The U.S. Supreme Court on Oct. 7 heard oral arguments in Department of the Air Force v. Prutehi Guahan, a case examining whether the Air Force must conduct an environmental review before detonating expired munitions at a base in Guam. The dispute centers on a 2021 permit renewal application filed by the Air Force to continue the practice of exploding unexploded ordnance, including munitions dating back to World War II, at Andersen Air Force Base on Guam’s northeastern coast.
The case raises questions about the scope of federal environmental laws, including the National Environmental Policy Act (NEPA) and the Resource Conservation and Recovery Act (RCRA), and whether the Air Force’s permit application constitutes a final agency action subject to judicial review. Environmental groups argue that detonations could pollute fragile ecosystems and disrupt local habitats, while the government contends that the permit process is ongoing and not yet finalized.
Core Legal Arguments
During arguments, Assistant to the Solicitor General Sopan Joshi argued that the Air Force’s permit application is not a final agency action under federal law. Joshi stated that treating an application as final would lead to multiple lawsuits during the permitting process, undermining the purpose of the finality requirement. He further asserted that RCRA already specifies when environmental reviews must occur, making additional NEPA requirements duplicative. Joshi suggested that if the court rules the application is not final, it could resolve the case without addressing the broader legal conflict between NEPA and RCRA.
Challenges to Government’s Position
Chief Justice John Roberts questioned the government’s theory, asking how it would allow judicial review if the Air Force’s decision could not be challenged at any stage. The justices also pressed Joshi on whether the government’s interpretation would effectively prevent any legal challenge to the Air Force’s actions, even after a permit is granted. Environmental advocates argue that the practice of detonating munitions poses immediate risks to Guam’s environment and public health, while the Air Force maintains that the process is necessary for safety and compliance with military protocols.
Background and Broader Implications
The dispute began after environmental groups, including Prutehi Guahan, filed a lawsuit challenging the Air Force’s permit renewal. The groups contend that the detonations violate federal environmental laws and threaten Guam’s coral reefs, marine life, and coastal ecosystems. The Air Force has argued that the practice is essential for clearing unexploded ordnance from past military operations, including those dating to the 1944 Battle of Guam.
The Supreme Court’s decision could set a precedent for how federal agencies must comply with environmental laws during permit application processes. Legal experts note that the case may clarify whether agencies can be held accountable for actions taken during early stages of permitting, or if challenges must wait until a final decision is made. The outcome could also influence future military operations involving munitions disposal, particularly in environmentally sensitive areas.
Next Steps
The court is expected to issue a ruling in the coming months. If the justices side with the government, it could limit the ability of environmental groups to challenge military actions before permits are finalized. Conversely, a ruling in favor of the challengers could require the Air Force to conduct more rigorous environmental reviews before proceeding with detonations.
