Municipal Separate Storm Sewer System (MS4)

The MS4 Program addresses the quality of stormwater runoff. The goal of the MS4 Program is to provide a positive water quallity impact in our streams, rivers, and lakes. The MS4 Program is an unfunded mandate by the United States Environmental Protection Agency (EPA) and the Indiana Department of Environmental Management (IDEM) as part of the Phase II National Pollutant Discharge Elimination System (NPDES).

There are two ordinances that pertain to the MS4 Program:

Construction Site & Post Construction Stormwater Control Ordinance #2007-1939.

Illicit Discharge and Connection Stormwater Ordinance #2007-1940.

The Storm Drainage & Sediment Control Ordinance (97-1690) is an ordinance passed by the City of Plymouth Council in April of 1997.
