SACKETT ET UX. v. ENVIRONMENTAL PROTECTION AGENCY ET AL.
CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR THE NINTH CIRCUIT
No. 21–454. Argued October 3, 2022—Decided May 25, 2023
Petitioners Michael and Chantell Sackett purchased property near Priest Lake, Idaho, and began backfilling the lot with dirt to prepare for building a home. The Environmental Protection Agency informed the Sacketts that their property contained wetlands and that their backfilling violated the Clean Water Act, which prohibits discharging pollutants into “the waters of the United States.” 33 U. S. C. §1362(7). The EPA ordered the Sacketts to restore the site, threatening penalties of over $40,000 per day. The EPA classified the wetlands on the Sacketts’ lot as “waters of the United States” because they were near a ditch that fed into a creek, which fed into Priest Lake, a navigable, intrastate lake. The Sacketts sued, alleging that their property was not “waters of the United States.” The District Court entered summary judgment for the EPA. The Ninth Circuit affirmed, holding that the CWA covers wetlands with an ecologically significant nexus to traditional navigable waters and that the Sacketts’ wetlands satisfy that standard.
Held: The CWA’s use of “waters” in §1362(7) refers only to “geographic[al] features that are described in ordinary parlance as ‘streams, oceans, rivers, and lakes’ ” and to adjacent wetlands that are “indistinguishable” from those bodies of water due to a continuous surface connection. Rapanos v. United States, 547 U. S. 715, 755, 742, 739 (plurality opinion). To assert jurisdiction over an adjacent wetland under the CWA, a party must establish “first, that the adjacent [body of water constitutes] … ‘water[s] of the United States’ (i.e., a relatively permanent body of water connected to traditional interstate navigable waters); and second, that the wetland has a continuous surface connection with that water, making it difficult to determine where the ‘water’ ends and the ‘wetland’ begins.” Ibid. Pp. 6–28.
