Notice of Re-Issuance of the Prevention of Significant 
Deterioration Applicability Determination for the Carlsbad Energy 
Center Project, Carlsbad, CA

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of final action.

-----------------------------------------------------------------------

SUMMARY: This notice announces that on January 10, 2011, the EPA issued 
a determination that the proposal to modify the Encina Power Station is 
not subject to the Prevention of Significant Deterioration (PSD) permit 
program under the Clean Air Act (CAA). This determination corrects a 
typographical error in the emission data in our previous determination 
issued on October 13, 2010. Therefore, the determination issued on 
January 10, 2011 replaces the one EPA issued on October 13, 2010.

ADDRESSES: EPA's determination and other related documents used in the 
determination are available electronically on EPA's Web site at http://www.epa.gov/region9/air/permit/r9-permits-issued.html. These documents 
are also available for public inspection during normal business hours 
at the following address: EPA Region 9, 75 Hawthorne Street, San 
Francisco, California 94105. For more information or to arrange viewing 
of these documents, contact Shaheerah Kelly at (415) 947-4156 or

FOR FURTHER INFORMATION CONTACT: Shaheerah Kelly, EPA Region 9, Air 
Division (AIR-3), 75 Hawthorne Street, San Francisco, CA 94105, (415)

SUPPLEMENTARY INFORMATION: The Carlsbad Energy Center Project is a 
proposed 540 MW net (558 MW gross) combined cycle natural gas-fired 
power plant that will be built at the existing Encina Power Station in 
the city of Carlsbad in San Diego County, California. The Carlsbad 
Energy Center Project will replace three of five existing natural gas-
fired boilers located at the eastern end of the property site at the 
Encina Power Station. The Encina Power Station is owned by NRG Energy, 
Inc. (NRG), and currently has a total of five natural gas-fired 
boilers, which are allowed to use No. 6 fuel oil during curtailments, 
and three fuel oil storage tanks. The Encina Power Station is an 
existing major source, and the addition of the Carlsbad Energy Center 
Project would be a physical change to the facility.
    EPA Region 9 has authority to implement the Clean Air Act 
Prevention of Significant Deterioration Program at 40 CFR 52.21 for San 
Diego County, California. Because the Carlsbad Energy Center Project is 
a physical change to an existing major stationary source, EPA Region 9 
evaluated whether the physical change is a major modification by 
determining whether the physical change will result in a net emission 
increase for pollutants regulated under the PSD permit program. We 
received emissions information from NRG on June 5, 2009, as well as 
additional information since that time. This emissions information 
addressed the following criteria pollutants associated with the 
modification: nitrogen oxides, carbon monoxide, particulates, volatile 
organic compounds, and sulfur oxides. On October 13, 2010, we issued a 
determination that the Carlsbad Energy Center Project is not subject to 
the PSD permit program under the Clean Air Act (CAA). EPA published a 
Federal Register notice for this action on November 19, 2010 (75 FR 
70916-70917).
    It has recently come to EPA's attention that Table 2 of the October 
13, 2010 determination contained a typographical error in the emissions 
data. Specifically, EPA changed the net emission increase for nitrogen 
oxides (NOx) in Table 2 of the PSD applicability analysis from 39.2 tpy 
(which is incorrect) to 31.2 tpy. The new emission level is still below 
the PSD significant threshold for that pollutant. EPA made this 
correction and issued a corrected determination on January 10, 2011. No 
other changes to the previous determination were made. Therefore, the 
determination issued on January 10, 2011 replaces the one issued on 
October 13, 2010.
    If available, judicial review of EPA's determination may be sought 
by filing a petition for review pursuant to section 307(b)(1) of the 
CAA in the United States Court of Appeals for the Ninth Circuit within 
60 days from the date on which this notice is published in the Federal 
Register.

    Dated: January 13, 2011.

Director, Air Division, Region 9.
