The U.S. Department of Energy (DOE) received a petition from the Competitive Enterprise Institute (CEI) to define a new product class under the Energy Policy and Conservation Act, as amended (EPCA), for residential dishwashers. The new product class would cover dishwashers with a cycle time for the normal cycle of less than one hour from washing through drying. DOE published this petition and request for comments in the Federal Register on 24 April 2018. Based upon its evaluation of the petition and careful consideration of the public comments, DOE has decided to grant this petition for rulemaking and propose a dishwasher product class with a cycle time for the normal cycle of less than one hour. DOE intends to consider appropriate energy and water use limits for such a product class, if adopted, in a separate rulemaking.
