 beyond the rule’s compliance date, i.e., from July 8, 2027 through July 8, 2029.  Additionally, in June 2025, the EPA proposed to repeal certain aspects of the May 2024 MATS rule including the revised emission limit for filterable particulate matter for which the presidential exemption was granted.  Comments on the proposed rule are due August 2025, and the EPA is expected to finalize the rule by the end of 2025.

Good Neighbor Plan/Cross-State Air Pollution Rule

As discussed in the Form 10-K, in June 2023 the EPA published its final Federal Implementation Plan (FIP), known as the Good Neighbor Plan, to address interstate transport for the 2015 ozone NAAQS which would increase the stringency of the Cross-State Air Pollution Rule (CSAPR) program in all four of the states where the Utility operating companies operate.  The FIP would significantly reduce ozone season nitrogen oxides (NOx) emission allowance budgets and allocations for electric generating units.  Prior to issuance of the FIP, in February 2023 the EPA issued related State Implementation Plan (SIP) disapprovals for many states, including the four states in which the Utility operating companies operate, and these SIP disapprovals are the subject of many legal challenges, including a petition for review filed by Entergy Louisiana challenging the disapproval of Louisiana’s SIP.  Judicial stays of the SIP disapprovals were granted in all four states in which the Utility operating companies operate.  In March 2025 the United States Fifth Circuit Court of Appeals concluded that the EPA properly disapproved Texas’s and Louisiana’s SIPs but found that the EPA’s disapproval was unreasonable for Mississippi’s SIP.  The United States Eighth Circuit Court of Appeals has not issued a merits decision yet in the Arkansas SIP disapproval litigation.  The FIP is also subject to numerous legal challenges in various federal circuit courts of appeals, and in June 2024 the United States Supreme Court issued an order, in challenges filed in the D.C. Circuit, staying enforcement of the FIP pending the D.C. Circuit’s review of the rule.  Following the United States Supreme Court stay, the EPA also stayed the FIP.  In March 2025 the EPA asked the D.C. Circuit for a voluntary remand to reconsider the FIP.  In its declaration, the EPA states that it plans to reconsider, among other things, what states are
