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


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

Case StudyBarging 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.

7
Case StudyBarging 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 StudyBarging 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.

Case StudyGrand 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 StudyGrand 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 StudyGrand 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.
