The City of Dublin's stormwater program is a mandated program under the federal Clean Water Act which is codified in Dublin Municipal Code Chapter 7.74, Stormwater Management and Discharge Control. The City, along with 75 other municipalities and agencies in the Bay Area, is a co-permittee under the Municipal Regional Stormwater NPDES Permit which is administered by the San Francisco Bay Regional Water Quality Control Board. The purpose of the stormwater program is to eliminate pollutants, such as motor oil, dirt, pesticides, litter, pet waste, and other contaminants from entering the storm drain system. Pollutants such as these flow from yards, parking lots, and streets sending contaminated water, also known as urban runoff, untreated into local creeks, groundwater, and ultimately San Francisco Bay, where it harms fish and other wildlife. It is estimated that 50% to 80% of all pollutants entering the San Francisco Bay are discharged from storm drain systems. Remember: Only Rain Down the Storm Drain!
