AGENCY:

Office of Energy Efficiency and Renewable Energy, Department of Energy.

ACTION:

Notification of data availability (NODA), public meeting, and extension of the comment period.

SUMMARY:

On July 7, 2022, the U.S. Department of Energy (“DOE” or “the Department”) published in the Federal Register a notice of proposed rulemaking (“NOPR”) for amending the energy conservation standards for certain consumer furnaces, specifically non-weatherized gas furnaces (“NWGF”) and mobile home gas furnaces (“MHGF”). In response to requests by several interested parties, the U.S. Department of Energy (“DOE”) is making available a revised version of the life-cycle-cost (“LCC”) spreadsheet supporting that NOPR and also announcing a public meeting webinar to assist stakeholders with operation of the LCC spreasheet. In addition, DOE received four requests to extend the public comment period for the NOPR (originally set to close September 6, 2022), and after considering those requests, the Department has decided to extend the public comment period until October 6, 2022.

DATES:

Comments: The comment period for the NOPR published in the Federal Register on July 7, 2022 (87 FR 40590) is extended until October 6, 2022. Written comments, data, and information are requested and will be accepted on and before October 6, 2022. See section II, “Public Participation,” of this document for details.

Meeting: DOE will hold a webinar on Tuesday, September 6, 2022, from 1:00 p.m. to 3:00 p.m. on the life-cycle cost model for the consumer furnaces rulemaking. See section II, “Public Participation,” for webinar registration information, participant instructions, and information about the capabilities available to webinar participants.

I. Background and Summary

On July 7, 2022, the U.S. Department of Energy (“DOE”) published in the Federal Register a notice of proposed rulemaking (“NOPR”) for amending the energy conservation standards for certain consumer furnaces, specifically non-weatherized gas furnaces (“NWGF”) and mobile home gas furnaces (“MHGF”) (“July 2022 NOPR”). 87 FR 40590. As part of that rulemaking proceeding, DOE also made available a life-cycle-cost (“LCC”) and payback period (“PBP”) analysis spreadsheet, and a Technical Support Document (“TSD”) in the rulemaking docket. The TSD describes the various analyses, including the LCC analysis, performed in support of the NOPR.

The computer model DOE uses to calculate the LCC and PBP relies on Monte Carlo simulations to incorporate uncertainty and variability into the analysis. The Monte Carlo simulations randomly sample input values from probability distributions and NGWF and MHGF user samples. For this rulemaking, the Monte Carlo approach is implemented in MS Excel together with the Crystal Ball add-on. The model calculated the LCC and PBP for products at each efficiency level for 10,000 furnace installations per simulation run. The analytical results include a distribution of 10,000 data points showing the range of LCC savings for a given efficiency level relative to the no-new-standards case efficiency distribution.

In the version of the LCC spreadsheet that DOE published in July accompanying the NOPR, the specific sequence of random numbers utilized by the Monte Carlo simulation was inadvertently changed from the version of the analysis presented in the NOPR and the TSD. As a result, the published LCC spreadsheet produces similar results to the NOPR and TSD that support the same policy outcome, but the currently published version of the LCC spreadsheet will not provide exactly the same results as the NOPR or technical support document tables. This is expected behavior for a Monte Carlo simulation relying on random number generation if the sequence of random numbers is allowed to change. The relative comparison of the various proposed energy conservation standard levels in the published LCC spreadsheet remains similar to the comparison presented in the NOPR. DOE notes that the conclusions of the analysis, the policy decision, and associated rationale are not impacted by this sampling variability.

In this notice of data availability (“NODA”), DOE is announcing that the Department is making available in the docket of the rulemaking and on the furnace rulemaking website page to interested persons a revised version of the LCC spreadsheet in which the random number generation is fixed in place, thereby producing the same results as presented in the NOPR and TSD.

Additionally, DOE held a public meeting webinar on August 3, 2022 to discuss the analyses and proposals presented in the July 2022 NOPR, at which several interested parties requested that DOE hold a separate meeting to further explain the LCC spreadsheet. In addition, on August 11, 2022, the American Gas Association (“AGA”), American Public Gas Association (“APGA”), National Propane Gas Association (“NPGA”), Spire Inc, Spire Missouri Inc, Spire Alabama Inc, and Atmos Energy Corporation (“Atmos Energy”) (collectively, “Joint Requesters”) submitted a joint comment reiterating their request from the August 3, 2022 webinar that DOE hold a separate workshop on its LCC model. (Joint Requesters, No. 345 at p. 1) DOE notes that the NWGF and MHGF LCC spreadsheet has additional complexities beyond those typically found in LCC spreadsheets, such as those related to fuel switching, extended repair vs. replacement, potential downsizing of furnace capacity, and many installation cost factors. Given the increased complexity of the LCC spreadsheet for NWGF and MHGF, and after considering the comments and requests from interested parties, DOE has determined that an additional webinar focused on the LCC spreadsheet is appropriate. Accordingly, DOE will hold a public meeting webinar on Tuesday, September 6, 2022, to provide instruction on the operation of the LCC spreadsheet to interested persons.

Lastly, the in the July 2022 NOPR, DOE stated it would accept written comments, data, and information on the proposal until September 6, 2022. 87 FR 40590, 40590 (July 7, 2022). DOE received four requests for an extension of the NOPR public comment period. On July 25, 2022, DOE received a joint request from the Joint Requesters to extend the public comment period by 60 days. (Joint Requesters, No. 330 at p. 1) On August 3, 2022, DOE received a request from the Natural Gas Supply Association (NGSA), supporting the Joint Requestors' submission requesting a 60-day extension of the comment period. (NGSA, No. 343 at p. 1) On August 9, 2022, DOE received a submission from the Manufactured Housing Institute (“MHI”) supporting the Joint Requestors' submission and requesting an extension of the comment period. (MHI, No. 344 at p. 1)

On August 11, 2022, DOE received a second submission from the Joint Requestors, which, as discussed previously, requested that DOE hold a workshop on the LCC model. The Joint Requestors also urged that the comment period be extended by 45 days after the receipt of the results of the workshop. (Joint Requesters, No. 345 at p. 1)

DOE has reviewed these requests. Based on these requests, this NODA, and the newly scheduled webinar, DOE is extending the comment period to allow additional time for interested parties to review the revised LCC spreadsheet, participate in the webinar, and provide comments on the NOPR and associated docketed materials. DOE believes that allowing 30 days after the workshop is sufficient and is responsive to the requestors. Therefore, DOE is extending the NOPR comment period until October 6, 2022.
