    Dredging
    Section 204
    WRDA 1992 Beneficial Use of Dredged Material

    Restoration Initiative
  • Buffalo River Operations and Maintenance (O&M) Dredging
    • Dredged Material Management Plan (DMMP)
    • Confined Disposal Facility (CDF) #4
    • ~2.1M cubic yard capacity
    • 20 years of O&M dredging
    • Private tipping fees and cost shares for use
    • O&M dredging is commonly biannual event adding up to 150,000 CY per event
  • Buffalo River Environmental
    Dredging Plans
    • First Model: Ashtabula Harbor
    • Initially studied under Corps’ 312 Authority
    • Defined dredge areas and methodologies
    • Potentiallyy Responsible Party (PRP) issues
    • Becomes an unfunded Corps Authority
    • USEPA implemented dredging under GLLA
    • Paved way for collaborative inter-agency goals:
    “Clean up the Buffalo River”
    • Federal solution across Agencies
    “Do not duplicate efforts”
    • Effectively use limited funds
  • Buffalo River Dredging Collaboration
    • USACE 312 Authority
    • Existing Conditions Report
    • Shoreline Structural Stability Inventory
    • Buffalo River Library – UB and BSC collection of knowledge (2008)
    • Summarization of existing reports and sampling database
    • GIS of historical sampling locations = planning tool
    • USACE/NYSDEC/BNRK phased sampling strategy (> 400 locations)
    • Results of USACE and NYSDEC Sampling
    • Lessened uncertainties associated with contamination depths, contaminant accumulation areas, and volume estimates
    • Provide visualization of “where to dredge”
    • Combined “Operations” & “Toxicology” thought processes
    • Defined RISKS from sediment integral to GLLA and GLRI actions
  • Interagency Support - Great Lakes Legacy Act and Great Lakes Restoration Initiative
    • Sediment sampling and analysis support (boats and boots)
    • Cold Regions Research & Engineering Laboratory
    • Ice Scour Analysis
    • Permitting Process
    • EA/FONSI
    • Expert Technical Support
    • Toxicology, Hydrogeology, & Public Outreach
    • Water quality modeling for dredging material disposal and dredging strategy (minimize cross contamination)
    • Support sediment remedial goal development
    • Four indicator contaminants capture 90%+ of 11
    • Intermediary between USEPA/Honeywell and BNRK/NYSDEC teams – GOAL FOCUSED
  • Interagency Support - Great Lakes Legacy Act and Great Lakes Restoration Initiative
    • FY11-12 GLRI Actions - Leverage Corps’ O&M Authority
    • Strategic maintenance dredging (below Federal Channel)
    • CDF Improvements by EPA (sediment sequestration)
    • Dredging nearly625,000 cy in 2011 under GLRI
    • Deeper dredging provides future sediment storage
    • Future dredge material will reflect cleaner basin inputs
    • Eventual dredge material disposal to open lake
    • Delisting of BUIs
  • Interagency Support - Great Lakes Legacy Act and Great Lakes Restoration Initiative
    • FY12-13 GLLA Actions
    • Target risk-based contamination outside of Federal Channel
    • Majority of sediment to CDF – modeling shows long-term containment and no environment al risk; some TSCA
    • Dredging remaining contamination in next two fiscal years
    • Side-of-channel dredging also provides sediment storage for cleaner basin inputs
    • Remedy performance monitoring for 10 years
    • Final Goal: Delisting of most (all?) detrimental BUIs
    Insert picture or something.
  • Buffalo River Section 204 Beneficial Use
    • Post Remedial Dredging activities
    • Clean Dredged Material will be available in 5-7 years
    • Open Lake Placement as first option (delist BUI)
    • Beneficial use takes 3 – 5 years of planning
    • Opportunities for beneficial use is based upon toxicological risk assessments – “Best Use”
    • Harbor Habitat Restoration (islands) and alike options
    • Sandy dredge material in upper river has wider uses
    • Walk the riparian corridor with key stakeholders
