Illinois EPA Updates NPDES General Industrial Permit

Spencer LaBelle and Betsy Powers of SCS Engineers discuss the key updates that multiple industry sectors must now modify in their site-specific Storm Water Pollution Prevention Plans (SWPPP) to comply with the 2023 Illinois Environmental Protection Agency’s (IEPA) General Permit updates effective July 1, 2023. Part D. Paragraph 7.b. of the permit (Duty to Reapply) requires permittees to submit an NOI for renewal no later than 150 days after the new General Permit is issued.

Our authors provide a quick read of the IEPA updated General National Pollutant Discharge Elimination System (NPDES) Permit No. ILR00 for Industrial Storm Water Discharges here in an article published by the Illinois Manufacturer Magazine.
