Municipal Separate Storm Sewer System (MS4) Compliance


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 requir​ed 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 t​hat all MS4 communities be required to submit NOIs and post relevant information to the City’s website for public viewing.

The following is a list of current and completed construction proj​ects in which the CDA has requested/obtained ILR10 coverage. Click a link to view the corresponding NOI, SWPPP, NOC and NOT information.
