On August 30, 2021, a U.S District Court for the District of Arizona said Trump’s Navigable Waters Protection Rule is illegal and should be vacated. The ruling restores protections for thousands of waterways across the Nation. It represents the culmination of a lawsuit brought by six federally recognized Indian tribes, who are represented by Earthjustice and sued the Environmental Protection Agency (EPA) and Army Corps of Engineers for passing a rule that eliminated Clean Water Act protections for thousands of waterbodies by redefining them as not “waters of the US.”
