Gas Products as a Covered Consumer Product

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

ACTION: Final rule; final determination.

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

SUMMARY: The U.S. Department of Energy (``DOE'') has determined that 
miscellaneous gas products (``MGPs''), which are comprised of 
decorative hearths and outdoor heaters, qualify as covered products

I. Introduction

    The following section briefly discusses the statutory authority 
underlying this final rule, as well as some of the relevant historical 
background related to the inclusion of MGPs as covered equipment under 
the Energy Policy and Conservation Act (``EPCA''), as amended.

A. Statutory Authority

    EPCA \1\ authorizes DOE to regulate the energy efficiency of a 
number of consumer products and certain industrial equipment. Title 
III, Part B \2\ 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 for certain consumer 
products, referred to generally as ``covered products''.\3\ In addition 
to specifying a list of consumer products that are covered products, 
EPCA authorizes the Secretary of Energy to classify additional types of 
consumer products as covered products. EPCA defines a ``consumer 
product'' in relevant part as any article (other than an automobile) of 
a type--(A) which in operation consumes, or is designed to consume, 
energy; and (B) which, to any significant extent, is distributed in 
commerce for personal use or consumption by individuals; without regard 
to whether such article of such type is in fact distributed in commerce 
for personal use or consumption by an individual.\4\ (42 U.S.C. 
6291(a)(1)) For a given consumer product to be classified as a covered 
product, the Secretary must determine that: classifying the product as 
a covered product is necessary or appropriate to carry out the purposes 
of this chapter; and the average annual per-household energy use by 
products of such type is likely to exceed 100 kilowatt-hours (``kWh'') 
(or its British thermal unit (``Btu'') equivalent) per year. (42 U.S.C. 
6292(b)(1)) \5\
---------------------------------------------------------------------------

    \1\ All references to EPCA in this document refer to the statute 
as amended through the Energy Act of 2020, Public Law 116-260 (Dec. 
27, 2020).
    \2\ For editorial reasons, upon codification in the U.S. Code, 
Part B was redesignated Part A and is hereinafter referred to as 
such.
    \3\ The enumerated list of covered products is at 42 U.S.C. 
6292(a)(1)-(19).
    \4\ As such, in considering the potential scope of coverage, DOE 
does not consider whether an individual product is distributed in 
commerce for residential or commercial use, but whether it is of a 
type of product distributed in commerce for residential use.
    \5\ DOE has defined ``household'' to mean an entity consisting 
of either an individual, a family, or a group of unrelated 
individuals, who reside in a particular housing unit. For the 
purpose of this definition:
    Group quarters means living quarters that are occupied by an 
institutional group of 10 or more unrelated persons, such as a 
nursing home, military barracks, halfway house, college dormitory, 
fraternity or sorority house, convent, shelter, jail or correctional 
institution.
    Housing unit means a house, an apartment, a group of rooms, or a 
single room occupied as separate living quarters, but does not 
include group quarters.
    Separate living quarters means living quarters: (i) to which the 
occupants have access either directly from outside of the building, 
or through a common hall that is accessible to other living quarters 
and that does not go through someone else's living quarters, and 
(ii) occupied by one or more persons who live and eat separately 
from occupant(s) of other living quarters, if any, in the same 
building. 10 CFR 430.2.
---------------------------------------------------------------------------

    When attempting to cover additional consumer product types, DOE 
must first determine whether these criteria from 42 U.S.C. 6292(b)(1) 
are met. Once a determination is made, the Secretary may prescribe test 
procedures to measure the energy efficiency or energy use of such 
product. (42 U.S.C. 6293(a)(1)(B)) Furthermore, once a product is 
determined to be a covered product, the Secretary may set standards for 
such product, subject to the provisions in 42 U.S.C. 6295(o) and (p), 
provided that DOE determines that four additional criteria at 42 U.S.C. 
6295(l) have been met. Specifically, 42 U.S.C. 6295(l) requires the 
Secretary to determine that: the average household energy use of the 
products has exceeded 150 kWh per household for a 12-month period; the 
aggregate 12-month energy use of the products has exceeded 4,200 
gigawatthours; substantial improvement in energy efficiency of products 
of such type is technologically feasible; and application of a labeling 
rule under 42 U.S.C. 6294 is unlikely to be sufficient to induce 
manufacturers to produce, and consumers and other persons to purchase, 
covered products of such type (or class) that achieve the maximum 
energy efficiency that is technologically feasible and economically 
justified. (42 U.S.C. 6295(l)(1))

B. Background

    On February 7, 2022, DOE published a notice of proposed 
determination (``NOPD'') that proposed to determine coverage for MGPs, 
which are consumer products comprising: (1) Those hearth products that 
are not direct heating equipment (``DHE'') (i.e., those hearth products 
that are indoor or outdoor decorative hearth products) and (2) outdoor 
heaters. 87 FR 6786 (``February 2022 NOPD''). The rulemaking history of 
MGPs as well as hearth products is discussed in the February 2022 NOPD. 
87 FR 6786, 6787--6788.

II. General Discussion

    DOE developed this determination after considering comments, data, 
and information from interested parties that represent a variety of 
interests. Table II.1 lists the interested parties that provided 
comments on the February 2022 NOPD.

A. Definitions and Scope of Coverage

    MGPs as considered in this final determination are comprised of 
decorative hearth products and outdoor heaters. In the February 2022 
NOPD, DOE proposed to define a ``decorative hearth product'' as a gas-
fired appliance that:
     Simulates a solid-fueled fireplace or presents a flame 
pattern;
     Includes products designed for indoor use, outdoor use, or 
either indoor or outdoor use;
     Is not designed to be operated with a thermostat;
     For products designed for indoor use, is not designed to 
provide space heating to the space in which it is installed; and
     For products designed for outdoor use, is not designed to 
provide heat proximate to the unit. 87 FR 6786, 6790. A wide range of 
decorative hearth products are available on the market, including, for 
example, gas log sets, gas fire pits, gas stoves, and gas fireplace 
inserts. Decorative hearth products may be used indoors or outdoors.
    In the February 2022 NOPD, DOE proposed to define an ``outdoor 
heater'' as a gas-fired appliance designed for use in outdoor spaces 
only, and which is designed to provide heat proximate to the unit. 87 
FR 6786, 6790.
1. Outdoor Heaters
    In response to the definition for outdoor heaters proposed in the 
February 2022 NOPD, HHT commented that the proposed definition for 
outdoor heaters is very broad as it covers radiant heaters, firepits, 
and outdoor fireplaces. HHT added that the majority of the products in 
this category are for aesthetic appeal and not for use as a local heat 
source. (HHT, No. 9 at p. 2)
    HPBA commented that the definition of outdoor heaters is vague, 
overbroad, unjustified, and susceptible to potential abuse. HPBA stated 
that if DOE intends to cover products other than gas-fired outdoor 
infrared patio heaters subject to the [American National Standards 
Institute (ANSI)] Z83.26 standard, they must be identified and a 
justification for their coverage provided. (HPBA, No. 11 at pp. 47-48) 
HPBA added that the definition is overbroad because it includes 
portable and non-portable units subject to ANSI Z83.26. HPBA stated 
that these two categories of products are too different in their design 
and constraints to be considered a single product. HPBA suggested that 
a heating efficiency standard for any of these products should be 
limited to strictly utilitarian heating products and should exclude 
``patio heaters.'' Further, HPBA stated that patio heaters are not 
strictly utilitarian as they provide outdoor lighting or visual appeal 
and are likely to be compromised by high heating efficiencies. (Id. at 
p. 48)
    Moroz commented that patio heaters are the only outdoor appliance 
that should be covered as outdoor heaters, and stated that gas 
fireplaces and gas fire pits serve as decorative appliances, and should 
not be considered outdoor heaters. Moroz commented that they are only 
aware of outdoor gas fireplaces for decorative use, as opposed to being 
intended as heaters. Moroz questioned the benefit of regulating the 
efficiency of an appliance that emits heat directly to the atmosphere. 
(Moroz, No. 7 at p. 1)
    The definition of outdoor heaters, as DOE proposed to define it in 
the February 2022 NOPD and as adopted in this final determination, 
could include products such as patio heaters, outdoor fire pits, and 
outdoor fireplaces, so long as they are designed to provide heat to the 
space around the unit. (DOE notes that were such products not designed 
to provide heat to the space proximate the unit, they may instead be 
classified as decorative hearth products.) Therefore, DOE clarifies 
that products other than patio heaters could meet the definition of 
outdoor heaters, if those products are designed for use in outdoor 
spaces and designed to provide heat to the space proximate the unit. In 
contrast to the assertions by commenters that the definition is 
overbroad, DOE notes that products must meet specific criteria to be 
considered an outdoor heater--be designed for installation in outdoor 
spaces only, and be designed to provide heat proximate to the unit. If 
a product does not meet both aspects of this definition it would not be 
an ``outdoor heater''. Regardless of whether a product is marketed as a 
``patio heater'' or some other term, or if it is certified to ANSI 
Z83.26 or another standard, it would be covered as an ``outdoor 
heater'' if it meets both parts of this definition. A product that is 
designed for installation outdoors, but that is not designed to provide 
heat proximate to the unit may be classified as a decorative hearth 
product if all other definitional criteria for decorative hearth 
product were met.
    Moroz commented that an outdoor heater is operated when outdoor 
temperatures cause personal discomfort, and a decorative hearth 
appliance is operated when the user wishes to enjoy the ambiance 
created by the flame of the appliance. (Moroz, No. 7 at p. 2) HPBA 
suggested that patio heaters may produce a combination of heat, 
lighting, and/or visual appeal. (HPBA, No. 11 at p. 53) As noted above, 
outdoor products may be outdoor heaters or decorative hearth products, 
depending on whether

[[Page 54333]]

they are designed to provide heat proximate to the unit.
    AHRI commented that manufacturers of fixed installation infrared 
outdoor heating equipment may approve their products to ANSI Z83.19, 
ANSI Z83.20, and ANSI Z83.26. AHRI further stated that heaters 
certified to these standards should be excluded from the definition of 
``outdoor heaters''. They commented that these standards set minimum 
radiant energy requirements and that, pursuant to 42 U.S.C. 6295(l), 
DOE would be required to demonstrate that a substantial improvement in 
energy efficiency is technologically feasible for such products. (AHRI, 
No. 16 at pp. 1-2) AHRI commented that the ANSI Z83.19 standard, Gas-
Fired High-Intensity Infrared Heaters, is limited in its application to 
indoor non-residential and outdoor use and sets a minimum requirement 
for the radiant coefficient, which must be measured. (Id.) AHRI also 
stated that a fixed installation product that has been tested and 
certified to meet ANSI Z83.19 may in some instances choose to include 
additional certification to ANSI Z83.26, but that ANSI Z83.26 is not 
applicable to fixed installation heaters. (Id.) AHRI stated that the 
majority of heaters approved to ANSI Z83.19 are for industrial and 
commercial indoor use only although it may include coverage for outdoor 
use. AHRI commented that fixed installation outdoor heaters should be 
excluded from the proposed coverage determination because they are 
primarily certified to ANSI Z83.19 and ANSI Z83.20, which have 
provisions for minimum radiant energy measurement. (Id.) Moreover, AHRI 
commented that any heater primarily certified to ANSI Z83.19 and Z83.20 
with additional certification to Z83.26 should be excluded from the 
scope of this rulemaking. (Id.)
    AHRI commented that DOE should use industry consensus definitions 
for these products from appropriate industry standards to avoid 
products falling in and out of multiple classifications. (Id.) 
Additionally, AHRI commented that the definition of outdoor heaters 
should specify that their primary purpose is providing proximate heat 
and that such units are not an otherwise covered product. AHRI stated 
that without this specification, DOE may risk including otherwise 
unrelated covered products into the scope of its determination. (Id.)
    The definition of ``outdoor heater'' proposed in the February 2022 
NOPD and adopted in this final determination specifies that these 
products are ``designed to provide heat proximate to the unit.'' DOE 
notes that pursuant to 42 U.S.C. 6295(l), as discussed in section I.A, 
DOE is required to determine substantial improvement in energy 
efficiency is technologically feasible for any type (or class) of 
covered products. This coverage determination defines ``miscellaneous 
gas products'' as a covered product, which includes outdoor heaters, 
but DOE is not analyzing potential energy conservation standards in 
this notice. DOE will consider the technical feasibility, energy 
savings, and economic justification of potential energy conservation 
standards in a separate standards rulemaking. Furthermore, the 
requirement in EPCA that substantial energy efficiency improvement is 
technologically feasible is determined with respect to MGPs as a whole, 
including all products that would meet the definitions of outdoor 
heaters and decorative hearth products.
    DOE acknowledges that the ANSI Z83.19 \6\ and ANSI Z83.20 \7\ 
standards cover heaters ``intended for installation in and heating 
outdoor spaces or nonresidential indoor spaces''. However, as discussed 
in section II.A.3, the definition of ``consumer product'' as defined in 
42 U.S.C. 6291(1) does not exclude coverage based on use in commercial 
applications as long as a product is, ``to any significant extent, 
distributed in commerce for personal use or consumption by 
individuals''. Therefore, products that are distributed to a 
significant extent for residential use are appropriately classified as 
consumer products under EPCA. Additionally, 42 U.S.C. 6311(2)(A)(iii) 
specifies that the term ``industrial equipment'' excludes a product 
which is a ``covered product'' as defined in section 6291(a)(2)''. 
Thus, outdoor heaters meeting the definition established under this 
rule will not be subject to both the consumer product and industrial 
equipment provisions of EPCA. Additionally, 42 U.S.C 6295(l) specifies 
the criteria that DOE must satisfy in order to set standards for 
consumer products that the Secretary classifies as covered products, 
and whether or not such products are subject to industry standards or 
efficiency metrics is not a listed criterion.

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

2. Decorative Hearth Products
    In response to the definition for ``decorative hearth product'' 
initially proposed in the February 2022 NOPD (see section II.A of this 
document), Moroz commented that ``decorative hearth products'' is too 
broad of a term and that the definitions found in the Canadian 
Regulation for Gas Fireplaces \8\ are more specific and appropriate, 
and that DOE should align with the Canadian regulations where 
applicable. (Moroz, No. 7 at p. 1) OGC commented that ``decorative 
hearth products'' is too broad of a term to use for both indoor and 
outdoor decorative products that must comply with very different 
industry standards. OGC also commented that the primary function of 
outdoor decorative hearth products is the aesthetic qualities of their 
flame, and not the production of heat. OGC also commented that 
``outdoor hearth products,'' as a category of products, was not defined 
in the scope of coverage in the February 2022 NOPD. (OGC, No. 8 at pp. 
1-2) HHT commented that the primary function of the majority of hearth 
products is to have aesthetically appealing flames, as opposed to 
heating. (HHT, No. 9 at p. 2) Similarly, HPBA stated that fireplaces 
and similar products inherently produce heat and are designed ``to be 
suitable for utilitarian use,'' but they nevertheless state that these 
products cannot be reasonably regulated as utilitarian heating 
products. HPBA commented that it is an invalid assumption that products 
that produce heat are ``heaters'' and would be improved by a higher 
heating efficiency. HPBA also stated that gas fireplaces or similar 
products are not ``purely decorative'' because it is incorrect to 
assume that these products are not intended to provide heat. (HPBA, No. 
11 at pp. 46-47)
---------------------------------------------------------------------------

    \8\ Natural Resources Canada (NRCan) defines a ``gas fireplace'' 
as a decorative gas fireplace or a heating gas fireplace. Further, a 
``decorative gas fireplace means a vented fireplace that is fuelled 
by natural gas or propane, is marked for decorative use only and is 
not equipped with a thermostat or intended for use as a heater'' and 
a ``heating gas fireplace means a vented fireplace that is fuelled 
by natural gas or propane and is not a decorative gas fireplace.'' 
See www.nrcan.gc.ca/energy-efficiency/energy-efficiency-regulations/guide-canadas-energy-efficiency-regulations/gas-fireplaces/6865.
---------------------------------------------------------------------------

    As noted in the February 2022 NOPD, a variety of products, such as 
gas log sets, gas fire pits, gas stoves, and gas fireplace inserts 
(among others) could be considered as decorative hearth products if 
they meet all the definitional criteria. 87 FR 6786, 6788. DOE further

[[Page 54334]]

notes that the decorative hearth products, as defined, can be marketed 
for use both indoors and outdoors. However, DOE may consider the 
relevant differences in indoor and outdoor products in any future 
analysis of potential test procedures and energy conservation standards 
for these products.
    In response to comments stating that the function of hearth 
products can include aesthetics as well as heating, DOE notes that 
under its definition, decorative hearth products are not designed to 
provide heating to the space in which they are installed (indoor units) 
or the space proximate the heater (outdoor units). Although decorative 
hearths may give off some heat as a byproduct of the flame, the 
aesthetic appeal is what the product is designed to be used for, rather 
than the heating function.
    HPBA commented that vented gas log sets are set apart from vented 
gas fireplaces by their unmatched realism and design for installation 
directly into the hearth of existing wood-burning fireplaces. HPBA 
stated that manufacturers work to minimize the visibility of hardware 
components to maximize realism in these products. HPBA added that 
electronic ignition systems require significant additional hardware, 
some of which is heat-sensitive, and compromise the visual appeal of 
the product. (HPBA, No. 11 at p. 40) HPBA stated that while gas log 
sets are the most ``decorative'' of all indoor products and may have 
little net heating utility in a normally heated home, they provide 
emergency heating utility when central heating systems are out. HPBA 
commented that continuous pilot lights, unlike electric ignition, are 
able to operate in an electrical outage. Further, HPBA stated that 
battery backup systems require much more vigilance with respect to 
battery replacement and that they require heat-sensitive hardware which 
may make them less suitable for emergency situations. (Id. at p. 41) 
HPBA commented that during weather disasters, batteries are often in 
short supply and a gas log set with a continuous pilot light could be 
useful. HPBA commented that a continuous pilot ban for vented gas log 
sets would impose regulatory burdens on products for which there are no 
regulatory benefits. (Id. at p. 42) HPBA commented that vented gas log 
sets certified to the ANSI Z21.84 standard operate by direct main 
burner ignition, by definition, cannot have continuous pilot lights. 
HPBA stated that these products should not be subject to regulation 
because they do not have continuous pilot lights. (Id.)
    HPBA also commented that the volume of the flame is important for 
the fireplace installation to ``look right'' and that this feature is 
proportional to British thermal units (``Btu'') input. Therefore, HPBA 
states, important visual considerations effectively define a range of 
Btu inputs for a given installation. HPBA commented that heat output 
should not classify whether a product is a ``heater'' or ``purely 
decorative'' because flame art can have high heat outputs but should 
not be confused with utilitarian heating appliances. (HPBA, No. 11 at 
p. 51)
    DOE notes that the definition for decorative hearth product does 
not prescribe a limit on Btu input for fireplaces to distinguish 
products that are a ``heater'' from those that are ``purely 
decorative.'' When classifying products, the intended design of the 
product is the criteria used for categorization, allowing fireplaces 
with high Btu input rates to continue to be classified as a decorative 
hearth product if all other definitional elements are met.
    In the February 2022 NOPD, DOE tentatively determined that the 
presence of a thermostat indicates that a product is designed to 
provide heat rather than being purely decorative. Thus, the proposed 
definition of decorative hearth products excluded those products 
equipped with a thermostat. This determination was consistent with the 
relevant ANSI standard for decorative gas fireplaces (i.e., ANSI 
Z21.50, ``Vented Decorative Gas Appliances''), which excludes products 
that are equipped with a thermostat. DOE requested comment on whether 
the presence of a thermostat would indicate that a hearth product is 
intended to provide heat to the space in which it is installed rather 
than being purely decorative. 87 FR 6786, 6790.
    In response to the February 2022 NOPD, Moroz commented that it is 
inappropriate to assume that the presence of a thermostat always 
indicates that a hearth product is intended to provide heat to the 
space in which it is installed. Moroz commented that thermostats can 
provide automatic control of heat balance within the home, and in some 
cases act as a safety device. Moroz stated that while not currently 
applicable in the National Fire Protection Association (NFPA) 54, 
[``National Fuel Gas Code''], which the commenter suggests is the 
American installation code for gas appliances, CSA B149[.1] [``Natural 
Gas and Propane Installation Code''], which the commenter suggests is 
the Canadian installation code for gas appliances, requires that a 
thermostat be installed on a gas fireplace when used in a bedroom in 
order to intervene when a user is not conscious of the appliance's 
operation. (Moroz, No. 7 at p. 1)
    Similarly, HHT commented that thermostat allowance and usage is 
determined by the standard a unit is certified to. HHT added that 
thermostats are a device for comfort control and does not mean that 
those products are meant for use as a primary heating source. (HHT, No. 
9 at p. 1) OGC also commented that the use of a thermostat on a product 
is covered by the industry standard that the product is listed to. 
(OGC, No. 8 at p. 1) NPGA commented that a thermostat feature may be 
provided by manufacturers to assist consumers in measuring the 
intensity of the product but without the intention for consumers to 
utilize the product as a direct heating or space heating appliance. 
NPGA recommended that DOE consider defining decorative heath products 
by the purpose(s) and feature(s) present in the product instead of by 
the absence of a feature, or by disqualifying products according to the 
presence of a feature. (NPGA, No. 14 at p. 3)
    HPBA commented that thermostats on fireplaces and similar products 
can be used to turn a product on and off in response to heating demands 
or simply to prevent unintended overheating from non-utilitarian use. 
HPBA added that thermostats are not permitted on products certified to 
the ANSI Z21.50 standard but the presence of a thermostat does not 
indicate that such products are ``heaters'' or that they would be 
improved by a higher heating efficiency. (HPBA, No. 11 at p. 47)
    DOE appreciates this feedback regarding the presence of a 
thermostat as an indicator that a hearth product is intended to provide 
heat to the surrounding space. DOE notes that the ANSI Z21.50 for 
vented gas decorative appliances specifies that the appliances are not 
for use with a thermostat. Additionally, in its energy efficiency 
regulations, NRCan defines ``decorative gas fireplace'' as a vented 
fireplace that is fueled by natural gas or propane, is marked for 
decorative use only and is not equipped with a thermostat or intended 
for use as a heater.\9\ In an effort to align with industry standards 
and Canadian regulations, DOE concludes that it is appropriate to use 
the absence of a thermostat as a criterion for decorative hearth 
products. However, to fully align with ANSI Z21.50, DOE is

[[Page 54335]]

adopting a slight modification to criteria (3) in the definition of 
``decorative hearth products'' to read ``is not for use with a 
thermostat.'' \10\ DOE reasons that this slight modification, while not 
changing the intent of the definition proposed in the February 2022 
NOPD, will fully align with the language of the industry standard and 
further clarify the meaning of the definition to exclude from 
decorative hearth products those products that are used with a 
thermostat.

87 FR 6786, 6790.
---------------------------------------------------------------------------

    HPBA commented that outdoor gas log sets differ from vented gas log 
sets because they include ``match-lit'' products (which are not used 
indoors due to safety concerns), they are operable under the variable 
conditions encountered outdoors, and they do not necessarily need to be 
installed in existing fireplaces with functioning flue systems. (HPBA, 
No. 11 at pp. 43-44) DOE appreciates this feedback regarding vented gas 
log sets and the distinction from outdoor gas log sets. However, as 
discussed previously, these products are covered as decorative hearth 
products if they meet the criteria outlined in the definition. DOE may 
consider the differences in these products in any future analysis of 
potential test procedures and/or energy conservation standards for 
MGPs.
3. Miscellaneous Gas Products Scope
    In response to the February 2022 NOPD, HHT stated that the scope of 
coverage for MGPs is too broad and combines products that are used for 
aesthetic or decorative purposes with products used for heating. (HHT, 
No. 9 at p. 2)
    Similarly, Moroz commented that ``miscellaneous gas products'' is 
too vague of a title and should not include decorative hearth products, 
outdoor gas fireplaces, and outdoor heaters all within the same 
classification, but rather coverage of products should be more 
specific. (Moroz, No. 7 at pp. 2-3) OGC similarly commented that 
``miscellaneous gas products'' is too broad and mixes products that are 
primarily aesthetic and provide some comfort and illumination with 
products whose only utility is to provide heat. OGC suggested that DOE 
is attempting to cover any gas burning product with a visible flame 
regardless of its intended purpose. (OGC, No. 8 at p. 2)
    HPBA stated that neither ``outdoor heaters'' nor ``decorative 
hearth products'' are identifiable products; rather, HPBA stated they 
are a mishmash of products with little resemblance to one another. HPBA 
suggested that Congress did not intend for DOE to classify new products 
in this amorphous manner. (HPBA, No. 11 at pp. 22-23) Additionally, 
HPBA stated that DOE should abandon its definition-based approach to 
coverage determinations and instead use clear and precise details when 
describing a product. (HPBA, No. 11 at pp. 17-18) HPBA suggested that a 
descriptor similar to ``vented gas products certified to the ANSI 
Z21.88 standard'' would provide appropriate clarity and precision. (Id. 
at pp. 17-18) HPBA also stated that DOE cannot avoid the need for a 
coverage determination by ``interpreting'' a category of currently 
regulated products to include previously unregulated products, nor can 
it justify coverage for one product and assert coverage over another. 
(Id. at pp. 15-16) HPBA also stated that issuing a coverage 
determination requires product-specific consideration of issues to 
avoid products not reasonably susceptible to EPCA regulation from being 
swept into coverage along with other products and the gas usage of 
different products could be combined to meet EPCA's requirements at 42 
U.S.C. 6262(b)(1)(B). (Id. at p. 18)
    NPGA expressed agreement with the comment submitted by HPBA that a 
more specific definition of the products potentially subject to the 
rulemaking and of the efficiency objectives would benefit the current 
rulemaking. (NPGA, No. 6 at pp. 1-2) NPGA discouraged DOE from 
including decorative hearth products and outdoor heaters in the same 
category of MGPs because their primary function and features differ, 
even though there may be some overlap in their function. NPGA expressed 
concern for such wide encompassing definitions of MGPs because it may 
make some products immediately unable to meet a potential standard 
based solely on design limitations. (Id. at p. 2) NPGA commented that 
the DOE's rationale is difficult to understand and identify the value 
to be achieved by combining product types with different functionality 
and design. NPGA further added that, while the notice acknowledges that 
outdoor heaters and decorative products are different, an explanation 
for combining them is not offered. (Id. at p. 2) NPGA requested that 
the DOE separate decorative hearth products and outdoor heaters, and 
provide a narrower definition of the product types such as the 
differences between an outdoor fire table and an outdoor heater which 
may have different operating capacities and operating hours. (Id. at p. 
4) NGPA suggested that DOE should remove outdoor heaters from the 
definition of MGPs. (Id. at p. 2)
    AHRI opposed the inclusion of decorative hearths and outdoor 
heaters in the same rulemaking. (AHRI, No. 16 at p. 3) AHRI commented 
that if DOE includes these products under the scope of coverage, it 
should perform separate rulemakings for decorative products covered by 
ANSI Z21.50, Z21.60, Z21.84, and Z21.97, and for outdoor heaters 
covered by ANSI Z83.26 to provide better clarity on regulations and 
simplify test procedures and performance criteria. (Id. at p. 5) AHRI 
added that outdoor heaters and decorative hearths have fundamentally 
different utility under the proposed definitions for which, they 
stated, one must provide heating and the other cannot provide heating, 
as well as differences in terms of market distribution and aggregate 
national energy use. (Id. at pp. 2-3)
    The CA IOUs recommended that DOE should carefully develop 
complementary definitions for ``decorative hearth products'' and 
``vented hearth heaters'' to ensure appropriate coverage of products 
currently on the market. (CA IOUs, No.12 at p. 2) The CA IOUs commented 
that the shared appearance and performance characteristics of the 
various MGPs is highlighted by industry testimony (specifically, a 
comment submitted by HPBA) during the California Energy Commission's 
Title 20 rulemaking process that indicated that performance standards 
for vented hearth heaters could result in the reclassification of a 
``vast majority'' of heating products as decorative hearth products. 
The CA IOUs suggested that the ability to recertify products under 
different test procedures reinforces the need for complementary product 
definitions that provide appropriate coverage for all hearth products. 
(Id.)
    In addition, AHRI stated that MGPs would combine multiple product 
types across both residential and commercial applications and that it 
is unclear if the coverage of outdoor heaters is aimed at commercial or 
residential products. AHRI stated that it is unclear why ``commercial 
heating equipment'' would be included in a standard for residential 
decorative hearths. (AHRI, No. 16 at pp. 2-3) They also stated, it 
appears as though the only motivation to group decorative hearths and 
outdoor heaters together is because separately, outdoor heaters would 
not meet the threshold for regulation. Id. In addition, AHRI stated 
that MGPs would combine

[[Page 54336]]

multiple product types across both residential and commercial 
applications and that it is unclear if the coverage of outdoor heaters 
is aimed at commercial or residential products. HPBA similarly 
commented that while they are not familiar with non-portable infrared 
patio heaters, the coverage of these products as consumer products is 
not justified because many of these products are overwhelmingly used by 
commercial purchasers. HPBA stated that it appears that these products 
are rarely purchased or used by household consumers. (HPBA, No. 11 at 
pp. 48-49)
    DOE finds that MGPs are similar enough in function and operation 
that it is appropriate to group them together. Decorative hearth 
products are gas-fired products that meet the criteria discussed in 
section II.A of this determination. The definition of decorative hearth 
products groups together all products that perform the same basic 
function--simulating a solid-fuel fireplace and/or presenting an 
aesthetic flame pattern while not being designed to heat the 
surrounding space--regardless of whether they are described in the 
marketplace as being a ``gas fireplace insert'', ``gas log set'', or 
some other term. While products such as gas logs, gas fireplace 
inserts, gas stoves, or other decorative hearth products may have 
distinct operational or design characteristics, DOE finds that the 
products are similar enough in function and operation that it is 
appropriate to group them all under a single definition of decorative 
hearth products for the purposes of this final determination because 
they all serve the same purpose of simulating a solid-fuel fireplace 
and/or presenting and aesthetic flame pattern while not being designed 
to heat the surrounding space. As noted previously, decorative hearth 
products can be designed for indoor or outdoor use (i.e., these 
products include indoor decorative hearth products and outdoor 
decorative hearth products).
    As noted by commenters, all hearth products, including those that 
are decorative and are not designed to provide a significant amount of 
heat to the surrounding space, produce some amount of heat even if it 
is not their primary function. Grouping indoor decorative hearths and 
outdoor decorative hearths is appropriate because, as noted, they have 
similar forms and functions. Outdoor hearths and outdoor heaters are 
also similar in that they are gas-fired products that are used outdoors 
and may provide aesthetic value to consumers (in particular, outdoor 
hearths and outdoor heaters with visible flames may be considered 
substitute products for many consumers), and therefore grouping these 
products is also appropriate. Outdoor heaters without flames are very 
similar to those with flames. DOE's analysis of MGPs as a covered 
products assessed outdoor heaters, which it defines as products that 
are gas-fired appliances designed for use in outdoor spaces only, and 
which are designed to provide heat proximate to the unit. Some outdoor 
heaters meeting DOE's definition have visible flames and some do not.
    Furthermore, DOE disagrees with the assertion that its motivation 
in grouping these products was related to annual energy use thresholds. 
As discussed above, DOE believes these products are appropriately 
grouped based on their function and operation. In the February 2022 
NOPD, DOE estimated that both outdoor heaters and decorative hearth 
products individually meet the energy use threshold under 42 U.S.C. 
6292(b)(1)(B). 87 FR 6792. Aggregate annual energy use was not a factor 
in determining the scope of MGPs. Should DOE proceed with a rulemaking 
to establish energy conservation standards, DOE would determine if MGPs 
satisfy the energy use threshold provisions at 42 U.S.C. 6295(l)(1) 
during the course of that rulemaking.
    DOE did not include ANSI safety certifications into its definitions 
of miscellaneous gas products, decorative hearth products, or outdoor 
heaters because DOE understands that many hearth products could be 
certified to various or multiple standards, and defining product 
classifications based on the safety standard could allow products to 
change classification if their certification standard were changed. 
Additionally, it could be possible for hearth products to not indicate 
the ANSI standard to which it is certified.
    In response to the suggestion that many outdoor heaters would more 
appropriately be classified as commercial products, DOE notes that EPCA 
defines ``consumer product,'' in part, as an article that ``to any 
significant extent, is distributed in commerce for personal use or 
consumption by individuals.'' (42 U.S.C. 6291(1)). Standards 
established for MGPs as a consumer product under EPCA would, therefore 
apply to any MGP distributed to any significant extent as a consumer 
product for residential use. Although many outdoor heaters (and other 
types of MGPs) can be used in commercial settings, they are 
appropriately classified as consumer products because many of these 
products are also distributed in commerce for residential use.
4. Propane Products
    In response to the February 2022 NOPD, HPBA commented that although 
the coverage of any MGPs is not warranted; coverage for propane-fueled 
products would be even harder to justify for many of these products. 
(HPBA, No. 11 at p. 51) HPBA added that many prefabricated outdoor 
fireplaces use propane as fuel, and consumers are directed to close the 
valves on the propane cylinders when the product is not in use and the 
potential for unnecessary pilot light use would be limited by the 
volume of the cylinder. (Id. at pp. 45, 53)
    OGC commented that propane-fueled decorative hearth products and 
outdoor heaters should not be within the scope of coverage because the 
relatively high cost of propane and the user understanding that 
products operated on bottled propane are operated on a limited supply 
of fuel already encourages users to practice energy conservation and 
monitor their usage. (OGC, No. 8 at p. 2) AHRI commented that for 
portable or free-standing propane heaters, it would be unlikely that a 
standing pilot would be left on as it would drain the propane tank when 
the heater was not in use. (AHRI, No. 16, p. 5) Similarly, HHT and NPGA 
commented that propane fuel usage is already regulated by the size of 
the container it is sold in or used out of. (HHT, No. 9 at p. 2; NPGA, 
No. 14 at p. 4) Therefore, NPGA concluded that the energy use of 
propane-fueled decorative hearth products or outdoor heaters is 
determined by the consumer rather than an efficiency standard. (NPGA, 
No. 14 at p. 4)
    Conversely, Moroz commented that the inclusion of propane-fueled 
decorative hearth products and outdoor heaters should be done only to 
harmonize with NRCan regulations for hearth appliances. (Moroz, No. 7 
at p. 2) AGH commented that they support the inclusion of propane 
products within the scope of the proposed coverage determination of 
MGPs. The commenter stated that stoves and fireplaces that use propane 
are often nearly identical to ones that use natural gas and are very 
popular in areas not served by gas pipelines. AGH stated that companies 
that produce natural gas appliances also produce propane appliances and 
the regulation of one without the other would create a confusing and 
artificial distinction. AGH added that the cost of propane is typically 
higher than natural gas; therefore, consumers could benefit from 
transparent and minimum efficiency ratings. (AGH, No. 10 at p. 2) The 
Joint Commenters also expressed

[[Page 54337]]

their support for the inclusion of propane products in the scope of 
proposed coverage determination for MGPs. (Joint Commenters, No. 13 at 
p. 1) The Joint Commenters referenced a 2017 Lawrence Berkley National 
Laboratory Hearth Study that showed that 59 percent of hearth products 
use natural gas and 17 percent use propane and suggested that they 
expect the proportion of decorative hearth products that use propane to 
be similar and that the inclusion of propane products may represent 
significant energy savings. The Joint Commenters also noted their 
market review findings that one large retailer listed 151 models of 
propane-fueled units and 23 models of natural gas-fueled outdoor 
heaters while another large retailer's website listed 352 models of 
propane-fueled units and 56 models of natural-gas fired outdoor 
heaters. (Id. at pp. 1-2)
    DOE defines the term ``gas'' to mean either natural gas or propane 
in 10 CFR 430.2. Therefore, based on the existing definition of 
``gas,'' MGPs would include propane-fueled outdoor heaters and 
decorative hearth products. However, should test procedures and energy 
conservation standards for MGPs be considered in the future, DOE may 
consider whether propane-fueled products warrant different treatment 
under test procedures and energy conservation standards than natural 
gas-fueled MGPs.
5. Unvented Hearth Products
    OGC commented that unvented indoor products must be certified to 
ANSI Z21.11.1 and that whether the product is used primarily as heat or 
for its decorative qualities is determined by the user. (OGC, No. 8 at 
p. 3) Moroz commented that because the heat from combustion in an 
unvented gas fireplace is distributed into the surrounding living 
space, it is appropriate for them to be classified as heaters. (Moroz, 
No. 7 at p. 2) HHT stated that they are not aware of any unvented 
hearth product that is solely decorative and that the ability of a 
product to provide sufficient heat for a space is dependent on the 
space in which it is installed. HHT stated that it is not aware of any 
characteristics that differentiate purely decorative unvented indoor 
hearth products from unvented heaters. (HHT, No. 9 at p. 2) HPBA stated 
that heating output does not provide a distinction between different 
categories of vent-free fireplaces or log sets. (HPBA, No. 11 at p. 51) 
HPBA stated that vent-free gas fireplaces and log sets, which have an 
inherently high heating efficiency because they release all of their 
heat to the space, may be chosen because of ease of installation or 
because they may be the only practical option. (Id. at pp. 51-52) DOE 
is not aware of any purely decorative unvented hearth products and 
agrees that unvented indoor products are not decorative hearth products 
as defined in this determination. Hearth heaters, including unvented 
hearth heaters, are separately regulated products and DOE is in the 
process of considering standards for these products in a separate 
rulemaking (see docket EERE-2022-BT-STD-0018).
6. ANSI Standard Certifications
    In response to the February 2022 NOPD, HHT commented that the 
following industry standards should be reviewed for the coverage 
determination for decorative hearth products and outdoor heaters: ANSI 
Z21.50, Z21.84, Z21.11, Z83.26, Z21.60, Z21.97, Z83.19. (HHT, No. 9 at 
p. 1) OGC commented that the industry standards covered in the February 
2022 NOPD are adequate to cover the different product types identified. 
(OGC, No. 8 at p. 1)
    DOE reviewed the scope of ANSI Z21.50, ANSI Z21.60, ANSI Z21.84, 
ANSI Z21.97, and ANSI Z83.26 to inform the proposed scope of coverage 
of MGPs in the February 2022 NOPD. 87 FR 6786, 6788-6789. DOE has also 
since identified products certified to ANSI Z21.11 and ANSI Z83.19 and 
reviewed the scope of these standards as well. As appropriate, DOE used 
provisions from these ANSI standards to inform its understanding of 
appropriate product categorizations, but, as discussed in section 
II.A.3, DOE did not include ANSI safety certifications into its 
definitions of miscellaneous gas products, decorative hearth products, 
or outdoor heaters because this could lead to inconsistent 
classifications.

B. Other Comments Received

1. Indoor Heating Products
    HPBA asserted that no gas fireplace products qualify as DHE. The 
commenter added that fireplace products are not included in any of the 
16 DHE product categories, nor do they resemble products that are DHE. 
Further, HPBA stated that EPCA does not give DOE authority to create 
additional categories of DHE. (HPBA, No. 11 at pp. 19-21)
    DOE notes that MGPs are a separate consumer product category from 
DHE, and that DHE are not at issue in this coverage determination 
rulemaking. Indeed, in its decision for Hearth, Patio & Barbecue 
Association v. Department of Energy, et al. 706 F.3d 499 (D.C. Cir. 
2013), the United States Court of Appeals for the District of Columbia 
Circuit held that the phrase ``vented hearth heater'' did not encompass 
decorative fireplaces as that term is traditionally understood. As 
discussed in the February 2022 NOPD, DOE believes that classifying 
vented hearth heaters as vented home heating equipment would be 
consistent with the Court's opinion, in that vented hearth heaters 
provide space heating. Therefore, DOE concluded that although there are 
not currently energy conservation standards for vented hearth heaters, 
these products are appropriately covered as vented home heating 
equipment (and DHE). 87 FR 6786, 8688. However, MGPs do not include 
vented hearth heaters. Thus, DOE is not creating an additional category 
of DHE through this coverage determination, but rather is establishing 
a new category of separately covered products consistent with its 
authority under EPCA.
    HPBA further commented that heating efficiency standards for vented 
gas fireplaces would limit the range of available products and leave 
many consumers without vented gas fireplaces appropriate for their 
needs but would not make such products better or more efficient gas 
fireplaces. (HPBA, No. 11 at pp. 27-28) HPBA explained that the core 
appeal of fireplaces is ``not in their heating utility per se, but in 
the unique combination of features that make a fireplace a fireplace.'' 
(Id.)
    DOE notes that consumer utility impacts of standards for vented gas 
fireplaces will be considered in any future energy conservation 
standards rulemaking, including the aesthetic appeal of fireplace 
features.
    HPBA commented that vented gas fireplaces do not produce 
particulate emissions that are often characteristic of many older solid 
fuel fireplaces which, they stated, makes them more desirable from an 
air quality standpoint, particularly in the homes of individuals with 
respiratory problems such as asthma. (HPBA, No. 11 at p. 29) HPBA 
stated that, while vented gas fireplaces can have significant heating 
utility, few consumers regularly use their fireplace heaters for 
utilitarian heating purposes, and very few do so exclusively. The 
commenter added that better space heating options exist that are both 
less costly and better tailored for the purposes of strictly 
utilitarian heating use. (Id. at pp. 29-30)
    HPBA stated that the market for fireplaces with very high 
efficiency is small because there is little or no demand for fireplaces 
that generate too much heat. HPBA stated that one of their members 
found it possible to make

[[Page 54338]]

fireplaces that utilize condensing technology to reach high heating 
efficiency but that the market was insufficient to sustain production 
of condensing gas fireplaces. (HPBA, No. 11 at p. 30)
    In response to DOE's request for comments on outdoor hearth 
products designed to provide a large amount of heat, HPBA commented 
that a fireplace or similar product does not exist that is designed to 
provide a large amount of heat as its primary function. HPBA stated 
that the primary function of a fireplace or similar product is to be a 
fireplace or similar product. HPBA stated that although it is often 
part of the appeal that such products produce heat, their purpose is to 
be enjoyed. HPBA further added that the enjoyment is undermined if too 
much heat is produced. HPBA also commented that the heat output of 
fireplaces and similar products does not provide reasonable basis for 
characterization of such products as ``heaters'' for purposes of 
efficiency regulation. (HPBA, No. 11 at p. 49).
    DOE notes that the definitions for MGPs cover products, in part, 
depending on whether or not it is designed to provide heating to the 
space in which it is installed. Regardless of the utilization of the 
product by the end consumer, the designed intention of the product by 
the manufacturer can be classified as to whether it is intended to 
provide heating. It is on this basis that DOE is not excluding vented 
gas fireplaces from the definition of decorative hearth products, as 
DOE's market research found that vented gas fireplace products that are 
not designed to provide space heating are available on the market.
    AGH commented that efficiencies of gas stoves are often unavailable 
and confusing and that the database maintained by the Canadian 
government is the only reliable source for gas stove efficiencies. 
(AGH, No. 10 at p. 1) AGH stated that their interactions with retailers 
and manufacturers yielded contradictory and inaccurate information. AGH 
concluded that consumers should be cautious of efficiency claims from 
manufacturers and retailers and suggested that the Canadian database is 
more reliable. AGH commented that consumers who want to save on heating 
bills often use their gas stove or fireplace to heat the core of the 
house instead of the furnace to heat the entire house. AGH stated that 
gas fireplaces and stoves are often used to provide heat to homes as 
either a primary or secondary heat source; additionally, they stated, 
many retailers advertise that gas inserts can easily serve as the 
primary source of heat for a home and cited a manufacturer's claim that 
gas inserts can use ``50 [percent] to 90 [percent] less gas than gas 
logs and up to 75 [percent] less gas than a gas furnace.'' \11\ 
Additionally, AGH stated that gas furnaces can waste up to 30 percent 
of their heat from leaking ducts. AGH concluded from this information 
that consumers could save significant amounts of money and gas if gas 
fireplaces and stoves are regulated under EPCA. (Id. at pp. 1-2)
---------------------------------------------------------------------------

    \11\ AGH cited a blog post by Karen Duke titled ``Is a Gas 
Fireplace Worth It?'' See www.victorianfireplaceshop.com/is-a-gas-fireplace-worth-it.
---------------------------------------------------------------------------

    DOE conducted market research through which the DOE identified both 
gas stove products that are intended to provide space heating and gas 
stove products that are not intended to provide space heating. 
Therefore, DOE is not excluding all gas stoves from coverage as MGPs. 
DOE notes that any indoor gas stove that is designed to heat the space 
in which it is installed does not meet the criteria outlined in the 
definition of a decorative hearth product and will thereby not be 
covered as MGP.
2. Shipments
    AGH raised concerns that DOE may have underestimated the annual 
shipments of MGPs by relying on data from HPBA. AGH commented that 
HPBA's estimates only include appliance shipments by their member 
companies. They further suggested that even member companies may choose 
not to provide data and that some of the largest gas appliance 
manufacturers have dropped their HPBA membership in recent years. (AGH, 
No. 10 at p. 2) The Joint Commenters stated their belief that the DOE 
may be underestimating the annual shipments of MGPs because although it 
was stated in the February 2022 NOPD that the hearth product shipments 
were scaled from the technical support document (``TSD'') that 
accompanied a notice of proposed rulemaking (NOPR) proposing energy 
conservation standards for hearth products published on February 9, 
2015 (80 FR 7082) (``the February 2015 NOPR'') \12\ (``the February 
2015 NOPR TSD''), they stated that it was unclear what the scaling 
factor was intended to represent and that the hearth product shipments 
reported by HPBA appear to be significantly higher than those in Table 
9.3.1 of the February 2015 NOPR TSD. (Joint Commenters, No. 13 at p. 2) 
Further, the Joint Commenters stated that shipments of MGPs may have 
increased significantly due to the COVID-19 pandemic, and it is 
therefore, believed by the commenters that the number of annual 
shipments is underestimated by DOE. (Id.)
---------------------------------------------------------------------------

    \12\ On March 31, 2017, DOE withdrew a proposed determination of 
coverage for hearth products that was published on December 31, 2013 
(78 FR 79638) in the bi-annual publication of the DOE Regulatory 
Agenda. (82 FR 40270, 40274 (August 24, 2017)) This withdrawal, in 
effect, revoked the February 2015 NOPR.
---------------------------------------------------------------------------

    The CA IOUs added that the use of hearth products is continuing to 
increase in California and is anticipated to do so through the year 
2035. (CA IOUs, No. 12 at p. 1)
    DOE notes that it used the shipment data available at the time of 
the February 2022 NOPD to develop the estimates of energy consumption. 
In the Request for Information on Energy Conservation Standards for 
Miscellaneous Gas Products published on June 14, 2022 (``June 2022 
RFI''),\13\ DOE requested updated shipment figures for decorative 
hearth products and outdoor heaters. 87 FR 35925. In response to the 
Joint Commenters, DOE notes that the shipment data for gas appliances 
reported by HPBA comprise more products than only decorative hearths, 
therefore some of the HPBA shipments are excluded from DOE's estimates 
for decorative hearths. HPBA provided DOE with shipments of hearth 
products for the February 2015 NOPR, which are available in Chapter 9 
of the February 2015 NOPR TSD. These shipments reflect the number of 
decorative hearths and hearth heaters shipped by HPBA members from 2005 
to 2013. DOE took these shipments and compared them to overall gas 
appliance shipments reported by HPBA \14\ during that time and, on 
average, decorative hearths and hearth heaters accounted for 68 percent 
the HPBA reported total annual hearth industry shipments. DOE applied 
this 68 percent to HPBA shipments of gas appliances beyond 2013 \15\ to 
develop a stock of hearth heaters and decorative hearths in 2022. To 
develop a stock of decorative hearths for the February 2022 NOPD, DOE 
assumed that 39 percent of total decorative hearths and hearth heater 
shipments were decorative. This is the same percentage that was used to 
estimate decorative shipments in the analysis supporting the February 
2015 NOPR. DOE understands that the COVID-19 pandemic may have 
increased the demand for MGP products including outdoor heaters and DOE 
may

[[Page 54339]]

consider future growth of product shipments in a standards analysis.

3. Energy Use Analysis
    OGC commented that DOE needs to demonstrate that an improvement in 
efficiency is feasible to conserve energy resources in order to cover a 
product, which OGC stated had not been done in the proposed 
determination. (OGC, No. 8 at p. 2) NPGA stated that they were unable 
to evaluate the potential benefits, energy savings, or improvements for 
consumers because the scope of products potentially subject to the 
February 2022 NOPD is overly broad. (NPGA, No. 14 at pp. 2, 3, and 5)
    HPBA commented that the ``outdoor heater'' and ``decorative 
hearth'' definitions are not clear enough to know which product 
operating hours should be compared. HPBA added that the operative hours 
of ``decorative hearths'' should not be compared to anything because 
the products which are included are too diverse and that the estimate 
of operating hours of ``decorative hearths'' would not be 
representative of any particular product included. (HPBA, No. 11 at pp. 
52-53) Specifically, HPBA commented that fireplaces are architectural 
features that add to the appeal and market value of a home whether or 
not they are used. HPBA added that a substantial percentage of 
fireplaces see little or no active use. (HPBA, No. 11 at pp. 29, 31) 
The CA IOUs commented that the performance standards for MGPs can 
deliver cost-effective savings for Californians and contribute to a 
significant reduction of greenhouse gas emissions nationally. The CA 
IOUs commented that MGPs can operate for many years and stated that 
DOE's assumption that the lifetime of these products is fifteen years 
is supported by analysis and interviews in both California and Canada; 
therefore, they stated, DOE should begin regulation of these products 
as soon as possible. (CA IOUs, No. 12 at p. 1)
a. Ignition Systems
    In response to the February 2022 NOPD, NPGA cautioned the DOE 
against defining scope or standards according to the presence of a 
standing pilot light. NPGA commented that for propane-powered outdoor 
heaters, a push-button or dial control connected to a pilot are 
designed for consumer safety and ease of ignition. NPGA added that 
unlike indoor products powered by natural gas, propane-powered outdoor 
heaters are not designed for pilot lights to remain on indefinitely. 
NPGA stated that clarification is needed as to why the DOE would find 
the ignition system breakdowns for outdoor heaters or standing pilot 
operating hours data for outdoor heaters to be useful information or 
impactful upon energy conservation standards. (NPGA, No. 14 at p. 4)
    OGC commented that ignition systems and operation for outdoor 
products differs from that of indoor products and that DOE's energy 
usage calculations for these products are therefore incorrect. OGC 
stated that outdoor heaters use either an electronic ignition or a 
thermo-electric safety valve. The commenter stated that electronic 
ignition systems either ignite the main burner directly or may ignite a 
pilot burner that ignites the main burner, but the pilot is 
extinguished once the main burner is shut off, and that thermo-electric 
systems typically ignite the main burner directly and use heat from the 
main burner to activate the thermo-electric safety valve. (OGC, No. 8 
at p. 3) HPBA commented that many outdoor gas fireplaces have open 
combustion chambers in which continuous pilot lights have a tendency to 
blow out. HPBA also commented that many prefabricated outdoor 
fireplaces have simple dial and push-button pilot light that is 
designed to be turned on and off manually to facilitate safe main 
burner ignition and pilot light controls that make it easy for 
consumers to avoid unnecessary pilot light use. (HPBA, No. 11 at pp. 
45, 53) HPBA further stated that the potential for such continuous 
pilot lights to be left burning is unknown but likely to be limited. 
(Id. at p. 45) HPBA commented that the pilot lights for these products 
are not designed to be left on indefinitely and would likely burn out 
if they were left burning for an extended period of time. HPBA stated 
that they are not aware of any pilot light operating hours data and 
added that this data serves no purpose for products that are not 
designed to be left with their pilot lights burning indefinitely. (Id. 
at pp. 53-54)
    AHRI commented generally that standing pilots are a practical and 
beneficial solution for units without an outside power source. (AHRI, 
No. 16 at p. 5) Similarly, HPBA commented that, for gas log sets, there 
are physical and mechanical challenges that limit the potential for 
electronic alternatives and the market for these products would likely 
be damaged by a continuous pilot ban. (HPBA, No. 11 at pp. 36-37)
    HPBA stated that outdoor gas log sets are designed to be installed 
in the hearths of existing wood-burning fireplaces and face similar 
challenges as vented gas log sets in transitioning to electronic 
ignition, in that electronic ignition would negatively impact 
aesthetics and the added hardware would be difficult to conceal or 
shield from excessive heat. HPBA added that an increase in cost or 
decrease of appeal in outdoor gas log sets could cause consumers to 
leave conventional wood-burning fireplaces in operation, thereby 
causing adverse environmental impacts. (Id. at p. 43) HPBA also 
commented that a ban on continuous pilot lights for these products 
could have adverse safety impacts because, for outdoor fire pits that 
use continuous pilots, the pilot provides a means to minimize the risk 
of delayed main burner ignition involving the sudden ignition of a 
significant amount of gas. (Id.)
    HPBA commented that when outside temperatures are low, the heat 
from a vented gas fireplace must initially overcome a column of cold 
air in the vent system. HPBA stated that this can present significant 
challenges with longer-vent installations and particularly with more 
heat-efficient designs that employ heat exchangers or flue restrictors 
to raise thermal efficiency and control excess air. HPBA stated that a 
cold-start-up can cause serious operational problems such as start-up 
lag, flame lift, burner outage, draft reversal, and delayed main burner 
ignition. HPBA added that any of these issues would be immediately 
observable by the consumer and can be quite alarming. HPBA stated that 
a pilot light warms the flue and establishes proper draw prior to main 
burner ignition to address all of the listed issues. HPBA commented 
that intermittent pilot ignition (``IPI'') systems with a continuous 
pilot ignition (``CPI'') function were created to address these 
concerns and that in some installations a continuous pilot flame is 
needed to ensure proper product operation. HPBA added that CPI 
functions are used to prevent or resolve operational problems. (Id. at 
pp. 38-39) HPBA stated that the development of ``on demand'' systems 
has made it possible for CPI functions on IPI systems to be converted 
into ``on demand'' functions. (Id. at p. 39) HPBA stated that DOE did 
not include ``on demand'' pilots which were developed to eliminate 
standing pilots in gas fireplace products. HPBA added that these on-
demand ignition systems are currently one of the most common of the 
relevant ignition systems. (Id. at pp. 24-25)
    HPBA commented that gas fireplace products are different in every 
relevant aspect from products such as residential furnaces for which it 
was relatively easy to convert the pilot ignition. HPBA cited the 
following as major the differences: gas fireplaces are typically 
prominently displayed so that the glow of a pilot light is visible when 
the lights are out,

[[Page 54340]]

gas fireplaces are generally ``attended appliances'' for which the main 
burners are used only through the conscious action of the consumer, gas 
fireplaces usually have user-friendly dial and push-button continuous 
pilot light controls, continuous pilot lights provide unique utility 
for gas fireplace consumers, and they have inherent characteristics 
that make the use of IPI technology particularly challenging. (Id. at 
p. 35) HPBA stated that frequent user operation of pilot lights is not 
necessary and that the elimination of pilot lights would affect 
consumer utility. (Id. at p. 36)
    HPBA commented that the industry recognized that the elimination of 
continuous pilot lights could potentially result in energy savings and 
have invested considerable resources to develop alternatives. HPBA 
stated that these efforts have resulted in a dramatic trend away from 
the use of continuous pilots on vented gas fireplaces. (Id.)
    HPBA stated that the use of continuous pilot lights on vented gas 
fireplaces is already being phased out; therefore, HPBA commented that 
the imposition of regulatory burden to hasten market developments is 
unnecessary. (Id. at p. 37) HPBA commented that DOE should consider why 
there hasn't already been widespread adoption of IPI technology 
(without CPI functionality) in the gas fireplace industry, why IPI 
systems with a CPI function and ``on-demand'' ignition systems were 
developed by the gas fireplace industry exclusively to provide an 
alternative to IPI-only systems for vented gas fireplaces, and why some 
retailers have reported that they choose to activate the CPI function 
on IPI products they sell. (Id. at p. 37) HPBA stated that it is 
difficult to ensure that vented gas fireplaces with IPI-only ignition 
systems will not experience potentially significant operational 
problems in some installations. HPBA added that the specific technical 
issues that may occur are related to the differences between vented gas 
fireplaces and the types of products for which IPI systems were 
designed. (Id. at pp. 37-38)
    HPBA stated that gas fireplaces and log sets are so materially 
different from each other that combined data on the proportion of 
ignition system types for both products would be wildly inaccurate as 
applied to either. (Id. at p. 19)
    HPBA stated that they explored an initiative to eliminate 
continuous pilot lights on a wide range of outdoor gas products and 
determined that it would have little potential to conserve energy and 
would have undesirable collateral safety impacts. (Id. at p. 45)
    The CA IOUs stated that the California Energy Commission (``CEC'') 
determined that, using an assumption of 1,000 Btu/hour for gas burners 
and annual standing pilot operating hours of 4,612 hours per product, 
decorative hearth products and outdoor gas fireplaces will provide cost 
effective energy savings that will exceed the thresholds set by 42 
U.S.C. 6292 (b)(1) and 42 U.S.C. 6295(l). The CA IOUs stated that using 
the CEC's assumptions, standing pilots used 4,161,569 Btu/year per unit 
which is equivalent to 1,219 kWh and exceeds the requirements to set 
standards under EPCA. (CA IOUs, No. 12 at p. 2) The CA IOUs stated that 
a CEC analysis determined that decorative hearth products with an on-
demand pilot light used 1,747,755 Btu/year while decorative hearths 
with intermittent pilot energy used only 188,882 Btu/year. The CA IOUs 
also stated that the CEC determined that intermittent pilot light 
technologies are readily available. The CA IOUs stated the feasibility 
and savings that were demonstrated support that federal regulation of 
these products is consistent with the purposes of EPCA. (Id.)
    In response to concerns about potential standards that could 
eliminate the use of continuous pilot lights or regulate other ignition 
systems in the future, DOE notes that the current coverage rulemaking 
is only to determine whether coverage of MGPs is necessary or 
appropriate to carry out the purposes of EPCA, as discussed in section 
I.A. DOE maintains that patio heaters fall under the proposed 
definition of outdoor heaters and, by extension, MGPs, regardless of 
the type of ignition used in the product. DOE is not proposing 
standards for MGPs in this final determination of coverage. Comments 
regarding the benefits and obstacles for potential standards for MGPs 
will be considered in a separate energy conservation standards 
rulemaking.\16\

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

    In response to comments on the energy use estimates, DOE notes that 
it did not use the same operating characteristics for indoor decorative 
hearth pilot operation and outdoor heater pilot operation. DOE 
understands that a large percentage of outdoor heaters are propane, 
however, there are fixed outdoor heaters on the market. DOE adjusted 
the standing pilot hours and the percentage of standing pilots of 
decorative hearths to make an estimate of ignition energy use for 
outdoor heaters. In DOE's energy consumption estimate, it was assumed 
that only around 10 percent of outdoor heaters kept the pilot on when 
the main burner was not operating and the standing pilot hours were 
reduced to account for the fact that outdoor heaters are likely more 
seasonal than decorative hearths. In the February 2022 NOPD, DOE 
requested comment on the breakdown of ignition systems and standing 
pilot operating hours for outdoor heaters, and received no data. 87 FR 
6786, 6792.
    In response to the CA IOUs, DOE notes that the energy consumption 
analysis in the February 2022 NOPD was developed to determine if 
coverage of MGPs was warranted under 42 U.S.C. 6292(b). DOE will 
consider the technical feasibility, energy savings, and economic 
justification of various technologies in a standards rulemaking.
b. Main Burner Operation
    OGC and HHT stated that outdoor conditions vary greatly from season 
to season as well as by location and climate. (OGC, No. 8 at p. 3; HHT 
No. 9 at p. 3) OGC expressed concerns that DOE assumes outdoor 
decorative products are operated regardless of the outdoor ambient 
temperature without data to substantiate that assumption. (OGC, No. 8 
at p. 3) Moroz stated that they are not aware of any data representing 
the operating hours of either outdoor heaters or decorative hearth 
appliances. (Moroz, No. 7 at p. 2) OGC added that they are unaware of 
available data on outdoor usage or energy consumption and that the 
operating characteristics for outdoor heaters, indoor decorative 
products, and outdoor decorative products are likely to be different. 
(OGC, No. 8 at p. 3)
    NPGA stated in response to the February 2022 NOPD, that energy 
usage was estimated according to outdated survey information. NPGA also 
stated that decorative hearth products and outdoor heaters are 
intrinsically produced for different uses by consumers. NPGA commented 
that the data and surveys collected in past years were not administered 
according to the proposed product definition presented in the current 
notice and therefore, urged the DOE to issue an RFI for more data and 
present the data and proposed definitions for stakeholders in a new 
notice. (NPGA, No. 14 at pp. 2-3) NPGA commented that the DOE should 
pursue the most recent and up-to-date data on energy usage and 
manufacturing production because this information is crucial to 
determining if these products

[[Page 54341]]

use enough energy to meet the threshold for regulation under EPCA. (Id. 
at p. 2)
    AHRI also stated that they do not view the prescription of decorate 
hearth usage data to outdoor heaters to be a valid assumption. AHRI 
further added that the consumer survey used to estimate decorative 
hearth usage may be questionable because all of the estimates were 
derived from a single survey. AHRI noted that the survey (although 
published in June of 2017) was conducted in February of 2016, there was 
no mechanism for respondents to confirm ownership of the equipment in 
question, and it was not confirmed that the respondents ``subjective 
answers'' reflected the manufacturers' design for decorative hearth 
equipment. (AHRI, No. 16 at pp. 3-4)
    The Joint Commenters stated that it is not clear in the February 
2022 NOPD whether match-lit units were included in the national energy 
use calculation. (The Joint Commenters, No. 13 at p. 2)
    HPBA suggested that heating standards would be problematic because 
increasing heating efficiency and thus heat output can lead to more 
heat output than is desired. HPBA further suggested that even 
moderately high heating efficiency standards could substantially reduce 
the number of fireplaces appropriate to a given installation. 
Additionally, HPBA stated that an increase in heating efficiency cannot 
be expected to produce energy savings by reducing the burner operating 
hours required to satisfy heating needs. (HPBA, No. 11 at pp. 31-34)
    DOE notes that the average operating hours for decorative hearths 
from the February 2022 NOPD was based on operating data for both indoor 
decorative hearths and outdoor decorative hearths from a 2017 survey by 
the Lawrence Berkeley National Laboratory (``2017 hearth survey'').\17\ 
There was no assumption that outdoor decorative hearths operate the 
same regardless of outdoor air temperatures; the national average was 
creating by averaging the operating hours for decorative products (both 
indoor and outdoor) by region. DOE lacked data on the operation of 
outdoor heaters at the time of the February 2022 NOPD. The 2017 Hearth 
Survey provided estimates of main burner hours for decorative hearths 
and hearth heaters and noted a positive correlation between the main 
burner operating hours and utility for heat. DOE used the decorative 
hearth burner operating hours for outdoor heaters as those were the 
smallest amount of operating hours in the survey and therefore 
constitutes a conservative estimate. While DOE understands that the 
operating characteristics of decorative hearths and outdoor heaters may 
vary, given that large portions of the U.S. have long periods of cooler 
temperatures, it is unlikely that outdoor heaters would operate 
significantly less than what was assumed in the February 2022 NOPD. As 
DOE did not receive any data on the operating hours of decorative 
hearths or outdoor heaters, DOE did not change its estimates of 
national and household energy consumption.

Analysis and Environmental Impacts Division, Lawrence Berkeley 
National Laboratory. June 2017. eta.lbl.gov/publications/survey-hearth-products-us-homes.
---------------------------------------------------------------------------

    DOE also notes that the 2017 Hearth Survey is the most 
comprehensive study of hearth products in the United States. While the 
respondent's answers were subjective, DOE has confidence in the survey 
because the percentage of products identified as decorative or mostly 
decorative (38 percent) is consistent with the percentage of total 
hearth shipments that were decorative (39 percent) from the February 
2015 NOPR.
    In response to the Joint Commenters, the main burner energy 
consumption of match-lit products was included in the national energy 
use calculation.
    This coverage determination rulemaking is only to determine whether 
coverage of MGPs is necessary or appropriate to carry out the purposes 
of EPCA, as discussed in section I.A. DOE is not proposing standards 
for MGPs in this final determination of coverage. DOE may consider the 
impacts of standards on consumer utility in a future energy 
conservation standards rulemaking.
4. Economic Analysis
    The Gas Associations commented that it is important that the DOE 
implement the recommendations from the recent National Academies of 
Sciences, Engineering, and Medicine (``NASEM'') report \18\ into all of 
its appliance rulemakings. In particular, the Gas Associations 
recommended, based on the NASEM report, that DOE should pay greater 
attention to economic justification for the standards as required by 
EPCA and, to conclude that standards are economically justified, DOE 
should attempt to find significant failures of private markets or 
irrational behavior by consumers in the no-standards case. 
Additionally, the Gas Associations recommended that the DOE expand the 
Cost Analysis segment of the Engineering Analysis to include ranges of 
costs, patterns of consumption, diversity factors, energy peak demand, 
and variance regarding environmental factors. The Gas Associations also 
recommended that the DOE give greater weight to ex post and market-
based evidence of markups in order to project more accurate effects of 
a standard on prices. (Gas Associations, No. 15 at p. 2)

Setting Appliance and Equipment Standards. NASEM (2021). Available 
at: nap.nationalacademies.org/read/25992/chapter/1.
---------------------------------------------------------------------------

    The Gas Associations recommended that DOE provide an argument for 
the plausibility and magnitude of potential market failure related to 
the energy efficiency gap in its analysis. They added that there should 
be a presumption that the market actors behave rationally, unless DOE 
can provide evidence to the contrary. The Gas Associations also 
recommended that DOE should give greater attention to a broader set of 
potential market failures on the supply side. They stated that this 
should include how standards might reduce the number of competing firms 
and how they might impact price discrimination, technological 
diffusion, and collusion. (Id.)
    In response to the Gas Associations recommendations for the 
economic analysis, DOE notes that the current coverage rulemaking is 
only to determine whether coverage of MGPs is necessary or appropriate 
to carry out the purposes of EPCA. Economic considerations would be 
analyzed as part of an energy conservation standard rulemaking.
5. Process-Related Comments
    In response to the February 2022 NOPD, the CA IOUs agreed with 
DOE's tentative finding that the coverage of MGPs is necessary and 
appropriate to carry out the purposes of EPCA. (CA IOUs, No. 12 at p. 
1) The Joint Commenters also indicated their support of DOE's 
determination that decorative hearths and outdoor heaters qualify as 
MGPs covered under EPCA. However, the Joint Commenters encouraged DOE 
to not finalize the proposed determination until energy conservation 
standards have been finalized, since information that is learned during 
the rulemaking process for both test procedures and energy conservation 
standards can ultimately inform the coverage determination. (Joint 
Commenters, No. 13 at p. 1)
    HPBA and APGA requested that DOE further explain its proposal with 
specific regard to the identification of the specific product for which 
coverage is proposed, and why (and how) DOE

[[Page 54342]]

believes that it would be appropriate to regulate each of those 
products. (HPBA, No. 2 at pp. 1-2; APGA, No. 5 at pp. 1-2)
    HPBA and AGA requested that DOE hold a public meeting to clarify 
its current proposal. (HPBA, No. 2 at p. 1; AGA, No. 4 at p 2) HPBA 
requested the opportunity to present specific recommendations 
concerning DOE's basic regulatory approach to facilitate a constructive 
exchange of information and ideas. (HPBA, No. 2 at pp. 2-3) 
Additionally, HPBA included in their comments a resubmission of the 
comments they submitted on May 11, 2015, in response to the February 
2015 NOPR as evidence to support their claim of inadequate 
informational exchange. (Id. at p. 10) HPBA also added that DOE is 
behind on statutory deadlines for regulatory actions on numerous 
products that it has a mandatory duty to complete and therefore it is 
not ``necessary'' or ``appropriate'' for DOE to regulate MGPs. (Id. at 
p. 54) AGA commented that the rulemaking history in this proposal and 
the unaddressed concerns of stakeholders makes a public meeting 
appropriate. AGA added that the meeting should address concerns 
including outstanding coverage determinations, whether there is a 
justifiable basis for regulating covered products, and how covered 
products may be regulated. (AGA, No. 4 at pp. 1-2)
    In response, DOE notes that although the scope of the February 2015 
NOPR differed from the current coverage determination, many insights 
from that rulemaking (for example, information about technology options 
that are also relevant to MGPs) informed the current coverage 
determination. Additionally, DOE responds that stakeholders were given 
the opportunity to provide written comments in response to the proposed 
coverage determination, which DOE determines to be a sufficient 
opportunity to provide feedback. Moreover, as noted above, this 
rulemaking only establishes coverage for MGPs. DOE's authority and 
responsibility to determine the coverage of MGPs is distinct from its 
authority under EPCA. Prior to the adoption of any energy conservation 
standards or test procedures for these products, stakeholders will have 
additional opportunities for comment, including a public meeting(s).
    The Gas Associations commented that the proposed coverage 
determination of MGPs is neither necessary nor appropriate within the 
meaning of 42 U.S.C. 6292(b)(1)(A). They added that DOE has not 
provided sufficient evidence to demonstrate economic justification or 
significant energy savings for an efficiency standard for MGPs. (Gas 
Associations, No. 15 at pp 2-3) They stated that the February 2022 NOPD 
treated broad categories of different products as though they are a 
single product and recommended the withdrawal of the proposed coverage 
determination for reconsideration. (Id. at p. 3) OGC commented that the 
coverage of ``miscellaneous gas products'' is not necessary or 
appropriate to carry out the purposes of EPCA and that it is too broad 
to justify coverage under EPCA. (OGC, No. 8 at p. 3) OGC and HHT 
further commented that the information and analysis in the February 
2022 NOPD are inadequate to support the issuance of a determination for 
MGPs. Consequently, OGC recommended that the proposed determination be 
withdrawn and treated as an RFI to allow for more collaboration with 
industry to properly determine what is considered a covered product. 
(OGC, No. 8 at p. 1; HHT, No. 9 at pp. 1, 3)
    Similarly, HPBA requested that the DOE withdraw the February 2022 
NOPD and discontinue any further regulatory efforts with respect to gas 
fireplaces, fireplace inserts, freestanding stoves, gas log sets, 
outdoor gas products designed to have visual appeal (fire pits, fire 
tables, tiki torches, patio heaters that double as outdoor lighting or 
flame art, and pure objects of flame art), and strictly utilitarian 
portable patio heaters. HPBA added that coverage for the listed 
products is neither ``necessary'' nor ``appropriate'' within the 
meaning of 42 U.S.C. 6292(b)(1)(A) and was not proven otherwise by the 
February 2022 NOPD. HPBA stated that there is no potential for energy 
savings or economic justification that could be provided by efficiency 
standards for these products and that these products are unsuitable 
targets for efficiency regulation. (HPBA, No. 11 at p. 1) HPBA 
commented that the DOE's attempt to establish coverage of MGPs is not 
supported by EPCA and stated that the February 2022 NOPD did not 
provide a reasonable basis to conclude that MGPs are worth regulating. 
(Id. at pp. 13-15) HPBA stated that DOE should follow the direction of 
Executive Order 13563 and ensure that it has incorporated information 
and perspectives from those who are likely to be affected by the 
proposal. (Id. at p. 12) HPBA stated that coverage determinations must 
be product-specific and that to establish that coverage is warranted, 
DOE must demonstrate that the product is not a ``gnat'' and explain why 
regulation of that product is ``necessary'' or ``appropriate'' to carry 
out EPCA's purposes. HPBA also stated that there is insufficient data 
and information used for the analysis. They added that data collection 
should be the first step in the development of a rule. HPBA stated that 
the pace of technological and market changes has made it so information 
concerning the prevalence of continuous pilot lights becomes quickly 
outdated. HPBA commented that while they have not had sufficient 
opportunity to review the basis of the DOE's claims, they stated that 
the February 2022 NOPD is based on inaccurate information, inadequate 
data, and arbitrary assumptions. (Id. at pp. 24-25)
    DOE notes that Part A of Title III of EPCA, 42 U.S.C. 6291 et seq., 
authorizes DOE to classify additional types of consumer products as 
covered products upon determining that: (1) classifying the product as 
a covered product is necessary or appropriate for the purposes of EPCA; 
and (2) the average annual per-household energy use by products of such 
type is likely to exceed 100 kilowatt-hours per year (kWh/yr). (42 
U.S.C. 6292(b)(1)). DOE's evaluation of MGPs under this standard is 
discussed in section II.C of this determination.

C. Evaluation of Miscellaneous Gas Products as Covered Products

    DOE evaluated whether MGPs, which are comprised of decorative 
hearth products and outdoor heaters, are ``consumer products'' under 
EPCA. As discussed in section I of this document, a consumer product is 
any article (other than an automobile) of a type--(A) which in 
operation consumes, or is designed to consume energy; and (B) which, to 
any significant extent, is distributed in commerce for personal use or 
consumption by individuals; without regard to whether such article of 
such type is in fact distributed in commerce for personal use or 
consumption by an individual. (42 U.S.C. 6291(a)(1)) MGPs consume 
energy during operation and are distributed in commerce for personal 
use by individuals. Therefore, DOE has determined that MGPs are 
consumer products within the scope of EPCA.
    The following sections describe DOE's evaluation of whether MGPs 
fulfill the criteria for being added as covered products pursuant to 42 
U.S.C. 6292(b)(1). As stated previously, DOE may classify a consumer 
product as a covered product if:
    (1) Classifying products of such type as covered products is 
necessary or appropriate to carry out the purposes of EPCA; and

[[Page 54343]]

    (2) The average annual per-household energy use by products of such 
type is likely to exceed 100 kWh (or its Btu equivalent) per year.
1. Coverage Necessary or Appropriate To Carry Out the Purposes of EPCA
    DOE has determined that coverage of MGPs is necessary or 
appropriate to carry out the purposes of EPCA, which include:
    To conserve energy supplies through energy conservation programs, 
and, where necessary, the regulation of certain energy uses; and
    To provide for improved energy efficiency of motor vehicles, major 
appliances, and certain other consumer products. (42 U.S.C. 6291(4)-
(5))
    DOE estimates that annual shipments of MGPs have averaged 
approximately 190,000 units per year from 2016 to 2020.\19\ DOE 
estimates that the aggregate national energy use of decorative hearth 
products is 0.0135 quadrillion British thermal units (``quads'') (4.0 
Terawatt-hours (``TWh'')),\20\ and that the aggregate national energy 
use of outdoor heaters is estimated to be 0.0007 quads (0.2 TWh).\21\ 
DOE estimates that the aggregate national energy use of decorative 
hearth products and outdoor heaters, comprising MGPs, is 0.0143 quads 
(4.2 TWh). Coverage of MGPs would result in the conservation of energy 
supplies through the regulation of energy efficiency. Therefore, DOE 
has determined that coverage of MGPs is necessary and appropriate to 
carrying out the purposes of EPCA, thereby satisfying the provisions of 
42 U.S.C. 6292(b)(1)(A).
---------------------------------------------------------------------------

    \19\ This estimate was developed by scaling the average hearth 
product shipments from 2010-2013 on page 9-2 of Chapter 9 in the 
February 2015 NOPR Technical Support Document to the total HPBA gas 
appliance shipments from 2010 to 2013 and applying that average to 
the total gas appliance shipments to the 2016 through 2020 shipments 
from HPBA (www.hpba.org/Resources/Annual-Historical-Hearth-Shipments). Manufacturer interviews conducted for the February 2015 
NOPR analysis were used to develop the market share of decorative 
hearths (39%) and outdoor heaters (3%) from total shipments. The 
market shares were assumed to remain constant from 2016-2020.
    \20\ The aggregate national energy use of decorative hearths is 
based on energy use estimates developed in section V.B of this 
document, along with historical shipments from HPBA (www.hpba.org/Resources/Annual-Historical-Hearth-Shipments) and the February 2015 
NOPR National Impact Analysis, of which 39 percent are assumed to be 
decorative hearths, and a 15-year hearth lifetime which was used for 
all products in the February 2015 NOPR for hearth products (U.S. 
Department of Energy. Technical Support Document: Energy 
Conservation Programs for Consumer Products, Energy Conservation 
Standards for Hearth Products. Chapter 8: Life-Cycle-Cost Analysis. 
January 30, 2015. Available at: www.regulations.gov/document/EERE-2014-BT-STD-0036-0002.).
    \21\ The aggregate national energy use of outdoor heaters is 
based on energy use estimates developed in section V.B of this 
document, along with historical shipments from the February 2015 
NOPR National Impact Analysis, which assumed that ratio of patio 
heaters shipments to HPBA hearth shipments was 3 percent, and a 15-
year hearth lifetime which was used for all products in the February 
2015 NOPR for hearth products (U.S. Department of Energy. Technical 
Support Document: Energy Conservation Programs for Consumer 
Products, Energy Conservation Standards for Hearth Products. Chapter 
8: Life-Cycle-Cost Analysis. January 30, 2015. Available at: 
www.regulations.gov/document/EERE-2014-BT-STD-0036-0002.).
---------------------------------------------------------------------------

2. Average Annual Per-Household Energy Use
    DOE estimates that decorative hearths account for 93 percent of the 
MGP market and that outdoor heaters account for 7 percent. DOE 
calculated the weighted average per-household energy use of an MGP to 
be 4.1 MMbtu/yr (1,211 kWh/yr).\22\ Therefore, DOE estimates that the 
average annual per-household energy use for MGPs is likely to exceed 
100 kWh/yr, thereby satisfying the provisions of 42 U.S.C. 
6292(b)(1)(B).
---------------------------------------------------------------------------

    \22\ For more detail on the energy use calculations, please 
refer to the February 2022 NOPD, available at: www.regulations.gov/document/EERE-2021-BT-DET-0034-0001.
---------------------------------------------------------------------------

III. Final Determination

    Based on the foregoing discussion, DOE concludes that including 
MGPs, as defined in this final determination, as covered products is 
necessary and appropriate to carry out the purposes of EPCA, and the 
average annual per-household energy use by products of such type is 
likely to exceed 100 kWh/yr. Based on the information discussed in 
section II of this final determination, DOE is classifying MGPs as a 
covered product. This final determination does not establish test 
procedures or energy conservation standards for MGPs. DOE will address 
test procedures and energy conservation standards through its normal 
rulemaking process.

IV. Procedural Issues and Regulatory Review

A. Review Under Executive Orders 12866 and 13563

    Executive Order (``E.O.'') 12866, ``Regulatory Planning and 
Review,'' as supplemented and reaffirmed by E.O. 13563, ``Improving 
Regulation and Regulatory Review,'' 76 FR 3821 (Jan. 21, 2011), 
requires agencies, to the extent permitted by law, to (1) propose or 
adopt a regulation only upon a reasoned determination that its benefits 
justify its costs (recognizing that some benefits and costs are 
difficult to quantify); (2) tailor regulations to impose the least 
burden on society, consistent with obtaining regulatory objectives, 
taking into account, among other things, and to the extent practicable, 
the costs of cumulative regulations; (3) select, in choosing among 
alternative regulatory approaches, those approaches that maximize net 
benefits (including potential economic, environmental, public health 
and safety, and other advantages; distributive impacts; and equity); 
(4) to the extent feasible, specify performance objectives, rather than 
specifying the behavior or manner of compliance that regulated entities 
must adopt; and (5) identify and assess available alternatives to 
direct regulation, including providing economic incentives to encourage 
the desired behavior, such as user fees or marketable permits, or 
providing information upon which choices can be made by the public. DOE 
emphasizes as well that E.O. 13563 requires agencies to use the best 
available techniques to quantify anticipated present and future 
benefits and costs as accurately as possible. In its guidance, the 
Office of Information and Regulatory Affairs (``OIRA'') in the Office 
of Management and Budget (``OMB'') has emphasized that such techniques 
may include identifying changing future compliance costs that might 
result from technological innovation or anticipated behavioral changes. 
For the reasons stated in the preamble, this final regulatory action is 
consistent with these principles.
    Section 6(a) of E.O. 12866 also requires agencies to submit 
``significant regulatory actions'' to OIRA for review. OIRA has 
determined that this final regulatory action does not constitute a 
``significant regulatory action'' under section 3(f) of E.O. 12866. 
Accordingly, this action was not submitted to OIRA for review under 
E.O. 12866.

B. Review Under the Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires 
preparation of an initial regulatory flexibility analysis (``IRFA'') 
and a final regulatory flexibility analysis (``FRFA'') 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 (Aug. 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 
rulemaking process. 68 FR 7990. DOE

[[Page 54344]]

has made its procedures and policies available on the Office of the 
General Counsel's website (www.energy.gov/gc/office-general-counsel).
    DOE reviewed this final determination under the provisions of the 
Regulatory Flexibility Act and the policies and procedures published on 
February 19, 2003. This final determination does not establish test 
procedures or standards for MGPs. On the basis of the foregoing, DOE 
certifies that this final determination has no significant economic 
impact on a substantial number of small entities.

C. Review Under the Paperwork Reduction Act

    This final determination, which concludes that MGPs meet the 
criteria for a covered product for which the Secretary may consider 
prescribing energy conservation standards pursuant to 42 U.S.C. 6295(o) 
and (p), imposes no new information or record-keeping requirements. 
Accordingly, the OMB clearance is not required under the Paperwork 
Reduction Act. (44 U.S.C. 3501 et seq.)

D. Review Under the National Environmental Policy Act of 1969

    Pursuant to the National Environmental Policy Act of 1969 
(``NEPA''), DOE has analyzed this final determination in accordance 
with NEPA and DOE's NEPA implementing regulations (10 CFR part 1021). 
DOE has determined that this final determination qualifies for 
categorical exclusion under 10 CFR part 1021, subpart D, appendix A6, 
because it is strictly procedural and meets the requirements for 
application of a categorial exclusion. 10 CFR 1021.410. Therefore, DOE 
has determined that promulgation of this final determination is not a 
major Federal action significantly affecting the quality of the human 
environment within the meaning of NEPA, and does not require an 
Environmental Assessment or an Environmental Impact Statement.

E. Review Under Executive Order 13132

    E.O. 13132, ``Federalism,'' 64 FR 43255 (Aug. 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. This final determination does not establish 
energy conservation standards for MGPs. DOE has examined this final 
determination and concludes that it does not preempt State law or have 
substantial direct effect on the States, on the relationship between 
the Federal 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 final 
rule. Therefore, no further action is required by Executive Order 
13132.

F. Review Under Executive Order 12988

    With respect to 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 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 final determination meets the relevant standards of E.O. 12988.

G. Review Under the Unfunded Mandates Reform Act of 1995

    Title II of the Unfunded Mandates Reform Act of 1995 (``UMRA'') 
requires each Federal agency to assess the effects of Federal 
regulatory actions on State, local, and Tribal governments and the 
private sector. Public Law 104-4, sec. 201 (codified at 2 U.S.C. 1531). 
For a 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 ``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 
www.energy.gov/sites/prod/files/gcprod/documents/umra_97.pdf.
    DOE examined this final determination according to UMRA and its 
statement of policy and determined that the determination does not 
contain a Federal intergovernmental mandate, nor is it expected to 
require expenditures of $100 million or more in any one year by State, 
local, and Tribal governments, in the aggregate, or by the private 
sector. As a result, the analytical requirements of UMRA do not apply.

H. Review Under the Treasury and General Government Appropriations Act, 
1999

    Section 654 of the Treasury and General Government Appropriations 
Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family 
Policymaking Assessment for any rule that may affect family well-being. 
This final 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.

[[Page 54345]]

I. 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 final determination would not 
result in any takings that might require compensation under the Fifth 
Amendment to the U.S. Constitution.

J. 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). Pursuant to OMB Memorandum M-19-15, Improving 
Implementation of the Information Quality Act (April 24, 2019), DOE 
published updated guidelines which are available at: www.energy.gov/sites/prod/files/2019/12/f70/DOE%20Final%20Updated%20IQA%20Guidelines%20Dec%202019.pdf. DOE has 
reviewed this final determination under the OMB and DOE guidelines and 
has concluded that it is consistent with applicable policies in those 
guidelines.

K. Review Under Executive Order 13211

    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 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 Executive 
Order 12866, or any successor order; and (2) is likely to have a 
significant adverse effect on the supply, distribution, or use of 
energy, or (3) is designated by the Administrator of OIRA as a 
significant energy action. For any 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 final determination, which does not amend or establish energy 
conservation standards for MGPs, 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 such by the Administrator at OIRA. Accordingly, DOE has 
not prepared a Statement of Energy Effects.

L. Information Quality

    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.'' 70 FR 2664, 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 prepared a report describing that peer 
review.\23\ 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. 
Because available data, models, and technological understanding have 
changed since 2007, DOE has engaged with the National Academy of 
Sciences to review DOE's analytical methodologies to ascertain whether 
modifications are needed to improve the Department's analyses. DOE is 
in the process of evaluating the resulting report.\24\
