Welcome to the California Public Utilities Commission (CPUC) website for the California Environmental Quality Act (CEQA) review of proposed construction of the Wild Goose Storage, LLC (Wild Goose) Phase 3 Gas Storage Expansion (Phase 3 Expansion). An application for this project was submitted to the CPUC on April 24, 2009 (Application A.09-04-021). The CPUC, through its Environmental Review Team, is conducting an environmental review of the Phase 3 Expansion. This site provides access to public documents and information relevant to the CEQA review process.


Wild Goose has filed an application with the CPUC to construct the Phase 3 Expansion. The CPUC is the CEQA lead agency.

The Wild Goose Gas Storage Project involves past initial development and expansion, and potential future development, of a depleted and formerly abandoned underground natural gas field (the Wild Goose Gas Field, or field). The Wild Goose Gas Storage Project consists of the initial development between April 1997 and April 1999 (the Base Project) and a later expansion (Phase 2 Expansion) of the Wild Goose Gas Storage Facility (Wild Goose Facility). The Base Project was approved by the CPUC through CPCN Decision 97-06-091. Decision 02-07-036 approved the Phase 2 Expansion. To evaluate the Base Project under CEQA, an Initial Study and Mitigated Negative Declaration were prepared in 1997; for the Phase 2 Expansion, the Wild Goose Storage, Inc. Expansion Project Environmental Impact Report (2002 EIR) was prepared; the EIR was certified in 2002.

For the Phase 3 Expansion, Wild Goose is proposing to expand its existing natural gas storage facility beyond the capabilities currently certified to more fully use the injection, withdrawal, and storage capacity of the most suitable natural gas storage reservoirs in the field, resulting in a cumulative total of approximately 650 million cubic feet per day (MMcfd) of injection, 1,200 MMcfd of withdrawal, and 50 billion cubic feet (Bcf) of storage capacity. The Phase 3 Expansion would increase the physical footprint and current operations at the Wild Goose Facility, and would consist of the following four components:

1. Construction, operation, and maintenance of an expansion to the Remote Facility Site (RFS) in Butte County;
2. Reconductoring of up to 6 miles of electrical distribution line east of the RFS, by PG&E, in Butte County;
3. Modifications to the Delevan Interconnect Site in Colusa County; and
4. PG&E’s installation of up to three new hot tapped pipeline connections between the Wild Goose Connection Pipeline and PG&E Lines 400 and 401, near the location of the Delevan Interconnect Site (in Colusa County), to increase permitted storage and operational capacity.

Further information about the Phase 3 Expansion components is presented in the Draft Supplemental Environmental Impact Report.

Wild Goose’s continuing objective for the Wild Goose Facility is to provide highly flexible natural gas storage services to a variety of customers, which includes gas utilities, electric utilities, independent electric generators, gas marketers, gas producers, the core, industrial gas users, and other wholesale and retail gas customers. Working towards this objective will help provide increased gas reliability, the potential for reduced energy price volatility, and the potential for more efficient gas transmission service. The purpose of the Phase 3 Gas Storage Expansion Project is to capture the incremental storage, injection and withdrawal capacity of the natural gas storage facility to meet customer demands into the foreseeable future.

Wild Goose’s proposed date to begin construction is August 2010, and proposed online date is May 2013.
