NOTICE: State Water Board rescinds notice on Bay Delta Plan Sacramento/Delta update; workshops to be rescheduled

Notice from the State Water Board:

This message is to notify interested parties that the State Water Resources Control Board (State Water Board or Board) has rescinded the August 22, 2025 Second Revised Notice of Opportunity for Public Comment and Hearing on Revised Draft Sacramento/Delta Updates to the Water Quality Control Plan for the San Francisco Bay/Sacramento-San Joaquin Delta Watershed (Bay-Delta Plan or Plan). The Rescinded Notice is available on the Board’s website. Accordingly, the hearing previously scheduled for September 24-25, 2025, and the associated public comment period are cancelled and will be rescheduled to a future date.

Updating the Sacramento/Delta components of the Bay-Delta Plan is one of the State Water Board’s top priorities, and the Board is working expeditiously to complete this update. Board staff anticipate a limited recirculation of the draft Staff Report/Substitute Environmental Document in support of the Sacramento/Delta updates to the Bay-Delta Plan together with the updated draft Plan in December 2025. New dates for a public hearing and comment period will be announced upon release.

The August 22, 2025 supplemental model results remain available for public review, but the Board is not soliciting comments on the supplemental model results at this time.
