Third Adequacy Letter, Amended CN-01 5 May Day Idaho Mine Complex • Augmentation Pipeline Corridor - • La Plata Bridge - • Staging Yard - • Exploration Roads and Exploration Drill Pads - • Pre-existing Roads - • New Access Road - 0.4 acres 0.1 acres 1.0 acres 15.8 acres 9.5 acres 1.8 acres 10. The six reclamation maps submitted with the amended application show only portions of the affected lands referenced by the map title, do not delineate or label the boundary of affected lands, and conflict with the text of the reclamation plan. Please correct these inadequacies by revising the reclamation maps as follows: The reclamation maps must show the expected physical appearance of all affected lands after reclamation has been completed. All portions of the 47.6 acres of affected lands must be shown on the reclamation maps. b. The reclamation maps must delineate and label the boundaries of affected land. If a portion of the permit boundary is located within the area shown on the reclamation map, please show the portion of the permit boundary as well. c. Please illustrate the transition of reclaimed areas with the natural topography by extending the contour lines beyond the boundary of affected lands. d. The reclamation maps must illustrate and clarify the reclamation plan; conflict between the reclamation maps and the reclamation plan are not acceptable. Examples of conflict between the reclamation plan and reclamation maps, and/or inadequacies of the reclamation maps, are provided below: • Figure F-1 indicates a Filter Press, a 35 ton Dry Cake Hopper, a portal shed, and portions of the Mill will remain at the May Day 1 level as permanent structures. The reclamation plan does not represent these structures as permanent. Therefore, Figure F-1 is in conflict with the reclamation plan. • Figure F-1 indicates a 20 foot highwall at 0.2H:1V, and a 35 foot highwall at 0.8H:1V. The near-vertical slopes are in conflict with the reclamation plan, which indicates these slopes will be reduced to 1.5H:1V. • Figure F-3 indicates a 30 foot highwall at 0.5H:1V, which is in conflict with the 1.5H:1V slope described in reclamation plan. • Figure F-3 shows two sheds as permanent structures, not addressed by the reclamation plan. • Figures F-4 and F-4A show several access roads which are not indicated by the reclamation contour lines. If the access roads are permanent please alter the contour lines to indicate such. If the access roads are not permanent please remove them from the reclamation maps.
