12 WATER QUALITY MONITORING PLAN <br />Water quality monitoring is the best method of determining if degradation of aquifers is <br />occurring within the permit area. The testing will reveal releases, if they occur at the surface - <br />based facilities, or if mining methods are producing any changes to geologic structures or <br />underground aquifers. Geologic studies indicate that a two sample collection program will be <br />sufficient for monitoring groundwater conditions. One sample will be collected from within the <br />Lucky Strike Mine and a second sample will be collected from the Lucky Strike Mill Spring <br />(Groundwater Sampling Plan Map). <br />The groundwater testing will be performed quarterly and will continue during production. All <br />testing will be performed under the direction of a qualified individual using standard <br />procedures either produced by an engineer, or by the certified analytical laboratory. Samples <br />will be transported using standard chain of custody procedures, and the analytical laboratory <br />will analyze to MDIs that are appropriate for the maximum contaminant levels (MCLs) set by <br />the governing regulatory agency. During sampling the field crew will use clean laboratory <br />provided bottles, appropriate sampling techniques, will properly fill out laboratory provided <br />chain of custodies, and will insure that transport of the samples to the laboratory is conducted <br />using standard chain of custody procedures. <br />Following no less than three additional continuous quarters of sampling, a review will be made <br />of usefulness of the analytes tested. If individual analytes are not found to be present within <br />the permit area, the engineer may recommend removing a particular analyte or test from the <br />list. An example of an analyte that might be recommended for no further testing would be the <br />compound cyanide. Alternatively, if the engineer determines that additional testing needs to <br />be performed to properly characterize and protect the environment, then he might <br />recommend that additional analytes or tests be added. <br />The operator will submit all water monitoring reports to the Colorado DRMS by mail by the 30th <br />of the month following the end of each calendar quarter, and will retain all records for a <br />minimum of 4 years. However, it is recommended that records are retained for longer if <br />possible. The samples will be tested for the following analyties using the Methods shown <br />below. <br />15 <br />
