Recent and Ongoing Activities
DOE has published a Federal Register final rule pertaining to test procedures for consumer boilers. DOE amends its test procedure for consumer boilers established under the Energy Policy and Conservation Act. This rulemaking fulfills DOE’s obligation to review its test procedures for covered products at least once every seven years. The revisions include: incorporating by reference the latest versions of the industry standards currently referenced in the Federal test procedure; relocating the test procedure to a new appendix separate from the residential furnace test procedure; removing an extraneous definition from its regulatory definitions; and making clarifying corrections to calculations. These revisions will improve the representativeness of the test method and will not be unduly burdensome to conduct.
- The effective date of this rule is April 12, 2023.
- The amendments will be mandatory for product testing starting starting September 11, 2023.
- The incorporation by reference of certain materials listed in the rule is approved by the Director of the Federal Register April 12, 2023.
- The incorporation by reference of certain other material listed in the rule was approved by the Director of the Federal Register on March 23, 2009, and February 16, 2016.
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.
