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.

- Braintree Waterbody Assessment & Total Maximum Daily Loads (TMDL) Status Map - This map provides an overview of the impaired waters in Braintree. As defined by Section 303(d) of the Clean Water Act, impaired waters do not meet established state water quality standards. The law requires that states establish priority rankings for impaired waters and develop Total Maximum Daily Loads (TMDLs) for these waters. A TMDL includes a calculation of the maximum amount of a pollutant that can be present in a body of water and still meet quality standards. To learn more about the 303(d) Impaired Waters and TMDL Program, please visit the EPA website.
