Mitigation Work Plans <br /> Additional Information <br /> Page 2 <br /> 3 . Surface Mill Tailings at Eureka <br /> The reason for not planning to establish vegetation as part of <br /> the project was based on a comparison to the land surrounding <br /> the remediation site. It is either a barren talus slope or an <br /> active alluvial fan. SGC proposes that the post remediation <br /> land use be similar to that of the surrounding area. This <br /> type of observation can probably be made during the first site <br /> inspection. SGC will advise DMG when the sedimentation <br /> controls are in place and upon project completion so that DMG <br /> can schedule inspections for the appropriate times. <br /> 4. Gold Prince Mill Tailings and Waste Dump <br /> SGC will inform DMG of progress on this project and of SGC's <br /> selection of a disposal site and availability of soil material <br /> for capping the material so DMG can schedule a site inspection <br /> prior to starting the waste material removal process. <br /> Attached is a copy of the old mine workings map on which SGC <br /> bases its conclusion on that water will back up approximately <br /> 15 feet before dropping into the Sunnyside Mine Pool resulting <br /> in only minor hydrostatic forces on the bulkhead. The Gold <br /> Prince portal is definitely higher than the Lake Emma outlet. <br /> SGC has not evaluated this connection but will attempt to. If <br /> the status of this connection cannot be confirmed by SGC, a <br /> pressure gauge will be installed and monitored until the <br /> reading stabilizes to provide assurance that the integrity of <br /> the bulkhead is not compromised. <br /> 5. Longfellow Koehler <br /> SGC will inform DMG of progress on this project and of SGC's <br /> selection of a disposal site, availability of soils and <br /> feasibility or plans for run on controls and ditches so DMG <br /> can schedule a site inspection prior to starting the waste <br /> material removal process. <br /> 6. Boulder Creek Tailings <br /> SGC will update DMG on project status and upon completion so <br /> that an inspection can be scheduled to determine whether the <br /> selected performance standards have been met. <br />
