Ponds A (Outfall 001), D (Outfall 005), and E (Outfall 006) discharged during this period. However, <br />freezing conditions prevented measurement of flows discharging from the Pond A flume, which only discharged the first week <br />of this period. No permit limitation exceedences occurred during this quarter. <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 />Outtalls 001, 005 and 007 are being tested for Hardness in addition to the required parameters, however, as noted below, 007 <br />did not discharge and was omitted for this period. A copy of those results is included in this submittal. <br />Outfalls 002, 003, 004, 007, 008 and 009 did not discharge; and therefore have no chemical or toxicological tests during this <br />period. Outfall 020 has not been constructed yet; therefore there is no discharge to enable chemical or toxicological testing to <br />date. Outialls 010, 016 and 017 have been eliminated from this permit. 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 />CERTIFICATION <br />I certify under penalty of law that I have personally examined and am /amiliar with the in/ormation submitted herein; ano <br />based on my inquiry o/ those individuals responsible for obtaining the in(onnation, I believe the submitted in/ormation is <br />true, accurate, and complete. I am aware that there are significant penalties for submitting false in/ormation, including the <br />possibility o/ /ine and imprisonment. See 18 U.S.C. § 1001 and 33 U.S.C. § 1319.
