NPDES Phase II

Every year since 2003 all Small Municipal Separate Storm Sewer Systems (MS4) have been required by the Clean Water Act to obtain a permit from the Illinois Environmental Protection Agency (IEPA) for Phase II of the National Pollution Discharge Elimination System (NPDES). Phase I of the NPDES permit was first implemented in 1990 for medium and large municipal separate storm sewer systems.

About Permit

The permit covers discharges from their municipal separate storm sewer systems including storm water runoff, snow melt runoff and surface runoff and drainage. The 2008 permit was extended an additional year, making it a 6 year permit set to expire in 2014.
