Map 24. The trenches were dug with a backhoe or trackhoe. During the excavation process, suitable plant <br />growth media was removed and windrowed adjacent to the Vench, and then replaced on top of the subsoils <br />resumed to the Vench. <br />In reference to pumping directly to Foidel Creek, TCC will monitor and maintain the Area 1 Pit <br />impoundment as a storage impoundment, with controlled pumping to maintain water levels well below the <br />impoundment crest and inlet of the discharge pipe. In conjunction with elevated spoil spring flows <br />following spring runoff, water levels will be closely monitored and adjusted, as appropriate through <br />controlled pumping to accommodate any significant increases in seasonal spoil spring inflows. By <br />maintaining the water level below the pit dischazge level, a buffer is provided for "isolating" water pumped <br />from Site 109 into the pit. The plan is to pump water from Site 109 into the pit and then water would be <br />pumped out of the pit and either recycled to the Prep Plant or discharged directly to Foidel Creek. The <br />pumping rate from the pond will typically exceed that coming from Site ]09. The ability to dischazge <br />directly into Foidel Creek will be dictated by water quality in Trout Creek and the status of the Fish Creek <br />Borehole. Additional details relative to the Area 1 Pit Temporary Water Storage Basin aze provided in <br />Exhibit SV. <br />Pump installation required the placement of a new transformer, concrete pad, and grounding-bed. This <br />installation was in a previously disturbed area; therefore, no topsoil salvage occurred. The pad is <br />approximately 6 x 7 x 1 foot. A powerline, approximately 350 feet in length, and requiring two power <br />poles, was constructed from an existing line to this new location. The pumping of thickener underflow into <br />the abandoned workings will not have an impact on the active mine operations. The underground pipeline <br />will be monitored/inspected as pan of the regular weekly mine inspections. The inspections will be <br />conducted to determine if there are any leaks or broken fittings in the line. <br />The permanent monitoring well for this activity is the ]0-Right dewatering well which is utilized to pump <br />water from the gob azea. The water level in the 10-Right stunp is monitored from this location. The <br />stratum underlying the abandoned mine works includes mostly shale and siltstone for ]0 feet below the <br />coal seam. The gradient of the proposed settling azea ranges from 3.5 to 12 degrees towazd the 10-Right <br />dewatering borehole sump. <br />2.05.4 Reclamation Plan <br />(I l Each application shall contain~lan for reclamation of the lands within the proposed pemtit azea, <br />showine how the applicant will comply with environmental protection Rerformance standazds of the regulatory <br />proeram.
