Supporting documentation can be found in Tab 08. <br /> 2.04.9(1)-(3) Soils Information <br /> No adequacy review issues noted. The information required by this rule is discussed in section 2.04.9 of the <br /> permit and the supporting data and maps are located in Tab 09 Exhibit 9-1, 9-3, and Tab 09. Exhibit 9-2 has been <br /> removed from the permit file. <br /> 2.04.10(1)-(5)Vegetation Information <br /> No adequacy review issues noted. Supporting maps and data are located in Tab 10, Exhibit 10-1, 10-3, appendix <br /> 10-1 through 10-10. Exhibit 10-2 has been removed from the permit file <br /> 2.04.11 (1)-(4)Fish and Wildlife Information <br /> No adequacy review comments. The Threatened and Endangered species discussed in the permit are accurate and <br /> up to date. Supporting documentation and data can be found in Tab 11, Tab Appendix 11-1, and Exhibit's 11-1 <br /> through 11-3. <br /> 2.04.12 Prime Farmland Investigation <br /> No adequacy review issues noted. Supporting documentation can be found in Tab 04. <br /> 2.05.4 (2)(b)—Reclamation Cost Estimate <br /> I have conducted a reclamation cost estimate for the site and found that the liability to reclaim the Yoast Mine to <br /> be $4,499,918.00. The required surety and currently held surety is $3,790,697.28. Given this, the bond held is <br /> not adequate at this time. Attached is a copy of the reclamation cost estimate conducted, it includes a Cost <br /> Summary, Task Summary and CIRCES task sheets. The cost increase is largely due to the fact that the previous <br /> cost estimate used for Midterm 07 was not updated at the time. Please let me know if you or the operator have <br /> questions. <br /> OF CplO <br /> 1313 Sherman Street, Room 215, Denver,CO 80203 P 303.866.3567 F 303.832.8106 .state.co.us htt ://minin Q <br /> P g �� : \90 <br /> Jared Polis,Governor I Dan Gibbs, Executive Director I Virginia Brannon, Director <br /> r <br /> 1876 <br />
