During this quarter, three NPDES outfalls were active. Outfalls 001 and 002 <br />discharged routinely throughout the quarter. Outfall 011 discharged in response to fall precipitation events in <br />October and November. Outfalls 005, 008, 009, 012, 013, 014, 015, 016, 017 018, 019, 020, 021, 022, 023 <br />and 024 did not discharge during the quarter. Values reported on the enclosed DMRs represent the maximum <br />(or minimum as applicable) monthly/daily 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. One outfall was sampled for WET analyses during the quarter. Two species acute tests were <br />completed at outfall 011. No exceedances of WET test limitations were observed at any tested outfalls. <br />The enclosed NOAA weather summary reports show the temperatures and precipitation measurements for the <br />period mentioned. Daily precipitation measurements are recorded at 7:00 a.m. as well as daily maximum and <br />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 />Thank you for your cooperation in this matter.
