COAL <br />COMPANY <br />steady. Water from the spring that flows into East Taylor Pond was sarnpled on June 21, 2012 <br />and laboratory analysis was received on June 26, 2012. The sample was taken at a location just <br />upstream from its inflow into the pond. The laboratory analysis for the spring indicated the <br />level for Total Suspended Solids were 6 mg /L, compared to 46 mg /L for the Outf all analysis <br />taken the same day. East Taylor Pond was dredged during August of 2011, and 2088 yards of <br />material was removed from East Taylor Pond. Please see attached climatological data, sample <br />analysis reports, and pictures taken of East Taylor Pond during the month of June. <br />Colowyo's historical laboratory analysis data does not show a trend toward any type of elevated <br />levels at this outfall. The elevated levels Colowyo does experience are associated with either a <br />precipitation or runoff event. Colowyo does not believe that the elevated levels are related in <br />any way to a lack of proper pond function as routine inspections of the pond show that it is <br />functioning as designed. Colowyo will continue to closely monitor this and all other outfalls for <br />indications of proper impoundment function. <br />If you should have any additional questions or concerns please feel free to contact me at you <br />convenience at (970) 824 -1573. <br />Sincerely, <br />,„„,,,, A <br />Chip Brown <br />Environmental Engineer <br />CC: CDRMS /Rob Zuber <br />NPDES Reports Binder w /encl. <br />C.F. 21.1.2 <br />
