A copy of CDMG's letter is attached. After your site visit,I <br /> understand that you believe the activities should enable meeting Outfall 016's effluent limitations at Outfall 025 <br /> The Water Quality Control Division("WQCD") approves of this temporary discharge of mine water through <br /> Outfall 025,provided Mid-Continent ensures the effluent is sampled twice/week during the discharge for the <br /> parameters specified in the permit for Outfall 016. Please collect the first sample within 24 hours of commencement <br /> of the mine water discharge through Outfall 025. When submitting the data to the WQCD with the appropriate <br /> Discharge Monitoring Report,please indicate the duration of the diversion and of mine water discharge through <br /> Outfall 025 and summarize the analytical results. Please be advised that the effluent from Outfall 025 will be <br /> expected to meet Outfall 016's effluent limitations during the diversion. Should any exceedences occur,please <br /> advise the WQCD within 24 hours and provide a noncompliance report, as defined in the permit. <br /> Thank you for your assistance and cooperation in this process.
