 ACTION: Notification of availability of preliminary technical support document and request for comment.
 SUMMARY: The U.S. Department of Energy (“DOE” or “the Department”) announces the availability of the preliminary analysis it has conducted for purposes of evaluating the need for amending the current energy conservation standards for walk-in coolers and freezers (“walk-ins” or “WICFs”). The analysis is set forth in the Department's accompanying preliminary technical support document (“TSD”) for this rulemaking. DOE will hold a public meeting via webinar to discuss and receive comment on the preliminary analysis. The meeting will cover the analytical framework, models, and tools that DOE is using to evaluate potential standards; 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.

Authority The Energy Policy and Conservation Act, as amended (“EPCA”),[1]
                    
                     authorizes DOE to regulate the energy efficiency of a number of consumer products and certain industrial equipment. (42 U.S.C. 6291-6317) Title III, Part C [2]
                    
                     of EPCA established the Energy Conservation Program for Certain Industrial Equipment. This equipment includes walk-in coolers and walk-in freezers, the subject of this document. (42 U.S.C. 6311(1)(G)) EPCA prescribes a set of basic requirements for walk-ins. First, all walk-in doors narrower than 3 feet 9 inches and shorter than 7 feet must have automatic door closers that firmly close all walk-in doors that have been closed to within 1 inch of full closure. All walk-ins must also have strip doors, spring hinged doors, or other methods of minimizing infiltration when doors are open. Additionally, walk-ins must contain wall, ceiling, and door insulation of at least R-25 for coolers and R-32 for freezers, excluding glazed portions of doors and structural members, and floor insulation of at least R-28 for freezers. Walk-in evaporator fan motors of under 1 horsepower (“hp”) and less than 460 volts must be electronically commutated motors (brushless direct current motors) or three-phase motors, and walk-in condenser fan motors of under 1 horsepower must use permanent split capacitor motors, electronically commutated motors, or three-phase motors. Interior light sources must have an efficacy of 40 lumens per watt or more, including any ballast losses; less-efficacious lights may only be used in conjunction with a timer or device that turns off the lights within 15 minutes of when the walk-in is unoccupied. (
                    *See*42 U.S.C. 6313(f)(1)) Additionally, EPCA requires that walk-in freezers with transparent reach-in doors and windows must have triple-pane glass with either heat-reflective treated glass or gas fill. Transparent walk-in cooler doors and windows must have either double-pane glass with heat-reflective treated glass and gas fill or triple-pane glass with heat-reflective treated glass or gas fill. (42 U.S.C. 6313(f)(3)(A)-(B)) EPCA also prescribes specific anti-sweat heater-related requirements: Walk-ins without anti-sweat heater controls must have a heater power draw of no more than 7.1 or 3.0 watts per square foot of door opening for freezers and coolers, respectively. If walk-ins have a heater power draw of more than 7.1 or 3.0 watts per square foot of door opening for freezers and coolers, respectively, then the walk-in must have anti-sweat heater controls that reduce the energy use of the heater in a quantity corresponding to the relative humidity of the air outside the door or to the condensation on the inner glass pane. 
                    *See*42 U.S.C. 6313(f)(3)(C)-(D). Additionally, EPCA prescribed two cycles of WICF-specific rulemakings; the first to establish performance-based standards that achieve the maximum improvement in energy that the Secretary determines is technologically feasible and economically justified, and the second to determine whether to amend those standards. (42 U.S.C. 6313(f)(4) and (5)) DOE has satisfied the first of these requirements. 
                    *See*79 FR 32050 (June 3, 2014) (establishing WICF performance standards) and 82 FR 31808 (July 10, 2017) (addressing prior rulemaking errors by amending certain refrigeration system class standards). This document addresses the second cycle of rulemaking. EPCA further provides that, not later than 6 years after the issuance of any final rule establishing or amending a standard, DOE must publish either a notification of determination that standards for the equipment do not need to be amended, or a notice of proposed rulemaking (“NOPR”) including new proposed energy conservation standards (proceeding to a final rule, as appropriate). (42 U.S.C. 6316(a); 42 U.S.C. 6295(m)(1)) Not later than three years after issuance of a final determination not to amend standards, DOE must publish either a notice of determination that standards for the equipment do not need to be amended, or a NOPR including new proposed energy conservation standards (proceeding to a final rule, as appropriate). (42 U.S.C. 6316(a); 42 U.S.C. 6295(m)(3)(B)) Under EPCA, any new or amended energy conservation standard must be designed to achieve the maximum improvement in energy efficiency that DOE determines is technologically feasible and economically justified. (42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(2)(A)) Furthermore, the new or amended standard must result in a significant conservation of energy. (42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(3)(B)) DOE is publishing this Preliminary Analysis to collect data and information to inform its decision consistent with its obligations under EPCA. B. Rulemaking Process DOE must follow specific statutory criteria for prescribing new or amended standards for covered equipment, including walk-ins. As noted, EPCA requires that any new or amended energy conservation standard prescribed by the Secretary of Energy (“Secretary”) be designed to achieve the maximum improvement in energy efficiency (or water efficiency for certain products specified by EPCA) that is technologically feasible and 
                    ( print page 39010)
                    economically justified. (42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(2)(A)) Furthermore, DOE may not adopt any standard that would not result in the significant conservation of energy. (42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(3)) The significance of energy savings offered by a new or amended energy conservation standard cannot be determined without knowledge of the specific circumstances surrounding a given rulemaking.[3]
                    
                     For example, the United States has now rejoined the Paris Agreement on February 19, 2021. As part of that agreement, the United States has committed to reducing greenhouse gas (“GHG”) emissions in order to limit the rise in mean global temperature.[4]
                    
                     As such, energy savings that reduce GHG emission have taken on greater importance. Additionally, some covered products and equipment have most of their energy consumption occur during periods of peak energy demand. The impacts of these products on the energy infrastructure can be more pronounced than products with relatively constant demand. In evaluating the significance of energy savings, DOE considers differences in primary energy and FFC effects for different covered products and equipment when determining whether energy savings are significant. Primary energy and FFC effects include the energy consumed in electricity production (depending on load shape), in distribution and transmission, and in extracting, processing, and transporting primary fuels (
                    *i.e.,*
                     coal, natural gas, petroleum fuels), and thus present a more complete picture of the impacts of energy conservation standards. Accordingly, DOE evaluates the significance of energy savings on a case-by-case basis. DOE has initially determined the energy savings for the candidate standard levels evaluated in this preliminary analysis rulemaking are “significant” within the meaning of 42 U.S.C. 6295(o)(3)(B). To determine whether a standard is economically justified, EPCA requires that DOE determine whether the benefits of the standard exceed its burdens by considering, to the greatest extent practicable, the following seven factors: (1) The economic impact of the standard on the manufacturers and consumers of the products subject to the standard; (2) The savings in operating costs throughout the estimated average life of the covered products in the type (or class) compared to any increase in the price, initial charges, or maintenance expenses for the covered products that are likely to result from the standard; (3) The total projected amount of energy (or as applicable, water) savings likely to result directly from the standard; (4) Any lessening of the utility or the performance of the products likely to result from the standard; (5) The impact of any lessening of competition, as determined in writing by the Attorney General, that is likely to result from the standard; (6) The need for national energy and water conservation; and (7) Other factors the Secretary of Energy (Secretary) considers relevant. (42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(2)(B)(i)(I)-(VII)) DOE fulfills these and other applicable requirements by conducting a series of analyses throughout the rulemaking process. Table I.1 shows the individual analyses that are performed to satisfy each of the requirements within EPCA. Table I.1—EPCA Requirements and Corresponding DOE Analysis

 Further, EPCA establishes a rebuttable presumption that a standard is economically justified if the Secretary finds that the additional cost to the consumer of purchasing equipment complying with an energy conservation standard level will be less than three times the value of the energy savings during the first year that the consumer will receive as a result of the standard, as calculated under the applicable test procedure. (42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(2)(B)(iii)) EPCA also contains what is known as an “anti-backsliding” provision, which prevents the Secretary from prescribing any amended standard that either increases the maximum allowable energy use or decreases the minimum required energy efficiency of a covered equipment. (42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(1)) Also, the Secretary may not prescribe an amended or new standard if interested persons have established by a preponderance of the evidence that the standard is likely to result in the unavailability in the United States in any covered equipment type (or class) of performance characteristics (including reliability), features, sizes, capacities, and volumes that are substantially the same as those generally available in the United States. (42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(4)) Additionally, EPCA specifies requirements when promulgating an energy conservation standard for covered equipment that has two or more subcategories. DOE must specify a different standard level for a type or class of equipment that has the same function or intended use, if DOE determines that products within such group: (A) consume a different kind of energy from that consumed by other covered equipment within such type (or class); or (B) have a capacity or other performance-related feature which other equipment within such type (or class) do not have and such feature justifies a higher or lower standard. (42 U.S.C. 6316(a); 42 U.S.C. 6295(q)(1)) In determining whether a performance-related feature justifies a different standard for a group of products, DOE must consider such factors as the utility to the consumer of the feature and other factors DOE deems appropriate. 
                    *Id.*
                     Any rule prescribing such a standard must include an explanation of the basis on which such higher or lower level was established. (42 U.S.C. 6316(a); 42 U.S.C. 6295(q)(2)) Before proposing a standard, DOE typically seeks public input on the analytical framework, models, and tools that DOE intends to use to evaluate standards for the equipment at issue and the results of preliminary analyses DOE performed for the product. DOE is examining whether to amend the current standards pursuant to its obligations under EPCA. This notification announces the availability of the preliminary TSD, which details the preliminary analyses and summarizes the preliminary results of DOE's analyses. In addition, DOE is announcing a public meeting to solicit feedback from interested parties on its analytical framework, models, and preliminary results. C. Deviation From Appendix A In accordance with section 3(a) of 10 CFR part 430, subpart C, appendix A (“appendix A”), applicable to walk-ins under 10 CFR 431.4, DOE notes that it is deviating from the provision in appendix A regarding the pre-NOPR stages for an energy conservation standards rulemaking. Section 6(a)(2) of appendix A states that if the Department determines it is appropriate to proceed with a rulemaking (after initiating the rulemaking process through an early assessment), the preliminary stages of a rulemaking to issue or amend an energy conservation standard that DOE will undertake will be a framework document and preliminary analysis, or an advance notice of proposed rulemaking (“ANOPR”). DOE is opting to deviate from this provision by publishing a preliminary analysis without a framework document. A framework document is intended to introduce and summarize the various analyses DOE conducts during the rulemaking process and requests initial feedback from interested parties. As discussed further in the following section, prior to this notification of the preliminary analysis, DOE issued an early assessment request for information on July 16, 2021 (“July 2021 RFI”) in which DOE identified and sought data, information, and comment to evaluate whether the existing energy conservation standards for walk-ins should be amended. 86 FR 37687, 37689. DOE provided a 30-day comment period for the RFI. DOE intends to rely on substantively the same analytical methods as those used in the most recent rulemakings for walk-ins, making publication of a framework document largely redundant with the July 2021 RFI. As such, DOE is not publishing a framework document. DOE notes that it is also deviating from the provision in appendix A regarding the length of comment periods for the pre-NOPR stages for an energy conservation standards rulemaking. Section 6(d)(2) of appendix A specifies that the length of the public comment period for pre-NOPR rulemaking documents will not be less than 75 calendar days. For the preliminary analysis, DOE has opted instead to provide a 60-day comment period. As stated, DOE requested comment in the July 2021 RFI on the analysis conducted in support of the last energy conservation standard rulemaking for WICFs. Given that the analysis will largely remain the same, and in light of the 30-day comment period DOE has already provided with its July 2021 RFI, DOE has determined that a 60-day comment period is sufficient to enable interested parties to review the tentative methodologies and accompanying analysis to develop meaningful comments in response to the preliminary TSD. II. Background A. Current Standards In a final rule published on June 3, 2014 (“June 2014 Final Rule”), DOE adopted the current energy conservation standards for walk-in doors, panels, and medium-temperature dedicated condensing systems manufactured on and after June 5, 2017. 79 FR 32050. In the June 2014 Final Rule, DOE also adopted standards for other classes of refrigeration systems; however, after publication of the June 2014 Final Rule, the Air-Conditioning, Heating and Refrigeration Institute (“AHRI”) and Lennox International, Inc. (“Lennox”), a manufacturer of walk-in refrigeration systems, filed petitions for review of DOE's final rule and DOE's subsequent denial of a petition for reconsideration of the rule (79 FR 59090 (October 1, 2014)) with the United States Court of Appeals for the Fifth Circuit. 
                    *Lennox Int'l*
                     v. 
                    *Dep't of Energy,*
                     Case No. 14-60535 (5th Cir.). As a result of this litigation, a settlement agreement was reached to address, and a controlling order from the Fifth Circuit vacated, standards for six of the refrigeration system equipment classes—the two energy conservation standards applicable to multiplex condensing refrigeration systems (subsequently re-named as “unit coolers”) operating at medium and low temperatures and the four energy conservation standards applicable to dedicated condensing refrigeration systems operating at low temperatures.[6]
                    
                     After the Fifth Circuit issued its order, DOE established a Working Group to negotiate energy 
                    ( print page 39012)
                    conservation standards to replace the six vacated standards. 80 FR 46521 (August 5, 2015). The Working Group assembled its recommendations into a Term Sheet (See Docket EERE-2015-BT-STD-0016-0056) that was presented to, and approved by, the Appliance Standards and Rulemaking Federal Advisory Committee (“ASRAC”) on December 18, 2015. (EERE-2015-BT-STD-0016-0055 at p. 11) In a final rule published on July 10, 2017 (“July 2017 Final Rule”), DOE published a final rule adopting current energy conservation standards for the six classes of walk-in refrigeration systems for which the prior standards were vacated—specifically, unit coolers and low-temperature dedicated condensing systems manufactured on and after July 10, 2020. 82 FR 31808. These standards are set forth in DOE's regulations at 10 CFR 431.306 and are repeated in Tables II.1 through II.3.

 B. Current Process As noted earlier, DOE published an RFI to initiate an early assessment review to determine whether any new or amended standards would satisfy the relevant requirements of EPCA for a new or amended energy conservation standard for walk-ins and to solicit relevant information from the public. 86 FR 37687. Through the RFI, DOE sought data and information to, among other things, help the agency determine whether DOE should propose a “no new standard” determination because a more stringent standard: (1) would not result in a significant savings of energy; (2) is not technologically feasible; (3) is not economically justified; or (4) any combination of foregoing. 
                    *Id.* Comments received to date as part of the current process have helped DOE identify and resolve issues related to the preliminary analyses. Chapter 2 of the preliminary TSD summarizes and addresses the comments received. III. Summary of the Analyses Performed by DOE A. Market and Technology Assessment DOE develops information in the market and technology assessment that provides an overall picture of the market for the products concerned, including general characteristics of the products, the industry structure, manufacturers, market characteristics, and technologies used in the products. This activity includes both quantitative and qualitative assessments, based primarily on publicly available information. The subjects addressed in the market and technology assessment include: (1) a determination of the scope of the rulemaking and product classes, (2) manufacturers and industry structure, (3) existing efficiency programs, (4) shipments information, (5) market and industry trends, and (6) technologies or design options that 
                    ( print page 39013)
                    could improve the energy efficiency of the product. See chapter 3 of the preliminary TSD for further discussion of the market and technology assessment. B. Screening Analysis DOE uses the following five screening criteria to determine which technology options are suitable for further consideration in an energy conservation standards rulemaking: (1) 
                    *Technological feasibility.*
                     Technologies that are not incorporated in commercial products or in working prototypes will not be considered further. (2) 
                    *Practicability to manufacture, install, and service.*
                     If it is determined that mass production and reliable installation and servicing of a technology in commercial products could not be achieved on the scale necessary to serve the relevant market at the time of the projected compliance date of the standard, then that technology will not be considered further. (3) 
                    *Impacts on product utility or product availability.*
                     If it is determined that a technology would have a significant adverse impact on the utility of the product for significant subgroups of consumers or would result in the unavailability of any covered product type with performance characteristics (including reliability), features, sizes, capacities, and volumes that are substantially the same as products generally available in the United States at the time, it will not be considered further. (4) 
                    *Adverse impacts on health or safety.*
                     If it is determined that a technology would have significant adverse impacts on health or safety, it will not be considered further. (5) 
                    *Unique-pathway proprietary technologies.*
                     If a design option utilizes proprietary technology that represents a unique pathway to achieving a given efficiency level, that technology will not be considered further due to the potential for monopolistic concerns. 10 CFR part 430, subpart C, appendix A, sections 6(b)(3) and 7(b). If DOE determines that a technology, or a combination of technologies, fails to meet one or more of the listed five criteria, it will be excluded from further consideration in the engineering analysis. See chapter 4 of the preliminary TSD for further discussion of the screening analysis. C. Engineering Analysis The purpose of the engineering analysis is to establish the relationship between the efficiency and cost of walk-ins. There are two elements to consider in the engineering analysis; the selection of efficiency levels to analyze (
                    *i.e.,*
                     the “efficiency analysis”) and the determination of equipment cost at each efficiency level (
                    *i.e.,*
                     the “cost analysis”). In determining the performance of higher-efficiency equipment, DOE considers technologies and design option combinations not eliminated by the screening analysis. For each equipment class, DOE estimates the manufacturer production cost (“MPC”) for the baseline as well as higher efficiency levels. The output of the engineering analysis is a set of cost-efficiency “curves” that are used in downstream analyses (
                    *i.e.,*
                     the LCC and PBP analyses and the NIA). DOE converts the MPC to the manufacturer selling price (“MSP”) by applying a manufacturer markup. The MSP is the price the manufacturer charges its first customer, when selling into the equipment distribution channels. The manufacturer markup accounts for manufacturer non-production costs and profit margin. DOE developed the manufacturer markup by examining publicly available financial information for manufacturers of the covered product. See Chapter 5 of the preliminary TSD for additional detail on the engineering analysis. D. Markups Analysis The markups analysis develops appropriate markups (
                    *e.g.,*
                     retailer markups, distributor markups, contractor markups) in the distribution chain and sales taxes to convert MSP estimates derived in the engineering analysis to consumer prices, which are then used in the LCC and PBP analysis. At each step in the distribution channel, companies mark up the price of the equipment to cover business costs and profit margin. DOE developed baseline and incremental markups for each agent in the distribution chain. Baseline markups are applied to the price of products with baseline efficiency, while incremental markups are applied to the difference in price between baseline and higher-efficiency models (the incremental cost increase). The incremental markup is typically less than the baseline markup and is designed to maintain similar per-unit operating profit before and after new or amended standards.[7] Chapter 6 of the preliminary TSD provides details on DOE's development of markups for walk-ins. E. Energy Use Analysis The purpose of the energy use analysis is to determine the annual energy consumption of walk-ins at different efficiencies in representative U.S. commercial buildings and to assess the energy savings potential of increased walk-in efficiency. The energy use analysis estimates the range of energy use of walk-ins in the field (
                    *i.e.,*
                     as they are actually used by consumers). The energy use analysis provides the basis for other analyses DOE performed, particularly assessments of the energy savings and the savings in consumer operating costs that could result from adoption of amended or new standards. Chapter 7 of the preliminary TSD addresses the energy use analysis. F. Life-Cycle Cost and Payback Period Analyses The effect of new or amended energy conservation standards on individual consumers usually involves a reduction in operating cost and an increase in purchase cost. DOE used the following two metrics to measure consumer impacts: The LCC is the total consumer expense of an appliance or equipment over the life of that product, consisting of total installed cost (MSP, distribution chain markups, sales tax, and installation costs) plus operating costs (expenses for energy use, maintenance, and repair). To compute the operating costs, DOE discounts future operating costs to the time of purchase and sums them over the lifetime of the product.
                The PBP is the estimated amount of time (in years) it takes consumers to recover the increased purchase cost (including installation) of a more-efficient equipment through lower operating costs. DOE calculates the PBP by dividing the change in purchase cost at higher efficiency levels by the change in annual operating cost for the year that amended or new standards are assumed to take effect. Chapter 8 of the preliminary TSD addresses the LCC and PBP analyses. G. National Impact Analysis The NIA estimates the national energy savings (“NES”) and the net present value (“NPV”) of total consumer costs and savings expected to result from amended standards at specific efficiency 
                    ( print page 39014)
                    levels (referred to as candidate standard levels).[8]
                    
                     DOE calculates the NES and NPV for the potential standard levels considered based on projections of annual equipment shipments, along with the annual energy consumption and total installed cost data from the energy use and LCC analyses. For the present analysis, DOE projected the energy savings, operating cost savings, equipment costs, and NPV of consumer benefits over the lifetime of walk-ins sold from 2027 through 2056. DOE evaluates the impacts of new or amended standards by comparing a case without such standards with standards-case projections (“no-new-standards case”). The no-new-standards case characterizes energy use and consumer costs for each equipment class in the absence of new or amended energy conservation standards. For this projection, DOE considers historical trends in efficiency and various forces that are likely to affect the mix of efficiencies over time. DOE compares the no-new-standards case with projections characterizing the market for each equipment class if DOE adopted new or amended standards at specific energy efficiency levels for that class. For each efficiency level, DOE considers how a given standard would likely affect the market shares of equipment with efficiencies greater than the standard. DOE uses a spreadsheet model to calculate the energy savings and the national consumer costs and savings from each efficiency level. Interested parties can review DOE's analyses by changing various input quantities within the spreadsheet. The NIA spreadsheet model uses typical values (as opposed to probability distributions) as inputs. Critical inputs to this analysis include shipments projections, estimated equipment lifetimes, equipment installed costs and operating costs, equipment annual energy consumption, the base case efficiency projection, and discount rates. DOE estimates a combined total of 3.647 quads of FFC energy savings at the max-tech efficiency levels for walk-in doors, panels, and refrigeration systems may result if amended standards are implemented. Chapter 10 of the preliminary TSD addresses the NIA. IV. Public Participation DOE invites public engagement in this process through participation in the webinar and submission of written comments and data. After the webinar and the closing of the comment period, DOE will consider all timely-submitted comments and additional information obtained from interested parties, as well as information obtained through further analyses. Following such consideration, the Department will publish either a determination that the standards for walk-ins need not be amended or a NOPR proposing to amend those standards. The NOPR, should one be issued, would include proposed energy conservation standards for the products covered by this rulemaking, and members of the public would be given an opportunity to submit written and oral comments on the proposed standards.

                         On March 16, 2022, the Fifth Circuit Court of Appeals (No. 22-30087) granted the Federal government's emergency motion for stay pending appeal of the February 11, 2022, preliminary injunction issued in 
                        *Louisiana*
                         v. 
                        *Biden,*
                         No. 21-cv-1074-JDC-KK (W.D. La.). As a result of the Fifth Circuit's order, the preliminary injunction is no longer in effect, pending resolution of the Federal government's appeal of that injunction or a further court order. Among other things, the preliminary injunction enjoined the defendants in that case from “adopting, employing, treating as binding, or relying upon” the interim estimates of the social cost of greenhouse gases—which were issued by the Interagency Working Group on the Social Cost of Greenhouse Gases on February 26, 2021—to monetize the benefits of reducing greenhouse gas emissions. In the absence of further intervening court orders, DOE will revert to its approach prior to the injunction and present monetized benefits where appropriate and permissible under law.

                         Because the projected price of standards-compliant products is typically higher than the price of baseline products, using the same markup for the incremental cost and the baseline cost would result in higher per-unit operating profit. While such an outcome is possible, DOE maintains that in markets that are reasonably competitive it is unlikely that standards would lead to a sustainable increase in profitability in the long run.
