spillway inlet. D. Surface and Ground Water Monitoring Surface Water The surface water monitoring program is addressed in Section 2.5 of the application text, parameter list is presented in Table 2.5-2, and monitoring site locations aze shown on Figure 2.3-5. Adequate baseline data indicating characteristics of water quantity and quality for East Salt Creek in the vicinity of Munger Canyon and for the drainage in Munger Canyon was provided in the original permit application, summarized in Section 4.5 of the application text. Total dissolved solids in East Salt Creek have been noted over a range of 600 mg/1 to 10,000 mgfl. Water is typically a sodium sulfate type. In Munger Creek, like most semi-arid ephemeral drainages, dissolved constituents in surface water often reach high levels during storm runoff. Dissolved solids measured in Munger Canyon ranged from 92 mgll in December to 956 mgll in April. Subsequent to issuance of the initial permanent regulatory program permit, the operator implemented a plan for the collection, recording and reporting of surface water quality and quantity data. The program consists of surface water monitoring above and below the disturbance in the Munger Canyon tributary, along Munger Canyon before the confluence with East Salt Creek and along East Salt Creek upstream and downstream of the confluence with Munger Canyon. This monitoring plan will be sufficient to identify any effects of the operation on the surface water hydrology. The hydrology monitoring program for the Munger Canyon Mine is in part combined with the monitoring program for the adjacent McClane Canyon Mine, which is also operated by CAM, and data collected at several of the sites fulfills monitoring requirements for both pemuts. A combined Annual Hydrology Report with sample data, summaries, and impact assessment for each mine is submitted by Mazch 31 of each year, covering the previous water year. The operator has committed to the following surface water monitoring program: 1) Flow measurements will be taken at surface water monitoring sites SW-1, upstream from the mine on East Salt Creek, and SW-3, in Munger Creek downstream from the mine site. The measurements will be taken twice a year if water is available to sample. Measurements will be taken once during spring snow melt and once during a storm event. 2) Water quality samples of East Salt Creek will be collected quarterly at sites SW-1, SW-4 and SW-8. SW-8 is located between McClane and Munger Canyons on East Salt Creek. S W-4 is located downstream of the confluence of Munger Creek 23
