PART I <br />Page 15 of 48 <br />Permit No.: CO0038342 <br />collected may be presented to the WQCC for consideration at the next appropriate triennial review of <br />the stream standards; <br />2) Move to a TRE by identifying the necessary control program or activity and proceed with elimination <br />of 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 <br />calendar days of such disappearance. The Division may require the permittee to conduct accelerated <br />testing to demonstrate that no pattern of toxicity exists, or may amend the permit to require an <br />increased frequency of WET testing for some period of time. If no pattern of toxicity is demonstrated <br />through the accelerated testing or the increased monitoring frequency, the toxicity incident response <br />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 <br />to eliminate WET. This may happen through the identification of the toxicant(s) and then a control <br />program aimed specifically at that toxicant(s) or through the identification of more general toxicant <br />treatability processes. A control program is to be developed and submitted to the Division within 180 <br />calendar days of beginning a TRE. Status reports on the TRE are to be provided to the Division at the 60 <br />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 <br />10 calendar days of such disappearance. The Division may require the permittee to conduct accelerated <br />testing to demonstrate that no pattern of toxicity exists, or may amend the permit to require an <br />increased frequency for some period of time. If no pattern of toxicity is demonstrated through the <br />accelerated testing or the increased monitoring frequency, the toxicity incident response will be closed <br />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, <br />new or modified compliance response requirements, changes in the WET testing protocol, the addition of <br />both acute and chronic WET requirements, or any other conditions related to the control of toxicants. <br />E. COMPLIANCE SCHEDULES <br />1. Activities to Meet Final Limits (Outfalls 002) - In order to meet the 30 -day average and daily -max limitations at <br />outfall 002 for metals parameters potentially dissolved cadmium, total recoverable iron, potentially dissolved <br />lead, total mercury, and potentially dissolved selenium, the following schedule is included in the permit. <br />Code Event Description Due Date <br />43699 <br />Facility <br />Submit a report that identifies sources of metals to the <br />1/01/2016 <br />Evaluation Plan <br />facility and identifies strategies to control these sources <br />or treatment alternatives such that compliance with the <br />final limitations may be attained. <br />00899 <br />Implementation <br />Submit a progress report summarizing the progress in <br />Schedule <br />implementing the strategies to control sources such that <br />1/01/2017 <br />compliance with the final metals and EC/SAR limitations <br />may be attained. <br />CS017 <br />Achieve Final <br />Submit study results that show compliance has been <br />5/31/2018 <br />Compliance <br />attained with the final metals and EC/SAR limitations. <br />2. Activities to Meet Final Limits (Outfalls 001 and 004) - In order to meet the 30 -day average and daily -max <br />limitations at outfalls 001 and 004 for total recoverable iron the following schedule is included in the permit. <br />
