NOTICE OF RECEIPT
PG&E PETITION TO ELIMINATE THE USE OF SAN JOAQUIN RIVER
WATER AS THE COOLING WATER SOURCE AND COMPLETE TEN
ASSOCIATED PROJECT DESIGN CHANGES AT THE
GATEWAY GENERATING STATION (00-AFC-1C)

On December 19, 2006, Pacific Gas and Electric Company (PG&E) filed a petition with the California Energy Commission requesting to amend the Energy Commission Decision to eliminate the use of San Joaquin River water as the cooling water source for the Gateway Generating Station Project (formerly known as the Gateway Power Plant Unit 8 Project). The petition also proposes ten associated project design changes at the project. The 530-megawatt project was certified by the Energy Commission on May 30, 2001. Construction of the facility started late in 2001 and was suspended in February of 2002 due to financial difficulties, with approximately 7 percent of construction completed. On July 19, 2006, the Energy Commission approved the addition of PG&E as co-owner of the project with Mirant Delta, LLC. On December 4, 2006, PG&E filed a petition to remove Mirant as a co-owner and change the name of the facility to the Gateway Generating Station. The facility is located north of the City of Antioch, in Gateway County.

DESCRIPTION OF PROPOSED MODIFICATION

PG&E has proposed eliminating the use of San Joaquin River water as the cooling water source for the project and has proposed completing the following ten associated project design changes at the facility in support of this change in cooling technology:

  • Replace the wet cooling tower and surface condenser with an air cooled condenser (ACC)
  • Replace the water treatment building with a trailer mounted water treatment system and relocate the system to the south side of the project site
  • Revise the discharge source for the oil/water separator
  • Incorporate a condensate polishing system associated with the ACC
  • Eliminate the use of steam power augmentation
  • Replace the combustion turbine inlet evaporative cooling system with inlet chilling systems for each combustion turbine
  • Incorporate two electric firewater pumps
  • Incorporate a 500,000 gallon fire water storage tank
  • Incorporate a new fire water tank fill line and potable water supply pipeline
  • Incorporate a new wastewater/sewer pipeline

ENERGY COMMISSION REVIEW PROCEDURES

Code of Regulations, section 1769). Energy Commission staff is currently analyzing the request and will publish a staff analysis. A public hearing for the purpose of approving or denying the amendment proposal will be held at a regularly scheduled Energy Commission business meeting.

The petition is available on the Energy Commission's website at www.energy.ca.gov/sitingcases/gateway/compliance/index.html The Energy Commission Order (if approved), will also be posted on the website.
