A Water Quality Basin Plan prepared for the region in 1986 by the Regional Water Quality Control Board (RWQCB) promulgated regulations to control inputs of pollutants to South San Francisco Bay from both point and nonpoint sources. Although point sources from wastewater treatment plants and industrial process water discharge had previously been regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, discharges of stormwater from diffuse, or nonpoint, sources were not controlled. The San Francisco Bay RWQCB decided that the South Bay municipalities must obtain a permit for their stormwater discharges. Consequently, the Santa Clara Valley Water District, Santa Clara County, and thirteen cities within the County commissioned a study of stormwater runoff from municipalities in the Valley and to develop control measures to decrease pollutants in stormwater runoff. Data collected as part of this study was then submitted as support material for one of the first stormwater discharge permits issued in the U.S. under the NPDES permit system.
