What is MS4?

MS4 stands for Municipal Separate Storm Sewer Systems. It refers to a system of conveyances (e.g., storm drains, pipes, ditches) owned by a public entity that discharges to U.S. waters and is designed to collect or convey stormwater. It excludes combined sewers and publicly owned treatment works.

The MS4 Program is an unfunded federal mandate requiring municipalities to reduce pollutants in stormwater runoff to improve water quality. Huntington is a Phase II community under this program and must comply with 327 IAC 15-13.

The MS4 is permitted under the National Pollutant Discharge Elimination System (NPDES) through IDEM. Permits are renewed every five years.
