Central Valley Natural Gas Storage Project

Background

Central 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.

The Central Valley project, as proposed by the applicant, consists of the operation of a natural gas storage facility that would require the construction of six project components, as follows:

	A 10-acre compressor station and associated facilities
	A 4-acre well pad site containing nine injection/withdrawal wells, one or two saltwater disposal wells, and a 380,000 gallon salt water storage tank
	A 1,400-foot-long, dual 16-inch-diameter gathering line system that connects the injection/withdrawal wells on the remote well pad to the compressor station
	A 300-foot-long, 12-inch-diameter gas pipeline, meter skid, and rental compressor unit for a temporary connection to PG&E Line 172
	A 14.7-mile-long, 24-inch-diameter gas pipeline that connects the compressor station to PG&E Line 400/401
	Conversion of up to four existing wells (Southam #3, Southam #4, Sara Louise #1, and a test well drilled in May 2009); and re-entry of up to two plugged gas wells (Southam #2 and Zumwalt #1-36) to convert to observation wells
	A 1-acre metering station near PG&E Line 400/401.

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 The natural gas would then be withdrawn according to customer demand.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 5.5 billion cubic feet (Bcf) of natural gas in the first year of service (an ultimate working gas capacity of 8 Bcf will be phased in over four years).
