Notify the BLMand the EPA, within the next BI,M working day, that the corrective <br />action sequence ofproceduresfnr change in hydrostaticpressure at the Dissolution <br />Suuface has been implemented. <br />2. Evaluate the integrity of the pressure transducer. <br />3. Evaluate other Dissolution Surface hydrostatic monitoring systems. <br />4. Evaluate the mass balance of the production wells in the azea. <br />5. Discontinue injection into the solution mining well and balance the density of the <br />fluids in the well. <br />6. Pressure test all tubing, strings, and annular areas between well strings with nitrogen <br />gas to hydrostatic pressure to ensure the mechanical integrity of the tubing. <br />7. Perform a temperature log to determine if there is any significant tempernture change <br />above the aahcolite-bearing wne. ' <br />8. Evaluate the results from these procedures to determine the best solution for <br />wrrecting the problem. The use of additional logging techniques may be required <br />to accurately pinpoint any mechanical failures. <br />9. Notify the BLM and EPA of the results of the evaluation and the proposed cortective <br />actions to be taken. <br />6.9.3 ProcesslVlanitoring <br />Ifchanges in physical parameters at the production stream indicate aformation failures cavity <br />breach, or production well breach. The BLM and EPA will be notified within the next BLM working <br />day, and the following procedures will be initiated. <br />1. The well pressure, temperature and flow rate instrumentation will be checked for <br />accuracy. <br />2. The wel! valves will be checked for possible leakage. <br />3. injection into the solution mining well will be discontinued and the density of the <br />fluids in the well will be balanced. <br />Agapito Associates, Inc. <br />
