Bloomingdale Township NPDES

National Pollution Elimination System is a permit program to control water pollution by regulating point sources that discharge pollutants into waters of the United States.

Polluted stormwater runoff is commonly transported through Municipal Separate Storm Sewer Systems (MS4s) and then often discharged, untreated, into local water bodies.  An MS4 is a conveyance or system of conveyances that is/are:

-          Owned by a state, city, town, village or other public entity that discharges to waters of the US

-          Designed or used to collect or convey storm water (e.g. storm drains, pipes, ditches)

-          Not a combined sewer; and

-          Not part of a sewage treatment plant, or publicly-owned treatment works

To prevent harmful pollutants from being washed or dumped into specific types of MS4s, operators are required to obtain an NPDES permit and develop a Stormwater Management Program Plan (SMPP).  Bloomingdale Township is a MS4 operator under the IEPA’s General Permit for discharge.
