The Highway Department manages the Town’s storm drainage system, also known as a Municipal Separate Storm Sewer System (MS4). The Town is authorized to discharge stormwater through the Phase II National Pollutant Discharge Elimination System (NPDES) General Permit for Stormwater Discharges from Small MS4s in Massachusetts. The U.S. Environmental Protection Agency (EPA) oversees the NPDES program. Each Community with an MS4 in designated urbanized areas must develop a Stormwater Management Program (SWMP) that will guide its activities under the 2016 MS4 general permit. These documents are available for review by clicking on the links above. Questions and comments on the plan can be made through the "MS4 Questions or Comments?" form on this page to the right.
