ENVIRONMENTAL PROTECTION AGENCY

[FRL-10227-01-R9]


Clean Air Act Operating Permits; Arizona; Petitions To Object to 
Permits for the Coronado Generating Station, Desert Basin Generating 
Station, and Agua Fria Generating Station

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of final action.

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

SUMMARY: The Environmental Protection Agency (EPA) Administrator signed 
three Orders granting in part and denying in part petitions to object 
to three Clean Air Act (CAA) title V operating permits issued to power 
plants in Arizona. The Orders relate to the operating permits for 
Coronado Generating Station, issued by the Arizona Department of 
Environmental Quality (ADEQ); Desert Basin Generating Station, issued 
by the Pinal County Air Quality Control District (PCAQCD); and Agua 
Fria Generating Station issued by the Maricopa County Air Quality 
Department (MCAQD). The Orders respond to petitions submitted by the 
Sierra Club (the ``Petitioner'') requesting that the EPA object to the 
issuance of the operating permits for these facilities. The Orders 
constitute final action on the request that the Administrator object to 
the issuance of these CAA title V operating permits.

DATES: Pursuant to section 307(b)(1) of the Clean Air Act, 42 U.S.C. 
7607(b)(1), judicial review of this final agency action, to the extent 
it is available, may be sought by filing a petition for review in the 
United States Court of Appeals for the Ninth Circuit within 60 days of 
September 30, 2022.

ADDRESSES: Copies of the petitions and Orders are available at https://www.epa.gov/title-v-operating-permits/title-v-petition-database. For 
additional information, please contact the person identified in the FOR 
FURTHER INFORMATION CONTACT section.

FOR FURTHER INFORMATION CONTACT: Lisa Beckham, EPA Region 9, 75 
Hawthorne Street (AIR-3-1), San Francisco, California 94105. By phone 
at (415) 972-3811, or by email at [email protected].

SUPPLEMENTARY INFORMATION: The CAA affords the EPA a 45-day period to 
review and, as appropriate, the authority to object to operating 
permits proposed by state and local permitting authorities under title 
V of the CAA, 42 U.S.C. 7661-7661f. Section 505(b)(2) of the CAA and 40 
CFR 70.8(d) authorize any person to petition the EPA Administrator to 
object to a title V operating permit within 60 days after the 
expiration of the EPA's 45-day review period if the EPA has not 
objected on its own initiative. Petitions must be based only on 
objections to the permit that were raised with reasonable specificity 
during the public comment period provided by the permitting authority, 
unless the petitioner demonstrates that it was impracticable to raise 
these issues during the comment period or the grounds for the issues 
arose after the comment period closed.
    As listed below, the EPA received and responded to three petitions 
from the Petitioner that were submitted pursuant to section 505(b)(2) 
of the CAA and 40 CFR 70.8(d) for title V operating permits issued to 
three electric power generating facilities in Arizona.

a petition requesting that the EPA object to the CAA title V operating

June 14, 2022, the EPA issued an Order responding to the petition by 
granting the petition in part and denying the petition in part.
    Desert Basin Generating Station. On February 8, 2022, the EPA 
received a petition requesting that the EPA object to the CAA title V 
operating permit issued by the PCAQCD for the Salt River Project's 
Desert Basin Generating Station (Permit No. V20678.R02) in Pinal 
County, Arizona. On July 28, 2022, the EPA issued an Order responding

petition in part.
    Agua Fria Generating Station. On February 28, 2022, the EPA 
received a petition requesting that the EPA object to the CAA title V

Arizona. On July 28, 2022, the EPA issued an Order responding to the 
petition by granting the petition in part and denying the petition in 
part.
    The Orders provide additional information, including a summary of 
the claims raised and the EPA's detailed basis for its determination to 
grant or deny the claims raised by the Petitioner. Please see the
