DOE has published a Federal Register final rule on March 24, 2023 pertaining to test procedures for commercial and industrial pumps (pumps). This final rule amends the test procedure pumps to incorporate by reference relevant portions of the latest version of the industry testing standard, expands the scope of clean water pumps covered by this test procedure, revises calculation methods for pumps sold with motors and controls to better represent field energy use, adds and updates certain definitions, and allows the use of alternative efficiency determination methods for the rating and certification of pumps.

• The effective date of this rule is April 24, 2023. The amendments will be mandatory for product testing starting September 20, 2023.
• The incorporation by reference of certain materials listed in the rule is approved by the Director of the Federal Register September 20, 2023.
• The incorporation by reference of certain other material listed in the rule was approved by the Director of the Federal Register on January 25, 2016.
• On April 21, 2023, DOE published a correction notice to correct numbering and amendatory errors in the March 24, 2023 final rule.

Certain pumps manufactured and distributed in commerce, as defined by 42 U.S.C. 6291(16), must meet the energy conservation standards specified in the Code of Federal Regulations at 10 CFR 431.465.

To determine that pumps that are currently manufactured or distributed into commerce are in compliance with DOE standards, manufacturers must follow the test procedure methods specified at 10 CFR part 431, subpart Y, appendix A.
