Page 4 <br /> Bond And Acreage Reduction Submittal <br /> Reclamation: <br /> Refuse and trash has been removed from the site or buried on-site. Some of the <br /> slopes have been regraded, amended with limestone and/or topsoil, and seeded <br /> with the alpine mix. Vegetation is starting to become established on some of these <br /> slopes. The mine waste dump in Eureka Creek was graded so that the creek <br /> could flow freely without backing up against the historic waste dump. The tunnel <br /> bulkhead has been placed to prevent mine drainage from flowing to surface via the <br /> tunnel. <br /> Pond removal, portal backfilling and final site contouring remains to be completed <br /> at this site. Upon determination that water treatment at this site will not be <br /> required in the future, these items can be completed for final site reclamation. <br /> EUREKA STAGING AREA <br /> This area was released from the permit area in 1994. A corresponding bond reduction <br /> was not requested. <br /> AMERICAN TUNNEL <br /> Proposed acreage changes: (see attached land map for detail) <br /> Existing Permit Acreage 28.01 <br /> Permit Area Reduction Proposed 5.96 <br /> Proposed Permit Area 22.05 <br /> Activity: <br /> The American Tunnel site, during operations, served as the main entry into the <br /> Sunnyside Mine workings. Ancillary surface facilities included warehouse and <br /> office facilities, change room, maintenance shops, ore storage area, waste dump, <br /> and water treatment facilities. After operations ceased in 1991, these ancillary <br /> facilities were reduced to the level required to provide support for reclamation <br /> activities and water treatment. <br /> After construction of the American Tunnel bulkhead in 1995 and subsequent valve <br /> closure in 1996 JR- 014), a diversion was constructed to facilitate diversion and <br /> treatment of Cement Creek for an interim period of time while performing <br /> projects in the Animas River Basin (TR- 019). This interim treatment of Cement <br /> Creek is a condition in the voluntary Consent Decree agreement between <br /> Sunnyside and CDPHE - WQCD (TR- 014). The Consent Decree agreement <br />
