Stormwater History

Discharges to BWSC's separate storm drainage system are regulated under U.S Environmental Protection Agency's (EPA) National Pollutant Discharge Elimination System (NPDES) Stormwater Permit Regulations. BWSC's NPDES Stormwater Permit (MAS010001) became effective on October 29, 1999.

Under the Permit, BWSC is required to develop and implement stormwater pollution prevention and management programs that are designed to reduce the discharge of pollutants to the municipal storm drainage system to the maximum extent practicable.

In addition, BWSC is required to report annually to the EPA and the Massachusetts Department of Environmental Protection (DEP) regarding the status of its pollution prevention and stormwater management programs. This annual report provides a summary of stormwater management activities undertaken by BWSC, including descriptions of the outfall screening, monitoring and illegal connection remediation programs. Also included are BWSC's annual expenditures for stormwater programs and assessments of structural controls.
