The City of Chicago, in cooperation with the Illinois Environmental Protection Agency (IEPA), holds a MS4 permit governing storm water 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.
The following is a list of new/ongoing construction projects in which the CDA has requested/obtained ILR10 coverage. Click a link to view the corresponding NOI, SWPPP, and NOT information.
