4-24 <br />• 4.3.5 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 4.2.3 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 consistency <br />of flow measurements. Flow measurements will also be taken at SW3, 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 in Volume I. <br />Water quality samples of East Salt Creek will be collected quarterly at sites SW-1, SW-4, and <br />SW-8 as shown on Fgure 4.2-2.1s in Volume VII. Water quality samples will also be taken on <br />Munger Creek and its tributaries at sites SW-3, SW-6, and SW7 twice a year; once during <br />spring snow melt and once during a storm event (spring or summer). Table 4.2-2s shows the <br />results of the April, 1981 laboratory analyses from East Salt Creek monitoring locations SW-1 <br />and SW-4. All water samples will be analyzed for the parameters shown in Table 2.5-2 in <br />Volume I. The results of all monitoring will be submitted to the Regulatory Authority <br />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 quarterly from 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 />• <br />Mu Volume VI 1 - 22 - 96 <br />
