additional conveyor was also installed to handle the waste rock generated by the minin r belt-drive building with dimensions of 32 x 40 x 20 feet, located north of the existing transfer building, w,~ constructed in 1995, and provides electrical and mechanical support for conveyor s stemp ocess.

The location of the belt has been modified to &cilitate operations around the s orage building. T}~e new location, as shown on Map 24, Surface Facilities, required excavating approximate) 11,000 Y rerouting Ditch D-4 around the slot excavation or in thaw kpile. The excavated material was either placed in theCeclaim ~unne~ ante rock disposal area. The excavated spoil was sloped to 1H:1 V or steeper depending on field conditions. If field conditions require, a safety bench will be con materia! will not impact the reclamation plan, strutted in the cut slope. Removal of this During construction of the coal stockpile pad and haulroad, a minor northwestern edge of the pad and the haulroad required approximately 20,000 CY of fi ~l App o~mate yu6 p0 CY of fit was required for the remainder of the azea to get the pad to grade. During site preparation, some of the existing fill was removed from this area. Estimates indicate approximately 15,000 CY of material was removed, relative to the existing configuration at the time. Of this volume, a construction proposes and was placed in the waste rock disposal site. Required fill material w pproximately 12,000 CY was not suitable for spoil adjacent to the TCC ports( area. e borrow azea is shown on Map 24. The borrow area was graded level, and thus will provide additional storage area. The sideslopes of the borrow area were reg ceded to 2H• 1 Ve Construction of the reclaim tonne] and laterals required excavating trenches and then constructing the tunnel within the trenches. The tunnel and laterals are constructed of concrete and/or steel. An exhausUescape tunnel extends from the reclaim tunnel. The excavated dirt was used in constmctin constructed where the overland belt exits the reclaim tonne[. A row g the stockpile base. A concrete wall was the borrow area and used as beddin PP mately 100 CY of material was removed from g and packing for Culverts D-2-C and D-2-F, Coal transferred from the stacker tube feed-belt to the stacker tube is stockpiled around the stacker tube. As shown on Map 24, a portion of existia and reclaim tunnel. This required that the haulroad be routed around the north covered u b tunnel and is t and west sides of the coal stockpile. The haulroad profile and typical cross-section aze provided on Map 30A. The stockpiled coal sits ove tithe cecla'm ypically fed b ty Y Y gray to the overland belt b vibratory feeders. As the stockpile increases in size, however, the coal is dozed into the live cone area of the stockpile to facilitate gravity feed to the feeders. Feeders located in the reclaim tunnel feed coal onto the overland belt from the raw coal stockpile. A control building (MCC-1 is constructed adjacent to the reclaim tonne] exhaust fan. This building houses the instrumentation necessary for the reclaim system. The building is approximately 8 x 10 x 10 feet and is constructed on a 6-inch concrete pad and 4 x 10 foot stem wall. The location of the building is shown on Ma 24. building is no longer required, it will be removed.
