Docket No. 98-AFC-1

On June 15,1998, the Pittsburg District Energy Facility, Limited Liability Company (LLC), filed an Application for Certification (AFC) with the California Energy Commission (Energy Commission) to construct and operate the Pittsburg District Energy Facility (PDEF). The PDEF will be providing process steam to USS-Posco Industries. Electrical energy produced from the proposed power plant will be sold to California's regional power pool and other electricity consumers. The PDEF electric generating plant and related facilities, such as the electric transmission line, natural gas pipeline and water lines are under the Energy Commission's jurisdiction. The power plant certification process examines engineering and environmental aspects of power plant proposals, and contains requirements similar to those contained in the California Environmental Quality Act (CEQA).



The PDEF will be located on a 12 acre site in on East 3rd Street, west of the intersection of E. 3rd and Columbia in the City of Pittsburg, in eastern Contra Costa County. The site is on the northwest corner of property owned by USS-Posco Industries. See the map on the following page for the location of the project.


The applicant has proposed a combined cycle combustion turbine generator (CTG) design with a nominal capacity of 500 megawatts (MW). The design would consist of of two trains of "F" class CTG machines with either one or two steam turbine generators. Natural gas is combusted in the combustion turbine generators, which converts the thermal energy into mechanical energy required to drive the compressor and electric generator. The combustion turbine trains will include exhaust stacks and step-up transformers, heat recovery steam generators (HRSG) units, steam turbine generator units and their transformers, and water treatment and cooling towers. A 115 kV high voltage switchyard will be located on the east side of the project site. Reclaimed water for turbine cooling will be supplied from the Delta Diablo Wastewater Treatment Facility located in the City of Antioch.

In support of the City of Pittsburg's effort to reroute existing marine terminal truck traffic as well as provide improved access to the project site, the PDEF project has sponsored and will construct a new Truck Bypass Road which will be approximately .75 mile long. It will connect E. 14th Street, near the existing intersection of Columbia Street and E. 14th, to Harbor Street, near the existing intersection of Santa Fe Boulevard and Harbor (see project location map). Nitrogen oxide (NOx) emissions from the combustion process will be reduced to 2.5 parts per million by volume dry (ppmvd), or less, at 15 percent oxygen by utilizing dry low NOx combustion technology and a selective catalytic reduction (SCR) system . The SCR system will use aqueous ammonia for the reduction process.

Linear electric facilities associated with the project include: a new 1.6 mile double circuit 115 kilovolt (kV) overhead electric transmission line to connect the project to Pacific Gas & Electric's (PG&E) existing 115kV transmission line on Columbia Street; and on the same towers as the above double circuit line, a new 1.1 mile single circuit 115 kV line to connect the PDEF with the USS-Posco Industries plant. Sections of these new lines will parallel existing 115 kV lines.

Pipeline facilities associated with the project include: a potable water supply line approximately 500 feet long; a gas pipeline approximately 3.6 miles long; a sewer line approximately 500 feet long; and a reclaimed water line approximately 2 miles long. All of the pipeline facilities will be buried underground. The engineering and environmental details of the proposed project are contained in the AFC.


The purpose of the AFC process is to enable the Energy Commission to make a determination regarding the need for the project, and to assess the project's impact on environmental quality and public health and safety. The first step in the Energy Commission's siting process will be data adequacy review. The Energy Commission's Executive Director will make a recommendation to the Energy Commission regarding whether the AFC complies with the data requirements contained in the Energy Commission's data adequacy regulations (Cal. Code Regs., tit. 20, § 1704, Appendix B). The Energy Commission has 45 days from June 15, 1998, to act on this recommendation. An Energy Commission decision on data adequacy is scheduled for the Energy Commission's July 29, 1998, business meeting. If the AFC is deemed adequate, the Energy Commission will appoint a committee of two Commissioners to review all matters related to this proceeding and the discovery phase will begin.

Staff will notice and conduct public workshops on data discovery and issue resolution. The next major milestone occurs when staff files its preliminary staff assessment (PSA), generally around 165 days after the AFC is accepted. Staff will conduct public workshops on its PSA to obtain comments and recommendations from the public, agencies and parties to the case. Based on those comments and recommendations, staff will issue its final staff assessment (FSA) which becomes its testimony for the formal evidentiary hearings held by the Committee to accept evidence on the case. The Committee will then issue the Presiding Members Proposed Decision, and the public and agencies will have an opportunity to comment on the proposed decision.


Copies of the AFC document are available for public inspection at public libraries in the cities of Pittsburg, Antioch, and Pleasant Hill as follows:

Contra Costa County Library
Pittsburg Branch

Antioch Branch
501 W.18th
Antioch, CA 94509

Contra Costa County Central Library
1750 Oak Park Blvd.
Pleasant Hill, CA 94523

Copies are also available at the Energy Commission Library in Sacramento, the California State Library in Sacramento, and at public libraries in Los Angeles, San Francisco, San Diego, Fresno, and Eureka. In addition, copies will be distributed to those public agencies which have or would have jurisdiction but for the Energy Commission's exclusive authority to certify sites and related facilities. If you want additional information on how to obtain a copy of the AFC for review, please refer to the contacts in the public participation section below.


Over the next twelve months the Energy Commission will conduct a number of public workshops and hearings on the proposal. The purpose of these workshops include: data adequacy review, data discovery, issue resolution, identification of appropriate mitigation and compliance monitoring techniques, and review and comment on staff and applicant filings for the project. These workshops will provide the public, agencies and other parties the opportunity to ask questions and express concerns about the proposed project. The Energy Commission will issue notices for these workshops and hearings, normally 14 days, but in no case later than 10 days prior to the meeting. If you are not currently receiving these notices and want to be placed on the mailing list, please contact Gina M. Mortholé, Project Secretary, at (916) 654-4235.

There are various ways in which members of the public can participate in the Energy Commission's proceedings. If you want information on how to participate in the Energy Commission's review of the project, please contact Ms. Roberta Mendonca, the Energy Commission's Public Adviser, at (916) 654-4489, or toll free in California at (800) 822-6228. Technical or project schedule questions should be directed to Eileen Allen, Siting Project Manager, in the Energy Facilities Siting & Environmental Protection Division, at (916) 654-4082, or email at The status of the project, copies of notices and other relevant documents will also be available via the Energy Commission's Internet page at News media inquiries should be directed to Assistant Executive Director, Claudia Chandler, at (916) 654-4989.

This notice of receipt has been mailed to all parties that requested to be placed on the mailing list during prefiling and to property owners located within one mile of the project site or within 500 feet of any of the project related linear facilities. By being on the mailing list, you will receive notices of all project related activities and notices that documents related to the project's approval are available for review. If you want your name removed from the mailing list, please contact Gina M.
