Justices weigh whether the Air Force must study blowing up bombs on a Guam beach
The Supreme Court heard Department of the Air Force v. Prutehi Guåhan (No. 25-579) on Wednesday, among the first arguments of the new term. Since 1982 the Air Force has disposed of old munitions by open burning and detonation at Tarague Beach, near Andersen Air Force Base, a site that sits above the aquifer supplying drinking water to more than 80% of the island. In 2021 it asked Guam regulators to renew its hazardous-waste permit without an environmental review under the National Environmental Policy Act. A Guam nonprofit sued; a federal judge dismissed for lack of standing; the Ninth Circuit revived the case 2–1. The government argues a permit application is not a final agency action that can be challenged, and that following the hazardous-waste law satisfied its duties. The group says the law requires a hard look before, not after. Reports from the courtroom say justices across the spectrum pressed both sides: several worried that ruling for the Air Force would leave the group no way to sue at all, while many also worried that allowing the suit would invite a wave of challenges to agency applications. No clear majority emerged. A decision is expected by June.
The case is formally about procedure, when an agency's paperwork becomes something a court may review, but the stakes are about who gets to question the military in U.S. territories. Guam has no voting representation in Congress and no vote for president; the courts are its main lever. The ruling will also shape how much environmental review the Pentagon owes before it acts anywhere.
Not directly, unless you drink Guam's water. But NEPA governs highways, pipelines and housing projects in every state, and a decision narrowing who may sue over an agency's application would reach all of them.
If every permit application can be litigated before an agency even decides, nothing gets built or defended. The military followed the hazardous-waste law; NEPA was never meant to be a second gate.
The Air Force has been exploding bombs over an island's water supply for forty years without an environmental study. If a renewal is not the moment to ask for one, there is no moment, and that is what the justices seemed to sense.
Listen for the word 'standing' in the transcript when it is posted. The justices' worry about shutting the courthouse door entirely is the more unusual signal here; this Court does not usually lean that way in environmental cases. Expect a narrow ruling on what counts as a final action, not a verdict on the bombs.
