Foidel Creek was electro shocked for presence or absence of aquatic life approximately <br />400 feet above the coal slurry deposition. This area of the creek consisted of pools with no surface flow observed. <br />Numerous Creek Chubs (Semotilus atromaculatus) were sampled upstream of the spill. <br />Approximately 1.5 to 2 miles below the coal slurry deposition Creek Chubs were also observed. Therefore, we can <br />assume there was a loss of aquatic life where the coal slurry was deposited. It would be extremely hard to quantify <br />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 will <br />reestablish once the proposed clean up is conducted. <br />Let me know if I can be of further assistance. <br />Sincerely, <br />X2~~7 GU~~ <br />Susan Wemer <br />Area Wildlife Manager <br />XC: Bill Atkinson <br />J.
