In the August 4, 2021 Federal Register (WOTUS_Fed Reg_2021-08-04) the US Environmental Protection Agency (EPA) and the US Army Corps of Engineers (ACOE) announced a series of public meetings and roundtables as they develop a revised definition of “Waters of the United States” (WOTUS).  Per the enclosed notice, there will be two rulemaking steps.

The first rulemaking is referred to as a “foundational rule” that will “restore longstanding protections.”  The intent is to “restore the regulations defining WOTUS that were “were in place for decades until 2015, with updates to be consistent with relevant Supreme Court decisions.”  The second rulemaking will build “on that regulatory foundation.”
