This report covers the <br /> period from April 1, 1999 through June 30, 1999. <br /> Terry Tunnel Bulkhead <br /> The Terry Tunnel bulkhead was inspected on June 28, 1999. During this inspection, a <br /> pressure gage was installed since the mine pool is now at this level. The pressure was <br /> 11.5 psi. In the 3`d quarter this gage and the American Tunnel gage will be checked <br /> against each other by reading them on the same day. A sample was also taken from the <br /> pool behind the bulkhead. Analytical results have not been received and will be reported <br /> with the 3`d quarter report. Field parameters were: temperature 8.4° C; conductivity <br /> 2000 umho; and pH 6.99. <br /> Inspection of the bulkhead and immediate tunnel area did not reveal any reason for <br /> concern or give any indication that the bulkhead is not performing as designed. The <br /> bulkhead valve was opened to accept pump back from the Terry Tunnel settling ponds to <br /> eliminate any potential for pond discharge. <br />
