that intercepted ground water was sealed using a grout plug in the aquifer zone and then backfilled to the surface <br /> with cuttings. <br /> 411) The support bents for the BOB Conveyor are of typical steel construction, with the further-most bent being of 4-leg <br /> construction, while the inner bents are of 2-leg construction. The 4-leg bent has been designed for a revetment <br /> enclosure, in the event TCC should decide that this bent (constructed similar to the MR93-93 revetment framing) <br /> requires a protective covering at some future time (the bond calculation reflects the revetment enclosure). These <br /> bents are supported by 48-inch diameter concrete piers extending approximately 25 feet to bedrock. These piers are <br /> connected by grade beams (footers) approximately 1 x 4 x 18 feet to form the foundations. The drive structure, of <br /> steel-frame construction, is elevated on four 3-inch diameter piers which extend approximately 25 feet to bedrock. <br /> 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 concrete slab <br /> constructed over 1 x 4 foot foundation footers. Soil was removed for pier construction using an auger rig or by <br /> excavating with a backhoe or similar piece of equipment. The balance of the remaining site prep was completed <br /> using a small dozer or backhoe. Subsoil removed for the installation of the piers, footer, and slabs was used to <br /> backfill around the piers and footers, or was spread-out,depending on the situation. <br /> The BOB Conveyor and associated structures are constructed within a previously disturbed area, with drainage <br /> from this area controlled by the existing drainage control system. As such, no topsoil recovery occurred and no <br /> 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 structure were constructed on the west <br /> side of the Secondary Crusher Building for the main 48-inch belt structure. 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 /> BOB 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. A ramp was built-up to accommodate loading <br /> • of the cars. The site is approximately 150 x 300 x 6 feet. Approximately 10,000 CY was excavated from the site, <br /> with some of the excavated material placed east of the site near the railroad tunnel and road, allowing for improved <br /> drainage from this area. The drainage from this area will <br /> III <br /> TR11-77 2.05-33 07/20/11 <br />
