COLORADO <br /> Division of Reclamation, <br /> Mining and Safety <br /> Department of Natural Resourccs <br /> February 10,2020 <br /> Tony Tennyson <br /> Colowyo Coal Company L.P. <br /> 5731 State Highway 13 <br /> Meeker, CO 81641 <br /> Re: Colowyo Coal Mine (Permit No. C-1981-019) <br /> Technical Revision No. 136(TR-136) <br /> Adequacy Review <br /> Dear Mr.Tennyson: <br /> After reviewing TR-136 from Colowyo Coal Company L.P.(Colowyo),the Division has the following <br /> comments: <br /> 1. Both TR-135 and TR-136 are proposing to change and update Volume 1,Rule 4,Pages 441 through <br /> 4-59. The Division's plan is to approve TR-135 prior to TR-136. To ensure all updates are included <br /> into the Colowyo PAP,please update the proposed Volume 1,Rule 4,Pages 4-41 through 4-59 under <br /> TR-136 to include the changes with TR-135. <br /> 2. In proposed Volume 2C,Appendix Exh7-14D,it states the Section 16 Fill Ditch is a length of 860 feet. <br /> However,as shown on approved maps as well as the currently approved Volume 2C,Appendix Exh7- <br /> 14D,the Section 16 Fill Ditch has the total length 683 feet. Please provide the Division clarification <br /> on the length difference with what is being proposed in TR-136 for the Section 16 Fill Ditch. <br /> 3. As requested with the proposed TR-136, all currently approved items within Colowyo's PAP's <br /> Volume 2E, Exhibit 7-PP will be updated and replaced. Given the complexities with structure <br /> networking and contributing watersheds to the Prospect Pond, the Division's feels that it may be <br /> necessary to maintain appropriate figures that are being requested for removal such as Figures Exh.7- <br /> 14PP-8 and Figures Exh. 7-14PP-9. Please provide updated figures that show the structures and <br /> watershed details similarly to the above mentioned figures. <br /> If you have any questions,feel free to contact me. <br /> Sincerely, <br /> 1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us * *' <br /> Jared S.
