APPLICATION for DISCHARGES ASSOCIATED WITH HARDROCK MINING AND /OR MILLING <br />26. Whole Effluent Toxicity Testing: WET testing shall be conducted for each outfall which is not solely made up of <br />stormwater or domestic wastewater, unless waived by the Division, on 100% effluent using both Ceriodaphnia dubia and <br />fathead minnows. This requirement is waived where routine testing is currently required under an existing CDPS permit. The test shall <br />be an acute test unless the ratio of stream low flow to effluent design flow is less than 10:1, respectively, and the receiving stream has <br />a Class 1 Aquatic Life Use or Class 2 Aquatic Life Use with all the appropriate aquatic life numeric standards. In the latter case, a <br />chronic test is required. The Division reserves the right to request additional testing as part of the application review process. If so <br />required, the permit application will not be considered complete until the additional testing is submitted. In addition, all applicants must <br />identify any biological toxicity tests which have been performed within the last 3 years on any of the discharges or the receiving water <br />in relation to a discharge from this facility. Attach WET test results <br />to this application.lf so required, the permit will not be processed until the additional information is submitted. <br />WET testing procedures are described in the "Guidelines for Conducting Whole Effluent Toxicity Tests" which can be <br />obtained from the Division. <br />27. Priority Pollutant Scan: The results of a priority pollutant scan, unless waived by the Division, for the volatile and acid fractions as <br />shown in Appendix A must be submitted of each discharge. <br />28. Additional Monitoring: All applicants must review the parameters listed in Appendix A and Appendix B to this application, and <br />indicate whether it knows or has reason to believe that these pollutants are present. For every pollutant expected to be discharged, <br />the applicant must briefly describe the reasons the pollutant is expected to be discharged, and report any quantitative data for the <br />pollutant. <br />None of the parameters listed in Appendix A and B are expected to be discharged. <br />29.. Please submit a copy all water quality monitoring data of outfalls or receiving streams for which data has been gathered over the last <br />five years for the mining /milling site and which is required by the Division of Minerals and Geology. If not already submitted to the <br />Division, the plan which details the monitoring frequency, type, locations and method of analysis must also be submitted. <br />30. Stormwater Discharges: All active and inactive mineral mines and mills must be covered by a stormwater permit. Please complete <br />Appendix B and submit along with the application. (Note: Appendix C is an EPA form titled, Application for Permit to Discharge Storm <br />Water, Discharges Associated with Industrial Activity.) Additionally, new mines /mills must submit a copy of their Stormwater <br />Management Plan with the application. <br />31. Pollution Prevention Plans: Please describe any pollution prevention or best management plans currently currently in place which <br />could result in the improvement of water quality. These could include solvent recycling programs, material containment procedures, <br />education, etc. <br />N/A <br />36. Historic Drainages: Does historic drainage exist at the site, which is not covered under a CDPS permit? Yes ?� If so, please <br />provide a map showing the location of the discharges and copies of all analytical information on the discharges. Please sample the <br />discharges for the parameters listed in item 26 and submit those results. This requirement may be waived by the Division if suitable <br />data on the discharges historic quality and quantity exists. <br />No. <br />Revised 4/2011 <br />
