DOE proposed to rescind the efficiency standards for external power supplies (EPS), codified in 10 CFR 430.32(w). On September 19, 2011, DOE adopted new energy conservation standards for EPSs. DOE again amended the energy conservation standard on February 10, 2014. After reevaluation of these EPS standards, DOE now has tentatively determined that “the standards legislated by Congress do not require amendment and the current regulatory standards are not economically justified.” Notably, though DOE may not prescribe any amended standard which “increases the maximum allowable energy use, or, in the case of showerheads, faucets, water closets, or urinals, water use, or decreases the minimum required energy efficiency, of a covered product.” 42 U.S.C. 6295(o)(1), DOE claims that it has reevaluated its statutory authority and tentatively determined that when DOE rescinds a rule in full it has not “prescribe[d] any amended standard” that falls under the anti-backsliding provision. DOE also asserted that the anti-backsliding provision only prevents DOE from setting standards below the statutory maximum or minimum, irrespective of subsequent regulatory amendments.
