Parameters to be sampled <br />at surface water sites <br /> <br />Table 2.04.7-1 PAP All required parameters appear to have been <br />analyzed. <br />13. Filing frequency of pond <br />reports <br /> <br />CDRMS regulation <br />4.05.9(17) <br /> <br /> <br />14. Timely filing of pond <br />reports <br /> <br />CDRMS regulation <br />4.05.9(17) <br /> <br />Quarterly pond inspection reports were submitted <br />and received by the Division within an appropriate <br />timeframe. <br /> <br />15. Content of pond reports <br /> <br />CDRMS regulation <br />4.05.9(15) <br /> <br />The annual impoundment inspection reports are <br />required to include the information required by Rule <br />4.05.9(15). The report forms for each impoundment <br />includes a checklist regarding erosion, instability, <br />structural weaknesses and items that may be <br />considered hazardous. <br /> <br />For all of the impoundments, in accordance with <br />Rule 4.05.9(15), the report is required to discuss : <br /> <br />b) Existing and required monitoring procedures and <br />instrumentation. <br />c) The depth and elevation of any impounded waters <br />at the time of the certified report. <br />e) Existing storage capacity of the impoundment. <br /> <br />16. Sampling frequency of <br />ground water monitoring wells <br /> <br />Table 2.04.7-1 PAP The permitted sampling frequency was in compliance <br />at all ground water monitoring sites. <br /> <br /> <br />17. Parameters to be analyzed <br />in ground water samples <br /> <br />Volume 1, p. 2.04-105 <br />of CDRMS mining <br />permit C-2009-087 <br /> <br />All required parameters appear to have been <br />analyzed. <br /> <br /> <br />18. Basic Standards for <br />Ground Water <br /> <br />CWQCC regulations <br />41.4 and 41.5 <br /> <br />The Burro Canyon Formation, approximately 60 ft <br />below mining, may be the only target for local water <br />supply wells. This formation is not believed to be in <br />communication with mining. Prior mining or <br />naturally high concentrations of sodium and sulfate <br />make water within communication with mining units <br />unusable for domestic or irrigation, and marginal to <br />unusable for livestock. <br />19. Restoration of ground <br />recharge to approximate pre- <br />mining rate <br /> <br />CDRMS regulation <br />4.05.12(3) <br /> <br />Water levels appear to be stable or increasing. <br /> Please provide water elevation summary <br />graphs and discussion to future AHRs
