Determination To Defer Sanctions; California; Eastern Kern Air Pollution Control District; Stationary Combustion Turbines
AGENCY:
Environmental Protection Agency (EPA).
ACTION:
Interim final determination.
SUMMARY:
The Environmental Protection Agency (EPA) is making an interim final determination that the California Air Resources Board (CARB) has submitted a rule on behalf of the Eastern Kern Air Pollution Control District (EKAPCD or "District") that addresses deficiencies in its Clean Air Act (CAA or "Act") State Implementation Plan (SIP) concerning emissions of oxides of nitrogen (NO X ) from stationary gas turbines. This determination is based on a proposed approval, published elsewhere in this issue of the Federal Register , of EKAPCD Rule 425 that regulates this category of sources. The effect of this interim final determination is that the application of offset sanctions that was triggered by a previous limited disapproval by the EPA in 2023 is now stayed, and the application of highway sanctions is now deferred. If the EPA finalizes its approval of EKAPCD's submission, relief from these sanctions will become permanent.
DATES:
This interim final determination is effective June 20, 2025. However, comments will be accepted on or before July 21, 2025.

I. Background
On June 15, 2023 (88 FR 39182), the EPA issued a final rule promulgating a limited approval and limited disapproval for the EKAPCD rule listed in Table 1 that was submitted by CARB to the EPA for inclusion into the California SIP ("2023 final rule").
| Rule No. | Rule title | Amended | Submitted | EPA action in 2023 |
|---|---|---|---|---|
| 425 | Stationary Gas Turbines (Oxides of Nitrogen) | 01/13/2018 | 05/23/2018 | Limited Approval and Limited Disapproval. |
Sections 182(b)(2) and 182(f) of the CAA require that SIPs for ozone nonattainment areas classified as "Moderate" or above implement Reasonably Available Control Technology (RACT) for any source covered by a Control Techniques Guidelines document and for any major source of volatile organic compounds or NO X . The EKAPCD must implement RACT-level controls because it regulates the Kern County (Eastern Kern) ozone nonattainment area that is classified as "Moderate" for the 1997 8-hour National Ambient Air Quality Standards (NAAQS), "Severe-15" for the 2008 8-hour NAAQS, and "Serious" for the 2015 8-hour ozone NAAQS. 1

1 ?See 40 CFR 81.305.
In the 2023 final rule, we determined that although the EKAPCD rule strengthened the SIP and was largely consistent with the requirements of the CAA, the submitted rule contained a deficiency that precluded our full approval of the rule into the SIP. The EKAPCD's previously submitted Rule 425 included a revised NO X emission limitation for a single Westinghouse W251B10 combustion turbine, with Authority to Construct permits issued before 1983, of 25 parts per million by volume (ppmv). This revised emission limitation was higher than the limits for comparably sized units elsewhere in the District, and under most operating conditions, higher than the limits applicable to such units in the SIP-approved version of Rule 425 at that time. The EKAPCD did not sufficiently justify why this limit met the RACT requirement or sufficiently explain why this relaxation did not interfere with attainment of the NAAQS, reasonable further progress, or other requirements of the Act.
Pursuant to section 179 of the CAA and our regulations at 40 CFR part 52, the limited disapproval action on Rule 425 under title I, part D, of the Act started a sanctions clock for imposition of offset sanctions under the nonattainment new source review program 18 months after the action's effective date of July 17, 2023, and highway sanctions six months later.
On November 13, 2024, the EKAPCD revised Rule 425, and on December 12, 2024, CARB submitted it to the EPA for approval into the California SIP as shown in Table 2 below.
| Local agency | Rule No. | Rule title | Amended | Submitted |
|---|---|---|---|---|
| EKAPCD | 425 | Stationary Gas Turbines (Oxides of Nitrogen) | 11/13/2024 | 12/12/2024 |
The revised EKAPCD Rule 425 in Table 2 is intended to address the deficiencies identified in our June 15, 2023 final limited disapproval. In the Proposed Rules section of this Federal Register , we have proposed approval of the revised EKAPCD Rule 425. Based on this proposed action approving Rule 425 into the California SIP, we believe that it is more likely than not that the State's submittal now meets the applicable CAA requirements. Therefore, the EPA is making this interim final determination based on our concurrent proposal to approve the State's December 12, 2024 SIP submission to correct the deficiencies identified in the June 15, 2023 disapproval of Rule 425. This interim final determination, effective on publication, stays the application of the offset sanctions and defers the application of highway sanctions that were triggered by our June 15, 2023 final limited disapproval of Rule 425.
While the EPA is not providing an opportunity for public comment before the deferral of CAA section 179 sanctions is effective, the EPA is providing the public with an opportunity to comment on this stay and deferral of sanctions after the fact. In the event the EPA reverses its preliminary determination that the State has corrected the deficiencies (as explained in the proposed approval), sanctions would become effective pursuant to 40 CFR 52.31(d)(2)(i). Additionally, the EPA is providing an opportunity to comment on the concurrent proposed approval that is the basis for this interim final determination, so the public has an opportunity to comment on that action before any sanctions clock could be permanently stopped or any already applied sanctions are permanently terminated. If the EPA finalizes the approval as proposed, then all sanctions and any sanction clocks triggered by our June 15, 2023 final limited approval and limited disapproval would be permanently terminated on the effective date of our final approval of Rule 425.
II. The EPA's Evaluation and Action
We are making an interim final determination to stay and defer CAA section 179 sanctions associated with our limited disapproval action on June 15, 2023, of EKAPCD Rule 425. This determination is based on our concurrent proposal to fully approve EKAPCD Rule 425 which, if finalized, would resolve the deficiencies identified in our limited disapproval that triggered sanctions under section 179 of the CAA.
[top] The basis for allowing such an interim final action stems from section 553(b)(B) of the Administrative Procedures Act (APA) which provides that the notice and opportunity for comment requirements do not apply when the Agency finds that those procedures are "impracticable, unnecessary, or contrary
Section 553(d)(1) of the APA provides that final rules shall not become effective until 30 days after publication in the Federal Register "except . . . a substantive rule which grants or recognizes an exemption or relieves a restriction." The purpose of this provision is to "give affected parties a reasonable time to adjust their behavior before the final rule takes effect."? 2 However, when the agency grants or recognizes an exemption or relieves a restriction, affected parties do not need a reasonable time to adjust because the effect is not adverse. Because this rule relieves a restriction, the EPA finds good cause under 5 U.S.C. 553(d)(1) for this action to become effective on the date of publication of this action.

III. Statutory and Executive Order Reviews
This action defers sanctions and imposes no additional requirements. 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);
• Is not subject to Executive Order 14192 (90 FR 9065, February 6, 2025) because SIP actions are exempt from review under Executive Order 12866;
• 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 proposes to approve 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 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 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).
This action is subject to the Congressional Review Act (CRA), and the EPA will submit a rule report to each House of the Congress and to the Comptroller General of the United States. The CRA 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 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 action as discussed in section II of this preamble, including the basis for that finding.
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 August 19, 2025. Filing a petition for reconsideration by the EPA Administrator of this action does not affect the finality of this action for the purpose of judicial review, nor does it extend the time within which 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 CAA section 307(b)(2)).
