2.6 Ground Water Monitoring <br />A water quality monitoring program has been established to monitor the effects of the McClane <br />Canyon and Munger Canyon mines on ground water in the area. The ground water monitoring <br />program will consist of the following observations, measurements and sampling: <br />1. Quarterly monitoring of wells, GW -1 and GW -3 for Static Water Level, pH, Temperature, and <br />Specific Conductance. <br />2. Water quality sampling of mine water discharges as required by CDPS permit. <br />3. Monitoring of all non -seep inflows into the mine to include source, quantity, duration and <br />quality (pH, Electrical Conductance, and Temperature). <br />4. Monitor quantities of water discharged from the mine, consumed in the mine, and imported <br />for use in the mine. <br />Results of the quarterly ground water monitoring shall be submitted to the Division immediately <br />after data collection and analysis except during temporary cessation. Results of additional <br />monitoring will be submitted to the Division in an annual hydrological report. The annual report <br />will detail inflows, discharges and consumption of water within the mine and shall be structured <br />around the normal "water year" (October 1 through September 30). <br />Water samples will be collected with a bailer after the depth to water table has been measured. All <br />monitoring wells shall be pumped at least once a year and prior to sample collection with an air lift <br />or a bailer. <br />Monitoring well GW -6, as shown on Figure 2.3-5, was installed and has been sampled as required <br />prior to the construction of the Munger Canyon Waste Rock Pile. Water quality samples shall be <br />taken and water levels established quarterly. Analysis will be for the above noted parameters. <br />On March 20, 1984 the Division approved a revision to sample GW -5 in Munger Canyon only during <br />the period of temporary cessation. Since GW -5 has been dry since installation, well GW -3 was <br />substituted and monitored quarterly for Static Water Level, pH, Temperature and specific <br />Conductance. <br />Since both GW -5 and GW -6 have been dry during all monitoring events, they will be sealed during <br />2016. <br />Monitoring well GW -7 is located at a location where the Operator once proposed a coal mine waste <br />disposal area. GW -7 was first noted to contain water in 1987. The conductivity of the water was in <br />excess of 100,000 umhos/cm. <br />The Location of GW -3 on Figure 2.3-5 changed slightly, based on GPS data gathered February 10, <br />2006. Right of entry for GW -3 & GW -5 is presented in Appendix C, Exhibit 3. GW -2, 4, 7 and 8 were <br />sealed in 2007. <br />TR -27 2-30 07/16 <br />
