§ 3913. Site-Specific Water Quality Objectives for Copper and Nickel South of the Dumbarton Bridge.
Through Regional Water Board Resolution R2-2002-0061, the San Francisco Bay Regional Water Quality Control Board (Regional Board) amended on May 22, 2002, the Water Quality Control Plan for the San Francisco Bay Region (Basin Plan).
The Basin Plan amendment adopted by the Regional Board includes two new regulatory provisions, which are summarized below.
1. The amendment specifies new site-specific water quality objectives (SSOs) for copper and nickel in the portion of San Francisco Bay South of the Dumbarton Bridge. The SSOs are 6.9mg/1 for a 4-day average and 10.8 for a one-hour average for dissolved copper and 11.9mg/1 for a 4-day average and 62.4mg/1 for a one-hour average for dissolved nickel.
2. The amendment specifies numeric values of metal translators (ration of dissolved to total metal) for copper and nickel in San Francisco Bay South of the Dumbarton Bridge that will be used to compute National Pollutant Discharge Elimination System (NPDES) effluent limitations according to the procedure outlined in the Policy for Implementation of Toxics Standards for Inland Surface Waters, Enclosed Bays, and Estuaries of Californiafor the three Municipal Wastewater Treatment facilities discharging to this portion of San Francisco Bay. These translators are 0.53 for copper and 0.44 for nickel. Other Basin Plan amendments are non-regulatory and consist primarily of language updates and an implementation plan to implement the new site-specific objectives. The implementation plan does not contain any new regulatory requirement (other than establishment of the metal translators described above), but instead summarizes already existing permit requirements.
