Through Regional Water Board Resolution R2-2007-0042, adopted June 13, 2007, the San Francisco Bay Regional Water Quality Control Board amended the Water Quality Control Plan for the San Francisco Bay Region (Basin Plan). On January 15, 2008, the State Water Resources Control Board approved this amendment under State Board Resolution 2008-0005. The Basin Plan amendment includes acute and chronic site-specific dissolved copper water quality objectives in San Francisco Bay (north of the Dumbarton Bridge), numeric metal translators used to calculate water quality-based effluent limits for wastewater discharges to the Bay north of the Dumbarton Bridge, and a Bay-wide implementation strategy to ensure attainment of the copper site-specific water quality objectives.
