EPA has announced that the second part of its eighth attempt to define the reach of the Clean Water Act will be delayed until November of 2023.  At the same time EPA announced it will move forward with finalizing part one of that attempt this fall.  That happens to be exactly the same time that the Supreme Court will be hearing oral argument in Sackett v. EPA, the nation's highest court's most recent attempt to define the reach of the Act.

Of course the first rule of holes is to stop digging and kudos to EPA for at least partially following that rule by delaying the second part of its most recent effort to resolve the longest running controversy in environmental law by almost two years to see how the Supreme Court affects what is possible.

EPA says part two of its rulemaking will be informed by "the experience of implementing" part one.   That "experience" will most certainly include defending the litigation that part one will provoke.   

EPA doesn't mention the possibility that Congress might act to resolve the controversy it created a half century ago in the meantime which is also a safe bet.
