SUMMARY: The Department of Energy (DOE) is amending its test procedures 
for battery chargers (BCs) and external power supplies (EPSs) to 
include provisions for measuring standby mode and off mode energy 
consumption, as directed by the Energy Independence and Security Act of 
2007 (EISA 2007). Furthermore, DOE is adding to its single-voltage 
external power supply test procedure specifications for testing switch-
selectable external power supplies. Finally, DOE is extending the 
current certification reporting requirements to the Class A external 
power supplies for which Congress established energy efficiency 
standards in EISA 2007.

DATES: This rule is effective April 27, 2009. The incorporation by 
reference of certain publications listed in the rule is approved by the 
Director of the Federal Register on April 27, 2009.

I. Background and Legal Authority

    Title III of the Energy Policy and Conservation Act, as amended (42 
U.S.C. 6291 et seq.; EPCA) sets forth a variety of provisions designed 
to improve energy efficiency. Part A \1\ of title III (42 U.S.C. 6291-
6309) establishes the ``Energy Conservation Program for Consumer 
Products Other Than Automobiles.'' The consumer (``covered products'') 
currently subject to this program include battery chargers and external 
power supplies (referred to respectively as ``BCs'' and ``EPSs''). 
Manufacturers of covered products are required to use the relevant DOE 
test procedures to certify compliance with the energy conservation 
standards adopted under EPCA.
---------------------------------------------------------------------------

    \1\ This part was originally titled Part B; however, it was 
redesignated Part A after Part B was repealed by Public Law 109-58.
---------------------------------------------------------------------------

    Section 323(b) of EPCA authorizes DOE to amend or establish new 
test procedures as appropriate for each of the covered products. (42 
U.S.C. 6293(b)) This section provides that ``[a]ny test procedures 
prescribed or amended under this section shall be reasonably designed 
to produce test results which measure energy efficiency, energy use, 
water use (in the case of showerheads, faucets, water closets and 
urinals), or estimated annual operating cost of a covered product 
during a representative average use cycle or period of use, as 
determined by the Secretary [of Energy], and shall not be unduly 
burdensome to conduct.'' (42 U.S.C. 6293(b)(3)) In addition, EPCA 
states that DOE ``shall determine, in the rulemaking carried out with 
respect to prescribing such procedure, to what extent, if any, the 
proposed test procedure would alter the measured energy efficiency, 
measured energy use, or measured water use of any covered product as 
determined under the existing test procedure.'' (42 U.S.C. 6293(e)(1))
    Of particular relevance to the present test procedure rulemaking, 
section 135 of the Energy Policy Act of 2005 (EPACT), Public Law 109-
58, amended sections 321 and 325 of EPCA by providing definitions for 
BCs and EPSs and directing the Secretary to prescribe ``definitions and 
test procedures for the power use of battery chargers and external 
power supplies.'' (42 U.S.C. 6295(u)(1)(A)) DOE complied with this 
requirement by publishing a test procedure final rule, 71 FR 71340, on 
December 8, 2006, which included definitions and test procedures for 
BCs and EPSs. DOE codified the test procedure for BCs in appendix Y to 
subpart B of part 430 in title 10 of the Code of Federal Regulations 
(CFR) (``Uniform Test Method for Measuring the Energy Consumption of 
Battery Chargers'') and the test procedure for EPSs in appendix Z to 
subpart B of 10 CFR part 430 (``Uniform Test Method for Measuring the 
Energy Consumption of External Power Supplies'').
    On December 19, 2007, the Energy Independence and Security Act of 
2007 (EISA 2007), Public Law 110-140, amended sections 321, 323, and 
325 of EPCA, prompting DOE to propose amendments to its test procedures 
for BCs and EPSs. These amendments were published in the August 15, 
2008, notice of proposed rulemaking (NOPR), 73 FR 48054.
    Section 301 of EISA 2007 amended section 321 of EPCA by modifying 
definitions concerning EPSs. EPACT had amended EPCA to define an EPS as 
``an external power supply circuit that is used to convert household 
electric current into DC current or lower-voltage AC current to operate 
a consumer product.'' \2\ (42 U.S.C. 6291(36)(A)) Section 301 of EISA 
2007 further amended this definition by creating a subset of EPSs 
called Class A External Power Supplies. EISA 2007 defined this subset 
as those EPSs that, in addition to meeting several other requirements 
common to all EPSs,\3\ are ``able to convert to only 1 AC or DC output 
voltage at a time'' and have ``nameplate output power that is less than 
or equal to 250 watts.'' (42 U.S.C. 6291(36)(C)(i)) Section 301 also 
amended EPCA to establish minimum standards for these products, which 
became effective on July 1, 2008 (42 U.S.C. 6295(u)(3)(A)), and 
directed DOE to publish a final rule by July 1, 2011, to determine 
whether to amend these energy conservation

[[Page 13320]]

standards for EPSs. (42 U.S.C. 6295(u)(3)(D))
---------------------------------------------------------------------------

    \2\ The terms ``AC'' and ``DC'' refer to the polarity (i.e., 
direction) and amplitude of current and voltage associated with 
electrical power. For example, a household wall socket supplies 
alternating current (AC), which varies in amplitude and reverses 
polarity. In contrast, a battery or solar cell supplies direct 
current (DC), which is constant in both amplitude and polarity.
    \3\ The full EISA 2007 definition of a class A external power 
supply includes a device that ``(I) is designed to convert line 
voltage AC input into lower voltage AC or DC output; (II) is able to 
convert to only 1 AC or DC output voltage at a time; (III) is sold 
with, or intended to be used with, a separate end-use product that 
constitutes the primary load; (IV) is contained in a separate 
physical enclosure from the end-use product; (V) is connected to the 
end-use product via a removable or hard-wired male/female electrical 
connection, cable, cord, or other wiring; and (VI) has nameplate 
output power that is less than or equal to 250 watts.'' (42 U.S.C. 
6291(36)(C)(i)).
---------------------------------------------------------------------------

    In addition, section 309 of EISA 2007 amended section 325(u)(1)(E) 
of EPCA, instructing DOE to issue ``a final rule that determines 
whether energy conservation standards shall be issued for external 
power supplies or classes of external power supplies.'' (42 U.S.C. 
6295(u)(1)(E)(i)(I)) As explained in the August 15, 2008, NOPR, DOE 
interpreted this section as a requirement to determine by December 19, 
2009, whether energy conservation standards shall be issued for non-
Class A EPSs. See 73 FR 48054, 48056.
    Section 310 of EISA 2007 amended section 325 of EPCA to establish 
definitions for active mode, standby mode, and off mode. This section 
also directed DOE to amend its existing test procedures by December 31, 
2008, to measure the energy consumed in standby mode and off mode for 
both BCs and EPSs. Further, it authorized the Department to amend, by 

rule, any of the definitions for active, standby, and off mode as long 
as the Department takes into consideration the most current versions of 
Standards 62301 (``Household Electrical Appliances--Measurement of 
Standby Power'') and 62087 (``Methods of Measurement for the Power 
Consumption of Audio, Video and Related Equipment'') of the 
International Electrotechnical Commission (IEC). (See EPCA, section 
325(gg)(2)(A), codified at 42 U.S.C. 6295(gg)(2)(A).)
    DOE's proposals were presented and explained at a public meeting on 
September 12, 2008. DOE invited written comments, data, and information 
on the NOPR and accepted such material through October 29, 2008.

II. Summary of the Final Rule

    In this final rule, DOE is modifying the current test procedures 
for BCs and EPSs. The amendments achieve the following objectives:
    (1) Address the statutory requirement to expand test procedures to 
incorporate measurement of standby mode and off mode energy consumption 
for BCs and single-voltage EPSs, including switch-selectable single-
voltage EPSs;
    (2) Clarify the existing single-voltage EPS test procedure by 
revising existing definitions and adopting new ones; and
    (3) Incorporate certification requirements for EPSs subject to 
minimum efficiency standards effective July 1, 2008.

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

    DOE believes that today's amendments neither alter the measured 
energy efficiency of the tested products nor add any burden on the 
industry because the changes only (1) clarify existing test procedures 
or (2) insert test procedures for modes that are not regulated by 
standards. Thus, DOE is amending its test procedures as summarized in 
the following sections.

A. Standby Mode and Off Mode Definitions and Test Procedures

    As explained in the August 15, 2008, NOPR, the standby and off mode 
definitions created by EISA 2007 do not apply to all BCs and EPSs. 
Therefore, following the requisite consideration of IEC standards 
62301\4\ and 62087,\5\ DOE proposed amended definitions.
---------------------------------------------------------------------------

    \4\ IEC 62301, ``Household Electrical Appliances--Measurement of 
Standby Power,'' International Electrotechnical Commission, First 
edition, June 2005.
    \5\ IEC 62087, ``Methods of Measurement for the Power 
Consumption of Audio, Video and Related Equipment,'' International 
Electrotechnical Commission, Second edition, October 2008.
---------------------------------------------------------------------------

    In today's final rule, DOE (1) adopts amended definitions of 
standby mode and off mode for BCs and EPSs, (2) revises the test 
procedures to measure standby mode and off mode energy consumption for 
BCs and EPSs; and (3) includes a definition of a ``manual on-off 
switch'' to clarify the application of the above test procedures. A 
detailed discussion of the definitions and test procedures for standby 
and off mode can be found in sections III.A and III.B below.

B. Clarification of Test Procedure Definitions

    In the August 15, 2008, NOPR, DOE proposed amendments to the 
definitions to improve the clarity of the existing test procedures. 
Through written and oral comments, stakeholders suggested additional 
clarifications to the definitions. Accordingly, in today's final rule, 
DOE is modifying the definitions of numerous terms, listed in Table 1. 
A detailed discussion of these definitions can be found in section 
III.C.

C. Switch-Selectable Single-Voltage EPSs

    DOE proposed in the August 15, 2008, NOPR a method for testing 
single-voltage EPSs that incorporate a switch-selectable output 
voltage. For these EPSs, DOE proposed that testing be conducted twice: 
first with the output voltage set to the highest voltage and then with 
the output voltage set to the lowest voltage. Stakeholders did not 
oppose this proposal; therefore, DOE is including it in this final 
rule. Section III.D provides a brief discussion of testing requirements 
for switch-selectable EPSs.

D. Certification Requirements for EPSs

    Manufacturers of covered and regulated products must report to DOE 
that the products they manufacture comply with applicable energy 
conservation standards. To demonstrate compliance with EISA 2007 
standards for Class A EPSs manufacturers must: (1) Select a 
representative sample of units, (2) test them according to the DOE test 
procedure, and (3) certify the compliance of the EPS model(s) based on 
the test results of the sample.
    DOE proposed sampling requirements for BCs and EPSs on July 25, 
2006. 71 FR 42178, 42204. While some of the provisions from that 
proposal were finalized in the December 8, 2006, final rule, 71 FR 
71340, the sampling requirements are in the process of being finalized 
in a separate rulemaking proceeding. Manufacturers are not required to 
certify compliance with EISA 2007 standards to DOE until these sampling 
requirements are finalized; however, manufacturers are required to be 
in compliance with the standards.
    DOE also proposed test procedures for measuring the energy 
efficiency of BCs (appendix Y) and EPSs (appendix Z) in the July 25, 
2006, NOPR. 71 FR 42178, 42206-42207. These were finalized in the 
December 8, 2006, final rule, 71 FR 71340, 71368. Amendments to these 
test procedures are discussed in sections III.A, III.B, III.C, and 
III.D.
    Finally, DOE proposed definitions of ``basic model'' and ``covered 
product'' as they apply to BCs and EPSs in the July 25, 2006, NOPR. 71 
FR 42178, 42203. The December 8, 2006, final rule inserted these 
definitions into 10 CFR 430.2. 71 FR 71340, 71365-71366. However, 
because of the absence of standards, DOE did not propose certification 
requirements for EPSs or BCs in the July 25, 2006 NOPR. Following the 
passage of EISA 2007 on December 19, 2007, and the establishment of 
mandatory standards for Class A EPSs, DOE proposed certification 
requirements for Class A EPSs in the August 15, 2008, NOPR. 73 FR 
48054, 48072-48076. In addition, DOE considered an alternate 
methodology by which manufacturers would certify the compliance of each 
basic model, but only submit test results for the highest- and lowest-
voltage basic models within a design family (i.e., a group of similar 
models that differ only by output voltage). 73 FR 48054, 48073-48074 
(August 15, 2008). Based on stakeholder comments, DOE is including this 
methodology in today's final rule, as discussed further in section 
III.E.

E. Proposed Amendments Not Adopted in the Final Rule

    DOE also proposed several other amendments to the EPS test 
procedure. Due to the number of stakeholder comments and the limited 
timeframe for this rulemaking, DOE has decided to postpone 
consideration of these

[[Page 13322]]

proposals and exclude them from this final rule.
    The August 15, 2008, NOPR proposed to amend the EPS test procedure 
to allow for testing of multiple-voltage EPSs, a type of EPS subject to 
the non-Class A determination analysis. Because no test procedure 
currently exists to measure the efficiency or energy consumption of 
multiple-voltage EPSs, DOE developed a proposed test procedure. See 73 
FR 48054, 48064-48068 (August 15, 2008). Due to the limited time 
provided by EISA 2007 and limited resources available prior to the 
publication of this final rule, DOE was unable to address the large 
number of stakeholder comments received and decided to defer action on 
multiple-voltage EPSs to a 2009 rulemaking.
    In the August 15, 2008, NOPR, DOE also considered making limited 
changes to the test setup and measurement instructions for single-
voltage EPSs that would have been modeled on its proposed test 
procedure for multiple-voltage EPSs. These changes were intended to 
reduce the testing burden and improve the accuracy and repeatability of 
measurement by accounting for the limitations of test equipment and 
laboratory conditions. Stakeholders from environmental and consumer 
groups as well as other standard-setting organizations, however, were 
concerned that modifying the EPS single-voltage test procedure would 
undo international efforts to enact consistent test procedures and 
standards for single-voltage EPSs. Because of these negative comments, 
DOE decided to exclude any amendments affecting the measurement of 
single-voltage EPSs in active and no-load modes from this final rule.
    Lastly, this final rule does not include an active mode test 
procedure for BCs. Because DOE did not include an active mode BC test 
procedure in the August 15, 2008, NOPR, including one in this 
particular final rule would have prevented the public from having an 
opportunity to comment on this issue. (42 U.S.C. 6293(b)(3)) DOE does, 
however, intend to propose an active mode BC test procedure in 2009 and 
solicit comments to address this issue in greater detail.

III. Discussion

A. Standby Mode and Off Mode Definitions

    In the August 15, 2008, NOPR, DOE proposed that for BCs, standby 
mode (or no-load mode) \6\ is ``the condition in which (1) the battery 
charger is connected to the main electricity supply; (2) the battery is 
not connected to the charger; and (3) for battery chargers with manual 
on-off switches, all switches are turned on.'' 73 FR 48054, 48060. Off 
mode is the condition, for battery chargers with manual on-off 
switches, ``in which the battery charger is (1) connected to the main 
electricity supply; (2) is not connected to the battery; and (3) all 
switches are turned off.'' 73 FR 48054, 48061 (August 15, 2008).
---------------------------------------------------------------------------

    \6\ For BCs, the two modes were proposed to be equivalent; 
however, in the final rule, DOE is dropping the term ``no-load 
mode'' in favor of ``no-battery mode.'' For EPSs, the two modes are 
similar: standby mode is no-load mode, except with all manual on-off 
switches turned on. However, because the no-load mode test procedure 
already requires that the EPS be tested with all manual on-off 
switches turned on, the test procedure for no-load mode and standby 
mode are the same.
---------------------------------------------------------------------------

    DOE proposed similar definitions for EPSs, except that in standby 
and off modes, EPSs were to be disconnected from their loads rather 
than from a battery. DOE proposed to define standby mode to mean ``the 
condition in which the EPS is in no-load mode and, for external power 
supplies with on-off switches, all switches are turned on,'' 73 FR 
48054, 48062 (August 15, 2008), and no-load mode to mean ``the mode of 
operation when an EPS is connected to the main electricity supply and 
the output is (or ``all outputs are'' for a multiple-voltage external 
power supply) not connected to a load (or ``loads'' for a multiple-
voltage external power supply.),'' 73 FR 48054, 48062 (August 15, 
2008). DOE also proposed to define off mode as ``the condition, 
applicable only to units having on-off switches, in which the external 
power supply is (1) connected to the main electricity supply; (2) the 
output is not connected to any load; and (3) all switches are turned 
off.'' 73 FR 48054, 48063 (August 15, 2008).
    DOE received comments on three issues related to the proposed 
definitions for standby and off mode: (1) Harmonization of the standby 
and off mode definitions with international standards; (2) 
differentiation between EPS no-load mode and BC no-battery mode; and 
(3) clarification of the definition of the on-off switch used to 
distinguish standby mode from off mode for both BCs and EPSs. A 
discussion of stakeholder comments on these issues is presented below.
1. Harmonization of Standby and Off Mode Definitions
    During the test procedure public meeting held on September 12, 
2008, Microsoft recommended that DOE harmonize with standby and off 
mode definitions and test procedures proposed in the European Union. 
(Pub. Mtg. Tr., No. 17 at p. 71) \7\ Similarly, the U.S. Environmental 
Protection Agency (EPA) and the Australian Department of the 
Environment, Water, Heritage, and the Arts (Australia) commented that 
DOE should not develop a separate definition for standby mode, lest it 
interfere with a forthcoming version of IEC Standard 62301 on standby 
power measurement. (EPA, No. 31 at p. 1; Australia, No. 20 at p. 2) \8\ 
The Association of Home Appliance Manufacturers (AHAM), however, noted 
that although DOE is correct to consider IEC Standard 62301 in defining 
standby mode, it should not include it by reference, because the IEC 
standard is a ``living document'' and subject to change. (Pub. Mtg. 
Tr., No. 17 at p. 82)
---------------------------------------------------------------------------

    \7\ A notation in the form ``Pub. Mtg. Tr., No. 17 at p. 71'' 
identifies an oral comment that DOE received during the September 
12, 2008, NOPR public meeting. This comment was recorded in the 
public meeting transcript in the docket for this rulemaking (Docket 
No. EERE-2008-BT-TP-0004), maintained in the Resource Room of the 
Building Technologies Program. This particular notation refers to a 
comment (1) recorded in document number 17, which is the public 
meeting transcript filed in the docket of this rulemaking and (2) 
appearing on page 71 of document number 17.
    \8\ A notation in the form ``EPA, No. 31 at p. 1'' identifies a 
written comment that DOE has received and has included in the docket 
of this rulemaking. This particular notation refers to (1) a comment 
submitted by the Environmental Protection Agency (EPA), (2) in 
document number 31 in the docket of this rulemaking, and (3) 
appearing on page 1 of document number 37.
---------------------------------------------------------------------------

    As required by the EISA 2007 amendments to section 323 of EPCA (62 
U.S.C. 6295(gg)(B)), the proposed definitions of standby and off mode 
were developed after considering IEC Standards 62301 and 62087. 
However, as described in the August 15, 2008, NOPR, these international 
standards apply to a variety of electronic products, and do not provide 
the specific guidance necessary for repeatable measurement of BC and 
EPS standby and off mode energy consumption. Also, the differing scope 
between IEC Standard 62301 and DOE's EPS test procedure should allay 
Australia's concern with conflicts between the two. Therefore, today's 
final rule maintains the structure of the definitions and test 
procedures presented in the August 15, 2008 NOPR and does not 
incorporate IEC Standard 62301.
    The standby mode definition in today's final rule references the 
no-load mode definition, which comes from EPA's internationally 
recognized ``Test Method for Calculating the Energy Efficiency of 
Single-Voltage External AC-DC and AC-AC Power Supplies.'' \9\ 
Accordingly, the adoption

[[Page 13323]]

 of today's test procedure, which is based on EPA's internationally 
recognized protocol for EPSs, fosters continued international 
harmonization of energy efficiency testing procedures.
---------------------------------------------------------------------------

    \9\ The development of this test procedure was funded by the 
California Energy Commission's Public Interest Energy Research 
Program (PIER), and the test procedure is also known as the ``CEC 
single-voltage EPS test procedure.'' (EPA, Test Method for 
Calculating the Energy Efficiency of Single-Voltage External AC-DC 
and AC-AC Power Supplies,'' p. 1. See http://www.energystar.gov/ia/partners/prod_development/downloads/power_supplies/EPSupplyEffic_TestMethod_0804.pdf).
---------------------------------------------------------------------------

2. Differentiation Between EPS No-Load Mode and BC No-Battery Mode
    Ecos Consulting and the Power Tool Institute (PTI) and AHAM 
commented that BC ``no-load mode'' (included as an alternate name for 
``standby mode'' in the ``Definitions'' section of the BC test 
procedure, section 2 of appendix Y) was confusing and Ecos suggested 
that it be renamed to ``no-battery mode'' to avoid confusion when 
testing BCs with wall adapters. (Pub. Mtg. Tr., No. 17 at pp. 74-76)
    The amendments to the definition of BC standby mode proposed in the 
August 15, 2008, NOPR also referred to the BC mode in question as ``no 
load mode.'' 73 FR 48054, 48080. Nonetheless, DOE recognizes that using 
this term for BCs may cause unnecessary confusion. Furthermore, because 
the term ``no-load'' is used nowhere else in the existing BC test 
procedure in appendix Y, the EPA BC test procedure that it references, 
or the other amendments promulgated by today's final rule, there is no 
benefit to maintaining it in the definitions section. Therefore, DOE is 
renaming BC ``no-load mode'' to ``no-battery mode'' in the definition 
of BC standby mode. Today's final rule will insert this amended 
definition into section 2.l of appendix Y.
3. Clarification of the Definition of the On-Off Switch
    As the above discussion illustrates, the definitions for standby 
and off modes that DOE proposed in the August 15, 2008, NOPR depend on 
the state of the on-off switch used to control the BC or EPS. User-
activated on-off switches are not common in BCs and EPSs, and in their 
comments, stakeholders expressed some confusion regarding the meaning 
of the term ``on-off switch'' in the context of the standby and off 
mode definitions.
    For example, products with integral batteries typically have some 
battery charging circuits inside the products, and it may be unclear 
which switches should be turned on for standby mode testing. Because 
the on-off switches of integral battery products control end-use 
product operation and not battery charging, testers have traditionally 
turned them off while testing the BC portion of the product, so that 
end-use product power consumption is not measured in addition to BC 
power consumption. But since the definition of standby mode proposed in 
the August 15, 2008, NOPR would reverse this longstanding practice by 
asking testers to turn all on-off switches on, adopting this change 
without further clarification could create confusion for testers.
    Ecos commented that the on-off switch referenced in the definitions 
could be mistaken for an automatic switch that the user activates 
inadvertently when removing the battery. Ecos stressed that because DOE 
is introducing a new mode, it should define the on-off switch carefully 
to avoid confusion. (Pub. Mtg. Tr., No. 17 at pp. 80-81) Pacific Gas 
and Electric (PG&E) and the American Council for an Energy-Efficient 
Economy (ACEEE) also recommended that DOE provide a definition for a 
manual on-off switch and provided a sample definition. (PG&E & ACEEE, 
No. 21 at p. 2)
    ADT Security Services, Sensormatic Electronics Corporation, and 
Tyco Safety Products Canada (all three are subsidiaries of Tyco Fire & 
Security and will be referred to throughout the document as ``Tyco'') 
sought clarification about which portions of the standby mode 
definition apply to products without on-off switches (Pub. Mtg. Tr., 
No. 17 at p. 73), while Australia commented that off mode should only 
be applicable to products with an appropriately defined on-off switch. 
(Australia, No. 20 at p. 2)
    Despite these additional comments, DOE believes that the 
definitions, as proposed, are unambiguous: The off mode definitions are 
only applicable to BCs and EPSs with on-off switches, while the standby 
mode definitions are applicable to BCs and EPSs with or without on-off 
switches. The final clause of the standby mode definitions--``all 
switches are turned on''--applies only to BCs and EPSs with on-off 
switches. The only necessary clarification is an appropriately narrow 
definition of ``on-off switch'' to eliminate confusion with switches 
used to control end-use product function and automatic switches that 
are inadvertently activated by the user during battery or load 
disconnection. Therefore, in today's final rule, DOE is adopting the 
definition of ``manual on-off switch'' based on the one provided by 
PG&E and ACEEE and modifying the proposed definitions of standby and 
off mode to reference this new definition. This final rule inserts the 
definitions of manual on-off switch, off mode, and standby mode into 
sections 2.h, 2.k, and 2.l of appendix Y for BCs and sections 2.g, 2.p, 
and 2.t of appendix Z for EPSs.

B. Standby Mode and Off Mode Test Procedures

    In the August 15, 2008, NOPR, DOE proposed two new subsections for 
standby and off mode measurement under the ``Test Measurement'' section 
of the BC test procedure (section 4 of appendix Y). 73 FR 48054, 48060. 
The amendments would also insert a section for off mode measurement 
under the ``Test Measurement'' section of the EPS test procedure 
(section 4 of appendix Z). 73 FR 48054, 48062-48063 (August 15, 2008).
    The ``Test Measurement'' section of the EPS test procedure already 
included a test procedure for active mode and no-load mode measurement, 
which required testing of the EPS with ``any built-in switch in the UUT 
[unit under test] * * * in the `on' position.'' (See section 5.a of 
EPA's ``Test Method for Calculating the Energy Efficiency of Single-
Voltage External AC-DC and AC-AC Power Supplies,'' incorporated by 
reference in section 4 of appendix Z.) DOE leveraged the existing test 
procedure by proposing to define EPS standby mode as ``the condition in 
which the external power supply is in no-load mode and, for external 
power supplies with on-off switches, all switches are turned on.'' 73 
FR 48054, 48062 (August 15, 2008), and to use the no-load test 
procedure as the standby mode test procedure. 73 FR 48054, 48063 
(August 15, 2008).
    Stakeholders commented on the following issues: (1) Specifying the 
duration of the BC standby and off mode tests; (2) clarifying the BC 
standby mode test for integral-battery products; (3) obviating EPS 
standby mode testing through end-use product testing; (4) modifying the 
stability requirement for measuring EPS energy consumption; (5) 
clarifying the assessment point for AC input power into the EPS; (6) 
clarifying the disconnection point for standby mode testing for systems 
with more than two enclosures; (7) specifying and reporting the shunt 
resistance value used during EPS measurement; and (8) excluding EPSs 
that do not operate in standby or no-load modes from testing under the 
standby mode test procedure.
1. Specifying the Duration of the BC Standby and Off Mode Tests
    In the August 15, 2008, NOPR, DOE proposed a 1-hour duration for 
the BC standby and off mode energy

[[Page 13324]]

consumption measurement. However, the EPA BC test procedure--
incorporated by reference in the existing BC test procedure (sections 3 
and 4 of appendix Y) and upon which these proposed amendments were 
based--requires a 12-hour test duration in certain circumstances. DOE 
raised this issue in the August 15, 2008 NOPR, soliciting stakeholder 
comments on the appropriate duration of the standby and off mode 
measurements. 73 FR 48054, 48062.
    Ecos commented that the 12-hour option was too long and supported a 
test duration of 1 hour as necessary to ``achieve a measure of thermal 
stability'' and to ensure repeatability of measurements. (Pub. Mtg. 
Tr., No. 17 at p. 98) Hewlett-Packard (HP) and the Information 
Technology Industry Council (ITI), however, commented that a test 
duration of 1 hour is unnecessarily long and will result in higher 
testing costs than necessary. According to ITI, tests can be conducted 
in as little as 10 seconds using modern measurement equipment, and 
warmup could be performed prior to the beginning of the test. (HP, No. 
30 at p. 2; ITI, No. 6 at p. 3, No. 28 at pp. 2-3; Pub. Mtg. Tr., No. 
17 at pp. 36-37)
    DOE is concerned with minimizing the testing burden on 
manufacturers. Notwithstanding, to be repeatable, a test procedure for 
measuring the energy consumption of consumer electronics must allow 
time for the components to warm up, a process that takes significantly 
longer than 10 seconds. Also, a severely shortened test procedure may 
not accurately measure the energy consumption of BCs with low-frequency 
pulsed operation,\10\ an issue DOE raised in its August 15, 2008, NOPR.
---------------------------------------------------------------------------

    \10\ Some BCs in standby mode operate periodically, consuming 
power in short pulses or bursts to lower overall energy consumption.
---------------------------------------------------------------------------

    Because of the need for a repeatable and accurate test procedure 
that accounts for both warm-up time and pulsed operation, DOE is 
adopting a 1-hour measurement period for both the BC standby mode and 
off mode measurements. This final rule inserts the measurement period 
requirement, and the remaining instructions for BC standby and off mode 
energy consumption measurement, into sections 4(c) and 4(d) of appendix 
Y.
2. Clarifying the BC Standby Mode Test for Integral-Battery Products
    PTI and AHAM commented that care should be taken when specifying 
standby mode test conditions for integral-battery BCs. Testers should 
not attempt to disassemble BCs, but rather remove the entire product 
(with battery) from the charging cradle. (Pub. Mtg. Tr., No. 17 at pp. 
15, 74-75, and 77) AHAM further commented that the definitions of 
standby and off mode should explicitly address integral-battery BCs. 
(AHAM, No. 10 at p. 4)
    DOE acknowledges the commenters' concern about appropriately 
testing BCs where the charging circuitry and the battery are inside one 
enclosure and therefore cannot be separated during typical use. To 
ensure that testers do not disassemble the integral-battery consumer 
product during standby and off mode testing, DOE has inserted a 
clarification within both the standby and off mode test procedure 
amendments specifying that in the case of products with integral 
batteries, `` `disconnecting the battery from the charger' will require 
disconnection of the end-use product'' itself and that standby mode or 
off mode ``power consumption will equal that of the cradle and/or 
adapter alone.'' This final rule inserts this clarification as well as 
a mention of plug blades--the metal prongs that connect a wall-mounted 
adapter to an outlet--as parts of the standby and off mode test 
procedure amendments, into sections 4(c) and 4(d) of appendix Y.
3. Obviating EPS Standby Mode Testing Through End-Use Product Testing
    Microsoft commented that some end-use products powered by EPSs must 
already meet standby mode power consumption standards. Because an EPS-
powered product is tested together with its EPS, standby mode testing 
of the EPS by itself would be ``redundant and possibly in conflict with 
the other requirements * * *'' (Pub. Mtg. Tr., No. 17 at p. 118)
    Although there may be international standards that regulate the 
standby mode power consumption of end-use products powered by EPSs, 
these products (e.g., video-game consoles, printers, networking 
equipment, etc.) are not covered under 10 CFR part 430 and therefore 
not subject to any mandatory testing or standards in the United States. 
Furthermore, even if these products were subject to standards under 10 
CFR part 430, EISA 2007 states that a ``standard for external power 
supplies shall not constitute * * * [a] standard for the separate end-
use product * * *'' Standards for the end-use product should not 
preclude standards (and, by extension, test procedures) for the EPS 
itself. Therefore, this final rule inserts an EPS standby mode test 
procedure into section 4(a)(i) of appendix Z.
4. Modifying the Stability Requirement for Measuring EPS Energy 
Consumption
    In the August 15, 2008, NOPR, DOE proposed amending the EPS test 
procedure to accommodate the testing of multiple-voltage EPSs. Due to 
the large number of stakeholder comments received and the limited time 
for publication of this final rule, DOE has decided to postpone 
consideration of multiple-voltage amendments until it issues a NOPR 
focusing on a BC active mode test procedure in 2009. Nonetheless, DOE 
is including in today's final rule the stability requirement from the 
multiple-voltage EPS test procedure it proposed in August 15, 2008.
    According to the EPA single-voltage EPS test procedure, an EPS can 
be deemed stable if the input ``power level does not drift by more than 
5% from the maximum value observed'' over a 5-minute period. If an EPS 
meets this stability requirement, instantaneous measurements of input 
power, output voltage, and output current can be taken. Otherwise, the 
instantaneous measurements must be averaged over a subsequent 5-minute 
period. (EPA, ``Test Method for Calculating the Energy Efficiency of 
Single-Voltage External AC-DC and AC-AC Power Supplies,'' section 5.d) 
Given that elsewhere in the EPA test procedure, the power measurements 
uncertainty is required to be less than or equal to 2 percent, DOE 
proposed that the multiple-voltage EPS be deemed stable if the input 
power does not drift by more than 1 percent from the maximum value 
observed over a 5-minute period. 73 FR 48054, 48072 (August 15, 2008).
    Stakeholders were generally receptive to this change in the 
stability criterion. Australia agreed with the proposed 1-percent 
stability requirement, but commented that samples should also be taken 
every second. (Australia, No. 20 at p. 3) Wahl Clipper Corporation 
(Wahl) suggested that DOE consider opening up the proposed 1-percent 
stability requirement at lower output powers, where 1 percent of input 
power may be insignificant. (Pub. Mtg. Tr., No. 17 at p. 166)
    In the August 15, 2008, NOPR, DOE stated that it would consider 
making equivalent changes to the existing active and no-load mode test 
procedure for single-voltage EPSs based on departures from the 
stability criterion and other requirements, but declined to include 
these changes in today's final rule because of resistance to modifying 
the previously adopted and internationally accepted active and no-load 
mode EPS test procedure. (EPA, ``Test Method for

[[Page 13325]]

Calculating the Energy Efficiency of Single-Voltage External AC-DC and 
AC-AC Power Supplies'') Nonetheless, because of stakeholder support for 
a more stringent stability criterion and the lack of an internationally 
accepted off mode test procedure, DOE is including the 1-percent 
stability requirement in today's final rule as part of the new off mode 
test procedure for single-voltage EPSs.
    Furthermore, today's rule addresses Wahl's comment by deeming EPS 
as stable at input powers less than 5 watts if the power does not vary 
by more than 50 milliwatts. DOE has tested EPSs with output parameters 
of 1 watt at 5 volts. At such low output powers, the output ripple and 
other noise may indeed surpass the 1-percent stability requirement, as 
Wahl claims. Therefore, today's final rule inserts the modified 
stability criterion, which was originally part of the proposed 
multiple-voltage EPS test procedure, into section 4(a)(ii) of appendix 
Z (single-voltage EPSs).
5. Clarifying the Assessment Point for AC Input Power Into the EPS
    Regarding DOE's proposed test procedure for multiple-voltage EPSs, 
Texas Instruments (TI), PTI, and AHAM commented that DOE should specify 
on which side of the input power meter to measure the input voltage to 
ensure compliance with source voltage, total harmonic distortion, and 
other requirements. The input power meter can have an impact on those 
parameters. (Pub. Mtg. Tr., No. 17 at pp. 138-139 and 140).
    The existing EPA single-voltage EPS test procedure already 
specifies that ``the input to the UUT [unit under test] shall be the 
specified voltage <plus-minus>1% and the specified frequency <plus-
minus>1%'' (EPA, ``Test Method for Calculating the Energy Efficiency of 
Single-Voltage External AC-DC and AC-AC Power Supplies,'' section 4.d). 
Because the unit under test is defined as the EPS itself, the point of 
measurement is between the EPS and the input power meter. This is in 
accordance with longstanding testing practice, which dictates that 
testing conditions should be verified as close to the unit under test 
as possible. Today's final rule therefore does not insert any 
clarifications into appendix Z.
6. Clarifying the Disconnection Point for Standby Mode Testing for 
Systems With More Than Two Major Enclosures
    In the August 15, 2008, NOPR, DOE proposed applying the active mode 
and no-load mode test procedure as its standby mode test procedure. PTI 
and AHAM commented that in systems with more than two major enclosures, 
the disconnection point for no-load mode can be unclear, possibly 
leading to a lack of repeatable test results. For instance, if one 
considers a wall adapter for a cradle-charged integral-battery BC 
(e.g., a cordless telephone) as an EPS, it is unclear whether the 
disconnection point would be located between the wall adapter and 
cradle, or between the cradle and the integral-battery product. (Pub. 
Mtg. Tr., No. 17 at p. 112)
    The August 15, 2008, NOPR instructed that if the multiple-
enclosure, cradle-charger system is tested as a BC, the disconnection 
point during standby mode should be between the end-use product and the 
cradle, reflecting typical user behavior. 73 FR 48054, 48080. However, 
if the system is to be tested as an EPS, the disconnection point during 
standby mode should be between the wall adapter and the cradle. This 
interpretation is based on EISA 2007, which defines a Class A EPS as 
``designed to convert line voltage AC input into lower voltage AC or DC 
output'' and ``contained in a separate physical enclosure from the end-
use product. (42 U.S.C. 6291(36)(C)(i)(I) and (IV)) It is also 
consistent with other, non-portable EPS applications where only the 
wall adapter is subject to EPS testing. Accordingly, it is not 
necessary to insert any language clarifying this issue into appendices 
Y and Z.
7. Specifying and Reporting the Shunt Resistance Value Used During EPS 
Measurement
    In response to DOE's proposed test procedures for BC and EPS 
standby and off mode measurement, TI commented that the shunt 
resistance used by the input power meter for current measurement could 
affect measured power values in some cases. (TI, No. 18 at pp. 5-6) TI 
also commented that the test procedure should require that a record of 
the maximum shunt resistance value be kept (perhaps by the 
manufacturer) so that the measurement can be repeated in the event of 
an audit. (TI, No. 18 at p. 6)
    TI focused its analysis on an EPS without power-factor correction 
(PFC),\11\ but did not demonstrate that shunt resistance will 
significantly affect the average measured standby or off mode power 
consumption of EPSs without PFC. TI also speculated, but did not 
demonstrate, that shunt resistance will significantly affect the power 
consumption of EPSs with PFC.
---------------------------------------------------------------------------

    \11\ Manufacturers use PFC circuits to decrease resistive losses 
in the transmission and distribution wiring by correcting 
distortions in the shape of the EPS input current waveform.
---------------------------------------------------------------------------

    Because of a lack of evidence that shunt resistance will 
significantly affect the power consumption of EPSs with or without PFC, 
today's final rule does not require reporting the shunt resistance 
value used during BC and EPS standby or off mode measurement.
8. Excluding EPSs That Do Not Operate in Standby or No-Load Modes From 
Standby Mode Testing
    AHAM and PTI voiced general agreement with DOE's proposed changes 
to the EISA 2007 standby and off mode definitions and proposed test 
procedures for these two modes (AHAM & PTI, No. 24 at pp. 1-2), while 
the Security Industry Association (SIA), Tyco, Uniden, the Consumer 
Electronics Association (CEA), Brink's, and the National Burglar and 
Fire Alarm Association (NBFAA) commented that DOE should exempt EPSs 
for security and telephony applications from being tested in no-load, 
standby,\12\ and off modes. Such products never operate in these modes 
during actual use, and regulation would result in no energy savings, 
only added costs. (SIA, No. 7 at pp. 1-2, No. 22 at pp. 3-4; Pub. Mtg. 
Tr., No. 17 at pp. 19-21, 23-26, 42-43; Tyco, No. 4 at p. 2, No. 29 at 
pp. 3-4; CEA, No. 26 at p. 2; Brink's, No. 19 at p. 1; NBFAA, No. 32 at 
p. 2) ITI recommended that DOE consider allowing exclusions from the 
test procedure for some products. (Pub. Mtg. Tr., No. 17 at pp. 37-38)
---------------------------------------------------------------------------

    \12\ For EPSs, standby mode is no-load mode, except with all 
manual on-off switches turned on. However, because the no-load mode 
test procedure already requires that the EPS be tested with all 
manual on-off switches turned on, the test procedure for no-load 
mode and standby mode are the same.
---------------------------------------------------------------------------

    Tyco further noted that surveillance equipment typically uses 60 Hz 
waveform from AC-AC EPS to synchronize images. These adapters may need 
to be modified if subject to EISA 2007 no-load mode requirements, 
affecting the utility of the systems. (Tyco, No. 29 at p. 4)
    Tyco also commented that DOE previously found that standby mode 
does not apply to fluorescent lamps, which, like security systems, are 
either on or completely powered off. (Tyco, No. 4 at p. 2, No. 29 at 
pp. 4-6; Pub. Mtg. Tr., No. 17 at p. 25) Because standby mode does not 
apply, Tyco and SIA suggested instead that EPSs for security 
applications be marked ``IVa,'' where ``IV'' indicates the 
international efficiency level, while ``a'' indicates active mode only. 
(Tyco, No. 4 at p. 5; SIA, No. 7 at p. 3)
    In the above comments, manufacturers in the security and telephony 
industries argue that EPSs for security applications be exempted from

[[Page 13326]]

testing under the off mode test procedure proposed in the August 15, 
2008, NOPR. The commenters further argue that EPSs for security 
applications be exempted from testing under the new standby mode test 
procedure--i.e., the existing no-load mode test procedure--so that they 
will not have to meet the EISA 2007 no-load standards effective on July 
1, 2008.
    Regarding exempting EPSs for security applications from testing 
under the off mode test procedure, the off mode definition proposed in 
the August 15, 2008, NOPR applies only to EPSs with manual on-off 
switches. Therefore, EPSs without manual on-off switches cannot be 
tested under the new off mode test procedure. 73 FR 48054, 48063 
(August 15, 2008). According to the comments, EPSs for security 
applications do not have on-off switches, and therefore would not be 
tested under the off mode test procedure.
    Regarding exempting EPSs for security applications from testing 
under the standby mode (i.e., no-load mode) test procedure, it appears 
that manufacturers are also requesting that EPSs for home security and 
other applications that do not operate in standby or no-load modes be 
exempt. Although EISA 2007 gave DOE discretion in developing standby 
and off mode test procedures and definitions, (42 U.S.C. 6295(gg)(1)(B) 
and (2)(A)), the proposed standby mode test procedure is the existing 
no-load test procedure, and EISA 2007 does not allow DOE to modify the 
existing no-load definition and test procedure. More specifically, 
section 301 of EISA 2007 modified section 325 of EPCA to set a no-load 
mode power consumption standard (42 U.S.C. 6295(u)(3)(A)), and further 
modified section 323 to specify that DOE must continue using a test 
procedure based on the EPA's single-voltage EPS test procedure. (42 
U.S.C. 6293(b)(17))
    In addition to mandating an energy conservation standard for Class 
A EPSs, Congress provided exclusions from the standard for specific 
classes of EPSs (e.g., EPSs for medical applications) by placing them 
outside of Class A. (42 U.S.C. 6291(36)(C)(ii)) If DOE were to modify 
the no-load test procedure to exempt EPSs for home security 
applications, DOE would in effect be granting an additional exclusion 
from the Class A standard, contravening EISA 2007. In the case of 
statutory standards, DOE does not have the authority to grant a request 
for a waiver from the test procedure or for an exception from the 
standard; under 10 CFR 1003.20(a), DOE can only grant exceptions from 
rules or regulations promulgated by DOE, not those mandated by 
Congress.
    Therefore, today's final rule does not include any exemptions from 
the standby or off mode test procedures for EPSs that do not operate in 
these modes, such as those for home security or telephony applications. 
Instead, it inserts the definitions and test procedures for EPS standby 
and off modes that were discussed previously into appendix Z.
    To test EPSs that do not operate in standby or no-load modes and 
that in some cases cannot be easily removed from their end-use 
products, manufacturers need to follow the DOE EPS test procedure. ``If 
the power supply is attached directly to the product that it is 
powering, [manufacturers must] cut the cord immediately adjacent to the 
powered product and connect output measurement probes at that point.'' 
(EPA, ``Test Method for Calculating the Energy Efficiency of Single-
Voltage External AC-DC and AC-AC Power Supplies,'' section 5.a; 
incorporated by reference into section 4 of appendix Z)

C. Clarification of Test Procedure Definitions

    In the August 15, 2008, NOPR, DOE proposed amending the EPS test 
procedure in appendix Z by modifying some existing definitions and 
adding new ones to improve clarity and consistency with industry 
standards. 73 FR 48054, 48068.
    Following publication of the August 15, 2008, NOPR, stakeholders 
commented on the definitions DOE proposed. These commenters suggested 
that DOE provide additional clarification in the application of its 
test procedure. In particular, stakeholders submitted comments on the 
proposed (1) clarification of the definition of ``consumer product'' 
and (2) insertions of additional definitions identifying specific BC 
configurations.
1. Clarification of the Definition of ``Consumer Product''
    PG&E and ACEEE commented that DOE should clarify the definition of 
``consumer product'' along the lines presented during the September 
2008 public meeting, where DOE indicated that consumer products are 
products that are to any significant extent distributed in commerce for 
use by individuals. Similarly, DOE indicated at the meeting that the 
only things that are not consumer products are those that are 
distributed only to commercial and industrial customers. (PG&E & ACEEE, 
No. 21 at p. 2)
    Tyco and SIA commented that regardless of common application in 
residential homes, security, surveillance, and life-safety systems 
should not be considered consumer products. (Tyco, No. 29 at p. 2; SIA, 
No. 22 at p. 2) SIA added that residential users of security systems 
are ``simply the beneficiaries of this commercial service.'' (SIA, No. 
22 at p. 2)
    In response to the request for clarification, the term ``consumer 
product'' is defined as any energy-consuming product other than an 
automobile, ``which, to any significant extent, is distributed in 
commerce for personal use or consumption by individuals.'' (42 U.S.C. 
6291(1)) This definition, which determines the scope of the EISA 2007 
Class A EPS standards that came into effect on July 1, 2008, is 
consistent with the guidance DOE presented during the September 12, 
2008, public meeting. DOE also indicated at the meeting that although 
it could not quantify the term ``to any significant extent,'' it was 
clear that any product that was only distributed in the commercial and 
industrial sectors was not a consumer product. (Pub. Mtg. Tr., No. 17 
at pp. 85-90) This DOE clarification of the definition of consumer 
product is different from the interpretation that was received in 
comments from PG&E and ACEEE.
    In response to the comments on the scope of the consumer product 
definition, DOE notes that cellular telephones are consumer products 
and security systems are no different. In both cases, consumers 
purchase the product with a service contract and pay monthly fees for 
the service, without which the product itself does not function. In 
both cases, the consumer also pays the energy cost associated with 
operating the product.
    Therefore, in today's final rule, DOE is not including any 
additional clarification of the term ``consumer product'' or excluding 
any products from the test procedure on the grounds that they may not 
be consumer products.
2. Insertion of Additional Definitions Identifying Specific BC 
Configurations
    In the modifications to the BC test procedure incorporating standby 
and off mode measurement presented in the August 15, 2008, NOPR, DOE 
relied on terms such as ``cradle'' and ``detachable'' to clarify the 
application of the proposed standby and off mode definitions to various 
configurations of BCs. In comments submitted following publication of 
the NOPR, PTI, and AHAM recommended that DOE include definitions for 
integral, detachable, and

[[Page 13327]]

cradle-type BCs. (Pub. Mtg. Tr., No. 17 at p. 15) They further noted 
that these definitions should be consistent with those proposed for 
inclusion in the ``Energy Efficiency Battery Charger System Test 
Procedure'' currently in development by the California Energy 
Commission (CEC). (PTI, No. 17 at p. 15; AHAM & PTI, No. 24 at pp. 2 
and 4-5; AHAM, No. 10 at p. 4)
    Section 2 of appendix Y already contains definitions of detachable 
and integral batteries, and DOE believes the existing definitions 
provide sufficient clarity for these two battery configurations. 
However, to further clarify the application of standby and off mode, 
DOE is including the following definition of ``cradle'' in today's 
final rule:

    Cradle is an electrical interface between an integral battery 
product and the rest of the battery charger designed to hold the 
product between uses.

    This definition is consistent with that included by the CEC in its 
BC test procedure. Today's final rule inserts this definition in 
section 2.f of appendix Y.

D. Switch-Selectable Single-Voltage EPSs

    In the August 15, 2008, NOPR, DOE proposed language clarifying the 
testing required of switch-selectable single-voltage EPSs. These 
devices have a single output but incorporate a switch that enables 
users to vary the voltage at that output. Because these EPSs have a 
single output, they fall within the scope of EISA 2007 Class A 
standards, but the existing EPS test procedure is unclear at which 
setting they should be tested. Therefore, DOE proposed that a switch-
selectable EPS be tested at both its lowest and highest selectable 
output voltage.
    In written comments, Australia agreed with the DOE proposal to test 
switch-selectable EPSs at their highest and lowest output voltages. 
(Australia, No. 20 at p. 3) Because no stakeholders opposed this 
proposal, DOE is including requirements that switch-selectable EPSs 
have their active-mode efficiency, standby mode power consumption, and 
off mode power consumption tested at their highest and lowest voltages 
in today's final rule. Today's final rule will insert these 
requirements into sections 4(a)(i) and 4(a)(ii) of appendix Z and into 
the certification requirements in 10 CFR 430.62(a)(4)(xxiii) and 
(xxiv). The certification requirements are discussed further in section 
III.E.

E. Certification Requirements for EPSs

    Manufacturers of covered and regulated products must file testing 
documentation with DOE and certify that the products they are 
distributing into commerce in the United States comply with Federal 
energy conservation standards. Because EISA 2007 modified EPCA by 
establishing standards for Class A EPSs, DOE proposed in its August 15, 
2008, NOPR to modify the certification requirements to cover the 
submission of data on EPSs. 73 FR 48054, 48072. These certification 
requirements work in concert with the EPS test procedure in appendix Z 
and the sampling plan proposed in the July 25, 2006, NOPR, 71 FR 42178, 
42204, instructing manufacturers how to demonstrate compliance with 
EISA 2007 standards for Class A EPSs.\13\
---------------------------------------------------------------------------

    \13\ Because the sampling requirements proposed in the July 25, 
2006, NOPR have not yet been finalized, manufacturers cannot and 
need not submit certification reports for EPSs at this time.
---------------------------------------------------------------------------

    In the August 15, 2008, NOPR, DOE included requirements that for 
each ``basic model'' of EPS, manufacturers provide the active-mode 
efficiency and no-load-mode power consumption as well as general 
information about that basic model. However, because of the extent of 
customization within the EPS industry and the expected burden 
associated with certifying the compliance of each basic model, DOE 
noted that it was also considering certification requirements based on 
design families. The ENERGY STAR program uses such a structure for 
EPSs. Manufacturers need only submit data on the lowest- and highest-
voltage unit of each design family, which is a collection of basic 
models that share the same output power and fundamental design but may 
have different output voltages. Despite this reduced requirement, 
manufacturers would nonetheless be responsible for the compliance of 
all basic models within the design family.
    Following publication of the August 15, 2008, NOPR, stakeholders 
commented on the option of certifying compliance by design family. 
Stakeholders raised the following issues: (1) The data reporting 
method; (2) clarification of ``certification'' versus ``declaration''; 
(3) exemption from certification requirements of products that had 
qualified under the ENERGY STAR program; (4) the data necessary to 
certify compliance; (5) reporting of additional data absent a complete 
nameplate; and (6) definitions of ``basic model'' and ``design 
family.'' These issues are discussed below.
1. Data Reporting Method
    ITI commented that requiring manufacturers to report efficiency of 
EPSs may be more burdensome than maintaining readily available records 
at their facilities and stated that Congress did not mandate reporting 
requirements as part of EISA 2007. (ITI, No. 6 at p. 2, No. 28 at pp. 
1-2; Pub. Mtg. Tr., No. 17 at pp. 34-35 and 209) However, Ecos 
responded that the DOE reporting requirements are no more burdensome 
than the requirements under the voluntary ENERGY STAR program and 
mandatory State efficiency programs (Pub. Mtg. Tr., No. 17 at p. 211)
    AHAM commented that reporting instills in manufacturers a 
realization of their compliance obligations and that there are 
mechanisms for easing the burdens of compliance, such as centralized 
submissions of data to several agencies through a trade association. 
(Pub. Mtg. Tr., No. 17 at pp. 213-214) AHAM and PTI also expressed 
their preference for the family approach to reporting. (AHAM & PTI, No. 
24 at p. 5)
    While the reporting requirements proposed in the August 15, 2008, 
NOPR are typical of the requirements of other products covered by 10 
CFR part 430, allowing manufacturers to certify results for only the 
lowest- and highest-voltage models within a design family may be the 
least burdensome approach for achieving the objectives of 
certification. Such an approach would also be consistent with the 
approach of other EPS efficiency programs, such as ENERGY STAR.
    Based on these considerations and the comments provided by 
stakeholders, DOE is including in this final rule a requirement that 
manufacturers certify the compliance of design families, supported by 
submissions of active-mode efficiency and no-load power consumption 
data for the highest- and lowest-voltage models within the families. 
Today's final rule inserts these requirements into 10 CFR 
430.62(a)(4)(xxiii).
2. Clarification of ``Certification'' Versus ``Declaration''
    During the September 2008 public meeting, Microsoft recommended 
that DOE use the term ``declaration'' when referring to claims made by 
a manufacturer and ``certification'' when an independent third party 
verifies such claims, as is common industry practice. (Pub. Mtg. Tr., 
No. 17 at pp. 201-202)
    Despite industry custom, the term ``certification'' is used 
unambiguously throughout subpart F of 10 CFR part 430 to refer to 
manufacturer self-certification of their products. For instance, 
paragraph (a)(1) of 10 CFR 430.62 states that ``each manufacturer * * * 
shall certify by means of a compliance

[[Page 13328]]

statement and certification report,'' which is to be ``signed by the 
company official submitting the statement.'' Paragraph (e), ``Third 
party representation,'' of the same section permits, but does not 
require, manufacturers to use a third party to submit compliance 
statements or certification data on the manufacturer's behalf. Because 
the term ``certification'' is used unambiguously throughout 10 CFR part 
430, DOE is not changing ``certification'' to ``declaration'' in 
today's final rule.
3. Exemption From Certification Requirements of Products that 
Previously Qualified Under the ENERGY STAR Program
    ITI recommended that DOE deem ENERGY STAR-qualified EPSs compliant 
with EISA 2007 requirements and not require manufacturers to certify 
their compliance in a separate submission to DOE. (ITI, No. 6 at pp. 4-
5, No. 28 at p. 2)
    Although DOE is sensitive to the reporting burden on manufacturers, 
it requires that the compliance of products subject to energy 
conservation standards under 10 CFR part 430 be certified and reported 
to DOE, regardless of whether the products have qualified under the 
requirements of the ENERGY STAR program. 10 CFR 430.62(a). Because EPSs 
are covered products under 10 CFR 430.2 and subject to standards 
included in EISA 2007 by Congress, (42 U.S.C. 6295(u)(3)(A)), 
manufacturers will have to demonstrate the compliance of their EPSs 
\14\ according to 10 CFR 430.62.
---------------------------------------------------------------------------

    \14\ Manufacturers are not required to certify compliance with 
EISA 2007 standards to DOE until the sampling requirements proposed 
in the July 25, 2006, NOPR are finalized. 71 FR 72178, 72204. 
However, manufacturers are required to be in compliance with the 
standards in the meantime.
---------------------------------------------------------------------------

    Furthermore, the sampling plans of DOE (presented in the July 25, 
2006, NOPR) and ENERGY STAR will most likely differ. This could impact 
the compliance of models when the differences between ENERGY STAR 
guidelines and EISA 2007 standards are small enough (or nonexistent, as 
for the no-load power consumption for AC-AC EPSs) and manufacturing 
variations lead to significant differences in EPS efficiency or no-load 
power from one unit to the next of a single model.
    ENERGY STAR requires manufacturers to test three randomly chosen 
units of the same model and self-certify the compliance of all three 
units for the model to qualify. (EPA, ``ENERGY STAR Program 
Requirements for Single Voltage External AC-DC and AC-AC Power 
Supplies: Eligibility Criteria,'' Version 2.0, sections 4.B and 4.E). 
In contrast in the July 25, 2006, NOPR, DOE proposed that ``a sample of 
sufficient size shall be selected at random and tested to ensure that * 
* * (2) Any represented value of the estimated energy consumption of a 
basic model for which consumers would favor higher values [e.g., active 
mode efficiency] shall be no greater than the lower of: (i) The mean of 
the sample, or (ii) The lower 97.5 percent confidence limit of the true 
mean divided by 0.95.'' 71 FR 42178, 42204.
    If adopted by DOE in a final rule, this different sampling 
requirement could result in manufacturers certifying lower active mode 
efficiency and higher no-load power consumption results--for the same 
model--to DOE than to ENERGY STAR. Therefore, today's final rule does 
not exempt ENERGY STAR-qualified EPSs from DOE certification 
requirements.
4. Data Necessary to Certify Compliance
    Ecos commented that the August 15, 2008, NOPR was unclear whether 
manufacturers should, for each unit tested, submit to DOE the 
efficiency values measured at each of the four active mode loading 
conditions (25 percent, 50 percent, 75 percent, and 100 percent of 
nameplate output current) or only submit their average. (Pub. Mtg. Tr., 
No. 17 at p. 203) PG&E and ACEEE commented that manufacturers should 
submit to DOE the efficiency values measured at each loading condition, 
and not just the average, as the additional detail may aid DOE in 
developing future standards. (PG&E & ACEEE, No. 21 at p. 4)
    However, ITI commented that data submission and certification are 
burdensome and requested that DOE not require data submission out of 
convenience and consider ways of minimizing the manufacturer reporting 
burden. (ITI, No. 28 at pp. 1-2) HP suggested that DOE allow 
manufacturers to self-test and certify without requiring extensive 
reporting of test results. (HP, No. 30 at p. 2)
    There does not appear to be a significant regulatory or analytical 
benefit to systematically collecting intermediate efficiency values at 
each of the loading conditions in addition to their average. Therefore, 
today's final rule requires that only average active-mode efficiency be 
reported.\15\ Nonetheless, manufacturers ``shall establish, maintain, 
and retain the records of the underlying test data'' (e.g., the 
efficiency values measured at each active-mode loading condition) and 
make them available to DOE upon request. 10 CFR 430.62(d).
---------------------------------------------------------------------------

    \15\ Section 5.e of the EPA single-voltage EPS test procedure 
requires that ``Average efficiency shall also be calculated and 
reported as the arithmetic mean of the efficiency values calculated 
at Test Conditions 1, 2, 3, and 4 in Table 1,'' where the ``Test 
Conditions'' correspond to 100 percent, 75 percent, 50 percent, and 
25 percent of nameplate output current. (EPA, Test Method for 
Calculating the Energy Efficiency of Single-Voltage External AC-DC 
and AC-AC Power Supplies,'' p. 9).
---------------------------------------------------------------------------

    Manufacturers shall report the average active-mode efficiency as a 
percentage and the no-load mode power consumption in watts. Today's 
final rule inserts this requirement into 10 CFR 430.62(c)(4)(xxiii) for 
the highest- and lowest-voltage models in a design family (discussed 
further in section III.E.6) and into 430.62(c)(4)(xxiv) for the highest 
and lowest selectable output voltage for each switch-selectable EPS 
model. Separate active-mode efficiency and no-load mode power 
consumption metrics will be reported for each of the units tested \16\ 
and, in the case of the switch-selectable models, for each of the 
output voltage settings.
---------------------------------------------------------------------------

    \16\ Sampling requirements specifying the selection of units to 
be tested were proposed in the July 25, 2006, NOPR, but have not yet 
been finalized.
---------------------------------------------------------------------------

5. Reporting of Data Absent a Complete Nameplate
    During the September 2008 public meeting, DOE noted that some EPSs 
(e.g., high-power EPSs with output power greater than 250 watts) have 
nameplates that do not list all output parameters necessary to 
calculate the loading conditions specified in the test procedure in 
appendix Z.
    Microsoft commented that dedicated-use EPSs, which are intended for 
operation only with a particular end-use product load, may be another 
category of EPSs without output power, current, or voltage information 
on the nameplate. For these products, the output power may be listed on 
the end-use product. (Pub. Mtg. Tr., No. 17 at p. 161) As an 
alternative, Ecos, PG&E, and ACEEE commented that DOE could require 
manufacturers to provide all required information on the product label. 
(Pub. Mtg. Tr., No. 17 at p. 162; PG&E & ACEEE, No. 21 at p. 3), while 
AHAM suggested direct reporting of the ratings to DOE as a way to forgo 
an additional labeling requirement. (Pub. Mtg. Tr., No. 17 at pp. 162-
163)
    In today's final rule, DOE is adopting the solution proposed by 
AHAM and amending the certification requirements to require reporting 
of the output power for all EPSs and of the output current for EPSs 
that omit it from the nameplate.
    Because the EISA 2007 standard levels depend on output power, (42 
U.S.C. 6295(u)(3)(A)), DOE must require

[[Page 13329]]

manufacturers to report the active mode efficiency, no-load power 
consumption (see section III.E.4), and output power for all EPSs to 
verify compliance with standards. This requirement is consistent with 
the existing paragraphs under 430.62(a)(4), which require manufacturers 
to report the capacity of covered products in cases where the standard 
levels depend on capacity.
    However, the EISA 2007 standard levels do not depend on the output 
current, which is only necessary for calculating the active mode 
loading conditions \17\ required by the test procedure. In most cases 
the output current can therefore be read off the nameplate of the EPS 
being tested; however, DOE does not require manufacturers to list the 
output current on the EPS nameplate and cannot rely on its presence. 
Therefore, DOE is requiring manufacturers to report output current in 
cases where it is absent from the nameplate.
---------------------------------------------------------------------------

    \17\ Section 5.b of the EPA single-voltage EPS test procedure 
requires that active mode efficiency be measured at 100 percent, 75 
percent, 50 percent, and 25 percent of nameplate output current. 
(EPA, ``Test Method for Calculating the Energy Efficiency of Single-
Voltage External AC-DC and AC-AC Power Supplies,'' pp. 6-7).
---------------------------------------------------------------------------

    Today's final rule also amends the definitions of the nameplate 
power and current (section 2 of appendix Z) to refer to this 
manufacturer-supplied output information, which means that the test 
procedure can still be used if these parameters are absent from the 
nameplate.
    Although manufacturers would submit this output parameter 
information directly to DOE, external parties wishing to verify 
manufacturer tests could obtain it by visiting the Resource Room of the 
Building Technologies Program \18\ or requesting it directly from 
manufacturers. These modifications will be inserted into sections 
(a)(4)(xxiii) and (xxiv) of 10 CFR 430.62 and sections 2.l and 2.m of 
appendix Z.
---------------------------------------------------------------------------

    \18\ The U.S. Department of Energy, Resource Room of the 
Building Technologies Program, is located at 950 L'Enfant Plaza, 
SW., Suite 600, Washington, DC, and is open between 9 a.m. and 4 
p.m., Monday through Friday, except Federal holidays. Please call 
Ms. Brenda Edwards at (202) 586-2945 to arrange a visit.
---------------------------------------------------------------------------

6. Definitions of ``Basic Model'' and ``Design Family''
    In the August 15, 2008, NOPR, DOE noted that it was considering 
defining EPS design families as groups of basic models that share 
output power and ``fundamental electrical circuit design,'' but that 
vary by voltage. 73 FR 48054, 48074. (See sections II.D and III.E) 
Ecos, PG&E, and ACEEE commented that DOE should also specify design 
families on the basis of output cord resistance, not cord length, as 
length is not the only parameter that determines cord resistance and 
the resultant losses. (Pub. Mtg. Tr., No. 17 at p. 200; PG&E & ACEEE, 
No. 21 at p. 4).
    Lacking additional stakeholder comments, today's final rule 
contains a definition of ``external power supply design family'' that 
is consistent with the discussion in the August 15, 2008, NOPR, 73 FR 
48054, 48074, and which incorporates the above guidance on cord 
resistance:

    External power supply design family means a set of external 
power supply basic models, produced by the same manufacturer, which 
share the same circuit layout, output power, and output cord 
resistance, but differ in output voltage.

    Today's final rule will insert the above definition into section 2, 
``Definitions,'' of 10 CFR part 430. Furthermore, today's final rule 
also requires that the compliance statement covering each design family 
be supported with test results for the highest- and lowest-voltage 
models within the design family. These requirements will be inserted 
into sections (a)(4)(xxiii) and (xxiv) of 10 CFR 430.62. Figure III.1 
and Figure III.2 present suggested formats for the compliance statement 
and certification report that manufacturers can use to certify the 
compliance of EPS design families, based on the generic format found in 
appendix A to subpart F of part 430.

BILLING CODE 6450-01-C
    Manufacturers wishing to certify the compliance of individual basic 
models should treat them as a design family With one model.

IV. Effect of Test Procedure Revisions on Compliance with Standards

    In amending a test procedure, section 323(e) of EPCA directs DOE to 
determine to what extent, if any, the test procedure would alter the 
measured energy efficiency of the covered product. If the amended test 
procedure alters the measured efficiency, the Secretary must amend the 
applicable energy conservation standard to the extent the amended test 
procedure changes the energy efficiency of products that minimally 
comply with the existing standard. (42 U.S.C. 6293(e)) On July 1, 2008, 
the energy conservation standards contained in section 301(c) of EISA 
2007 regarding the active mode efficiency and no-load mode power 
consumption of Class A EPSs became effective. However, the test 
procedure amendments included in this final rule do not affect 
compliance with these standards because they do not substantively 
change the measurement of active mode efficiency and no-load mode power 
consumption.
    Of the five amendments discussed in section III, only those 
pertaining to (1) standby mode test procedures; (2) test

[[Page 13332]]

procedure definitions; and (3) switch-selectable EPS testing could 
potentially affect compliance with standards. Although this final rule 
amends the current active and no-load mode test procedure so that it 
pertains to the ``measurement of standby mode (also no-load mode) 
energy consumption and active mode efficiency,'' there are no 
substantive changes that would impact testing in active or no-load 
mode. Similarly, although the rule amends and adds to the test 
procedure definitions, the amendments codify generally accepted 
industry definitions without impacting the active or no-load mode 
measurement results.
    Finally, although today's final rule amends the EPS test procedure 
to specify how switch-selectable EPSs should be tested, these 
amendments do not affect standards compliance either. Whereas under the 
existing test procedure manufacturers would test switch-selectable EPSs 
at each output voltage setting, under the amended test procedure, as 
under the ENERGY STAR program, manufacturers need only test these EPSs 
at the highest- and lowest-voltage settings. Nonetheless, a switch-
selectable EPS that was in compliance under the existing test procedure 
will be in compliance under the amended test procedure because the 
efficiencies measured at all the output voltage settings of a switch-
selectable EPS will lie between those measured at the highest- and 
lowest-voltage settings. In other words, a switch-selectable EPS that 
was previously compliant when tested at each of its output voltage 
settings will be deemed compliant at either its highest- or lowest-
voltage setting. Therefore, today's amendment does not impact 
compliance with EISA 2007 EPS standards.
    Because none of the amendments contained in today's rule change the 
measurement of active mode efficiency and no-load mode power 
consumption, the rule has no impact on compliance with the EISA 2007 
EPS standards. There are no existing standards for BCs. There were no 
stakeholder comments on the effects of test procedure amendments on 
compliance with standards.

V. Procedural Requirements

A. Executive Order 12866

    Today's regulatory action is not a ``significant regulatory 
action'' under section 3(f) of Executive Order 12866, ``Regulatory 
Planning and Review,'' 58 FR 51735 (October 4, 1993). Accordingly, this 
action was not subject to review under that Executive Order by the 
Office of Information and Regulatory Affairs (OIRA) of the Office of 
Management and Budget (OMB).

B. Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires 
preparation of an initial regulatory flexibility analysis for any rule 
that by law must be proposed for public comment, unless the Department 
certifies that the rule, if promulgated, will not have a significant 
economic impact on a substantial number of small entities. As required 
by Executive Order 13272, ``Proper Consideration of Small Entities in 
Agency Rulemaking,'' 67 FR 53461 (August 16, 2002), DOE published 
procedures and policies on February 19, 2003, to ensure that the 
potential impacts of its rules on small entities are properly 
considered during the DOE rulemaking process. 68 FR 7990. DOE has made 
its procedures and policies available on the Office of the General 
Counsel's Web site, http://www.gc.doe.gov.
    DOE reviewed today's final rule under the provisions of the 
Regulatory Flexibility Act and the policies and procedures published on 
February 19, 2003. DOE tentatively certified in the August 15, 2008, 
NOPR that the proposed rule would not have a significant impact on a 
substantial number of small entities. 73 FR 48054, 48077. DOE received 
one comment from Power Technology specifically regarding small business 
impacts. (Power Technology, No. 5 at p. 1). While it seems that Power 
Technology does not manufacture EPSs for consumer products, and is 
therefore not directly affected by this rulemaking, DOE would like to 
address the possible concerns of affected parties. While the EPS 
standards that became effective on July 1, 2008 were Congressionally 
mandated, today's rule mitigates their impact by requiring 
certification according to the design family approach. Because of the 
substantially lower burden resulting from this approach, DOE reaffirms 
that this rule will have no significant economic impact on a 
substantial number of small entities.

C. Paperwork Reduction Act

    This rulemaking imposes no new information or recordkeeping 
requirements. See August 15, 2008, NOPR, 73 FR 48054, 48078. 
Accordingly, OMB clearance is not required under the Paperwork 
Reduction Act. (44 U.S.C. 3501 et seq.)

D. National Environmental Policy Act

    This rule is covered under the Categorical Exclusion found in DOE's 
National Environmental Policy Act regulations. This rule amends an 
existing rule without changing its environmental effect, and, 
therefore, is covered by the Categorical Exclusion A5 found in appendix 
A to subpart D, 10 CFR part 1021. Accordingly, neither an environmental 
assessment nor an environmental impact statement is required.

E. Executive Order 13132

    Executive Order 13132, ``Federalism,'' 64 FR 43255 (August 10, 
1999), imposes certain requirements on 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 final rule 
would not have a substantial direct effect on the States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government. Executive Order 13132 requires no further action.

F. Executive Order 12988

    Regarding the review of existing regulations and the promulgation 
of new regulations, section 3(a) of Executive Order 12988, ``Civil 
Justice Reform,'' 61 FR 4729 (February 7, 1996), 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; and (3) provide a clear legal standard for 
affected conduct rather than a general standard and promote 
simplification and burden reduction. Regarding the review required by 
section 3(a), section 3(b) of Executive Order 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 Executive Order 12988 requires Executive agencies to 
review regulations in light of applicable standards in sections 3(a) 
and 3(b) to determine whether they are met or it is unreasonable to 
meet one or more of

[[Page 13333]]

them. DOE has completed the required review and determined that, to the 
extent permitted by law, this rule meets the relevant standards of 
Executive Order 12988.

G. Unfunded Mandates Reform Act of 1995

    The Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4) (UMRA) 
generally requires Federal agencies to examine closely the impacts of 
regulatory actions on State, local, and Tribal governments. Subsection 
101(5) of title I of that law defines a Federal intergovernmental 
mandate to include any regulation that would impose upon State, local, 
or Tribal governments an enforceable duty, except a condition of 
Federal assistance or a duty arising from participating in a voluntary 
federal program. Title II of UMRA requires each Federal agency to 
assess the effects of Federal regulatory actions on State, local, and 
Tribal governments and the private sector. For proposed regulatory 
actions likely to result in a rule that may cause expenditures by 
State, local, and Tribal governments, in the aggregate, or by the 
private sector, of $100 million or more (adjusted annually for 
inflation), section 202 of UMRA requires a Federal agency to publish 
estimates of the resulting costs, benefits, and other effects on the 
national economy. Section 204 of UMRA also requires a Federal agency to 
develop an effective process to permit timely input by elected officers 
of State, local, and Tribal governments on a proposed ``significant 
intergovernmental mandate.'' On March 18, 1997, DOE published a 
statement of policy on its process for intergovernmental consultation 
under UMRA (62 FR 12820) (also available at http://www.gc.doe.gov). 
Today's final rule would modify the current test procedures for BCs and 
EPSs. Today's rule contains neither an intergovernmental mandate, nor a 
mandate that may result in the expenditure by State, local, and Tribal 
governments, or by the private sector, of $100 million or more in any 
year. Accordingly, no assessment or analysis is required under the 
Unfunded Mandates Reform Act of 1995.

H. 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. 
Today's rule would not have any impact on the autonomy or integrity of 
the family as an institution. Accordingly, DOE has concluded that it is 
unnecessary to prepare a Family Policymaking Assessment.

I. Executive Order 12630

    Pursuant to Executive Order 12630, ``Governmental Actions and 
Interference with Constitutionally Protected Property Rights,'' 53 FR 
8859 (March 15, 1988), DOE has determined that this rule would not 
result in any takings that might require compensation under the Fifth 
Amendment to the United States Constitution.

J. Treasury and General Government Appropriations Act, 2001

    The Treasury and General Government Appropriations Act, 2001 (44 
U.S.C. 3516 note) provides for agencies to review most disseminations 
of information to the public under guidelines established by each 
agency pursuant to general guidelines issued by OMB. OMB's guidelines 
were published at 67 FR 8452 (February 22, 2002), and DOE's guidelines 
were published at 67 FR 62446 (October 7, 2002). DOE has reviewed 
today's notice under the OMB and DOE guidelines and has concluded that 
it is consistent with applicable policies in those guidelines.

K. Executive Order 13211

    Executive Order 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 OMB 
a Statement of Energy Effects for any proposed significant energy 
action. A ``significant energy action'' is defined as any action by an 
agency that promulgated 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 proposed significant energy action, 
the agency must give a detailed statement of any adverse effects on 
energy supply, distribution, or use should the proposal be implemented, 
and of reasonable alternatives to the action and their expected 
benefits on energy supply, distribution, and use. Today's regulatory 
action is not a significant regulatory action under Executive Order 
12866 or any successor order; would not have a significant adverse 
effect on the supply, distribution, or use of energy; and has not been 
designated by the Administrator of OIRA as a significant energy action. 
Therefore, it is not a significant energy action. Accordingly, DOE has 
not prepared a Statement of Energy Effects.

L. Section 32 of the Federal Energy Administration Act of 1974

    Under section 301 of the Department of Energy Organization Act 
(Pub. L. 95-91), DOE must comply with all laws applicable to the former 
Federal Energy Administration, including section 32 of the Federal 
Energy Administration Act of 1974 (Pub. L. 93-275), as amended by the 
Federal Energy Administration Authorization Act of 1977 (Pub. L. 95-
70). (15 U.S.C. 788) Section 32 provides that where a proposed rule 
authorizes or requires use of commercial standards, the notice of 
proposed rulemaking must inform the public of the use and background of 
such standards. Section 32(c) also requires DOE to consult with the 
Department of Justice and the Federal Trade Commission (FTC) concerning 
the impact of commercial or industry standards on competition.
    Certain of the amendments and revisions in this final rule 
incorporate testing methods contained in the following commercial 
standards: (1) CEC 2007 Appliance Efficiency Regulations, section 
1604(u)(1), which directly cites ``Test Method for Calculating the 
Energy Efficiency of Single-Voltage External Ac-Dc and Ac-Ac Power 
Supplies''; (2) IEEE Standard 1515-2000, ``IEEE Recommended Practice 
for Electronic Power Subsystems: Parameter Definitions, Test 
Conditions, and Test Methods''; and (3) IEC Standard 62301 ``Household 
electrical appliances--Measurement of standby power.'' As stated in the 
August 15, 2008, NOPR, DOE has evaluated these standards and is unable 
to conclude whether they fully comply with the requirements of section 
32(b) of the Federal Energy Administration Act, (i.e., that they were 
developed in a manner that fully provides for public participation, 
comment, and review). 73 FR 48054, 48079. DOE has consulted with the 
Attorney General and the Chairman of the FTC concerning the impact on 
competition of requiring manufacturers to use the test methods 
contained in these standards, and neither recommended against 
incorporation of these standards.

M. Congressional Notification

    As required by 5 U.S.C. 801, DOE will report to Congress on the 
promulgation of today's rule before its effective date. The report will 
state that it has been determined that the rule is not a ``major rule'' 
as defined by 5 U.S.C. 801(2).

Appendix Y to Subpart B of Part 430--Uniform Test Method for Measuring 
the Energy Consumption of Battery Chargers

* * * * *
    2. Definitions:
* * * * *
    f. Cradle is an electrical interface between an integral battery 
product and the rest of the battery charger designed to hold the 
product between uses.
* * * * *
    h. Manual on-off switch is a switch activated by the user to 
control power reaching the device. This term does not apply to any 
mechanical, optical, or electronic switches that automatically 
disconnect mains power from the device when a battery is removed 
from a cradle or charging base or, for products with non-detachable 
batteries, that control power to the product itself.
* * * * *
    k. Off mode is the condition, applicable only to units with 
manual on-off switches, in which the battery charger is (1) 
connected to the main electricity supply; (2) is not connected to 
the battery; and (3) all manual on-off switches are turned off.
    l. Standby mode (also no-battery mode) means the condition in 
which (1) the battery charger is connected to the main electricity 
supply; (2) the battery is not connected to the charger; and (3) for 
battery chargers with manual on-off switches, all such switches are 
turned on.
* * * * *
    4. Test Measurement:
* * * * *
    (c)(1) Standby Mode Energy Consumption Measurement. Conduct a 
measurement of standby power consumption while the battery charger 
is connected to the power source. Disconnect the battery from the 
charger and record the power (i.e., watts) consumed as the time 
series integral of the power consumed over a 1-hour test period, 
divided by the period of measurement. If the battery charger has 
manual on-off switches, all must be turned on for the duration of 
the standby mode test.
    (2) Standby mode may also apply to products with integral 
batteries. If the product uses a cradle and/or adapter for power 
conversion and charging, then ``disconnecting the battery from the 
charger'' will require disconnection of the end-use product, which 
contains the batteries. The other enclosures of the battery charging 
system will remain connected to the main electricity supply, and 
standby mode power consumption will equal that of the cradle and/or 
adapter alone.
    (3) If the product also contains integrated power conversion and 
charging circuitry and is powered through a detachable AC power 
cord, then only the cord will remain connected to mains, and standby 
mode power consumption will equal that of the AC power cord (i.e., 
zero watts).
    (4) Finally, if the product contains integrated power conversion 
and charging circuitry but is powered through a non-detachable AC 
power cord or plug blades, then no part of the system will remain 
connected to mains, and standby mode measurement is not applicable.
    (d)(1) Off Mode Energy Consumption Measurement. If the battery 
charger has manual on-off switches, record a measurement of off mode 
energy consumption while the battery charger is connected to the 
power source. Remove the battery from the charger and record the 
power (i.e., watts) consumed as the time series integral of the 
power consumed over a 1-hour test period, divided by the period of 
measurement, with all manual on-off switches turned off. If the 
battery charger does not have manual on-off switches, record that 
the off mode measurement is not applicable to this product.
    (2) Off mode may also apply to products with integral batteries. 
If the product uses a cradle and/or adapter for power conversion and 
charging, then ``disconnecting the battery from the charger'' will 
require disconnection of the end-use product, which contains the 
batteries. The other enclosures of the battery charging system will 
remain connected to the main electricity supply, and off mode power 
consumption will equal that of the cradle and/or adapter alone.
    (3) If the product also contains integrated power conversion and 
charging circuitry and is powered through a detachable AC power 
cord, then only the cord will remain connected to mains, and off 
mode power consumption will equal that of the AC power cord (i.e., 
zero watts).
    (4) Finally, if the product contains integrated power conversion 
and charging circuitry but is powered through a non-detachable AC 
power cord or plug blades, then no part of the system will remain 
connected to mains, and off mode measurement is not applicable.

Appendix Z to Subpart B of Part 430--Uniform Test Method for Measuring 
the Energy Consumption of External Power Supplies

    1. Scope: This appendix covers the test requirements used to 
measure energy consumption of external power supplies.
    2. Definitions: The following definitions are for the purposes 
of understanding terminology associated with the test method for 
measuring external power supply energy consumption. For clarity on 
any other terminology used in the test method, please refer to IEC 
Standard 60050 or IEEE Standard 100. (Reference for guidance only, 
see Sec.  430.4.)
    a. Active mode means the mode of operation when the external 
power supply is connected to the main electricity supply and the 
output is (or ``all outputs are'' for a multiple-voltage external 
power supply) connected to a load (or ``loads'' for a multiple-
voltage external power supply).
    b. Active mode efficiency is the ratio, expressed as a 
percentage, of the total real output power produced by a power 
supply to the real input power required to produce it. (Reference 
for guidance only, see IEEE Standard 1515-2000, 4.3.1.1, Sec.  
430.4.)
    c. Active power (also real power) (P) means the root-mean-square 
(RMS) value of the instantaneous power taken over one period. 
(Reference for guidance only, see IEEE Standard 1515-2000, Sec.  
430.4.)
    d. Ambient temperature means the temperature of the ambient air 
immediately surrounding the unit under test.
    e. Apparent power (S) is the product of RMS voltage and RMS 
current (VA).
    f. Instantaneous power means the product of the instantaneous 
voltage and instantaneous current at a port (the terminal pair of a 
load).
    g. Manual on-off switch is a switch activated by the user to 
control power reaching the device. This term does not apply to any 
mechanical, optical, or electronic switches that automatically 
disconnect mains power from the device when a load is disconnected 
from the device, or that control power to the load itself.
    h. Minimum output current means the minimum current that must be 
drawn from an output bus for an external power supply to operate 
within its specifications.
    i. Multiple-voltage external power supply means an external 
power supply that is designed to convert line voltage AC input into 
more than one simultaneous lower-voltage output.
    j. Nameplate input frequency means the AC input frequency of the 
power supply as specified on the manufacturer's label on the power 
supply housing.
    k. Nameplate input voltage means the AC input voltage of the 
power supply as specified on the manufacturer's label on the power 
supply housing.
    l. Nameplate output current means the current output of the 
power supply as specified on the manufacturer's label on the power 
supply housing (either DC or AC) or, if absent from the housing, as 
provided by the manufacturer.
    m. Nameplate output power means the power output of the power 
supply as specified on the manufacturer's label on the power supply 
housing or, if absent from the housing, as specified in 
documentation provided by the manufacturer.
    n. Nameplate output voltage means the voltage output of the 
power supply as specified on the manufacturer's label on the power 
supply housing (either DC or AC).
    o. No-load mode means the mode of operation when an external 
power supply is connected to the main electricity supply and the 
output is (or ``all outputs are'' for a multiple-voltage external 
power supply) not connected to a load (or ``loads'' for a multiple-
voltage external power supply).
    p. Off mode is the condition, applicable only to units with 
manual on-off switches, in which the external power supply is (1) 
connected to the main electricity supply; (2) the output is not 
connected to any load; and (3) all manual on-off switches are turned 
off.
    q. Output bus means any of the outputs of the power supply to 
which loads can be connected and from which power can be drawn, as 
opposed to signal connections used for communication.
    r. Single-voltage external AC-AC power supply means an external 
power supply that is designed to convert line voltage AC input into 
lower voltage AC output and is able to convert to only one AC output 
voltage at a time.
    s. Single-voltage external AC-DC power supply means an external 
power supply that is designed to convert line voltage AC input into 
lower-voltage DC output and is able to convert to only one DC output 
voltage at a time.
    t. Standby mode means the condition in which the external power 
supply is in no-load mode and, for external power supplies with 
manual on-off switches, all such switches are turned on.
    u. Switch-selectable single voltage external power supply means 
a single-voltage AC-AC or AC-DC power supply that allows users to 
choose from more than one output voltage.
    v. Total harmonic distortion, expressed as a percentage, is the 
RMS value of an AC signal after the fundamental component is removed 
and interharmonic components are ignored, divided by the RMS value 
of the fundamental component. THD of current is defined as:
[GRAPHIC] [TIFF OMITTED] TR27MR09.409

where In is the RMS value of the nth harmonic of the current signal.

    w. True power factor (PF) is the ratio of the active power (P) 
consumed in watts to the apparent power (S), drawn in volt-amperes.
[GRAPHIC] [TIFF OMITTED] TR27MR09.410

This definition of power factor includes the effect of both 
distortion and displacement.

    x. Unit under test is the external power supply being tested.

    4. Test Measurement:
    (a) Single-Voltage External Power Supply
    (i) Standby Mode and Active Mode Measurement--The measurement of 
standby mode (also no-load mode) energy consumption and active mode 
efficiency shall conform to the requirements specified in section 5, 
``Measurement Approach'' of the CEC's ``Test Method for Calculating 
the Energy Efficiency of Single-Voltage External Ac-Dc and Ac-Ac 
Power Supplies,'' August 11, 2004, (incorporated by reference, see 
Sec.  430.3). Switch-selectable single-voltage external power 
supplies shall be tested twice--once at the highest nameplate output 
voltage and once at the lowest.
    (ii) Off-Mode Measurement--If the external power supply unit 
under test incorporates manual on-off switches, the unit under test 
shall be placed in off mode, and its power consumption in off mode 
measured and recorded. The measurement of the off mode energy 
consumption shall conform to the requirements specified in section 
5, ``Measurement Approach,'' of the CEC's ``Test Method for 
Calculating the Energy Efficiency of Single-Voltage External Ac-Dc 
and Ac-Ac Power Supplies,'' August 11, 2004 (incorporated by 
reference, see Sec.  430.3), with two exceptions. In section 5.a, 
``Preparing UUT [Unit Under Test] for Test,'' all manual on-off 
switches shall be placed in the ``off'' position for the 
measurement. In section 5.d, ``Testing Sequence,'' the technician 
shall consider the UUT stable if, over 5 minutes with samples taken 
at least once every second, the AC input power does not drift from 
the maximum value observed by more than 1 percent or 50 milliwatts, 
whichever is greater. The only loading condition that will be 
measured for off mode is ``Load Condition 5'' in Table 1 of the 
CEC's test procedure. Switch-selectable single-voltage external 
power supplies shall have their off mode power consumption measured 
twice-- once at the highest nameplate output voltage and once at the 
lowest.
    (b) Multiple-Voltage External Power Supply. [Reserved]
