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 Glenview 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. These goals are described in the Notice of Intent.
After each program year, the Village must document its status of compliance with and any changes to the Notice of Intent in an annual Facilities Inspection Report.
How Glenview is addressing all of the above NPDES permit program requirements is outlined in this Stormwater Management Plan.

Learn about environmentally-friendly practices
Green infrastructure uses vegetation, soils and natural processes to manage water and create healthier urban environments. This website is a one-stop shop for resources on green infrastructure that features improved navigability and up-to-date content, including a wealth of publications and tools developed by EPA, state and local governments, the private sector, nonprofit organizations and academic institutions.
Interested in learning more about healthy, environmentally-friendly lawn and landscape practices? You can reduce erosion, stream sedimentation, flooding, runoff of pollutants into local waterways and the risk of pesticide exposure to children, adults, pets and wildlife. The U.S. EPA has produced a series of videos that demonstrate lawn care practices that will reduce pesticide and nutrient risks to human health and the environment. Here's more information.
The Solid Waste Agency of Northern Cook County has produced an Eco-Landscaping Guide to assist homeowners and businesses with alternatives to conventional lawn care methods and chemicals.
