Supreme Court hears Guam hazardous-waste review dispute
The case asks when a federal permit application becomes reviewable and whether a separate environmental review must occur first.
A procedural dispute with environmental consequences
The Supreme Court heard argument Wednesday in Department of the Air Force v. Prutehi Guahan, a case arising from a hazardous-waste permit renewal in Guam. The dispute concerns when courts may review a federal agency’s permit application and whether a separate federal environmental review must occur before the application is submitted.
The case involves the Resource Conservation and Recovery Act, known as RCRA, which regulates hazardous waste from generation through treatment and disposal. The Environmental Protection Agency may authorize state and territorial regulators to run permitting programs, including for facilities operated by the federal government.
The justices are reviewing a Ninth Circuit decision. Their ruling could affect the sequence of federal environmental analysis and judicial review, but the case does not ask the Court to issue or deny the underlying Guam permit itself.
Two questions before the Court
The first question is whether the federal government’s submission of an application to renew a RCRA permit is “final agency action” that can be reviewed immediately under the Administrative Procedure Act. Courts ordinarily use finality requirements to separate completed agency decisions from preliminary steps.
The second question is whether the federal government must complete the general environmental-review procedures of the National Environmental Policy Act, or NEPA, before submitting the renewal application. RCRA has its own procedures for considering environmental effects within hazardous-waste permitting.
The Air Force argues that submitting an application is not the last word because the territorial regulator must still review it and may require changes. Prutehi Guahan, an environmental organization formerly known as Prutehi Litekyan, maintains that the federal submission reflects a consequential agency decision and that environmental review cannot simply be postponed.
What comes next
The hearing list allotted one hour for argument. Sopan Joshi of the Justice Department appeared for the federal petitioners, and Caroline Flynn appeared for the respondent. The docket includes the parties’ merits briefs and filings from outside groups and governments presenting additional views.
Questions from justices during argument test legal theories and do not establish the eventual vote. The Court generally posts same-day audio and transcripts, which provide the most direct public record of the exchange.
A written decision is expected later in the term. The Court could resolve both questions, decide one and avoid the other, or issue a narrower ruling tied to the procedural posture of this permit renewal.
For federal facilities operating under state or territorial environmental programs, the practical issue is timing: when an application becomes reviewable, what analysis must accompany it and how much work remains for the permitting authority. The answer may shape litigation over other federal permit renewals without deciding the substantive environmental standard for every facility.
