Pruitt and the Army Corps began sending letters to state agencies asking for their feedback on changing a key definition for waterways under the rule.”The Army, together with the Corps of Engineers, is committed to working closely with and supporting the EPA on these rulemakings,” according to Douglas Lamont, a senior official acting as the assistant secretary of the Army for Civil Works. “As we go through the rulemaking process, we will continue to make the implementation of the Clean Water Act Section 404 regulatory program as transparent as possible for the regulated public.”The process to rewrite the water rule follows President Trump’s executive order from February directing the agencies to reconsider the regulation in line with the opinion of late Supreme Court Justice Antonin Scalia in 2006. Scalia had laid out a framework in the case Rapanos v. United States that said the EPA’s Clean Water Act authority should extend only to waterways that are permanent.
