* 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.
