U.S. Supreme Court Hears Oral Argument on WOTUS Rulemaking
Stakeholders looking to the Supreme Court for much-needed clarity on the definition of waters of the U.S. (WOTUS) under the Clean Water Act.

On October 3, 2022, the U.S. Supreme Court heard an oral argument in the case (Sackett v. EPA) that addresses the uncertain and inconsistent definition of waters of the U.S. (WOTUS) under the Clean Water Act (CWA). The debate centers on whether CWA jurisdiction extends to: (1) a narrow definition of wetlands – specifically, whether waters that are “relatively permanent, standing or continuously flowing” and to the wetlands that are immediately adjacent to such waters, or (2) a broader definition of wetlands – where there is a so-called “‘significant nexus’ between the wetlands in question and navigable waters in a traditional sense.”
Expectations for the Supreme Court’s Approach
Most observers expect the Supreme Court to take a middle-ground approach to the expansive “significant nexus” test and the more restrictive “permanent, standing, and continuously flowing” test, and provide much-needed direction for future rulemakings to define WOTUS. The Biden Administration has already indicated that it intends to wait for the Supreme Court decisions before proceeding with its new rulemaking to define WOTUS.
The Supreme Court could also apply the “major questions doctrine” that would require specific legislative authorization and direction from Congress before EPA and the Army Corps of Engineers (Corps) can finalize a revised definition of WOTUS on such a high-profile rulemaking. This could further delay or complicate a new decision from EPA and the Corps until Congress provides the requisite legislative authority.
The Supreme Court decision will provide some much-needed clarity on this issue. In the meantime, the long-term future of WOTUS will remain uncertain.
