On May 25, 2023, the U.S. Supreme Court issued a highly-anticipated decision that significantly narrows the extent of wetlands within the definition of “waters of the United States” (WOTUS), and, therefore, within the jurisdiction of the federal Clean Water Act (CWA). Under the majority opinion in Sackett v. EPA, the Court held that “waters” are limited to “only those relatively permanent standing or continuously flowing bodies of water” that are described as “streams, oceans, rivers, and lakes” and to “adjacent” wetlands that are “indistinguishable” from those bodies of water. Therefore, a wetland is only a WOTUS (and subject to CWA jurisdiction) if: (1) the adjacent body of water is a WOTUS (i.e., “a relatively permanent body of water connected to a traditional interstate navigable water”); and (2) the wetland has a “continuous surface connection” with that water “making it difficult to determine where the ‘water’ ends and the ‘wetland’ begins.” As Justice Samuel Alito stated: Federally regulated wetlands “must be indistinguishably part of a body of water that itself constitutes ‘waters’ under the CWA. . . . Wetlands that are separate from traditional navigable waters cannot be considered part of those waters, even if they are located nearby.”
The Sackett litigation involves Michael and Chantell Sackett, who have been unable to build a house because the U.S. Environmental Protection Agency (USEPA) and the U. S. Army Corps of Engineers (the Corps) determined that a wetland on their Idaho property was a WOTUS, requiring CWA Section 404 permitting. Both the U.S. District Court for the District of Idaho and the Ninth Circuit sided with the Agencies’ WOTUS determination, citing the “significant nexus” test introduced by Justice Anthony Kennedy in his concurring opinion in the U.S. …
