TRAPPER MININD INC. <br />April 22, 2009 <br />CERTIFIED <br />EC91M' <br />M0 2 tooo <br />Ms. Carla Lenkey Divisio Qf Rociamation, <br />Colorado Department of Public Health and Environment Mining and Safety <br />WQCD-PE-132 <br />4300 Cherry Creek Dr. South <br />Denver, CO 80222-1530 <br />Subject: First Quarter 2009 Colorado Wastewater Discharge Monitoring Reports <br />Permit No. CO-0032115 <br />Dear Ms. Lenkey: <br />Enclosed are Trapper Mine's First Quarter 2009 Colorado Wastewater Discharge Monitoring Reports for the <br />period 01/1/09-03/31/09. During this quarter, five NPDES outfalls were active. Outfalls 001, 002 and 020 <br />discharged routinely throughout the quarter. Outfalls 011 discharged in response to spring snowmelt occurring in <br />February through March. Outfall 021 discharged in response to spring snowmelt in mid March. Outfalls 005, <br />008, 009, 012, 013, 014, 015, 016, 017, 018, 019, 022, 023 and 024 did not discharge during the quarter. <br />Values reported on the enclosed DMRs represent the maximum (or minimum as applicable) monthly/daily <br />values generated at each outfall during the quarter. <br />Also enclosed are monthly NOAA weather summaries for the reporting period and WET test report forms as <br />applicable. Three outfalls were sampled for WET analyses during the quarter. Two species acute tests were <br />completed at outfalls 011, 020 and 021. No exceedances of WET test limitations were observed at any tested <br />outfalls. <br />This winter resulted in average snow pack for the site during most of the reporting period. Snow melt was fairly <br />slow throughout the period. Melting periods during late February and heavy snows in March resulted in some <br />increased flows during the period. The enclosed NOAA weather summary reports show the temperatures and <br />snow depth measurements for the period mentioned. Daily precipitation measurements are recorded at 7:00 <br />a.m. as well as daily maximum and minimum temperatures from the previous 24 hours. <br />No exceedences of primary effluent limitations occurred at any outfall during the quarter. Trapper is required to <br />maintain sediment levels in ponds at or below 60% of the pond volume. All outfalls have been properly <br />maintained and no ponds exceeded the 60% threshold for sediment accumulation. <br />If you have any further questions or comments concerning the enclosed information, feel free to contact me. <br />Sincerely, <br />GCR [WATER\DMR Cover Letter\1° Quarter 20071 <br />Enclosure <br />c Jason Musick, CDRMS <br />File 109.2.7 <br /> <br />Graham Roberts <br />EHS Specialist <br />P.O.
