Page 3 Site: Inactive Tail Pond No. 3 Reference map: Mill, Tailings Pond and Office Elevation: 9,416 ft to 9,470 ft Jjt' i'`a ji Ecosystem: Intermountain, Aspen Aspect: Southeast Affected Acreage: 9.5 acres �� Disturbance Type: Major Comments: Acreage affected at this site is listed as having major dis- turbance resulting from mill tailings deposition practices conducted by Standard Metals Corporation. This tailings disposal site is differ- entiated from other tailings sites in that the impoundment embankment was constructed from native soils adjacent to the site as opposed to segregated tailings material. Disturbance at the site is therefore comprised of barrow areas as well as the displacement of native soils by tailings. As of this time the Town of Silverton has leased this site for use as a municipal dump, which is no longer active. At the present time Standard Metals Corporation is not responsible for this site. Site: Inactive Tail Pond No. 2 Reference map: Mill, Tailings Pond and Office Elevation: 9,500 ft to 9,700 ft Ecosystem: Intermountain, Aspen Aspect: Southeast Affected Acreage: 21.6 acres Disturbance Type: Major Comments: Acreages affected at this site are listed as having major dis- turbance resulting from mill tailing deposition practices. The majority of the disturbance occurred prior to Standard Metals Corporation activity in the area and includes displacement of native topsoil and subsoils with mill tailings, producing an area inhibitory to plant establishment, and growth. Information Response 1. Zero acres affected during 1984. 2. Zero acres reclaimed during 1984. 3. Approximately 11.48 acres in various stages of revegetation and another 5 acres in various stages of grading. 4. The vegetation planted is predominantly mix C and mix D with various other species being introduced by the S.C.S. Planting started on this pond in 1976 and has continued through last summer. 5. All revegetated areas received approximately 300 lbs of 20-0-0 fertilizer per acre in 1984. 6. The appraisal of reclamation efforts on the slopes of the tailings pond may be considered good. The appraisal of reclamation efforts on the top of the pond may be considered fair to poor. The suspected causes for the poor appraisal of the top of the ponds may be acidic soil conditions, toxic soil conditions, infertile soil conditions and extreme environmental weather conditions. 7. Zero acres to be affected in the coming year.
