Energy Conservation Program for 
Appliance Standards: Energy Conservation Standards for Residential Furnaces and Commercial Water Heaters: Notification of Proposed Interpretive Rule 
AGENCY : Office of Energy Efficiency and 
Renewable Energy, Department of Energy. 
ACTION : Notification of proposed 
interpretive rule; extension of public comment period. 
SUMMARY : On January 15, 2021, the U.S. 
Department of Energy (DOE or the Department) published in the Federal Register a final interpretive rule 
determining that, in the context of residential furnaces, commercial water heaters, and similarly-situated products or equipment, use of non-condensing technology (and associated venting) constitutes a performance-related ‘‘feature’’ under the Energy Policy and Conservation Act, as amended (EPCA), that cannot be eliminated through the adoption of an energy conservation standard. On August 27, 2021, DOE published in the Federal Register a notification of proposed interpretive rule (NOPIR) that proposes to return to its previous and long-standing interpretation, under which the technology used to supply heated air or hot water is not a performance related ‘‘feature’’ that provides a distinct consumer utility under EPCA. The NOPIR provided an opportunity for submission of written comments, data, and information to the DOE no later than September 27, 2021. Prior to the end of that comment period, several stakeholders submitted a joint request seeking additional time to consider the issues raised in the NOPIR. In light of this request, DOE is extending the comment period on the subject NOPIR for an additional 15 days. 
DATES : The comment period for the 
NOPIR published in the Federal Register on August 27, 2021 (86 FR 
48049) is extended to October 12, 2021. Written comments, data, and information are requested and will be accepted on and before October 12, 2021. 
ADDRESSES : Interested persons are 
encouraged to submit comments using the Federal eRulemaking Portal at www.regulations.gov. Follow the 
instructions for submitting comments. Alternatively, interested persons may submit comments by email to the following address: Email: ResFurnaceCommWaterHeater2018STD0018@ee.doe.gov. Include docket number 
EERE–2018–BT–STD–0018 and/or RIN 1904–AE39 in the subject line of the message. Submit electronic comments in WordPerfect, Microsoft Word, PDF, or ASCII file format, and avoid the use of special characters or any form of encryption. No telefacsimiles (faxes) will be accepted. 
Although DOE has routinely accepted 
public comment submissions through a variety of mechanisms, including postal mail and hand delivery/courier, the Department has found it necessary to make temporary modifications to the comment submission process in light of the ongoing COVID–19 pandemic. DOE is currently accepting only electronic submissions at this time. If a commenter finds that this change poses an undue hardship, please contact Appliance Standards Program staff at (202) 586– 1445 to discuss the need for alternative arrangements. Once the COVID–19 pandemic health emergency is resolved, DOE anticipates resuming all of its regular options for public comment submission, including postal mail and hand delivery/courier. 
Docket: The docket for this activity, 
which includes Federal Register notices, comments, and other supporting documents/materials, is available for review at www.regulations.gov. All documents in 
the docket are listed in the www.regulations.gov index. However, 
some documents listed in the index, such as those containing information that is exempt from public disclosure, may not be publicly available. The docket web page can be found at:

SUPPLEMENTARY INFORMATION : On 
January 15, 2021, the U.S. Department of Energy (DOE or the Department) published in the Federal Register a final interpretive rule determining that, in the context of residential furnaces, commercial water heaters, and similarly-situated products or equipment, use of non-condensing technology (and associated venting) constitutes a performance-related ‘‘feature’’ under EPCA (42 U.S.C. 6291 et seq.), as amended, that cannot be eliminated through the adoption of an energy conservation standard. 86 FR 4776. On August 27, 2021, DOE published in the Federal Register a NOPIR that proposes to return to its previous and long-standing interpretation (in effect prior to the January 2021 final interpretive rule), under which the technology used to supply heated air or hot water is not a performance related ‘‘feature’’ that provides a distinct consumer utility under EPCA. 86 FR 48049. The NOPIR provided an opportunity for submission of written comments, data, and information to the Department no later than September 27, 2021. 
Prior to the end of the comment 
period for the NOPIR, DOE received a joint comment from the American Gas Association (AGA), the American Public Gas Association (APGA), Spire Inc. and Spire Missouri (Spire), and the National Propane Gas Association (NPGA),

2Energy Conservation Standards for Residential 
Furnaces, Docket No. EERE–2014–BT–STD–0031, 
and Energy Conservation Standards for Commercial Water Heaters, Docket No. EERE–2014–BT–STD– 0042. collectively referred to as the ‘‘Gas 
Industry Commenters,’’ requesting an additional 60 days for public comment in order to consider the issues raised in the NOPIR.
1The Gas Industry 
Commenters requested additional time due to their assertion that DOE’s proposal raises various factual, technical, economic, regulatory, and administrative issues that require significant time to review and to respond in a meaningful manner. The Gas Industry Commenters also pointed out the length of the comment periods under the proceeding that culminated in the January 2021 final interpretive rule, as well as the comment extensions that DOE granted throughout that interpretive rulemaking process. 
Furthermore, the Gas Industry 
Commenters noted that stakeholders are currently engaged in multiple DOE- related proceedings, both before the agency and the court, and each matter requires sufficient engagement. The Gas Industry Commenters also argued that the COVID–19 emergency continues to adversely impact stakeholder engagement and expressed their belief that a sixty-day comment extension will not cause a significant delay in DOE’s consideration of the record and any next steps. 
In regard to the assertion that the 
August 2021 NOPIR raises various issues that require significant time to review and respond to, DOE notes the NOPIR does not raise new issues but rather proposes to return to DOE’s long- standing, historical interpretation. DOE further notes that the various factual, technical, economic, regulatory, and administrative issues are well understood, have been discussed at 
length, and have been documented in a number of rulemaking dockets.
2Also, as 
noted in the August 2021 NOPIR, Executive Order (E.O.) 13990, ‘‘Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis,’’ 86 FR 7037 (Jan. 25, 2021), triggered the Department’s reevaluation of the January 2021 final interpretive rule. 86 FR 48049, 48050–48051 (August 27, 2021). 
After carefully reviewing the 
submission, DOE has considered the urgency required under E.O. 13990 along with the competing benefit to stakeholders in providing additional time to review and comment on the NOPIR. Accordingly, in seeking to balance the interests at issue, DOE has determined that it is appropriate to partially grant this request and to extend the comment period by 15 days, thereby allowing additional time for interested parties to prepare and submit comments. Therefore, DOE is extending the comment period for the NOPIR and will accept comments, data, and information on this matter received on and before October 12, 2021. Accordingly, DOE will consider any comments received by this date to be timely submitted.

Airworthiness Directives; Bell Textron 
Canada Limited Helicopters 
AGENCY : Federal Aviation 
Administration (FAA), DOT. 
ACTION : Notice of proposed rulemaking 
(NPRM). 
SUMMARY : The FAA proposes to adopt a 
new airworthiness directive (AD) for Bell Textron Canada Limited Model 206L–1, 206L–3, and 206L–4 helicopters with certain Air Comm Corporation (Air Comm) air conditioning systems installed. This proposed AD would require visually inspecting the drive ring spline teeth and the mating area spline teeth on the oil cooler blower shaft for signs of deformation and fretting and depending on the results of the inspection, removing certain parts from service. This proposed AD would also require reinstalling certain parts, applying torque, and aligning certain bolt holes. This proposed AD was prompted by reports of damage to the drive ring spline teeth and the mating spline teeth. The actions of this proposed AD are intended to address an unsafe condition on these products. 
DATES : The FAA must receive comments 
on this proposed AD by November 8, 2021.
