Dan — I updated AVS with the latest ownership and control information for Western Fuels- Colorado, LLC and Tri -State
Generation and Transmission Association, and then ran your requested AVS check. There are no violations reported for
Western Fuels- Colorado or its parent corporation, Tri -State Generation and Transmission Association. When the
acquisitions of Colowyo Coal Company, Kennecott Colorado Coal Company, and Taylor Creek Holding Company are
complete I will need to update AVS again; so please let me know when the sale is complete. A copy of the AVS report is
attached.
