Site Reclamation Activity <br /> April 1996 - March 1997 <br /> Page 4 <br /> SUNNYSIDE BASIN (LAKE EMKA) AREA - Plate No. 2 <br /> During the 1996 reporting year, no additional acreage was disturbed <br /> or reclaimed. TR-20 was submitted and approved to eliminate <br /> subsidence monitoring as a permit requirement for the now reclaimed <br /> open-pit highwall areas. <br /> Activity at the site consisted of; <br /> 1) refilling the area of subsidence over the Lake Emma hole back <br /> to grade. The fill material was obtained from the stockpile <br /> left for this purpose. <br /> 2) injection of alkaline material into the mine pool after loss <br /> of adequate source water at the Terry Tunnel site. Injection <br /> was through an adit into a vent raise above the main ore pass. <br /> This allowed distribution into the main water conduit of the <br /> mine. This alternate site was approved in TR-19. <br /> Planned activity for 1997 includes; <br /> 1) refilling to grade any subsidence of the Lake Emma backfill. <br /> 2) monitoring and maintenance of the planted areas. <br /> 3) construction of safety barriers around or over a historic <br /> stope on the north side of the permit area. This work was <br /> tentatively planned for 1996 but work schedules and manpower <br /> did not allow it to happen. <br /> 4) alkaline injection into the mine pool if the project is <br /> extended into the 1997 season. <br /> TAILINGS POND 14 - Plate No. 3 <br /> During the 1996 reporting year no additional acreage was disturbed <br /> and an additional 9 .00 acres were placed in the reclamation in <br /> progress category. <br /> Reclamation activity at this site consisted of; <br /> 1) usage of this site to contain material removed from the <br /> American Tunnel settling ponds, Terry Tunnel settling ponds <br /> and Consent Decree - Mine Remediation Projects. Material from <br /> the Eureka Tailings project and Koehler waste dump were placed <br /> in Tailings Pond #4. Portions of the northeast and east sides <br /> were brought to a final sub-grade elevation with this <br /> material. <br />
