(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). Tri-State received your adequacy letter dated August 7, 2018 and is providing <br />the response below to your adequacy concern on behalf of Colowyo. The Colowyo Mine <br />operates under Permit No. C-1981-019. <br />1. When reviewing Figure Exh. 7-15-1, the Division calculates a total of 286.1 acres of <br />immediate contributing area. However, the Structure Summary provided with the <br />SedCAD results shows a total of 285.1 immediate contributing area. Please review both <br />the proposed Figure 7-15-1 and associated SedCAD result demonstration to ensure all <br />acreage is accounted for. <br />Response: Some rounding discrepancies in acreages presented on Figure Exh. 7-15-1 and <br />the SEDCAD demonstration have been corrected, and both items have been resubmitted <br />accordingly. <br />2. As discussed between the Division and Colowyo, a reclamation cost estimate (RCE) to <br />reclaim the disturbances associated with TR -122 will be performed once the temporary <br />suspension on conducting RCEs has been lifted. <br />Response: Colowyo needs to construct these ditches in the fall of this year. Therefore, it <br />is becoming critical that this technical revision and the temporary suspension of RCE's <br />be resolved in a very timely manner. <br />AN EQUAL OPPORTUNIrY/AFFIRMATIVEACTION EMPLOYER <br />A Touchstone EneWCooperative <br />CRAIG STATION ESCAI ANTE STATION NUCLA STATION <br />P.O.
