Third Adequacy Letter, Amended CN-01 4 <br />May Day Idaho Mine Complex <br />6. Thank you for the topographic lines provided on Figure'C-3, Topography: July, 2010. <br />Additionally, the color and pattern of line used to delineate the affected land boundary <br />and the permit boundary are sufficiently different to clearly identify the separate <br />boundaries. However, like many maps of the application, Figure C-3 utilized an air <br />photo as a base layer for the map. The details of the air photo interfere with the details <br />provided by the contour lines and elevation numbers. Please eliminate the air photo <br />layer for Figure C-3 to allow clarity in reading the superior detail provided by the <br />contour lines. Please ensure the revised Figure C-3 includes all affected lands within the <br />permit boundary and boundary of affected lands. <br />7. The details of Figure C-7, Man-Made Structures, are difficult to read due to the <br />inappropriate scale (1 inch = 833 feet) resulting from reduction of the map. Figure C-7 <br />fails to include all affected lands within the permit boundary and boundary of affected <br />lands. The color and pattern of line used to delineate the affected land boundary and <br />the permit boundary are sufficiently similar to confuse the two boundaries. Figure C-7 <br />incorrectly indicates two mill facilities on site, one at the Idaho and the second at May <br />Day 1 area. Please submit a new Figure C-7, which corrects these inadequacies. <br />8. Thank you for the topographic lines provided on Figure SWMP-2, Surface Drainage Basin <br />Delineation. Please eliminate the air photo layer for Figure SWMP-2 to allow clarity in <br />reading the superior detail provided by the contour lines. Please ensure the revised <br />Figure SWMP-2 delineates and labels the amended permit boundary and includes all <br />affected lands within the affected land boundary. Figure SWMP-2 inappropriately <br />shows two augmentation ponds, one of which is located outside of the affected land <br />boundary. Figure SWMP-2 inappropriately locates the mill at the Idaho rather than at <br />May Day 1 level. Please submit a revised Figure SWMP-2, which corrects these <br />inadequacies. <br />9. The application for the amended CN-01 included the following reclamation maps: <br />• Figure F-1, May Day No. 1 Post Mine Topography <br />• Figure F-3, May Day No. 2 Post Mine Topography <br />• Figure F-4, Pay Day and Idaho Mill Post Mine Topography <br />• Figure F-4A, Pay Day and Idaho Mill Post Mine Topography Ore Stockpile <br />• Figure F-4, May Day No. 3 Post Mine Topography <br />• Figure F-5a, Chief Portal Post Mine Topography <br />The six reclamation maps submitted with the amended application address <br />approximately 41% of the area addressed by the reclamation plan. Approximately 59% <br />of the area addressed by the reclamation plan is not supported by reclamation maps. <br />Please provide reclamation maps, which satisfy the requirements of Rules 6.2.1(2) and <br />6.4.6, for the following affected lands: <br />0 May Day 1 East - 0.5 acres
