# Oil and Natural Gas S ource Category Estimated Reasonably Available Emissions Control Technology Emission Reduction and Cost of Control **1 .**  **0 INTRODUCTION**  The Clean Air Act (CAA) provides that state implementation plans (SIPs) for ozone nonattainment (NA) areas must include reasonably available control technology (RACT) for sources of emissions , and stipulates that for moderate (and higher) ozone nonattainment (NA) areas, states must revise their SIPs to include RACT for each category of volatile organic compound (VOC ) sources covered b y control techniques guidelines (CTG). 1 

### Furthermore, the CAA requires that SIPs for states in ozone transport regions ( OTRs ) must comply with and implement RACT with respect to all sources of VOC in the state covered by a CTG . 2 

### The proposed Control Techniques Guidelines for the Oil and Natural Gas Source Category , henceforth the CTG, proposes recommendations for RACT for select emission sources in the oil and natural gas (ONG) source category . 3 

### The proposed CTG provides state, local and tribal air agencies (air agencies) with information to assist them in determining RACT for VOCs from select ONG source category emission sources. During the development of the guideline s , the EPA evaluated the sources of VOC emissions from the ONG source category and the available control approaches to reduce these emissions, including the costs of the evaluated approaches. The EPA is recommending RACT for compressors, natural gas - driven pneumatic controllers, natural gas - driven pneumatic pumps, storage vessels, equipment leaks at natural gas processing plants and fugitive emission s at well sites and compressor stations in the ONG s ource category . Table 1 - 1 presents a summary of the recommended RACT level of control for each of these sources . Air agencies can use the recommendations in the CTG to inform their own determination as to what constitutes RACT for VOC emissions for the ONG source category sources included in the CTG . The information contained in the CTG is provided only as guidance. The CTG does not change, or substitute for, requirements specified in applicable sections of the CAA or the EPA’s regulations; nor is it a regulation itself. The CTG does not impose any requirements on facilities in the ONG source category . It provides only recommendations for air agencies to consider when they

determine RACT. Air agencies are free to implement other technically- sound approaches that are consistent with the CAA and the EPA’s implementing regulations. To understand the potential impact of the CTG , the EPA conducted a scoping analys is based on a snapshot of the existing ONG s ource category . While the CTG itself does not require facilities in the ONG source category to adopt specific control technologies , assessing the emission reductions and costs of the case where recommended RACTs were adopted b y ONG sources in moderate and higher ozone NA areas and the OTR provides a reasonable basis for the impact of the RACT requirements ultimately determined by

air agencies. Therefore, this document present s an asse ssment of the emission reductions and net expenditures required b y the 1 CAA Section 172(c)(1) and Section 182(b)(2)(A) . 2 CAA Section 184(b)(1)(B) . 3 U.S. Environmental Protection Agency.

### s ource category in the case where all affected ONG sources that existed in 2012 adopt the recommended RACT. It is estimated that in this case VOC emissions would be reduced b y approximately

114,000 tpy

at an annualized net cost to the s ource category of approximately $ 206.8 million dollars based on the CTG recommended RACT. Additionally, the recommended RACT is estimated to reduce methane emissions by approximately 338,000 tpy

and hazardous air pollutants (HAP) b y 4,230 tpy . The assessment provides a reasonable estimate of the magnitude of expected emission reductions and net costs to the s ource category associated with the proposed CTG ; however there are limitations, including some that suggest the cost estimates may be conservative in some dimensions. For example, while the analys is attempts to include existing state regulations, the 2012 snapshot may

not fully account for state permit limits for individual sources that meet or exceed the recommended RACT level of control. Thus, the percentage of existing sources that are already achieving the recommended RACT level of control may be underestimated which would lead to fewer emission reductions and l ower expected cost s for owners and operators as a result of the CTG. Also, air agencies have the flexibility of determining RACT that may differ from what the EPA recommends. This flexibility allows them to potentially take advantage of their local conditions and implement a tailored RACT, which may lower the costs for sources in their jurisdiction. This analysis is based on s ource category averages and does not account for heterogeneity

in sources that affect the costs or emission reductions. The resulting state and local regulations may also require a lower level of control or may affect a lower number of sources than were included in the analys is presented here. The focus on a 2012 snapshot of existing sources may

include some sources that are no longer in use. However, any small changes to the existing universe of sources it is not expected to notably change the magnitude of the estimates in this analysis. The document is organized as follows:

 Section 2 presents a short discussion about the moderate or greater ozone NA and OTR are as impacted by

RACT.  Sections 3 presents a summary of the information used to determine the number of sources, baseline emissions , emission reductions and costs.  Section 4 presents the methodology used to estimate baseline emissions, emission reductions and costs.  Section 5 presents a summary of the VOC RACT emission reductions and costs.***E.O. 12866 Review

This document is referred to in this document as the "2011 Gas Composition Memorandum". 8 

###  All of the calculations supporting the analys es in this document are included in the CTG docket in the form of spreadsheets. 2012 DI Desktop Data The EPA obtained well production data from the DI Desktop database dated February, 2014. 9 

### The DI Desktop data collected b y DrillingInfo. Inc. consists of oil and natural gas well information that provides parameters describing the location, operator, and producti on characteristics. The DIDesktop data extract from the DrillingInfo . Inc. database included the population of all wells with gas or hydrocarbon liquid production during 2010 to 2012 and with a recorded completion ye ar of 2010 to the date of the extract (February, 2014). The 2012 DIDesktop data was queried to identify oil and natural gas wells in production in 2012 in RACT - impacted areas using Federal Information Processing Standards (FIPS) codes for the respective areas . Gas wells were defined as those wells with an average gas to liquids ratio greater than or equal to 100,000 standard cubic feet per barrel over the lifetime of the well, and oil wells were defined as those wells with an average gas to liquids ratio less than 100,000 standard cubic feet per barrel over the lifetime of the well. I f a well had liquids production but no gas production, it was classified as an oil well , and if a well had gas production but no liquids production, it was classified as a gas well. As a result of this analysis, 1 01,466 oil and gas wells (63,938 oil wells and 37,528 gas wells) were identified in moderate or greater ozone NA areas and 90,232 oil and gas wells (24,169 oil wells and 66,063 gas wells) were identified in OTR areas . An estimated 22,426 oil and gas wells (1,249 oil wells and 21,177 gas wells) were located in OTR areas that were also located in moderate or greater ozone NA areas. States that had wells with RACT - impacted areas include California, Maryland, Montana, New York, Pennsylvania, Texas and Virginia. This information was used to:  estimate the number and location of wells and well sites in OTR and moderate or greater ozone NA areas (as noted) ,  estimate the number and location of storage vessels in OTR and moderate or greater ozone NA areas (assuming one storage vessel per well 10

The DrillingInfo database is focused on historical oil and gas production data and drilling permit data. 10 The EPA is aware that there is often more than one storage vessel per well site. However, for emissions calculation purposes, we assumed that all storage vessels are likely manifolded together or could reasonable be manifolded together such that there is a single emission point for all storage vessels on the well site. Thus, we count one storage vessel per well site for emission calculation purposes because only one emission point would need to be controlled.***E.O. 12866 Review

OGJ Worldwide Gas Processing Survey (Capacities as of January 1, 2013, and Average Production) The OGJ Gas Processing Survey reflecting capacities as of January 1, 2013 (which would reflect capacities for 2012) was used to obtain location information of natural gas processing plants in OTR and moderate or greater ozone NA areas. Of the estimate d 606 natural gas processing plants in the U.S., an estimated 10 natural gas processing plants were located in OTR areas and 40 were located in moderate or greater ozone NA areas. None of the 40 natural gas processing plants in moderate or greater ozone NA areas were located in OTR areas. States that had processing plants with RACT - impacted areas include California, Pennsylvania and Texas. This information was used to:  estimate the number and location of natural gas processing plants in OTR and moderate or greater ozone NA areas,  estimate the number of processing segment compressors and pneumatic controllers located in OTR and moderate or greater ozone NA areas (using the percentage of the number of gas processing plants located in OTR and moderate or greater ozone NA areas ), and  estimate the number of gathering and boosting stations located in OTR and moderate or greater ozone NA areas (using the average of the percentage of well s and the percentage of gas processing plants lo cated in OTR and moderate or greater ozone NA areas ). **4 METHOD**  **OLOGY USED TO ESTIMATE RACT**  **- IMPACTED AREA**  **BASELINE EMIS**  **S I**  **ONS, EMISSION REDUTIONS AND COSTS** The following paragraphs present the methodologies used to estimate RACT - impacted area baseline emissions, emission reductions and costs for storage vessels, pneumatic controllers, pneumatic pumps, compressors, equipment leaks at natural gas processing plants and fugitive emissions at well sites and compressor stations . **4 .1**  **Storage Vessels** 4.1.1 Approach RACT - impacte d baseline emis sions and emission reductions from storage vessels were calculated b y multiplying the number of estimated uncontrolled storage vessels by emission***E.O. 12866 Review

-Impacted Natural Gas -Driven Pneumatic Controller Baseline Emissions, Emission Reductions and Costs RACT - impacted natural gas - driven pneumatic controller b aseline emissions were estimated by

multiplying the population of natural gas - driven pneumatic controllers and the VOC , methane and HAP baseline emissions per natural gas - driven pneumatic controller . Using the cost and emission reductions developed for the CTG, we estimated emission reductions and costs by multiplying the number of natural gas - driven pneumatic controllers by the emission reductions and costs per natural gas - driven controller. For processing segment natural gas - driven pneumatic controllers , we used the emission reductions and costs associated with the use of an existing instrument air system . For production segment natural gas - driven pneumatic controllers, we used the emission reductions and costs associated with the replacement of an existing high bleed controller with a low bleed controller. Using methane to HAP ratios developed for the ONG s ector as presented in the 2011 Gas Composition memorandum, we estimated RACT impacted natural gas - driven pneumatic controller HAP baseline emissions and emission reductions .

### 4 **. 3**  **Natural Gas -** **Driven Pneumatic Pumps**  4. 3 .1 Approach RACT - impacted natural gas - driven pneumatic pump baseline emis sions and emission reductions were calculated by multiplying the number of uncontrolled natural gas - driven pneumatic pumps reported in the 2012 GHG Inventory (assuming they were all natural gas driven pumps) by emissions and emission reductions per pump . The RACT - impacted natural gas - driven pneumatic pump costs were estimated by multiplying the calculated RACT VOC emission reductions by costs per pump. 4. 3 .2 RACT

-Impacted Popu lation ofNatural Gas -Driven Pneumatic Pumps Based on information in the 2012 GHG Inventory for oil production, there were an estimated 14,408 diaphragm pump s and 14, 293 piston pumps . The number of pneumatic pumps rep orted in the 2012 GHG Inventory for gas production was an estimated 37,477 pneumatic pump s (for both diaphragm and piston pumps ) . Similar to the assumption used in the 2015 NSPS TSD , we assumed that 50 percent of the gas production inventory pumps to be di aphragm pumps and 50 percent of the pumps to be piston pumps. Based on these assumption s , and assuming that all of the reported pumps were natural gas - driven, we estimated that there were 33, 147 diaphragm and 33,031 piston natural gas - driven pneumatic pump s in the production segment nationally . The percentage of RACT - impacted well s based on 2012 DI Desktop location information was used to estimate the number of RACT - impacted high bleed natural gas - driven pneumatic controllers . The 2012 GHG Inventory did not estimate emissions from pneumatic pumps for the natural gas processing segment.

### This attachment presents an analys is of state regulations that estimates the number of existing storage vessels that are already subject to a RACT - equivalent or greater level of control. The number of storage vessels determined to be subject to a RACT - equivalent or greater level of control was subtracted from the number of storage vessels that were located in RACT - impacted areas that were assumed to emit greater than or equal to six tons per year. There are likely more storage vessels regulated or permitted at or greater than the level of control of the recommended RACT that have not been accounted for in this analysis (e.g., based on case -by- case permit limits).***E.O. 12866 Review
