What is the MS4 storm water program?
Untreated or uncontrolled storm water runoff is the number one cause of impairment to our local waterways.
Pollute runoff is often transported through municipal storm water systems where it is eventually discharged into streams untreated. The Environmental Protection Agency (EPA) has established a municipal storm water management program known as the MS4 Program that is intended to improve our Nations's waters by reducing the quantities of pollutants that storm water picks up and carries into the storm water systems during a storm event.
Check the EPA's website for further information on the MP4 Program.
