Columbus Mine Portals <br /> Page 3 <br /> Reportin <br /> SGC will submit annual reports for this project starting with finalized engineering drawings <br /> prior to starting onsite work. Once all reclamation activities are complete, a final report will be <br /> submitted. Reports will be sent to the Division of Minerals and Geology as well as the Water Quality <br /> Control Division. The report will include activities to date as well as planned activities for future <br /> years work. <br /> Budget <br /> SGC will fund this project. <br /> Remedial Goals and Objectives <br /> Reduction of low pH, metal laden waters flowing into the West Fork of the Animas River at <br /> Animas Forks by: <br /> 1) Restoring hydrologic regime to near premining <br /> conditions. <br /> 2) Reduction of acidity in the headwaters by isolating or limiting abilities of waters to react <br /> with pyrite and other sulfide minerals. <br /> 3) Reduction of exposure to waste material by snowmelt, <br /> rainwater. <br /> 4) Visually reclaim area to accepted standards. <br /> Contingency Plans <br /> Should the concept of hydraulic seals not be practical after engineering studies, SGC will <br /> consult with the Division of Minerals and Geology for other possible solutions. If an acceptable <br /> system can be arrived at, SGC will install such a system. <br /> Catchments will be provided in order to prevent impact to the Animas River during <br /> excavation. <br /> Leeal Right to Enter and Conduct Activities <br /> SGC has not contacted the property owner. No contact will be initiated until substantial <br /> agreement is reached with WQCD concerning remediation projects. No work wifl commence until <br /> proper permission is granted. <br /> Owner: William Harvey <br />
