Re: Final PSD Permit for Victorville 2 Hybrid Power Project 

Dear Mr. Roberts: 

In accordance with the Clean Air Act, as amended (42 U.S.C.7401 et seq.), the United 

States Environmental Protection Agency (EPA) has reviewed your application to construct a 563 

megawatt hybrid solar and natural gas-fired combined cycle power plant known as the 

Victorville 2 Hybrid Power Project in Victorville, San Bernardino County, California. After 

reviewing the application, EPA drafted a proposed Prevention of Significant Deterioration (PSD) 

permit and public notice of our decision to allow construction of the facility pursuant to the 

conditions in the proposed PSD permit, iffinalized. The public notice requested public comment 

regarding our proposed action and the conditions in the proposed PSD permit. We published the 

public notice requesting comments on June 6, 2008, in the Victorville Daily Press. EPA also sent 

the public notice requesting comments on our proposed action to several parties, including those 

specified in 40 CFR Part 124. EPA made the proposed PSD permit and Ambient Air Quality 

Impact Report available at the Mojave Desert Air Quality Management District, the Victorville, 

Apple Valley, and Adelanto Public Libraries, on EPA's website and at our Region IX office in 

San Francisco, CA. 

EPA received two comment letters on July 7,2008, one from Adams Broadwell Joseph & 

Cardozo (ABJC), on behalf of California Unions for Reliable Energy (CURE), and one from 

ENSR Corporation (ENSR), on behalf of the City of Victorville and Inland Energy. On October 

7,2008, ENSR withdrew its comment letter on the proposed permit, and on June 8, 2009, ABJC 

withdrew its comment letter. EPA received no other comments regarding the proposed action 

and PSD permit. Because ABJC and ENSR withdrew their comment letters, EPA has determined 

it is not necessary to respond to their comments in issuing the final PSD permit allowing 

construction of the facility. Before AB1C withdrew its comment letter on June 8,2009, EPA's 

policy with respect to evaluating particulate matter with a diameter of 2.5 microns or less 

changed. As described in an addendum to the Ambient Air Quality Impact Report, EPA 

requested the applicant to provide some additional analysis. Our evaluation of the additional 

analysis did not result in any revised conditions and supported the conditions in the proposed 

PSD permit. 

Printed on Recycled Paper 
The final PSD permit and addendum to the Ambient Air Quality Impact Report are 

enclosed. These documents, along with other documents relevant to the final PSD permit, and 

the index for the administrative record are also available online at \v\",w.regulations.flO\' (Docket 

10 # EPA-R09-0AR-2008-0765), with a link from our website at 

www.epa.gov/region09/air/permit/r9-permits-issued.html#psd. 

This final PSD permit shall be effective on the date of issuance pursuant to 40 

CFR 124.15(b)(3). If you have any questions regarding this matter, please contact Anita Lee of 

our Permits office at (415) 972-3958. 

Sincerely,
