Recent and Ongoing Activities

DOE has published a Federal Register notice extending the comment period for the early assessment request for information (RFI) pertaining to the potential amendment of energy conservation standards for consumer boilers. The early assessment RFI that published in the Federal Register on March 25, 2021 provided an opportunity for submission of written comments, data, and information to the Department by April 26, 2021. Prior to the end of the comment period for the RFI, DOE received requests from the Air-Conditioning, Heating and Refrigeration Institute (AHRI), as well as from the American Public Gas Association (APGA), seeking additional time to consider the issues raised in the early assessment RFI. In light of these requests, DOE is announcing its decision to extend the comment period on the subject RFI for an additional 30 days.

  • Written comments and information are requested and will be accepted on or before May 26, 2021.
  • Interested persons are encouraged to submit comments using the Federal eRulemaking Portal at http://www.regulations.gov. Follow the instructions for submitting comments. Alternatively, interested persons may submit comments by email to the following address: Email: ConsumerBoilers2019STD0036@ee.doe.gov. Include “Consumer Boilers RFI” and docket number EERE-2019-BT-STD-0036 and/or RIN 1904-AE82 in the subject line of the message.

DOE has published a Federal Register notice undertaking an early assessment review for consumer boilers to determine whether to amend the applicable energy conservation standards for this product. Specifically, through this request for information (RFI), DOE seeks data and information to evaluate whether amended energy conservation standards would result in significant savings of energy, be technologically feasible, and be economically justified. DOE welcomes written comments from the public on any subject within the scope of this document (including those topics not specifically raised in this RFI), as well as the submission of data and other relevant information concerning this early assessment review.

DOE has published a Federal Register notice initiating a data collection process through this request for information (RFI), to consider whether to amend DOE’s current test procedure  for consumer boilers. DOE seeks data and information pertinent to whether amended test procedures would more accurately or fully comply with the requirement that the test procedure produces results that measure energy use during a representative average use cycle for the product, and not be unduly burdensome to conduct. 

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.
