Indiana Harbor and Canal Dredging and Disposal Project

Welcome to the web site for the Indiana Harbor and Canal Dredging and Disposal Project. This project is designed to dredge and dispose of Indiana Harbor sediment in a way that:

  • Is safe to human health
  • Improves the environment
  • Is economically beneficial

Accurate and timely information is critical to the effective resolution of the many issues associated with the Indiana Harbor Project. This web site has been established to provide you the information you need to stay informed about this effort and related issues. The site will be updated based on the needs of our site visitors. Please let us know what you need and we will attempt to provide it on the site for you.

Project Description:

The existing navigation project consists of a harbor channel ranging in depth from 27 to 29 feet LWD and 2 canals with depths of 22 feet. Due to contaminated sediments and lack of a suitable storage area for the sediment, the harbor has not been dredged since 1972. An estimated dredging backlog of 1.8 million cubic yards of sediments currently causes pollution of Lake Michigan and affects the efficiency of deep draft commercial navigation. The project provides for constructing a confined dredged material disposal facility (CDF) on an USEPA Resource Conservation and Recovery Act (RCRA) site in East Chicago, Indiana. The project will dredge the entire federal channel to congressionally authorized navigation depths, and will include the removal of sediments in adjacent berthing and docking areas at the local sponsors (non-federal) expense. In addition to providing storage for the dredged materials, the CDF will isolate and contain existing on-site soil and groundwater contamination in compliance with the RCRA requirements. The CDF includes the following features:

  • A slurry cutoff wall
  • Outer clay dikes with interior disposal cells
  • Ground water gradient control system
  • A Cut-off wall barrier at the canal
  • A interim wastewater treatment plant
  • Dredging Off-load Facilities
  • Administration Building

Current Status:

Obstruction removal and slurry cutoff wall construction was completed in 2004. Three contracts, Dikes I, II, and III have been completed, the total outer perimeter clay dike as well as the interior dike. Construction of the South Cutoff Wall along the canal and the groundwater gradient control system were completed in the fall of 2009. Additionally, construction was completed in fall 2011 for the installation of an administrative building, garage, and other south end features.  The dredging and CDF operation contract was awarded to a joint venture between Durocher Marine a division of Kokosing Construction Company Inc. and O’Brien & Gere on Sept. 30, 2011. Kokosing Construction Company will perform the dredge work and O’Brien & Gere will operate the CDF which includes site maintenance, operation of the gradient control system, water treatment, and environmental monitoring. The Contractor completed pre-construction submittals and mobilized to the site in spring and summer 2012. Dredging began in the fall of 2012 and, on Aug. 5, 2013, dredging was completed for the calendar year. Dredging will resume in the spring of 2014. The Corps and its contractor will conduct a public meeting for the 2014 dredging year in early spring (exact date of the public meeting will be publicized later.)


The existing Federal navigation project at the Indiana Harbor and Canal was authorized by the River and Harbor Acts of 1910 and subsequent Acts of 1913, 1919, 1922, 1925, 1930, 1932, 1935, 1937, 1960 and 1965; Water Resources Development act of 1986 and 1996; Emergency Supplemental Apportions Act dated 12 May 2005.
