Regulated Navigation Area, Chicago Sanitary and Ship Canal, Romeoville, IL

The Coast Guard proposes to amend the navigational and operational restrictions of the Regulated Navigation Area (RNA) on the Chicago Sanitary and Ship Canal (CSSC) near Romeoville, Illinois and remove the redundant Safety Zone currently in place. The purpose of this amendment is to improve safety and clarify regulations for vessels transiting the navigable waters located adjacent to and over the U.S. Army Corps of Engineers' Aquatic Nuisance Species electric dispersal barrier system (EDBS).
