The City of Chicago, in cooperation with the Illinois Environmental Protection Agency (IEPA), holds an MS4 permit governing stormwater discharges. Historically, MS4 permittees were not required to submit a Notice of Intent (NOI) requesting coverage under IEPA NPDES ILR10 (Storm Water Discharges from Construction Site Activities) for new construction. Effective April 1, 2009, new regulations established by IEPA, mandate that all MS4 communities be required to submit NOIs and post relevant information to the City’s website for public viewing.
