MANAGEMENT <br />~~ <br />JUL 3 0 ~, <br />~'°.~ <br />You had a few comments on Powderhorn's July monthly report. Following are PCC's responses <br />to your concerns: <br />1. CRDA-2 reclamation is progressing. It may be complete by the end of the year and that <br />would indeed be ahead of schedule. <br />2. PCC plans to perform some regrading at CRDA-1 by the end of the year. There are no <br />plans to place "demolition debris" on any of the refuse piles. Excess demolition debris will <br />be placed in the North Portal decline. <br />3. PCC plans to place demolition debris along the east "highwall" near the Roadside coal <br />stacking tube. <br />4. Work required at the RSRDA includes developing two new benches. The refuse material <br />generated by this work will be placed and compacted north of the existing pile. Exhibit 6C <br />shows the upper diversion ditch extends far enough to the north to accommodate the <br />expanded RSRDA pile. <br />5. PCC plans to investigate commercial interest in the South Portal office complex. I <br />recognize any change in land use, AOC variance, etc., would be handled as a technical <br />revision. <br />6. There is a logic problem in the reclamation schedule with regard to the refuse piles. Both <br />CRDA-1 and CRDA-2 are to be reclaimed by the end of 2002. PCC must have at least one <br />pile open to accept coal and refuse material from other reclamation activities. PCC will <br />address this problem in the reclamation schedule by the end of the year. The reclamation <br />schedule for the South Portal office complex will be addressed at the same time. <br />7. I agree the remaining reclamation work involves both structural demolition and a significant <br />amount of earthwork associated with reclamation of the North Portal. <br />Please let me know if you have any questions. <br />Sincerely, <br />'J. E. Stove <br />Consulting Engineer <br />
