                      PART A OF THE SUPPORTING STATEMENT 
           INFORMATION COLLECTION EFFORT FOR OIL AND GAS FACILITIES 
1.	Identification of the Information Collection
1(a)	Title of the Information Collection 
"Information Collection Effort for Oil and Gas Facilities." This is a new Information Collection Request (ICR).
1(b)	Short Characterization 
      This information collection is being conducted by the U.S. Environmental Protection Agency's (EPA's) Office of Air and Radiation (OAR) pursuant to section 114 of the Clean Air Act, as amended ("CAA" or "the Act"), to assist the Administrator of EPA in developing emissions standards for oil and gas facilities pursuant to section 111 of the Act.  Section 114(a) states, in pertinent part:
     For the purpose...(iii) carrying out any provision of this Chapter...(1) the Administrator may require any person who owns or operates any emission source...to-. . .(D) sample such emissions (in accordance with such procedures or methods, at such locations, at such intervals, during such periods and in such manner as the Administrator shall prescribe); (E) keep records on control equipment parameters, production variables or other indirect data when direct monitoring of emissions is impractical.. .(G) provide such other information as the Administrator may reasonably require...
      The non-confidential information submitted in response to this information collection will be made available to the public. 	
      In January 2015, as part of the Obama Administration's commitment to addressing climate change, the EPA outlined a number of steps it plans to take to address methane and smog-forming volatile organic compound (VOC) emissions from the oil and gas industry, in order to ensure continued, safe and responsible growth in U.S. oil and natural gas production. As a result, EPA proposed and finalized New Source Performance Standards for the oil and gas industry to achieve both methane reductions and additional reductions in volatile organic compounds (VOCs). The EPA has also committed to develop standards of performance for existing oil and gas sources. This information collection request is necessary to develop nationally applicable regulations to reduce methane emissions from oil and gas sources.
      The oil and gas industry includes a wide range of different types of facilities or industry segments. The oil and gas industry segments considered in the framework of this information collection request include, but are not necessarily limited to: onshore petroleum and natural gas production; onshore petroleum and natural gas gathering and boosting; onshore natural gas processing; onshore natural gas transmission compression; onshore natural gas transmission pipelines; underground natural gas storage; LNG storage; and LNG import and export equipment. It is estimated that there are almost 1.4 million producing oil and gas wells at approximately 698,800 well sites (onshore production facilities) in the United States (U.S.). There are approximately 5,000 gathering and boosting facilities, 668 processing facilities, 1,400 transmission compression facilities, 939 transmission pipeline facilities, 418 underground natural gas storage facilities, and 111 liquefied natural gas (LNG) storage or import/export facilities.
      Information on greenhouse gas (GHG) emissions from oil and gas facilities is collected as part of the EPA's Greenhouse Gas Reporting Program (GHGRP) under 40 CFR Part 98 Subpart W, Petroleum and Natural Gas Systems. However, there is a reporting threshold, and the reporting requirements do not currently cover certain emission sources (i.e., gathering and boosting and transmission pipelines facilities; these industry segments will begin to report emissions in 2017 for emissions occurring in the 2016 calendar year), and therefore the data do not represent the entire universe of emissions from oil and gas systems. The GHGRP also aggregates production level reporting at a basin level. Further, the GHGRP does not collect information on design, performance, and costs of mitigation measures. This information is necessary to evaluate the scope, design, and potential impacts of future regulation of this industry, in particular, of methane emissions from existing oil and gas facility sources.   
      There will be two parts to the information collection that will be issued simultaneously. Part 1, referred to as the operator survey, is specifically designed to obtain comprehensive information from onshore petroleum and natural gas production facilities to better understand the number and types of equipment at production facilities. Part 1 seeks to collect information regarding production operators (e.g., facility name, address and contact information) as well as information on the location and types of equipment (e.g., number of wells, tanks, dehydrators and compressors) present at well surface sites and centralized production surface sites. The definitions of well surface sites and centralized production surface sites are expected to align with the definition of facility commonly employed when permitting new and existing sources. Part 1 will be sent to all known operators of oil and gas production wells and will allow the Agency to obtain the information necessary to identify and categorize all potentially affected oil and gas production facilities. The operators will complete the Part 1 survey and provide equipment counts for all production facilities that they operate except for facilities selected to complete Part 2. Part 1 is not expected to contain any confidential business information. This operator survey may be submitted either electronically or through hard copy responses. The submission requires the owner or operator to certify that the information being provided is accurate and complete.
      Part 2, referred to as the detailed facility survey, will be sent to selected oil and gas facilities (production, gathering and boosting, processing, compression/transmission, pipeline, natural gas storage, and LNG storage and import/export facilities) based on statistical sampling method described in Part B of this Supporting Statement. Part 2 will collect detailed, unit-specific information on emission sources at the facility and any emission control devices or management practices used to reduce emissions. Most of the information requested under Part 2 is expected to be available from company records and would not require additional measurements to be performed. However, selected data elements must be completed based on actual component equipment counts (specifically, pneumatic device counts and equipment leak component counts) or measurement data (specifically, separator/storage vessel flash analyses). If this information is not directly available for a facility, the respondent must collect and report this information (count equipment components and/or sample and analyze tank feed streams) as part of this information collection. Part 2 is expected to include information that oil and gas facilities consider to be confidential and the survey must be completed and submitted electronically via the EPA's Electronic Greenhouse Gas Reporting Tool (e-GGRT).
The EPA estimates the cost of Part 1 and Part 2 of the information collection will be 245,481 hours and $37,692,625. 
2.	Need for and Use of the Collection 
2(a)	Need/Authority for the Collection 
      Collectively, oil and gas facilities are the largest industrial emitters of methane in the U.S. In January 2015, as part of the Obama Administration's commitment to addressing climate change, the EPA outlined a number of steps it plans to take to address methane and smog-forming volatile organic compound (VOC) emissions from the oil and gas industry. The EPA has recently promulgated new source performance standards (NSPS) for the oil and gas industry to achieve both methane reductions and additional reductions in VOCs (40 CFR part 60, subpart OOOOa; see 81 FR 35824). The EPA is also now beginning the process of development of standards of performance for existing oil and gas sources. Section 111(d) of the Act provides a cooperative federalism approach to establishing standards of performance for existing sources. Under this approach, EPA establishes guidelines that identify the emission performance states must require their sources to achieve, and states then submit plans for EPA review and approval, which establish standards of performance that achieve that emissions performance.  
      Currently available information for oil and gas facilities is incomplete to assess what may be the best approach for regulating these sources. As noted previously, the EPA collects information on the GHG emissions from oil and gas facilities under Subpart W of the GHGRP. However, the GHGRP does not collect information on costs or technical feasibility of mitigation measures. This information is necessary to evaluate the scope and potential impact and design of future standards of performance for oil and gas facility sources, both for existing sources and sources not covered by the standards for performance for new and modified sources. There are also differences in the definition of "facility" in the GHGRP for the oil and gas production facilities as compared to the way we have defined facility under our NSPS regulations. Additionally, certain states have moved forward with their own rules and have developed information needed for their own purposes, but this information is not sufficient for a national rulemaking. Thus, it is necessary to collect specific information for oil and gas production facilities to understand the number of affected facilities and to assess potential alternative regulatory approaches for existing sources.
 2(b)	Use/Users of the Data 
The data collected from Parts 1 and 2 will be used to determine the number of potentially affected emission sources the types and prevalence of emission controls or emission reduction measures used for these sources at oil and gas facilities nationwide, and potential costs for those measures and controls. Due to the large number of potentially affected sources in most of the industry sectors, a statistically significant number of facilities from each sector will be surveyed to collect this information and fill data gaps for setting emission limits and evaluating the emission impacts of various regulatory options for standards of performance for oil and gas facilities. 
3.	Non-duplication, Consultations, and Other Collection Criteria 
3(a)	Non-duplication 
      The Agency recognizes that some of the information requested may already be included in the submittals being made by individual companies to the GHGRP. Therefore, the Agency reviewed each survey question to determine if the information is already included in the GHGRP. Where the information requested is identical to that collected under the GHGRP, facilities that report under the GHGRP are only required to provide their GHGRP ID number and may skip the questions that are duplications of information being reported under the GHGRP. However, a production facility under the GHGRP includes all wells owned or operated by a person within a single basin, which may include properties that are not contiguous or adjacent. While some of the production information is reported at the sub-basin level under the GHGRP, this information is still expected to be an aggregation of the production across numerous affected facilities. In these cases, the reporting of sub-basin level information under the GHGRP is not identical to reporting facility level production information under this ICR where respondents must provide the information at the facility level considering the CAA affected source definition (contiguous or adjacent properties under common ownership or control).  
      Some of the information requested may also be included in submittals by individual facilities pursuant to operating permit applications, state reporting requirements, or lease requirements. Even when the permit is available, often the unit-specific information is unavailable. Typically, the information requested under this electronic survey is not available in a consistent and usable format from these other sources.
3(b)	Public Notice Required Prior to ICR Submission to OMB 
This ICR is being submitted to the Office of Management and Budget (OMB) as required by the Paperwork Reduction Act of 1995 (PRA) and the subsequent rule issued by the OMB on August 29, 1995 (60 FR 44978).  The Agency previously submitted the draft ICR for public review, and the ICR being submitted to the OMB includes revisions to address the public comments received during that review period.
3(c)	Consultations 
The Agency worked with EPA Regional Offices and State delegated authorities to understand data needs and to solicit comment on the questions to be included in the draft ICR. The Agency also conducted a number of webinars for environmental groups, industry representatives and state agencies to inform various stakeholders regarding the planned ICR. Initial feedback that was received from these efforts was considered in the development of the draft ICR. In addition, as noted previously, the public had an opportunity to provide detailed comments on the draft ICR. During this period, the EPA met with several different stakeholders to further discuss their comments on the ICR. The EPA has considered and addressed those comments, as appropriate, through revisions in the ICR. A summary of the comments and EPA's responses is located in Docket ID No. EPA-HQ-OAR-2016-0204. Docket ID No. EPA-HQ-OAR-2016-0204 also includes meeting minutes for the various meeting held with stakeholders.
3(d)	Effects of Less Frequent Collection 
      This ICR is a one-time information collection. Part 1 will require the owner/operator of each potentially affected oil and gas production facility to complete a short survey of the numbers of wells, separators, storage tanks, and compressors at each centralized production surface site and each well surface site. This information is critical to understanding the universe of existing facilities and the impacts of the rule for existing sources. Part 2 employs a statistically-based sampling approach to collect unit-specific operation and control system information. This information is needed to understand the types of control systems used at existing facilities, the prevalence of use, costs, and the emissions reductions that can be achieved through alternative regulatory strategies for existing sources. 
      Because this is a one-time information collection, the Agency could not consider less frequent information collection. However, in order to reduce the overall burden of the ICR, the Agency is proposing a statistically-based sampling approach for Part 2. The Agency considered the accuracy of the industry characterization of processing units and controls obtained from the survey needed to make informed decisions. The Agency considered sampling approaches based on acceptable error margins. While the Agency would prefer to have the smallest error possible, reducing the acceptable error margin increases the number of facilities that would need to be included in the sampling survey. After evaluating the impacts of sampling approaches, the Agency developed the sampling approach described in Appendix B based on acceptable error margins. Surveying fewer facilities in the sampling approach would increase the error associated with data evaluations conducted using the collected data and could result in the Agency making incorrect conclusions based the uncertainty associated with a more limited data set. 
3(e)	General Guidelines 
This ICR will adhere to the guidelines for Federal data requestors, as provided at 5 CFR 1320.6.
3(f)	 Confidentiality  	
      Respondents will be required to respond under the authority of section 114 of the Act.   All information submitted to the Agency in response to the ICR surveys will be managed in accordance with applicable laws and EPA's regulations governing treatment of confidential business information at 40 CFR Part 2, Subpart B.  Any information determined to constitute a trade secret will be protected under 18 U.S.C. § 1905.   
3(g)	Sensitive questions
This section is not applicable because this ICR will not involve matters of a sensitive nature.
4.	The Respondents and the Information Requested
4(a)	Respondents/NAICS Codes 
Respondents affected by this action are owners/operators of oil and gas facilities. There are several industry segments that may be considered oil and gas facilities. This ICR is specifically requesting information for facilities in the following industry segments:  onshore petroleum and natural gas production, onshore petroleum and natural gas gathering and boosting, onshore natural gas processing, onshore natural gas transmission compression, onshore natural gas transmission pipelines, underground natural gas storage, LNG storage, and LNG import and export equipment. The ICR is not requesting information for the offshore petroleum and natural gas production industry segment or the natural gas (local) distribution industry segment. Table 1 below presents some examples of potentially affected entities according to NAICS code. Table 1 is not intended to be exhaustive, but rather provides a guide for respondents regarding facilities likely to be affected by this ICR.

Table 1. Examples of Potentially Affected Entities by Category.

Pipeline transportation of natural gas.

Table B-1 in Part B of this Supporting Statement presents the Agency's best estimate of the number of potential affected facilities by industry segment. This information was derived based on review of information reported to the GHGRP, the Pipeline and Hazardous Materials Safety Administration (PHMSA), the Energy Information Administration (EIA), the National Emissions Inventory (NEI), Drilling Information Desktop (a subscription database of production wells), and other publically available information. 
4(b)	Information Requested
      (i)	Data items, including recordkeeping requirements.  Part 1 will collect corporate and operator-level contact information as well as equipment counts for key equipment (number of wells, tanks, separators, compressors, and dehydrators) at each centralized production surface site and each well surface site owned or operated by that operator. This information is expected to be readily available to the operator and no additional measurement of recordkeeping requirements are imposed. Part 2 will collect detailed unit-specific information on emission sources at selected facilities as well as information on emission controls or management practices used to reduce emissions at the selected facilities. A majority of the information requested under Part 2 is expected to be available from company records and would not require additional measurements to be performed. However, respondents will be required to collect and report detailed counts of pneumatic devices and equipment leak components if this information is not already available in the company records. Additionally, respondents of facilities that have separators or storage vessels will have to collect pressurized samples of liquid streams in order to perform a flash analyses if these analyses are not available. Except for these three data elements, all other information requested in the questionnaire is to be completed based on existing company records. The survey will also request submission of the recent emission measurements, if available, to further characterize the emission sources. These data elements are only required when measurement data are already available; respondents are not required to perform direct emission measurements (except for flash gas analysis) as a result of this information collection. 
 (ii)      Respondent activities. The activities a respondent will undertake to fulfill the
requirements of the information collection are presented in Attachments 3A and 3B. These include: i) read instructions; ii) compile requested information on each affected source based on existing data; iii) if necessary, visit the facility to perform required equipment counts and collect tank feed samples (Part 2 only); iv) if necessary, have the feed samples analyzed for flashing potential and composition of flash gas according to methods prescribed in the information collection (Part 2 only), and v) submit information to the EPA through electronic survey instrument. For Part 1 only, respondents also have the option of hard-copy submission.
5.	The Information Collected--Agency Activities, Collection Methodology, and Information Management
5(a)	Agency Activities 
A list of activities that will be required of EPA is provided in Attachment 4. These include: i) develop electronic questionnaire/reporting form; ii) answer respondent questions; and iii) review and analyze responses.
5(b)	Collection Methodology and Management
      In collecting and analyzing the information associated with this ICR, the EPA will use personal computers, Microsoft Excel(C) based reporting forms, and the e-GGRT reporting system.  The EPA will ensure the accuracy and completeness of the collected information by reviewing each submittal. The information collected pursuant to this ICR will be maintained in a computerized database on secure EPA servers. To better facilitate uniformity in the format of the reports that are received, and, thus, increase the ease of data review and analysis, standardized survey Excel spreadsheet reporting forms will be developed and distributed to respondents.
5(c)	Small Entity Flexibility 
      The Part 1 survey is required for all operators of oil and gas production facilities and all respondents to the Part 1 survey will be subject to the same requirements. The Part 2 survey employs a sampling approach of facilities in each industry segment, and facilities selected to complete the Part 2 survey will be subject to the same requirements. The EPA expects that a portion of the respondents to both Parts 1 and 2 may be small entities; however, any individual small entity would be expected to have fewer sources so its response burden will be minimized. In addition, the Agency has opted to use an electronic format for the questionnaire, which allows some automation in the form and response fields, to reduce the burden and improve the data accuracy from all respondents, including small entities. However, the information requested under Part 1 is limited, especially for small entities that are expected to have fewer wells and equipment to report. Therefore, we are allowing respondents to Part 1 the option to submit via hard-copy, which will eliminate the need to register the facility online prior to data submission. The survey will contain questions to determine the small entity status of a facility. These questions may help to identify, quantify, and minimize the burden on small entities during the rulemaking process.  
5(d)	Collection Schedule 
      The EPA anticipates issuing the 114 letters by October 30, 2016. These section 114 letters would require the owner/operator of an oil and gas facility to complete and submit the Part 1 survey within 30 days of receipt of the survey, and would require facilities to complete and submit the Part 2 survey with 120 days of receipt. 
6.	Estimating the Burden and Cost of the Collection 
6(a)	Estimating Respondent Burden 
The one-time burden estimate for reporting and recordkeeping requirements are presented in Attachments 3A and 3B. These numbers were derived from estimates based on the time needed to collect and enter the information required for each of the different forms included in the Part 1 and Part 2 surveys and the proportion of facilities in each industry segment that is expected to complete each form. These estimates represent the one-time burden that will be incurred by the recipients. These estimates are based on 15,000 respondents for Part 1 and 3,818 expected respondents to Part 2. In reality, the actual number of respondents to Part 1 may be less due to incorrect contact information so that not all questionnaires mailed out will be deliverable. 
6(b)	Estimating Respondent Costs 
Attachments 3A and 3B present estimated costs for the required recordkeeping and reporting activities.  Labor rates were based on May 2015 raw labor rates for the Mining: Oil and Gas Extraction Sector (NAICS 211000), loaded using an overhead factor of 110%, consistent with other ICRs. The resulting loaded hourly rates are $176.95 for management personnel, $148.95 for engineering personnel, $65.10 for plant operator personnel, and $47.08 for clerical personnel. These values were taken from the Bureau of Labor Statistics Occupational Employment Statistics Survey Web site and reflect the latest values available (May 2015).  
6(c)	Estimating Agency Burden and Cost
      The costs the Federal Government would incur are presented in Attachment 4. Labor rates and associated costs are based on the estimated 2015 loaded hourly rates (labor rate plus 60% for overhead) of $88.30 for management personnel (GS- 15, step 5); $53.42 for technical personnel (GS- 12, step 5); and $30.11 for clerical personnel (GS-7, step 5). These labor categories and burden estimates were selected to be consistent with other ICRs.
6(d)	Estimating the Respondent Universe and Total Burden and Costs 
      The potential respondent universe consists of approximately 15,000 operators for Part 1 representing approximately 698,800 facilities (based on total well counts assuming 2 wells per facility). Thus, the burden estimate for each operator is based on reporting information for approximately 50 facilities on average, with 2 wells per facility. Operators with wells that are selected for Part 2 will not be required to report information for the well surface sites that contain the selected wells in the Part 1 questionnaire. Furthermore, the Agency is estimating a 90 percent response rate to determine the number of Part 2 questionnaires to be mailed out to ensure a statistically significant number of responses are received and expects a similar response rate for the Part 1 survey. As the Part 1 survey is designed as a complete survey of all well operators, the respondent burden for Part 1 is conservatively estimated based on 15,000 respondents.
      Part 2, designed as a statistically based sampling survey of each of the industry segments, is described in greater detail in Part B of this Supporting Statement. Table B-3 in Part B of this Supporting Statement provides the total facility counts in each industry segment,  the number of responses needed, and the number of questionnaires to be mailed to ensure the desired number of responses are received. Thus, the Part 2 burden estimates are based on mailing out 4,259 Part 2 questionnaires and receiving 3,818 responses from industry respondents. Burden estimates were projected for each questionnaire form based on the number of sources expected to be at a typical facility when that source type is present. Additionally, not all source types will be present at certain types of facilities or at all facilities of a certain type. For example, well sites are only expected to be at production facilities and acid gas removal units may not be present at every production facility. Therefore, the fraction of facilities within a given industry segment that are expected to have a specific source type were also estimated in order to determine the number of respondents for each form. Table 2 summarizes the assumptions used to estimate the respondent burden for the Part 2 survey. 
6(e)	Bottom Line Burden Hours and Costs Tables 
(i)	Respondent tally. The total industry burden hours and costs, presented in Attachments 3A and 3B, are calculated by summing the person-hours column and by summing the cost column. The burden and cost to the industry is 245,481 hours and $37,692,625, which includes $6,987,000 in operation and maintenance (O&M) costs to cover postage and contracting services for storage vessel feed material flashing analyses.

6(g)	Burden Statement
Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, disclose, or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements; train personnel to be able 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 currently valid OMB control number. The OMB control numbers for EPA's regulations are listed in 40 CFR part 9 and 48 CFR chapter 15.
The total reporting and recordkeeping burden and cost to production operators for the Part 1 information collection is 116,438 hours and $16,468,682 (7.76 hours and $1,098 per respondent for 15,000 respondents). The total annual reporting and recordkeeping burden and cost to the industry for the Part 2 information collection is 129,043 hours and $21,223,943 (33.80 hours and $5,559 per respondent for 3,818 respondents). 
This ICR does not include any requirements that would cause the respondents to incur either capital or start-up costs. The EPA has assumed that all respondents will contract (i.e., purchase services/operation and maintenance costs) for the storage vessel feed material flashing analyses. In addition, there will be a small O&M costs for respondents electing to mail a hard copy of the Part 1 responses. These costs have been included in the burden estimate above. The resulting total burden for Part 1 and Part 2 of this information collection is 246,481 hours and $37,692,625, which includes $6,987,000 in O&M costs to cover mailing hard copies of Part 1 responses and contracting services for storage vessel feed material flashing analyses.

           INFORMATION COLLECTION EFFORT FOR OIL AND GAS FACILITIES
                                       
1.	Respondent Universe 
This ICR will collect information from oil and gas industry sectors including facilities associated with production, processing, transmission, and storage of oil and natural gas. This ICR is specific to onshore operations and does not include offshore oil and gas production facilities. This ICR also does not include local gas distribution facilities as these facilities are regulated under separate authority. Thus, this ICR covers the following industry segments within the oil and gas industry: onshore petroleum and natural gas production; onshore petroleum and natural gas gathering and boosting; onshore natural gas processing; onshore natural gas transmission compression; onshore natural gas transmission pipelines; underground natural gas storage; LNG storage; and LNG import and export equipment. 
2.	Respondent Universe Stratification 
      As noted previously, there are numerous types of oil and gas facilities, which are referred to as industry segments. Table B-1 provides a listing of the oil and gas facility industry segments that this ICR will examine and the number of facilities expected to be included in each industry segment.

PHMSA = Pipeline and Hazardous Materials Safety Administration 
EIA = Energy Information Administration
      Each industry segments is considered to have unique characteristics and, therefore, each industry segment is considered to be a different population for statistical sampling. The Agency also considers that the representation of the production segment should be further stratified, for the purpose of this ICR, based on differences in the type of well (oil or natural gas, production rates and gas-to-oil ratio), the type of formation, and the production basin. The Agency proposed two options for establishing different populations within the production segment: one based on the well type using GOR ranges and one based on regional groupings of basins. After a review of the comments received, we are proceeding with the GOR groupings, but we are adding a subpopulations for "stripper wells," which are wells that produce 15 barrels of oil equivalence (BOE) per day or less. Comments indicated that these wells generally make up about 80 percent of the total number of wells but only contribute about 10 percent of the crude oil and natural gas produced in the United States.[,]  Table B-2 provides a summary of the populations to be considered in the production segment.

[1]Facility count is based on number of wells assuming 2 wells per facility, based on NSPS OOOOa Technical Support Document, Docket Item EPA-HQ-OAR-2010-0505-5120.3.	Sample Size 
      A key consideration in survey design is determining how large a sample is needed for the estimates obtained from that sample to be statistically reliable enough to meet the objectives of the study. In general, the estimates are considered statistically reliable if they meet the criteria for desired levels of accuracy and precision. Accordingly, while determining sample sizes for the facility populations shown in Tables B-1 and B-2, we considered desired levels of accuracy and precision for the estimates to be obtained from survey sampling. 
      The type of question, the desired margin of error, and the specified confidence level are the key factors for determining sample sizes to ensure that estimates have desired levels of accuracy. In general, two types of questions are included in a survey: fixed response questions (yes/no questions, for which a proportion of respondents may be estimated) and numeric value questions (from which an average (mean) value may be estimated). The necessary sample size when there is an infinite population size (n_o) may be determined as follows:
      n_o = px(1-p)x(z/error)[2] 	when the objective is estimation of a proportion
          n_o = (txs/error)[2] 	when the objective is estimation of a mean
where, 
	p =	expected proportion of a given outcome, typically assumed to be 0.5 as this maximizes px(1-p).
	z =	z-statistic based on desired confidence level.
	error =	acceptable margin of error.
	t =	t-statistic based on desired confidence level and expected population size. Same as z-statistic for population sizes greater than 30.
	s =	the standard deviation of the estimate.
      For fixed response questions (estimation of a proportion), the Agency has selected a 95 percent 2-sided confidence level (z = 1.96) and a 5 percent margin of error (error = 0.05). The Agency considers these selections adequate to assure the objectives of the ICR will be met for proportional response questions for the key populations (i.e., the non-stripper well GOR populations and all other non-production populations). Therefore, the projected sample size needed for questions with proportional objectives is 385 [i.e., (0.5x0.5x(1.96/0.05)[2] = 384.16, which would round up to 385]. For the stripper well populations, the Agency considers a 10 percent margin of error (error = 0.10) to be acceptable. Therefore, the projected sample size needed for questions with proportional objectives for the stripper well populations is 97 [i.e., (0.5x0.5x(1.96/0.10)[2] = 96.04, which would round up to 97].
      For numeric value questions designed to estimate a mean value, the Agency's acceptable margin of error is dependent on the variability of the data. For certain emission sources, like equipment leaks or compressor emissions, emission values often vary over 4 to 5 orders of magnitude. With these highly variable emission sources, we have found that the relative standard deviation (standard deviation divided by the mean, s/u where u is the mean) is generally 3. For example, the average relative standard deviation for compressor emissions data from the Greenhouse Gas Reporting Program (GHGRP) is 2.76.  For sources with such large variability (i.e., σ/u ~ 3), we consider it reasonable to know the mean value within +-30% (i.e., error/u = 0.3 or error = 0.3u).  For data that are less variable (i.e., data that only vary over one or two orders of magnitude), the relative standard deviation is typically 1 or less (i.e., σ/u <= 1). For these less variable data, we consider it reasonable to know the mean value within +-10%. For both types of sources (i.e., those with more variable data and those with less variable data) we find that s/error = 10 provides a reasonable level of accuracy for the key populations (e.g., when s = 3u and error = 0.3u, then s/ error = 3u/(0.3u) = 10). Using s/error = 10 and the t value of 1.96 (based on a 95 percent 2-sided confidence level with population size greater than 30), the projected sample size needed for numeric value questions is 385 [i.e., (1.96x10)[2] = 384.16, which would round up to 385]. For the stripper well populations, the Agency considers a consider it reasonable to accept higher errors, such that the acceptable ratio of s/error = 5.   Therefore, the projected sample size needed for numeric value questions is 97 [i.e., (1.96x5)[2] = 96.04, which would round up to 97].
      Data precision can be characterized as the ability to distinguish the difference between two estimates obtained from a sample, which is termed the power of a conclusion in statistical terms. The sample size needed to assess differences between means is given by the following formula.
      n_o = [(Z1-α/2+Z1-β) / ES][2] 	when the objective is estimation of a mean
where, 
	Z1-α/2 =	z-statistic based on desired 2-sided confidence level; typically a value of Z1-α/2 = 1.96 for the 95 percent confidence interval is used in power analyses.
	Z1-β =	z-statistic based on desired 1-sided power level; Z1-β = 0.84 for 80 percent power and Z1-β = 1.282 for 90 percent power.
	ES =	the effect size =│u1 - u2│/σ.
      For proportional sampling, the sample size equation is the same, but the effect size, ES, is defined as ES =│p1 - p2│/ (px(1-p))[0.5]. 
      The effect size for differences in average values can be deduced from other available studies (e.g., available studies from which the standard deviation may deduced) or it can be selected based on recommended values. In the absence of more-specific prior information, it is common practice to use an effect size value of 0.5 when interested in discerning a moderate to large effect, and an effect size of 0.2 if interested in discerning a small effect.  Since no prior information on the standard deviation for most of the values requested in the information collection, we considered using the recommended value of 0.2 to discern a small effect on an average value for the key populations. For proportional questions, we consider it reasonable that a difference of 10 percent (p1 - p2 = 0.1) be discernable. The maximum value of the denominator, (px(1-p))[0.5], is 0.5 (when p = 0.5). Therefore, for proportional questions, we determined that an ES value of 0.2 (0.1/0.5=0.2) is appropriate. Thus, we concluded that, regardless of the type of question, effect size of 0.2 is sufficient for the purposes of this information collection effort. Using an effect size of 0.2 for a small effect, 80 percent power (Z1-β = 0.84), and a 95 percent confidence interval, the required sampling size is 196 (, i.e., [(1.96+0.84)/0.2][2]= 196). Using an effect size of 0.2 for a small effect, 90 percent power (Z1-β = 1.282), and a 95 percent confidence interval, the required sampling size is 263 (, i.e., [(1.96+1.282)/0.2][2]= 262.76). 
      Therefore, for any question included in the information collection request, we determined that the target sample size (for infinite population sizes) for the key populations is 385. We also determined that this sample size is sufficient for the needs of this information collection request in terms of our desired requirements of accuracy (error margin) and precision (effect size) for these populations.
      For the stripper well populations, we initially considered using the recommended value of 0.5 to discern a moderate effect on an average value. For proportional questions, we consider it reasonable that a difference of 20 percent (p1 - p2 = 0.2) be discernable. The maximum value of the denominator, (px(1-p))[0.5], is 0.5 (when p = 0.5). Therefore, for proportional questions, we determined that an ES value of 0.4 (0.2/0.5=0.4) is appropriate. Consequently, we determined that, regardless of the type of question, an effect size of 0.4 is sufficient for the purposes of this information collection effort to discern a moderate effect for the stripper well populations. Using an effect size of 0.4 for a moderate effect, 80 percent power (Z1-β = 0.84), and a 95 percent confidence interval, the required sampling size is 49 (, i.e., [(1.96+0.84)/0.4][2]= 49). Using an effect size of 0.4 for a moderate effect, 90 percent power (Z1-β = 1.282), and a 95 percent confidence interval, the required sampling size is 66 (, i.e., [(1.96+1.282)/0.2][2]= 65.69). 
      Therefore, for any question included in the information collection request, we determined that the target sample size (for infinite population sizes) for the stripper well populations is 97. We also determined that this sample size is sufficient for the needs of this information collection request in terms of our desired requirements of accuracy (error margin) and precision (effect size) for these populations.
      For populations of limited size (N), the actual sample size (n) needed to meet the ICR survey objectives is given by the following equation: 
      	n = n_o/(1+n_o/N)
      When applying this equation, we used the theoretical value of n_o of 384.16 for the key populations and 96.04 for the stripper well populations to calculate n and then rounded the calculated value of n up to the next highest integer. Table B-3 provides the results of this calculation based on the size for each of the facility type populations to be considered. 
      The Agency also estimates that facility response rates will be approximately 90 percent due to inaccurate contact information and facility closures. Therefore, the Agency also projected the number of detailed survey form requests that would have to be mailed out based this 90 percent response rate.  These results were rounded up to the next integer and are also provided in Table B-3. For populations with a large number of facilities, like the non-stripper light oil production segment population, 425 facilities (382/0.9) will be selected to receive the survey. For the LNG storage and the LNG import and export segments, there are a limited number of facilities, so a complete survey rather than sampling from the population will be employed.

[1]Number of requests sent calculated as Target Number of Responses/0.9. If this number exceeds the total number of facilities, the number of requests sent is equal to the facility count.

      To ensure that random sampling of facilities within the production segment includes a proportional number of facilities within a given basin, a proportional allocation of wells will be used within each production population. In proportional allocation, the number of wells selected from a given subcategory (e.g., the number of wells selected from a specific basin within a GOR population), nh is determined as follows:
                              nh = nrequests x (Nh/N)
where,
 	nh =	the number of wells of a specified type within a given production population to which requests will be sent.
nrequests =	the total number of wells for which requests will be sent within a given production population.
	Nh =	the total number of wells of a specified type within the population. 
	N =	the total number of wells within the population.
      In the proportional allocation, the values are rounded to the nearest integer, so that the sum of the all nh equals (but does not exceed) nrequests. Thus, if a given basin accounts for 20 percent of the all stripper wet gas wells, where nrequests = 107 (see Table B-3), then 21 stripper wet gas wells (107 x 0.20 = 21.4) will be randomly selected from that basin to receive the Part 2 survey.
4.	Respondent Sample Collection 
      A random selection process will be used as described above to determine the well ID numbers selected for the Part 2 survey. The facility that contains a well selected for the Part 2 survey must complete the Part 2 survey for every well at that facility. There may be cases where two selected wells will be located at a single facility. The Agency considers this unlikely given the large small fraction of production wells that will be selected compared to the total population of wells within each population. Additionally, the response rate factor used to estimate the number of wells selected is expected to help ensure that the targeted number of facility responses will be received even if some facilities contain multiple wells selected for the Part 2 survey. 
5.	Response Rates 
      Since the information will be requested pursuant to the authority of section 114 of the Act, EPA anticipates that all respondents that receive the questionnaire will submit information will do so. However, for most of the industry segments, we are unsure if the facility contact information we do have is accurate. While we are confident that we have good contact information for current GHGRP reporters, we are interested in obtaining information for a significant number of reporters that do not currently report to the GHGRP. Given the uncertainty in the accuracies of the contact information, we have estimated a 90 percent response rate for each industry segment.

Oil and Gas Information Collection Request
Part 1. Production Operator Survey
                                     Term
                                  Definition
Atmospheric storage tank
A class of storage tanks that store materials at approximately atmospheric pressure.  Atmospheric storage tanks may store liquids at ambient temperatures or at elevated temperatures (e.g., "heater treaters").
Barrel
A common unit of measurement for the volume of crude oil produced or processed. The volume of a barrel is equivalent to 42 US gallons.
Barrel of oil equivalent (BOE)
A unit of energy equal to 5.8-million British thermal units (5.8 MMBtu) based on the approximate energy released be burning one barrel of crude oil.  For the purposes of this information collection request, you may use 1 BOE = 1 barrel of crude oil produced and 1 BOE = 5,800 scf of natural gas produced rather than using a direct energy conversion.
Basin
Geologic provinces as defined by the American Association of Petroleum Geologists (AAPG) Geologic Note: AAPG-CSD Geologic Provinces Code Map: AAPG Bulletin, Prepared by Richard F. Meyer, Laure G. Wallace, and Fred J. Wagner, Jr., Volume 75, Number 10 (October 1991) (incorporated by reference, see §98.7) and the Alaska Geological Province Boundary Map, Compiled by the American Association of Petroleum Geologists Committee on Statistics of Drilling in Cooperation with the USGS, 1978.
Centralized production surface site
Any onshore surface site that obtains crude oil or natural gas directly from multiple well surface sites without a custody transfer, and includes all equipment used in the transportation, compression, stabilization, separation, storing or treating of crude oil and/or natural gas (including condensate) located at the surface site.
Centrifugal compressor
Any machine for raising the pressure of a gaseous stream by drawing in low pressure gas and discharging significantly higher pressure gas by means of mechanical rotating vanes or impellers. Screw, sliding vane, and liquid ring compressors are not centrifugal compressors for the purposes of this information collection request. 
Compressor
Any machine for raising the pressure of a gaseous stream by drawing in low pressure gas and discharging significantly higher pressure gas.
Condensate
Hydrocarbon liquid separated from natural gas that condenses due to changes in the temperature, pressure, or both, and remains liquid at standard conditions.
Crude oil 
A mixture of hydrocarbons that exists in liquid phase in natural underground reservoirs and remains liquid at atmospheric pressure after passing through surface separating facilities. Depending upon the characteristics of the crude stream, it may also include small amounts of non-hydrocarbons produced from oil, such as sulfur and various metals, drip gases, and liquid hydrocarbons produced from tar sands, gilsonite, and oil shale. 
Dry gas well
For the purposes of this ICR, a well that produces natural gas, other than coal bed methane, with a GOR greater than 1,000,000 scf/bbl.
Equipment
The set of articles or physical resources used in an operation or activity. 
Field operator site
A centralized office or company that serves as the overall manager of the operations of one or more wells sites.  
Flowback
The process of allowing fluids and entrained solids to flow from a well following a treatment, either in preparation for a subsequent phase of treatment or in preparation for cleanup and returning the well to production. The term flowback also means the fluids and entrained solids that emerge from a well during the flowback process. The flowback period begins when material introduced into the well during the treatment returns to the surface following hydraulic fracturing or refracturing. The flowback period ends when either the well is shut in and permanently disconnected from the flowback equipment or at the startup of production. The flowback period includes the initial flowback stage and the separation flowback stage.
Gas-to-oil-ratio (GOR)
The ratio of the volume of natural gas that is produced or that comes out of solution when crude oil is extracted from a well and equilibrated to standard conditions to the volume of hydrocarbon liquids (crude oil and condensate) produced after the natural gas comes out of solution. This is often calculated by dividing the measured natural gas production by the measured crude oil and condensate production.
Heavy oil well
For the purposes of this ICR, a well that produces crude oil with a GOR of 300 scf/bbl or less.
Hydraulic fracturing
The process of directing pressurized fluids containing any combination of water or other base fluid, proppant, and any added chemicals to penetrate a formation, generally to stimulate production, that subsequently require flowback to expel fracture fluids and solids during completions.
Hydraulic refracturing
Conducting a subsequent hydraulic fracturing operation at a well that has previously undergone a hydraulic fracturing operation. 
Light oil well
For the purposes of this ICR, a well that produces crude oil with a GOR greater than 300 scf/bbl but less than or equal to 100,000 scf/bbl.
NAICS code
The numerical code of up to 6 digits used by the North American Industry Classification System (NAICS) for classifying business establishments by industry sector.
Natural gas
A naturally occurring mixture or process derivative of hydrocarbon and non-hydrocarbon gases found in geologic formations beneath the earth's surface, of which its constituents include, but are not limited to methane, heavier hydrocarbons and carbon dioxide. Natural gas may be field quality, pipeline quality, or process gas.
Nonstripper well
A well that produces more than 15 barrels of oil equivalent (BOE) per day on average over a 12-month period.
Onshore
All facilities except those that are located in the territorial seas or on the outer continental shelf.
Onshore petroleum and natural gas production 
The oil and gas industry segment responsible for the extraction and production of crude oil, condensate, and/or natural gas and generally operate under NAICS code 211111 or 211112.
Owner or operator
Any person who owns, leases, operates, controls, or supervises an affected facility or a stationary source of which an affected facility is a part. 
Plugged well
A well that has been sealed, typically by filling a portion of the well bore with cement, in order to permanently abandon the well following State, local or other regulatory body requirements for plugging and abandoning the well. 
Producing well
A well for which crude oil or natural gas are actively flowing from a subsurface reservoir and through the wellhead valve. 
Reciprocating compressor 
A piece of equipment that increases the pressure of a gaseous stream by positive displacement, employing linear movement of the driveshaft.
Separator
A process vessel specifically designed to separate gaseous fluids from one or more liquid fluids produced from a well or as received via a pipeline. Generally, separators are operated at pressures greater than ambient air pressure.
Standard conditions
For the purposes of this ICR questionnaire, standard conditions may include any "standard" temperature between 288°K and 298°K and pressure between 1 bar (100 kilopascals) and 1 atmosphere. For emissions source tests, standard conditions refer to a temperature of 293°K (68°F) and a pressure of 1 atmosphere (101.3 kilopascals or 29.92 inches Hg).
Storage tank or vessel

Well completion
The process that allows for the flowback of petroleum or natural gas from newly drilled wells to expel drilling and reservoir fluids and tests the reservoir flow characteristics, which may vent produced hydrocarbons to the atmosphere via an open pit or tank.
Well depth
The vertical distance from the wellhead to the termination of the well bore in the reservoir.
Well head (or wellhead)
The piping, casing, tubing and connected valves protruding above the earth's surface for an oil and/or natural gas well. The wellhead ends where the flow line connects to a wellhead valve. The wellhead does not include other equipment at the well site except for any conveyance through which gas is vented to the atmosphere. 
Well shut-in pressure
The surface force per unit area exerted at the top of a wellbore when the wellhead valve is closed for at least 12 hours.
Well site facility

Well surface site 
One or more surface sites that are constructed for the drilling and subsequent operation of any oil well, natural gas well, or injection well. For purposes of this ICR, well surface site refers only to the well(s) and equipment at the disturbed area of land associated with the well(s). The well surface site area does not include equipment at a centralized production surface site not located at the well surface site.
Well testing
The determination of the production rate of a well or an assessment of reservoir characteristics for regulatory, commercial, or technical purposes. Well testing may or may not require venting of gas at the well surface site.
Wet gas well
For the purposes of this ICR, a well that produces natural gas, other than coal bed methane, with a GOR greater than 100,000 scf/bbl but less than or equal to 1,000,000 scf/bbl.

1. Labor rates and associated overhead costs were based on May 2015 raw labor rates for the Mining: Oil and Gas Extraction Sector (NAICS 211000), loaded using a factor of 110%. The resulting loaded of hourly rates are:  $176.95 for management personnel, $148.95 for engineering personnel, $65.10 for plant operator personnel, and $47.08 for clerical personnel. These values were taken from the Bureau of Labor Statistics Occupational Employment Statistics Survey Web site and reflect the latest values available (May 2015) and are available at: http://www.bls.gov/oes/current/naics3_211000.htm. 
2. Management hours are assumed to be 5 percent of technical (engineering + operator) hours, and clerical hours are assumed to be 10 percent of technical hours.
3. One time survey so most occurrences are 1. Assumed 2 tank feed samples would be taken for analysis from the separators for a typical facility; the cost of each analysis was estimated to be $1,200.
4. Number of respondents are dependent on the industry segment based on the targeted number of respondents and the type of equipment at each facility.  All facilities would have to complete the Facility, Equipment Leaks, and Blowdown Event forms and 3,818 total facility respondents are being targeted. Only production facilities will have production well sites, and there are 2,350 production facility respondents. Storage tanks were estimated to be at every production, gathering and boosting (G&B), processing, and transmission compression (TC) industry segments (2350+357+244+302 =3,253) and pneumatic devices were assumed to be used at 80% of  production facilities and 50 percent of G&B, processing, TC, and transmission pipeline facilities (0.8*2350+0.5*(357+244+302+273) =2,468). Acid gas removal units (AGRU) were assumed to be at 50 percent of production, G&B, and processing facilities ((2350+357+244)/2)=1,476). Dehydrators are expected to be at every processing plant, 50% of production and G&B facilities, and 20% of TC, underground storage, and LNG facilities (244+(2350+357)*0.5+(302+201+80+11)*0.2=1,716). Compressors were assumed to be at 50% of production facilities and processing plants and at all G&B, TC, underground storage, and LNG facilities (0.5*(2350+244)+357+302+201+80+11=2,248). Control devices were assumed to be at all production, G&B, and processing facilities and 50% of TC, underground storage and LNG facilities (2350+357+244+0.5*(302+201+80+11)=3,248). The number of respondents for pneumatic counts were assumed to be the same as the respondents completing the pneumatics device tab. For the equipment component counts, counts for gas processing and transmission pipelines were expected to take twice as long as other industry segments, so these segments were counted twice (3,818+244+273=4,335). For tank feed sampling and analysis, throughput limits were included in the requirements, so not everyone would require feed analysis; assumed every production and (G&B) facility, 50% of processing, and 25% of TC facilities would have to take feed samples for flash analysis (2350+357+0.5*244+0.25*302=2,905).
