II. Description of Action

On March 15, 2023, the EPA promulgated the Good Neighbor Plan, which established Federal implementation plan (FIP) requirements for sources in 23 States to address “good neighbor” obligations under CAA section 110(a)(2)(D)(i)(I) for the 2015 ozone NAAQS. Following the finalization and publication of the Good Neighbor Plan, several parties filed petitions with the EPA seeking reconsideration and/or an administrative stay of the Good Neighbor Plan, pursuant to either the Administrative Procedure Act, 5 U.S.C. 705, or CAA Act section 307, 42 U.S.C. 7607. Four of these petitions expressly sought reconsideration by the Agency specifically on grounds related to the issuance of partial judicial stay orders of the separate State implementation plan (SIP) disapproval action (88 FR 9336; Feb. 13, 2023) that had been entered as to several of the States covered by the Good Neighbor Plan.

In the denial letters, the EPA explains that it is partially denying these four petitions for reconsideration, because the objections are not “centrally relevant” to the Good Neighbor Plan in the sense that, having considered the two issues raised in relation to the judicial stays, the EPA found they provide no basis on which the Good Neighbor Plan should be modified or withdrawn. The enclosure to the denial letters articulates the rationale for the EPA's final response and is available in the docket for this action.

III. Judicial Review

This final action may be challenged in the United States Court of Appeals for the District of Columbia Circuit. Pursuant to CAA section 307(b)(1), petitions for judicial review of this action must be filed in that court within 60 days after the date notice of this final action is published in the Federal Register .

CAA section 307(b)(1) governs judicial review of final actions by the EPA. This section provides, in part, that petitions for review must be filed in the D.C. Circuit: (1) when the Agency action consists of “nationally applicable regulations promulgated, or final actions taken, by the Administrator,” or (2) when the Agency action is locally or regionally applicable, if “such action is based on a determination of nationwide scope or effect and if in taking such action the Administrator finds and publishes that such action is based on such a determination.” Numerous petitions for review of the Good Neighbor Plan are currently proceeding ( printed page 23527) before the D.C. Circuit. For the same reasons that the D.C. Circuit is the appropriate venue for challenges to the Good Neighbor Plan, it is also the appropriate venue for any challenges to this final action.

This action is “nationally applicable” within the meaning of CAA section 307(b)(1) because it denies petitions to reconsider and stay the Good Neighbor Plan, which is itself a nationally applicable action. 88 FR 36654 at 36860; see also Order, Kentucky Energy and Environment Cabinet v. EPA, No. 23-3605 (6th Cir. Nov. 9, 2023). On its face, the Good Neighbor Plan is nationally applicable because it applies nationally consistent standards and uniform methodologies to 23 States located in ten of the eleven regional Federal judicial circuits across the Nation. 88 FR 36654 at 36860. Although the Good Neighbor Plan is temporarily stayed in 12 States as a result of pending litigation, see notes 4 and 5 supra, these temporary stays do not alter the rule's national applicability.^[3] This denial is likewise nationally applicable because the result of this partial denial of the four petitions identified herein is that the existing Good Neighbor Plan remains in place and undisturbed—and because any judicial order disturbing the EPA's reasoning herein would impact sources, states, and other parties across multiple judicial circuits.

In the alternative, to the extent a court finds this action or a relevant portion thereof to be locally or regionally applicable, the Administrator hereby makes and publishes a finding that the action is based on several determinations of “nationwide scope or effect” within the meaning of CAA section 307(b)(1). These determinations, which lie at the core of this action and are the primary aspects of the Good Neighbor Plan that petitioners ask the EPA to reconsider, include: the determination that the Good Neighbor Plan is lawful and implementable as applied in any individual state even if it is not in effect for any other particular State or group of States; the determination that the Good Neighbor Plan is premised on a series of national-scale analyses that are not limited in scope to any particular geography or group of States; and the determination that the Good Neighbor Plan need not be reconsidered as to any group of sources or States on the basis that publication of the Good Neighbor Plan in the Federal Register occurred following the issuance of preliminary judicial stay orders as to several States.
