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 for which the CDA has requested/obtained ILR10 coverage. Click a link to view the corresponding NOI, SWPPP, NOC, and NOT information.
