I <br /> Gold Prince Mill Tailings and Waste Dump <br /> Page 3 <br /> Work Plan <br /> 1) Locate acceptable area away from stream with enough soil available for cap. <br /> 2) Strip and stockpile soils. <br /> 3)Build upland diversion ditches to prevent run on conditions. <br /> 4) Build catchment ponds as needed to contain material during excavation. <br /> 5) Pick up and relocate waste and tailings to disposal area. <br /> 6)Reclaim catchment ponds. <br /> 7)Cap relocation area with salvaged soil. <br /> 8)Apply soil amendments, seed and mulch all areas disturbed during project. <br /> Analysis <br /> Consolidation, improvement of pH conditions and isolation from snowmelt and rainwater is <br /> a Best Management Practice which will prevent waters from coming into contact with the tailings and <br /> mine waste rock. Preventing water from exiting the mine portal will decrease the area drained by the <br /> adit and let the near surface water return to its natural flow paths. This project may help in reducing <br /> dissolved zinc as well as other dissolved metals in the Upper Animas Basin. <br /> Monitorina <br /> Monitoring sites will be established above and below the site for dissolved metals and continue <br /> for two years after completion of consolidation. Four sample sets will be taken yearly with one as <br /> soon as site is open in the spring and once during low flow in late fall, reports will be submitted by <br /> the 28th of the following month receipt as well as annually at the same time of SGC's Mined Land <br /> Reclamation submittal. Samples will be taken in the creek above and below the site. All samples <br /> taken will be analyzed for dissolved Zn, Fe, Al, Mn, Cd, and Cu, total sulfate, hardness and a field <br /> pH will be taken as well as field measurements for flow. <br /> Reporting <br /> Due to the short duration of this project, a report will be submitted after consolidation is <br /> completed. Results of the monitoring will be submitted by the 28th of the month following receipt <br /> and with the annual seep and spring study to both the Water Quality Control Division and the <br /> Division of Minerals and Geology. <br /> Budget <br /> SGC will fund this program. <br /> Remedial Goals and Objectives <br /> Cleanup of historic mill tailings and mine dumps with removal from contact with rainwater <br /> and snowmelt in order to reduce potential impact to the Animas River from heavy metals. <br />
