AHAM requested that DOE stay the effectiveness of the test procedure 
final rule and final standards rule until DOE either: (1) Revises the 
standards in the final standards rule to account for the impact on 
measured energy resulting from test procedure amendments to measure 
fan-only mode and standby and off mode energy use; or (2) delays 
requirements regarding measurement of fan-only mode and standby and off 
mode energy use until promulgation of a revised standard for 
dishwashers. After carefully considering AHAM's request and the 
comments submitted in response to publication of the petition for 
comment, DOE declines to grant the request.

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

I. AHAM Petition Summary

    In support of its request, AHAM asserts that the test procedure 
amendments for fan-only mode and standby and off mode energy use impact 
the measured energy use of dishwashers. As a result, AHAM states that 
the Energy Policy and Conservation Act of 1975 (EPCA), as amended, 
requires DOE to adjust the stringency of the energy conservation 
standards in the direct final rule accordingly or delay compliance with 
those test procedure amendments until a subsequent amended standard is 
promulgated for dishwashers. AHAM acknowledges that the standards 
established in the direct final rule were submitted to DOE in a 
consensus agreement to which it was a party and adopted pursuant to 
DOE's authority at 42 U.S.C. 6295(p)(4).

A. Fan-Only Mode

    In support of AHAM's contention that the fan-only mode test 
procedure revisions require an adjustment of the standard, AHAM cited 
DOE's conclusion that measurement of fan-only mode energy use would 
increase the measured energy use of the dishwasher by 0.4-17 kilowatt-
hours per year (kWh/year). In addition, AHAM cited a statement from a 
supplemental notice of proposed rulemaking (SNOPR) that the higher end 
of the range is greater than 5 percent of the maximum allowable annual 
energy consumption for a standard dishwasher. (77 FR 31444, May 25, 
2012) (May 2012 SNOPR). (DOE notes that the percentage cited in the May 
2012 SNOPR references the 355 kWh per year standard applicable to 
standard dishwashers until May 30, 2013. The statement should therefore 
read ``less'' than 5 percent because 17 kWh/year represents 4.8 percent 
of 355 kWh/year.) \2\ AHAM stated that this conclusion was unchanged 
when DOE proposed a less burdensome method to measure the energy use in 
fan-only mode in response to public comment (77 FR 49064, Aug. 15, 
2012) (August 2012 SNOPR). AHAM also stated that it collected data 
showing that measuring fan-only mode energy use would add a shipment-
weighted average of 0.29 kWh per year in measured energy. According to 
AHAM, this increase in energy use could add up to 2 percent of the 2013 
standard in measured energy for some models.
---------------------------------------------------------------------------

    \2\ In addition, DOE emphasizes, as discussed in Section III of 
this notice, that adjustments, if any, required under 42 U.S.C. 
6293(e)(2) would be made based on the average change in measured 
energy use. According to AHAM's data, this shipment adjusted average 
would be only a 0.29 kWh per year change, or 0.1 percent of the 
energy use for standard dishwashers allowed under the standards 
established in the direct final rule.
---------------------------------------------------------------------------

    AHAM asserted that notwithstanding DOE's arguments that the energy 
use in

[[Page 21216]]

fan-only mode is de minimis--the fan-only mode energy use is estimated 
to be less than 5 percent of the total energy use of standard 
dishwashers, and 65 percent of dishwashers currently on the market meet 
the amended energy conservation standards adopted in the direct final 
rule--DOE is still required to ensure that the stringency of the 
amended standards adopted in the direct final rule remains unchanged. 
AHAM argued that DOE has not explained what it considers to be de 
minimis, and that Congress did not provide a de minimis exception to 
the standards amendment requirements in 42 U.S.C. 6293. AHAM also 
pointed out that the stakeholders to the consensus agreement, upon 
which the standards in the direct final rule were based, stated that if 
DOE amended the test procedure prior to the compliance date of the 
agreed-to standards, the stakeholders would recommend that DOE 
translate the standards to equivalent levels specified under revised 
test procedures, as specified in 42 U.S.C. 6293(e).

B. Standby and Off Mode

    In support of AHAM's contention that the standby and off mode test 
procedure revisions require an adjustment of the standard, AHAM noted 
DOE's conclusion that while DOE did not expect the estimated annual 
energy use (EAEU) or estimated annual energy cost to be significantly 
affected by the proposed amendments to measure standby and off mode 
energy use, integrating such energy use into the overall efficiency 
metric would produce a measureable difference in EAEU (Public Meeting 
Transcript, Dec. 17, 2010).\3\ AHAM also disagreed with DOE's 
conclusion, reiterated in the September 2011 SNOPR, that the proposed 
standby and off mode amendments would not measurably alter the existing 
energy efficiency and energy use metrics for dishwashers (76 FR 58346, 
58355, Sept. 20, 2011). AHAM stated that because the proposed 
amendments change what energy will be measured (i.e., the end of cycle 
energy, including cycle finished mode, would be measured under the 
proposed revisions), DOE should amend the standards to account for this 
change. AHAM also stated that it collected data showing that measuring 
standby and off mode energy use would add a shipment-weighted average 
of 1.10 kWh per year. In addition, because the 1.10 kWh is an average, 
AHAM stated that some manufacturers will be more significantly 
affected.
---------------------------------------------------------------------------

    \3\ DOE held the public meeting to discuss its notice of 
proposed rulemaking to amend the test procedure for dishwashers, 
dehumidifiers and conventional cooking products (75 FR 75920, Dec. 
2, 2010) (December 2010 NOPR).
---------------------------------------------------------------------------

    As with fan-only mode, AHAM pointed out that the stakeholders to 
the consensus agreement, upon which the standards in the direct final 
rule were based, agreed that if the test procedure were amended, the 
stakeholders would recommend that DOE translate the standards to 
equivalent levels specified under revised test procedures, as specified 
in 42 U.S.C. 6293(e). In addition, AHAM asserted that DOE took this 
approach in establishing revised standards for room air-conditioners 
and clothes dryers in its direct final rule establishing amended energy 
conservation standards (76 FR 22454, Apr. 21, 2011; 76 FR 52854, Aug. 
24, 2011).

II. Discussion of Comments Received

    DOE published AHAM's petition for comment on December 31, 2012 (77 
FR 76952). DOE received five comments on the petition. These comments 
and DOE's responses are set forth in the paragraphs that follow.
    BSH Home Appliances Corporation (BSH) \4\ and General Electric 
Appliances (GE) \5\ supported AHAM's petition and stated that DOE 
should determine the impacts on measured energy use resulting from the 
test procedure and adjust the applicable standards levels accordingly. 
BSH commented further that the impacts of the new standby power 
measurement ranged from 0-21 kWh/year for the BSH models tested, which 
BSH stated was not ``de minimis''.\6\ BSH also stated that DOE should 
recognize: (1) Any reduction in energy consumption will have an 
influence on cleaning performance; (2) Changes in product ratings are 
expensive, difficult to manage on sales floors and cause confusion to 
the consumer and to rebate programs; (3) The changes could cause some 
units to fall off of the ``Energy Star'' list, which may result in 
discontinuing production of the impacted models and increased cost.

2013.
    \5\ DOE Docket No. EERE-2012-BT-PET-0053, Comment 7, January 31, 
2013.
    \6\ BSH also commented regarding the test procedure provisions 
for measuring the energy used during water softener regeneration. As 
stated in DOE's final test procedure rule, manufacturers have been 
required to measure this energy (and water) use to demonstrate 
compliance with existing standards. 77 FR 65942, 65946-47 (Oct. 31, 
2012). As a result, such energy and water use would not be 
considered in determining whether standards adjustments may be 
required under 42 U.S.C. 6293(e).
---------------------------------------------------------------------------

    Further analysis of DOE's de minimis conclusion in light of the 
data submitted by AHAM and BSH, as well as DOE's analysis concerning 
the appropriateness of adjusting the energy conservation standard 
levels established in the direct final rule is set forth in Section III 
of this notice. In the paragraphs that follow, DOE provides information 
developed during the test procedure rulemaking in support of the de 
minimis conclusion and responds to the related comments offered by BSH.
    For standby and off mode energy use, DOE proposed to measure such 
energy use in the December 2010 proposed test procedure amendments 
using IEC Standard 62301 ``Household electrical appliances--Measurement 
of standby power,'' First Edition 2005-06 (IEC 62301). 75 FR 75290 
(Dec. 2, 2010). In the September 2011 SNOPR, DOE proposed to measure 
such energy use using the Second Edition of IEC 62301, as recommended 
by commenters. 76 FR 58346 (Sept. 20, 2011). DOE analyzed the change in 
measured energy use, if any, that would occur as a result of these 
proposed changes and concluded that these amendments would not 
measurably alter the energy use of dishwashers. 75 FR 75290, 75316-17; 
76 FR 58346, 58355 (Dec. 2, 2010).
    For fan-only mode energy use, DOE proposed a method to measure such 
energy use in the May 2012 SNOPR (71 FR 31444, 31447) and proposed an 
alternative method to measure such energy use in the August 2012 SNOPR 
based on comments received from interested parties, including 
manufacturers (77 FR 49064, 49067). DOE determined that the energy use 
measured in fan-only mode would represent less than 5 percent of the 
total energy use of standard dishwashers. Given that 65 percent of all 
standard dishwashers currently on the market meet or exceed the minimum 
energy conservation standards established in the direct final rule, 
inclusion of this small amount of energy use would have virtually no 
impact on compliance with the revised standard. As a result, DOE 
determined that the energy use in fan-only mode is de minimis and 
insufficient to alter in a material manner the measured energy use of 
dishwashers. 77 FR 65942, 65947 (Oct. 31, 2012).
    In response to BSH's other comments, DOE considered impacts to 
consumer utility in adopting the standards established in the direct 
final rule and concluded that the standards adopted in that rule would 
not impact product utility. 77 FR 31918, 31956-57 (May 30, 2012). In 
addition, DOE takes no position on the business or marketing decisions 
made by manufacturers in response to amendments to applicable

[[Page 21217]]

DOE regulations, including whether to discontinue models that no longer 
meet ENERGY STAR standards. DOE further notes that changes to the 
ENERGY STAR compliance of certain models can occur with any amendment 
of DOE's energy conservation standards and are not specific to DOE's 
amendments to the standards for dishwashers in the direct final rule.
    The California IOUs (Pacific Gas and Electric Company, Southern 
California Gas Company, San Diego Gas and Electric, and Southern 
California Edison) and a number of energy efficiency advocates and 
consumer groups (Appliance Standards Awareness Project, American 
Council for an Energy Efficient Economy, Alliance to Save Energy, 
Consumer Federation of America, Natural Resources Defense Council, 
Northwest Energy Efficiency Alliance, Northwest Power and Conservation 
Council, and Earthjustice, hereinafter referred to as the ``Joint 
Commenters'') opposed staying the effective date of the direct final 
rule. These commenters also stated that if manufacturers provide data 
documenting non-compliance with the standard as a result of the test 
procedure changes, DOE could stay those portions of the test procedure 
specified in AHAM's petition.
    The Joint Commenters also stated that AHAM has not shown that DOE 
was incorrect in concluding that any impact on measured energy 
consumption would be de minimis. Based on AHAM's data, the Joint 
Commenters concluded that the change in measured energy use as a result 
of the disputed test procedure provisions would only be one-half of one 
percent of the new standard levels, rather than the two percent noted 
by AHAM. In addition, because any adjustment to the standard pursuant 
to 42 U.S.C. 6293(e) would be made based on averages, the Joint 
Commenters concluded that any products that fall out of compliance with 
the new standards due to their significantly above-average 
fan[hyphen]only and standby and off mode energy use would still be 
non[hyphen]compliant even if DOE adjusted the standards. The Joint 
Commenters also offered that EPCA, as amended, does not authorize DOE 
to amend the standards in response to AHAM's petition because the test 
procedure rulemaking had concluded.
    As explained in Section III of this notice, DOE declines to grant 
AHAM's request to stay the effective date of the standards established 
in the direct final rule until DOE: (1) Revises the standards in the 
final standards rule to account for the impact on measured energy 
resulting from test procedure amendments to measure fan-only mode and 
standby and off mode energy use; or (2) delays requirements regarding 
measurement of fan-only mode and standby and off mode energy use until 
promulgation of a revised standard for dishwashers. As part of this 
determination, DOE maintains its conclusion that the energy use in fan-
only and standby and off mode is de minimis. DOE welcomes data on 
dishwasher performance under the amended test procedure at any time. 
Given DOE's conclusions, DOE does not reach the Joint Commenter's 
argument concerning compliance with 42 U.S.C. 6293(e) once a test 
procedure rulemaking has been completed.
    DOE also received a comment from a private citizen asserting the 
need for energy efficient appliances as soon as possible at a 
reasonable cost. The commenter recommended that the Federal government 
provide incentives to the American manufacturers to produce these 
products. This comment is outside the scope of DOE's response to the 
AHAM petition.

III. Legal Analysis and Decision

    EPCA requires DOE to determine to what extent, if any, proposed 
test procedure amendments would alter the measured energy efficiency, 
energy use, or water use 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 will alter the measured energy efficiency, 
energy use, or water use of a covered product, DOE must amend the 
applicable energy conservation standard. The amended standard is 
calculated as the average of the energy efficiency, energy use, or 
water use determined by testing a representative sample of products 
that minimally comply with the existing standard using the amended test 
procedure. 42 U.S.C. 6293(e)(2).\7\ DOE's authority to amend energy 
conservation standards does not affect DOE's obligation to issue final 
rules as described in 42 U.S.C. 6295. 42 U.S.C. 6293(e)(4).
---------------------------------------------------------------------------

    \7\ EPCA also states that models of covered products in use 
before the date on which the amended standard becomes effective (or 
revisions of such models that have the same energy efficiency, 
energy use, or water use characteristics) that comply with the 
energy standard applicable to those products are deemed to comply 
with the amended standard. 42 U.S.C. 6293(e)(3). Because DOE 
determined that amended standards were not warranted, this provision 
does not apply in this case.
---------------------------------------------------------------------------

    In applying these provisions to the energy conservation standards 
adopted in the direct final rule for dishwashers, DOE determined that 
no adjustment to the standard levels was warranted because the changes 
in measured energy use resulting from the test procedure amendments for 
the measurement of fan-only mode and standby and off mode energy use 
were de minimis and, therefore, the extent of change in measured energy 
use, if any, would not materially alter the standard levels.
    AHAM argues in its petition that DOE must grant the requested 
relief, either adjusting the standard levels established in the direct 
final rule or delaying compliance with the test procedure provisions 
for measuring energy use in fan-only mode and standby and off mode, 
because Congress did not provide a de minimis exception to the 
requirements of 42 U.S.C. 6293(e)(2). In response, DOE emphasizes that 
42 U.S.C. 6293(e)(1) requires DOE to determine ``to what extent, if 
any'' the proposed test procedure would alter the measured energy 
efficiency or energy or water use of a covered product. This provision, 
requiring DOE to determine ``the extent'', if any, of any alteration in 
measured energy use, means the provision must apply only beyond some 
minimum amount. That is, there would be no reason for the Secretary to 
determine ``the extent'' of the change if any alteration in measured 
energy use would trigger the requirements of 42 U.S.C. 6293(e)(2). 
Thus, DOE has the discretion to determine that the amount of change in 
measured energy use is so insignificant that the standard would not be 
materially altered. As such, when DOE determines the change in measured 
energy use is de minimis, amendment of the standard under 42 U.S.C. 
6293(e)(2) would serve no purpose and would therefore not be required.
    As noted in Section II of this notice, DOE analyzed the change in 
measured energy use, if any, that would occur as a result of the 
proposed changes to the measurement of standby mode and off mode energy 
use, and fan-only mode energy use. As discussed in the paragraphs that 
follow, DOE determined that the data submitted by manufacturer 
commenters does not change the conclusion that measurement of the 
energy use in fan-only mode and standby and off mode is insufficient to 
materially alter the measured energy use of dishwashers and therefore 
does not require an adjustment of the energy conservation standards 
established in the direct final rule.
    DOE estimated fan-only mode energy use at 0.4-17 kWh per year, 
which even at the high end of the range is less than 5 percent of the 
energy use of standard dishwashers. DOE emphasizes, and agrees with the 
point made by the Joint Commenters, that a standards

[[Page 21218]]

adjustment required by 42 U.S.C. 6293(e)(2) would be based on the 
average change in measured efficiency, which would be less than the 
high end of the range estimated by DOE. In fact, based on the data AHAM 
collected, fan-only mode energy use would represent an estimated 0.29 
kWh per year for a shipment-weighted average, which is less than the 
lower end of the range calculated by DOE and represents roughly only 
0.1 percent of the energy use for standard dishwashers allowed under 
the standards established in the direct final rule. DOE assumes that 
the 2 percent increase in energy use cited by AHAM in its petition 
refers to units that used more than the shipment-weighted average 
energy use in fan-only mode. As noted, if any adjustment to an energy 
conservation standard were determined necessary under 42 U.S.C. 
6293(e)(2), the adjustment would be based on the average change in 
measured efficiency, or the 0.1 percent figure. The data submitted by 
AHAM are therefore insufficient to change DOE's conclusion that the 
energy use in fan-only mode is de minimis.
    DOE estimates standby and off mode energy use at 2 percent of total 
energy use of a standard dishwasher. As noted in the test procedure 
rulemaking and in Section II of this notice, DOE further estimated that 
the test procedure amendments made for appendix C1 would not materially 
alter that measured energy use. AHAM collected data showing that the 
updated test procedure for measuring standby and off mode energy use in 
Appendix C1 would add a shipment-weighted average of 1.10 kWh per year. 
BSH submitted data indicating that standby and off mode energy use 
could add up to 21 kWh per year for the BSH models tested. AHAM's 
figure of 1.10 kWh/year is only 0.4 percent of the May 2013 standard 
level for standard dishwashers. DOE notes that the BSH estimate of an 
additional 21 kWh per year of standby and off mode energy use would 
represent an increase in low-power mode consumption of 2 to 3 Watts 
compared to the standby power measured according to Appendix C, which 
is at least three times the maximum inactive or off mode power 
consumption that DOE measured in its sample of 14 dishwashers tested 
for the December 2010 proposed test procedure amendments. DOE also 
notes that its statement about a measurable difference in EAEU at the 
public meeting, noted in Section II of this notice, was meant to convey 
that integration of the standby and off mode energy use into the 
overall efficiency metric pursuant to 42 U.S.C. 6295(gg)(3) would still 
allow for calculation of this energy use, even though the energy use 
measurement was very small. After considering the data submitted by 
commenters, DOE maintains its conclusion that the amendments to measure 
standby and off mode energy use would not measurably alter the energy 
use of dishwashers.
    AHAM also argues in its petition that DOE must adjust the standard 
levels established in the direct final rule or delay compliance with 
the test procedure provisions for measuring energy use in fan-only mode 
and standby and off mode because it has not provided a definition of de 
minimis. DOE does not believe that it is necessary or appropriate to, 
for example, specify an amount or percentage of energy use that would 
be de minimis. Such a concept necessarily depends on factors such as 
the product at issue, the total amount of energy used by the product, 
and the test procedure change at issue.
    DOE has determined in at least one instance that adjustment of the 
standard levels based on test procedure amendments was warranted. As 
AHAM noted, in the direct final rule establishing energy conservation 
standards for clothes dryers and room air conditioners, DOE adjusted 
the standard for clothes dryers based on its estimate of the increase 
in average energy factor that would result from use of the amended test 
procedure, which ranged from 10.3-22.5 percent (77 FR 22454, 22477, 
Apr. 21, 2011). This range is significantly larger than the percentage 
increase DOE estimated for the dishwasher rule and the average 
percentage increase that AHAM estimated--0.29 kWh/year for fan-only 
mode and 1.10 kWh/year for standby and off mode, which represent in 
total approximately 0.45 percent of the May 2013 standards for 
dishwashers.
    Regarding DOE's statement that 65 percent of standard dishwashers 
on the market would meet the standards established in the direct final 
rule, DOE intended to convey that the standard adopted in the direct 
final rule, which represented the maximum improvement in energy 
efficiency that was technologically feasible and economically 
justified, was not so stringent that only a very small percentage of 
dishwashers would comply. In such a case, DOE might consider whether a 
smaller change in measured energy use could trigger the requirements of 
42 U.S.C. 6293(e)(2).
    Even if DOE had determined that the change in measured energy use 
as a result of test procedure provisions for the measurement of standby 
and off mode energy use were not de minimis, DOE could not adjust the 
standard to account for the increase in measured energy use, which 
would result in lowering the current standard by a corresponding 
amount. Such an adjustment would be prohibited by EPCA's anti-
backsliding provision, set forth in 42 U.S.C. 6295(o)(1). DOE's 
authority to amend energy conservation standards in 42 U.S.C. 6293(e) 
specifically does not affect DOE's obligation to issue any final rules 
as described in 42 U.S.C. 6295, including adherence to the anti-
backsliding provision in 6295(o)(1). 42 U.S.C. 6293(e)(4).\8\
---------------------------------------------------------------------------

    \8\ DOE notes that if a test procedure amendment would account 
for less energy use, thus raising the standard by some amount that 
DOE determined was not de minimis, 42 U.S.C. 6293(e)(3) would 
``grandfather'' existing models in use on or before the date on 
which the amended energy conversation standard becomes effective (or 
revisions of such models that have the same energy efficiency, 
energy use or water use characteristics) that complied with the 
standard prior to the test procedure amendments that raised the 
standard.
---------------------------------------------------------------------------

    As a result of the above analysis, and in consideration of AHAM's 
petition and the comments received thereon, DOE declines to grant the 
petition.
