112 Annual Report <br /> Standard Metals Corporation <br /> Permit No. M-77-378 <br /> Sunnyside Mine <br /> April 23, 1985Ca., ` <br /> Site: American Tunnel Portal f�$ <br /> Reference map: American Tunnel Portal Topographic <br /> Elevation: 10,480 ft to 10,600 ft <br /> Ecosystem: Subalpine, Spruce, fir <br /> Aspect: West, Southwest <br /> Affected Acreage: 11.5 acres <br /> Disturbance Type: Moderate/Major <br /> Comments: Disturbances occurring at this site include erected structures, <br /> water impoundment operations, mine equipment, storage yards, barrow acres <br /> from which impoundment dike material was obtained, and inactive mill <br /> tailings site. Affected acreage is listed as having moderate to major <br /> disturbance dependent on the extent of impact to native soils. <br /> Information Response <br /> 1. Zero acres affected during 1984. <br /> 2. Zero acres reclaimed during 1984. <br /> 3. Barrow area, see map, approximately 0.75 acre revegetated. <br /> 4. Planted with mix B, see Table #1, planted June 1981. <br /> 5. Fertilized in June 1984 with, 300 lbs of 20-0-0 per acre. <br /> 6. The appraisal of the barrow area at the American Tunnel Portal <br /> is good. This may indicate that other subsurface disturbances <br /> at this site would have the same potential for similar revege- <br /> tation in the future. Test plots utilizing similar seed mixes <br /> and fertilizers are currently planned for the inactive tailings <br /> pond and mine refuse dump this summer. <br /> 7. Zero acres to be affected in the coming year._ <br /> x <br /> Site: Decant, Animas River and Office Settling Ponds <br /> Reference map: Mill Tailings Pond and Office <br /> Elevation: 9,340 ft to 9,420 ft <br /> Ecosystem: Intermountain, Aspen <br /> Aspect: Southeast <br /> Affected Acreage: 15.7 acres <br /> Disturbance Type: Moderate/Major <br /> Comments: The disturbance primarily consists of a series of small impound- <br /> ments constructed with earthen dikes for use as mill tailings deposition <br /> sites on an interim basis while site preparation activities for the entire <br /> tailings impoundment No. 4 were completed. Acreages affected at this site <br /> are listed as having moderate to major disturbances resulting from limited <br /> mill tailings deposition, water impoundment operations and temporary heavy <br /> metals hydroxl sludge storage. <br />
