State of Arizona v. EPA, No. 21-1159 (D.C. Cir. 2023)
Annotate this Case
The Environmental Protection Agency extended the deadline for compliance with a revised national drinking water regulation, which in turn extended the deadline for states to enforce conforming revisions to their own regulations. Five states seek to challenge the federal extension, which they say will cause them various harms.
The DC Circuit dismissed the petition for review for lack of Article III standing. The court explained that the states’ uncertainty also is not redressable in this litigation. Their harm is not knowing what future obligations they will face, making it difficult to plan. But the Delay Rule gives the states more time to hedge their bets. Setting it aside would worsen any problem of regulatory uncertainty, taking as a given EPA’s unreviewable decision to consider changes to the Revision Rule.
