The coal lease provided in the NOI is between <br />the State (of Colorado) Board of Land Commissioners and Cyprus Western Coal Company. Please provide a copy of <br />the document assigning this lease from Cypnes Western Coal Company to Twentymile Conl Compntty. This <br />assignment may be on file with the State Board of Land Commissioners. <br />Response: Please refer to pages 2.03-12 and 2.03-25 of the approved Twentymile PAP (copies attached) for transfer <br />documentation from Cyprus Western Coal Company to RAG American Coal Company. Please refer to approved <br />revision TR04-43 for documentation pertaining to the transfer from RAG to Peabody Energy and the link to <br />Twentymile Coal Company. Both of the referenced transfers included the transfer of all assets and assignments of <br />related ownership agreements and leases, and were previously reviewed and approved by the Division. <br />5) It is stated on page 4 of the NOI application, under the section "Site Development -Exploration Access ", that <br />"unimproved ranch roads and jeep trails will be utilized to access exploration drill-sites adjacent to existing roads in <br />order to minimize any new disturbance associated with the proposed exploration activities ". However, on page 6 of <br />the NOI application, under the section "Exploration Site Reclamation ", it is stated in paragraph 2) that "any excess <br />drill cuttings will be spread over the drill pad, and drill pads, trenched areas, and any new access road segments <br />graded to approximate their original configuration,n and blend with the adjacent terrain ". If in fact only existing <br />ranch road and jeep trails will be used for this project, please remove the reference in this paragraph to "new access <br />road segments ". <br />Response: References to, "new access road segments" have been removed from the NOI Application. A copy of the <br />revised application accompanies these responses.. <br />6) It is stated on page 4 of the NOI application, under the section "Site Development-Drill-Pad Construction", that <br />"Pad construction will begin with removal of existing topsoil material for use in reclaiming the pad ". In accordance <br />with the requirements of Regulation 4.27.4(5), please modify this paragraph to include the following statement: <br />"Prior to earth-moving or excavations of any type, the A and B horizons will be salvaged and stored in an <br />area that will be undisturbed and not subject to excessive wind or water erosion. The underlying subsoil <br />materials will, if necessary, be salvaged and stored in an area separate from the A and B horizons. " <br />Response: Since no road disturbance is planned, the existing statement addresses the intent of the referenced Rule, <br />with the exception of provision for secure storage to avoid erosion and loss of the topsoil resource. The referenced <br />text has been revised to incorporate this provision, with copies of the revised page accompanying these responses. <br />TCC has worked closely with the Division's representative on our prior exploration work to minimize overall <br />disturbance and maximize reclamation success. In practice, this has translated into recovery, stockpiling, and <br />replacement of soil in the primary rooting zone for the dominant site vegetation, and has resulted in faster and more <br />effective reestablishment of native vegetation than a more aggressive soil-recovery program. <br />
