San Francisco Bay/Sacramento-San Joaquin Delta Estuary (Bay-Delta) Program

DRAFT REVISED SUBSTITUTE ENVIRONMENTAL DOCUMENT IN SUPPORT OF POTENTIAL CHANGES TO THE WATER QUALITY CONTROL PLAN FOR THE BAY-DELTA: SAN JOAQUIN RIVER FLOWS AND SOUTHERN DELTA WATER QUALITY

On September 15, 2016, the State Water Board released the draft revised Substitute Environmental Document (SED) in support of potential changes to San Joaquin River flow and southern Delta water quality objectives and program of implementation included in the Water Quality Control Plan for the San Francisco Bay/Sacramento-San Joaquin Delta Estuary (Bay-Delta Plan).

Proposed changes to the Bay-Delta Plan include:

  1. New narrative February through June Lower San Joaquin River (LSJR) flow objective applicable to the San Joaquin River and its salmon-bearing tributaries – the Stanislaus, Tuolumne, and Merced rivers – and an associated program of implementation to support and maintain the natural production of viable native LSJR Watershed fish populations migrating through the Delta; and
  2. Revised numeric southern Delta salinity objectives and an associated program of implementation to protect agricultural beneficial uses in the southern Delta.

The SED and associated appendices were prepared in compliance with the California Environmental Quality Act (CEQA), the California Water Code, and other applicable State and federal requirements and include an analysis of the expected environmental, water supply, economic, and hydropower effects of the LSJR flow and southern Delta salinity alternatives.

Written comments were due by noon on Friday, March 17, 2017. The comment period is now closed.

Comments on the proposed Bay-Delta Plan Update and draft SED may be sent to commentletters@waterboards.ca.gov .Please include “Comment Letter – 2016 Bay Delta Plan Amendment & SED” in the subject line.

  • Coming Soon - Comment Letters regarding the draft Bay-Delta Plan Update and draft Revised SED are currently being recorded and processed

After receipt of comments, the State Water Board will make any needed changes to the SED and prepare written responses to comments along with a final draft SED and final draft changes to the Bay-Delta Plan for consideration by the State Water Board. Changes to the Bay-Delta Plan must be approved by the State Water Board and the Office of Administrative Law before becoming effective.
