Site Reclamation Activity <br /> April 1996 - March 1997 <br /> Page 10 <br /> Monitoring of the bulkhead pressure gage in the American Tunnel was <br /> performed more often than required by TR-14. As of March 31 , 1997, <br /> the pressure was 252 psi which reflects a pool surface elevation of <br /> 11 , 232 feet MSL. During each monitoring visit, the tunnel and <br /> bulkhead are inspected for changes. No changes have been noted to- <br /> date. <br /> The Terry Tunnel bulkhead was last inspected in October, 1996 when <br /> the site was shut-down for the winter. Bulkhead pressure will be <br /> constant until the mine pool rises above 11 ,600 feet MSL. No <br /> problems were observed at this bulkhead when the valve was shut and <br /> site closed down for the winter. <br />
