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

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 3 Transfer 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 4 Proposed 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
Whats 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?
