PART <br />Page 14 of 47 <br />Permit No.: CO0000213 <br />2) Move to a TRE by identifying the necessary control program or activity and proceed with elimination of <br />the toxicity so as to meet the WET effluent limit. <br />If toxicity spontaneously disappears in the midst of a TIE, the permittee shall notify the Division within 10 calendar <br />days of such disappearance. The Division may require the permittee to conduct accelerated testing to demonstrate <br />that no pattern of toxicity exists, or may amend the permit to require an increased frequency of WET testing for <br />some period of time. If no pattern of toxicity is demonstrated through the accelerated testing or the increased <br />monitoring frequency, the toxicity incident response will be closed and normal WET testing shall resume. <br />The control program developed during a TRE consists of the measures determined to be the most feasible to <br />eliminate WET. This may happen through the identification of the toxicant(s) and then a control program aimed <br />specifically at that toxicant(s) or through the identification of more general toxicant treatability processes. A control <br />program is to be developed and submitted to the Division within 180 calendar days of beginning a TRE. Status <br />reports on the TRE are to be provided to the Division at the 60 and 120 calendar day points of the TRE investigation. <br />If toxicity spontaneously disappears in the midst of a TRE, the permittee shall notify the Division within 10 calendar <br />days of such disappearance. The Division may require the permittee to conduct accelerated testing to demonstrate <br />that no pattern of toxicity exists, or may amend the permit to require an increased frequency for some period of <br />time. If no pattern of toxicity is demonstrated through the accelerated testing or the increased monitoring <br />frequency, the toxicity incident response will be closed and normal WET testing shall resume. <br />d. Toxicity Reopener <br />This permit may be reopened and modified to include additional or modified numerical permit limitations, new or <br />modified compliance response requirements, changes in the WET testing protocol, the addition of both acute and <br />chronic WET requirements, or any other conditions related to the control of toxicants. <br />E.
