Hickenlooper <br />Governor <br />Mike King <br />Executive Director <br />Loretta E. Piheda <br />Director <br />The Division has conducted additional review of the permit application for the New Horizon <br />North Mine, concentrating mainly on surface water monitoring and the Probable Hydrologic <br />Consequences aspects. The following are new adequacy review questions and comments, which <br />are numbered in sequence with earlier adequacy items, listed by section and subsection: <br />kall <br />2.04.7 (2) — .Surface Water Information <br />13. In Table 2.04.7-5 on page 17 of Section 2.04.7, surface water monitoring station SW-N205 <br />is described as being inflow for Glasier Draw. However, referring to the topographic contour <br />lines on Map 2.04.7-1, it appears that runoff from this site would flow southwest into <br />Meehan Draw, rather than into Glasier Draw. Please explain. <br />14. In the last full paragraph on page 23 of Section 2.04.7, reference is made to pond NHN-001 <br />and ponds NHN-002 through NHN-004. Please revise this text to show that there are three <br />ponds. <br />15. In several instances in the permit application, reference is made to baseline surface water <br />hydrology data being located in the New Horizon 1 Area and the New Horizon 2 Area <br />permit applications. Please include all baseline information relevant to the proposed New <br />Horizon North Mine in the New Horizon North Mine permit application. <br />16. In the top paragraph on page 18 of Section 2.04.7, potential uses of water for domestic <br />drinking, irrigation and livestock are mentioned. Please expand the discussion to include, <br />and reference, the applicable surface water quality standards, if any, from the CDPHE. <br />Office of Office of <br />Mined Land Reclamation Denver • Grand junction • Durango Active and Inactive Mines <br />
