The competing views
The Court accepted two questions: whether the application is final agency action and whether NEPA review must precede it. This selection tracks only the first. A ruling about NEPA alone does not resolve this selection.
The Air Force says an application neither completes its decisionmaking nor directly changes legal rights. It also argues that the specific hazardous-waste permitting process displaces a separate NEPA review.
Prutehi Guahan says the renewal application commits the Air Force to continued operations and preserves the existing permit. It argues that the permitting law does not excuse NEPA’s environmental analysis.
