1. Measure and record static water levels in the Times Mine well and the Wynona Mine <br /> shaft. <br /> 2. Start the Gould's Model 85GS pump currently installed in the Wynona Mine shaft. <br /> 3. Establish a steady water flow rate from this pump. <br /> 4. Measure and record water flow rates,totalized volumes and water levels in both the <br /> Times Mine well and the Wynona Mine shaft well every five (5) minutes and <br /> document these flow rates, totalized volumes, and water levels. <br /> 5. The data from the pump test would then be used to create a mine pool elevation to <br /> capacity curve. Along with the pump test data, this curve would be used to develop <br /> a mine drawdown plan. <br /> 6. The pumping test should help establish the elevation of the Wynona Mine 100 Foot <br /> Level, which will assist in determining the water volume above the Times Mine <br /> workings. <br /> 7. Water pumped from the Wynona Mine shaft well will be pumped into the two steady <br /> head tanks located inside the Gold Hill Mill, where a totalizing flow meter will be <br /> installed to measure the discharge from the Wynona Mine shaft well. <br /> 8. All of the mine water collected in the two steady head tanks will be contained in the <br /> large thickener tank located on the Flotation Level inside the Gold Hill Mill, which <br /> has the capacity to hold more than 50,000 gallons of water. <br /> 9. The Times Mine Bulkhead pressure gauge will be monitored on a predetermined <br /> basis to determine the effects of different water levels in the Times and Wynona <br /> Mines on the bulkhead pressure. The results obtained from these observations will <br /> help determine the actual amount of water that needs to be pumped from the <br /> underground mine workings to control the bulkhead pressure. <br /> 10. No mine water will be discharged during the pump test. Therefore, a discharge <br /> permit from the CDPHE and the WQCD will not be required to conduct this pump <br /> test. <br /> b. Because the site is still under a Temporary Suspension by the BLM, please commit to <br /> demonstrating to the Division, prior to initiating the pumping test, that the BLM has authorized <br /> this activity to occur at the site. <br /> CMC Response: CMC commits to demonstrating to the DBMS, prior to initiating the pumping <br /> test, that the BLM has authorized this activity at the Gold Hill Millsite. Based upon previous <br /> communications between CMC and the BLM, it does not appear that the BLM will not authorize <br /> 2 <br />
