Special R~rts: Special reports are required in the event of a spi17 bypass, or other noncompliance. Please refer to <br />Part I.E. of the permit for reposting requirements. <br />D. Addlriona! Terms and Conditions <br />1. S~atorv and Certification Requirements: Signatory and certification requirements for reports and subminals are <br />discussed in Part LE.6. of the permit. <br />2. Comoliance Schedules: All information and written reports required by the following compliance schedules should be <br />directed to the Permits Unir for, final review unless otherwise stated. <br />a. Twelve Time Analvsis: To ensure that the water quality standards for total recoverable arsenic, dissolved cadmium, <br />dissolved copper, total recoverable trivalent chromium, dissolved iron, total recoverable iron, dissolved manganese, <br />total mercury, dissolved nickel, dissolved selenium, dissolved silver, and dissolved zinc are being protected, the <br />perminee shall conduct special samplingfor the appropriate metals at ou all 015 as specified in the following <br />paragraph and in Part LB.3. ojthe permit beginning June I, 2004 (or upon commencement ofdischarge, whichever <br />occurs first), and following once per month thereafter. <br />Twelve consecutive monthly grab samples far total recoverable (TR) arsenic, potentially dissolved (PD) cadmium, <br />TR trivalent chromium, PD copper, dissolved and TR iron, PD manganese, total mercury, PD nickel, PD selenium, <br />PD silver, and PD zinc shall be collected at outfall 01 S and analyzed with all results being submitted at the end of <br />the sampling period. A summary report in the form of a letter shall be submitted to the Permits Unit by September <br />30, 2005. This report shall include all individual sample results collected over the twelve month period. Ifsampling <br />is incomplete, this shall be noted in the report. Ifsampling has not yet been completed by this date, this twelve time <br />analysis requirement shall continue until twelve samples have been collected and analyzed and the results submitted <br />to the Permits Unit. <br />If the monitoring shows that there is a reasonable potential for any of these parameters to cause exceedence of the <br />applicable water quality standards, thepermit may be reopened to add limits and/or monitoring subject to public <br />notice requirements. <br />Cade Event Permit Citation Due Date <br />50008 Submit a summary report of all twelve monthly results with Parts LA.4. and /.B.3. 9/30/05 <br />cover letter to the Permits Unit. <br />b. Materials Containment Plan: Previously, the permittee submitted an engineered spill plan. An update to the plan is <br />required to be filed within 90 days of the permit effective date, detailing all changes that have occurred since the <br />original submittal. If no changes have occurred, a lever to this effect is required. For specific requirements, refer <br />to Panl.D.l. ofthepermit. <br />E. Waste Minimization/PoUution Prevention <br />Waste minimization and pollution prevention are two terms that are becoming increasi»g!y more common in industry today. <br />Waste minimization includes reducing the amount ojwaste at the source through changes in industrial processes, and reuse <br />and recycling of wastes for the original or some otherpurpose (such as materials recovery or energy production). Pollution <br />prevention goes hand-in-hand with waste minimization. If the waste is eliminated at Ihefront of the line, it will not have to <br />be treated at the end of the line. The direct benefits to the industry are often significant, both in terms of increased profit and <br />in public relations. This program can affect all areas of process and waste control with which an tndustry deals. <br />Elimination or reduction of a wastewater pollutant can also result in a reduction in an air pollutant or a reduction in the <br />amount ofhazardous materials that must be handled or disposed. <br />This discharge permit does not spec~cally dictate waste minimization conditions ai this time. The Division does strongly <br />encourage the permittee to continue working to developing and implementing a waste minimization plan. Several industries <br />have already developed plans and found that implementation resulted insubstantial savings. Both the Colorado Department <br />of Public Health and Environment and the Environmental Protection Agency (EPA) have information and resources <br />available. For more in-depth information, please contact these agencies. <br />Jon Kublc <br />Gast Revised: 3/19/2004 <br />
