Ransom Mine Portal <br /> Page 4 <br /> Work Plan <br /> 1) Build catchments for potential adit releases. <br /> 2) Open and evaluate adit for hydraulic seal. <br /> 2) Design and install hydraulic seal. <br /> 3) Grout seal-rock contact and bypass pipe. <br /> 4) Portal closure <br /> Analysis <br /> The hydraulic seal proposed for the Ransom adit will reduce the unsaturated zone by <br /> removing the drain This will result in minimizing the oxygen available for reaction with the sulfide <br /> materials in the area The hydrological conditions will be restored to an approximation of pre-mining <br /> conditions and should improve the water quality in the area. <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 /> Monitoring <br /> Additional monitoring for this project is not contemplated. SGC monitors the South Fork of <br /> the Animas River at the mouth of Eureka Gulch during low flow twice annually as a MLR Permit <br /> requirement This monitoring station is just below the point where portal flows would enter the <br /> South Fork of the Animas. SGC will maintain this monitoring station until released from this <br /> requirement. <br /> Budget <br /> SGC will fund this project. <br /> Description of Land Use <br /> This remediation work plan is intended to use Best Management Practices on the site to <br /> conform with surrounding land use policies for; <br /> 1) land stabilization, limited rangeland and wildlife habitat to approximately resemble a <br /> mountain park ecosystem consistant with bordering undisturbed areas. <br /> 2)the conversion of facilities, usable for purposes for other than mining, to alternate uses and <br /> preserve facilities of historic interest <br />
