Crellln 3ooH <br />Sr. Envimnmen:al engineer <br />RE: Request for a Lease Modification for Federal Coal Lease D-034365 for Colowyo Coal Company <br />Dear Ms. Zurek: <br />In follow-up to our last conversation Colowyo Coal Company has revised the lease boundary in order to provide a more suitable <br />lease description. This revision is for the modification to Federal Coal Lease D-034365 under the terms and conditions of 43 CFR, <br />Chapter II, Subpart 3432 -Lease Modification. Colowyo Coal Company presently holds this lease and would like to expand the <br />lease to include an adjacent azea not presently under lease. <br />Granting this lease modification will allow up to 26'7,530 additional tons to be recovered with the existing operation. The proposed <br />lease modification adds 16.92 Acres in the existing Federal Coal Lease D-034365. Colowyo Coal Company owns the surface and <br />Bureau of Land Management administers the coal reserves in the proposed lease modification area. <br />The advantage of leasing these additional acres is to ensure maximum recovery of available tonnage with the existing operations in <br />that area. It is very unlikely that another company would be able to economically mine the same coal. Due to our close proximity <br />and access already established, Colowyo has the proper equipment and personnel to recover the tonnage in an efficient and effective <br />manner through tmckfshovel and highwall mining operations. <br />The two coal seams C and D are targeted for coal extraction in an adjacent ridge to the West Pit azea. (See Drawing No. 1) The <br />proposed lease modification also falls within the existing permit boundary as established with the State of Colorado <br />Please fmd enclosed a map illustrating the area of interest and the additional acreage requested. Across section of the coal seams <br />and the respective volumes has been provided, along with a description of how we calculated our tonnages and Colowyo's proposed <br />methods of mining. In addition we have submitted a new legal description to include the new lease azea. <br />Please discazd the previously submitted material dated August 18, 2004. If you have any questions regarding this information please <br />call me at your eazliest convenience. <br />Sinc~relL/%~~%L~'„'154// J <br />C~.
