Energy Conservation Program: Energy Conservation Standards for
Metal Halide Lamp Fixtures
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Final determination.
-----------------------------------------------------------------------
SUMMARY: The Energy Policy and Conservation Act, as amended (``EPCA''),
prescribes energy conservation standards for various consumer products
and certain commercial and industrial equipment, including metal halide
lamp fixtures (``MHLFs''). EPCA also requires the U.S. Department of
Energy (``DOE'') to periodically determine whether more-stringent,
standards would be technologically feasible and economically justified,
and would result in significant energy savings. In this final
determination, DOE has determined that the energy conservation
standards for MHLFs do not need to be amended because they are not
economically justified.
DATES: The effective date of this final determination is November 24,
2021.

I. Synopsis of the Final Determination
Title III, Part B \1\ of the Energy Policy and Conservation Act, as
amended (``EPCA''),\2\ established the Energy Conservation Program for
Consumer Products Other Than Automobiles. (42 U.S.C. 6291-6309) These
products include metal halide lamp fixtures (``MHLFs''), the subject of
this final determination.
---------------------------------------------------------------------------
\1\ For editorial reasons, upon codification in the U.S. Code,
Part B was redesignated Part A.
\2\ All references to EPCA in this document refer to the statute
as amended through the Energy Act of 2020, Public Law 116-260 (Dec.
27, 2020).
---------------------------------------------------------------------------
EPCA established initial standards for MHLFs. (42 U.S.C.
6295(hh)(1)(A)) EPCA directed the U.S. Department of Energy (``DOE'')
to conduct a review of the statutory standards to determine whether
they should be amended, and a subsequent review to determine if the
standards then in effect should be amended. (42 U.S.C. 6295(hh)(2) and
(3)) DOE conducted the first review of MHLF energy conservation
standards and published a final rule amending standards on February 10,
2014. 79 FR 7746.\3\ DOE is issuing this final determination pursuant
to the EPCA requirement that DOE conduct a second review of MHLF energy
conservation standards. (42 U.S.C. 6295(hh)(3)(A))
---------------------------------------------------------------------------
\3\ DOE notes that because of the codification of the MHLF
provisions in 42 U.S.C. 6295, MHLF energy conservation standards and
the associated test procedures are subject to the requirements of
the consumer products provisions of Part B of Title III of EPCA.
However, because MHLFs are generally considered to be commercial
equipment, DOE established the requirements for MHLFs in 10 CFR part
431 (``Energy Efficiency Program for Certain Commercial and
Industrial Equipment'') for ease of reference. DOE notes that the
location of the provisions within the CFR does not affect either the
substance or applicable procedure for MHLFs. Based upon their
placement into 10 CFR part 431, MHLFs are referred to as
``equipment'' throughout this document, although covered by the
consumer product provisions of EPCA.
---------------------------------------------------------------------------
DOE analyzed MHLFs subject to standards specified in 10 CFR
431.326(c). DOE first analyzed the technological feasibility of more
efficient MHLFs. For those MHLFs for which DOE determined higher
standards to be technologically feasible, DOE estimated energy savings
that could result from potential energy conservation standards by
conducting a national impacts analysis (``NIA''). DOE evaluated whether
higher standards would be cost effective by conducting life-cycle cost
(``LCC'') and payback period (``PBP'') analyses, and estimated the net
present value (``NPV'') of the total costs and benefits experienced by
consumers.
Based on the results of these analyses, summarized in section V of
this document, DOE has determined that current standards for metal
halide lamp fixtures do not need to be amended because more stringent
standards would not be cost-effective (and by extension, would not be
economically justified).
II. Introduction
The following section briefly discusses the statutory authority
underlying this final determination, as well as some of the relevant
historical background related to the establishment of standards for
MHLFs.
A. Authority
EPCA authorizes DOE to regulate the energy efficiency of a number
of consumer products and certain industrial equipment. Title III, Part
B of EPCA established the Energy Conservation Program for Consumer
Products Other Than Automobiles. These products include MHLFs, the
subject of this document. (42 U.S.C. 6292(a)(19)) EPCA, as amended by
the Energy Independence and Security Act of 2007 (Pub. L. 110-140, EISA
2007), prescribed energy conservation standards for this equipment. (42
U.S.C. 6295(hh)(1)) EPCA directed DOE to conduct two rulemaking cycles
to determine whether to amend these standards. (42 U.S.C.
6295(hh)(2)(A) and (3)(A)) DOE published a final rule amending the
standards on February 10, 2014 (``2014 MHLF final rule''). 79 FR 7746.
Under 42 U.S.C. 6295(hh)(3)(A), the agency must conduct a second review
to determine whether current standards should be amended and publish a
final rule. This second MHLF standards rulemaking was initiated on July
1, 2019 through the publication of a request for information (``RFI'')
document in the Federal Register. 84 FR 31232 (``July 2019 RFI''). On
August 5, 2020, DOE published a notice of proposed determination
(``NOPD'') regarding energy conservation standards for MHLFs. 85 FR
47472 (``August 2020 NOPD'').
The energy conservation program under EPCA consists essentially of
four parts: (1) Testing, (2) labeling, (3) the establishment of Federal
energy conservation standards, and (4) certification and enforcement
procedures. Relevant provisions of EPCA specifically include
definitions (42 U.S.C. 6291), test procedures (42 U.S.C. 6293),
labeling provisions (42 U.S.C. 6294), energy conservation standards (42
U.S.C. 6295), and the authority to require information and reports from
manufacturers (42 U.S.C. 6296).
Federal energy efficiency requirements for covered products
established under EPCA generally supersede State laws and regulations
concerning energy conservation testing, labeling, and standards. (42
U.S.C. 6297(a)-(c)) DOE may, however, grant waivers of Federal
preemption in limited instances for particular State laws or
regulations, in accordance with the procedures and other provisions set
forth under EPCA. (See 42 U.S.C. 6297(d))
Subject to certain criteria and conditions, DOE is required to
develop test procedures to measure the energy efficiency, energy use,
or estimated annual operating cost of each covered product. (42 U.S.C.
6295(o)(3)(A) and 42 U.S.C. 6295(r)) Manufacturers of covered products
must use the prescribed DOE test procedure as the basis for certifying
to DOE that their products comply with the applicable energy
conservation standards adopted under EPCA and when making
representations to the public regarding the energy use or efficiency of
those products. (42 U.S.C. 6293(c) and 6295(s)) Similarly, DOE must use
these test procedures to determine whether the products comply with
standards adopted pursuant to EPCA. (42 U.S.C. 6295(s)) The DOE test
procedures for MHLF appear at 10 CFR 431.324.
In making a determination that the standards do not need to be
amended, DOE must evaluate under the criteria of 42 U.S.C. 6295(n)(2)
whether amended standards (1) will result in significant conservation
of energy, (2) are technologically feasible, and (3) are cost effective
as described under 42 U.S.C. 6295(o)(2)(B)(i)(II). (42 U.S.C.
6295(m)(1)(A) and 42 U.S.C. 6295(n)(2)) Under 42 U.S.C.
6295(o)(2)(B)(i)(II), an evaluation of cost effectiveness requires DOE
to consider savings in operating costs throughout the estimated average
life of the covered product in the type (or class) compared to any
increase in the price of, or in the initial charges for, or maintenance
expenses of, the covered products which are likely to result from the
imposition of the standard.
DOE is publishing this document to satisfy EPCA's requirement under
42 U.S.C. 6295(hh)(3)(A) to complete a second rulemaking for MHLFs and
to satisfy the 6-year lookback provision at 42 U.S.C. 6295(m)(1).
B. Background
1. Current Standards
In the 2014 MHLF final rule, DOE prescribed the current energy
conservation standards for MHLFs manufactured on or after February 10,
2017. 79 FR 7746. These standards are set forth in DOE's regulations at
10 CFR 431.326 and are specified in Table II.1.

2. History of Standards Rulemaking for MHLFs
As described in section II.A, EPCA, as amended by Public Law 110-
140, EISA 2007, prescribed energy conservation standards for MHLFs. (42
U.S.C. 6295(hh)(1)) EPCA directed DOE to conduct two rulemaking cycles
to determine whether to amend these standards. (42 U.S.C.
6295(hh)(2)(A) and (3)(A)) DOE completed the first of these rulemaking
cycles in 2014 by adopting amended performance standards for MHLFs
manufactured on or after February 10, 2017. 79 FR 7746. The current
energy conservation standards are located in 10 CFR part 431. See 10
CFR 431.326 (detailing the applicable energy conservation standards for
different classes of MHLFs). The currently applicable DOE test
procedures for MHLFs appear at 10 CFR 431.324. Under 42 U.S.C.
6295(hh)(3)(A), the agency is instructed to conduct a second review of
its energy conservation standards for MHLFs and publish a final rule to
determine whether to amend those standards. DOE initiated the second
MHLF standards rulemaking by publishing the July 2019 RFI and
subsequently, DOE published the August 2020 NOPD to support this
rulemaking requirement. 84 FR 31232; 85 FR 47472.
DOE received five comments in response to the August 2020 NOPD from
the interested parties listed in Table II.2

---------------------------------------------------------------------------
III. General Discussion
DOE developed this final determination after considering oral and
written comments, data, and information from interested parties that
represent a variety of interests.
A. Product Classes and Scope of Coverage
When evaluating and establishing energy conservation standards, DOE
divides covered products into product classes by the type of energy
used or by capacity or other performance-related features that justify
differing standards. In making a determination whether a performance-
related feature justifies a different standard, DOE must consider such
factors as the utility of the feature to the consumer and other factors
DOE determines are appropriate. (42 U.S.C. 6295(q)) This final
determination covers metal halide lamp fixtures defined as light
fixtures for general lighting application designed to be operated with
a metal halide lamp and a ballast
[[Page 58766]]
for a metal halide lamp. 42 U.S.C. 6291(64); 10 CFR 431.322. The scope
of coverage is discussed in further detail in section IV.B.1 of this
document.
B. Test Procedure
EPCA sets forth generally applicable criteria and procedures for
DOE's adoption and amendment of test procedures. (42 U.S.C. 6293)
Manufacturers of covered products must use these test procedures to
certify to DOE that their product complies with energy conservation
standards and to quantify the efficiency of their product. DOE's
current energy conservation standards for MHLFs are expressed in terms
of the efficiency of the ballast contained within the fixture. (10 CFR
431.326)
DOE established an active mode and standby mode power test method
for MHLFs in a final rule published on March 9, 2010. 75 FR 10950. The
current test procedure for MHLFs appears in 10 CFR 431.324 and
specifies the ballast efficiency calculation as lamp output power
divided by the ballast input power. DOE has since published an RFI to
initiate a data collection process to consider whether to amend DOE's
test procedure for MHLFs. 83 FR 24680 (May 30, 2018). On July 14, 2021,
DOE published a notice of proposed rulemaking to amend DOE's test
procedures for MHLFs (``July 2021 NOPR''). 86 FR 37069.
C. Technological Feasibility
1. General
In each energy conservation standards rulemaking, DOE conducts a
screening analysis based on information gathered on all current
technology options and prototype designs that could improve the
efficiency of the products or equipment that are the subject of the
rulemaking. As the first step in such an analysis, DOE develops a list
of technology options for consideration in consultation with
manufacturers, design engineers, and other interested parties. DOE then
determines which of those means for improving efficiency are
technologically feasible. Section 6(c)(1) of 10 CFR part 430, subpart
C, appendix A (the ``Process Rule''). DOE considers technologies
incorporated in commercially available products or in working
prototypes to be technologically feasible. Sections 6(c)(3)(i) and
7(b)(1) of the Process Rule.
After DOE has determined that particular technology options are
technologically feasible, it further evaluates each technology option
in light of the following additional screening criteria: (1)
Practicability to manufacture, install, and service; (2) adverse
impacts on product utility or availability; (3) adverse impacts on
health or safety and (4) unique-pathway proprietary technologies.
Sections 6(c)(3)(ii)-(v) and 7(b)(2)-(5) of the Process Rule.
Additionally, it is DOE policy not to include in its analysis any
proprietary technology that is a unique pathway to achieving a certain
efficiency level (``EL''). Section IV.B.5 of this document discusses
the results of the screening analysis for MHLFs, particularly the
designs DOE considered, those it screened out, and those that are the
basis for the standards considered in this rulemaking. For further
details on the screening analysis for this rulemaking, see chapter 4 of
the final determination technical support document (``TSD'').\5\
---------------------------------------------------------------------------
\5\ The final determination technical support document for this
notice can be found at www.regulations.gov/docket/EERE-;2017-BT-STD-
0016.
---------------------------------------------------------------------------
2. Maximum Technologically Feasible Levels
When DOE proposes to adopt an amended standard for a type or class
of covered product, it must determine the maximum improvement in energy
efficiency or maximum reduction in energy use that is technologically
feasible for such a product. (42 U.S.C. 6295(p)(1)) Accordingly, in the
engineering analysis, DOE determined the maximum technologically
feasible (``max-tech'') improvements in energy efficiency for MHLFs
using the design parameters for the most efficient products available
on the market or in working prototypes. The max-tech levels that DOE
determined for this rulemaking are described in section IV.C.4 and in
chapter 5 of the final determination TSD.
D. Energy Savings
1. Determination of Savings
For each trial standard level (``TSL''), DOE projected energy
savings from application of the TSL to MHLFs purchased in the 30-year
period that begins in the first full year of compliance with the
potential standards (2025-2054).\6\ The savings are measured over the
entire lifetime of MHLFs purchased in the 30-year analysis period. DOE
quantified the energy savings attributable to each TSL as the
difference in energy consumption between each standards case and the
no-new-standards case. The no-new-standards case represents a
projection of energy consumption that reflects how the market for a
product would likely evolve in the absence of energy conservation
standards.
---------------------------------------------------------------------------
\6\ DOE also presents a sensitivity analysis that considers
impacts for products shipped in a 9-year period.
---------------------------------------------------------------------------
DOE used its NIA spreadsheet models to estimate national energy
savings (``NES'') from potential amended standards for MHLFs. The NIA
spreadsheet model (described in section V.B.2 of this document)
calculates energy savings in terms of site energy, which is the energy
directly consumed by products at the locations where they are used. For
electricity, DOE reports national energy savings in terms of primary
energy savings, which is the savings in the energy that is used to
generate and transmit the site electricity. For natural gas, the
primary energy savings are considered to be equal to the site energy
savings. DOE also calculates NES in terms of full-fuel-cycle (``FFC'')
energy savings. The FFC metric includes the energy consumed in
extracting, processing, and transporting primary fuels (i.e., coal,
natural gas, petroleum fuels), and thus presents a more complete
picture of the impacts of energy conservation standards.\7\ DOE's
approach is based on the calculation of an FFC multiplier for each of
the energy types used by covered products or equipment. For more
information on FFC energy savings, see section IV.H.1 of this document.
---------------------------------------------------------------------------
\7\ The FFC metric is discussed in DOE's statement of policy and
notice of policy amendment. 76 FR 51282 (Aug. 18, 2011), as amended
at 77 FR 49701 (Aug. 17, 2012).
---------------------------------------------------------------------------
2. Significance of Savings
To adopt any new or amended standards for a covered MHLFs, DOE must
determine that such action would result in significant energy savings.
(42 U.S.C. 6295(o)(3)(B)) Although the term ``significant'' is not
defined in the EPCA, the U.S. Court of Appeals, for the District of
Columbia Circuit in Natural Resources Defense Council v. Herrington,
768 F.2d 1355, 1373 (D.C. Cir. 1985), opined that Congress intended
``significant'' energy savings in the context of EPCA to be savings
that were not ``genuinely trivial.''
Historically, DOE did not provide specific guidance or a numerical
threshold for determining what constitutes significant conservation of
energy. Instead, DOE determined on a case-by-case basis whether a
particular rulemaking would result in significant conservation of
energy. In a final rule published February 14, 2020, DOE adopted a
numerical threshold for significant conservation of energy. 85 FR 8626,
8670. Specifically, the threshold requires that an energy conservation
standard result in a 0.30
[[Page 58767]]
quad reduction in site energy use over a 30-year analysis period or a
10-percent reduction in site energy use over that same period. Id.
E. Economic Justification
1. Specific Criteria
EPCA provides seven factors to be evaluated in determining whether
a potential energy conservation standard is economically justified. (42
U.S.C. 6295(o)(2)(B)(i)(I)-(VII)) The following sections discuss how
DOE has addressed each of those seven factors in this final
determination.
a. Economic Impact on Manufacturers and Consumers
In determining the impacts of potential amended standards on
manufacturers, DOE conducts a manufacturer impact analysis (``MIA'').
DOE first uses an annual cash-flow approach to determine the
quantitative impacts. This step includes both a short-term assessment--
based on the cost and capital requirements during the period between
when a regulation is issued and when entities must comply with the
regulation--and a long-term assessment over a 30-year period. The
industry-wide impacts analyzed include (1) industry net present value,
which values the industry on the basis of expected future cash flows;
(2) cash flows by year; (3) changes in revenue and income; and (4)
other measures of impact, as appropriate. Second, DOE analyzes and
reports the impacts on different types of manufacturers, including
impacts on small manufacturers. Third, DOE considers the impact of
standards on domestic manufacturer employment and manufacturing
capacity, as well as the potential for standards to result in plant
closures and loss of capital investment. Finally, DOE takes into
account cumulative impacts of various DOE regulations and other
regulatory requirements on manufacturers.
For individual consumers, measures of economic impact include the
changes in LCC and PBP associated with new or amended standards. These
measures are discussed further in the following section. For consumers
in the aggregate, DOE also calculates the national net present value of
the consumer costs and benefits expected to result from particular
standards. DOE also evaluates the impacts of potential standards on
identifiable subgroups of consumers that may be affected
disproportionately by a standard.
As discussed further in section V.C of this document, DOE has
concluded amended standards for MHLFs would not be cost-effective (and
by extension, would not be economically justified) for the potential
standard levels evaluated based on the PBP and LCC analysis. Therefore,
DOE did not conduct an MIA analysis or LCC subgroup analysis for this
final determination.
b. Savings in Operating Costs Compared To Increase in Price (LCC and
PBP)
EPCA requires DOE to consider the savings in operating costs
throughout the estimated average life of the covered product in the
type (or class) compared to any increase in the price of, or in the
initial charges for, or maintenance expenses of, the covered product
that are likely to result from a standard. (42 U.S.C.
6295(o)(2)(B)(i)(II)) DOE conducts this comparison in its LCC and PBP
analysis.
The LCC is the sum of the purchase price of a product (including
its installation) and the operating cost (including energy,
maintenance, and repair expenditures) discounted over the lifetime of
the product. The LCC analysis requires a variety of inputs, such as
product prices, product energy consumption, energy prices, maintenance
and repair costs, product lifetime, and discount rates appropriate for
consumers. To account for uncertainty and variability in specific
inputs, such as product lifetime and discount rate, DOE uses a
distribution of values, with probabilities attached to each value.
The PBP is the estimated amount of time (in years) it takes
consumers to recover the increased purchase cost (including
installation) of a more-efficient product through lower operating
costs. DOE calculates the PBP by dividing the change in purchase cost
due to a more-stringent standard by the change in annual operating cost
for the year that standards are assumed to take effect.
For its LCC and PBP analysis, DOE assumes that consumers will
purchase the covered products in the first year of compliance with new
or amended standards. The LCC savings for the considered efficiency
levels are calculated relative to the case that reflects projected
market trends in the absence of new or amended standards. DOE's LCC and
PBP analysis is discussed in further detail in section IV.F.
c. Energy Savings
Although significant conservation of energy is a separate statutory
requirement for adopting an energy conservation standard, EPCA requires
DOE, in determining the economic justification of a standard, to
consider the total projected energy savings that are expected to result
directly from the standard. (42 U.S.C. 6295(o)(2)(B)(i)(III)) As
discussed in section IV.H, DOE uses the NIA spreadsheet models to
project national energy savings.
d. Lessening of Utility or Performance of Products
In establishing product classes, and in evaluating design options
and the impact of potential standard levels, DOE evaluates potential
standards that would not lessen the utility or performance of the
considered products. (42 U.S.C. 6295(o)(2)(B)(i)(IV)) Based on data
available to DOE, the standards analyzed in this document would not
reduce the utility or performance of the products under consideration
in this rulemaking. DOE also determined that analyzed standards would
not result in the unavailability performance characteristics of
products under consideration that are generally available at the time
of this rulemaking. (42 U.S.C. 6295(o)(4))
e. Impact of Any Lessening of Competition
EPCA directs DOE to consider the impact of any lessening of
competition, as determined in writing by the Attorney General, that is
likely to result from a standard. (42 U.S.C. 6295(o)(2)(B)(i)(V)) It
also directs the Attorney General to determine the impact, if any, of
any lessening of competition likely to result from a standard and to
transmit such determination to the Secretary within 60 days of the
publication of a proposed rule, together with an analysis of the nature
and extent of the impact. (42 U.S.C. 6295(o)(2)(B)(ii)) Because DOE is
not amending standards for MHLFs, DOE did not transmit a copy of its
proposed determination to the Attorney General.
f. Need for National Energy Conservation
DOE also considers the need for national energy and water
conservation in determining whether a new or amended standard is
economically justified. (42 U.S.C. 6295(o)(2)(B)(i)(VI)) The energy
savings from the adopted standards are likely to provide improvements
to the security and reliability of the Nation's energy system.
Reductions in the demand for electricity also may result in reduced
costs for maintaining the reliability of the Nation's electricity
system.
DOE maintains that environmental and public health benefits
associated with the more efficient use of energy are important to take
into account when
[[Page 58768]]
considering the need for national energy conservation. Because DOE has
concluded that amended standards for MHLFs would not be economically
justified, DOE did not conduct a utility impact analysis or emissions
analysis for this final determination.
g. Other Factors
In determining whether an energy conservation standard is
economically justified, DOE may consider any other factors that the
Secretary deems to be relevant. (42 U.S.C. 6295(o)(2)(B)(i)(VII)) To
the extent DOE identifies any relevant information regarding economic
justification that does not fit into the other categories described
previously, DOE could consider such information under ``other
factors.''
2. Rebuttable Presumption
As set forth in 42 U.S.C. 6295(o)(2)(B)(iii), EPCA creates a
rebuttable presumption that an energy conservation standard is
economically justified if the additional cost to the consumer of a
product that meets the standard is less than three times the value of
the first year's energy savings resulting from the standard, as
calculated under the applicable DOE test procedure. DOE's LCC and PBP
analyses generate values used to calculate the effect potential amended
energy conservation standards would have on the payback period for
consumers. These analyses include, but are not limited to, the 3-year
payback period contemplated under the rebuttable-presumption test. In
addition, DOE routinely conducts an economic analysis that considers
the full range of impacts to consumers, manufacturers, the Nation, and
the environment, as required under 42 U.S.C. 6295(o)(2)(B)(i). The
results of this analysis serve as the basis for DOE's evaluation of the
economic justification for a potential standard level (thereby
supporting or rebutting the results of any preliminary determination of
economic justification). The rebuttable presumption payback calculation
is discussed in section IV.F.9 of this final determination.
IV. Methodology and Discussion of Related Comments
This section addresses the analyses DOE has performed for this
rulemaking with regards to MHLFs. Separate subsections address each
component of DOE's analyses and respond to comments received.
DOE used several analytical tools to estimate the impact of the
standards considered in this document. The first tool is a spreadsheet
that calculates the LCC savings and PBP of potential amended or new
energy conservation standards. The national impacts analysis uses a
second spreadsheet set that provides shipments projections and
calculates national energy savings and net present value of total
consumer costs and savings expected to result from potential energy
conservation standards. These spreadsheet tools are available on the
DOE website for this rulemaking: www1.eere.energy.gov/buildings/appliance_standards/standards.aspx?productid=14.
A. Overall
DOE received several comments regarding its tentative conclusion in
the August 2020 NOPD to not amend standards for MHLFs. NEMA agreed with
DOE's proposed determination stating that the industry would not be
able to recover investments in new standards for MHLFs based on the
continued decline of shipments (80 percent reduction in MHLF shipments
from 2008 through 2018). (NEMA, No. 12 at p. 2) Additionally, NEMA
stated that due to the rapidly declining market, attaining significant
energy savings in a reasonable time did not seem possible. (NEMA, No.
12 at p. 4) Signify agreed with DOE's proposed determination that
standards for MHLFs do not need to be amended. However, Signify stated
that it supported standards for metal halide (``MH'') ballasts designed
to operate lamps with wattages between >1,000 W and <=2,000 W as such
standards would incentivize a rational use of energy for high power MH
lamp luminaire applications. (Signify, No. 13 at pp. 2, 12)
A private citizen also agreed with DOE's proposed determination,
stating that shipments have declined over 90 percent in the last 10-15
years and will continue to do so. The citizen also stated that MH lamps
are not used in new buildings or new outdoor lighting. The citizen
recommended DOE not have to repeat this analysis in three years unless
shipment increased by at least some ``X'' percent during that time.
(Anonymous, No. 10, p. 1)
When expressing concerns regarding max-tech levels proposed in the
August 2020 NOPD, NEMA recommended DOE publish a supplemental notice to
the August 2020 NOPD rather than a final rule to avoid risking future
challenges. (NEMA, No. 12 at p. 3) (See section IV.C.4 for the
discussion of NEMA's comment regarding max-tech levels.) Additionally,
in response to a separate rule requesting comment regarding rulemaking
prioritizations, NEMA stated that if DOE were to quickly verify the
decline in sale and no notable energy saving opportunities for MHLFs, a
negative determination could be made and allow DOE resources to be
applied elsewhere with more significant energy savings. (NEMA, No. 15
\8\ at p. 4)
---------------------------------------------------------------------------
\8\ This comment was received in response to a Request for
Comment on the prioritization of rulemakings pursuant to the
Department's updated and modernized rulemaking methodology titled,
``Procedures, Interpretations, and Policies for Consideration of New
or Revised Energy Conservation Standards and Test Procedures for
Consumer Products and Commercial/Industrial Equipment'' (Process
Rule), Docket ID: EERE-2020-BT-STD-004, available at
www.regulations.gov/document/EERE-2020-BT-STD-0004-0001.
---------------------------------------------------------------------------
The CA IOUs stated that DOE's analysis was incomplete and that it
should consider revising its shipments and cost data. The CA IOUs urged
DOE to refrain from issuing a final determination until the adjustments
to the data have been made and shared with stakeholders. (CA IOUs, No.
14, pp. 2-3) (See section IV.C.6 for discussion of the CA IOU's
comments on prices and section IV.G for shipments.)
Concerns raised in comments received on the August 2020 NOPD are
addressed in this document and do not result in major changes to the
analysis. Hence, DOE is not publishing supplemental notice to the
August 2020 NOPD. In this final determination DOE is not amending
current standards for MHLFs because more stringent standards would not
be cost-effective (and by extension, would not be economically
justified). DOE made this determination by conducting an analysis of
covered MHLFs including those containing MH ballasts designed to
operate lamps with wattages between >1,000 W and <=2,000 W. As noted in
section II.A, DOE is completing this final determination as directed by
EPCA to conduct a secondary rulemaking for MHLFs.
B. Market and Technology Assessment
DOE conducted a market and technology assessment in support of this
final determination. DOE develops information in the market and
technology assessment that provides an overall picture of the market
for the products concerned, including the purpose of the products, the
industry structure, manufacturers, market characteristics, and
technologies used in the products. This activity includes both
quantitative and qualitative assessments, based primarily on publicly-
available information. The subjects addressed in the market and
technology assessment for this rulemaking include (1) a determination
of the scope of the rulemaking and product classes, (2) manufacturers
and
[[Page 58769]]
industry structure, (3) existing efficiency programs, (4) shipments
information, (5) market and industry trends, and (6) technologies or
design options that could improve the energy efficiency of MHLFs. The
key findings of DOE's market assessment are summarized in the following
sections. See chapter 3 of the final determination TSD for further
discussion of the market and technology assessment.
1. Scope of Coverage
MHLF is defined as a light fixture for general lighting application
designed to be operated with a metal halide lamp and a ballast for a
metal halide lamp. 42 U.S.C. 6291(64); 10 CFR 431.322. Any equipment
meeting the definition of MHLF is included in DOE's scope of coverage,
though all equipment within the scope of coverage may not be subject to
standards.
Signify stated that it appreciated the clarification in the August
2020 NOPD that DOE has does not have authority to evaluate amended
standards for metal halide ballasts sold outside of MHLFs as this is a
frequent question asked by its customers. (Signify, No. 13 at p. 13)
2. Test Procedure
The current test procedure for MHLFs appears in 10 CFR 431.324 and
specifies the ballast efficiency calculation as lamp output power
divided by the ballast input power. With regards to the max-tech levels
in the August 2020 NOPD, Signify questioned the certification data for
any ballast operating a MH lamp at a frequency higher than 400 hertz
(``Hz''). Signify stated that the current DOE test procedure references
ANSI C82.6-2015(R2020) \9\ which excludes from scope ballasts that
operate at higher than 400 Hz for high-intensity discharge (``HID'')
lamps. Therefore, energy efficiencies for ballasts operating at
frequencies higher than 400 Hz may have been reported to DOE in error.
Signify explained that a test setup specific to high-frequency ballasts
is needed as these ballasts are more susceptible to high-frequency
parasitic elements among wires and means of interconnections and
require the appropriate power supply impedance to prevent the injection
of high-frequency voltage components. Hence, Signify suggested that DOE
not adopt the max-tech efficiency levels for electronic ballasts until
the test method is amended to include accurate measurements of high-
frequency electronic MH lamp ballasts. (Signify, No. 13 at pp. 9-10)
---------------------------------------------------------------------------
\9\ American National Standards Institute. American National
Standard for Lamp ballasts--Ballasts for High-Intensity Discharge
Lamps--Methods of Measurement. Approved March 20, 2020.
---------------------------------------------------------------------------
The 2015 version and the 2015(R2020) \10\ version of ANSI C82.6 do
state that their procedures apply to low-frequency ballasts (i.e.,
ballasts that operate at less than 400 Hz). DOE's current test
procedure for MHLFs references the 2005 version of ANSI C82.6 which
does not explicitly exclude certain ballasts. In 2017, ANSI published
ANSI C82.17-2017, ``High Frequency (HF) Electronic Ballasts for Metal
Halide Lamps,'' which addressed HF electronic metal halide ballasts
with sinusoidal lamp operating current frequencies above 40 kilohertz.
ANSI C82.17-2017 also states in section 5.1 that ``all measurements
necessary to determine compliance with the ballast performance
requirements of this standard shall be made in accordance with ANSI
C82.6.'' In the July 2021 NOPR DOE tentatively determined that based on
its initial review, the specifications, and instructions in ANSI C82.6
cover the necessary methodology, while being general enough to be used
as a guide for taking measurements for HF electronic ballasts. 86 FR
37069, 37078.
---------------------------------------------------------------------------
\10\ There are no differences between the 2015(R2020) and 2015
versions of ANSI C82.6. The 2015(R2020) version is reaffirmation of
the 2015 version.
---------------------------------------------------------------------------
3. Equipment Classes
When evaluating and establishing energy conservation standards, DOE
may divide covered products into product classes by the type of energy
used, or by capacity or other performance-related features that justify
a different standard. (42 U.S.C. 6295(q)) In making a determination
whether capacity or another performance-related feature justifies a
different standard, DOE must consider such factors as the utility of
the feature to the consumer and other factors DOE deems appropriate.
(Id.)
In the August 2020 NOPD, DOE reviewed metal halide lamp fixtures
and the ballasts contained within them to identify performance-related
features that could potentially justify a separate equipment class. DOE
proposed to maintain the current equipment classes which are based on
input voltage, rated lamp wattage, and designation for indoor versus
outdoor application. 85 FR 47472, 47482-47483. DOE received no comments
on this topic and maintains the current equipment classes in this final
determination.
The equipment classes considered in this final determination are
shown in Table IV.1.

rated only for 150 W lamps; rated for use in wet locations, as
specified by the NFPA 70-2002, section 410.4(A);); and containing a
ballast that is rated to operate at ambient air temperatures above 50
[deg]C, as specified by UL 1029-2007.
** Excludes 150 W MHLFs initially exempted by EISA 2007, which are MHLFs

ballast that is rated to operate at ambient air temperatures above 50
[deg]C, as specified by UL 1029-2007.
[Dagger] Input voltage for testing would be specified by the test
procedures. Ballasts rated to operate lamps less than 150 W would be
tested at 120 V, and ballasts rated to operate lamps >=150 W would be
tested at 277 V. Ballasts not designed to operate at either of these
voltages would be tested at the highest voltage the ballast is
designed to operate.
4. Technology Options
In the technology assessment, DOE identifies technology options
that would be expected to improve the efficiency of MHLFs, as measured
by the DOE test procedure. The energy conservation standard
requirements and DOE test procedure for MHLFs are based on the
efficiency of the MH ballast contained within the fixture. Hence DOE
identified technology options that would improve the efficiency of MH
ballasts. To develop a list of technology options, DOE reviewed
manufacturer catalogs, recent trade publications and technical
journals, and consulted with technical experts.
A complete list of technology options DOE considered in the August
2020 NOPD appears in Table IV.2. 85 FR 47472, 47484. DOE did not
receive comments on technology options considered in the August 2020
NOPD and therefore continues to consider them in this final
determination. See chapter 3 of final determination TSD for further
information.

------------------------------------------------------------------------
5. Screening Analysis
DOE uses the following five screening criteria to determine which
technology options are suitable for further consideration in an energy
conservation standards rulemaking:
(1) Technological feasibility. Technologies that are not
incorporated in commercial products or in working prototypes will not
be considered further.
(2) Practicability to manufacture, install, and service. If it is
determined that mass production and reliable installation and servicing
of a technology in commercial products could not be achieved on the
scale necessary to serve the relevant market at the time of the
projected compliance date of the standard, then that technology will
not be considered further.
(3) Impacts on product utility or product availability. If it is
determined that a technology would have significant adverse impact on
the utility of the product to significant subgroups of consumers or
would result in the unavailability of any covered product type with
performance characteristics (including reliability), features, sizes,
capacities, and volumes that are substantially the same as products
generally available in the United States at the time, it will not be
considered further.
(4) Adverse impacts on health or safety. If it is determined that a
technology would have significant adverse impacts on health or safety,
it will not be considered further.
(5) Unique-Pathway Proprietary Technologies. If a design option
utilizes proprietary technology that represents a unique pathway to
achieving a given efficiency level, that technology will not be
considered further due to the potential for monopolistic concerns.
[[Page 58771]]
Sections 6(c)(3) and 7(b) of the Process Rule.
In sum, if DOE determines that a technology, or a combination of
technologies, fails to meet one or more of the listed five criteria, it
will be excluded from further consideration in the engineering
analysis. The reasons for eliminating any technology are discussed in
the following sections.
DOE evaluated of each the technology options against the screening
analysis criteria and determined whether it should be excluded
(``screened out'') based on the screening criteria. DOE did not receive
comments on technology options screened out in the August 2020 NOPD and
therefore screened out the same technology options in this final
determination.
a. Screened-Out Technologies
For magnetic ballasts, DOE screened out the technology option of
using laminated sheets of amorphous steel. DOE determined that using
amorphous steel could have adverse impacts on consumer utility because
increasing the size and weight of the ballast may limit the places a
customer could use the ballast. 85 FR 47472, 47484.
b. Remaining Technologies
DOE concludes that all of the other identified technologies listed
in section IV.B.4 met all five screening criteria to be examined
further as design options in DOE's final determination. In summary, DOE
did not screen out the following technology options:
[squ] Magnetic Ballasts
[cir] Improved Core Steel
[cir] Copper Wiring
[cir] Improved Steel Laminations
[cir] Improved Windings
[cir] Electronic Ballast
[squ] Electronic Ballasts
[cir] Improved Components
[cir] Improved Circuit Design
85 FR 47472, 47485.
DOE determined that these technology options are technologically
feasible because they are being used or have previously been used in
commercially-available products or working prototypes. DOE also finds
that all of the remaining technology options meet the other screening
criteria (i.e., practicable to manufacture, install, and service; do
not result in adverse impacts on consumer utility, product
availability, health, or safety; and do not utilize proprietary
technology). For additional details, see chapter 4 of the final
determination TSD.
C. Engineering Analysis
In the engineering analysis, DOE develops cost-efficiency
relationships characterizing the incremental costs of achieving
increased ballast efficiency. This relationship serves as the basis for
cost-benefit calculations for individual consumers and the nation. The
methodology for the engineering analysis consists of the following
steps: (1) Selecting representative equipment classes; (2) selecting
baseline metal halide ballasts; (3) identifying more efficient
substitutes; (4) developing efficiency levels; and (5) scaling
efficiency levels to non-representative equipment classes. The details
of the engineering analysis are discussed in chapter 5 of the final
determination TSD.
1. Representative Equipment Classes
DOE selects certain equipment classes as ``representative'' to
focus its analysis. DOE chooses equipment classes as representative
primarily because of their high market volumes and/or unique
characteristics. DOE established 24 equipment classes based on input
voltage, rated lamp wattage, and indoor/outdoor designation. DOE did
not directly analyze the equipment classes containing only fixtures
with ballasts tested at 480 V due to low shipment volumes. DOE selected
all other equipment classes as representative, resulting in a total of
12 representative classes covering the full range of lamp wattages, as
well as indoor and outdoor designations. 76 FR 47472, 47485-47486.
In the August 2020 NOPD DOE directly analyzed the equipment classes
shown in gray in Table IV.3 of this document. 76 FR 47472, 47485-47486.
DOE did not receive any comments on the representative product classes
presented in the August 2020 NOPD. Therefore, DOE continues to analyze
the representative product classes shown in gray in Table IV.3 in this
final determination.
BILLING CODE 6450-01-P
[[Page 58772]]
[GRAPHIC] [TIFF OMITTED] TR25OC21.007
BILLING CODE 6450-01-C
Metal halide lamp fixtures are designed to be operated with lamps
of certain rated lamp wattages and contain ballasts that can operate
lamps at these wattages. To further focus the analysis, DOE selected a
representative rated wattage in each equipment class. Each
representative wattage was the most common wattage within each
equipment class. In the August 2020 NOPD DOE found that common wattages
within each equipment class were the same for outdoor and indoor
fixtures. Specifically, DOE selected 70 W, 150 W, 250 W, 400 W, 1,000 W
and 1,500 W as representative wattages to analyze. 85 FR 47472, 47486-
47487.
DOE did not receive any comments on the representative wattages
presented in the August 2020 NOPD and therefore continues to analyze
the same representative wattages in this final determination. The
representative wattages for each equipment class are summarized in
Table IV.4 of this document. See chapter 5 of this final determination
TSD for further details.

* Includes 150 W fixtures initially exempted by EISA 2007, which are
fixtures rated only for 150 watt lamps; rated for use in wet
locations, as specified by the NFPA 70-2002, section 410.4(A); and
containing a ballast that is rated to operate at ambient air
temperatures above 50 [deg]C, as specified by UL 1029-2007.
[[Page 58773]]
** Excludes 150 W fixtures initially exempted by EISA 2007, which are
fixtures rated only for 150 watt lamps; rated for use in wet

containing a ballast that is rated to operate at ambient air
temperatures above 50 [deg]C, as specified by UL 1029-2007.
2. Baseline Ballasts
For each representative equipment class, DOE selected baseline
ballasts to serve as reference points against which DOE measured
changes from potential amended energy conservation standards.
Typically, the baseline ballast is the most common, least efficient
ballast that meets existing energy conservation standards.
In the August 2020 NOPD, DOE selected as baselines the least
efficient ballasts meeting standards that have common attributes for
ballasts in each equipment class such as circuit type, input voltage
and ballast type. DOE used the efficiency values of ballasts contained
in MHLFs certified in DOE's compliance certification database to
identify baseline ballasts for all equipment classes except the >1,000
W and <=2,000 W equipment class. Because fixtures in this equipment
class are not currently subject to standards, and therefore do not have
DOE certification data, DOE determined baseline ballast efficiency
values by using catalog data.
In the August 2020 NOPD, DOE directly analyzed the baseline
ballasts shown in Table IV.5 of this document. 85 FR 47472, 47487. DOE
did not receive any comments on the baseline ballasts identified in the
August 2020 NOPD and therefore continues to analyze the same baseline
ballasts in this final determination. See chapter 5 of this final
determination TSD for further details.

specified by UL 1029-2007.
3. More-Efficient Ballasts
In the August 2020 NOPD, DOE selected more-efficient ballasts as
replacements for each of the baseline ballasts by considering
commercially available ballasts. DOE selected more-efficient ballasts
with similar attributes as the baseline ballast when possible (e.g.,
circuit type, input voltage). As with the baseline ballasts, DOE used
the ballast efficiency values from the compliance certification
database to identify more efficient ballasts for all equipment classes
except for the >1,000 W and <=2,000 W equipment class which does not
have certification data available. For this equipment class, DOE
determined ballast efficiency values by first gathering and analyzing
catalog data. DOE then tested the ballasts to verify the ballast
efficiency reported by the manufacturer. For instances where the
catalog data did not align with the tested data, DOE selected more-
efficient ballasts based on the tested ballast efficiency. 85 FR 47472,
47487.
DOE did not receive any comments on the more-efficient ballasts
selected in the August 2020 NOPD and therefore continues to analyze the
same more-efficient ballasts in this final determination. In the August
2020 NOPD and chapter 5 of the NOPD TSD there were typos in some
characteristics specified for the more-efficient ballasts. The system
input power for the 70 W EL 2 representative unit stated as 0.814 in
the August 2020 NOPD and TSD and should have been specified as 81.4.
The system input power for the 250 W EL 1 representative unit stated as
276.5 in the August 2020 NOPD and TSD should have been 278.7. The
system input power for the 1,500 W EL 1 representative unit stated as
1,000 W, Pulse start, with a system input power of 1063.8 and ballast
efficiency of 0.94 in the August 2020 NOPD should have been a 1,500 W,
Probe start with system input of 1,600.9 and ballast efficiency of
0.937. These typos have been corrected in this document and chapter 5
of this final determination TSD. The characteristics of the more-
efficient representative units are summarized in Tables IV.6 through
IV.11 of this document. See chapter 5 of this final determination TSD
for further details.

4. Efficiency Levels
Based on the more-efficient ballasts selected for analysis, DOE
develops ELs for the representative equipment classes. DOE defines a
``max-tech'' efficiency level to represent the maximum possible
efficiency for a given product.
In the August 2020 NOPD DOE identified one magnetic EL in every
equipment class. The more-efficient magnetic EL represents a magnetic
ballast with a higher grade of steel compared to the baseline. DOE
identified a second EL (an electronic EL) for the >=150 W and <=250 W
and >250 W and <=500 W equipment classes. The standard electronic level
represents a ballast with standard electronic circuitry. DOE identified
a third EL (a more efficient electronic EL) in the >=50 W and <= 100 W
and >100 W and <150 W equipment classes. The more-efficient electronic
EL represents an electronic ballast with an improved circuit design
and/or more efficient components compared to the standard electronic
level. 85 FR 47472, 47487-47488.
DOE received several comments regarding the ELs proposed in the
August 2020 NOPD.
NEMA stated that DOE had not adequately explained the basis for
changing efficiency equations from the previous rulemaking. NEMA stated
that the modifications to the equations resulted in efficiency levels
inconsistent with DOE's intent. (NEMA, No. 12 at p. 2)
Current MHLF standards specify power-law equations for ballasts
operating lamps with rated wattages >=50 W and <=500 W and linear
equations for ballasts operating lamps with rated wattages >500 W and
<=1,000 W. Using MHLF efficiency data DOE determined that the current
equation forms remain valid. DOE modified only the coefficients and
exponents of the equations to best fit the MHLF efficiency data while
forming one continuous equation across equipment classes, where
possible. In this final determination, DOE maintains the equations put
forth in the August 2020 NOPD but makes minor adjustments, detailed in
the paragraphs below, to the proposed coefficients and exponents to
allow the most efficient products to meet max tech.
For the >=50 W and <=100 W equipment class tested at voltages other
than 480 V NEMA stated that EL 1 and EL 2 appeared feasible but would
require stretching the technological capability. NEMA stated that EL 3
for this equipment class may be achievable but would require physical
size changes that would render the product incompatible with the
existing fixture form factor. NEMA stated DOE should modify EL 1 and EL
2 according to current product capabilities and eliminate EL 3 for this
equipment class. (NEMA, No. 12 at p. 2) Signify stated that for the
ballasts in the >=50 W and <=100 W tested at voltages other than 480 V
equipment class the minimum efficiency requirement would increase by
0.10 at the proposed EL 3. This would require a ballast to operate a 70
W lamp at an efficiency higher than 0.90. Signify stated that a 0.90
ballast efficiency requirement would be higher than DOE's current
efficiency requirement for an external power supply, a device that is
simpler with less stages than an electronic ballast. Signify stated it
is difficult to explain how a ballast with the same power as an
external power supply would have a higher efficiency and still preserve
the necessary form factor. (Signify, No. 13 at pp. 8-10)
DOE identified ballasts in DOE's compliance certification database
that are in the >=50 W and <=100 W tested at voltages other than 480 V
equipment class and meet the proposed EL 3 for this equipment class.
These ballasts included models that operate 70 W lamps. Because there
are products that meet the max tech level, DOE is not adjusting ELs
proposed for this equipment class in this final determination.
For the >100 W and <150 W equipment classes for all voltages, NEMA
stated that EL 3 was unrealistically high for ballasts tested at 480 V
(88.9 percent versus the current 82 percent requirement) and as high as
90.9 percent for ballasts tested at voltages other than 480 V. NEMA
stated that based on its review of DOE's
[[Page 58775]]
compliance certification database only four products \11\ between 140 W
and 150 W currently met this level of efficiency. (NEMA, No. 12 at p.
2)
---------------------------------------------------------------------------
\11\ It was unclear from the comment whether NEMA was referring
to four products tested at 480 V or at voltages other than 480 V.
---------------------------------------------------------------------------
DOE identified ballasts in DOE's compliance certification database
that are in the >100 W and <150 W tested at voltages other than 480 V
equipment class and meet the proposed EL 3 for this equipment class.
Because there are products that meet the max tech level, DOE is not
adjusting ELs proposed for this equipment class in this final
determination. However, DOE is adjusting the ELs for the >100 W and
<150 W tested at 480 V equipment class (see section IV.C.5 for further
details) in this final determination.
NEMA stated that for the >=150 W and <=250 W equipment classes for
all voltages the proposed ELs for 150 to 200 W are close to those in
the previous rulemaking and therefore, already screened for
technological feasibility. (NEMA, No. 12 at p. 3) DOE ensured that all
ELs analyzed represent commercially available products and therefore,
are technologically feasible.
NEMA stated that the proposed EL 1 for ballasts operating lamps
between 200 W to 250 W appears slightly lower than the current
standards, which is not permissible and should be amended. (NEMA, No.
12 at p. 3)
DOE reviewed all ELs developed for this analysis to ensure that
they are equal to or more stringent to the existing minimum MHLF
ballast efficiency standard (i.e., that backsliding is not occurring).
For EL 1 for the >=150 W and <=250 W equipment class tested at voltages
other than 480 V, DOE is modifying the equation to ensure no
backsliding occurs across the entire wattage range. Specifically, in
this final determination DOE is modifying the exponent in the equation
from 1/(1+0.5017*P[supcaret](-0.26)) to 1/(1+0.507*P[supcaret](-
0.263)).
NEMA also stated that for ballasts operating lamps between 200 W
and 250 W, EL 2 appears technologically feasible. Additionally, NEMA
stated that based on its review of DOE's compliance certification
database only two products operating lamps between 200 W and 250 W,
both from a single manufacturer, met EL 3, which means EL 3 is arguably
infeasible. (NEMA, No. 12 at p. 3)
DOE identified ballasts in DOE's compliance certification database
that are in >=150 W and <=250 W tested at voltages other than 480 V
equipment class and meet the proposed EL 3 for this equipment class.
These ballasts are from multiple manufacturers. Because there are
products that meet the max tech level, DOE is not adjusting ELs (aside
from EL 1 to prevent backsliding) proposed for this equipment class in
this final determination. DOE addresses ELs for the >=150 W and <=250 W
tested at 480 V equipment class in section IV.C.5.
NEMA stated that the proposed EL 1 for ballasts operating lamps
between 200 W and 500 W for all voltages appears slightly lower than
the current standards, which is not permissible. (NEMA, No. 12 at p. 3)
For the >250 W and <=500 W equipment class tested at voltages other
than 480 V, NEMA stated that DOE's compliance certification database
does not have products meeting EL 2 and EL 3 for higher wattages
indicating that they are technologically infeasible. (NEMA, No. 12 at
p. 3)
DOE identified ballasts in DOE's compliance certification database
that are in the >250 W and <=500 W equipment class tested at voltages
other than 480 V equipment class and meet the proposed EL 3 for this
equipment class. These ballasts operate 250 W and 400 W lamps. Because
there are products that meet the max tech level, DOE is not adjusting
ELs proposed for this equipment class in this final determination. For
EL 1 for the >=250 W and <=500 W equipment class tested at voltages
other than 480 V, DOE is modifying the equation to ensure no
backsliding occurs across the entire wattage range. Specifically, in
this final determination DOE is modifying the exponent in the equation
from 1/(1 + 0.5017*P[supcaret](-0.26)) to 1/(1 + 0.507*P[supcaret](-
0.263)).
For the >500 W and <=1,000 W equipment class, NEMA stated that the
97 percent efficiency requirement at EL 1 would eliminate nearly all
currently certified products making it technologically infeasible. NEMA
stated that per DOE's compliance certification database the few
ballasts that reach the 93 percent efficiency level would not be able
to meet 97 percent efficiency because they operate 1,000 W lamps.
(NEMA, No. 12 at p. 3)
The max tech level for the >500 W and <=1,000 W equipment class
tested at voltages other than 480V is based on a 1,000 W representative
unit with an efficiency of 0.94. DOE identified ballasts in DOE's
compliance certification database that are in the >500 W and <=1,000 W
tested at voltages other than 480 V equipment class and meet the
proposed EL 1 (max tech) for this equipment class. Because there are
products that meet the max tech level, DOE is not adjusting ELs
proposed for this equipment class in this final determination. DOE
addresses ELs for the >500 W and <=1,000 W tested at 480 V equipment
class in section IV.C.5.
For the >1,000 W and <=2,000 W equipment class, Signify stated DOE
should set a standard but disagreed with DOE's proposed EL for this
equipment class. Signify noted that, per some ballast catalogs, DOE
found that ballasts operating 2,000 W lamps are less efficient than
those operating 1,000 W. Signify stated that ballast efficiency
decreasing as wattage increases is contradictory to ballasts in other
equipment classes and it had found no documented scientific or
engineering explanation to substantiate such a trend. Signify stated
that research indicates that for a magnetic transformer (or magnetic
ballast) energy efficiency increases with the transformer power rate.
To align with this trend, Signify suggested DOE change its proposed EL
1 equation from -0.000008*P + 0.946 to 0.00001*P + 0.928 for the >1,000
W and <=2,000 W equipment class. (Signify, No. 13 at pp. 2-5)
NEMA also stated that based on its calculations DOE was proposing a
93 percent efficiency for ballasts operating lamps at 1,000 W and 92
percent efficiency for those operating lamps at 2,000 W and it was
unusual for efficiency requirements to decrease as wattage increases.
(NEMA, No. 12 at p. 3) NEMA also stated that the proposed levels for
the >1,000 W and <=2,000 W equipment class appear technologically
feasible. However, NEMA stated that because these products are not
currently subject to standards and thus have no certified products, it
cannot comment in detail on potential product availability. (NEMA, No.
12 at p. 3)
In developing the equation for the >1,000 W to <=2,000 W equipment
class DOE prioritized maintaining a continuous equation across product
classes. Ballasts in the >1,000 W to <=2,000 W equipment class are not
currently subject to standards and therefore are not certified in DOE's
compliance certification database. Based on the limited data available,
maintaining a continuous equation resulted in a slight negative slope
for the efficiency level equation.
Table IV.12 summarizes the efficiency requirements and associated
equations

at each EL for the representative equipment classes. See chapter 5 of
this final determination TSD for further details.

* P is defined as the rated wattage of the lamp the fixture is designed to operate.
** For this equipment class the EL 2 specified in the August 2020 NOPD was the same as EL 3. For clarity, only
an EL 2 is specified in this final determination.
5. Scaling to Other Equipment Classes
In the August 2020 NOPD, DOE did not directly analyze MHLFs with
ballasts that would be tested at an input voltage of 480 V. DOE
developed a scaling relationship to establish ELs for these equipment
classes. Ballasts capable of operating at 120 V or 277 V are
predominantly quad-voltage ballasts, therefore, DOE chose to compare
quad-voltage ballasts with 480 V ballasts to develop a scaling factor.
85 FR 47472, 47489-47490.
Based on its review of the compliance certification database, DOE
determined that the average reduction in ballast efficiency for 480 V
ballasts compared to quad ballasts is greater for ballasts designed to
operate lamps rated less than 150 W compared to ballasts designed to
operate lamps rated greater than or equal to 150 W. DOE developed two
separate scaling factors, one for the 50 W-150 W range and the second
for the 150 W-1000 W range. In the August 2020 NOPD for 480 V equipment
classes in the 50 W-150 W range, DOE found the average reduction in
ballast efficiency to be 3.0 percent, and for those in the 150 W-1000 W
range, DOE found the average reduction in ballast efficiency to be 1.0
percent. DOE applied these scaling factors to the representative
equipment class EL equations to develop corresponding EL equations for
ballasts tested at an input voltage of 480 V. Accordingly, for the non-
representative equipment classes DOE applied a multiplier of 0.97 for
equations in the 50 W-150 W range and of 0.99 for equations in the 150
W-1000 W range. 85 FR 47472, 47489-47490.
DOE received comments on the scaled ELs proposed in the August 2020
NOPD. For >=50 W and <=100 W equipment class tested at 480 V, NEMA
stated that a valid max tech proposal for magnetic ballasts is achieved
with a 2 percent reduction of EL 1. (NEMA, No. 12 at p. 2) For the >100
W and <150 W equipment class tested at 480 V, NEMA stated that based on
its review of products in DOE's compliance certification database only
EL 1 was technologically feasible. (NEMA, No. 12 at p. 2)
DOE reviewed the 3 percent scaling factor for the equipment classes
tested at 480 V in the 50 W-150 W range proposed in the August 2020
NOPD. Specifically, DOE reexamined the efficiencies of certified
products in this equipment class to ascertain the reduction in ELs for
the corresponding representative equipment class that would allow
products to meet max tech levels. Per this review, DOE is revising the
scaling factor to result in a 12 percent reduction (i.e., multiplier of
0.88) rather than a 3 percent reduction (i.e., multiplier of 0.97) to
allow certified products to meet the max tech level. DOE determined
that this adjustment results in EL 1 and EL 2 for the 480 V 50 W-150 W
equipment classes requiring a minimum efficiency less stringent than
the existing minimum standard. Hence, in this analysis, for equipment
classes in the 50 W-150 W range tested at 480 V to prevent backsliding
DOE maintained the current standard for EL 1 and EL 2 for this
analysis. For EL 3, DOE applied a 0.88 multiplier (as determined above)
to the corresponding representative equipment class EL 3 to develop a
scaled EL 3 for this analysis.
For the >250 W and <=500 W equipment class tested at 480 V, NEMA
stated that the 1 percent scaling factor still does not allow any
products in DOE's compliance certification database to meet the
proposed ELs, making them technologically infeasible. (NEMA, No. 12 at
p. 3) Signify stated that the proposed EL 1 for the >500 W and <=1,000
W equipment class tested at 480V did not seem technologically feasible.
Signify stated that such an efficiency for a magnetic ballast seemed
impractical, particularly when there has been no research or innovation
for the product. (Signify, No. 13 at pp. 6-8)
DOE identified ballasts in DOE's compliance certification database
that are in the >500 W and <=1,000 W tested at 480 V equipment class
and meet the proposed EL 1 (max tech) for this equipment class.
However, DOE did determine adjustments were needed to EL 1 (max tech)
for the >250 W and <=500 W equipment class tested at 480 V to allow for
certified products to meet it. Hence, DOE reviewed the 1 percent
scaling factor for the equipment classes tested at 480 V in the 150 W-
1,000 W range proposed in the August 2020 NOPD. 85 FR 47472, 47489-
47490. Per this review, DOE is revising the scaling factor to result in
a 4 percent reduction (i.e., multiplier of 0.96) rather than a 1
percent reduction (i.e., multiplier of 0.99) to allow certified
products to meet max tech. DOE determined that this adjustment results
in EL 1 and EL 2 for equipment classes in the 150 W-1,000 W range
requiring a minimum efficiency less stringent than the existing minimum
standard. Hence, in this analysis, for equipment classes in the 150 W-
1,000 W range tested at 480 V to prevent backsliding DOE maintained the
current standard for EL 1 and EL 2 for
[[Page 58777]]
this analysis. For EL 3, DOE applied a 0.96 multiplier (as determined
above) to the corresponding representative equipment class EL 3 to
develop the scaled EL 3 for this analysis.
Additionally, Signify stated the ELs in the August 2020 NOPD
resulted in an energy efficiency for a ballast from the >500 W and
<1,000 W equipment class tested at 480 V that is higher than ballast
efficiency of the equipment class with the same wattage range but
tested at other voltages. Signify stated that the opposite was true for
all other equipment classes. (Signify, No. 13 at p. 6) Specifically,
Signify stated that to meet the proposed EL 1 a ballast operating a
1,000 W lamp tested at 480 V would require an efficiency of 0.971 while
the same ballast tested at 277 V would require 0.936. Hence for the
>500 W and <=1,000 W equipment class for ballasts tested at 480 V,
Signify suggested DOE not adopt the proposed EL1 and instead maintain
the existing standard. (Signify, No. 13 at p. 8)
In the August 2020 NOPD DOE specified the scaled equation for EL 1
of the >500 W and <=1,000 W equipment class tested at 480 V as
0.99*(0.0001*P+0.881). 85 FR 47472, 47489-47490. The coefficient in
this equation was erroneously rounded in Table IV.13 of the August 2020
NOPD and is correctly specified in this final determination as
0.99*(0.000057*P+0.881). With this correction, ballasts in the >500 W
and <=1,000 W equipment class tested at 480 V must meet a lower minimum
efficiency than the same ballasts tested at voltages other than 480 V.
However, as noted above, to prevent backsliding DOE maintained current
standard for EL 1 of the >500 W and <=1,000 W equipment class tested at
480 V for this analysis.
In the August 2020 NOPD and in this final determination, for
ballasts greater than 1,000 W, DOE determined the need for a scaling
factor based on manufacturer catalog data. DOE determined that ballasts
greater than 1,000 W do not show a difference in efficiency between 480
V and non-480 V ballasts. DOE did not apply a scaling factor to develop
efficiency levels for 480 V ballasts in this equipment class, however,
DOE continues to consider the 480 V and non-480 V equipment classes
separately for MHLFs greater than 1,000 W for the purposes of this
analysis. 85 FR 47472, 47489-47490.
Table IV.13 summarizes the efficiency requirements at each EL for
the non-representative equipment classes. See chapter 5 of this final
determination TSD for further details.

* P is defined as the rated wattage of the lamp the fixture is designed to operate.
** For this equipment class the EL 2 specified in the August 2020 NOPD was the same as EL 3. For clarity, only
an EL 2 is specified in this final determination.
6. Manufacturer Selling Price
DOE develops manufacturer selling prices (``MSPs'') for covered
equipment and applies markups to create end-user prices to use as
inputs to the LCC analysis and NIA. The MSP of a MHLF comprises of the
MSP of the fixture components including any necessary additional
features and the MSP of the metal halide ballast contained in the
fixture. For the August 2020 NOPD, DOE conducted teardown analyses on
31 commercially available MHLFs and the ballasts included in these
fixtures. Using the information from these teardowns, DOE summed the
direct material, labor, and overhead costs used to manufacture a MHLF
or MH ballast, to calculate the manufacturing production cost
(``MPC'').\12\ DOE then determined the MSPs of fixture components and
more-efficient MH ballasts identified for each EL. 85 FR 47472, 47490-
47491.
---------------------------------------------------------------------------
\12\ When viewed from the company-wide perspective, the sum of
all material, labor, and overhead costs equals the company's sales
cost, also referred to as the cost of goods sold.
---------------------------------------------------------------------------
To determine the fixture components MSPs, DOE conducted fixture
teardowns to derive MPCs of empty fixtures (i.e., lamp enclosure and
optics). The empty fixture does not include the ballast or lamp. DOE
then added the other components required by the system (including
ballast and any cost adders associated with electronically ballasted
systems) and applied appropriate markups to obtain a final MSP for the
entire fixture. 85 FR 47472, 47490-47491.
To calculate an empty fixture price, DOE first identified the
applications commonly served by the representative wattage in each
equipment class based on DOE's compliance certification database. DOE
selected the most popular fixture types for both indoor and outdoor
applications. The representative fixture types for each equipment class
selected in the August 2020 NOPD are shown in Table IV.14. 85 FR 47472,
47490.

* Includes 150 W fixtures initially exempted by EISA 2007, which are fixtures rated only for 150 watt lamps;
rated for use in wet locations, as specified by the NFPA 70-2002, section 410.4(A); and containing a ballast
that is rated to operate at ambient air temperatures above 50 [deg]C, as specified by UL 1029-2007.
** Excludes 150 W fixtures initially exempted by EISA 2007, which are fixtures rated only for 150 watt lamps;
rated for use in wet locations, as specified by the NFPA 70-2002, section 410.4(A); and containing a ballast
that is rated to operate at ambient air temperatures above 50 [deg]C, as specified by UL 1029-2007.
DOE then used teardown information for 31 fixtures that spanned the
representative wattages and the applications identified for each
representative wattage. The MPC of the empty fixture for each
representative wattage was calculated by weighting the empty fixture
cost for each application by the popularity of each application. DOE
determined the weightings based on the number of fixtures for each
application at each representative wattage in DOE's certification
database. 85 FR 47472, 47490-47491.
The empty fixture MPCs remained the same at each magnetic
efficiency level but incremental costs were added when the fixture
contained an electronic ballast. Specifically, in the August 2020 NOPD,
DOE applied cost adders to fixtures that use electronic ballasts for
(1) transient protection, (2) thermal management, and (3) 120 V
auxiliary power functionality. These costs varied based on whether the
fixture application was indoor, indoor industrial, or outdoor. 85 FR
47472, 47491.
In the August 2020 NOPD DOE conducted market research to determine
the prices of each cost adder. DOE determined the price of voltage
transient protection to be $9.03. DOE determined that the increase in
the empty fixture cost to be 20 percent for adding thermal management
to a fixture. DOE determined the average market price of the 120 V
auxiliary tap to be $7.38. DOE added these costs to the empty fixture
MPC for outdoor and indoor industrial fixtures at ELs requiring an
electronic ballast. Because the auxiliary tap is needed in only 10
percent of the ballasts in indoor fixtures, DOE added $0.74 to the
indoor empty fixture MPC for ELs requiring an electronic ballast. 85 FR
47472, 47491.
In the August 2020 NOPD, DOE applied a fixture manufacturer markup
of 1.58 to the empty fixture MPC to determine the MSP of the fixture at
each EL. DOE maintained the manufacturer markup developed in the 2014
MHLF final rule. In that rule, DOE determined the fixture manufacturer
markup to be 1.58 based on financial information from manufacturers'
SEC 10-K reports, as well as feedback from manufacturer interviews. 85
FR 47472, 47491.
For the August 2020 NOPD, to determine the MPCs of the metal halide
ballasts identified in this analysis, DOE used data from the teardown
analysis which included cost data for magnetic ballasts at the baseline
in each equipment class. To determine the ballast MPC at the higher
efficiency levels, DOE developed a ratio between the average retail
price of ballasts at the efficiency level under consideration and
ballasts at the baseline. DOE collected retail prices from electrical
distributors (e.g., Grainger, Graybar) as well as internet retailers to
determine average retail prices for ballasts. For ELs without retail
prices available, DOE used a ratio between the same efficiency levels
in a different wattage class or interpolated based on efficiency and
ballast MPC. 85 FR 47472, 47491.
In the August 2020 NOPD, DOE applied a ballast manufacturer markup
of 1.47 to the empty fixture MPC to determine the MSP of the fixture at
each EL. DOE maintained the manufacturer markup developed in the 2014
MHLF final rule. In that rule, DOE determined the ballast manufacturer
markup to be 1.47 based on financial information from manufacturers'
SEC 10-K reports, as well as feedback from manufacturer interviews. 79
FR 7746, 7783
The CA IOUs stated that DOE used cost assumptions for lamps,
ballasts, and housing from the previous rulemaking which was conducted
six years ago and did not provide empirical data to support that the
assumptions were still valid given the evolving lighting market. (CA
IOUs, No. 14, p. 2)
As noted, DOE developed fixture and ballast prices based on
teardowns and retail price collections conducted for this analysis.
Additionally, DOE conducted market research for this rulemaking to
confirm the cost adder estimates used in the 2014 MHLF final rule. DOE
determined that there are likely minimal changes to the financial
structure of fixture or ballast manufacturers and therefore, the
respective markups from the 2014 MHLF final rule remain valid.
DOE is maintaining the results of MSPs determined in the August
2020 NOPD for this final determination. The total empty fixture MSPs,
replacement ballast MSPs, and fixture with ballast MSPs are detailed in
chapter 5 of the final determination TSD.
D. Markups Analysis
The markups analysis develops appropriate markups (e.g.,
manufacturer markups, retailer markups, distributor markups, contractor
markups) in the distribution chain and sales taxes to convert the MSP
estimates derived in the engineering analysis to consumer prices, which
are then used in the LCC and PBP analysis and in the MIA. At each step
in the distribution channel, companies mark up the price of the product
to cover business costs and profit margin. DOE used the same
distribution channels and wholesaler and contractor markups as in the
August 2020 NOPD, following the 2014 MHLF final rule, for this final
determination.
1. Distribution Channels
Before it could develop markups, DOE needed to identify
distribution channels (i.e., how the equipment is distributed from the
manufacturer to the end-user) for the MHLF designs addressed in this
rulemaking. In an electrical wholesaler distribution channel, DOE
assumed the fixture manufacturer sells the fixture to an electrical
wholesaler (i.e., distributor), who in turn sells it to a
[[Page 58779]]
contractor, who sells it to the end-user. In a contractor distribution
channel, DOE assumed the fixture manufacturer sells the fixture
directly to a contractor, who sells it to the end-user. In a utility
distribution channel, DOE assumed the fixture manufacturer sells the
fixture directly to the end-user (i.e., electrical utility). Indoor
fixtures are all assumed to go through the electrical wholesaler
distribution channel. Outdoor fixtures are assumed to go through all
three distribution channels as follows: 60 percent electrical
wholesaler, 20 percent contractor, and 20 percent utility.
2. Estimation of Markups
To estimate wholesaler and utility markups, DOE used financial data
from 10-K reports of publicly owned electrical wholesalers and
utilities. DOE's markup analysis developed both baseline and
incremental markups to transform the fixture MSP into an end-user
equipment price. DOE used the baseline markups to determine the price
of baseline designs. Incremental markups are coefficients that relate
the change in the MSP of higher-efficiency designs to the change in the
wholesaler and utility sales prices, excluding sales tax. These markups
refer to higher-efficiency designs sold under market conditions with
new and amended energy conservation standards.
In the August 2020 NOPD, DOE used the same wholesaler and
contractor markups as the 2014 MHLF final rule and assumed a wholesaler
baseline markup of 1.23 and a contractor markup of 1.13, yielding a
total wholesaler distribution channel baseline markup of 1.49. The
lower wholesaler incremental markup of 1.05 yields a lower total
incremental markup through this distribution channel of 1.27. DOE also
assumed a utility markup of 1.00 for the utility distribution channel
in which the manufacturer sells a fixture directly to the end-user. DOE
again assumed a contractor markup of 1.13 for the utility distribution
channel in which a manufacturer sells a fixture to a contractor who in
turn sells it to the end-user yielding an overall markup of 1.21 for
this channel. 85 FR 47472, 47492. DOE used these same markups for this
final determination analysis.
The sales tax represents state and local sales taxes applied to the
end-user equipment price. DOE obtained state and local tax data from
the Sales Tax Clearinghouse.\13\ These data represent weighted averages
that include state, county, and city rates. DOE then calculated
population-weighted average tax values for each census division and
large state, and then derived U.S. average tax values using a
population-weighted average of the census division and large state
values. For this final determination, this approach provided a national
average tax rate of 7.3 percent.

distribution channels and the overall baseline and incremental markups,

Using these markups, DOE generated fixture end-user prices for each
EL it considered, assuming that each level represents a new minimum
efficiency standard.
Chapter 6 of the final determination TSD provides details on DOE's
development of markups for MHLFs.
E. Energy Use Analysis
The purpose of the energy use analysis is to determine the annual
energy consumption of MHLFs at different efficiencies in the
commercial, industrial, and outdoor stationary sectors, and to assess
the energy savings potential of increased MHLF efficiency. The energy
use analysis estimates the range of energy use of MHLFs in the field
(i.e., as they are actually used by customers). The energy use analysis
provides the basis for other analyses DOE performed, particularly
assessments of the energy savings and the savings in operating costs
that could result from adoption of amended or new standards.
To develop annual energy use estimates, DOE multiplied the lamp-
and-ballast system input power (in watts) by annual usage (in hours per
year). DOE characterized representative lamp-and-ballast systems in the
engineering analysis, which provided measured input power ratings. To
characterize the country's average usage of fixtures for a typical
year, DOE developed annual operating hour distributions by sector,
using data published in the 2015 U.S. Lighting Market Characterization
(``LMC'').\14\ For the >=50 W and <=100 W to >500 W and <=1,000 W
equipment classes, DOE obtained weighted-average annual operating hours
for the commercial, industrial, and outdoor stationary sectors of
approximately 2,300 hours, 5,100 hours, and 5,000 hours, respectively.
For the 1,500 W equipment class, DOE assigned annual operating hours of
approximately 770 hours for all lamps according to the 2015 LMC
estimate of 2.1 hours per day for sports field lighting, consistent
with the methodology from the August 2020 NOPD analysis. 85 FR 47472,
47492.

Chapter 7 of the final determination TSD provides details on DOE's
energy use analysis for MHLFs.
F. Life-Cycle Cost and Payback Period Analysis
DOE conducted LCC and PBP analyses to evaluate the economic impacts
on individual customers of
[[Page 58780]]
potential energy conservation standards for MHLFs. The effect of new or
amended energy conservation standards on individual customers usually
involves a reduction in operating cost and an increase in purchase
cost. DOE used the following two metrics to measure customer impacts:
[squ] The LCC is the total customer expense of equipment over the
life of that equipment, consisting of total installed cost
(manufacturer selling price, distribution chain markups, sales tax, and
installation costs) plus operating costs (expenses for energy use,
maintenance, and repair). To compute the operating costs, DOE discounts
future operating costs to the time of purchase and sums them over the
lifetime of the equipment.
[squ] The PBP is the estimated amount of time (in years) it takes
customers to recover the increased purchase cost (including
installation) of a more-efficient equipment through lower operating
costs. DOE calculates the PBP by dividing the change in purchase cost
at higher efficiency levels by the change in annual operating cost for
the year that amended or new standards are assumed to take effect.
For any given efficiency level, DOE measured the change in LCC
relative to the LCC in the no-new-standards case, which reflects the
estimated efficiency distribution of MHLFs in the absence of new or
amended energy conservation standards. In contrast, the PBP for a given
efficiency level is measured relative to the baseline equipment.
For each considered efficiency level in each equipment class, DOE
calculated the LCC and PBP for a nationally representative set of
building types. As stated previously, DOE developed customer samples
from the 2015 LMC. For each sample customer, DOE determined the energy
consumption for the MHLF and the appropriate electricity price. By
developing a representative sample of building types, the analysis
captured the variability in energy consumption and energy prices
associated with the use of MHLFs.
Inputs to the calculation of total installed cost include the cost
of the equipment--which includes MPCs, manufacturer markups, retailer
and distributor markups, and sales taxes--and installation costs.
Inputs to the calculation of operating expenses include annual energy
consumption, energy prices and price projections, repair and
maintenance costs, equipment lifetimes, and discount rates. DOE created
distributions of values for operating hours, equipment lifetime,
discount rates, electricity prices, and sales taxes, with probabilities
attached to each value, to account for their uncertainty and
variability. For example, DOE created a probability distribution of
annual energy consumption in its energy use analysis, based in part on
a range of annual operating hours. The operating hour distributions
capture variations across building types, lighting applications, and
metal halide systems for three sectors (commercial, industrial, and
outdoor stationary). In contrast, fixture MSPs were specific to the
representative designs evaluated in DOE's engineering analysis, and
price markups were based on limited, publicly available financial data.
Consequently, DOE used discrete values instead of distributions for
these inputs.
The computer model DOE uses to calculate the LCC and PBP, which
incorporates Crystal Ball\TM\ (a commercially available software
program), relies on a Monte Carlo simulation to incorporate uncertainty
and variability into the analysis. The Monte Carlo simulations randomly
sample input values from the probability distributions and MHLF user
samples. The model calculated the LCC and PBP for equipment at each
efficiency level for 10,000 customers per simulation run. The
analytical results include a distribution of 10,000 data points showing
the range of LCC savings for a given efficiency level relative to the
no-new-standards case efficiency distribution. In performing an
iteration of the Monte Carlo simulation for a given consumer, product
efficiency is chosen based on its probability. If the chosen product
efficiency is greater than or equal to the efficiency of the standard
level under consideration, the LCC and PBP calculation reveals that a
consumer is not impacted by the standard level. By accounting for
consumers who already purchase more-efficient products, DOE avoids
overstating the potential benefits from increasing product efficiency.
DOE calculated the LCC and PBP for all customers of MHLFs as if
each were to purchase new equipment in the expected year of required
compliance with new or amended standards. Any amended standards would
apply to MHLFs manufactured three years after the date on which any new
or amended standard is published. (42 U.S.C. 6295(hh)(3)(B)) At this
time, DOE estimates publication of a final determination in the latter
half of 2021. Therefore, for purposes of its analysis, DOE used 2025 as
the first year of compliance with any amended standards for MHLFs.
Table IV.16 summarizes the approach and data DOE used to derive
inputs to the LCC and PBP calculations. The subsections that follow
provide further discussion. Details of the spreadsheet model, and of
all the inputs to the LCC and PBP analyses, are contained in chapter 8
of the final determination TSD and its appendices.

* References for the data sources mentioned in this table are provided
in the sections following the table or in chapter 8 of the final
determination TSD.
1. Equipment Cost
To calculate customer equipment costs, DOE multiplied the MSPs
developed in the engineering analysis by the markups described
previously (along with sales taxes). DOE used different markups for
baseline equipment and higher-efficiency equipment, because DOE applies
an incremental markup to the increase in MSP associated with higher-
efficiency equipment. See section IV.D for further details.
2. Installation Cost
Installation cost is the cost to install the fixture such as the
labor, overhead, and any miscellaneous materials and parts needed. DOE
used the installation costs from the 2014 MHLF final rule, but inflated
to 2020$ using the GDP price deflator.\15\

---------------------------------------------------------------------------
3. Annual Energy Consumption
For each sampled customer, DOE determined the energy consumption
for an MHLF at different efficiency levels using the approach described
previously in section IV.E of this document. For this final
determination, DOE based the annual energy use inputs on sectoral
operating hour distributions (commercial, industrial, and outdoor
stationary sectors), with the exception of a discrete value
(approximately 770 hours per year) for the 1,500 W equipment class that
is primarily limited to sports lighting. DOE used operating hour (and,
by extension, energy use) distributions to better characterize the
potential range of operating conditions faced by MHLF customers.
4. Energy Prices
Because marginal electricity price more accurately captures the
incremental savings associated with a change in energy use from higher
efficiency, it provides a better representation of incremental change
in consumer costs than average electricity prices. Therefore, DOE
applied average electricity prices for the energy use of the product
purchased in the no-new-standards case, and marginal electricity prices
for the incremental change in energy use associated with the other
efficiency levels considered in this final determination.
DOE derived annual electricity prices in 2019 for each census
division using data from the Edison Electric Institute (EEI) Typical
Bills and Average Rates reports.\16\ Marginal prices depend on both the
change in electricity consumption and the change in monthly peak-
coincident demand. DOE used the EEI data to estimate both marginal
energy charges and marginal demand charges.

5. Replacement Costs
Replacement costs include the labor and materials costs associated
with replacing a ballast or lamp at the end of their lifetimes and are
annualized across the years preceding and including the actual year in
which equipment is replaced. The costs are taken from the 2014 MHLF
final rule but inflated to 2020$ using the GDP price deflator. For the
LCC and PBP analysis, the analysis period corresponds with the fixture
lifetime that is assumed to be longer than that of either the lamp or
the ballast. For this reason, ballast and lamp prices and labor costs
associated with lamp or ballast replacements are included in the
calculation of operating costs.
The CA IOUs suggested that DOE update the MHLF cost data for lamps,
ballasts, and housings, rather than using the costs from the 2014 MHLF
final rule. (CA IOUs, No. 14 at p. 2) DOE notes that replacement costs
for ballasts come directly from this final determination engineering
analysis (see section IV.C). However, DOE has continued to use the
replacement lamp costs from the 2014 MHLF final rule (but inflated to
2020$). The CA IOUs acknowledged that MHLFs are a legacy lighting
technology, and NEMA stated that there has been an 80 percent decline
in the MHLFs market from 2008-2018. (CA IOUs, No. 14 at pp. 1-2; NEMA,
No. 12 at p. 2) Given this recent substantial decline in the MHLFs
market, it is unlikely that prices would have changed appreciably due
to price learning since the 2014 MHLF final rule analysis was
conducted. Therefore, DOE has only applied inflation to the MHLF
replacement lamp prices since the 2014 MHLF final rule analysis.
6. Equipment Lifetime
DOE defined equipment lifetime as the age when a fixture, ballast,
or lamp is retired from service. For fixtures in all equipment classes,
DOE assumed average lifetimes for indoor and outdoor fixtures of 20 and
25 years, respectively. DOE also assumed that magnetic ballasts had a
rated lifetime of 50,000 hours and electronic ballasts had a rated
lifetime of 40,000 hours. DOE used manufacturer catalog data to obtain
rated lifetime estimates (in hours) for lamps in each equipment class.
DOE accounted for uncertainty in the fixture, ballast, and lamp
lifetimes by applying Weibull survival distributions to the components'
rated lifetimes. Furthermore, DOE included a residual value calculation
for lamps and ballasts to account for the residual monetary value
associated with the remaining life in the lamp and ballast at the end
of the fixture lifetime. As stated in the 2020 NOPD, DOE based all
assumptions for estimating equipment lifetime from the 2014 MHLF final
rule. 85 FR 47472, 47494.
7. Discount Rates
The discount rate is the rate at which future expenditures are
discounted to
[[Page 58782]]
estimate their present value. In this final determination, DOE
estimated separate discount rates for commercial, industrial, and
outdoor stationary applications. DOE used discount rate data from a
2019 Lawrence Berkeley National Laboratory report.\18\ The average
discount rates, weighted by the shares of each rate value in the
sectoral distributions, are 8.3 percent for commercial end-users, 8.8
percent for industrial end-users, and 3.2 percent for outdoor
stationary end-users. For more information regarding discount rates,
see chapter 8 of the final determination TSD.

8. Energy Efficiency Distribution in the No-New-Standards Case
DOE developed a no-new-standards case efficiency distribution using
model count data from the compliance certification database collected
on May 5, 2021. The compliance certification database does not contain
models in the >1,000 W and <=2,000 W equipment class; therefore, DOE
assumed 56 percent of the market is at the baseline and 44 percent of
the market is at EL 1, based on MHLF catalog data. The complete
efficiency distribution for 2025 is shown in Table IV.17.
Table IV.17--MHLF Efficiency Distribution by Equipment Class for 2025
--------------------------------------------------------------------------------------------------------------------------------------------------------

* Columns may not sum to 100% due to rounding.
See chapter 8 of the final determination TSD for further
information on the derivation of the efficiency distributions.
9. Payback Period Analysis
The payback period is the amount of time it takes the consumer to
recover the additional installed cost of more-efficient products,
compared to baseline products, through energy cost savings. Payback
periods are expressed in years. Payback periods that exceed the life of
the product mean that the increased total installed cost is not
recovered in reduced operating expenses.
The inputs to the PBP calculation for each efficiency level are the
change in total installed cost of the product and the change in the
first-year annual operating expenditures relative to the baseline. The
PBP calculation uses the same inputs as the LCC analysis, except that
discount rates are not needed.
As noted previously, EPCA establishes a rebuttable presumption that
a standard is economically justified if the Secretary finds that the
additional cost to the consumer of purchasing a product complying with
an energy conservation standard level will be less than three times the
value of the first year's energy savings resulting from the standard,
as calculated under the applicable test procedure. (42 U.S.C.
6295(o)(2)(B)(iii)) For each considered efficiency level, DOE
determined the value of the first year's energy savings by calculating
the energy savings in accordance with the applicable DOE test
procedure, and multiplying those savings by the average energy price
projection for the year in which compliance with the amended standards
would be required.
G. Shipments Analysis
DOE uses projections of annual equipment shipments to calculate the
national impacts of potential amended or new energy conservation
standards on energy use and NPV.\19\ The shipments model takes an
accounting approach, tracking market shares of each equipment class and
the vintage of units in the stock. Stock accounting uses equipment
shipments as inputs to estimate the age distribution of in-service
equipment stocks for all years. The age distribution of in-service
equipment stocks is a key input to calculations of both the NES and
NPV, because operating costs for any year depend on the age
distribution of the stock.
---------------------------------------------------------------------------
\19\ DOE uses data on manufacturer shipments as a proxy for
national sales, as aggregate data on sales are lacking. In general,
one would expect a close correspondence between shipments and sales.
---------------------------------------------------------------------------
The stock turnover model calculates demand for new MHLFs based on
the expected demand for replacement MHLFs and the decrease in MHLF
demand due to the adoption of out-of-scope LED alternatives. The model
is initialized using a time series of historical shipments data
compiled from the 2014 MHLF final rule and data from NEMA. The
historical shipments for 2008 from the 2014 MHLF final rule were
projected to 2018 using NEMA sales indices from 2008 to 2018. 79 FR
7746, 7788-89. DOE used NEMA provided sales indices for the second
quarter of 2020 for metal halide lamps to project the historical
shipments forward to 2020.\20\ The updated projection from the NEMA
data gives a faster decline of historical shipments compared to the
projection used in the MHLF NOPD. 85 FR 47472, 47495.

---------------------------------------------------------------------------
NEMA commented in their response to the MHLF NOPD that the market
for MHLFs has continued to show a steady decline since the July 2019
RFI in favor of LED Technology. (NEMA, No. 12 at p. 2) With the
diminishing shipments there is no reasonable possibility of industry
recovering investments in new conservation standards of MHLFs. As in
the previous rulemaking, DOE continued to assume that an increasing
fraction of the MHLF market will move to out-of-scope LED alternatives
over the course of the shipments analysis period. 85 FR 47472, 47495.
DOE modelled the incursion of LED equipment in the form of a Bass
diffusion curve.\21\ The parameters for the Bass diffusion curve are
based on fitting a Bass diffusion curve to market share data for
general service LED lamps based on data
[[Page 58783]]
published by NEMA. This same approach was used in the final
determination for general service incandescent lamps (GSILs); see
chapter 9 of that final determination TSD.\22\ 84 FR 71626 (December
27, 2019).

at www.regulations.gov/document?D=EERE-2019-BT-STD-0022-0116.
---------------------------------------------------------------------------
The CA IOUs commented on the MHLF NOPD that DOE's current A-Line
based shipment curves approach to modelling shipments for MHLF products
should be replaced by a diffusion curve based on linear fluorescent
shipments. (CA IOUs, No. 14 at p. 2) However, DOE found that a Bass
diffusion curve based on market share data for general service LED
lamps provided a better fit to the historic MHLF shipments data from
NEMA than a Bass diffusion curve based on linear fluorescent shipments,
and NEMA expressed support for the shipment declines projected in the
NOPD. (NEMA, No. 12 at p. 2) Additionally, the lighting power allowance
from the 2019 update to ASHRAE 90.1, noted during the MHLF NOPD public
meeting, suggests a rapid transition to LED technology. (EEI, Public
Meeting Transcript, No. 11 at p. 47) As a result, DOE continued to base
the Bass diffusion model on market share data for general service LED
lamps for this final determination.
Another key input to the national impacts analysis is the
distribution of MHLF shipments by EL in the no-new standards case and
the standards cases. DOE apportioned the total shipments of MHLFs to
each EL in the no-new-standards case using data downloaded from the
compliance certification database \23\ and data provided by NEMA in
comments to the July 2019 RFI. (NEMA, No. 3 at pp. 11-14). Equipment
listed in the CCMS database were categorized by equipment class,
efficiency level, and ballast type. The counts for each category were
scaled based on ballast type by the NEMA market shares for magnetic and
electronic ballasts reported in 2018.
---------------------------------------------------------------------------
\23\ See www.regulations.doe.gov/certification-data/products.html (Last accessed on May 5, 2021).
---------------------------------------------------------------------------
For the standards cases, DOE used a ``roll-up'' approach to
estimate market share for each EL for the year that standards are
assumed to become effective (2025). For each standards case, the market
shares of ELs in the no-new-standards case that do not meet the
standard under consideration ``roll up'' to meet the new standard
level, and the market share of equipment above the standard remains
unchanged.
For both the no-new-standards and standards cases, DOE assumed no
efficiency trend over the analysis period. For a given case, market
shares were held fixed to their 2025 distribution.
DOE typically includes the impact of price learning in its
analysis. In a standard price learning model,\24\ the price of a given
technology is related to its cumulative production, as represented by
total cumulative shipments. DOE assumed MHLFs have reached a stable
price point due to the high volume of total cumulative shipments and
would not undergo price learning in this final determination analysis.

H. National Impact Analysis
The NIA assesses the NES and the NPV from a national perspective of
total customer costs and savings that would be expected to result from
new or amended standards at specific efficiency levels.\25\ DOE
calculates the NES and NPV for the potential standard levels considered
based on projections of annual equipment shipments, along with the
annual energy consumption and total installed cost data from the energy
use and LCC analyses. For the present analysis, DOE projected the
energy savings, operating cost savings, equipment costs, and NPV of
customer benefits over the lifetime of MHLFs sold from 2025 through
2054.
---------------------------------------------------------------------------
\25\ The NIA accounts for impacts in the 50 states and U.S.
territories.
---------------------------------------------------------------------------
DOE evaluates the impacts of new or amended standards by comparing
a case without such standards with standards-case projections. The no-
new-standards case characterizes energy use and customer costs for each
equipment class in the absence of new or amended energy conservation
standards. DOE compares the no-new-standards case with projections
characterizing the market for each equipment class if DOE adopted new
or amended standards at specific energy efficiency levels (i.e., the
TSLs or standards cases) for that class. For the standards cases, DOE
considers how a given standard would likely affect the market shares of
equipment with efficiencies greater than the standard.
DOE uses a spreadsheet model to calculate the energy savings and
the national customer costs and savings from each TSL. Interested
parties can review DOE's analyses by changing various input quantities
within the spreadsheet. The NIA spreadsheet model uses typical values
(as opposed to probability distributions) as inputs.
Table IV.18 summarizes the inputs and methods DOE used for the NIA
analysis for this final determination. Discussion of these inputs and
methods follows the table. See chapter 10 of the final determination
TSD for further details.

1. National Energy Savings
The national energy savings analysis involves a comparison of
national energy consumption of the considered equipment between each
potential TSL and the case with no new or amended energy conservation
standards. DOE calculated the national energy consumption by
multiplying the number of units (stock) of each equipment type (by
vintage or age) by the unit energy consumption (also by vintage). DOE
calculated annual NES based on the difference in national energy
consumption for the no-new standards case and for each higher
efficiency standard case. DOE estimated energy consumption and savings
based on site energy and converted the electricity consumption and
savings to primary energy (i.e., the energy consumed by power plants to
generate site electricity) using annual conversion factors derived from
AEO 2021. Cumulative energy savings are the sum of the NES for each
year over the timeframe of the analysis.
DOE generally accounts for the direct rebound effect in its NES
analyses. Direct rebound reflects the idea that as appliances become
more efficient, customers use more of their service because their
operating cost is reduced. In the case of lighting, the rebound effect
could be manifested in increased hours of use or in increased lighting
density (lumens per square foot). In response to the July 2019 RFI,
NEMA commented that a rebound rate of 0 is appropriate. (NEMA, No. 3 at
p. 9) DOE assumed no rebound effect for MHLFs in this final
determination.
In 2011, in response to the recommendations of a committee on
``Point-of-Use and Full-Fuel-Cycle Measurement Approaches to Energy
Efficiency Standards'' appointed by the National Academy of Sciences,
DOE announced its intention to use FFC measures of energy use and
greenhouse gas and other emissions to the extent that emissions
analyses are conducted. 76 FR 51281 (Aug. 18, 2011). After evaluating
the approaches discussed in the August 18, 2011 notice, DOE published a
statement of amended policy in which DOE explained its determination
that Energy Information Administration's (EIA's) National Energy
Modeling System (``NEMS'') is the most appropriate tool for its FFC
analysis and its intention to use NEMS for that purpose. 77 FR 49701
(Aug. 17, 2012). NEMS is a public domain, multi-sector, partial
equilibrium model of the U.S. energy sector \26\ that EIA uses to
prepare its Annual Energy Outlook. The FFC factors incorporate losses
in production and delivery in the case of natural gas (including
fugitive emissions) and additional energy used to produce and deliver
the various fuels used by power plants. The approach used for deriving
FFC measures of energy use and emissions is described in appendix 10B
of the final determination TSD.

Modeling System: An Overview 2009, DOE/EIA-0581(2009), October 2009.

---------------------------------------------------------------------------
2. Net Present Value Analysis
The inputs for determining the NPV of the total costs and benefits
experienced by customers are (1) total annual installed cost, (2) total
annual operating costs (energy costs and repair and maintenance costs),
and (3) a discount factor to calculate the present value of costs and
savings. DOE calculates net savings each year as the difference between
the no-new-standards case and each standards case in terms of total
savings in operating costs versus total increases in installed costs.
DOE calculates operating cost savings over the lifetime of equipment
shipped during the analysis period.
Energy cost savings, which are part of operating cost savings, are
calculated using the estimated energy savings in each year and the
projected price of the appropriate form of energy. To estimate energy
prices in future years, DOE multiplied the average national marginal
electricity prices by the forecast of annual national-average
commercial or industrial electricity price changes in the Reference
case from AEO 2021, which has an end year of 2050. To estimate price
trends after 2050, DOE used the average annual rate of change in prices
from 2041 to 2050.
DOE includes the cost of replacing failed lamps and ballasts over
the course of the lifetime of the fixture. DOE assumed that lamps and
ballasts were replaced at their rated lifetime. When replacing a
ballast, DOE assumed the lamp was also replaced at the same time,
independent of the timing of the previous lamp replacement. For more
details see chapter 10 of the final determination TSD.
DOE also estimates the residual monetary value remaining in the
lamp and ballast at the end of the fixture lifetime and applies it as a
credit to operating costs (i.e., the residual value is deducted from
operating costs). See chapter 10 of the final determination TSD for
more details on DOE's calculation of the residual value.
In calculating the NPV, DOE multiplies the net savings in future
years by a discount factor to determine their present value. For this
final determination, DOE estimated the NPV of customer benefits using
both a 3-percent and a 7-percent real discount rate. DOE uses these
discount rates in accordance with guidance provided by the Office of
Management and Budget (``OMB'') to Federal agencies on the development
of regulatory analysis.\27\ The discount rates for the determination of
NPV are in contrast to the discount rates used in the LCC analysis,
which are designed to reflect a customer's perspective. The 7-percent
real value is an estimate of the average before-tax rate of return to
private capital in the U.S. economy. The 3-percent real value
represents the ``social rate of time preference,'' which is the rate at
which society discounts future consumption flows to their present
value.

V. Analytical Results and Conclusions
The following section addresses the results from DOE's analyses
with respect to the considered energy conservation standards for MHLFs.
It addresses the TSLs examined by DOE and the projected impacts of each
of these levels. Additional details regarding DOE's analyses are
contained in the final determination TSD supporting this document.
A. Trial Standard Levels
DOE analyzed the benefits and burdens of three TSLs for MHLFs. TSL
1 is composed of EL 1 for all equipment classes. TSL 2 is composed of
the efficiency levels corresponding to the least efficient electronic
ballast level for each equipment class, if any efficiency levels
corresponding to an electronic ballast exist. TSL 3 is composed of the
max-tech level for each equipment class. Table V.1 presents the TSLs
and the corresponding efficiency levels that DOE has identified for
potential amended energy conservation standards for MHLFs.

--------------------------------------------------------------------------------------------------------------------------------------------------------
B. Economic Justification and Energy Savings
1. Economic Impacts on Individual Customers
DOE analyzed the economic impacts on MHLF customers by looking at
the effects that potential amended standards at each TSL would have on
the LCC and PBP. These analyses are discussed in the following
sections.
a. Life-Cycle Cost and Payback Period
In general, higher-efficiency products affect consumers in two
ways: (1) Purchase price increases and (2) annual operating costs
decrease.\28\ Inputs used for calculating the LCC and PBP include total
installed costs (i.e., product price plus installation costs), and
operating costs (i.e., annual energy use, energy prices, energy price
trends, and replacement costs). The LCC calculation also uses product
lifetime and a discount rate. Chapter 8 of the final determination TSD
provides detailed information on the LCC and PBP analyses.
---------------------------------------------------------------------------
\28\ While it is generally true that higher-efficiency equipment
has lower operating costs, MHLF operating costs in this analysis
also incorporate the costs of lamp and ballast replacements. Due to
these replacement costs, higher operating costs can be experienced
at efficiency levels above the baseline.
---------------------------------------------------------------------------
Table V.2 through Table V.13 show the LCC and PBP results for the
ELs and TSLs considered for each equipment class, with indoor and
outdoor installations aggregated together using equipment shipments in
the analysis period start year (2025). The results provided here will
differ from the LCC and PBP results from the NOPD due to updated data
used for this final determination. Results for each equipment class are
shown in two tables. In the first table, the simple payback is measured
relative to the baseline product. For ELs having a higher first year's
operating cost than that of the baseline, the payback period is
``Never,'' because the additional installed cost relative to the
baseline is not recouped. In the second table, impacts are measured
relative to the efficiency distribution in the no-new-standards case in
the compliance year (see section IV.F.8 of this document). Because some
customers purchase products with higher efficiency in the no-new-
standards case, the average savings are less than the difference
between the average LCC of the baseline product and the average LCC at
each TSL. The savings refer only to customers who are affected by a
standard at a given TSL. Those who already purchase equipment with
efficiency at or above a given TSL are not affected. Customers for whom
the LCC increases at a given TSL experience a net cost.

b. Rebuttable Presumption Payback
As discussed in section IV.F.9, EPCA establishes a rebuttable
presumption that an energy conservation standard is economically
justified if the increased purchase cost for a product that meets the
standard is less than three times the value of the first-year energy
savings resulting from the standard. In calculating a rebuttable
presumption payback period for each of the considered ELs, DOE used
discrete values, and, as required by EPCA, based the energy use
calculation on the DOE test procedures for MHLFs. In contrast, the PBPs
presented in section V.B.1.a were calculated using distributions that
reflect the range of energy use in the field.
Table V.14 presents the rebuttable-presumption payback periods for
the considered ELs for MHLFs. While DOE examined the rebuttable-
presumption criterion, it considered whether the standard levels
considered for this rule are economically justified through a more
detailed analysis of the economic impacts of those levels, pursuant to
42 U.S.C. 6295(o)(2)(B)(i), that considers the full range of impacts to
the consumer, manufacturer, Nation, and environment. The results of
that analysis serve as the basis for DOE to definitively evaluate the
economic justification for a potential standard level, thereby
supporting or rebutting the results of any preliminary determination of
economic justification.

Table V.14 reports very large rebuttable-presumption payback
periods for some equipment class-efficiency level combinations. These
payback periods are the result of very small operating cost savings
under the rebuttable-presumption criterion compared to the increased
installed cost of moving from EL 0 to the EL under consideration.
2. National Impact Analysis
This section presents DOE's estimates of the national energy
savings and the NPV of consumer benefits that would result from each of
the TSLs considered as potential amended standards.
a. Significance of Energy Savings
To estimate the energy savings attributable to potential amended
standards for MHLFs DOE compared their energy consumption under the no-
new-standards case to their anticipated energy consumption under each
TSL. The savings are measured over the entire lifetime of products
purchased in the 30-year period that begins in the first full year of
anticipated compliance with amended standards 2025-2054. Table V.15
presents DOE's projections of the national energy savings for each TSL
considered for MHLFs. The savings were calculated using the approach
described in section IV.H.1 of this document.

OMB Circular A-4 \29\ requires agencies to present analytical
results, including separate schedules of the monetized benefits and
costs that show the type and timing of benefits and costs. Circular A-4
also directs agencies to consider the variability of key elements
underlying the estimates of benefits and costs. For this rulemaking,
DOE undertook a sensitivity analysis using 9 years, rather than 30
years, of product shipments. The choice of a 9-year period is a proxy
for the timeline in EPCA for the review of certain energy conservation
standards and potential revision of and compliance with such revised
standards.\30\ The review timeframe established in EPCA is generally
not synchronized with the product lifetime, product manufacturing
cycles, or other factors specific to MHLFs. Thus, such results are
presented for informational purposes only and are not indicative of any
change in DOE's analytical methodology. The NES sensitivity analysis
results based on a 9-year analytical period are presented in Table
V.16. The impacts are counted over the lifetime of MHLFs purchased in
2025-2033.

\30\ Section 325(m) of EPCA requires DOE to review its standards
at least once every 6 years, and requires, for certain products, a
3-year period after any new standard is promulgated before
compliance is required, except that in no case may any new standards
be required within 6 years of the compliance date of the previous
standards. While adding a 6-year review to the 3-year compliance
period adds up to 9 years, DOE notes that it may undertake reviews
at any time within the 6 year period and that the 3-year compliance
date may yield to the 6-year backstop. A 9-year analysis period may
not be appropriate given the variability that occurs in the timing
of standards reviews and the fact that for some products, the
compliance period is 5 years rather than 3 years.

The previous results reflect the use of a default trend to estimate
the change in price for MHLFs over the analysis period (see section
IV.H.2 of this document). DOE also conducted a sensitivity analysis
that considered one scenario with a lower rate of price decline than
the reference case and one scenario with a higher rate of price decline
than the reference case. The results of these alternative cases are
presented in appendix 10C of the final determination TSD. In the high-
price-decline case, the NPV of consumer benefits is higher than in the
default case. In the low-price-decline case, the NPV of consumer
benefits is lower than in the default case.
C. Final Determination
For this final determination, DOE analyzed whether amended
standards for MHLFs would be technologically feasible and cost
effective. (42 U.S.C. 6295(m)(1)(A) and 42 U.S.C. 6295(n)(2)) EPCA
mandates that DOE consider whether amended energy conservation
standards for MHLFs would be technologically feasible. (42 U.S.C.
6316(a); 42 U.S.C. 6295(m)(1)(A) and 42 U.S.C. 6295(n)(2)(B)) DOE has
determined that there are technology options that would improve the
efficiency of MHLFs. These technology options are being used in
commercially available MHLFs and therefore are technologically
feasible. (See section IV.B for further information.) Hence, DOE has
determined that amended energy conservation standards for MHLFs are
technologically feasible.
EPCA requires DOE to consider whether energy conservation standards
for MHLFs would be cost effective through an evaluation of the savings
in operating costs throughout the estimated average life of the covered
product/equipment compared to any increase in the price of, or in the
initial charges for, or maintenance expenses of, the covered products/
equipment which are/is likely to result from the imposition of an
amended standard. (42 U.S.C. 6316(a); 42 U.S.C. 6295(m)(1)(A), 42
U.S.C. 6295(n)(2)(C), and 42 U.S.C. 6295(o)(2)(B)(i)(II)) As presented
in the prior section, the average customer purchasing a representative
MHLF would experience an increase in LCC at each evaluated standards
case as compared to the no-new-standards case. The simple PBP for the
average MHLF customer at most ELs is projected to be generally longer
than the mean lifetime of the equipment, which further indicates that
the increase in installed cost for more efficient MHLFs is not recouped
by their associated operating cost savings. The NPV benefits at these
TSLs are also negative for all equipment classes at 3-percent and 7-
percent discount rates. Based on the previous considerations, DOE has
determined that more stringent amended energy conservation standards
for MHLFs cannot satisfy the relevant statutory requirements because
such standards would not be cost effective as required under EPCA. (See
42 U.S.C. 6295(n)(2); 42 U.S.C. 6295(o)(2)(B)(II); 42 U.S.C. 6316(a))
Having determined that amended energy conservation standards for
MHLFs would not be cost-effective, DOE did not further evaluate the
significance of the amount of energy conservation under the considered
amended standards because it has determined that the potential
standards would not be cost-effective (and by extension, would not be
economically justified) as required under EPCA. (42 U.S.C. 6316(a); 42
U.S.C. 6295(m)(1)(A); 42 U.S.C. 6295(n)(2); 42 U.S.C. 6295(o)(2)(B)).
VI. Procedural Issues and Regulatory Review
A. Review Under Executive Orders 12866
This final determination has been determined to be not significant
for purposes of Executive Order (``E.O.'') 12866, ``Regulatory Planning
and Review,'' 58 FR 51735 (Oct. 4, 1993). As a result, OMB did not
review this final determination.
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
[[Page 58792]]
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 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. DOE has concluded that amended energy conservation
standards for metal halide lamp fixtures would not be cost effective
(and by extension not economically justified). Because DOE is not
amending the current energy conservation standards for MHLFs, DOE
certifies that this final determination will not have a significant
economic impact on a substantial number of small entities. Accordingly,
DOE has not prepared an FRFA for this final determination. DOE will
transmit this certification and supporting statement of factual basis
to the Chief Counsel for Advocacy of the Small Business Administration
for review under 5 U.S.C. 605(b).
C. Review Under the Paperwork Reduction Act
Manufacturers of covered products must certify to DOE that their
products comply with any applicable energy conservation standards. To
certify compliance, manufacturers must first obtain test data for their
products according to the DOE test procedures, including any amendments
adopted for those test procedures. DOE has established regulations for
the certification and recordkeeping requirements for all covered
consumer products and commercial equipment. (See generally 10 CFR part
429.) The collection-of-information requirement for the certification
and recordkeeping is subject to review and approval by OMB under the
Paperwork Reduction Act (``PRA''). This requirement has been approved
by OMB under OMB control number 1910-1400. Public reporting burden for
the certification is estimated to average 35 hours per response,
including the time for reviewing instructions, searching existing data
sources, gathering and maintaining the data needed, and completing and
reviewing the collection of information. Notwithstanding any other
provision of the law, no person is required to respond to, nor shall
any person be subject to a penalty for failure to comply with, a
collection of information subject to the requirements of the PRA,
unless that collection of information displays a currently valid OMB
Control Number. This final determination, which concludes that amended
energy conservation standards for MHLFs would not be cost effective
(and by extension, not economically justified) as required under the
relevant statute, imposes no new information or recordkeeping
requirements. Accordingly, clearance from the OMB 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 implementing regulations (10 CFR part 1021). DOE
has determined that this rule qualifies for categorical exclusion A4
because it is an interpretation or ruling in regards to an existing
regulations and otherwise meets the requirements for application of a
categorical exclusion. See 10 CFR 1021.410. Therefore, DOE has
determined that promulgation of this rule 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. As this final determination does not amend
the standards for MHLFs, there is no impact on the policymaking
discretion of the States. 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
[[Page 58793]]
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.
This final 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 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.
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.
Because this final determination does not amend energy conservation
standards for MHLFs, it is not a significant energy action, nor has it
been designated as such by the Administrator at OIRA. Accordingly, DOE
has not prepared a Statement of Energy Effects on this final
determination.
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.\32\ Generation of this report involved a rigorous, formal, and
documented evaluation using objective criteria and qualified and
independent reviewers to make a judgment as to the technical/
scientific/business merit, the actual or anticipated results, and the
productivity and management effectiveness of programs and/or projects.
DOE has determined that the peer-reviewed analytical process continues
to reflect current practice, and the Department followed that process
for developing its determination in the case of the present rulemaking.

Review Report'' is available at: www.energy.gov/eere/buildings/downloads/energy-conservation-standards-rulemaking-peer-review-report-0 (June 18, 2021).

M. Congressional Notification
As required by 5 U.S.C. 801, DOE will report to Congress on the
promulgation of this final determination prior to its effective date.
The report will state that it has been determined that the final
determination is not a ``major rule'' as defined by 5 U.S.C. 804(2).
VII. Approval of the Office of the Secretary
The Secretary of Energy has approved publication of this final
determination.
