There is an existing truck dump station with a 75-ton capacity steel hopper. . <br />A welded grizzly with 12-inch openings is located above the hopper. A 36- <br />inch belt conveyor used to convey coal from hopper reclaim tunnel to the <br />crusher building. Both the truck dump station and 36-inch wide belt conveyor <br />will be retained as part of the TR-06 modifications. <br />The existing crusher building contains a single-roll crusher. It is a <br />flexible-toothed, hammermill type crusher, driven by an electric motor with <br />fluid coupling drive. The crusher will be removed from the building as part <br />of the TR-06 modifications. <br />There is a conical storage pile, with a conical stake tube immediately to the <br />east of the crusher building. Coal is conveyed from the crusher to the <br />storage pile by an existing 36-inch wide belt conveyor. Coal is reclaimed <br />from storage by four, existing vibratory feeders located beneath the storage <br />pile in a concrete reclaim tunnel. A 60-inch wide reclaim belt conveyor <br />(located in the reclaim tunnel) receives coal from the feeders and discharges <br />to a second 60-inch wide belt conveyor for elevating the coal to the top of <br />the existing train loadout structure. The 36-inch belt conveyor, as well as <br />the conical storage pile, the steel stack tube and stack tube reclaim pile <br />will be demolished as part of the TR-06 modifications. <br />There is an emergency coal storage area adjacent to the truck dump area (see <br />Exhibit 12-2 [Revision 5, dated 8/99]). It is anticipated this storage area <br />will not be needed with the TR-06 modifications. <br />Coal transported to the top of the unit train loadout structure is discharged <br />into a surge bin. Continuous coal sampling is provided by an ASTM sampling <br />system as coal is discharged from the 60-inch wide elevating belt conveyor. <br />The surge bin has a four-foot square, air operated guillotine gate installed <br />horizontally at the bin discharge opening. A telescoping loading chute is <br />provided for uniform loading of train cars and is installed independently and <br />below the guillotine gate. <br />Operation of the existing coal handling equipment is controlled from an <br />operation cab located at the train loadout structure. <br />`.J <br />TR-07 6 Revised 06/06 <br />
