Dear Mr. Wilcox, I have reviewed the materials submitted by you toward satisfying the adequacy requirements of the above-named application. There have been several submittals from you since my IasC review letter, all of which have been taken into account in this review letter. Many of the outstanding adequacy items have been addressed, though there are still some questions. 1 have included those questions so that you may respond to them, and have included some comments which do not require any response. Please understand that your responses are important for ensuring that areas of monitoring are clarified, that physical parameters and disturbances are quantified, and that the best representative bond amount may be calculated. As usual, I have listed these items in the order of the exhibit to which they pertain. Please artange your responses in similar order. Exhibit C - Minin¢ Plan Map Your proposed mining plan was recently revised to mine in two phases, with the mining plans being dramatically different for the two phases. When you submitted this recent proposed revision, you did not include a Phase I mining plan map, to accompany the narrative. I will again request that you submit a revised map, which adequately depicts all aspects of the revision involving Phase I operations, as listed below. Your recent submittal includes a copy of a fared snap showing a few details of the approximately hvo new acres of Phase [, but the map does not suffice for this exhibit. Please review Rule 6.4.3, and provide a Phase I mining map including all required information. Also, please ensure that this map is not derived from a faxed copy, since faxing is known to distort map dimensions. Details should include roads, slopes, stockpile areas for product and topsail, direction of mining, floor configuration, drainage patterns, cultural resource area, and map scale or boundary measurements. All previous submittals of mining plan maps are adequate for depicting the Phase II plan. E.ehibit D - Minine Plan Your last submittal clearly states that Phase I will consist of operating in the existing area and in an additional hvo acres (+/-) to be mined similarly to the existing 1 10 permit area. All operations beyond that area should be considered Phase Il, and may include additional impacts to the Phase 1 area. Phase II is recognized to be the original plan. Will any final reclamation activities occur during the operating of Phase I, before i[ is known whether Phase I1 will be approved'?
