that notice and comment rulemaking 

procedures are impracticable, 

unnecessary or contrary to the public 

interest (5 U.S.C. 808(2)). The EPA has 

made a good cause finding for this rule 

as discussed in the SUPPLEMENTARY

INFORMATION section. The EPA has 

determined that there is good cause for 

making this correction final without 

prior proposal. In this instance, notice 

and opportunity for comment is 

unnecessary because this action 

implements a minor, non-substantive 

technical correction that conforms the 

regulatory text to the rule’s preamble.

‘‘The absorption cross-section value stated 

in this appendix (304.39 atm¥1 cm¥1 ± 0.94 

atm¥1 cm¥1) will be used in all U.S.

AGENCY: Environmental Protection

ACTION: Notification of final action. 

SUMMARY: The Environmental Protection 

Agency (EPA) issued a final permit 

decision under title V of the Clean Air 

Act (CAA) to Deseret Bonanza and 

Transmission Co-operative (Deseret) for 

the operation of Deseret’s Uintah 

County, Utah, Bonanza Power Plant 

(Bonanza). 

DATES: EPA issued title V Permit to 

Operate No. V–UO–000004–2019.00 to 

Deseret on December 4, 2023, under 40 

CFR part 71. This permit was appealed 

to the Environmental Appeals Board by 

the Ute Tribe of Utah. The Board denied 

review of the permit on September 10, 

2024, and EPA issued the final permit 

decision on December 17, 2024. 

Pursuant to section 307(b)(1) of the 

CAA, judicial review of EPA’s final 

permit decision, to the extent it is 

available, may be sought by filing a 

petition for review in the United States 

Court of Appeals for the Tenth Circuit 

by March 17, 2025.

SUPPLEMENTARY INFORMATION: 

Throughout this document wherever 

‘‘we,’’ ‘‘us,’’ or ‘‘our’’ is used, we mean 

the EPA. This SUPPLEMENTARY

INFORMATION is arranged as follows: 

I. How can I get copies of this document 

and other related information? 

EPA has established a docket for this 

action under Docket ID No. EPA–R08– 

OAR–2019–0350. Publicly available 

docket materials are available either 

electronically through 

www.regulations.gov or in hard copy at 

the Environmental Protection Agency, 

Region 8, Air and Radiation Division, 

1595 Wynkoop Street, Denver, Colorado 

80202. This facility is open from 8:30 

a.m. to 4:30 p.m., Monday through 

Friday, excluding Federal holidays. We 

recommend that you telephone Suman 

Kunwar, Environmental Engineer, at 

(303) 312–6095 with any questions 

about reviewing the docket material 

before visiting the Region 8 office. 

II. Background 

The 1990 amendments to the CAA 

established a comprehensive air quality 

permit program under the authority of 

Title V of the CAA. Title V requires 

certain facilities that emit large amounts 

of air pollution, or that meet other 

specified criteria, to obtain an operating 

permit, known as a title V permit, after 

the source has begun to operate. This 

permit is an enforceable compilation of 

all enforceable terms, conditions, and 

limitations applicable to the source, and 

is designed to improve compliance by 

clarifying what facilities must do to 

control air pollution. EPA regulations 

implementing title V are codified at 40 

CFR part 71 for permits issued by EPA 

or its delegates, and at 40 CFR part 70 

for permits issued by states and local 

agencies pursuant to approved 

programs. A title V permit is valid for 

no more than five years and may be 

renewed in five-year-increments. 

Deseret operates a facility, Bonanza, 

in Uintah County, Utah. Bonanza is a 

coal-fired power plant located on the 

Uintah and Ouray Reservation. Coal is 

delivered to the Facility by train and is 

crushed and pulverized before being fed 

into the main boiler. The boiler 

produces steam, which powers a turbine 

to generate electricity. On December 5, 

2014, EPA Region 8 issued an initial 

title V Permit to Deseret for Bonanza 

pursuant to 40 CFR part 71. 

On December 4, 2023, EPA Region 8 

renewed Deseret’s Title V permit for a 

new five-year term. See title V Permit to 

Operate No. V–UO–000004–2019.00, 

Docket ID: EPA–R08–OAR–2019–0350. 

On January 3, 2024, the Ute Indian Tribe 

filed an appeal of the title V permit for 

Bonanza with the Environmental 

Appeals Board. The Tribe did not 

petition to review certain terms and 

conditions of the renewed title V permit 

but contended that the Region failed to 


ddrumheller on DSK120RN23PROD with RULES1
4652 Federal Register / Vol. 90, No. 10 / Thursday, January 16, 2025 / Rules and Regulations 

address the Tribe’s concerns about the 

health and environmental impacts of the 

Bonanza plant and acted contrary to 

Executive Orders and EPA policies 

regarding environmental justice and 

Tribal consultation, and contrary to the 

Federal trust responsibility to federallyrecognized Indian Tribes. In addition, 

the Tribe asserted that EPA abused its 

discretion and violated the Federal trust 

responsibility by not providing the 

results of an investigation identifying 

potential non-compliance with coal 

combustion residual requirements 

under the Resource Conservation and 

Recovery Act (‘‘RCRA’’) until after the 

CAA title V permit was issued. 

Consequently, under 40 CFR 

71.11(i)(2)(ii), the effective date of the 

permit was delayed. 

III. Effect of this Action 

On September 10, 2024, the EAB 

denied the petition for review. See In re 

Deseret Generation and Transmission 

Co-operative Bonanza Power Plant, 

Permit No. V–UO–000004–2019.00, 

CAA Appeal No. 24–01 (EAB, 

September 10, 2024) (Order Denying 

Review). The Tribe requested that the 

EAB reconsider its Order Denying 

Review and on November 8, 2024, the 

EAB denied the Tribe’s Motion for 

Reconsideration. Following the EAB’s 

action, pursuant to 40 CFR 

124.19(l)(2)(i), the EPA issued a final 

permit decision on December 17, 2024. 

The final title V permit is effective 

immediately and will expire on 

December 17, 2029.

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is taking final action to 

approve revisions to the Maricopa 

County Air Quality Department 

(MCAQD or ‘‘County’’) portions of the 

Arizona State Implementation Plan 

(SIP). These revisions concern the 

County’s reasonably available control 

technology (RACT) demonstration for 

the aerospace coating category and 

negative declarations for the 2008 8- 

hour ozone National Ambient Air 

Quality Standards (NAAQS or 

‘‘standards’’) in the portion of the 

Phoenix-Mesa ozone nonattainment area 

regulated by the MCAQD, as well as a 

rule covering emissions of volatile 

organic compounds (VOCs) from surface 

coatings and industrial adhesives. We 

are also approving a local rule that 

regulates these emission sources under 

the Clean Air Act (CAA or ‘‘the Act’’). 

DATES: This rule is effective February 

18, 2025. 

ADDRESSES: The EPA has established a 

docket for this action under Docket ID 

No. EPA–R09–OAR–2022–0607. All

I. Proposed Action and Interim Final 

Determination 

On August 4, 2022 (87 FR 47663), the 

EPA proposed to approve a RACT 

certification for Aerospace 

Manufacturing and Rework Operations, 

Rule 336 ‘‘Surface Coating Operations 

and Industrial Adhesive Application 

Processes,’’ and negative declarations 

for the 2008 8-hour ozone NAAQS. The 

following table lists the documents that 

were submitted by the Arizona 

Department of Environmental Quality 

(ADEQ) for incorporation into the 

Arizona SIP and were the subject of our 

August 4, 2022 proposed rulemaking 

action. 

Local agency Document Adopted Submitted 

MCAQD .............................................. Maricopa County Reasonably Available Control Technology (RACT) Certification for Volatile Organic Compound (VOC) Emissions from Aerospace 

Manufacturing and Rework Operations In Maricopa County June 2021.

06/23/21 06/30/21 

MCAQD .............................................. Rule 336 Surface Coating Operations and Industrial Adhesive Application 

Processes.

09/01/21 09/17/21 

MCAQD .............................................. Negative Declarations for Three Coating Categories Listed in the 2008 

Control Techniques Guidelines for Miscellaneous Metal and Plastic Parts 

Coatings.

09/01/21 09/17/21 

We proposed to approve the RACT 

certification, rule, and negative 

declarations because we determined 

that they comply with the relevant CAA 

requirements. Our proposed action 

contains more information on the RACT 

certification, rule, negative declarations, 

and our evaluation. On the same day, 

we also made an interim final 

determination (87 FR 47630) that the 

submittal from the ADEQ corrected SIP 

deficiencies from a previous submittal, 

allowing us to defer the imposition of 

sanctions resulting from our previous 

disapproval action concerning ozone 

nonattainment requirements.
