Subsequent to issuance of the initial permanent regulatory program permit, the operator <br />implemented a plan for the collection, recording and reporting of surface water quality and <br />quantity data. The program consists of surface water monitoring above and below the <br />disturbance in the Munger Canyon tributary, along Munger Canyon before the confluence <br />with East Salt Creek and along East Salt Creek upstream and downstream of the confluence <br />with Munger Canyon. This monitoring plan will be sufficient to identify any effects of the <br />operation on the surface water hydrology. The hydrology monitoring program for the <br />Munger Canyon Mine is in part combined with the monitoring program for the adjacent <br />McClane Canyon Mine, which is also operated by CAM, and data collected at several of the <br />sites fulfills monitoring requirements for both permits. A combined Annual Hydrology <br />Report with sample data, summaries, and impact assessment for each mine is submitted by <br />March 31 of each year, covering the previous water year. <br />The operator has committed to the following surface water monitoring program: <br />1) Flow measurements will be taken at surface water monitoring sites SW-1, upstream <br />from the mine on East Salt Creek, and SW-3, in Munger Creek downstream from the <br />mine site. The measurements will be taken twice a year if water is available to <br />sample. Measurements will be taken once during spring snow melt and once during a <br />storm event. <br />2) Water quality samples of East Salt Creek will be collected quarterly at sites SW-1, <br />SW-4 and SW-8. SW-8 is located between McClane and Munger Canyons on East <br />Salt Creek. SW-4 is located downstream of the confluence of Munger Creek on East <br />Salt Creek. Water quality samples will also be taken on Munger Creek and its <br />tributaries, at sites SW-3, SW-6 and SW-7 twice a year; once during spring snow melt <br />and once during a storm event (spring or summer). <br />3) Surface water samples will be chemically analyzed for the 23 parameters specified in <br />the "Full Suite For Active Mining List", in Table 2.5-2 of the permit application. <br />4) The results of all monitoring will be submitted to the Division immediately following <br />receipt of analytical results. Monitoring results and summary, along with a report <br />addressing mine inflows, discharges, and consumption in the mine will also be <br />included in an annual hydrological report submitted each year, structured around the <br />normal "water year" (October 1 through September 30). <br />5) During periods of temporary cessation of operations at the Munger Canyon Mine, <br />items 1, 2, and 3 listed above are modified as follows: Water quality samples will be <br />limited to quarterly samples from SW-3. Surface water samples will be analyzed for <br />the 8 parameters listed in the "Short Suite For Temporary Cessation List", in Table <br />2.5-2 of the permit application. <br />Ground Water <br />24
