Storm Water Management


What is stormwater?
Stormwater runoff is generated when precipitation from rain and snowmelt events flows over land or impervious surfaces. This runoff can collect pollutants like sediment, oil, grease, and other chemicals as it flows over impervious surfaces in urbanized areas. Polluted stormwater runoff is often transported through Municipal Separate Storm Sewer Systems (MS4s), from which it is frequently discharged untreated into local waterbodies.

What is the Clean Water Act?
The objective of the Federal Water Pollution Control Act, commonly referred to as the Clean Water Act, is to “restore and maintain the chemical, physical, and biological integrity of the nation’s waters.” The National Pollutant Discharge Elimination System (NPDES) program was established to regulate direct discharges into navigable waters. Industrial facilities, construction sites, and cities and communities in urbanized areas must comply with NPDES requirements.

What does the Clean Water Act mean for the Village?
Stormwater discharges from the Village’s MS4 are covered under General NPDES Permit No. ILR40, the General NPDES Permit for Discharges from Small Municipal Separate Storm Sewer Systems.

Storm Water Management Program
The Village of Roscoe has developed a Storm Water Management Program (SWMP) in an effort to reduce the discharge of pollutants from the Village’s MS4 to the maximum extent practicable in order to protect water quality and satisfy water quality requirements of the NPDES Permit No. IRL40 for discharges from Small MS4’s.

Storm Water Pollution Prevention for Construction Sites
Construction sites within the Village are required to comply with regulations for Erosion and Sediment Control contained within the Village of Roscoe Code of Ordinances. However, the NPDES program also regulates stormwater runoff from construction sites. If your construction project disturbs 1 or more acres of land, you may need NPDES permit coverage. The Village inspects construction sites to ensure compliance with permit regulations, as well as compliance with the site’s Stormwater Pollution Prevention Plan (SWPPP). Links are provided below to help you develop your SWPPP, as well as maintain Erosion and Sediment Control Best Management Practices (BMPs) on-site during construction.
