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.

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).
-
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:

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.

Background and General Rationale

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, ``through 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.
-
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.

Re-Proposal of CBI Determinations for Subpart W
-
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.

\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.

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

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:

Inputs to Emission Equations'' Data Category

CO2 injected, because the pump capacity is
proportional to the volume of CO2 that the
pump is pumping (i.e., the volume of CO2e
reported). Therefore, if the volume of CO2
that was pumped is known, then the pump's
capacity can be estimated to be between 150 to
200 percent greater than the reported volume,
to handle fluctuations in CO2 loads. The
quantity of CO2 injected can be determined
from Underground Injection Control (UIC)
permits, which are issued for each injection
well by the EPA or by states that have primary
enforcement authority for permitting injection
wells. Information related to UIC permits is
reported to the EPA or states at least
annually and made available to the public

from the public. Finally, knowing the pump
capacity does not result in any competitive
disadvantage to the reporter, because the
injection volume of the pump, which is related

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:

be non-confidential, because the disclosure of
this data likely would not cause substantial
competitive harm. The data is reported at a
basin level as opposed to a field or sub-basin
level, which is at a much greater level of
granularity. Furthermore, reporting the number
of wells tested in a basin for a given year
does not provide any insight on exactly which
wells within that basin were tested, thereby
diminishing the sensitivity associated with

Disclosure of the average gas to oil ratio of

information on the gas to oil ratio for wells
can be determined through publicly available
information through many state agencies (e.g.,
the Railroad Commission of Texas lists the gas

cause substantial harm, because reporters are
reporting an average for all of the wells
tested within a basin rather than reporting
for the number of data days of well testing
for individual wells. Furthermore, the number

Also, this data element is reported as an
average ratio for the sub-basin and is not
reported on a per well basis, further
diminishing sensitivity associated with
disclosure. The EPA is proposing that this
data element is not confidential; and that it
will be considered non-CBI.

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.

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 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.

Statutory and Executive Order Reviews
-
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).
-
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.
-
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.

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).

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).
-
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.
-
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.
-
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 .

-
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.

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.
