There is no Hampshire County government, so stormwater is regulated town by town. Northampton, Amherst, and Easthampton are EPA-regulated MS4 communities, and each town's Conservation Commission reviews work near the Connecticut and Mill Rivers under the state Wetlands Protection Act.
Massachusetts abolished Hampshire County government in 1999, so stormwater is controlled town by town, backed by state and federal law. Northampton, Amherst, and Easthampton hold EPA NPDES MS4 permits and enforce local stormwater bylaws that meet the Massachusetts Stormwater Standards administered by MassDEP. New development and added impervious area must manage runoff on site through detention, infiltration, and low-impact design. Where work sits within 100 feet of a wetland or the 200-foot Riverfront Area along the Connecticut or Mill Rivers, the town Conservation Commission reviews it under the Wetlands Protection Act (MGL c.131 §40) through a Notice of Intent and Order of Conditions.
Building without an approved stormwater plan draws stop-work orders and municipal fines, and an illicit discharge to a storm drain or wetland triggers MassDEP and Conservation Commission enforcement, with penalties and required restoration.
