  • Proposed Post-Mitigation Bathymetry
  • View of work area looking north from the work access ramp.
  • Stockpiling of EM within the Tallas Island dredge boundary area
  • Vegetation and EM removal. (Note: clear view of open water flowing into newly dredged area)
  • Vegetative root mass, EM, and ice The vegetative root mass removed from Tallas Island during the Winter Work was placed in the North and South Wetland areas and the Slip 7 Mud Flats.
  • Vegetation removal and EM stockpiling in the center of Tallas Island working toward the access ramp
  • Tallas Island vegetation removal, EM stockpiling, and live offloading of trucks (near completion)
  • Stu Russell

  • Ruben Johnson and Sons (RJS)-WI Pit Udeen Trucking, Inc.-WI Pit Burnett Aggregate-MN Pit Duluth Ready Mix (DRM)-MN Pit Ulland Brothers-MN Pit ハ
  • The USEPA (GLNPO) and XIK Corp funded ハ ( ~50%/50%) a Betterment to the SLRIDT Site Sediment Operable Unit Remedy known as the SLRIDT CAD ACM (Activated Carbon Mat) Project which was NOT a requirement of the Record of Decision (ROD). The ACM installed in the CAD provides additional protectiveness to human health, to the environment and is recognized as a New Technology. ハ
  • Sand bags were used to ballast the ACM on the previously placed cap sand, which is the 6 inches of Isolation Zone Capping Sand placed near the end of the 2009 construction season, at the bottom of the CAD. An additional 4 feet of sand cap and 6 inches of Environmental Media, from Tallas Island, was placed on top of the ACM.
