    1. Case Study: Open Water Disposal of Dredged Materials in the Great Lakes Basin

    2. Open Water Disposal

    3. Open Water Disposal Minnesota Duluth Superior Harbor DMMP Placement in 5 deep holes vs. habitat enhancement Wisconsin Beneficial use in water permitted Bulkhead lines/ submerged land lease Last resort: deep hole filling and deep water dumping Direct legislation needed

    4. Open Water Disposal Ohio 401 water quality certification: Open water disposal phase-out USACE/OEPA appeals process Michigan Executive Order No. 2004-1 Beneficial use is preferred

    5. Open Water Disposal Conclusions Identify beneficial uses and remove regulatory barriers Secure funding streams for beneficial use options Burden of proof when the Federal Standards does not meet state water quality/environmental standards

    6. Case Study: Barging Illinois River sediment to Chicago reclamation site Problem: Sedimentation in Peoria Lakes impedes rec boating, affects aquatic habitat. Little opportunity for local beneficial use. Lack of cost share to support federal dredging program. Problem: Former USS South Works steel mill site has prime lakefront, but no topsoil. BE Previous workgroup leader, Don Wadleigh, has retired. B. Eleder willing to be workgroup lead. Other GLDT workgroup members are: Steve Pfeiffer, Larry Karnes and Larry Kieck Mike Peloquin has left GLDT (looking for MN replacement for Peloquin and new state co-chair) BE Previous workgroup leader, Don Wadleigh, has retired.

    7. Case Study: Barging Illinois River sediment to Chicago reclamation site Opportunity: River barge access direct from dredge site to beneficial use site. State of Illinois, City of Chicago, and Peoria Lakes region all have an interest in the project.

    8. Case Study: Barging Illinois River sediment to Chicago reclamation site Outcome: Peoria Lakes channels deepened for access to marinas. Transfer and handling of wet sediment proved feasible. Over 100,000 tons of rich Illinois River sediment now supporting growth.

    9. Case Study: Grand Haven sediment used to manufacture marketable topsoil Problem: Dredging backlog reduces cargo throughput, threatens local industry at the port of Grand Haven. Difficulty in locating site for a new confined disposal facility.

    10. Case Study: Grand Haven sediment used to manufacture marketable topsoil Opportunity: Composition and relative non-toxicity of harbor sediment make it a good candidate for beneficial use as topsoil. Plentiful local yard waste available. Corps’ ERDC provides testing of optimum yard waste-sediment mixture. Local dock operator steps up as entrepreneur.

    11. Case Study: Grand Haven sediment used to manufacture marketable topsoil Outcome: Coalition of state, federal and local interests formed. Production begins of marketable topsoil product “Earth Renewed.” Reduction, or elimination of need for new CDF. Resumption of harbor dredging, improved access for commercial marine traffic.
