Future Hvdrolooic Monitorinq <br />A continuous flow meter will be installed on the flow from spring <br />5-31 to provide accurate monitoring of flows from this key spring. <br />Springs 5-30, SP13-5, and SP85, and Pond P13-7 are also included in <br />the current monitoring program. However, much of the hydrologic <br />data collected has little utility or relevance for monitoring <br />mining impacts. Flow from most of the springs and ponds is too low <br />to be of any significance for water supply for stock or wildlife <br />and have virtually no affect on the water quality or quantity in <br />there respective drainages. Re-evaluation of the current <br />monitoring program in light of observed and potential impacts and <br />current mine plans is in order to better focus the monitoring <br />• program. <br />Monitoring of springs and ponds that are located outside the angle <br />of draw of recent (prior 3 years) or future (next 3 years) provide <br />little or no information concerning potential mining impacts. <br />Although no significant impacts on the hydrology from subsidence <br />have been observed; it is possible that subsidence could reduce (or <br />increase) spring flows or dewater ponds. However; no impacts on <br />water quality would be expected. <br />In order to rationalize the hydrologic monitoring program Cyprus <br />Orchard Valley Coal Corporation makes the following proposals: <br />Water quality data should only be collected at selected springs. <br />• Only those springs which discharge continuously throughout each <br /> summer should be sampled. Only flow rate should be collected from <br />21 <br />
