Accordingly, that nonattainment designation for the area has been vacated. The vacatur of the nonattainment designation necessarily requires the withdrawal of two contingent actions since the underlying designation is no longer valid: EPA's finding of failure to submit an attainment plan (FFS) issued on August 10, 2020, and EPA's finding of failure to attain the NAAQS by the attainment date (FFA) issued on December 17, 2024. The EPA is withdrawing these two final actions in accordance with the court's decision and finds that any requirements deriving from either the FFS or the FFA are no longer applicable. </SUM> <DATES> <HD SOURCE="HED">DATES:</HD> This final rule is effective September 5, 2025. </DATES> <HD SOURCE="HED">ADDRESSES:</HD> The EPA has established a docket for this action under Docket ID No. EPA-R06-OAR-2022-0311, at <E T="03">https://www.regulations.gov.</E> <E T="03">Docket:</E> The index to the docket for this action is available electronically at <E T="03">https://www.regulations.gov.</E> While all documents in the docket are listed in the index, some information may not be publicly available due to docket file size restrictions or content ( <E T="03">e.g.,</E> Confidential Business Information (CBI)). <FURINF> <HD SOURCE="HED">FOR FURTHER INFORMATION CONTACT:</HD> Andrew Lee, EPA Region 6 Office, Infrastructure and Ozone Section, telephone number: (214) 665-6750, email address: <E T="03">lee.andrew.c@epa.gov.</E> Please call or email the contact listed above if you need alternative access to material indexed but not provided in the docket. </FURINF> <SUPLINF> <HD SOURCE="HED">SUPPLEMENTARY INFORMATION:</HD> Throughout this document “we,” “us,” and “our” means the EPA. <HD SOURCE="HD1">I. Background</HD> On June 22, 2010, the EPA published a new 1-hour primary SO <E T="52">2</E> NAAQS of 75 parts per billion (ppb). <SU>1</SU> <FTREF/> Subsequently, the EPA designated portions of Rusk and Panola Counties, Texas as nonattainment for this 2010 1-hour primary SO <E T="52">2</E> NAAQS, effective January 12, 2017. <SU>2</SU> <FTREF/> The primary major source of emissions in the area is the Martin Lake Steam Electric Station (Martin Lake), a coal-fired power plant owned by Luminant Generation Company LLC (Luminant), a subsidiary of Vistra Energy Corporation (Vistra). Under section 191 of the Clean Air Act (CAA), Texas was required to submit an SO <E T="52">2</E> attainment plan to the EPA within 18 months of the effective date of the nonattainment designation, <E T="03">i.e.,</E> by no later than July 12, 2018, for the Rusk-Panola area. Under CAA section 179(c)(1), the EPA was required to determine whether the nonattainment area had attained the NAAQS by the applicable attainment date, in this case, January 12, 2022. <FTNT> <SU>1</SU>   <E T="03">See</E> 75 FR 35520. <E T="03">See also</E> 40 CFR 50.17(a)-(b). </FTNT> <FTNT> <SU>2</SU>   <E T="03">See</E> 81 FR 89870 <E T="03">See also</E> 40 CFR part 81, subpart C. </FTNT> On August 10, 2020, the EPA published “Findings of Failure to Submit State Implementation Plans Required for Attainment of the 2010 1-Hour Primary Sulfur Dioxide (SO <E T="52">2</E> ) National Ambient Air Quality Standard (NAAQS)” addressing requirements for three SO <E T="52">2</E> nonattainment areas, including the finding that Texas failed to submit the required SIP for the Rusk Panola nonattainment area by the July 12, 2018 CAA deadline. <SU>3</SU> <FTREF/> This finding, effective on September 9, 2020, triggered sanction clocks and the CAA section 110(c) requirement for the EPA to promulgate a federal implementation plan (FIP) for the area within two years of the finding (September 9, 2022) unless the state submitted and obtained EPA approval of a SIP revision correcting the deficiency. On February 28, 2022, the Texas Commission on Environmental Quality (TCEQ) submitted an attainment plan SIP for the Rusk Panola area. On August 24, 2022, the EPA determined that the submittal was complete under 40 CFR part 51, appendix V, which stopped the mandatory emissions offsets sanctions that were in effect and the 24-month sanction clock for the imposition of highway funding sanctions. <SU>4</SU> <FTREF/> However, this completeness determination did not eliminate the EPA's FIP obligation required by the FFS. <FTNT> <SU>3</SU>   <E T="03">See</E> 85 FR 48111; this document also addressed another 2010 SO <E T="52">2</E> nonattainment area. </FTNT> <FTNT> <SU>4</SU>   Completeness Determination Letter from David Garcia, Air and Radiation Division Director—EPA Region 6 to Jon Niermann, Chairman, TCEQ, (August 24, 2022), available in the docket for this action. </FTNT> On December 17, 2024, the EPA published a “Finding of Failure To Attain the Primary 2010 One-Hour Sulfur Dioxide Standard” determining that Texas failed to attain the NAAQS for the Rusk Panola area by the January 12, 2022, CAA deadline. Under CAA section 179(d)(2), following a Finding of Failure to Attain, the responsible air agency has up to 12 months from the effective date of the determination to submit a revised SIP for the area demonstrating attainment. According to CAA section 179(d)(3), this revised SIP is to achieve attainment of the one-hour SO <E T="52">2</E> NAAQS as expeditiously as practicable, but no later than 5 years from the effective date of the area's failure to attain. <HD SOURCE="HD1">II. Rationale for Withdrawals of the Finding of Failure To Submit and Finding of Failure To Attain for the Rusk Panola Area</HD> Following the January 12, 2017, nonattainment designation of the Rusk Panola area, the State of Texas and industry petitioners (collectively, Petitioners) filed Petitions for Review challenging EPA's final action. The Fifth Circuit initially denied the petitions for review and upheld the nonattainment designation on January 11, 2024. <E T="03">Texas</E> v. <E T="03">EPA,</E> 91 F.4th 280 (5th Cir. 2024), <E T="03">vacated by,</E> 137 F.4th 353 (5th Cir. 2025). Subsequently, Petitioners filed a petition for rehearing en banc. On May 16, 2025, the Court, in a panel rehearing, issued a revised opinion granting the petitions for review. <E T="03">Texas</E> v. <E T="03">EPA,</E> 137 F.4th 353 (5th Cir. 2025). The Court's mandate took effect on July 8, 2025, which vacated the nonattainment designation for the Rusk Panola area and remanded the designation of the area “. . . for EPA to consider the data that is available now . . . .” <E T="03">Id.</E> at 375. As a result of the court's decision in <E T="03">Texas</E> v. <E T="03">EPA,</E> the Rusk Panola area no longer retains a nonattainment designation and therefore the EPA is withdrawing the August 2020 FFS and December 2024 FFA. The August 2020 FFS was required under CAA section 179(a)(1) where the EPA “. . .finds that a state failed, for an area designated as nonattainment. . . to submit a plan . . .”. However, this finding is no longer appropriate in light of the court's decision. The December 2024 FFA was required under CAA section 179(c) where the EPA must determine whether a nonattainment area has attained the NAAQS by the relevant attainment date. However, this finding is also no longer appropriate following the court's vacatur of the designation. Pursuant to the court's decision, the FFS for Rusk Panola must be withdrawn and the FFA for Rusk Panola must be withdrawn and removed from the Code of Federal Regulations (CFR). <HD SOURCE="HD1">III. Final Action</HD> In accordance with the court's decision in <E T="03">Texas</E> v. <E T="03">EPA,</E> the EPA is withdrawing the August 2020 finding that Texas failed to submit an attainment plan SIP for the Rusk Panola area. EPA is also withdrawing the December 2024 finding that the Rusk Panola area failed to attain the NAAQS by its applicable CAA attainment date. This action does not impact the other areas addressed in the August 2020 FFS action. The requirements for the EPA to impose sanctions under CAA sections 179(a) and (b) and promulgate a FIP under CAA section 110(c) following an effective FFS are no longer applicable. The CAA requirement for Texas to submit a revised SIP for the Rusk Panola area demonstrating attainment under 179(d)(2) and the requirement for the Rusk Panola area to attain under an updated attainment date under 179(d)(3) following an effective FFA are no longer applicable. The EPA is taking this action as a final rule without providing an opportunity for public comment or a public hearing because the EPA finds that the Administrative Procedure Act (APA) good cause exemption applies. In general, the APA requires that general notice of proposed rulemaking shall be published in the <E T="04">Federal Register</E> . Such notice must provide an opportunity for public participation in the rulemaking process. However, the APA does provide an avenue for an agency to directly issue a final rulemaking in certain specific instances. This may occur when an agency for good cause finds (and incorporates th ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Preview showing 10k of 17k characters.
