The document summarizes dredging and remediation efforts on the Buffalo River through collaboration between the US Army Corps of Engineers, EPA, NYSDEC, Honeywell, and other stakeholders. Under the Great Lakes Legacy Act and Great Lakes Restoration Initiative, over 625,000 cubic yards of contaminated sediment have been dredged from 2011-2012. Future dredging from 2013-2014 will target remaining risk-based contamination. Long term goals are to contain dredged materials, monitor remedy performance for 10 years, delist beneficial use impairments, and plan beneficial reuse of clean dredged materials for projects like habitat restoration in 5-7 years.

3. Confined Disposal Facility (CDF) #4

4. ~2.1M cubic yard capacity

5. 20 years of O&M dredging

6. Private tipping fees and cost shares for use

8. Initially studied under Corps’ 312 Authority

9. Defined dredge areas and methodologies

10. Potentiallyy Responsible Party (PRP) issues

11. Becomes an unfunded Corps Authority

12. USEPA implemented dredging under GLLA

14. Existing Conditions Report

15. Shoreline Structural Stability Inventory

16. Buffalo River Library – UB and BSC collection of knowledge (2008)

17. Summarization of existing reports and sampling database

18. GIS of historical sampling locations = planning tool

19. USACE/NYSDEC/BNRK phased sampling strategy (> 400 locations)

20. Results of USACE and NYSDEC Sampling

21. Lessened uncertainties associated with contamination depths, contaminant accumulation areas, and volume estimates

22. Provide visualization of “where to dredge”

23. Combined “Operations” & “Toxicology” thought processes

25. Cold Regions Research & Engineering Laboratory

26. Ice Scour Analysis

27. Permitting Process

28. EA/FONSI

29. Expert Technical Support

30. Toxicology, Hydrogeology, & Public Outreach

31. Water quality modeling for dredging material disposal and dredging strategy (minimize cross contamination)

32. Support sediment remedial goal development

33. Four indicator contaminants capture 90%+ of 11

35. Strategic maintenance dredging (below Federal Channel)

36. CDF Improvements by EPA (sediment sequestration)

37. Dredging nearly625,000 cy in 2011 under GLRI

38. Deeper dredging provides future sediment storage

39. Future dredge material will reflect cleaner basin inputs

40. Eventual dredge material disposal to open lake

42. Target risk-based contamination outside of Federal Channel

43. Majority of sediment to CDF – modeling shows long-term containment and no environment al risk; some TSCA

44. Dredging remaining contamination in next two fiscal years

45. Side-of-channel dredging also provides sediment storage for cleaner basin inputs

46. Remedy performance monitoring for 10 years

47. Final Goal: Delisting of most (all?) detrimental BUIsInsert picture or something.

49. Clean Dredged Material will be available in 5-7 years

50. Open Lake Placement as first option (delist BUI)

51. Beneficial use takes 3 – 5 years of planning

52. Opportunities for beneficial use is based upon toxicological risk assessments – “Best Use”

53. Harbor Habitat Restoration (islands) and alike options

54. Sandy dredge material in upper river has wider uses

55. Walk the riparian corridor with key stakeholders
