The Connecticut River Stormwater Committee is a coalition working to share information and collaborate on fulfilling obligations under the EPA stormwater permit (known as the General Permit for Stormwater Discharges from the Small Municipal Separate Storm Sewer Systems in Massachusetts or MS4 permit).  The Committee has membership from 19 municipalities and the University of Massachusetts, Amherst, and is facilitated in its work by the Pioneer Valley Planning Commission.  The group’s primary work is to promote education and outreach about stormwater impacts on the Connecticut River.  Their website is an important element of that work. (LinkAlso follow them on Facebook (Link)


Think Blue Massachusetts is an award-winning campaign run by the Massachusetts Statewide Municipal Stormwater Coalition. They are made up of ten regional stormwater groups. They all joined forces in 2016 to help towns and cities meet their stormwater permit requirements. All together they represent 130 communities across the state. Their mission is to help residents and businesses take steps to reduce runoff and keep our state’s lakes, rivers, and streams clean and healthy. (Link)

Why do stormwater discharges from construction activities matter?

When it rains, stormwater washes over the loose soil on a construction site, along with various materials and products being stored outside. As stormwater flows over the site, it can pick up pollutants like sediment, debris, and chemicals from that loose soil and transport them to nearby storm sewer systems or directly into rivers, lakes, or coastal waters. EPA works with construction site operators to make sure they have the proper stormwater controls in place so that construction can proceed in a way that protects your community’s clean water and the surrounding environment.

Who needs to get permit coverage?

In general, the NPDES stormwater program requires permits for discharges from construction activities that disturb one or more acres and discharges from smaller sites that are part of a larger common plan of development or sale. Depending on the location of the construction site, either the state or EPA will administer the permit. See the webpage for Authorization Status for EPA’s Construction and Industrial Stormwater Programs (Link) to find out whether EPA or your state is the permitting authority for construction activities. You can also use the “Do I Need a Permit?” flow chart (Link) to help determine if and from whom you need to get NPDES to permit coverage for your construction activities.
