President Trump has signed an executive order requiring the Environmental Protection Agency and Army Corps of Engineers to begin a process to cancel or rewrite an Obama administration rule that aimed to clarify the scope of federal authority over wetlands and other bodies of water.
The directive, which Trump signed on Feb. 28, doesn’t immediately wipe from the books the 2015 EPA-Corps rule defining federally regulated “waters of the United States”—although the president and other critics of the regulation clearly are looking for a major revision, at a minimum.
