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: Structure 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 Crushing Building 54' 27' x 48' Primary Crusher Secondary Crusher Building 42' x 42' x 68.4 Secondary Screen and Crusher Sampler Building 58.8' x 27' x 55.2' Stacking tube Finished Product Stockpile Conveyor Belts Truck Dump Tipple Site Train Loadout Trackage (doesn't include latest extension) Office 48' x 185' x 36' Foundation Concrete footers/ trusses Concrete footers Concrete Concrete Concrete & Crusher Concrete Concrete (Note: Foundations are typically 1- I.5 foot thick concrete slabs with columns) Main ROM Coal Stockade (Located Near Portal) and Stockade Expansion Review of coal handling systems and operations resulted in recognition of the need for increased coal stockpile capacity. In order io provide the required additional capacity, the coal stockpile azea was expanded to fhe north and west in conjunction with site preparation and grading for the Coal Preparation Plant. Expansion requved 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 area, and limited backfilling and grading work to expand the stockpile area. The stockpile expansion azea was gaded so that the base of the pile slopes to the north toward relocated Haul Road B-2. The stockpile expansion azea is shown on Map 24 and required expansion activities aze described under the appropriate section for each of the 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 disturbed; therefore no topsoil remains. Plant growth media recovery, however ,occured for the small azea shown on Map 24, between the existing Pond E embanianent and Haul Road B-2. Up to 4,170 cubic yards of plant growth media was recovered and stockpiled in stockpile (PPSP-2), located to the northeast, from an area 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 runoff and mine water around • the southern side of the coal stockpile area. The ditch, as shown on Map 24, drains into Pond D. Two culverts will be placed in the Ditch D-2 at the locations shown on Map 24. Anew ditch, which has been labeled Ditch E-2, was TRO6-53 2.05-25 05/03/06
