(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 />technical revision 123 (TR -123) to Permit No. C-1981-019. <br />TR -123 proposes using the Collom Aspen reference area instead of the Danforth Hills <br />reference area to evaluate revegetation success for the South Taylor reclamation units. The <br />Danforth Hills aspen reference (1984) cannot be controlled by Colowyo or managed in <br />accordance with post mine land use because the reference area is located on BLM property <br />(Rules 4.15.7(3)(ii) and 4.15.7(3)(d)). Therefore, contained within TR -123 application is a <br />statistical demonstration that the Collom Aspen reference area (2005) is a suitable replace for the <br />Danforth Hills reference area, and Colowyo can meet the requirements of Rules 4.15.7(3)(ii) and <br />4.15.7(3)(d) with the Collom Aspen reference area. <br />Also included with this technical revision are a revision application, a change of index <br />sheet to ease incorporation into the permit document, and a public notice for your review. If you <br />should have any additional questions or concerns please feel free to contact Tony Tennyson at <br />(970) 824-1232 or ttennysonQristategt.org. <br />Sincerely, <br />2 1 4 " J-/, C <br />Daniel J.
