(COLOWYO); CDPS NO. CO-00045161 <br />THIRD QUARTER 2004 DISCHARGE MONITORING REPORTS (DMR) <br />Deaz Ms. Lenkey, <br />Colowyo is submitting the third quarter discharge monitoring reports to the Water Quality Control Division for calendar <br />year 2004. Please find the DMR reports attached for your review. <br />Measurable discharge for the third quarter occurred at outfalls 001 A and 007A. Outfall 001 A discharged continuously <br />throughout the third quarter. <br />Field measurements of outflow were taken four times in July, four times in August and five times in September at <br />outfall OOIA. Outfall 007A dischazged for approximately seven days in July. Field measurements of outflow were <br />taken twice during this period of time. Laboratory samples were taken at outfall 001 A in July (1 sample), August (1 <br />sample) and September (1 sample). A single laboratory sample was taken at outfall 007A in July while the pond was <br />discharging. <br />The laboratory sample taken at Outfall 007A on July 22 exceeded the allowances for Total Suspended Solids (114 <br />mg/L) and Settleable Solids (3 mg/L/h). Results from the laboratory sample taken at Outfall 001 A on August 10, <br />exceeded the allowance for Total Suspended Solids (230 mg/L). Please see the attached CDPS Exceedance Reports for <br />more detailed information about these exceedences. Water monitoring forms for these samples are also attached. We <br />believe that sampling ercors were responsible for these exceedences. <br />Thank you for your consideration. Please feel free to contact me if you have any questions or concerns. I can be <br />reached at (970)824-1532. <br />Sincerely, i^~/~ ~---- <br />C.
