2.5.1 <br />2 5 SURFACE WATER MONITORING PROGRAM <br />A water quality monitoring program has been established to monitor the effect of mining <br />activities. Portions of this monitoring program, as well as the ground water monitoring <br />program, described in Section 2.6 will cover both the Munger Canyon and McClane Canyon <br />mines which operate in close proximity to one another in the same major watershed. Locations <br />of all surface water monitoring sites are shown on Figure 4.2-2.1s in Volume VII. <br />The quantity of flow at SW-1 will be measured quarterly, contingent upon the availability of <br />water. The design of the bridge over East Salt Creek at McClane Canyon was developed to <br />allow easier monitoring of flow. A flow rating chart has been developed to ensure consistence <br />of flow measurements. Flow measurements will also betaken at SW-3, in Munger Creek below <br />the mine site. The measurements will ideally 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 storm <br />event. Flow rating charts for both East Salt Creek and for the culvert at SW-3 are presented as <br />Table 2.5.3. <br />Water ali samples of East Salt Creek will be collected quarterly at sites SW1, SW-4,and <br />SW-8 as shown on Figure 2.3-5. Water quality samples will also be taken on Munger Creek and <br />..~ - <br />its tributaries at sites SW-3, SW-6, and SW7 twice a year; once during spring snow melt and <br />--` <br />once during a storm event (spring or summer). Table 4.5-12 shows the results of the April, <br />1981 laboratory analyses from East Salt Creek monitoring locations SW-1 and SW-4. All water <br />samples will be analyzed for the parameters shown in Table 2.5.2. The results of all monitoring <br />will be submitted to the Regulatory Authority immediately following receipt of analytical results. <br />During periods of temporary cessation, the monitoring program will be modified as follows. <br />Water quality samples will be taken quarter) fr~Om SW-3. Samples will be analyzed for those <br />parameters listed in the temporary cessation portion of Table 2.5.2. The quantity of flow will <br />be measured at SW-3 when samples are collected. <br />Mu Volume I 1 -9 -96 <br />
