No permit limitation exceedences occurred during this quarter. For Outfall 003 and 022, mare parameters were reported than required in the field statistics, because Routine Chronic Wet Testing was being performed at that time. Outfall 003 and 022 both fell short of meeting some of the frequency o(analysis' requirements for lab parameters. Outfall 003 stopped discharging on March 10 prior to a grab sample being obtained for lab parameters. That sample would have included the required quarterly TDS sample. On one of the samples for Outfall 022, Zinc-TR was not requested. The reported statistics demonstrate that these sites were visited per permit requirements, but the correct parameters were not tested. The tracking system, set up to catch these missed samples or lab parameters, is being modified to ensure all errors are detected prior to the end of the frequency period. All personnel involved will be retrained regarding the requirements imposed by this discharge permit. Chronic Whole Effluent Toxicity (WET) testing was performed at Outfalls 003 and 022 and indicated no toxicity to P. promelas or C. dubia. The "Concentration with Statistically Significant Difference in Lethality" was >100% for both species at each Outfall. Copies of the CDPS W ET Test Report Forms for both species are included in the submittal. Outfalls 004, 007, 009, 011, 012, 013, 014, 015, 016, 017, 018, 019, 020, 021, 023 and 024 along with Site 3001 did not discharge during this period. In order to reduce the amount of paper work, the following certification will be substituted for the actual DMR forms to cover the out(alls which did not discharge.
