Now that the 2015 extensions have been rolled back, federal water rules revert back to where they were in 1986. Experts say while the move has created uncertainty, it does not erase the bulk of federal water protections.
“Having the rule removed doesn’t remove the regulation,” said Colorado River District spokesman Chris Treese. “It doesn’t remove the protections that are still there. So I don’t think people have to worry.”

“There is state permitting and there is local permitting that would protect from any of the horribles that people suggest could happen.” Treese said. “That you could dump a toxic waste with impunity if the Trump era rule were in place. I don’t believe that’s true.”
