The approach for calculating emissions for natural gas systems generally involves the application of emission factors to activity data. For many sources, the approach uses technology-specific emission factors or emission factors that vary over time and take into account changes to technologies and practices, which are used to calculate net emissions directly. For others, the approach uses what are considered “potential methane factors” and reduction data to calculate net emissions. 3-74 DRAFT Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990–2015

A primary basis for estimates of CH 4 and non-combustion-related CO 2 emissions from the U.S. natural gas industry is a detailed study by the Gas Research Institute (GRI) and EPA (EPA/GRI 1996). The EPA/GRI study developed over 80 CH 4 emission factors to characterize emissions from the various components within the operating stages of the U.S. natural gas system. The EPA/GRI study was based on a combination of process engineering studies, collection of activity data, and measurements at representative gas facilities conducted in the early 1990s. Methane compositions from the Gas Technology Institute (GTI, formerly GRI) Unconventional Natural Gas and Gas Composition Databases (GTI 2001) are adjusted year to year using gross production for oil and gas supply National Energy Modeling System (NEMS) regions from the EIA. Therefore, emission factors may vary from year to year due to slight changes in the CH 4 composition for each NEMS oil and gas supply module region. The emission factors used to estimate CH 4 were also used to calculate non-combustion CO 2 emissions. Data from GTI 2001 were used to adapt the CH 4 emission factors into non-combustion related CO 2 emission factors. Additional information about CO 2 content in transmission quality natural gas was obtained from numerous U.S. transmission companies to help further develop the non-combustion CO 2 emission factors. Another key source of emission factors is the Greenhouse Gas Reporting Program (GHGRP) Subpart W data (EPA 2016). In the production segment, GHGRP data were used to develop emission factors for gas well completions and workovers (refracturing) with hydraulic fracturing, pneumatic controllers and chemical injection pumps, condensate tanks, and liquids unloading. In the processing segment, GHGRP data were used to develop emission factors for fugitives, compressors, flares, dehydrators, and blowdowns/venting. In the transmission and storage segment, GHGRP data were used to develop factors for pneumatic controllers. Other data sources used for emission factors include Marchese et al. for gathering stations, Zimmerle et al. for transmission and storage station fugitives and compressors, and Lamb et al. for pipelines. See Annex 3.6 for more detailed information on the methodology and data used to calculate CH 4 and noncombustion CO 2 emissions from natural gas systems. Activity Data. Activity data were taken from the following sources: DrillingInfo, Inc (DrillingInfo 2016); American Gas Association (AGA 1991 through 1998); Bureau of Ocean Energy Management, Regulation and Enforcement (previous Minerals and Management Service) (BOEMRE 2011a, 2011b, 2011c, 2011d); Natural Gas Liquids Reserves Report (EIA 2005); Natural Gas Monthly (EIA 2016a, 2016b, 2016c); the Natural Gas STAR Program annual emissions savings (EPA 2013c); Oil and Gas Journal (OGJ 1997 through 2015); Pipeline and Hazardous Materials Safety Administration (PHMSA 2016a, 2016b); Federal Energy Regulatory Commission (FERC 2015); Greenhouse Gas Reporting Program (EPA 2016); other Energy Information Administration data and publications (EIA 2001, 2004, 2012, 2014); (EPA 1999); Conservation Commission (Wyoming 2015); and the Alabama State Oil and Gas Board (Alabama 2015). For a few sources, recent direct activity data are not available. For these sources, either 2014 data was used as a proxy for 2015 data, or a set of industry activity data drivers was developed and used to calculate activity data over the time series. Drivers include statistics on gas production, number of wells, system throughput, miles of various kinds of pipe, and other statistics that characterize the changes in the U.S. natural gas system infrastructure and operations. More information on activity data and drivers is available in Annex 3.6. Calculating Net Emissions. For most sources, emissions are calculated directly by applying emission factors to activity data. However, for certain sectors, some sources are calculated using potential emission factors, and the step of deducting CH 4 that is not emitted from the total CH 4 potential estimates to develop net CH 4 emissions is applied. To take into account use of such technologies, data, where available, are collected on both regulatory and voluntary reductions. Regulatory actions addressed using this method include National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations for dehydrator vents. Voluntary reductions included in the GHG Inventory are those reported to Natural Gas STAR. In this public review draft of the Inventory, EPA included an emissions estimate from the Aliso Canyon leak event. 80 EPA used the estimate of the leak published by the California Air Resources Board (99,650 MT for the 80 For more information on the Aliso Canyon event, and the measurements conducted of the leak, please see Ensuring Safe and Reliable Underground Natural Gas Storage, Final Report of the Interagency Task Force on Natural Gas Storage Safety, available Energy 3-75
