In reference to pumping directly to Foidel Creek, TCC will monitor and maintain the Area 1 Pit impoundment as a storage impoundment, with controlled pumping to maintain water levels well below the impoundment crest and inlet of the discharge pipe. In conjunction with elevated spoil spring flows following spring runoff, water levels will be closely monitored and adjusted, as appropriate through controlled pumping to accommodate any significant increases in seasonal spoil spring inflows. By maintaining the water level below the pit discharge level, a buffer is provided for "isolating" water pumped from Site 109 into the pit. The plan is to pump water from Site 109 into the pit and then water would be pumped out of the pit and either recycled to the Prep Plant or discharged directly to Foidel Creek. The pumping rate from the pond will typically exceed that coming from Site 109. The ability to discharge directly into Foidel Creek will be dictated by water quality in Trout Creek and the status of the Fish Creek Borehole. Additional details relative to the Area 1 Pit Temporary Water Storage Basin are provided in Exhibit 8v. Pump installation required the placement of a new transformer, concrete pad, and grounding bed. This installation was in a previously disturbed area; therefore, no topsoil salvage occurred. The pad is approximately 6 feet x 7 feet x 1-foot. A powerline, approximately 350 feet in length, and requiring two power poles, was constructed from an existing line to this new location. The pumping of thickener underflow into the abandoned workings will not have an impact on the active mine operations. The underground pipeline will be monitored inspected as part of the regular weekly mine inspections. The inspections will be conducted to determine if there are any leaks or broken fittings in the line. The permanent monitoring well for this activity is the 10-Right dewatering well which is utilized to pump water from the gob area. The water level in the 10-Right sump is monitored from this location. The stratum underlying the abandoned mine works includes mostly shale and siltstone for 10 feet below the coal seam. The gradient of the proposed settling area ranges from 3.5 to 12 degrees toward the 10-Right dewatering borehole sump. 2.05.4 Reclamation Plan (1) Each anolication shall contain a plan for reclamation of the lands within th~roposed permit area showing how the applicant will comely with environmental protection performance standards of the re ulatory ro am. The elan shall include at a mm~mum all information re wired under the relevant sections of Rule 2 (2) Each plan shall contain the following information for the~roposed permit area: (a) A detailed timetable for the completion of each major step in the reclamation lan; RESPONSE A detailed timetable for the completion of each major step in the Foidel Creek Mine reclamation plan is included as Table 52, Reclamation Time Table. Details concerning the Fish Creek Tipple Reclamation Plan are found within Rule 2.05.4 of the Fish Creek Tipple Appendix, Volume VIII. (b) A detailed estimate of the cost of reclamation of the proposed operations required to be covered by a performance bond with supporting calculations for the estimates; RESPONSE The detailed estimate of reclamation costs of the proposed operations with supporting calculations follows. Time has been rounded to the closest hour and costs have been rounded to the closest dollar. Please see Appendix A, Volume I-B, for all bond calculations for minor, technical, and permit revisions.
