Greenhouse Gas Reporting Rule: 2015 Revisions and C onfidentiality Determinations for

Petroleum and Natural Gas Systems; Final Rule

(40 CFR Part 98, subpart W) September 2015

Part A of the Supporting Statement

1. IDENTIFICATION OF THE INFORMATION COLLECTION

1(a) Title and Number of the Information Collection
Recordkeeping and Reporting Requirements for Petrol eum and Natural Gas Systems (40 CFR part 98, Subpart W). The OMB Control number is 2060-0629 and the EPA ICR tracking
number is 2300.16.

1(b) Short Characterization
In response to the FY2008 Consolidated Appropriatio ns Act (H.R. 2764; Public Law 110-161) and under authority of the Clean Air Act ( CAA), the EPA finalized the Greenhouse Gas Reporting Rule (74 FR 56260; October 30, 2009). The Greenhouse Gas Reporting Rule is referred to as 40 CFR Part 98 (hereafter referred t o as “Part 98”) and implementation of Part 98 is referred to as the Greenhouse Gas Reporting Prog ram (GHGRP). This supporting statement
addresses information collection activities that wi ll be imposed by “Greenhouse Gas Reporting Rule: 2015 Revisions and Confidentiality Determinat ions for Petroleum and Natural Gas Systems; Final Rule”. Part 98, which became effective on December 29, 200 9, requires that certain facilities and suppliers emitting above certain threshold leve ls of carbon dioxide (CO 2 ) equivalent (CO 2 e) monitor and report emissions of greenhouse gases (G HGs). A subsequent rule was published on November 30, 2010 finalizing the requirements for t he petroleum and natural gas systems source category (hereafter referred to as “subpart W”) at 40 CFR part 98, subpart W (75 FR 74458).Page 2 September 2015

The EPA is adding reporting requirements for two ne w industry segments, adding reporting requirements for completions and workover s of oil wells with hydraulic fracturing, and adding requirements to report well identification n umbers for certain sources. These revisions are expected to increase respondent burden. See Appendi x A for a complete list of additions to the reporting requirements. Potential new respondents are owners or operators o f petroleum and natural gas systems that meet the requirements of §98.2(a)(2) and the r eporting thresholds of §98.231. New respondents are required to report data elements ac cording to §98.236, and maintain records according to §98.237. Existing respondents must rep ort and maintain records as specified in Part
98. Approximately 3,300 respondents will be subject to the regulation and this rulemaking is expected to increase labor costs for subpart W faci lities. Compared with the estimated respondent burden identified in the information col lection for the GHGRP currently approved by the Office of Management and Budget (OMB), this inf ormation collection will result in an overall increase in annual burden of 72,700 hours a nd $7.2 million, as shown in Section 6.Page 3 September 2015

2. NEED FOR AND USE OF THE COLLECTION

2(a) Need/Authority for the Collection
The FY2008 Consolidated Appropriations Act, signed into law on December 26, 2007, directed EPA to “develop and publish a draft rule n ot later than 9 months after the date of enactment of this Act, and a final rule not later t han 18 months after the date of enactment of this Act, to require mandatory reporting of greenhouse g as emissions above appropriate thresholds in all sectors of the economy of the United States.” As stated in the October 30, 2009 preamble to Part 98 (74 FR 56260), CAA section 114(a)(1) authorizes the Administrator to require e missions sources, persons subject to the CAA, or persons whom the Administrator believes may have necessary information to report emissions and provide such other information the Administrato r requests for the purposes of carrying out any provision of the CAA. Therefore, the EPA is finalizing this information c ollection under the authority provided
in CAA section 114.

2(b) Use /Users of the Data

The GHGRP collects information from facilities that directly emit GHGs and from suppliers of products that release GHGs if combuste d, oxidized, or used. The comprehensive GHG data reported directly from large facilities an d suppliers across the country are accessible to the public at: http://ghgdata.epa.gov/ghgp/main.do . Reporting entities generally use uniform methods for estimating emissions, which enables dat a to be compared and analyzed. Data collection in the GHGRP complements the Invent ory of U.S. Greenhouse Gas Emissions and Sinks (Inventory) and provides a crit ical tool for communities to identify nearby sources of GHGs and provide information to state an d local governments. The standardization of GHG data provides businesses with the necessary information to benchmark themselves against similar facilities, be tter understand their relative standing within their industry, and achieve and disseminate their e nvironmental achievements. Businesses and
other innovators can use the data to determine thei r GHG footprints, find cost- and fuel-savingPage 4 September 2015

efficiencies that reduce greenhouse gas emissions ( e.g., through energy audits or other forms of assistance), and foster technologies to protect pub lic health and the environment. Generally, the facility-specific GHG emissions data improve the understanding of the
factors that influence GHG emission rates as well a s the actions that facilities take to reduce emissions. The facility-based data can be aggregate d to the corporate level in order to track emission trends from industries, within industries, and across industries over time, particularly in response to policies and potential regulations. Specifically, subpart W data can be used to complem ent atmospheric GHG studies and inform updates to emission inventories. Various act ivity data are collected that can be used to improve understanding of the occurrence of emission s from a variety of sources.Page 5 September 2015

3. NONDUPLICATION, CONSULTATIONS AND OTHER COLLECTI ON
CRITERIA

3(a) Nonduplication

The information to be collected under the revisions includes 207 new data elements (refer to Appendix A for a list of these data elements). T hese new data elements consist primarily of quantities related to the activity level at the fac ility, emission factors used, characteristics of carbon-containing streams, and other process inform ation that would provide key information for verification, including confirming that emissions a re appropriate for a given activity level and estimating expected emissions based on data provide d. These new elements for subpart W are similar to the types of industry data already being collected under the GHGRP. The EPA has evaluated the types of industry data collected unde r Part 98, and concluded that they do not duplicate other information collections, as describ ed below. In developing the GHGRP, the EPA reviewed monitorin g methods, including:

• Federal programs within the United States, such as the Inventory, the U.S. Department of Energy’s (DOE’s) Energy Information A dministration’s (EIA’s) 1605b program, the Acid Rain Program, EPA Natural G as STAR Program, and voluntary GHG partnership programs;

• State and regional GHG reporting programs, such as The Climate Registry, the Regional Greenhouse Gas Initiative, the Western Reg ional Air Partnership, and programs in several states including California, Ne w Mexico, Connecticut, and New Jersey;

• Reporting protocols developed by nongovernmental or ganizations, such as the World Resources Institute/World Business Council for Sust ainable Development;

• Programs from industrial trade organizations, such as the Interstate Natural Gas Association of America’s GHG Emission Estimation Gu idelines, the American Petroleum Institute’s Compendium of GHG Estimation Methodologies for the Oil and Gas Industry, and the World Business Council for Su stainable Development’s Cement Sustainability Initiative’s CO 2 Accounting and Reporting Standard for the Cement Industry; and

• IPCC Guidelines for National Greenhouse Gas Invento ries.
Many of these programs collect different or additio nal data as compared to the GHGRP and this rulemaking. For example, state programs ma y include different data elements to supportPage 6 September 2015

other programs (e.g., offsets). While some programs collect similar information on GHG emissions, the Agency has determined that the GHGRP supplements and complements, rather than duplicates, existing programs’ data. Further, the EPA has made significant efforts over the past four years to facilitate reporting in the even t a single entity has to report at both the federal and state level. For example, the EPA has supported efforts by the California Air Resources Board to harmonize the reporting of information und er California’s Global Warming Solutions Act, AB32 with the EPA’s GHGRP. The product of the collaboration is referred to as California Electronic Greenhouse Gas Reporting Tool, or Cal e- GGRT. Documentation of the EPA’s review of GHG monitoring protocols used by federal and state voluntary and mandatory GHG programs as well as GHG reporting rules can be found in Docket ID No. EPA-HQ-OAR-2008-0508. For further dis cussion on the relationship of the GHGRP to other programs, please refer to the preamb les of each of the GHGRP rulemakings, the June 6, 2008 memorandum entitled “Review of Exi sting Programs” (Docket Item No. EPAHQ-OAR-2008-0508-0052), and the January 27, 2009 me morandum entitled “Review of Existing State Greenhouse Gas Reporting Rules” (Doc ket Item No. EPA-HQ-OAR-2008-0508- 0054). Some GHG programs are described below:

• A number of the EPA’s voluntary partnership program s include a GHG emissions and/or reductions reporting component (e.g., Natura l Gas STAR program, etc.). However, the GHGRP has much broader coverage than t he voluntary programs and therefore helps the EPA learn more about emissions from facilities not included in current programs.

• The EPA reviewed the Inventory, which is an annual comprehensive top-down assessment of national greenhouses gas emissions. W hile the Inventory is generally compiled from national surveys (i.e., not broken do wn at the geographic or facility level), the GHGRP focuses on bottom-up data from in dividual facilities that exceed appropriate thresholds.
As noted in the current ICR for the GHGRP, a number of programs at the state, tribal, territorial, and local level require emission sourc es in their respective jurisdictions to monitor and report GHG emissions. To reduce burden on reporters and program agencies, the Agency plans to share reported data, with the exception of any i nformation determined to be Confidential Business Information (CBI), with relevant agencies or approved entities using, where practical, shared tools, and infrastructure.Page 7 September 2015

Based on this evaluation, this information collecti on request does not duplicate other
information collections.

3(b) Public Notice Required Prior to Information Co llection Request (ICR) Submissions to OMB
A public notice of this collection is provided in t he Federal Register notice of “Greenhouse Gas Reporting Rule: 2015 Revisions and Confidentiality Determinations for Petroleum and Natural Gas Systems; Final Rule.”

3(c) Consultations
Early in the development process of the GHGRP, the EPA conducted a proactive communications outreach program to inform the publi c about the rule development effort. The EPA solicited input and maintained an open-door pol icy for those interested in discussing the rulemaking. Since January 2008, the EPA staff has h eld more than 100 meetings with stakeholders, including the following:

• Trade associations and firms in potentially affecte d industries/sectors;

• State, local, and tribal environmental control agen cies and regional air quality planning organizations;

• State and regional organizations already involved i n GHG emissions reporting, such as The Climate Registry, California Air Resources B oard, and the Western Climate Initiative; and

• Environmental groups and other nongovernmental orga nizations.
The EPA also has met with federal agencies, includi ng the U.S. Department of Energy and the U.S. Department of Agriculture, which have programs relevant to GHG emissions. On April 10, 2009 (74 FR 16448), the EPA proposed t he GHGRP. The EPA held two public hearings, and received more than 16,000 writ ten comments during the public comment period, which ended on June 9, 2009. Comments relat ed to Subpart W were received from more than 80 entities with over 1,200 pages of comments, recommendations, and alternatives for consideration. Details about these meetings and the responses to comments are available in Docket ID No. EPA-HQ-OAR-2009-0923. Following promu lgation of the final subpart W rulePage 8 September 2015

(75 FR 74458, November 30, 2010), the EPA finalized actions revising subpart W (76 FR 22825, April 25, 2011; 76 FR 59533, September 27, 2011; 76 FR 80554, December 23, 2011; 77 FR 51477, August 24, 2012; 78 FR 25392, May 1, 2013; 7 8 FR 71904, November 29, 2013; 79 FR 63750, October 24, 2014; and 79 FR 70352, November 25, 2014). In the current action, the EPA is revising certain petroleum and natural gas systems source category GHG reporting requirements. This ac tion is adding reporting requirements for two new industry segments (Onshore Natural Gas Tran smission Pipelines and Onshore Petroleum and Natural Gas Gathering and Boosting), adding reporting requirements for completions and workovers of oil wells with hydraul ic fracturing, and adding requirements to report well identification numbers related specific ally to wells for certain sources. In conjunction with this action, we are finalizing confidentiality determinations for the
new data elements contained in these amendments.

3(d) Effects of Less Frequent Collection
The frequency for reporting emissions information t o the EPA under the GHGRP was originally established to minimize the burden on ow ners and operators of affected facilities, while ensuring that the GHGRP collects facility-spe cific data of sufficient quality to achieve the Agency’s objectives. The GHGRP requires annual repo rting, except for a limited number of facilities that are already subject to more frequen t reporting requirements. This reporting frequency remains the same in these revisions to Pa rt 98. Annual reporting will ensure that data are verified and made available to the public, as authorized by the CAA. If the information collectio n were not carried out on this schedule, the Agency would not be able to develop an informed tra cking system of trends in GHG emissions across the country.

3(e) General Guidelines This collection is consistent with all OMB guidelin es under 5 CFR 1320.5.Page 9 September 2015

3(f) Confidentiality

Data collected under the GHGRP must be made availab le to the public unless the data qualify for CBI treatment under the CAA and EPA reg ulations. The CAA precludes “emission data” from being treated as confidential. For data reported under the CAA that are not emission data, the EPA typically makes CBI determinations un der 40 CFR 2.301 on a case-by-case basis. Due to the large number of entities reporting under the GHGRP and the large number of data reporting elements, the EPA previously concluded th at case-by-case determinations would not result in timely release of emission and other non- CBI data (see proposed CBI rule, 75 FR 39094, July 7, 2010 39094 and final CBI rule, May 2 6, 2011, 76 FR 30782). For this reason, the EPA has made CBI determinations for most data repor ting elements through a series of rulemakings that specify which data reporting eleme nts in Part 98: (1) are CBI, (2) are non-CBI, and (3) are emission data (i.e., ineligible for CBI protection). All data determined by the EPA to be CBI are safeguarded in accordance with regulatio ns in 40 CFR Chapter 1, Part 2, Subpart B. The CBI determinations for subpart W data reporting elements (excluding data reporting elements used as inputs to emission calculations) w ere made in 77 FR 48072 (August 13, 2012) and 79 FR 70352 (November 25, 2014). In the current action, the EPA is finalizing confidentiality determinations for the new data ele ments contained in these amendments.

3(g) Sensitive Questions
The revisions to reporting or recordkeeping require ments in the revisions to Part 98 do not include sensitive questions.Page 10 September 2015

4. THE RESPONDENTS AND THE INFORMATION REQUESTED

The respondents in this information collection incl ude owners and operators of petroleum and natural gas systems facilities that must report their GHG emissions to the EPA to comply with subpart W of Part 98. This section provides a list of industry sectors that must comply with the rule, the data elements required of program par ticipants, and the activities in which participants must engage to collect, assess, calcul ate, and in some cases submit the required data
elements.

4(a) Respondents/North American Industrial Classifi cation System (NAICS) Codes
The revisions to Part 98 affect facilities subject to subpart W. Reporting facilities for subpart W include, but are not limited to, those op erating one or more units that exceed the CO 2 e threshold for the industry sectors listed below (an d listed in Table A-3 of 40 CFR 98.2(a)(1)). Industry sectors are listed by NAICS code in Table 1. The NAICS codes are not exhaustive, but rather provide a list of facilities likely to be af fected.

Table 1. NAICS codes for affected reporters Part and Subpart NAICS codes 40 CFR Part 98 W. Petroleum and Natural Gas Systems 486210 Pipeline transportation of natural gas. 221210 Natural gas distribution. 211111 Crude petroleum and natural gas extraction. 211112 Natural gas liquid extraction.

4(b) Information Requested
(i) Data Items. The EPA is adding 207 new data elem ents to the reporting requirements. Table 1 of Appendix A specifies each new data eleme nt that would be reported by industry segment. (ii) Respondent Activities. The owner or operator o f a facility that is subject to the subpart W reporting requirements must report total annual GHG emissions. The primary tasks that reporting program respondents perform include:Page 11 September 2015

1. Implementing and updating, as necessary, appropriat e monitoring plans for each affected source and each affected unit at a source, as applicable; 2. Conducting operation and maintenance activities ass ociated with the monitoring, including quality assurance activities; 3. Ensuring data quality, preparing annual reports of emissions data, and submitting these reports to the EPA; 4. Potentially responding to questions or error messag es from the EPA; and 5. Maintaining records for a minimum of three years.
Respondents that use CEMS also conduct tests to cer tify the operations of monitors, submit the results of these tests, and record emiss ion data (this activity generally is performed electronically). Reports must present the annual mass GHG emissions from each subpart W industry segment separately. Reporters are required to provi de emissions in metric tons of methane (CH 4 ),
CO 2 , and nitrous oxide (N 2 O) for some sources and in metric tons of CO 2 e for other sources. The calculations used to determine GHG emissions, the f requency at which those calculations are required, and the methods used to estimate missing data depend on the specific subpart W industry segment. (iii) Electronic Reporting. Respondents report all data electronically through the Electronic Greenhouse Gas Reporting Tool (e-GGRT). All new data elements will be reported in the same way. As the e-GGRT accounts are already es tablished, the only burden related to electronic reporting will be entering the data elem ents.Page 12 September 2015

5. THE INFORMATION COLLECTED -- AGENCY ACTIVITIES, COLLECTION METHODS, AND INFORMATION MANAGEMENT

5(a) Agency Activities
EPA Headquarters activities include the monitoring and verification of emission reports, database and software maintenance, communication an d outreach, and program evaluation. This ICR reflects an incremental agency burden for program operation activities, which include monitoring and verification of emission rep orts. Specifically, the additional burden for
the review of new data elements was estimated.

5(b) Collection Methodology and Management
To collect data currently reported under the GHGRP, the EPA previously established a central repository of inventory data for all respon dents called e-GGRT. Respondents report data electronically, and the EPA stores the data in the database. The e-GGRT system provides a user interface for entering the GHG data and also has an XML reporting schema that allows facilities to upload GHG data directly. Under the revisions to Part 98, facilities subject to subpart W listed in Section 4(a) would report the new data elements via e-GGRT. The e-GGRT system follows Agency standards for desi gn, security, data element and reporting format conformance, and accessibility. Th e EPA designed the system to minimize respondents’ burden by integrating the new reportin g requirements with existing data collection and data management systems, when feasible.

5(c) Small Entity Flexibility
This information collection will not have a signifi cant economic impact on a substantial number of small entities. As part of this rule pack age, the EPA conducted a screening assessment comparing compliance costs to onshore petroleum and natural gas production specific receipts data for establishments owned by small businesses. This ratio constitutes a “sales” test that computes the annualized compliance costs of this ru le as a percentage of sales and determines whether the ratio exceeds 1 percent. The cost-to-sa les ratios were constructed at the establishment level (average reporting program cost s per establishment/average establishmentPage 13 September 2015

receipts) for several business size ranges. This al lowed the EPA to account for receipt differences between establishments owned by large a nd small businesses and differences in small
business definitions across affected industries. The cost-to-sales ratios are less than 1 percent fo r all establishments, except the ratio for the 1–20 employee range for facilities in the Onsho re Petroleum and Natural Gas Production segment with NAICS code 213111, which is 1 percent, and the ratios for the 1–20 employee range for facilities in the Onshore Petroleum and N atural Gas Production and Onshore Petroleum and Natural Gas Gathering and Boosting segments wit h NAICS code 213112, which are greater than 1 percent but less than 2 percent. The petrole um and natural gas industry has a large number of enterprises, the majority of them in the 1–20 em ployee range. However, a large fraction of production comes from large corporations and not th ose enterprises with less than 20 employees. The smaller enterprises in most cases deal with ver y small operations (such as a single family owning a few production wells) that are unlikely to cross the 25,000 metric tons CO 2 e threshold considered for the rule. An exception to such a sce nario is a small (less than 20 employee) enterprise owning large operations but conducting n early all of its operations through contractors. This is not an uncommon practice in th e Onshore Petroleum and Natural Gas Production segment. Such enterprises, however, are a very small group among the almost 16,000 enterprises in the less than 20 employee category, and the EPA will cover them in the rule. Therefore, this rule will not have a significant ec onomic impact on a substantial number
of small entities.

5(d) Collection Schedule

All data elements under this information collection will be submitted on an annual basis as part of the respondent’s annual report required under Part 98.Page 14 September 2015

6. ESTIMATING THE BURDEN AND COST OF THE COLLECTION

This section presents the EPA’s estimates of the bu rden and costs to respondents
associated with the activities described in Section 4 as well as the federal burden hours and costs
associated with the activities described in Section 5(a). Section 6(a) provides estimates of burden (hours) for all respondent types. Section 6(b) cont ains estimates of respondent costs for the information collection. Section 6(c) summarizes fed eral burden and costs. Section 6(d) describes the respondent universe and the total burden and co st of this collection to respondents. Section 6(e) presents the bottom line burden and cost. Sect ion 6(f) provides reasons for any change in
burden. The burden statement for this information c ollection is in Section 6(g).

6(a) Estimating Respondent Burden
Respondent burden estimates are presented in Exhibi t 6.1. The EPA estimates that the
total annual burden to all affected entities is 95. 6 hours per year over the three years covered by this information collection. There are expected to be approximately 433 new reporters will become subject to subpart W as a result of these am endments. Exhibit 6.1 presents aggregate burden and burden by subpart W industry segment.

6(b) Estimating Respondent Costs

The EPA estimates that the total annual cost to all affected non-federal entities is approximately $29.2 million over the 3 years covere d by this information collection. Exhibit 6.1 presents aggregate costs and costs by subpart W ind ustry segment. For details of the EPA’s cost calculations, please see Appendix C and Appendix D. The information collection will result in an overall increase in annual burden of 72,700 hours a nd $7.2 million. This increase is split between the three subpart W industry segments as shown in E xhibit 6.2. (i) Estimating Labor Costs. Costs to respondents as sociated with this information collection include the cost of labor by facility st aff to meet the rule’s information collection requirements. To calculate labor costs, the EPA use d labor rates from the Bureau of LaborPage 15 September 2015

Statistics consistent with the ICRs associated with the GHGRP currently approved by OMB. 1 For all subpart W industry segments, the labor rate derivations are shown in Table 2. The labor rates for this ICR are: $121.72 for senior managers , $106.89 for middle managers, $78.29 for engineers, and $66.57 for technicians.

Burden estimates were calculated by assigning a lev el of effort for each new requirement in the rule, assigning each requirement to one or m ore of the labor categories above, estimating the number of units affected by each new requiremen t, determining how many reporters will be impacted under each segment, and multiplying by the appropriate labor rates.
In order to be consistent with the levels of effort used for the existing industry segments, all levels of effort were estimated using the Econo mic Impact Analysis from November 2010. 2 For details of the burden calculations, please see Appendix B. (ii) Estimating Capital and Operations and Maintena nce (O&M) Costs Related to Process Emissions. The amendments to subpart W assume that various capital and O&M costs will be

Climate Change Division. November 2010. Docket Item No. EPA-HQ-OAR-2009-0923-3601. Pages 4-23 through 4-28.Page 16 September 2015

required to comply with the monitoring, recordkeepi ng, and reporting of process emissions
within this rule. Each new reporter was assumed to require a 4-drawer vertical file cabinet and an external hard drive for storing various records and electron ic data. The annualized capital cost for each reporter is $57 per year for a total of $24,700 per year. 3 During oil well completions and workovers with hydr aulic fracturing, there is a flowback period where the gas flow rate is monitored using a volumetric flow meter. These requirements affect approximately 50 new and 246 existing report ers in the Onshore Petroleum and Natural Gas Production industry segment. These reporters ar e assumed to purchase a volumetric flow meter at a cost of $585 per year ($2,400 annualized over 5 years at 7% interest). 4 The total cost is approximately $173,000 per year. The final capital and O&M cost impacts are related to travel costs. For Onshore Petroleum and Natural Gas Gathering and Boosting fa cilities, the size of a facility was assumed to encompass a much larger geographic area than a r elatively compact producing field or a gas processing plant. In order to account for emissions measurement across a larger area, travel costs were included and assumed to consist of 14 overnigh t trips per reporter per year. Assuming $150 per night and $100 per diem, 5 a cost of $3,500 per reporter per year was assumed . The total annual cost for travel is $700,000 per year. Due to the fact that compressor stations are unmann ed, pipeline throughput is continuously monitored and controlled and the engin eering data would be readily available to the reporters in the Onshore Natural Gas Transmission P ipeline segment. Therefore, reporters are assumed to perform engineering calculations based o n pressure, temperature, and volume of the pipeline segment rather than traveling to the compr essor stations to take measurements. The addition of oil well completions and workovers with hydraulic fracturing is not expected to impact any amount of travel that may be required of reporters in the Onshore Petroleum and Natural Gas Production segment.

(iii) Estimating Capital and O&M Costs Related to C ombustion Emissions. The amendments to subpart W that are included in this i nformation collection affect the combustionrelated capital and O&M costs for the Onshore Petro leum and Natural Gas Gathering and Boosting industry segment. For all other segments, the capital and O&M costs have not changed
from ICR Number 2300.15. For the Onshore Petroleum and Natural Gas Gathering and Boosting and Onshore Petroleum and Natural Gas Production segments, the capital and O&M costs associated with combustion emissions were based on the assumptions in ICR Number 2376.02, which included capital equipment costs of $3,500 (annualized over 10 years at 7% interest to $500 per year) and O&M costs of $1,700 per year. 6
There are no combustion sources at Onshore Natural Gas Transmission Pipeline facilities, so there are no increases to capital and O&M costs as a result of the subpart W amendments.

6(c) Estimating Agency Burden and Cost

This section describes the burden and cost to the f ederal government associated with this
information collection. Federal activities under th is information collection include EPA Headquarters oversight of the reporting program.

EPA burden and cost

The EPA activities associated with the mandatory GH G reporting rule include Headquarters oversight and implementation of the re porting program, e.g., monitoring and verification of emission reports, database and soft ware maintenance, communication and outreach, and program evaluation. The EPA estimates that, in implementing the two new industry segments under subpart W, Headquarters wil l incur an incremental burden of 1 full time equivalent (FTE). The total Agency cost is $544,648 , which is $109,000 higher than the previous ICR estimate of $436,000. To develop the EPA labor costs, the EPA estimates t he average hourly labor rate for salary and overhead and benefits for Agency staff t o be $52.37. To derive this figure, the EPA multiplied the hourly compensation at GS-12, Step 5 on the 2011 GS pay scale ($32.73) by the standard government benefits multiplication factor of 1.6 to account for overhead and benefits.

6(f) Reasons for Change in Burden

This rule will result in an overall increase in ann ual burden of 72,700 hours and $7.2 million. Specific respondent activities that impose an increase in burden and costs due to the EPA’s revisions to subpart W of Part 98 are identif ied below and reviewed in more detail in Appendix B. Reporting New Data Elements. For each of the 207 ne w data elements required to be reported (see Section 4(b)(i)), respondents would b e required to calculate the data element using readily available data, and submit the value via e- GGRT as part of the annual report currently required under Part 98. This revision is an increas e to burden and cost.Page 22 September 2015

Oil Wells with Hydraulic Fracturing. The EPA is add ing reporting requirements for completions and workovers of oil wells with hydraul ic fracturing. The provisions include the reporting of activity data on the number of wells f ractured and on the use of flaring and reduced emissions completions. This revision is an increase in burden and cost to the estimated 50 new reporters and 246 existing reporters containing oil wells with hydraulic fracturing, who would be reporting data elements that were not previously re quired. Onshore Petroleum and Natural Gas Gathering and Boo sting. The EPA is adding a new Onshore Petroleum and Natural Gas Gathering and Boo sting segment to subpart W. The requirements would require the reporting of GHG emi ssions from an entire gathering and boosting facility instead of the partial approach t hat currently exists under the GHGRP. Specifically, some gathering and boosting emission sources, such as natural gas compression stations, are only required to report GHG emissions if the facility exceeds the 25,000 metric tons
CO 2 e annual emission reporting threshold in subpart A, 40 CFR 98.2(a)(2), based on combustion emissions that are reported under subpart C. Subpar t W does currently require reporting from facilities that perform “natural gas processing” in 40 CFR 98.230(a)(3), but this requirement is only for those facilities that perform separation o f natural gas liquids or non-methane gases from produced natural gas or the separation of natural g as liquids into one or more component
mixtures and exceed 25 million standard cubic feet per day annual average daily gas throughput Due to these changes, the sources in this segment w ould include venting from natural gas pneumatic devices, natural gas driven pneumatic pum ps, storage tanks, reciprocating compressors, dehydrators, acid gas removal units, a nd centrifugal compressors; flare stacks; and leaks from gathering pipelines and components such as valves and connectors. Approximately 200 new reporters in this industry segment would ne ed to collect data, calculate, and report these
emissions under the revisions. This revision is an increase to burden and cost. Natural Gas Transmission Lines Between Compressor S tations. The EPA is adding reporting requirements for emissions from blowdowns of natural gas transmission pipelines in a new Onshore Natural Gas Transmission Pipeline segme nt in subpart W. The EPA is finalizing that reporters would use one of two methods to calc ulate or measure emissions from pipeline blowdown events. One method allows a reporter to ca lculate emissions based on the volume of the pipeline segment between isolation valves that is blown down and the pressure andPage 23 September 2015

temperature of the gas within the pipeline. The sec ond method allows the reporter to measure the emissions from the blowdown using a flow meter on t he blowdown vent stack. In both methods, approximately 150 new reporters would calculate bot h CH 4 and CO 2 emissions from the volume of natural gas vented using either default gas comp osition or engineering estimates of composition. This revision is an increase to burden and cost. Well Identification Numbers. The EPA is adding repo rting requirements for well identification numbers for wells in the onshore pet roleum and natural gas production. The well
identification number is either the US Well Number (formerly called the API Well Number), or if a US Well Number has not been assigned, a unique number assigned by the permitting authority. For reporters in the Onshore Petroleum a nd Natural Gas Production segment that report emissions using input data that are calculat ed from measurements at individual wells or equipment associated with individual wells the repo rter is required to report the well
identification number for which those measurements were made and the well identification number(s) of other wells to which the measurements will be applied. The EPA is not finalizing the proposed requirement that reporters in the Onsh ore Petroleum and Natural Gas Production segment report a list of well identification number s associated with different emission sources for all wells in a sub-basin included in the report ed emissions data. At proposal, the EPA assumed that well identificati on numbers were already collected. As a result of the comments received, the EPA reeva luated the proposal and agrees that the well ID requirements were more burdensome than initially intended. The final amendments represent numbers that are readily available and do not requi re any additional data gathering or calculation. The small additional burden needed to report the nu mbers in e-GGRT is included in the overall reporting burden estimate of 10 hours per reporter per year.

6(g) Burden Statement
The respondent reporting burden for this collection of information is estimated to average 317,100 hours and $29.2 million per year for a thre e-year period, where identical annual costs are anticipated for all three years. The average an nual burden to the EPA for this period is estimated to be 10,400 hours for oversight activiti es. The annual public reporting andPage 24 September 2015

recordkeeping burden for this collection of informa tion is estimated to average 95.6 hours per respondent. Burden means the total time, effort, or financial r esources expended by persons to generate, maintain, retain, or disclose or provide information to or for a federal agency. This includes the time needed to review instructions; de velop, acquire, install and utilize technology and systems for the purposes of collecting, validat ing and verifying information, processing and maintaining information and disclosing and providin g information; adjust the existing ways to comply with any previously applicable instructions and requirements; train personnel to respond to a collection of information; search data sources ; complete and review the collection of information; and transmit or otherwise disclose the information. An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a curr ently valid OMB control number. The OMB control numbers for the EPA’s regulations are liste d in 40 CFR part 9.
