PARTI <br />Page No. 6 <br />Permit No.: CO-0038342 ' "" - f <br />i. Proceed to conduct the PTI/I'IE investigation as descrbed in subpar[ d, or <br />ii. Conduct accelerated testing using the single species found to be more sensitive. <br /> <br />If accelerated testing is being performed, the permittee shall provide written notification of the results within 14 <br />calendar days of completion of the Pattern of Tordcity/No Toxicity demonstration. Testing will be at least once <br />every two weeks for up to five tests until; 1) two consecutive tests fail or three of five tests fail, in which case a pattern of <br />toxicity has been demonstrated or 2) two consecutive tests pass or three of five tests pass, in which case no pattern of <br />toxicity has been found. If no pattern of toxicity is found the toxicity episode is considered to be ended and routine <br />testing is to resume. If a pattern of toxicity is found, a PTI/TIE investigation is to be performed. If a pattern of toxicity is <br />not demonstrated but a significant level of erratic toxicity is found, the Division may require an increased frequency of <br />routine monitoring or some other modified approach. <br />d. PTI/TIE <br />PTIITIE investigation. The Division may extend the time frame for investrgation where reasonable justification exists. <br />A request for an extension rrwst be made in writing and received prior to the ] 20 day deadline. Such request must <br />include a justification and supporting data for such an extension. <br />The permittee may use the time for investigation to conduct a PTI or move directly into the TIE. A PTT consists of a <br />brief seazch for possible sources of WET, which might reveal causes of such toxicity and appropriate coaective actions <br />more simply and cost effectively than a fomral TIE. If the PTI allows resolution of the WET incident, the TIE need not <br />necessarily be conducted. If, however, WET is not identified or resolved during the PTI, the TIE must be conducted <br />within the allowed 120 day time frame. <br />• Any permittee that is required to conduct a PTIIIIE investigation shall do so in conformance with procedures identified <br />in the following documents, or as subsequently updated: 1) Toxicity Identification Evaluation: Characterization of <br />Chronically Toxic Effluents. Phase I, EPA/600/6-91/OOSF May 92, 2) Methods for Acuaric Toxicity Identification <br />Evaluations.

As indicated by the title, this procedure is intended to confum <br />that the suspecfed toxicant is holy the roxicaat. This investigation is optional. <br />Within 90 days of the determination of the toxicant or no later than 210 days after demonstration of toxicity, whichever is <br />sooner, a control program is to be developed and received by the Division. The program shall set down a method and <br />procedure for elimination of the toxicity to acceptable levels. <br />e. Request For Relief <br />The perrnittee may request relief from further investigation and testing where the toxicant has not been determined and <br />suitable treatment does not appeaz possible. In requesting such relief, the pemuttee shall submit material sufficient to <br />establish the following: <br />i. It has complied with temrs and conditions of the permit compliance schedule for the PTL'TIE investigation and other <br />appropriate conditions as may have been required by the W QCD; <br />ii, During the period of the toxicity incident it has been in compliance with all other permit conditions, including, in the <br />case of a POTW, prefreatment requirements; <br />iii. During the period of the toxicity incident it has properly maintained and operated all facilities and systems of <br />• treatment and control; and <br />iv.
