Introduction and Background
Background
On December 26, 2007, President Bush signed the FY2008 Consolidated Appropriations Act authorizing funding for the EPA to issue a rule requiring the mandatory reporting of greenhouse gas (GHG) emissions (Consolidated Appropriations Act, 2008, Pub. L. No.110-161, 121 Stat 1844, 2128 (2008)). An accompanying joint explanatory statement directed the EPA to "use its existing authority under the Clean Air Act" to develop a mandatory GHG reporting rule.
The Final Greenhouse Gas Reporting Rule (Final GHG Reporting Rule) (40 CFR part 98) was signed on September 22, 2009 by Administrator Lisa Jackson and published in the Federal Register on October 30, 2009 (74 FR 56260). The Final GHG Reporting Rule, which became effective on December 29, 2009, included reporting of GHGs from the facilities and suppliers that the EPA determined appropriately responded to the direction in the 2008 Consolidated Appropriations Act. These source categories capture approximately 85 percent of U.S. GHG emissions through reporting by certain downstream facilities that emit GHG, as well as certain upstream suppliers of products that will result in GHG emissions when combusted, released or oxidized.
The GHG reporting requirements for subpart I were initially proposed on April 10, 2009 (74 FR 16448) along with reporting requirements for 39 other source categories and the general provisions for the EPA's GHG reporting program. The EPA did not, however, include subpart I in the Final GHG Reporting Rule (74 FR 56260). Instead, the EPA re-proposed the data reporting requirements for subpart I on April 12, 2010 (75 FR 18652). The data reporting requirements for subpart I were finalized on December 1, 2010 (75 FR 74774) as an amendment to Part 98.
Proposed Rule -- Grant for Reconsideration
Following the publication of the final subpart I rule in the Federal Register, the Semiconductor Industry Association (SIA) submitted an administrative petition on January 31, 2011 titled "Petition for Reconsideration and Request for Stay Pending Reconsideration of subpart I of the Final Rule for Mandatory Reporting of Greenhouse Gases" ("Petition for Reconsideration"), requesting reconsideration of numerous provisions in the final rule. Since that petition was filed, the EPA has published actions related to subpart I.
Final rule: Additional Sources of Fluorinated GHGs: Extension of Best Available Monitoring Provisions for Electronics Manufacturing (76 FR 36339, June 22, 2011). Granted the Petition for Reconsideration with respect to the provisions for the use of Best Available Monitoring Methods (BAMM). Extended three of the deadlines in subpart I related to using the (BAMM) provisions from June 30, 2011 to September 30, 2011.
Final rule: Changes to Provisions for Electronics Manufacturing to Provide Flexibility (76 FR 5942, September 27, 2011). Amended the calculation and monitoring provisions for the largest semiconductor manufacturing facilities to provide flexibility through the end of 2013 and extended two deadlines in the BAMM provisions.
Proposed rule: Proposed Confidentiality Determinations for subpart I and Proposed Amendments to Subpart I Best Available Monitoring Methods Provisions (77 FR 10434, February 22, 2012). Re-proposed confidentiality determinations for data elements in subpart I and proposed amendments to the provisions regarding the calculation and reporting of emissions from facilities that use BAMM.
Final rule: Revisions to Heat Transfer Fluid Provisions (77 FR 10373, February 22, 2012). Final rule amended the definition of fluorinated heat transfer fluids (fluorinated HTFs) and the provisions to estimate and report emissions from fluorinated HTFs.
Final rule: Confidentiality Determinations for Subpart I and Amendments to Subpart I Best Available Monitoring Methods Provisions (77 FR XXXXX, published XXXXX XX, 2012). Final confidentiality determinations for data elements in subpart I and final amendments to the provisions regarding the calculation and reporting of emissions from facilities that use BAMM.
In today's proposed rule, the EPA is granting reconsideration on the remaining issues in the Petition for Reconsideration. Section 3 of this document discusses the specific issues raised in the Petition for Reconsideration and the changes the EPA is proposing in response to the petition.
In summary, the major changes we are proposing will reduce industry reporting burden by providing all facilities with the choice of two calculation methods and removing the option for certain facilities to determine and use recipe-specific gas utilization rates and by-product formation rates. The proposed rule would provide the option for reporters to either (1) use default gas utilization rates or by-product formation rates, which have been revised for semiconductor manufacturing facilities to reflect new industry data provided to the EPA, or (2) conduct stack testing to establish site-specific emission factors (EFs) for fluorinated GHGs (F-GHGs) that would be used to calculate F-GHG emissions. The proposed amendments would ensure that the EPA receives high quality and current facility-specific data. The proposed amendments also include provisions for the periodic review of industry advancements and changes that may impact the default gas utilization rates and by-product formation rates and default destruction and removal efficiency (DRE) values used to estimate emissions, to ensure the continued collection of data that represent current industry practices. Additionally, the proposed stack testing approach allows for estimation of emissions based on periodic direct measurements of stack emissions from facilities. These proposed amendments would allow the EPA to accurately characterize and analyze GHG emissions from the electronics manufacturing industry.
Economic Analysis
This economic impact analysis considers the costs and benefits of today's proposed rulemaking and is intended to provide a measure of the costs of using resources to comply with the proposed GHG reporting requirements. This report documents the methods and results and proceeds as follows: Section 2 describes the current regulatory context into which the new rule will be integrated. Section 3 explains the development process for subpart I, and Section 4 details the individual cost analyses methodology used to evaluate the regulation. Section 5 presents the results of the economic impact analysis. Section 5 also qualitatively describes the benefits of the proposal. A review of executive orders is provided in Section 6, which is followed by a brief Economic Impact Analysis (EIA) summary and conclusion in Section 7.

Regulatory Background
The EPA is proposing amendments to the calculation and monitoring methodologies for subpart I, Electronics Manufacturing, of the Greenhouse Gas Reporting Program (GHGRP). Changes include revising certain calculation methods, amending data reporting requirements, and clarifying terms and definitions. The EPA is proposing these amendments to (1) improve calculation methods and data requirements to better reflect new industry data and current practice; (2) provide additional calculation methods to allow individual facilities to choose the method best suited for their operations; (3) provide flexibility in implementation to balance the burden associated with existing requirements; and (4) address sensitive business information concerns raised by SIA, while ensuring that reporters continue to provide the EPA with reliable facility specific GHG data. Many of the proposed changes are in response to the Petition for Reconsideration referenced in Section 1.
 The EPA's Overall Rulemaking Approach
The purpose of the GHGRP is to collect comprehensive and accurate data which will inform future climate change policies. To this end, the EPA identified the following goals of the GHGRP:
Obtain data that is of sufficient quality that it can be used to support a range of future climate change policies and regulations.
Balance the rule coverage to maximize the amount of emissions reported while excluding small emitters.
Create reporting requirements that are consistent with existing GHG reporting programs by using existing GHG emission estimation and reporting methodologies to reduce reporting burden, where feasible.
1..1 Timing of Proposed Rule Implementation
The EPA has requested comments on today's proposed amendments to subpart I and intends to address them and publish the final amendments in 2013. The proposed amendments would become effective on January 1, 2014 and facilities would be required to follow one of the new methods to estimate emissions beginning in 2014. The first reports of emissions estimated using the new methods would be submitted in 2015. However, for the reports for emissions in 2012 and 2013 that are submitted in 2013 and 2014, respectively, reporters would be expected to calculate emissions and other relevant data using the existing requirements under part 98.
Given the extent of the proposed changes, the EPA has determined that it is not feasible for sources to implement these changes for the data collected in 2013 and reported in 2014. Although the proposed revisions are expected to reduce compliance costs by changing and replacing existing calculation methods and regulatory requirements, time is nonetheless needed because these changes would greatly affect how emissions are calculated and the type of data that would be reported. For example, the EPA is proposing to give facilities the option of using a new stack testing method to measure and calculate facility F-GHG emissions, to revise process categories and associated emission factors, and to remove existing methods to calculate emissions using recipe-specific emission factors. Because of the potential change in data collection requirements compared to those established by the December 1, 2010 final subpart I rule, the EPA does not anticipate that facilities would have enough time to schedule stack tests, revise their current tracking and monitoring methods, or revise the data collection methods for the 2013 reporting year.
Furthermore, because the proposed rule may not be finalized until the second half of 2013, reporters using the current methods in subpart I would continue to use these methods for collecting data and calculating emissions until the end of 2013. Reporters would need to select new calculation methods based on the revisions that the EPA finalizes from today's action after the effective date of the final rule (expected January 1, 2014).
 Legal Authority
The EPA is proposing rule amendments to Part 98 under its existing CAA authority, specifically authorities provided in CAA section 114. As stated in the preamble to the 2009 final rule (74 FR 56260, October 30, 2009) and the Response to Comments on the Proposed Rule, Volume 9, Legal Issues, CAA section 114 provides the EPA broad authority to obtain the information in Part 98, including subpart I, because such data would inform and are relevant to the EPA's carrying out a wide variety of CAA provisions. As discussed in the preamble to the initial Part 98 proposal (74 FR 16448, April 10, 2009), CAA section 114(a)(1) authorizes the Administrator to require emissions sources, persons subject to the CAA, manufacturers of control or process equipment, or persons whom the Administrator believes may have necessary information to monitor and report emissions and provide such other information the Administrator requests for the purposes of carrying out any provision of the CAA.
In addition, the EPA is proposing confidentiality determinations for proposed data elements in subpart I, under its authorities provided in sections 114, 301 and 307 of the CAA. As mentioned above, CAA section 114 provides the EPA authority to obtain the information in Part 98, including those in subpart I. Section 114(c) requires that the EPA make publicly available information obtained under section 114 except for information (excluding emission data) that qualify for confidential treatment.
The Administrator has determined that this action (proposed amendments and confidentiality determinations) is subject to the provisions of section 307(d) of the CAA.
 Existing Reporting Programs
In addition to the federal GHGRP (40 CFR part 98), a number of voluntary and mandatory GHG programs already exist or are being developed at the state, regional, and federal levels. These programs have different scopes and purposes. Many focus on GHG emission reduction, whereas others are purely reporting programs. In addition to the GHG programs, other federal emission reporting programs and emission inventories are relevant to the GHG reporting rule. For example, since 1996, the EPA has operated a domestic voluntary partnership with the semiconductor industry aimed at reducing PFC emissions. As part of the partnership, a third party compiles data from participating semiconductor companies and submits an aggregate (not company-specific) annual PFC emissions report.
In developing the GHGRP, the EPA carefully reviewed the existing reporting programs, particularly with respect to emissions sources covered, thresholds, monitoring methods, frequency of reporting and verification. States may have, or intend to develop, reporting programs that are broader in scope or are more aggressive in implementation because those programs are either components of established reduction programs (e.g., cap and trade) or are being used to design and inform measures that reduced GHGs indirectly (e.g., energy efficiency). Where possible, the EPA built upon concepts in existing federal and state programs in developing the GHGRP. For a full summary of the reporting programs reviewed in the development of the mandatory reporting rule please see the Regulatory Impact Analysis for the Mandatory Reporting of Greenhouse Gas Emissions in the docket (EPA-HQ-OAR-2008-0508).

Development of Subpart I
This section provides additional details about the development of subpart I in response to the Petition for Reconsideration and SIA's May 26, 2011 letter supporting the development of the rule changes to provide flexibility that were finalized September 27, 2011. This section also provides a brief description of the affected entities and proposed changes in response to the Petition for Reconsideration and the proposed CBI determinations for emissions data.
 Affected Entities
Electronics manufacturing includes, but is not limited to, the manufacture of semiconductors, liquid crystal displays (LCDs), micro-electro-mechanical systems(MEMS), and photovoltaic cells (PV). The electronics industry uses multiple long-lived F-GHGs such as perfluorocarbons (PFCs), hydrofluorocarbons (HFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3), as well as nitrous oxide (N2O). This proposed rule would apply to electronics manufacturing facilities currently subject to subpart I, that is those that emit equal to or greater than 25,000 metric tons of CO2e per year from electronics manufacturing processes such as plasma etching, thin film deposition, chamber cleaning, and heat transfer fluid use. The proposed rule would (1) amend monitoring and calculation methodologies in Subpart I, (2) propose confidentiality determinations for the reporting of the new and revised data elements, and (3) amend subpart A, General Provisions, to reflect proposed changes to the reporting requirements in subpart I. For the purposes of this EIA, we will be examining only (1) above, because (2) and (3) will not significantly impact compliance costs.
Table 3-1 lists the types of entities that potentially could be affected by the reporting requirements under the subpart covered by this rule. However, this list is not intended to be exhaustive, but rather provides a guide for readers regarding facilities likely to be affected by this action. Other types of facilities not listed in the table could also be subject to reporting requirements. To determine whether an entity is affected by this action, one should carefully examine the applicability criteria found in 40 CFR part 98, Subpart A as well as 40 CFR part 98, subpart I.

 Summary of Major Changes -- Petition of Reconsideration
Following consideration of the issues raised in the Petition for Reconsideration and data presented by stakeholders, the EPA is proposing certain amendments to subpart I. These amendments would revise certain calculation methods, modify data reporting requirements, clarify terms and definitions, and provide technical corrections. Table 3-2 presents a summary of the outstanding issues raised by petitioners and the corresponding proposed change to the rule. Section III.B of the preamble to the proposed rule provides further detail including the EPA's rationale for each proposed change. Table 3-3 presents a summary of the existing and proposed reporting methods. In addition to the monitoring amendments proposed in rule, the EPA proposes CBI determinations for the new data elements that would be added or significantly revised by the proposed subpart I amendments (see Tables 3-2 and 3-3). The EPA currently plans to finalize these determinations after considering on public comment and concurrent with its finalization of the rule amendments to subpart I described above.

                           Proposed Changes to Rule
Rows 2 and 12 apply to semiconductor facilities only. All other rows apply to all electronics manufacturing facilities.
1. Addition of an emission estimation method as an alternative to recipe-specific emission factors. (See Section III.B.1)
Revising 40 CFR 98.93 to provide an option for using stack testing as an alternative method for determining fab-level emission factors for determining fab-level F-GHG emissions for all electronics manufacturing facilities.

Revising 40 CFR 98.94 to 98.98 to include the monitoring methods, QA/QC, missing data, reporting, recordkeeping, and definition requirements for the stack testing alternative.
2. Revision of default gas utilization rates and by-product formation rates for the plasma etch process type for semiconductor manufacturing. (See Section III.B.2)
Revise 40 CFR 98.92(a) and 40 CFR 98.93(a)(2) and (a)(4) to combine wafer cleaning and plasma etch emission processes and associated gas utilization rates and by-product formation rates. Revise Tables I - 3 and I - 4 for semiconductor manufacturing with new gas utilization rates and by-product formation rates based on gas type and process type or sub-type using additional data submitted by the Petitioner.
3. Removing recipe-specific emission factors: Requirements for (1) largest semiconductor manufacturing facilities (defined as those facilities with annual manufacturing capacity of greater than 10,500 m[2] of substrate) to use recipe-specific gas utilization rates and by-product formation rates to estimate emissions from plasma etch processes; and (2) semiconductor facilities using wafers greater than 300 mm diameter to estimate all of their emissions from processes that use fluorinated GHGs using recipe-specific gas utilization rates and by-product formation rates. (See Section III.B.3)
Revising 40 CFR 98.93, 98.94, 98.96, and 98.97 to remove provisions to use recipe-specific gas utilization rates and by-product formation rates and to combine the wafer cleaning process type with the plasma etch process type. Under this proposal, all semiconductor manufacturing facilities, regardless of manufacturing capacity, would have the option to use default gas utilization rates and by-product formation rates to estimate emissions from the plasma etching/wafer cleaning process type and from the following three subtypes of the chamber cleaning process type: in-situ plasma chamber cleaning, remote plasma chamber cleaning, and in-situ thermal chamber cleaning.
4. Calculation for determining manufacturing capacity. (See Section III.B.4)
Revising the terminology and definition of maximum designed substrate starts in 40 CFR 98.98 to be maximum substrate starts, meaning for the purposes of Equation I-5 in subpart I, the maximum quantity of substrates, expressed as surface area, that could be started each month in a reporting year based on the equipment installed in that facility and assuming that the equipment were fully utilized. Manufacturing equipment would be considered installed when it is on the manufacturing floor and connected to the required utilities.
5. Reporting provisions for facilities that have integrated production and research and development (R&D) activities. (See Section III.B.5)
Facilities would be allowed to report integrated production and R&D emissions and, if doing so, would be required to provide an estimate of the fraction of total emissions from their R&D activities under 40 CFR 98.96.
                                                                    (continued)

                           Proposed Changes to Rule
6. Requirements for the accuracy and precision of the equipment measuring gas consumption. (See Section III.B.6)
Removing the requirement for one percent of full-scale accuracy for "all flow meters, weigh scales, pressure gauges and thermometers..." in 40 CFR 98.93(i) and referencing the calibration accuracy requirements in 40 CFR 98.3(i) for all measurement devices used to measure quantities that are monitored in subpart I.
7. Provisions for re-calculating the facility-wide gas specific heel factor and handling exceptional circumstances. (See Section III.B.7)
Revising the criteria for an "exceptional circumstance" in 40 CFR 98.94(b)(4) from 20 percent of the original trigger point for change out to 50 percent for small cylinders (containing less than 9.08 kilograms (20 pounds) of gas). For large containers, the "exceptional circumstance" would remain as a change out point that differs by 20 percent of the trigger point used to calculate the gas specific heel factor. Clarifying the requirements for recalculating the facility-wide heel factor.
8. Requirements for verifying the model used to apportion gas consumption. (See Section III.B.8)
Revising 40 CFR 98.94(c) to allow for development of apportioning factors by using direct measurements using gas flow meters or weigh scales, to measure process sub-type, process type, stack system, or fab-specific input gas consumption.

Revising 40 CFR 98.94(c)(2)(i) to allow reporters to select a period of the reporting year and its duration that is representative of normal operations for the model verification. The representative period would be at least 30 days in duration, and may be as long as one year. The model would be verified using the F-GHG used in the greatest quantity, and would be corrected if it does not meet the verification requirements. A facility would be able to use two F-GHG for model verification if they both meet the criteria and if at least one of them is used in the greatest quantity.

Increasing the maximum allowed difference between the modeled and actual gas consumption in the verification process from 5 percent to 20 percent.
9. Provisions for calculating N2O emissions. (See Section III.B.9)
Revising 40 CFR 98.93(b), 40 CFR 98.96(c)(3) and 40 CFR 98.96(k) to clarify that facilities must calculate annual fab-level N2O emissions from the chemical vapor deposition (CVD) process type and from the aggregate of other electronics manufacturing production processes using default emission factors (facilities are not required to report emissions from each CVD process and from each other N2O using process).
10. Provisions for reporting controlled emissions from abatement systems. (See Section III.B.10)
Revising 40 CFR 98.94(f) to allow facilities to use either revised default destruction or removal efficiency (DRE) values or to establish a site-specific DRE value for each combination of input gas or by-product gas and process type or sub-type using directly measured DREs. Providing alternative methods for a facility to directly measure DRE.
                                                                    (continued)

                           Proposed Changes to Rule
11. Provisions for determining and calculating abatement system uptime. (See Section III.B.11)
Revising Equation I-15 to allow reporters to calculate the average uptime for the group of systems for each combination of input gas or by-product gas and process type or sub-type, using the same process categories in which F-GHG use and emissions are calculated. Abatement system uptime monitoring and calculation would be simplified by assuming that connected process tools operate with F-GHGs or N2O flowing continuously once they are installed; this would apply for all methods (both default emission factors and stack testing).
12. Absence of a method for updating gas utilization rates and by-product formation rates and DRE values for semiconductor manufacturing. (See Section III.B.12)
Revising the data reporting requirements in 40 CFR 98.96 to require certain semiconductor manufacturing facilities to provide a report to the EPA every 3 years covering technology changes at the facility that may affect gas utilization rates and by-product formation rates or DRE values.

Engineering Cost Analysis
Introduction
In November 2010 the EPA generated a subpart I engineering cost analysis detailing methods for compliance for subpart I. In September 2011, the EPA finalized changes that would temporarily allow the largest semiconductor facilities to estimate emissions from the plasma etching process type using the default emission factor method already included in the December 2010 rule. Given that the September 2011 amendments are temporary and will expire on December 31, 2013, requirements finalized in the December 2010 rulemaking serve as the baseline for this analysis. That is, the December 2010 final rule represents compliance requirements that would be effective in the absence of today's proposal. Accordingly, the costs estimated from December 2010 serve as the baseline comparison for this economic analysis.
In today's rulemaking, the EPA has proposed revisions to subpart I based on industry comments, the petition for reconsideration and associated efforts (see Section 3, Table 3-2 for a detailed summary of the proposed changes). Most notably, the EPA is proposing to remove the requirements for the largest semiconductor manufacturing facilities to develop and use recipe-specific factors to estimate emissions from etch processes. As indicated in the 2010 cost analysis, the average first year cost for a facility to comply with the recipe-specific method was $45,598 higher than complying with the default emission factor method (in 2006 dollars). Removal of this requirement therefore significantly decreases the estimated compliance costs.
In addition, today's rulemaking proposes two options: a method based on default emissions factors and process categories (the default emission factor method) for semiconductor manufacturing facilities, which has been modified from the previous subpart I rule, and a new, optional, stack testing method, which would apply to all facilities covered under subpart I. The EPA estimated costs for each affected industrial facility to comply with today's proposed rule by completing the default emission factor method.
The EPA also conducted a sensitivity analysis to estimate the costs for a scenario in which facilities chose to use the optional stack testing method instead of the default emission factor method. The EPA used available industry and EPA data to characterize conditions at affected sources. Incremental monitoring, recordkeeping, and reporting activities were then identified for each type of facility, and the associated costs were estimated.
Overall, the EPA's analysis shows that the proposed changes would reduce the national burden and that this reduction is driven largely by three items: the default emission factor option is updated to include 4 categories instead of 5 (see Table 3-2, item 2), the recipe-specific emission factor option is removed (Table 3-2, item 3), and the optional stack testing method is introduced (Table 3-2, item 1). All of these options are discussed in greater detail in this engineering cost analysis.
The engineering cost estimates presented do not include Items 4 through 11 in Table 3-2 because these items are primarily technical clarifications, corrections, and removal of requirements. Accordingly, these proposed changes would not result in significant cost impacts and on balance, would either maintain or reduce the overall burden to facilities.
 The engineering cost estimates presented also do not include item 12, which adds a requirement for certain semiconductor facilities to submit an additional report to the EPA every three years. This report would be optional for all facilities with F-GHG and N2O emissions below 40,000 metric tons of CO2e per year. It is estimated that only a few facilities (those with F-GHG and N2O emissions over 40,000 metric tons of CO2e per year) would need to file this report, and it would only require approximately 20 hours of additional industrial engineer/technician time. The EPA does not, however, have data available to develop a precise estimate of the number of facilities who would be required to submit the additional report every three years. Given that the EPA does not expect this requirement to significantly affect the compliance costs either on a per facility or a national basis, and the lack of robust data to estimate the number of affected facilities, these estimates are not included in the cost analysis.
Overview of Cost Analysis
The costs of complying with the changes proposed in today's rule would vary from one facility to another, depending on the types of emissions, the number of affected sources at the facility, existing monitoring, recordkeeping, and reporting activities at the facility, etc. In general, the compliance costs for affected facilities are the costs to monitor, record, and report F-GHG and N2O emissions. These costs include labor costs for performing the monitoring, recordkeeping, and reporting activities necessary to comply with the proposed rule as well as capital and operating and maintenance costs. All costs referred to in this section are reported in 2011 dollars, and the costs from the 2010 cost analysis (which were provided in 2006 dollars) have been converted up to 2011 dollars in order to facilitate a direct comparison of the costs from the 2010 and 2012 cost analyses.
For both the proposed option and the sensitivity analysis, we provide a general overview of baseline reporting (if data are available) as well as labor costs (i.e., the cost of labor by facility staff to meet the information collection requirements of the proposed rule). Capital costs and operating and maintenance costs (e.g., the cost of purchasing and installing monitoring equipment or contractor costs associated with providing the required information) are not discussed since we do not anticipate that capital or operating and maintenance costs will be incurred when complying with the default emission factor method or the optional stack method. Additional details of the data, methods, and assumptions underlying the costs are documented in following memos, which can be found in the docket (EPA-HQ-OAR-2011-0028): Technical Support for Accounting for Destruction or Removal Efficiency for Electronics Manufacturing Facilities under subpart I, Technical Support for Modifications to the Fluorinated Greenhouse Gas Emission Estimation Method Option for Semiconductor Facilities under subpart I, Technical Support for the Stack Test Option for Estimating Fluorinated Greenhouse Gas Emissions from Electronics Manufacturing Facilities under Subpart I, Technical Support for Other Technical Issues Addressed in Revisions to subpart I. The memos also include technical information on the assumptions and methods used to develop the proposed changes to subpart I covered by this analysis.
Baseline Reporting
To complete this analysis, the EPA is assuming that facilities are already in compliance with the existing subpart I requirements, as specified in the December 2010 rule. This EIA presents comprehensive costs for compliance with all of the subpart I requirements that would be in effect if today's proposal were finalized. The EIA also aggregates these costs to the national level and compares them to the national costs of the 2010 promulgated rule.
Reporting Costs
The EPA used the spreadsheets developed in conjunction with the initial economic evaluation for subpart I from 2010 to analyze today's proposed changes to subpart I. The template included three tables: analysis of reporting thresholds, analysis of monitoring and reporting options, and unit costs for monitoring and reporting. Key variables and data fields were clearly defined to ensure that costs developed for each subpart used a standard set of methods and assumptions.
Labor Costs. The costs of complying with and administering this rule include the time of managers, technical, and administrative staff in both the private sector and the public sector. Staff hours are estimated for activities including:
monitoring (private): staff hours to operate and maintain emissions monitoring systems;
reporting (private): staff hours to gather and process available data and report it to the EPA through electronic systems; and
assuring and releasing data (public): staff hours to quality assure, analyze, and release reports.
Staff activities and associated labor costs may vary over time. Thus, we develop and present cost estimates for reporting under the proposed revisions in the first year and the second year.
Loaded hourly labor rates (also referred to as "wage rates") were developed for several labor categories to represent the employer costs to use an hour of employees' time in each of the manufacturing sector labor categories used in this analysis. The labor categories correspond to the job responsibilities of the personnel that are likely to be involved in GHG emissions monitoring activities at the manufacturing facility level to comply with the rulemaking.
For purposes of this study, the EPA adopted the methodology used by Cody Rice (2002) to calculate the wage rates for the EPA's Toxics Release Inventory (TRI) Program. Thus, the wage rates calculated for different labor categories included the employer costs for employee compensation (comprising the basic wages and the corresponding benefits) and the overhead costs to the employer.
For each labor category, the following formula was used to calculate the wage rates:
	Loaded Hourly Labor Rate ($/hr.) = Basic Wages ($/hr.) *
	(1 + Benefits Loading Factor + Overhead Loading Factor).	(4.1)
The benefits loading factor corresponds to the relative share of benefits compensation in the total employee compensation (comprising basic wages and benefits). This factor, which reflects data from the Bureau of Labor Statistics' (BLS) Employer Costs for Employee Compensation (ECEC) indices, varies by labor category (0.37 to 0.50). The overhead loading factor (0.17) corresponds to the share of overhead costs to the employer relative to the total employee compensation. For purposes of this analysis, we have adopted the same overhead loading factor that Cody Rice (2002) used in her wage rate calculations. Thus, the overhead loading factor that we used in the wage rate calculations remains the same for all labor categories and across all industry types within the manufacturing sector.
The loaded labor rates for the four labor categories that are used in the cost analysis are reported in Table 4-1 below and are also reported in the appropriate sectors labor cost tables in the following sections.

Capital and O&M Costs. This includes the cost of purchasing and installing monitoring equipment or contractor costs associated with providing the required information. However, no capital costs are associated with complying with the proposed subpart I.
Other Recordkeeping and Reporting. Reporting costs totaling $3,152 per facility and recordkeeping costs totaling $1,824 were included in the default emission factor method for today's rule. These costs are in accord with the costs that were proposed in 2010, and were adjusted to reflect the distinction between fabs and facilities, which is discussed in more detail in Section 4.3.1. Although some minor modifications to recordkeeping and reporting have been included in the proposed rule, such as moving some abatement system requirements to recordkeeping and removing some abatement system requirements altogether, the EPA assumed that the cost impacts from these changes would be negligible when compared to the cost of the overall method used. For the new (optional) stack testing method, a reporting cost of $536 and a recordkeeping cost of $1,822 were included. These costs are discussed further in Sections 4.3.2 and 4.3.4.
Cost Analysis for Subpart I -- Electronics Manufacturers
The remainder of Section 4 provides the cost data associated with today's subpart I proposal, specifically the data and background information needed to understand the engineering costs analysis conducted for each source and the reporting option selection. The data are the basis for the economic impact analysis described in detail in Section 5 of this document.
Model Facility Development
This analysis is based on the costs of monitoring F-GHG and N2O emissions from electronics manufacturing facilities. The analysis for the original subpart I proposal (2010) corresponded to "fabs" as opposed to facilities. In that analysis, the breakdown of fab categories was provided as follows: non-semiconductor electronics (3 fabs), large semiconductor (29 fabs), and non-large semiconductor (62 fabs) for a total of 94 fabs. The non-semiconductor electronics category includes facilities that manufacture micro-electromechanical systems, liquid crystal displays, and photovoltaics.
In today's proposed rule, the EPA has proposed to amend subpart I to remove the distinction between large and non-large semiconductor facilities. Therefore, the breakdown of facility categories is as follows, on a facility basis: 3 non-semiconductor electronics facilities and 67 semiconductor facilities. This analysis assumes that each non-semiconductor facility, as listed in the 2010 rule, contains a single fab, and that each semiconductor facility, as listed in the 2010 rule, contains an average of 1.36 fabs, which changes the 2010 cost analysis total of 94 fabs to 70 facilities total, including both semiconductor and non-semiconductor facilities, for today's analysis. Note that the default emissions factor method is being modified for semiconductor manufacturing facilities only, and therefore today's updated analysis of that method focuses on semiconductor facilities. The calculations associated with the default emission factor method for MEMS, PV, and LCD facilities are unchanged in this rule. The new, optional stack testing method applies to all facilities covered under subpart I.
These methods being proposed today include the default emission factor method and the stack testing method. The EPA has included the most cost effective option -- the default emission factor method -- in its estimate of the total costs of the proposed rule, based on the assumption that facilities will choose the lowest cost monitoring option. However, some facilities have expressed a preference for an alternative, i.e., the stack method. When examining the first two years of costs (as is done in this analysis), the stack testing method appears more costly than default approach. However, the potential level of heterogeneity in the industry makes it difficult to estimate how many stack tests and retests a given facility may need per year. Additionally, the EPA is proposing provisions for facilities to use the same results from their periodic stack testing for up to five years if they meet certain criteria, which would temporarily remove the costs associated with conducting annual testing. Therefore, the EPA recognizes that it may be more cost-effective for some facilities to use the stack method instead. Therefore, the EPA has conducted a sensitivity analysis that assumes some facilities use the stack testing method. The EPA does not have tailored estimates that represent the costs to use the stack testing method at these particular facilities and used the compliance cost for a "model" facility. As a result, the EPA expects that the sensitivity analysis estimates may be notably higher than the costs that would be incurred by facilities that choose to implement this approach.
Determination of Cost Elements
The total costs associated with complying with the proposed rulemaking by completing the default emissions factor method for semiconductor manufacturing facilities were broken into monitoring costs and reporting costs, which are described below. The sensitivity analysis for the stack testing method is also presented below. The non-semiconductor costs remain the same from the 2010 cost analysis.
Monitoring Costs
Two types of monitoring costs were identified:
collection of activity data for estimating F-GHG and N2O emissions
annual costs to monitor controlled emissions from abatement systems
Collection of activity data for estimating F-GHG and N2O emissions. Semiconductor manufacturing facilities using the "default emission factor method" would be required to use an approach for estimating emissions which includes the following components: (1) gas consumption as calculated using the facility's purchase records, inventory, and gas-and facility- specific heel factors, (2) facility specific methods for apportioning gas usage (3) default emission factors (including factors for by-products) based on four process categories, and (4) either default DRE values or properly measured DRE values, where appropriate.
Some facilities may choose to use the "stack testing method" to comply with today's proposed revisions to subpart I. These facilities are required to estimate emissions using (1) gas consumption as calculated using the facility's purchase records, inventory, and gas-and facility-specific heel factors, (2) facility specific methods for apportioning gas usage for fluorinated GHGs, (3) updated default emissions factors for select stack systems that meet certain criteria to exempt them from testing, and (4) either EPA published default DRE value or properly measured DRE, where appropriate.
Annual costs to monitor controlled emissions from abatement systems. In the proposed rule, a number of abatement system requirements would be moved from reporting to recordkeeping. In addition, some abatement system requirements are being removed from subpart I altogether. Also, facilities that report abatement would now provide an effective DRE value. Facility costs incurred for assuring abatement systems are properly installed, operated, maintained, and reported, and accounting for uptime have been included in this cost analysis.
Subpart I currently requires facilities to use EPA published DRE default values or use properly measured DRE values if facilities choose to account for abatement system DRE, which is optional; today's proposal would give facilities the option to use additional methods to properly measure DRE. Since DRE testing is optional, the EPA's estimated costs for performing DRE testing was not included for any facility category in this cost analysis.
Reporting Costs
Two types of reporting costs were identified:
reporting F-GHG emission estimate
reporting heat transfer fluid emissions estimate
Reporting F-GHG emission estimate. Today's proposal would require electronics manufacturing facilities to complete and submit facility-specific annual reports. Costs associated with reporting activity data were included for all compliance options. The EPA has not accounted for any change in reporting costs with respect to abatement systems, but, as noted earlier, the EPA is proposing to move some abatement system reporting requirements to recordkeeping and removing some requirements altogether.
It is assumed there are no other costs associated with using default DRE values, other than those mentioned above. Facilities have the option to confirm abatement through direct DRE measurement. The reporting costs associated with DRE testing are not included because such reporting is optional.
Reporting heat transfer fluid emissions estimate. Electronics manufacturing facilities are required to complete and submit data-reporting forms about emissions from heat transfer fluids. Although not all facilities use heat transfer fluids, the EPA does not have an estimate of the number that do so. Therefore, the EPA assumed for purposes of the cost analysis that all facilities will need to report heat transfer fluid emissions.
Proportion of Facilities in the Different Model Facility Levels
For the electronics manufacturing industry, 70 facilities (which represent 94 out of 175 fabs) in the United States exceed the 25,000 mtCO2e threshold and account for 96 percent of total domestic semiconductor emissions. The number of each type of fab that the EPA estimates will meet the 25,000 mtCO2e threshold and required to report is identified in Table 4-2. These values have not changed substantially since the original subpart I rule was finalized and serve as the starting point for analyzing the cost impact of the proposed changes.

Assigning Costs to Cost Elements
The EPA used the four labor categories (legal, managerial, technical and clerical) and associated labor rates to assign costs to each of the cost elements (see Table 4-1). The EPA assigned responsibilities to each labor category to estimate labor hours.
Determining Labor Categories
To evaluate labor costs, it was not only necessary to determine the amount of time required for all of the tasks associated with monitoring, but also to determine who will perform each task.
Allocate Responsibilities and Estimate Labor Hours
The primary cost analysis assumes that all semiconductor manufacturing facilities report fluorinated greenhouse gas emissions using the default emission factor method. The sensitivity analysis assumes that some facilities will use an alternative and optional compliance method, the stack testing method.
Default Emission Factor Method
This section identifies the costs associated with complying with the rulemaking using the default emission factor method for semiconductor manufacturing facilities. Compliance costs for this option include only labor costs and do not require any non-labor (capital and O&M) costs. A semiconductor facility that utilizes the default emission factor method will complete testing for four process types or subtypes -- the plasma etching/wafer cleaning process type and chamber cleaning process type which includes three sub-types: in-situ plasma chamber cleaning, remote plasma chamber cleaning, and in-situ thermal chamber cleaning. The planning and quality assurance/quality control (QA/QC) costs are zero because the primary effort required by this proposed rule of calculating emissions is captured in the cost category of "sampling and analysis." Additionally, the requirements for reporting the emissions will also include the generation of the majority of the records that must be maintained, so no additional recordkeeping costs were included. The total first year cost for the default emission factor method is $18,130 per facility and includes only labor costs. Table 4-3 summarizes the labor costs associated with complying with the default emission factor method.

Out of the 67 semiconductor facilities that are above the GHGRP threshold, 21 of these facilities would have to comply with the recipe-specific emissions factor method (referred to as the "Tier 2d method" in the 2010 EIA) beginning in 2014 if the EPA does not promulgate the proposed removal of the recipe-specific method. The EPA estimated the labor cost of the recipe-specific method to be $23,153 per facility and the capital cost to be $40,575 per facility for the first year. The estimated cost for the default emission factor method under the 2010 rule totaled $21,418 per facility and included only labor costs. Under today's proposal, all semiconductor facilities, including those previously required to use the recipe-specific method, may comply with subpart I by using the default emission factor method, which reduces national costs in the first year by $1,108,830.  The cost-savings on a facility-specific basis depends on which method the facility would use in the absence of today's proposal.  The 21 facilities that EPA estimates would have used the recipe-specific method would each save $45,598 in the first year, which represents the difference between the 2010 cost of $63,728 for the recipe-specific method and the 2012 cost of $18,130 for the default emission factor method. The 46 facilities that would have used the default emission factor method would save $3,288 in the first year, which represents the difference between the 2010 cost of $21,418 and the 2012 cost of $18,130 for the default emission factor method.  The national cost savings increases to $4,709,815 in the second year because the capital cost for the recipe-specific method in the current subpart I increases significantly in the second year, while the proposed changes do not vary from year-to-year.
Labor hours for the default emission factor option in today's proposed rule were estimated using methods from the 2010 rulemaking cost analysis for semiconductor facilities and industry comments. Based on its experience with semiconductor facilities voluntarily reporting emission via its sector partnership and consideration of industry comments, the EPA continued to use the IPCC's Tier 2b method to estimate the labor hours borne by semiconductor facilities, and modified the hours to represent 4 process categories, as reflected in today's proposed rule. We have presented the labor costs as first year and second year costs for consistency with previous GHGRP estimates.
As shown in Table 4-3 above, first year sampling and analysis costs include 213.43 hours for the industrial engineer/technician, 4.89 administrative hours and 4.96 management hours. These costs apply to both the first and second year.
Table 4-3 also shows that first year reporting costs were estimated to include 28.82 industrial engineer/technician hours, 0.26 legal hours, 14.26 management hours and 10.14 administrative hours to compile and report data annually. First year recordkeeping costs were estimated to include 24.7 industrial engineer/technician hours, 2.39 management hours and 5.7 administrative hours. Both recordkeeping and reporting costs remain unchanged in the second year.
Optional Stack Testing Method
This section identifies the costs associated with complying with the rulemaking using the stack testing method, which is an option for all facilities covered under subpart I. Compliance costs for this option include only labor costs and do not require any non-labor (capital and O&M) costs. For purposes of the cost analysis, the EPA assumed that a facility that utilizes the stack method will have a total of six stack systems. Initially, all six of these systems will be analyzed using a modified version of 2006 IPCC Tier 2a method. Based on the results of the initial Tier 2a analysis, the EPA approximates that only one of the stack systems would be eligible to use the modified Tier 2a analysis, while the remaining five stack systems would need to complete stack testing. Additionally, the EPA assumed that 25 percent of the stacks requiring testing would need to be retested in order to comply with the rule. The total first year cost for the stack testing method is $101,808 in labor costs. Table 4-4 below summarizes the labor costs associated with complying with the optional stack testing method. Labor hours for the optional stack testing method are broken into two parts, the modified Tier 2a analysis and the stack systems test. The labor hours required for the modified Tier 2a analysis were estimated using corresponding default emission factor method option in the December 2010 rule for non-large semiconductor facilities.
For each of the six stack systems, first year Tier 2a costs include 48.91 hours for the industrial engineer/technician, 2.46 administrative hours and 2.50 management hours. This comes to a total of 293.46 hours for the industrial engineer/technician, 14.76 administrative hours and 15  management hours. These costs are included under "sampling" in Table 4-4 and apply to both the first and second year.

Stack testing labor hours were estimated for each of the five stack systems that would be required to complete testing, along with the 25% of stack systems that would need to be retested. For each stack systems, first year costs include 194.71 hours for the industrial engineer/technician, 12.76 administrative hours and 6.38 management hours. In total, this comes to 1,216.94 hours for the industrial engineer/technician, 79.75 administrative hours and 39.88 management hours at each facility. These costs apply to both the first and second year.
As shown in Table 4-4, recordkeeping costs were estimated on an annual basis, requiring 24.65 industrial engineer/technician hours, 2.39 management hours and 5.73 administrative hours to compile and store data, and costing $1,822. Labor requirements for preparing the annual report included 7.25 industrial engineer/technician hours, 0.7 management hours, and 1.69 administrative hours to prepare the annual report, at a cost of $536. These costs remain unchanged in the second year.
Initial planning and quality assurance/quality control costs were estimated for the time needed to review the rule, make arrangements for stack system testing and prepare required initial notifications and records. These planning hours include resolving questions, reviewing drawings, conducting source inspections, defining constraints, writing the engineering report and onetime costs for equipment leak measurement, such as walk-down and field verification, populating software and initial monitoring setup costs. Table 4-4 shows that the planning labor includes 1.8 hours for the industrial manager, 37.6 hours for the industrial engineer/technician, and 19 administrative hours, totaling $2,958. These costs remain unchanged in the second year.

Economic Impact Analysis
The EPA has prepared an EIA to provide decision makers with a measure of the social costs of using resources to comply with the proposed GHG reporting requirements. As noted in the EPA's (2010) Guidelines for Preparing Economic Analyses, several tools are available to estimate social costs and range from simple direct compliance cost methods to the development of a more complex market analysis that estimates market changes (e.g., price and consumption) and economic welfare changes (e.g., changes in consumer and producer surplus). Given data limitations and the size and scope of the proposed rule, the EPA has used the direct compliance cost method as a measure of social costs. In addition, the EIA briefly reviews the qualitative benefits of this proposed rule based on previous experience with emission inventory programs.
 Change in National Cost Estimates
As shown in Table 5-1, the total national costs for the primary analysis are estimated to be $1.7 million in the first year and $1.7 million in the second year (2011$). In comparison to the original EIA national cost estimates for subpart I, these cost estimates reflect a 38 percent and 73 percent reduction in burden for the first and second years of reporting.

 Economic Impact Analysis
The EPA assessed how the regulatory program may influence the profitability of companies by comparing the monitoring program costs to total sales (i.e., a "sales" test). The techniques and data we use are identical to the GHGRP and focus on small entities. We provide additional details of the analysis below.
1.1.1 Overall Method of Assessing Economic Impacts
To assess the possible economic impacts associated with the proposed rule, the EPA compared per-facility compliance costs to facility sales for facilities of various sizes. Data on sales revenues for facilities of various sizes was obtained from the Census Bureau's Statistics of U.S. Businesses (SUSB) database for 2007, the latest year for which data are available. SUSB provides establishment-level information on revenues by enterprise size every five years; the EPA is assuming that "enterprise" corresponds to firm or company, and "establishment" corresponds to facility. Facility-level costs of complying with the rule are compared to average sales revenues for the facilities owned by companies of various sizes in the tables below. As noted above, the focus of our analysis is impacts to small entities.
2.1.2 Assessing Economic Impacts on Small Entities
The first step in this assessment was to determine whether the proposed rule will have a significant impact on a substantial number of small entities (SISNOSE). To make this determination, the EPA used a screening analysis that allows us to indicate whether the EPA can certify the rule as not having a SISNOSE. The elements of this analysis included
identifying affected entities,
selecting and describing the measures and economic impact thresholds used in the analysis, and
determining SISNOSE certification category.
<IP_ADDRESS> Identify Affected Entities
The industry subpart covered by the proposed rule was identified during the development of the cost analysis for the reporting rule. The SUSB data provide national information on the distribution of economic variables by industry and size. These data were developed in cooperation with, and partially funded by, the Office of Advocacy of the Small Business Administration (SBA) (SBA, 2008a). The data include the number of establishments (Table 5-2), and receipts (Table 5-3) and present information on all entities in an industry covered by the rule; however, many of these entities would not be expected to report under the GHGRP because they would fall below the 25,000 MtCO2e threshold. SUSB also provides these data by enterprise employment size. The census definitions in this data set are as follows:

Since the SBA's business size definitions (http://www.sba.gov/size) apply to an establishment's ultimate parent company, we assume in this analysis that the enterprise definition above is consistent with the concept of ultimate parent company that is typically used for Small Business Regulatory Enforcement Fairness Act (SBREFA) screening analyses.
NA: Not available. SUSB did not report this data for disclosure or other reasons.
<IP_ADDRESS>
establishment: An establishment is a single physical location where business is conducted or where services or industrial operations are performed.
employment: Paid employment consists of full- and part-time employees, including salaried officers and executives of corporations, who were on the payroll in the pay period including March 12, 2007. Included are employees on sick leave, holidays, and vacations; not included are proprietors and partners of unincorporated businesses.
receipts: Receipts (net of taxes) are defined as the revenue for goods produced, distributed, or services provided, including revenue earned from premiums, commissions and fees, rents, interest, dividends, and royalties. Receipts exclude all revenue collected for local, state, and federal taxes.
enterprise: An enterprise is a business organization consisting of one or more domestic establishments that were specified under common ownership or control. The enterprise and the establishment are the same for single-establishment firms. Each multi-establishment company forms one enterprise -- the enterprise employment and annual payroll are summed from the associated establishments. Enterprise size designations are determined by the summed employment of all associated establishments.
Because the SBA's business size definitions (SBA, 2008b) apply to an establishment's "ultimate parent company," we assume in this analysis that the "enterprise" definition above is consistent with the concept of ultimate parent company that is typically used for Small Business Regulatory Enforcement Fairness Act (SBREFA) screening analyses and the terms are used interchangeably. We also report the SBA size standard(s) for each industry group in order to facilitate comparisons and different thresholds.
<IP_ADDRESS> Develop Small Entity Economic Impact Measures
The analysis generated a set of sales tests (represented as cost-to-receipt ratios) for NAICS codes associated with the subpart I. Although the appropriate SBA size definition should be applied at the parent company (enterprise) level, data limitations allowed us only to compute and compare ratios for a model establishment for six enterprise size ranges (i.e., all categories, enterprises with 1 to 20 employees, 20 to 99 employees, 100 to 499 employees, 500 to 999 employees, and 1,000 to 1,499 employees). This approach allows us to account for differences in establishment receipts between large and small enterprises and differences in small business definitions across affected industries. It is also a conservative approach, because an establishment's parent company (the "enterprise") may have other economic resources that could be used to cover the costs of the reporting program.
The primary analysis uses sales tests to examine the average establishment's total annualized mandatory reporting costs using the proposed default emission factor calculation method to the average establishment receipts for enterprises within several employment categories (Tables 5-4 and 5-5). The average entity costs used to compute the sales test are the same across all of these enterprise size categories. As a result, the sales-test will overstate the cost-to-receipt ratio for establishments owned by small businesses, because the reporting costs are likely lower than average entity estimates provided by the engineering cost analysis.
The sensitivity analysis uses sales tests to examine the average establishment's total annualized mandatory reporting costs using the proposed stack testing method to the average establishment receipts for enterprises within several employment categories (Tables 5-6 and 5-7). The average entity costs used to compute the sales test are the same across all of these enterprise size categories. As a result, the sales-test will overstate the cost-to-receipt ratio for establishments owned by small businesses, because the reporting costs are likely lower than average entity estimates provided by the engineering cost analysis.
<IP_ADDRESS> Results of Screening Analysis
The Regulatory Flexibility Act generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute, unless the agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small governmental jurisdictions, and small not-for-profit enterprises.
For the purposes of assessing the impacts of the rule on small entities, we defined a small entity as (1) a small business, as defined by SBA's regulations at 13 CFR Part 121.201; (2) a small governmental jurisdiction that is a government of a city, county, town, school district, or special district with a population of less than 50,000; or (3) a small organization that is any not- for-profit enterprise that is independently owned and operated and is not dominant in its field.

[a] The Census Bureau defines an enterprise as a business organization consisting of one or more domestic establishments that were specified under common ownership or control. The enterprise and the establishment are the same for single-establishment firms. Each multi-establishment company forms one enterprise -- the enterprise employment and annual payroll are summed from the associated establishments. Enterprise size designations are determined by the summed employment of all associated establishments.
Since the SBA's business size definitions (http://www.sba.gov/size) apply to an establishment's ultimate parent company, we assume in this analysis that the enterprise definition above is consistent with the concept of ultimate parent company that is typically used for Small Business Regulatory Enforcement Fairness Act (SBREFA) screening analyses
NA: Not available. SUSB did not report this data for disclosure or other reasons.

After considering the economic impact of the proposed rule on small entities, the EPA has concluded that this action will not have a significant economic impact on a substantial number of small entities. As shown in Tables 5-4 and 5-5, the average ratio of annualized reporting program costs to receipts of establishments owned by model small enterprises was generally less than 1 percent for industries presumed likely to have small businesses covered by the reporting program.
As shown in the sensitivity analysis (Tables 5-6 and 5-7), if enterprises voluntarily chose the higher cost stack testing option, several enterprise categories have ratios that exceed 3 percent of sales (e.g., enterprise with one to 20 employees). Given that this method is voluntary, we assume small entities would choose the lower cost method. However, the EPA recognizes that some facilities have expressed a preference for the alternative to use the stack systems testing method. In some cases the realized cost of the stack systems testing method may be less expensive than expressed in this analysis, due to the potential for a facility to become exempt from stack testing for up to 5 years if it meets certain criteria after the first several years of testing.
Below we take a more detailed look at the enterprise categories noted above as having sales test ratios above 1 percent.
<IP_ADDRESS> Threshold-based Analysis of Categories Having Sales Test Ratios Above 1 Percent
Microcomputer Manufacturing (334111), Semiconductor and Related Device Manufacturing (334413), and Other Electronic Component Manufacturing (334419)
Subpart I covers facilities included in NAICS codes for Microcomputer Manufacturing (334111), Semiconductor and Related Device Manufacturing (334413), and Other Electronic Component Manufacturing (334419). The census data covers a broader set of establishments than the facilities covered in the rule. In addition, preliminary EPA analyses of the relation between facility size (proxied by employment) and emissions show emission levels are proportional to facility size. As a result, small facilities with 1 to 20 employees are unlikely to emit more than 25,000 MtCO2e per year.
As a result of the limitations of the census data, we used secondary data sources to better identify the facilities that are likely to be subject to subpart I. The World Fab Watch and the Flat Panel Display Fabs on Disk datasets includes a total of 216 facilities potentially subject to subpart I; 70 of these facilities exceed the 25,000 ton threshold. The EPA was able to collect sales data for 39 of these facilities. Table 5-8 reports summary statistics for each analysis.

One facility had a sales test ratio above 1% under the primary analysis and 5 facilities had ratios above that threshold under the sensitivity analysis.
 Synopsis of Benefits
Under the GHGRP, the EPA requires the collection and verification of emission data from subpart I facilities. This section reviews the benefits of the GHGRP for subpart I facilities based on previous experience with emission inventory programs in the United States and abroad.
Recent policy discussions have highlighted potential benefits to society of the mandatory GHGRP (Pew, 2008). Benefits to the public include: building public confidence through clear and transparent emission measures and reports. A GHG reporting system will also have the benefit of providing policymakers and analysts with a data set that is comprehensive for the electronics industry if reporting is conducted under subpart I and other applicable subparts. Benefits to the industry include: identifying cost-effective GHG reduction opportunities and disclosing information, which provides firms with incentives to reduce emissions voluntarily and provides emission data to service industries, such as insurance and financial markets. Availability of emission information to the public, consumers, investors, corporations, and government regulators provides a sound basis for future policy analysis, which benefits society as a whole. Accurate and transparent information is necessary for the implementation of efficient approaches that meet environmental goals with the lowest cost to the economy.

Statutory and Executive Order Reviews
This section describes the EPA's compliance with several applicable executive orders and statutes.
 Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review
Under section 3(f)(4) of Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a "significant regulatory action" and is therefore not subject to review under Executive Orders 12866 and 13563 (76 FR 3821, January 21, 2011).
In addition, the EPA prepared this EIA, including an analysis of the potential costs associated with this action. The costs of the rule are reported in Section 4, and the economic impacts are reported in Section 5. The EPA's cost analysis demonstrates that the proposed changes would significantly reduce subpart I compliance costs. Specifically, the proposed changes would reduce nationwide compliance costs in the first year by 38 percent ($2.8 million to $1.7 million) and by 73 percent in the second year ($6.4 million to $1.7 million). Overall, the EPA has concluded that the costs of the F-GHG Reporting Rule under subpart I are outweighed by the potential benefits of more comprehensive information about GHG emissions.
 Paperwork Reduction Act
This proposed rule does not increase information collection burden. As previously mentioned, this proposed rule proposes amended reporting methodologies in subpart I, confidentiality determinations for reported data elements, and amendments to subpart A to reflect proposed changes to the reporting requirements in subpart I. The Office of Management and Budget (OMB) has previously approved the information collection requirements contained in subpart I, under 40 CFR part 98, under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq., and has assigned OMB control number 2060-0650 for subpart I. The OMB control numbers for the EPA's regulations in 40 CFR are listed at 40 CFR part 9. Additional information can be found in the docket (see file "Proposed Amendments and Confidentiality Determinations for Subpart I Information Collection Burden"). The EPA continues to be interested in the potential impacts of this action on the burden associated with the proposed amendments and welcome comments on issues related to such impacts.
 Regulatory Flexibility Act
The Regulatory Flexibility Act generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute unless the agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions.
The first step in this assessment was to determine whether the rule will have a significant impact on a substantial number of small entities (SISNOSE). To make this determination, the EPA used a screening analysis that allows us to indicate whether the EPA can certify the rule as not having a SISNOSE. The elements of this analysis included:
identifying affected sectors and entities,
selecting and describing the measures and economic impact thresholds used in the analysis, and
determining SISNOSE certification category.
1.2.1 Identify Affected Sectors and Entities
For purposes of assessing the impacts of this re-proposal on small entities, "small entity" is defined as: (1) a small business as defined by the Small Business Administration's regulations at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; or (3) a small organization that is any not-for-profit enterprise which is independently owned and operated and is not dominant in its field.
For the GHG Reporting Rule, small entity is defined as a small business as defined by the Small Business Administration's regulations at 13 CFR 121.201; according to these size standards, criteria for determining if ultimate parent companies owning affected facilities are categorized as small vary by NAICS. Small entity criteria range from total number of employees at the firm fewer than 100 to number of employees fewer than 1000. Tables 5-2 and 5-3 present small business criteria and enterprise size distribution data for affected NAICS.
2.2.2 Develop Small Entity Economic Impact Measures
The ratio of total annualized compliance costs to firm sales (or sales test) is the selected impact measure. Details are provided in Section 5.2, and results are presented in Tables 5-4 and 5-6 for first-year costs and in Tables 5-5 and 5-7 for second year costs. These sales tests examine the average establishment's total annualized mandatory reporting costs to the average establishment receipts for enterprises within several employment categories. The average entity costs used to compute the sales test are the same across all of these enterprise size categories. As a result, the sales-test will overstate the cost-to-receipt ratio for establishments owned by small businesses, because the reporting costs are likely lower than average entity estimates provided by the engineering cost analysis.
3.2.3 Results of Screening Analysis
After considering the economic impact of the rule on small entities, the EPA has concluded that this proposed rule will not have a significant economic impact on a substantial number of small entities. The average ratio of annualized reporting program costs to revenues for F-GHG firms owned by model small enterprises and likely to be affected by the proposed rule was generally less than 1 percent. For all three NAICS (334111, 334413, and 334419) covered by subpart I, however, some size categories (especially those with 1 - 20 employees) show costs exceeding 1 percent of sales (e.g., those with 1-20 employees had a cost-to-sales ratio of 2.10 percent, 1.79 percent, and 1.25 percent for NAICS 334111, 334419, and 334413, respectively). A more careful examination of impacts on small firms in these NAICS codes was conducted.
Analysis of firms in the three NAICS industries covered by subpart I shows that firms with fewer than 20 employees produce less than 1.4 percent of output; firms below the 25,000 Mt CO2e threshold release approximately 6 percent of emissions. Because emissions and production levels are highly correlated, firms with fewer than 20 employees are generally not expected to be affected by the final rule; if they are, their costs are likely to be lower than the overall average costs used in the screening analysis. Thus, the EPA does not expect the proposed rule to impose significant costs to a substantial number of small entities in NAICS 334111, 334413, and 334419.
After considering the economic impacts of today's proposed rule on small entities, the EPA certifies that this action will not have a significant economic impact on a substantial number of small entities. The small entities directly regulated by this final rule are facilities included in NAICS codes for Microcomputer Manufacturing (334111), Semiconductor and Related Device Manufacturing, (334413) and Other Electronic Component Manufacturing (334419). As shown in Tables 5-13 and 5-14 of the Economic Impact Analysis for the Mandatory Reporting of Greenhouse Gas Emissions Final Rule (74 FR 56260, October 30, 2009) available in docket number EPA-HQ-OAR-2008-0508, the average ratio of annualized reporting program costs to receipts of establishments owned by model small enterprises was less than 1 percent for industries presumed likely to have small businesses covered by the reporting program.
 Unfunded Mandates Reform Act
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 1531-1538, requires federal agencies, unless otherwise prohibited by law, to assess the effects of their regulatory actions on state, local, and tribal governments and the private sector. Federal agencies must also develop a plan to provide notice to small governments that might be significantly or uniquely affected by any regulatory requirements. The plan must enable officials of affected small governments to have meaningful and timely input in the development of the EPA regulatory proposals with significant federal intergovernmental mandates and must inform, educate, and advise small governments on compliance with the regulatory requirements.
This proposed rule proposes to (1) amend monitoring and calculation methodologies in subpart I; (2) assign subpart I data reporting elements into CBI data categories; and (3) amend subpart A to reflect proposed changes to the reporting requirements in subpart I. This proposed rule does not contain a federal mandate that may result in expenditures of $100 million or more for state, local, and tribal governments, in the aggregate, or the private sector in any one year. In some cases, the EPA has increased flexibility in the selection of methods used for calculating and reporting GHGs. Also in this proposed rule, the EPA is revising specific provisions to provide clarity on what is to be reported. These revisions do not add additional burden on reporters but offer flexibility. As part of the process of finalization of the subpart I rule, the EPA undertook specific steps to evaluate the effect of those final rules on small entities. Based on the proposed amendments to subpart I provisions, burden will stay the same or decrease, therefore the EPA's determination finding of no significant economic impact on a substantial number of small entities has not changed. Thus, this proposed rule is not subject to the requirements of sections 202 or 205 of the UMRA. This rule is also not subject to the requirements of section 203 of UMRA because it contains no regulatory requirements that might significantly or uniquely affect small governments. However, in developing Part 98, the EPA consulted with small governments pursuant to a plan established under section 203 of the UMRA to address impacts of regulatory requirements in the rule that might significantly or uniquely affect small governments. For a summary of the EPA's consultations with state and/or local officials or other representatives of state and/or local governments in developing Part 98, see Section VIII.D of the preamble to the final rule (74 FR 56370, October 30, 2009).
 Executive Order 13132: Federalism
This proposed rule does not have federalism implications. It will not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132. However, for a more detailed discussion about how Part 98 relates to existing state programs, please see Section II of the preamble to the final rule (74 FR 56266, October 30, 2009).This proposed rule, which is proposing amended calculation and reporting methodologies in subpart I, proposing new confidentiality determinations for data elements required under subpart I, and proposing amendments to subpart A to reflect proposed changes to the reporting requirements in subpart I, would only apply to certain electronics manufacturers. No state or local government facilities are known to be engaged in the activities that would be affected by the provisions in this proposed rule. This proposed rule also does not limit the power of states or localities to collect GHG data and/or regulate GHG emissions. Thus, Executive Order 13132 does not apply to this proposed rule.
In the spirit of Executive Order 13132, and consistent with the EPA policy to promote communications between the EPA and state and local governments, the EPA specifically solicits comment on this proposed rule from state and local officials. For a summary of the EPA's consultation with state and local organizations and representatives in developing Part 98, see Section VIII.E of the preamble to the final rule (74 FR 56371, October 30, 2009).
 Executive Order 13175: Consultation and Coordination with Indian Tribal Governments
This proposed rule does not have tribal implications, as specified in Executive Order 13175 (65 FR 67249, November 9, 2000). This proposed rule proposes to (1) amend monitoring and calculation methodologies in subpart I; (2) assign subpart I data reporting elements into CBI data categories; and (3) amend subpart A to reflect proposed changes to the reporting requirements in subpart I. This proposed rule does not have tribal implications, as specified in Executive Order 13175 (65 FR 67249, November 9, 2000). No tribal facilities are known to be engaged in the activities affected by this action. Thus, Executive Order 13175 does not apply to this proposed rule. For a summary of the EPA's consultations with tribal governments and representatives, see Section VIII.F of the preamble to the final rule (74 FR 56371, October 30, 2009). The EPA specifically solicits additional comment on this proposed action from tribal officials.
 Executive Order 13045: Protection of Children from Environmental Health and Safety Risks
The EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997) as applying only to those regulatory actions that concern health or safety risks, such that the analysis required under section 5-501 of the Executive Order has the potential to influence the regulation. This proposed rule, which is proposing to (1) amend monitoring and calculation methodologies in subpart I; (2) assign non-input subpart I data reporting elements into CBI data categories; and (3) determine the treatment of inputs to emission equations data elements, is not subject to Executive Order 13045 because it does not establish an environmental standard intended to mitigate health or safety risks.
 Executive Order 13211: Actions that Significantly Affect Energy Supply, Distribution, or Use
This proposed rule, which proposes to (1) amend monitoring and calculation methodologies in subpart I, (2) assign subpart I data reporting elements into CBI data categories, and (3) amend subpart A to reflect proposed changes to the reporting requirements in subpart I, is not subject to Executive Order 13211 (66 FR 28355, May 22, 2001), because it is not a significant regulatory action under Executive Order 12866.
 National Technology Transfer Advancement Act
Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law No. 104-113 (15 U.S.C. 272 note) directs the EPA to use voluntary consensus standards (VCS) in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by VCS bodies. The NTTAA directs the EPA to provide Congress, through OMB, explanations when the agency decides not to use available and applicable VCS.
This proposed rule, which is proposing to amend monitoring and calculation methodologies in subpart I, involves technical standards. The EPA is proposing to include a stack testing option that would involve using the following EPA reference methods:
Method 1 or 1A at 40 CFR part 60, appendix A-1, to select sampling port locations and the number of traverse points in the exhaust stacks.
Method 2, 2A, 2C, 2D, 2F, or 2G at 40 CFR part 60, appendix A-1 and A-2, to determine gas velocity and volumetric flow rate in the exhaust stacks.
Method 3, 3A, or 3B at 40 CFR part 60, appendix A-2, to determine the gas molecular weight of the exhaust using the same sampling site and at the same time as the F-GHG sampling is performed.
Method 4 at 40 CFR part 60, appendix A-3, to measure gas moisture content in the exhaust stacks.
Method 301 at 40 CFR part 63, appendix A, to perform field validations of alternative methods of measuring F-GHG emissions and abatement system DRE.
Method 320 at 40 CFR part 63, appendix A, to measure the concentration of F-GHG in the stack exhaust.
Consistent with the NTTAA, the EPA conducted searches to identify VCS in addition to these EPA methods. The EPA conducted searches for VCS from at least three different voluntary consensus standards bodies, including the following: ASTM, ASME, and International SEMATECH Manufacturing Initiative (ISMI). No applicable VCS were identified for EPA Methods 1A, 2A, 2D, 2F, or 2G. The method, ASME PTC 19.10 - 1981, Flue and Exhaust Gas Analyses, is not cited in this proposed rule for its manual method for measuring the oxygen, carbon dioxide and carbon monoxide content of the exhaust gas. ASME PTC 19.10 - 1981 is an acceptable alternative to EPA Methods 3A and 3B for the manual procedures only, and not the instrumental procedures. The VCS ASTM D6348 - 03 (2010), Determination of Gaseous Compounds by Extractive Direct Interface Fourier Transform (FTIR) Spectroscopy, has been reviewed by the EPA as a potential alternative to EPA Method 320. All data and information the EPA has received in support of the stack testing method used EPA Method 320. Since this industry contains specialized gases in low concentrations, the EPA would prefer to have supporting data prior to approving another test method. Because of this, the EPA is not proposing this standard as an acceptable alternative for EPA Method 320 in this proposed rule. We note that reporters have the option to obtain approval for this method under the procedures outlines in 98.94(k).
The EPA is proposing to revise the current subpart I provisions for determining abatement system DRE to incorporate language based on methods adapted from the ISMI 2009 Guideline for Environmental Characterization of Semiconductor Process Equipment -- Revision 2. The EPA is proposing to incorporate applicable portions of the ISMI 2009 Guideline into the rule in proposed Appendix A to subpart I. The EPA is not proposing to incorporate by reference the entire ISMI 2009 Guideline because the ISMI 2009 Guidelines have not been subject to the same level of peer review and validation as other alternative standards (e.g., ASTM or ASME standards). Therefore, The EPA is proposing to incorporate only those portions of the 2009 ISMI Guideline that the EPA has determined are needed to provide flexibility and reduce burden in subpart I.
The EPA identified no other VCS that were potentially applicable for subpart I in lieu of EPA reference methods. Therefore, the EPA does not intend to adopt other standards for this purpose. For the methods required or referenced by the proposed rules, a source may apply to the EPA for permission to use alternative test methods or alternative monitoring requirements in place of any required testing methods, performance specifications or procedures, as specified in proposed 40 CFR part 98, subpart I.
 Executive Order 12898: Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations
Executive Order 12898 (59 FR 7629, February 16, 1994) establishes federal executive policy on environmental justice. Its main provision directs federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental effects of their programs, policies, and activities on minority populations and low-income populations in the United States.
This proposed rule is proposing to (1) amend monitoring and calculation methodologies in subpart I; (2) assign subpart I data reporting elements into CBI data categories; and (3) amend subpart A to reflect proposed changes to the reporting requirements in subpart I. The EPA has determined that this proposed rule will not have disproportionately high and adverse human health or environmental effects on minority or low-income populations because it does not affect the level of protection provided to human health or the environment. This proposed rule addresses only reporting and recordkeeping procedures.

Section 6
Conclusions
This proposed rule would amend the reporting requirements of fluorinated greenhouse gas (F-GHG) and nitrous oxide (N2O) emissions from electronics manufacturing facilities. These F-GHG and N2O source categories are covered under subpart I of the GHGRP.
 Summary
Electronics manufacturing includes, but is not limited to, the manufacture of semiconductors, liquid crystal displays (LCDs), micro-electro-mechanical systems(MEMS), and photovoltaic cells (PV). The proposed rule affects entities in the electronics industry covered by NAICS codes 334111 (Microcomputer Manufacturing), 334413 (Semiconductor and Related Device Manufacturing), and 334419 (Other  Electronic Component Manufacturing). The electronics industry uses multiple long-lived F-GHGs such as perfluorocarbons (PFCs), hydrofluorocarbons (HFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3), as well as nitrous oxide (N2O). This proposed rule would apply to electronics manufacturing facilities currently subject to subpart I, that is those that that emit equal to or greater than 25,000 metric tons of CO2e per year from electronics manufacturing processes such as plasma etching, thin film deposition, chamber cleaning, and heat transfer fluid use. The proposed rule would (1) amend monitoring and calculation methodologies in subpart I, (2) propose confidentiality determinations for the reporting of the new and revised data elements, and (3) amend subpart A, General Provisions, to reflect proposed changes to the reporting requirements in subpart I.
 Estimated Costs and Impacts of the GHG Reporting Program
The EPA's cost analysis demonstrates that the proposed changes would significantly reduce Subpart I compliance costs. Specifically, the proposed changes would reduce nationwide compliance costs in the first year by 38 percent ($2.8 million to $1.7 million) and by 73 percent in the second year ($6.4 million to $1.7 million). The national costs are distributed to several economic sectors and represent less than 0.01% of 2008 gross domestic product. The EPA has concluded that the proposed rule will not have a significant macroeconomic impact on the national economy or on small entities within those sectors.
