporary equipment storage. Map 24 has been revised to show this area as both ROM coal stockpile and <br />equipment material storage. <br />When no longer needed to support coal handling operations, the concrete associated with the tunnel will be broken <br />up and buried on-site and the steel will be either salvaged or disposed of on-site. The buildings will be removed <br />when the ROM facilities are dismantled. <br />Coal Handlin¢ Svstem Uperades <br />Expansion of mine production and coal handling capacity to 10 million tons per year required additional conveyors <br />and facilities, which were added to or replace existing systems, to handle the increased production. The existing <br />transfer building remains and another transfer building was constructed to the south of the existing building. Anew <br />Run-of--Mine (ROM) conveyor belt was installed to convey coal to the coal stacking tube/raw coal stockpile. An <br />additional conveyor was also installed to handle the waste rock generated by the mining process. A metal slope <br />belt-drive building with dimensions of 32 x 40 x 20 feet, located north of the existing transfer building, was <br />TR06-53 2.05-26 06/20/06 <br />
