C- 2010 -089 PAR Part 2 5 -Jan -2011 <br />New Horizon North Mine Page, 11 of 13 <br />Please cross reference this to a location on an appropriate map and add a similar discussion <br />for spoil spring(s) that may issue to Meehan Draw with cross reference to its location on a <br />map. <br />18. On page 24 under Impacts to Receiving Waters add a description and pertinent information <br />on spoil spring discharge to Meehan Draw and what the overall impact if any will be to Coal <br />Creek Canyon and ultimately the San Miguel River. <br />19. In the third paragraph of page 25, WFC states that quarterly samples will be collected and <br />analyzed for the quality parameters as advised by DRMS. The list of parameters should <br />clearly be identified and included in the approved water monitoring plan. Please revise this <br />statement accordingly and propose a list of parameters at this time for DRMS approval. <br />20. At the conclusion of Section 6) Impact of Backfill Water Quality on Surface Water Quality <br />it would be appropriate to discuss the cumulative impact of Spoil Spring #1 discharge plus <br />that from NHN Mine Area. Please provide a summary of cumulative impacts resulting from <br />the combined discharge from SS #1 and that from NHN Mine, if deemed appropriate. <br />21. Please update Table 2.05.6(3) -2 on page 26 with predicted impacts for NHN Mine backfill <br />discharge to Meehan Draw and Coal Creek Canyon. If the predicted impacts (from <br />Meehan/Coal Canyon) change the predicted San Miguel River quality then update the table <br />accordingly. <br />22. In Appendix 2.05.6(3) -2, Table 2.05.6(3) -2a lists the "Consequences of the Life -of Mine <br />Mining Plan for the New Horizon Mining Area ". In Item 5 Impact of spoil water quality on <br />ground and surface water quality add a discussion of the analysis results and the significance <br />for the predicted spoil spring discharge to Meehan Draw and the overall impact this has on <br />Coal Creek Canyon and the San Miguel River. Add a discussion of the cumulative effect to <br />the San Miguel River from spoil spring discharges to both Tuttle Draw and Meehan Draw. <br />23. In Section 2.05.6(3)(b)(v) NHN Hydrologic Reclamation Plan, WFC states that "...no <br />special handling of materials is anticipated for mining operations conducted." The Division <br />understands that there will be special handling of materials including separation of suitable <br />versus un- suitable materials as described in earlier sections of the application. Please clarify <br />this discrepancy and revise this section accordingly. (This question is related to Item 6 of <br />Section 2.04.6(2) in Part 1 of the PAR.) <br />24. A few typographical errors were note on the following pages of Section 2.05.6(3). On page <br />14 in the last paragraph, the statement "...GW -N8 has recovered aboul0 ft..." needs to be <br />corrected. On page 23 the first sentence of the last paragraph "...these slightly elevated <br />level of TDS..." level should be changed to plural "...levels..." On page 24 in the last <br />sentence of the second paragraph "...will every reach..." should be changed to "...ever <br />reach..." <br />2.06 - REQUIREMENTS FOR PERMITS FOR SPECIAL CATEGORIES OF MINING <br />2.06.8 Surface Coal Mining and Reclamation Operations on Areas, or Adjacent to Areas, <br />Including Alluvial Valley Floors. <br />
