COLORADO DEPARTMENT' OF HEALTH, Water Quality Control Division <br />Rationale -Page 28, Permit No. CO-0043648 <br />(4J an analysis of the groundwater data that has been collected during the year, providing a determination <br />as to whether or not; (aJ there has been any discharge of pollutants to groundwater, and (bJ there is <br />any potential for such pollutants to reach surface waters of the State. <br />(3J a copy of al[ stream data submitted to the Division of Minerals and Geology in compliance with the <br />DMG mining permit. <br />3. Special Reports -Special reports are required in the event of a spill, bypass, or other noncompliance. Please <br />refer to Part 1, Section D.4. of the permit for reporting requiremems. <br />D. Additional Terms and Conditions <br />1. ~natorv Rettuirements -Signatory requiremenu for reports and submittals are discussed in Part /, Section <br />D. 1. of the permit. <br />Z. Catnoliance Schedules <br />a. Movement and Treatment of Carlton Mill Tailines: The perntittee shall remove the Carlton Mill <br />Tailings from their present location, and provide whatever treatment is required to limit cyanide <br />concentrations to in any seepage from the tai/lags in their new location to levels which wit! not exceed <br />the detection limit for WAD cyanide of 0.030 mg!! in any surface water for which the free cyanide <br />standard of 0.005 mg/l has been adopted. The movement and treatment of the tailings shall be <br />completed by June 30, 1995. <br />b. Materials Containment Plan: The perminee will be required to submit a Materials Containment Plan. <br />The plan shall address [he prevention and containment of spills of materials used, processed or stored <br />at the facility which, if spilled, would have a reasonable probability of having a visible or otherwise <br />detrimental impact on waters ojthe State. This plan is to be submitted within 90 days of the effective <br />date of the permit. See Pan 1. E. of the permit. <br />E. Waste Minimization/Pollution Prevention <br />Waste minimization and pollution prevention are two terms that are becoming increasingly more conv»on in <br />industry today. Waste minimization includes reducing the amount of waste ar the source through changes in <br />industrial processes, and reuse and recycling of wastes for the original or some other purpose such as <br />materials recovery or energy production. Pollution prevention goes hand-in-hand with waste minimization. /f <br />the waste is eliminated at the front of the line, it will not have to Ge treated at the end of the line. The direct <br />benefits to the industry are often sign cant -both in terms of increased profit and in public relations. <br />This progrnnt can affect n(t areas of process and waste control with which your industt~~ deals. Elimination or <br />reduction ojn wastewater pollutant can also result in n reduction of an air pollutant or a reduction in the <br />amount of hazardous materials that you have to handle andlor dispose of. <br />Tito discharge permit does not spec~calty dictate waste minimization conditions nt this time. We strongly <br />encourage the permitree to develop a waste minimization plan. Several industries have already developed <br />plans and found that implementation resulted in substantial sayings. Both the Colorado Deparmtenr of Health <br />and EPA !rave information and resources available to help you explore this topic. <br />Rich Horstmnnn <br />September 23, 1944 <br />
