Recent and Ongoing Activities

DOE has published a Federal Register notice rescheduling the automatic commercial ice makers (ACIMs) public meeting. On March 25, 2022, DOE published a notification of a webinar and availability of preliminary technical support document for ACIMs. The document announced a public meeting webinar would be held on April 25, 2022. Additionally, on March 24, 2022, DOE received a request from the Hoshizaki America, Inc. to move the webinar date due to a conflict with an industry-wide conference. To accommodate this scheduling issue, DOE is moving the public meeting webinar for ACIMs to Thursday, May 5, 2022.

  • DOE will hold a webinar on Thursday, May 5, 2022, from 1:00 p.m. to 4:00 p.m.

  • The TSD is available on the rulemaking docket.
  • Foreign Nationals interested in participating in this webinar, must be screened by DOE Headquarters Security prior to being granted access. Please email to complete the necessary documentation at least two weeks prior to scheduled meeting date.
  • Additional webinar registration information, participant instructions, and information about the capabilities available to webinar participants will be published on DOE’s website:

DOE has published a Federal Register notice announcing the availability of the preliminary analysis it has conducted for purposes of evaluating the need for amended energy conservation standards for automatic commercial ice makers, which is set forth in the Department’s preliminary technical support document (TSD) for this rulemaking. DOE will hold a public meeting via webinar to discuss and receive comment on its preliminary analysis. The meeting will cover the analytical framework, models, and tools used to evaluate potential standards for this equipment, the results of preliminary analyses performed by DOE, the potential energy conservation standard levels derived from these analyses (if DOE determines that proposed amendments are necessary), and other relevant issues.  In addition, DOE encourages written comments on these subjects.

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.
