Village of Winnetka
Water pollution degrades surface waters, making them unsafe for drinking, fishing, swimming and other activities.
As authorized by the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) permit program controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Point sources are discrete conveyances such as pipes or man-made ditches.
Since its introduction in 1972, the NPDES permit program is responsible for significant improvements to our nation's water quality. Individual homes that are connected to a municipal system, use a septic system or do not have a surface discharge do not need an NPDES permit; however, industrial, municipal and other facilities must obtain permits if their discharges go directly to surface waters.
The Village of Winnetka discharges stormwater from its storm sewer system under IEPA General National Pollutant Discharge Elimination System Permit No. ILR40.
As a condition of the permit, the Village is required to set goals for a five-year period in order to reduce pollution to the receiving waters. The goals are described in the Notice of Intent.
After each program year, the Village must document its status of compliance with and any charges to the Notice of Intent in an Annual Facility Inspection Report.
The Village of Winnetka sponsors or participates in a number of programs that help improve water quality by working to eliminate pollutants:
