The Energy Policy and Conservation Act, as amended, 42 U.S.C. 6291–6309 (EPCA) establishes energy conservation or water use standards and test procedures for certain consumer products, including faucets. Title 10 of the Code of Federal Regulations, Part 430 (10 CFR 430), defines the term “faucet” to mean a lavatory faucet, kitchen faucet, metering faucet or replacement aerator for a lavatory or kitchen faucet. (10 CFR 430.2) The Department of Energy (DOE) last amended the test procedures for faucets on September 30, 2013. Under the provisions of 42 U.S.C. 6295(j)(3), the water use standards for faucets have not been amended.
DOE has published a Federal Register notice proposing to rescind the amended water use standards for faucets. If finalized, this will reset existing water use requirements for faucets to the statutory standard.
For the latest information on the planned timing of future DOE regulatory milestones, see the current Office of Management and Budget Unified Agenda of Regulatory and Deregulatory Actions. All planned dates are preliminary and subject to change.
STANDARDS
Notice of Proposed Rulemaking - Federal Register, 90FR20854 (May 16, 2025)
The Energy Policy Act of 1992 amended EPCA to add water conservation standards for faucets, based on the flow rate requirements contained in American Society of Mechanical Engineers (ASME)/American National Standards Institute (ANSI) Standard A112.18.1M-1989, which are codified under Title 42 of the U.S. Code (42 U.S.C.) section 6295(j). Under 42 U.S.C. 6295(j)(3), if the maximum flow rate requirements contained in ASME/ANSI Standard A112.18.1M are amended to improve the efficiency of water use, the Secretary of Energy shall consider establishing an amended uniform national standard at the level specified in the amended ASME/ANSI Standard. To date, ASME has not updated the flow rate requirements for faucets.

Submitting Public Comments
The comment period is closed.
The flow rate of a faucet manufactured and distributed in commerce, as defined by 42 U.S.C. 6291 (10) and (16) respectively, must not be greater than the maximum water use standards under 10 CFR 430.32(o).
To determine whether a faucet is in compliance with the water use standards under 10 CFR 430.32 (o), a manufacturer must measure the maximum flow rate in accordance with 10 CFR 430, Appendix S of Subpart B.
Compliance
DOE has established regulations on certification, compliance, and enforcement in 10 CFR Part 429. These regulations cover statistical sampling plans, certified ratings, certification reports, record retention, and enforcement. More information about compliance and enforcement is available on DOE's Implementation webpage.
Waivers
For information on current test procedure waivers, see DOE’s Waivers webpage.
For information about obtaining test procedure waivers, see 10 CFR 430.27.
Exceptions
DOE's Office of Hearings and Appeals has not authorized exception relief for faucets.
For information about obtaining exception relief, see 10 CFR part 1003
Guidance and Frequently Asked Questions

State Exemptions to Federal Pre-emption
A state may petition DOE for exemption from preemption of a federal water conservation standard in certain cases of unusual or compelling state or local water interests. A state may also petition DOE to withdraw such exemption. See 10 CFR part 430, subpart D. DOE has not exempted any state from this water conservation standard.
On December 22, 2010, DOE published in the Federal Register a final rule to waive the general rule of federal preemption for water use standards, under 42 U.S.C. 6297(c), with respect to any state regulation concerning faucets if such state regulation is (1) more stringent than Federal regulation concerning the water use or water efficiency for that same type or class of product, and (2) applicable to any sale or installation of all products in that particular type or class. 75 FR 80289.
Small Business Exemptions
Any manufacturer of a covered product with annual gross revenues that do not exceed $8,000,000 from all its operations and meets certain other conditions may apply for an exemption to the energy conservation standard. For details, see 10 CFR part 430, subpart E.
