Ocean Standards - CWA §316(b) Regulation

THERMAL DISCHARGES - COOLING WATER INTAKE STRUCTURES
PERMITTING OF AFFECTED POWER PLANTS

HUMBOLDT BAY POWER PLANT

The Policy is implemented through National Pollutant Discharge Elimination System (NPDES) permits for coastal and estuarine power plants. The applicable Regional Water Boards are responsible for implementing the Policy requirements in NPDES permits for existing coastal and estuarine power plants. The water boards determine requirements to implement best technology available for cooling water intake structures to be included in the permits. State Water Board staff provides technical support to the Regional Water Boards to ensure a high level of statewide consistency in implementing the Policy.

Pacific Gas and Electric Company (PG&E) supports the protection of California’s marine resources through development of a consistent statewide policy implementing Section 316(b). PG&E has clearly demonstrated that support through the repowering of the Humboldt facility without the use of Once-Through Cooling.
