RN07 <br />Page 10 <br />5/30/18 <br /> <br />may be some discrepancy in the naming or labeling of mine facilities between the text and map(s). A summary <br />table (Table 49b) has been developed listing the existing mine facilities and their locations. In addition, the <br />referenced facilities text description and corresponding map(s) have been reviewed and any naming/labeling <br />discrepancies addressed. The updated permit materials accompany these responses for replacement in the PAP. <br /> <br />Resolved <br /> <br />30. The Division has six different maps in the Map 24 series. The numbering/titles of the maps conflict and there <br />is significant overlapping between the maps. Many of the labels on these maps are too small to read. The Map <br />24 series maps need to be updated and consolidated. Please create new maps that depict the surface facilities, <br />freshwater system, roads, pipelines, exploration corehole locations, etc. Please consolidate to a minimum <br />number of maps that meet the requirements of Rule 2.10. Please insure these maps are titled/numbered in a <br />logical fashion. Each facility needs to have a label that is legible and matches the title of the facility discussed <br />in section 2.05.3(3) of the permit. <br /> <br />Response: - The approved Map 24 series (Surface Facilities and Freshwater Systems) currently consists of four <br />map sheets, which show different areas of the Mine property. Given that the Mine Permit Area encompasses <br />roughly 40 square miles, map formatting attempts to balance coverage area and detail, while limiting map sheet <br />overall size. Map formatting and labeling have been reviewed, the Map 24 series has been revised to address the <br />noted concerns, and the revised maps accompany these responses for replacement in the PAP. <br /> <br />Resolved <br /> <br />31. Page 2.05-23 cites the Fuel Storage and Fueling Installation Upgrades designs are located in Exhibit 49U. <br />The exhibit cited should be Exhibit 49V. Please revise this page accordingly. <br /> <br />Response: - The referenced exhibit reference has been corrected and copies of the revised page accompany these <br />responses for replacement in the PAP. <br /> <br />Resolved <br /> <br />32. The Division could not locate the 19RT Borehole discussed on Page 2.05-50 of the Permit, nor could it ascertain <br />how water is transferred to the 6MN Reservoir from this borehole. Please clarify this and update the <br />appropriate Map 24 series maps to depict the borehole and any necessary water lines. Please update Map 16 <br />as well to show these features. <br /> <br />Response: - The proposed 19-Right Dewatering Borehole and Pipeline were permitted under TR10-73, but have <br />not yet been constructed. The borehole and pipeline locations were shown on a revision to Map 24 (Sheet 3 of 3) <br />that accompanied the revision application. The previously referenced revisions to the Map 24 series (Comments <br />29 and 30) include clear labeling of the proposed 19-Right Borehole and Pipeline. Map 16 was deleted as redundant, <br />with PR92-02. <br /> <br />Resolved <br /> <br />33. The Division could not locate the Trout Creek Sandstone Test holes (WT98001 and WT98002) discussed on <br />Page 2.05-65.1 of the Permit. Please clarify this and update the appropriate Map 24 series maps to depict <br />these boreholes.
