National pollutant discharge elimination system
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 Lake Bluff discharges stormwater from its storm sewer system under Illinois Environmental Protection Agency (IEPA) General National Pollutant Discharge Elimination System Permit No. ILR40 (Permit). 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. These goals are described in the Notice of Intent.
How to reduce pollutants in stormwater runoff
The Village sponsors or participates in a number of programs that help improve water quality by working to eliminate pollutants, such as:
Please call the Village's Stormwater Hotline at 847-234-2153 to report any suspicious discharges to the storm sewer system or a body of water.
