I share your concerns. Do the agencies that are supposed to carry out the legislation have more power to enforce their regulations or does Congress, who passed the law? What is happening with these rogue agencies and bureaucrats is not what the founding fathers envisioned.
This rule is just another attempt to circumvent the law. The law says they can regulate “navigable waters”. The EPA has already tried this twice, and both times they have lost at SCOTUS. The law is above any rule, and when taken to court again, again they will lose. I would say to everyone, if it’s not navigable waters, ignore them.
