Published June 3, 2019

The U.S. Army Corps of Engineers, Chicago District is extending the public comment period for the draft Chicago Area Waterway System (CAWS) Dredged Material Management Plan (DMMP), and integrated Environmental Impact Statement from 45 to 60 days. The comment period began on May 3, 2019, and the new closing date is July 2, 2019 (changed from the original 45-day closing date of June 17, 2019).  

The purpose of the study is to identify and evaluate alternatives for dredged material management for the CAWS, which is made up of six federal navigation projects: Calumet Harbor and River; the Calumet-Saganashkee (Cal-Sag) Channel; Chicago Harbor; Chicago River; the South Branch of the Chicago River; and the Chicago Sanitary and Ship Canal. The Corps analyzed alternatives that could safely confine 20 years' worth of dredged material generated in the operation and maintenance of the federal navigation channels of the CAWS.
