Attainment year ozone season means 

the full ozone season immediately 

preceding a nonattainment area’s 

maximum attainment date. 

CAA means the Clean Air Act as 

codified at 42 U.S.C. 7401–7671q 

(2010). 

Former attainment date means any 

attainment date associated with the

of title I of the CAA preceding 

reclassification from a lower 

classification to a higher classification. 

Former classification means any 

classification under subpart 2 of part D 

of title I of the CAA preceding 

reclassification from a lower 

classification to a higher classification. 

Higher classification/lower 

classification means for purposes of 

determining which classifications are 

higher or lower, the classifications are 

ranked from lowest to highest as 

follows: Marginal; Moderate; Serious; 

Severe-15; Severe-17; and Extreme. 

I/M refers to the inspection and 

maintenance programs for in-use 

vehicles required under the 1990 CAA 

Amendments and defined by subpart S 

of 40 CFR part 51. 

Initially classified means the first 

nonattainment classification that 

becomes effective for an area for a 

specific ozone NAAQS and does not 

include reclassification to another 

classification for that specific NAAQS. 

Initially designated means the first 

designation to nonattainment that 

becomes effective for an area for a 

specific ozone NAAQS. 

Ozone season means for each state (or 

portion of a state), the ozone monitoring 

season as defined in 40 CFR part 58, 

appendix D, section 4.1(i) for that state 

(or portion of a state). 

§ 51.1401 Applicability of part 51. 

The provisions in subparts A through 

Y, AA, and CC of this part apply to 

reclassified nonattainment areas for 

purposes of the ozone NAAQS to the 

extent they are not inconsistent with the 

provisions of this subpart. 

§ 51.1402 SIP submission and control 

measure implementation deadlines for 

reclassified ozone nonattainment areas. 

(a) Deadlines for applicable 

requirements pursuant to a 

reclassification as Moderate, Serious, or 

Severe that are 18 months or more after 

the effective date of reclassification will 

apply to such reclassified area as though 

the area were initially designated at that 

classification. 

(b) Deadlines for applicable 

requirements pursuant to a 

reclassification as Moderate, Serious, or 

Severe, where the deadline that would 

have applied had the area been initially 

classified at the new classification level 

at the time of initial nonattainment area 

designations is less than 18 months after 

the effective date of reclassification. 

(1) SIP submission deadlines. (i) For 

all SIP revisions required pursuant to 

reclassification (except SIPs addressing 

CAA section 185 fee programs), the SIP 

revision deadline is 18 months after the 

effective date of the relevant 

reclassification or January 1 of the 

attainment year, whichever is earlier, 

unless the Administrator establishes a 

different deadline in a separate action. 

(ii) For SIP revisions addressing CAA 

section 185 fee programs required 

pursuant to reclassification, the SIP 

revision deadline is 36 months after the 

effective date of the relevant 

reclassification or January 1 of the 

attainment year, whichever is earlier, 

unless the Administrator establishes a 

different deadline in a separate action. 

(2) Control measure implementation 

deadlines. (i) For RACT required 

pursuant to reclassification, the state 

shall provide for implementation of 

such RACT as expeditiously as 

practicable, but no later than 18 months 

after the RACT SIP submittal deadline 

or the beginning of the attainment year 

ozone season associated with the area’s 

new attainment deadline, whichever is 

earlier, unless the Administrator 

establishes a different deadline in a 

separate action. 

(ii) For the required I/M program 

pursuant to reclassification, the state 

shall provide for full implementation of 

such I/M program as expeditiously as 

practicable, but no later than 4 years 

after the effective date of the relevant 

reclassification, unless the I/M program 

is needed for attainment by the 

attainment date or RFP, in which case 

the state shall provide for full 

implementation of such I/M program no 

later than the beginning of the 

attainment year ozone season. 

§ 51.1403 Applicability of ozone SIP 

requirements for former classification after 

reclassification. 

(a) Upon the effective date of 

reclassification, the requirements of any 

subpart of this part with respect to 

ozone nonattainment planning 

applicable to the area for the former 

classification shall apply as follows: 

(1) Unless specified in paragraph 

(a)(2) or (3) of this section, the 

requirement is unaffected by 

reclassification and continues to be 

required for the former classification. 

(2) The following requirements are no 

longer applicable with respect to the 

former attainment date: 

(i) A SIP revision to demonstrate 

attainment by such date. 

(ii) A SIP revision demonstrating 

adoption of all RACM necessary to 

demonstrate attainment with respect to 

such date. 

(3) If the reclassification became 

effective prior to the former attainment 

date pursuant to CAA section 181(b)(3), 

the plan requirement for contingency 

measures for failure to attain by such 

date is no longer applicable with respect 

to the former attainment date. 

(b) Nothing in this section shall affect 

the requirements applicable to the 

nonattainment area under its currently 

applicable classification and attainment 

date.

SUPPLEMENTARY INFORMATION: 

I. Background 

Each State has a SIP containing the 

control measures and strategies used to 

attain and maintain the national 

ambient air quality standards (NAAQS). 

The SIP is extensive, containing such 

elements as air pollution control 

regulations, emission inventories, 

monitoring networks, attainment 

demonstrations, and enforcement 

mechanisms. 

Each State must formally adopt the 

control measures and strategies in the 

SIP after the public has had an 

opportunity to comment on them and 

then submit the proposed SIP revisions 

to the EPA. Once these control measures 

and strategies are approved by EPA, and 

after notice and comment, they are 

incorporated into the federally approved 

SIP and are identified in part 52, 

‘‘Approval and Promulgation of 

Implementation Plans,’’ of title 40 of the 

Code of Federal Regulations (40 CFR 

part 52). The full text of the State 

regulation approved by the EPA is not 

reproduced in its entirety in 40 CFR part 

52 but is ‘‘incorporated by reference.’’ 

This means that the EPA has approved 

a given State regulation or specified 

changes to the given regulation with a 

specific effective date. The public is 

referred to the location of the full text 

version should they want to know 

which measures are contained in a 

given SIP. The information provided 

allows the EPA and the public to 

monitor the extent to which a State 

implements a SIP to attain and maintain 

the NAAQS and to take enforcement 

action for violations of the SIP. 

The SIP is a living document which 

the State can revise as necessary to 

address the unique air pollution 

problems in the State. Therefore, the 

EPA from time to time must take action 

on proposed revisions containing new 

or revised State regulations. A 

submission from a State can revise one 

or more rules in their entirety, or 

portions of rules. The State indicates the 

changes in the submission (such as by 

using redline/strikethrough text) and the 

EPA then takes action on the requested 

changes. The EPA establishes a docket 

for its actions using a unique Docket 

Identification Number, which is listed 

in each action. These dockets and the 

complete submission are available for 

viewing on www.regulations.gov. 

On May 22, 1997 (62 FR 27968), the 

EPA revised the procedures for 

incorporating by reference, into the 

CFR, materials approved by the EPA 

into each SIP. These changes revised the 

format for the identification of the SIP 

in 40 CFR part 52, streamlined the 

mechanisms for announcing the EPA 

approval of revisions to a SIP, and 

streamlined the mechanisms for the 

EPA’s updating of the IBR information 

contained for each SIP in 40 CFR part 

52. The revised procedures also called 

for the EPA to maintain ‘‘SIP 

Compilations’’ that contain the federally 

approved regulations and sourcespecific permits submitted by each State 

agency. 

The EPA generally updates these SIP 

Compilations every few years. Under 

the revised procedures, the EPA must 

periodically publish an informational 

document in the rules section of the 

Federal Register notifying the public 

that updates have been made to a SIP 

Compilation for a particular State. The 

EPA began applying the 1997 revised 

procedures to the Alaska SIP on April 

10, 2014 (79 FR 19820). The EPA 

subsequently published updates to the 

IBR materials for Alaska on December 8, 

2017 (82 FR 57836) and December 12, 

2022 (87 FR 75932). 

A. Approved and Incorporated by 

Reference Regulatory Materials 

Since the last IBR update, the EPA 

approved and incorporated by reference 

regulatory materials into the Alaska SIP 

at 40 CFR 52.70(c): 

1. Action on March 22, 2023 (88 FR 

2873): 

• 18 AAC 50.035 (documents, 

procedures, and methods adopted by 

reference), except (a)(6), (a)(9), and 

(b)(4) (State effective 4/16/2022); 

• 18 AAC 50.040 (Federal standards 

adopted by reference), except (a), (b), 

(c), (d), (e), (g), (j), and (k) (State 

effective 4/16/2022); 

• 18 AAC 50.270 (electronic 

submission requirements) (State 

effective 9/7/2022); 

• 18 AAC 50.275 (consistency of 

reporting methodologies) (State effective 

9/7/2022); and 

• 18 AAC 50.400 (permit 

administration fees), except (a), (b), (c), 

and (i) (State effective 9/7/2022). 

2. Action on August 9, 2023 (88 FR 

53793): 

• 18 AAC 50.025 (establishing 

geographic areas that may need 

additional pollution control because of 

special circumstances) (State effective 4/ 

16/2022); 

• 18 AAC 50.502 (establishing which 

types of stationary sources must obtain 

minor construction and/or operating 

permits) (State effective 4/14/2022); 

• 18 AAC 50.540 (outlining the 

required contents of an application for 

a minor construction and/or operating 

permit) State effective 4/14/2022); and 

• 18 AAC 50.542 (establishing the 

process the state uses to review permit 

applications from sources, conduct 

public notice and comment, and issue 

permits) (State effective 4/14/2022). 

3. Action on December 5, 2023 (88 FR 

84626): 

• 18 AAC 50.075 (solid fuel-fired 

heating device visible emission 

standards), except (d)(2) (State effective 

11/18/2020). 

B. Regulatory Materials Removed From 

Incorporation by Reference 

Since the last IBR update, the EPA 

also removed the following regulatory 

materials from the Alaska SIP at 40 CFR 

52.70(c): 

1. Action on August 9, 2023 (88 FR 

53793): 

• 18 AAC 50.080 (regulating water 

vapor emissions from industrial sources 

that may form ice fog) (State effective 1/ 

18/1997). 

II. EPA Action 

In this action, the EPA is providing 

notification of an update to the 

materials incorporated by reference into 

the Alaska SIP as of October 1, 2024, 

and identified in 40 CFR 52.70(c). This 

update includes SIP materials submitted 

by Alaska and approved by the EPA 

since the last IBR update. See 87 FR 

75932 (December 12, 2022). 

III. Good Cause Exemption 

The EPA has determined that this 

action falls under the ‘‘good cause’’ 

exemption in section 553(b)(3)(B) of the 

Administrative Procedure Act (APA) 

which, upon finding ‘‘good cause,’’ 

authorizes agencies to dispense with 

public participation and section 

553(d)(3) which allows an agency to 

make an action effective immediately 

(thereby avoiding the 30-day delayed 

effective date otherwise provided for in 

the APA). This administrative action 

simply codifies provisions which are 

already in effect as a matter of law in 

Federal and approved State programs, 

makes corrections and clarifying 

changes to the tables in the CFR, and 

makes ministerial changes to the 

prefatory heading to the tables in the 

CFR. Under section 553 of the APA, an 


KHAMMOND on DSK9W7S144PROD with RULES
5680 Federal Register / Vol. 90, No. 11 / Friday, January 17, 2025 / Rules and Regulations 

agency may find good cause where 

procedures are ‘‘impracticable, 

unnecessary, or contrary to the public 

interest.’’ Public comment for this 

administrative action is ‘‘unnecessary’’ 

and ‘‘contrary to the public interest’’ 

since the codification (and corrections) 

only reflect existing law. Immediate 

notice of this action in the Federal 

Register benefits the public by 

providing the public notification of the 

updated Alaska SIP Compilation and 

notification of corrections to the Alaska 

‘‘Identification of Plan’’ portion of the 

CFR. Further, pursuant to section 

553(d)(3), making this action 

immediately effective benefits the 

public by immediately updating both 

the SIP Compilation and the CFR 

‘‘Identification of plan’’ section (which 

includes table entry corrections). 

IV. Incorporation by Reference 

In this document, the EPA is 

finalizing regulatory text that includes 

incorporation by reference. In 

accordance with requirements of 1 CFR 

51.5, the EPA is finalizing the 

incorporation by reference of 

regulations promulgated by Alaska, 

previously approved by the EPA and 

federally effective before October 1, 

2024, contained in 40 CFR 52.70(c), EPA 

approved laws and regulations, 

described in section II. of this preamble. 

The EPA has made, and will continue 

to make, these materials generally 

available through www.regulations.gov 

and at the EPA Region 10 Office (please 

contact the person identified in the FOR

FURTHER INFORMATION CONTACT section of 

this preamble for more information). 

V. Statutory and Executive Order 

Reviews 

Under the Clean Air Act (CAA), the 

Administrator is required to approve a 

SIP submission that complies with the 

provisions of the CAA and applicable 

Federal regulations. 42 U.S.C. 7410(k); 

40 CFR 52.02(a). Thus, in reviewing SIP 

submissions, The EPA’s role is to 

approve State choices, provided that 

they meet the criteria of the CAA. 

Accordingly, this action merely 

addresses administrative requirements 

related to previously approved State law 

found to meet Federal requirements and 

does not impose additional 

requirements beyond those previously 

imposed by State law. For that reason, 

this action: 

• Is not a ‘‘significant regulatory 

action’’ subject to review by the Office 

of Management and Budget under 

Executive Orders 12866 (58 FR 51735, 

October 4, 1993) and 14094 (88 FR 

21879, April 11, 2023); 

• Does not impose an information 

collection burden under the provisions 

of the Paperwork Reduction Act (44 

U.S.C. 3501 et seq.); 

• Is certified as not having a 

significant economic impact on a 

substantial number of small entities 

under the Regulatory Flexibility Act (5 

U.S.C. 601 et seq.); 

• Does not contain any unfunded 

mandate or significantly or uniquely 

affect small governments, as described 

in the Unfunded Mandates Reform Act 

of 1995 (Pub. L. 104–4); 

• Does not have federalism 

implications as specified in Executive 

Order 13132 (64 FR 43255, August 10, 

1999); 

• Is not subject to Executive Order 

13045 (62 FR 19885, April 23, 1997) 

because it is an administrative action 

related to State program approval; 

• Is not a significant regulatory action 

subject to Executive Order 13211 (66 FR 

28355, May 22, 2001); and 

• Is not subject to requirements of 

section 12(d) of the National 

Technology Transfer and Advancement 

Act of 1995 (15 U.S.C. 272 note) because 

application of those requirements would 

be inconsistent with the Clean Air Act. 

In addition, the SIP is not approved 

to apply on any Indian reservation land 

or in any other area where the EPA or 

an Indian Tribe has demonstrated that a 

Tribe has jurisdiction. In those areas of 

Indian country, the rule does not have 

Tribal implications and it will not 

impose substantial direct costs on Tribal 

governments or preempt Tribal law as 

specified by Executive Order 13175 (65 

FR 67249, November 9, 2000). 

Executive Order 12898 (Federal 

Actions To Address Environmental 

Justice in Minority Populations and 

Low-Income Populations, 59 FR 7629, 

February 16, 1994) directs Federal 

agencies to identify and address 

‘‘disproportionately high and adverse 

human health or environmental effects’’ 

of their actions on communities with 

environmental justice (EJ) concerns to 

the greatest extent practicable and 

permitted by law. Executive Order 

14096 (Revitalizing Our Nation’s 

Commitment to Environmental Justice 

for All, 88 FR 25251, April 26, 2023) 

builds on and supplements Executive 

Order 12898 and defines EJ as, among 

other things, the just treatment and 

meaningful involvement of all people, 

regardless of income, race, color, 

national origin, or Tribal affiliation, or 

disability in agency decision-making 

and other Federal activities that affect 

human health and the environment.’’ 

The CAA and applicable implementing 

regulations neither prohibit nor require 

an EJ evaluation. This CAA 

administrative action to update the 

incorporation by reference of previously 

submitted and approved State 

regulatory materials, the EPA did not 

consider EJ in this action. 

The Congressional Review Act, 5 

U.S.C. 801 et seq., as added by the Small 

Business Regulatory Enforcement 

Fairness Act of 1996, generally provides 

that before a rule may take effect, the 

agency promulgating the rule must 

submit a rule report, which includes a 

copy of the rule, to each House of the 

Congress and to the Comptroller General 

of the United States. The EPA will 

submit a report containing this action 

and other required information to the 

U.S. Senate, the U.S. House of 

Representatives, and the Comptroller 

General of the United States prior to 

publication of the rule in the Federal 

Register. A major rule cannot take effect 

until 60 days after it is published in the 

Federal Register. This action is not a 

‘‘major rule’’ as defined by 5 U.S.C. 

804(2). 

The EPA also believes that the 

provisions of section 307(b)(1) of the 

CAA pertaining to petitions for judicial 

review are not applicable to this action. 

This is because prior EPA rulemaking 

actions for each individual component 

of the Alaska SIP Compilation 

previously afforded interested parties 

the opportunity to file a petition for 

judicial review in the United States 

Court of Appeals for the appropriate 

circuit within 60 days of such 

rulemaking action. Thus, the EPA 

believes judicial review of this action 

under section 307(b)(1) is not available.

Air Plan Approval; Washington; 

Olympic Region Clean Air Agency, 

Recreational Fires 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is approving a revision to 

the Washington State Implementation 

Plan (SIP) that was submitted by the 

Department of Ecology (Ecology) in 

coordination with the Olympic Region 

Clean Air Agency (ORCAA). In 2013, 

Ecology and ORCAA inadvertently 

submitted for incorporation into the SIP 

a ban on small, recreational fires in 

Thurston County. These fires are 

defined as having a maximum pile size 

of three feet in diameter by two feet high 

using seasoned firewood or charcoal, 

generally associated with backyard, 

summer campfires. Ecology and ORCAA 

provided a review of the historical 

record to demonstrate that the ban on 

recreational fires was not relied upon 

for attainment, maintenance, or 

reasonable further progress in the 

Thurston County area. Ecology and 

ORCAA also provided data to 

demonstrate that removing the ban on 

recreational fires would not interfere 

with maintenance of the national 

ambient air quality standards. 

Therefore, we are approving the request 

by Ecology and ORCAA to remove this 

provision from the SIP. 

DATES: This final rule is effective 

February 18, 2025. 

ADDRESSES: The EPA has established a 

docket for this action under Docket ID 

No. EPA–R10–OAR–2024–0430. All 

documents in the docket are listed on

SUPPLEMENTARY INFORMATION: 

Throughout this document, wherever 

‘‘we’’ or ‘‘our’’ is used, it means the 

EPA. 

I. Background 

On October 24, 2024, the EPA 

proposed to approve revisions to the 

Washington SIP to remove a ban on 

small, recreational fires in Thurston 

County (89 FR 84842). The reasons for 

our proposed action are included in the 

proposal and will not be restated here. 

The public comment period closed on 

November 25, 2024. We received two 

comments from members of the public. 

The full text of the comments may be 

found in the docket for this action. We 

have summarized the comments in the 

following section II. of this preamble. 

II. Comments 

The first commenter conveyed overall 

support for our proposed action. The 

EPA acknowledges the commenter’s 

support. 

The second commenter expressed 

concern about air emissions from 

cannabis plants and stated there is a 

need to study volatile organic 

compound (VOC) emissions from the 

plants and how such emissions may 

contribute to ozone formation. This 

comment is outside the scope of this 

action. The revisions to Washington’s 

SIP do not relate to cannabis production 

in general or VOC emissions from 

cannabis production in particular. 

Rather, the revisions to Washington’s 

SIP remove a ban on small, recreational 

fires using seasoned firewood or 

charcoal. In addition, the commenter 

did not indicate that EPA approval of 

the SIP submissions is inconsistent with 

the Clean Air Act. 

Therefore, for the reasons stated in 

this preamble and our proposed action 

on October 24, 2024, we are finalizing 

our action as proposed (89 FR 84842). 

III. Final Action 

The EPA is approving ORCAA 

regulation 6.2.7, State effective March 6, 

2023, and incorporating it by reference 

into the Washington SIP at 40 CFR 

52.2470(c)—Table 6—Additional 

Regulations Approved for the Olympic 

Region Clean Air Agency (ORCAA) 

Jurisdiction. This action repeals a ban 

on recreational fires within the city 

limits of Lacey, Olympia, and 

Tumwater, and unincorporated areas of 

Thurston County lying within or 

between the municipal boundaries of 

these cities. Based on the demonstration 

provided by Ecology and ORCAA, we 

determined that the revision will not 

interfere with maintenance of the 

national ambient air quality standards 

or other applicable requirements of the 

Clean Air Act. 

IV. Incorporation by Reference 

In this document, the EPA is 

finalizing regulatory text that includes 

incorporation by reference. In 

accordance with requirements of 1 CFR 

51.5, we are finalizing the incorporation 

by reference of ORCAA regulation 6.2.7, 

State effective March 6, 2023, as 

described in section III of this preamble 

and set forth in the amendments to 40 

CFR part 52 in this document. The EPA 

has made, and will continue to make, 

these materials generally available 

through https://www.regulations.gov 

and at the EPA Region 10 Office (please 

contact the person identified in the FOR

FURTHER INFORMATION CONTACT section of 

this preamble for more information).
