Sherman <br />Executive Director <br />Ronald W. Cattany <br />Division Director <br />Natural Resource Trustee <br />Twentymile Coal Company (TCC) submitted NPDES Discharge Monitoring Reports (DMRs) for second <br />quarter 2009 and June 2009, Colorado Department of Public Health and Environment CDPS permit no. <br />CO-0027154 on July 31, 2009. <br />TCC reports that in June outfalls 003A (Pond B), 005A/MON5/005W (Pond D), 006A (Pond E), and 008A <br />(Pond G) all discharged. No parameters exceeded the standards for any of these outfalls in June. <br />No parameter exceedances were reported for the quarterly parameters, although pH for outfall 006A (Pond <br />E) was approaching the maximum. The second report for outfall 007A (Pond F) contains results for some <br />of the parameters but is missing results for pH and TSS. Please provide an explanation as to why these <br />parameters are missing, and provide these results. Although outfall 007A did not discharge in June, it did <br />discharge during the quarter; therefore analysis should have been completed. <br />In TLC's May DMR for CO-0027154, the form for Outfall 005A was not included with the report. TCC's <br />cover letter indicated that corrections were being made to the form and that the DMR for Outfall 005A <br />would be forthcoming. The Division still has not received the DMR form for outfall 005A for May 2009. <br />Please submit a copy of this report to the Division. <br />The reports are in compliance with Rule 4.15.13(2)(iii). Thank you for prompt submittal of these reports. <br />Sincerely, <br />4*Jan H.
