The Biden Administration just announced that it intends to plunge the country back into the uncertainty of pre-2015 by repealing the USEPA/Army Corps' Navigable Waters Protection Rule, adopted in 2020.  The 2020 ruled was hailed by farmers and ranchers as adhering to the contours of jurisdiction granted by Congress in the Clean Water Act and harmonizing several decisions of the US Supreme Court.  This decision will begin yet another arduous rulemaking process as the regulatory ping-ponging continues.
