Outfall 022A flowed each week of the quarter. No permit excursions were noted during this period. <br />In 2004, BTU Empire received approval from CDPHE to reduce the frequency of Whole Effluent Toxicity (WET) testing for <br />Outfalls 003X, 022X, and 024X to an annual basis (a change from the previous quarterly basis). Thus, chronic WET testing <br />was last performed at Outfalls 003X and 022X during the second quarter of 2004. At that time W ET tests for 003X and 022X <br />indicated no toxicity to either P. promelas (fathead minnow) or C. dubia. Ouffall 024X did not flow in 2004 this year. WET <br />testing is anticipated to occur during the second quarter of 2005. <br />Outfalls 003A, 004A, 007A, 009A, 011A, 012A, 013A, 014A, 015A, 016A, 017A, 018A, 019A, 020A, 021 A, 023A, and <br />024A/024X, along with Site 3001, did not discharge 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 certify under penalty of law that I have personally examined and am familiar with the information submitted herein; and <br />based on my inquiry of those individuals responsible for obtaining the information, 1 believe the submitted information is <br />true, accurate, and complete. I am aware that there are srgnifrcant penalties lorsubmttting false informatton, including the <br />possibility o/ /ine and imprisonment. See 18 U.S.C. § 1001 and 33 U.S.C. § 1319.
