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 <br />selection of a disposal site, <br />feasibility or plans for run on <br />can schedule a site inspection <br />material removal process. <br />6. Boulder Creek Tailings <br />on this project and of SGC's <br />availability of soils and <br />controls and ditches so DMG <br />prior to starting the waste <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 />
