RIN 2060-AR53


2012 Technical Corrections, Clarifying and Other Amendments to 
the Greenhouse Gas Reporting Rule, and Proposed Confidentiality 
Determinations for Certain Data Elements of the Fluorinated Gas Source 
Category

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA is proposing to amend specific provisions of the 
Greenhouse Gas Reporting Rule to provide greater clarity and 
flexibility to facilities subject to reporting emissions from certain 
source categories. These source categories will report greenhouse gas 
(GHG) data for the first time in September of 2012. The proposed 
changes are not expected to significantly change the overall 
calculation and monitoring requirements of the Greenhouse Gas Reporting 
Rule or add additional requirements for reporters, but are expected to 
correct errors and clarify existing requirements in order to facilitate 
accurate and timely reporting. The EPA is also proposing 
confidentiality determinations for four new data elements for the 
fluorinated gas production source category of the Greenhouse Gas 
Reporting Rule. Lastly, we are proposing an amendment to Table A-7 of 
the general provisions to add a data element used as an input to an 
emission equation in the fluorinated gas production source category.

DATES: Comments. Comments must be received on or before June 20, 2012.
    Public Hearing. The EPA does not plan to conduct a public hearing 
unless requested. To request a hearing, please contact the person

I. Background

A. How is this preamble organized?

    The first section of this preamble contains the basic background 
information about the origin of these proposed rule amendments and 
request for public comment. This section also discusses the EPA's use 
of our legal authority under the Clean Air Act to collect data under 
the Mandatory Reporting of Greenhouse Gases Reporting Rule, hereinafter 
referred to as the ``GHG Reporting Rule.''
    The second section of this preamble describes in detail the changes 
that are being proposed to correct technical errors, to provide 
clarification, or to address implementation issues identified by the 
EPA and others. This section also presents the EPA's rationale for the 
proposed changes and identifies issues on which the EPA is particularly 
interested in receiving public comments. This section also includes 
proposed confidentiality determinations for four new data elements for 
the fluorinated gas production source category of the Greenhouse Gas 
Reporting Rule.
    Finally, the last (third) section of the preamble discusses the 
various statutory and executive order requirements applicable to this 
proposed rulemaking.

B. Background on This Action

    The 2009 final GHG Reporting Rule was signed by EPA Administrator 
Lisa Jackson on September 22, 2009 and published in the Federal 
Register on October 30, 2009 (74 FR 56260, hereafter referred to as the 
``2009 final rule'' or ``Part 98''). The 2009 final rule, which became 
effective on December 29, 2009, requires reporting of GHGs from various 
facilities and suppliers, consistent with the 2008 Consolidated 
Appropriations Act.\1\ Subsequent notices were published in 2010 
finalizing the requirements for subpart TT (75 FR 39736, July 12, 
2010), subpart W (75 FR 74458, November 30, 2010), and subpart L (75 FR 
74774, December 1, 2010).
---------------------------------------------------------------------------

    \1\ Consolidated Appropriations Act, 2008, Public Law 110-161, 
121 Stat. 1844, 2128.
---------------------------------------------------------------------------

    Following the promulgation of these subparts, the EPA finalized 
four technical corrections and clarifying amendments to these and other 
subparts under the Greenhouse Gas Reporting Program (GHGRP) (75 FR 
66434, October 28, 2010; 75 FR 79092, December 17, 2010; 76 FR 73866, 
November 29, 2011; 76 FR 80554, December 23, 2011). The corrections and 
amendments within those four actions did not change the basic 
requirements of the rule, but were intended to improve clarity and 
ensure consistency across the calculation, monitoring, and data 
reporting requirements. Similarly, the corrections, clarifying and 
other amendments in this action are intended to provide greater clarity 
and flexibility to facilities subject to reporting in 2012.
    On January 10, 2012 (77 FR 1434), EPA proposed confidentiality 
determinations for data elements (excluding those in the inputs to 
equation category) in 8 subparts of part 98, including subpart L. This 
proposed amendment includes adding 4 new data elements to subpart L. In 
conjunction with this addition, we are proposing confidentiality 
determinations for the new data elements in the proposed amendment to 
subpart L.

C. Legal Authority

    The EPA is proposing these 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 
require the information proposed to be gathered by this rule 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 rule (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 who the

[[Page 29938]]

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. For 
further information about the EPA's legal authority, see the preambles 
to the 2009 proposed and final rules and EPA's Response to Comments, 
Volume 9.
    In addition, EPA is proposing confidentiality determinations for 
four proposed data elements in subpart L, under its authorities 
provided in sections 114, 301 and 307 of the CAA. As mentioned above, 
CAA section 114 provides EPA authority to obtain the information in 
part 98, including those in subpart L. Section 114(c) requires that EPA 
make publicly available information obtained under section 114 except 
for information (excluding emission data) that qualify for confidential 
treatment.
    The Administrator has determined that this action (proposed 
amendment and confidentiality determination) is subject to the 
provisions of section 307(d) of the CAA.

D. How would these amendments apply to 2012 reports?

    The EPA is proposing technical clarifications and amendments to 40 
CFR part 98, subparts A, L, W, and TT. The EPA is planning to address 
any comments on these proposed amendments and publish final amendments 
before September 28, 2012. Therefore, reporters would be expected to 
calculate emissions and other relevant data for the reports that are 
submitted by September 28, 2012 using 40 CFR part 98 as amended by this 
proposed action. We have determined that it is feasible for the sources 
to implement these changes for the 2011 reporting year because the 
revisions are primarily technical corrections that provide 
clarifications regarding the existing regulatory requirements, or 
reduce the amount of information that is required to be reported. The 
proposed amendments do not change the type of information that must be 
collected, and do not materially affect how emissions are calculated.
    In the case of 40 CFR part 98, subpart A (subpart A), the proposed 
amendment is merely a harmonizing change to a technical correction 
finalized in February 2012 (see 77 FR 10373). That final amendment 
required reporters to calculate emissions of certain additional 
fluorinated heat transfer fluids under subpart I; however, the EPA 
inadvertently did not amend the corresponding requirement to include 
those calculated emissions in the annual GHG report. In this action, we 
are proposing to include these emissions from heat transfer fluids in 
the facility level totals reported to the EPA in the annual GHG report.
    In the case of 40 CFR part 98, subpart L (subpart L), the EPA is 
proposing that facilities subject to subpart L report greenhouse gas 
emissions in a less detailed manner for Reporting Years 2011 and 2012. 
This proposed amendment is a temporary change (i.e., for years 2011 and 
2012 only) to allow the EPA time to fully evaluate concerns recently 
raised by stakeholders that reporting, and subsequent EPA release, of 
certain emission data would reveal trade secrets.
    In the case of 40 CFR part 98, subpart W (subpart W), the EPA 
concludes that these proposed amendments are all technical corrections 
that, while important to make to allow reporters to calculate emissions 
accurately, do not materially affect the actions facilities would have 
already undertaken to comply with the rule. For example, in this 
action, EPA is proposing a correction to the emission factors in Table 
W-1A of subpart W for the onshore petroleum and natural gas production 
segment. In the December 23, 2011 final rule (76 FR 80554, December 23, 
2011, referred to hereinafter as the ``December 2011 final rule''), the 
EPA revised several of the emission factors in this table, along with 
the emission factors in other tables in subpart W to reflect a 
consistent standard temperature and pressure. In the process of 
converting specific emission factors within Table W-1A of subpart W an 
omission occurred that we are proposing to correct in this action. As 
stated previously, a proposed change such as this would not materially 
affect the actions a facility would undertake to comply with the rule.
    In the case of 40 CFR part 98, subpart TT (subpart TT), this 
proposal excludes some facilities from the reporting requirements and 
thereby further reduces the reporting under the GHG Reporting Rule. 
These excluded facilities are not expected to emit GHGs since they only 
receive inert wastes that do not generate methane.
    For additional background information regarding some of these 
amendments, please refer to the Technical Support Document for the 2012 
Technical Corrections, Clarifying and Other Amendments to Certain 
Provisions of the Greenhouse Gas Reporting Rule proposal available in 
the docket for this rulemaking (EPA-HQ-OAR-2011-0147).
    The EPA generally seeks comment on the EPA's conclusion that it 
would be appropriate to implement these proposed amendments and 
incorporate the requirements for the data that must be reported to the 
EPA by September 2012. Further, we seek comment on whether there are 
specific proposed changes for which this timeline may not be feasible 
or appropriate. We request that commenters provide specific examples of 
how the proposed implementation schedule would or would not be 
feasible.

E. How would these amendments affect confidentiality determinations?

    The proposed amendments do not affect the confidentiality 
determinations for subpart A data elements finalized in the Final CBI 
rule,\2\ (hereinafter referred to as the ``final CBI rule''), the 
proposed determinations for subpart W \3\ and subparts L and TT,\4\ or 
the proposed or final deferral rule(s) extending the reporting 
deadlines for the data elements in these subparts that are as assigned 
to the inputs to emission equations data category.\5\

    \2\ See 75 FR 30782, May 26, 2011.
    \3\ See 77 FR 11039, February 24, 2012.

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

    In this notice, we are proposing confidentiality determinations for 
proposed new subpart L data elements. The proposed confidentiality 
determinations for these new data elements together with our rationale 
are discussed in detail in Section II.D.3 of this preamble.
    There are no proposed determinations for subparts A, W, and TT, 
since the proposed amendments to those subparts do not include any 
proposed new data elements. The proposed amendments would delete an 
existing subpart W data element and make only minor clarifications to 
the existing reporting requirements in subpart W. For the Subpart A 
proposed amendments, we are not proposing any confidentiality 
determinations because the data element being added is a subset of 
another data element in subpart I for which we've already proposed a 
CBI determination. This is explained in further detail in Section 
II.A.3 of this preamble. There are no proposed amendments to the 
reporting requirements for subpart TT.

II. Technical Corrections, Clarifying and Other Amendments

    The EPA has identified minor corrections, clarifying and other 
amendments that we are now proposing in this action. We have also 
identified certain rule provisions that we are

[[Page 29939]]

proposing to amend to provide greater clarity. The amendments we are 
now proposing include the following types of changes:
     Changes to correct cross references within and between 
subparts.
     Amendments to certain equations to better reflect actual 
operating conditions.
     Corrections to terms and definitions in certain equations.
     Corrections to data reporting requirements so that they 
more closely conform to the information used to perform emission 
calculations.
     Amendment to Table A-7 to subpart A to add a Subpart L 
data element used as an input to an emission equation that was 
inadvertently omitted in the final deferral rule.
     Other amendments related to certain issues identified as a 
result of working with the affected sources during rule implementation 
and outreach.
    We are seeking public comment only on the issues specifically 
identified in this proposed rule for the identified subparts. We will 
not consider, through this notice and comment process, comments that 
are outside the scope of this proposed rule.

A. Subpart A--General Provisions

1. Background
    In today's rule, we are proposing a few minor amendments to the 
general reporting requirements of 40 CFR 98.3(c)(4) of subpart A. These 
changes relate to reporters that would be reporting under the 
electronics manufacturing source category (40 CFR part 98, subpart I; 
hereinafter referred to as ``subpart I''). We are also proposing an 
amendment to Table A-7 to subpart A to add a Subpart L data element 
used as an input to an emission equation that was inadvertently omitted 
in the final deferral rule.
    For subpart I, the proposed change clarifies the GHGs that should 
be reported in the annual GHG report (40 CFR 98.3(C)(4)). This proposed 
change follows the amendments to reporting requirements for heat 
transfer fluids (fluorinated HTFs) that were published on February 22, 
2012 (77 FR 10373). In that rule, the EPA amended the definition of 
fluorinated HTFs to specify that the lower vapor pressure limit clause 
in the subpart A definition of fluorinated GHG did not apply to 
fluorinated HTFs in subpart I beginning in reporting year 2012 (40 CFR 
98.98).
2. Proposed Amendments
    Section 98.3(c)(4) of subpart A specifies the types of data and 
format for reporting emissions in the annual GHG reports (e.g., annual 
emissions from each source category by GHG). Without the proposed 
change to conform the subpart I requirements for fluorinated HTFs with 
subpart A, reporters are required to calculate emissions of fluorinated 
HTFs under subpart I but report only a subset of them in their annual 
report totals under subpart A. The proposed amendment to subpart A 
specifies that facilities subject to subpart I must include all 
fluorinated HTFs in the computation of CO2e that is required 
by 40 CFR 98.3(c)(4)(i). Facilities must report each fluorinated HTF 
that is also a fluorinated GHG under 40 CFR 98.3(c)(4)(iii)(E) and each 
fluorinated HTF that is not a fluorinated GHG in the newly proposed 
data element, 40 CFR 98.3(c)(4)(iii)(F). Today's proposed change is a 
harmonizing modification to clarify how facilities subject to subpart I 
would report the emissions from fluorinated heat transfer fluids, as 
required by the February 22, 2012 amendments to subpart I. The EPA 
determined that this change would simplify reporting for facilities and 
reduce burden by amending subpart A to be consistent with the 
requirements in subpart I.
    The EPA is proposing to make this change effective for reporting 
year 2012. Given that facilities are already required to calculate 
emissions of fluorinated HTFs under subpart I, reporters will already 
have the necessary data to comply with the proposed amendments.
    Table A-7 to subpart A of Part 98 lists the inputs to emission 
equations whose reporting deadlines are currently deferred until March 
31, 2015. In the final deferral, the data element, ``the mass of each 
fluorine-containing product produced by the process'' (40 CFR 
98.126(b)(7)) was inadvertently omitted from Table A-7 of subpart A. 
This data element is an input to an equation because it is used in 
Equation L-6. Thus, we are proposing to amend Table A-7 to subpart A to 
include this input and hence, defer its reporting deadline until March 
31, 2015.
3. Overview and Approach to Proposed CBI Determinations
    The proposed changes to subpart A do not affect the proposed 
confidentiality determinations for subpart A or I data elements or the 
proposed deferral of the deadline for reporting inputs to emission 
equations (February 22, 2012, 77 FR 10434; Mandatory Reporting of 
Greenhouse Gases Rule: Confidentiality Determinations and Best 
Available Monitoring Methods Provisions, hereinafter referred to as the 
``February 22, 2012 CBI rule'').
    As discussed in Section II.A.2 of this preamble, the EPA is 
proposing to add a data element in Subpart A (98.3(c)(4)(iii)(F)). This 
additional data element is a harmonizing change that makes the subpart 
A requirements consistent with the recently finalized February 22, 2012 
subpart I amendments. To that end, the information that would be 
reported under the proposed new data element in subpart A is a subset 
of the information to be reported under the data element 98.96(c)(4), 
which the EPA proposed to be non-confidential by assigning it to the 
``Emissions'' category in a recent action.\6\ Since the information 
proposed under Subpart A in today's action is a subset of the 
information to be reported under 98.96(c)(4), the confidentiality 
determination proposed for that subpart I data element applies to the 
subpart A data element proposed in this action. As a result, we are not 
proposing a confidentiality determination for the new subpart A data 
element in this action.

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

B. Subpart TT--Industrial Waste Landfills

1. Background
    In this action we are proposing one correction to the provisions of 
subpart TT to exclude certain facilities that only receive inert waste 
from reporting requirements under the GHG Reporting Rule. This proposed 
amendment would ensure that landfills that are not expected to emit 
GHGs are excluded from reporting requirements under this subpart.
2. Proposed Amendment
    We are proposing one technical amendment to subpart TT to address 
questions received about applicability of the subpart to industrial 
waste landfills that receive only inert wastes. In subpart TT, the 
volatile solids concentration is used as a surrogate for determining 
degradable organic carbon (DOC) content of a waste material [40 CFR 
98.464(b)(4)(ii)]. In 40 CFR 98.460(c)(xii), the EPA provides an 
exclusion for those facilities that receive inert waste materials 
``with a volatile solids concentration of 0.5 weight percent (on a dry 
basis) or less.'' However, some landfill owners or operators test their 
waste stream to determine directly waste-specific degradable organic 
content. These tests, when performed as described in 40 CFR 
98.464(b)(4)(i)(A) of the rule, can provide a more accurate DOC value 
than calculating organic content from volatile

[[Page 29940]]

solids. Therefore, to ease reporting burden on those facilities that 
receive inert waste but calculate DOC directly, we propose to add a 
direct DOC value exclusion as 40 CFR 98.460(c)(2)(xiii). This exclusion 
would be provided in weight percent on a wet basis because this is 
consistent with the units for DOC.
3. Overview and Approach to Proposed CBI Determinations
    This proposed amendment to subpart TT is not expected to affect the 
proposed confidentiality determinations for subpart TT data elements or 
the proposed deferral of the deadline for reporting of inputs to 
emission equations (January 10, 2012, 77 FR 1434; Proposed 
Confidentiality Determinations for Data Elements Under the Mandatory 
Reporting of Greenhouse Gases Rule and Amendments to Table A-6 to 
Subpart A of Part 98, of the Greenhouse Gas Reporting Rule, hereinafter 
referred to as the January 10, 2012 CBI rule.)

C. Subpart W--Petroleum and Natural Gas Systems

1. Background
    In this action, the EPA is proposing minor corrections and 
clarifying amendments to certain provisions to assist facilities with 
implementing existing rule requirements. We are proposing technical 
corrections to provisions in subpart W for calculating and reporting 
greenhouse gas emissions, as well as several emission factors in 
associated tables. Since publication of subpart W in November 2010, the 
EPA amended subpart W on December 23, 2011, (76 FR 80554). That notice 
included technical corrections and clarifications designed to increase 
flexibility, provide needed clarification regarding applicability, and 
to address specific errors in equations and citations. This proposal 
complements that action and is not intended to duplicate or replace the 
amendments published on December 23, 2011.
    Many of the corrections in the December 23, 2011 action were the 
result of internal review by the EPA, as in the case of the correction 
to the calculation methodology for estimating emissions from gas well 
venting during completions and workovers using hydraulic fracturing. 
Onshore petroleum and natural gas facilities subject to subpart W are 
required to report emissions resulting from this emission source using 
one of three methods in the December 23, 2011 rule. The first method 
relies on installation of a recording flow meter on the vent line 
(upstream of a flare or vent if used) to measure the flowback rate for 
representative wells in each gas producing sub-basin category and well 
type combination. The second method is based on engineering equations 
to calculate the well flowback during well completions and workovers 
from hydraulic fracturing. The last method applies to facilities that 
are already measuring the flowback volumes during gas well completions 
or workovers within a given sub-basin and well type combination.
    Following the EPA's review of this emission source, and method two 
in particular, we determined that correction was needed to Equations W-
11A and W-11B to convert the resultant flow rate (parameter FR) into 
standard conditions instead of the resultant actual conditions as 
written. Without this conversion, the calculated flow volumes in 
Equations W-11A and W-11B would incorrectly result in actual conditions 
instead of standard conditions, which is necessary for input into 
Equations W-12 and W-10A. In this action, the EPA is proposing to 
include a correction to convert the flow rate determined in Equation W-
11A and W-11B to standard conditions through the use of Equation W-33.
2. Proposed Technical Corrections
    EPA is proposing several technical corrections and amendments to 
subpart W to correct equations and otherwise clarify provisions in the 
rule to ensure consistency across the calculation, monitoring, and 
reporting requirements in subpart W and thereby facilitate reporting.
    This section describes the EPA's proposed corrections for subpart 
W.
    Calculating Greenhouse Gas Emissions. The EPA is proposing several 
clarifications, corrections, and amendments throughout 40 CFR 98.233. 
These proposed changes are intended to clarify terms, correct 
references, and remove extraneous terms.
    Dehydrator Vents. The EPA is proposing to amend Equation W-6 in 40 
CFR 98.233(e)(5) by removing a factor of 1000 from the denominator so 
that the calculated emissions will result in standard cubic feet rather 
than thousand standard cubic feet.
    Well Venting for Liquids Unloading. The EPA is proposing to provide 
reporters with the option to take and use more than the prescribed 
number of sample measurements per unique well tubing diameter and 
pressure group combination per sub-basin. The EPA notes that this would 
not change the burden to reporters, and still only would require that 
one sample per unique well tubing diameter and pressure group 
combination be taken, but would allow reporters to account for any 
additional samples that they may have already taken.
    The EPA is proposing to amend Equation W-7 in 40 CFR 98.233(f)(1) 
by changing the parameter ``FRp'' to ``FR'' in both Equation 
W-7 and in the definition to avoid confusion. As previously written, 
the equation could be interpreted to imply that the flow rate should be 
measured for all wells, as ``p'' refers to all wells in a pressure 
group and tubing group combination; rather, the intention of the 
equation is to calculate the flow rate for at least one well in each 
tubing and pressure group combination within a sub-basin. Removing the 
subscript ``p'' from the parameter and revising the parameter 
definition accordingly clarifies that the measurement is not for all 
wells. Also in Equation W-7, the EPA is proposing to amend the 
parameter Tp and its definition to clarify that it refers to 
the cumulative amount of time in hours for venting of each well as 
opposed to the time for the well(s) that were measured.
    The EPA is proposing to update Equation W-8 in 40 CFR 98.233(f)(2) 
by revising the definition of parameter SPp to clarify that 
the reporter must take a ratio of casing to tubing pressure. The EPA is 
further updating Equation W-8 and also Equation W-9 in 40 CFR 
98.233(f)(3) by replacing the subscript ``q'' with ``p'' in parameter 
SFR to match the definition of parameter SFRp. Finally, for 
Equations W-8 and W-9, the EPA is clarifying that the terms Vp and 
HRp,q are to be monitored per unloading event.
    Gas Well Venting During Completions and Workovers from Hydraulic 
Fracturing. The EPA reviewed Equation W-11A, which calculates a flow 
rate for subsonic flow, and Equation W-11B, which calculates a flow 
rate for sonic flow. These equations are intended to calculate flow of 
gas following hydraulic fracturing of gas wells through a choke at the 
wellhead. The EPA determined that the equations as presented in the 
final rule are correct. However, it may not be clear in the December 
2011 final rule that the output from Equations W-11A and W-11B are at 
actual conditions, i.e., subsonic and sonic flow conditions and that a 
conversion of the results from Equation W-11A and W-11B to standard 
conditions is required prior to use in Equation W-12. Omitting the step 
of converting actual to standard conditions results in a lower flowrate 
output from Equation W-11A or Equation W-11B, which corresponds to a 
lower emissions calculation in Equation W-10A. In this

[[Page 29941]]

proposed rule, EPA proposes to add a reference to 40 CFR 98.233(t) in 
the parameter definition FRs,p to convert FRa to 
standard conditions. Furthermore, to eliminate this potential ambiguity 
and make the equations more explicit, the EPA is proposing to insert 
the word ``actual'' in the definition of flow rate, FR, and also add a 
subscript ``a.'' Finally, EPA proposes to clarify the definition of 
orifice cross sectional area, ``A'' to state ``Cross sectional open 
area of the restriction orifice (m2).''
    The EPA is proposing to clarify that the flow volume variable 
FVs,p in Equation W-10B is at standard cubic feet, which is 
a volume unit as opposed to the standard cubic feet per hour flow rate 
unit in the December 2011 final rule. Although the engineering 
equations in subpart W more commonly use flow rates as units of 
measurement, the use of flow volumes in equation W-10B is similar to 
the use of flow volume in 40 CFR 98.233(n), which includes provisions 
for reporters to calculate their flow volumes in standard cubic feet as 
opposed to a cubic feet per hour flow rate value.
    Finally, the EPA is proposing to provide reporters with the option 
to take and use more than the prescribed number of sample measurements 
per sub-basin and well type (horizontal or vertical). As described 
above for a similar proposed amendment for well venting for liquids 
unloading, the EPA notes that this would not change the burden to 
reporters, but would allow reporters to account for any additional 
samples that they may have already taken.
    Gas Well Venting During Completions and Workovers Without Hydraulic 
Fracturing. The EPA is proposing amendments to clarify that the output 
of Equation W-13 is a sum of emissions from all completions and 
workovers without hydraulic fracturing within a sub-basin.
    Blowdown Vent Stacks. The EPA is proposing to revise the 
nomenclature of two terms in Equations W-14A and W-14B. First, the EPA 
is revising the parameter ``Es,n'' in the parameter 
description to match the term in the Equation W-14B. Second, the EPA is 
revising the term ``Ta'' to ``Ta,p'' in Equation 
W-14B to clarify the intent of the equation, which allows the reporter 
to input the temperature in actual conditions for each blowdown event 
``p.''
    Onshore Production Storage Tanks. The EPA is proposing to revise 40 
CFR 98.233(j)(5) to clarify that the term ``throughput'' refers to 
``average daily throughput of oil'' consistent with similar changes 
made elsewhere in 40 CFR 98.233(j) during the December 23, 2011 
technical corrections final rule. The EPA is also proposing to revise 
the definition of ``Count'' in Equation W-15 of 40 CFR 98.233(j)(5) to 
clarify that the reporters are to only count the separators or wells 
that feed oil directly to the storage tank. The count should not 
include separators that feed oil to other separators. The EPA is also 
proposing to revise the parameter definition of ``1000'' to accurately 
describe the conversion occurring through this parameter.
    Well Testing Venting and Flaring. The EPA is proposing to revise 
the definition of ``PR'' in Equation W-17B of 40 CFR 98.233(l)(3) to 
clarify that the production rate is in actual and not standard 
conditions.
    Flare Stack Emissions. The EPA is proposing to remove and reserve 
40 CFR 98.233(n)(7) to harmonize the language with the reporting 
requirements in 40 CFR 98.236, which requires emissions to be reported 
separately for combusted CO2, uncombusted CO2, 
and uncombusted CH4. This deletion would remove an undesired 
calculation.
    Centrifugal and Reciprocating Compressors. The EPA is proposing to 
make technical corrections to Equations W-23, W-24, W-27, and W-28 to 
provide the proper notation for the summations in those equations so 
that owners and operators may correctly calculate GHG emissions from 
centrifugal and reciprocating compressors. Although EPA recognizes that 
additional clarifications to the definitions in the parameters to these 
equations could be helpful to owners and operators, the EPA has not 
proposed any substantive changes in this action. This is because, 
following the publication of subpart W in the Federal Register in 2010, 
several industry groups requested reconsideration of several provisions 
in the final rule, including the reciprocating and centrifugal 
compressor monitoring requirements. At present, we are merely making 
technical corrections to the existing equations in the rule, and are 
not granting reconsideration of the compressor requirements or any 
other issues raised in those petitions for reconsideration in this 
action. We will consider the compressor monitoring requirements at a 
later time.
    Finally, the EPA is proposing to revise the definition of parameter 
EFi in Equation W-25 in 40 CFR 98.233(o)(7) by deleting the 
term ``thousand'' to eliminate an unnecessary unit conversion.
    Population Count and Emission Factors. We are also proposing to 
amend an incorrect reference in 40 CFR 98.233(r)(2) to ``Table W-1A'' 
to Subpart A of Part 98 instead of ``Table 1-A.''
    Finally, in 40 CFR 98.233(r)(6)(ii), we are proposing to revise the 
term ``meter or regulator'' and replace it with ``meter/regulator,'' 
for consistency with the term prescribed in the definition in 40 CFR 
98.238.
    Volumetric emissions. The EPA is proposing to revise 40 CFR 
98.233(t) to clarify that reporters do not need to alter their 
calculation results to standard conditions if the results already 
reflect standard conditions.
    GHG mass emissions. The EPA is proposing to revise the definition 
of parameter ``[rho]i'' in Equation W-36 to amend the 
density value of CH4 to be 0.0192 kg/ft3 in 
Equation W-36. The current density value of 0.04220 is the density of 
CH4 in lb/ft3. In the required units of kg/
ft3, the density value for CH4 should be 0.0192 
kg/ft3.
    Onshore Production and Distribution Combustion Emissions. The EPA 
is proposing to replace the parameter ``ECO2'' with 
``Ea,CO2'' in the parameter definition for Equation W-39A in 
40 CFR 98.233(z)(2)(iii) to match the parameters in the equation. 
Finally, the EPA is proposing to revise the definition of ``HHV'' in 40 
CFR 98.233(z)(2)(vi) to reflect the correct term represented by the 
acronym.
    Data Reporting Requirements. The EPA is proposing amendments to 
specific provisions within 40 CFR 98.236. These changes are intended to 
clarify terms, correct references, and remove extraneous terms.
    First, the EPA is proposing to amend 40 CFR 98.236(c)(5)(ii)(D) to 
clarify that the average internal casing diameter of all wells, as 
opposed to each well, must be reported.
    Second, we propose to amend 40 CFR 98.236(c)(9) by removing the 
text, ``using optical gas imaging instrument per 40 CFR 98.234(a) 
(refer to 40 CFR 98.233(k)), or acoustic leak detections of.'' This is 
because 40 CFR 98.233(k) allows the use of several monitoring methods 
for determining tank vapor vent stack emissions. The text in 40 CFR 
98.236(c)(9) limits the reporters to optical gas imaging and acoustic 
leak detection, which is misleading.
    The EPA is also proposing to amend 40 CFR 98.236(c)(13)(iii)(C) to 
correct for an error in the units associated with emissions from 
isolation valve leakage for centrifugal compressors measured using 
provisions in 40 CFR 98.233. Specifically, EPA is proposing to replace 
the units of ``cubic feet per hour'' with ``metric tons of 
CO2e for each gas'' to align the units of this data 
reporting element to those of the general

[[Page 29942]]

provisions of Part 98, 40 CFR 98.3(c)(4)(i), which require reporting of 
annual emissions in units of mass in metric tons of CO2e. 
EPA seeks comment on this proposed amendment to correct the units for 
this data reporting element.
    Next, the EPA is proposing to amend 40 CFR 98.236(c)(15)(i)(B) by 
updating the incorrect reference to ``Equation W-30'' to read 
``Equation W-30A.'' Similarly, the EPA is proposing to amend 40 CFR 
98.236(c)(15)(i)(C) by updating the incorrect reference to Equation W-
30 to read Equation W-30A. In 40 CFR 98.236(c)(15)(i)(C), the EPA 
proposes to delete the unnecessary reference to ``parameter GHGi.''
    In 40 CFR 98.236(c)(15)(ii)(A), the EPA is proposing to remove the 
text references to ``(a)(4)'' and ``W-3'' because the reporting 
requirements for pneumatic devices are already covered under 40 CFR 
98.236c)(1) and making this reference unnecessary. Similarly, the EPA 
is proposing to delete the reference to ``(a)(8)'' because the 
reporting requirements for population counts in the natural gas 
distribution industry segment are already covered under 40 CFR 
98.236(c)(16).
    Finally, the EPA is proposing to delete ``and CH4'' from 
the reporting requirements for EOR injection pumps in 40 CFR 
98.236(c)(17)(v). The EPA clarified through the December 23, 2011 final 
rule that only CO2 emissions must be calculated from EOR 
injection pump blowdowns (76 FR 80565). Although the calculation 
requirements were clarified in that rule, the harmonizing change was 
not made to remove CH4 from the data reporting requirements. 
This proposed change would make the data reporting requirements 
consistent with the calculation procedures in Equation W-37.
    Emission Factor Tables. First, we are proposing to revise the 
incorrect title of Table W-1A of subpart W by deleting ``Table A-1A'' 
and correcting it to ``Table W-1A.''
    In the December 2011 technical corrections final rule (76 FR 
80592), the emission factors were converted from a standard temperature 
of 68 [deg]F to a standard temperature of 60 [deg]F. The EPA 
inadvertently used an incorrect intermediary version of Table W-1A to 
convert the emission factor. In this proposed rule, the EPA is 
proposing to rectify the emission factors in Table W-1A using the 
correct version of Table W-1A from the November 2010 rule. We note that 
the EPA did receive technical comments on the actual default emission 
factor values in Table W-1A in the December 2011 technical corrections 
final rule (see the Response to Comments document for the final rule, 
comment number EPA-HQ-OAR-2011-0147-0016, Excerpt 30). This proposed 
action merely proposes to correct the error that resulted in December 
2011 from use of an incorrect intermediary table when the emission 
factors were converted from a standard temperature of 68 [deg]F to a 
standard temperature of 60 [deg]F. As stated in the Response to 
Comments document referenced above, the EPA may consider substantive 
changes to the default factors for future rulemakings.
    The EPA made changes to the emission factors for the Eastern United 
States in December 2011 as result of comments on the calculation 
performed to derive these numbers. Similar changes were required for 
the pneumatic devices in the Western United States but were 
inadvertently not made in the December 2011 final rule. Therefore, the 
EPA is proposing to make a similar change to the pneumatic device 
emission factors for the Western United States.
    Finally, we are proposing to amend Table W-5 to provide the cross-
reference for footnote 2, by adding a reference associated with 
footnote 2 to Vapor Recovery Compressor.
3. Overview and Approach to Proposed CBI Determinations
    In this action, the EPA is proposing a small number of revisions to 
the data reporting requirements affecting subpart W reporters. 
Specifically, in this action, the EPA is proposing to make the 
following amendments:
     40 CFR (c)(5)(ii)(D) to clarify that the average internal 
casing diameter must be reported for all wells, as opposed to each 
well.
     40 CFR 98.236(c)(9) to align the reporting requirements 
with the corresponding calculation methodologies in 40 CFR 98.233(k) by 
removing erroneous text.
     40 CFR 98.236(c)(13)(iii)(C) to correct the units of the 
reporting requirements.
     40 CFR 98.236(c)(15)(i)(B) and (C) to remove incorrect 
references and citations.
     40 CFR 98.236(c)(15)(ii)(A) to remove unnecessary text 
which if not removed results in redundancy for reporters.
     40 CFR 98.236(c)(17)(v) to remove reporting of CH4 to make 
the reporting requirements consistent with the calculation procedures.
    For these data elements, the EPA proposed confidentiality 
determinations (for non-inputs), and deferral of reporting (for inputs) 
in a proposed action, Proposed Confidentiality Determinations for the 
Petroleum and Natural Gas Systems Source Category, and Amendments to 
Table A-7 of the Greenhouse Gas Reporting Rule, published on February 
24, 2012 (77 FR 11039). These five amendments are minor clarifications 
that do not change the general meaning of the data elements and 
therefore would not affect the determinations or deferrals proposed in 
that action.

D. Subpart L--Fluorinated Gas Production

1. Background
    In today's rule, we are proposing that greenhouse gas emissions be 
reported in a less detailed manner for the initial two years of 
reporting under subpart L. The proposed changes pertain only to subpart 
L, and would be a temporary change (i.e., for reporting years 2011 and 
2012) to allow the EPA sufficient time to fully evaluate concerns 
recently raised by stakeholders that reporting and public availability 
of process-specific emissions of individual fluorinated GHGs may reveal 
trade secrets. Under subpart L, fluorinated gas producers are currently 
required to report greenhouse gas emissions by chemical for each 
process.\7\
---------------------------------------------------------------------------

    \7\ Greenhouse gas emissions are currently required to be 
reported by chemical for each fluorinate gas production process, 
each fluorinated gas transformation process that is not part of a 
fluorinated gas production process, each fluorinate gas destruction 
process that is not part of a fluorinated gas production or 
transformation process, and venting of residual fluorinated GHGs 
(heels) from containers returned from the field (40 CFR 
98.126(a)(2)).
---------------------------------------------------------------------------

    On January 10, 2012, the EPA published proposed determinations 
regarding whether the Greenhouse Gas Reporting Program data elements in 
eight subparts of Part 98, including subpart L, would or would not be 
entitled to confidential treatment under the CAA (77 FR 1434). In that 
proposed rule, the EPA proposed that the chemical identities and 
quantities of the fluorinated GHG emissions at the process-level, 
reported under subpart L, are ``emission data.'' Under section 114 of 
the CAA, ``emission data'' are not eligible for confidential treatment.
    Two commenters on that proposed rule, the American Chemistry 
Council and 3M Company, raised concerns that the release of certain 
data elements that the EPA proposed to classify as emission data, and 
that therefore would not be eligible for treatment as confidential 
business information, would reveal trade secrets. 3M noted that, due to 
the uniqueness of its production processes, it may be the only U.S. 
producer of fluorinated gases that

[[Page 29943]]

has these trade secret concerns. No other producer of fluorinated gases 
individually raised these concerns in either the subpart L or CBI 
rulemakings. Both commenters stated that the disclosure of the identity 
and quantities of the fluorinated GHGs emitted at the process level, 
from either process vents or fugitive sources, would reveal sensitive 
information regarding individual chemical production processes. 3M 
stated that process-level emission data contain specific information on 
reactants, byproducts, and products that would provide competitors with 
a detailed understanding of 3M's manufacturing process. They noted that 
competitors with knowledge of fluorine chemistry could use such 
information to identify the particular manufacturing pathways used by 
3M. Competitors could then duplicate these processes without having to 
incur research and development costs, placing 3M at a competitive 
disadvantage.
    The American Chemistry Council and 3M Company also expressed 
concern that the disclosure of the identity and quantity of emissions 
at the process level could violate export control regulations. 
Specifically, the commenters stated that the release of some data 
elements would make public information that is subject to Export 
Administration Regulations (EAR) and International Traffic in Arms 
Regulations (ITAR) that prohibit public disclosure for reasons of 
``national security, anti-terrorism, nuclear non-proliferation, and 
chemical and biological weapons security.'' The commenters stated that 
the federal regulations not only control export of products, but also 
export of technical knowledge, such as the design of a product and 
production information, and that the release of process-level emission 
data may provide such insight into the design of a product or 
production information that is export controlled. The commenters stated 
that if the EPA attempted to protect export-controlled information from 
disclosure by implementing ``an export control plan,'' this would be in 
conflict with its position that emission data cannot be withheld from 
the public under the CAA.
    EPA needs additional time to fully evaluate whether these concerns 
are justified and how the rule might be changed to balance these 
concerns with the need to obtain the data necessary to inform the 
development of future GHG policies and programs. Specifically, EPA 
needs additional time to consider these comments, better understand 
whether the concerns raised are unique to one facility/manufacturer, 
and evaluate whether a two-track approach with different levels of 
reporting for different facilities would be feasible. Memorandum: 
Potential Future Subpart L Options in the docket to this rulemaking 
(EPA-HQ-OAR-2011-0147) describes some possible alternative reporting 
frameworks. EPA is currently in the process of evaluating whether the 
potential options described in the memorandum would generate an 
adequate data set upon which to inform the development of future GHG 
policies and programs. We seek comment on whether the options presented 
would address the concerns raised by commenters. Although EPA is 
seeking comment on the alternatives presented in this memorandum, any 
changes to Part 98 would be made through a separate proposed action, 
including accompanying proposed regulatory text changes. That proposal, 
should there be one, would also include proposed confidentiality 
determinations for any long-term proposed changes to the reporting 
requirements in subpart L.
2. Proposed Amendments
    The EPA needs additional time to fully evaluate whether these 
concerns are warranted. As a result, we are proposing amendments that 
would apply for only reporting years 2011 and 2012 to allow the EPA 
sufficient time to evaluate these concerns, and if needed, to make 
permanent changes to the rule. We are proposing a new reporting element 
for reporting years 2011 and 2012, where owners and operators of 
facilities producing fluorinated gases would be required to report 
annual total facility-wide fluorinated GHG emissions, expressed in tons 
of CO2e.\8\ The facilities would not be required to report 
process level emissions or individual fluorinated GHGs for reporting 
years 2011 and 2012. These amendments would apply to subpart L only. 
These proposed amendments do not change any other requirements of Part 
98, including the requirement that these data elements be retained as 
records in a form that is suitable for expeditious inspection and 
review (required for all Part 98 records by 40 CFR 98.3(g)).
---------------------------------------------------------------------------

    \8\ This would include emisions from all fluorinated gas 
production processes, all fluorinated gas transformation processes 
that are not part of a fluorinated gas production process, all 
fluorinated gas destruction processes that are not part of a 
fluorinated gas production process or a fluorinated gas 
transformation process, and venting of residual fluorinated GHGs 
from containers returned from the field.
---------------------------------------------------------------------------

    This proposed action would not have any impact on the EPA's final 
rule issued on August 25, 2011 (76 FR 53057), which deferred the 
deadline for reporting subpart L data elements that are inputs to 
emission equations until March 31, 2015. The data elements listed in 
that action for which the reporting deadline was deferred until March 
31, 2015 are still deferred until that date. For the data elements 
listed below, we are proposing in this action, that owners and 
operators of facilities producing fluorinated gases would not be 
required to submit the information until March 31, 2014 (unless the 
deferral of inputs action mentioned previously has already set forth a 
deferred reporting deadline of March 31, 2015).
     40 CFR 98.3(c)(4)(iii)
     40 CFR 98.126 (a)(2), (a)(3), (a)(4), (a)(6),(b), (c), 
(d), (e), (f), (g), and (h).
    The data element at 40 CFR 98.3(c)(4)(iii) is the subpart A 
reporting requirement that requires reporting of greenhouse gas 
emissions by chemical for each subpart. Again, reporting of this data 
element would be deferred for reporting year 2011 and reporting year 
2012 for subpart L only.
    With these proposed changes, fluorinated gas producers would 
report, under subpart L, only the data elements in 40 CFR 98.126(a)(5) 
(the methods used) and in proposed paragraph 40 CFR 98.126(j) (for 
facility-level CO2e emissions) for reporting year 2011 and 
reporting year 2012. Consistent with 40 CFR 98.126(e), a facility would 
need to include the excess emissions, converted to CO2e, 
that result from malfunctions of the destruction device when reporting 
total facility CO2e under 40 CFR 98.126(j). However, as 
noted in 40 CFR 98.126(j), these excess emissions would not need to be 
reported separately but would be included in the facility-wide 
CO2e reported. While reporters are still reporting 
98.126(a)(5), we are proposing to amend this reporting element to 
require facilities to report the methods used to determine emissions at 
a facility-level rather than linking each method to a particular 
process.
    We note that the data elements in 40 CFR 98.122(a) and (b) refer to 
reporting of GHGs under subpart C of part 98, General Stationary Fuel 
Combustion Sources, and the reporting of fluorinated GHGs under subpart 
O of part 98, HCFC-22 Production and HFC-23 Destruction, respectively, 
and we are not proposing to change them through this action.
    To convert fluorinated GHG emissions into CO2e, the EPA 
is proposing that facilities use Equation A-1 of subpart A. For 
fluorinated GHGs that do not have a GWP listed in Table A-1, facilities 
would be required either to use a default

[[Page 29944]]

GWP or to use their best estimate of the GWP, based on the information 
described in 40 CFR 98.123(c)(1)(vi)(A)(3).\9\ The default GWP used 
would depend on the type of fluorinated GHG. For fully fluorinated 
GHGs, the default GWP would be 10,000, which is based on the average 
GWP of the fully fluorinated GHGs on Table A-1. For the purposes of 
subpart L, EPA is proposing to define ``fully fluorinated GHGs'' as 
``fluorinated GHGs that contain only single bonds and in which all 
available valence locations are filled by fluorine atoms. This includes 
but is not limited to saturated perfluorocarbons, SF6, NF3, SF5CF3, 
fully fluorinated linear, branched and cyclic alkanes, fully 
fluorinated ethers, fully fluorinated tertiary amines, fully 
fluorinated aminoethers, and perfluoropolyethers.'' For other 
fluorinated GHGs, the default GWP would be 2,000, which is based on the 
average GWP of the other fluorinated GHGs on Table A-1. EPA is 
proposing to distinguish between fully fluorinated GHGs and other 
fluorinated GHGs because the former have significantly longer lifetimes 
and higher GWPs than the latter. EPA requests comment on the proposed 
definition of fully fluorinated GHGs and on the default GWPs.
---------------------------------------------------------------------------

    \9\ This is part of the provision of subpart L that allows 
facilities to request to use provisional GWPs to calculate whether 
they must use stack testing to establish an emission factor for a 
vent. Note that EPA is not proposing to approve best-estimate GWPs 
under this action.
---------------------------------------------------------------------------

    We are proposing to add three new data elements that, if a facility 
used one or more default or best-estimate GWPs, it would be required to 
report the shares of its CO2e emissions that were 
respectively based on the default and/or best estimate GWPs. This would 
enable the EPA to understand the potential impact of the default or 
best estimate GWPs on the overall estimated emissions of the facility. 
We are proposing that, facilities using best estimate GWPs be required 
to keep the GWPs, along with the data and analysis that were used to 
develop the GWPs, as records.
    The EPA requests comment on the approach for assigning GWPs to 
fluorinated GHGs without GWPs on Table A-1. If commenters believe that 
another method should be used for calculating GWP values for chemicals 
not listed in Table A-1, they should provide details and rationale for 
the specific method that they recommend.
    The EPA is proposing that the amendments described above apply for 
reporting year 2011 and reporting year 2012. Because the deadline for 
reporting year 2012 reporting is March 31, 2013, just six months after 
the reporting year 2011 reporting deadline, the EPA has determined that 
making these proposed amendments effective for two reporting years 
would allow sufficient time to fully evaluate the concerns raised as 
well as, if needed, make a permanent change to the rule. The EPA 
requests comment on whether these amendments should apply for only 
reporting year 2011 rather than for reporting year 2011 and reporting 
year 2012.
    Because only one company raised concerns that reporting process-
specific emissions by chemical would reveal trade secrets, the EPA is 
also requesting comment on giving fluorinated gas producers the option 
to report all of the subpart L data elements that are currently subject 
to a September 2012 reporting deadline. Fluorinated gas producers that 
have established tracking and reporting systems based on the current 
rule would then be able to report based on their current systems. At 
the same time, this approach would preserve chemical-by-chemical 
reporting at the process level where companies decide to report in this 
manner.
3. Overview and Approach to Proposed CBI Determinations
    As discussed in Section II.D.2 of this preamble, the EPA is 
proposing amendments that would apply to subpart L for reporting years 
2011 and 2012. Owners and operators would be required to report the 
facility's fluorinated GHG emissions only as an annual total expressed 
as CO2e emissions as well as the shares of those emissions 
that were based on the default and/or best estimate GWPs.
    The proposed amendment includes addition of these four reporting 
elements, which are listed below in Table 2 of this preamble.\10\
---------------------------------------------------------------------------

    \10\ 76 FR 30782, May 26, 2011.
    \11\ The CBI determinations of these data categories were 
finalized in the Final CBI Rule (May 26, 2011, 76 FR 30782).

                                 the GWP.
------------------------------------------------------------------------

    In conjunction with the proposed addition of the four data elements 
identified above, we are proposing confidentiality determinations for 
these data elements. Because these four data elements describe 
emissions exhausted to the atmosphere, we are proposing to assign these 
proposed data elements to the ``Emissions'' category. These proposed 
data elements are exactly the same type of data (i.e., information 
regarding the quantity of GHG emissions to the atmosphere) as all of 
the other data elements previously categorized in the ``Emissions'' 
data category in the Final CBI rule. As mentioned above, in the Final 
CBI rule, the EPA determined that the data elements in this data 
category are ``emission data'' under CAA section 114(c) and 40 CFR 
2.301(a)(2)(i). Since the proposed data elements are the same as the 
data elements previously finalized in the ``Emissions'' data category, 
we propose

[[Page 29945]]

that the determination applied to that category also applies to these 
four proposed data elements, and that these data elements would not be 
eligible for CBI treatment.
    As mentioned above, we are also proposing to amend the reporting 
requirement in 98.126(a)(5); however, the proposed amendment is a minor 
change in which facilities are reporting the methods used to determine 
emissions at a facility-level rather than linking each method to a 
particular process. Because the same information would be reported 
(without being linked to a particular process), this change does not 
affect the proposed confidentiality determination that was made for 
this data element in a recent proposal.12 As a result, we are not 
proposing a confidentiality determination for this data element.

III. Statutory and Executive Order Reviews

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

    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

    This action does not impose any new information collection burden. 
These proposed amendments do not make any substantive changes to the 
reporting requirements in any of the subparts for which amendments are 
being proposed. In many cases, the proposed amendments could 
potentially reduce the reporting burden by making the monitoring and 
reporting requirements more clear and to more closely conform to 
industry practices. However, the OMB has previously approved the 
information collection requirements for subparts A on October 30, 2009, 
subpart L on December 1, 2010, subpart W promulgated on November 30, 
2010, subpart TT promulgated on July 12, 2010 under 40 CFR part 98 
under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et 
seq., and has assigned OMB control numbers 2060-0629; 2060-0650; and 
2060-0647; and 2060-0649 respectively. The OMB control numbers for the 
EPA's regulations in 40 CFR are listed in 40 CFR part 9.
    Further information on the EPA's assessment on the impact on burden 
can be found in the 2012 Technical Corrections and Amendments Cost Memo 
in docket number EPA-HQ-OAR-2011-0147.

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 proposed rule 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; and (3) a small organization that is 
any not-for-profit enterprise which is independently owned and operated 
and is not dominant in its field.
    After considering the economic impacts of these proposed rule 
amendments on small entities, I certify that this action will not have 
a significant economic impact on a substantial number of small 
entities. The proposed rule amendments will not impose any new 
requirement on small entities that are not currently required by the 
regulation of subpart A promulgated on October 30, 2009; subpart TT 
promulgated on July 12, 2010; subpart W promulgated on November 30, 
2010, or subpart L promulgated on December 1, 2010.
    Based on the proposed amendments in his action, the EPA has 
provided clarity to address ambiguity in the rule provisions, and has 
proposed corrections where necessary to assist reporters in 
implementation of these subparts.
    Further, the EPA took several steps to reduce the impact of 40 CFR 
part 98 on small entities when developing the final GHG reporting rules 
in 2009 and 2010. For example, the EPA determined appropriate 
thresholds that reduced the number of small businesses reporting. In 
addition, the EPA conducted several meetings with industry associations 
to discuss regulatory options and the corresponding burden on industry, 
such as recordkeeping and reporting. Finally, the EPA continues to 
conduct significant outreach on the GHG reporting program and maintains 
an ``open door'' policy for stakeholders to help inform the EPA's 
understanding of key issues for the industries.

D. Unfunded Mandates Reform Act (UMRA)

    The proposed rule amendments do 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. Thus, the proposed rule amendments are not subject to the 
requirements of section 202 and 205 of the UMRA. This rule is also not 
subject to the requirements of section 203 of UMRA because it contains 
no regulatory requirements that might significantly or uniquely affect 
small governments. The proposed amendments will not impose any new 
requirements that are not currently required for 40 CFR part 98, and 
the rule amendments would not unfairly apply to small governments. 
Therefore, this action is not subject to the requirements of section 
203 of the UMRA.

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. For a more detailed discussion 
about how Part 98 relates to existing state programs, please see 
Section II of the preamble to the final Greenhouse Gas Reporting Rule 
(74 FR 56266, October 30, 2009).
    These amendments apply directly to facilities that supply certain 
products that would result in GHGs when released, combusted or oxidized 
and facilities that directly emit greenhouses gases. They do not apply 
to governmental entities unless the government entity owns a facility 
that directly emits GHGs above threshold levels (such as a landfill), 
so relatively few government facilities would be affected. This 
regulation 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.
    Although section 6 of Executive Order 13132 does not apply to this 
action, the EPA did consult with State and local officials or 
representatives of State and local governments in developing subparts A 
on October 30, 2009; subpart TT promulgated on July 12, 2010; subpart W 
promulgated on November 30, 2010; and subpart L promulgated on December 
1, 2010. A summary of the EPA's consultations with State and local

[[Page 29946]]

governments is provided in Section VIII.E of the preamble to the 2009 
final rule.
    In the spirit of Executive Order 13132, and consistent with EPA 
policy to promote communications between EPA and State and local 
governments, the EPA specifically solicits comment on this proposed 
action from State and local officials.

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

    This action does not have tribal implications, as specified in 
Executive Order 13175 (65 FR 67249, November 9, 2000). The proposed 
rule amendments would not result in any changes to the current 
requirements of 40 CFR part 98. Thus, Executive Order 13175 does not 
apply to this action.
    Although Executive Order 13175 does not apply to this action, the 
EPA sought opportunities to provide information to Tribal governments 
and representatives during the development of the rules for subparts A 
on October 30, 2009; subpart TT promulgated on July 12, 2010; subpart W 
promulgated on November 30, 2010, and subpart L promulgated on December 
1, 2010. A summary of the EPA's consultations with Tribal officials is 
provided Sections VIII.E and VIII.F of the preamble to the 2009 final 
rule and in Section IV.F of the final rule for subpart W.

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 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 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 EPA decides not to use 
available and applicable voluntary consensus standards.
    This proposed rulemaking 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 proposed rule 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 because it is a rule addressing information collection and 
reporting procedures.

Subpart L--[Amended]

    4. Section 98.126 is amended by:
    a. Revising paragraph (a) introductory text.
    b. Revising paragraph (a)(5).
    c. Adding paragraph (j).
    The revisions read as follows:


Sec.  98.126  Data Reporting Requirements.

    (a) All facilities. In addition to the information required by 
Sec.  98.3(c), you must report the information in paragraphs (a)(2) 
through (a)(6) of this section according to the schedule in paragraph 
(a)(1) of this section, except as otherwise provided in paragraph (j) 
of this section or in Sec.  98.3(c)(4)(vii) and Table A-7 of Subpart A 
of this part.
* * * * *
    (5) The methods used to determine the mass emissions of each 
fluorinated GHG, i.e., mass balance, process-vent-specific emission 
factor, or process-vent-specific emission calculation factor, at the 
facility. If you use the process-vent-specific emission factor or 
process-vent-specific emission calculation factor method, report the 
methods used to estimate emissions from equipment leaks.
* * * * *
    (j) Special Provisions for Reporting Years 2011 and 2012 Only. For 
reporting years 2011 and 2012, the owner or operator of a facility must 
comply with paragraphs (j)(1), (j)(2), and (j)(3) of this section.
    (1) Timing. The owner or operator of a facility is not required to 
report the data elements at Sec.  98.3(c)(4)(iii) and Sec.  
98.126(a)(2), (a)(3), (a)(4), (a)(6), (b), (c), (d), (e), (f), (g), and 
(h) of this section until the later of March 31, 2014 or the date set 
forth for that data element at Sec.  98.3(c)(4)(vii) and Table A-7 of 
Subpart A of this part.
    (2) Excess emissions. Excess emissions of fluorinated GHGs 
resulting from destruction device malfunctions must be reflected in the 
reported facility-wide CO2e emissions but are not required 
to be reported separately.
    (3) Calculation and Reporting of CO2e. You must report the total 
fluorinated GHG emissions covered by this subpart, expressed in metric 
tons of CO2e. This includes emissions from all fluorinated 
gas production processes, all fluorinated gas transformation processes 
that are not part of a fluorinated gas production process, all 
fluorinated gas destruction processes that are not part of a 
fluorinated gas production process or a fluorinated gas transformation 
process, and venting of residual fluorinated GHGs from containers 
returned from the field. To convert fluorinated GHG emissions to 
CO2e for reporting under this section, use Equation A-1 of 
Sec.  98.2. For fluorinated GHGs whose GWPs are not listed in Table A-1 
of Subpart A of this subpart, use either the default GWP specified 
below or your best estimate of the GWP based on the information 
described in Sec.  98.123(c)(1)(vi)(A)(3).
    (i) If you choose to use a default GWP rather than your best 
estimate of the GWP for fluorinated GHGs whose GWPs are not listed in 
Table A-1 to this subpart, use a default GWP of 10,000 for fluorinated 
GHGs that are fully fluorinated GHGs and use a default GWP of 2000 for 
other fluorinated GHGs.
    (ii) Provide the total annual emissions across fluorinated GHGs for 
the entire facility, in metric tons of CO2e, that were 
calculated using the default GWP of 2000.
    (iii) Provide the total annual emissions across fluorinated GHGs 
for the entire facility, in metric tons of CO2e, that were 
calculated using the default GWP of 10,000.

[[Page 29948]]

    (iv) Provide the total annual emissions across fluorinated GHGs for 
the entire facility, in metric tons of CO2e, that were 
calculated using your best estimate of the GWP.
    5. Section 98.127 is amended by adding paragraph (k) to read as 
follows:


Sec.  98.127  Records that must be retained.

* * * * *
    (k) For fluorinated GHGs whose GWPs are not listed in Table A-1 to 
this subpart, maintain records of the GWPs used to calculate facility-
wide CO2e emissions. Where you used your best estimate of 
the GWP, maintain records of the data and analysis used to develop that 
GWP, including the data elements at Sec.  98.123(c)(1)(vi)(A)(1)-(3).
    6. Section 98.128 is amended by adding the definition of ``Fully 
fluorinated GHGs'' in alphabetical order to read as follows:


Sec.  98.128  Definitions.

* * * * *
    Fully fluorinated GHGs means fluorinated GHGs that contain only 
single bonds and in which all available valence locations are filled by 
fluorine atoms. This includes but is not limited to saturated 
perfluorocarbons, SF6, NF3, 
SF5CF3, fully fluorinated linear, branched and 
cyclic alkanes, fully fluorinated ethers, fully fluorinated tertiary 
amines, fully fluorinated aminoethers, and perfluoropolyethers.

service components in reference to Table W-1A of this subpart and major 
natural gas equipment in reference to Table W-1B of this subpart. Major 
equipment and components associated with crude oil wells are considered 
crude service components in reference to Table W-1A of this subpart and

equipment leak sources calculated in Equation W-30B in paragraph (q)(8) 
of this section and the count of meter/regulator runs located at above 
grade transmission-distribution transfer stations that were monitored
