The Environmental Quality Department shares responsibility for stormwater management with the Public Works Department, Building and Zoning Department, and Village Engineer. The Village must maintain compliance with stormwater programs as outlined by the Lake County Stormwater Management Commission and the Illinois Environmental Protection Agency.
National Pollutant Discharge Elimination System (NPDES) Phase II
In 2003, the Illinois Environmental Protection Agency (IEPA) began issuing to small municipalities, an NPDES General Storm Water Permit for discharges from the separate storm sewer system. The current permit became effective March 1, 2016 and expires on February 28, 2021. As part of the permit renewal process, the Village submits a Notice of Intent (NOI) (PDF) as well as annual reports to the IEPA.

Stormwater runoff occurs when precipitation from rain or snowmelt flows over the ground. Impervious surfaces like driveways, sidewalks, and streets prevent stormwater from naturally soaking into the ground. Polluted stormwater runoff is a leading cause of impairment to the nearly 40% of surveyed U.S. water bodies which do not meet water quality standards. Over land or via storm sewer systems, polluted runoff is discharged, often untreated, directly into local water bodies. When left uncontrolled, this water pollution can result in the destruction of fish, wildlife, and aquatic life habitats; a loss in aesthetic value; and threats to public health due to contaminated food, drinking water supplies, and recreational waterways.
Report Hazardous Materials Discharge
Should you witness the discharge of hazardous materials to the Village’s storm sewer system or its plentiful waterways please do not confront the individual yourself. Please call either the Department of Public Works at 847-526-9610 or RHMG Engineers, Inc. at 847-362-5959 to report an illicit discharge.
