Proposed Confidentiality Determinations for the Petroleum and 
Natural Gas Systems Source Category, and Amendments to Table A-7, of 
the Greenhouse Gas Reporting Rule

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: This action re-proposes confidentiality determinations for the 
data elements in subpart W, the petroleum and natural gas systems 
category, of the Mandatory Reporting of Greenhouse Gases Rule. On July 
7, 2010, the EPA proposed confidentiality determinations for then-
proposed subpart W data elements and is now issuing this re-proposal 
due to significant changes to certain data elements in the final 
subpart W reporting requirements. The EPA is also proposing to assign 
10 recently added reporting elements as ``Inputs to Emission 
Equations'' and to defer their reporting deadline to March 31, 2015, 
consistent with the agency's approach in the August 25, 2011 rule which 
finalized the deferral of some reporting data elements that are inputs 
to emissions equations.

DATES: Comments. Comments must be received on or before March 26, 2012 
unless a public hearing is held, in which case comments must be 
received on or before April 9, 2012.
    Public Hearing. To request a hearing, please contact the person 
listed in the FOR FURTHER INFORMATION CONTACT section by March 2, 2012. 
Upon such request, the EPA will hold the hearing on March 12, 2012 in 
the Washington, DC area. The EPA will publish further information about 
the hearing in the Federal Register if a hearing is requested.

I. General Information

A. What is the purpose of this action?

    The EPA is re-proposing confidentiality determinations for the data 
elements in subpart W of 40 CFR part 98 of the Mandatory Reporting of 
Greenhouse Gases Rule (hereinafter referred to as ``Part 98''). Subpart 
W of Part 98 requires monitoring and reporting of greenhouse gas (GHG) 
emissions from petroleum and natural gas systems. The petroleum and 
natural gas systems source category (hereinafter referred to as 
``subpart W'') includes facilities that have emissions equal to or 
greater than 25,000 metric tons carbon dioxide equivalent 
(mtCO2e).
    The proposed confidentiality determinations in this notice cover 
all of the data elements that are currently in subpart W except for 
those that are in the ``Inputs to Emission Equations'' data category. 
The covered data elements and their proposed data category assignments 
are listed by data category in the memorandum entitled ``Proposed Data 
Category Assignments for Subpart W'' in Docket ID No. EPA-HQ-OAR-2011-
0028.
    This proposal also contains updates to Table A-7 of Part 98, the 
table of inputs to emission equations whose reporting deadline we have 
deferred until 2015. These data elements were added or revised to 
subpart W as a result of technical revisions made on December 23, 2011 
(76 FR 80554).

B. Does this action apply to me?

    This proposal affects entities that are required to submit annual 
GHG reports under subpart W of Part 98. Subpart W applies to facilities 
in eight segments of the petroleum and natural gas industry that emit 
GHGs greater than or equal to 25,000 metric tons of CO2 
equivalent per year. These eight segments are:
     Offshore petroleum and natural gas production (from 
offshore platforms).
     Onshore petroleum and natural gas production (including 
equipment on a single well-pad or associated with a single well pad 
used in the production, extraction, recovery, lifting, stabilization, 
separation or treating of petroleum and/or natural gas (including 
condensate).
     Onshore natural gas processing (separation of natural gas 
liquids (NGLs) or non-methane gases from produced natural gas, or the 
separation of NGLs into one or more component mixtures).
     Onshore natural gas transmission compression (use of 
compressors to move natural gas from production fields, natural gas 
processing plants, or other transmission compressors through 
transmission pipelines to natural gas distribution pipelines, LNG 
storage facilities, or into underground storage).
     Underground natural gas storage (subsurface storage of 
natural gas, natural gas underground storage processes and operations, 
and wellheads connected to the compression units located at the 
facility where injections and recovering of natural gas takes place 
into and from underground reservoirs).
     Liquefied natural gas (LNG) storage (onshore LNG storage 
vessels located above ground, equipment for liquefying natural gas, 
compressors to capture and re-liquefy boil-off-gas, re-condensers, and 
vaporization units for regasification of the liquefied natural gas).
     LNG import and export facilities (onshore and offshore 
equipment

[[Page 11041]]

importing or exporting LNG via ocean transport, including liquefaction 
of natural gas to LNG, storage of LNG, transfer of LNG, and re-
gasification of LNG to natural gas).
     Natural gas distribution (distribution pipelines and 
metering and regulating equipment at metering-regulating stations that 
re operated by a local distribution company (LDC) within a single state 
that is regulated as a separate operating company by a public utility 
commission or that is operated as an independent municipally-owned 
distribution system).
    For a summary of the source category definitions for subpart W, 
which includes further background on these eight industry segments, 
please see 40 CFR 98.230 of the subpart W final rule (75 FR 74490, 
November 30, 2010 and 76 FR 80554).
    The Administrator determined that this action is subject to the 
provisions of Clean Air Act (CAA) section 307(d). If finalized, these 
amended regulations could affect owners or operators of petroleum and 
natural gas systems. Regulated categories and entities may include 
those listed in Table 1 of this preamble:

    Table 1 of this preamble is not intended to be exhaustive, but 
rather provides a guide for readers regarding facilities likely to be 
affected by this action. Other types of facilities not listed in the 
table could also be affected. To determine whether you are affected by 
this action, you should carefully examine the applicability criteria 
found in 40 CFR part 98 subpart A, and subpart W. If you have questions 
regarding the applicability of this action to a particular facility, 
consult the person listed in the preceding FOR FURTHER INFORMATION 
CONTACT section.

C. Legal Authority

    The EPA is proposing rule amendments under its existing CAA 
authority, specifically authorities provided in CAA section 114. As 
stated in the preamble to the 2009 final rule (74 FR 56260, October 30, 
2009) and the Response to Comments on the Proposed Rule, Volume 9, 
Legal Issues, CAA section 114 provides the EPA broad authority to 
obtain the information in Part 98, including those in subpart W, 
because such data would inform and are relevant to the EPA's carrying 
out a wide variety of CAA provisions. As discussed in the preamble to 
the initial proposed Part 98 (74 FR 16448, April 10, 2009), CAA section 
114(a)(1) authorizes the Administrator to require emissions sources, 
persons subject to the CAA, manufacturers of control or process 
equipment, or persons whom the Administrator believes may have 
necessary information to monitor and report emissions and provide such 
other information the Administrator requests for the purposes of 
carrying out any provision of the CAA.

D. What should I consider as I prepare my comments to the EPA?

1. Submitting Comments That Contain CBI
    Clearly mark the part or all of the information that you claim to 
be CBI. For CBI information in a disk or CD ROM that you mail to the 
EPA, mark the outside of the disk or CD ROM as CBI and then identify 
electronically within the disk or CD ROM the specific information that 
is claimed as CBI. In addition to one complete version of the comment 
that includes information claimed as CBI, a copy of the comment that 
does not contain the information claimed as CBI must be submitted for 
inclusion in the public docket. Information marked as CBI will not be 
disclosed except in accordance with procedures set forth in 40 CFR part 
2.
    Do not submit information that you consider to be CBI or otherwise 
protected through http://www.regulations.gov or email. Send or deliver 
information identified as CBI to only the mail or hand/courier delivery 
address listed above, attention: Docket ID No. EPA-HQ-OAR-2011-0028.
    If you have any questions about CBI or the procedures for claiming 
CBI, please consult the person identified in the FOR FURTHER 
INFORMATION CONTACT section.
2. Tips for Preparing Your Comments
    When submitting comments, remember to:
    Identify the rulemaking by docket number and other identifying 
information (e.g., subject heading, Federal Register date and page 
number).
    Follow directions. The EPA may ask you to respond to specific 
questions or organize comments by referencing a CFR part or section 
number.
    Explain why you agree or disagree, and suggest alternatives and 
substitute language for your requested changes.
    Describe any assumptions and provide any technical information and/
or data that you used.
    If you estimate potential costs or burdens, explain how you arrived 
at your estimate in sufficient detail to allow us to reproduce your 
estimate.

II. Background and General Rationale

A. Background on Subpart W CBI Re-Proposal

    On October 30, 2009, the EPA published the Mandatory Reporting of

[[Page 11042]]

Greenhouse Gases Final Rule, 40 CFR part 98, for collecting information 
regarding greenhouse gases (GHGs) from a broad range of industry 
sectors (74 FR 56260). Under Part 98 and its subsequent amendments, 
certain facilities and suppliers above specified thresholds are 
required to report GHG information to the EPA annually. The data to be 
reported consist of GHG emission and supply information as well as 
other data, including information necessary to characterize, quantify, 
and verify the reported emissions and supplied quantities. In the 
preamble to Part 98, we stated, ``[t]hrough a notice and comment 
process, we will establish those data elements that are `emissions 
data' and therefore [under CAA section 114(c)] will not be afforded the 
protections of CBI. As part of that exercise and in response to 
requests provided in comments, we may identify classes of information 
that are not emissions data, and are CBI'' (74 FR 56287, October 30, 
2009).
    On July 7, 2010, the EPA proposed confidentiality determinations 
for data elements of all GHGRP subparts of Part 98 (75 FR 39094, 
hereinafter referred to as the ``July 7, 2010 CBI Proposal'').
    On May 26, 2011, the EPA published the final CBI determinations for 
the data elements in 34 Part 98 subparts, except for those data 
elements that were assigned to the ``Inputs to Emission Equations'' 
data category (76 FR 30782, hereinafter referred to as the ``Final CBI 
Rule''). That final rule did not include CBI determinations for subpart 
W for the reasons described above.
    The Final CBI Rule: (1) Created and finalized 22 data categories 
for part 98 data elements; (2) assigned data elements in 34 subparts to 
appropriate data categories; (3) for 16 data categories, issued 
category-based final CBI determinations for all data elements assigned 
to the category; and (4) for the other five data categories (excluding 
the inputs to emission equations category), the EPA determined that the 
data elements assigned to those categories were not ``emission data'' 
but made individual final CBI determination for those data elements. 
Finally, the EPA did not make final confidentiality determinations for 
the data elements assigned to the ``Inputs to Emission Equations'' data 
category.
    Subpart W reporting requirements were finalized on November 30, 
2010 (75 FR 74458), and the EPA has published two revisions to the 
final subpart W reporting requirements since that data. On September 
27, 2011, the EPA published the final rule: ``Mandatory Reporting of 
Greenhouse Gases: Petroleum and Natural Gas Systems: Revisions to Best 
Available Monitoring Method Provisions'' (76 FR 59533, hereinafter 
referred to as the ``BAMM Final Rule''), which revised certain BAMM 
extension request data elements and added a new data element in subpart 
W. Additionally, on December 23, 2011 the EPA published the final rule: 
``Mandatory Reporting of Greenhouse Gases: Technical Revisions to the 
Petroleum and Natural Gas Systems Category of the Greenhouse Gas 
Reporting'' (76 FR 80554, hereinafter referred to as the ``Technical 
Revisions Rule''), which provided clarification on existing 
requirements, increased flexibility for certain calculation methods, 
amended data reporting requirements, clarified terms and definitions, 
and made technical corrections. This action finalized the addition or 
revision of over 200 subpart W data elements. Today's re-proposal of 
confidentiality determinations for data elements addresses the subpart 
W data elements as finalized, including the revisions in the BAMM Final 
Rule and Technical Revisions Rule.

B. Background on Data Elements in the ``Inputs to Emission Equations'' 
Data Category

    The EPA received numerous public comments on the July 7, 2010 CBI 
Proposal. In particular, the EPA received comments that raised serious 
concerns regarding the public availability of data in the ``Inputs to 
Emission Equations'' category. In light of those comments, the EPA took 
three concurrent actions, which are as follows:
     Call for Information: Information on Inputs to Emission 
Equations under the Mandatory Reporting of Greenhouse Gases Rule, 75 FR 
81366 (December 27, 2010) (hereinafter referred to as the ``Call for 
Information'').
     Change to the Reporting Date for Certain Data Elements 
Required Under the Mandatory Reporting of Greenhouse Gases Rule; 
Proposed Rule, 75 FR 81350 (December 27, 2010) (hereinafter referred to 
as the ``Deferral Proposal'').
     Interim Final Regulation Deferring the Reporting Date for 
Certain Data Elements Required Under the Mandatory Reporting of 
Greenhouse Gases Rule, 75 FR 81338 (December 27, 2010) (hereinafter 
referred to as the ``Interim Final Rule'').
    On August 25, 2011, the EPA published the final ``Change to the 
Reporting Date for Certain Data Elements Required Under the Mandatory 
Reporting of Greenhouse Gases Rule'' (76 FR 53057, hereinafter referred 
to as the ``Final Deferral''). In that action, the EPA deferred the 
deadline for reporting some ``Inputs to Emission Equations'' data 
elements to March 31, 2013, and others to March 31, 2015. Data elements 
with the March 31, 2013 reporting deadline are identified in Table A-6 
of subpart A and those with the March 31, 2015 reporting deadline are 
identified in Table A-7 to subpart A. For subpart W, the EPA deferred 
the reporting of all data elements classified as ``Inputs to Emission 
Equations'' as of the publication of the Final Deferral until March 31, 
2015.
    Currently, Table A-7 does not reflect the changes or additions to 
inputs to equations made in the Technical Revisions Rule. The agency is 
now addressing this in today's action.

III. Re-Proposal of CBI Determinations for Subpart W

A. Overview

    We propose to assign each of the data elements in subpart W, a 
direct emitter subpart, to one of eleven direct emitter data categories 
created in the Final CBI Rule. As noted previously, for 8 of the 11 
direct emitter categories, the EPA has made categorical confidentiality 
determinations, finalized in the Final CBI Rule. For these eight 
categories, the EPA is proposing to apply the categorical 
confidentiality determinations (made in the Final CBI Rule) to the 
subpart W reporting elements assigned to each of these categories.
    In the Final CBI Rule, for 2 of the 11 data categories, the EPA did 
not make categorical confidentiality determinations, but rather made 
confidentiality determinations on an element by element basis. We are 
therefore following the same approach in this action for the subpart W 
reporting elements assigned to these 2 categories.
    Lastly, in the Final CBI Rule, for the final data category, 
``Inputs to Emissions Equations''; the EPA did not make a final 
confidentiality determination and indicated that this issue would be 
addressed in a future action. Please note that in the Final Deferral, 
the EPA already assigned certain subpart W data elements to the 
``Inputs to Emission Equations'' data category. However, since then, 10 
data elements were added to subpart W after the Final Deferral was 
promulgated. The EPA is proposing to assign these 10 new data elements 
to the ``Inputs to Emission Equations'' data category, as well as 
proposing to defer the reporting of these inputs until 2015. Please see 
the memorandum entitled ``Proposed Data Category Assignments for 
Subpart W'' in Docket ID No. EPA-

[[Page 11043]]

HQ-OAR-2011-0028 for a listing of the data elements that the EPA is 
proposing to assign to this data category. Note that we are not 
proposing confidentiality determinations at this time for any subpart W 
data elements assigned to the ``Inputs to Emissions Equations'' data 
category and plan to propose confidentiality determinations for 
elements in this data category in a later action. Please see the 
following Web site for further information on this topic: http://www.epa.gov/climatechange/emissions/CBI.html.
    Table 2 of this preamble summarizes the confidentiality 
determinations that were made in the Final CBI Rule for the following 
direct emitter data categories created in that notice. Please note that 
the ``Inputs to Emission Equations'' data category is excluded, as 
final determinations for that category have not yet been made.

\a\ Under CAA section 114(c), ``emission data'' are not entitled to confidential treatment. The term ``emission
  data'' is defined at 40 CFR 2.301(a)(2)(i).
\b\ Section 114(c) of the CAA affords confidential treatment to data (except emission data) that are considered
  CBI.
\c\ In the Final CBI Rule, this data category contains both data elements determined to be CBI and those
  determined not to be CBI.

    We are requesting comment on several aspects of this proposal. 
First, we seek comment on the proposed data category assignment for 
each of these data elements. If you believe that the EPA has improperly 
assigned certain data elements in this subpart to one of the data 
categories, please provide specific comments identifying which data 
elements may be mis-assigned along with a detailed explanation of why 
you believe them to be incorrectly assigned and in which data category 
you believe they best would belong.
    Second, we seek comment on our proposal to apply the categorical 
confidentiality determinations (made in the Final CBI Rule for eight 
direct emitter data categories) to the data elements in subpart W that 
are assigned to those categories.
    Third, for those data elements assigned to the two direct emitter 
data categories without categorical CBI determinations, we seek comment 
on the individual confidentiality determinations we are proposing for 
these data elements. If you comment on this issue, please provide 
specific comment along with detailed rationale and supporting 
information on whether such data element does or does not qualify as 
CBI.
    Because this is a re-proposal, the EPA is not responding to 
previous comments submitted on the July 7, 2010 CBI Proposal relative 
to the data elements in this subpart. Although the EPA considered those 
comments when developing this re-proposal, we encourage you to resubmit 
all relevant comments to ensure their consideration by the EPA in this 
rulemaking. In resubmitting previous comments, please make any 
necessary changes to clarify that you are addressing the re-proposal 
and add details as requested in Section III.D of this preamble.

B. Approach To Making Confidentiality Determinations

    For a direct emitter subpart such as subpart W, the EPA proposes to 
assign each data element to one of 11 direct emitter data categories. 
As noted previously, the EPA made categorical confidentiality 
determinations for eight direct emitter data categories, and the EPA 
proposes to apply those final determinations to the subpart W data 
elements assigned to those categories in this rulemaking. For the data 
elements in the two non-inputs direct emitter data categories that do 
not have categorical confidentiality determinations, we are proposing 
to make confidentiality determinations on an individual data element 
basis.\1\
---------------------------------------------------------------------------

    \1\ As mentioned above, EPA determined that data elements in 
these two categories are not ``emission data'' under CAA section 
114(c) and 40 CFR 2.301(a)(2)(i) for purposes of determining the GHG 
emissions to be reported under Part 98. That determination applies 
to data elements in subpart W assigned to those categories through 
this rulemaking.
---------------------------------------------------------------------------

    The following two direct emitter data categories do not have 
category-based CBI determinations: ``Unit/Process `Static' 
Characteristics That are Not Inputs to Emission Equations'' and ``Unit/
Process Operating Characteristics That are Not Inputs to Emission 
Equations.'' For these two categories, the EPA evaluated the individual 
data elements assigned to these categories to determine whether 
individual data elements qualify as CBI. In the sections below, the EPA 
explains the data elements in these two categories and states the 
reasons for proposing to determine that each does or does not qualify 
as CBI under CAA section 114(c). The EPA is specifically soliciting 
comments on the CBI proposals for data elements in these two data 
categories. In section III.C of this preamble, the data elements in 
these two data categories are listed individually by data category 
along with the proposed confidentiality determination. The data 
elements along with their proposed confidentiality determinations are 
also listed in the memorandum entitled ``Proposed Data Category 
Assignments for Subpart W'' in

[[Page 11044]]

Docket ID No. EPA-HQ-OAR-2011-0028.

C. Proposed Confidentiality Determinations for Individual Data Elements 
in Two Data Categories

    The EPA is proposing to assign 28 subpart W data elements to the 
``Unit/Process `Static' Characteristics that Are Not Inputs to Emission 
Equations'' data category because they are basic characteristics of 
units, equipment, abatement devices, and other facility-specific 
characteristics that do not vary with time or with the operations of 
the process (and are not inputs to emission equations). These 28 data 
elements are proposed as non-CBI with the rationales shown in Table 3 
of this preamble as follows:

   Table 3--Data Elements Proposed To Be Assigned to the ``Unit/Process `Static' Characteristics That Are Not
                                  Inputs to Emission Equations'' Data Category

    The EPA is proposing to assign 38 subpart W data elements to the 
``Unit/process Operating Characteristics that Are Not Inputs to 
Emission Equations'' data category, because they are characteristics of 
equipment, such as wells and plunger lifts, abatement devices, and 
other facility-specific characteristics that vary over time with 
changes in operations and processes (and are not inputs to emission 
equations). Some of these elements are part of extension requests for 
the use of BAMM and generally relate to the reasons for a request and 
expected dates of compliance with regular reporting requirements. The 
remaining data elements are part of the annual GHG report for 40 CFR 
part 98, subpart W. All of the 38 data elements are listed below. Of 
the 38 data elements, elements 1 thru 37 are proposed as non-CBI, while 
data element 38 is proposed to be CBI, as explained in Table 4 of this 
preamble:

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

[[Page 11058]]

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

    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,

[[Page 11059]]

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

[[Page 11060]]

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.
