COLORADO DEPARTMENT OFI IC HEALTH AND ENVIRONMENT Water lily Control Division Rationale - Page 7, CO- 0027529 C. Reporting Table VI-3 - Effluent Monitoring Requirements - cont 'd Effluent Parameter Monitoring Frequency Sample Type For Point 004A Flow, MGD Weekly Instantaneous pll, su Weekly In -Situ Oil and Grease, mg /l Weekly Visual TSS, mg /1 Weekly Grab Cadmium, Total, mg /1 Weekly Grab Copper, Total, mg /l Weekly Grab Lead, Total, mg /I Weekly Grab Zinc, Total, mg /I Weekly Grab TDS, mg/1 Quarterly Grab For every outfall with oil and grease monitoring, in the event an oil sheen or floating oil is observed, a grab sample shall be collected, analyzed, and reported on the appropriate DMR. In addition, corrective action shall be taken immediately to mitigate the discharge of oil and grease. A description of the corrective action taken should be included with the DMR. 1. Discharge Monitoring Report: Sunnyside Gold Corporation must submit a Discharge Monitoring Report (DMR) on a monthly basis to the Division. This report should contain the required summarization of the test results for parameters shown in Table W -3 and Part I.B.1 of the permit. See the permit, for details on such submission. 2. Special Reports - Special reports are required in the event of a spill, bypass, or other noncompliance. Please refer to Part I, Section D. 4. of the permit for reporting requirements. D. Additional Terms and Conditions 1. Signatory Requirements - Signatory requirements for reports and submittals are discussed in Part I, Section D.1. of the permit. 2. Materials Containment Plan: On February, 1988, the permittee submitted an engineered spill plan. An update to the plan is required to be filed within 90 days of the permit effective date, detailing all changes which have occurred since the original submittal. Ifno changes have occurred, a letter to this effect is required. For specific requirements, refer to Part I.E. of the permit. E. Waste Minimization/Pollution Prevention Waste minimization and pollution prevention are two terms that are becoming increasingly more common in industry today. Waste minimization includes reducing the amount ofwaste at the source through changes in industrial processes, and reuse and recycling of wastes for the original or some other purpose such as materials recovery or energy production. Pollution prevention goes hand -in -hand with waste minimization. If the waste is eliminated at the front of the line, it will not have to be treated at the end of the line. The direct benefits to the industry are often significant - both in terms of increased profit and in public relations. This program can affect all areas ofprocess and waste control with which your industry deals. Elimination or reduction of a wastewater pollutant can also result in a reduction of an air pollutant or a reduction in the amount of hazardous materials that you have to handle and/or dispose of This discharge permit does not specifically dictate waste minimization conditions at this time. We strongly encourage the permittee to develop a waste minimization plan. Several industries have already developed plans and found that implementation resulted in substantial savings. Both the Colorado Department of Public Health and the Environment and EPA have information and resources available to help you explore this topic.
