Energy Commission Releases Preliminary
Assessment on Walnut Creek Energy Park

Sacramento - The Energy Commission today released the Preliminary Staff Assessment on the proposed Walnut Creek Energy Park in Los Angeles County.

The document concludes that the project could be licensed with no significant unmitigated impacts if noise and air quality concerns identified by staff are resolved.

The Preliminary Staff Assessment does not serve as a final decision. Comments on the document may be submitted by January 30, 2007. Energy Commission staff will conduct one or more workshops in January 2007 to discuss the preliminary staff document and resolve any remaining issues before releasing a Final Staff Assessment.

The Final Staff Assessment will serve as the staff's testimony at Evidentiary Hearings to be held by the Committee of two Commissioners reviewing this case. The Committee will then issue a proposed decision based on the evidence presented at the hearings. The proposed decision will be presented to the full Energy Commission for a final decision.

The Preliminary Staff Assessment on the proposed power plant is available on the Commission's Web site at:


Walnut Creek Energy Park is a nominal 500-megawatt simple-cycle plant on an 11.48-acre parcel in the City of Industry. A warehouse used to store and recycle electronic waste currently occupies the site.

The power plant proposed by a subsidiary of Edison Mission Energy is within an area of warehouses, manufacturing companies, railroads and truck yards. Residential areas are located on the northern and southern parts of the proposed energy park.

The Energy Commission will work jointly with the City of Industry, Los Angeles County, the South Coast Air Quality Management District, the U.S. Environmental Protection Agency, the California Independent System Operator and others to develop the final staff document. Staff conclusions on air quality and noise are currently incomplete. Discussions are ongoing on the potential impacts and mitigation measures among Energy Commission staff, the applicant and other interested parties

Public involvement is an important part of the Energy Commission power plant licensing and amendment processes. To find out how to participate in this case, contact the Energy Commissions Public Adviser, Margret J. Kim, at (916) 654-4489, (800) 822-8228, or by e-mail at:
