(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 March 14, 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 />The Division has corrected its internal network issues and has calculated an updated <br />Exhibit 13C — Cumulative Bond Schedule as well as the reclamation cost estimate (RCE) <br />liability increase associated with the changes proposed with TR -118. Attached are both <br />documents. It should be noted that the total amount associated with Exhibit 13C is <br />merely an updated to include all items proposed with the cumulative bond schedule and <br />not the RCE liability increase associated with the changes proposed with TR -118. The <br />majority of the tasks associated with the Cumulative Bond Schedule have been previously <br />approved through the Division's revisions process or accounted for in the approved <br />Colowyo Exhibit 13A — Reclamation Cost Estimate last updated with Midterm No. 7. The <br />total value of this proposed TR -118 liability increase is $820,776 56 (see attached cost <br />estimate). The Division's cost estimate is consistent with previous cost estimates <br />approved by both the Division and Colowyo. The Division respec fully requests a <br />response from Colowyo with any questions regarding this cost estimate or an acceptance <br />of the Division's estimate. <br />Response: Colowyo has included two versions of the summary sheets for the TR -118 <br />and Exhibit 13C RCE's for the Division. These sheets are not intended to become part of <br />the PAP, but rather a clear method to provide the Division with comments on the RCE's. <br />A column was added to the summary task sheets which provides Colowyo comments on <br />the TR -108 RCE and the Exhibit 13C RCE. <br />AN EQUAL OPPORTUNITY 1 AFFIR dATIVE ACTION EMPLOYER <br />A Touchstone Energy' Cooperative Kltl ► <br />CRAIG STATION ESCALANTE STATION NULLA STATION <br />P.O.
