Last week, the U.S. Environmental Protection Agency (EPA) and U.S. Army Corps of Engineers announced that the regulations defining “waters of the United States” under the Federal Water Pollution Control Act (better known as the Clean Water Act) are once again going to change.
The importance of that announcement is best demonstrated through a quick recap of the chaos that has dominated this element of Clean Water Act jurisdiction. In the 1980s, the EPA and Army Corps finally agreed on a regulatory definition of “waters of the United States,” a phrase that Congress had used in its 1972 overhaul of the Federal Water Pollution Control Act to define “navigable waters.” The phrase is also one of the key jurisdictional terms defining the waters to which the restructured law applies.
“Waters of the United States” indicates that jurisdictional waters are broader than the traditional navigable waters — that is, waters that are navigable in fact or subject to the ebb and flow of the tide.

In the first part of this post, I briefly touched on the chaotic history of the EPA and Army Corps' definition and regulation of "waters of the United States" under the Clean Water Act. I also pointed out that this definition and its varying interpretations across courts and administrations can have significant impacts on water pollution prevention and the protection of our nation's waterways. With the Biden administration tackling a redo of the "waters of the United States" rule, court challenges are sure to follow. In this post, I'll explore three approaches to the rule that might help it survive judicial review.
