Providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Department of Energy relating to the "Energy Conservation Program: Test Procedure for Consumer Water Heaters and Residential-Duty Commercial Water Heaters".

H.J.Res. 91 is a joint resolution that seeks to overturn a specific Department of Energy rule regarding the testing procedures for consumer and residential-duty commercial water heaters. By utilizing the Congressional Review Act, the bill would prevent the federal government from implementing new standardized methods used to measure the energy efficiency and water consumption of these appliances. If passed, the resolution would maintain existing testing standards and prohibit the Department of Energy from issuing a substantially similar rule in the future without new legislative authorization. For citizens, this would mean that the energy labels and efficiency ratings found on new water heaters would continue to be calculated under previous guidelines rather than the updated federal requirements.
