OF A FINAL DECISION TO ISSUE A PSD PERMIT THAT REGULATES THE 

EMISSION OF AIR POLLUTANTS 

PALMDALE HYBRID POWER PROJECT 

PERMIT APPLICATION NO. SE 09-01 

In August 2011, the United States Environmental Protection Agency, Region 9 (EPA) 

requested public comment on our proposal to issue a Prevention of Significant 

Deterioration (PSD) permit authorizing the construction and operation of a 570 megawatt 

(MW) natural gas-fired combined-cycle power plant, with an integrated 50 MW solarthermal plant, known as the Palmdale Hybrid Power Project (PHPP or Project), in 

Palmdale, California. 

During the public comment period, which ended on September 14, 2011, EPA received 

written and oral comments regarding its proposed PSD permitting action for the Project. 

EPA has carefully reviewed each of the comments submitted and, after consideration of 

the expressed views of all commenters, the pertinent Federal statutes and regulations, and 

additional material relevant to the application and contained in our Administrative 

Record, EPA has made a decision in accordance with 40 CFR 52.21 to issue a final PSD 

permit to the City of Palmdale for the Project. The final permit was signed on October 18, 

2011. 

Key portions of the Administrative Record for this decision (including the final permit, 

all public comments, EPA’s responses to the public comments, and additional supporting 

information) are available online at www.regulations.gov (Docket ID # EPA-R09-OAR2011-0560), with a link from our website at www.epa.gov/region09/air/permit/r9-

Administrative Record for this action, may also be viewed in person, Monday through 

Friday from 9:00 AM to 4:00 PM, at the EPA Region 9 address below. Due to building

The contact information above may also be used to request copies of other portions of the

Within 30 days after the service of notice announcing this final permit decision, any 
person who filed comments on the proposed permit for the Project or participated in any 

of the public hearings for the Project may petition EPA’s Environmental Appeals Board 

(EAB) to review any condition of the final permit. Persons who did not file comments or 

participate in the public hearings may petition for administrative review only to the extent 

of changes from the proposed to the final permit decision. The petition must include a 

statement of the reason(s) for requesting review by the EAB, including a demonstration 

that any issues being raised were raised during the public comment period to the extent 

required by the regulations at 40 CFR Part 124 and when appropriate, a showing that the 

conditions in question are based on 1) a finding of fact or conclusion of law which is 

erroneous, or 2) an exercise of discretion or an important policy consideration which the 

EAB should, in its discretion, review. Please see 40 CFR 124.19 and visit 

http://www.epa.gov/eab/ for important information regarding the procedures for appeal of 

a PSD permit decision to the EAB. 

EPA’s PSD permit for the Project shall take effect thirty (30) days from the date of 

service of notice of this permit decision unless a petition for review is properly and 

timely filed with the EAB. In the event that a petition for review is filed with the EAB, 

construction of the facility is not authorized under this PSD permit until resolution of the 

EAB petition(s).
