70 x 10 x 0.5 foot platform truck scale located north of the Mine Office. The scale is mounted in a 90 x 12 x 5 x 1 <br />thick concrete vault. A buried 50' long 110 v. conduit provides power. <br />• The coal is conveyed from the Secondary Crusher Building into the Sampler Building, where it passes through the <br />sampling unit. The coal then transfers to the stacker tube belt which moves it to the stacker tube, located at the <br />furished product (or Batch-Weigh Loadout Stockpile). The coal discharges from the stacker tube through a series <br />of doors and forms a conical product stockpile azound the stacking tube. Originally, the stockpiled coal was fed by <br />gravity through feeders to the train loading facility. During loading, the train would back through the tunnel under <br />the stockpile to load, with loaded cazs following the tail-track around Pinnacle Peak. The location of the track is <br />shown on Map 24. The new Batch-Weigh Loadout replaced this system and, while the system components are still <br />in-place, they are not currently utilized. <br />The coal handling system was modified to incorporate construction of a conveyor belt (belt-out-back), drive <br />structwe, belt take-up, and control building to move coal from the Secondary Crusher Building to the secondary <br />ROM Coal Stockpile neaz the tipple. The locations of the belt, drive structwe, and control building are shown on <br />Map 24 (Surface Facilities). <br />TCC drilled a limited number of shallow holes in the area of the Tipple to provide foundation information for final <br />design of the belt-out-back. A total of approximately seven 4-inch diameter holes were drilled, radiating from a <br />point adjacent to the Secondary Crusher Building outward to the secondary ROM Stockpile. An auger rig was used <br />to drill the holes, which varied in depth from 20 to 60 feet. The holes were drilled within the previously disturbed <br />azea, and if no ground water was intercepted, the holes were backfilled with the cuttings from the hole. Any hole <br />that intercepted ground water was sealed using a grout plug in the aquifer zone and then backfilled to the surface <br />with cuttings. <br />The support bents for the belt-out-back conveyor are of typical steel construction, with the further-most bent being <br />of 4-leg construction, while the inner bent aze of 2-leg construction. The 4-leg bent has been designed for a <br />• revetment enclosure, in the event TCC should decide that this bent (constructed similaz to the MR 93-93 revetment <br />framing) requires a protective covering at some futwe time (the bond calculation reflects the revetment encloswe). <br />These bents are supported by 48-inch diameter concrete piers extending approximately 25 feet to bedrock. These <br />piers are connected by grade beams (footers) approximately 1 x 4 x 18 feet to form the foundations. The drive <br />structwe of steel frame construction, elevated on fow 3-inch" diameter piers which extend approximately 25 feet to <br />bedrock. The 12 x 16 x 10 foot MCC building is of typical metal construction, and sets on a 12 x 16 x 0.5 foot <br />concrete slab constructed over 1 x 4 foot foundation footers. Soil was removed for pier construction using an auger <br />rig or by excavating with a backhoe or similaz piece of equipment. The balance of the remaining site prep was <br />completed using a small dozer or backhoe. Subsoil removed for the installation of the piers, footer, and slabs was <br />used to backfill azound the piers and footers, or was spread out depending on the situation. <br />The belt-out-back conveyor and associated structures aze constructed within a previously disturbed azea, with <br />drainage from this azea controlled by the existing drainage control system. As such, no topsoil recovery occurred <br />and no significant drainage modifications will be required. The conveyor tailpiece was mounted within the existing <br />Secondary Crusher Building, and two support bents and an elevated drive structwe were constructed on the west <br />side of the Secondary Crusher Building for the main 48-inch belt structwe. An additional concrete support slab, <br />immediately adjacent to the east wall of the Secondary Crusher Building, may be necessary for the belt take-up. <br />TCC has included the costs for this additional slab in the associated bond calculations. Power is supplied to the <br />belt-out-back conveyor from the substation east of the Tipple over to the MCC building. <br />CYCC's Loadout site was constructed within the disturbed area between the processing facilities and the railroad <br />tracks. The site was excavated down to the elevation of the tracks. If needed, a ramp will be built-up to <br />accommodate loading of the cars. The site will be approximately 150 x 300 x 6 feet. It is anticipated that about <br />10,000 CY will be excavated from the site. Some of the excavated material will be placed east of the site neaz the <br />• railroad tunnel and road. This will allow for improved drainage from this area. The drainage from this azea will <br />TR06-53 2.05-33 05/03/06 <br />
