Boulder Creek Tailings Project <br /> Page 2 <br /> Work Plan <br /> 1) Remove old tailings starting at the uphill side and move downhill towards the Animas <br /> River. <br /> 2) Relocate the tailings to Tailings Pond #4 at the Mayflower Mill and mix with pH <br /> neutralizing material. <br /> 3) Regrade area to blend in with surrounding topography. <br /> 4) Add soil amendments as necessary, seed and mulch. <br /> Analysis <br /> Removal and consolidation from rain and snow melt is a Best Management Practice. This will <br /> isolate the material from direct contact with stormwater events and reduces the risk for potential <br /> impact to the Animas River and Boulder Creek. <br /> Monitoring <br /> Due to the close proximity and the high flow which occurs in the Animas River no monitoring <br /> is contemplated for this project. <br /> Reportin¢ <br /> Notification at start of project with final report after completion of project. The final report <br /> will be written after completion of activities and will include cubic yards moved, amount of <br /> neutralizing material used and soil amendments used. Monitoring reports, if any monitoring is done, <br /> will be included with the annual seep and spring study and sent to both the Water Quality Control <br /> Division and the Division of Minerals and Geology. <br /> Bu—T <br /> SGC will fund this project unless the property owner chooses to contribute. <br /> Remedial Goals and Obiectives <br /> Cleanup of historic tailings and'removal from contact with rainwater and snowmelt in order <br /> to reduce potential impacts to the Animas River from dissolved metals and mineralized sediment. <br />
