WILLIAMS FORK MINES <br />29515 Routt County Road # 27 <br />Oak Creek, Colorado 80467 <br />(970) 879-3800 <br />October 26, 2015 <br />Ms. Christy Pickens <br />Colorado Department of Public Health and Environment <br />Water Quality Control Division - Permits and Enforcement <br />4300 Cherry Creek Drive South <br />Denver, CO 80222-1530 <br />RE: PERMIT CO -0034142; WILLIAMS FORK MINES THIRD QUARTER 2015 DMR SUBMITTAL <br />Dear Ms. Pickens: <br />Outfall 022A ( site 1 SP) flowed the first two weeks of the period. Outfalls 003AI003X (site 5D), and 024A1024X (site 9P3) did <br />not discharge during this period. One exceedance was noted for 022A, for the 30 day average of total recoverable iron, at <br />1110 ug/L versus the permit limit of 1000 ug/L. This maybe the result of decreasing flows and less dilution as the spoil spring <br />dried up. The site has subsequently dried up and has not discharged as of the date of this cover letter. Historically the site <br />may not discharge until next spring, unless there is a significant precipitation event. <br />Please contact me directly at (970) 870-2750 with any questions.. <br />' r <br />Brian A.
