Municipal Separate Stormwater Sewer System (MS4) Program

Stormwater is water from a precipitation event that does not soak into the ground and runs across impervious surfaces, such as roofs and driveways, and picks up pollutants including oil, sand, fertilizer, pet waste and salt. The stormwater then enters the storm sewer system and is eventually discharged into our local lakes and rivers, taking the pollutants with it.

Because of the harm that stormwater runoff pollution can have on local waterbodies the NYS Department of Environmental Conservation (DEC) developed a regulatory program, The MS4 program, to help larger municipalities decrease the amount of pollution in stormwater. An MS4 (Municipal Separate Storm Sewer System) is a conveyance system (such as roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels or storm drains) that is designed for collecting or conveying stormwater, not a combined sewer and not part of a publicly owned treatment system.

There are eight "Small Regulated MS4" communities in the Lake Champlain - Lake George area: City of Glens Falls, Town of Queensbury, Town of Fort Edward, Village of Fort Edward, Town of Kingsbury, Village of Hudson Falls, Warren County DPW and Washington County DPW. As "Regulated Small MS4s", the communities have to implement Phase II Stormwater Regulations by January 2008. This includes implementing their individual Stormwater Management Programs.

A Stormwater Management Program (SWMP) is a program each MS4 community has to implement to improve the quality and quantity of stormwater discharging from their community. There are six Minimum Control Measures (MCMs) that the MS4 community has to address in their individual SWMP. These include:

The LCLGRPB continues to assist each MS4 community individually and collectively with public education, public outreach, illicit discharge and infrastructure mapping and municipal operations. This also involves obtaining funding and administrating grants to continue their long term stormwater programs.
