1. Restoration Alternatives Development and Evaluation West Branch Grand Calumet River By Dan Sparks, USFWS, BFO Presented by Jim Smith, IDEM, OLQ

20. Scope of Work • Phase 1 - Project Orientation • Task 1. Site Visit • Task 2. Literature and Data Review • Task 3. Data Gaps • Task 4. Local Support • Phase 2 - Fieldwork • Task 5. Work Plans • Task 6. Bathymetric and Topographic Survey • Task 7. Sediment Sampling and Testing

21. Scope of Work • Phase 3 - Analysis and Report • Task 8. Data Analysis and Alternatives Development • No Action • Natural Recovery with Monitoring • Dredging w/ confined aquatic, nearshore, or upland disposal • Dredging w/ dewatering and treatment • Dredging and capping • Capping

22. Scope of Work • Phase 3 - Analysis and Report • Task 9. Restoration Alternatives Report • Introduction • Physical Setting • Sediment Properties • Potential Sediment Remediation Technologies • Screening of Sediment Remediation Technologies • Development of Detailed Restoration Alternatives • Evaluation of Restoration Alternatives • Appendices, etc.

23. Scope of Work • Phase 3 - Analysis and Report • Task 10. Meetings • Site Visit • Public Meetings • Task 11. Project Management • Coordination • Correspondence • Subcontractor’s management, oversight • Billings • etc.

24. Results of Phase I Technical Memorandum Restoration Alternatives Development and Evaluation West Branch Grand Calumet River January 2002

25. Results of Phase I • December 11, 2001 Site Visit • Reviewed Literature and available data • Recommended Project Reaches • Identified 6 Data Gaps

26. Proposed Project Reaches and Past Sample Points Hohman Ave. Calumet Ave. Indianapolis Blvd. Columbia Ave White Oak Ave. ap Railroad Bridge State Line Sohl Road

27. Burton & Dorkin, 1994

28. Data Gap 1Bathymetric / Topographic Survey • Establish Riverbed Topography & Core Sample Elevations • Develop Remedial Alteratives & Establish Dredging / Capping Quantities • Assess Potential Disposal Sites • Evaluate Potential Access to River • Aid in Preparation of Final Restoration Plans

29. Data Gap 2Need Engineering Base Drawings • Historical Sampling Locations • Proposed Sampling Locations • Show Contaminated Sediment Sections • Lay Out Preliminary Dredge / Capping Prisms & Materials • Preliminary Locate & Lay Out Access Sites & Potential Disposal Areas

30. Data Gap 3Transfer Sediment Core Data to Base Drawings • Calculate (X,Y,Z) Sediment Core Data Locations Based on Bathymetric Survey • Place Data on Base Maps

31. Data Gap 4Proposed Additional Core Boring, Sediment Chemical / Physical Properties • Between Indianapolis Blvd & White Oak • Between White Oak & Columbia Ave. • Between Columbia Ave. & Calumet Ave. • Between Calumet Ave & Sohl Road • Between Sohl Road & Hohman Ave. • Between Railroad Bridge & State Line

32. Proposed Sampling

33. Data Gap 5Need Information on Access Sites • Very Shallow Water • Limited Access and Bank Stability for Equipment Insertion, Dewatering, Hauling • Bridges have no Horizontal or Vertical Clearance for Equipment Movement from River Reach to River Reach

34. Data Gap 6Local Sources of Services & Material • Information is needed on: • Local Labor • Dredging Equipment • Construction Equipment • Fleet Vehicles • Aggregate & Sand • Concrete • Related Services

35. What’s Next • Do we Proceed with Phase 2? • Do we do all proposed sampling or reduce number? • Are all parameters identified? • Should we do additional Toxicity Sampling? • Do we obtain New Aerial Photos to develop topographic base maps or can we use some flown in 1994 or 1995?
