PARTI <br />Page No. 7 ' <br />Permit No.: CO-0000132 <br />e. Request For Relief <br />The pemrittee may request relief from further investigation and testing where the toxicant has not been determined and <br />the Division has determined suitable treatment does not appear possible. In requesting such relief, the permittee shall <br />submit material sufficient to establish the following: <br />i. It has complied with terms and conditions of the pemut compliance schedule for the PTUTIE investigation and other <br />appropriate conditions as may have been required by the Division; <br />ii. During the period of the toxicity incident it has been incompliance with all other permit conditions, including, in the <br />case of a POTW, pretreatment 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. Despite the circumstances described in pazagraphs i, and iii. above, the source and/or cause of toxicity could not be <br />located or resolved. <br />If deemed appropriate by the Division, the permit or the compliapce schedule maybe modified to revise the ongoing <br />monitoring and toxicity investigation requirements to avoid an unproductive expenditure of the permittee's resources, <br />provided that the underlying obligation to eliminate any continuing exceedance of the toxicity limit shall remain. <br />L Spontaneous Disappearance <br />If toxicity spontaneously disappeazs at any time after a test failure, the permittee shall notify the Division in writing <br />within 14 days of a demonstration of disappearance of the toxicity. The Division may iequire the pemuttee to develop <br />and submit additional information which may include, but is not limited to, the results of additional testing. If no pattern <br />of toxicity is identified or recurring toxicity is not identified, the toxicity incident response is considered closed and <br />normal WET testing shall resume. <br />g. Toxicity Reopener <br />This permit maybe reopened and modified (following proper administrative procedures) to include new compliance <br />dates, additional or modified numerical permit limitafions, a new or different compliance schedule, a change in the whole <br />effluent toxicity testing protocol, or any other conditions related to the control of toxicants if one or more of the following <br />events occur: <br />i. Toxicity has been demonstrated in the effluent and the permit does not contain a toxicity limitation. <br />ii. The PTUTIE results indicate that the toxicant(s) represent pollutant(s) that may be controlled with specific numerical <br />limits, and the Division agrees that the numerical controls aze the most appropriate course of action. <br />iii. The PTI/TIE reveals other unique conditions or characteristics which, in the opinion of the Division, justify the <br />incorporation of unanticipated special conditions in the permit. <br />B. MONITORING REQTIII2EMENTS <br />1. Freouencv and Samnle Tvpe <br />In order to obtain an indication of the probable compliance or noncompliance with the effluent limitations specified in Part <br />LA.1, the pemuttee shall monitor all effluent pazameters at the following frequencies. Such monitoring will begin <br />immediately and last for the life of the permit unless otherwise noted. The results of such monitoring shall be reported on the <br />Discharge Monitoring Report form (See Part I.E.) <br />
