Welcome to the California Public Utilities Commission (CPUC) website for the California Environmental Quality Act (CEQA) review of proposed construction of the Central Valley Natural Gas Storage Project. An application for this project was submitted to the CPUC on August 19, 2009 (Application A.09-08-008). This site provides access to public documents and information relevant to the CEQA review process. BackgroundCentral Valley Gas Storage, LLC (Central Valley) has filed an application with the CPUC to construct the Central Valley Natural Gas Storage Project located near the unincorporated town of Princeton in Colusa County. The CPUC is the CEQA lead agency. Central Valley proposes to convert, construct, and operate the depleted Princeton Gas Field as a natural gas storage facility. The conversion of the depleted gas field will require the construction of surface and subsurface facilities including a compressor station, remote well pad site, observation wells, metering station, and natural gas connecting pipelines. The project includes construction, operation, and maintenance of the following components:
The project would provide natural gas storage by injecting natural gas into the Princeton Gas Field, a depleted natural gas reservoir located approximately 2,200 feet underground. The natural gas would then be withdrawn according to customer demand. Central Valley proposes to inject into the Princeton Gas Field 9 billion cubic feet (Bcf) of natural gas in the first year of service (an ultimate working gas capacity of 11 Bcf will be phased in over two years). The proposed project would be located in northeastern Colusa County, approximately 60 miles northwest of Sacramento. (See Regional Map). The compressor station and remote well pad site would be located near Princeton, and the PG&E Line 400/401 connecting pipeline would travel west from the compressor station to the metering station, interconnecting with PG&E Line 400/401 several hundred feet south of PG&E’s Delevan compressor station.

On May 5, 2010 the CPUC conducted a public meeting regarding the CVGS Draft MND. The meeting was held at Princeton High School, Multi Purpose Room, Princeton, California. The meeting Agenda, PowerPoint Presentation presented, and Comment Form are available here. The original end of the Draft MND review period was extended from May 22, 2010, to June 7, 2010. Public notice is available here. Comments on the Draft IS/MND were accepted until 5:00 p.m. on June 7, 2010. Please send comments, with the name and address of an appropriate contact person, to:
Commission DecisionThe CPUC voted on October 14, 2010 to approve the proposed project (see Decision D10-10-001) and a Notice of Determination was submitted to the State Clearinghouse. Construction Progress and Mitigation MonitoringReports issued by the CPUC, reports on construction progress, and reports issued as part of the Mitigation Monitoring Program will be published here, when available. For Additional InformationThe CPUC, through its Environmental Review Team, is conducting an environmental review of the project.
