Walker <br />Division of Reclamation, Mining and Safety <br />1313 Sherman Street, Room 215 <br />Denver, Colorado 80203 <br />Re: Twentymile Coal Company Minor Revision <br />Dear Mr. Walker: <br />On September 13, 2006 Aquatic Biologist Bill Atkinson conducted a site inspection of Foidel Creek in relation to <br />the coal slurry deposition. Foidel Creek was electro shocked for presence or absence of aquatic life <br />approximately 400 feet above the coal slurry deposition. This area of the creek consisted of pools with no surface <br />flow observed. Numerous Creek Chubs (Semotilus atromaculatus) were sampled upstream of the spill. <br />Approximately I.5 to 2 miles below the coal slurry deposition Creek Chubs were also observed. Therefore, we <br />can assume there was a loss of aquatic life where the coal slurry was deposited. It would be extremely hard to <br />quantify the amount of loss within the deposition area. <br />My staff and the Aquatic Biologist have review the proposed clean up plan and believe that aquatic organisms <br />will reestablish once the proposed clean up is conducted. <br />Let me know if I can be of further assistance. <br />Sincerely, <br />Susan Wemer <br />Area Wildlife Manager <br />XC: Bill Atkinson <br />J.
