Central Coast Regional Water Board Hearing

The Central Coast Regional Water Board will hold a hearing on a new National Pollutant Discharge Elimination System (NPDES) permit and Clear Water Act 401 Certification associated with the October 31, 2030 extended operations of the Diablo Canyon Power Plant.

The Central Coast Water Board regulates waste discharges from the power plant via the NPDES permit.  These waste discharges include cooling water, treated process water, desalination brine, stormwater, and treated domestic wastewater discharged into Diablo Cove.

Before the Nuclear Regulatory Commission's license renewals can be considered for approval, the Central Coast Water Board must certify that discharges to ocean waters resulting from the license renewals will comply with California's water quality standards.  Among other things, the Clean Water Act section 401 water quality certification will rely on the NPDES permit requirements, which include effluent limitations to control the waste discharges described above, to confirm water quality standard compliance.

Date: February 26 and 27, 2026
