On May 9, 2025, President Trump issued a memorandum directing the Department of Energy to rescind or amend several water conservation and efficiency standards, which are required by the Energy Policy Act of 1992. Specifically, it directs the "Secretary of Energy to consider using all lawful authority to rescind — or, as appropriate, amend to revert to the standards required by statute — the regulations found in 10 C.F.R. 430.32(f), relating to water and energy use in dishwashers; 10 C.F.R. 430.32(o), relating to water use in faucets; 10 C.F.R. 430.32(p), relating to water use in showerheads; 10 C.F.R. 430.32(q), relating to water use in water closets; 10 C.F.R. 430.32(r), relating to water use in urinals; the definitions of “automatic clothes washer,” “clothes washer,” “dishwasher,” “faucet,” “other clothes washer,” “semi-automatic clothes washer,” “urinal,” and “water closet” contained in 10 C.F.R. 430.2; the residential washing machine efficiency standards contained in 10 C.F.R. 430.32(g); and the commercial washing machine efficiency standards contained in 10 C.F.R. 431.156."
In the interim, the memorandum also instructs the Department of Energy not to enforce the current standards.
