Municipal Separate Storm Sewer System (MS4) Program Documents

EPA MS4 Stormwater Program

The storm drain system in Braintree is regulated by the Environmental Protection Agency MS4 (Municipal Separate Storm Sewer System) permit program. The issuance of this permit means that residents, businesses, developers, and industrial facilities in Braintree shall only discharge clean stormwater. The Braintree Stormwater Division is responsible for ensuring that nothing enters the system that can pollute our streams, rivers, and lakes.
