Memo to Bill Goodhard <br />whether or not revegetation efforts would be appropriate for any of <br />the land affected by this project may be made in consultation with <br />DMG at a point in time near the end of the tailing removal project, <br />based on site specific observations. An inspection of sedimentation <br />controls during the tailing removal project may also be appropriate. <br />4. The work plan detailing relocation of the Gold Prince Mill Tailings <br />and Waste Dump provides the basic information necessary to allow DMG <br />to inspect the site and make a determination as to whether or not <br />the project has been completed and meets the requirements of the <br />selected performance standards. It is suggested that a site <br />inspection may be appropriate during the mitigation project to <br />facilitate DMG's concurrence with the disposal site selected, and to <br />evaluate the soils available at the selected disposal site for <br />capping of the relocated waste rock and tailing. Also, it is DMG's <br />understanding that the modifications to the existing Gold Prince <br />Mine closure in order to make it a water impounding closure, will <br />essentially result in establishment of a non - structural bulkhead. <br />It is also DMG's understanding that available mine maps indicate <br />that only a small amount of hydrostatic head (approximately 15 feet) <br />would build behind the non - structural bulkhead before the impounded <br />water would spill into the Sunnyside Mine workings. Please report <br />on the feasibility of monitoring the pressure head behind the Gold <br />Prince bulkhead to provide assurance that unanticipated pressures <br />that may threaten the integrity of the bulkhead are not developing. <br />5. The work plan detailing construction of run on control measures and <br />mine waste relocation at the Longfellow Koehler site provides the <br />basic information necessary to allow DMG to inspect the site and <br />make a determination as to whether or not the project has been <br />completed and meets the requirements of the selected performance <br />standards. It is suggested that a site inspection may be <br />appropriate during the mitigation project to facilitate DMG's <br />concurrence with the disposal site selected, to evaluate the soils <br />available at the selected disposal site for capping of the relocated <br />waste rock, and to evaluate the feasibility of run on controls. It <br />may also be appropriate for DMG to review the designs for proposed <br />lined diversion ditches prior to their installation. <br />6. The work plan detailing removal of Boulder creek Tailings provides <br />the basic information necessary to allow DMG to inspect the site and <br />make a determination as to whether or not the project has been <br />completed and meets the requirements of the selected performance <br />standards. <br />7. The work plan detailing relocation of the pride of the West Tailings <br />provides the basic information necessary to allow DMG to inspect the <br />site and make a determination as to whether or not the project has <br />been completed and meets the requirements of the selected <br />performance standards. • Relocation of the tailing to the <br />
