A Trump administration move to delay the implementation date of an Obama-era Clean Water rule has sparked a new legal battle.
Under a decision published on Feb. 6 in the Federal Register, the “waters of the U.S.,” or WOTUS, rule won’t be applicable until Feb. 6, 2020. By that date, the Environmental Protection Agency and Army Corps of Engineers expect to have repealed and replaced the 2015 rule with a new, less expansive one.
