No permit excursions were <br />noted for this period. Outfall 003A, flowed each week of June. Outfall 005A flowed only during the first two weeks of June. <br />Note that Ouffalls 002A, 006A, 007A, and D08A did not flow during the month of June, however DMR's for these Outfalls are <br />attached providing quarterly TDS data. <br />Quarterly Whole Effluent Toxicity (WET) tests were contlucted for Outfalls 005W and 007W in April 2003. Both tests indicated <br />that the effluent was not acutely toxic to Daphnia magna survival. <br />Outfalls 002A, 004A, OO6A, 007A, and 008A did not discharge; and therefore had no chemical tests during June. Outfall <br />020A/020W has not been constructed yet. Note that ponds A (Ouffall 001A and 001W), and H (Ouffall 009A) have been <br />deactivated following bond release, and have been removed from the newly amended permit, effective January 1, 2003. In <br />order to reduce the amount of paper work, the following certification will be substituted for the actual DMR forms to cover the <br />ouffalls, which did not discharge. <br />CERTIFICATION <br />1 certify under penalty of law that 1 have personally examined and am familiar with the inforration submitted herein; and <br />based on my inquiry of those individuals responsible for obtaining the information, I believe the submitted information is <br />true, accurate, and complete. 1 am aware that there are significant penalties for submitting false information, including the <br />possibility of fine and imprisonment.
