Energy Conservation Program: Test 
Procedure for Refrigerated Bottled or Canned Beverage Vending Machines 
AGENCY : Office of Energy Efficiency and 
Renewable Energy, Department of Energy. 
ACTION : Notice of proposed rulemaking 
and announcement of public meeting. 
SUMMARY : The U.S. Department of 
Energy (‘‘DOE’’) proposes to amend the test procedures for refrigerated bottled or canned beverage vending machines (‘‘BVMs’’) to reference the latest version of the industry standard. DOE also proposes to provide setup instructions for non-beverage shelves, update the lowest application product temperature definition and instructions, require testing of coin and bill payment mechanisms if shipped with the BVM (but not until the compliance date of any amended energy conservation standards), specify setup instructions for leak mitigation controls, and remove an obsolete version of the test procedure. DOE is seeking comment from interested parties on the proposal. 
DATES : DOE will accept comments, data, 
and information regarding this proposal no later than May 31, 2022. See section V, ‘‘Public Participation,’’ for details. DOE will hold a webinar on Monday, May 2, 2022, from 1:00 p.m. to 4:00 p.m. See section V, ‘‘Public Participation,’’ for webinar registration information, participant instructions, and information about the capabilities available to webinar participants. If no participants register for the webinar, it will be cancelled. 
ADDRESSES : Interested persons are 
encouraged to submit comments using the Federal eRulemaking Portal at www.regulations.gov, under docket 
number EERE–2021–BT–TP–0007. Alternatively, interested persons may submit comments by email to BVM2021TP0007@ee.doe.gov. Include 
docket number EERE–2021–BT–TP– 0007 in the subject line of the message. No telefacsimiles (‘‘faxes’’) will be accepted. For detailed instructions on submitting comments and additional information on this process, see section V of this document. 
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.

1All references to EPCA in this document refer 
to the statute as amended through the Infrastructure 
Investment and Jobs Act, Public Law 117–58 (Nov. 15, 2021). 
2For editorial reasons, upon codification in the 
U.S. Code, Part B was redesignated Part A. 
3Because Congress included BVMs in Part A of 
Title III of EPCA, the consumer product provisions of Part A (rather than the industrial equipment provisions of Part A–1) apply to BVMs. DOE placed the regulatory requirements specific to BVMs in 10 CFR part 431, ‘‘Energy Efficiency Program for Certain Commercial and Industrial Equipment’’ as a matter of administrative convenience based on their type and will refer to BVMs as ‘‘equipment’’ throughout this document because of their placement in 10 CFR part 431. Despite the placement of BVMs in 10 CFR part 431, the relevant provisions of Title A of EPCA and 10 CFR part 430, which are applicable to all product types specified in Title A of EPCA, are applicable to BVMs. See 74 
FR 44914, 44917 (Aug. 31, 2009) and 80 FR 45758, 45759 (Jul. 31, 2015). The regulatory provisions of 10 CFR 430.33 and 430.34 and subparts D and E of 10 CFR part 430 are applicable to BVMs. Because the procedures in 10 CFR parts 430 and 431 for petitioning DOE for obtaining a test procedure waiver are substantively the same (79 FR 26591, 26601 (May 9, 2014)), the regulations for applying 
for a test procedure waiver for BVMs are those found at 10 CFR 431.401 rather than those found at 10 CFR 430.27. 4IEC 62301, Household electrical appliances—

I. Authority and Background 
DOE is authorized to establish and 
amend energy conservation standards 
and test procedures for Refrigerated Bottled or Canned Beverage Vending Machines (‘‘BVMs’’). (42 U.S.C. 6295(v); 42 U.S.C. 6293(b)(15)) DOE’s energy conservation standards and test procedures for Refrigerated Bottled or Canned Beverage Vending Machines (‘‘BVMs’’) are currently prescribed at subpart Q of part 431 of title 10 of the Code of Federal Regulations (‘‘CFR’’). The following sections discuss DOE’s authority to establish test procedures for BVMs and relevant background information regarding DOE’s consideration of test procedures for this product. 
A. Authority 
The Energy Policy and Conservation 
Act, as amended (‘‘EPCA’’),
1authorizes 
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 B
2of EPCA 
established the Energy Conservation Program for Consumer Products Other Than Automobiles, which sets forth a variety of provisions designed to improve energy efficiency. These products include BVMs, the subject of this document. (42 U.S.C. 6295(v))
3 The energy conservation program 
under EPCA consists essentially of four 
parts: (1) Testing, (2) labeling, (3) Federal energy conservation standards, 
and (4) certification and enforcement procedures. Relevant provisions of EPCA specifically include definitions (42 U.S.C. 6291), test procedures (42 U.S.C. 6293), labeling provisions (42 U.S.C. 6294), energy conservation standards (42 U.S.C. 6295), and the authority to require information and reports from manufacturers (42 U.S.C. 6296). 
The Federal testing requirements 
consist of test procedures that manufacturers of covered products must use as the basis for: (1) Certifying to DOE that their products comply with the applicable energy conservation standards adopted pursuant to EPCA (42 U.S.C. 6295(s)), and (2) making representations about the efficiency of those consumer products (42 U.S.C. 6293(c)). Similarly, DOE must use these test procedures to determine whether the products comply with relevant standards promulgated under EPCA. (42 U.S.C. 6295(s)) 
Federal energy efficiency 
requirements for covered products established under EPCA generally supersede State laws and regulations concerning energy conservation testing, labeling, and standards. (42 U.S.C. 6297(a)–(c)) DOE may, however, grant waivers of Federal preemption for particular State laws or regulations, in accordance with the procedures and other provisions of EPCA. (42 U.S.C. 6297(d)) 
Under 42 U.S.C. 6293, EPCA sets forth 
the criteria and procedures DOE must follow when prescribing or amending test procedures for covered products. EPCA requires that any test procedures prescribed or amended under this section be reasonably designed to produce test results which measure energy efficiency, energy use or estimated annual operating cost of a covered product during a representative average use cycle or period of use and not be unduly burdensome to conduct. (42 U.S.C. 6293(b)(3)) 
In addition, EPCA requires that DOE 
amend its test procedures for all covered products to integrate measures of standby mode and off mode energy consumption. (42 U.S.C. 6295(gg)(2)(A)) Standby mode and off mode energy consumption must be incorporated into the overall energy efficiency, energy consumption, or other energy descriptor for each covered product unless the current test procedures already account 
for and incorporate standby and off mode energy consumption or such integration is technically infeasible. If an integrated test procedure is technically infeasible, DOE must prescribe a separate standby mode and off mode energy use test procedure for the covered product, if technically feasible. (42 U.S.C. 6295(gg)(2)(A)(ii)) Any such amendment must consider the most current versions of the International Electrotechnical Commission (‘‘IEC’’) Standard 62301
4 
and IEC Standard 620875as applicable. 
(42 U.S.C. 6295(gg)(2)(A)) 
With respect to BVMs, EPCA requires 
the test procedure to be based on the 2004 version of ANSI/ASHRAE Standard 32.1, ‘‘Methods of Testing for Rating Vending Machines for Bottled, Canned or Other Sealed Beverages.’’ (42 U.S.C. 6293(b)(15)) 
EPCA also requires that, at least once 
every 7 years, DOE evaluate test procedures for each type of covered product, including BVMs, to determine whether amended test procedures would more accurately or fully comply with the requirements for the test procedures to not be unduly burdensome to conduct and be reasonably designed to produce test results that reflect energy efficiency, energy use, and estimated operating costs during a representative average use cycle. (42 U.S.C. 6293(b)(1)(A)) 
If the Secretary determines, on her 
own behalf or in response to a petition by any interested person, that a test procedure should be prescribed or amended, the Secretary shall promptly publish in the Federal Register proposed test procedures and afford interested persons an opportunity to present oral and written data, views, and arguments with respect to such procedures. The comment period on a proposed rule to amend a test procedure shall be at least 60 days and may not exceed 270 days. In prescribing or amending a test procedure, the Secretary shall take into account such information as the Secretary determines relevant to such procedure, including technological developments relating to energy use or energy efficiency of the type (or class) of covered products involved. (42 U.S.C. 6293(b)(2)) If DOE determines that test procedure revisions are not appropriate, DOE must publish its determination not to amend the test procedures. (42 U.S.C. 6293(b)(1)(A)(ii))

6As discussed further in this section, the test 
procedure at appendix B accounts for additional 
BVM operating modes not accounted for in appendix A and is mandatory for demonstrating 
compliance with the energy conservation standards in 10 CFR 431.296(b), which are required for BVMs 
manufactured on or after January 8, 2019. 
7The parenthetical reference provides a reference 
for information located in the docket of DOE’s 
rulemaking to develop test procedures for BVMs. (Docket No. EERE–2021–BT–TP–0007, which is 
maintained at www.regulations.gov). The references are arranged as follows: (commenter name, comment docket ID number, page of that 
document). DOE is publishing this notice of 
proposed rulemaking (‘‘NOPR’’) in satisfaction of the 7-year review requirement specified in EPCA. (42 U.S.C. 6293(b)(1)(A)) 
B. Background 
DOE’s existing test procedures for 
BVMs appear at 10 CFR part 431, 
subpart Q, appendix A and appendix B, both titled ‘‘Uniform Test Method for the Measurement of Energy Consumption of Refrigerated Bottled or Canned Beverage Vending Machines’’ (‘‘appendix A’’ and ‘‘appendix B’’, respectively). On or after January 8, 2019, any representations, including compliance certifications, made with respect to the energy use or efficiency of BVMs must be made in accordance with the results of testing pursuant to appendix B. 
On July 31, 2015, DOE published a 
test procedure final rule (‘‘July 2015 
Final Rule’’) that referenced updated industry test methods, improved clarity of the procedure, accounted for new equipment features, and established the test procedures at appendix A and appendix B.
680 FR 45758; See also 81 
FR 1028 (January 8, 2016). The specific 
amendments in the July 2015 Final Rule included, for both appendix A and appendix B: (1) Updating the referenced test method to ANSI/ASHRAE Standard 32.1–2010, ‘‘Methods of Testing for Rating Vending Machines for Sealed Beverages,’’ (‘‘ANSI/ASHRAE Standard 32.1–2010’’), (2) incorporating amendments to clarify several ambiguities in ANSI/ASHRAE Standard 32.1–2010, (3) eliminating the requirement to test at the 90-degree Fahrenheit (‘‘°F’’) ambient test condition, (4) clarifying the test procedure for combination vending machines, (5) clarifying the requirements for loading of BVMs under the DOE test procedure, (6) specifying the characteristics of a standard test package, (7) clarifying the average next- to-vend beverage temperature test condition, (8) specifying placement of thermocouples during the DOE test procedure, (9) establishing provisions for testing at the lowest application 
product temperature, (10) clarifying the treatment of certain accessories during 
the DOE test procedure, and (11) clarifying the certification and reporting requirements for covered BVMs. 80 FR 45758, 45760. The July 2015 Final Rule also incorporated amendments in appendix B to account for the impact of low-power modes on the measured daily energy consumption (‘‘DEC’’) of BVMs. Id. 
On May 19, 2021, DOE published in 
the Federal Register an early assessment 
request for information (‘‘May 2021 RFI’’) seeking comments on the existing DOE test procedure for BVMs. 86 FR 27054. In the May 2021 RFI, DOE requested comments, information, and data regarding a number of issues, including (1) scope and definitions, (2) test procedure setup and conditions, (3) updates to industry standards, (4) low power modes and recovery periods, (5) alternate refrigerants, (6) payment mechanisms, and (7) connected functions. 
DOE received comments in response 
to the May 2021 RFI from the interested parties listed in Table I.1.

C. Deviation From the Process Rule 
In accordance with section 3(a) of part 
430, subpart C, appendix A (‘‘Appendix A’’), DOE notes that it is deviating from the provision in appendix A regarding publication of further opportunity to comment following an early assessment RFI prior to a NOPR to amend the test procedure. Section 8(b) of appendix A; 10 CFR 431.4. DOE is opting to deviate from this step because in the May 2021 
RFI DOE already requested and received information on the topics addressed in DOE’s proposal. DOE has tentatively determined the proposals do not require an additional pre-NOPR opportunity for public comment. 
II. Synopsis of the Notice of Proposed 
Rulemaking 
In this NOPR, DOE proposes to 
update the test procedure at appendix B as follows: 
(1) Incorporate by reference the current 
industry standard ANSI/ASHRAE Standard 
32.1–2017. 
(2) Incorporate by reference the industry 
standard ANSI/AHAM HRF–1–2008 referenced in ANSI/ASHRAE Standard 32.1– 2017. 
(3) Maintain the existing DOE test 
procedure requirements that are not included in ANSI/ASHRAE Standard 32.1–2017. (4) Provide setup instructions for non- 
beverage shelves in refrigerated 
compartments. 
(5) Amend the definition of lowest 
application product temperature (‘‘LAPT’’) to 
allow for testing BVMs only capable of operating at temperatures below the specified test temperature. 
(6) Require testing of coin and bill payment 
mechanisms if shipped with the BVM (but not until the compliance date of any amended energy conservation standards). 
(7) Specify setup instructions for leak 
mitigation controls consistent with the existing test procedure instructions. 
(8) Remove the obsolete test procedure in 
appendix A. 
DOE’s proposed actions are 
summarized in Table II.1 compared to 
the current test procedure as well as the reason for the proposed change.

8As defined in 10 CFR 431.62, commercial 
refrigerator means a unit of commercial 
refrigeration equipment in which all refrigerated 
compartments in the unit are capable of operating at or above 32 °F (±2 °F). 9As provided in 10 CFR 429.134(j)(2), the 
determination of percent transparent surface does not include the surface area surrounding any compartments that are not designed to be refrigerated (as demonstrated by the presence of temperature controls), whether or not it is transparent.

DOE has tentatively determined that 
the proposed amendments described in 
section III of this NOPR would not alter the measured efficiency of BVMs or require retesting or recertification solely as a result of DOE’s adoption of the proposed amendments to the test procedures, if made final. The proposed 
amendment to require coin and bill payment mechanisms to be energized during testing would not be required until the compliance date of any amended energy conservation standards for BVMs that account for the measurement of the coin and bill payment mechanism energy, should such standards be adopted. Additionally, DOE has tentatively determined that the proposed amendments, if made final, would not increase the cost of testing. Discussion of DOE’s proposed actions are addressed in detail in section III of this NOPR. 
III. Discussion A. Scope and Definitions 
BVMs are commercial refrigerators (as 
defined at 10 CFR 431.62
8) that cool 
bottled or canned beverages and 
dispense the bottled or canned beverages on payment. 10 CFR 431.292. The defined equipment classes for BVMs include Class A, Class B, Combination A, and Combination B. 
Class A means a BVM that is not a 
combination vending machine and in which 25 percent or more of the surface area on the front side of the beverage 
vending machine is transparent. 
Class B means a BVM that is not 
considered to be Class A and is not a combination vending machine. 
Combination A means a combination 
vending machine where 25 percent or more of the surface area on the front side of the beverage vending machine is transparent.
9 
Combination B means a combination 
vending machine that is not considered 
to be Combination A. 
Combination vending machine means 
a BVM containing two or more compartments separated by a solid partition, that may or may not share a product delivery chute, in which at least one compartment is designed to be refrigerated, as demonstrated by the presence of temperature controls, and at least one compartment is not. 10 CFR 431.292. 
In the May 2021 RFI, DOE requested 
comment on several topics regarding scope and definitions. 86 FR 27054, 27056. DOE requested comment on whether it should define ‘‘dispense’’ to better differentiate between BVMs and other commercial refrigerators as defined in 10 CFR 431.62. Id. DOE also 
requested comment on the distinction between refrigerated and non- refrigerated compartments and whether the term ‘‘solid partition’’ in the definition of combination vending machines needs further specificity. Id. Regarding equipment classes, DOE requested comment on whether any additional clarifications are needed for the existing BVM equipment class definitions, or if there are any categories within the current classes that would require additional test provisions. Id. 
DOE received no comment on these 
issues in response to the May 2021 RFI. Additionally, DOE has not identified BVMs available on the market that would require additional specificity in the existing BVM definitions. Therefore, DOE has tentatively determined that amendments are not required and is not proposing any new or amended BVM definitions in this NOPR. 
B. Updates to Industry Standards 
DOE’s BVM test procedure in 
appendix B incorporates by reference 
ANSI/ASHRAE Standard 32.1–2010, which was the most current version of the industry standard available at the time of the July 2015 Final Rule. 80 FR 45758, 45762. DOE specifically references section 3, ‘‘Definitions’’; section 4, ‘‘Instruments’’; section 5, ‘‘Vendible Capacity’’; section 6, ‘‘Test Conditions’’; section 7.1, ‘‘Test Procedures—General Requirements’’; and section 7.2, ‘‘Energy Consumption Test’’ of ANSI/ASHRAE Standard 32.1– 2010. Appendix B includes certain exceptions to these references, and in cases of conflict between appendix B language and the requirements of ANSI/ ASHRAE Standard 32.1–2010, the language in appendix B takes precedence. See section 1 of appendix B.

At the time of the July 2015 Final 
Rule analysis, DOE was aware of 
ongoing industry meetings to consider updates to ASHRAE Standard 32.1. DOE participated in those industry meetings and, to the extent possible, sought to align its test procedure with the expected updates to ASHRAE 32.1. 80 FR 45758, 45762. 
On February 2, 2017, ANSI and 
ASHRAE approved the latest version of Standard 32.1, ANSI/ASHRAE 32.1– 2017, ‘‘Methods of Testing for Rating Vending Machines for Sealed Beverages,’’ (‘‘ANSI/ASHRAE Standard 32.1–2017’’). 
Many of the revisions included in 
ANSI/ASHRAE Standard 32.1–2017 harmonize the industry standard with the existing DOE test procedure. However, some substantive differences between DOE’s test procedure at appendix B and ANSI/ASHRAE Standard 32.1–2017 remain, notably the following: 
(1) Section 2.2.4 of appendix B 
contains provisions for testing accessory low power mode, and section 2.3.2 of appendix B accounts for refrigeration low power mode; whereas ANSI/ ASHRAE Standard 32.1–2017 contains no such provisions (and specifically prohibits operation in low-power mode during testing, per section 7.2.2.6.2). See section III.B.6 of this NOPR for additional discussion of low power 
modes. 
(2) Section 2.1.3 of appendix B 
provides instructions for testing BVMs that are not capable of maintaining an integrated average temperature of 36 °F 
± 1°F during the 24-hour test period; 
whereas ANSI/ASHRAE Standard 32.1– 2017 contains no such provisions. See section II.B.4 of this NOPR for additional discussion of lowest application product temperatures. 
(3) Section 2.2.1.4 of appendix B 
specifies a ‘‘standard product’’ consisting of standard 12-ounce aluminum beverage cans filled with a liquid with a density of 1.0 grams per milliliter (‘‘g/mL’’) ± 0.1 g/mL at 36 °F; 
whereas ANSI/ASHRAE Standard 32.1– 2017 specifies using a 33 percent propylene glycol and 67 percent water solution. See section II.B.3 for additional discussion of standard product characteristics. 
(4) Section 2.2.5.1 of appendix B 
provides instructions for payment mechanisms that cannot be disconnected during testing (if the payment mechanism is not removed, appendix B requires it to be in place but de-energized, or set to the lowest energy consuming state if it cannot be de- energized) and specifies a default payment mechanism energy consumption of 0.20 kWh/day; whereas ANSI/ASHRAE Standard 32.1–2017 contains no such provisions. See section II.B.5 for additional discussion of payment mechanisms. 
(5) Section 2.2.3 of appendix B 
requires energy management systems to be disabled and energy-saving features that cannot be disabled to be set to their most energy-consuming settings; whereas ANSI/ASHRAE Standard 32.1– 2017 also requires that energy management systems be disabled, but does not address other energy-saving features that cannot be disabled. 
(6) Sections 2.2.5.2 through 2.2.5.10 of 
appendix B provide additional setup instructions regarding certain equipment accessories (i.e., internal 
lighting; external customer display signs, lights, and digital screens; anti- sweat or other electric resistance heaters; condensate pan heaters and pumps; illuminated temperature displays; condensate filters; security covers; general purpose outlets; and crankcase heaters and other electric resistance heaters for cold weather); whereas ANSI/ASHRAE Standard 32.1– 2017 provides instructions for only a subset of these accessories (i.e., video 
screens and lighting). 
(7) Section 2.2.2 of appendix B 
prohibits routing thermocouple wires and other measuring equipment through the dispensing door; whereas ANSI/ ASHRAE Standard 32.1–2017 contains no such prohibition (only that they be installed in a manner that does not affect energy performance). 
(8) Section 2.3.3 of appendix B 
provides rounding instructions on energy consumption results; whereas ANSI/ASHRAE Standard 32.1–2017 contains no such rounding instructions. 
(9) ANSI/ASHRAE Standard 32.1– 
2017 provides an additional recovery test (to determine the product temperature recovery time of the BVM when loaded with product at a certain temperature) and a vend test (to determine how much cold product a BVM will deliver when bottles, cans, or other sealed packages are vended at a rate of two per minute, 3 hours after a half-full machine is refilled with product at a specified beverage temperature); whereas appendix B contains no such tests. These tests assess product temperature recovery and vending performance but do not factor into the energy use measurement in ANSI/ASHRAE Standard 32.1–2017. 
In addition to the differences with the 
DOE test procedure, ANSI/ASHRAE Standard 32.1–2017 also lists key changes from the 2010 version, summarized by the following: •Updates definitions to specify the 
application to BVMs; 
•Removes zone-cooled/fully cooled 
distinction; 
•Updates AHAM HRF–1 reference to 
a more recent version of the standard (2008); 
•Removes the 90 °F test condition for 
ambient temperature and maintains a single ambient temperature (75 °F); 
•Clarifies test setup requirements for 
temperature sensor locations and test package/wire setup; 
•Incorporates requirements for the 
controls systems; and 
•Clarifies the integrated average 
temperature (‘‘IAT’’) calculation. 
In the May 2021 RFI, DOE requested 
comment on whether it should update its test procedure to incorporate by reference ANSI/ASHRAE Standard 32.1–2017 and whether any of the updates included would affect measured energy consumption. 86 FR 27054, 27057. Additionally, DOE requested comment on the differences between the current DOE test procedure and ANSI/ASHRAE Standard 32.1– 2017, and whether there are any known deficiencies in ANSI/ASHRAE Standard 32.1–2017 that DOE should consider addressing in the future. Id. 
ASAP and NRDC and the CA IOUs 
commented in support of updating the current DOE test procedure to incorporate by reference ANSI/ASHRAE Standard 32.1–2017. (ASAP and NRDC, No. 4, p.1; CA IOUs, No. 6, p.2) 
ASAP and NRDC, NEEA and NPCC, 
and the CA IOUs recommended that DOE maintain provisions for low power mode testing, which are not included in ANSI/ASHRAE Standard 32.1–2017. (ASAP and NRDC, No. 4, p. 1; NEEA and NPCC, No.7, p.3; CA IOUs No. 6, p.2) ASAP and NRDC commented that these test provisions can incentivize manufacturers to incorporate more energy management controls to reduce energy consumption. (ASAP and NRDC, No. 4, p.1) ASAP and NRDC also commented that DOE should maintain the current test procedure provision to address energy saving features that cannot be disabled, which is not included in ANSI/ASHRAE Standard 32.1–2017, to help maintain consistency for testing across different machines. (ASAP and NRDC, No. 4, p. 2) NEEA and NPCC further recommended that DOE should maintain the requirement that energy saving features be enabled during testing. (NEEA and NPCC, No.7 p.3) 
ASAP and NRDC, as well as NEEA 
and NPCC, recommended that DOE should continue to account for payment mechanism energy consumption, which is not included in ANSI/ASHRAE

No. 4, p.2; NEEA and NPCC, No. 7, p. 3) 
Additionally, ASAP and NRDC, as 
well as NEEA and NPCC, supported maintaining existing accessory equipment setup instructions not included in ANSI/ASHRAE Standard 32.1–2017 to help provide clarity for lab technicians and consistency across test labs. (ASAP and NRDC, No. 4, p. 2; NEEA and NPCC, No. 7, p.3) 
ASAP and NRDC, as well as NEEA 
and NPCC, also recommend maintaining the rounding instructions currently in the DOE test procedure (for energy consumption results) because ASHRAE Standard 32.1–2017 does not contain such instructions. (ASAP and NRDC, No. 4, p. 2; NEEA and NPCC, No. 7, p.3) 
The CA IOUs also commented that 
they believe the ANSI/ASHRAE Standard 32.1–2017 specifications on contents of the test containers will result in higher reproducibility and should be adopted for the DOE test procedure. (CA IOUs, No. 6, p. 2) 
DOE considered the comments 
received in response to the May 2021 RFI and proposes to incorporate by reference the most recent updated industry standard ANSI/ASHRAE Standard 32.1–2017, while maintaining the current DOE test procedure provisions not included in ANSI/ ASHRAE Standard 32.1–2017 regarding energy management systems, accessory 
setup instructions, wire routing, and rounding. This proposed approach is consistent with the recommendations from interested parties. DOE has tentatively determined that this proposal would not impact current BVM ratings or test costs because the proposed test procedure is substantively the same as the current DOE test procedure. 
The other topics raised in comments 
from interested parties or noted as differences between ANSI/ASHRAE Standard 32.1–2017 and the current DOE test procedure (i.e., characteristics 
of the standard product, lowest application product temperature, payment mechanisms, low-power modes, and additional operating modes) are discussed in detail in subsequent sections of this NOPR. 
As discussed earlier in this section, 
Appendix C of ANSI/ASHRAE Standard 32.1–2017 refers to the 2008 version of ANSI/AHAM Standard HRF–1 ‘‘Energy, Performance and Capacity of Household Refrigerators, Refrigerator-Freezers and Freezers’’ (‘‘ANSI/AHAM HRF–1– 2008’’) for measuring the refrigerated volume of BVMs. The current DOE test procedure, by reference to ANSI/ ASHRAE Standard 32.1–2010, refers to the 2004 version of ANSI/AHAM 
Standard HRF–1 (‘‘ANSI/AHAM HRF– 1–2004’’) for measuring BVM refrigerated volume. For consistency with the proposed incorporation by reference of ANSI/ASHRAE Standard 32.1–2017, DOE is also proposing to incorporate by reference ANSI/AHAM HRF–1–2008 to ensure that BVM testing is conducted to the appropriate test standard. DOE has determined that the updates made to ANSI/AHAM HRF–1 between the 2004 and 2008 versions provide clarifications and instructions for measuring components that are specific to consumer refrigeration products (e.g., consideration of through- 
the-door ice and water dispensers) and that current refrigerated volume measurements and ratings for BVMs would be unchanged under the proposed updated industry standard reference. 
DOE requests comment on its 
proposal to incorporate by reference the most current industry test standard, ANSI/ASHRAE Standard 32.1–2017, including the updated reference to ANSI/AHAM HRF–1–2008 for measuring refrigerated volume. Specifically, DOE requests comment on whether the proposed amendments would affect BVM ratings as measured under the existing test procedure or 
whether they would impact test burden. 
C. Test Procedure 
In the May 2021 RFI, DOE specifically 
asked for comment on the following 
topics: Ambient test conditions, test procedure for combination BVMs, characteristics of the standard product, lowest application product temperature, payment mechanisms, low power modes, reloading and recovery periods, alternate refrigerants, and connected functions. 86 FR 27054, 27057–27061. The following sections summarize the comments received on these topics DOE’s responses, and any corresponding proposed amendments to the DOE test procedure. 
1. Ambient Test Conditions 
Section 2.1.2 of appendix B requires 
testing and rating BVM performance in 
a 75 °F ambient temperature with a 45 
percent relative humidity. Prior to the July 2015 Final Rule, the DOE test procedure incorporated by reference ANSI/ASHRAE Standard 32.1–2004, which included two ambient test conditions: 75 °F with a 45 percent 
relative humidity and 90 °F with a 65 
percent relative humidity. However, compliance with DOE’s energy conservation standard was determined based on performance at only the 75 °F 
with a 45 percent relative humidity test condition. In the July 2015 Final Rule, 
DOE determined that the 75 °F with a 45 
percent relative humidity test condition provides a reasonable and comparable representation of energy performance for all BVMs and removed the 90 °F 
with a 65 percent relative humidity condition. 80 FR 45758, 45765. 
During the rulemaking leading to the 
July 2015 Final Rule, DOE estimated that 18 percent of Class B and Combination B BVMs are installed outdoors. 80 FR 45758, 45765. DOE determined that, although these BVMs would experience different ambient conditions than in the test procedure, it would not be feasible to test at all the conditions BVMs may experience in the field. Id. In ANSI/ASHRAE Standard 
32.1–2017, the 90 °F with a 65 percent 
relative humidity test condition for the energy consumption test was removed, and the industry test standard designated the 75 °F with a 45 percent 
relative humidity test condition as the singular test condition. 
If certain BVMs are specifically 
designed to operate in unique ambient conditions (i.e., are intended for use 
only in the unique condition and are not optionally installed indoors, as are most 
BVMs), testing at a different ambient condition may better represent average energy use in the field. 
In the May 2021 RFI, DOE requested 
comment on the number of BVMs that operate outdoors or in other unique environments that might differ from the single specified test condition. 86 FR 27054, 27058. DOE also requested information on how to identify and define outdoor BVMs, appropriate test methods to represent their energy consumption, and the costs associated with those methods. Id. 
DOE did not receive any comments on 
these topics in response to the May 2021 RFI. While acknowledging that BVMs may be installed and operated in a variety of locations and ambient conditions, DOE has tentatively determined that the existing single test condition provides a representative test condition for BVMs, consistent with the July 2015 Final Rule determination. DOE does not propose any changes to the current requirement to test under the single ambient test condition (75 °F 
and 45 percent relative humidity), consistent with the test condition specified in ASHRAE Standard 32.1– 2017. 
2. Test Procedure for Combination 
BVMs 
As described in section III.A, DOE 
defines ‘‘combination BVM’’ as a BVM containing two or more compartments separated by a solid partition, that may 
VerDate Sep<11>2014 19:31 Mar 30, 2022 Jkt 256001 PO 00000 Frm 00007 Fmt 4701 Sfmt 4702 E:\FR\FM\31MRP2.SGM 31MRP2jspears on DSK121TN23PROD with PROPOSALS218942 Federal Register / Vol. 87, No. 62 / Thursday, March 31, 2022 / Proposed Rules 
or may not share a product delivery 
chute, in which at least one compartment is designed to be refrigerated, as demonstrated by the presence of temperature controls, and at least one compartment is not. 10 CFR 431.292. The thermal mass of items loaded into the non-refrigerated compartments (or lack of thermal mass for unloaded compartments) may affect the measured DEC of combination BVMs. Section 2.2.1.3 of appendix B specifies that the non-refrigerated compartments of combination BVMs must not be loaded with any standard products or other vendible merchandise during testing. Sections 7.2.2.2 and 7.2.2.7 of ANSI/ASHRAE Standard 32.1–2017 require combination BVMs not to be loaded with any standard products, test packages, or other vendible merchandise in the non- refrigerated compartments. 
The thermal mass of items loaded into 
the non-refrigerated compartments (or lack of thermal mass for unloaded compartments) may affect the measured DEC of combination BVMs. In the May 2021 RFI, DOE sought feedback on whether requiring some load in the non- refrigerated compartment would better represent the average energy use of combination BVMs. 86 FR 27054, 27058. DOE also requested comment on the typical thermal mass of merchandise loaded into the non-refrigerated compartments of combination BVMs and the potential impact of such a load on tested energy consumption. Id. 
ASAP and NRDC encouraged DOE to 
consider requiring a load in the non- refrigerated compartments, after investigating the typical thermal mass loaded, to provide a more representative energy consumption measurement. (ASAP and NRDC, No. 4, p. 2) 
DOE did not receive comments in 
response to the May 2021 RFI regarding the typical thermal mass of loads in the non-refrigerated compartments on combination BVMs. Based on a review of the market, typical loads for non- refrigerated compartments can range from small items with density similar to beverages (e.g., chocolate bars), to larger 
low-density items (e.g., bags of chips). 
Given the wide range of products stored in non-refrigerated compartments, DOE has not identified a typical representative load for these 
compartments. Additionally, DOE acknowledges that loading non- refrigerated compartments in a consistent, repeatable manner may be difficult due to the range of shelf configurations in those compartments. DOE did not identify a standard package that could be consistently loaded into non-refrigerated shelves for testing. Requiring such a load would introduce 
additional test burden compared to the existing unloaded approach. 
DOE has tentatively determined that 
the current test procedure provides a representative, repeatable, and reproducible approach for testing combination BVMs while minimizing test burden. Accordingly, DOE is not proposing to require a load in non- refrigerated compartments. 
DOE continues to request information 
on typical loads for non-refrigerated compartments in combination BVMs and, if DOE were to require such loads for testing, the potential impacts on combination BVM energy consumption and test burden. 
3. Characteristics of the Standard 
Product 
Section 2.2.1.4 of appendix B 
specifies the standard products to be used for testing, which include the following: 12-ounce aluminum beverage cans filled with a liquid with a density of 1.0 grams per milliliter (‘‘g/mL’’) ±0.1 g/mL at 36 °F; or, for product storage 
racks that are not capable of vending 12- ounce cans, but are capable of vending 20-ounce bottles, 20-ounce plastic bottles filled with a liquid with a density of 1.0 g/mL ±0.1 g/mL at 36 °F; 
or, for product storage racks that are not 
capable of vending 12-ounce cans or 20- ounce bottles, the packaging and contents specified by the manufacturer in product literature as the standard product (i.e., the specific merchandise 
the refrigerated bottled or canned beverage vending machine is designed to vend). 
In the July 2015 Final Rule, DOE 
discussed the possibility of considering other standard products, including slimline cans, milk cartons, aseptic packs, pouches, and energy drinks. 80 FR 45758, 45768. These potential alternative standard products all hold liquids and otherwise would allow for testing following the current BVM test procedure instructions. However, DOE determined that the standard product for BVMs not capable of vending 12- ounce cans or 20-ounce bottles is the product specified by the manufacturer in product literature. Id. 
In the May 2021 RFI, DOE requested 
comment on whether the standard products as currently defined (i.e., the 
products comprising the BVM test load) are representative of average BVM use and if any additional products should be defined as standard products to limit variability in testing. 86 FR 27054, 27058. Additionally, DOE requested detailed descriptions of any such products and what the appropriate method of loading would be for BVMs designed to dispense merchandise other 
than the standard products. 86 FR 27054, 27058–27059. 
DOE did not receive comment on 
these topics in response to the May 2021 RFI and proposes to maintain the current test procedure standard packages of 12-ounce cans, 20-ounce bottles, or the packaging and contents specified by the manufacturer in product literature, depending on the BVM vending capability. 
Additionally, DOE stated in the May 
2021 RFI that certain BVMs are marketed to vend both beverages and food, but do not contain a solid partition that separates the shelves or compartments intended for refrigerated bottled or canned beverages from those intended for other merchandise. 86 FR 27054, 27058. If the non-beverage shelves of these BVMs are not capable of vending 12-ounce cans or 20-ounce bottles, the standard product for testing is the packaging and contents specified by the manufacturer in product literature as the standard product per section 2.2.1.4 of appendix B. Id. 
For non-beverage shelves, 
manufacturers do not always specify the packaging and contents of the merchandise to be loaded. Additionally, measuring temperature at the center of mass of non-liquid merchandise packaging would provide unique challenges compared to liquid containers (e.g., measuring the center of 
mass of a bag of chips). 
Similar to the discussion regarding 
non-refrigerated compartments in combination BVMs in section III.C.2 of this document, DOE has tentatively determined that it cannot identify a representative non-beverage test load because of the wide range of merchandise that could be loaded in non-beverage shelves. Additionally, DOE expects that measuring the temperatures of non-beverage standard packages would be difficult to do repeatably and reproducibly (i.e., measuring the temperature in food packaging rather than in a liquid) and 
would increase test burden. To ensure that BVMs with non-beverage merchandising shelves are tested consistently and in a representative manner while limiting test burden, DOE is proposing to specify in a new section 2.2.1.1 of appendix B that shelves within the refrigerated compartment that are only for non-beverage merchandise must not be loaded for testing. DOE expects that manufacturers may already use this approach for testing shelves that cannot accommodate any beverage containers (i.e., it is unclear how manufacturers 
currently test such BVMs, and DOE has

which incorporates by reference ANSI/ASHRAE 
Standard 72–2005, (‘‘ANSI/ASHRAE 72–2005’’), ‘‘Method of Testing Commercial Refrigerators and Freezers.’’ Section 6.2.1 of ANSI/ASHRAE 72–2005 specifies the use of propylene glycol solution in test simulators.

certification-data. not received petitions for waiver 
regarding this issue). DOE similarly does not expect that this proposal would result in any cost impacts for BVM manufacturers. 
DOE requests comment on the 
proposal to specify that non-beverage merchandise shelves not be loaded for testing BVMs. DOE seeks information on how such models are currently tested and on whether this proposal would impact current BVM ratings or test burden. 
As discussed in section III.B, section 
2.2.1.4 of appendix B requires that the standard product 12-ounce cans or 20- ounce bottles be filled with liquid with a density of 1.0 grams per milliliter (‘‘g/ mL’’) ± 0.1 g/mL at 36 °F. Whereas, 
ANSI/ASHRAE Standard 32.1–2017 requires the beverage temperature test packages to be filled with a 33 percent propylene glycol and 67 percent water solution. ANSI/ASHRAE Standard 32.1– 2017 does not specify whether these glycol and water percentages are based 
on weight or volume. In the May 2021 RFI, DOE requested comment on whether the standard products defined in appendix B require any further specifications. 86 FR 27054, 27059. DOE requested feedback on whether it should specify the contents of the test containers (e.g., the 33 percent 
propylene glycol and 67 percent water solution, and whether these percentages are based on weight or volume) as specified in ANSI/ASHRAE Standard 32.1–2017. Id. 
The CA IOUs commented that they 
believe the ANSI/ASHRAE Standard 32.1–2017 specifications for test container contents would result in higher reproducibility and should be adopted for the DOE test procedure. (CA IOUs, No. 6, p. 2) 
DOE specifies the use of a propylene 
glycol solution in other test procedures, such as for testing commercial refrigeration equipment.
10Commercial 
freezers are by definition capable of operating below 32 °F (see 10 CFR 
431.62) and are tested at a 0 °F 
integrated average temperature. See section 2.1 of 10 CFR part 431, subpart C, appendix B. While water would freeze at operating temperatures below 32°F, the propylene glycol solution has 
a reduced freezing point and remains a liquid at the test temperatures. The potential for a phase change in the test solution introduces test variability as solid and liquid water have different 
heat transfer properties, and if the phase change occurs during a test, the measured temperature during the phase change may not represent actual storage temperatures. 
For BVMs, the target test condition of 
36°F is above the freezing point of water 
and other liquids likely to be used for testing BVMs. As a result, DOE has tentatively determined that specifying an alternative propylene glycol solution for testing BVMs is not likely to reduce 
test variability as is the case when testing other types of equipment at temperatures below the freezing point of water. Additionally, requiring the use of a propylene glycol solution would increase test burden compared to the existing test approach, which allows more flexibility and does not require the preparation of a test solution. For these reasons, DOE is not proposing to amend the existing test procedure provisions regarding the specifications of the standard product. 
4. Lowest Application Product 
Temperature 
Section 2.1.1 of appendix B requires 
that the integrated average temperature (‘‘IAT’’) of the BVM be 36 °F ± 1°F over 
the test period. See table B.1 of 
appendix B. For BVMs only capable of operating at temperatures higher than the specified IAT of 36 °F ± 1°F, section 
2.1.3 of appendix B requires testing at the BVM’s lowest application product temperature (‘‘LAPT’’). 
DOE’s compliance certification 
database
11lists all BVM models 
certified to DOE, including the LAPT used for rating each model, if applicable. Of the 153 individual models included in the compliance certification database at the time of this analysis, 9 individual models (representing 3 basic models) from one manufacturer are rated at LAPTs ranging from 37.9 °F to 41.3 °F. Additional 
models had previously been certified to DOE (but are not included in the current DOE compliance certification database) as being rated at a LAPT below the 36 °F 
± 1°F IAT range required in the DOE 
test procedure. For example, models from one manufacturer were previously rated at an IAT of 32 °F, indicating that 
those BVMs could not operate at 36 °F 
± 1°F. 
In the May 2021 RFI, DOE requested 
comment on whether the LAPT provisions are appropriate for testing BVMs not capable of maintaining an IAT of 36 °F ± 1°F. 86 FR 27054, 27059. 
DOE further requested comment on whether appendix B should include additional instructions for testing BVMs only capable of maintaining temperatures below the specified 36 °F ± 
1°F. Id. 
In response to the May 2021 RFI, the 
CA IOUs recommended that DOE require BVMs to operate during testing at or below the standard temperature in ANSI/ASHRAE Standard 32.1–2017 to ensure that all BVMs are tested consistently, instead of the current test procedure, which allows for testing at the lowest application product temperature. (CA IOUs, No. 6, p. 2) 
DOE acknowledges that the LAPT 
provisions result in some BVMs being tested at a higher temperature than those capable of maintaining the required test IAT. However, for BVMs not capable of operating with temperatures of 36 °F ± 1°F, the LAPT 
test provisions are representative of the actual operation of those models. Accordingly, the LAPT test provisions measure the energy use of those BVMs during a representative average use cycle or period of use as required by EPCA. (42 U.S.C. 6293(b)(3)) Additionally, any models tested and rated under the LAPT provisions are identified in DOE’s compliance certification database, along with the actual IAT maintained during testing for those models, so that such information is available to customers making purchasing decisions. 
DOE is proposing to maintain the 
current LAPT provisions and add an additional provision for testing BVMs that are only capable of maintaining temperatures below the 36 °F ± 1°F 
range. For these units, DOE proposes to test at the highest thermostat setting. This would allow for testing the BVM under the setting closest to the required IAT. DOE proposes to amend the definition of LAPT in section 1.2 of appendix B to the following: 
‘‘Lowest application product temperature’’ 
means the following: 
(a) For units that operate only at 
temperatures above the integrated average 
temperature specified in Table 1 of ANSI/ ASHRAE Standard 32.1–2017: The lowest integrated average temperature a given basic model is capable of maintaining so as to comply with the temperature stabilization requirements specified in Section 7.2.2.2 of ANSI/ASHRAE Standard 32.1–2017. 
(b) For units that operate only at 
temperatures below the integrated average temperature specified in Table 1 of ANSI/ ASHRAE Standard 32.1–2017: The highest integrated average temperature a given basic model is capable of maintaining so as to comply with the temperature stabilization requirements specified in Section 7.2.2.2 of ANSI/ASHRAE Standard 32.1–2017.

DOE has tentatively determined that 
this proposal would not affect current 
BVM ratings or testing costs because DOE has not identified any BVMs currently available on the market that would be tested under the newly proposed provision addressing units that operate only at temperatures below the IAT of 36 °F ± 1°F. 
DOE requests comment on its initial 
determination to maintain the existing LAPT approach for units that operate only at temperatures above the IAT of 36°F ± 1°F. DOE requests comment on 
its proposal to require testing at the highest integrated average temperature a given basic model is capable of maintaining for units that are only capable of operating at temperatures below the specified IAT of 36 °F ± 1°F. 
5. Payment Mechanisms 
Section 2.2.5.1 of appendix B requires 
testing BVMs with no payment mechanism in place, the payment mechanism in-place but de-energized, or the payment mechanism in place but set to the lowest energy consuming state, if it cannot be de-energized. A default payment mechanism energy consumption value of 0.20 kilowatt- hours per day (‘‘kWh/day’’) is added to the measured energy consumption, according to section 2.3 of appendix B. In Section 7.1.2.2. of ANSI/ASHRAE Standard 32.1–2017, payment mechanisms are required to be disconnected during testing. 
In the July 2015 Final Rule, DOE 
determined that because payment 
mechanisms are variable and are not always included in the machine at the time of sale, it is difficult to unambiguously specify a ‘‘representative’’ payment mechanism or device combination. 80 FR 45758, 45776. DOE concluded that conducting physical testing of BVMs with no payment mechanisms installed, as opposed to testing with the payment 
mechanisms in place, is the most straightforward, repeatable, and unambiguous approach. Id. Because 
payment mechanisms are integral to the vending function of BVMs, DOE established the 0.20 kWh/day value based on a weighted average energy consumption of 25 different payment mechanisms available at the time of the July 2015 Final Rule, which included 11 coin mechanisms, 11 bill validators, and 3 credit card readers. 80 FR 45758, 45777. 
Since the publication of the July 2015 
Final Rule, the prevalence of different payment mechanisms for BVMs may have shifted. For example, credit card readers may be more common in the field compared to coin mechanisms or bill validators, or BVMs may incorporate multiple types of payment mechanisms. Based on the July 2015 Final Rule data, credit card readers had the highest idle mode power consumption. 80 FR 45758, 45777. If such a shift has occurred in the market, an amended payment mechanism energy adder may provide results that are more representative of average energy use. Alternatively, a direct test of energy consumption rather than a fixed energy use adder may be more representative of average energy use. 
In the May 2021 RFI, DOE requested 
comment on whether BVMs are typically sold with payment mechanisms in place. 86 FR 27054, 27059. If not, DOE requested information on the types of payment mechanisms typically installed on 
BVMs and their associated energy use. Id. 
DOE did not receive any feedback on 
whether BVMs are typically sold with payment mechanisms. 
Based on a survey of units currently 
available on the market, DOE has observed that coin and bill payment mechanisms are typically included with 
BVMs as sold or shipped, but that credit card readers are typically sold as an optional feature and are sold separately from the BVM. DOE does not have data regarding the relative use of credit card readers as compared to coin and bill payment mechanisms. 
In the May 2021 RFI, DOE 
additionally requested feedback on whether the current 0.20 kWh/day energy use assigned to payment mechanisms is representative of the current BVM market. 86 FR 27054, 27059. 
ASAP and NRDC commented that 0.2 
kWh/day may not be representative of the current market and that in the case of a BVM shipped without a payment mechanism, it would make sense to specify a default value that represents the most energy-consuming payment mechanism. (ASAP and NRDC, No. 4, p. 2) ASAP and NRDC, as well as the CA IOUs, commented that DOE should include a direct test of the energy use of payment mechanisms in the test procedure, stating that individual payment mechanism energy use can vary significantly and may depend on integrated ‘‘smart functionality.’’ (ASAP and NRDC, No. 4, p. 2; CA IOUs No. 6, p.3) 
DOE conducted a review of currently 
available payment mechanisms to determine whether the previously derived 0.20 kWh/day default payment mechanism energy consumption is 
appropriate. DOE reviewed manufacturer specifications for 3 coin changers, more than 30 bill validators, and 2 credit card readers. A summary of the calculated daily energy consumptions for each payment mechanism type based on the manufacturer specifications is presented in Table III.1.

As stated, DOE has observed that coin 
and bill payment mechanisms are 
typically included with BVMs as shipped, and that credit card readers are an additional accessory provided by the manufacturer as an option or sold separately. DOE has tentatively determined that requiring a payment mechanism that is included with a BVM as shipped (i.e., the coin and bill 
payment mechanism) to be energized during testing would provide a more representative measure of energy use compared to the current default value specified in the test procedure. DOE is proposing to amend the test procedure to require that if a BVM is shipped with coin and/or bill payment mechanisms in place, the payment mechanisms shall be energized during testing. Because credit card readers are more likely to be

12‘‘Low power mode’’ means a state in which a 
beverage vending machine’s lighting, refrigeration, 
and/or other energy-using systems are automatically adjusted (without user intervention) such that they consume less energy than they consume in an active vending environment. Section 1.2, appendix B. optional features or sold separately, 
DOE is proposing to maintain the existing approach in which credit card payment mechanisms would be disconnected or de-energized, if possible, or in place but set to the lowest energy consuming state, if it cannot be de-energized, for testing. 
To account for the possibility that a 
BVM may be shipped with no payment mechanism in place, DOE is proposing to maintain the 0.20 kWh/day energy use adder to represent the energy consumption of a payment mechanism during representative use. Based on the identified payment mechanism energy use data, 0.20 kWh/day is near the average energy use of a coin changer plus a bill validator, which DOE observed is the typical default payment mechanism setup. DOE is not proposing an energy use adder based on the most energy-consuming payment mechanisms, as recommended by ASAP and NRDC, to ensure that the energy consumption as measured from testing reflects operation during a representative average use cycle or period of use. 
Because the proposal to test BVMs 
with energized coin and bill payment mechanisms, when included with a BVM as shipped, would likely affect existing BVM energy use ratings, DOE is proposing that these particular amendments would not be required for use until the compliance date of any future amended energy conservation standards for BVMs, should such standards be adopted. As such, DOE has tentatively determined that manufacturers would not be required to re-test or re-certify BVMs as a result of the proposed payment mechanism approach. DOE has also tentatively determined that manufacturers would incur no additional costs related to this proposal. On the compliance date of any amended energy conservation standards for BVMs, should such standards be adopted, this proposal would only require re-testing for any BVMs shipped with coin or bill payment mechanisms in place. For all other BVMs, the existing test procedure approach would remain unchanged. 
DOE requests comment on its 
proposal to require testing with coin and bill payment mechanisms energized, if they are included in the 
BVM as shipped. DOE requests comment on whether this approach would result in any additional test burden. DOE additionally requests comment on its proposal to require that any credit card payment mechanisms be disconnected or de-energized, if possible, or in place but set to the lowest energy consuming state, if they cannot be de-energized, for testing. DOE 
further requests information on the continued use of the 0.20 kWh/day energy use adder for BVMs shipped 
with no coin or bill payment mechanisms in place. DOE also requests comment on the proposal to not require the use of these amendments until the compliance date of any future amended energy conservation standards for BVMs. 
6. Low Power Modes 
Appendix B incorporates definitions 
and test requirements for two types of 
low power modes
12(i.e., accessory low 
power mode and refrigeration low power mode). Section 7.2.2.6.2 of ANSI/ ASHRAE Standard 32.1–2017 requires that low power modes not be allowed to operate during testing. 
In the July 2015 Final Rule, DOE 
acknowledged that the two types of low power modes incorporated into the test procedure may not address all forms of low power modes available in the BVM market. 80 FR 45758, 45786. DOE identified ‘‘learning-based’’ energy management controls that use historic sales and traffic data to predict times of high and low traffic; however, DOE did not propose a test procedure for such controls, determining that it would be difficult to develop a repeatable test procedure to evaluate the energy savings of such controls during a 24-hour test in a laboratory. Id. 
In the May 2021 RFI, DOE requested 
comment on the availability of additional low power modes, including any ‘‘learning-based’’ energy management controls, and on whether such modes should be included in the test procedure. 86 FR 27054, 27060. 
NEEA and NPCC recommended that 
DOE consider the energy benefits of ‘‘learning-based’’ energy management controls and include them in the test procedure. NEEA and NPCC noted that while energy savings from these technologies is still unknown, their research shows a trend in this technology being implemented into BVMs. NEEA and NPCC cited claims that ‘‘smart’’ features can provide up to 1,600 kWh in energy savings per year. (NEEA and NPCC, No. 7, p. 2) 
DOE expects that the impacts of any 
learning-based controls would vary based on specific field installation and usage scenarios. DOE is not aware of, and interested parties have not provided, any data that could be used to 
determine the impacts of learning-based controls on energy use (for example, by increasing the amount of time spent in either accessory low power mode or refrigeration low power mode, rather than vending mode). DOE also tentatively maintains its prior determination that it would be difficult to develop a repeatable and reproducible test procedure to evaluate the energy savings of such controls during a 24-hour test in a laboratory. For these reasons, DOE is not proposing to account for ‘‘learning-based’’ controls in the test procedure at this time. DOE has tentatively determined to continue accounting for operation in accessory low power mode and refrigeration low power mode, as described in the following sections. 
DOE requests comment on its 
tentative determination to not account for learning-based controls. DOE continues to seek data and information on the implementation and operation of such controls for BVMs. 
a. Accessory Low Power Mode 
Section 1.2 of appendix B defines 
accessory low power mode as a state in 
which a BVM’s lighting and/or other energy-using systems are in low power mode, but that is not a refrigeration low power mode. Functions that may constitute an accessory low power mode may include, for example, dimming or turning off lights, but does not include adjustment of the refrigeration system to elevate the temperature of the refrigerated compartment(s). Section 2.2.4 of appendix B states that accessory low power mode may be engaged for the final 6 hours of the 24-hour test period and requires that the BVM be operated in the lowest energy-consuming lighting and control settings for testing this mode. Section 2.2.4 also requires that any automatic activation of refrigeration 
low power modes be prevented during the accessory low power mode test period. 
The 24-hour test procedure starts after 
a BVM achieves stabilization as determined in vending mode. See section 2.1.1.1 of appendix B. Because the test period ends with 6 hours of operation in accessory low power mode, when the mode is engaged for testing, the BVM would end the test in a different operating state than at the start of the test. Although the refrigeration system and cabinet temperatures would likely not change with operation in an accessory low power mode (because accessory low power mode does not include adjustment of the refrigeration system to elevate the temperature of the refrigerated compartment), some 
VerDate Sep<11>2014 19:31 Mar 30, 2022 Jkt 256001 PO 00000 Frm 00011 Fmt 4701 Sfmt 4702 E:\FR\FM\31MRP2.SGM 31MRP2jspears on DSK121TN23PROD with PROPOSALS218946 Federal Register / Vol. 87, No. 62 / Thursday, March 31, 2022 / Proposed Rules 
transient recovery period may be 
required for a BVM to return to stable operation in vending mode after operating in accessory low power mode for 6 hours. If such a recovery period exists, testing the accessory low power mode during the middle of the 24-hour test period may be more representative by capturing any transition periods between operating modes. 
In the May 2021 RFI, DOE requested 
comment on whether BVMs require any recovery period following operation in accessory low power mode to return to stable operation in vending mode. 86 FR 27054, 27060. Additionally, DOE requested information on any drawbacks or potential test burdens that would result from testing the accessory low power mode during a period other than at the end of the 24-hour test period. Id. 
DOE did not receive comments on 
this topic. Through testing, DOE has observed that measured temperatures remain unchanged during operation in vending mode and accessory low power mode. The existing test approach also limits test burden by requiring only one operating mode transition during the 24- hour test period. Moving the accessory low power mode operating period to a period other than at the end of the 24- hour test period may require technicians to provide additional input to the unit during the test (i.e., once to enter 
accessory low power mode and again to re-enter vending mode), depending on the BVM’s controls. For these reasons, DOE is not proposing any changes to the current test procedure approach of requiring accessory low power mode to be tested at the end of the 24-hour test 
period. 
In the July 2015 Final Rule, DOE 
stated that BVMs may employ a variety of control strategies and control a variety of different components in accessory low power mode. 80 FR 45758, 45785. DOE established testing under the settings representing the maximum energy savings to avoid potential repeatability issues associated with identifying test control settings for BVMs with various types of accessory low power modes. Id. 
In the May 2021 RFI, DOE also 
requested comment on the typical average duration a BVM operates in accessory low power mode per day, what control settings users apply for accessory low power mode in the field, and whether multiple accessory low power mode test settings may be appropriate for BVMs with various control settings. 86 FR 27054, 27060. 
The CA IOUs commented that the 
current DOE test method (18 hours of normal operation and 6 hours of accessory low power mode) may not be 
fully representative of the most common locations and that DOE should conduct further research to verify this schedule. (CA IOUs, No. 6, p. 3) 
DOE acknowledges that BVMs may be 
used in a variety of locations and that the actual duration of accessory low power mode use will vary based on installation location. In the NOPR preceding the July 2015 Final Rule, DOE stated that the 6-hour duration was selected as a representative length of time for the low power mode test period based on the fact that it is intended to represent off hours between periods of vending when the facility may be closed or have low occupancy. 79 FR 46908, 46926. While DOE recognized that there are a range of types of low power mode controls and time periods for which these controls are enabled, DOE determined that a timeframe of 6 hours was a reasonable representation of average field use. Id. 
DOE is not aware of data indicating 
that durations other than the currently defined 6 hours would be more representative of typical BVM operation in accessory low power mode. The intent of the accessory low power mode test period remains unchanged from the July 2015 Final Rule approach (i.e., representing off hours between periods of vending when the facility may be closed or have low occupancy). Given the lack of any data supporting a change to this approach, DOE is not proposing any changes to the 6-hour duration for 
accessory low power mode testing. 
b. Refrigeration Low Power Mode 
Section 1.2 of appendix B defines 
refrigeration low power mode as a state 
in which a BVM’s refrigeration system is in low power mode because of elevation of the temperature of the refrigerated compartment(s). Section 2.3.2.1 of appendix B includes provisions for confirming the presence of a refrigeration low power mode, either through an increase in average next-to-vend beverage temperature or lack of compressor operation. Unlike accessory low power mode, appendix B does not include a direct test of refrigeration low power mode. Instead, BVMs with refrigeration low power mode receive a 3-percent reduction in DEC as measured. Section 2.3.2 of appendix B. 
In the July 2015 Final Rule, DOE 
determined that a 3-percent energy reduction was more appropriate than a physical test of refrigeration low power mode because refrigeration low power modes are extremely variable in their control strategies and operation and may require instructions from the manufacturer to accommodate specific 
provisions of a physical test. 80 FR 45758, 45785. DOE stated that a physical test would reduce consistency and repeatability and would make the method impractical to implement. Id. 
DOE established the 3-percent credit 
for refrigeration low power mode by testing several BVMs with this mode. DOE noted in the July 2015 Final Rule that this value is an average that is representative of the common types of refrigeration low power modes available in the marketplace. 80 FR 45758, 45786. 
In the May 2021 RFI, DOE requested 
comment on whether any amendments are needed to the definition of refrigeration low power mode or the corresponding refrigeration low power mode validation test method. 86 FR 27054, 27060. Additionally, DOE requested comment on whether any other BVM operating modes should be considered a refrigeration low power mode but cannot meet the current definition or validation test method (e.g., operating modes with little or no 
increase in refrigerated compartment temperature with some amount of compressor operation). Id. 
DOE did not receive any comment on 
these topics and is not proposing any changes to the current refrigeration low power mode and validation test method. 
In the May 2021 RFI, DOE also 
requested comment on the current approach of applying a 3-percent energy reduction for any BVMs with a refrigeration low power mode. 86 FR 27054, 27060. Specifically, DOE asked for comment regarding whether a physical test to account for energy reduction associated with the low power mode is feasible, whether any test method currently exists, and the 
burden associated with running such a test. Id. 
ASAP and NRDC, and the CA IOUs 
encouraged DOE to include a direct physical test instead of a fixed credit for refrigeration low power mode testing and to incorporate the resulting energy consumption into the daily energy consumption calculation. (ASAP and NRDC, No. 4, p. 1; CA IOUs, No. 6, p. 2) ASAP and NRDC also stated that the 3-percent credit may be inhibiting further improvements by failing to differentiate between refrigeration low power mode control strategies. (ASAP and NRDC, No. 4, p. 1) ASAP and NRDC stated that the accessory low power mode test could potentially be expanded to capture refrigeration low power modes, including a recovery period. (Id.) The CA IOUs suggested that the refrigeration low power mode test procedure should include an evaluation of the time and energy to return the

machine/, which both refer to restocking once per 
week. standard product to an IAT of 36 °F ± 
1°F, since the test may cause 
temperatures to drift. The CA IOUs 
estimated that this would be a primarily passive test and would likely only add 30 minutes of active work to the test method. (CA IOUs, No. 6, p. 2) 
Based on a review of operating 
instructions for BVMs currently available with refrigeration low power mode, DOE has tentatively determined that the challenges of implementing a refrigeration low power mode test would remain the same as those considered in the July 2015 Final Rule. Specifically, DOE observed that the implementation of refrigeration low power mode would depend on the specific control parameters entered by the user or installer regarding duration, operating temperatures, and operation of the refrigeration system. Additionally, establishing a consistent, repeatable test (i.e., measuring 
refrigeration low power mode operation over a defined duration from initiation of the low power mode until temperature recovery to the specified test temperature) may require specific instructions from the manufacturer to modify the controls in such a way to accommodate the specific requirements of a physical test. Testing on a consistent basis would also likely require an iterative process to identify the appropriate test settings. Due to the difficulty of accounting for the wide variety of refrigeration low power modes in a consistent, fair, and reasonable manner, as well as the potential burden of any such test approach, DOE is not proposing any changes to the current calculation approach to account for operation in refrigeration low power mode. 
DOE is also not proposing any 
changes to the 3-percent credit as the energy reduction associated with refrigeration low power mode. DOE acknowledges that the actual energy impact of refrigeration low power mode would vary depending on the user- specified control parameters for that mode, including duration and temperature settings or refrigeration system control. The investigative testing used to determine the 3-percent credit assumed 6 hours of operation in refrigeration low power mode, including 
the time needed for temperature recovery. 79 FR 46908, 46925–46926. DOE is not proposing any changes to the 6-hour test period for accessory low power mode, and therefore is maintaining the estimate of refrigeration low power mode impact based on that same duration. 
DOE requests comment on its initial 
determination to maintain the existing calculation approach to account for 
operation in refrigeration low power mode. DOE continues to seek information and data on whether the assumed operating period (6 hours) and corresponding energy consumption impact (3 percent) are appropriate for BVMs operating in refrigeration low power mode. 
7. Reloading and Recovery Period 
The existing DOE test procedure 
considers BVM performance only 
during stable operation (including any operation in accessory low power mode). During typical use, BVMs are regularly opened and restocked with warmer beverages. Accounting for BVM energy use during restocking periods and the subsequent product temperature recovery periods may better represent the actual energy use of BVMs during normal operation. 
As stated in section III.B, ANSI/ 
ASHRAE Standard 32.1–2017 provides an additional recovery test to determine the temperature recovery time of the BVM when loaded with product at a certain temperature, whereas appendix B contains no such test. This recovery test does not include a measurement of the corresponding energy consumption. Table 2 in ANSI/ASHRAE Standard 32.1–2017 specifies the reloaded sealed- beverage temperature, 90 °F, and the 
final instantaneous average next-to-vend beverage temperature, 40 °F, for the 
recovery test. Additionally, Table 4 in ANSI/ASHRAE Standard 32.1–2017 lists the door open durations, between 10 and 20 minutes, required during the recovery test while reloading the BVM. 
In the May 2021 RFI, DOE requested 
comment and supporting data on whether BVM restocking represents a significant energy consumption for BVMs. 86 FR 27054, 27061. DOE also requested comment and supporting data regarding the applicability of the recovery test described in ANSI/ ASHRAE Standard 32.1–2017. Id. DOE 
additionally requested comments and supporting data on the frequency and duration of door openings for reloading BVMs. Id. 
DOE did not receive any comments on 
these topics in response to the May 2021 RFI. Based on typical operating 
descriptions provided in vending industry websites,
13DOE expects that 
BVM restocking events are relatively infrequent, on the order of once per week, while the remainder of BVM operating time is spent in stable operation. DOE has tentatively 
determined that the current test procedure based on stable operation measures energy consumption during a representative average use cycle or period of use and is therefore not proposing any additional testing to account for reloading events. 
8. Alternate Refrigerants 
In an April 10, 2015 final rule, the 
Environmental Protection Agency listed 
propane (R–290), isobutane (R–600a), and the hydrocarbon blend R–441A as acceptable refrigerants for use in BVMs, subject to a 150-gram charge limit per refrigeration circuit and other safety measures to address flammability. 80 FR 19454, 19491. Due to the flammability of these refrigerants, BVMs using hydrocarbon refrigerants may need to implement additional controls and components to mitigate the risk of ignition from any potential refrigerant leaks. The need for such controls also may vary depending on the intended installation location for BVMs. 
In the May 2021 RFI, DOE requested 
comment on what additional components and controls manufacturers may need to add to their equipment when designing BVMs with alternative refrigerants. 86 FR 27054, 27061. DOE also requested comment on the typical settings used for such components and controls, if multiple settings are available. Id. DOE additionally 
requested comment on whether any test procedure modifications are necessary to account for the energy consumption associated with these components and 
controls and any corresponding impact on testing burden. Id. 
NAMA commented that the industry 
is currently partnered with Oak Ridge National Laboratory (‘‘ORNL’’) under a cooperative research and development agreement (‘‘CRADA’’) to collect information to inform how low global warming potential (‘‘low-GWP’’) refrigerants can be used to increase energy efficiency and comply with safety standards. NAMA stated that manufacturers and engineers at ORNL are currently focused on designing to protect against inadvertent leaks of flammable refrigerants and this technology may use a small amount of energy. Because of this, NAMA commented that any test procedure should not include the energy use of such safety measures. NAMA urged DOE to postpone amendments to test procedures until this research is concluded. (NAMA, No. 5, p. 2) 
The current BVM test procedure 
requires that, unless specified otherwise, all standard components that would be used during normal operation 
VerDate Sep<11>2014 19:31 Mar 30, 2022 Jkt 256001 PO 00000 Frm 00013 Fmt 4701 Sfmt 4702 E:\FR\FM\31MRP2.SGM 31MRP2jspears on DSK121TN23PROD with PROPOSALS218948 Federal Register / Vol. 87, No. 62 / Thursday, March 31, 2022 / Proposed Rules 
of the basic model in the field and are 
necessary to provide sufficient functionality for cooling and vending products in field installations (i.e., product inventory, temperature management, product merchandising (including, e.g., lighting or signage), 
product selection, and product transport and delivery) shall be in place during testing and shall be set to the maximum energy-consuming setting if manually adjustable. Section 2.2.5 of appendix B. Appendix B further requires that components not necessary for the inventory, temperature management, product merchandising (e.g., lighting or 
signage), product selection, or product transport and delivery shall be de- energized, or if they cannot be de- energized without preventing the operation of the machine, then they shall be placed in the lowest energy consuming state. Id. Any components 
with controls that are permanently operational and cannot be adjusted by the machine operator shall be operated in their normal setting. Id. 
Leak mitigation controls are a 
component that may be offered on BVMs. To the extent that leak mitigation controls are a user controllable accessory (i.e., if they can be turned off), 
BVMs are able to provide product inventory, temperature management, product merchandising, product selection, and product transport and delivery without the leak mitigation controls functioning. If the leak mitigation controls are permanently operational and cannot be adjusted by the user, the controls would always be operating in their normal setting. Section 2.2.5 of appendix B specifies test settings for accessories, including those not required for normal BVM operation and those with permanently operational controls. Because section 2.2.5 of appendix B already provides accessory test instructions, DOE has tentatively determined that this section currently addresses the use of leak mitigation controls during testing, but recognizes that further specification may help ensure reproducible testing. DOE is therefore proposing to amend the test procedure to provide specific instructions regarding the use of leak mitigation controls consistent with the existing requirements in appendix B. Specifically, DOE is proposing to specify in newly added section 2.2.5.11 of appendix B that if the use of leak mitigation controls is a user-controlled function (e.g., if the use of the controls 
is optional and intended only for specific installations), the controls would be de-energized or in their lowest energy consuming state during testing. If leak mitigation controls are not user- 
controlled and are always operational, DOE is proposing that the controls would be operational for testing. 
DOE acknowledges that the 
investigative work regarding leak mitigation is ongoing. However, if leak mitigation controls always operate and cannot be de-energized by the user, accounting for the energy use of such controls would ensure that the DOE test procedure measures energy consumption during a representative average use cycle or period of use as required by EPCA. (42 U.S.C. 6293(b)(3)) 
As discussed, the proposed 
instructions regarding leak mitigation controls are consistent with the existing requirements in section 2.2.5 of appendix B. Therefore, DOE does not expect the proposed amendments to affect current BVM ratings or result in any additional testing costs. 
DOE requests comment on the 
proposed instructions regarding leak mitigation control settings for BVM testing. Specifically, DOE requests information regarding how such controls are currently or expected to be implemented in BVMs, including whether the controls can be controlled by the user. 
The CA IOUs commented to 
encourage the adoption of low-GWP alternative refrigerants in this and other relevant rulemakings, noting that the use of R–134a in new vending machines has been banned in California since January 1, 2019. The CA IOUs stated that as of June 10, 2021, several BVM manufacturers continue to provide R– 134a systems, but that alternate refrigeration-based BVMs are growing in market share. The CA IOUs urged DOE to consider refrigerant choice as an 
efficiency design option for this rulemaking. The CA IOUs also recommended that DOE monitor ANSI/ ASHRAE Standard 15–2019 ‘‘Safety Standard for Refrigeration Systems’’ (‘‘ANSI/ASHRAE 15–2019’’) and UL Standard 541 ‘‘Refrigerated Vending Machines’’ (‘‘UL 541’’) to ensure that that the new test procedure will reflect the dynamic regulatory market around refrigerants. (CA IOUs, No. 6, p. 3) 
DOE has tentatively determined that 
the use of alternative refrigerants in BVMs does not require any specific amendments or instructions in the test procedure, except as noted with respect to leak mitigation controls. Additionally, the test procedure proposed in this NOPR, as well as the test procedure currently required for use, measures any energy efficiency benefits of alternative refrigerants. The use of alternative refrigerants to improve the efficiency of BVMs may be considered as a technology option in the 
analysis for any rulemaking to consider amended energy conservation standards for BVMs. DOE is monitoring ANSI/ ASHRAE 15–2019 and UL 541 to determine the applicability of alternative refrigerants to the BVM market. 
9. Connected Functions 
The current DOE test procedure for 
BVMs does not include specific test 
requirements regarding connected or smart features, but section 2.2.5 of appendix B provides instructions regarding accessories. Section 2.2.5 of appendix B generally requires all components necessary to provide sufficient functionality for cooling and vending products in field installations (i.e., product inventory, temperature 
management, product merchandising (including, e.g., lighting or signage), 
product selection, and product transport and delivery) to be in place during testing and set to the maximum energy- consuming setting if manually adjustable. Other components not necessary for such functionality are de- energized or set to their lowest energy consuming state. 
In the May 2021 RFI, DOE requested 
comment on the prevalence of 
connected functions, the BVM functions associated with them, how often they are used, and their corresponding energy use impacts. 86 FR 27054, 27061. DOE also requested comment on whether the existing DOE test procedure instructions for accessories in section 2.2.5 of appendix B adequately address test settings for connected functions. Id. 
NEEA and NPCC recommended that 
DOE include all energy consuming accessories or features in the BVM test procedure because their research indicates a trend in ‘‘intelligent’’ vending machines. NEEA and NPCC noted that these vending machines offer several additional features including the following: Machine/inventory management, flexible payment options, remote communication, Wi-Fi, phone charging, printing, and UV light sanitation. (NEEA and NPCC, No. 7, p. 2,3) 
ASAP and NRDC commented that the 
existing DOE test provisions regarding de-energizing non-essential accessories may affect connected functions that impact the overall energy use of a BVM, and encouraged DOE to investigate and capture the energy consumption associated with the connected functions that would normally be de-energized during testing. (ASAP and NRDC, No. 4, p. 3) 
Based on a review of BVMs available 
on the market, the types of connected

14DOE estimates that the BVM per-test cost is 
approximately $4,150, which includes the testing 
costs associated with running the low-power mode tests (e.g., running the low power mode test with 
the optional refrigeration low power mode verification). For each certified basic model, DOE requires a sample size of two units ($4,150 × 2 = 
$8,300). functions identified in the NEEA and 
NPCC comment do not appear to be common. Additionally, DOE lacks information on how frequently such functions would be used on BVMs with such functions. Without this data, DOE has no information to suggest that the current testing approach would produce results that are unrepresentative of an average use cycle or period of use. DOE therefore is not proposing any changes to the current test procedure approach in section 2.2.5 of appendix B as applicable to connected functions. As described, this approach requires testing with connected functions energized if they are necessary to provide sufficient functionality for cooling and vending products in field installations. Connected functions that are not necessary to provide sufficient functionality for cooling and vending products in field installations are de- energized or placed in the lowest energy consuming state. 
DOE requests comment on its 
tentative determination to maintain the existing test procedure approach in section 2.2.5 of appendix B as applicable to connected functions. DOE continues to request information and data on the prevalence of connected functions, the BVM functions associated with them, how often they are used, and their corresponding energy use impacts. 
10. Condenser Conditions 
In response to the May 2021 RFI, 
CoilPod commented that condenser 
coils become clogged in service, significantly impacting energy 
efficiency, and that the test procedure does not account for such coil fouling. CoilPod questioned whether it would be possible for the test procedure to account for the lack of coil cleanings by BVM owners. CoilPod stated that energy savings of approximately 20 percent could result from coil cleaning units. (CoilPod, No. 3, p. 1) 
DOE acknowledges that the energy 
consumption of BVMs can change over the lifetime of the equipment due to lack of maintenance or other factors. However, the DOE test procedure considers the performance of new BVMs without considering any potential long- term performance of the unit. Regarding the specific topic of condenser coil fouling, the end user is responsible for properly maintaining the BVM, including any condenser cleaning. Accordingly, DOE is not proposing to amend its test procedure to account for operation with clogged condensers. 
While DOE does not account for 
lifetime energy consumption in its test procedures, it does consider energy consumption over the lifetime of the equipment in the analysis conducted in support of developing potential amended energy conservation standards. In such an analysis, DOE may apply adjustment factors to consider performance degradation over time. 
DOE requests any additional 
information and data on how BVM energy consumption may change over the lifetime of the equipment. DOE also requests comment on whether any performance degradation occurs consistently for all BVMs, or whether the impacts vary depending on equipment type or specific equipment designs. 
11. Removal of Obsolete Provisions 
As discussed in section I.B, appendix 
B is required for testing BVMs 
manufactured on or after January 8, 2019. As such, appendix A is now obsolete for new units being manufactured. Therefore, DOE is proposing to remove appendix A. DOE is not proposing to redesignate appendix B as appendix A in order to avoid confusion regarding the appropriate version of the test procedure required for use. 
Additionally, the introductory note to 
appendix B currently explains when manufacturers are required to use either appendix A or appendix B for compliance with energy conservation standards and representations of energy use. DOE is proposing to amend the introductory note to remove the obsolete instructions and to instead provide clarifying language regarding application of the payment mechanism provisions, as discussed in section III.C.5 of this document. 
D. Test Procedure Costs and 
Harmonization 
1. Test Procedure Costs and Impact 
In this NOPR, DOE proposes to amend 
the existing test procedure for BVMs by 
referencing the most recent industry test standard, providing setup instructions for non-beverage shelves, updating the LAPT definition and instructions, requiring testing of coin and bill payment mechanisms if shipped with the BVM (but not until the compliance date of any amended energy conservation standards), specifying setup instructions for leak mitigation controls, and removing the obsolete appendix A. DOE has tentatively determined that these proposed amendments would not impact testing costs. 
Other than the proposed amendment 
to measure coin and bill payment mechanisms, the proposals in this NOPR are generally consistent with the requirements under the existing DOE 
test procedure. The proposed amendments harmonize with the industry standard or provide additional 
test instructions, but do not substantively change testing as currently required in appendix B. Accordingly, DOE has tentatively determined that manufacturers would be able to rely on data generated under the current test procedure should any of these additional proposed amendments be finalized, and would not incur additional costs as a result of the amended test procedure. 
Regarding the proposal to test with 
coin and bill payment mechanisms energized, DOE does not expect this proposal to impact testing costs until the compliance date of any amended energy conservation standards for BVMs, should such standards be adopted. At that time, the proposal would only require re-testing for any BVMs shipped with coin or bill payment mechanisms in place. For all other BVMs, the existing test procedure approach would remain unchanged. For any BVMs requiring re-testing upon the compliance date of any amended energy conservation standards for BVMs, DOE estimates re-testing costs of approximately $8,300 per basic model.
14 
DOE requests comment on the 
tentative determination that manufacturers would not incur any additional costs as a result of the proposed amended test procedure. DOE also requests comment on its estimate of per-test costs, should manufacturers re- test their BVM basic models to comply with any future amended BVM energy conservation standards. 
In response to the May 2021 RFI, 
NAMA commented to express concern over ongoing business interruptions and economic hardships caused by the COVID–19 pandemic. NAMA stated that amending test procedures at this time would place an undue burden on the industry and urged DOE to postpone amending test procedures. (NAMA, No. 5, p. 1, 2) 
As discussed, the proposed 
amendments would improve the clarity of the DOE test procedure while not substantively changing the existing test approach and the proposal to test with any coin and bill payment mechanisms energized would not be required for use

until the compliance date of any 
amended energy conservation standards for BVMs, should such standards be adopted. As a result, DOE has tentatively determined that the proposed amendments would not result in any additional costs for manufacturers and manufacturers would be able to rely on data generated under the current test procedure for BVMs already available on the market, until the compliance date of any amended energy conservation standards at which time any BVMs shipped with coin and bill payment mechanisms in place would be required to re-test. 
2. Harmonization With Industry 
Standards 
DOE’s established practice is to adopt 
relevant industry standards as DOE test procedures unless such methodology would be unduly burdensome to conduct or would not produce test results that reflect the energy efficiency, energy use, water use (as specified in EPCA) or estimated operating costs of that product during a representative average use cycle or period of use. 10 CFR 431.4; Section 8(c) of appendix A of 10 CFR part 430 subpart C. In cases where the industry standard does not meet EPCA statutory criteria for test procedures DOE will make modifications through the rulemaking process to these standards as the DOE test procedure. 
As discussed, the test procedure at 
appendix B incorporates by reference ANSI/ASHRAE Standard 32.1–2010. This standard provides definitions, test conditions, and test methods for measuring refrigerated volume and energy consumption of BVMs. The industry standards that DOE proposes to incorporate by reference via amendments described in this notice are discussed in further detail in section IV.M of this document. DOE requests 
comments on the benefits and burdens of the proposed updates and additions to industry standards referenced in the test procedure for BVMs. 
DOE notes that the BVM test 
procedure at appendix B includes a number of deviations to ANSI/ASHRAE Standard 32.1–2010. Specifically, appendix B only refers to certain sections of ANSI/ASHRAE Standard 32.1–2010, includes additional definitions, provides detailed setup and settings instructions, accounts for operation in low power modes and payment mechanism energy consumption, and provides rounding instructions. These deviations were established to limit test burden (i.e., by 
not requiring additional testing as specified in ANSI/ASHRAE Standard 32.1–2010), improve representativeness, 
and improve repeatability and reproducibility of the DOE test procedure as compared to the procedure in ANSI/ASHRAE Standard 32.1–2010. As discussed in sections III.B and III.C of this NOPR, DOE is proposing to incorporate by reference the most recent version of the industry standard, ANSI/ 
ASHRAE Standard 32.1–2017. This version of the standard addresses certain deviations between appendix B and ANSI/ASHRAE Standard 32.1– 2010. For other deviations not addressed in ANSI/ASHRAE Standard 32.1–2017, DOE has tentatively determined that the existing deviations in appendix B are necessary and appropriate. 
IV. Procedural Issues and Regulatory 
Review 
A. Review Under Executive Order 12866 
and 13563 
Executive Order (‘‘E.O.’’) 12866, 
‘‘Regulatory Planning and Review,’’ as supplemented and reaffirmed by E.O. 13563, ‘‘Improving Regulation and Regulatory Review, 76 FR 3821 (Jan. 21, 2011), requires agencies, to the extent permitted by law, to (1) propose or adopt a regulation only upon a reasoned determination that its benefits justify its costs (recognizing that some benefits and costs are difficult to quantify); (2) tailor regulations to impose the least burden on society, consistent with obtaining regulatory objectives, taking into account, among other things, and to the extent practicable, the costs of cumulative regulations; (3) select, in choosing among alternative regulatory approaches, those approaches that maximize net benefits (including potential economic, environmental, public health and safety, and other advantages; distributive impacts; and equity); (4) to the extent feasible, specify performance objectives, rather than specifying the behavior or manner of compliance that regulated entities must adopt; and (5) identify and assess available alternatives to direct regulation, including providing economic incentives to encourage the desired behavior, such as user fees or marketable permits, or providing information upon which choices can be made by the public. DOE emphasizes as well that E.O. 13563 requires agencies to use the best available techniques to quantify anticipated present and future benefits and costs as accurately as possible. In its guidance, OIRA has emphasized that such techniques may include identifying changing future compliance costs that might result from technological innovation or anticipated behavioral changes. For the reasons 
stated in the preamble, this proposed regulatory action is consistent with these principles. 
Section 6(a) of E.O. 12866 also 
requires agencies to submit ‘‘significant regulatory actions’’ to the Office of Information and Regulatory Affairs (‘‘OIRA’’) for review. OIRA has determined that this proposed regulatory action does not constitute a ‘‘significant regulatory action’’ under section 3(f) of E.O. 12866. Accordingly, this action was not submitted to OIRA for review under E.O. 12866. 
B. Review Under the Regulatory 
Flexibility Act 
The Regulatory Flexibility Act (5 
U.S.C. 601 et seq.) requires preparation 
of an initial regulatory flexibility analysis (‘‘IRFA’’) for any rule that by law must be proposed for public comment, unless the agency certifies that the rule, if promulgated, will not have a significant economic impact on a substantial number of small entities. As required by Executive Order 13272, ‘‘Proper Consideration of Small Entities in Agency Rulemaking,’’ 67 FR 53461 (August 16, 2002), DOE published procedures and policies on February 19, 2003, to ensure that the potential 
impacts of its rules on small entities are properly considered during the DOE rulemaking process. 68 FR 7990. DOE has made its procedures and policies available on the Office of the General Counsel’s website: energy.gov/gc/office- general-counsel. 
DOE reviewed this proposed rule 
under the provisions of the Regulatory Flexibility Act and the procedures and policies published on February 19, 2003. DOE certifies that the proposed rule, if adopted, would not have significant economic impact on a substantial number of small entities. The factual basis of this certification is set forth in the following paragraphs. 
Under 42 U.S.C. 6293, EPCA sets forth 
the criteria and procedures DOE must follow when prescribing or amending test procedures for covered products. EPCA requires that any test procedures prescribed or amended under this section be reasonably designed to produce test results which measure energy efficiency, energy use or estimated annual operating cost of a covered product during a representative average use cycle or period of use and not be unduly burdensome to conduct. (42 U.S.C. 6293(b)(3)) 
In addition, EPCA requires that DOE 
amend its test procedures for all covered products to integrate measures of standby mode and off mode energy consumption. (42 U.S.C. 6295(gg)(2)(A))

‘‘small business’’ OEMs identified as the small 
entities that would be subject to this proposal, consistent with DOE’s policies and procedures. See 68 FR 7990. Standby mode and off mode energy 
consumption must be incorporated into the overall energy efficiency, energy consumption, or other energy descriptor for each covered product unless the current test procedures already account for and incorporate standby and off mode energy consumption or such integration is technically infeasible. If an integrated test procedure is technically infeasible, DOE must prescribe a separate standby mode and off mode energy use test procedure for the covered product, if technically feasible. (42 U.S.C. 6295(gg)(2)(A)(ii)) Any such amendment must consider the most current versions of the International Electrotechnical Commission (‘‘IEC’’) Standard 62301
15 
and IEC Standard 6208716as applicable. 
(42 U.S.C. 6295(gg)(2)(A)) 
With respect to Refrigerated Bottled or 
Canned Beverage Vending Machines (‘‘BVMs’’), EPCA requires the test procedure to be based on the 2004 version of ANSI/ASHRAE Standard 32.1, ‘‘Methods of Testing for Rating Vending Machines for Bottled, Canned or Other Sealed Beverages.’’ (42 U.S.C. 6293(b)(15)) 
EPCA also requires that, at least once 
every 7 years, DOE evaluate test procedures for each type of covered product, including BVMs, to determine whether amended test procedures would more accurately or fully comply 
with the requirements for the test procedures to not be unduly burdensome to conduct and be reasonably designed to produce test results that reflect energy efficiency, energy use, and estimated operating costs during a representative average use cycle. (42 U.S.C. 6293(b)(1)(A)) 
DOE is publishing this proposed 
rulemaking in satisfaction of the 7-year review requirement specified in EPCA. (42 U.S.C. 6293(b)(1)(A)) 
In this NOPR, DOE proposes to 
update 10 CFR 431.294, ‘‘Uniform test method for the measurement of energy consumption of refrigerated bottled or canned beverage vending machines,’’ as follows: 
(1) Incorporate by reference the current 
industry standard ANSI/ASHRAE Standard 
32.1–2017. 
(2) Incorporate by reference the industry 
standard ANSI/AHAM HRF–1–2008 referenced in ANSI/ASHRAE Standard 32.1– 2017. 
(3) Maintain the existing DOE test 
procedure requirements that are not included in ANSI/ASHRAE Standard 32.1–2017. (4) Provide setup instructions for non- 
beverage shelves in refrigerated 
compartments. 
(5) Amend the definition of LAPT to allow 
for testing BVMs only capable of operating at temperatures below the specified test temperature. 
(6) Require testing of coin and bill payment 
mechanisms if shipped with the BVM (but not until the compliance date of any amended energy conservation standards). 
(7) Specify setup instructions for leak 
mitigation controls consistent with the existing test procedure instructions. 
(8) Remove the obsolete test procedure in 
appendix A. 
For manufacturers of BVMs, the Small 
Business Administration (‘‘SBA’’) has 
set a size threshold, which defines those entities classified as ‘‘small businesses’’ for the purposes of the statute. DOE used the SBA’s small business size standards to determine whether any small entities would be subject to the requirements of the rule. See 13 CFR 
part 121. The equipment covered by this rule is classified under North American Industry Classification System (‘‘NAICS’’) code 333318,
17‘‘Other 
Commercial and Service Industry Machinery Manufacturing.’’ The SBA sets a threshold of 1,000 employees or less for an entity to be considered as a small business for this category. 
DOE reviewed its Compliance 
Certification Database (‘‘CCD’’)
18and 
California Energy Commission’s Modernized Appliance Efficiency Database System (‘‘MAEDbS’’)
19to 
create a list of companies that import, private label, produce or manufacture the products covered by this rulemaking. DOE relied on public data and subscription-based market research tools (e.g., reports from Dun & 
Bradstreet
20) to determine company 
location, headcount, and annual revenue. DOE screened out companies that do not offer BVMs covered by this proposed rulemaking, do not meet the SBA’s definition of a ‘‘small business,’’ or are foreign-owned and operated. 
DOE identified six original equipment 
manufacturers (‘‘OEMs’’) of BVMs sold in the United States. Of the six OEMs identified, three OEMs meet the SBA definition of a ‘‘small business’’ and are 
not foreign-owned or operated. 
In this NOPR, DOE proposes to amend 
the existing test procedure for BVMs by referencing the most recent industry test standard, providing setup instructions for non-beverage shelves, updating the LAPT definition and instructions, requiring testing of coin and bill payment mechanisms if shipped with the BVM (but not until the compliance date of any amended energy conservation standards), specifying setup instructions for leak mitigation controls, and removing the obsolete appendix A. DOE has tentatively determined that these proposed amendments would not impact testing costs. 
Other than the proposed amendment 
to measure coin and bill payment mechanisms, the proposals in this NOPR are generally consistent with the requirements under the existing DOE test procedure. The proposed amendments harmonize with the industry standard or provide additional test instructions, but do not substantively change testing as currently required in appendix B. Accordingly, DOE has tentatively determined that manufacturers would be able to rely on data generated under the current test procedure should any of these additional proposed amendments be finalized, and would not incur additional costs as a result of the amended test procedure. 
Regarding the proposal to test with 
coin and bill payment mechanisms energized, DOE does not expect this proposal to impact testing costs until the compliance date of amended energy conservation standards for BVMs, should such standards be adopted. At that time, the proposal would require re- testing for BVMs shipped with coin or bill payment mechanisms in place. DOE estimates that the cost for third-party lab testing is approximately $8,300 per basic model. For all other BVMs, the existing test procedure approach would remain unchanged. 
Although the re-testing of BVMs 
shipped with coin or bill payment mechanisms is not required at this time, DOE developed cost estimates for the three small BVM manufacturers,
21 
should amended energy conservation standards be adopted in the future. For its analysis, DOE assumed that all the unique basic models identified in CCD and MAEDbS have coin or bill payment mechanisms and would need to be re-

figures from Dun and Bradstreet to determine the 
annual revenue of the three small BVM manufacturers. (The D&B login is accessible at: app.dnbhoovers.com/) 
23Testing costs of $8,300 per basic model for 19 
BVM models ($8,300 x 19 = $157,700). tested. Additionally, DOE’s cost 
estimate of $8,300 per basic model includes the testing costs associated with running all the optional tests (e.g., running the low power mode test with the optional refrigeration low power mode verification). DOE used these conservative assumptions in its analysis to avoid underestimating the potential test burden on small BVM manufacturers. 
The three small BVM manufacturers, 
on average, offer 10 unique basic models and have an average annual revenue of approximately $39.3 million.
22DOE 
estimates that the average cost for a small BVM manufacturer to re-test all of their BVM basic models would be less than one percent of their annual revenue. The small BVM manufacturer with the highest expected test burden offers 19 BVM models and has an annual revenue of $19.0 million. DOE 
estimates their re-testing costs could reach $157,700,
23which represents 
approximately 0.8 percent of their annual revenue. 
DOE has tentatively determined that 
the proposed amendments in this NOPR would result in minimal cost impacts for small BVM manufacturers. Furthermore, these minimal re-testing costs would not be incurred unless and until amended energy conservation standards for BVMs are adopted and would only apply to BVM basic models shipped with coin or bill payment mechanisms in place. Therefore, DOE initially concludes that the impacts of the proposed test procedure amendments proposed in this NOPR would not have a ‘‘significant economic impact on a substantial number of small entities,’’ and that the preparation of an IRFA is not warranted. DOE will transmit the certification and supporting statement of factual basis to the Chief Counsel for Advocacy of the Small Business Administration for review under 5 U.S.C. 605(b). 
DOE requests comment on the 
number of small BVM manufacturers and the cost impacts of this proposed rule on those small manufacturers. 
C. Review Under the Paperwork 
Reduction Act of 1995 
Manufacturers of BVMs must certify 
to DOE that their products comply with any applicable energy conservation standards. To certify compliance, manufacturers must first obtain test data for their products according to the DOE 
test procedures, including any amendments adopted for those test procedures. DOE has established regulations for the certification and recordkeeping requirements for all covered consumer products and commercial equipment, including BVMs. (See generally 10 CFR part 429.) The collection-of-information requirement for the certification and recordkeeping is subject to review and approval by OMB under the Paperwork Reduction Act (‘‘PRA’’). This requirement has been approved by OMB under OMB control number 1910–1400. Public reporting burden for the certification is estimated to average 35 hours per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. DOE is not proposing to amend the certification and recordkeeping requirements for BVMs. 
Notwithstanding any other provision 
of the law, no person is required to respond to, nor shall any person be subject to a penalty for failure to comply with, a collection of information subject to the requirements of the PRA, unless that collection of information displays a currently valid OMB Control Number. 
D. Review Under the National 
Environmental Policy Act of 1969 
In this NOPR, DOE proposes test 
procedure amendments that it expects will be used to develop and implement future energy conservation standards for the BVM test procedure, ‘‘Uniform Test Method for the Measurement of Energy Consumption of Refrigerated Bottled or Canned Vending Machines’’. 10 CFR 431.294. DOE has determined that this proposed rule falls into a class of actions that are categorically excluded from review under the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.) and DOE’s implementing regulations at 10 CFR part 1021. Specifically, DOE has determined that adopting test procedures for measuring energy efficiency of consumer products and industrial equipment is consistent with activities identified in 10 CFR part 1021, appendix A to subpart D, A5 and A6. Accordingly, neither an environmental assessment nor an environmental impact statement is required. 
E. Review Under Executive Order 13132 
Executive Order 13132, ‘‘Federalism,’’ 
64 FR 43255 (Aug. 4, 1999) imposes 
certain requirements on agencies formulating and implementing policies or regulations that preempt State law or that have federalism implications. The 
Executive order requires agencies to examine the constitutional and statutory authority supporting any action that would limit the policymaking discretion of the States and to carefully assess the necessity for such actions. The Executive order also requires agencies to have an accountable process to ensure meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications. On March 14, 2000, DOE published a statement of policy describing the intergovernmental consultation process it will follow in the development of such regulations. 65 FR 13735. DOE has examined this proposed rule and has determined that it would not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. EPCA governs and prescribes Federal preemption of State regulations as to energy conservation for the products that are the subject of this proposed rule. States can petition DOE for exemption from such preemption to the extent, and based on criteria, set forth in EPCA. (42 U.S.C. 6297(d)) No further action is required by Executive Order 13132. 
F. Review Under Executive Order 12988 
Regarding the review of existing 
regulations and the promulgation of 
new regulations, section 3(a) of Executive Order 12988, ‘‘Civil Justice Reform,’’ 61 FR 4729 (Feb. 7, 1996), imposes on Federal agencies the general duty to adhere to the following requirements: (1) Eliminate drafting errors and ambiguity, (2) write regulations to minimize litigation, (3) provide a clear legal standard for affected conduct rather than a general standard, and (4) promote simplification and burden reduction. Section 3(b) of Executive Order 12988 specifically requires that Executive agencies make every reasonable effort to ensure that the regulation (1) clearly specifies the preemptive effect, if any, (2) clearly specifies any effect on existing Federal law or regulation, (3) provides a clear legal standard for affected conduct while promoting simplification and burden reduction, (4) specifies the retroactive effect, if any, (5) adequately defines key terms, and (6) addresses other important issues affecting clarity and general draftsmanship under any 
guidelines issued by the Attorney General. Section 3(c) of Executive Order 12988 requires Executive agencies to review regulations in light of applicable standards in sections 3(a) and 3(b) to

determine whether they are met or it is 
unreasonable to meet one or more of them. DOE has completed the required review and determined that, to the extent permitted by law, the proposed rule meets the relevant standards of Executive Order 12988. 
G. Review Under the Unfunded 
Mandates Reform Act of 1995 
Title II of the Unfunded Mandates 
Reform Act of 1995 (‘‘UMRA’’) requires each Federal agency to assess the effects of Federal regulatory actions on State, local, and Tribal governments and the private sector. Public Law 104–4, sec. 201 (codified at 2 U.S.C. 1531). For a proposed regulatory action likely to result in a rule that may cause the expenditure by State, local, and Tribal governments, in the aggregate, or by the private sector of $100 million or more in any one year (adjusted annually for inflation), section 202 of UMRA requires a Federal agency to publish a written statement that estimates the resulting costs, benefits, and other effects on the national economy. (2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to develop an effective process to permit timely input by elected officers of State, local, and Tribal governments on a proposed ‘‘significant intergovernmental mandate,’’ and requires an agency plan for giving notice and opportunity for timely input to potentially affected small governments before establishing any requirements that might significantly or uniquely affect small governments. On March 18, 1997, DOE published a statement of policy on its process for intergovernmental consultation under UMRA. 62 FR 12820; also available at 
energy.gov/gc/office-general-counsel. DOE examined this proposed rule according to UMRA and its statement of policy and determined that the rule contains neither an intergovernmental mandate, nor a mandate that may result in the expenditure of $100 million or more in any year, so these requirements do not apply. 
H. Review Under the Treasury and 
General Government Appropriations Act, 1999 
Section 654 of the Treasury and 
General Government Appropriations Act, 1999 (Pub. L. 105–277) requires Federal agencies to issue a Family Policymaking Assessment for any rule that may affect family well-being. This proposed rule would not have any impact on the autonomy or integrity of the family as an institution. Accordingly, DOE has concluded that it is not necessary to prepare a Family Policymaking Assessment. I. Review Under Executive Order 12630 
DOE has determined, under Executive 
Order 12630, ‘‘Governmental Actions and Interference with Constitutionally Protected Property Rights’’ 53 FR 8859 (March 18, 1988), that this proposed regulation would not result in any takings that might require compensation under the Fifth Amendment to the U.S. Constitution. 
J. Review Under Treasury and General 
Government Appropriations Act, 2001 
Section 515 of the Treasury and 
General Government Appropriations Act, 2001 (44 U.S.C. 3516 note) provides for agencies to review most disseminations of information to the public under guidelines established by each agency pursuant to general guidelines issued by OMB. OMB’s guidelines were published at 67 FR 8452 (Feb. 22, 2002), and DOE’s guidelines were published at 67 FR 62446 (Oct. 7, 2002). Pursuant to OMB Memorandum M–19–15, Improving Implementation of the Information Quality Act (April 24, 2019), DOE published updated guidelines which are available at www.energy.gov/sites/prod/ 
files/2019/12/f70/DOE%20Final
%20Updated%20IQA%20Guidelines%20Dec%202019.pdf. DOE has 
reviewed this proposed rule under the OMB and DOE guidelines and has concluded that it is consistent with applicable policies in those guidelines. 
K. Review Under Executive Order 13211 
Executive Order 13211, ‘‘Actions 
Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use,’’ 66 FR 28355 (May 22, 2001), requires Federal agencies to prepare and submit to OMB, a Statement of Energy Effects for any proposed significant energy action. A ‘‘significant energy action’’ is defined as any action by an agency that promulgated or is expected to lead to promulgation of a final rule, and that (1) is a significant regulatory action under Executive Order 12866, or any successor order; and (2) is likely to have a significant adverse effect on the supply, distribution, or use of energy; or (3) is designated by the Administrator of OIRA as a significant energy action. For any proposed significant energy action, the agency must give a detailed statement of any adverse effects on energy supply, distribution, or use should the proposal be implemented, and of reasonable alternatives to the action and their expected benefits on energy supply, distribution, and use. 
The proposed regulatory action to 
amend the test procedure for measuring the energy efficiency of BVMs is not a 
significant regulatory action under Executive Order 12866. Moreover, it would not have a significant adverse effect on the supply, distribution, or use of energy, nor has it been designated as a significant energy action by the Administrator of OIRA. Therefore, it is not a significant energy action, and, accordingly, DOE has not prepared a Statement of Energy Effects. 
L. Review Under Section 32 of the 
Federal Energy Administration Act of 1974 
Under section 301 of the Department 
of Energy Organization Act (Pub. L. 95– 91; 42 U.S.C. 7101), DOE must comply with section 32 of the Federal Energy Administration Act of 1974, as amended by the Federal Energy Administration Authorization Act of 1977. (15 U.S.C. 788; ‘‘FEAA’’) Section 32 essentially provides in relevant part that, where a proposed rule authorizes or requires use of commercial standards, the notice of proposed rulemaking must inform the public of the use and background of such standards. In addition, section 32(c) requires DOE to consult with the Attorney General and the Chairman of the Federal Trade Commission (‘‘FTC’’) concerning the impact of the commercial or industry standards on competition. 
The proposed modifications to the 
test procedure for BVMs would 
incorporate testing methods contained in certain sections of the following commercial standards: ANSI/ASHRAE Standard 32.1–2017. DOE has evaluated these standards and is unable to conclude whether they fully comply with the requirements of section 32(b) of the FEAA (i.e., whether it was 
developed in a manner that fully provides for public participation, comment, and review.) DOE will consult with both the Attorney General and the Chairman of the FTC concerning the impact of these test procedures on competition, prior to prescribing a final rule. 
M. Description of Materials 
Incorporated by Reference 
In this NOPR, DOE proposes to 
incorporate by reference the 2017 test standard published by ANSI/ASHRAE, titled ‘‘Methods of Testing for Rating Refrigerated Vending Machines for Sealed Beverages.’’ ANSI/ASHRAE Standard 32.1–2017 is an industry- accepted test procedure that measures capacity and efficiency of BVMs. The test procedure proposed in this NOPR references various sections of ANSI/ ASHRAE Standard 32.1–2017 that address definitions, test setup,

24DOE has historically provided a 75-day 
comment period for test procedure NOPRs pursuant 
to the North American Free Trade Agreement, U.S.- Canada-Mexico (‘‘NAFTA’’), Dec. 17, 1992, 32 I.L.M. 289 (1993); the North American Free Trade Agreement Implementation Act, Public Law 103– 182, 107 Stat. 2057 (1993) (codified as amended at 
10 U.S.C.A. 2576) (1993) (‘‘NAFTA Implementation Act’’); and Executive Order 12889, ‘‘Implementation of the North American Free Trade Agreement,’’ 58 FR 69681 (Dec. 30, 1993). However, on July 1, 2020, the Agreement between the United States of America, the United Mexican States, and the United Canadian States (‘‘USMCA’’), Nov. 30, 2018, 134 Stat. 11 (i.e., the successor to NAFTA), went into 
effect, and Congress’s action in replacing NAFTA through the USMCA Implementation Act, 19 U.S.C. 4501 et seq. (2020), implies the repeal of E.O. 12889 
and its 75-day comment period requirement for technical regulations. Thus, the controlling laws are EPCA and the USMCA Implementation Act. Consistent with EPCA’s public comment period requirements for consumer products, the USMCA 
only requires a minimum comment period of 60 days. Consequently, DOE now provides a 60-day public comment period for test procedure NOPRs. instrumentation, test conduct, and 
calculations. ANSI/ASHRAE Standard 32.1–2017 is readily available at ANSI’s website at webstore.ansi.org. 
DOE also proposes to incorporate by 
reference the 2008 test standard published by ANSI/AHAM, titled ‘‘Energy And Internal Volume Of Refrigerating Appliances.’’ ANSI/AHAM HRF–1–2008 is referenced by ANSI/ ASHRAE Standard 32.1–2017 as the industry-accepted method for determining refrigerated volume for BVMs. By reference to ANSI/ASHRAE Standard 32.1–2017, the test procedure proposed in this NOPR refers only to the refrigerated volume section of ANSI/ AHAM HRF–1–2008. ANSI/AHAM HRF–1–2008 can be purchased at webstore.ansi.org/standards/aham/ahamhrf2008.

E. Issues on Which DOE Seeks Comment 
Although DOE welcomes comments 
on any aspect of this proposal, DOE is 
particularly interested in receiving comments and views of interested parties concerning the following issues: 
(1) DOE requests comment on its 
proposal to incorporate by reference the most current industry test standard, ANSI/ASHRAE Standard 32.1–2017, including the updated reference to ANSI/AHAM HRF–1–2008 for measuring refrigerated volume. Specifically, DOE requests comment on whether the proposed amendments would affect BVM ratings as measured under the existing test procedure or whether they would impact test burden. 
(2) DOE continues to request 
information on typical loads for non- refrigerated compartments in combination BVMs and, if DOE were to 
require such loads for testing, the potential impacts on combination BVM energy consumption and test burden. 
(3) DOE requests comment on the 
proposal to specify that non-beverage merchandise shelves not be loaded for testing BVMs. DOE seeks information on how such models are currently tested and on whether this proposal would impact current BVM ratings or test burden. 
(4) DOE requests comment on its 
initial determination to maintain the existing LAPT approach for units that operate only at temperatures above the IAT of 36 °F ± 1°F. DOE requests 
comment on its proposal to require testing at the highest integrated average temperature a given basic model is capable of maintaining for units that are only capable of operating at temperatures below the specified IAT of 36°F ± 1°F. 
(5) DOE requests comment on its 
proposal to require testing with coin and bill payment mechanisms energized, if they are included in the BVM as shipped. DOE requests comment on whether this approach would result in any additional test burden. DOE additionally requests comment on its proposal to require that any credit card payment mechanisms be disconnected or de-energized, if possible, or in place but set to the lowest energy consuming state, if they cannot be de-energized, for testing. DOE further requests information on the continued use of the 0.20 kWh/day energy use adder for BVMs shipped with no coin or bill payment mechanisms in place. DOE also requests comment on the proposal to not require the use of these amendments until the 
compliance date of any future amended energy conservation standards for BVMs. 
(6) DOE requests comment on its 
tentative determination to not account 
for learning-based controls. DOE continues to seek data and information on the implementation and operation of such controls for BVMs. 
(7) DOE requests comment on its 
initial determination to maintain the existing calculation approach to account for operation in refrigeration low power mode. DOE continues to seek information and data on whether the assumed operating period (6 hours) and corresponding energy consumption impact (3 percent) are appropriate for BVMs operating in refrigeration low power mode. 
(8) DOE requests comment on the 
proposed instructions regarding leak mitigation control settings for BVM testing. Specifically, DOE requests information regarding how such controls are currently or expected to be implemented in BVMs, including whether the controls can be controlled by the user. 
(9) DOE requests comment on its 
tentative determination to maintain the existing test procedure approach in section 2.2.5 of appendix B as applicable to connected functions. DOE continues to request information and data on the prevalence of connected functions, the BVM functions associated with them, how often they are used, and their corresponding energy use impacts. 
(10) DOE requests any additional 
information and data on how BVM energy consumption may change over the lifetime of the equipment. DOE also requests comment on whether any performance degradation occurs consistently for all BVMs, or whether the impacts vary depending on equipment type or specific equipment designs. 
(11) DOE requests comment on the 
tentative determination that manufacturers would not incur any additional costs as a result of the proposed amended test procedure. DOE also requests comment on its estimate of per-test costs, should manufacturers re- test their BVM basic models to comply with any future amended BVM energy conservation standards. 
(12) DOE requests comment on the 
number of small BVM manufacturers and the cost impacts of this proposed rule on those small manufacturers.

‘‘Definitions,’’ of ANSI/ASHRAE 32.1 the following definitions are also applicable to this appendix. 
Accessory low power mode means a state 
in which a beverage vending machine’s lighting and/or other energy-using systems are in low power mode, but that is not a refrigeration low power mode. Functions that 
VerDate Sep<11>2014 19:31 Mar 30, 2022 Jkt 256001 PO 00000 Frm 00022 Fmt 4701 Sfmt 4702 E:\FR\FM\31MRP2.SGM 31MRP2jspears on DSK121TN23PROD with PROPOSALS218957 Federal Register / Vol. 87, No. 62 / Thursday, March 31, 2022 / Proposed Rules 
may constitute an accessory low power mode 
may include, for example, dimming or turning off lights, but does not include adjustment of the refrigeration system to elevate the temperature of the refrigerated compartment(s). 
External accessory standby mode means 
the mode of operation in which any external, integral customer display signs, lighting, or digital screens are connected to mains power; do not produce the intended illumination, display, or interaction functionality; and can be switched into another mode automatically with only a remote user-generated or an internal signal. 
Low power mode means a state in which 
a beverage vending machine’s lighting, refrigeration, and/or other energy-using systems are automatically adjusted (without user intervention) such that they consume less energy than they consume in an active 
vending environment. 
Lowest application product temperature 
means either: 
(a) For units that operate only at 
temperatures above the integrated average temperature specified in Table 1 of ANSI/ ASHRAE 32.1, the lowest integrated average temperature a given basic model is capable of maintaining so as to comply with the temperature stabilization requirements specified in Section 7.2.2.2 of ANSI/ASHRAE 32.1; or 
(b) For units that operate only at 
temperatures below the integrated average temperature specified in Table 1 of ANSI/ ASHRAE 32.1, the highest integrated average temperature a given basic model is capable of maintaining so as to comply with the temperature stabilization requirements specified in Section 7.2.2.2 of ANSI/ASHRAE Standard 32.1. 
Refrigeration low power mode means a 
state in which a beverage vending machine’s refrigeration system is in low power mode because of elevation of the temperature of the refrigerated compartment(s). To qualify as low power mode, the unit must satisfy the requirements described in section 2.3.2.1 of this appendix. 
2. Test Procedure. Conduct testing 
according to Section 4, ‘‘Instruments’’; Section 5, ‘‘Vendible Capacity’’; Section 6, ‘‘Test Conditions’’; Section 7.1, ‘‘Test Procedures—General Requirements’’ (except Section 7.1.2 ‘‘Functionality’’ and Section 7.1.5.1 ‘‘Beverage Temperature Test Packages’’); and Section 7.2, ‘‘Energy Consumption Test’’ (except Section 7.2.2.6) of ANSI/ASHRAE 32.1, except as described in the following sections. 
2.1. Lowest Application Product 
Temperature. If a refrigerated bottled or 
canned beverage vending machine is not capable of maintaining an integrated average temperature of 36 °F (±1 °F) during the 24 
hour test period, the unit must be tested at the lowest application product temperature, as defined in section 1.1 of this appendix. 
2.2. Equipment Installation and Test Set 
Up. Except as provided in this section 2.2 of 
this appendix, the test procedure for energy consumption of refrigerated bottled or canned beverage vending machines shall be conducted in accordance with the methods specified in Sections 7.1 through 7.2.2.7 under ‘‘Test Procedures’’ of ANSI/ASHRAE 
32.1. 
2.2.1. Equipment Loading. Configure 
refrigerated bottled or canned beverage vending machines to hold the maximum number of standard products. 
2.2.1.1. Non-Beverage Shelves. Any shelves 
within the refrigerated compartment(s) intended only for non-beverage merchandise shall not be loaded for testing. 
2.2.1.2. Standard Products. The standard 
product shall be standard 12-ounce aluminum beverage cans filled with a liquid with a density of 1.0 grams per milliliter (g/ mL) ±0.1 g/mL at 36 °F. For product storage 
racks that are not capable of vending 12- ounce cans, but are capable of vending 20- ounce bottles, the standard product shall be 20-ounce plastic bottles filled with a liquid with a density of 1.0 g/mL ±0.1 g/mL at 36 °F. 
For product storage racks that are not capable 
of vending 12-ounce cans or 20-ounce bottles, the standard product shall be the packaging and contents specified by the manufacturer in product literature as the standard product (i.e., the specific 
merchandise the refrigerated bottled or canned beverage vending machine is designed to vend). 
2.2.1.3. Standard Test Packages. A 
standard test package is a standard product, as specified in section 2.2.1.2 of this appendix, altered to include a temperature- measuring instrument at its center of mass. 
2.2.2. Sensor Placement. The integrated 
average temperature of next-to-vend beverages shall be measured in standard test packages in the next-to-vend product locations specified in Section 7.1.5.2 of ANSI/ASHRAE 32.1. Do not run the thermocouple wire and other measurement apparatus through the dispensing door; the thermocouple wire and other measurement apparatus must be configured and sealed so as to minimize air flow between the interior refrigerated volume and the ambient room air. If a manufacturer chooses to employ a method other than routing thermocouple and sensor wires through the door gasket and ensuring the gasket is compressed around the wire to ensure a good seal, then it must maintain a record of the method used in the data underlying that basic model’s certification pursuant to 10 CFR 429.71. 
2.2.3. Vending Mode Test Period. The 
vending mode test period begins after temperature stabilization has been achieved, as described in ANSI/ASHRAE 32.1 Section 7.2.2.2 and continues for 18 hours for equipment with an accessory low power mode or for 24 hours for equipment without an accessory low power mode. For the vending mode test period, equipment that has energy-saving features that cannot be disabled shall have those features set to the most energy-consuming settings, except for as specified in section 2.2.4 of this appendix. In addition, all energy management systems shall be disabled. Provide, if necessary, any physical stimuli or other input to the machine needed to prevent automatic activation of low power modes during the vending mode test period. 
2.2.4. Accessory Low Power Mode Test 
Period. For equipment with an accessory low 
power mode, the accessory low power mode may be engaged for 6 hours, beginning 18 
hours after the temperature stabilization requirements established in Section 7.2.2.2 of ANSI/ASHRAE 32.1 have been achieved, and continuing until the end of the 24-hour test period. During the accessory low power mode test, operate the refrigerated bottled or canned beverage vending machine with the lowest energy-consuming lighting and control settings that constitute an accessory low power mode. The specification and tolerances for integrated average temperature in Table 2 of ANSI/ASHRAE 32.1 still apply, and any refrigeration low power mode must not be engaged. Provide, if necessary, any physical stimuli or other input to the machine needed to prevent automatic activation of refrigeration low power modes during the accessory low power mode test period. 
2.2.5. Accessories. Unless specified 
otherwise in this appendix or ANSI/ASRAE 
32.1, all standard components that would be used during normal operation of the basic model in the field and are necessary to provide sufficient functionality for cooling and vending products in field installations (i.e., product inventory, temperature 
management, product merchandising (including, e.g., lighting or signage), product 
selection, and product transport and delivery) shall be in place during testing and shall be set to the maximum energy- consuming setting if manually adjustable. Components not necessary for the inventory, temperature management, product merchandising (e.g., lighting or signage), 
product selection, or product transport and delivery shall be de-energized. If systems not required for the primary functionality of the machine as stated in this section cannot be de-energized without preventing the operation of the machine, then they shall be placed in the lowest energy consuming state. Components with controls that are permanently operational and cannot be adjusted by the machine operator shall be operated in their normal setting and consistent with the requirements of sections 2.2.3 and 2.2.4 of this appendix. The specific components and accessories listed in the subsequent sections shall be operated as stated during the test, except when controlled as part of a low power mode during the low power mode test period. 
2.2.5.1. Payment Mechanisms. 
(a) For purposes of demonstrating 
compliance with the energy conservation standards specified in §
431.296(b) for which 
compliance was required as of January 8, 2019, refrigerated bottled or canned beverage vending machines must be tested with no payment mechanism in place, the payment mechanism in-place but de-energized, or the payment mechanism in place but set to the lowest energy consuming state, if it cannot be de-energized. A default payment mechanism energy consumption value of 0.20 kWh/day shall be added to the primary rated energy consumption per day, as noted in section 2.3 of this appendix. 
(b) Refrigerated bottled or canned beverage 
vending machines required to comply with any amended energy conservation standards must be tested with any coin and or bill payment mechanisms shipped with the

model in place and energized. Credit card 
reader payment mechanisms shall be tested with the payment mechanism in-place but de-energized, or the payment mechanism in place but set to the lowest energy consuming state, if it cannot be de-energized. For refrigerated bottled or canned beverage vending machines shipped with no payment mechanism in place, or only a credit card reader payment mechanism in place, a default payment mechanism energy consumption value of 0.20 kWh/day shall be added to the primary rated energy consumption per day, as noted in section 2.3 of this appendix. 
2.2.5.2. Internal Lighting. All lighting that 
is contained within or is part of the internal physical boundary of the refrigerated bottled or canned beverage vending machine, as established by the top, bottom, and side panels of the equipment, shall be placed in its maximum energy consuming state. 
2.2.5.3. External Customer Display Signs, 
Lights, and Digital Screens. All external customer display signs, lights, and digital screens that are independent from the refrigeration or vending performance of the refrigerated bottled or canned beverage vending machine must be disconnected, disabled, or otherwise de-energized for the duration of testing. Customer display signs, lighting, and digital screens that are integrated into the beverage vending machine cabinet or controls such that they cannot be de-energized without disabling the refrigeration or vending functions of the refrigerated bottled or canned beverage vending machine or modifying the circuitry must be placed in external accessory standby mode, if available, or their lowest energy- consuming state. Digital displays that also serve a vending or money processing function must be placed in the lowest energy- consuming state that still allows the money processing feature to function. 
2.2.5.4. Anti-sweat or Other Electric 
Resistance Heaters. Anti-sweat or other electric resistance heaters must be operational during the entirety of the test procedure. Units with a user-selectable setting must have the heaters energized and set to the most energy-consumptive position. Units featuring an automatic, non-user- adjustable controller that turns on or off based on environmental conditions must be operating in the automatic state. Units that are not shipped with a controller from the point of manufacture, but are intended to be used with a controller, must be equipped with an appropriate controller when tested. 
2.2.5.5. Condensate Pan Heaters and 
Pumps. All electric resistance condensate 
heaters and condensate pumps must be installed and operational during the test. Prior to the start of the test, including the 24 hour period used to determine temperature stabilization prior to the start of the test period, as described in ANSI/ASHRAE 32.1 Section 7.2.2.2, the condensate pan must be dry. For the duration of the test, including the 24 hour time period necessary for temperature stabilization, allow any condensate moisture generated to accumulate in the pan. Do not manually add or remove water from the condensate pan at any time 
during the test. Any automatic controls that initiate the operation of the condensate pan heater or pump based on water level or ambient conditions must be enabled and operated in the automatic setting. 
2.2.5.6. Illuminated Temperature Displays. 
All illuminated temperature displays must be energized and operated during the test the same way they would be energized and operated during normal field operation, as recommended in manufacturer product literature, including manuals. 
2.2.5.7. Condenser Filters. Remove any 
nonpermanent filters provided to prevent particulates from blocking a model’s condenser coil. 
2.2.5.8. Security Covers. Remove any 
devices used to secure the model from theft 
or tampering. 
2.2.5.9. General Purpose Outlets. During 
the test, do not connect any external load to any general purpose outlets available on a unit. 
2.2.5.10. Crankcase Heaters and Other 
Electric Resistance Heaters for Cold Weather. Crankcase heaters and other electric resistance heaters for cold weather must be operational during the test. If a control system, such as a thermostat or electronic controller, is used to modulate the operation of the heater, it must be activated during the test and operated in accordance with the manufacturer’s instructions. 
2.2.5.11. Refrigerant Leak Mitigation 
Controls. If the use of leak mitigation controls 
is a user-controlled function (e.g., if the use 
of the controls is optional and intended only for specific installations), the controls shall be de-energized or in their lowest energy consuming state during testing. If leak mitigation controls are not user-controlled and are always operational, the controls shall be energized and operational for testing. 
2.3. Determination of Daily Energy 
Consumption. The daily energy consumption 
shall be equal to the primary rated energy consumption per day (ED), in kWh, determined in accordance with the calculation procedure in Section 7.2.3.1, ‘‘Calculation of Daily Energy Consumption,’’ of ANSI/ASHRAE 32.1 plus the default payment mechanism energy consumption value from section 2.2.5.1 of this appendix, if applicable. In Section 7.2.3.1 of ANSI/ ASHRAE 32.1, the energy consumed during the test shall be the energy measured during the vending mode test period and accessory low power mode test period, as specified in sections 2.2.3 and 2.2.4 of this appendix, as applicable. 
2.3.1. Refrigeration Low Power Mode. For 
refrigerated bottled or canned beverage vending machines with a refrigeration low power mode, multiply the value determined in section 2.3 of this appendix by 0.97 to determine the daily energy consumption of the unit tested. For refrigerated bottled or canned beverage vending machines without a refrigeration low power mode, the value determined in section 2.3 of this appendix is the daily energy consumption of the unit tested. 
2.3.1.1. Refrigeration Low Power Mode 
Validation Test Method. This test method is not required for the certification of 
refrigerated bottled or canned beverage vending machines. To verify the existence of a refrigeration low power mode, initiate the refrigeration low power mode in accordance with manufacturer instructions contained in product literature and manuals, after completion of the 6-hour low power mode test period. Continue recording all the data specified in Section 7.2.2.3 of ANSI/ASHRAE 32.1 until existence of a refrigeration low power mode has been confirmed or denied. The refrigerated bottled or canned beverage vending machine shall be deemed to have a refrigeration low power mode if either: 
(a) The following three requirements have 
been satisfied: 
(1) The instantaneous average next-to-vend 
beverage temperature must reach at least 4 °F 
above the integrated average temperature or 
lowest application product temperature, as applicable, within 6 hours. 
(2) The instantaneous average next-to-vend 
beverage temperature must be maintained at least 4 °F above the integrated average 
temperature or lowest application product temperature, as applicable, for at least 1 hour. 
(3) After the instantaneous average next-to- 
vend beverage temperature is maintained at or above 4 °F above the integrated average 
temperature or lowest application product temperature, as applicable, for at least 1 hour, the refrigerated beverage vending machine must return to the specified integrated average temperature or lowest application product temperature, as applicable, automatically without direct physical intervention. 
(b) Or, the compressor does not cycle on 
for the entire 6 hour period, in which case the instantaneous average beverage temperature does not have to reach 4 °F 
above the integrated average temperature or lowest application product temperature, as applicable, but, the equipment must still automatically return to the integrated average temperature or lowest application product temperature, as applicable, after the 6 hour period without direct physical intervention. 
2.3.2. Calculations and Rounding. In all 
cases, the daily energy consumption must be calculated with raw measured values and the final result rounded to units of 0.01 kWh/ day. 
3. Determination of Refrigeration Volume 
and Surface Area. 
3.1. Refrigerated Volume. Determine the 
‘‘refrigerated volume’’ of refrigerated bottled or canned beverage vending machines in accordance with Section 5.3, ‘‘Refrigerated Volume,’’ and Appendix C, ‘‘Measurement of Volume,’’ of ANSI/ASHRAE 32.1 including the referenced methodology in Section 4, ‘‘Method for Computing Refrigerated Volume of Refrigerators and Wine Chillers,’’ of AHAM HRF–1–2008. For combination vending machines, the ‘‘refrigerated volume’’ does not include any non-refrigerated compartment(s). 
3.2. Determination of Surface Area. Note: 
This section is not required for the 
certification of refrigerated bottled or canned 
beverage vending machines. Determine the
