Air Plan Approval; California; Revised Format for Materials Incorporated by Reference
The Environmental Protection Agency (EPA) is revising the format for materials submitted by the State of California that are incorporated by reference into the California State ...
The Environmental Protection Agency (EPA) is revising the format for materials submitted by the State of California that are incorporated by reference into the California State Implementation Plan (SIP). The regulations and other materials affected by this format change have all been previously submitted by the State of California and approved by the EPA. This format revision will primarily affect the “Identification of plan—in part” sections, as well as the format of the SIP materials that will be available for public inspection at the EPA Regional Office and the National Archives and Records Administration (NARA). This action, which only relates to source-specific requirements and certain local and regional California air district rules, is the fourth of a series of actions intended to change the format for the entire California SIP.
DATES:
This rule is effective on August 21, 2025.
ADDRESSES:
The EPA has established a docket for this action under Docket ID No. EPA-R09-OAR-2024-0527. SIP materials which are incorporated by reference into 40 CFR part 52 are available for inspection by appointment at Environmental Protection Agency, Region IX, 75 Hawthorne Street, San Francisco, CA 94105-3901.

I. Background
A. Description of a SIP
Each State has a SIP containing, among other things, 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.
B. How the EPA Enforces SIPs
Each State must formally adopt the control measures and strategies to attain and maintain the NAAQS after the public has had an opportunity to comment on them. They are then submitted to the EPA as requested SIP revisions upon which the EPA must formally act. Once these control measures and strategies are approved by the EPA, after notice and comment rulemaking, they are incorporated into the federally approved SIP and are identified in part 52 (Approval and Promulgation of Implementation Plans), title 40 of the Code of Federal Regulations (40 CFR part 52). The EPA uses the process of incorporation by reference (IBR) to incorporate material into the CFR by referencing the original document(s) without publishing the full text of the material. The actual State regulations approved by the EPA are not reproduced in their entirety in 40 CFR part 52 but are “incorporated by reference,” which means that the EPA has approved a given State regulation with a specific effective date. This format allows both the EPA and the public to know which measures are contained in a given SIP and to help determine whether the State is enforcing the regulations. This format also assists the EPA and the public in taking enforcement action, should a State not enforce its SIP-approved regulations.
C. How the State and the EPA Update the SIP
The SIP is a dynamic document, which the State can revise as necessary to address the unique air pollution problems in the State. Therefore, the EPA must periodically take action on State SIP revisions containing new and/or revised regulations and other materials in order to make them part of the federally-approved SIP. 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 submissions are available for viewing on
https://www.regulations.gov.
On May 22, 1997 (62 FR 27968), the EPA revised the formatting procedures for incorporating by reference federally-approved SIP revisions, as a result of consultations between the EPA and the Office of the Federal Register. These procedures include: (1) a revised SIP document for each State that would use the IBR process under the provisions of title 1 CFR part 51; (2) a revised mechanism for announcing the EPA's approval of revisions to an applicable SIP and updating both the document that has gone through the IBR process and the CFR; and (3) a revised format of the “Identification of Plan” sections for each applicable subpart in 40 CFR part 52 to reflect these revised IBR procedures. The description of the revised SIP document, IBR procedures, and “Identification of plan” format are discussed in further detail in the May 22, 1997
Federal Register
document. We have taken action to revise the format for many State SIPs,
see, e.g.,40 CFR 52.1470 and 52.1490 (“Identification of plan” and “Original identification of plan” sections for the State of Nevada SIP), and take a fourth step today toward revising the format of the California SIP.
D. How the EPA Compiles the SIPs
Under the revised SIP format, the federally-approved regulations, source-specific requirements, and nonregulatory provisions (entirely or portions of) submitted by each State agency have been compiled by the EPA into a “SIP compilation.” The SIP compilation contains the regulations, source-specific requirements, and nonregulatory and quasi-regulatory provisions approved by the EPA through previous rulemaking actions published in the
Federal Register
.
E. How the EPA Organizes the SIP Compilation
Each compilation contains three parts. Part one contains the regulations, part
( printed page 40897)
two contains the source-specific requirements, and part three contains the nonregulatory and quasi-regulatory provisions that have been approved by EPA as part of the SIP. Each part consists of a table or tables of identifying information for each SIP-approved regulation, each SIP-approved source-specific requirement, and each nonregulatory or quasi-regulatory SIP provision. The EPA Regional Offices have the primary responsibility for updating the compilations and ensuring their accuracy.
F. Where You Can Find a Copy of the SIP Compilation
EPA Region IX has developed and will maintain the SIP compilation for California. A copy of the full text of California's regulatory and source-specific SIP compilation will also be maintained at NARA.
G. The Format of the California Identification of Plan Sections
Given the size of the California SIP, the EPA is revising the format of the California SIP in a phased manner. On May 26, 2016 (81 FR 33397), the EPA took the first action to revise the format of the “Identification of plan” section in subpart F in accordance with the revised format described in Section I.C. of this document. Through the first action, we revised the heading of § 52.220 to read “Identification of plan—in part” and added an introductory paragraph to convey our division of the California “Identification of plan” section into two sections:
Amended § 52.220 (renamed “Identification of plan—in part”), which would continue for the time being to function as it has in the past to list past and newly-approved air district rules, local ordinances, source-specific requirements, and nonregulatory and quasi-regulatory provisions and which lists State statutes and State regulations approved on or prior to April 1, 2016; and
New § 52.220a (“Identification of plan—in part”), which lists the State statutes and State regulations approved as part of the California SIP as of April 1, 2016, using the new table format.
This meant that subsequent EPA approvals of air district rules, local ordinances, source-specific requirements, and nonregulatory and quasi-regulatory provisions would continue to be promulgated in 40 CFR 52.220 using the paragraph format whereas subsequent EPA approvals of State statutes and State regulations would be promulgated in 40 CFR 52.220a using the table format. In preparation for future actions to revise the format of the remaining portions of the California SIP, the May 26, 2016 action also organized 40 CFR 52.220a into five paragraphs: (a) Purpose and scope; (b) Incorporation by reference; (c) EPA-approved regulations; (d) EPA-approved source-specific requirements; and (e) EPA-approved nonregulatory provisions and quasi-regulatory measures. “Nonregulatory provisions and quasi-regulatory measures” refers to items such as transportation control measures, certain nonregulatory statutory provisions, control strategies, and monitoring networks.
Our phased approach to converting the format of the California SIP anticipated that, over time, as the EPA completes further rulemaking actions to convert the format of the California SIP, § 52.220a would include a growing number of air district rules, local ordinances, source-specific requirements, and nonregulatory and quasi-regulatory provisions. Once the conversion process is completed, the EPA will redesignate § 52.220a as § 52.220 and rename it simply “Identification of plan.” At that point, all subsequent actions by the EPA to approve California SIP revisions will be promulgated using the new table format. The revised format does not affect Federal enforceability of the SIP and is consistent with the requirements of section 110(h)(1) of the Clean Air Act (CAA) concerning comprehensive SIP publication.
On June 4, 2025 (90 FR 23618), the EPA took a second action to revise the format of the California SIP by converting the format for local ordinances and air district rules approved on or prior to April 17, 2025, for the following air districts: Amador Air District, Antelope Valley Air Quality Management District (AQMD), Bay Area AQMD, Butte County AQMD, Calaveras County Air Pollution Control District (APCD), Colusa County APCD, Eastern Kern APCD, and El Dorado County AQMD. A third action was taken on July 7, 2025, (90 FR 29934) that converted the format for the nonregulatory provisions and quasi-regulatory measures portion of the California SIP.
In this fourth action to revise the format of the California SIP, we are converting the format and publishing the tables listing EPA-approved source-specific requirements as well as EPA-approved rules adopted by the following 21 California air districts: Feather River AQMD, Glenn County APCD, Great Basin Unified APCD, Imperial County APCD, Lake County AQMD, Lassen County APCD, Mariposa County APCD, Mendocino County AQMD, Modoc County APCD, Monterey Bay Air Resources District, North Coast Unified AQMD, Northern Sierra AQMD, Northern Sonoma County APCD, San Diego County APCD, San Luis Obispo County APCD, Santa Barbara County APCD, Shasta County AQMD, Siskiyou County APCD, Tehama County APCD, Tuolumne County APCD, and Yolo-Solano County AQMD. This format revision involves materials approved on or before June 30, 2025, that are part of the current applicable SIP. All subsequent actions by the EPA to approve California SIP revisions related to source-specific requirements or these 21 air districts will be promulgated in 40 CFR 52.220a, paragraph (c) using the new table format. EPA approvals of rules from Mojave Desert AQMD, Placer County APCD, Sacramento Metropolitan AQMD, San Joaquin Valley Unified APCD, South Coast AQMD, and Ventura County APCD will continue to be promulgated in 40 CFR 52.220 using the paragraph format. The format for portions of the California SIP related to rules from these remaining air districts will be revised in future rulemaking actions.
H. When a SIP Revision Becomes Federally Enforceable
All revisions to the applicable SIP become federally enforceable as of the effective date of the revision to the applicable “Identification of plan” or “Identification of plan—in part” section found in each subpart of 40 CFR part 52. All future revisions to the relevant portion of the applicable SIP being converted to the new table format in this action become federally enforceable as of the effective date of the revisions to paragraph (c) or (d) of § 52.220a, in subpart F of 40 CFR part 52.
I. The Historical Record of SIP Revision Approvals
To facilitate enforcement of previously approved SIP provisions and provide a smooth transition to the new SIP processing system, the EPA will retain the “Identification of plan—in part” section for California appearing in 40 CFR 52.220 until the conversion process is completed. After the conversion of the entire California SIP is completed, the “Identification of plan—in part” section will be moved to 40 CFR 52.250 and renamed “Original identification of plan.” After an initial one or two-year period, the EPA will review its experience with the new SIP processing system and decide whether to retain the “Original identification of plan” section for some further period.
( printed page 40898)
II. What the EPA Is Doing in This Action
In this action, the EPA is revising the format for portions of the applicable California SIP related to source-specific requirements and the rules from the following 21 air districts: Feather River AQMD, Glenn County APCD, Great Basin Unified APCD, Imperial County APCD, Lake County AQMD, Lassen County APCD, Mariposa County APCD, Mendocino County AQMD, Modoc County APCD, Monterey Bay Air Resources District, North Coast Unified AQMD, Northern Sierra AQMD, Northern Sonoma County APCD, San Diego County APCD, San Luis Obispo County APCD, Santa Barbara County APCD, Shasta County AQMD, Siskiyou County APCD, Tehama County APCD, Tuolumne County APCD, Yolo-Solano County AQMD. This format revision involves materials approved on or before June 30, 2025, that are part of the current applicable SIP.
This action constitutes a “housekeeping” exercise to ensure that all EPA-approved revisions to the State programs that have occurred are accurately reflected in 40 CFR part 52. The requirements that apply to States and that relate to SIPs and SIP revisions are set forth in the Clean Air Act and in the EPA's regulations at 40 CFR part 51. When the EPA receives a formal SIP revision request, the Agency must publish the proposed revision in the
Federal Register
and provide for public comment before approval.
The EPA has determined that this rule falls under the “good cause” exemption in section 553(b)(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 a rule effective immediately, thereby avoiding the 30-day delayed effective date otherwise provided for in the APA. This action simply reformats and recodifies provisions that are already in effect as a matter of law in Federal and approved State programs. Under section 553 of the APA, an agency may find good cause where notice and public procedure are “impractical, unnecessary, or contrary to the public interest.” Public comment is “unnecessary” and “contrary to the public interest” for this action because the EPA is merely reformatting and recodifying existing law. Immediate notice in the CFR benefits the public by removing outdated citations and making the IBR format clearer and more user-friendly.
III. Incorporation by Reference
In this rule, the EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is reformatting the materials incorporated by reference in previous rulemakings on submittals of the California SIP and SIP revisions, as described in section II of this preamble. The EPA has made, and will continue to make, these documents generally available through
www.regulations.gov
and at the appropriate EPA office (see the
ADDRESSES
section of this preamble for more information).
IV. Statutory and Executive Order Reviews
A. General Requirements
This action does not impose additional requirements beyond those previously approved into the SIP and already 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 underExecutive Order 12866 (58 FR 51735, October 4, 1993);
Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501et 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. 601et 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);
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 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 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).
B. Submission to Congress and the Comptroller General
The Congressional Review Act (5 U.S.C. 801et 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. Section 808 allows the issuing agency to make a rule effective sooner than otherwise provided by the CRA if the agency makes a good cause finding that notice and public procedure is impracticable, unnecessary or contrary to the public interest. This action simply reformats and recodifies provisions that are already in effect as a matter of law in Federal and approved State programs. 5 U.S.C. 802(2). As stated previously, the EPA has made such a good cause finding, including the basis for that finding, and established an effective date of August 21, 2025. The EPA will submit a report containing this rule 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
. This action is not a “major rule” as defined by 5 U.S.C. 804(2).
C. Petitions for Judicial Review
The EPA has also determined that the provisions of section 307(b)(1) of the CAA pertaining to petitions for judicial review are not applicable to this action. Prior EPA rulemaking actions for each individual component of the California SIP compilation had 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.
