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.

The City’s contractor, Archon, has completed 90% of the pipe work, and landscape restoration of disturbed areas is underway.  The pipe work should be 100% completed within the next week.  Soon thereafter, City crews will start to install brand new cables in the pipe.  That work is expected to take 3 to 4 weeks, with the result being a more reliable system for the area.
