Boulder Creek Tailings Project <br /> Page 2 <br /> Site Loading Estimate (cont.) <br /> Based on these assumptions and procedures, SGC estimates that the average daily loading for <br /> this site may be as much as 7.5 pounds of dissolved zinc per day. SGC is under no obligation to <br /> defend these estimates and they should only be used as an estimate. SGC does not represent that its <br /> mitigation project at this site will remove any specific percentage of metals loading from this site: the <br /> loading estimate contained herein does not form the basis of an enforceable permit obligation. <br /> Description of Project <br /> The tailings are dry through most of the year except during high rain events and snowmelt. <br /> The pond will be removed from the uphill side and hauled to SGC's Mayflower Tailings Pond #4. <br /> Under Sunnyside Gold's MLR Permit (M-77-378) this material can be consolidated into Tailings <br /> Pond # 4. The pH of the tailings will be adjusted by mixing with high pH material during <br /> consolidation. The tailings will be capped and planted as part of SGC's approved reclamation plan <br /> for Tailings Pond #4. The soil at the project site will be tested for necessary amendments, then <br /> seeded and mulched. This plan is subject to notification requirements for disturbance of Historical <br /> Mining Sites to the board of the San Juan County Commissioners.. <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 /> Reporting <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 />
