Regulation of the Nuclear Power Industry

The following is an update to the “Regulation of the Nuclear Power Industry” section of Part I, Item 1 of the Form 10-K.

Nuclear Waste Policy Act of 1982

Nuclear Plant Decommissioning

In March 2025 filings with the NRC were made that reported the decommissioning funding for all of Entergy’s subsidiaries’ nuclear plants. Those reports showed that decommissioning funding for each of the nuclear plants met the NRC’s financial assurance requirements.

Environmental Regulation

The following are updates to the “Environmental Regulation” section of Part I, Item 1 of the Form 10-K.

In March 2025 the EPA announced a series of deregulatory actions, including reconsideration of the Mercury and Air Toxics Standard rule, reconsideration of greenhouse gas emissions rules, evaluation of whether to extend the compliance deadlines under the 2024 coal combustion residuals rule, and reconsideration of the effluent limitations guidelines. Entergy continues to monitor the EPA’s reconsideration efforts.

National Ambient Air Quality Standards

See the Form 10-K for discussion of the National Ambient Air Quality Standards (NAAQS) set by the EPA in accordance with the Clean Air Act. The following is an update to that discussion.

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 subject to the FIP. In April 2025 the D.C. Circuit held the cases in abeyance pending further order of the court. The EPA anticipates a new rule by fall 2026. Entergy is monitoring this litigation, any subsequent rulemaking, and assessing its compliance options in the event that the FIP becomes effective.
