Notice of Staff Data Response & Issue Resolution
Workshop for the
Oakley Generation Station Project
(09-AFC-4)

The California Energy Commission staff will conduct a Data Response and Issue Resolution workshop for the proposed Oakley Generation Station Project (OGS). All interested agencies and members of the public are invited to participate.

The workshop will be held:

FRIDAY, April 23, 2010
Beginning at 10:00 AM

California Energy Commission
First Floor Hearing Room B
1516 9th Street
Sacramento, CA 95814-5512
(Wheelchair Accessible)

Call-in Number (toll free): 1-888-390-0866 (pass code: 25685)

PURPOSE

The purpose of the workshop is to allow staff to provide clarification of staff's data requests, and for the applicant, other parties, interested agencies, and the public, to discuss the, applicant's data responses. The workshop will also focus on resolving project issues and to revise the project schedule. Subjects to be discussed include: Air Quality, Biological Resources, Cultural Resources, Geology, Land Use, Paleontology, Soil & Water Resources, and Transmission System Engineering. Other technical areas may be discussed as necessary.

The status of the proposed project, copies of notices, an electronic version of the AFC, and other relevant documents are also available on the Energy Commission's Internet web site at: http://www.energy.ca.gov/sitingcases/contracosta.

Project Location

The project is located in Oakley, eastern Contra Costa County, California at 6000 Bridgehead Road. The 21.95-acre project site is part of the larger 500-acre DuPont property. The project site is bounded to the west by the PG&E Antioch Terminal, a large natural gas transmission hub, to the north by DuPont property that is either industrial or vacant industrial, to the east by DuPont's titanium dioxide landfill area, and to the south by the Atchison, Topeka and Santa Fe railroad.

Project Description

The Contra Costa Generating Station (CCGS) will be a natural gas-fired, combined-cycle electrical generating facility rated at a nominal generating capacity of 624 megawatts (MW). Principal components of the project include the following:

  • two General Electric (GE) Frame 7FA combustion turbine-generators (CTGs) with a nominal rating of 213 MW each, equipped with metallurgical enhancements to improve efficiency,
  • a single condensing steam turbine generator (STG), heat recovery steam generators (HRSGs), producing a net 218MW,
  • an air-cooled condenser to provide process cooling.

The emission reduction system will include a selective catalytic reduction (SCR) unit to control oxides of nitrogen and an oxidation catalyst to control carbon monoxide and volatile organic compounds in the exhaust gas emissions. Particulate emissions will be controlled by the use of best combustion practices which include the use of low-sulfur natural gas as the sole fuel for the CTGs and auxiliary boiler, and high-efficiency CTG inlet air filtration.

A 2.4-mile-long, single-circuit, 230-kV transmission line will connect the project site with the Pacific Gas and Electric Company (PG&E) Contra Costa Substation. Natural gas will be supplied by a 140 foot long direct connection with the adjacent PG&E Antioch natural gas terminal.

The CCGS proposes to use potable water provided by the Diablo Water District for process and potable uses. Water access is proposed to be through an onsite tap from an existing 27-inch-diameter distribution pipeline that runs through the CCGS site. Process and sanitary wastewater from the CCGS will be discharged to an existing onsite Ironhouse Sanitary District (ISD) sewer line.

Construction of the generating facility, from site preparation and grading to commercial operation is expected to take place from the first quarter of 2011 to the fourth quarter of 2013 (33 months total).
