Municipal Regional NPDES Permit
NPDES Permit
In June 1990, the Program received the first NPDES municipal stormwater permit in the nation from the San Francisco Bay Regional Water Quality Control Board (Water Board). The permit was reissued in 1995, 2001 and 2009 and 2015. The permit reissued in 2009 and 2015 is referred to the Municipal Regional Stormwater NPDES Permit (MRP). The MRP covers stormwater discharges from a total of 76 municipalities and local agencies in Alameda, Contra Costa, San Mateo and Santa Clara Counties, and the cities of Fairfield, Suisun City, and Vallejo. Challenging stormwater management requirements in the current MRP include:
- Reducing trash loads from stormwater by 100% by July 2022
- Developing and implementing a trash monitoring program for creeks and shorelines
- Meeting mercury and PCBs stormwater reduction goals
- Developing and implementing Green Stormwater Infrastructure (GSI) Plans

Stormwater Pollution Prevention Authority
The West Valley Clean Water Program Authority (Authority) serves as the Stormwater Pollution Prevention Authority for the cities of Campbell, Monte Sereno, Saratoga and the Town of Los Gatos. The Authority was created to maximize the effectiveness, efficiency, and cost benefit from collective stormwater pollution prevention efforts of the four West Valley communities. The Authority was formally established in February 2018 but has been operating as a collaborative stormwater management program since 1992.
The Authority’s member agencies must comply with the NPDES stormwater permit, which mandates certain activities including maintenance of the stormwater drain system. The Authority develops an annual work plan to fulfill the requirements of its MRP and to reduce the amount of pollutants discharged in urban runoff. The plan is a comprehensive program that is designed to reduce the discharge of pollutants to the maximum extent practicable and encompasses best practices for the following operational areas:
- C.2. Municipal Operations
- C.3. New Development & Redevelopment
- C.4. Industrial & Commercial Site Controls
- C.5. Illicit Discharge Detection & Elimination (IDDE)
- C.6. Construction Site Controls
- C.7. Public Information & Outreach
- C.8. Water Quality Monitoring
- C.9. Pesticides Toxicity Controls
- C.10. Trash Load Reductions
- C.11. Mercury Controls
- C.12. Polychlorinated Biphenyls (PCBs) Controls
- C.13. Copper Controls
-
C.2 Municipal Operations
Permittees are required to implement appropriate Best Management Practices (BMPs) to control and reduce non-stormwater and polluted stormwater discharges to storm drains and watercourses during operation, inspection, and routine repair and maintenance activities of municipal facilities and infrastructure.
