(Tri-State), is the parent <br />company to Axial Basin Coal Company, which is the general partner to Colowyo Coal Company <br />L.P. (Colowyo). Therefore, Tri-State on behalf of Colowyo is submitting three (3) copies of <br />minor revision 169 (MR -169) to Permit No. C-1981-019. <br />MR -169 proposes four geotechnical drill holes adjacent to Wilson Reservoir and State <br />Highway 13. These borings are necessary to obtain data for future boring under State Highway <br />13 to install a raw water pipeline to support the Collom mining operation, and to obtain data to <br />construct a new pump house at Wilson Reservoir. Colowyo will be incorporating the required <br />information related to this drilling program in Section 12 of the 2017 Annual Reclamation <br />Report in accordance with Colowyo's permit to mine commitments. <br />With this additional geotechnical drilling it is requested that the Division provide a <br />revised reclamation cost estimate to include this drilling in the reclamation activities to occur <br />onsite. <br />Also included with this minor revision are a revision application and a change of index <br />sheet to ease incorporation into the permit document. If you should have any additional <br />questions or concerns please feel free to contact Tony Tennyson at (970) 824-1232 or <br />tte11nyson@1dstategt.org. <br />Sincerely, <br />Daniel J.
