EPA and Army Corps Propose New Definition for WOTUS
December 1st, 2025 — by Taylor Young — Category: Clean Water Act
On November 17, 2025, the U.S. Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers (Corps) proposed a new rule to change the definition of “waters of the United States” (WOTUS). Defining WOTUS may seem technical or insignificant, but it is central to understanding which bodies of water are subject to federal jurisdiction under the Clean Water Act (CWA). It affects day-to-day decisions such as how to comply with federal law, when permits are required, and which permits are needed. According to the EPA and the Corps, by providing a clear and durable definition, this proposal may help accelerate economic growth and opportunities.
