Mr. Wallace H. Erickson Response to Sixth Adequacy October 11, 2011 Page 8 survey map prepared by Mountain Man Surveying in place of the August 2009 Survey in Exhibit O. Wildcat is also submitting a revised Exhibit 0-1. See Ex. 3. Adequacy Issue No. 5. Figure C -3, Existing Topography, fails to show the existing topography. At 5- foot contour interval, the existing highwalls, mine benches, and cut and fill slopes of the access roads should be evident by the contour lines, but they are not. The existing highwalls and mine benches are clearly evident by the 5 -foot contour lines on Figures D1, D -1 of Attachment D -2, D -1 of Attachment D -3, 0 -1 of Attachment 0 -4, 0 -1 of Attachment 0 -6, D -2 of Attachment D -2, and D2 of Attachment D -6. Rather than existing topography, Figure C -3 appears to show a conceptual topography and does not reflect the detailed topography typically expected from a 5 -foot contour interval. Please provide the basis for the topographic information displayed on Figure C -3. Since Figure C -3 must be revised to address issue 4 above, please rename the revised Figure C -3 to more accurately represent the conceptual nature of the displayed information. Response to Adequacy Issue No. 5. The topographic information displayed on Figure C -3 is taken from an existing USGS map. It is the best topographic information available. Wildcat is submitting a revised Figure C -3 indicating in the title block that the data is USGS data See Ex. 4. Adequacy Issue No. 6. Figure F -1, May Day 1 Reclamation Topography, indicates the near - vertical highwall will be reclaimed to 2H:1 V slope. Preliminary calculations indicate the quantity of backfill necessary to achieve the 2H:1V slope approach 15,000 cubic yards. The Reclamation Plan does not clarify the method of slope reduction. Figure F -1 does not identify any borrow locations for the backfill material. Please identify the locations of the borrow areas for the backfill material. Please clarify the method of highwall reduction to be utilized at the May Day 1, 2 and 3 areas, and at the Chief Portal. Response to Adequacy Issue No. 6. Wildcat will modify Exhibit E to clarify the method of highwall reduction it will use at the May Day No. 1, No. 2 and No. 3 areas, and at the Chief Portal, will be balanced cut and fill. To make this clarification, Wildcat will add the following sentences to the beginning of the last paragraph on Page 3 of Exhibit E: "Wildcat will reclaim the highwalls at May Day No. 1, May Day No. 2, May Day No. 3 and the Chief Portal using a balanced cut and fill method. Wildcat will pull material back from the bench at these locations upslope to form the final grade. In the case of May Day No. 1, additional material may be taken from the fill slope or the slope above the highwall to form the final grade" Wildcat is submitting revised Figures F -3 and F -5A reflecting this DEN 97,629,117v1 10 -11 -11 GREENBERG TRAURIG, LLP ® ATTORNEYS AT LAW ® WWW.GTLAW.COM
