In response to the federal Clean Water Act, all municipalities are regulated waste dischargers under a National Pollutant Discharge Elimination System (NPDES) Permit administered by the appropriate Regional Water Quality Control Board.
Accordingly, the municipalities are regulated with regard to their jurisdiction over and/or maintenance responsibility for municipal storm drain systems and watercourses that they own or operate. The NPDES Permit is concerned primarily with regulating trash, pollutants of concern and excessive hydrologic runoff which can carry sediment and cause flooding.
Bay Area Stormwater Programs worked with The San Francisco Bay Regional Water Quality Control Board to draft a ground-breaking Bay Area wide Municipal Regional Permit (MRP) that encompasses the permittees of Alameda, Contra Costa, Santa Clara, San Mateo counties, and permittees of the cities of Fairfield – Suisun, and Vallejo. The MRP “levels the playing field” and subjects all permittees to virtually the same requirements, allowing some room for flexibility.
