SUPPLEMENTARY INFORMATION: The
Administrative Procedure Act (APA), 5
U.S.C. 551 et seq., provides among other
things, that ‘‘[each] agency shall give an
interested person the right to petition
for the issuance, amendment, or repeal
of a rule.’’ (5 U.S.C. 553(e)). Pursuant to
this provision of the APA, the
Association of Home Appliance
Manufacturers and the Appliance
Standards Awareness Project, on behalf
of a number of named parties,
petitioned DOE to amend the test
procedure for residential clothes dryers
to include provisions related to
automatic termination controls, as set
forth below. In promulgating this
petition for public comment, the DOE is
seeking views on whether it should
grant the petition and consider the
proposal contained in the petition. By
seeking comment on whether to grant
this petition, the DOE takes no position
at this time regarding the merits of the
suggested amendment.
The proposed amendment sought in
the petition would institute a procedure
that addresses the effectiveness of
automatic termination controls such as
moisture and temperature sensor
controls. The petitioners request that
DOE test the full cycle of clothes dryers,
including cool-down. The petitioners
also request that the DOE modify the
ending remaining moisture content
(RMC) to require that the RMC be no
more than 2 percent when testing units
equipped with automatic termination
controls using the DOE test load. This
petition also requests that the DOE
revise the relevant energy conservation
standards under section 323 of the
Energy Policy and Conservation Act to

reflect the requested test procedure. The
DOE seeks public comment on whether
it should grant the petition.
DOE notes that it issued a Request for
Information (RFI) to further investigate
the effects of automatic cycle
termination on the energy efficiency of
clothes washers. (76 FR 50145, Aug. 12,
2011). The petition also served as a
response to DOE’s RFI.

I. Introduction and Overview
As part of the agreement between the
Joint Commenters on federal minimum
energy conservation standards for five
products, including residential clothes
dryers, and related test procedures,
ENERGY STAR, and financial incentive
provisions, the Joint Commenters agreed
that the Department of Energy (DOE)
should amend the clothes dryer test
procedure to address the effectiveness of
automatic termination controls such as

moisture and temperature sensor
controls. In its final test procedure,
however, DOE declined to adopt
proposed amendments to address
automatic termination controls. The
Joint Commenters estimate that energy
savings of approximately 1.1 quads over
30 years can be achieved through a test
procedure revision that accounts for
such controls, and thus petition DOE to
amend the clothes dryer test procedure
to account for the effectiveness of
automatic termination controls.2 This
petition also serves as joint comments in
response to DOE’s Request for
Information on Test Procedures for
Residential Clothes Dryers, Docket No.

III. Background
DOE proposed to amend DOE’s test
procedure for clothes dryers to
incorporate the individual test
procedures for timer dryers and
automatic termination control dryers in
AS/NSZ Standard 2442 with a few
modifications. DOE sought comment on
the adequacy of AS/NSZ Standard 2442,
along with proposed definitions and
clarifications, to measure energy
consumption for timer and automatic
termination control clothes dryers to
account for over-drying energy
consumption. The Joint Commenters
supported DOE’s proposal to account for
the effectiveness of automatic
termination controls because it would
have provided an incentive to
E:\FR\FM\11OCP1.SGM

62646
Federal Register / Vol. 76, No. 196 / Tuesday, October 11, 2011 / Proposed Rules
srobinson on DSK4SPTVN1PROD with PROPOSALS
manufacturers to design products that
avoid over-drying. Although the Joint
Stakeholders generally promote
harmonization with international
standards, the Joint Stakeholders did
not agree that AS/NSZ Standard 2442
provided the best methods and
procedures to account for the amount of
over- drying associated with automatic
termination control dryers beyond a
specified RMC.
Instead, the Joint Stakeholders
proposed that the procedure should be
to test the full cycle, including cooldown. This procedure is more
representative of consumer usage
because it includes all of the energy use
in a cycle. It is also reproducible and
repeatable because it does not require
any ‘‘guesswork’’ as to when the cooldown will begin. On the other hand,
DOE’s original proposal to stop the
dryer when the heater switches off for
the final time at the end of the drying
cycle, i.e., immediately before the cooldown period begins, entails some
guesswork that introduces variability
into the test. The procedure the Joint
Stakeholders’ proposed is also less
burdensome because it does not require
the manufacturers to conduct multiple
tests in order to determine the point
immediately before cool-down for each
model. Thus, the Joint Stakeholders
argued that their proposal improved
upon DOE’s proposal in addressing
over-drying by including cool-down.
Furthermore, for dryers that have both
an automatic termination control cycle
and a timer cycle, the Joint Stakeholders
argued that only the automatic
termination cycle should be tested.
Finally, the Joint Stakeholders argued
that if DOE adopted the Joint
Stakeholders’ proposed test procedure,
i.e., to test the full cycle including cooldown, it must also revise the relevant
energy conservation standards to reflect
the new test procedure, ensuring that for
dryers with effective automatic
termination controls, there is no change
in the stringency of the standards, per
section 323 of the Energy Policy and
Conservation Act. Specifically, the Joint
Stakeholders argued, the procedures in
section 323(e)(2) should be used, with
the clarification that for the purposes of
establishing a representative sample of
products, DOE should choose a sample
of minimally compliant dryers which
VerDate Mar<15>2010
17:42 Oct 07, 2011
Jkt 223001
automatically terminate the drying cycle
at no less than four percent RMC.
In the final test procedure, DOE
declined to adopt the amendments it
had proposed with regard to automatic
termination controls (with or without
the modifications proposed by the Joint
Stakeholders). DOE determined, based
on test results, that
given the load specified in the current
DOE test procedure, the proposed
automatic cycle termination control
procedures may not adequately measure
clothes dryer performance * * *. DOE
believes that, although automatic
termination control dryers may be
measured as having a lower efficiency
than a comparable dryer with only time
termination control if tested according
to the proposed test procedure,
automatic termination control dryers
may in fact be drying the clothing to
approximately 5-percent RMC in real
world use. DOE believes that automatic
termination control dryers reduce
energy consumption (by reducing overdrying) compared to timer dryers based
on analysis of the AHAM field use
survey and analysis of the field test data
conducted by NIST. (76 Fed. Reg. 972,
1000 (Jan. 6, 2011)).
DOE also stated that if data were
available to develop a test procedure
that accurately measures the energy
consumption of clothes dryers equipped
with automatic termination controls, it
could consider revised amendments to
the test procedure. (Id.).
IV. Proposal
The Joint Stakeholders now present
data to assist in the development of a
test procedure that accurately measures
the energy consumption of clothes
dryers equipped with automatic
termination controls, and request that
DOE amend the clothes dryer test
procedure to include procedures to
account for automatic termination
controls.
DOE was concerned that the proposed
test procedure may not properly
measure the effectiveness of automatic
termination controls, particularly in
light of data that suggested that
automatic termination control dryers
may in fact be drying clothing to
approximately five percent remaining
moisture content (RMC) in the real
world. The Joint Stakeholders
PO 00000
Frm 00003
Fmt 4702
Sfmt 4702
determined that the best way to address
DOE’s concern was to account for the
fact that the test procedure has inherent
differences from consumer use that are
necessary for repeatability and
reproducibility. The most significant
difference between the test procedure
and consumer use is the DOE test cloth,
which does not represent a variety of
cloth used by consumers. The DOE test
cloth is uniform, whereas a consumer
load contains items of varying weights,
composition, and size. Thus, the DOE
test cloth likely dries faster and more
uniformly than an actual consumer
load.
AHAM members conducted testing on
clothes dryers with automatic
termination controls that are currently
on the market—the clothes dryers tested
represent about 60 percent of
shipments. Because there are few
consumer complaints that clothes dryers
equipped with automatic termination
controls do not dry clothes, the testing
assumed that the current market ending
RMC is appropriate. The testing was
conducted per the following conditions
which closely approximated DOE’s
proposed test procedure, except that the
entire cycle was tested, including cooldown:
• Test procedure: Existing DOE test
procedure, not including most recent
amendments.
• Starting RMC: 70% ± 3.5%.
• Test load: DOE load.
• Test runs: Three tests on each
machine, average ending RMC reported
to AHAM.
• Program: A ‘‘normal’’ program
(cycle) shall be selected. Where the
dryness level can be chosen
independently of the program, the
‘‘normal’’ level shall be selected. Where
the drying temperature (setting) can be
chosen independently of the program, it
shall be set to the maximum.
• Tests were run until the automatic
termination controls stopped the clothes
dryer (i.e., cool-down was included).
• Data was de-identified and
aggregated by AHAM.
The test results, shown in Table 1,
demonstrated that an ending RMC of
two percent using the DOE test cloth
best approximates the maximum,
consumer accepted, ending RMC.
E:\FR\FM\11OCP1.SGM
11OCP1
Based on this data, the Joint
Stakeholders request that DOE adopt the
test procedure amendments it
previously proposed except that it
should modify the proposal to state that
testing will include the full cycle,
including cool-down. As the Joint
Stakeholders previously commented,
and is discussed in more detail in
Section III above, testing the entire cycle
including cool-down is more
representative of actual consumer use
and is less of a test burden for
manufacturers than DOE’s original
proposal to stop the dryer when the
heater switches off for the final time at
the end of the drying cycle. In addition,
DOE should modify its original proposal
to state that ending RMC when testing
units equipped with automatic
termination controls shall be no more
than two percent when testing with the
DOE test load. That maximum
percentage, according to the data above,
is representative of clothes dryers
currently on the market. Consistent with
DOE’s proposal, but substituting two
percent ending RMC for five percent
ending RMC, any test cycle in which the
final RMC is two percent or less should
be considered valid. If the final RMC is
greater than two percent, the test would
be invalid and a new run would be
conducted using the highest dryness
level setting.
V. Revision of Standards
If DOE adopts the Joint Stakeholders’
proposals in this petition, which would
test the full cycle, including cool-down,
VerDate Mar<15>2010
17:42 Oct 07, 2011
Jkt 223001
and result in a change in measured
energy, it must also revise the relevant
energy conservation standards to reflect
the new test procedure, ensuring that for
dryers with effective automatic
termination controls, there is no change
in the stringency of the standards, per
section 323 of the Energy Policy and
Conservation Act. Specifically, the
procedures in section 323(e)(2) should
be used, with the clarification that for
the purposes of establishing a
representative sample of products, DOE
should choose a sample of minimally
compliant dryers which automatically
terminate the drying cycle at 1.5 to 2
percent RMC. By selecting products that
terminate at 1.5 to 2 percent, DOE will
assure that the revised standard is based
upon dryers which do not over-dry.
This approach will also assure that the
tested sample yields valid results under
both the current and proposed revised
test procedure.
We note that in the test procedures
SNOPR, DOE stated that for the
purposes of determining the effects of
an amended test procedure on the
measured efficiency of clothes dryers,
the measurement of only clothes dryers
that terminate the drying cycle at no less
than a particular RMC would not
constitute a representative sample.3 If
DOE continues to hold this view, the
test procedure proposal in this petition
should still be adopted. In that case,
DOE could revise the standards without
limiting the representative sample of
3 76
PO 00000
Fed. Reg. 1026 (January 6, 2011).
Frm 00004
Fmt 4702

62647
dryers based on automatic termination
performance. As described in the next
section, that alternate approach would
reduce, but not eliminate, the benefits
from this test procedure change and,
therefore, we urge DOE to reconsider its
position.
VI. Energy Savings Potential
If DOE adopts the Joint Stakeholders’
proposals in this petition,
manufacturers will have an incentive to
refine their automatic termination
feature to terminate very close to two
percent maximum ending RMC using
the DOE test load. As Figure 1
demonstrates, a large percentage of
clothes dryers currently on the market
dry to levels below the proposed two
percent ending RMC. As manufacturers
make these refinements, two things will
happen—the measured energy
efficiency of the dryer will improve and
the ‘‘real world’’ energy consumption of
the dryer will be reduced. This is
exactly what should happen as the
result of such a change in the test
procedure towards conditions that more
closely replicate consumer use.
To estimate energy savings from the
proposals for a test procedure
amendment and a revision to the
standards presented in this petition, we
assume that the AHAM test load is
representative of consumer loads. The
DOE test data presented in the test
procedures SNOPR showed that the
maximum ending RMC using the
E:\FR\FM\11OCP1.SGM

srobinson on DSK4SPTVN1PROD with PROPOSALS
Federal Register / Vol. 76, No. 196 / Tuesday, October 11, 2011 / Proposed Rules
62648
Federal Register / Vol. 76, No. 196 / Tuesday, October 11, 2011 / Proposed Rules
AHAM test load was five percent.4 As
noted above, the AHAM test data
suggest that an ending RMC of two
percent using the DOE test load best
approximates the maximum, consumer
accepted, ending RMC. We assume that
an ending RMC of two percent with the
DOE test load translates to an ending
RMC of five percent using the AHAM
test load, and we also assume that the
average ending RMC using the DOE test
load translates to the average ending
RMC using the AHAM test load. The
SNOPR data showed that the average
over-drying energy consumption (i.e.
energy consumed after the dryer reaches
an RMC of five percent) using the
AHAM test load based on the four
models tested with a ‘‘normal cycle’’
and ‘‘normal dryness’’ was 0.18 kWh
per cycle.5 Based on this data, we
estimate that a test procedure change
and a revision to the standards as
proposed in this petition would result
in average per-unit energy savings of
0.18 kWh per cycle, or 51 kWh per year,
and cumulative national energy savings
of approximately 1.1 quads over 30
years.6
If DOE determines that it cannot limit
the representative sample to dryers that
terminate within a 1.5 to 2 percent RMC
range for purposes of revising the
standard levels, national energy savings
would be reduced, but significant
savings would still be achieved. Dryers
with automatic termination controls that
perform worse than average would need
to improve such that they consume no
more energy than an average dryer. DOE
noted in the test procedures SNOPR that
there is an exponential trend in the plot
of energy consumption as a function of
RMC below an RMC of about five
percent likely because it becomes more
difficult to remove the lesser amounts of
moisture remaining in the load.7 This
exponential trend suggests that dryers
that currently terminate at very low
RMCs consume significant amounts of
over-drying energy and that requiring
dryers with poor automatic termination
controls to improve such that they
perform as well as an average dryer
represents a significant savings
opportunity.
We recognize that there are significant
uncertainties in estimating energy
savings from the proposed test
procedure in this petition. However,
energy savings will certainly be
achieved by encouraging use of better
automatic termination controls to
reduce over-drying energy consumption.
In addition, an amended test procedure
as proposed in this petition would
capture all the energy use of a dryer
cycle, which would better represent
real-world dryer energy consumption
and allow manufacturers more options
for improving rated dryer efficiency.
VII. Timing
We recommend that test procedure
and standards revisions adopted in
response to this petition take effect on
January 1, 2015. Our goal is to have a
single round of standards and test
procedure changes take effect. Thus,
these test procedure and related
standards amendments would replace
the final test procedure issued in
January 2011 and the dryer standards
contained in the Direct Final Rule
issued in April 2011.
In order to give manufacturers
adequate time to prepare for a revised
test procedure and standards, we urge
DOE to complete and finalize the test
procedure and standards revisions as
soon as possible, but no later than
December 31, 2011. We suggest that
DOE propose the modifications to the
standards required by Section 323(e) in
parallel to modifications to the test
procedure. Parallel revisions to the test
procedure and standards will provide
stakeholders the clearest understanding
of the impacts of the changes and enable
the fastest resolution of the issues raised
in this petition. The timing suggested in
this petition is contingent on DOE
providing adequate lead-in time for
manufacturers to develop products that
will comply with the revised standard
per the revised test procedure that more
effectively accounts for automatic
termination controls. In order to provide
adequate lead-in time, it is necessary
that the test procedures and standards
are completed and final no later than
December 31, 2011.
VIII. Conclusion
Because data is now available to
support a test procedure that accurately
measures the effectiveness of automatic
termination controls, the Joint
Commenters request that DOE amend
the clothes dryer test procedure to
account for the effectiveness of
automatic termination controls as
discussed in Section IV above. Such
amendments to account for the
effectiveness of automatic termination
controls will help to prevent overdrying and will, thus, result in energy
savings. If DOE adopts procedures to
amend the test procedure to measure the
effectiveness of automatic termination
controls, it must also revise the relevant
energy conservation standards to reflect
the new test procedure, ensuring that for
dryers with effective automatic
termination controls, there is no change
in the stringency of the standards, per
section 323 of the Energy Policy and
Conservation Act.

ACTION: Supplemental notice of
proposed rulemaking (NPRM);
reopening of comment period.
AGENCY:
We are revising an earlier
proposed airworthiness directive (AD)
for the products listed above. That
second supplemental NPRM proposed a
one-time inspection to determine the
part numbers of the aero/fire seals of the
blocker doors on the thrust reverser
torque boxes on the engines, and
replacing affected aero/fire seals with
new, improved aero/fire seals. That
second supplemental NPRM was
prompted by a report that the top 3
inches of the aero/fire seals of the
blocker doors on the thrust reverser
torque boxes are not fireproof. This
action revises the second supplemental
NPRM by prohibiting installation of
certain non-fireproof thrust reverser
seals. We are proposing this third
supplemental NPRM to prevent a fire in
the fan compartment (a fire zone) from
srobinson on DSK4SPTVN1PROD with PROPOSALS

migrating through the seal to a
flammable fluid in the thrust reverser
actuator compartment (a flammable
fluid leakage zone), which could result
in an uncontrolled fire. Since these
actions impose an additional burden
over that proposed in the second
supplemental NPRM, we are reopening
the comment period to allow the public
the chance to comment on these
proposed changes.
DATES: We must receive comments on
this supplemental NPRM by November
25, 2011.

SUPPLEMENTARY INFORMATION: The Administrative Procedure Act (APA), 5
U.S.C. 551 et seq., provides among other things, that ``[each] agency
shall give an interested person the right to petition for the issuance,
amendment, or repeal of a rule.'' (5 U.S.C. 553(e)). Pursuant to this
provision of the APA, the Association of Home Appliance Manufacturers
and the Appliance Standards Awareness Project, on behalf of a number of
named parties, petitioned DOE to amend the test procedure for
residential clothes dryers to include provisions related to automatic
termination controls, as set forth below. In promulgating this petition
for public comment, the DOE is seeking views on whether it should grant
the petition and consider the proposal contained in the petition. By
seeking comment on whether to grant this petition, the DOE takes no
position at this time regarding the merits of the suggested amendment.
The proposed amendment sought in the petition would institute a
procedure that addresses the effectiveness of automatic termination
controls such as moisture and temperature sensor controls. The
petitioners request that DOE test the full cycle of clothes dryers,
including cool-down. The petitioners also request that the DOE modify
the ending remaining moisture content (RMC) to require that the RMC be
no more than 2 percent when testing units equipped with automatic
termination controls using the DOE test load. This petition also
requests that the DOE revise the relevant energy conservation standards
under section 323 of the Energy Policy and Conservation Act to reflect
the requested test procedure. The DOE seeks public comment on whether
it should grant the petition.
DOE notes that it issued a Request for Information (RFI) to further
investigate the effects of automatic cycle termination on the energy
efficiency of clothes washers. (76 FR 50145, Aug. 12, 2011). The
petition also served as a response to DOE's RFI.

I. Introduction and Overview
As part of the agreement between the Joint Commenters on federal
minimum energy conservation standards for five products, including
residential clothes dryers, and related test procedures, ENERGY STAR,
and financial incentive provisions, the Joint Commenters agreed that
the Department of Energy (DOE) should amend the clothes dryer test
procedure to address the effectiveness of automatic termination
controls such as
[[Page 62645]]
moisture and temperature sensor controls. In its final test procedure,
however, DOE declined to adopt proposed amendments to address automatic
termination controls. The Joint Commenters estimate that energy savings
of approximately 1.1 quads over 30 years can be achieved through a test
procedure revision that accounts for such controls, and thus petition
DOE to amend the clothes dryer test procedure to account for the
effectiveness of automatic termination controls.\2\ This petition also
serves as joint comments in response to DOE's Request for Information
on Test Procedures for Residential Clothes Dryers, Docket No. EERE-
2011-BT-TP-0054, RIN 1904-AC63, 76 Fed Reg. 50145 (Aug. 12, 2011).

III. Background
DOE proposed to amend DOE's test procedure for clothes dryers to
incorporate the individual test procedures for timer dryers and
automatic termination control dryers in AS/NSZ Standard 2442 with a few
modifications. DOE sought comment on the adequacy of AS/NSZ Standard
2442, along with proposed definitions and clarifications, to measure
energy consumption for timer and automatic termination control clothes
dryers to account for over-drying energy consumption. The Joint
Commenters supported DOE's proposal to account for the effectiveness of
automatic termination controls because it would have provided an
incentive to
[[Page 62646]]
manufacturers to design products that avoid over-drying. Although the
Joint Stakeholders generally promote harmonization with international
standards, the Joint Stakeholders did not agree that AS/NSZ Standard
2442 provided the best methods and procedures to account for the amount
of over- drying associated with automatic termination control dryers
beyond a specified RMC.
Instead, the Joint Stakeholders proposed that the procedure should
be to test the full cycle, including cool-down. This procedure is more
representative of consumer usage because it includes all of the energy
use in a cycle. It is also reproducible and repeatable because it does
not require any ``guesswork'' as to when the cool-down will begin. On
the other hand, DOE's original proposal to stop the dryer when the
heater switches off for the final time at the end of the drying cycle,
i.e., immediately before the cool-down period begins, entails some
guesswork that introduces variability into the test. The procedure the
Joint Stakeholders' proposed is also less burdensome because it does
not require the manufacturers to conduct multiple tests in order to
determine the point immediately before cool-down for each model. Thus,
the Joint Stakeholders argued that their proposal improved upon DOE's
proposal in addressing over-drying by including cool-down.
Furthermore, for dryers that have both an automatic termination
control cycle and a timer cycle, the Joint Stakeholders argued that
only the automatic termination cycle should be tested.
Finally, the Joint Stakeholders argued that if DOE adopted the
Joint Stakeholders' proposed test procedure, i.e., to test the full
cycle including cool-down, it must also revise the relevant energy
conservation standards to reflect the new test procedure, ensuring that
for dryers with effective automatic termination controls, there is no
change in the stringency of the standards, per section 323 of the
Energy Policy and Conservation Act. Specifically, the Joint
Stakeholders argued, the procedures in section 323(e)(2) should be
used, with the clarification that for the purposes of establishing a
representative sample of products, DOE should choose a sample of
minimally compliant dryers which automatically terminate the drying
cycle at no less than four percent RMC.
In the final test procedure, DOE declined to adopt the amendments
it had proposed with regard to automatic termination controls (with or
without the modifications proposed by the Joint Stakeholders). DOE
determined, based on test results, that
given the load specified in the current DOE test procedure, the
proposed automatic cycle termination control procedures may not
adequately measure clothes dryer performance * * *. DOE believes that,
although automatic termination control dryers may be measured as having
a lower efficiency than a comparable dryer with only time termination
control if tested according to the proposed test procedure, automatic
termination control dryers may in fact be drying the clothing to
approximately 5-percent RMC in real world use. DOE believes that
automatic termination control dryers reduce energy consumption (by
reducing over-drying) compared to timer dryers based on analysis of the
AHAM field use survey and analysis of the field test data conducted by
NIST. (76 Fed. Reg. 972, 1000 (Jan. 6, 2011)).
DOE also stated that if data were available to develop a test
procedure that accurately measures the energy consumption of clothes
dryers equipped with automatic termination controls, it could consider
revised amendments to the test procedure. (Id.).
IV. Proposal
The Joint Stakeholders now present data to assist in the
development of a test procedure that accurately measures the energy
consumption of clothes dryers equipped with automatic termination
controls, and request that DOE amend the clothes dryer test procedure
to include procedures to account for automatic termination controls.
DOE was concerned that the proposed test procedure may not properly
measure the effectiveness of automatic termination controls,
particularly in light of data that suggested that automatic termination
control dryers may in fact be drying clothing to approximately five
percent remaining moisture content (RMC) in the real world. The Joint
Stakeholders determined that the best way to address DOE's concern was
to account for the fact that the test procedure has inherent
differences from consumer use that are necessary for repeatability and
reproducibility. The most significant difference between the test
procedure and consumer use is the DOE test cloth, which does not
represent a variety of cloth used by consumers. The DOE test cloth is
uniform, whereas a consumer load contains items of varying weights,
composition, and size. Thus, the DOE test cloth likely dries faster and
more uniformly than an actual consumer load.
AHAM members conducted testing on clothes dryers with automatic
termination controls that are currently on the market--the clothes
dryers tested represent about 60 percent of shipments. Because there
are few consumer complaints that clothes dryers equipped with automatic
termination controls do not dry clothes, the testing assumed that the
current market ending RMC is appropriate. The testing was conducted per
the following conditions which closely approximated DOE's proposed test
procedure, except that the entire cycle was tested, including cool-
down:
Test procedure: Existing DOE test procedure, not including
most recent amendments.
Starting RMC: 70% 3.5%.
Test load: DOE load.
Test runs: Three tests on each machine, average ending RMC
reported to AHAM.
Program: A ``normal'' program (cycle) shall be selected.
Where the dryness level can be chosen independently of the program, the
``normal'' level shall be selected. Where the drying temperature
(setting) can be chosen independently of the program, it shall be set
to the maximum.
Tests were run until the automatic termination controls
stopped the clothes dryer (i.e., cool-down was included).
Data was de-identified and aggregated by AHAM.
The test results, shown in Table 1, demonstrated that an ending RMC
of two percent using the DOE test cloth best approximates the maximum,
consumer accepted, ending RMC.
[[Page 62647]]
[GRAPHIC] [TIFF OMITTED] TP11OC11.007
Based on this data, the Joint Stakeholders request that DOE adopt
the test procedure amendments it previously proposed except that it
should modify the proposal to state that testing will include the full
cycle, including cool-down. As the Joint Stakeholders previously
commented, and is discussed in more detail in Section III above,
testing the entire cycle including cool-down is more representative of
actual consumer use and is less of a test burden for manufacturers than
DOE's original proposal to stop the dryer when the heater switches off
for the final time at the end of the drying cycle. In addition, DOE
should modify its original proposal to state that ending RMC when
testing units equipped with automatic termination controls shall be no
more than two percent when testing with the DOE test load. That maximum
percentage, according to the data above, is representative of clothes
dryers currently on the market. Consistent with DOE's proposal, but
substituting two percent ending RMC for five percent ending RMC, any
test cycle in which the final RMC is two percent or less should be
considered valid. If the final RMC is greater than two percent, the
test would be invalid and a new run would be conducted using the
highest dryness level setting.
V. Revision of Standards
If DOE adopts the Joint Stakeholders' proposals in this petition,
which would test the full cycle, including cool-down, and result in a
change in measured energy, it must also revise the relevant energy
conservation standards to reflect the new test procedure, ensuring that
for dryers with effective automatic termination controls, there is no
change in the stringency of the standards, per section 323 of the
Energy Policy and Conservation Act. Specifically, the procedures in
section 323(e)(2) should be used, with the clarification that for the
purposes of establishing a representative sample of products, DOE
should choose a sample of minimally compliant dryers which
automatically terminate the drying cycle at 1.5 to 2 percent RMC. By
selecting products that terminate at 1.5 to 2 percent, DOE will assure
that the revised standard is based upon dryers which do not over-dry.
This approach will also assure that the tested sample yields valid
results under both the current and proposed revised test procedure.
We note that in the test procedures SNOPR, DOE stated that for the
purposes of determining the effects of an amended test procedure on the
measured efficiency of clothes dryers, the measurement of only clothes
dryers that terminate the drying cycle at no less than a particular RMC
would not constitute a representative sample.\3\ If DOE continues to
hold this view, the test procedure proposal in this petition should
still be adopted. In that case, DOE could revise the standards without
limiting the representative sample of dryers based on automatic
termination performance. As described in the next section, that
alternate approach would reduce, but not eliminate, the benefits from
this test procedure change and, therefore, we urge DOE to reconsider
its position.

---------------------------------------------------------------------------
VI. Energy Savings Potential
If DOE adopts the Joint Stakeholders' proposals in this petition,
manufacturers will have an incentive to refine their automatic
termination feature to terminate very close to two percent maximum
ending RMC using the DOE test load. As Figure 1 demonstrates, a large
percentage of clothes dryers currently on the market dry to levels
below the proposed two percent ending RMC. As manufacturers make these
refinements, two things will happen--the measured energy efficiency of
the dryer will improve and the ``real world'' energy consumption of the
dryer will be reduced. This is exactly what should happen as the result
of such a change in the test procedure towards conditions that more
closely replicate consumer use.
To estimate energy savings from the proposals for a test procedure
amendment and a revision to the standards presented in this petition,
we assume that the AHAM test load is representative of consumer loads.
The DOE test data presented in the test procedures SNOPR showed that
the maximum ending RMC using the
[[Page 62648]]
AHAM test load was five percent.\4\ As noted above, the AHAM test data
suggest that an ending RMC of two percent using the DOE test load best
approximates the maximum, consumer accepted, ending RMC. We assume that
an ending RMC of two percent with the DOE test load translates to an
ending RMC of five percent using the AHAM test load, and we also assume
that the average ending RMC using the DOE test load translates to the
average ending RMC using the AHAM test load. The SNOPR data showed that
the average over-drying energy consumption (i.e. energy consumed after
the dryer reaches an RMC of five percent) using the AHAM test load
based on the four models tested with a ``normal cycle'' and ``normal
dryness'' was 0.18 kWh per cycle.\5\ Based on this data, we estimate
that a test procedure change and a revision to the standards as
proposed in this petition would result in average per-unit energy
savings of 0.18 kWh per cycle, or 51 kWh per year, and cumulative
national energy savings of approximately 1.1 quads over 30 years.\6\

---------------------------------------------------------------------------
If DOE determines that it cannot limit the representative sample to
dryers that terminate within a 1.5 to 2 percent RMC range for purposes
of revising the standard levels, national energy savings would be
reduced, but significant savings would still be achieved. Dryers with
automatic termination controls that perform worse than average would
need to improve such that they consume no more energy than an average
dryer. DOE noted in the test procedures SNOPR that there is an
exponential trend in the plot of energy consumption as a function of
RMC below an RMC of about five percent likely because it becomes more
difficult to remove the lesser amounts of moisture remaining in the
load.\7\ This exponential trend suggests that dryers that currently
terminate at very low RMCs consume significant amounts of over-drying
energy and that requiring dryers with poor automatic termination
controls to improve such that they perform as well as an average dryer
represents a significant savings opportunity.

---------------------------------------------------------------------------
We recognize that there are significant uncertainties in estimating
energy savings from the proposed test procedure in this petition.
However, energy savings will certainly be achieved by encouraging use
of better automatic termination controls to reduce over-drying energy
consumption. In addition, an amended test procedure as proposed in this
petition would capture all the energy use of a dryer cycle, which would
better represent real-world dryer energy consumption and allow
manufacturers more options for improving rated dryer efficiency.
VII. Timing
We recommend that test procedure and standards revisions adopted in
response to this petition take effect on January 1, 2015. Our goal is
to have a single round of standards and test procedure changes take
effect. Thus, these test procedure and related standards amendments
would replace the final test procedure issued in January 2011 and the
dryer standards contained in the Direct Final Rule issued in April
2011.
In order to give manufacturers adequate time to prepare for a
revised test procedure and standards, we urge DOE to complete and
finalize the test procedure and standards revisions as soon as
possible, but no later than December 31, 2011. We suggest that DOE
propose the modifications to the standards required by Section 323(e)
in parallel to modifications to the test procedure. Parallel revisions
to the test procedure and standards will provide stakeholders the
clearest understanding of the impacts of the changes and enable the
fastest resolution of the issues raised in this petition. The timing
suggested in this petition is contingent on DOE providing adequate
lead-in time for manufacturers to develop products that will comply
with the revised standard per the revised test procedure that more
effectively accounts for automatic termination controls. In order to
provide adequate lead-in time, it is necessary that the test procedures
and standards are completed and final no later than December 31, 2011.
VIII. Conclusion
Because data is now available to support a test procedure that
accurately measures the effectiveness of automatic termination
controls, the Joint Commenters request that DOE amend the clothes dryer
test procedure to account for the effectiveness of automatic
termination controls as discussed in Section IV above. Such amendments
to account for the effectiveness of automatic termination controls will
help to prevent over-drying and will, thus, result in energy savings.
If DOE adopts procedures to amend the test procedure to measure the
effectiveness of automatic termination controls, it must also revise
the relevant energy conservation standards to reflect the new test
procedure, ensuring that for dryers with effective automatic
termination controls, there is no change in the stringency of the
standards, per section 323 of the Energy Policy and Conservation Act.
