Construction Site Stormwater Runoff Control

The Illinois Environmental Protection Agency (IEPA) General NPDES Permit No. ILR40 states that any municipality covered by that general permit is also granted automatic coverage under IEPA General NPDES Permit No. ILR10 for the discharge of storm water associated with construction site activities for municipal construction projects disturbing one acre or more. While DuPage County is granted automatic coverage for these construction projects, the County must still comply with the requirements of ILR10, as well as post on its website the Notice of Intent (NOI) documents that have been submitted to IEPA to receive coverage under the ILR10 general permit for each construction project where coverage is required. DuPage County's active construction projects requiring NOI submittals are included below for public informational purposes.
