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 Project. An application for this project was submitted to the CPUC on April 24, 2009 (Application A.09-04-021). 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 Gas Storage Expansion Project. The CPUC is the CEQA lead agency.

The Phase 3 Gas Storage Expansion Project, as proposed by Wild Goose, includes the expansion of the existing Wild Goose Natural Gas Storage Facility (Wild Goose Facility) beyond its currently certificated capabilities to more fully use the injection, withdrawal, and storage capacity of the natural gas storage reservoirs in the Wild Goose Gas Field, located in Butte County, California. The Phase 3 Gas Storage Expansion Project would follow the first development of the gas field (Phase 1 Project), which took place from 1997 to 1999, and a later expansion (Phase 2 Project), which took place starting in 2002. The Phase 3 Gas Storage Expansion Project includes the expansion of the Wild Goose Facility’s Remote Facility Site, modifications to the Delevan Interconnect Site, and installation of a new hot-tap connection to PG&E’s Line 401.

The existing Remote Facility Site would be expanded westward by approximately 540 feet, resulting in an increase in the facility footprint from approximately 12.2 acres to approximately 16.7 acres. The expansion would occupy an area currently used for farm equipment and parking during the hunting season. The westward expansion would also result in the filling and conversion of approximately 4.5 acres of agricultural wetland (rice fields) to industrial use. Four new gas compressor units would be installed as part of the Phase 3 Gas Storage Expansion Project, increasing total compression from approximately 20,700 Horsepower (HP) (six compressor units) to approximately 35,000 HP (10 compressor units). Two new process trains (for a total of five trains) and two new dehydration units and associated equipment would be installed to provide the proposed injection and withdrawal capabilities.

The modifications at the Delevan Interconnect Site would be made entirely within the 0.6-acre facility, and would include the installation of a new PG&E custody transfer meter and associated piping, valves, and instrumentation; and the installation of new piping, valves, and instrumentation for the Wild Goose interconnection pipeline. Wild Goose would also install a new hot-tap connection pipeline, approximately 30 feet in length, from the existing Line 400 Connection Pipeline to PG&E’s Line 401 transmission pipeline, located approximately 700 feet to the west of the Delevan Interconnect Site.

The Phase 3 Gas Storage Expansion Project would be located near the center of the Sacramento Valley, approximately 60 miles northwest of Sacramento in Butte and Colusa Counties (See Figure 1). The Remote Facility Site lies north of West Liberty Road, approximately 1.1 miles west of its intersection with Pennington Road in Butte County. The Remote Facility Site lies within a predominantly agricultural area dedicated mainly to rice production, and is bordered to the north, east, and west by active rice fields. The Gray Lodge Wildlife Area, managed by the California Department of Fish and Game, lies south of the site across West Liberty Road. The Delevan Interconnect Site is located within annual grasslands at the base of the Coast Range foothills, approximately 25 miles west of the Remote Facility Site. The Glenn Colusa Canal lies 0.25 miles east of the Delevan Interconnect Site. Both facilities are located within the relatively flat terrain of the Sacramento Valley floor.

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 April 2010, and proposed online date is April 2012.
