Outfalls 003, 022 and 024 discharged during this reporting period, however, Outfalls 003 and 024 did not commence <br />discharge until September. No permit limitation exceedences occurred during this quarter. <br />Chronic Whole Effluent Toxicity (WET) testing was performed at Outfalls 003, 022 and 024, indicating no toxicity to P. <br />Promelas or C. Dubia. The "Concentration with Statistically Significant Difference in Lethality" was >700% for both species at <br />each Outfall. Copies of the CDPS W ET Test Report Forms for both species are included in the submittal. <br />The WET tests conducted this quarter required extra visits to these sites, thus producing additional field parameter values <br />which were calculated into the statistics reported on the DMRs. <br />Outfalls 004, 007, 009, 011, 012, 013, 014, 015, 016, 017, 018, 019, 020, 021 and 023 along with Site 3001 did not discharge, <br />and therefore have no chemical or toxicological tests during this period. In order to reduce the amount of paper work, the <br />following certification will be substituted for the actual DMR forms to cover the outfalls which did not discharge. <br />I certiry under penalty o/law that I have personally examined and am familiar with the information submitted herein; ana <br />based on my inquiry o/ those individuals responsible for obtaining the in/ormation, 1 believe the submitted in/ormation is <br />true, accurate, and complete.
