SUPPLEMENTARY INFORMATION: 

Throughout this document whenever 

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

EPA. 

I. Background Information 

On June 22, 2010 (75 FR 35520), EPA 

revised the primary SO2 NAAQS, 

establishing a new health-based 1-hour 

standard of 75 parts per billion (ppb). 

EPA promulgated designations for this 

standard in four rounds. On September 

18, 2015, Illinois submitted its 

recommendations to EPA to designate 

certain areas of the state as part of the 

Round 2 designations. Illinois 

recommended a portion of southern 

Alton Township in Madison County be 

designated as nonattainment for the 

2010 SO2 NAAQS. EPA concurred with 

Illinois’ analysis and published a final 

action designating the area as 

nonattainment for the 2010 SO2 NAAQS 

effective September 12, 2016 (81 FR 

45039). 

Illinois submitted an attainment plan 

for the Alton Township nonattainment 

area on December 3, 2018. The plan 

included computer modeling that 

included emissions from the Alton Steel 

Inc. (Alton Steel) facility in Alton, 

Illinois, and emissions from the Ameren 

Missouri-Sioux Energy Center (AmerenSioux) power plant in Missouri, located 

about 13 kilometers west-northwest of 

the nonattainment area. On March 14, 

2019, the Illinois Environmental 

Protection Agency issued Construction 

Permit #18020009 for the Alton Steel 

facility to operate a new ladle 

metallurgy facility (LMF) stack and to 

remove the downfacing vents that were 

contributing to modeled nonattainment 

at the facility. EPA included additional 

dispersion modeling to supplement 

Illinois’ attainment demonstration to 

demonstrate that the emission limits 

required by the Illinois SIP and 

submitted for EPA approval provide for 

modeled concentrations meeting the 

2010 SO2 NAAQS. EPA approved 

Illinois’ attainment plan revision on 

February 21, 2023 (88 FR 10464). 

On October 2, 2023, Illinois submitted 

a redesignation request and 

maintenance plan for the Alton 

Township nonattainment area for the 

2010 SO2 NAAQS. The submitted 

redesignation request and maintenance 

plan includes the Construction Permit 

issued to Alton Steel and the Consent 

Agreement for Ameren-Sioux that has 

been approved into the Missouri SIP (87 

FR 68634, November 16, 2022) with 

accepted SO2 emissions limits. On 

October 8, 2024 (89 FR 81409), EPA 

proposed to approve the redesignation 

of the Alton Township area in Madison 

County, Illinois from nonattainment to 

attainment for the 2010 SO2 NAAQS in 

accordance with Illinois’ request 

submitted on October 2, 2023. EPA has 

determined the area is attaining the 

2010 SO2 NAAQS and that the 

improvement in air quality is due to 

permanent and enforceable SO2

emission reductions in the area. EPA is 

also approving Illinois’ maintenance 

plan, which is designed to ensure that 

the area will continue to maintain 

attainment of the 2010 SO2 NAAQS. 

Additionally, under section 179(c) of 

the CAA, EPA is required to determine 

whether a nonattainment area attained a 

standard by the applicable attainment 

date based on the area’s air quality as of 

the attainment date. In this action, EPA 

is determining that the Alton Township 

area did attain the 2010 SO2 NAAQS by 

the attainment date of September 12, 

2021. An explanation of the CAA 

requirements, a detailed analysis of the 

revisions, and EPA’s reasons for 

proposing approval were provided in 

the notice of proposed rulemaking 

(NPRM) and will not be restated here. 

The public comment period for this 

proposed rule ended on November 7, 

2024. EPA received no comments on the 

proposal. Therefore, we are finalizing 

our action as proposed. 

II. Final Action 

EPA is approving the redesignation of 

the Alton Township area from 

nonattainment to attainment, meeting 

the criteria under CAA section 

107(d)(3)(E) for the 2010 SO2 NAAQS in 

accordance with Illinois’ October 2, 

2023, request. EPA is determining that 

the area is attaining the 2010 SO2

NAAQS and that the improvement in air 

quality is due to permanent and 

enforceable SO2 emission reductions in 

the area. On this basis, EPA is approving 

the redesignation request from Illinois 

for the area and changing the legal 

designation of the Alton Township area 

in Madison County at 40 CFR part 81 to 

attainment for the 2010 SO2 NAAQS. 

EPA is also approving Illinois’ 

maintenance plan under CAA section 

175A. The maintenance plan 

demonstrates that the area will continue 

to maintain the 2010 SO2 NAAQS and 

includes a process to develop 

contingency measures to remedy any 

future violations of the 2010 SO2

NAAQS and procedures for evaluation 

of potential violations. This includes 

Illinois’ commitment to provide EPA 

with an annual emissions report of the 

newly constructed Alton Steel LMF 

stack as part of Illinois’ annual network 

plan submittal to provide ongoing 

verification of attainment. 

Finally, EPA is determining that the 

Alton Township area attained the 2010 

SO2 NAAQS by the September 12, 2021, 

attainment date addressing EPA’s 

obligation under CAA section 179(c). 

III. Statutory and Executive Order 

Reviews 

Under the 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, 

EPA’s role is to approve state choices, 

provided that they meet the criteria of 

the CAA. Accordingly, this action 

merely approves state law as meeting 

Federal requirements and does not 

impose additional requirements beyond 

those 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, 


ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 89, No. 249 / Monday, December 30, 2024 / Rules and Regulations 106359 

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 approves a state program; 

• 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 CAA. 

In addition, the SIP is not approved 

to apply on any Indian reservation land 

or in any other area where 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 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 E.O. 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 Illinois Environmental Protection 

Agency did not evaluate EJ 

considerations as part of its SIP 

submittal; the CAA and applicable 

implementing regulations neither 

prohibit nor require such an evaluation. 

EPA performed an EJ analysis, as is 

described in the proposed action 

(October 8, 2024, 89 FR 81409) in the 

section titled, ‘‘EJ Considerations.’’ The 

analysis was done for the purpose of 

providing additional context and 

information about this rulemaking to the 

public, not as a basis of the action. Due 

to the nature of the action being taken 

here, this action is expected to have a 

neutral to positive impact on the air 

quality of the affected area. In addition, 

there is no information in the record 

upon which this decision is based 

inconsistent with the stated goal of E.O. 

12898/14096 of achieving EJ for 

communities with EJ concerns. 

This action is subject to the 

Congressional Review Act, and EPA will 

submit a rule report to each House of 

the Congress and to the Comptroller 

General of the United States. This action 

is not a ‘‘major rule’’ as defined by 5 

U.S.C. 804(2). 

Under section 307(b)(1) of the CAA, 

petitions for judicial review of this 

action must be filed in the United States 

Court of Appeals for the appropriate 

circuit by February 28, 2025. Filing a 

petition for reconsideration by the 

Administrator of this final rule does not 

affect the finality of this action for the 

purposes of judicial review nor does it 

extend the time within which a petition 

for judicial review may be filed, and 

shall not postpone the effectiveness of 

such rule or action. This action may not 

be challenged later in proceedings to 

enforce its requirements. (See section 

307(b)(2).)

SUPPLEMENTARY INFORMATION: 

Throughout this document whenever 

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

EPA. 

I. Background 

On June 11, 2024, Ohio EPA 

submitted revisions to Ohio 

Administrative Code (OAC) chapters 

3745–77–01, 3745–77–08, and 3745–77– 

09 to EPA for approval as a title V 

program revision. These revisions were 

made as part of Ohio’s statutory fiveyear regulatory review process and 

include a change to the definition of 

hazardous air pollutant, additional 

requirements pertaining to a permit 

statement of basis and response to 

comments, a reordering of the 

definitions in OAC 3745–77–01, minor 

grammatical changes, and updates to 

test method, publication, and reference 

materials. 

II. What action is EPA taking? 

EPA is approving this submittal as 

part of Ohio’s title V permit program. 

The revisions to Ohio’s rules are 

consistent with 40 CFR part 70 and the 

Clean Air Act (CAA) as discussed 

below. 

The definitions in OAC 3745–77–01 

are reorganized such that the terms are 

listed and group in paragraphs 

alphabetically. These revisions do not 

substantively change the provisions of 

this chapter but provide for easier 

search of and subsequent updates to the 

listed definitions. 

The definition of ‘‘hazardous air 

pollutant’’ in OAC 3745–77–01(H) has 

been revised to include ‘‘. . . as revised 

under 40 CFR part 63, subpart C.’’ This 

change to the definition allows for the 

inclusion of 1-bromopropane, which 

EPA added to the CAA’s list of 


ddrumheller on DSK120RN23PROD with RULES1
