The U.S. Army Corps of Engineers, Chicago District, has established the Lake Michigan Regional General Permit (LMRGP) for activities located within Lake Michigan in Cook and Lake Counties, Illinois, effective October 1, 2020. The LMRGP authorizes a group of activities which would have minimal individual and cumulative impacts on aquatic resources.
