Bay Delta Water Quality Control Plan (Bay Delta Plan)

California State Water Resources Control Board (SWRCB) | December 13th, 2006

"Bay Delta Plan" is short for the State Water Resources Control Board's (State Water Board) San Francisco Bay/Sacramento-San Joaquin Delta Estuary Water Quality Control P

"Bay Delta Plan" is short for the State Water Resources Control Board's (State Water Board) San Francisco Bay/Sacramento-San Joaquin Delta Estuary Water Quality Control Plan. The Bay-Delta Plan identifies the beneficial uses of the Bay-Delta, water quality objectives for the reasonable protection of those beneficial uses, and a program of implementation for achieving the objectives. The Bay-Delta Plan, when implemented, can determine the amount and timing of water entering and moving through the Delta. The State Water Board holds dual responsibilities of allocating surface water rights and protecting water quality. The State Water Board allocates water through an administrative system that is intended to maximize the beneficial uses of water while protecting the public trust, serving the public interest, and preventing the waste and unreasonable use or method of diversion of water. While most water quality control planning is done by the Regional Water Boards, the State Water Board has authority to adopt statewide water quality control plans. The State Water Board adopts the Bay-Delta Plan because of the Delta's importance as a major source of water supply for the state. The Bay-Delta Plan protects water quality in the region and includes water quality objectives to protect fish and wildlife beneficial uses through inflows to the Delta from the Sacramento and San Joaquin rivers and Delta outflows, in addition to objectives for salinity to protect agricultural beneficial uses. The State Water Resources Control Board (State Water Board) is in the process of a phased review and update of the 2006 Water Quality Control Plan for the San Francisco Bay/Sacramento-San Joaquin Delta Estuary (Bay-Delta) (referred to as the 2006 Bay-Delta Plan). To learn more about the Bay-Delta Plan, click here. In 2009, the State Water Board began the process of reviewing and likely revising the 2006 Bay Delta Plan.  At the time of the archiving of this document, that update process still continues.  For the latest information, click here to visit the State Water Resources Control Board page for the Bay-Delta Plan Update.. RELATED DOCUMENT: Water Rights Decision 1641, the document that implements the 1995 Bay Delta Plan and is still in force.

Biological opinion on the coordinated operations of the Central Valley Project (CVP) and State Water Project (SWP)

U.S. Fish and Wildlife Service (FWS) | December 15th, 2008

On May 16, 2008, the U.S. Bureau of Reclamation and the California Department of Water Resources asked the Service to initiate consultation on the Long-Term Operational Criteria and Plan (OCAP) for coordination of the Central Valley Project and State Water Project, specifically concerning the delta smelt and its critical habitat. (See OCAP Legal Archives.) On December 15, 2008, the Fish & Wildlife Service issued a biological opinion (BO) on the Long-Term Operational Criteria and Plan (OCAP) for coordination of the Central Valley Project and State Water Project. The Service determined that the continued operation of these two water projects, as described in the plan, was likely to jeopardize the continued existence of the delta smelt and adversely modify its critical habitat. The inclusion by the Service of reasonable and prudent alternatives, and their acceptance by the water agencies, avoided jeopardy and adverse modification.

Brackish Water Desalination Facility Draft Environmental Impact Report

The City proposes to construct, operate, and maintain the Antioch Brackish Water Desalination Project (proposed project). The City proposes to replace the existing San Joaquin River intake pump station, construct a desalination facility with associated equipment and appurtenances; and construction of pipelines for the conveyance of source water and brine concentrate. The desalination plant would have the capacity to produce up to 6 million gallons per day (mgd) of desalinated product water to offset use of purchased water. Due to size, this file has been divided into two parts. Part 1, Part 2

Brackish Water Desalination Facility Project

The City of Antioch (City) is proposing the Brackish Water Desalination Project (Project), which consists of the construction of a desalination facility at the City’s water treatment plant (WTP) with the capacity to produce up to 6 million gallons per day (mgd) of finished water; demolition of the existing San Joaquin River intake pump station; construction of a new intake pump station; approximately 3,000 feet of pipeline from the existing raw water pipeline underneath Lone Tree Way to the City’s WTP to allow a direct connection to maximize use of existing infrastructure; and approximately 4 miles of pipeline from the desalination facility to the Delta Diablo wastewater treatment plant (WWTP) to discharge brine with the WWTP effluent through the existing Delta Diablo outfall to New York Slough. The Project facilities would be located in the cities of Antioch and Pittsburg, California (Figure 1), at the western edge of the San Joaquin- Sacramento Delta (Delta). The main objectives of the Project are to improve water supply reliability and water quality for its customers; develop a reliable and drought-resistance water source to reduce dependency on purchased water supplies; maximize and preserve the use of the City’s pre-1914 water rights; and provide cost effective operational flexibility for the City.
