Watershed Permits

Mercury and PCBs

A region-wide watershed permit (Order No. R2-2022-0038) addresses municipal and industrial wastewater discharges of mercury and PCBs to San Francisco Bay. It implements the San Francisco Bay Mercury and PCBs TMDLs found in the Basin Plan.

The watershed permit and TMDL are based, in part, on San Francisco Bay discharger mercury data:

• Municipal (POTW) Mercury Data, 2000-2003
• Petroleum Refinery Mercury Data, 2000-2003

Nutrients

A region-wide watershed permit (Order No. R2-2019-0017) addresses municipal wastewater discharges of nutrients to San Francisco Bay.
