waterline. The section of the dischazge or suction line that is exposed to the air may be insulated to prevent freezing. The building will be constructed on the concrete slab to house the pump and controls for the pumping system. The concrete slab (approximately 12 x 20 x 2 feet) will be constructed on the existing berm, with limited fill to establish a stable pad for slab construction. The fill will be placed on the west side of the existing cell embankment. The fill material will be obtained from within the boundary of the disturbed site or brought in from the portal area. Once the new building is constructed, the building housing the acid-feed system will be de-energized and, if not required for additional storage, removed from the location. The power-feed from the existing substation will be extended to the pump-station. Extension of the powerline will require the installation of two additional powerpoles. All of the proposed construction activities will occur within the previously disturbed area. The waterline will be installed along the existing road corridor, except for that segment which traverses the reclaimed and bond-released surface mine area. In areas where the waterline will be installed in the road corridor, the trench will be excavated either down the center of the road or along the shoulder. Field conditions will dictate the location of the trench excavation. The segment of the line which traverses the former surface mine area will require that the available topsoil be salvaged and then replaced on the trench excavation. For this segment, topsoil will be salvaged and placed to one side of the trench and subsoil excavated and placed on other side of trench, the waterline will be bedded and placed in the trench, the trench will be backfilled with subsoil, then topsoil will be replaced over footprint of trench and the area broadcast seeded with an approved seed mixture. At both the Escape Shaft and 10-Right waterline, a manifold and valuing or similar device will be installed to connect the waterline with each of the structures at these locations. Both of these locations are in previously disturbed azeas. A valve will be installed in the waterline from the Fish Creek Borehole to direct the water to either the Escape Shag or the 10-Right waterline. The water will enter the underground water system and be delivered to the appropriate mine location. The existing powerline will be tapped into to provide power to the location. Two additional powerpoles will be installed, one approximately midway between the existing line and the pad. The other pole will installed within the boundary of the Escape Shaft pad. Up to five manholes will be located along the waterline, with installed "T's" to provide taps for setting up feeder- lines to deliver water to stock tanks. All of the installations will be of similar construction, with a 5-foot diameter culvert with insulated lid for the manhole access, and a valve and "T"-connection to the waterline. Any feeder line will run overland from the manhole to a stock tank and the water will be used for stock watering. Afloat device, or other type of control, will be installed at the stock tank to control flows to the tank. The locations of the manholes will be deternuned in the field based on topography and stock water distribution needs. A utility building, approximately 10 x 10 x 10 feet will be installed over or immediately adjacent to the Escape Shaft. The building will be placed on a concrete slab approximately 10 x lOx 1 feet. When the building is no longer required, or at the time of final reclamation, it will be removed from the site. Overland Belt Magnet (MR02-1791 Twentymile will install a magnet over the overland belt to pick tramp metal from the coal stream prior to it entering the primary crusher. The captured metal will drop from the magnet to a bin located underneath it for recycling or disposal. The magnet is in a framework constructed over the belt, and a trolley system on the framework moves the magnet in and out of position over the belt. The frame work is constructed of H-beam which is anchored to six rebar-reinforced concrete piers drilled to bedrock. The piers are two feet in diameter, extend from 6 to 9 feet into bedrock and will extend three feet above grade. A concrete pad approximately 8 x 10 x 2 feet will be constructed under the bin to facilitate removal. The framework and pad will be constructed in a previously disturbed area. i TROS-51 2.05-65.4 03/13/06
