Municipal Separate Storm Sewer System (MS4)

MS4 Programs in New York

The Municipal Separate Storm Sewer System (MS4) program is an important initiative designed to protect water quality and manage stormwater runoff in urban areas across New York State. Under the MS4 regulations, municipalities are required to develop and implement a stormwater management program that aims to reduce the discharge of pollutants into local waterways. This program addresses various aspects of stormwater management, including public education, good housekeeping practices for municipal operations, and the regulation of construction site runoff.

In New York, the MS4 program mandates that municipalities create a Stormwater Management Plan (SWMP) that outlines specific goals and practices tailored to their local needs. This includes strategies for controlling non-point source pollution, managing post-construction stormwater, and enhancing the overall health of water bodies within the community. By promoting practices such as the installation of green infrastructure, proper maintenance of drainage systems, and community engagement, MS4 programs play a crucial role in safeguarding water resources and fostering sustainable urban environments. These efforts not only benefit the ecosystem but also contribute to the quality of life for residents by reducing flooding and improving overall water quality.
