5. 1975 – The First Basin Plan Water Quality Standards Resolution 68-16 = antidegradation Beneficial uses Water quality objectives No toxics in toxics amounts

6. 1975 – The First Basin Plan Prohibitions (no < 10 to 1 dilution) Secondary treatment for wastewater Future attempts to control water quality must be based on factors more omnibus than consideration of municipal and industrial wastewater treatment alone.

7. 1982 – Basin Plan Toxicity limit in wastewater permits Metals and CN limits Construction-site erosion and sediment control

8. 1986 – Basin Plan Metals water quality objectives Metals and CN limits Flow-through bioassay acute toxicity limit Chronic toxicity studies Urban runoff management Program

9. Inception of Regional Monitoring RMP created in 1992 Based on UC Santa Cruz and BPTC Program studies Other factors SF Estuary Project SF Estuary Institute

10. 1995 – 2005 Basin Plans Narrative no bioaccumulation objective NPDES stormwater regs Dredging and dredge disposal Long Term Management Strategy California Toxics Rule and State Implementation Policy
