In reference to pumping directly into Foidel Creek, TCC will monitor and maintain the Area 1 Pit <br />impoundment as a storage impoundment, with controlled ptunping to maintain water levels well below the <br />impoundment crest and inlet of the dischazge 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 discharge 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 into Foidel Creek. The <br />pumping rate from the pond will typically exceed that coming from Site 109. The ability to dischazge <br />duectly 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 are provided in <br />Exhibit 8v. <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 salvaging occurred. The pad is <br />approximately 6 feet x 7 feet x 1-foot. A powerline, approximately 350 feet in length, and requiring two <br />power poles, was constructed from an existing line to this new location. The pumping of thickener <br />underflow into the abandoned workings will not have an impact on the active mine operations. The <br />underground pipeline will be monitored/inspected as part of the regular weekly mine inspections. The <br />inspections will be conducted to determine if there are any leaks or broken fittings in the line. <br />The permanent monitoring well for this activity is the 10-Right dewatering well which is utilized to pump <br />water from the gob area. The water level in the 10-Right sump is monitored from this location. The <br />stratum underlying the abandoned mine works includes mostly shale and siltstone for 10 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 />Each application shall contain a plan for reclamation of the lands within the prooosed_permit area, <br />showin¢ how the applicant will comply with environmental protection performance standards of the re ug latory <br />prokram. The plan shall include. at a minimum all information required under the relevant sections of Ru]e 2. <br />(2) Each plan shall contain the following information for the oronosed pemut area: <br />(a) A detailed timetable for the completion of each major stew in the reclamation Alan; <br />RESPONSE <br />A detailed timetable for the completion of each major step in the Foidel Creek Mine reclamation plan is <br />included as Table 52, Reclamation Time Table. Details concerning the Fish Creek Tipple Reclamation <br />Plan are found within Rule 2.05.4 of the Fish Creek Tipple Appendix, Volume VIII. <br />(bY A detailed estimate of the cost of reclamation of the nrooosed operations required to be <br />covered by a nerlorniance bond with supporine calculations for the estimates; <br />RESPONSE <br />The detailed estimate of reclamation costs of the proposed operations with supporting calculations follows. <br />Time has been rounded to the closest hour and costs have been rounded to the closest dollaz. Please see <br />Appendix A, Volume I-B, for all bond calculations for minor, technical, and permit revisions. <br />TR 05-47 2.05-98 Revised - Apri14, 2005 <br />
