Stormwater Management

Stormwater and NPDES

Stormwater is water that flows over the ground surface when it rains without being absorbed by vegetation, soil, and other permeable areas. Impervious surfaces like roofs, streets, and sidewalks increase the amount of stormwater that reaches the storm drains. Runoff from roads and lawns can carry pollutants (oil and grease, pesticides, fertilizers, salt, chemicals, etc.) that go untreated, degrading streams and lowering the quality of water. In 1972, the Federal Clean Water Act created the National Pollutant Discharge Elimination System (NPDES) permit program, allowing the U.S. Environmental Protection Agency (EPA) to regulate pollutant discharge from pipes and ditches.

MS4 Permit

The Village of Indian Head Park has a separate storm sewer system (MS4) permit and has filed a Notice of Intent to comply with the permit conditions. This permit requires stormwater pollution to be reduced through six minimum control measures:

  1. Public education and outreach
  2. Public involvement and participation
  3. Illicit Discharge Detection and Elimination - IDDE
  4. Construction site runoff control
  5. Post-construction runoff control
  6. Pollution prevention and good housekeeping

In order to meet these control measures, the Village has created a Stormwater Management Program (SWMP). Additionally, the Village files Annual Reports with the IEPA that describe work completed in the past year.

How You Can Help

Residents and businesses can take steps to help protect Indian Head Park’s waterway, Flagg Creek. To prevent stormwater pollution, avoid dumping anything into storm drains, clean up after your pets, wash vehicles in commercial areas that lead to a sewage treatment plant, install rain gardens, and limit the use of fertilizer and de-icing salt.
