Creating A Paradigm Shift, Putting the Buffalo River First: Usace

  1. 1. GLRI <br />$<br />Buffalo River Dredging Success USACE Authorities<br />Collaboration: <br />BNRKPR<br />USEPA – GLNPO *<br />Region 2<br />NYSDEC<br />Honeywell<br />NYSAG<br />USFWS<br />Stakeholders<br />Operations and Maintenance (O&M)<br /> Dredging<br />Section 204 <br />WRDA 1992 Beneficial Use of Dredged Material<br />Section 312 <br />WRDA 1990 Environmental Dredging<br />Interagency Support<br /> Great Lakes Legacy Act<br />Great Lakes<br />Restoration Initiative<br />
  2. 2. Buffalo River Operations and Maintenance (O&M) Dredging<br /><ul><li> Dredged Material Management Plan (DMMP)
  3. 3. Confined Disposal Facility (CDF) #4
  4. 4. ~2.1M cubic yard capacity
  5. 5. 20 years of O&M dredging
  6. 6. Private tipping fees and cost shares for use
  7. 7. O&M dredging is commonly biannual event adding up to 150,000 CY per event</li></li></ul><li>Buffalo River Environmental<br />Dredging Plans <br /><ul><li>First Model: Ashtabula Harbor
  8. 8. Initially studied under Corps’ 312 Authority
  9. 9. Defined dredge areas and methodologies
  10. 10. Potentiallyy Responsible Party (PRP) issues
  11. 11. Becomes an unfunded Corps Authority
  12. 12. USEPA implemented dredging under GLLA
  13. 13. Paved way for collaborative inter-agency goals:</li></ul>“Clean up the Buffalo River”<br /><ul><li>Federal solution across Agencies</li></ul>“Do not duplicate efforts”<br /><ul><li>Effectively use limited funds</li></li></ul><li>Buffalo River Dredging Collaboration<br /><ul><li>USACE 312 Authority
  14. 14. Existing Conditions Report
  15. 15. Shoreline Structural Stability Inventory
  16. 16. Buffalo River Library – UB and BSC collection of knowledge (2008)
  17. 17. Summarization of existing reports and sampling database
  18. 18. GIS of historical sampling locations = planning tool
  19. 19. USACE/NYSDEC/BNRK phased sampling strategy (> 400 locations)
  20. 20. Results of USACE and NYSDEC Sampling
  21. 21. Lessened uncertainties associated with contamination depths, contaminant accumulation areas, and volume estimates
  22. 22. Provide visualization of “where to dredge”
  23. 23. Combined “Operations” & “Toxicology” thought processes
  24. 24. Defined RISKS from sediment integral to GLLA and GLRI actions</li></li></ul><li>Interagency Support - Great Lakes Legacy Act and Great Lakes Restoration Initiative<br /><ul><li>Sediment sampling and analysis support (boats and boots)
  25. 25. Cold Regions Research & Engineering Laboratory
  26. 26. Ice Scour Analysis
  27. 27. Permitting Process
  28. 28. EA/FONSI
  29. 29. Expert Technical Support
  30. 30. Toxicology, Hydrogeology, & Public Outreach
  31. 31. Water quality modeling for dredging material disposal and dredging strategy (minimize cross contamination)
  32. 32. Support sediment remedial goal development
  33. 33. Four indicator contaminants capture 90%+ of 11
  34. 34. Intermediary between USEPA/Honeywell and BNRK/NYSDEC teams – GOAL FOCUSED</li></li></ul><li>Interagency Support - Great Lakes Legacy Act and Great Lakes Restoration Initiative<br /><ul><li> FY11-12 GLRI Actions - Leverage Corps’ O&M Authority
  35. 35. Strategic maintenance dredging (below Federal Channel)
  36. 36. CDF Improvements by EPA (sediment sequestration)
  37. 37. Dredging nearly625,000 cy in 2011 under GLRI
  38. 38. Deeper dredging provides future sediment storage
  39. 39. Future dredge material will reflect cleaner basin inputs
  40. 40. Eventual dredge material disposal to open lake
  41. 41. Delisting of BUIs</li></li></ul><li>Interagency Support - Great Lakes Legacy Act and Great Lakes Restoration Initiative<br /><ul><li> FY12-13 GLLA Actions
  42. 42. Target risk-based contamination outside of Federal Channel
  43. 43. Majority of sediment to CDF – modeling shows long-term containment and no environment al risk; some TSCA
  44. 44. Dredging remaining contamination in next two fiscal years
  45. 45. Side-of-channel dredging also provides sediment storage for cleaner basin inputs
  46. 46. Remedy performance monitoring for 10 years
  47. 47. Final Goal: Delisting of most (all?) detrimental BUIs</li></ul>Insert picture or something.<br />
  48. 48. Buffalo River Section 204 Beneficial Use<br /><ul><li> Post Remedial Dredging activities
  49. 49. Clean Dredged Material will be available in 5-7 years
  50. 50. Open Lake Placement as first option (delist BUI)
  51. 51. Beneficial use takes 3 – 5 years of planning
  52. 52. Opportunities for beneficial use is based upon toxicological risk assessments – “Best Use”
  53. 53. Harbor Habitat Restoration (islands) and alike options
  54. 54. Sandy dredge material in upper river has wider uses
  55. 55. Walk the riparian corridor with key stakeholders</li>
