California legislation passed in 2022 allows the California Public Utilities Commission to extend Diablo Canyon’s operations to October 31, 2030 if certain conditions are met. To allow continued operation of the power plant, the Water Board must consider two actions: renewing the National Pollutant Discharge Elimination System (NPDES) permit and issuing a Clean Water Act section 401 water quality certification.
