Program History

Program Summary

In June 1990, the Program received the first municipal stormwater permit in the nation from the San Francisco Bay Regional Water Quality Control Board (Water Board). In 2001, the Water Board amended the permit to include expanded requirements for controlling pollutants from new and redevelopment activities (Provision C.3). In 2005, the Water Board again amended the permit to allow for phased implementation and to approve key provisions of the Program's Hydromodification Management Plan (HMP). In 2009, new provisions were added requiring trash load reduction from the storm drain system at specified levels by targeted deadlines.

In November 2015, the National Pollutant Discharge Elimination System (NPDES) permit for municipal stormwater discharges in the San Francisco Bay, also known as the Municipal Regional Permit (MRP), was reissued for the 4th time with new requirements. The MRP covers 76 municipal agencies in five Bay area counties and includes requirements for controlling specific pollutants of concern including mercury, polychlorinated biphenyls (PCBs) and trash, water quality monitoring, and implementing stormwater runoff controls for new development and redevelopment projects.

New requirements in the 2015 MRP include development of Green Infrastructure Plans by each member agency, reducing trash loads in stormwater by 80% by July 2019, developing and implementing a trash monitoring program for creeks and shorelines, and reducing mercury and PCB loads to the Bay from stormwater.

As part of the original NPDES permit requirements, the Program produced an Urban Runoff Management Plan. Member agencies continue to submit annual reports to the Water Board. The Program also produces specific reports and work products for various projects. Other program components exist in accordance with NPDES permit guidelines.
