I. Introduction 
DOE established an early assessment 
review process to conduct a more focused analysis of a specific set of facts or circumstances to allow DOE to determine that, based on statutory criteria, an amended test procedure is not warranted. In the case of PTACs and PTHPs, the purpose of the early assessment analysis is to assist DOE in determining whether to adopt industry standard ASHRAE 90.1–2019, which is consistent with DOE’s current test procedures, or whether clear and convincing evidence exists that this standard would not meet the requirements in the Energy Policy and Conservation Act (‘‘EPCA’’).
1(42 U.S.C. 
6314(a)(4)(B) and (C))2The purpose of 
the review is to limit the resources, from both DOE and stakeholders, committed to rulemakings that will not satisfy the requirements of EPCA. See 85 FR 8626, 
8653–8654 (Feb. 14, 2020). 
As part of the early assessment, DOE 
publishes an RFI in the Federal 
Register , announcing that DOE is 
soliciting comments, data and information on the question above. Based on the information received in response to the RFI and DOE’s own analysis, DOE will determine whether to proceed with a rulemaking for an amended test procedure. 
If DOE makes an initial determination 
that clear and convincing evidence does not exist to justify procedures other than those consistent with the industry testing standards referenced in ASHRAE 90.1–2019, DOE would engage in a notice and comment rulemaking to adopt the ASHRAE 90.1–2019 testing standards, which are consistent with the current test procedures and which would satisfy the Department’s 7-year- lookback test procedure review requirement under the statute (as discussed in section I.A of this document). Conversely, if DOE makes an initial 
determination that clear and convincing evidence does exist to justify the consideration of test procedures other than those referenced in ASHRAE 90.1– 2019, DOE would undertake the preliminary stages of a rulemaking to issue amended test procedures. Beginning such a rulemaking, however, would not preclude DOE from later making a determination that any such amended test procedures would not 
satisfy the requirements in EPCA, based upon the full suite of DOE’s analyses. Id. at 85 FR 8654. 
A. Authority 
EPCA among other things authorizes 
DOE to regulate the energy efficiency of a number of consumer products and certain industrial equipment. (42 U.S.C. 6291–6317) Title III, Part C
3of EPCA 
established the Energy Conservation Program for Certain Industrial Equipment. This equipment includes PTACs and PTHPs, the subjects of this document. (42 U.S.C. 6311(1)(I)) 
Under EPCA, DOE’s energy 
conservation program consists essentially of four parts: (1) Testing, (2) labeling, (3) Federal energy conservation standards, and (4) certification and enforcement procedures. Relevant provisions of EPCA include definitions (42 U.S.C. 6311), test procedures (42 U.S.C. 6314), labeling provisions (42 U.S.C. 6315), energy conservation standards (42 U.S.C. 6313), and the authority to require information and reports from manufacturers. (42 U.S.C. 6316) 
Federal energy efficiency 
requirements for covered equipment established under EPCA generally supersede State laws and regulations concerning energy conservation testing, labeling, and standards. (42 U.S.C. 6316(a) and (b); 42 U.S.C. 6297) DOE may, however, grant waivers of Federal preemption in limited instances for particular State laws or regulations, in accordance with the procedures and other provisions of EPCA. (42 U.S.C. 6316(b)(2)(D)) 
EPCA requires that the test 
procedures for PTACs and PTHPs be those generally accepted industry testing standards or rating procedures developed or recognized by the Air- Conditioning, Heating, and Refrigeration Institute (‘‘AHRI’’) or by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (‘‘ASHRAE’’), as referenced in ASHRAE Standard 90.1, ‘‘Energy Standard for Buildings Except Low-Rise Residential 
VerDate Sep<11>2014 16:14 Dec 07, 2020 Jkt 253001 PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 E:\FR\FM\08DEP1.SGM 08DEP1jbell on DSKJLSW7X2PROD with PROPOSALS78969 Federal Register / Vol. 85, No. 236 / Tuesday, December 8, 2020 / Proposed Rules 
Buildings’’ (‘‘ASHRAE Standard 90.1’’). 
(42 U.S.C. 6314(a)(4)(A)) If such an industry testing standard is amended, DOE must update its test procedure to be consistent with the amended industry testing standard, unless DOE determines, by rule published in the Federal Register and supported by clear 
and convincing evidence, that the amended test procedure would not meet the requirements in 42 U.S.C. 6314(a)(2) and (3) that DOE’s test procedure: (1) Be reasonably designed to measure energy efficiency or energy use during a representative average use cycle or period of use; and (2) not be unduly burdensome to conduct. (42 U.S.C. 6314(a)(4)(B) and (C)) 
EPCA also requires that, at least once 
every 7 years, DOE evaluate test procedures for each type of covered equipment, including PTACs and PTHPs, to determine whether amended test procedures would more accurately or fully comply with the requirements for the test procedures to be reasonably designed to produce test results that reflect energy efficiency, energy use, and estimated operating costs during a representative average use cycle and to not be unduly burdensome to conduct. (42 U.S.C. 6314(a)(1)) DOE is publishing this RFI also to collect data and information to inform its decision to satisfy the 7-year-lookback review requirement. 
B. Rulemaking History 
DOE’s current test procedures for 
PTACs and PTHPs are codified at 10 CFR 431.96. The test procedures were most recently amended after AHRI published AHRI Standard 310/380– 2014, ‘‘Standard for Packaged Terminal Air-Conditioners and Heat Pumps’’ (‘‘AHRI 310/380–2014’’) in February 2014. The 2014 version of the standard updated and superseded AHRI Standard 310/380–2004. In a final rule published on June 30, 2015, DOE amended the test procedures for PTACs and PTHPs. 80 FR 37136, 37136–37149. (‘‘June 2015 Final Rule’’). In the June 2015 Final Rule, DOE incorporated by reference certain sections of AHRI 310/380–2014. Id. at 80 FR 37148. DOE also 
incorporated by reference (1) American 
National Standard Institute (‘‘ANSI’’)/ ASHRAE Standard 16–1983 (RA2009), ‘‘Method of Testing for Rating Room Air Conditioners and Packaged Terminal Air Conditioners’’ (‘‘ASHRAE Standard 16’’); (2) ANSI/ASHRAE Standard 58– 1986 (RA2009), ‘‘Method of Testing for Rating Room Air Conditioner and Packaged Terminal Air Conditioner Heating Capacity’’ (‘‘ASHRAE Standard 58’’); and (3) ANSI/ASHRAE Standard 37–2009, ‘‘Methods of Testing for Rating Electrically Driven Unitary Air- 
Conditioning and Heat Pump Equipment’’ (‘‘ASHRAE Standard 37’’). Id. Additionally, DOE amended the 
PTAC and PTHP test procedures to specify an optional break-in period; explicitly require that wall sleeves be sealed; allow for the pre-filling of the condensate drain pan; require that measurements of cooling capacity be conducted using electrical instruments accurate to ± 0.5 percent of reading; and 
require testing with 14-inch deep wall sleeves and the filter option most representative of a typical installation. Id. at 80 FR 37149. 
AHRI published AHRI Standard 310/ 
380–2017, ‘‘Packaged Terminal Air- Conditioners and Heat Pumps’’ (‘‘AHRI 310/380–2017’’) in July 2017. The 2017 version of the standard updated and superseded AHRI Standard 310/380– 2014. The 2017 version of the standard incorporated DOE’s additional PTAC and PTHP test procedure specifications listed above. The DOE test procedures for PTACs and PTHPs are consistent with AHRI 310/380–2017. 
ASHRAE most recently updated 
Standard 90.1 in 2019. In the 2019 update, ASHRAE updated the AHRI 310/380 reference to the 2017 edition. As discussed, the DOE test procedures for PTACs and PTHPs are consistent with AHRI 310/380–2017. Clear and convincing evidence is required for DOE to adopt other procedures. (42 U.S.C. 6314(a)(4)(A)) 
Current Market 
Over the past five years, several 
manufacturers have introduced PTAC and PTHP models that are designed to take outdoor air into the unit, dehumidify the outdoor air, and introduce the dehumidified outdoor air to the conditioned space. These models are commonly referred to as ‘‘make-up air PTACs’’ or ‘‘make-up air PTHPs.’’ The test procedures for PTACs and PTHPs referenced in ASHRAE Standard 90.1 do not specify how to measure the energy use associated with dehumidification of makeup air transferred through the test unit, nor do they account for the additional conditioning required for this makeup air. 
Additionally, over the past five years, 
several PTAC and PTHP models have been introduced to the market that incorporate variable-speed compressors and are capable of part-load operation. The test procedures for PTACs and PTHPs referenced in ASHRAE Standard 90.1 do not specify how to measure the energy use associated with part-load performance of the test unit. II. Request for Information 
DOE is publishing this RFI to collect 
data and information during the early assessment review to inform its determination of whether to adopt ASHRAE 90.1–2019 in the absence of clear and convincing evidence that would justify the adoption of procedures other than those referenced in ASHRAE 90.1–2019. See 42 U.S.C. 
6314(a)(4)) Accordingly, DOE has identified specific issues on which it seeks input to aid in its analysis. DOE also welcomes comments on other issues relevant to its early assessment that may not specifically be identified in this document. 
A. Energy Use Measurements 
DOE’s current test procedures for 
PTACs and PTHPs are codified at 10 CFR 431.96. The test procedures measure energy use by operating the equipment in cooling-only and heating- only modes at standard rating conditions per AHRI Standard 310/380– 2014 and measuring the power input to the equipment in watts. The test metric for the cooling efficiency is the Energy Efficiency Ratio (‘‘EER’’), which is the ratio of the produced cooling effect of the PTAC or PTHP to its power input, expressed in Btu/watt-hour, and measured at standard rating conditions. The test metric for the heating efficiency is the Coefficient of Performance (‘‘COP’’), which is the ratio of the produced heating effect of the PTHP to its power input, expressed in watts/ watts, and measured at standard rating conditions. 
Issue 1: DOE seeks comment on 
whether the test procedure requirements in ASHRAE 90.1–2019 ( e.g., 
instrumentation testing configurations/ specifications, calculation methodologies) accurately measure energy use without adding undue burden to the test procedure. 
Issue 2: DOE seeks information on the 
need for DOE’s test procedure for PTACs and PTHPs to specify how to measure the energy use associated with dehumidification of ‘‘makeup air’’ for PTAC and PTHP models designed to take outdoor air into the unit, dehumidify the outdoor air, and introduce the dehumidified outdoor air to the conditioned space. 
Issue 3: DOE seeks information on the 
need for DOE’s test procedure for PTACs and PTHPs to specify how to measure the energy use associated with part-load operation. 
Issue 4: DOE requests information on 
whether any existing industry test procedures may be used to measure the energy use associated with ‘‘makeup

air’’ or part-load operation of PTACs 
and PTHPs. 
B. Representative Average Use Cycle 
The current DOE test procedure for 
PTACs and PTHPs, adopted in 2015, was reasonably designed to measure energy use during a representative average use cycle. Specifically, the test procedure adopted in 2015 provides instructions to measure the energy use of the equipment in cooling and heating 
modes at standard rating conditions, as prescribed in AHRI Standard 310/380– 2014. 
Issue 5: DOE seeks comment on 
whether ASHRAE 90.1–2019 and the references therein is reasonably designed to measure energy use during a representative use cycle. 
Issue 6: DOE also seeks comment on 
‘‘make-up air’’ and part load operation as they relate to a representative average use cycle for PTACs and PTHPs. 
III. Submission of Comments 
DOE invites all interested parties to 
submit in writing by February 22, 2021, comments and information on matters addressed in this notice and on other matters relevant to DOE’s consideration of whether DOE should adopt the most recent version of ASHRAE 90.1, which makes no substantive changes to DOE’s test procedures, or whether there is clear and convincing evidence that ASHRAE 90.1–2019 is not reasonably designed to measure energy efficiency or energy use during a representative average use cycle or period of use; and is not unduly burdensome to conduct.

SUMMARY : The FAA proposes to 
supersede Airworthiness Directive (AD) 2019–03–10, which applies to all Airbus SAS Model A300 series airplanes; and Model A300 B4–600, B4–600R, and F4– 600R series airplanes, and Model A300 C4–605R Variant F airplanes (collectively called Model A300–600 series airplanes). AD 2019–03–10 requires repetitive detailed visual inspections of the main landing gear (MLG) leg components and replacement of the MLG leg if cracked components are found. Since the FAA issued AD 2019–03–10, it was determined that additional actions (including inspections, modifications, and checks) are needed to address the unsafe condition. This proposed AD would continue to require the actions required by AD 2019–03–10. For certain airplanes, this proposed AD would also require modification of the MLG hinge arm by installing improved MLG hinge arm/barrel pins; an out-of-roundness check of removed pins; repetitive inspections of any affected pins and the associated connecting rod bushes, and replacement of the MLG leg if cracked components are found; and installation of an improved spacer as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is 
proposing this AD to address the unsafe condition on these products.
