address three major topics related to
operating safely during the COVID–19
pandemic:
• Safe and Healthy Environments:
School and campus approaches to
implementing the Centers for Disease
Control and Prevention’s (CDC)
recommended mitigation strategies and
preparing for and sustaining in-person
operations safely. This includes
recommendations across all grade and
age levels of students served, with focus
both on reopening buildings for the first
time as well as keeping them open
safely.
• Providing Supports to Students:
School and campus strategies to meet
student social, emotional, mental
health, academic, financial, and other
needs, including access to food and
other basic needs. This includes a
specific focus on the most vulnerable
learners and ensuring that resources
provided by schools and campuses will
be able to connect with and meet the
needs of those disconnected from
learning.
• Teacher, Faculty, and Staff WellBeing, Professional Development, and
Supports: School and campus strategies
to address the social, emotional, health,
and other needs of teachers, faculty, and
staff.

Decision and Order
In
accordance with § 431.401(f)(2) of Title
10 of the Code of Federal Regulations
(10 CFR 431.401(f)(2)), DOE gives
notification of the issuance of its
Decision and Order as set forth below.
The Decision and Order grants HTPG a
waiver from the applicable test
procedure at 10 CFR part 431, subpart
R, appendix C for specified basic
models of CO2 direct expansion unit
coolers, and provides that HTPG must
test and rate such CO2 direct expansion
unit coolers using the alternate test
procedure specified in the Decision and
Order. HTPG’s representations
concerning the energy efficiency of the
specified basic models must be based on
testing according to the provisions and
restrictions in the alternate test
procedure set forth in the Decision and
Order, and the representations must
fairly disclose the test results.
Distributors, retailers, and private
labelers are held to the same
requirements when making
representations regarding the energy
efficiency of this equipment. (42 U.S.C.
6314(d))
Consistent with 10 CFR 431.401(j),
not later than May 18, 2021, any
manufacturer currently distributing in
commerce in the United States CO2
direct expansion unit coolers employing
a technology or characteristic that
results in the same need for a waiver
from the applicable test procedure must
submit a petition for waiver.
Manufacturers not currently distributing
such products/equipment in commerce
in the United States must petition for
and be granted a waiver prior to the
distribution in commerce of CO2 direct
expansion unit coolers in the United
States. 10 CFR 431.401(j). Manufacturers
may also submit a request for interim
waiver pursuant to the requirements of
10 CFR 431.401.

SUPPLEMENTARY INFORMATION:
VerDate Sep<11>2014

Jkt 253001
I. Background and Authority
The Energy Policy and Conservation
Act, as amended (‘‘EPCA’’),1 authorizes
the U.S. Department of Energy (‘‘DOE’’)
to regulate the energy efficiency of a
number of consumer products and
certain industrial equipment. (42 U.S.C.
6291–6317) Title III, Part C 2 of EPCA
established the Energy Conservation
Program for Certain Industrial
Equipment, which sets forth a variety of
provisions designed to improve energy
efficiency for certain types of industrial
equipment. This equipment includes
walk-in cooler and walk-in freezer
(collectively, ‘‘walk-in’’) refrigeration
systems, the focus of this document. (42
U.S.C. 6311(1)(G))
The energy conservation program
under EPCA consists essentially of four
parts: (1) Testing, (2) labeling, (3)
Federal energy conservation standards,
and (4) certification and enforcement
procedures. Relevant provisions of
EPCA include definitions (42 U.S.C.
6311), test procedures (42 U.S.C. 6314),
labeling provisions (42 U.S.C. 6315),
energy conservation standards (42
U.S.C. 6313), and the authority to
require information and reports from
manufacturers (42 U.S.C. 6316).
The Federal testing requirements
consist of test procedures that
manufacturers of covered equipment
must use as the basis for: (1) Certifying
to DOE that their equipment complies
with the applicable energy conservation
standards adopted pursuant to EPCA (42
U.S.C. 6316(a); 42 U.S.C. 6295(s)), and
(2) making representations about the
efficiency of that equipment (42 U.S.C.
6314(d)). Similarly, DOE must use these
test procedures to determine whether
the equipment complies with relevant
standards promulgated under EPCA. (42
U.S.C. 6316(a); 42 U.S.C. 6295(s))
Under 42 U.S.C. 6314, EPCA sets forth
the criteria and procedures DOE is
required to follow when prescribing or
amending test procedures for covered
equipment. EPCA requires that any test
procedures prescribed or amended
under this section must be reasonably
designed to produce test results which
reflect energy efficiency, energy use or
estimated annual operating cost of
covered equipment during a
representative average use cycle and
requires that test procedures not be
unduly burdensome to conduct. (42
1 All references to EPCA in this document refer
to the statute as amended through the Energy Act
of 2020, Public Law 116–260 (Dec. 27, 2020).
2 For editorial reasons, upon codification in the
U.S. Code, Part C was redesignated as Part A–1.

U.S.C.6314(a)(2)) The test procedure for
walk-in refrigeration systems is set forth
in the Code of Federal Regulations
(‘‘CFR’’) at 10 CFR part 431, subpart R,
appendix C, Uniform Test Method for
the Measurement of Net Capacity and
AWEF of Walk-In Cooler and Walk-In
Freezer Refrigeration Systems
(‘‘Appendix C’’).
Any interested person may submit a
petition for waiver from DOE’s test
procedure requirements. 10 CFR
431.401(a)(1). DOE will grant a waiver
from the test procedure requirements if
DOE determines either that the basic
model(s) for which the waiver was
requested contains a design
characteristic that prevents testing of the
basic model according to the prescribed
test procedures, or that the prescribed
test procedures evaluate the basic model
in a manner so unrepresentative of its
true energy consumption characteristics
as to provide materially inaccurate
comparative data. 10 CFR 431.401(f)(2).
DOE may grant the waiver subject to
conditions, including adherence to
alternate test procedures. Id.
As soon as practicable after the
granting of any waiver, DOE will
publish in the Federal Register a notice
of proposed rulemaking to amend its
regulations so as to eliminate any need
for the continuation of such waiver. 10
CFR 431.401(l). As soon thereafter as
practicable, DOE will publish in the
Federal Register a final rule to that
effect. Id. When DOE amends the test
procedure to address the issues
presented in a waiver, the waiver will
automatically terminate on the date on
which use of that test procedure is
required to demonstrate compliance. 10
CFR 431.401(h)((3).
II. HTPG’s Petition for Waiver:
Assertions and Determinations
By letter dated July 6, 2020, HTPG
filed a petition for waiver and a petition
for interim waiver from the DOE test
procedure applicable to CO2 direct
expansion unit coolers set forth in
Appendix C. HTPG claimed that the test
conditions described in the AirConditioning, Heating, and Refrigeration
Institute (‘‘AHRI’’) Standard 1250–2009,
Standard for Performance Rating of
Walk-In Coolers and Freezers (‘‘AHRI
1250–2009’’) (for walk-in refrigerator
unit coolers and freezer unit coolers
tested alone), as incorporated by
Appendix C with modification, cannot
be achieved by the specified basic
models and are not consistent with
operation of HTPG’s CO2 direct
expansion unit coolers. HTPG asserted
that the prescribed test procedure is not
appropriate for HTPG’s CO2 direct
expansion unit coolers and the test
E:\FR\FM\19MRN1.SGM
19MRN1
Federal Register / Vol. 86, No. 52 / Friday, March 19, 2021 / Notices
conditions are not achievable, since
CO2 refrigerant has a critical
temperature of 87.8 °F 3 and the current
DOE test procedure requires a liquid
inlet saturation temperature of 105 °F
and liquid inlet subcooling of 9 °F.
HTPG suggested that the test conditions
should be more consistent with typical
operating conditions for a transcritical
CO2 booster system.
HTPG’s suggested test procedure
specifies using modified liquid inlet
saturation and liquid inlet subcooling
temperatures of 38 °F and 5 °F,
respectively, for both walk-in
refrigerator unit coolers and walk-in
freezer unit coolers. Additionally,
because the subject units are used in
transcritical CO2 booster systems, HTPG
recommended that the calculations in
AHRI 1250–2009, section 7.9 should be
used to determine the annual walk-in
energy factor (‘‘AWEF’’) and net
capacity for unit coolers matched to
parallel rack systems, as required under
the DOE test procedure. This section of
AHRI 1250–2009 is prescribed by the
DOE test procedure for determining
AWEF for all unit coolers tested alone
(see section 3.3.1 of Appendix C).
Finally, HTPG also recommended that
AHRI 1250–2009, Table 17, EER for
Remote Commercial Refrigerated
Display Merchandisers and Storage
Cabinets, should be used to determine
power consumption of CO2 direct
expansion unit cooler systems, as
required under the DOE test procedure.
On December 23, 2020, DOE
published a notification that announced
its receipt of the petition for waiver and
granted HTPG an interim waiver. 85 FR
83927 (‘‘Notification of Petition for
Waiver’’). In the Notification of Petition
for Waiver, DOE acknowledged the
difference in critical pressure and
temperature between traditional
refrigerants (such as R404A) and CO2 as
used in HTPG’s direct expansion unit
coolers. 85 FR 83927, 83929. DOE also
noted that the transcritical nature of
CO2 generally requires a more complex
refrigeration cycle design to approach
the efficiency of traditional refrigerant
cycles during operation in high
temperature conditions. Id.
In the Notification of Petition for
Waiver, DOE also solicited comments
from interested parties on all aspects of
the petition and the specified alternate
test procedure. 85 FR 83927, 83827.
DOE received no substantive
comments 4 in response to the
Notification of Petition for Waiver.
For the reasons explained here and in
the Notification of Petition for Waiver,
absent a waiver, the basic models
identified by HTPG in its petition
cannot be tested and rated for energy
consumption on a basis representative
of their true energy consumption
characteristics. DOE has reviewed the
recommended procedure suggested by
HTPG and concludes that it will allow
for the accurate measurement of the
energy use of the CO2 direct expansion
unit coolers, while alleviating the
testing issues associated with HTPG’s
implementation of DOE’s applicable
walk-in refrigeration systems test
procedure for the specified basic
models.
Thus, DOE is requiring that HTPG test
and rate specified CO2 direct expansion
unit cooler basic models according to
the alternate test procedure specified in
this Decision and Order, which is
identical to the procedure provided in
the interim waiver.
This Decision and Order applies only
to the basic models listed and does not
extend to any other basic models. DOE
evaluates and grants waivers for only
those basic models specifically set out
14889
in the petition, not future models that
may be manufactured by the petitioner.
HTPG may request that DOE extend the
scope of this waiver to include
additional basic models that employ the
same technology as those listed in this
waiver. 10 CFR 431.401(g). HTPG may
also submit another petition for waiver
from the test procedure for additional
basic models that employ a different
technology and meet the criteria for test
procedure waivers. 10 CFR
431.401(a)(1).
DOE notes that it may modify or
rescind the waiver at any time upon
DOE’s determination that the factual
basis underlying the petition for waiver
is incorrect, or upon a determination
that the results from the alternate test
procedure are unrepresentative of the
basic models’ true energy consumption
characteristics. 10 CFR 431.401(k)(1).
Likewise, HTPG may request that DOE
rescind or modify the waiver if the
company discovers an error in the
information provided to DOE as part of
its petition, determines that the waiver
is no longer needed, or for other
appropriate reasons. 10 CFR
431.401(k)(2).
III. Order
After careful consideration of all the
material that was submitted by HTPG,
HTPG’s consumer-facing materials,
including websites and product
specification sheets for the basic models
listed in HTPG’s petition, as well as
other industry information pertaining to
the subject basic models listed by
HTPG, it is ordered that:
(1) HTPG must, as of the date of
publication of this Order in the Federal
Register, test and rate the following CO2
direct expansion unit cooler basic
models with the alternate test procedure
as set forth in paragraph (2):

[Case Number 2020-009; EERE-2020-BT-WAV-0025]
Energy Conservation Program: Decision and Order Granting a Waiver
to Heat Transfer Products Group from the Department of Energy Walk-in
Coolers and Walk-In Freezers Test Procedure
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Notification of decision and order.
-----------------------------------------------------------------------
SUMMARY: The U.S. Department of Energy (``DOE'') gives notification of
a Decision and Order (Case Number 2020-009) that grants to Heat
Transfer Products Group (``HTPG'') a waiver from specified portions of
the DOE test procedure for determining the energy efficiency of
specified carbon dioxide (``CO2'') direct expansion unit coolers. Under
the Decision and Order, HTPG is required to test and rate the specified
basic models of its CO2 direct expansion unit coolers in accordance
with the alternate test procedure set forth in the Decision and Order.
DATES: The Decision and Order is effective on March 19, 2021. The
Decision and Order will terminate upon the compliance date of any
future amendment to the test procedure for walk-in refrigeration
systems located at title 10 of the Code of Federal Regulations
(``CFR''), part 431, subpart R, appendix C that addresses the issues
presented in this waiver. At such time, HTPG must use the relevant test
procedure for these CO2 direct expansion unit coolers for any testing
to demonstrate compliance with the applicable standards, and any other
representations of energy use.

SUPPLEMENTARY INFORMATION: In accordance with Sec. 431.401(f)(2) of
Title 10 of the Code of Federal Regulations (10 CFR 431.401(f)(2)), DOE
gives notification of the issuance of its Decision and Order as set
forth below. The Decision and Order grants HTPG a waiver from the
applicable test procedure at 10 CFR part 431, subpart R, appendix C for
specified basic models of CO2 direct expansion unit coolers, and
provides that HTPG must test and rate such CO2 direct expansion unit
coolers using the alternate test procedure specified in the Decision
and Order. HTPG's representations concerning the energy efficiency of
the specified basic models must be based on testing according to the
provisions and restrictions in the alternate test procedure set forth
in the Decision and Order, and the representations must fairly disclose
the test results. Distributors, retailers, and private labelers are
held to the same requirements when making representations regarding the
energy efficiency of this equipment. (42 U.S.C. 6314(d))
Consistent with 10 CFR 431.401(j), not later than May 18, 2021, any
manufacturer currently distributing in commerce in the United States
CO2 direct expansion unit coolers employing a technology or
characteristic that results in the same need for a waiver from the
applicable test procedure must submit a petition for waiver.
Manufacturers not currently distributing such products/equipment in
commerce in the United States must petition for and be granted a waiver
prior to the distribution in commerce of CO2 direct expansion unit
coolers in the United States. 10 CFR 431.401(j). Manufacturers may also
submit a request for interim waiver pursuant to the requirements of 10
CFR 431.401.
Case # 2020-009
Decision and Order
I. Background and Authority
The Energy Policy and Conservation Act, as amended (``EPCA''),\1\
authorizes the U.S. Department of Energy (``DOE'') to regulate the
energy efficiency of a number of consumer products and certain
industrial equipment. (42 U.S.C. 6291-6317) Title III, Part C \2\ of
EPCA established the Energy Conservation Program for Certain Industrial
Equipment, which sets forth a variety of provisions designed to improve
energy efficiency for certain types of industrial equipment. This
equipment includes walk-in cooler and walk-in freezer (collectively,
``walk-in'') refrigeration systems, the focus of this document. (42
U.S.C. 6311(1)(G))
---------------------------------------------------------------------------
\1\ All references to EPCA in this document refer to the statute
as amended through the Energy Act of 2020, Public Law 116-260 (Dec.
27, 2020).
\2\ For editorial reasons, upon codification in the U.S. Code,
Part C was redesignated as Part A-1.
---------------------------------------------------------------------------
The energy conservation program under EPCA consists essentially of
four parts: (1) Testing, (2) labeling, (3) Federal energy conservation
standards, and (4) certification and enforcement procedures. Relevant
provisions of EPCA include definitions (42 U.S.C. 6311), test
procedures (42 U.S.C. 6314), labeling provisions (42 U.S.C. 6315),
energy conservation standards (42 U.S.C. 6313), and the authority to
require information and reports from manufacturers (42 U.S.C. 6316).
The Federal testing requirements consist of test procedures that
manufacturers of covered equipment must use as the basis for: (1)
Certifying to DOE that their equipment complies with the applicable
energy conservation standards adopted pursuant to EPCA (42 U.S.C.
6316(a); 42 U.S.C. 6295(s)), and (2) making representations about the
efficiency of that equipment (42 U.S.C. 6314(d)). Similarly, DOE must
use these test procedures to determine whether the equipment complies
with relevant standards promulgated under EPCA. (42 U.S.C. 6316(a); 42
U.S.C. 6295(s))
Under 42 U.S.C. 6314, EPCA sets forth the criteria and procedures
DOE is required to follow when prescribing or amending test procedures
for covered equipment. EPCA requires that any test procedures
prescribed or amended under this section must be reasonably designed to
produce test results which reflect energy efficiency, energy use or
estimated annual operating cost of covered equipment during a
representative average use cycle and requires that test procedures not
be unduly burdensome to conduct. (42 U.S.C.6314(a)(2)) The test
procedure for walk-in refrigeration systems is set forth in the Code of
Federal Regulations (``CFR'') at 10 CFR part 431, subpart R, appendix
C, Uniform Test Method for the Measurement of Net Capacity and AWEF of
Walk-In Cooler and Walk-In Freezer Refrigeration Systems (``Appendix
C'').
Any interested person may submit a petition for waiver from DOE's
test procedure requirements. 10 CFR 431.401(a)(1). DOE will grant a
waiver from the test procedure requirements if DOE determines either
that the basic model(s) for which the waiver was requested contains a
design characteristic that prevents testing of the basic model
according to the prescribed test procedures, or that the prescribed
test procedures evaluate the basic model in a manner so
unrepresentative of its true energy consumption characteristics as to
provide materially inaccurate comparative data. 10 CFR 431.401(f)(2).
DOE may grant the waiver subject to conditions, including adherence to
alternate test procedures. Id.
As soon as practicable after the granting of any waiver, DOE will
publish in the Federal Register a notice of proposed rulemaking to
amend its regulations so as to eliminate any need for the continuation
of such waiver. 10 CFR 431.401(l). As soon thereafter as practicable,
DOE will publish in the Federal Register a final rule to that effect.
Id. When DOE amends the test procedure to address the issues presented
in a waiver, the waiver will automatically terminate on the date on
which use of that test procedure is required to demonstrate compliance.
10 CFR 431.401(h)((3).
II. HTPG's Petition for Waiver: Assertions and Determinations
By letter dated July 6, 2020, HTPG filed a petition for waiver and
a petition for interim waiver from the DOE test procedure applicable to
CO2 direct expansion unit coolers set forth in Appendix C. HTPG claimed
that the test conditions described in the Air-Conditioning, Heating,
and Refrigeration Institute (``AHRI'') Standard 1250-2009, Standard for
Performance Rating of Walk-In Coolers and Freezers (``AHRI 1250-2009'')
(for walk-in refrigerator unit coolers and freezer unit coolers tested
alone), as incorporated by Appendix C with modification, cannot be
achieved by the specified basic models and are not consistent with
operation of HTPG's CO2 direct expansion unit coolers. HTPG asserted
that the prescribed test procedure is not appropriate for HTPG's CO2
direct expansion unit coolers and the test
[[Page 14889]]
conditions are not achievable, since CO2 refrigerant has a critical
temperature of 87.8 [deg]F \3\ and the current DOE test procedure
requires a liquid inlet saturation temperature of 105 [deg]F and liquid
inlet subcooling of 9 [deg]F. HTPG suggested that the test conditions
should be more consistent with typical operating conditions for a
transcritical CO2 booster system.
---------------------------------------------------------------------------
\3\ The test procedure specifies the unit cooler refrigerant
inlet condition in terms of a saturation temperature (the
temperature at which it completes the condensation process in a
condenser) and the subcooling temperature (additional reduction in
temperature lower than the specified saturation temperature). For
CO2, the critical temperature above which there cannot exist
separate liquid and gas phases is below the saturation condition
specified in the test procedure--hence, the specified condition
cannot be achieved.
---------------------------------------------------------------------------
HTPG's suggested test procedure specifies using modified liquid
inlet saturation and liquid inlet subcooling temperatures of 38 [deg]F
and 5 [deg]F, respectively, for both walk-in refrigerator unit coolers
and walk-in freezer unit coolers. Additionally, because the subject
units are used in transcritical CO2 booster systems, HTPG recommended
that the calculations in AHRI 1250-2009, section 7.9 should be used to
determine the annual walk-in energy factor (``AWEF'') and net capacity
for unit coolers matched to parallel rack systems, as required under
the DOE test procedure. This section of AHRI 1250-2009 is prescribed by
the DOE test procedure for determining AWEF for all unit coolers tested
alone (see section 3.3.1 of Appendix C). Finally, HTPG also recommended
that AHRI 1250-2009, Table 17, EER for Remote Commercial Refrigerated
Display Merchandisers and Storage Cabinets, should be used to determine
power consumption of CO2 direct expansion unit cooler systems, as
required under the DOE test procedure.
On December 23, 2020, DOE published a notification that announced
its receipt of the petition for waiver and granted HTPG an interim
waiver. 85 FR 83927 (``Notification of Petition for Waiver''). In the
Notification of Petition for Waiver, DOE acknowledged the difference in
critical pressure and temperature between traditional refrigerants
(such as R404A) and CO2 as used in HTPG's direct expansion unit
coolers. 85 FR 83927, 83929. DOE also noted that the transcritical
nature of CO2 generally requires a more complex refrigeration cycle
design to approach the efficiency of traditional refrigerant cycles
during operation in high temperature conditions. Id.
In the Notification of Petition for Waiver, DOE also solicited
comments from interested parties on all aspects of the petition and the
specified alternate test procedure. 85 FR 83927, 83827. DOE received no
substantive comments \4\ in response to the Notification of Petition
for Waiver.
---------------------------------------------------------------------------
\4\ One comment was received, but it did not contain any
content. The comment only stated the docket number for the
notification of petition for waiver and grant of an interim waiver.
---------------------------------------------------------------------------
For the reasons explained here and in the Notification of Petition
for Waiver, absent a waiver, the basic models identified by HTPG in its
petition cannot be tested and rated for energy consumption on a basis
representative of their true energy consumption characteristics. DOE
has reviewed the recommended procedure suggested by HTPG and concludes
that it will allow for the accurate measurement of the energy use of
the CO2 direct expansion unit coolers, while alleviating the testing
issues associated with HTPG's implementation of DOE's applicable walk-
in refrigeration systems test procedure for the specified basic models.
Thus, DOE is requiring that HTPG test and rate specified CO2 direct
expansion unit cooler basic models according to the alternate test
procedure specified in this Decision and Order, which is identical to
the procedure provided in the interim waiver.
This Decision and Order applies only to the basic models listed and
does not extend to any other basic models. DOE evaluates and grants
waivers for only those basic models specifically set out in the
petition, not future models that may be manufactured by the petitioner.
HTPG may request that DOE extend the scope of this waiver to include
additional basic models that employ the same technology as those listed
in this waiver. 10 CFR 431.401(g). HTPG may also submit another
petition for waiver from the test procedure for additional basic models
that employ a different technology and meet the criteria for test
procedure waivers. 10 CFR 431.401(a)(1).
DOE notes that it may modify or rescind the waiver at any time upon
DOE's determination that the factual basis underlying the petition for
waiver is incorrect, or upon a determination that the results from the
alternate test procedure are unrepresentative of the basic models' true
energy consumption characteristics. 10 CFR 431.401(k)(1). Likewise,
HTPG may request that DOE rescind or modify the waiver if the company
discovers an error in the information provided to DOE as part of its
petition, determines that the waiver is no longer needed, or for other
appropriate reasons. 10 CFR 431.401(k)(2).
III. Order
After careful consideration of all the material that was submitted
by HTPG, HTPG's consumer-facing materials, including websites and
product specification sheets for the basic models listed in HTPG's
petition, as well as other industry information pertaining to the
subject basic models listed by HTPG, it is ordered that:
(1) HTPG must, as of the date of publication of this Order in the
Federal Register, test and rate the following CO2 direct expansion unit
cooler basic models with the alternate test procedure as set forth in
paragraph (2):

(2) The alternate test procedure for the HTPG basic models listed
in paragraph (1) of this Order is the test procedure for walk-in
refrigeration systems prescribed by DOE at 10 CFR part 431, subpart R,
appendix C (``Appendix C''), except that the liquid inlet saturation
temperature test condition and liquid inlet subcooling temperature test
condition shall be modified to 38 [deg]F and 5 [deg]F, respectively,
for both walk-in refrigerator unit coolers and walk-in freezer unit
coolers, as detailed below. All other requirements of Appendix C and
DOE's other relevant regulations remain applicable.
In Appendix C, under section 3.1. General modifications: Test
Conditions and Tolerances, revise section 3.1.5., to read as follows:
3.1.5. Tables 15 and 16 shall be modified to read as follows:

(3) Representations. HTPG may not make representations about the
energy efficiency of a basic model listed in paragraph (1) of this
Order for compliance or marketing, unless the basic model has been
tested in accordance with the provisions set forth above and such
representations fairly disclose the results of such testing.
(4) This waiver shall remain in effect according to the provisions
of 10 CFR 431.401.
(5) DOE issues this waiver on the condition that the statements,
representations, and information provided by HTPG are valid. If HTPG
makes any modifications to the controls or configurations of these
basic models, such modifications will render the waiver invalid with
respect to that basic model, and HTPG will either be required to use
the current Federal test method or submit a new application for a test
procedure waiver. DOE may rescind or modify this waiver at any time if
it determines the factual basis underlying the petition for waiver is
incorrect, or the results from the alternate test procedure are
unrepresentative of a basic model's true energy consumption
characteristics. 10 CFR 431.401(k)(1). Likewise, HTPG may request that
DOE rescind or modify the waiver if HTPG discovers an error in the
information provided to DOE as part of its petition, determines that
the waiver is no longer needed, or for other appropriate reasons. 10
CFR 431.401(k)(2).
(6) HTPG remains obligated to fulfill any applicable requirements
set forth at 10 CFR part 429.
