Management Approach Toxic Pollutant Management in the Larger San Francisco Bay Estuary System Numerical Water Quality Objectives: Wasteload Allocations Toxic Pollutant Accumulation: Mass-Based Strategies Scientific Research: Ongoing Refinement of Programs Riverine Flows, System Flushing, and Pollutant Loading Delta Outflow San Luis Drain Toxic Pollutant Management in Segments of the San Francisco Bay Estuary Local Wasteload Allocation Effluent Toxicity Control Program: Local Toxicity Objectives Local Toxic Pollutant Accumulation Toxic Pollutant Management in Individual Watersheds The Napa Example The Corte Madera Creek Example Discharge Prohibitions Applicable Throughout the Region Surface Water Protection and Management—Point Source Control Types of Point Sources Waste Discharge
