ENVIRONMENTAL PROTECTION AGENCY

[FRL-10396-01-R9]

Delegations of the Prevention of Significant Deterioration Air 
Permitting Program to the Maricopa County Air Quality Department and 
the Pima County Department of Environmental Quality

AGENCY: United States Environmental Protection Agency (EPA).

ACTION: Notice of delegations of authority.

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

SUMMARY: This notice announces that the Environmental Protection Agency 
(EPA), Region 9, has revised its delegation agreements with the 
Maricopa County Air Quality Department (MCAQD) and Pima County 
Department of Environmental Quality (PCDEQ) for implementation of the 
federal Clean Air Act Prevention of Significant Deterioration (PSD) 
permitting program. The revised and updated delegation agreements 
authorize these air pollution agencies in Arizona to continue to 
conduct PSD review for proposed new and modified major stationary 
sources, issue initial federal PSD permits, and revise existing federal 
PSD permits, subject to the terms and conditions of the applicable 
delegation agreement.

DATES: The revised PSD delegation agreements with the MCAQD and the 
PCDEQ became effective on October 2, 2022, and June 5, 2018, 
respectively. Pursuant to section 307(b)(1) of the Clean Air Act, 42 
U.S.C. 7607(b)(1), judicial review of these final agency actions, 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 November 30, 2022.

ADDRESSES: The revised delegation agreements are available on Region 
9's website at https://www.epa.gov/caa-permitting/air-permit-delegation-and-psd-sip-approval-status-epas-pacific-southwest-region-9. 
For additional information, please contact the person identified in the 
FOR FURTHER INFORMATION CONTACT section.

FOR FURTHER INFORMATION CONTACT: Gerardo Rios, EPA Region 9, 75 
Hawthorne Street (AIR-3-1), San Francisco, California 94105. By phone 
at (415) 972-3974, or by email at [email protected].

SUPPLEMENTARY INFORMATION: Pursuant to 40 CFR 52.21(u), the EPA signed 
revised PSD delegation agreements with the MCAQD and PCDEQ. The EPA 
signed a greenhouse gas (GHG) PSD delegation agreement with the MCAQD 
on October 2, 2022. The EPA also signed a PSD delegation agreement that 
applies to all PSD pollutants, including both attainment/unclassifiable 
pollutants and GHGs, with the PCDEQ on June 5, 2018. The delegation 
agreements authorize these Arizona air pollution agencies to implement 
the PSD program under sections 160-169 of the Clean Air Act (CAA) and 
40 CFR 52.21 for the applicable pollutants, including conducting PSD 
review and the issuance and revision of PSD permits.
    The delegation agreements set forth the terms and conditions 
according to which the agencies will implement the PSD regulations at 
40 CFR 52.21. Under the PSD program, major stationary sources of air 
pollutants must apply for and receive a permit prior to construction of 
new facilities or certain modifications to existing facilities.
    While the abovementioned Arizona air pollution agencies have been 
delegated the authority to implement and enforce the PSD program, 
nothing in the delegation agreements prohibits the EPA from enforcing 
the PSD provisions of the CAA, the PSD regulations, or the conditions 
of any PSD permit issued by the air pollution agencies.

Director, Air and Radiation Division, Region IX.
