Corps Pursues Alternatives For Chicago Dredged Materials

By Jacob Zdrojewski, Chicago Engineer District

The Chicago Engineer District remains committed to maintaining a safe and fully functioning navigation system within Calumet Harbor and River. As part of this effort, the Corps had previously developed a Dredge Material Management Plan (DMMP) and Environmental Impact Statement, approved in 2020, to support continued dredging operations necessary for maintaining commercial navigation. In 2021, Congress allocated funds to support the vertical expansion of the Dredge Material Disposal Facility, aligning with an operational plan that ensured the containment of dredged material while maximizing opportunities for beneficial reuse.

The state of Illinois recently informed the Corps of Engineers that it opposes the vertical expansion of the facility and will deny any required permits. As a result, the Corps has decided to withdraw the record of decision for the DMMP. The Corps intends to collaborate with the state of Illinois, City of Chicago and the Illinois International Port District to identify whether there are any sustainable, feasible solutions for ensuring continued navigation.

“The Corps remains committed to maintaining commercial navigation in the Calumet Harbor, Calumet River and the Cal-Sag Channel,” said Col. Kenneth Rockwell, commander of the Chicago District. “We will continue to work expeditiously with federal, state and local partners to evaluate potential alternative solutions that ensure navigation remains a viable mode of transportation within the region.”
