Stormwater Management & Pollutant Discharge Reduction

The City of St. Charles holds a General National Pollutant Discharge Elimination System Permit from the Illinois EPA for stormwater discharges from its municipal separate storm sewer system (MS4).  To protect water quality, the MS4 Permit requires that the City develop and implement a stormwater management program designed to reduce the discharge of pollutants from its stormwater system to the maximum extent practicable. Links are provided below to the City’s MS4 Stormwater Management Plan, Notice of Intent to comply with the MS4 Permit, and annual reports.

To report water quality issues within the City, contact the Public Works Department at 630-377-4405.

Additional MS4 Permit program information can be found at Illinois EPA’s MS4 webpage: https://www2.illinois.gov/epa/topics/forms/water-permits/storm-water/Pag...
