(Colowyo),the Division has the following comments: <br /> 1. On the proposed Table of Contents,List of Maps,page x,it lists Map 23A Mine Plan—South Taylor.However,per the <br /> provided Colowyo Mine"change sheet",Map 23A is being requested for removal as it has been incorporated into Map <br /> 23.Please provide an updated List of Maps,page x. <br /> 2. On the proposed List of Maps, there appears to be a.typo with Map 29 "Spoil Grading tTiming". Please provide an <br /> updated List of Maps. <br /> 3. The proposed Volume 12,Rule 2,page 66 does not flow properly into the currently approved pages.The final paragraph <br /> for proposed page 66 is the first paragraph of the currently approved page 67. Volume 12, Rule 2, page 66 was last <br /> approved with Colowyo Mine MR-220.Please provide an updated Volume 12,Rule 2,page 66 that flows properly into <br /> the next page or any additional pages associated with Rule 2 as necessary. <br /> 4. 1t is observed that the currently approved Map 23A is being incorporated in the proposed Map 23 as per the Colowyo <br /> Mine"change sheet".However,Map 23 is missing the cross-sections associated with the South Taylor Pit found on the <br /> Map 23A.These cross-sections are necessary as they refer the approved Map 20B—Pre-Mining and Post-Mining Cross <br /> Sections South Taylor. Please provide an updated Map 23 including the necessary cross-sections and associated <br /> references from Map 23A. <br /> If you have any questions,feel free to contact me. <br /> Sincerely, <br /> Zach Trujillo <br /> °F cO_<o <br /> 1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us I * * <br /> Jared S.
