ICR WORKSHEET CHANGE

2013 Revisions to the Greenhouse Gas Reporting Rule and Confidentiality Determinations for New or 

Substantially Revised Data Elements: Changes to the Data Reporting Requirements 

1. OVERVIEW

In October 2009, EPA finalized the Greenhouse Gas Reporting Rule (74 FR 56260; October 30, 

2009) under 40 CFR part 98 (“Part 98”). The 2009 final Part 98, which became effective on December 

29, 2009, includes reporting of greenhouse gases (GHGs) from certain facilities and suppliers. 

Subsequent rules provide corrections and clarification on existing requirements; include requirements for 

additional facilities and suppliers; require reporters to provide information about parent companies, 

NAICS code(s), and whether emissions are from cogeneration; and finalize confidentiality 

determinations. Specifically, in 2010 and 2011, EPA promulgated requirements for subparts T, FF, II, and 

TT (75 FR 39736; July 12, 2010); information about parent companies, NAICS codes(s), and 

cogeneration (75 FR 57669; September 22, 2010); subpart W (75 FR 74458; November 30, 2010); 

subpart I, L, DD, QQ, and SS (75 FR 74774; December 1, 2010); subpart RR and UU (75 FR 75060; 

December 1, 2010) and confidentiality determinations (76 FR 30782; May 26, 2011). Collectively, the 

Greenhouse Gas Reporting Rule and its associated rulemakings are referred to as the Greenhouse Gas 

Reporting Program (GHGRP).

In 2013, EPA revised and renewed the GHGRP Information Collection Request (ICR) to update 

the burdens and costs imposed by all of the current ICRs under the GHGRP (EPA ICR number 2300.10, 

OMB control number 2060-0629).

EPA proposed amendments to Part 98 in the “2013 Revisions to the Greenhouse Gas Reporting 

Rule and Confidentiality Determinations for New or Substantially Revised Data Elements” (the 2013 

Revisions) (78 FR 19802, April 2, 2013). EPA is finalizing the amendments in this rulemaking, including

revisions to the Global Warming Potentials (GWPs) in Table A-1 of subpart A to match the GWPs 

published by the Intergovernmental Panel on Climate Change (IPCC) in the 2007 Fourth Assessment 

Report. Additionally, EPA is finalizing technical corrections, clarifying revisions, and other amendments 

to 33 subparts of the GHGRP. Finally, EPA is finalizing confidentiality determinations for new or 

substantially revised data elements included in the amendments in this rulemaking.

2. TECHNICAL CORRECTIONS, CLARIFYING, AND OTHER AMENDMENTS 

AFFECTING THE PRIOR ICR FOR THE GHG REPORTING RULE

Section 2 of this memorandum describes the clarifications, corrections, and modifications to the 

reporting requirements associated with the ICR for the subparts affected by the 2013 Revisions. 

Additional minor corrections, including minor edits to Part 98, are presented in the Table of 2013 

Revisions (see Docket Id. No. EPA-HQ-OAR-2012-0934), and are not discussed in this memorandum.

The final amendments do not make any substantive changes to the reporting requirements in any 

of the subparts for which amendments are being finalized. As discussed in Section 2.1 of this 

memorandum, the final amendments to subpart A include revisions of the existing GWPs in Table A-1 of 

subpart A, which will affect the total number of facilities reporting under the GHGRP. The amendments 

to the reporting requirements in the source category-specific subparts generally do not change the nature 

of the data reported and do not result in a significant increase in collection burden for reporters.

2013 Revisions to the Greenhouse Gas Reporting Rule

2.1 Subpart A – General Provisions

EPA is amending subpart A by updating the GWP values of certain compounds in Table A-1 of subpart A. These changes affect facilities 

and suppliers under Part 98 reporting the following GHGs: methane (CH4), nitrous oxide (N2O), sulfur hexafluoride (SF6), certain 

hydrofluorocarbons, certain perfluorocarbons, and certain other fluorinated GHGs. EPA estimates that 184 new reporters will be required to report 

under the GHGRP due to the revised GWP values with a first year incremental cost of $2,195,400 ($2011) and an incremental annual cost of 

$1,316,750 per year. The annual costs for the additional reporters is an approximate increase of 1.3 percent above the existing reporters cost of 

compliance with Part 98. The changes to Table A-1 do not pose an increase in the collection burden for existing reporters, with the exception of 

some landfills which may exit the program later than expected. Table 2.1-A lists the costs for additional reporters and presents the first year and 

subsequent year costs for the affected source categories.

a Subpart HH cost impact includes the reporting costs for 43 closed landfills that will exit the reporting program later than 

expected. Similarly, subpart TT cost impact includes the cost for 8 closed facilities.

In addition to the amendments to GWP values in Table A-1, EPA is finalizing corrections and other clarifications to certain provisions of 

subpart A. EPA is finalizing an amendment to require facilities to report their latitude and longitude if the facility does not have a physical street 

address and a provision to include instructions for the reporting of a United States parent company legal name and address. EPA is also requiring 
Information Collection Request Worksheet Change Memo for the 

2013 Revisions to the Greenhouse Gas Reporting Rule

facilities to indicate if one or more plant-sites have been assigned a “plant code” either by the Department of Energy’s (DOE) Energy Information 

Administration (EIA) or by the EPA’s Clean Air Markets Divisions (CAMD). Additionally, EPA is amending 40 CFR 98.3(h)(4) to clarify the 

provisions for requesting an extension of the 45-day period for submission of revised reports in 40 CFR 98.3(h)(1) and (2). EPA is also revising 

several definitions under subpart A.

Table 2.1-B lists the significant changes to reporting requirements under subpart A and provides an indication of the change in reporting 

burden for facilities.

Markets Division (CAMD).

New

None – requires reporting of 

information that facilities are

EPA has reviewed the amendments to subpart A and determined that, other than the amendments to the GWP values in Table A-1, the 

technical corrections, clarifying and other amendments provide either additional clarification regarding the existing regulatory requirements, or 

minor revisions to the reporting requirements. These amendments do not change the type of information that must be collected at the facility, nor 

do they impact the number of respondents. In addition, the changes do not affect how GHG emissions or quantities are calculated. These changes 

do not require any additional monitoring, calculation, or data collection above what was already included in Part 98 and, therefore, impose no 

additional collection burden for facilities. 

2.2. Subpart C – General Stationary Fuel Combustion Sources

For subpart C, EPA is expanding the use of the Tier 1 methodology to be used for Table C-1 fuels that are combusted in a unit with a 

maximum rated heat input capacity greater than 250 million British thermal units (mmBTU) per hour, if the fuel provides less than 10 percent of 

the annual heat input to the unit and the use of Tier 4 is not required. Expanding the use of the Tier 1 methodology will reduce monitoring burden 

for facilities that are subject to the requirements of subpart C and combust small amounts of secondary fuels. 
Information Collection Request Worksheet Change Memo for the 

2013 Revisions to the Greenhouse Gas Reporting Rule

EPA is also revising several emission factors and higher heating values (HHVs) for fuels in Table C-1 including, but not limited to, coals 

and coke, liquefied petroleum gases (e.g. propane, propylene, ethane, etc.), wood and wood residuals, and biogases. Of the changes to emission 

factors, the change with the largest percent difference (approximately 11 percent) is the emission factor for coke (which is also being revised to 

read “coal coke”). Approximately 1.6 percent of facilities that reported under subparts C and D for reporting year 2011 indicated using coke as a 

fuel for combustion in addition to other fuels. The majority of coal coke produced (92 percent) in the United States is used in blast furnaces for the 

conversion of iron ore into iron (U.S. EPA, 2001). The emission factor for coal coke is not used in the calculation of carbon dioxide (CO2)

emissions for iron furnaces. Due to the small number of facilities that reported using coke as a fuel, and because facilities do not typically use coke 

as the primary fuel, no additional facilities will be required to report under subpart C due to an increase in calculated CO2 emissions resulting from 

the increase to the coke emission factor in Table C-1.

Table 1.2 lists the significant changes to reporting requirements under subpart C and provides an indication of the change in reporting

burden for facilities.

EPA has reviewed the amendments to subpart C and determined that the technical corrections, clarifying and other amendments provide 

either additional clarification regarding the existing regulatory requirements, or minor revisions to the reporting requirements. These amendments 

do not change the type of information that must be collected at the facility, nor do they impact the number of respondents. These changes do not 

require any additional monitoring, calculation, or data collection above what was already included in Part 98 and, therefore, impose no additional 

collection burden for facilities. 

2.3. Subpart H – Cement Production

EPA is amending subpart H to require reporting of facility-wide cement production. This change will provide consistency in the reporting 

requirements for facilities using continuous emissions monitoring systems (CEMS) and not using CEMS. This amendment does not change the 

type of information that must be collected at the facility, nor does it impact the number of respondents. This change does not require any 

additional monitoring, calculation, or data collection above what was already included in Part 98 and, therefore, imposes no additional collection 

burden for facilities.

Table 2.3 lists the significant changes to reporting requirements under subpart H and provides an indication of the change in reporting 

burden for facilities.

2.4. Subpart K – Ferroalloy Production

EPA is finalizing two corrections to subpart K. First, EPA is correcting a term in Equation K-3. Second, EPA is adding the reporting 

requirement listed in Table 2.4.

Table 2.4 Changes to Reporting Requirements under Subpart K – Ferroalloy Production

EPA has reviewed the amendments to subpart K and determined that the technical and added reporting requirement does not change the 

type of information that must be collected at the facility, nor do they impact the number of respondents. These changes do not require any

2013 Revisions to the Greenhouse Gas Reporting Rule

6

additional monitoring, calculation, or data collection above what was already included in Part 98 and, therefore, impose no additional collection 

burden for facilities.

2.5. Subpart L – Fluorinated Gas Production

EPA is amending subpart L to extend temporary, less detailed reporting requirements for fluorinated gas producers for an additional year. 

The extension requires the same less detailed reporting for reporting year 2013 as for reporting years 2011 and 2012. The extension allows the 

EPA, as well as stakeholders, to consider the various options for reporting emissions under subpart L in conjunction with EPA’s proposed changes 

regarding reporting inputs to emission equations for subpart L. These amendments represent an extension of a temporary reduction in reporting 

requirements and, therefore, impose no additional collection burden for facilities. 

2.6 Subpart N – Glass Production

In addition to clarify several requirements and equations terms, EPA is revising the monitoring methods used to measure carbonate-based 

mineral mass-fractions to allow for more accurate measurement methods and provide flexibility for reporters. EPA is requiring that facilities use 

consensus standards that specify X-ray fluorescence (XRF). Based on the similarity in cost of the current standards (ASTM D-4326 and D-6349) 

and XRF, the revised measurement methods do not impose any additional collection burden on facilities subject to subpart N.

2.7 Subpart O – HFC-22 Production and HFC-23 Destruction

EPA is adding a sentence to 40 CFR 98.156(c) to clarify how to report the HFC-23 concentration at the outlet of the destruction device in 

the event the concentration falls below the detection limit of the measuring device. This amendment is a minor revision to the reporting

requirement and does not change the type of information that must be collected at the facility. The change does not require any additional 

monitoring, calculation, or data collection above what was already included in Part 98 and, therefore, imposes no additional burden for facilities.

2.8 Subpart P – Hydrogen Production

EPA is finalizing several corrections and clarifications to subpart P to clarify the fuel and feedstock material balance approach and to 

provide additional flexibility for reporters using Equations P-1 and P-2, and chromatographic analysis. EPA is also removing the requirement to 

report hydrogen and ammonia production for all units combined. EPA has reviewed the amendments to subpart P and determined that these 

changes do not require any additional monitoring, calculation, or data collection above what was already included in Part 98 and, therefore, impose 

no additional collection burden for facilities.

2.9 Subpart Q – Iron and Steel Production
Information Collection Request Worksheet Change Memo for the 

2013 Revisions to the Greenhouse Gas Reporting Rule

7

EPA is finalizing multiple amendments to subpart Q to clarify certain provisions and calculation methods. First, EPA is including direct 

reduction furnaces not co-located with an integrated iron and steel manufacturing process, as these furnaces were inadvertently excluded from the 

original rulemaking. Because this change only impacts one facility that is already reporting under subpart Q, this change does not impose any 

additional collection burden on reporters. 

Second, EPA is amending Equation Q-5 in subpart Q to account for the use of gaseous fuels in EAFs. Because facilities currently 

determine the mass rate of fuels using the procedures in subpart C and must report the annual volume of gaseous fuels, reporters will not need to 

collect or record any additional information to account for the use of gaseous fuels in equation Q-5 in subpart Q. Therefore, this change imposes 

no additional collection burden on reporters subject to subpart Q.

2.10. Subpart X – Petrochemical Production

EPA is finalizing several substantial changes to subpart X. EPA is requiring reporters using CEMS to determine CO2 emissions to use 

Equation C-10 of subpart C to Part 98 to calculate CH4 and N2O emissions from burning process off-gas. Because Tier 4 units can use best 

available information to estimate fuel use (see 40 CFR 98.22(c)(4)(i) and 40 CFR 98.33(c)(4)(ii)(C)), this change imposes no additional collection 

burden on reporters subject to subpart Q. 

EPA is also finalizing several changes for those reporters that use the mass balance calculation method. First, EPA is allowing flexibility 

for the source of the carbon measurements for feedstocks and products. Next, EPA is allowing the alternative sampling requirements for 

feedstocks and products when the composition is greater than 99.5 percent of a single compound to be used during all times that the average 

monthly concentration is above 99.5 percent. Additionally, EPA is allowing the inputs for gaseous feedstock and products to be measured on 

either a mass basis or on a volume basis in Equation X-1. EPA is also allowing facilities to use industry standard practices for the analysis of 

carbon black feedstock oils and carbon black products, instead of a specified list of standards currently provided in 40 CFR 98.244(b)(4). There is 

no additional collection burden as a result of these changes since they allow additional flexibility for reporters. 

EPA is clarifying the requirements for flares to specify that facilities must conduct monitoring and quality assurance in accordance with 40 

CFR 98.254(b) through (e) for each flare gas flow meter, gas composition meter, and/or heating value monitor that is used to comply with 40 CFR 

98.253(b)(1) through (3), which was EPA’s original intent. We are specifying in the final amendments that reporters must implement the 

applicable QA/QC requirements by January 1, 2015. Since the change is a clarification, no additional collection burden is imposed on reporters 

subject to subpart X.

EPA is clarifying the missing data procedures for missing feedstock and product flow rates, missing feedstock and product carbon 

contents, and missing molecular weights for gaseous feedstocks and products. EPA is also adding missing data requirements for flares. Because 

these amendments only clarify the existing missing data procedures for subpart X facilities, these amendments do not impose any additional

collection burden on reporters. 
Information Collection Request Worksheet Change Memo for the 

2013 Revisions to the Greenhouse Gas Reporting Rule

8

Amendments to reporting requirements under subpart X are presented in Table 2.10. These changes are minor revisions and clarifications 

to the existing reporting requirements and do not require facilities to install any additional monitoring equipment or develop any additional 

monitoring and record keeping procedures; therefore, these reporting requirements result in an insignificant increase in collection burden for 

facilities reporting under subpart X.

CH4 and N2O attributable to 

combustion of off gas, rather than 

the fraction of all emissions.

None - change is minor revision to 

reporting element and requires 

reporting of information that 

facilities are expected to have 

readily available.

2.11. Subpart Y – Petroleum Refineries
Information Collection Request Worksheet Change Memo for the 

2013 Revisions to the Greenhouse Gas Reporting Rule

9

EPA is finalizing changes, technical corrections, and clarifying amendments to subpart Y. In addition to clarifying calculation 

methodologies and revising references, we are clarifying two reporting elements, which are listed in Table 2.11. Since the changes to the reporting 

elements in Table 2.11 are clarifications, no additional collection burden is imposed on reporters subject to subpart Y.

2.12. Subpart Z – Phosphoric Acid Production

EPA is finalizing several clarifying amendments to subpart Z. As presented in Table 2.12, EPA is changing the reporting requirement of 

the annual permitted phosphoric acid production capacity to the annual phosphoric acid production capacity. This change does not impose any 

additional collection burden on reporters since the information should be readily available in facility records. EPA is also adding a reporting 

requirement to report the number of times missing data procedures were used to estimate the CO2 content of the phosphate rock. This change does

not impose any additional collection burden for reporters because facilities are already required to keep records for estimating missing values of 

CO2 content of phosphate rock per 40 CFR 98.265(a), and no new information is collected.

2.13. Subpart AA – Pulp and Paper Production
Information Collection Request Worksheet Change Memo for the 

2013 Revisions to the Greenhouse Gas Reporting Rule

10

EPA is correcting emission factors and clarifying the information that must be reported under subpart AA. First, EPA is removing the 

references to site-specific emission factors in 40 CFR 98.273(a)(3), 40 CFR 98.276(e), and Equation AA-1. EPA is also correcting printing errors, 

inadvertent omissions, and inconsistencies from Table AA-1 and AA-2. These changes do not impose any additional collection burden since no 

additional reporting requirements or monitoring is required. 

EPA is also amending the reporting requirement for the annual pulp and/or paper production information that must be reported. As shown 

in Table 2.13, EPA is clarifying that the annual production information must consist of the production of unbleached virgin pulp produced onsite 

during the reporting year, prior to application of any off-machine coatings. EPA clarified the production reporting requirement under 40 CFR 

98.276(k) in the “Frequently Asked Questions” section of EPA’s supporting website for the GHGRP. EPA specified that facilities should report 

virgin chemical pulp production at the mill separate from the mass of paper product exiting all of the paper machine(s) at the mill; therefore, EPA 

is clarifying the reporting requirement and removing the requirement to report paper production. No new reporting or monitoring is required by 

reporters; therefore, this change does not impose any additional collection burden on reporters subject to subpart AA.

2.14 Subpart BB – Silicon Carbide Production

For subpart BB, Silicon Carbide Production, EPA is removing the requirement for facilities to report CH4 emissions from silicon carbide 

process units or furnaces. Additionally, EPA is amending subpart BB such that facilities will calculate and report CO2 emissions for all process 

units and furnaces combined, instead of each process unit or production furnace. The remaining changes to subpart BB either support these 

amendments, or provide minor clarifications of the rule text. Both of these major changes reduce the collection burden for facilities subject to 

subpart BB.

2.15 Subpart DD – Electrical Transmission and Distribution Equipment Use 

EPA is finalizing two technical corrections to subpart DD to correct the accuracy and precision requirements for weighing cylinders. 

Instead of scale accuracies of “2 pounds of the scale’s capacity,” EPA is revising the rule to be consistent with their original intention of “2 pounds 

of true weight.” This accuracy requirement was noted in the technical support document to subpart DD, EPA’s response to public comments for 

subpart DD, and the preamble to the final Part 98 (74 FR 56260, October 30, 2009). In our response to comments, we noted that a “2 pounds of 

true weight” requirement would be less burdensome than the 1 percent of true weight requirement originally proposed. Therefore, amending the 

rule to reflect EPA’s original intent imposes no additional collection burden.

2.16. Subpart FF – Underground Coal Mines

EPA is finalizing numerous amendments to subpart FF. The majority of the changes include terminology revisions that more accurately 

reflect industry operations, correction of subscript errors, and minor clarifications of rule text. More substantially, EPA is including the reporting 

of the data elements identified in Table 2.16. All of these data elements are readily available to reporters and do not require additional monitoring 

equipment or development of additional monitoring and record keeping procedures; therefore, the changes to subpart FF impose an insignificant 

collection burden to covered facilities.

2.17. Subpart HH – Municipal Solid Waste Landfills

For subpart HH, EPA is removing the option to used measured values for the degradable organic carbon content in Equation HH-1. EPA is 

also clarifying that the fraction by volume of CH4 in the landfill gas, used in Equation HH-1, should be corrected to zero percent oxygen. 

Additionally, EPA is reducing the measurement frequency for sampling CH4 concentrations from weekly to monthly for the parameter “N” in 
Information Collection Request Worksheet Change Memo for the 

2013 Revisions to the Greenhouse Gas Reporting Rule

12

Equation HH-4. To clarify how to calculate CH4 emissions at landfills with gas collection systems that have multiple measurement locations 

and/or multiple destruction devices, EPA is amending Equations HH-6, HH-7, and HH-8 and surrounding text to generalize these equations and to 

refer to oxidation fractions in Table HH-4. EPA is finalizing the oxidation fraction values in Table HH-4 as proposed, with the exception that we 

are limiting the landfills that can use these new CH4 flux-dependent oxidation fractions to those that have cover soils of 24 inches or more over a 

majority of the landfill area containing waste.

EPA is also making several more minor clarifications and amendments including removing duplicative reporting requirements. We are 

finalizing amendments that CH4 recovery calculated using Equation HH-4 and the annual operating hours of the gas collection systems are to be 

reported separately for each measurement location. Because 40 CFR 98.343(b)(1) and (2) require use of Equation HH-4 separately for each 

monitoring location, it is clear that the CH4 recovery and the fraction of hours the recovery system operated needs to be determined separately for 

each measurement location as these are separate inputs for Equations HH-6 and HH-8 when multiple measurement locations are used. Since this 

change is a clarification, no additional collection burden is imposed on reporters subject to subpart HH.

We are also providing a very limited exclusion within 40 CFR 98.340 for certain closed landfills that have not previously had to report 

under subpart HH, but would newly be required to report starting in reporting year 2014 because the amended CH4 GWP causes them to exceed 

the 25,000 metric tons CO2e emissions threshold for the first time. We have added this exclusion to remove the burden for these closed landfills, 

who would otherwise be required to estimate historical waste quantities and develop their first annual report.

Amendments to reporting requirements under subpart HH are presented in Table 2.17. Although 40 CFR 98.346(h), (i)(5), (i)(8), (i)(10), 

and (i)(11) include new reporting requirements, facilities are not required to install any additional monitoring equipment or develop any additional 

monitoring and record keeping procedures; therefore, these additional reporting requirements have no significant impact on the collection burden 

for facilities reporting under subpart HH.

2.18. Subpart LL – Suppliers of Coal-Based Liquid Fuels

EPA is finalizing several amendments to subpart LL. In addition to providing minor clarification for reporting requirements, EPA is 

removing the requirements at 40 CFR 98.386(a)(1), (a)(5), (a)(13), (b)(1) and (c)(1) for each facility, importer, and exporter to report the annual 

quantity of each product or natural gas liquid on the basis of the measurement standards method or industry standard practice used. Removing 

these requirements results in a net decrease in the collection burden for reporters subject to subpart LL since this requires less detailed reporting 

under subpart L than would have otherwise been required by the December 2010 subpart L final rule.

2.19 Subpart MM – Suppliers of Petroleum Products

In addition to several minor correction and clarifications, EPA is finalizing several technical corrections for subpart MM. First, EPA is 

amending the equipment calibration requirements for petroleum products suppliers to be consistent with other Part 98 calibration requirements to 

allow for postponement of calibrations for units and processes that operate continuously with infrequent outages and provide flexibility for 

reporters meeting the equipment calibration requirements. Next, EPA is removing the requirements of 40 CFR 98.396(a)(1), (a)(5), (a)(13), (b)(1) 

and (c)(1) for each facility, importer, and exporter to report the annual quantity of each petroleum product or natural gas liquid on the basis of the 

measurement standard method or industry standard practice used. EPA is also removing the requirements of 40 CFR 98.396(a)(4), (a)(8), (a)(15), 

(b)(4), and (c)(4) for each facility, importer, and exporter to report a complete list of methods used to measure the annual quantities reported for 

each product or natural gas liquid. In another step to reduce recordkeeping and reporting burden, the reporting requirements for crude oil at 40 

CFR 98.396(a)(20) are changed to require only the annual quantity of crude oil. EPA is also eliminating the requirement to measure the API 

gravity of each batch of crude oil at 40 CFR 98.394(d). EPA is adding and revising several definitions and revising the default density and 

emission factors in Table MM-1 in subpart MM. The changes to subpart MM provide additional flexibility for reporters and reduce the 

information collection burden for those facilities required to report under subpart MM.
Information Collection Request Worksheet Change Memo for the 

2013 Revisions to the Greenhouse Gas Reporting Rule

2.20. Subpart NN – Suppliers of Natural Gas and Natural Gas Liquids

EPA is finalizing several technical corrections to subpart NN. First, EPA is amending the definition of Local Distribution Companies 

(LDC) to clarify that for LDCs that operate in multiple states, the operations in each state are considered a separated LDC. EPA is also clarifying 

that interstate and intrastate pipelines delivering natural gas either directly to major industrial users or to farm taps upstream of the LDC inlet are 

not included in the definition of an LDC. These clarifications do not impose any additional burden on reporters. In “Q286” of the “Frequently 

Asked Questions” section of EPA’s supporting website for the GHGRP, EPA initially clarified its intent that the owner/operator of each LDC that 

is regulated as a separate operating company by State public utility commissions or that operate as independent municipally–owned distribution 

systems must submit an annual report. Therefore, the clarifications are a follow-up to previous guidance and no additional owners/operators are

required to report as a result of the change. 

EPA is also changing the calculation and reporting requirements that require LDCs to report the annual volume of natural gas delivered to 

each meter registering supply equal to or greater than 460,000 million standard cubic feet (Mscf). EPA is finalizing a requirement that if the LDC 

knows, based on readily available information, that multiple meters serve one large end user facility (defined in the final rule as a facility receiving 

a total of greater than 460,000 Mscf during the year), the LDC is required to report these deliveries per facility rather than per meter. If the LDC 

does not know if the series of meters serve an individual end user or multiple facilities, the LDC may continue to report deliveries to individual 

meters. Because LDCs are able to report on a per facility, rather than per meter basis, the collection burden is reduced. 

EPA is amending part of the calculation methodology in subpart NN. Subpart NN currently requires the use of a single emission factor for 

all types of gas streams accounted for in Equation NN-5. Because the characteristics of these streams may differ, EPA is replacing equation NN-5 

with two equations, NN-5a and NN-5b. The greenhouse gas quantity associated with the net amount of natural gas that is placed into or removed 

from storage during the year is to be calculated using equation NN-5a. Emissions that would result from the combustion or oxidation of natural gas 

received by the LDC that bypassed the city gate are calculated using Equation NN-5b, which allows the use of different emission factors for 

different streams of gas. Additionally, EPA is changing Equation NN-6 to incorporate the two NN-5 equations. Reporters are only required to 

modify their calculation methodology and are not be required to install any additional monitoring equipment. Therefore, no additional collection 

burden is imposed on facilities required to report under subpart NN because of these changes.

As presented in Table 2.20, EPA is also requiring the reporting of the quantity of o-grade, y-grade, and other types of bulk natural gas 

liquids (NGLs) received, and the quantity not fractionated, but supplied downstream. Reporters are not required to purchase or install any new 

monitoring equipment as a result of these reporting requirements since (per 40 CFR 98.404(a)(1)) fractionators and LDCs are required to 

determine quantities using methods in common use in the industry for billing purposes as audited under existing Sarbanes Oxley regulation.

Therefore, these changes do not present an additional collection burden on facilities subject to subpart NN.

EPA is finalizing multiple revisions to subpart QQ. In addition to minor corrections and clarifications, EPA is removing the following 

reporting requirements: 40 CFR 98.436(a)(5), (a)(6)(iv), (b)(5), and (b)(6)(iv). EPA is also revising the reporting requirements presented in Table 

2.21. The removal of reporting requirements reduce the collection burden for facilities required to report under subpart QQ.

In addition to minor corrections and clarifications to subpart RR, EPA is adding a reporting requirement, presented in Table 2.22, for 

facilities to report the standard or method used to calculate the mass or volume of contents in containers that is redelivered to another facility 

without being injected into the well. The data element does not require additional data collection or monitoring from reporters and is not a 

significant change. Therefore, this amendment does not add any collection burden for reporting entities.

2.23. Subpart TT – Industrial Waste Landfills

EPA is finalizing multiple changes to subpart TT. EPA is revising definitions in Equation TT-1 and TT-7 and correcting Equation TT-7 by 

deleting an erroneous term. EPA is also making a change to clarify that the number of waste streams for which Equation TT-1 is used includes the 

number of "inert" waste streams disposed of in the landfill. Additionally, EPA is expanding the provisions to determine volatile solids 

concentration for historically managed waste streams so that they may also be used for determining a site-specific DOC value for historically 

managed waste streams. EPA is also eliminating duplicative reporting requirements and to clarify the requirements for reporters when using 

Equations TT-4a or TT-4b. EPA is finalizing amendments to revise the oxidation fraction default value (“OX”) in Equation TT-6 to reference the 

new default oxidation factors in Table HH-4; however, we have revised the amendments to limit the new oxidation factors to landfills with soil 

covers of at least 24 inches for a majority of the landfill area containing waste, and to allow the continued use of the 0.10 default oxidation factor 

for facilities that do not meet these requirements. EPA is also making changes to Table TT-1 to include the DOC default value of 0.09 for 

“Industrial Sludge,” and the corresponding k-values. None of the changes to subpart TT require any additional monitoring or recordkeeping and 

reporting by facilities, therefore these changes do not impose any additional collection burden. Amendments to the reporting requirements under 

subpart TT are presented in Table 2.23.

facilities to report the purpose of CO2 injection (i.e., Research and Development project exemption from subpart RR, enhanced oil or gas recovery, 

acid gas disposal, or some other reason). EPA is also adding a requirement for facilities to report the standard or method used to calculate the 

parameters for CO2 received in containers. None of these reporting requirements require facilities to collect any additional data or install and 

operate any additional monitoring equipment. As a result, the changes impose no significant collection burden on facilities required to report under

3. FINAL CONFIDENTIALITY DETERMINATIONS AFFECTING THE PRIOR ICR FOR THE GHG REPORTING 

RULE
Information Collection Request Worksheet Change Memo for the 

2013 Revisions to the Greenhouse Gas Reporting Rule

20

EPA is finalizing confidentiality determinations for all newly finalized or substantially revised (i.e., requiring additional or different data 

to be reported) data elements in subparts A, H, K, X, Y, Z, AA, FF, HH, NN, QQ, RR, TT, and UU. We are assigning each of the newly finalized

or substantially revised data elements in these subparts to one of the direct emitter or supplier data categories created in the 2011 Final CBI Rule 

(76 FR 30782, May 26, 2011). EPA is not making final confidentiality determinations for data elements assigned to the inputs to emission 

equations category in the 2013 Revisions.

EPA has reviewed the confidentiality determinations and concluded that final determinations do not change the type of information that 

must be collected at the facility, nor do they impact the number of respondents. In addition, the confidentiality determinations do not affect how 

GHG emissions or quantities are calculated. The determinations do not require any additional monitoring, calculation, or data collection above 

what was already included in Part 98 and, therefore, impose no additional collection burden for facilities.

Please see the memorandum titled “Final data category assignments and confidentiality determinations for new and substantially revised 

data elements in the final ‘2013 Revisions to the Greenhouse Gas Reporting Rule and Confidentiality Determinations for New or Substantially 

Revised Data Elements’” (“Confidentiality Determinations Memorandum”) in Docket Id. No. EPA-HQ-OAR-2012-0934 for a list of the new or 

substantially revised data elements, their final category assignments, and their confidentiality determinations (whether categorical or individual) 

except for those assigned to the inputs to equations category.
