Section 3919.1 - Site-Specific Water Quality Objectives for Cyanide for San Francisco Bay and an Implementation Plan

Through Regional Water Board Resolution R2-2006-0086, adopted December 13, 2006, the San Francisco Bay Regional Water Quality Control Board amended the Water Quality Control Plan for the San Francisco Bay Region (Basin Plan). On December 4, 2007, the State Water Resources Control Board (State Water Board) approved this amendment under State Water Board Resolution No. 2007-0077. The Basin Plan amendment includes new regulatory provisions, summarized below:

* Chronic (4-day average) and acute (1-hour average) marine site-specific objectives for cyanide in San Francisco Bay.

* An implementation plan and monitoring surveillance program to ensure maintenance and attainment of the marine site-specific objectives and protection of water quality.

* Effluent limits for cyanide shall be derived from the new marine site-specific objectives, using the methodology in the "Policy for Implementation of Toxics Standards for Inland Surface Waters, Enclosed Bays, and Estuaries of California."

* Where a shallow water discharge is allowed, effluent limits for such discharges will be based on the dilution credits set forth in the amendment.
