Production and processing were performed fir twelve months ot'the year. <br />Good brine grade and temperatures were noted throughout the year. The balance between <br />injection and recovery rates for cavities IA. 5H, and 6H has been continuously monitored using <br />fluid level indicators (pressure transmitters) installed in existing Dissolution Surface aquifer <br />monitoring wells located near the active cavities. <br />2008 Annual Report 6 of 28
