I. Background

    The Energy Policy and Conservation Act, as amended (``EPCA''),\1\ 
authorizes DOE to regulate the energy efficiency of a number of 
consumer products and certain industrial equipment. (42 U.S.C. 6291-
6317) Title III, Part B \2\ of EPCA established the Energy Conservation 
Program for Consumer Products Other Than Automobiles. These products 
include consumer conventional cooking products, the subject of this 
rulemaking. (42 U.S.C. 6292(a)(10))
---------------------------------------------------------------------------

    \1\ All references to EPCA in this document refer to the statute 
as amended through the Energy Act of 2020. Public Law 116-260 (Dec. 
27, 2020), which reflect the last statutory amendments that impact 
Parts A and A-1 of EPCA.
    \2\ For editorial reasons, upon codification in the U.S. Code, 
Part B was redesignated Part A.
---------------------------------------------------------------------------

    The currently applicable energy conservation standards for consumer 
conventional cooking products consist of a prescriptive prohibition on 
constant burning pilots for all gas cooking products (i.e., gas cooking 
products both with or without an electrical supply cord) manufactured 
on and after April 9, 2012. These standards are set forth at title 10 
of the Code of Federal Regulations (``CFR'') Sec.  430.32(j)(1) and 
(2).
    Consumer conventional cooking products comprise conventional 
cooking tops and conventional ovens, as defined as 10 CFR 430.2. 
Representations of energy use or energy efficiency of conventional 
cooking tops made on or after February 20, 2023, must be based on 
results generated

[[Page 50811]]

using the test procedure for conventional cooking products at 10 CFR 
part 430, subpart B, appendix I1 (``appendix I1''). There are currently 
no DOE test procedures for conventional ovens.
    On February 1, 2023, DOE published a supplemental notice of 
proposed rulemaking (``February 2023 SNOPR'') proposing to establish 
new and amended standards for consumer conventional cooking products, 
consisting of maximum integrated annual energy consumption (``IAEC'') 
levels, in kilowatt-hours per year (``kWh/year'') for electric cooking 
tops and thousand British thermal units per year (``kBtu/year'') for 
gas cooking tops. 88 FR 6818. Compliance with the new and amended 
standards would be required 3 years after the publication date of final 
rule, should DOE finalize the proposed standards. Id. The technical 
support document (``TSD'') that presented the methodology and results 
of the February 2023 SNOPR analysis is available at: 
www.regulations.gov/document/EERE-2014-BT-STD-0005-0090.
    On February 28, 2023, DOE published a notification of data 
availability (``February 2023 NODA'') providing additional information 
to clarify the February 2023 SNOPR analysis for gas cooking tops. 88 FR 
12603. DOE provided further data on the gas cooking top test sample 
used for the February 2023 SNOPR analysis and estimated that currently 
available gas cooking tops representing nearly half of the market would 
already meet the standards that were proposed in the February 2023 
SNOPR, and therefore would not be impacted by the proposed standard, if 
finalized. 88 FR 12603, 12605.
    In response to the February 2023 SNOPR, DOE received additional 
data and information regarding consumer conventional cooking products. 
Specifically, DOE received additional gas and electric cooking top test 
data from the Association of Home Appliance Manufacturers (``AHAM'') 
and Pacific Gas and Electric (``PG&E'').\3\ Stakeholders also provided 
substantive information regarding gas cooking top features that are 
desired by consumers. In addition, AHAM provided shipment estimates of 
gas and electric cooking tops by product type and/or configuration. 
(AHAM, No. 2285 at pp. 6, 27)
---------------------------------------------------------------------------

    \3\ The AHAM comment containing its data set is available at 
www.regulations.gov/comment/EERE-2014-BT-STD-0005-2285. The PG&E 
data was provided confidentially to DOE's contractor.
---------------------------------------------------------------------------

    Upon consideration of further information received from interested 
parties in response to the February 2023 SNOPR, this NODA presents 
updated efficiency levels, manufacturer production costs, no-new-
standards-case market shares, life-cycle costs (``LCC''), payback 
periods (``PBP''), and national impact analysis (``NIA'') results for 
all consumer conventional cooking products. DOE is requesting comments, 
data, and information regarding the updated analysis.
    DOE notes that it is continuing to consider all of the stakeholder 
comments received in response to the February 2023 SNOPR and the 
February 2023 NODA in further development of the rulemaking.

II. Discussion

    In the following sections, DOE details its updated analysis for 
consumer conventional cooking products. As discussed in the February 
2023 SNOPR, DOE has not identified any higher efficiency levels for 
electric open (coil) element cooking tops and as such, is not including 
them in this NODA.

A. Efficiency Levels

1. Electric Cooking Tops
    In the February 2023 SNOPR, DOE established efficiency levels for 
electric smooth element cooking tops based on combining an active-mode 
annual energy consumption (``AEC'') value and a combined low-power mode 
annual energy consumption (``ETLP'') value associated with 
specific design options, noting that different combinations of AEC and 
ETLP could be used to meet the IAEC of a given efficiency 
level. 88 FR 6818, 6845-6846. DOE received additional electric smooth 
element cooking top test data from AHAM and PG&E in response to the 
February 2023 SNOPR. These additional data are consistent with DOE's 
tentative determination in the February 2023 SNOPR regarding efficiency 
levels for these products. Therefore, in this NODA, DOE maintains the 
efficiency levels for electric smooth element cooking tops that were 
proposed in the February 2023 SNOPR. Table II.1 shows the efficiency 
levels for electric smooth element cooking tops.

    DOE requests comment on the efficiency levels for electric smooth 
element cooking tops.
2. Gas Cooking Tops
    In the February 2023 SNOPR, DOE proposed new and amended energy 
conservation standards for consumer conventional cooking products. Per 
its authority in 42 U.S.C. 6295(h)(2), DOE proposed to remove the 
existing prescriptive standard for gas cooking tops prohibiting a 
constant burning pilot light. 88 FR 6818, 6819. Instead, for gas 
cooking tops, DOE proposed a performance standard of a maximum 
allowable IAEC of 1,204 kBtu/year. 88 FR 6818, 6819-6820. These 
proposed standards for conventional cooking tops, if adopted, would 
apply to all gas cooking tops manufactured in, or imported into, the 
United States starting on the date 3 years after the publication of any 
final rule for this rulemaking. 88 FR 6818, 6819.
    For the February 2023 SNOPR, DOE considered efficiency levels 
(``ELs'') associated with an optimized burner and grate design, but 
only insofar as the efficiency level was achievable with continuous 
cast-iron grates and at least one high input rate (``HIR'') burner 
(which DOE defined in the February 2023 SNOPR as burners with input 
rates greater than or equal to 14,000 British thermal units per hour 
(``Btu/h'')). 88 FR 6818, 6845. DOE's testing showed that energy use 
was correlated to burner design and cooking top configuration (e.g., 
grate weight, flame angle, distance from burner ports to the cooking 
surface) and could be reduced by optimizing the design of the burner 
and grate system. Id. DOE reviewed the test data for the gas cooking 
tops in its test sample and identified two efficiency levels associated 
with improving the burner and grate design that corresponded to 
different design criteria. Id.
    In the February 2023 SNOPR, DOE established efficiency levels for 
gas cooking tops based on combining an AEC value and an ETLP 
value associated with specific design options, noting that different 
combinations of AEC and ETLP could be used to meet the IAEC 
of a given efficiency level. 88 FR 6818, 6845-6846.

[[Page 50812]]

    In the February 2023 SNOPR, DOE set the baseline gas cooking top 
IAEC equal to the sum of the maximum AEC and the maximum 
ETLP observed in its test sample for gas cooking tops. 88 FR 
6818, 6844.
    In the February 2023 SNOPR, DOE defined EL 1 based on an AEC 
achievable by a gas cooking top with four or more HIR burners and 
continuous cast-iron grates and the same ETLP as used for 
the baseline efficiency level. 88 FR 6818, 6845-6846. The AEC selected 
for EL 1 was the highest measured among the units in its test sample 
with four or more HIR burners and continuous cast-iron grates, as shown 
in Table 5.5.2 in chapter 5 of the TSD for the February 2023 SNOPR.\5\
---------------------------------------------------------------------------

    \5\ Available at www.regulations.gov/document/EERE-2014-BT-STD-0005-0090.
---------------------------------------------------------------------------

    In the February 2023 SNOPR, DOE defined EL 2 based on the highest 
measured AEC measured among the units in its test sample with at least 
one HIR burner and continuous cast-iron grates and the same 
ETLP as used for the baseline efficiency level. 88 FR 6818, 
6845-6846. In the February 2023 SNOPR, DOE stated that HIR burners 
provide unique consumer utility and allow consumers to perform high 
heat cooking activities such as searing and stir-frying. Id. at 88 FR 
6845. DOE also stated that it is aware that some consumers derive 
utility from continuous cast-iron grates, such as the ability to use 
heavy pans, or to shift cookware between burners without needing to 
lift them. Id. DOE notes that EL 2 was defined based on the highest 
measured efficiency unit that met the screening analysis criteria 
(i.e., gas cooking tops that include at least one HIR burner and 
continuous cast-iron grates), rather than the highest measured 
efficiency unit of all tested units, so that all ELs would be 
achievable with continuous cast-iron grates and at least one HIR 
burner.
    Table II.2 shows the efficiency levels for gas cooking tops 
evaluated in the February 2023 SNOPR. Id. at 88 FR 6846.

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

    As discussed in section I of this document, DOE received additional 
gas cooking top test data from AHAM and PG&E that has prompted DOE to 
review the engineering analysis for gas cooking tops as presented in 
the February 2023 SNOPR. The additional gas cooking top test data 
provided to DOE includes a unit with a more energy consumptive AEC 
value and a different unit with a more energy consumptive maximum 
ETLP value than the most energy consumptive values in DOE's 
gas cooking top test sample. As discussed, in the February 2023 SNOPR, 
DOE established efficiency levels for gas cooking tops based on 
combining the AEC value associated with specific cooking top 
characteristics and the maximum ETLP value in DOE's test 
sample, to avoid any potential loss of utility from setting a standard 
based on a unit without clock functionality.
    DOE is publishing the full expanded test sample for gas cooking 
tops (including the stakeholder-provided data) in an attachment to this 
NODA, available in the docket for this rulemaking.\6\
---------------------------------------------------------------------------

    \6\ www.regulations.gov/docket/EERE-2014-BT-STD-0005/document.
---------------------------------------------------------------------------

    As discussed, in the February 2023 SNOPR, DOE used the maximum 
ETLP value in its test sample to define the ELs for gas 
cooking tops. In this NODA, DOE is updating the ETLP 
estimate at each EL for gas cooking tops to be equal to the average of 
the non-zero ETLP values measured in the expanded test 
sample. ETLP ranged from 6-57 kBtu/year, with one additional 
outlier at 101 kBtu/year. Upon closer examination of the data, DOE has 
tentatively determined that the ETLP value used in the SNOPR 
was unrepresentative for use in defining the ELs. Instead, DOE has 
tentatively determined that a more representative ETLP value 
to use in determining each efficiency level would be the average of the 
non-zero ETLP values in the test sample. Through a close 
examination of the control functionality associated with various 
standby levels, DOE has tentatively determined that using the non-zero 
average ETLP value would not preclude gas standalone cooking 
tops or gas ranges with electronic controls and/or displays from 
achieving any potential standard level.
    In response to the February 2023 SNOPR and February 2023 NODA, 
stakeholders provided substantive information regarding gas cooking top 
features that are desired by consumers. A review of these stakeholder 
comments has led DOE to better understand what features some consumers 
value, including: the presence of multiple HIR burners; continuous 
cast-iron grates; the ability to choose between nominal unit widths; 
burner type (open versus sealed burners); at least one low input rate 
burner (i.e., rated below 5,000 Btu/h); the ability to have multiple 
dual-stacked and/or multi-ring HIR burners; and at least one extra-high 
input rate burner (i.e., rated above 18,000 Btu/h).
    In this NODA, therefore, DOE is updating its definition of the max-
tech efficiency level to be based on the most efficient AEC value in 
its expanded test sample achievable with continuous cast-iron grates 
and multiple HIR burners, rather than the single HIR burner utility 
defined in the February 2023 SNOPR. DOE's data show that among the gas 
cooking tops in the expanded test sample, units with two to six HIR 
burners can also achieve this EL and that the updated EL 2 can be 
achieved by a gas cooking top with all HIR burners.
    As discussed, in the February 2023 SNOPR, DOE defined EL 1 based on 
the optimized burner/grate design option yielding the most energy 
efficient AEC achievable with at least four HIR burners and continuous 
cast-iron grates. In this NODA, DOE is updating its definition of EL 1 
to represent the most energy efficient AEC among units with multiple 
(up to six) HIR burners and continuous cast-iron grates that would not 
preclude any combination of the other features mentioned by 
manufacturers (including different nominal unit widths, at least one 
low input rate burner, all HIR burners, multiple dual-stacked and/or 
multi-ring HIR burners, and at least one extra-high input rate burner), 
as demonstrated by products from multiple manufacturers in DOE's 
expanded test sample.
    As discussed, in the February 2023 SNOPR, DOE tentatively 
determined the baseline cooking top AEC as the maximum value observed 
in its test sample. In this NODA, DOE is updating the baseline 
efficiency level for gas cooking tops by applying the same methodology 
as was used in the engineering analysis for the February 2023 SNOPR to 
the expanded test sample. Using the expanded test sample, DOE is 
setting a higher baseline IAEC value, corresponding to a lower 
efficiency.
    Table II.3 shows the efficiency levels for gas cooking tops that 
DOE evaluated for this NODA.

3. Conventional Ovens
    As discussed in the February 2023 SNOPR, there are no current test 
procedures for conventional ovens. 88 FR 6818, 6846. Therefore, DOE 
considered only efficiency levels corresponding to prescriptive design 
requirements as defined by the design options developed as part of the 
screening analysis: forced convection, the use of a switch-mode power 
supply (``SMPS''), and an oven separator. Id. DOE ordered the design 
options by incremental manufacturer production cost (``MPC''). Id. In 
this NODA, DOE maintains the efficiency levels for conventional ovens 
that were proposed in the February 2023 SNOPR. Table II.4 and Table 
II.5 define the efficiency levels for conventional electric and gas 
ovens, respectively.

B. Manufacturer Production Costs

1. Electric Cooking Tops
    For the February 2023 SNOPR, DOE developed cost-efficiency results 
for electric smooth element cooking tops based on manufacturing cost 
modeling of units in its sample featuring the design options. 88 FR 
6818, 6850. In this NODA, DOE maintains the incremental MPCs for 
electric smooth element cooking tops that were proposed in the February 
2023 SNOPR, as shown in Table II.6.

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

    DOE is requesting comment, data, and information on the incremental 
manufacturer production costs for electric smooth element cooking tops.
2. Gas Cooking Tops
    For the February 2023 SNOPR, DOE developed the incremental MPCs 
associated with each efficiency levels shown in Table II.7. 88 FR 6818, 
6850-6851. DOE developed incremental MPCs based on manufacturing cost 
modeling of units in its sample featuring the design options. Id.
    As discussed, in the February 2023 SNOPR, DOE evaluated two 
versions of the optimized burner and grate design option, 
representative of a minimum of either four or one HIR burners. Id. 
DOE's testing showed that decreased energy use could be correlated to 
burner design and cooking top configuration (e.g., grate weight, flame 
angle, distance from burner ports to the cooking surface). Id. Because 
this design option effectively corresponds to a whole burner and grate 
system redesign, regardless of the efficiency level achieved by the 
redesign, DOE stated that the incremental costs for EL 1 and for EL 2 
for gas cooking tops include the cost for redesigning the combination 
of each burner and grate configuration. Id. Therefore, DOE stated that 
it was not able to determine different incremental costs for EL 1 and 
EL 2 for gas cooking tops. Id.

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

    In this NODA, DOE is updating the MPCs for gas cooking tops based 
on its understanding of the different types of burner and grate 
redesign likely to be needed to achieve each of the revised ELs, using 
the same underlying data as was used in the February 2023 SNOPR.
    DOE's analysis shows that the incremental MPC developed in the 
February 2023 SNOPR, $12.41, representing the optimized burner and 
grate design option (e.g., grate weight, flame angle, distance from 
burner ports to the cooking surface), accurately represents the cost to 
redesign a unit at EL 1 to meet EL 2.
    To develop the incremental MPC between the updated baseline and EL 
1, DOE analyzed the test data in its expanded test sample which shows 
that cooking tops at the baseline efficiency level typically include 
one or two burners with ``non-optimized'' turndown capability (i.e., 
the lowest available simmer setting is more energy consumptive than 
necessary to hold the test load in a constant simmer close to 90 
degrees Celsius, resulting in significantly higher energy consumption 
than for a burner with a simmer setting that holds the test load close 
to that temperature). In this NODA, DOE estimates that the cost of 
implementing a burner with optimized turndown capability in place of a 
burner with non-optimized turndown capability to meet typical 
efficiencies available in the market is smaller than the cost of an 
entirely redesigned burner and grate system (associated with the 
incremental MPC between EL 1 and EL 2). DOE estimates that the 
percentage of burners with non-optimized turndown capability (defined 
empirically from the expanded test sample as burners with a specific 
energy use of more than 1.45 Btu per gram of water in the test load, as 
measured by appendix I1) in the baseline units in its expanded test 
sample ranged from 16 percent (one out of six burners) to 40 percent 
(two out of five burners). In order to conservatively assess the 
incremental MPC between baseline and EL 1, DOE defined it as 40 percent 
of the $12.41 incremental MPC between EL 1 and EL 2, or $4.96.
    In sum, for this NODA, DOE developed the incremental MPCs relative 
to the baseline associated with the updated efficiency levels shown in 
Table II.8.

C. Market Distribution

1. Electric Cooking Tops
    In the February 2023 SNOPR, DOE estimated the efficiency 
distribution for each cooking top product class from the sample of 
cooking tops used to develop the engineering analysis. 88 FR 6818, 
6856. Given the lack of data on historic efficiency trends, DOE assumed 
that the estimated current distributions would apply in 2027. Id. The 
estimated market shares for the no-new-standards case for electric 
smooth element cooking tops in 2027 used in the February 2023 SNOPR are 
shown in Table II.11. 88 FR 6818, 6857.

    In its comment on the February 2023 SNOPR, AHAM provided shipment 
estimates of electric cooking tops by product type (i.e., open (coil) 
element versus electric smooth resistance versus induction).\7\ The 
AHAM shipment data specified that of electric smooth element cooking 
top shipments, 93.8 percent use resistance heating elements, and 6.2 
percent use induction heating elements. AHAM also provided shipment 
estimates of electric cooking tops by configuration (i.e., standalone 
cooking top versus conventional range). The AHAM shipment data 
specified that 93.4 percent of electric cooking tops are sold as 
components of conventional ranges.

    Combining these percentages, DOE estimates the current market 
distributions for electric smooth element cooking tops by product 
categories as shown in Table II.12.

                            Product Category

    To calculate the no-new-standards case market shares, DOE first 
determined the efficiency level and category of each unit in its 
expanded test sample, then applied the appropriate weighting factors to 
adjust the efficiency level distribution of the test sample to a market 
share distribution representing the full market.

2. Gas Cooking Tops
    In the February 2023 SNOPR analysis, DOE's estimate of the current 
market share of gas cooking tops that meet each efficiency level under 
consideration reflected the exclusion of higher-efficiency products 
that DOE had screened out (i.e., excluded products that do not have at 
least one HIR burner and continuous cast-iron grates). (See Table 
8.2.43 in chapter 8 of the TSD for the February 2023 SNOPR). In the 
February 2023 NODA, DOE clarified that it has tentatively determined 
that gas cooking tops with steel grates, non-continuous grates, and/or 
burners with input rates less than 14,000 Btu/h would also be able to 
meet the efficiency levels described in the February 2023 SNOPR and 
therefore would not be impacted by the proposed standard, if finalized. 
88 FR 12603, 12604. Based on its testing results and model counts of 
the burner/grate configurations of gas cooking top models currently 
available on the websites of major U.S. retailers, DOE estimated in the 
February 2023 NODA that the products that were screened out of the 
engineering analysis for the February 2023 SNOPR represent over 40 
percent of the market. 88 FR 12603, 12605. Together with the models 
included in the engineering analysis, DOE estimated that nearly half of 
the total gas cooking top market currently achieves the proposed EL 2 
and therefore would not be impacted by the proposed standard, if 
finalized. Id. DOE estimated that the remaining portion of the total 
market was distributed equally between the baseline and EL 1. Id.
    In its comment on the February 2023 SNOPR, AHAM provided shipment 
estimates of gas cooking tops by configuration (i.e., standalone 
cooking top versus conventional range).\8\ According to AHAM's shipment 
data,

[[Page 50815]]

86.7 percent of gas cooking tops are sold as components of conventional 
ranges.
---------------------------------------------------------------------------

    \8\ Available at www.regulations.gov/document/EERE-2014-BT-STD-0005-2285.
---------------------------------------------------------------------------

    For this NODA, DOE confirmed the estimate of the products that were 
screened out of the February 2023 SNOPR engineering analysis based on a 
thorough, model-by-model evaluation of these specific features on 
online retailer websites. DOE notes that these models represent 
``entry-level'' products that feature steel grates, non-continuous 
grates, and/or burners with input rates less than 14,000 Btu/h. DOE 
notes that these are typically the lowest-cost products available in 
the market, and are typically purchased by price-sensitive consumers.
    Combining these percentages, DOE estimates the current market 
distributions for gas cooking tops by product categories as shown in 
Table II.14.

    To calculate the no-new-standards case market shares, DOE first 
determined the efficiency level and category of each unit in its 
expanded test sample, then applied the appropriate weighting factors to 
adjust the efficiency level distribution of the test sample to a market 
share distribution representing the full market.

of data on historic efficiency trends, DOE assumed that the estimated 
current distributions would apply in 2027. Id. The estimated market 
shares for the no-new-standards case for gas and electric ovens in 2027

D. Life-Cycle Cost and Payback Period Analysis

    DOE conducted LCC and PBP analyses to evaluate the economic impacts 
on individual consumers of potential energy conservation standards for 
the gas cooking top efficiency levels presented in this NODA. For this 
NODA analysis, DOE used the same inputs and assumptions as in the 
February 2023 SNOPR LCC analysis, including using the 2015 Residential 
Energy Consumption Survey (``2015 RECS'') \9\ as the basis for the 
consumer sample and Energy Information Administration's (``EIA's'') 
Annual Energy Outlook 2022 (``AEO 2022'') \10\ for energy price 
projections. Details of the analysis inputs and methodology are 
available in chapter 8 of the TSD for the February 2023 SNOPR 
analysis.\11\ Subsequent rulemaking analyses will be updated with the 
most recent data releases (e.g., 2020 RECS, AEO 2023).

    \11\ Available at www.regulations.gov/document/EERE-2014-BT-STD-0005-0090.
---------------------------------------------------------------------------

    The results of this NODA analysis are presented in Table II.18 
through Table II.37. In the first of each pair of tables, the simple 
payback is measured relative to the baseline product. In the second 
table, impacts are measured relative to the efficiency distribution in 
the no-new-standards case in the compliance

year (see section II.C of this document). Because some consumers 
purchase products with higher efficiency in the no-new-standards case, 
the average savings are less than the difference between the average 
LCC of the baseline product and the average LCC at each EL. The savings 
refer only to consumers who are affected by a standard at a given 
EL.\12\ Those who already purchase a product with efficiency at or 
above a given EL are not affected. Consumers for whom the LCC increases 
at a given EL experience a net cost.
---------------------------------------------------------------------------

    \12\ LCC savings presented in the February 2023 SNOPR were 
mislabeled as only including impacted consumers; however, they also 
included unimpacted consumers. The values in this NODA have been 
updated to reflect only impacted consumers to be consistent with 
current DOE rulemakings.

E. National Impact Analysis

    The NIA assesses the national energy savings (``NES'') and the net 
present value (``NPV'') from a national perspective of total consumer 
costs and savings that would be expected to result from new or amended 
standards at specific efficiency levels. In this section, DOE presents 
the NIA results analyzing the impacts of the updated analysis discussed 
in this NODA. As in the LCC analysis, DOE maintained the same 
methodologies and assumptions presented in the February 2023 SNOPR 
analysis, including using estimates from 2015 RECS and AEO 2022 
projections. Details of the NIA analysis are available in chapter 10 of 
the TSD for the February 2023 SNOPR. Subsequent rulemaking analyses 
will be updated with most recent data releases (e.g., 2020 RECS, AEO 
2023).
    Table II.38 shows full-fuel cycle NES results of a potential 
standard at each efficiency level. Full-fuel cycle national energy 
savings are presented in quadrillion British thermal units, or quads. 
Table II.39 and Table II.40 show NPV results at each considered 
efficiency level, discounted at 3 and 7 percent, respectively.

include it in the comment itself or in any documents attached to your 
comment. Any information that you do not want to be publicly viewable 
should not be included in your comment, nor in any document attached to 
your comment. Persons viewing comments will see only first and last 
names, organization names, correspondence containing comments, and any 
documents submitted with the comments.
    Do not submit to www.regulations.gov information for which 
disclosure is restricted by statute, such as trade secrets and 
commercial or financial information (hereinafter referred to as 
Confidential Business Information (``CBI'')). Comments submitted 
through www.regulations.gov cannot be claimed as CBI. Comments received 
through the website will waive any CBI claims for the information 
submitted. For information on submitting CBI, see the Confidential 
Business Information section.
    DOE processes submissions made through www.regulations.gov before 
posting. Normally, comments will be posted within a few days of being 
submitted. However, if large volumes of comments are being processed 
simultaneously, your comment may not be viewable for up to several 
weeks. Please keep the comment tracking number that www.regulations.gov 
provides after you have successfully uploaded your comment.
    Submitting comments via email. Comments and documents submitted via 
email also will be posted to www.regulations.gov. If you do not want 
your personal contact information to be publicly viewable, do not 
include it in your comment or any accompanying documents. Instead, 
provide your contact information in a cover letter. Include your first 
and last names, email address, telephone number, and optional mailing 
address. The cover letter will not be publicly viewable as long as it 
does not include any comments.
    Include contact information each time you submit comments, data, 
documents, and other information to DOE. No telefacsimiles (``faxes'') 
will be accepted.
    Comments, data, and other information submitted to DOE 
electronically should be provided in PDF (preferred), Microsoft Word or 
Excel, WordPerfect, or text (ASCII) file format. Provide documents that 
are not secured, that are written in English, and that are free of any 
defects or viruses. Documents should not contain special characters or 
any form of encryption and, if possible, they should carry the 
electronic signature of the author.
    Campaign form letters. Please submit campaign form letters by the 
originating organization in batches of between 50 to 500 form letters 
per PDF or as one form letter with a list of supporters' names compiled 
into one or more PDFs. This reduces comment processing and posting 
time.
    Confidential Business Information. Pursuant to 10 CFR 1004.11, any 
person submitting information that he or she believes to be 
confidential and exempt by law from public disclosure should submit via 
email two well-marked copies: one copy of the document marked 
``confidential'' including all the information believed to be 
confidential, and one copy of the document marked ``non-confidential'' 
with the information believed to be confidential deleted. DOE will make 
its own determination about the confidential status of the information 
and treat it according to its determination.
    It is DOE's policy that all comments may be included in the public 
docket, without change and as received, including any personal 
information provided in the comments (except information deemed to be 
exempt from public disclosure).
