The U.S. Supreme Court recently engaged in an intricate legal debate over a lawsuit challenging the U.S. Air Force’s request to renew a permit for detonating hazardous munitions on Guam’s Tarague Beach. This request was brought forth by the oral arguments in the case and detailed in the proceedings of Department of the Air Force v. Prutehi Guåhan. The central question was whether the Air Force’s permit renewal application represents a “final agency action” that can be judicially reviewed at this stage.
Two pivotal statutes intersect in this case: the Resource Conservation and Recovery Act of 1976 (RCRA) and the National Environmental Policy Act of 1969 (NEPA). NEPA mandates an environmental impact review, while RCRA allows the Guam EPA to regulate hazardous waste, revealing a tension between federal and territorial regulatory frameworks.
The litigation arose in 2022 when Prutehi Guåhan claimed the Air Force bypassed NEPA requirements in their permit renewal application. A lower federal court originally dismissed the case, ruling that the Guam EPA’s pending decision precluded finality, rendering the challenge premature. However, the Ninth Circuit Court reversed this decision, prompting the Air Force’s appeal to the Supreme Court.
Arguing for the Air Force, Sopan Joshi of the U.S. Solicitor General’s office contended that a permit application does not constitute a final action, highlighting that RCRA’s permitting process is exhaustive and inherently non-final until an outcome is reached. On the other side, Caroline Flynn, advocating for Prutehi Guåhan, argued NEPA’s role as an “umbrella law” and that a comprehensive environmental analysis should precede further procedural steps.
Justices expressed varied concerns over procedural finality and potential litigation outcomes. Justice Clarence Thomas pondered whether the Air Force’s procedural position—seeking EPA permission—could be considered final. Simultaneously, Justice Ketanji Brown Jackson raised the issue of the proposal’s fluidity, suggesting its non-final status until Guam EPA renders a verdict.
While some justices indicated that NEPA and RCRA could be reconciled without one statute trumping the other, opinions differed on how their interplay affects judicial review. Justice Amy Coney Barrett flagged concerns about judicial review’s scope potentially opening “floodgates” to similar challenges for agency applications. Justice Sonia Sotomayor appeared cautious about consequences reversing earlier procedural work.
A decisive ruling is anticipated in this matter next year, which could have substantial implications for federal and territorial environmental regulatory frameworks, with a particular focus on how interim agency actions can be challenged in court.
