THERMAL DISCHARGES - COOLING WATER INTAKE STRUCTURES

POWER PLANTS THAT ARE AFFECTED

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.
