This report covers <br /> the period from October 1, 1996 through December 31, 1996. <br /> Terry Tunnel Bulkhead <br /> The Terry Tunnel bulkhead valve was closed upon site <br /> demobilization. Fluid injection was suspended on October 9, 1996 <br /> due to weather conditions at the site. This site will be <br /> inaccessible until around June 1, 1997. The mine pool elevation <br /> was still below 11,600' elevation on December 31, 1996 therefore, <br /> bulkhead pressure should be at 8 psi . <br /> American Tunnel Bulkhead <br /> The American Tunnel bulkhead was inspected, gage pressure readings <br /> taken and fluid samples analyzed for pH, conductivity and <br /> temperature more frequently than the requirements of Items 3. and <br /> 4. in the Rule Authorization letter. This information is attached. <br /> The American Tunnel bulkhead valve has remained closed since <br /> closure on September 9, 1996. <br /> Site inspections have not revealed any indication that the bulkhead <br /> is performing other than as designed. <br />
