eliminated which will reduce ground water flow A statement to this effect has been <br />added in the text. Seepages 14 and 16. <br />12. On page 13, WFC describes 30 ground water rights (wells) that have been identified; <br />however, this conflicts with the information presented earlier in Section 2.04.7. Under the <br />Present Groundwater Use section (page 11 and Table 2.04.7.4 of Section 2.04.7) WFC states <br />that thirty four wells were identified. Please clarify this discrepancy. <br />Response - The discrepancy has been corrected in the text. Seepage 14. <br />13. Please provide an estimate of flow and TDS concentrations for all potential future spoil <br />springs. Provide the predicted locations for all future spoil springs to Meehan Draw and <br />Tuttle Draw and clearly label them on an appropriate map. <br />Response - See Map 2.04.7-1 SS#1 and SS#4, added text on pages 26, 27, 28 and Table <br />2.05.6(3)-2. <br />14. Section 3), Impact of Spoil Material on Groundwater Flow and Recharge, beginning on page <br />14 again minimally discusses springs tributary to Tuttle Draw and springs tributary to <br />Meehan Draw. The discussion for Tuttle Draw should clearly identify what the predicted <br />flow and TDS concentrations will be for the future spoil springs that may occur. Sections 3 <br />and 5 of the PHC (pages 14 through 22) need to be updated accordingly with predicted TDS <br />and flow rate information for springs tributary to Meehan Draw and any impacts to Coal <br />creek Canyon. <br />Response - See Table 2.05.6(3)-1 and See Map 2.04.7-1 SS#1 and SS#4, added text on <br />pages 26,27,28 and Table 2.05.6(3)-2. <br />15. On page 17 it would be appropriate to add a description and prediction of the combined <br />effect of discharge that may occur from the new NHN Mine mixing with the "old Backfill" <br />(New Horizon #1 Area) and ultimately discharging from the approximate location of Spoil <br />Spring #1. Please provide the cumulative prediction for the existing flow from SS#1 when it <br />is combined with the additional TDS concentration and flow from the proposed NHN Mine <br />Area backfill. <br />Response - The sections have been revised as suggested Seepages 19 through 28 and <br />Table 2.05.6(3)-2. <br />16. On page 19 WFC indicates that during mining the overburden will be tested and if acidic <br />layers are encountered, they will be mixed with non-acidic layers. How will it be <br />determined that acidic layers are encountered? Please provide details on how the <br />overburden will be tested and include the sampling and analysis plan in the application <br />package. (This question is related to Item 6 of Section 2.04.6(2) in Part 1 of the PAR.) <br />Response - Three new overburden sampling holes have been drilled to provide additional <br />information. However, acidic layers will be dark brown to black in color and will be <br />below the zone of weathering and oxidation. Text carried over from New Horizon permit <br />text has been deleted <br />17. On page 23 in the first paragraph under 6) Impact of Backfill Water Quality on Surface <br />Water Quality WFC states that the NHN spoil spring will issue to a tributary of Tuttle Draw. <br />Response to First Adequacy Review Page 48
