The tipple/loadout facilities include the Run-of--Mine (ROM or "Belt-Out-Back") stockpile, truck dump, crushing facilities (primary & secondary), conveying facilities, sampling facilities, finished product (Tipple) stockpile, stoker belt and dump, stoker product stockpile, conveyor belt and stacker for coal stockpile, train loadout, and trackage, and access and temporary storage site for cleaning spilled coal from loadout tunnel. Of the above structures (as discussed in the following sections), the following are identified as existing structures, transferred from Permit C- 81-071: Stmcture Dimension (LxWxH) Raw Coal Conveyor 126' x 10'(dia) ROM Coal Conveyor 168' x 10'(dia) ROM Coal Stockpile (doesn't include latest expansion area) Reclaim Tunnel 537' x 20'(dia) Primary Crashing Building 54' 27' x 48' Primary Crasher Secondary Crusher Building Secondary Screen and Crusher Sampler Building Stacking tube Finished Product Stockpile Conveyor Belts Truck Dump Tipple Site Train Loadout 42' x 42' x 68.4 58.8' x 27' x 55.2' Foundation Concrete footers/ trusses Concrete footers Concrete Concrete Concrete & Crusher Concrete Trackage (doesn't include latest extension) Office 48' x 185' x 36' Concrete • (Note: Foundations aze typically 1- 1.5 foot thick concrete slabs with columns) Main ROM Coal Stockpile (Located Near Portal) and Stockpile Expansion Review of coal handling systems and operations resulted in recognition of the need for increased coal stockpile capacity. In order to provide the required additional capacity, the coal stockpile area was expanded to the north and west in conjunction with site preparation and grading for the Coal Preparation Plant. Expansion required relocation and reconstruction of Pond E and the associated ditches, elimination of the segment of haul road which traversed the north edge of the stockpile azea, and limited backfilling and grading work to expand the stockpile azea. The stockpile expansion azea was graded so that the base of the pile slopes to the north towazd relocated Haul Road B-2. The stockpile expansion area is shown on Map 24, and required expansion activities aze described under the appropriate section for each ofthe effected facilities. The stockpile expansion increased total capacity for the main stockpile area to approximately 600,000 tons. Most of the azea affected by the ROM stockpile expansion, was previously distwbed; therefore no topsoil remains. Plant growth media recovery, however, occurred for the small azea shown on Map 24, between the existing Pond E embankment and Haul Road B-2. Up to 4,170 cubic yazds of plant growth media was recovered and stockpiled in stockpile (PPSP-2), located to the northeast, from an azea approximately 752 x 100 feet (recovery depth approximately 1.5 feet). The reconstruction of Pond E required the removal of approximately 9,300 CY of topsoil from an azea approximately 150 x 7,210 feet, with an average soil recovery depth of approximately 28 inches. Approximately 3,000 CY of the topsoil was placed in Stockpile SF-4, while the remaining 6,300 CY was placed in Stockpile PPSP-1. Table 49a was revised to reflect these topsoil salvage and stockpile volumes. The existing drainage control plan was slightly modified to control drainage from the expanded coal stockpile, as shown on Map 24. The modifications included rerouting Ditch D-2 so that it carries ranoff and mine water azound the southern side of the coal stockpile area. The ditch, as shown on Map 24, drains into Pond D.
