Energy Conservation Program: Test Procedures for Fluorescent Lamp 
Ballasts

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

ACTION: Final rule.

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

SUMMARY: The U.S. Department of Energy (DOE) issues a final rule 
amending the existing test procedures for fluorescent lamp ballasts at 
Appendix Q and establishing a new test procedure at Appendix Q1. The 
amendments to appendix Q update a reference to an industry test 
procedure. The new test procedure at Appendix Q1 changes the efficiency 
metric to ballast luminous efficiency (BLE), which is measured directly 
using electrical measurements instead of the photometric measurements 
employed in the test procedure at Appendix Q. The calculation of BLE 
includes a correction factor to account for the reduced lighting 
efficacy of low frequency lamp operation. The test procedure specifies 
use of a fluorescent lamp load during testing, allowing ballasts to 
operate closer to their optimal design points and providing a better 
descriptor of real ballast performance compared to resistor loads. If 
DOE determines that amendments to the fluorescent lamp ballast energy 
conservation standards are required, they will be issued or published 
by June 30, 2011, and use of the test procedures at Appendix Q1 will be 
required on the compliance date of the amendments. Until that time, 
manufacturers must use the procedures at Appendix Q to certify 
compliance.

DATES: The effective date of the final rule is June 3, 2011. After 
October 31, 2011, manufacturers may not make any representation 
regarding fluorescent lamp ballast efficiency unless such ballast has 
been tested in accordance with the final rule provisions in Appendix Q.
    The incorporation by reference of certain standards in this 
rulemaking is approved by the Director of the Office of the Federal 
Register as of June 3, 2011.

I. Authority and Background

    Title III of the Energy Policy and Conservation Act (42 U.S.C. 
6291, et seq.; ``EPCA'' or, ``the Act'') sets forth a variety of 
provisions designed to improve energy efficiency. (All references to 
EPCA refer to the statute as amended through the Energy Independence 
and Security Act of 2007 (EISA 2007), Pub. L. 110-140 (Dec. 19, 2007)). 
Part B of title III (42 U.S.C. 6291-6309), which was re-designated as 
Part A on codification in the U.S. Code for editorial reasons, 
establishes the ``Energy Conservation Program for Consumer Products 
Other Than Automobiles.'' These include fluorescent lamp ballasts, the 
subject of today's notice. (42 U.S.C. 6291(1), (2) and 6292(a)(13))
    Under EPCA, this program consists essentially of three parts: (1) 
Testing, (2) labeling, (3) Federal energy conservation standards, and 
(4) certification and enforcement procedures. The testing requirements 
consist of test procedures that manufacturers of covered products must 
use (1) as the basis for certifying to DOE that their products comply 
with the applicable energy conservation standards adopted under EPCA, 
and (2) for making representations about the efficiency of those 
products. Similarly, DOE must use these test requirements to determine 
whether the products comply with any relevant standards promulgated 
under EPCA.
    The Energy Independence and Security Act of 2007 also amended EPCA 
to require DOE to review test procedures for all covered products at 
least once every seven years. DOE must either amend the test procedures 
or publish notice in the Federal Register of any determination not to 
amend a test procedure. (42 U.S.C. 6293(b)(1)(A)) To fulfill this 
periodic review requirement, DOE invited comment on all aspects of the 
existing test procedures for fluorescent lamp ballasts that appear at 
Title 10 of the CFR part 430, Subpart B, Appendix Q (``Uniform Test 
Method for Measuring the Energy Consumption of Fluorescent Lamp 
Ballasts'').
    In a separate rulemaking proceeding, DOE is considering amending 
energy conservation standards for fluorescent lamp ballasts (docket 
number EERE-2007-BT-STD- 0016; hereinafter referred to as the 
``standards rulemaking''). DOE initiated that rulemaking by publishing 
a Federal Register (FR) notice announcing a public meeting and 
availability of the framework document (``Energy Efficiency Program for 
Consumer Products: Public Meeting and Availability of the Framework 
Document for Fluorescent Lamp Ballasts'') on January 22, 2008. 73 FR 
3653. On February 6, 2008, DOE held a public meeting in Washington, DC 
to discuss the framework document for the standards rulemaking 
(hereinafter referred to as the ``2008 public meeting''). At that 
meeting, attendees also discussed potential revisions to the test 
procedure for active mode energy consumption relevant to this test 
procedure rulemaking. On March 24, 2010, DOE published a notice of 
public meeting and availability of the preliminary technical support 
document (TSD) for the standards rulemaking. 75 FR 14319. On April 26, 
2010, DOE held a public meeting to discuss the standards preliminary 
analysis and the proposed test procedure discussed below. On April 11, 
2011, DOE published a notice of public rulemaking (NOPR) for the 
fluorescent lamp ballast standards rulemaking. 76 FR 20090.
    For the test procedure, DOE published a NOPR on March 24, 2010. 75 
FR 14288. As indicated above, on April 26, 2010, DOE held a public 
meeting to discuss the test procedure proposals in the NOPR and the 
preliminary TSD for the standards rulemaking (hereafter ``NOPR public 
meeting''). DOE modified the test procedure based on the comments it 
received on the NOPR. On November 24, 2010, DOE published a test 
procedure supplemental notice of proposed rulemaking (SNOPR). 75 FR 
71570. All comments on the fluorescent lamp ballast test procedure 
SNOPR are discussed in section III of this rulemaking.
    As discussed in the SNOPR, DOE has also established a standby mode 
and off mode test procedure. The Energy Independence and Security Act 
of 2007 (Pub. L. 110-140) amended EPCA to require that, for each 
covered product for which DOE's current test procedures do not fully 
account for standby mode and off mode energy consumption, DOE amend the 
test procedures to include standby mode and off mode energy consumption 
into the overall energy efficiency, energy consumption, or other energy 
descriptor for that product. If an integrated test procedure is 
technically infeasible, DOE must prescribe a separate standby mode and 
off mode energy use test procedure, if technically feasible. (42 U.S.C. 
6295(gg)(2)(A)) DOE published a final rule addressing standby mode and 
off mode energy consumption for fluorescent lamp ballasts in the 
Federal Register on October 22, 2009. 74 FR 54445. This final 
rulemaking does not include any changes to the measurement of standby 
and off mode energy consumption for fluorescent lamp ballasts.

General Test Procedure Rulemaking Process

    Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures 
DOE must follow when prescribing or amending test procedures for 
covered products. EPCA requires that any test procedures prescribed or 
amended under this section be reasonably designed to produce test 
results that measure energy efficiency, energy use 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. Test 
procedures must also not be unduly burdensome to conduct. (42 U.S.C. 
6293(b)(3))
    In addition, if DOE determines that a test procedure amendment is 
warranted, it must publish proposed test procedures and offer the 
public an opportunity to present oral and written comments on them. (42 
U.S.C. 6293(b)(2)) Finally, in any rulemaking to amend a test 
procedure, DOE must determine whether the proposed test procedure would 
alter the measured energy efficiency of any covered product as 
determined under the existing test procedure. (42 U.S.C. 6293(e)(1)) If 
DOE determines that the amended test procedure would alter the measured 
efficiency of a covered product, DOE must amend the applicable energy 
conservation standard accordingly. (42 U.S.C. 6293(e)(2)).
    In today's final rule, DOE institutes a new test procedure that 
measures a different metric than the test procedure at Appendix Q. The 
new metric is the BLE metric described in section III.B.1. The new test 
procedure will be used only with any standards developed or

[[Page 25213]]

revised using data collected with the new test procedure.

II. Summary of the Final Rule

    In this test procedure final rule, DOE amends the current 
procedures for fluorescent lamp ballasts to reduce measurement 
variation and testing burden. These changes eliminate photometric 
measurements and prescribe the use of electrical measurements of a 
lamp-and-ballast system. In addition, this test procedure measures a 
new metric, ballast luminous efficiency (BLE), which more directly 
assesses the electrical losses in a ballast compared to the existing 
ballast efficacy factor (BEF) metric. DOE also establishes a minor 
update to the existing test procedure in appendix Q. The following 
paragraphs summarize these changes.
    In the SNOPR, DOE proposed to measure ballast input power and lamp 
arc power using only electrical measurements of a lamp-and-ballast 
system. Variation in the measured power of a reference lamp was 
minimized by the calculation of ballast luminous efficiency, where BLE 
was equal to total lamp arc power divided by ballast input power. This 
proposal remains unchanged in this final rule. To account for the 
increase in lamp efficacy associated with high-frequency lamp operation 
versus low-frequency, DOE also proposed an adjustment to the BLE of 
low-frequency systems. DOE proposed that low-frequency BLE be 
multiplied by 0.9 to account for the approximately 10% increase in 
lighting efficacy associated with high-frequency lamp operation. For 
the final rule, DOE assigns specific lamp operating frequency 
adjustment factors for each ballast type considered. The adjustment 
factors more accurately approximate the increase in lighting efficacy 
associated with high-frequency lamp operation. In the SNOPR, DOE also 
proposed a method for calculating the ballast factor (BF) of a ballast 
by dividing the measured lamp arc power on the test ballast by the 
measured lamp arc power on a reference ballast. In cases where 
reference ballast operating conditions were unavailable, the SNOPR 
provided a reference lamp power (specific to the ballast type) from 
ANSI standard C78.81-2010 or from empirical results. In this final 
rule, DOE is not defining a BF measurement process because the 
standards NOPR does not use BF to define product classes.
    The final test procedure includes specific provisions for the 
testing of ballasts identified in the proposed scope of coverage for 
the standards NOPR. If the scope of coverage changes in later stages of 
the standards rulemaking, DOE will by rule add or remove provisions 
from the test procedure so that it is consistent with the final scope 
of coverage. See section III.G for further detail.
    In any rulemaking to amend a test procedure, DOE must determine 
whether the proposed test procedure would alter the measured energy 
efficiency of any covered product as determined under the existing test 
procedure. (42 U.S.C. 6293(e)(1)) If DOE determines that the amended 
test procedure would alter the measured efficiency of a covered 
product, DOE must amend the applicable energy conservation standard 
accordingly. (42 U.S.C. 6293(e)(2)) The new test procedure will 
describe the efficiency of a ballast in terms of a new metric, BLE. To 
ensure that the standards developed in the ongoing standards rulemaking 
account for any changes to the test procedure, DOE is developing the 
standards based on the measured BLE generated by the active mode test 
procedure established in this rulemaking. The revised test procedure, 
to be published as Appendix Q1 of 10 CFR part 430 Subpart B, will be 
required concurrent with the compliance date of any upcoming amendments 
to the fluorescent lamp ballast standards. DOE is required by a consent 
decree to issue any amended fluorescent lamp ballast standards by June 
30, 2011.
    Until use of Appendix Q1 is required, manufacturers should continue 
testing these ballasts using the test procedure at Appendix Q to 
determine compliance with existing standards. In the SNOPR, DOE 
proposed to make minor updates to the existing test procedure, 
published at Appendix Q to Subpart B of part 430. The final rule does 
not affect this proposal. DOE is amending the reference to ANSI C82.2-
1984 in the existing test procedure (appendix Q) to ANSI C82.2-2002. 
DOE does not believe the updated standard will impose increased testing 
burden or alter the measured BEF of fluorescent lamp ballasts. The 
amendments to Appendix Q are effective on June 3, 2011, and 
manufacturers may not make any representation regarding fluorescent 
lamp ballast efficiency unless such ballast has been tested in 
accordance with the final rule provisions in Appendix Q after October 
31, 2011. See 42 U.S.C. 6293(c).
    In addition, the test procedures for any ballasts that operate in 
standby mode are also located in Appendix Q. Manufacturers must 
continue to use the standby and off mode procedures in Appendix Q for 
certification purposes at this time. DOE has also included the test 
procedures for any ballasts that operate in standby mode in Appendix 
Q1. When use of the procedures in Appendix Q1 are required for 
certification, manufacturers can continue to use the same procedure in 
Appendix Q1 and will no longer need to refer to Appendix Q for that 
procedure.

III. Discussion

A. Appendix Q Test Procedure

    The ballast test procedure (in Appendix Q to Subpart B of 10 CFR 
part 430 determines the performance of a fluorescent lamp ballast based 
on light output measurements and ballast input power. The metric used 
is called ballast efficacy factor (BEF). BEF is relative light output 
divided by the power input of a fluorescent lamp ballast, as measured 
under test conditions specified in ANSI standard C82.2-1984, or as may 
be prescribed by the Secretary. (42 U.S.C. 6291(29)(C))
    The BEF metric uses light output of the lamp-and-ballast system 
instead of ballast electrical output power in its calculation of the 
performance of a ballast. To measure relative light output, ANSI C82.2-
1984 directs the user to measure the photocell output of the test 
ballast operating a reference lamp and the light output of a reference 
ballast operating the same reference lamp. Dividing photocell output of 
the test ballast system by the photocell output of the reference 
ballast system yields relative light output or ballast factor. 
Concurrent with measuring relative light output, the user is directed 
to measure ballast input power. BEF is then calculated by dividing 
relative light output by input power and multiplying by 100. A ballast 
that produces same light output as another ballast (operating the same 
lamp type and number of lamps) with less input power will have a larger 
BEF.

B. Appendix Q1 Test Procedure--Metric

1. Ballast Luminous Efficiency
    In the SNOPR, DOE proposed a new metric to describe the efficiency 
of a ballast called ballast luminous efficiency (BLE). The BLE metric 
and test procedure were based on the NEMA lamp-based ballast efficiency 
(BE) test procedure considered in the test procedure NOPR. The BLE 
metric is equal to ballast input power divided by the lamp arc power of 
a lamp-and-ballast system. DOE also proposed that for low-frequency 
ballasts the quantity ballast input power divided by lamp arc power be 
multiplied by 0.9 to account for the approximately 10% increase in 
lighting efficacy associated with high-

[[Page 25214]]

frequency lamp operation. In this final rule, DOE establishes lamp 
specific low-frequency adjustment factors to more accurately 
approximate this increase in lighting efficacy. DOE continues to use 
the definition of high frequency in ANSI C82.13-2002, which includes 
ballasts operating at frequencies of 10 kHz or more.
    DOE proposed the BLE test procedure because it reduced measurement 
variation and testing burden compared to the existing test procedure 
and other alternatives. In contrast to BEF and relative system efficacy 
(RSE), the BLE metric could be used to compare the efficiency across 
many different types of ballasts. RSE and BEF can only be used to make 
direct comparisons between ballasts that operate certain lamp types, 
while BLE can be used for comparisons among ballasts that operate all 
lamp types. DOE believed that the use of a lamp-and-ballast system 
allowed the ballast to operate at its natural operating point and would 
more accurately assess ballast performance than other methods in which 
the ballast test load is a resistor. DOE also believed that the use of 
electrical measurements and the calculation of BLE reduced the impact 
of lamp manufacturing variation on the efficiency descriptor compared 
to the existing test procedure.
    NEMA commented on the assignment of an adjustment factor based on 
lamp operating frequency, stating that low frequency should be defined 
as 60 Hertz (Hz) and high frequency should be defined as equal to or 
higher than 25 kHz. NEMA stated that it knows of no ballasts that 
operate between 10 and 25 kHz, and that most ballasts operate above 40 
kHz to avoid frequencies used by other devices between 32 and 40 kHz 
and anti-theft devices above 50 kHz. NEMA also commented that luminaire 
manufacturers have defined a specification for high frequency ballasts 
that avoid frequencies of concern. (NEMA, No. 20 at p. 3 \1\)
---------------------------------------------------------------------------

    \1\ A notation in the form ``NEMA, No. 20 at p. 3'' identifies a 
written comment that DOE has received and has included in the docket 
of this rulemaking or a written docket submission. This particular 
notation refers to a comment: (1) Submitted in writing on December 
27, 2010; (2) in document number 20 in the docket of this 
rulemaking; and (3) appearing on page 3 of the document.
---------------------------------------------------------------------------

    In its test data, DOE identified ten electronic ballasts 
(manufactured by five different companies) that operate between 20 and 
25 kHz, and intends to include these ballasts in the high frequency 
category. These ballasts operate F96T12/ES, F96T8HO, F96T8HO/ES, and 
F96T12HO cold temperature lamps. Therefore, DOE continues to use the 
definition of high frequency provided by ANSI C82.13-2002, which 
includes ballasts operating at frequencies of 10 kHz or more. DOE is 
not changing its proposed definition for low-frequency ballasts, which 
is defined as a ballast that operates at a supply frequency of 50 to 60 
Hz and operates the lamp at the same frequency as the supply.
    Other than the high frequency issue discussed above, comments 
received on the metric changes proposed in the SNOPR were generally 
positive. Though the CA IOUs and NEEA noted their preference for a test 
procedure that continued to relate energy consumption to the light 
output of the lamp and ballast system, they supported the SNOPR 
proposal of lamp-based BLE. The California IOUs (CA IOUs) commented 
that the test procedure proposed in the SNOPR represented a significant 
improvement over the procedure proposed in the NOPR, and the Northwest 
Energy Efficiency Alliance (NEEA) fully supported DOE's proposal of a 
metric and test procedure that focus on the electrical inputs and 
outputs of the ballast. (CA IOUs, No. 19 at p. 1, 2; NEEA, No. 18 at p. 
1, 4) The CA IOUs and NEEA concurred with DOE's observations and 
arguments regarding the drawbacks of the resistor-based test procedure 
and the advantages of the proposed lamp-based ballast efficiency test 
procedure. (CA IOUs, No. 19 at p. 2; NEEA, No. 18 at p. 2) The Natural 
Resources Defense Council (NRDC) also supported DOE's proposal to 
measure lamp arc power rather than using resistor banks to simulate 
lamps because it will yield more accurate and consistent results across 
ballast types. (NRDC, No. 21 at p. 1) The CA IOUs and the NRDC also 
agreed with DOE that the new metric will allow for increased comparison 
among ballasts of different ballast factors and among ballasts intended 
for operation with different numbers of lamps. Both organizations 
believe this will make the new metric more useful in designing and 
implementing rebate programs, and will also make it much easier to set 
standard levels of compliance for government or non-government 
procurement policies that specify high efficiency ballasts. (CA IOUs, 
No. 19 at p. 2; NRDC, No. 21 at p. 1) Based on the general support for 
the BLE metric and its use of lamp loads rather than resistor loads, 
DOE establishes use of the BLE metric in the final rule.
    DOE also received comment on whether the proposed name of the 
metric accurately conveys what ballast properties the metric describes. 
NEEA, the CA IOUs, and NRDC were dissatisfied with the name ``ballast 
luminous efficiency'' suggested for the new metric. The new method 
adjusts the ratio of lamp arc power to ballast input power for low-
frequency ballasts to account for the reduced light output per unit of 
power input for those ballasts but does not involve the measurement of 
light output. These organizations commented that the term ``luminous'' 
suggests the continued use of light output as part of the test 
procedure and is thus misleading. (NEEA, No. 18 at p. 1; CA IOUs, No. 
19 at p. 1; and NRDC, No. 21 at p. 1) NEEA suggested that the alternate 
names ``ballast electrical efficiency'', ``ballast component 
efficiency'', and ``ballast-lamp efficiency'' would be more descriptive 
of the proposed metric since the operating frequency of the ballast is 
an electrical characteristic with inherent lamp/ballast system 
efficiency impacts. (NEEA, No. 18 at p. 1) The CA IOUs suggested the 
names ``ballast lamp efficiency'' and ``ballast arc efficiency'' as 
more accurate conveyors of the basis of the test measurement. (CA IOUs, 
No. 19 at p. 1)
    DOE disagrees with NEEA, NRDC, and the CA IOUs and believes ballast 
luminous efficiency is the best description of the metric. In addition 
to describing electrical losses, the BLE metric also accounts for the 
lamp efficacy difference between low and high frequency operation. The 
term ``luminous'' relates to BLE's treatment of lamp operating 
frequency's impact on lamp efficacy, and the term ``efficiency'' 
relates to BLE's treatment of electrical losses within the ballast. The 
other names suggested do not describe both of these elements. 
Therefore, DOE uses the term ballast luminous efficiency in this final 
rule.
2. BEF to BLE
    In the SNOPR, DOE proposed a method for correlating the existing 
BEF standards to BLE. Part of this correlation includes accounting for 
a frequency adjustment factor (the SNOPR proposed 0.9 for low frequency 
ballasts) DOE included in its BLE proposal. When converting a low-
frequency BEF to BLE, the SNOPR proposed BEF must be multiplied by 0.9 
to convert to BLE. NEMA commented that DOE may be incorrectly using the 
0.9 factor in its calculations of high frequency gains in efficiency. 
NEMA stated that different arc powers specified for high frequency and 
low frequency operation on the same lamp are specified at the same 
light output, which implies that there is no further need to correct 
for high frequency gains because these are already accounted for in the 
different arc power specifications. (NEMA, No.

20 at p. 2) NEMA also commented that DOE multiplied the low frequency 
BLE by 0.9 when it should have divided it by 0.9 to generate the 
required BLE needed to attain the same light output and hence BEF 
because low frequency operation has lower luminous efficacy. (NEMA, No. 
20 at p. 2)
    DOE believes there is some confusion concerning the lamp arc 
wattages and adjustment factor used in the calculation of BLE from BEF. 
A single BEF standard is more stringent for low frequency systems than 
for high frequency systems. Therefore, if the low and high frequency 
system have the same BEF and BF, the quantity lamp arc power divided by 
ballast input power would be larger for the low frequency system than 
for the high frequency system. In DOE's conversion technique, 
multiplication by different reference lamp arc powers results in a 
higher lamp arc power divided by ballast input power quantity for the 
low frequency system. However, DOE has defined BLE to include an 
adjustment factor based on lamp operating frequency. DOE multiplies the 
quantity lamp arc power divided by ballast input power by the 
adjustment factor to calculate BLE. This adjustment factor accounts for 
the difference in lamp efficacy between low and high frequency 
operation (because lamp efficacy cannot be assessed through electrical 
measurements of the ballast). Though the BLE corresponding to a low 
frequency BEF may be smaller than a BLE corresponding to a high 
frequency BEF, the low-frequency BLE is still more stringent because of 
the adjustment factor. The adjustment factor allows a single BLE 
standard to be more stringent for low frequency systems than for high 
frequency systems, consistent with the implications of a single BEF 
standard.
    NEEA stated that while they understand DOE's proposal (and 
industry's assertions) with regard to the ability to derive BEF ratings 
from the proposed BLE ratings, they would like some assurance about the 
continuing availability of the BEF ratings, and the integrity of 
whatever values are reported when they are not certified values. The 
NEEA urged the DOE to establish the appropriate inputs for the 
calculations of other metrics (e.g. BE and BEF) from the measured 
proposed BLE metric before the new test procedure goes into effect. 
(NEEA, No. 18 at p. 2) The CA IOUs and NRDC commented that the SNOPR 
did not contain evidence that DOE has conducted significant testing of 
ballasts to compare their BEF results with their BLE results to confirm 
the accuracy of DOE's proposed method for conversions. These 
organizations recommended that such testing be done before DOE issues 
the NOPR for ballast efficiency standards. (CA IOUs, No. 19 at p. 2; 
NRDC, No. 21 at p. 1)
    The conversion of BEF to BLE and vice versa was necessary for DOE 
to confirm that any proposed standards in the standards rulemaking were 
more stringent than existing standards (i.e., to avoid backsliding), 
consistent with 42 USC 6295(o)(1). The standards rulemaking will 
provide more details on DOE's analysis of backsliding. DOE analyzed its 
BEF to BLE conversion results and presents the comparison in this test 
procedure final rule. DOE converted the tested BLE data for all of its 
test ballasts to BEF using the final rule method of conversion and 
compared the calculated BEF values to measured BEF values. DOE found 
that the average BEF converted from BLE was 2.3 percent higher than the 
average tested BEF. The standard deviation of the population of percent 
differences between converted and tested BEFs was 0.043. DOE believes 
that the variation around this average can be explained by the expected 
variation in the BEF test method and the BLE test method. DOE notes 
that manufacturers and industry members can continue to measure BEF or 
can develop their own conversion methods for use in lighting design. 
DOE also understands that NEMA is independently developing its own BLE 
to BEF conversion technique.

C. Appendix Q1 Test Procedure--Ballast Factor

    In the SNOPR, DOE proposed a method for calculating the ballast 
factor (BF) of a system by dividing the measured lamp arc power on the 
test ballast by the measured lamp arc power on a reference ballast. In 
cases where reference ballast operating conditions were unavailable, 
the SNOPR provided a reference lamp power (specific to the ballast type 
and operating frequency) from an ANSI standard or from empirical 
results. The ballast factor measurement was described in detail in 
section III.D of the SNOPR. Particular lamp and ballast pairings were 
specified for both the BLE and BF measurements.
    Lighting designers commonly use the BF specification to calculate 
the total system lumen output for their projects. NEEA and the CA IOUs 
commented that with the proposed test method, calculation of lamp and 
ballast system lumens by multiplying the rated lamp lumen output by the 
candidate ballast BF would not be valid for lamps that were rated with 
a low frequency reference ballast, such as full wattage 4-foot T8s. 
Both organizations suggested that this problem could be addressed by 
simultaneously updating the reference ballasts for full wattage T8 
lamps to a high frequency ballast but stated that this is probably not 
possible in this rulemaking because a change in the way rated lamp 
lumen output is measured would require a new and separate rulemaking. 
NEEA and the CA IOUs recommended that DOE not change the BF calculation 
method unless it is able to address the stakeholder concerns. (NEEA, 
No. 18 at pp. 2-3; CA IOUs, No. 19 at pp. 3-4)
    The CA IOUs asked for guidance concerning when a reference ballast 
should be used to determine BF versus when a number from the proposed 
Table A (which contains the reference arc power values provided in ANSI 
C78.81-2010 and IEC 60081 Ed. 5.0) could be used for BF calculation, 
and requested more information about how the values in the Table A were 
developed. The CA IOUs also commented that some values in the proposed 
Table A have two significant digits while others have none, and 
suggested this be corrected so all values have the same number of 
significant digits. The CA IOUs suggested DOE conduct research to 
obtain additional reference ballast operating characteristics at both 
low and high frequency for key lamp types that are currently lacking 
this information in ANSI C78.81-2010. This would include high frequency 
reference ballast operating characteristics for F32T8 lamps. (CA IOUs, 
No. 19 at p. 4) NRDC supported the CA IOUs' recommendation to find an 
alternative to Table A. (NRDC, No. 21 at p. 2)
    The CA IOUs agreed with DOE that it is important to measure lamp 
arc power on the test ballast and the reference ballast with the same 
lamp because of manufacturing variation in the lamps, and commented 
that using a fixed denominator would unnecessarily decrease the 
accuracy of the ballast factor test. (CA IOUs, No. 19 at p. 4) NEEA and 
the CA IOUs expressed concern that the proposed test procedure 
introduces variability by forcing a comparison of measured test values 
against fixed integer reference

[[Page 25216]]

lamp arc values in the proposed Table A. (CA IOUs, No. 19 at p. 4) NEEA 
commented that this seemed incongruous with DOE's goal of reducing 
testing variability. NEEA also pointed out that DOE had itself 
expressed reservations about the procedure and agreed with DOE's 
preference for measuring lamp arc power under both reference and test 
ballast/lamp conditions. (NEEA, No. 18 at pp. 2-3)
    NEMA disagreed with NEEA and the CA IOUs, expressing concern about 
DOE's proposal to have BF equal the ratio of measured lamp arc powers 
on test and reference ballasts, stating that ballasts will respond to 
each lamp differently because every lamp has a characteristic power 
output. NEMA also commented that determining a reference lamp by light 
output and not a predetermined wattage introduces photometric 
variation, and suggested use of a predetermined wattage to give a BF of 
one from which everything should be determined. NEMA commented that if 
a center point wattage across all manufacturers' lamps were found, it 
should be the value used for BF equal to one. NEMA suggested this 
wattage could be 29 W for a full-wattage 32 W T8 lamp operated on a 
high frequency electronic ballast. NEMA recognized that variations in 
reference lamp parameters will affect BF calculations in some cases, 
but stated that the error introduced into a BF calculation by the 
variations should not be enough to influence which classification a 
ballast design falls into. (NEMA, No. 20 at p. 3)
    The CA IOUs expressed concern that DOE's proposal to change the way 
BF is calculated has not been adequately vetted by the lighting 
industry. The CA IOUs commented on the lack of evidence that DOE has 
conducted significant testing to compare the proposed ballast factor 
correction method with the current one, and suggested DOE conduct the 
testing and publish the results to demonstrate the impacts of the new 
procedure. (CA IOUs, No. 19 at p. 3) The CA IOUs also commented that 
significant change to the ballast factor metric could affect its 
utility in lighting design, and recommended that DOE schedule a public 
meeting in early 2011 to discuss this issue. NEEA stated that lighting 
designers, who will be the most affected by the ballast factor 
calculation change, have not been sufficiently included in the 
discussion. NEEA and the CA IOUs suggested that DOE consult 
representatives of the International Association of Lighting Designers 
(IALD) and the Illuminating Engineering Society of North America 
(IESNA). (NEEA, No. 18 at p. 3; CA IOUs, No 19 at p. 3)
    DOE believes there may have been some misunderstanding of the SNOPR 
BF calculation method. If a candidate ballast operates at high 
frequency, then a high frequency reference arc power value would be 
used to calculate ballast factor. If the candidate ballast operates at 
low frequency, then a low frequency reference lamp arc power value 
would be used. In addition, DOE proposed that if ANSI C78.81 provided 
reference ballast operating conditions at the same frequency as the 
candidate ballast, then the reference lamp arc power value could be 
measured directly. Based on these proposals, reference lamp arc power 
values always correspond to the same operating frequency as the 
candidate ballast. Nevertheless, in the fluorescent lamp ballast 
standards NOPR, DOE proposed a new product class structure that no 
longer makes use of BF. (76 FR 20090, April 11, 2011) In this final 
rule, therefore, DOE is not prescribing a BF measurement methodology. 
DOE notes that manufacturers and industry members can continue to 
measure BF using their preferred methods depending on the demands of 
the market and industry.

D. Appendix Q1 Test Procedure--Requirements

1. Test Conditions
    In the SNOPR, DOE proposed that testing be conducted at 25 degrees 
Celsius  2.0 degrees and in a draft-free environment 
according to ANSI C78.375-1997.\2\ These conditions provide for mostly 
uniform electrical operating characteristics for the lamp-and-ballast 
system. In addition, DOE proposed that ballasts be tested using the 
electrical supply characteristics found in section 4 of ANSI C82.2-2002 
with the following changes: (1) Ballasts capable of operating at a 
single voltage would be tested at the rated ballast input voltage; (2) 
users of universal voltage ballasts would disregard the input voltage 
directions in section 4.1 of ANSI C82.2-2002 that indicate a ballast 
capable of operating at multiple voltages should be tested at both the 
lowest and highest USA design center voltage; and (3) manufacturers use 
particular revisions to the normative references associated with ANSI 
C82.2-2002 (see section III.D.6 for additional detail). Instead of 
testing universal voltage ballasts at the voltages indicated in ANSI 
C82.2-2002, DOE proposed that testing ballasts at a single voltage 
would be more appropriate and less burdensome. DOE noted that 277 V is 
the most common input voltage for commercial ballasts and that 120 V is 
the most common for residential ballasts and commercial cold-
temperature outdoor sign ballasts. Therefore, DOE proposed that all 
universal voltage commercial ballasts be tested at 277 V and that 
universal voltage residential and commercial cold-temperature outdoor 
sign ballasts be tested at 120 V.
---------------------------------------------------------------------------

    \2\ ``American National Standard for Fluorescent Lamps--Guide 
for Electrical Measurements,'' approved September 25, 1997.
---------------------------------------------------------------------------

    The CA IOUs approved of DOE's proposal that the BLE calculation for 
universal voltage commercial ballasts be based on testing at 277 volts 
and testing of universal voltage residential ballasts and outdoor cold 
temperature sign ballasts be conducted at 120 volts. They believe this 
will add clarity to the test procedure because the value reported for 
compliance purposes is now specified. However, the CA IOUs commented 
that manufacturers of universal voltage ballasts should be required to 
publish input wattage for operation at both the upper and lower range 
of universal voltage ballasts in their product literature because some 
commercial spaces have 120 volt service in significant portions of the 
building, such as bathrooms. Since input watts can vary by one to two 
watts depending on the voltage, the CA IOUs believe it would be useful 
in lighting design to consider input watts at both 277 and 120 volts. 
(CA IOUs, No. 19 at pp. 2-3)
    Because DOE has not received adverse comment to its test conditions 
proposal in the SNOPR, the test condition requirements for this final 
rule are unchanged. With regards to the comment concerning the 
publication of input wattage for operation at both the upper and lower 
range of universal voltage ballasts, the Federal Trade Commission has 
statutory authority to establish labeling requirements for fluorescent 
lamp ballasts. Manufacturers are also prohibited from making any 
representation regarding the energy efficiency of a product unless the 
product has been tested according to the DOE test procedure and the 
representation fairly discloses the results of such testing. (42 U.S.C. 
6293(c)).
2. Test Setup
    NEEA, the CA IOUs, and NRDC supported the proposed method of test 
wiring for programmed and rapid start ballasts without cathode cut-out. 
These organizations concurred with DOE's observation that the proposed 
procedure isolates lamp arc voltage by capturing heating energy in the 
input power measurement, but not in the output

[[Page 25217]]

power measurement, and will appropriately measure the relative 
efficiency of ballasts with cathode heating. (NEEA, No. 18 at p. 2; CA 
IOUs, No. 19 at p. 2; and NRDC, No. 21 at p. 2) Based on the comments 
received in support of the SNOPR test setup proposal, the setup 
required in the final rule does not change.
    DOE is adding one clarification to its SNOPR setup proposal with 
regards to the lamp type paired with sign ballasts. In the SNOPR, DOE 
proposed that all ballasts, including sign ballasts, be tested with the 
most common wattage lamp typically used with that ballast type. For 
sign ballasts, DOE identified 110 W 8-foot T12 lamps and 86 W 8-foot T8 
lamps as being the most common. However, DOE notes that some sign 
ballasts are capable of operating both T12 and T8 lamps. Based on 
interviews with manufacturers, DOE believes the T12 lamp pairing is the 
most common. Therefore, in the final rule, sign ballasts capable of 
operating T12 and T8 lamps shall be paired with a 110 W 8-foot T12 lamp 
for the purposes of determining compliance with energy conservation 
standards. Sign ballasts capable of only operating T8 or only T12 lamps 
shall be operated with the diameter lamp they are designed to operate.
3. Test Method
    The test method required in the final rule is unchanged from the 
SNOPR proposal. Once the lamp-and-ballast system is connected and 
attached to the measurement instrumentation, the ballast must operate a 
fluorescent lamp for a minimum of fifteen minutes to a maximum of one 
hour until stability is reached. Measurements of lamp arc voltage, lamp 
arc current, and lamp arc power must be taken every one second during 
the stabilization period. Once the percent difference between the 
minimum and maximum values for voltage, current, and power do not 
exceed one percent over a four minute moving window, the system is 
considered stable. Allowing the lamp and ballast system to reach its 
steady state operating point will provide a more accurate assessment of 
ballast performance in the field. If the system does not stabilize, a 
new ballast sample is selected and the test is repeated.
    After the system has stabilized, the measured input parameters are 
voltage (RMS \3\), current (RMS), power, and power factor measured in 
accordance with ANSI C82.2-2002. The measured output parameters include 
lamp arc voltage, current, and power. Lamp arc current and voltage 
measurements are taken at the specified locations according to the test 
setup. Frequency of the output waveform delivered to the lamp by the 
ballast is also measured.
---------------------------------------------------------------------------

    \3\ Root mean square (RMS) voltage is a statistical measure of 
the magnitude of a voltage signal. RMS voltage is equal to the 
square root of the mean of all squared instantaneous voltages over 
one complete cycle of the voltage signal.
---------------------------------------------------------------------------

    NEMA commented that a text correction is needed on page 71578 of 
the SNOPR, in the section describing lamp arc voltage measurement in 
the test circuit setup. DOE stated that during lamp arc voltage 
measurement, it is assumed the arc begins near the center of the 
ballast cathodes. The sentence should read: ``The voltage divider would 
provide a position in the circuit to measure the lamp arc voltage 
assuming the arc begins near the center of the lamp (instead of 
ballast) cathodes.'' (NEMA, No. 20 at p. 4) DOE agrees with NEMA that 
the sentence should have referenced lamp cathodes rather than ballast 
cathodes.
4. Calculations
    As described in Equation 1 below, ballast luminous efficiency is 
equal to total lamp arc power, divided by ballast input power, 
multiplied by 100, and then multiplied by a lamp operating frequency 
correction factor ([beta]).
[GRAPHIC] [TIFF OMITTED] TR04MY11.011

    In the SNOPR, DOE proposed that the symbol [beta] be equal to 0.9 
for low-frequency ballasts and equal to 1.0 for high-frequency 
ballasts. NEMA commented that because the 0.9 correction factor for low 
frequency ballasts is based on the IESNA handbook reference to F40T12 
lamps, it should not be applied broadly to all lamp types. The 10 
percent gain for the F40T12 is due to a decrease in ``end losses'' and 
an increase in column efficacy due to a lower operating power. NEMA 
commented that the proportional gain in efficacy due to decreased ``end 
losses'' will be different for different lamp types because of 
differences in column voltage. Additionally, the increase in column 
efficacy from a reduction in column power may not apply to all other 
lamps. NEMA stated that it would submit additional comments after it 
had time to verify if a 0.93 correction factor would be appropriate for 
T8 lamps, and that no correction factor should be needed for T5 lamps 
because they are designed only for high frequency operation. DOE did 
not receive these additional comments from NEMA on appropriate 
frequency adjustment factors. Finally, NEMA stated that for ballasts 
meeting ANSI C82.11 and C82.1, there should be no other appreciable 
effect on fluorescent lamp efficacy from lamp current crest factor, 
wave form, and lamp operating frequency. (NEMA, No. 20 at pp. 2-3)
    The CA IOUs and NRDC stated that DOE's proposal to apply a factor 
of 0.9 to the efficiency measurements of low frequency ballasts is an 
acceptable proxy for light measurements to assess the benefits of high 
frequency operation. The CA IOUs commented that they do not have data 
to indicate that the variation in lamp light output due to variations 
in crest factor or wave shape during high frequency operation is 
significant. (CA IOUs, No. 19 at p. 2 and NRDC, No. 21 at p. 2)
    In light of NEMA's comments, DOE establishes different low 
frequency correction factors for the different lamp types operated by 
ballasts within the scope of this final rule. DOE believes that these 
factors more accurately represent the difference in arc power between 
high frequency and low frequency operation for the same light output. 
The adjustment factor is equal to high frequency lamp arc power divided 
by low frequency lamp arc power--specific to each lamp type. DOE used 
ANSI lamp data when available and empirical data when it was not. To 
derive correction factors for when ANSI lamp data is unavailable for 
both high and low frequency, DOE operated a lamp using the ANSI 
reference ballast settings at the given rating frequency (either high 
or low frequency) and recorded the light output. DOE then switched the 
same lamp to a reference ballast of the frequency type not provided by 
ANSI and adjusted the ballast settings to match the light output

[[Page 25218]]

with the output obtained using the first ballast. DOE recorded the lamp 
arc power once the light output was matched.

5. Updates to Existing Test Procedure
    DOE is not changing the proposed updates to the existing test 
procedure from the SNOPR in this final rule. DOE is updating the 
references to ANSI standards for the existing light-output-based test 
procedure. DOE is using the most recent versions of these standards, 
namely ANSI C82.2-2002, ANSI C82.11-2002 \4\, and ANSI C82.1-2004. The 
amendments to the existing test procedure in Appendix Q to Subpart B of 
10 CFR part 430 will be effective 30 days after publication of the test 
procedure final rule.
---------------------------------------------------------------------------

    \4\ ``American National Standards for Lamp Ballasts--High 
Frequency Lamp Ballasts--Supplements,'' approved January 17, 2002.
---------------------------------------------------------------------------

6. Normative References for ANSI C82.2-2002
    DOE is not changing its proposals regarding the specification of 
normative references to be used with ANSI C82.2-2002 from the SNOPR in 
this final rule. DOE is amending the existing fluorescent lamp ballast 
test procedure in Appendix Q to incorporate references to ANSI C82.2-
2002 and including references to ANSI C82.2-2002 in the new appendix 
Q1. In examining the ANSI standard, DOE found that within ANSI C82.2-
2002, there are references to other ANSI standards. In particular, 
section 2 of ANSI C82.2-2002 states that ``when American National 
Standards referred to in this document [ANSI C82.2-2002] are superseded 
by a revision approved by the American National Standards Institute, 
Inc. the revision shall apply.'' Revisions to these normative standards 
could potentially impact compliance with energy conservation standards 
by changing the tested value for energy efficiency. Therefore, DOE is 
specifying the particular versions of the ANSI standards that will be 
used in conjunction with ANSI C82.2-2002. DOE is using ANSI C78.81-
2010, ANSI C82.1-2004, ANSI C82.11-2002, and ANSI C82.13-2002 in 
support of ANSI C82.2-2002. All other normative references are as 
directly specified in ANSI C82.2-2002. These specifications will apply 
to the ANSI C82.2-2002 references in Appendix Q and to the ANSI C82.2-
2002 references in Appendix Q1.

E. Burden To Conduct the Test Procedure

    EPCA requires that any test procedures prescribed or amended under 
this section be reasonably designed to produce test results that 
measure energy efficiency, energy use or estimated annual operating 
cost of a covered product during a representative average use cycle or 
period of use. Test procedures must also not be unduly burdensome to 
conduct.'' (42 U.S.C. 6293(b)(3)). Today's final test procedure 
measures the performance of a ballast by computing the ratio of lamp 
arc power to ballast input power and adjusting for lamp operating 
frequency. The test procedure is less burdensome than the existing 
procedure largely because of the simplicity of electrical measurements 
compared to photometric measurements. In addition, the lamp loads are 
less expensive than precision resistor loads proposed in the NOPR and 
are already a common item used in test facilities. The assessment of 
testing burden is discussed in more detail with reference to small 
businesses in section IV.B. NEEA commented that it was

[[Page 25219]]

pleased with the basics of the proposed test procedure and supported a 
test procedure that does not unduly burden manufacturers. (NEEA, No. 18 
at p. 1)
    To further ensure that the test procedure in this final rule is not 
unduly burdensome to conduct, DOE is not changing the minimum sample 
size (four) for generating a reported value or to the reported value 
itself. Currently, to demonstrate compliance with energy conservation 
standards, manufacturers must first test four examples of the basic 
model. The reported value of BLE is then equal to either the lower 99% 
confidence interval limit divided by 0.99 or the mean of the four 
values, whichever is smaller.

F. Impact on Measured Energy Efficiency

    In any rulemaking to amend a test procedure, DOE must determine 
whether the proposed test procedure would alter the measured energy 
efficiency of any covered product as determined under the existing test 
procedure. (42 U.S.C. 6293(e)(1)) If DOE determines that the amended 
test procedure would alter the measured efficiency of a covered 
product, DOE must amend the applicable energy conservation standard 
accordingly. (42 U.S.C. 6293(e)(2)) This final rule active mode test 
procedure changes the metric used to describe the energy efficiency of 
a ballast. DOE is currently amending energy conservation standards for 
fluorescent lamp ballasts in the standards rulemaking. In that 
rulemaking, DOE is considering standards based on the measured 
efficiency of the ballast in accordance with the test procedure 
prescribed in this active mode test procedure rulemaking. The BLE test 
procedure final rule will not affect compliance with existing energy 
conservation standards because manufacturers will not be required to 
use the new test procedure until the date manufacturers are required to 
comply with any amended standards.

G. Scope of Applicability

    Today's test procedure final rule is applicable to the fluorescent 
lamp ballasts covered in the proposed scope of coverage outlined in the 
fluorescent lamp ballast standard NOPR, which includes ballasts that 
operate F32T8, F34T12, F28T5SO, F54T5HO, F96T8/ES, F96T12/ES, F96T8HO, 
F96T12HO/ES, and F96T12HO lamps. 76 FR 20090 (April 11, 2011). These 
ballasts can operate between one and six lamps and are used in 
commercial, residential, and cold-temperature outdoor sign 
applications. For the test procedure in this rulemaking, DOE is 
establishing particular test setups and calculations depending on type 
of ballast, as described in more detail in section III.D. For example, 
DOE is specifying certain fluorescent lamps and numbers of these lamps 
to be paired with certain ballasts for determining ballast performance.

H. Certification and Enforcement

    In the test procedure SNOPR, DOE proposed the measurement of BLE 
using electrical measurements of a lamp and ballast system. DOE 
believes this test procedure to be clearer and less burdensome to 
conduct compared to the existing method which may result in increased 
compliance. DOE also proposed that test facilities conducting 
compliance testing in accordance with amended standards promulgated by 
the ongoing standards rulemaking be National Volunteer Laboratory 
Accreditation Program (NVLAP) accredited, a program administered by the 
National Institute of Standards and Technology (NIST), or accredited by 
an organization recognized by NVLAP.
    NVLAP accreditation is a finding of laboratory competence, 
certifying that a laboratory operates in accordance with NVLAP 
management and technical requirements. The NVLAP program is described 
in 15 CFR part 285, and encompasses the requirements of ISO/IEC 
17025.\5\ NVLAP (or an organization recognized by NVLAP) accreditation 
is currently required for laboratories providing certification and 
compliance data for general service fluorescent, general service 
incandescent, and incandescent reflector lamps. In the SNOPR, DOE 
stated that either of these accreditation requirements would ensure 
that all the data DOE uses in its rulemaking comes from standardized 
and quality controlled sources, increasing confidence in the precision 
of the data and limiting variations due to differences between testing 
laboratories. DOE determined that NVLAP imposes fees of $9000 and $8000 
on years one and two of accreditation. For the years following, the 
fees alternate between $5000 and $8000, with the $8000 fee 
corresponding to the on-site evaluation required every other year. Fees 
for other accreditation organizations are expected to be similar. DOE 
invited comment on the benefits and burden imposed by the requirement 
that certification and compliance data come from an NVLAP or NVLAP 
recognized organization accredited laboratory.
---------------------------------------------------------------------------

    \5\ International Organization for Standardization/International 
Electrotechnical Commission, General requirements for the competence 
of testing and calibration laboratories. ISO/IEC 17025.
---------------------------------------------------------------------------

    NEMA agreed with DOE that there should be an accreditation 
requirement for laboratories generating certification and compliance 
data, but does not believe NVLAP accreditation or recognition should be 
the only option. NEMA recommended that the accreditation requirements 
should read: ``Laboratory accreditation is by ISO17025 accreditation on 
ballast energy efficiency procedures such as Underwriter Laboratories, 
Council of Canada, etc * * *'' (NEMA, No. 20 at p. 4).
    NEEA and NRDC strongly supported the proposed requirement that all 
certification and compliance testing be done at NVLAP accredited or 
recognized laboratories to establish a testing regime that will produce 
accurate and repeatable results. (NEEA, No. 18 at p. 4 and NRDC, No. 21 
at p. 2) The CA IOUs also agreed with DOE, noting that the overwhelming 
majority of ballasts tested by DOE showed significantly higher measured 
BEFs than their reported catalog values. The CA IOUs believe that 
requiring testing from accredited third party labs will help ensure 
testing consistency. (CA IOUs, No. 19 at p. 5) Earthjustice agreed with 
DOE that requiring NVLAP accreditation or recognition for labs that do 
certification and compliance data will increase the integrity of test 
data, adding that this requirement is especially important given DOE's 
proposal to allow manufacturers to manufacture and test their own 
products. Earthjustice believes that the benefits of the requirement 
outweigh any potential burdens because the added per-unit cost would be 
a negligible fraction of a penny. (Earthjustice, No. 22 at p. 1)
    In this final rule, DOE is amending the laboratory accreditation 
requirements to be by ISO17025 accreditation on ballast energy 
efficiency procedures. Accreditation must be done by NVLAP or a NVLAP-
recognized organization, Underwriter Laboratories, or Council of 
Canada. DOE invites interested parties to suggest whether organizations 
should be added or removed from the list of accepted accrediting bodies 
which could be incorporated in a future test procedure amendment. 
During manufacturer interviews, DOE learned that gaining NVLAP 
accreditation could take between six months and two years. This final 
rule imposes laboratory accreditation requirements only for compliance 
testing using Appendix Q1.

IV. Procedural Issues and Regulatory Review

A. Review Under Executive Order 12866

    The Office of Management and Budget has determined that test 
procedure rulemakings do not constitute ``significant regulatory 
actions'' under section 3(f) of Executive Order 12866, Regulatory 
Planning and Review, 58 FR 51735 (Oct. 4, 1993). Accordingly, this 
action was not subject to review under the Executive Order by the 
Office of Information and Regulatory Affairs (OIRA) in the Office of 
Management and Budget (OMB).

B. Review Under the Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires 
preparation of an initial regulatory flexibility analysis (IFRA) for 
any rule that by law must be proposed for public comment, unless the 
agency certifies that the rule, if promulgated, will not have a 
significant economic impact on a substantial number of small entities. 
As required by 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 certified to the Office of Advocacy of the Small Business 
Administration (SBA) that the proposed test procedure for ballasts 
would not have a significant economic impact on a substantial number of 
small entities, and updated that certification in the SNOPR. The 
factual basis for that certification is as follows:
    The SBA has set a size threshold for manufacturers of fluorescent 
lamp ballasts that defines those entities classified as ``small 
businesses'' for the purposes of the Regulatory Flexibility Analysis. 
DOE used the SBA's small business size standards to determine whether 
any small manufacturers of fluorescent lamp ballasts would be subject 
to the requirements of the rule. 65 FR 30836, 30850 (May 15, 2000), as 
amended at 65 FR 53533, 53545 (September 5, 2000) and codified at 13 
CFR part 121. The size standards are listed by North American Industry 
Classification System (NAICS) code and industry description and are 
available at http://www.sba.gov/idc/groups/public/documents/sba_homepage/serv_sstd_tablepdf.pdf. Fluorescent lamp ballast 
manufacturing is classified under NAICS 335311, ``Power, Distribution, 
& Specialty Transformer Manufacturing.'' The SBA sets a threshold of 
750 employees or less for an entity to be considered as a small 
business for this category.
    To identify potential small manufacturers as defined by SBA, DOE 
conducted a market survey using all available public information. DOE's 
research involved several industry trade association membership 
directories, product databases, individual company Web sites, and 
marketing research tools (e.g., Dun and Bradstreet reports) to create a 
list of every company that manufactures or sells fluorescent lamp 
ballasts covered by this rulemaking. DOE reviewed all publicly-
available data and contacted companies on its list, as necessary, to 
determine whether they met the SBA's definition of a small business 
manufacturer of covered fluorescent lamp ballasts. DOE screened out 
companies that did not offer fluorescent lamp ballasts covered by this 
rulemaking, did not meet the definition of a ``small business,'' or are 
foreign owned and operated. Ultimately, DOE identified approximately 10 
fluorescent lamp ballast manufacturers that produce covered fluorescent 
lamp ballasts and can potentially be considered small businesses out of 
the at least 54 ballast manufacturers identified in the fluorescent 
lamp ballast standards NOPR.
    The final rule includes revisions to appendix Q and a new appendix 
Q1. The revisions to appendix Q update an industry reference and do not 
change the test method or increase testing burden. The only difference 
between the two test procedures relates to the interference of testing 
instrumentation. Specifically, the input power measurement of ANSI 
C82.2-2002 reduces the interference of instrumentation on the input 
power measurement as compared to ANSI C82.2-1984. The vast majority of 
companies and testing facilities, however, already employ modern 
instrumentation that does not significantly interfere with input power 
measurements. Thus, updating this industry reference would not impose 
additional financial burden in terms of labor or materials. As 
described in more detail in section III.D, the amended test procedure 
for appendix Q1 is generally less burdensome compared to the existing 
test procedure, while reducing measurement variation. This procedure 
uses only electrical measurements which are generally simpler and more 
quickly carried out than photometric measurements. The final test 
procedure only uses a reference ballast once every 24 hours, rather 
than during the performance evaluation of each individual ballast. This 
change reduces the number of measurements necessary for assigning a BLE 
to a ballast compared to the number of measurements necessary for BEF 
under the existing test procedure. In addition, the final test method 
specifies a shorter lamp seasoning period (12 hours versus 100 hours) 
because the lamp's electrical characteristics stabilize sooner than its 
photometric characteristics.
    To analyze the testing burden impacts described above on small 
business manufacturers, DOE first sought to examine publically 
available financial data for those companies identified as small 
businesses to compare the estimated revenue and profit of these 
businesses to the anticipated testing burden associated with this final 
test procedure. In the SNOPR, DOE determined that all the identified 
small business manufacturers were privately owned, and as a result, 
financial data was not publically available. DOE estimates that the 
incremental testing costs for an average small business would be no 
more and likely less than testing costs under the existing BEF test 
procedure for the reasons set forth in the following paragraph.
    The BLE procedure requires no additional equipment compared to the 
existing test procedure and eliminates the usage of photocells or an 
integrating sphere. In addition, the existing BEF test procedure 
requires measurements of lamp light output on a reference ballast and 
measurements on a test ballast during each test. Light output 
measurements and electrical measurements of the reference system can 
require one to two hours depending on the number of reference ballasts 
available and the speed at which the lamp reaches photometric 
stability. Light output and electrical measurements of the test ballast 
are taken immediately after switching the lamps from the reference to 
the test system. In contrast, the BLE procedure in this final rule 
requires the reference lamps to be measured and stabilized on a 
reference ballast only once every twenty four hours. After this 
stabilization, subsequent testing of the ballasts of interest can take 
between 15 and 60 minutes. In the SNOPR, DOE estimated that between 4 
and 8 ballast samples could be completed in an eight hour period using 
the existing BEF test procedure, while between 8 and 16 tests could be 
completed using the BLE test procedure. Therefore, DOE estimated the 
BLE procedure could result in an

[[Page 25221]]

incremental reduction in testing time of about 50%. Assuming the labor 
rate for carrying out either procedure is $100 per hour, the BLE 
procedure could reduce testing costs by $50 to $100 dollars per test. 
DOE noted that depending on setup, some facilities may see less of a 
reduction in testing time or potentially no change in testing time. 
Finally, as presented in the SNOPR, DOE believes the cost of test 
laboratory accreditation is approximately $8000 per year, which DOE 
believes would not be a significant impact.
    On the basis of the foregoing, DOE concluded that this final rule 
would not have a significant impact on a substantial number of small 
entities. Accordingly, DOE has not prepared a regulatory flexibility 
analysis for this rulemaking. DOE has provided its certification and 
supporting statement of factual basis to the Chief Counsel for Advocacy 
of the Small Business Administration for review under 5 U.S.C. 605(b).

C. Review Under the Paperwork Reduction Act of 1995

    Manufacturers of fluorescent lamp ballasts must certify to DOE that 
their product complies with any applicable energy conservation 
standard. In certifying compliance, manufacturers must test their 
product according to the DOE test procedure for fluorescent lamp 
ballasts, including any amendments adopted for that test procedure. DOE 
has proposed regulations for the certification and recordkeeping 
requirements for all covered consumer products and commercial 
equipment, including fluorescent lamp ballasts. 75 FR 56796 (Sept. 16, 
2010). The collection-of-information requirement for the certification 
and recordkeeping has been approved by OMB under control number 1910-
1400. As described in the NOPR, the public reporting burden for the 
certification is estimated to average 20 hours per response, including 
the time for reviewing instructions, searching existing data sources, 
gathering and maintaining the data needed, and completing and reviewing 
the collection of information.
    Public comment is sought regarding: whether this proposed 
collection of information is necessary for the proper performance of 
the functions of the agency, including whether the information shall 
have practical utility; the accuracy of the burden estimate; ways to 
enhance the quality, utility, and clarity of the information to be 
collected; and ways to minimize the burden of the collection of 
information, including through the use of automated collection 
techniques or other forms of information technology. Send comments on 
these or any other aspects of the collection of information to Tina 
Kaarsberg (see ADDRESSES) and by e-mail to Christine_J._Kymn@omb.eop.gov.
    Notwithstanding any other provision of the law, no person is 
required to respond to, nor shall any person be subject to a penalty 
for failure to comply with, a collection of information subject to the 
requirements of the PRA, unless that collection of information displays 
a currently valid OMB Control Number.

D. Review Under the National Environmental Policy Act of 1969

    In this final rule, DOE amends its test procedure for fluorescent 
lamp ballasts. DOE has determined that this rule falls into a class of 
actions that are categorically excluded from review under the National 
Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.) and DOE's 
implementing regulations at 10 CFR part 1021. Specifically, this rule 
amends an existing rule without affecting the amount, quality or 
distribution of energy usage, and, therefore, will not result in any 
environmental impacts. Thus, this rulemaking is covered by Categorical 
Exclusion A5 under 10 CFR part 1021, subpart D, which applies to any 
rulemaking that interprets or amends an existing rule without changing 
the environmental effect of that rule. Accordingly, neither an 
environmental assessment nor an environmental impact statement is 
required.

E. Review Under Executive Order 13132

    Executive Order 13132, ``Federalism,'' 64 FR 43255 (August 4, 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 Executive Order also requires 
agencies to have an accountable process to ensure meaningful and timely 
input by State and local officials in the development of regulatory 
policies that have Federalism implications. On March 14, 2000, DOE 
published a statement of policy describing the intergovernmental 
consultation process it will follow in the development of such 
regulations. 65 FR 13735. DOE examined this final rule and determined 
that it will not have a substantial direct effect on the States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government. EPCA governs and prescribes Federal preemption of State 
regulations as to energy conservation for the products that are the 
subject of today's final rule. States can petition DOE for exemption 
from such preemption to the extent, and based on criteria, set forth in 
EPCA. (42 U.S.C. 6297(d)) No further action is required by Executive 
Order 13132.

F. Review Under 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 (Feb. 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; (3) provide a clear legal standard for affected 
conduct rather than a general standard; and (4) promote simplification 
and burden reduction. 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 them. DOE has completed the 
required review and determined that, to the extent permitted by law, 
this final rule meets the relevant standards of Executive Order 12988.

G. Review Under the Unfunded Mandates Reform Act of 1995

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) 
requires each Federal agency to assess the effects of Federal 
regulatory actions on State, local, and Tribal governments and the 
private sector. Public Law 104-4, sec. 201 (codified at 2 U.S.C. 1531). 
For a regulatory action resulting in a rule that may cause the 
expenditure by State, local, and Tribal governments, in the

[[Page 25222]]

aggregate, or by the private sector of $100 million or more in any one 
year (adjusted annually for inflation), section 202 of UMRA requires a 
Federal agency to publish a written statement that estimates the 
resulting costs, benefits, and other effects on the national economy. 
(2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to 
develop an effective process to permit timely input by elected officers 
of State, local, and Tribal governments on a proposed ``significant 
intergovernmental mandate,'' and requires an agency plan for giving 
notice and opportunity for timely input to potentially affected small 
governments before establishing any requirements that might 
significantly or uniquely affect small governments. 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. DOE examined today's final rule according to 
UMRA and its statement of policy and determined that the rule contains 
neither an intergovernmental mandate, nor a mandate that may result in 
the expenditure of $100 million or more in any year, so these 
requirements do not apply.

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

    Section 654 of the Treasury and General Government Appropriations 
Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family 
Policymaking Assessment for any rule that may affect family well-being. 
Today's final rule will not have any impact on the autonomy or 
integrity of the family as an institution. Accordingly, DOE has 
concluded that it is not necessary to prepare a Family Policymaking 
Assessment.

I. Review Under Executive Order 12630

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

J. Review Under Treasury and General Government Appropriations Act, 
2001

    Section 515 of the Treasury and General Government Appropriations 
Act, 2001 (44 U.S.C. 3516 note) provides for 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 (Feb. 22, 2002), and 
DOE's guidelines were published at 67 FR 62446 (Oct. 7, 2002). DOE has 
reviewed today's final rule under the OMB and DOE guidelines and has 
concluded that it is consistent with applicable policies in those 
guidelines.

K. Review Under Executive Order 13211

    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 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 significant energy action, the 
agency must give a detailed statement of any adverse effects on energy 
supply, distribution, or use if the regulation is 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. Moreover, it would not have a significant 
adverse effect on the supply, distribution, or use of energy, nor has 
it been designated as a significant energy action by the Administrator 
of OIRA. Therefore, it is not a significant energy action, and, 
accordingly, DOE has not prepared a Statement of Energy Effects.

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

    Under section 301 of the Department of Energy Organization Act 
(Pub. L. 95-91; 42 U.S.C. 7101), DOE must comply with section 32 of the 
Federal Energy Administration Act of 1974, as amended by the Federal 
Energy Administration Authorization Act of 1977. (15 U.S.C. 788; FEAA) 
Section 32 essentially provides in relevant part 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. In addition, section 32(c) requires DOE to consult with 
the Attorney General and the Chairman of the Federal Trade Commission 
(FTC) concerning the impact of the commercial or industry standards on 
competition.
    This final test procedure incorporates testing methods contained in 
the following commercial standards: ANSI C78.81-2010, Revision of ANSI 
C78.81-2005 (``ANSI C78.81-2010''), American National Standard for 
Electric Lamps--Double-Capped Fluorescent Lamps--Dimensional and 
Electrical Characteristics; ANSI C82.1-2004, Revision of ANSI C82.1-
1997 (``ANSI C82.1''), American National Standard for Lamp Ballast--
Line-Frequency Fluorescent Lamp Ballast; ANSI C82.2-2002, Revision of 
ANSI C82.2-1994 (R1995), American National Standard for Lamp Ballasts-
Method of Measurement of Fluorescent Ballasts; ANSI C82.11-2002, 
Revision of ANSI C82.11-1993 (``ANSI C82.11''), American National 
Standard for Lamp Ballasts--High-frequency Fluorescent Lamp Ballasts; 
ANSI C82.13-2002 (``ANSI C82.13''), American National Standard for Lamp 
Ballasts--Definitions for Fluorescent Lamps and Ballasts; ANSI C78.375-
1997, Revision of ANSI C78.375-1991 (``ANSI C78.375''), American 
National Standard for Fluorescent Lamps--Guide for Electrical 
Measurements, first edition; ANSI C82.3-2002, Revision of ANSI C82.3-
1983 (R 1995) (``ANSI C82.3''), American National Standard for 
Reference Ballasts for Fluorescent Lamps. DOE has evaluated these 
standards and was unable to conclude whether they fully comply with the 
requirements of section 32(b) of the FEAA (i.e. whether it was 
developed in a manner that fully provides for public participation, 
comment, and review.) DOE has consulted with both the Attorney General 
and the Chairman of the FTC about the impact on competition of using 
the methods contained in these standards and has received no comments 
objecting to their use.

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. 804(2).

N. Approval of the Office of the Secretary

    The Secretary of Energy has approved publication of this final 
rule.

3. Standby Mode Procedure

    3.1. The measurement of standby mode power need not be performed 
to determine compliance with energy conservation standards for 
fluorescent lamp ballasts at this time. The above statement will be 
removed as part of a rulemaking to amend the energy conservation 
standards for fluorescent lamp ballasts to account for standby mode 
energy consumption, and the following shall apply on the compliance 
date for such requirements.

3.2. Test Conditions

    3.2.1. The test conditions for testing fluorescent lamp ballasts 
shall be done in accordance with the American National Standard 
Institute ANSI C82.2 (incorporated by reference; see Sec.  430.3). 
Any subsequent amendment to this standard by the standard-setting 
organization will not affect the DOE test procedures unless and 
until amended by DOE. The test conditions for measuring standby 
power are described in sections 5, 7, and 8 of ANSI C82.2. 
Fluorescent lamp ballasts that are capable of connections to control 
devices shall be tested with all commercially available compatible 
control devices connected in all possible configurations. For each 
configuration, a separate measurement of standby power shall be made 
in accordance with section 3.3 of the test procedure.

3.3. Test Method and Measurements

    3.3.1. The test for measuring standby mode energy consumption of
