D. Commenting on the Proposed Confidentiality Determinations

    We seek comment on the proposed confidentiality status of data
elements in two direct emitter data categories: ``Unit/Process `Static'
Characteristics that Are Not Inputs to Emission Equations'' and ``Unit/
Process Operating Characteristics that Are Not Inputs to Emission
Equations''. By the EPA's proposing confidentiality determinations
prior to data reporting through this proposal and rulemaking process,
we provide potential reporters an opportunity to submit comments
identifying data they consider sensitive and the rationales and
supporting documentation, the same as those they would otherwise submit
for case-by-case confidentiality determinations. We will evaluate
claims of confidentiality before finalizing the confidentiality
determinations. Please note that this will be reporters' only
opportunity to substantiate your confidentiality claim. Once finalized,
the EPA will release or withhold subpart W data in accordance with 40
CFR 2.301, which contains special provisions governing the treatment of
Part 98 data for which confidentiality determinations have been made
through rulemaking. Please consider the following instructions in
submitting comments on the data elements in subpart W.
    Please identify each individual data element you do or do not
consider to be CBI or emission data in your comments. Please explain
specifically how the public release of that particular data element
would or would not cause a competitive disadvantage to a facility.
Discuss how this data element may be different from or similar to data
that are already publicly available. Please submit information
identifying any publicly available sources of information containing
the specific data elements in question, since data that are already
available through other sources would not be proposed as CBI. In your
comments, please identify the manner and location in which each
specific data element you identify is available, including a citation.
If the data are physically published, such as in a book, industry trade
publication, or federal agency publication, provide the title, volume
number (if applicable), author(s), publisher, publication date, and
ISBN or other identifier. For data published on a Web site, provide the
address of the Web site and the date you last visited the Web site and
identify the Web site publisher and content author.
    If your concern is that competitors could use a particular input to
discern sensitive information, specifically describe the pathway by
which this could occur and explain how the discerned information would
negatively affect your competitive position. Describe any unique
process or aspect of your facility that would be revealed if the
particular data element(s) you consider sensitive were made publicly
available. If the data element you identify would cause harm only when
used in combination with other publicly available data, then describe
the other data, identify the public source(s) of these data, and
explain how the combination of data could be used to cause competitive
harm. Describe the measures currently taken to keep the data
confidential. Avoid conclusory and unsubstantiated statements, or
general assertions regarding potential harm. Please be as specific as
possible in your comments and include all information necessary for the
EPA to evaluate your comments.

IV. Proposed Deferral of Inputs to Emission Equations for Subpart W and
Amendments to Table A-7

    Of the 154 subpart W data elements that were revised in the Subpart
W Technical Revisions Rule, 30 are ``Inputs to Emission Equations''.
All 30 are revisions to existing ``Inputs to Emission Equations'' that
were addressed in the Final Deferral and included in Table A-7 to
subpart A of Part 98. For the 30 revised inputs, the revisions did not
change the type of information to be reported to the EPA under these
requirements. For 19 of the 30 inputs, the changes included minor
wording changes such as requiring certain data elements be reported by
``sub-basin'' instead of ``field'' or small clarifications that did not
change the general meaning of the data elements. For 11 of the 30
inputs, the Technical Revisions Rule re-numerated the section
references. We are therefore proposing in this action to amend Table A-
7 of Part 98 by re-numerating these 11 subpart W ``Inputs to Emission
Equations'' as finalized in the Subpart W Technical Revisions Rule.
    The Subpart W Technical Revisions Rule also added the following 10
new data elements, which we are proposing

to assign to the ``Inputs to Emission Equations'' data category and to
defer their reporting until March 31, 2015. The proposed inputs include
the following 10 data elements:
     Annual quantity of CO2, that was recovered from
each acid gas removal unit and transferred outside the facility (metric
tons CO2e), under subpart PP of this part. (40 CFR
98.236(c)(3)(iv))
     Blowdown vent stack emission source, for each unique
physical volume that is blown down more than once during the calendar
year: Report total number of blowdowns for each unique physical volume
in the calendar year (when using Eq. W-14A). (40 CFR
98.236(c)(7)(i)(A))
     Wellhead gas-liquid separator with oil throughput greater
than or equal to 10 barrels per day, using Calculation Methodology 1 of
40 CFR 98.233(j), report by sub-basin category: Annual CO2
gas quantities that were recovered (metric tons CO2e), for
all wellhead gas-liquid separators or storage tanks using Calculation
Methodology 1 of 40 CFR 98.233(j). (40 CFR 98.236(c)(8)(i)(K))
     Wellhead gas-liquid separator with oil throughput greater
than or equal to 10 barrels per day, using Calculation Methodology 1 of
40 CFR 98.233(j), report by sub-basin category: Report annual
CH4 gas quantities that were recovered (metric tons
CO2e), for all wellhead gas-liquid separators or storage
tanks using Calculation Methodology 1 of 40 CFR 98.233(j). (40 CFR
98.236(c)(8)(i)(K))
     Wellhead gas-liquid separator with oil throughput greater
than or equal to 10 barrels per day, using Calculation Methodology 2 of
40 CFR 98.233(j), report by sub-basin category: Report annual
CO2 gas quantities that were recovered (metric tons
CO2e), for all wellhead gas-liquid separators or storage
tanks using Calculation Methodology 2 of 40 CFR 98.233(j). (40 CFR
98.236(c)(8)(i)(K))
     Wellhead gas-liquid separator with oil throughput greater
than or equal to 10 barrels per day, using Calculation Methodology 2 of
40 CFR 98.233(j), report by sub-basin category: Report annual
CH4 gas quantities that were recovered (metric tons
CO2e), for all wellhead gas-liquid separators or storage
tanks using Calculation Methodology 2 of 40 CFR 98.233(j). (40 CFR
98.236(c)(8)(i)(K))
     Wells with oil production greater than or equal to 10
barrels per day, using Calculation Methodology 3 and 4 of 40 CFR
98.233(j), report the following by sub-basin category: Report annual
CO2 gas quantities that were recovered (metric tons
CO2e), for Calculation Methodology 3 or 4 of 40 CFR
98.233(j). (40 CFR 98.236(c)(8)(ii)(H))
     Wells with oil production greater than or equal to 10
barrels per day, using Calculation Methodology 3 and 4 of 40 CFR
98.233(j), report the following by sub-basin category: Report annual
CH4 gas quantities that were recovered (metric tons
CO2e), for Calculation Methodology 3 or 4 of 40 CFR
98.233(j). (40 CFR 98.236(c)(8)(ii)(H))
     Wellhead gas-liquid separators and wells with throughput
less than 10 barrels per day, using Calculation Methodology 5 of 40 CFR
98.233(j), Equation W-15 of 40 CFR 98.233: Annual CO2 gas
quantities that were recovered (metric tons CO2e), at the
sub-basin level for Calculation Methodology 5 of 40 CFR 98.233(j). (40
CFR 98.236(c)(8)(iii)(G))
     Wellhead gas-liquid separators and wells with throughput
less than 10 barrels per day, using Calculation Methodology 5 of 40 CFR
98.233(j), Equation W-15 of 40 CFR 98.233: Report annual CH4
gas quantities that were recovered (metric tons CO2e), at
the sub-basin level for Calculation Methodology 5 of 40 CFR 98.233(j).
(40 CFR 98.236(c)(8)(iii)(G))
    As explained in Section II.A of the Final Deferral, these 10 data
elements are related to and therefore are being evaluated together
along with the other subpart W data elements assigned to this category.
As with the other equation inputs, we believe that to complete our
evaluation we will need until March 31, 2015, the current reporting
deadline for subpart W equation inputs. The EPA is therefore proposing
to add these 10 inputs to Table A-7 of Part 98 to require their
reporting by March 31, 2015. For more information, please refer to
Section II.B. of this preamble.
    We are also proposing to move 21 data elements that were
categorized as ``Inputs to Emission Equations'' in the Final Deferral
Rule to other categories. These data elements require aggregated data
to be reported and not the specific values used in the equations.
Therefore, the EPA is proposing to re-categorize these data elements as
either ``Unit/Process `Static' Characteristics that Are Not Inputs to
Emission Equations'' or ``Unit/Process Operating Characteristics that
Are Not Inputs to Emission Equations''. Please see the memorandum
entitled ``Proposed Changes to Subpart W Inputs'' in Docket ID No. EPA-
HQ-OAR-2011-0028 for a comparison of the changes to Table A-7 of
subpart A for subpart W data reporting elements.

V. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review

    In this action, we are proposing to (1) Make confidentiality
determinations for subpart W data elements (except for inputs to
equations); and (2) make the changes described in this notice regarding
subpart W data elements in Table A-7 of Part 98, which specifies the
data elements to be reported by March 31, 2015.
    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
action is not a ``significant regulatory action'' under the terms of
Executive Order 12866 (58 FR 51735, October 4, 1993) and is therefore
not subject to review under Executive Orders 12866 and 13563 (76 FR
3821, January 21, 2011).

B. Paperwork Reduction Act

    As previously mentioned, this action proposes confidentiality
determinations for subpart W data elements (except for inputs to
equations) and amendments to Table A-7 of Part 98. This action does not
impose any new information collection burden. This action does not
increase the reporting burden. The Office of Management and Budget
(OMB) has previously approved the information collection requirements
contained in subpart W, under 40 CFR part 98, under the provisions of
the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. The Information
Collection Request (ICR) documents prepared by the EPA have been
assigned OMB control number 2060-0651 for subpart W. The OMB control
numbers for EPA regulations in 40 CFR are listed at 40 CFR part 9.

C. Regulatory Flexibility Act (RFA)

    The RFA generally requires an agency to prepare a regulatory
flexibility analysis of any rule subject to notice and comment
rulemaking requirements under the Administrative Procedure Act or any
other statute unless the agency certifies that the rule will not have a
significant economic impact on a substantial number of small entities.
Small entities include small businesses, small organizations, and small
governmental jurisdictions.
    For purposes of assessing the impacts of this re-proposal on small
entities, ``small entity'' is defined as: (1) A small business as
defined by the Small Business Administration's regulations at 13 CFR
121.201; (2) a small governmental jurisdiction that is a government of
a city, county, town,

school district or special district with a population of less than
50,000; or (3) a small organization that is any not-for-profit
enterprise which is independently owned and operated and is not
dominant in its field.
    This action proposes confidentiality determinations for subpart W
data elements (except for inputs to equations) and amendments to Table
A-7 of Part 98. After considering the economic impacts of this action
on small entities, I certify that this action will not have a
significant economic impact on a substantial number of small entities.
This action will not impose any new requirement on small entities that
are not currently required by Part 98.
    The EPA took several steps to reduce the impact of Part 98 on small
entities. For example, the EPA determined appropriate thresholds that
reduced the number of small businesses reporting. In addition, the EPA
did not require facilities to install continuous emission monitoring
systems (CEMS) if they did not already have them. Facilities without
CEMS can calculate emissions using readily available data or data that
are less expensive to collect such as process data or material
consumption data. For some source categories, the EPA developed tiered
methods that are simpler and less burdensome. Also, the EPA required
annual instead of more frequent reporting. Finally, the EPA continues
to conduct significant outreach on the mandatory GHG reporting rule and
maintains an ``open door'' policy for stakeholders to help inform EPA's
understanding of key issues for the industries.
    We continue to be interested in the potential impacts of this
action on small entities and welcome comments on issues related to such
effects.

D. Unfunded Mandates Reform Act (UMRA)

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2
U.S.C. 1531-1538, requires federal agencies, unless otherwise
prohibited by law, to assess the effects of their regulatory actions on
state, local, and tribal governments and the private sector. Federal
agencies must also develop a plan to provide notice to small
governments that might be significantly or uniquely affected by any
regulatory requirements. The plan must enable officials of affected
small governments to have meaningful and timely input in the
development of EPA regulatory proposals with significant federal
intergovernmental mandates and must inform, educate, and advise small
governments on compliance with the regulatory requirements.
    This action, which is proposing confidentiality determinations for
subpart W data elements (except for inputs to equations) and amendments
to Table A-7 of Part 98, does not contain a federal mandate that may
result in expenditures of $100 million or more for state, local, and
tribal governments, in the aggregate, or the private sector in any one
year. This action does not increase the reporting burden. Thus, this
action is not subject to the requirements of sections 202 or 205 of the
UMRA.
    In developing Part 98, the EPA consulted with small governments
pursuant to a plan established under section 203 of the UMRA to address
impacts of regulatory requirements in the rule that might significantly
or uniquely affect small governments. For a summary of EPA's
consultations with state and/or local officials or other
representatives of state and/or local governments in developing Part
98, see Section VIII.D of the preamble to the final rule (74 FR 56370,
October 30, 2009).

E. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have
substantial direct effects on the states, on the relationship between
the national government and the states, or on the distribution of power
and responsibilities among the various levels of government, as
specified in Executive Order 13132. However, for a more detailed
discussion about how Part 98 relates to existing state programs, please
see Section II of the preamble to the final rule (74 FR 56266, October
30, 2009).
    This action, which is proposing confidentiality determinations for
subpart W data elements (except for inputs to equations) and amendments
to Table A-7 of Part 98, applies to facilities containing petroleum and
natural gas systems that directly emit greenhouses gases over 25,000
metric tons of CO2 equivalent. It does not apply to
governmental entities unless a government entity owns a facility that
directly emits greenhouse gases above threshold levels, so relatively
few government facilities would be affected. This action also does not
limit the power of states or localities to collect GHG data and/or
regulate GHG emissions. Thus, Executive Order 13132 does not apply to
this action.
    In the spirit of Executive Order 13132, and consistent with EPA
policy to promote communications between the EPA and state and local
governments, the EPA specifically solicits comment on this proposed
action from state and local officials. For a summary of EPA's
consultation with state and local organizations and representatives in
developing Part 98, see Section VIII.E of the preamble to the final
rule (74 FR 56371, October 30, 2009).

F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments

    This action, which is proposing confidentiality determinations for
subpart W data elements (except for inputs to equations) and amendments
to Table A-7 of Part 98, does not have tribal implications, as
specified in Executive Order 13175 (65 FR 67249, November 9, 2000).
This action does not increase the reporting burden. Thus, Executive
Order 13175 does not apply to this action. For a summary of EPA's
consultations with tribal governments and representatives, see Section
VIII.F of the preamble to the final rule (74 FR 56371, October 30,
2009). The EPA specifically solicits additional comment on this
proposed action from tribal officials.

G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks

    The EPA interprets Executive Order 13045 (62 FR 19885, April 23,
1997) as applying only to those regulatory actions that concern health
or safety risks, such that the analysis required under section 5-501 of
the Executive Order has the potential to influence the regulation. This
action, which is proposing confidentiality determinations for subpart W
data elements (except for inputs to equations) and amendments to Table
A-7 of Part 98, is not subject to Executive Order 13045 because it does
not establish an environmental standard intended to mitigate health or
safety risks.

H. Executive Order 13211: Actions That Significantly Affect Energy
Supply, Distribution, or Use

    This action, which is proposing confidentiality determinations for
subpart W data elements (except for inputs to equations) and amendments
to Table A-7 of Part 98, is not subject to Executive Order 13211 (66 FR
28355, May 22, 2001), because it is not a significant regulatory action
under Executive Order 12866 .

I. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Public Law 104-113 (15 U.S.C. 272 note) directs
the EPA

to use voluntary consensus standards in its regulatory activities
unless to do so would be inconsistent with applicable law or otherwise
impractical. Voluntary consensus standards are technical standards
(e.g., materials specifications, test methods, sampling procedures, and
business practices) that are developed or adopted by voluntary
consensus standards bodies. NTTAA directs the EPA to provide Congress,
through OMB, explanations when the agency decides not to use available
and applicable voluntary consensus standards.
    This action, which is proposing confidentiality determinations for
subpart W data elements (except for inputs to equations) and amendments
to Table A-7 of Part 98, does not involve technical standards.
Therefore, the EPA is not considering the use of any voluntary
consensus standards.

J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations

    Executive Order 12898 (59 FR 7629, February 16, 1994) establishes
federal executive policy on environmental justice. Its main provision
directs federal agencies, to the greatest extent practicable and
permitted by law, to make environmental justice part of their mission
by identifying and addressing, as appropriate, disproportionately high
and adverse human health or environmental effects of their programs,
policies, and activities on minority populations and low-income
populations in the United States. The EPA has determined that this
action, which is proposing confidentiality determinations for subpart W
data elements (except for inputs to equations) and amendments to Table
A-7 of Part 98, will not have disproportionately high and adverse human
health or environmental effects on minority or low-income populations
because it does not affect the level of protection provided to human
health or the environment. This action addresses only reporting and
recordkeeping procedures.
