Therefore, a final report will be submitted by the remediating party once all reclamation <br />activities aze complete as well as monthly progress reports while the project is active. <br />Reports will be sent to the DMG as well as the Division. <br />5. Mine Remediation Plan <br />Legal Rieht to Enter and Conduct Activities <br />Negotiations are in progress to obtain an agreement for this project to be implemented. <br />Remedial Goals and Obiectives <br />Reduction of metals loading to Mineral Creek by removing the artificial drain created by <br />the adit and reducing the exposure of metal beazing rock to oxygen and any chemical <br />reactions this exposure may precipitate. The project is to be completed at the earliest <br />feasible time after agreement(s) finalization but no later than September 30, 2003. <br />Site Loadine Estimate <br />The site loading estimate is based on the Animas River Stakeholder's Group's monitoring <br />data contained in the Use Attainability Analysis for the Upper Animas Basin. The <br />dissolved zinc load to Minera] Creek was estimated to be 78 pounds per day during low <br />flow and 91 pounds per day for high flow. <br />Description of Proiect <br />The tunnel timber sets will be modified for access and the tunnel inspected for sites <br />suitable for the placement of a plug. In order for a plug to be placed, a site meeting the <br />following conditions will need to be found. <br />1) Location far enough underground to avoid the near surface fractures and joints <br />caused by weathering. <br />2) Adequate rock compressive strength for structural stability. <br />3) A length of tunnel with miiumal faulting or other geologic features. <br />4) Adequate ground cover over the potential site to resist the hydrostatic forces from <br />the potential maximum head. <br />If an acceptable location can be found a plug will be designed and installed. After <br />construction of the plug is complete, the plug will be contact grouted and if penztanent <br />closure is selected by the owner, any pipes through the plug for construction purposes <br />will be grouted and the portal reclaimed. <br />Work Plan <br />1) Build catchments for potential sediment releases. <br />2) Open and evaluate tunnel for placement of a plug. <br />2) Design and install plug. <br />3) Grout seal-rock contact and piping if permanent closure is selected by the owner. <br />237115.2 December 3, 2002 B - 4 <br />
