June 1998 Monthly and 2nd Quarter Report <br /> Page 2 <br /> Progress pictures are included with this report for all of the <br /> sites except the Gold Prince - Mill Tailings project. While it was <br /> accessible, the site was snow covered and pictures were not taken. <br /> The pictures were taken the last of June but it was still early for <br /> vegetation especially at the Longfellow - Koehler site. <br /> - Sunnyside Mine Pool Mitigation - Alkaline Solution Injection <br /> This project was not active in June 1998 . The water pool pH, at <br /> the American Tunnel bulkhead, on June 26, 1998, was 2 . 68 and the <br /> bulkhead pressure was 351 psi. <br /> Sunnyside will continue to monitor these parameters. <br /> "B List" Projects <br /> - Columbus Mine Portals -Mine Waste Dumps <br /> - London Mine Portals - Waste Dumps <br /> Work, permitting or arrangement for access is not planned until it <br /> becomes evident that the work plans for these projects require <br /> implementation. <br /> - Cement Creek Diversion and Water Treatment <br /> Cement Creek diversion and water treatment was active <br /> continuously throughout June. The flow of Cement Creek in <br /> June remained at levels that required control on the water <br /> treatment system inlet quantity. The flow diverted and treated <br /> in June ranged from 1118 G.P.M. to 1153 G. P.M. <br /> Attached are June, 1998 monitoring results for; dissolved <br /> metals in the AT-004 discharge; Cement Creek diverted for <br /> treatment (CC-1B) ; American Tunnel flow before treatment (AT- <br /> INFEL) ; and Cement Creek below the AT-004 discharge point (CC- <br /> 20) . <br /> Mainstem Stream Monitoring and Reference Point Stream <br /> Monitoring <br /> Sunnyside sampled the reference point (A-72) on June 10, 1998 <br /> and the three mainstem gaging stations (A68, M34 and C48) . The <br /> sample results are attached. <br /> fi <br />
