Energy Conservation Program: Energy Conservation Standards for 
Direct Heating Equipment

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

ACTION: Notification of proposed determination and request for comment.

-----------------------------------------------------------------------

SUMMARY: The Energy Policy and Conservation Act, as amended (EPCA), 
prescribes energy conservation standards for various consumer products, 
including direct heating equipment (DHE). EPCA also requires the U.S. 
Department of Energy (DOE) to periodically determine whether more-
stringent, amended standards would be technologically feasible and 
economically justified, and would result in significant energy savings. 
After carefully considering the available market and technical 
information for these products, DOE has tentatively concluded in this 
document that more-stringent standards for DHE would not save a 
significant amount of energy. Further, depending on the product class, 
more-stringent standards for DHE would not be technologically feasible 
or economically justified. As such, DOE has tentatively determined that 
amended energy conservation standards are not needed. DOE requests 
comment on this proposed determination, as well as the associated 
analyses and results.

I. Synopsis of the Proposed Determination

    Title III, Part B \1\ of the Energy Policy and Conservation Act, as 
amended (EPCA or the Act),\2\ established the Energy Conservation 
Program for Consumer Products Other Than Automobiles. (42 U.S.C. 6291-
6309) These products include direct heating equipment, the subject of 
this notification of proposed determination (NOPD). (42 U.S.C. 
6292(a)(9))
---------------------------------------------------------------------------

    \1\ For editorial reasons, upon codification in the U.S. Code, 
Part B was redesignated Part A.
    \2\ All references to EPCA in this document refer to the statute 
as amended through America's Water Infrastructure Act of 2018, 
Public Law 115-270 (Oct. 23, 2018).
---------------------------------------------------------------------------

    DOE is issuing this NOPD pursuant to the statutory requirement in 
EPCA that not later than three years after issuance of a final 
determination not to amend standards, DOE must publish either a 
notification of determination that standards for the product do not 
need to be amended, or a notice of proposed rulemaking (NOPR) including 
new proposed energy conservation standards (proceeding to a final rule, 
as appropriate). (42 U.S.C. 6295(m)(3)(B))
    ``Direct heating equipment'' is defined at 10 Code of Federal 
Regulations (CFR) 430.2 as vented home heating equipment and unvented 
home heating equipment (i.e., ``vented heaters'' and ``unvented 
heaters,'' respectively). These latter terms are also defined at 10 CFR 
430.2. Federal energy conservation standards at 10 CFR 430.32(i) 
currently exist for vented home heating equipment, but there are 
currently no standards for unvented home heating equipment.
    For this proposed determination, DOE evaluated whether energy 
conservation standards should be proposed for unvented heaters. In 
addition, DOE analyzed vented heaters subject to the standards 
specified in 10 CFR 430.32(i).
    For unvented home heating equipment, DOE has previously determined 
that unvented heaters have minimal potential for energy savings, as 
they are installed within a conditioned space and all waste heat will 
be transferred to the conditioned space. 75 FR 20112, 20130 (April 16, 
2010). Further, the test procedure only includes test methods for 
annual energy consumption for primary electric heaters and rated output 
for all unvented heaters and does not include a test method or metric 
for energy efficiency. See 10 CFR part 430 subpart B appendix G.
    For vented home heating equipment, DOE analyzed the current vented 
heater market and compared it to the market during the previous 
rulemakings. DOE found the market has shrunk since these previous 
rulemakings but that the available technology options and efficiency 
levels have not changed significantly. In those earlier rulemakings, 
DOE found that while some efficiency levels were technologically 
feasible, they were not economically justified. DOE also examined the 
energy use of the vented heaters considered in the previous 
rulemakings.
    Based on the results of these analyses, as summarized and explained 
in section III of this document, DOE has tentatively determined that 
energy conservation standards for unvented heaters are not warranted 
due to insignificant potential energy savings. Similarly, DOE has 
tentatively determined that amended energy conservation standards for 
vented heaters are not warranted due to insignificant energy savings, 
and furthermore, depending on the product class, more-stringent 
standards for vented heaters would not be technologically feasible or 
economically justified. Consequently, DOE proposes to take no further 
action vis-[agrave]-vis the energy conservation standards for DHE at 
this time.

II. Authority and Background

    The following section briefly discusses the statutory authority 
underlying this proposed determination, as well as some of the 
historical background relevant to the establishment of energy 
conservation standards for unvented home heating equipment and vented 
home heating equipment.

A. Authority

    EPCA, Public Law 94-163 (42 U.S.C. 6291-6317, as codified), among 
other things, authorizes DOE to regulate the energy efficiency of a 
number of consumer products and certain industrial equipment. Title 
III, part B of EPCA established the Energy Conservation Program for 
Consumer Products Other Than Automobiles, which sets forth a variety of 
provisions designed to improve energy efficiency. The National 
Appliance Energy Conservation Act of 1987 (NAECA), Public Law 100-12, 
amended EPCA to include DHE in the list of covered products and 
prescribed the initial energy conservation standards for DHE. (42 
U.S.C. 6292(a)(9); 42 U.S.C. 6295(e)(3)) NAECA amendments to EPCA also 
directed DOE to conduct two cycles of rulemakings to determine whether 
to amend these standards. (42 U.S.C. 6295(e)(4))
    Under EPCA, DOE's energy conservation program for covered products 
consists essentially of four parts: (1) Testing, (2) labeling, (3) 
Federal energy conservation standards, and (4) certification and 
enforcement procedures. Relevant provisions of the Act 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).
    Subject to certain criteria and conditions, DOE is required to 
develop test procedures to measure the energy efficiency, energy use, 
or estimated annual operating cost of each covered product. (42 U.S.C. 
6295(o)(3)(A) and 42 U.S.C. 6295(r)) Manufacturers of covered products 
must use the prescribed DOE test procedure as the basis for certifying 
to DOE that their products comply with the applicable energy 
conservation standards adopted under EPCA and when making 
representations to the public regarding the energy use or efficiency of 
those products. (42 U.S.C. 6293(c) and 42 U.S.C. 6295(s)) Similarly, 
DOE must use these test procedures to determine whether the products 
comply with standards adopted pursuant to EPCA. (42 U.S.C. 6295(s)) The 
currently applicable DOE test procedures for unvented home heating 
equipment and vented home heating equipment, subsets of DHE, appear at 
10 CFR part 430, subpart B, appendix G (Appendix G) and appendix O 
(Appendix O), respectively.
    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 in limited instances for particular State laws or 
regulations, in accordance with

[[Page 77019]]

the procedures set forth under 42 U.S.C. 6297(d).
    As noted previously, NAECA amended EPCA to include the initial 
energy conservation standards for DHE--limited to gas DHE only--which 
were based on annual fuel utilization efficiency (AFUE). NAECA 
established separate standards for ``wall fan type,'' ``wall gravity 
type,'' ``floor,'' and ``room'' DHE, further divided by input 
capacity.\3\ (42 U.S.C. 6295(e)(3)) The statutory energy conservation 
standards for gas DHE were incorporated into the CFR in a final rule 
published on February 7, 1989 (February 1989 final rule) and applied to 
all gas vented home heating equipment manufactured beginning January 1, 
1990. 54 FR 6062, 6077. The initial statutory energy conservation 
standards published in the February 1989 final rule are presented in 
Table II.1 of this document.
---------------------------------------------------------------------------

    \3\ DOE defines ``direct heating equipment'' as vented home 
heating equipment and unvented home heating equipment. 10 CFR 430.2. 
For the purpose of the energy conservation standards, DOE further 
delineates vented home heating equipment as ``gas wall fan type,'' 
``gas wall gravity type,'' ``gas floor,'' and ``gas room,'' and then 
further divides product classes by input capacity. 10 CFR 430.32(i).

----------------------------------------------------------------------------------------------------------------

    Pursuant to the amendments to EPCA contained in the Energy 
Independence and Security Act of 2007 (EISA 2007), Public Law 110-140, 
any final rule for new or amended energy conservation standards 
promulgated after July 1, 2010, is required to address standby mode and 
off mode energy use. (42 U.S.C. 6295(gg)(3)) Specifically, when DOE 
adopts a standard for a covered product after that date, it must, if 
justified by the criteria for adoption of standards under EPCA (42 
U.S.C. 6295(o)), incorporate standby mode and off mode energy use into 
a single standard, or, if that is not feasible, adopt a separate 
standard for such energy use for that product. (42 U.S.C. 
6295(gg)(3)(A)-(B)) In this analysis, DOE considers such energy use in 
its determination of whether energy conservation standards need to be 
adopted or amended.
    EPCA also requires under 42 U.S.C. 6295(m), that DOE must 
periodically review its already established energy conservation 
standards for a covered product no later than six years from the 
issuance of a final rule establishing or amending a standard for a 
covered product. This six-year-lookback provision requires that DOE 
publish either a determination that standards do not need to be amended 
or a NOPR, including new proposed standards (proceeding to a final 
rule, as appropriate). (42 U.S.C. 6295(m)(1)) EPCA further provides 
that, not later than three years after the issuance of a final 
determination not to amend standards, DOE must publish either a 
notification of determination that standards for the product do not 
need to be amended, or a NOPR including new proposed energy 
conservation standards (proceeding to a final rule, as appropriate). 
(42 U.S.C. 6295(m)(3)(B)) DOE must make the analysis on which the 
determination is based publicly available and provide an opportunity 
for written comment. (42 U.S.C. 6295(m)(2))
    A determination that amended standards are not needed must be based 
on consideration of whether amended standards will result in 
significant conservation of energy, are technologically feasible, and 
are cost-effective. (42 U.S.C. 6295(m)(1)(A) and 42 U.S.C. 6295(n)(2)) 
Additionally, any new or amended energy conservation standard 
prescribed by the Secretary for any type (or class) of covered product 
shall be designed to achieve the maximum improvement in energy 
efficiency which the Secretary determines is technologically feasible 
and economically justified. (42 U.S.C. 6295(o)(2)(A)) Among the factors 
DOE considers in evaluating whether a proposed standard level is 
economically justified includes whether the proposed standard at that 
level is cost-effective, as defined under 42 U.S.C. 
6295(o)(2)(B)(i)(II). Under 42 U.S.C. 6295(o)(2)(B)(i)(II), an 
evaluation of cost-effectiveness requires DOE to consider savings in 
operating costs throughout the estimated average life of the covered 
products in the type (or class) compared to any increase in the price, 
initial charges, or maintenance expenses for the covered products that 
are likely to result from the standard. (42 U.S.C. 6295(n)(2) and 42 
U.S.C. 6295(o)(2)(B)(i)(II))
    A NOPR including new proposed standards, must be based on the 
criteria established under 42 U.S.C. 6295(o). (42 U.S.C. 6295(m)(1)(B)) 
The criteria in 42 U.S.C. 6295(o) require that standards be designed to 
achieve the maximum improvement in energy efficiency, which the 
Secretary determines is technologically feasible and economically 
justified, and they must result in significant conservation of energy. 
(42 U.S.C. 6295(o)(2)(A) and 42 U.S.C. 6295(o)(3)(B)) In deciding 
whether a proposed standard is economically justified, DOE must 
determine, after receiving public comment, whether the benefits of the

[[Page 77020]]

standard exceed its burdens. (42 U.S.C. 6295(o)(2)(B)(i)) DOE must make 
this determination after receiving comments on the proposed standard, 
and by considering, to the greatest extent practicable, the following 
seven statutory factors:
    (1) The economic impact of the standard on manufacturers and 
consumers of the products subject to the standard;
    (2) The savings in operating costs throughout the estimated average 
life of the covered products in the type (or class) compared to any 
increase in the price, initial charges, or maintenance expenses for the 
covered products that are likely to result from the standard;
    (3) The total projected amount of energy (or as applicable, water) 
savings likely to result directly from the standard;
    (4) Any lessening of the utility or the performance of the covered 
products likely to result from the standard;
    (5) The impact of any lessening of competition, as determined in 
writing by the Attorney General, that is likely to result from the 
standard;
    (6) The need for national energy and water conservation; and

    DOE is publishing this NOPD in satisfaction of the three-year 
review requirement in EPCA.

B. Rulemaking History

    As noted, DOE codified the statutory standards for gas DHE into the 
CFR in the February 1989 final rule. 54 FR 6062 (Feb. 7, 1989). 
Pursuant to the requirements in EPCA (42 U.S.C. 6295(e)(4)), DOE 
conducted two cycles of rulemaking for DHE to determine whether to 
amend these standards. DOE published a final rule concluding the first 
round of rulemaking on April 16, 2010 (75 FR 20112 (April 2010 final 
rule)), and the Department published a final rule concluding the second 
round on October 17, 2016 (81 FR 71325 (October 2016 final 
determination)).
1. Current Standards
    In the April 2010 final rule, DOE prescribed the current energy 
conservation standards for gas vented home heating equipment 
manufactured on and after April 16, 2013. 75 FR 20112, 20234-20235 
(April 16, 2010). These standards consolidated the input rate ranges of 
all gas wall gravity type vented heaters at or below 27,000 Btu/h, 
consolidated the input rate ranges of all gas room vented heaters at or 
below 20,000 Btu/h, and are set forth in DOE's regulations at 10 CFR 
430.32(i)(2) and repeated in Table II.2 of this document. There are 
currently no standards for unvented home heating equipment.

----------------------------------------------------------------------------------------------------------------

2. April 2010 Final Rule
a. Unvented Heaters
    DOE did not adopt standards for unvented heaters in the April 2010 
final rule, having determined that a standard would produce little 
energy savings (largely due to the fact that any heat losses are 
dissipated directly into the conditioned space) and because of 
limitations in the applicable DOE test procedure. 75 FR 20112, 20130 
(April 16, 2010). The unvented heaters test procedure, Appendix G, 
includes neither a method for measuring energy efficiency nor a 
descriptor for representing the efficiency of unvented heaters. 
Instead, Appendix G provides a method to measure and calculate the 
rated output for all unvented heaters and annual energy consumption of 
primary electric unvented heaters.
b. Vented Heaters
    DOE established the current energy conservation standards for 
vented heaters in the April 2010 final rule, but the agency determined 
that standards more stringent than those adopted would not be 
economically justified. 75 FR 20112, 20217-20219 (April 16, 2010). At 
the next highest level of stringency, trial standard level (TSL) 3, DOE 
projected the fraction of consumers experiencing an increased life-
cycle cost would be 19 percent for gas wall fan type vented heaters, 33 
percent for gas wall gravity type vented heaters, 25 percent for gas 
floor vented heaters, and 20 percent for gas room vented heaters. Id. 
at 75 FR 20218. DOE also projected a decrease in the industry net 
present value (INPV) of 42.4 percent, with total conversion costs 
(costs for redesigning and retooling product lines not already meeting 
the amended standards) of roughly half of the industry value. Id. DOE 
also found that the industry had consolidated significantly over the 
prior decade due to a steady decline in shipments; the three 
competitors that account for nearly 100 percent of the market had 
survived up to that point by consolidating a variety of legacy brands 
and products and providing them in replacement situations; and thus, 
each of the three competitors, two of which are small business 
manufacturers, would face the prospect of significantly upgrading 
several low-volume product lines. Id. DOE found that for the most part, 
manufacturers did not have significant volume over which to spread the 
capital conversion costs required by TSL 3 and all higher TSLs, meaning 
that margins will likely be pressured unless consumers accept large 
increases in product price. Id. DOE projected even more harmful impacts 
for small business (e.g., the typical small business manufacturer in 
the industry would require investment equal to 426 percent of its 
annual earnings before interest and taxes). Id. Concern with the 
potential impacts on competition and small business were also raised by 
the U.S. Department of Justice, Antitrust Division based on its review 
of the evaluated TSLs. Id. at 75 FR 20235-20236.

[[Page 77021]]

    In the April 2010 final rule, DOE concluded that at the next higher 
level of stringency over that which was adopted, the benefits of energy 
savings, emission reductions, and consumer net present value (NPV) 
benefits would be outweighed by the economic burden on some consumers, 
the large capital conversion costs that could result in a large 
reduction in INPV for the manufacturers of vented heaters, and the 
potential for small business manufacturers of vented heaters to reduce 
their product offerings or to be forced to exit the market completely, 
thereby reducing competition in the vented heater market. Id. at 75 FR 
20218-20219.
    Compliance with the adopted standards (i.e., those currently at 10 
CFR 430.32(i)(2)) was required for all vented home heating equipment 
manufactured beginning April 16, 2013.
3. October 2016 Final Determination
a. Unvented Heaters
    In the October 2016 final determination, DOE concluded that energy 
conservation standards for unvented heaters would result in negligible 
energy savings. 81 FR 71325, 71327 (Oct. 17, 2016). DOE also explained 
that the test procedure for unvented heaters in Appendix G, includes a 
calculation of annual energy consumption based on a single assignment 
of active mode hours for unvented heaters that are used as the primary 
heating source for the home. Id. at 81 FR 71328. For unvented heaters 
that are not used as the primary heating source for the home, there are 
no provisions for calculating either the energy efficiency or annual 
energy consumption. Id. DOE further explained that pursuant to 42 
U.S.C. 6295(o)(3), DOE is prohibited from prescribing a new or amended 
standard for a covered consumer product if a test procedure has not 
been prescribed for that consumer product, and as such, DOE could not 
consider standards for these products at that time. Id.
b. Vented Heaters
    In the October 2016 final determination, DOE found that few changes 
to the industry and product offerings had occurred since the April 2010 
final rule, and, therefore, the conclusions presented in that final 
rule were still valid. 81 FR 71325, 71327-71328 (Oct. 17, 2016). For 
the October 2016 final determination, DOE reviewed the vented heater 
market, including product literature and product listings in the DOE 
Compliance Certification Management System (CCMS) database and the Air-
Conditioning, Heating, and Refrigeration Institute (AHRI) product 
directory.\4\ Id. at 81 FR 71327. DOE found that the number of models 
offered in each of the vented heater product classes had decreased 
overall since the April 2010 final rule, and the agency concluded that 
this finding supported the notion that the vented heater market was 
shrinking and that product lines were mainly maintained as replacements 
for existing vented heater units, and that new product lines generally 
were not being developed. Id.
---------------------------------------------------------------------------

accessed for the October 2016 final determination on July 16, 2015).

determination on July 16, 2015).
---------------------------------------------------------------------------

    For the October 2016 final determination DOE also examined 
available technologies used to improve the efficiency of vented 
heaters. DOE analyzed products on the market at the time through 
product teardowns and engaged in manufacturer interviews to obtain 
further information in support of its analysis. 81 FR 71325, 71327 
(Oct. 17, 2016). Most of the technology options on the market and 
evaluated for the October 2016 final determination (i.e., improved heat 
exchanger, induced draft, electronic ignition, and a two-speed blower 
for gas wall fan type vented heaters) were those considered as part of 
the vented heater rulemaking analysis for the April 2010 final rule. 
Id. DOE determined that the technology options available for vented 
heaters were likely to have limited potential for achieving energy 
savings.\5\ Id. Furthermore, DOE concluded that the costs of technology 
options would likely be similar or higher than in the previous 
rulemaking analysis due to reduced shipments and, therefore, reduced 
purchasing power of vented heater manufacturers. Id. DOE also evaluated 
condensing technology for gas wall fan type vented heaters, which had 
become available after the April 2010 final rule, and, therefore, was 
not evaluated as part of that rulemaking. Id. DOE concluded that this 
technology option would not be economically justified when analyzed for 
the Nation as a whole due to the significant increase in initial 
product cost for products using this technology and the potential for 
severe manufacturer impacts due to the necessary capital conversion 
costs if an energy conservation standard were adopted at this level. 
Id. at 81 FR 71327-71328.
---------------------------------------------------------------------------

    \5\ DOE noted that for gas room vented heaters with input 
capacity up to 20,000 Btu/h, the maximum AFUE available on the 
market increased from 59 percent in 2009 (only one unit at this 
input capacity was available on the market at that time) to 71 
percent in 2015. DOE found that this was due to heat exchanger 
improvements only because these units do not use electricity. Due to 
the small input capacity, DOE found that this increase in AFUE 
(based on heat exchanger improvements relative to input capacity) 
was not representative of or feasible for the other gas room vented 
heater product classes.
---------------------------------------------------------------------------

    DOE acknowledged that the vented heater industry had seen further 
consolidation since the April 2010 final rule, with the total number of 
manufacturers declining from six to four. Id. at 81 FR 71328. 
Furthermore, according to manufacturers,\6\ shipments further decreased 
since the April 2010 final rule, and, therefore, it would be more 
difficult for manufacturers to recover capital expenditures resulting 
from increased standards. Id. DOE acknowledged that vented heater units 
continue to be produced primarily as replacements and that the market 
is small, and expected that shipments would continue to decrease and 
amended standards would likely accelerate the trend of declining 
shipments. Id. Moreover, DOE anticipated that small business impacts 
resulting from amended standards could be significant, as two of the 
four remaining manufacturers subject to vented heater standards were 
small businesses. Id.
---------------------------------------------------------------------------

    \6\ Information obtained during confidential manufacturer 
interviews.
---------------------------------------------------------------------------

    DOE concluded in the October 2016 final determination that due to 
the lack of advancement in the vented heater industry since the April 
2010 final rule in terms of product offerings, available technology 
options and associated costs, and declining shipment volumes, amending 
the vented heater energy conservation standards would impose a 
substantial burden on manufacturers of vented heaters, particularly to 
small manufacturers. 81 FR 71325, 71328 (Oct. 17, 2016). DOE noted that 
it had rejected higher TSLs for vented heaters in the April 2010 final 
rule due to significant impacts on industry profitability, risks of 
accelerated industry consolidation, and the likelihood that small 
manufacturers would experience disproportionate impacts that could lead 
them to discontinue product lines or exit the market altogether, and 
the Department stated that the market and the manufacturers' 
circumstances at the time were similar to when DOE evaluated amended 
energy conservation standards for vented heaters for the April 2010 
final rule. Id. at 81 FR

[[Page 77022]]

71328-71329. Accordingly, DOE concluded that amended energy 
conservation standards for vented heaters were not economically 
justified at any level above the current standard levels because 
benefits of more-stringent standards would not outweigh the burdens, 
and the Department determined not to amend the vented heater energy 
conservation standards. Id. at 81 FR 71329.
    In the October 2016 final determination, DOE also considered 
whether to establish energy conservation standards for standby mode and 
off mode electrical energy use, noting that fossil fuel energy use in 
standby mode and off mode is already included in the AFUE metric and 
that electric standby mode and off mode energy use is small in 
comparison to fossil fuel energy use. Id. Because the standards for 
vented heaters were not amended, DOE concluded it was not required 
under EPCA to adopt amended standards that include standby mode and off 
mode energy use, and due to the relatively small potential for energy 
savings, DOE declined to do so. Id.
4. February 2019 Request for Information
    On February 26, 2019, DOE published a request for information (RFI) 
(February 2019 RFI) to solicit information from the public to help DOE 
determine whether amended standards for DHE would result in significant 
energy savings and whether such standards would be technologically 
feasible and economically justified. 84 FR 6095.
5. Process Rule
    On February 14, 2020, DOE published in the Federal Register a final 
rule which updated the procedures, interpretations, and policies that 
DOE will follow in the consideration and promulgation of new or revised 
appliance energy conservation standards and test procedures under EPCA. 
85 FR 8626; see also 10 CFR part 430, subpart C, appendix A (i.e., 
``Process Rule''). The Process Rule requires DOE to conduct an early 
assessment, which includes publishing a notice in the Federal Register 
announcing that DOE is considering a rulemaking proceeding and 
soliciting the submission of related comments, including data and 
information on whether DOE should proceed with the rulemaking, 
including whether any new or amended rule would be cost-effective, 
economically justified, technologically feasible, or would result in a 
significant savings of energy. Section 6(a)(1) of the Process Rule. 
Based on the responses received to the early assessment and DOE's own 
analysis, DOE will then determine whether to proceed with a rulemaking 
for a new or amended energy conservation standard or an amended test 
procedure. Id. If DOE determines that a new or amended standard would 
not satisfy all of the applicable statutory criteria, DOE would engage 
in a notice and comment rulemaking to issue a determination that a new 
or amended standard is not warranted. Id. If DOE receives sufficient 
information suggesting it could justify a new or amended standard or 
the information received is inconclusive with regard to the statutory 
criteria, DOE would undertake the preliminary stages of a rulemaking to 
issue or amend an energy conservation standard. Section 6(a)(2) of the 
Process Rule. In those instances where the early assessment either 
suggested that a new or amended energy conservation standard might be 
justified or in which the information was inconclusive on this, DOE 
will examine the potential costs and benefits and energy savings 
potential of a new or amended energy conservation standard. Section 
6(a)(3) of the Process Rule.
    DOE will first look to the projected energy savings that are likely 
to result in ``significant energy savings,'' as required under 42 
U.S.C. 6295(o)(3)(B) to ensure that DOE avoids setting a standard that 
``will not result in significant conservation of energy.'' \7\ Section 
6(b)(1) of the Process Rule. To determine whether energy savings could 
be significant, the projected energy savings from a potential maximum 
technologically feasible (max-tech) standard will be evaluated against 
a threshold of 0.3 quadrillion Btus (quads) of site energy saved over a 
30-year period. Section 6(b)(2) of the Process Rule. If the projected 
max-tech energy savings do not meet or exceed this threshold, those 
max-tech savings would then be compared to the total energy usage of 
the covered product to calculate a potential percentage reduction in 
energy usage. Section 6(b)(3) of the Process Rule. If this comparison 
does not yield a reduction in site energy use of at least 10 percent 
over a 30-year period, the analysis will end, and DOE will propose to 
determine that no significant energy savings would likely result from 
setting new or amended standards. Section 6(b)(4) of the Process Rule. 
If either one of the thresholds is reached, DOE will conduct analyses 
to ascertain whether a standard can be prescribed that produces the 
maximum improvement in energy efficiency that is both technologically 
feasible and economically justified and still constitutes significant 
energy savings at the level determined to be economically justified. 
Section 6(b)(5) of the Process Rule.
---------------------------------------------------------------------------

    \7\ EPCA defines ``energy efficiency'' as the ratio of the 
useful output of services from an article of industrial equipment to 
the energy use of such article, measured according to the Federal 
test procedures. (42 U.S.C. 6311(3)) EPCA defines ``energy use'' as 
the quantity of energy directly consumed by an article of industrial 
equipment at the point of use, as measured by the Federal test 
procedures. (42 U.S.C. 6311(4)) Given this context, DOE relies on 
site energy as the appropriate metric for evaluating the 
significance of energy savings.
---------------------------------------------------------------------------

    Because this rulemaking was already in progress at the time the 
revised Process Rule was published, DOE will apply those provisions 
moving forward (i.e., rather than reinitiating the entire rulemaking 
process).
6. Gas Industry Petition for Rulemaking
    EPCA specifies requirements when promulgating an energy 
conservation standard for a covered product that has two or more 
subcategories. DOE must specify a different standard level for a type 
or class of product that has the same function or intended use, if DOE 
determines that products within such group: (A) Consume a different 
kind of energy from that consumed by other covered products within such 
type (or class); or (B) have a capacity or other performance-related 
feature which other products within such type (or class) do not have 
and such feature justifies a higher or lower standard. (42 U.S.C. 
6295(q)(1)) In determining whether a performance-related feature 
justifies a different standard for a group of products, DOE must 
consider such factors as the utility to the consumer of the feature and 
other factors DOE deems appropriate. Id. Any rule prescribing such a 
standard must include an explanation of the basis on which such higher 
or lower level was established. (42 U.S.C. 6295(q)(2)) Related to the 
establishment of product classes, EPCA provides that the Secretary may 
not prescribe an amended or new standard for covered products if the 
Secretary finds (and publishes such finding) that interested persons 
have established by a preponderance of the evidence that the standard 
is likely to result in the unavailability in the United States in any 
covered product type (or class) of performance characteristics 
(including reliability), features, sizes, capacities, and volumes that 
are substantially the same as those generally available in the United 
States at the time of the Secretary's finding. (42 U.S.C. 6295(o)(4))
    On November 1, 2018, DOE published in the Federal Register a notice 
of petition for rulemaking and request for comment regarding a petition 
for

[[Page 77023]]

rulemaking submitted by Spire, Inc., the National Gas Supply 
Association, the National Propane Gas Association, the American Public 
Gas Association, and the American Gas Association (Gas Industry 
Petition). 83 FR 54883. The petition requested that DOE issue an 
interpretive rule stating that DOE's proposed energy conservation 
standards for residential furnaces and commercial water heaters would 
result in the unavailability of ``performance characteristics'' within 
the meaning of the EPCA (i.e., by setting standards which can only be 
met by condensing combustion technology products/equipment and thereby 
precluding the distribution in commerce of non-condensing combustion 
technology products/equipment) and withdraw the proposed energy 
conservation standards for residential furnaces and commercial water 
heaters based upon such findings. 83 FR 54883, 54885 (Nov. 1, 2018).
    On July 11, 2019, following consideration of the Gas Industry 
Petition, public comments, and other information received on the 
petition, DOE published in the Federal Register a notice granting in 
part and denying in part of the petition for rulemaking, a notice of 
proposed interpretative rule (NOPIR), and request for comment. 84 FR 
33011 (July 2019 NOPIR). The July 2019 NOPIR granted the request for an 
interpretive rule, but denied the petition to withdraw the proposed 
rules for residential furnaces and commercial water heaters. Id. at 84 
FR 33021. Specifically, the July 2019 NOPIR proposed to revise DOE's 
interpretation of EPCA's ``features'' provision in the context of 
condensing and non-condensing technology used in residential furnaces, 
commercial water heating equipment, and similarly situated appliances 
(where permitted by EPCA). Id. at 84 FR 33020. DOE stated that as 
compared to products that rely on non-condensing technology, products 
that use condensing technology may result in more complicated/costly 
installations, require physical changes to a home that impact 
aesthetics (e.g., by adding new venting into the living space or 
decreasing closet or other storage space), and may result in some 
enhanced level of fuel switching. Id. DOE also acknowledged that 
although energy efficiency improvements may pay for themselves over 
time, there is a significant increase in first-cost associated with 
residential furnaces and commercial water heaters using condensing 
technology, and for consumers with difficult installation situations 
(e.g., inner-city row houses) there would be the added cost of 
potentially extensive venting modifications. Id.
    DOE proposed in the July 2019 NOPIR to interpret the statute to 
provide that adoption of energy conservation standards that would limit 
the market to natural gas and/or propane furnaces, water heaters, or 
similarly situated products/equipment (where permitted by EPCA) that 
use condensing combustion technology would result in the unavailability 
of a performance-related feature within the meaning of 42 U.S.C. 
6295(o)(4) and 42 U.S.C. 6313(a)(6)(B)(iii)(II)(aa) and 42 U.S.C. 
6316(a). 84 FR 33011, 33021 (July 11, 2019).
    In the July 2019 NOPIR, DOE initially assumed that if it were to 
adopt an interpretation consistent with the Gas Industry Petition, it 
would suffice to set product/equipment classes largely based upon the 
key distinction of whether an appliance utilizes condensing or non-
condensing combustion technology. However, a number of commenters on 
the proposed interpretive rule suggested that such an approach may not 
adequately resolve the issue at hand, as presented in the petition. 
Instead, these commenters suggested that the agency should focus on 
preservation of Category I venting, or alternatively maintaining 
compatibility with all types of existing venting (i.e., Categories I, 
II, III, and IV). In light of these comments, DOE decided to issue a 
supplemental notice of proposed interpretive rule (where these comments 
are presented in further detail), which was published in the Federal 
Register on September 24, 2020 (the September 2020 SNOPIR). 85 FR 
60090. In that document, DOE tentatively determined to consider a more 
involved class structure which turns on the maintenance of 
compatibility with existing venting categories, and the Department 
stated that it seeks further information on the potential feasibility, 
burdens, and other implications of implementing such a venting-
compatibility approach. The comment period on the September 2020 SNOPIR 
was originally scheduled to end on October 26, 2020.
    However, on September 25, 2020, and October 6, 2020, DOE received 
requests from A.O. Smith and Lennox, respectively, seeking an extension 
of the comment period on the September 2020 SNOPIR. On September 29, 
2020, DOE received a request from the submitters of the Gas Industry 
Petition seeking prompt action on their petition. Balancing these 
competing requests, DOE published in the Federal Register on October 
22, 2020 a notice extending the public comment period for submitting 
comments and data on the SNOPIR to November 9, 2020. 85 FR 67312. DOE 
will analyze the information received in comments on the September 2020 
SNOPIR, and it will consider both potential venting-compatibility 
approaches, as well as its original proposed approach.
    DOE plans to consider the comments received on the July 2019 NOPIR 
and the September 2020 SNOPIR, after which the Department will 
determine whether and how to proceed with the interpretive rule in 
response to the Gas Industry Petition. As necessary, DOE would then 
consider any required changes to its energy conservation standards for 
DHE, including product class designations.

III. General Discussion

    DOE developed this proposed determination after a review of the DHE 
market, including product literature and product listings in the DOE 
CCMS database and the AHRI product directory. DOE also considered 
written comments, data, and information from interested parties that 
represent a variety of interests. In response to the February 2019 RFI, 
DOE received eight substantive comments from interested parties, which 
are listed in Table III.1.\8\ This notice addresses issues raised by 
these commenters.
---------------------------------------------------------------------------

    \8\ DOE also received a comment that was not responsive to the 
RFI.

A. Product Classes and Scope of Coverage

    When evaluating and establishing new or amended energy conservation 
standards, DOE divides covered products into product classes by the 
type of energy used or by capacity or other performance-related 
features that justify differing standards. (42 U.S.C. 6295(q)) In 
making a determination whether a performance-related feature justifies 
a different standard, DOE must consider such factors as the utility of 
the feature to the consumer and other factors DOE determines are 
appropriate. Id. The scope of coverage is discussed in further deal in 
section III.A.1 of this document. The product classes for this proposed 
determination are discussed in further detail in section III.A.2 of 
this document.
1. Scope of Coverage and Definitions
    This NOPD covers those products that meet the definitions of 
``direct heating equipment,'' which is defined as vented home heating 
equipment and unvented home heating equipment. 10 CFR 430.2. ``Home 
heating equipment, not including furnaces'' likewise means vented home 
heating equipment and unvented home heating equipment. Id. The existing 
energy conservation standards at 10 CFR 430.32(i)(2) apply only to 
product classes of vented home heating equipment. There are no existing 
energy conservation standards for unvented home heating equipment.
a. Unvented Heaters
    Unvented heaters are those products that meet the definitions for 
``unvented home heating equipment,'' as codified at 10 CFR 430.2. Under 
that provision, ``Unvented home heating equipment'' means a class of 
home heating equipment, not including furnaces, used for the purpose of 
furnishing heat to a space proximate to such heater directly from the 
heater and without duct connections and includes electric heaters and 
unvented gas and oil heaters. DOE further defines the various sub-types 
of unvented heaters at 10 CFR 430.2 as follows:
    (1) ``Baseboard electric heater'' means an electric heater which is 
intended to be recessed in or surface mounted on walls at floor level, 
which is characterized by long, low physical dimensions, and which 
transfers heat by natural convection and/or radiation.
    (2) ``Ceiling electric heater'' means an electric heater which is 
intended to be recessed in, surface mounted on, or hung from a ceiling, 
and which transfers heat by radiation and/or convection (either natural 
or forced).
    (3) ``Electric heater'' means an electric appliance in which heat 
is generated from electrical energy and dissipated by convection and 
radiation and includes baseboard electric heaters, ceiling electric 
heaters, floor electric heaters, portable electric heaters, and wall 
electric heaters.
    (4) ``Floor electric heater'' means an electric heater which is 
intended to be recessed in a floor, and which transfers by radiation 
and/or convection (either natural or forced).
    (5) ``Portable electric heater'' means an electric heater which is 
intended to stand unsupported, and can be moved from place to place 
within a structure. It is connected to electric supply by means of a 
cord and plug, and transfers heat by radiation and/or convention 
(either natural or forced).
    (6) ``Primary heater'' means a heating device that is the principal 
source of heat for a structure and includes baseboard electric heaters, 
ceiling electric heaters, and wall electric heaters.
    (7) ``Supplementary heater'' means a heating device that provides 
heat to a space in addition to that which is supplied by a primary 
heater. Supplementary heaters include portable electric heaters.
    (8) ``Unvented gas heater'' means an unvented, self-contained, 
free-standing, non-recessed gas-burning appliance which furnishes warm 
air by gravity or fan circulation.
    (9) ``Unvented oil heater'' means an unvented, self-contained, 
free-standing, non-recessed oil-burning appliance which furnishes warm 
air by gravity or fan circulation.
    (10) ``Wall electric heater'' means an electric heater (excluding 
baseboard electric heaters) which is intended to be recessed in or 
surface mounted on walls, which transfers heat by radiation and/or 
convection (either natural or forced) and which includes forced 
convectors, natural convectors, radiant heaters, high wall or valance 
heaters.
    DOE received no recommended changes to the unvented heater 
definitions in response to its request in the February 2019 RFI.
b. Vented Heaters
    Vented heaters are those products that meet the definitions for 
``vented home heating equipment,'' as codified at 10 CFR 430.2. Under 
that provision, ``vented home heating equipment'' or ``vented heater'' 
means a class of home heating equipment, not including furnaces, 
designed to furnish warmed air to the living space of a residence, 
directly from the device, without duct connections (except that boots 
not to exceed 10 inches beyond the casing may be permitted) and 
includes: Vented wall furnace, vented floor furnace, and vented room 
heater. DOE further defines the various sub-types of vented heaters at 
10 CFR 430.2 as follows:
    (1) ``Vented floor furnace'' means a self-contained vented heater 
suspended from the floor of the space being heated, taking air for 
combustion from outside this space. The vented floor furnace

[[Page 77025]]

supplies heated air circulated by gravity or by a fan directly into the 
space to be heated through openings in the casing.
    (2) ``Vented room heater'' means a self-contained, free standing, 
non-recessed, vented heater for furnishing warmed air to the space in 
which it is installed. The vented room heater supplies heated air 
circulated by gravity or by a fan directly into the space to be heated 
through openings in the casing.
    (3) ``Vented wall furnace'' means a self-contained vented heater 
complete with grilles or the equivalent, designed for incorporation in, 
or permanent attachment to, a wall of a residence and furnishing heated 
air circulated by gravity or by a fan directly into the space to be 
heated through openings in the casing.
    AHRI recommended against revisions or additions to the vented 
heater definitions, stating that the definitions are appropriate as 
written and capture the entirety of the market. (AHRI, No. 6 at p. 2) 
No other comments were received regarding the definitions relevant to 
vented heaters.
2. Product Classes
    In general, when evaluating and establishing energy conservation 
standards, DOE divides the covered product into classes by the type of 
energy used, the capacity, or other performance-related feature that 
justifies a different standard. (42 U.S.C. 6295(q)) In making a 
determination whether capacity or another performance-related feature 
justifies a different standard, DOE must consider such factors as the 
utility of the feature to the consumer and other factors DOE deems 
appropriate. Id.
    For vented heaters, the current energy conservation standards 
specified in 10 CFR 430.32(i)(2) are based on 11 product classes 
divided by equipment type (i.e., gas wall, gas floor, or gas room), 
heat circulation type (i.e., fan type or gravity type), and input 
capacity. Table III.2 lists the current product classes for vented 
heaters.

------------------------------------------------------------------------

    In the February 2019 RFI, DOE requested feedback on whether changes 
to the current vented heater product classes should be made. AHRI 
stated that changes to the existing product classes and adding new 
product classes are not necessary. (AHRI, No. 6 at p. 2) No other 
comments were received on the DHE product classes.

B. Analysis for This Notification of Proposed Determination

1. Overview of the Analysis
    As stated previously, in determining that amended standards are not 
needed, DOE must consider whether amended standards would result in 
significant conservation of energy, are technologically feasible, and 
are cost-effective as described in 42 U.S.C. 6295(o)(2)(B)(i)(II). (42 
U.S.C. 6295(m)(1)(A) and 42 U.S.C. 6295(n)(2)). An evaluation of cost-
effectiveness under 42 U.S.C. 6295(o)(2)(B)(i)(II) requires that DOE 
consider savings in operating costs throughout the estimated average 
life of the covered products in the type (or class) compared to any 
increase in the price, initial charges, or maintenance expenses for the 
covered products that are likely to result from the standard. (42 
U.S.C. 6295(n)(2) and 42 U.S.C. 6295(o)(2)(B)(i)(II)) Before potential 
energy savings and cost-effectiveness of amended standards can be 
estimated, available and working prototype technologies with the 
potential to improve energy efficiency must first be evaluated. 
Accordingly, DOE generally starts with this technology evaluation.
a. Technological Feasibility
    In evaluating potential amendments to energy conservation 
standards, DOE first conducts a market and technology assessment to 
survey the products currently available on the market and identify 
technology options (including prototype technologies) that could 
improve the efficiency of the products or equipment that are the 
subject of the rulemaking. DOE then conducts a screening analysis for 
the technologies identified, and, as a first step, determines which of 
those means for improving efficiency are technologically feasible. DOE 
considers technologies incorporated in commercially-available products 
or in working prototypes to be technologically feasible. 10 CFR part 
430, subpart C, appendix A, section 6(c)(3)(i).
    After DOE has determined that particular technology options are 
technologically feasible, it further evaluates each technology option 
in light of the following additional screening criteria: (1) 
Practicability to manufacture, install, and service; (2) adverse 
impacts on product utility or availability; (3) adverse impacts on 
health or safety, and (4) whether a proprietary technology represents a 
unique pathway to achieving a certain efficiency level. 10 CFR part 
430, subpart C, appendix A, section 6(c)(3)(ii)-(v) The technology 
options identified for this NOPD are essentially those technologies 
identified and considered for the October 2016 final determination. See 
sections III.B.3.b and III.B.3.c of this document for additional 
discussion.
    When DOE proposes to adopt an amended standard for a type or class 
of covered product, as part of its analysis, it must determine the 
maximum improvement in energy efficiency or maximum reduction in energy 
use that is technologically feasible for such a product. (42 U.S.C. 
6295(p)(1)) Accordingly, DOE determined the max-tech improvements in 
energy efficiency for vented heaters, using the design parameters for 
the most efficient products available on the market or in working 
prototypes. See section III.B.3.d of this document for further 
discussion.

[[Page 77026]]

b. Energy Savings
    In determining whether amended standards are needed, DOE must 
consider whether potential standards would result in significant 
conservation of energy. (42 U.S.C. 6295(m)(1)(A) and 42 U.S.C. 
6295(n)(2)) Congress did not define the statutory term ``significant 
conservation of energy.'' DOE recently defined a significant energy 
savings threshold in the Process Rule. 85 FR 8626, 8705 (Feb. 14, 
2020). Specifically, DOE prescribed a two-step approach that considers 
both a quad threshold value (i.e., for site energy savings calculated 
over a 30-year period) and a percentage threshold value (i.e., for 
percentage reduction in energy usage) to ascertain whether a potential 
standard satisfies the requirement of 42 U.S.C. 6295(o)(3)(B) that DOE 
may not set a standard that ``will not result in significant 
conservation of energy.'' Id.; see also section 6(b) of the Process 
Rule. As discussed, if neither threshold is met, the analysis will end, 
and DOE will propose to determine that no significant energy savings 
would likely result from setting new or amended standards. Section 
6(b)(4) of the Process Rule.
    DOE considered the energy use analysis conducted for the April 2010 
final rule, the qualitative evaluation of the potential savings in the 
October 2016 final determination, and input from stakeholders and other 
sources to evaluate the current potential for significant energy 
conservation from amended DHE standards.
c. Cost-Effectiveness
    Under EPCA's six-year-lookback review provision for existing energy 
conservation standards at 42 U.S.C. 6295(m)(1), cost-effectiveness of 
potential amended standards is a relevant consideration both where DOE 
proposes to adopt such standards, as well as where it does not. In 
making a determination of whether existing energy conservation 
standards do not need to be amended, EPCA requires DOE to consider the 
cost-effectiveness of amended standards in the context of the savings 
in operating costs throughout the estimated average life of the covered 
product compared to any increase in the price of, or in the initial 
charges for, or maintenance expenses of, the covered product that are 
likely to result from a standard. (42 U.S.C. 6295(m)(1)(A) (referencing 
42 U.S.C. 6295(n)(2))) Additionally, any new or amended energy 
conservation standard prescribed by the Secretary for any type (or 
class) of covered product shall be designed to achieve the maximum 
improvement in energy efficiency which the Secretary determines is 
technologically feasible and economically justified. (42 U.S.C. 
6295(o)(2)(A)) Cost-effectiveness is one of the factors that DOE must 
ultimately consider under 42 U.S.C. 6295(o)(2)(B) to support a finding 
of economic justification, if it is determined that amended standards 
are appropriate under the applicable statutory criteria. (42 U.S.C. 
6295(o)(2)(B)(i)(II))
    In determining cost effectiveness of potential amended standards 
for DHE, DOE considered the life-cycle cost (LCC) and payback period 
(PBP) analyses that estimate the costs and benefits to users from 
standards. The LCC is the sum of the initial price of equipment 
(including its installation) and the operating expense (including 
energy, maintenance, and repair expenditures) discounted over the 
lifetime of the equipment. The LCC analysis requires a variety of 
inputs, such as equipment prices, equipment energy consumption, energy 
prices, maintenance and repair costs, equipment lifetime, and discount 
rates appropriate for consumers. To account for uncertainty and 
variability in specific inputs (e.g., equipment lifetime and discount 
rate), DOE uses a distribution of values, with probabilities attached 
to each value.
    The PBP is the estimated amount of time (in years) it takes 
consumers to recover the increased purchase cost (including 
installation) of more-efficient equipment through lower operating 
costs. DOE calculates the PBP by dividing the change in total 
installation cost due to a more-stringent standard by the change in 
annual operating cost for the year that standards are assumed to take 
effect.
    To further inform DOE's consideration of the cost-effectiveness of 
potential amended standards, DOE may also consider the NPV of total 
costs and benefits estimated as part of the national impact analysis 
(NIA). The inputs for determining the NPV of the total costs and 
benefits experienced by consumers are: (1) Total annual installed cost, 
(2) total annual operating costs (energy costs and repair and 
maintenance costs), and (3) a discount factor to calculate the present 
value of costs and savings.
    For the determination proposed in this document, DOE considered the 
LCC and PBP analyses from the April 2010 final rule, as well as the 
evaluation in the October 2016 final determination, and information 
gathered on the current market and technologies.
d. Further Considerations
    As stated previously, pursuant to EPCA, if DOE does not issue a 
notification of determination that energy conservation standards for 
DHE do not need to be amended, DOE must issue a NOPR that includes new 
proposed standards. (42 U.S.C. 6295(m)(1)(B)) The new proposed 
standards in any such NOPR must be based on the criteria established 
under 42 U.S.C. 6295(o). (42 U.S.C. 6295(m)(1)(B)) The criteria in 42 
U.S.C. 6295(o) require that standards be designed to achieve the 
maximum improvement in energy efficiency, which the Secretary 
determines is technologically feasible and economically justified. (42 
U.S.C. 6295(o)(2)(A)) In deciding whether a proposed standard is 
economically justified, DOE must determine whether the benefits of the 
standard exceed its burdens. (42 U.S.C. 6295(o)(2)(B)(i)) DOE must make 
this determination after receiving comments on the proposed standard, 
and by considering, to the greatest extent practicable, the following 
seven statutory factors:
    (1) The economic impact of the standard on manufacturers and 
consumers of the products subject to the standard;
    (2) The savings in operating costs throughout the estimated average 
life of the covered products in the type (or class) compared to any 
increase in the price, initial charges for, or maintenance expenses of 
the covered products that are likely to result from the standard;
    (3) The total projected amount of energy (or as applicable, water) 
savings likely to result directly from the standard;
    (4) Any lessening of the utility or the performance of the covered 
products likely to result from the standard;
    (5) The impact of any lessening of competition, as determined in 
writing by the Attorney General, that is likely to result from the 
standard;
    (6) The need for national energy and water conservation; and
    (7) Other factors the Secretary of Energy (Secretary) considers 
relevant. (42 U.S.C. 6295(o)(2)(B)(i)(I)-(VII))
    As discussed in the October 2016 final determination, DOE found 
that amended standards for vented heaters would not be economically 
justified under the considerations of the seven factors prescribed in 
EPCA. 81 FR 71325, 71328-71329 (Oct. 17, 2016). For the determination 
proposed in this document, DOE has considered the previous evaluation 
of amended standards in the October 2016 final determination.
2. Unvented Heaters
    In the February 2019 RFI, DOE specifically sought comment on the 
definitions for unvented heaters, and generally sought comment on a 
number

[[Page 77027]]

of issues related to DHE (which includes both vented and unvented home 
heaters). 84 FR 6095, 6098 (Feb. 26, 2019).
    CA IOUs suggested that electric infrared heating technology be 
added to the technology options list. (CA IOUs, No. 9 at p. 1) DOE 
notes that this particular technology option is relevant to unvented 
heaters (as electric infrared heaters are not vented). However, for 
unvented heaters, including electric unvented heaters, any heat losses 
are lost to the living space in which the unit is installed. As a 
result, these heaters are nearly 100-percent efficient during the 
heating season, in that all energy consumed is converted to heat that 
ends up within the living space as useful heat, and as a result, there 
is negligible opportunity for energy savings. Therefore, DOE has 
tentatively determined not to analyze unvented electric heaters 
further. However, DOE seeks additional input on the operation of 
electric infrared heaters as compared to other types of electric 
unvented heaters, and on the comparative levels of energy consumption.
    Regarding unvented gas heaters and unvented oil heaters, the Joint 
Advocates commented in response to the RFI that DOE should consider a 
standard for unvented heaters that addresses off mode energy 
consumption. The commenters argued that models with standing pilot 
lights can waste a significant amount of energy in off mode during the 
non-heating season. (Joint Advocates, No. 7 at p. 2)
    The unvented heater test procedure, Appendix G, has provisions to 
calculate the rated output in Btu/h for gas and oil models. Under 
Appendix G, measurement of the pilot light input rate is not required 
for unvented heaters where the pilot light is designed to be turned off 
by the user when the heater is not in use and that include an 
instruction to turn off the unit is provided on the heater near the gas 
control value (e.g., by label) by the manufacturer. For unvented 
heaters with a pilot light that is not designed to be turned off when 
not in use, or that does not include an instruction to do so, the pilot 
light input rate is required to be measured, but is not used in the 
calculation of rated output. DOE reviewed the product literature for 
unvented gas and oil heaters on the market and found that most models 
that include a standing pilot light instruct the user on how to turn 
the pilot light off, and, therefore, would not be required to measure 
the pilot light consumption under the existing test procedure. As a 
result, most models are not required to measure the pilot light input 
rate. DOE will further consider whether to propose amended test 
procedures for unvented home heating equipment in the ongoing 
evaluation of the test procedure, including whether to address the 
measurement of the energy consumption and energy efficiency associated 
with standing pilot lights.\10\
---------------------------------------------------------------------------

    \10\ DOE published an RFI regarding test procedures for DHE. 84 
FR 6088 (Feb. 26, 2019). The docket for the test procedure RFI is 
available at: https://www.regulations.gov/docket?D=EERE-2019-BT-TP-0003.
---------------------------------------------------------------------------

3. Vented Heaters
    In the February 2019 RFI, DOE sought comment on a number of issued 
related to vented heaters, which are discussed in the subsections 
within this section. 84 FR 6095, 6098-6106 (Feb, 26, 2019).
a. Market Assessment
Models on the Market
    DOE has conducted a review of the vented heater market, including 
product literature and product listings in the CCMS database and AHRI 
product directory. DOE has tentatively concluded that the number of 
models offered in each of the vented heater product classes has 
continued to decrease overall since the October 2016 final 
determination, as shown in Table III.3 of this document. The model 
counts presented in Table III.3 of this document are counts of 
individual model numbers, as opposed to basic model numbers. A basic 
model can have multiple individual model numbers certified under it. 
The model counts from previous rulemakings were individual model 
numbers, so for consistency of comparison, the model counts for 2019 
that are presented in Table III.3 of this document are also in terms of 
individual model number. DOE acknowledges that, although changes in 
model counts and shipments sometimes correlate, changes to available 
model counts do not necessarily indicate a change in the number of 
units sold. For example, a model could be taken off of the market, but 
more units of another model could be sold, thereby resulting in roughly 
the same amount of sales as before the first model was taken off the 
market. Shipments of vented heaters are discussed is section III.B.3.g 
of this document.
---------------------------------------------------------------------------

    \11\ AHRI is the trade association that represents manufacturers 
of heating products. It was formed on January 1, 2008, by the merger 
of GAMA, which formerly represented these manufacturers, and the 
Air-Conditioning and Refrigeration Institute. As stated previously, 
AHRI maintains a Consumers' Directory of Certified Product 
Performance for direct heating equipment, which can be found on 
AHRI's website at: https://www.ahridirectory.org/Search/SearchHome?ReturnUrl=%2f.

    In response to the February 2019 RFI, AHRI confirmed that there are 
fewer models in the AHRI Directory now than there were at the time of 
the October 2016 final determination. (AHRI, No. 6 at p. 4) In response 
to the February 2019 RFI, AHAM and AHRI commented generally that the 
market characteristics have not changed significantly since the 
analysis was done for the October 2016 final determination. (AHAM, No. 
5 at p. 2; AHRI, No. 6 at p.1)
    The CA IOUs stated that they reviewed available models from major 
distributors and catalogs, and they identified the models available in 
each product class through an online market survey. CA IOUs provided 
the number of models they identified along with information on the AFUE 
values available. (CA IOUs, No. 8 at pp. 2-3) The number of models in 
the gas wall fan type and gravity type vented heater product classes 
identified by the CA IOUs were different than those identified by DOE 
from its review of the CCMS database and the AHRI Directory. For the 
gas wall fan type vented heater product class, CA IOUs stated they 
identified 64 products, whereas DOE identified 48 models in the CCMS 
database and 50 models in the AHRI Directory. For the gas wall gravity 
type vented heater product class, CA IOUs stated they identified 43 
products, whereas DOE identified 50 models in the CCMS database and 48 
models in the AHRI Directory. For the gas floor vented heater product 
class, CA IOUs identified 10 products which matched the number of 
models in the CCMS database and the AHRI Directory. For the gas room 
vented heater product class, CA IOUs did not provide a number for the 
identified models but did state that there were a large number 
available on the market. (CA IOUs, No. 8 at p. 2) DOE identified 19 gas 
room vented heaters in both the CCMS database and AHRI Directory.
    The discrepancies between the gas wall fan type and gas wall 
gravity type vented heater model counts identified by CA IOUs and the 
model counts identified by DOE from the CCMS database and AHRI 
Directory may have arisen from CA IOUs' review of the market through 
online sources and catalog review where the product class may not have 
been immediately apparent. The AHRI Directory provides information on 
the DHE and heat circulation types which are used to identify each 
model's product class (information which is not publicly available in 
the CCMS database). The information in the AHRI Directory is provided 
directly by AHRI-member manufacturers, and as such, products are 
classified directly by manufacturers. Similarly, the DOE CCMS database 
relies on manufacturer submissions. Manufacturers of covered products 
are required to submit to DOE a certification report certifying that 
each basic model meets the applicable energy conservation standard(s) 
before distributing in commerce any basic model. The certification 
report includes general information such as the manufacturer and model 
number, and product specific information, which for DHE includes the 
AFUE rating. Because manufacturers are legally required to submit model 
information to DOE, the CCMS database should be the most comprehensive 
listing of models available. Further, both the CCMS and AHRI database 
may be more accurate than a review of manufacturers' literature, due to 
manufacturers' familiarity with their products' classifications. The 
total model count for gas wall fan type and gas wall gravity type 
vented heaters provided by the CA IOUs is 107, and the total model 
count for the same models when examining both the CCMS database and 
AHRI Directory is 100.
    Likewise, the AFUE ranges identified by the CA IOUs also do not 
match the ranges DOE identified based on the CCMS database and AHRI 
Directory. For gas wall fan type vented heaters with input rates below 
42,000 Btu/h, CA IOUs stated that the AFUE range was between 75 and 83 
percent, while DOE identified models with AFUE values between 75 and 90 
percent. (CA IOUs, No. 8 at pp. 2-3) This suggests that the two 
condensing models on the market were not a part of CA IOUs' analysis. 
For gas wall fan type vented heaters with input rates above 42,000 Btu/
h, CA IOUs stated that the AFUE range was between 74 and 76 percent and 
that all the products they reviewed had AFUE values below the minimum 
energy conservation standard of 76 percent. (CA IOUs, No. 8 at pp. 2-3) 
DOE found that the models identified by the CA IOUs as gas wall fan 
type vented heaters with AFUE below 76 percent were gas wall gravity 
type vented heaters and listed in the CCMS database with AFUE values 
which meet the minimum energy conservation standards for the gas wall 
gravity type classes. For gas wall gravity type vented heaters with 
input rates less than or equal to 27,000 Btu/h, greater than 27,000 
Btu/h and less than or equal to 46,000 Btu/h, and greater than 46,000 
Btu/h, the AFUE ranges identified by CA IOUs were 65 to 76 percent, 65 
to 76 percent, and 69 to 71 percent, respectively. (CA IOUs, No. 8 at 
pp. 2-3) DOE identified the AFUE ranges for the given input capacities 
as 65 to 72 percent, 66 to 70 percent, and 67 to 70 percent, 
respectively. The minimum energy conservation standard for the three 
gas wall gravity type vented heater input rate ranges, from lowest to 
highest input rate, are 65, 66, and 67 percent, respectively. For gas 
wall gravity type vented heaters with input rates greater than 27,000 
Btu/h and less than or equal to 46,000 Btu/h, the minimum AFUE in the 
CA IOUs identified range (65 percent) is less than the minimum energy 
conservation standard (66 percent), suggesting that at least one model 
was misidentified.
    For gas wall gravity type vented heaters with input rates greater 
than 46,000 Btu/h, the minimum AFUE identified by CA IOUs (69 percent) 
is above the minimum energy conservation standard (67 percent), 
suggesting that not all models in this input rate range were 
identified. For gas floor vented heaters, CA IOUs identified an AFUE 
range between 57 and 70 percent across all input rate ranges. (CA IOUs, 
No. 8 at pp. 2-3) However, all gas floor vented heaters identified by 
DOE have AFUE values at the minimum energy conservation standard. The 
minimum energy conservation standards gas floor vented heaters with 
input rates less than or equal to 37,000 Btu/h and greater than 37,000 
Btu/h are 57 and 58 percent, respectively. The CA IOUs provided links 
to their 10 identified gas floor vented heaters, and the model numbers 
matched those identified by DOE which have AFUE values at the minimum 
energy conservation standard. (CA IOUs, No. 8 at pp. 2-3) Further, none 
of the sources CA IOUs provided included any efficiency or AFUE 
information. Due to various discrepancies DOE has identified in the 
model count and AFUE ranges provided by CA IOUs, DOE has tentatively 
decided to continue to use the models and AFUE values found within the 
CCMS database and AHRI Directory.
Manufacturers
    The number of manufacturers producing vented heaters increased in 
the CCMS database from four to five since the October 2016 final 
determination. This new manufacturer mainly produces hearth products 
(which are not subject to this proposed determination) but has added 
two gas wall gravity type vented heaters with input rate and AFUE 
values that are comparable to the input rate and AFUE values of other 
models available on the market, and that are similar in design. AHRI 
stated that there are six AHRI member manufacturers in the DHE

[[Page 77029]]

industry. (AHRI, No. 6 at p. 5) Upon review two of the six 
manufacturers identified by AHRI were not identified by DOE as 
manufacturers of vented heaters. Rather, DOE found that the two 
additional AHRI manufacturers produce hearth products, which as noted 
previously are not a subject of this rulemaking. The new manufacturer 
identified by DOE is not an AHRI member manufacturer and, consequently, 
was not identified by AHRI.
b. Technology Options for Efficiency Improvement
    In the February 2019 RFI, DOE listed the technology options 
considered in the previous rulemakings to increase AFUE and requested 
comment on these options and any other technology options that would be 
relevant to vented heaters. 84 FR 6095, 6099 (Feb. 26, 2019). 
Specifically, DOE identified the technologies in the following Table 
III.4 for improving the efficiency of vented heaters.

           Table III.4--Technology Options for Vented Heaters
------------------------------------------------------------------------
                           Technology options
-------------------------------------------------------------------------
Increased heat exchanger surface area.
Multiple flues.
Multiple turns in flue.
Direct vent (concentric).
Increased heat transfer coefficient.
Electronic ignition.
Thermal vent damper.
Electrical vent damper.
Power burner.
Induced draft.
Two-stage and modulating operation.
Improved fan or blower motor efficiency.
Increased insulation.
Condensing.
Condensing Pulse Combustion.
Air circulation fan.
Sealed combustion.
------------------------------------------------------------------------

    AHAM commented that technologies available for improving efficiency 
have not advanced significantly since the October 2016 final 
determination. (AHAM, No. 5 at p. 2) AHRI further stated that the use 
of the technologies that DOE identified are generally not economically 
justifiable, that consumers will purchase other types of heating 
appliances (e.g., not DHE) before purchasing vented heaters with those 
technologies, and that other technology options should not be 
considered in the analysis. In addition, AHRI stated that the inclusion 
of electronic ignition can minimize the utility of vented heaters. 
(AHRI, No. 6 at p. 3)
    During DOE's examination of the current vented heater market, DOE 
found that the available range of input rates and AFUE values of 
products available on the market have stayed largely the same since the 
October 2016 final determination. Differences in the available input 
rate and AFUE were mostly due to models being taken off the market as 
opposed to new models being added. This indicates that the technology 
options currently available are similar to those examined in both the 
April 2010 final rule and October 2016 final determination. DOE did not 
identify any additional technologies, and there were not any comments 
suggesting additional technology options for vented heaters that were 
not previously considered. Therefore, DOE used the technology options 
in Table III.4 of this document for its review of potential amended 
vented heater energy conservation standard levels in this document.
c. Screening Analysis
    In the February 2019 RFI, DOE identified and explained why four of 
the technologies on its initial list had been previously screened out: 
(1) Increased heat transfer coefficient (practicability to manufacture, 
install, and service); (2) power burner (practicability to manufacture, 
install, and service); (3) condensing pulse combustion (technological 
feasibility); and (4) improved fan or blower motor efficiency 
(practicability to manufacture, install, and service). 84 FR 6095, 
6099-6100 (Feb. 26, 2019). DOE also noted that it only considers 
potential efficiency levels achieved through the use of proprietary 
designs in the engineering analysis if they are not part of a unique 
pathway to achieve the efficiency level (i.e., if there are other non-
proprietary technologies capable of achieving the same efficiency 
level). 84 FR 6095, 6099 (Feb. 26, 2019). DOE sought comment on how 
these criteria would apply to technology options for vented heaters and 
whether the previously screened out technology options should continue 
to be screened out. 84 FR 6095, 6100 (Feb. 26, 2019).
    AHRI stated that the screening criteria are appropriate and will 
result in most, if not all, of the technology options being eliminated 
from further consideration. AHRI stated elsewhere that the technology 
options presented are generally not economically justifiable and that 
AHRI members have indicated that customers will often purchase other 
heating appliances before purchasing DHE with the listed technology 
options. AHRI further stated that incorporation of the technologies 
identified in the February 2019 RFI would require significant 
investment on the part of manufacturers in the industry. (AHRI, No. 6 
at p. 3-4) DOE notes that the five criteria for removing a technology 
option during the screening analysis are technological feasibility, 
practicability to manufacture, service or install, adverse impacts on 
consumer utility, adverse impacts on product safety, and unique-pathway 
proprietary technologies. The economic justification of a technology 
option is not considered in the screening analysis.
    In evaluating potential technology options for this notice, DOE 
maintained the list from the February 2019 RFI, as discussed in section 
III.B.3.b of this document. In addition, DOE did not find that any of 
the technology options should be screened out from consideration as 
options for improving the AFUE of vented heaters other than the four 
previously screened-out.
d. Engineering Analysis
    For the April 2010 final rule, DOE determined technology options by 
efficiency level for each of the vented heater product classes. These 
technology options are found in section 5.7 of the April 2010 final 
rule technical support document (TSD) \12\ and are reproduced in Table 
III.5 of this document. The representative input rate ranges from the 
April 2010 final rule are >42,000 Btu/h for gas wall fan type vented 
heaters, >27,000 Btu/h and <=46,000 Btu/h for gas wall gravity type 
vented heaters, >37,000 Btu/h for gas floor vented heaters, and >27,000 
Btu/h and <=46,000 Btu/h for gas room vented heaters. 75 FR 20112, 
20114 (April 16, 2010).

* Condensing gas wall fan type vented heaters exist in an input rate range that was not the representative input
  rate range in the April 2010 final rule. Thus, the max-tech level presented is theoretical for the
  representative input range, but exists in models on the market in other input ranges.
** This is a theoretical efficiency level based on the analysis for the April 2010 final rule, and is not
  available in any model currently on the market.

    The maximum available efficiency level is the highest efficiency 
model currently available on the market for that class. The max-tech 
efficiency level represents the theoretical maximum possible efficiency 
if all available design options are incorporated in a model. In some 
cases, models at the max-tech efficiency level are not commercially 
available because, although the level is technically achievable, 
manufacturers have determined that it is not economically feasible 
(either for the manufacturer to produce or for consumers to purchase). 
However, DOE seeks to determine the max-tech level for purposes of its 
analyses. The current maximum available efficiencies for the 11 
existing product classes are included in Table III.7, along with the 
maximum available efficiencies from the April 2010 final rule and those 
evaluated for the October 2016 final determination.

    In the April 2010 final rule, DOE determined max-tech efficiency 
levels using the technology options available at that time. For gas 
wall fan type vented heaters with an input rate over 42,000 Btu/h, DOE 
identified a max-tech efficiency level design with induced draft 
combustion and electronic ignition, resulting in an AFUE of 80 percent. 
For gas wall gravity type vented heaters with an input rate over 27,000 
Btu/h and up to 46,000 Btu/h, DOE identified 70 percent AFUE as a 
theoretical max-tech level, which was achievable with an improved heat 
exchanger design and electronic ignition. For gas floor vented heaters 
with an input rate over 37,000 Btu/h, DOE identified the max-tech 
efficiency level as 58 percent AFUE, which DOE stated could be reached 
using a standing pilot light and an improved heat exchanger design. For 
gas room vented heaters with an input rate over 27,000 Btu/h and up to 
46,000 Btu/h, DOE identified a theoretical max-tech efficiency level of 
83 percent AFUE, which manufacturers could achieve using an electronic 
ignition and a multiple heat exchanger design. 75 FR 20112, 20145-20146 
(April 16, 2010).
    In the October 2016 final determination, DOE noted that condensing 
gas wall fan type vented heater models with input rates at or below 
42,000 Btu/h had become available, and DOE considered this the max-tech 
level for all gas wall fan type vented heaters. Based on information 
obtained during manufacturer interviews and a manufacturer production 
cost developed through a teardown analysis performed for the proposed 
determination, DOE determined that condensing technology was not 
economically justified for gas wall fan type vented heaters at that 
time. 81 FR 21276, 21280 (April 11, 2016); 81 FR 71325, 71328-71329 
(Oct. 17, 2016).
    Since the October 2016 final determination, the highest efficiency 
condensing gas wall fan type vented heater, with an input rate at or 
below 42,000 Btu/h, available on the market has been rerated (e.g., the 
same model number has been rated with at least two different AFUE 
values between the October 2016 final determination and this NOPD) from 
an AFUE of 92 percent to an AFUE of 90 percent, which is the only 
condensing AFUE level on the market. The maximum available AFUE for gas 
wall gravity type vented heaters, with an input rate over 27,000 Btu/h 
and up to 46,000 Btu/h, increased to 70 percent, which is the max-tech 
level analyzed in the April 2010 final rule. In total, the maximum 
available AFUE decreased for two input rate ranges and increased for 
one input rate range. All other input rate ranges have the same maximum 
available AFUE as in the October 2016 final determination.
    In response to the February 2019 RFI, AHRI stated that condensing, 
multi-stage vented heaters equipped with combustion and circulating 
fans should be considered the max-tech technology option. (AHRI, No. 6 
at p. 4) The commenter added that condensing vented heaters continue to 
be significantly more expensive to produce than non-condensing models 
and are by and large not economically justified. AHRI also stated that 
only one manufacturer produces condensing vented heaters and that there 
are only two models listed in the AHRI Directory. Id. Lastly, AHRI 
generally recommended against the use of the maximum available 
efficiency levels as possible energy conservation standards. Id.
    Joint Advocates estimated that condensing gas wall fan type vented 
heaters would reduce energy use by about 17 to 18 percent over models 
at the baseline. (Joint Advocates, No. 7 at p. 2) CA IOUs stated that 
higher condensing efficiencies could be achieved through the use of 
microprocessor controls, a two-stage heat exchanger, and multi-speed 
blowers for venting and air circulation. According to the CA IOUs, 
there are two manufacturers of condensing vented heaters, so those 
commenters recommended that DOE consider the condensing technology 
option. CA IOUs asserted that as this option gains popularity with 
manufacturers, there is the likelihood of increased market share 
leading to larger production volumes and a decrease in consumer costs 
due to economies of scale and increased competition. (CA IOUs, No. 8 at 
p. 4)
    As noted, AHRI stated that there is one manufacturer of condensing 
gas wall fan type vented heaters, whereas the CA IOUs stated that there 
are two manufacturers and supplied manufacturer literature from the two 
manufacturers. (AHRI, No. 6 at p. 4; CA IOUs, No. 8 at p. 4) To assess 
this discrepancy, DOE reviewed the supplied literature and found that 
the literature was last updated in 2017 and could not find the models 
on the manufacturer's website. Consequently, DOE has tentatively 
determined that there is only one manufacturer of condensing gas wall 
fan type vented heaters on the market at the time of this NOPD.
    Consistent with comments and the evaluation in the October 2016 
final determination, DOE considers condensing technology to be the 
``max-tech'' levels for gas wall fan type vented heaters.
    As explained in section II.B.6 of this document, DOE published the 
July 2019 NOPIR in the Federal Register which proposed to interpret 
EPCA to provide that adoption of energy conservation standards that 
would limit the market to natural gas and/or propane furnaces, water 
heaters, or similarly-situated products/equipment (where permitted

[[Page 77032]]

by EPCA) that use condensing combustion technology would result in the 
unavailability of a performance-related feature within the meaning of 
42 U.S.C. 6295(o)(4) and 42 U.S.C. 6313(a)(6)(B)(iii)(II)(aa) and 42 
U.S.C. 6316(a). 84 FR 33011, 33021 (July 19, 2019). In light of the 
July 2019 NOPIR, DOE further investigated the venting options 
associated with condensing and non-condensing DHE. Categories of 
venting appliances are defined in the 2018 National Fire Protection 
Association (NFPA) 54/American National Standards Institute (ANSI) 
Z223.1 National Fuel Gas Code, titled ``NFPA 54 National Fuel Gas 
Code'' (NFPA 54-2018). Currently, the only models on the market using 
condensing technology are gas wall fan type vented heaters. Through an 
examination of these products' installation literature, condensing gas 
wall fan type vented heaters are installed using Category IV \13\ 
venting. Non-condensing gas wall fan type vented heaters are typically 
installed using either Category I \14\ or Category III \15\ venting. 
Therefore, products using condensing technology require a different 
venting system (i.e., Category IV venting) than non-condensing DHE 
(which typically use either Category I or Category III venting). As a 
result, DHE are similarly situated relative to residential furnaces and 
commercial water heaters, in that replacing an existing non-condensing 
vented heater with a vented heater that uses condensing technology may 
require significant changes to the existing vent system. As such, DOE's 
proposed interpretation in the July 2019 NOPIR, if finalized, would 
apply to DHE.
---------------------------------------------------------------------------

    \13\ NFPA 54-2018 defines a ``Category IV Vented Appliance'' as 
an appliance that operates with a positive vent static pressure and 
with a vent gas temperature that can cause excessive condensate 
production in the vent.
    \14\ NFPA 54-2018 defines a ``Category I Vented Appliance'' as 
an appliance that operates with a non-positive vent static pressure 
and with a vent gas temperature that avoids excessive condensate 
production in the vent.
    \15\ NFPA 54-2018 defines a ``Category III Vented Appliance'' as 
an appliance that operates with a positive vent static pressure and 
with a vent gas temperature that avoids excessive condensate 
production in the vent.
---------------------------------------------------------------------------

    Under the proposed interpretation in the July 2019 NOPIR, DOE would 
consider whether non-condensing combustion technology justified a 
separate product class under 42 U.S.C. 6296(q). If DOE determined that 
such technology did justify a separate product class for DHE, DOE would 
consider establishing separate standards for a condensing DHE product 
class and a non-condensing DHE product class (or through classes that 
maintain venting compatibility, as DOE determines appropriate). As a 
result, although DOE considers condensing technology to represent the 
max-tech design for gas wall fan type vented heaters, if a separate 
product class were to be established for condensing gas wall fan type 
vented heaters, there would be no additional energy savings associated 
with the max-tech level, as discussed in sections III.B.3.e and 
III.B.3.h of this document.
    National Grid stated that it found a gas floor vented heater with a 
rated AFUE of 70 percent and suggested that the minimum AFUE for gas 
floor vented heaters should be increased. (National Grid, No. 9 at p. 
1) However, all of the gas floor vented heater models that DOE found in 
the CCMS database and AHRI Directory have rated AFUE values at the 
baseline (i.e., 57 percent for models at or below 37,000 Btu/h and 58 
percent for models above 37,000 Btu/h). DOE was unable to find the 
model identified by National Grid in its product research, and the 
Department seeks additional information regarding the highest available 
efficiency and maximum possible efficiency for gas floor vented 
heaters. Thus, for the purposes of this analysis, DOE tentatively 
considers the maximum available AFUE values found in Table III.7 of 
this document to be the max-tech efficiency levels.
    The Joint Advocates and the CA IOUs encouraged DOE to perform an 
engineering analysis on all 11 product classes of vented heaters. 
(Joint Advocates, No. 7 at p. 2; CA IOUs, No. 9 at p. 2) The Joint 
Advocates also stated that there is significant market availability of 
gas wall vented heaters, both fan type and gravity type, which exceed 
the current energy conservation standard levels. (Joint Advocates, No. 
7 at p. 1) DOE agrees that there are models on the market which exceed 
the current energy conservation standards, but as discussed in this 
section, the technology options have not changed significantly since 
the April 2010 final rule and October 2016 final determination. Because 
the technology options have not changed significantly, the energy use 
of all vented heaters remains approximately the same (see section 
III.B.3.e of this document). As discussed in section III.B.3.e of this 
document, DOE has tentatively determined that at max-tech the potential 
energy savings resulting from amended standards, set at levels based on 
the technology options analyzed during the April 2010 final rule and 
October 2016 final determination, would not result in significant 
energy savings. Furthermore, as discussed in section III.C.2 of this 
document, DOE has tentatively determined that the potential benefits 
from amended standards would be outweighed by burdens on manufacturers, 
in particular, small business manufacturers, as vented heater shipments 
have previously declined, and there is no evidence that shipments have 
increased since the October 2016 final determination. As such, a full 
engineering analysis of all 11 product classes of vented heaters is not 
necessary.
Manufacturer Production Costs
    After establishing the efficiency levels in the April 2010 final 
rule, DOE estimated the manufacturer production cost (MPC) of attaining 
each efficiency level based on the technology options identified for 
that level. The MPC takes into account the costs for material, labor, 
depreciation, and overhead. These values were developed based on 
product teardowns that generated bills of materials for all components 
and manufacturing processes required to manufacture vented heaters at a 
given efficiency level for each product class. DOE uses these bills of 
material, along with information on material and component prices, 
costs for labor, depreciation, and overhead to derive the MPC. In 
development of the April 2010 final rule, manufacturer interviews were 
conducted to verify the accuracy of the inputs to DOE's analysis of 
MPCs (e.g., material prices, labor rates) and the resulting MPCs. 75 FR 
20112, 20147-20148 (April 16, 2010).
    DOE reviewed its April 2010 final rule engineering analysis to 
determine whether the results are still valid in the context of the 
current market. As the technology options have not changed 
significantly since the April 2010 final rule and the market conditions 
for manufacturers remains substantially the same as the previous 
rulemaking (i.e., production volumes remain similar or slightly lower 
than previously projected, while material prices and labor rates are 
also similar), DOE has tentatively determined that the engineering 
analysis performed during the April 2010 final rule is still valid. DOE 
also reviewed retail prices for models currently available on the 
market and found that the current retail prices are comparable to those 
published in chapter 8, section 8.2.3.5 of the April 2010 final rule 
TSD, when adjusted for inflation. Because DOE has not found 
distribution channels or mark-ups to have changed since April 2010, the 
similarity of the predicted retail prices in the April 2010 final rule 
analysis to those of current products indicates that the manufacturer 
production costs are

[[Page 77033]]

also likely to be unchanged from the April 2010 final rule analysis.
e. Energy Use Analysis
    Table III.8 presents the average energy consumption, from section 
7.3.6 of the April 2010 final rule TSD, for each vented heater product 
class and efficiency level. DOE has tentatively concluded that the 
current average energy consumption for these vented heaters is 
comparable to the estimates developed for the April 2010 final rule and 
relied on in the October 2016 final determination, as the technology 
options at each efficiency level have not changed substantially.

  analysis.

    As discussed in section III.B.3.d of this document, in the event 
that amended energy conservation standards are economically justified 
for gas wall fan type vented heaters at a level which would require 
condensing technology, then at that time, separate product classes 
would likely have to be considered to effectively separate non-
condensing and condensing technologies in order to preserve non-
condensing products, consistent with the proposals in the July 2019 
NOPIR and September 2020 SNOPIR. Also as stated in section III.B.3.d of 
this document, there is only one available condensing AFUE level on the 
market, which is identified as the max-tech level. As such, the 
baseline AFUE for a potential condensing product class would be set at 
the only available AFUE level, and there would be no potential for 
energy savings in a condensing gas wall fan type vented heater product 
class, so, therefore, DOE has not presented energy use values for 
condensing gas wall fan type vented heaters.
f. Life-Cycle Cost and Payback Period Analysis
    LCC is the total consumer expense over the life of an appliance, 
including the total installed cost and operating costs (including 
energy expenditures, maintenance, and repair). DOE discounts future 
operating costs to the time of purchase, and sums them over the 
lifetime of the product.
    The total installed cost is determined by combining the 
installation cost with the equipment price. The equipment price is 
determined using the MPC and applying a manufacturer mark-up, a 
wholesaler mark-up, a mechanical contractor mark-up, and sales tax.\16\ 
As presented in section III.B.3.d of this document, DOE has tentatively 
determined that the MPC has not changed significantly since the April 
2010 final rule. DOE has also tentatively concluded that the average 
mark-ups, sales taxes, and installation costs are comparable to the 
estimates developed for the April 2010 final rule. Therefore, the total 
installed costs are estimated to have remained approximately the same, 
as compared to the April 2010 final rule, for products that are still 
on the market, as the technology options have not changed. DOE 
additionally estimates that the total installed cost for the 90-percent 
AFUE gas wall fan type vented heater would be considerably higher 
compared to lower efficiency gas wall fan type vented heaters, since 
there are considerable development and production costs (as discussed 
in section III.B.3.d of this document), as well as additional 
installation costs.
---------------------------------------------------------------------------

    \16\ For new construction, builder mark-up is also included. For 
the April 2010 final rule, the new construction market shares are 10 
percent for vented gas wall fan, vented gas wall gravity, and vented 
gas room heaters, and 0 percent for vented gas floor furnace 
heaters.
---------------------------------------------------------------------------

    The annual operating cost is determined by the energy consumption 
of vented heaters, the energy prices of the fuel used, and any repair 
and maintenance costs that would be required. DOE has tentatively 
determined that the energy consumption (as discussed in section 
III.B.3.e of this document) and repair and maintenance costs associated 
with each efficiency level have not changed significantly from that in 
the April 2010 final rule for the vented heaters that are still on the 
market, as the technology options have not changed. DOE additionally 
estimates that the average energy consumption for the 90-percent AFUE 
gas wall fan type vented heater would be proportionally lower compared 
to the 80-percent AFUE gas wall fan type vented heaters, and repair and 
maintenance costs would be higher than for the 80-percent AFUE gas wall

[[Page 77034]]

fan type vented heaters. To assess the impact of energy prices, DOE 
compared the April 2010 final rule's average energy prices for 2013 
(i.e., the starting year in the analysis) to a likely starting year if 
DOE performed a revised analysis in a new rulemaking. The April 2010 
final rule used Energy Information Administration's (EIA) Annual Energy 
Outlook (AEO) 2010 energy price trends.\17\ To assess the impact of 
updated energy price estimates, DOE used EIA's AEO 2020 energy price 
trends to estimate the energy prices in 2027,\18\ the expected 
compliance year for the updated analysis.\19\ DOE has found that both 
natural gas and propane prices are significantly lower in 2027 ($10.99/
MMBtu in 2019$ and $28.20/MMBtu in 2019$, respectively) compared to the 
2013 natural gas and propane prices used in the April 2010 final rule 
($13.31/MMBtu in 2019$ and $32.71/MMBtu in 2019$, respectively).\20\ 
Additionally, the 30-year trends are comparable in the two AEO 
editions. Due to comparable energy use and lower energy prices, DOE has 
tentatively determined that the annual operating cost of vented heaters 
has either decreased or not changed significantly from that estimated 
in the April 2010 final rule.

Administration, Annual Energy Outlook 2010 with Projections to 2035

(Last accessed August 13, 2020).
    \18\ For purposes of the updated analysis, DOE estimated 2027 as 
the first year of compliance by assuming that the publication of a 
potential final rule would occur by 2022 and any amended standards 
would apply to DHEs manufactured 5 years after this date. (42 U.S.C. 
6295(m)(4)(A)(ii)).

    \20\ For the April 2010 final rule, the fraction of propane 
installations is 12 percent for vented gas wall fan and vented gas 
wall gravity, 9 percent for vented gas floor furnace heaters, and 38 
percent for vented gas room heaters.
---------------------------------------------------------------------------

    As vented heaters have not significantly changed since the April 
2010 final rule, DOE has tentatively determined that the product 
lifetime has remained largely the same. DOE has also tentatively 
determined that residential discount rates have not changed 
significantly from those in the April 2010 final rule.
    Because the total installed costs are estimated not to have changed 
significantly, and operating costs are estimated to be comparable, DOE 
has tentatively determined that the LCC savings for each efficiency 
level of vented heaters are similar to the estimates in the April 2010 
final rule. Further, DOE has tentatively determined that the relative 
comparisons between each efficiency level for each product class remain 
unchanged and that the conclusions from the April 2010 final rule and 
October 2016 final determination are still applicable.
    The PBP is the amount of time it takes the consumer, in a typical 
case, to recover the estimated higher purchase expense of more energy-
efficient products through lower operating costs. Numerically, the PBP 
is the ratio of the increase in purchase expense (i.e., due to a more 
energy-efficient design) to the decrease in annual operating 
expenditures. This type of calculation is known as a ``simple'' payback 
period, because it does not take into account changes in operating 
expense over time or the time value of money (i.e., the calculation is 
done at an effective discount rate of zero percent). Payback periods 
are expressed in years. Payback periods greater than the life of the 
product indicate that the increased total installed cost is not 
recovered by the reduced operating expenses.
    As previously stated, DOE has estimated that the total installed 
costs have not changed significantly, and operating costs are 
comparable to the April 2010 final rule results. Therefore, DOE has 
tentatively determined that the ``simple'' payback period for each 
efficiency level of vented heaters is similar to the ``simple'' payback 
period results from the April 2010 final rule. Further, DOE has 
tentatively determined that the relative comparisons between each 
efficiency level for each product class remain unchanged and that the 
conclusions from the April 2010 final rule and October 2016 final 
determination are still applicable.
g. Shipments
    In the February 2019 RFI, DOE stated that from the April 2010 final 
rule, the Department has vented heater historical shipment data from 
AHRI for gas wall vented heaters from 1990 to 1998 and from 2000 to 
2006, for gas floor vented heaters from 1990 to 2007, and for gas room 
vented heaters from 1990 to 2005. DOE also has limited disaggregated 
shipments for fan type and gravity type gas wall vented heaters and by 
input capacity. DOE requested comment on the annual sales data (i.e., 
number of shipments) for each vented heater product class from 2008-
2018. 84 FR 6095, 6104-6105 (Feb. 26, 2019).
    AHRI stated that it was conducting a special data collection to 
gather shipment data for each vented heater product class from 2016-
2018, and that these data will be provided to DOE at a later date. AHRI 
also stated that shipment data from 2008-2015 was provided in response 
to the NOPD for direct heating equipment published in 2016. (AHRI, No. 
6 at p. 4)
    In 2016, AHRI presented data showing the percentage change in total 
shipments for the years 2010-2015 compared with the total shipments 
over the period 2001-2006, estimating that gas wall vented heater 
shipments were 21 percent less, that direct vent gas wall vented heater 
(a form of gas wall vented heater) shipments were 31 percent less, and 
that gas room vented heater shipments were 44 percent less.\21\ AHRI 
did not have an active statistics program for gas floor vented heaters 
and was attempting to collect annual shipments information for recent 
years through a special data collection.
---------------------------------------------------------------------------

    \21\ AHRI Comment to the NOPD for Direct Heating Equipment 
published in 2016 (June 10, 2016) (Comment No. 7) (Available at: 
https://www.regulations.gov/document?D=EERE-2016-BT-STD-0007-0007) 
(Last accessed Aug. 13, 2020).
---------------------------------------------------------------------------

    At this time, AHRI has not submitted data for the 2016-2018 time 
period. However, DOE will consider any additional data submissions from 
AHRI (or other interested parties) when making the final determination 
with respect to whether amended standards for DHE are justified.
h. National Energy Savings
    As explained in sections III.B.3.d through III.B.3.g of this 
document, the technology options, energy use, and shipments for DHE 
have not changed significantly since the April 2010 final rule and 
October 2016 final determination. Accordingly, the national energy 
savings are expected to be largely the same as the national energy 
savings projected in the April 2010 final rule. In the April 2010 final 
rule, DOE estimated that the max-tech TSL (TSL 6) would result in an 
additional 0.13 quads of site energy savings over 30 years, as compared 
to the adopted TSL (i.e., the current standard levels).\22\ The site 
energy

[[Page 77035]]

savings from the max-tech TSL represent approximately a six-percent 
reduction compared to the total 30-year site energy consumption, as 
compared to the current standard levels.\23\
---------------------------------------------------------------------------

    \22\ DOE used the April 2010 final rule National Impact Analysis 
(NIA) spreadsheet for DHE to calculate the site energy savings 
difference between the max-tech level (TSL 6) and current standard 
level (then TSL 2). The site energy savings are available in the 
``National Impacts Summary'' worksheet for each product class. The 
site energy savings calculation was adjusted to take into account 
the site energy savings over 30 years of product shipments (2013-
2042) and to include the full lifetime of products shipped over the 
30-year period (2013-2042). The published version of the DHE NIA 
spreadsheet only accounted for site energy savings from 2013-2042. 
The resulting 30-year site energy savings per product class are: 
0.02 quads for gas wall fan type vented heaters, 0.07 quads for gas 
wall gravity type vented heaters, 0.00 quads for gas floor vented 
heaters, and 0.04 quads for gas room vented heaters. The DHE NIA 
spreadsheet (published March 23, 2010) (Available at: https://www.regulations.gov/document?D=EERE-2006-STD-0129-0148) (Last 
accessed Aug. 13, 2020).
    \23\ DOE used the April 2010 final rule NIA spreadsheet for DHE 
to calculate the total 30-year site energy consumption at the 
current standard levels (then TSL 2). The ``Base Case Consumption'' 
worksheet is used to calculate the total site energy consumption at 
the current standard levels for each product class. This worksheet 
includes the total ``source energy (Quads)'' per product class. DOE 
converted the total source energy to site energy by removing the 
site-to-source factors (which come from the ``EnergyPrices 
SitetoSource'' worksheet) from the calculation. The site energy 
consumption calculation was then expanded to take into account the 
site energy consumption over 30 years of product shipments (2013-
2042) and include the full lifetime of products shipped over the 30 
year period (2013-2042), to match the site energy savings 
calculation. Finally, the totals per product class were adjusted to 
take into account the energy savings for the current standard (then 
TSL 2). The resulting 30-year site energy consumption totals per 
product class are: 0.55 quads for gas wall fan type vented heaters, 
1.30 quads for gas wall gravity type vented heaters, 0.02 quads for 
gas floor vented heaters, and 0.24 quads for gas room vented 
heaters. The 0.13 quads of 30-year site energy savings from the max-
tech TSL are then divided by the resulting total value of 2.11 quads 
for the 30-year site energy consumption at the current standard 
levels, which results in the 6-percent value.
---------------------------------------------------------------------------

    The April 2010 final rule did not contemplate or include a TSL with 
specific provisions for a condensing gas wall fan type vented heater. 
As discussed in section III.B.3.b of this document, pursuant to DOE's 
tentative interpretation from the July 2019 NOPIR, amending energy 
conservation standards to a level which would require condensing 
technology would result in the unavailability of a performance-related 
feature within the meaning of 42 U.S.C. 6295(o)(4). 84 FR 33011, 33021 
(July 11, 2019). As such, when evaluating energy savings from potential 
energy conservation standards, separate non-condensing and condensing 
product classes are investigated as a possible outcome of the Gas 
Industry Petition. DOE identified one manufacturer of condensing gas 
fan type vented heaters which produces two models at 90-percent AFUE. 
Because there was only one efficiency level available on the market and 
analyzed at the condensing level, there would be no potential 
additional energy savings from setting a condensing level for the 
divided gas wall fan type vented heater product class.
i. Manufacturer Impacts
December 2009 NOPR
    As stated in section II.B.3.b of this document, in the NOPR that 
preceded the April 2010 final rule, DOE proposed to amend standards for 
vented heaters to TSL 3. 74 FR 65852, 65973 (Dec. 11, 2009). In 
response to that proposal, DOE received several comments expressing 
concerns that:
    <bullet> Shipments of vented heaters were low, and, therefore, 
potential energy savings were low;
    <bullet> Low shipments would make it difficult for manufacturers to 
recoup the costs to comply with amended standards;
    <bullet> Product offerings may be limited as a response to amended 
standards;
    <bullet> Manufacturers may exit the industry as a result of amended 
standards;
    <bullet> Employment may be negatively impacted due to reduced 
product lines and insufficient return on investment.

75 FR 20112, 20218 (April 16, 2010).
April 2010 Final Rule
    In the April 2010 final rule, DOE additionally found that the 
industry had gone through considerable consolidation due to decreased 
shipments, that product lines were primarily maintained to provide 
replacement products, and that some small business manufacturers could 
be disproportionately affected by a more-stringent standard. 75 FR 
20112, 20199, and 20218 (April 16, 2010). As mentioned in section 
III.B.3.g of this document, the April 2010 final rule presented a trend 
of declining annual shipments throughout the 30-year analysis period. 
As discussed in section II.B.2.b of this document, DOE ultimately 
adopted standards at TSL 2 for vented heaters, which was one TSL below 
the proposed level. In rejecting proposed TSL 3, DOE concluded that the 
benefits of higher potential standard levels would be outweighed by the 
economic burden on some consumers, the large capital conversion costs 
that could result in a large reduction in INPV for the manufacturers of 
vented heaters, and the potential for small business manufacturers of 
vented heaters to reduce their product offerings or to be forced to 
exit the market completely, thereby reducing competition in the vented 
heater market. 75 FR 20112, 20218-20219 (April 16, 2010).
October 2016 Final Determination
    In the April 2016 proposed determination that preceded the October 
2016 final determination, DOE tentatively determined that the 
conclusions presented in the April 2010 final rule were still valid. 81 
FR 21276, 21281 (April 11, 2016). Further, DOE has found that the 
number of models offered in each of the vented heater product classes 
decreased in the time between the April 2010 final rule and the October 
2016 final determination, which indicated that the vented heater market 
was shrinking and product lines were mainly maintained as replacements 
for current vented heater products. 81 FR 71325, 71327 (Oct. 17, 2016).
    In the October 2016 final determination DOE noted that the number 
of manufacturers declined from six to four, indicating consolidation in 
the vented heater industry. 81 FR 71325, 71328 (Oct. 17, 2016).
Current Analysis of Manufacturer Impacts
    In DOE's most recent review of the market, a total of five 
manufacturers were identified within the vented heater industry, four 
of which are domestic small businesses. In the February 2019 RFI, DOE 
requested comment on annual sales data for each vented heater product 
class from 2008-2018. 84 FR 6095, 6105 (Feb. 26, 2019). DOE did not 
receive any comment or information regarding the number and 
classification of manufacturers presented in the February 2019 RFI and, 
therefore, considers its previous analysis of industry shipments to 
still be valid. DOE also did not receive any comments or data 
suggesting that DOE's analysis of the DHE market in the April 2016 NOPD 
was inaccurate. Because the market conditions are substantially the 
same as when DOE considered manufacturer impacts for the April 2010 
final rule and October 2016 final determination, DOE tentatively 
concludes that manufacturers would likely face similar impacts under 
more-stringent standards as those previously discussed.
4. Other Issues
a. Fuel Switching and Full-Fuel-Cycle
    NPGA urged DOE to analyze the potential of fuel switching and 
correlated effects on energy efficiency. (NPGA, No. 3 at p. 1) The 
commenter requested that DOE utilize a full-fuel-cycle (FFC) analysis 
when calculating energy consumption across all product classes and 
energy types, instead of utilizing a site energy analysis to determine 
whether to amend the energy standards for DHE. Id. NPGA further stated 
that unless DOE assesses the potential of fuel-switching, it would be 
prejudicing some energy sources. Id.
    Because consumers are sensitive to the cost of heating equipment, a 
standard level that significantly increases purchase price may induce 
some consumers to switch to a different heating product than they would 
have otherwise installed (i.e., in the case

[[Page 77036]]

where no new standards are established). In the April 2010 final rule, 
DOE was unable to find any data it could use to estimate the extent of 
fuel and product switching in its analysis. 75 FR 20112, 20165 (April 
16, 2010). As stated, the April 2010 final rule analysis is part of 
DOE's consideration for the determination proposed in this document. 
DOE uses FFC measures of energy use and greenhouse gas and other 
emissions in the national impact analyses and emissions analyses 
included in future energy conservation standards rulemakings. See 77 FR 
49701 (August 17, 2012). As previously explained in the context of 
rulemakings for other products, it would not be appropriate to 
incorporate FCC in an energy efficiency metric for energy conservation 
standards. See 81 FR 2628, 2639 (Jan. 15, 2016). First, EPCA provides 
that ``energy conservation standards'' must prescribe a ``minimum level 
of energy efficiency'' or a ``maximum quantity of energy use''; the 
statute subsequently provides that ``energy use'' is the quantity of 
energy directly consumed by a consumer product at the point of use, and 
it defines ``energy efficiency'' as the ratio of useful heat output of 
services from a consumer product to the energy use of such product. (42 
U.S.C. 6291(4)-(6)) Moreover, the mathematical adjustment to the site-
based energy descriptor to calculate an FFC value relies on information 
that is updated annually. If DOE were to include such an adjustment to 
the energy conservation standard, DOE would be required to update 
standards (or applicable test procedure) annually.
b. Environmental Analysis, Market Failures, and Market-Based Compliance
    PI NYU recommended that DOE consider the environmental costs when 
analyzing the national impact and selecting the maximum economically 
justified efficiency level. PI NYU further stated that the benefits 
from greenhouse gas emissions reductions should be considered and that 
global, as opposed to domestic-only, estimates of the social cost of 
greenhouse gas reduction should be used in the national impact 
analysis. (PI NYU, No. 4 at p. 2)
    In response, DOE notes that its rulemaking analyses include 
consideration of environmental impacts resulting from potential amended 
standards. In the April 2010 final rule, DOE performed an environmental 
assessment and considered the benefits resulting from reduced 
emissions. 75 FR 20112, 20176-20180 (April 16, 2010). Since that time, 
new legal authority has impacted DOE's approach to environmental 
analysis in regulatory rulemaking. Specifically, section 5(c) of 
Executive Order (E.O.) 13783, ``Promoting Energy Independence and 
Economic Growth,'' 82 FR 16093 (March 31, 2017), directs agencies to 
maintain consistency with the guidance contained in the Office of 
Management and Budget's Circular A-4 (Sept. 17, 2003) when monetizing 
the value of greenhouse gas emissions resulting from regulations, 
including with respect to consideration of domestic versus 
international impacts and appropriate discount rates. Section E.1 of 
OMB Circular A-4 provides that ``analysis should focus on benefits and 
costs that accrue to citizens and residents of the United States,'' and 
it further provides that ``[w]here you choose to evaluate a regulation 
that is likely to have effects beyond the borders of the United States, 
these effects should be reported separately.'' Accordingly, DOE has 
structured its environmental assessment and regulatory analyses so as 
to conform to these legal requirements.
    The Joint Advocates stated that DHE are largely used in older 
homes, many of which may be occupied by renters. The commenters stated 
that the landlord purchases the heating equipment, while the tenant 
typically pays the heating bill; therefore, there is no financial 
incentive for the person buying the DHE in these situations to purchase 
efficient units. (Joint Advocates, No. 7 at p. 2) DOE tentatively 
agrees with the Joint Advocates that when a landlord purchases heating 
equipment and the tenant pays the heating bill, there is no financial 
incentive for the landlord to purchase a more-efficient product.
    PI NYU resubmitted comments originally submitted in response to an 
energy conservation program design RFI published in the Federal 
Register on November 28, 2017. 82 FR 56181. These comments discussed 
the addition of market-based compliance flexibilities such as credit 
trading, feebates, or intra-firm averaging to the Appliance Standards 
Program.
    In the present document in which DOE is determining whether 
standards for DHE need to be amended, EPCA requires DOE to consider the 
technological feasibility of amended standards, whether such standards 
would result in a significant conservation of energy, and whether such 
standards would be cost-effective. (42 U.S.C. 6295(m)(1)(A); 42 U.S.C. 
6295(n)(2)) As such, the standards evaluated for the purpose of this 
proposed determination are the current energy conservation standards 
and standards at more-stringent levels, not potential market-based 
compliance strategies.
c. Product Labeling
    National Grid stated that many gas floor vented heaters were listed 
online without their associated AFUE value and recommended that AFUE 
should be indicated on all product specifications so that consumers can 
see the efficiency of the product compared to the range of products on 
the market. (National Grid, No. 9 at p. 1) DOE notes that all covered 
DHE must be certified to DOE under 10 CFR 429.22, and the associated 
AFUE ratings are included in the CCMS database.\24\ Representations of 
AFUE are not required in product literature, but representations of 
efficiency other than the AFUE metric established by DOE are not 
allowed. (See 42 U.S.C. 6293(c)(1))

d. Standard Level Recommendations
    In response to the February 2019 RFI, DOE received several comments 
opining on the appropriate course of action for DHE energy conservation 
standard levels. AHAM argued that the burdens outweigh the benefits of 
increasing energy conservation standards, while AHRI stated that the 
conclusion that amended standards for DHE are not economically 
justified remains true today. (AHAM, No. 5 at p. 2; AHRI, No. 6 at p.1)
    NEEA stated it supports increasing energy conservation standards 
when there are technology options available, arguing that vented 
heaters are typically inefficient when compared to other heating 
options (i.e., non-DHE heating products). (NEEA, No. 10 at p. 1) NEEA 
encouraged DOE to increase energy conservation standards for gas wall 
vented heaters, and that organization specifically suggested a level of 
80-percent AFUE for gas wall fan type vented heaters due to the high 
number of models available. (NEEA, No. 10 at p. 1) PI NYU stated that 
DOE should continue to select the maximum energy conservation standard 
level that is technologically feasible and cost-benefit justified. (PI 
NYU, No. 4 at p. 16)

C. Proposed Determination

    After carefully considering the comments on the February 2019 RFI 
and the available data and information, DOE has tentatively determined 
that energy conservation standards for DHE do not need to be amended, 
for the reasons explained in the paragraphs immediately following. DOE 
will consider all comments received on this proposed determination 
prior to issuing

[[Page 77037]]

the next document in this rulemaking proceeding.
1. Unvented Heaters
    As discussed in sections II.B.2 and III.B.1 of this document, the 
efficiency inherent with unvented electric heaters provides negligible 
opportunity for energy savings, because any heat loss of the product is 
transferred to the conditioned space and not wasted. DOE examined the 
market for unvented gas heaters and unvented oil heaters and found that 
most models on the market have instructions to turn the pilot light off 
and, thus, would not be required to measure the standing pilot light 
input rate. For these reasons, consistent with previous rulemakings in 
which it has addressed unvented heaters, DOE has tentatively determined 
that standards for unvented heaters are not needed.
2. Vented Heaters
    For vented heaters, DOE analyzed each product class--gas wall fan 
type, gas wall gravity type, gas floor, and gas room--separately in the 
market and technology assessment (sections III.B.3.a and III.B.3.b of 
this document), the screening analysis (section III.B.3.c of this 
document), the engineering analysis (section III.B.3.d of this 
document), the LCC and PBP analysis (section III.B.3.f of this 
document), and the shipments analysis (section III.B.3.g of this 
document), and the Department evaluated all vented heaters together in 
the energy use analysis (section III.B.3.e of this document), the 
national energy savings analysis (section III.B.3.h of this document), 
and the manufacturer impact analysis (section III.B.3.i of this 
document) when making a determination of whether amended standards are 
justified under EPCA.
a. Technological Feasibility
    EPCA mandates that DOE consider whether amended energy conservation 
standards for vented heaters would be technologically feasible. (42 
U.S.C. 6295(m)(1)(A) and 42 U.S.C. 6295(n)(2)(B)) For gas floor vented 
heaters, as discussed in section III.B.3.d of this document, the 
maximum available efficiency level on the market is at the baseline 
efficiency level (i.e., the current standard). Since there are no 
models available on the market above baseline and DOE is unaware of any 
prototype designs that have demonstrated higher efficiencies for gas 
floor vented heaters, DOE tentatively concludes that more-stringent 
standards for gas floor vented heaters are not technologically 
feasible.
    DOE has tentatively determined that there are technology options 
that would improve the efficiency of gas wall fan type vented heaters, 
gas wall gravity type vented heaters, and gas room vented heaters. 
These technology options are being used in commercially available gas 
wall fan type vented heaters, gas wall gravity type vented heaters, and 
gas room vented heaters and, therefore, are technologically feasible. 
(See section III.B.3.b of this document for further information.) 
Hence, DOE has tentatively determined that amended energy conservation 
standards for gas wall fan type vented heaters, gas wall gravity type 
vented heaters, and gas room vented heaters are technologically 
feasible.
b. Cost-Effectiveness
    As the next step in the agency's analysis, EPCA requires DOE to 
then consider whether amended energy conservation standards for gas 
wall fan type vented heaters, gas wall gravity type vented heaters, and 
gas room vented heaters would be cost-effective through an evaluation 
of the savings in operating costs throughout the estimated average life 
of the covered product compared to any increase in the price of, or in 
the initial charges for, or maintenance expenses of the covered 
products which are likely to result from the amended standard. (42 
U.S.C. 6295(m)(1)(A), 42 U.S.C. 6295(n)(2)(C), and 42 U.S.C. 
6295(o)(2)(B)(i)(II)) As discussed in sections II.B.2.b and III.B.3.f 
of this document, DOE determined that the LCC and PBP analyses of TSL 
3, the TSL immediately above the level adopted as a Federal standard 
(and which was proposed in the October 2009 NOPR and rejected in the 
April 2010 final rule), as evaluated in the April 2010 final rule, 
suggested that initial costs outweighed the consumer benefits. See also 
81 FR 71325, 71327 (Oct. 17, 2016). DOE has tentatively determined that 
the LCC and PBP analyses conducted for the April 2010 final rule remain 
generally applicable.
c. Significant Energy Savings
    EPCA also mandates that DOE consider whether amended energy 
conservation standards for gas wall fan type vented heaters, gas wall 
gravity type vented heaters, and gas room vented heaters would result 
in result in significant conservation of energy. (42 U.S.C. 
6295(m)(1)(A) and 42 U.S.C. 6295(n)(2)(A)) As explained in section 
II.B.5 of this document, DOE uses a two-step approach that considers 
both a quad threshold value (0.3 quads of site energy over a 30-year 
period) and a percentage threshold value (10 percent reduction in 
energy usage over a 30-year period) to ascertain whether a potential 
standard satisfies 42 U.S.C. 6295(o)(3)(B), which requires DOE to avoid 
setting a standard that ``will not result in significant conservation 
of energy.'' As discussed in section III.B.3.e of this document, the 
technology options for vented heaters have not changed significantly 
since the April 2010 final rule and October 2016 final determination 
analyses were conducted. Therefore, DOE based its energy savings 
analysis on the estimates developed during the April 2010 final rule 
and October 2016 final determination. Based on its analysis, DOE 
estimated that for gas wall fan type vented heaters, gas wall gravity 
type vented heaters, and gas room vented heaters, potential site energy 
savings from more-stringent standards at the max-tech level would be 
0.13 quads, which is less than quad threshold value of 0.3 quads. As 
the quad threshold value was not met at max-tech, DOE next considered 
the percentage threshold. DOE again referred to the analysis conducted 
for the April 2010 final rule and estimated that the reduction in site 
energy use under an energy conservation standard at the max-tech level 
would be six percent, which is less than the percentage threshold of 10 
percent. As both the quad and percentage thresholds are not met, DOE 
has tentatively determined that amended standards would not result in 
significant conservation of energy. This tentative conclusion, if 
confirmed after review of public comments, would be sufficient on its 
own under EPCA to support a determination that the energy conservation 
standards for DHE do not need to be amended.
d. Further Considerations
    As previously discussed, DOE is required to publish either a 
notification of a determination that standards for vented heaters do 
not need to be amended, or a NOPR including new proposed standards. (42 
U.S.C. 6295(m)(1) and 42 U.S.C. 6295(m)(3)(B)) If DOE publishes a NOPR 
including new proposed standards, the proposed standards must be 
designed to achieve the maximum improvement in energy efficiency, which 
DOE determines is technologically feasible and economically justified. 
(42 U.S.C. 6295(m)(1)(B); 42 U.S.C. 6295(o)(2)(A)). In determining 
whether new proposed standards would be economically justified, DOE 
must determine whether the benefits of the standards exceed their 
burdens by, to the greatest extent practicable, considering, the seven

[[Page 77038]]

statutory criteria previously discussed. (42 U.S.C. 6295(o)(2)(B)(i))
    For gas wall fan type vented heaters, gas wall gravity type vented 
heaters, and gas room vented heaters, DOE considered the findings of 
the April 2010 final rule and the October 2016 final determination, in 
addition to comments received in response to the February 2019 RFI. As 
discussed in section III.B.3.g of this document, the number of vented 
heater shipments were projected to decline in the April 2010 final 
rule, and comments received during the rulemaking that resulted in the 
October 2016 final determination indicated that shipments have indeed 
continued to decline since the previous analysis was conducted. 
Further, DOE stated in the April 2016 NOPD which preceded the October 
2016 final determination that shipments were in fact lower than 
projected in the April 2010 final rule, indicating that the decline has 
been faster than expected. 81 FR 21276, 21281 (April 11, 2016). This 
supports the notion that the vented heater market is continuing to 
shrink, that product lines are mainly maintained as replacements for 
existing vented heaters units, and that new product lines generally are 
not being developed. In addition, the one new manufacturer of vented 
heaters that has entered the market since the October 2016 final 
determination only produces two models, neither of which have AFUE 
values outside of the range offered by other manufacturers, or any 
other characteristics that make them unique from other products already 
on the market. As discussed in sections III.B.3.a and III.B.3.d of this 
document, DOE found that the available AFUE values have largely stayed 
the same or decreased, with more-efficient products being taken off the 
market or rerated to lower AFUE values.
    As discussed in section III.B.3.f of this document, an examination 
of how the inputs to the LCC and PBP analysis have changed since the 
April 2010 final rule indicates that the LCC and PBP results from the 
April 2010 final rule would be comparable today. As discussed in 
section III.B.3.i of this document, DOE did not receive any comments or 
data in response to the February 2019 RFI that suggested a change in 
the historical trends within this industry.
    In the April 2010 final rule, DOE rejected higher standards, 
finding that capital conversion costs would lead to a large reduction 
in INPV and that small businesses would be disproportionately impacted, 
which would outweigh any benefits from higher standard levels. 75 FR 
20112, 20217-20218 (April 16, 2010). Upon reviewing the current market 
for vented heaters, DOE has tentatively determined that its prior 
determination regarding the impact on INPV remains valid (i.e., 
standard levels above the current Federal energy conservation standard 
would require manufacturers to make significant capital investments of 
the magnitude initially projected in the April 2010 final rule). As 
shipments for vented heaters have continued to decrease, manufacturers 
would be required to make investments to update model lines and 
manufacturing facilities with fewer shipments over which to spread the 
cost. This would lead to even more difficulty in recovering their 
investment than was projected in the April 2010 final rule.
    In addition, DOE has initially determined that its conclusions 
regarding small business impacts from the April 2010 final rule and the 
October 2016 final determination are still valid concerns (i.e., small 
businesses would be likely to reduce product offerings or leave the 
vented heater market entirely if the standard were to be set above the 
level adopted in that rulemaking). Four of the five identified 
manufacturers of gas wall fan type vented heaters, gas wall gravity 
type vented heaters, and gas room vented heaters are small businesses.
e. Standby Mode and Off Mode
    DOE also considered whether to establish energy conservation 
standards for standby mode and off mode electrical energy use. Fossil 
fuel energy use in standby mode and off mode is already included in the 
AFUE metric, so, therefore, separate standards for standby mode and off 
mode fossil fuel energy consumption are not needed. Given that the 
technologies in vented heaters are largely unchanged from those in the 
April 2010 final rule and October 2016 final determination, electric 
standby mode and off mode energy use is still very small in comparison 
to fossil fuel energy, and, thus, presents a relatively small potential 
for energy savings. DOE has tentatively determined that any energy 
savings from establishing energy conservation standards for standby 
mode and off mode electrical energy use, even when considered with 
active mode, would not increase the energy savings to a level above the 
quad or percentage threshold values established in the Process Rule and 
described in section II.B.5 of this document.
f. Summary
    For gas floor vented heaters, DOE tentatively concludes that more-
stringent standards for gas floor vented heaters are not 
technologically feasible. As such, DOE also tentatively concludes that 
there is no conservation of energy possible from including gas floor 
vented heaters. Therefore, DOE has tentatively determined that amended 
standards for gas floor vented heaters are not needed.
    For gas wall fan type vented heaters, gas wall gravity type vented 
heaters, and gas room vented heaters DOE has tentatively determined 
that amended standards would not result in significant conservation of 
energy. Further, the potential benefits from amended standards would be 
outweighed by burdens on manufacturers. As such, DOE has tentatively 
determined that new proposed standards would not be economically 
justified. Therefore, DOE has tentatively determined that amended 
standards for gas wall fan type vented heaters, gas wall gravity type 
heaters, and gas room vented heaters are not needed.

IV. Procedural Issues and Regulatory Review

A. Review Under Executive Order 12866

    The Office of Management and Budget (OMB) has determined that this 
proposed determination does not constitute a ``significant regulatory 
action'' under section 3(f) of E.O. 12866, ``Regulatory Planning and 
Review,'' 58 FR 51735 (Oct. 4, 1993). Accordingly, this action was not 
subject to review under the Executive Order by the Office of 
Information and Regulatory Affairs (OIRA) at OMB.

B. Review Under Executive Orders 13771 and 13777

    On January 30, 2017, the President issued E.O. 13771, ``Reducing 
Regulation and Controlling Regulatory Costs.'' 82 FR 9339 (Feb. 3, 
2017). E.O. 13771 stated the policy of the Executive Branch is to be 
prudent and financially responsible in the expenditure of funds, from 
both public and private sources. E.O. 13771 stated it is essential to 
manage the costs associated with the governmental imposition of private 
expenditures required to comply with Federal regulations. This 
notification of proposed determination is expected to be an E.O. 13771 
``Other Action.''
    Additionally, on February 24, 2017, the President issued E.O. 
13777, ``Enforcing the Regulatory Reform Agenda.'' 82 FR 12285 (March 
1, 2017). E.O. 13777 required the head of each agency to designate an 
agency official as its Regulatory Reform Officer (RRO). Each RRO 
oversees the implementation of regulatory reform initiatives and 
policies to ensure that agencies effectively carry out regulatory 
reforms,

[[Page 77039]]

consistent with applicable law. Further, E.O. 13777 requires the 
establishment of a regulatory task force at each agency. The regulatory 
task force is required to make recommendations to the agency head 
regarding the repeal, replacement, or modification of existing 
regulations, consistent with applicable law. At a minimum, each 
regulatory reform task force must attempt to identify regulations that:
    (1) Eliminate jobs, or inhibit job creation;
    (2) Are outdated, unnecessary, or ineffective;
    (3) Impose costs that exceed benefits;
    (4) Create a serious inconsistency or otherwise interfere with 
regulatory reform initiatives and policies;
    (5) Are inconsistent with the requirements of Information Quality 
Act, or the guidance issued pursuant to that Act, in particular those 
regulations that rely in whole or in part on data, information, or 
methods that are not publicly available or that are insufficiently 
transparent to meet the standard for reproducibility; or
    (6) Derive from or implement Executive Orders or other Presidential 
directives that have been subsequently rescinded or substantially 
modified.
    DOE initially concludes that this proposed determination is 
consistent with the directives set forth in these Executive Orders. As 
discussed in this document, DOE has initially determined that amended 
energy conservation standards for DHE products are not needed. 
Therefore, if finalized as proposed, this determination is expected to 
be an E.O. 13771 ``Other Action.''

C. 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 E.O. 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 (http://energy.gov/gc/office-general-counsel).
    DOE reviewed this proposed determination under the provisions of 
the Regulatory Flexibility Act and the policies and procedures 
published on February 19, 2003. Because DOE is proposing not to amend 
standards for DHE, if adopted, the determination would not amend any 
energy conservation standards. On the basis of the foregoing, DOE 
certifies that the proposed determination, if adopted, would not have a 
``significant economic impact on a substantial number of small 
entities.'' Accordingly, DOE has not prepared an IRFA for this proposed 
determination. DOE will transmit this 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).

D. Review Under the Paperwork Reduction Act

    This proposed determination, which proposes to determine that 
amended energy conservation standards for DHE would be unneeded as they 
would either be technologically infeasible (unvented heaters and gas 
floor vented heaters), or would not result in significant conservation 
of energy (gas wall fan type vented heaters, gas wall gravity type 
vented heaters, and gas room vented heaters), would impose no new 
informational or recordkeeping requirements. Accordingly, OMB clearance 
is not required under the Paperwork Reduction Act. (44 U.S.C. 3501 et 
seq.)

E. Review Under the National Environmental Policy Act of 1969

    DOE is analyzing this proposed action in accordance with the 
National Environmental Policy Act of 1969 (NEPA) and DOE's NEPA 
implementing regulations (10 CFR part 1021). DOE's regulations include 
a categorical exclusion for actions which are interpretations or 
rulings with respect to existing regulations. 10 CFR part 1021, subpart 
D, Appendix A4. DOE anticipates that this action qualifies for 
categorical exclusion A4 because it is an interpretation or ruling in 
regards to an existing regulation and otherwise meets the requirements 
for application of a categorical exclusion. See 10 CFR 1021.410. DOE 
will complete its NEPA review before issuing the final action.

F. Review Under Executive Order 13132

    E.O. 13132, ``Federalism,'' 64 FR 43255 (August 10, 1999), imposes 
certain requirements on Federal 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 determination 
and has tentatively 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 
determination. 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) As this proposed determination would not amend the 
standards for DHE, there is no impact on the policymaking discretion of 
the States. Therefore, no action is required by E.O. 13132.

G. Review Under Executive Order 12988

    Regarding the review of existing regulations and the promulgation 
of new regulations, section 3(a) of E.O. 12988, ``Civil Justice 
Reform,'' 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. 61 FR 4729 (Feb. 7, 1996). 
Regarding the review required by section 3(a), section 3(b) of E.O. 
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

[[Page 77040]]

draftsmanship under any guidelines issued by the Attorney General. 
Section 3(c) of E.O. 12988 requires Executive agencies to review 
regulations in light of applicable standards in section 3(a) and 
section 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, this proposed 
determination meets the relevant standards of E.O. 12988.

H. 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 them. On March 18, 1997, DOE published 
a statement of policy on its process for intergovernmental consultation 
under UMRA. 62 FR 12820. DOE's policy statement is also available at: 
http://energy.gov/sites/prod/files/gcprod/documents/umra_97.pdf.
    DOE examined this proposed determination according to UMRA and its 
statement of policy and determined that the proposed determination does 
not contain a Federal intergovernmental mandate, nor is it expected to 
require expenditures of $100 million or more in any one year. As a 
result, the analytical requirements of UMRA do not apply.

I. 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 determination 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.

J. Review Under Executive Order 12630

    Pursuant to E.O. 12630, ``Governmental Actions and Interference 
with Constitutionally Protected Property Rights,'' 53 FR 8859 (March 
18, 1988), DOE has determined that this proposed determination would 
not result in any takings that might require compensation under the 
Fifth Amendment to the U.S. Constitution.

K. Review Under the 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 Federal agencies to review 
most disseminations of information to the public under information 
quality 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). DOE has reviewed this NOPD under the OMB and DOE 
guidelines and has concluded that it is consistent with applicable 
policies in those guidelines.

L. Review Under Executive Order 13211

    E.O. 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 OIRA at 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 promulgates or is expected to lead to promulgation of a 
final rule, and that: (1) Is a significant regulatory action under E.O. 
12866, or any successor Executive 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.
    This proposed determination, which does not propose to amend the 
energy conservation standards for DHE, is not a significant regulatory 
action under E.O. 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 
at OIRA. Therefore, it is not a significant energy action, and 
accordingly, DOE has not prepared a Statement of Energy Effects.

M. Review Under the Information Quality Bulletin for Peer Review

    On December 16, 2004, OMB, in consultation with the Office of 
Science and Technology Policy (OSTP), issued its Final Information 
Quality Bulletin for Peer Review (the Bulletin). 70 FR 2664 (Jan. 14, 
2005). The Bulletin establishes that certain scientific information 
shall be peer reviewed by qualified specialists before it is 
disseminated by the Federal Government, including influential 
scientific information related to agency regulatory actions. The 
purpose of the bulletin is to enhance the quality and credibility of 
the Government's scientific information. Under the Bulletin, the energy 
conservation standards rulemaking analyses are ``influential scientific 
information,'' which the Bulletin defines as ``scientific information 
the agency reasonably can determine will have, or does have, a clear 
and substantial impact on important public policies or private sector 
decisions.'' Id. at 70 FR 2667.
    In response to OMB's Bulletin, DOE conducted formal peer reviews of 
the energy conservation standards development process and the analyses 
that are typically used and has prepared a Peer Review report 
pertaining to the energy conservation standards rulemaking 
analyses.\25\ Generation of this report involved a rigorous, formal, 
and documented evaluation using objective criteria and qualified and 
independent reviewers to make a judgment as to the technical/
scientific/business merit, the actual or anticipated results, and the 
productivity and management effectiveness of programs and/or projects. 
DOE has determined that the peer-reviewed analytical process continues 
to reflect current practice, and the Department followed that process 
for considering amended

D. Submission of Comments

    DOE will accept comments, data, and information regarding this 
proposed determination no later than the date provided in the DATES 
section at the beginning of this proposed determination. Interested 
parties may submit comments, data, and other information using any of 
the methods described in the ADDRESSES section at the beginning of this 
document.
    Submitting comments via http://www.regulations.gov. The http://www.regulations.gov web page will require you to provide your name and 
contact information. Your contact information will be viewable to DOE 
Building Technologies staff only. Your contact information will not be 
publicly viewable except for your first and last names, organization 
name (if any), and submitter representative name (if any). If your 
comment is not processed properly because of technical difficulties, 
DOE will use this information to contact you. If DOE cannot read your 
comment due to technical difficulties and cannot contact you for 
clarification, DOE may not be able to consider your comment.
    However, your contact information will be publicly viewable if you 
include it in the comment itself or in any documents attached to your 
comment. Any information that you do not want to be publicly viewable 
should not be included in your comment, nor in any document attached to 
your comment. Otherwise, persons viewing comments will see only first 
and last names, organization names, correspondence containing comments, 
and any documents submitted with the comments.
    Do not submit to http://www.regulations.gov information for which 
disclosure is restricted by statute, such as trade secrets and 
commercial or financial information (hereinafter referred to as 
Confidential Business Information (CBI)). Comments submitted through 
http://www.regulations.gov cannot be claimed as CBI. Comments received 
through the website will waive any CBI claims for the information 
submitted. For information on submitting CBI, see the Confidential 
Business Information section.
    DOE processes submissions made through http://www.regulations.gov 
before posting. Normally, comments will be posted within a few days of 
being submitted. However, if large volumes of comments are being 
processed simultaneously, your comment may not be viewable for up to 
several weeks. Please keep the comment tracking number that http://www.regulations.gov provides after you have successfully uploaded your 
comment.
    Submitting comments via email, hand delivery/courier, or postal 
mail. Comments and documents submitted via email, hand delivery/
courier, or postal mail also will be posted to http://www.regulations.gov. If you do not want your personal contact 
information to be publicly viewable, do not include it in your comment 
or any accompanying documents. Instead, provide your contact 
information in a cover letter. Include your first and last names, email 
address, telephone number, and optional mailing address. With this 
instruction followed, the cover letter will not be publicly viewable as 
long as it does not include any comments.
    Include contact information each time you submit comments, data, 
documents, and other information to DOE. If you submit via postal mail 
or hand delivery/courier, please provide all items on a CD, if 
feasible, in which case it is not necessary to submit printed copies. 
No telefacsimiles (faxes) will be accepted.
    Comments, data, and other information submitted to DOE 
electronically should be provided in PDF (preferred), Microsoft Word or 
Excel, WordPerfect, or text (ASCII) file format. Provide documents that 
are not secured, that are written in English, and that are free of any 
defects or viruses. Documents should not contain special characters or 
any form of encryption and, if possible, they should carry the 
electronic signature of the author.
    Campaign form letters. Please submit campaign form letters by the 
originating organization in batches of between 50 to 500 form letters 
per PDF or as one form letter with a list of supporters' names compiled 
into one or more PDFs. This reduces comment processing and posting 
time.
    Confidential Business Information. Pursuant to 10 CFR 1004.11, any 
person submitting information that he or she believes to be 
confidential and exempt by law from public disclosure should submit via 
email, postal mail, or hand delivery/courier two well-marked copies: 
One copy of the document marked ``confidential'' including all the

[[Page 77042]]

information believed to be confidential, and one copy of the document 
marked ``non-confidential'' with the information believed to be 
confidential deleted. Submit these documents via email or on a CD, if 
feasible. DOE will make its own determination about the confidential 
status of the information and treat it according to its determination.
    It is DOE's policy that all comments may be included in the public 
docket, without change and as received, including any personal 
information provided in the comments (except information deemed to be 
exempt from public disclosure).
