April 2022

Part A of the Supporting Statement

1. Identification of the Information Collection

      1(a) Title of the Information Collection

NSPS for Steel Plants: Electric Arc Furnaces and Argon Oxygen Decarburization Vessels (40 CFR Part 60, Subparts AA, AAa, and AAb) (Proposed Amendments and New Standard), EPA ICR Number 1060.19, OMB Control Number 2060-0038. 

      1(b) Short Characterization/Abstract
      
      The New Source Performance Standards (NSPS) for Steel Plants: Electric Arc Furnaces and Argon Oxygen Decarburization Vessels (40 CFR Part 60, Subpart AA) were proposed on October 21, 1974, promulgated on September 23, 1975, and most recently-amended on February 22, 2005. These regulations apply to electric arc furnaces and dust-handling systems that commenced construction, modification, or reconstruction either after October 21, 1974 or on/or before August 17, 1983 at steel plants that produce carbon, alloy, or specialty steels. In addition, the New Source Performance Standards (NSPS) for these regulations (40 CFR Part 60, Subpart AAa) were proposed on August 17, 1983, promulgated on October 31, 1984, and most recently- amended on February 22, 2005. These latter regulations apply to electric arc furnaces, argon-oxygen decarburization vessels, and dust-handling systems that commenced construction, modification, or reconstruction after August 17, 1983 at steel plants that produce carbon, alloy, or specialty steels. The EPA is proposing amendments to AA and AAa and a new regulation AAb. New facilities include those that commenced construction, modification or reconstruction after the date of proposal of AAb. This information is being collected to assure compliance with 40 CFR Part 60, Subparts AA, AAa, and AAb.

      In general, all NSPS standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NSPS. 

--------------------------------------------------------------------------------
      Any owner/operator subject to the provisions of this part shall maintain a file containing these documents and retain the file for at least two years following the generation date of such maintenance reports and records. All reports are sent to the delegated state or local authority.     If there is no such delegated authority, the reports are sent directly to the U.S. Environmental Protection Agency (EPA) regional office.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The "Affected Public" are steel plants that produce carbon, alloy, or specialty steels. The "burden" to the Affected Public may be found below at the end of this document in Table 1: Annual Respondent Burden and Cost  -  NSPS for Steel Plants: Electric Arc Furnaces and Argon Oxygen Decarburization Vessels (40 CFR Part 60, Subparts AA, AAa, and AAb) (Proposed Amendments and New Standard). The "burden" to the Federal Government is attributed entirely to work performed by either Federal employees or government contractors and can be found below at the end of this document in Table 2: Average Annual EPA Burden and Cost  -  NSPS for Steel Plants: Electric Arc Furnaces and Argon Oxygen Decarburization Vessels (40 CFR Part 60, Subparts AA, AAa, and AAb) (Proposed Amendments and New Standard). There are approximately 88 steel plants, which are owned and operated by the steel industry. None of the 88 steel plants in the United States are owned by either state, local, tribal or the Federal government. They are all owned and operated by privately-owned, for-profit businesses. . 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      Over the next three years, an average of approximately 89 respondents per year will be subject to these standards, and three additional respondents will become subject to these same standards over the three-year period of this ICR (1 respondents per year). This results in an annual average of 90 respondents per year.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The Office of Management and Budget (OMB) approved the currently-active ICR without any "Terms of Clearance. 

--------------------------------------------------------------------------------
2. Need for and Use of the Collection
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      2(a) Need/Authority for the Collection
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The EPA is charged under Section 111 of the Clean Air Act (CAA), as amended, to establish standards of performance for new stationary sources that reflect: 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            . . . application of the best technological system of continuous emissions reduction which (taking into consideration the cost of achieving such emissions reduction, or any non-air quality health and environmental impact and energy requirements) the Administrator determines has been adequately demonstrated. Section 111(a)(l).
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The Agency refers to this charge as selecting the best demonstrated technology (BDT). Section 111 also requires that the Administrator review and, if appropriate, revise such standards every eight years. In addition, section 114(a) states that the Administrator may require any owner/operator subject to any requirement of this Act to: 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (A) Establish and maintain such records; (B) make such reports; (C) install, use, and maintain such monitoring equipment, and use such audit procedures, or methods; (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; (F) submit compliance certifications in accordance with Section 114(a)(3); and (G) provide such other information as the Administrator may reasonably require.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      In the Administrator's judgment, particulate matter (PM) emissions from electric arc furnaces, argon-oxygen decarburization vessels, and dust handling systems either cause or contribute to air pollution that may reasonably be anticipated to endanger public health and/or welfare. Therefore, the NSPS were promulgated for this source category at 40 CFR Part 60, Subparts AA and AAa and a new regulation for AAb. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      2(b) Practical Utility/Users of the Data
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The recordkeeping and reporting requirements in these standards ensure compliance with the applicable regulations which were promulgated in accordance with the Clean Air Act. The collected information is also used for targeting inspections and as evidence in legal proceedings.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Performance tests are required in order to determine an affected facility's initial capability to comply with the emission standards. Continuous emission monitors are used to ensure compliance with the standards at all times. During the performance test a record of the operating parameters under which compliance was achieved may be recorded and used to determine compliance in place of a continuous emission monitor.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The notifications required in the standards are used to inform the Agency or delegated authority when a source becomes subject to the requirements of these regulations. The reviewing authority may then inspect the source to check if the pollution control devices are properly installed and operated, leaks are being detected and repaired, and the standards are being met. The performance test may also be observed.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The required semiannual reports are used to determine periods of excess emissions, identify problems at the facility, verify operation/maintenance procedures and for compliance determinations.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
3. Non-duplication, Consultations, and Other Collection Criteria
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The requested recordkeeping and reporting are required under 40 CFR Part 60, Subparts AA, AAa, and AAb.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      3(a) Non-duplication
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
       If the subject standards have not been delegated, the information is sent directly to the appropriate EPA regional office. Otherwise, the information is sent directly to the delegated state or local agency. If a state or local agency has adopted its own similar standards to implement the Federal standards, a copy of the report submitted to the state or local agency can be sent to the Administrator in lieu of the report required by the Federal standards. Therefore, duplication does not exist.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      3(b) Public Notice Required Prior to ICR Submission to OMB
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      This section is not applicable because this is a rule-related ICR. Nevertheless, the ICR will be available for public review during the public comment period following publication of the proposed Subpart AA, AAa, and AAb amendments in the Federal Register.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      3(c) Consultations
--------------------------------------------------------------------------------
      
      The Agency has consulted industry experts and internal data sources to project the number of affected facilities and industry growth over the next three years. The primary source of information as reported by industry, in compliance with the recordkeeping and reporting provisions in these standards, is the Integrated Compliance Information System (ICIS). ICIS is EPA's database for the collection, maintenance, and retrieval of compliance data for industrial and government-owned facilities. The growth rate for the industry is based on our consultations with the Agency's internal industry experts. Approximately 89 respondents will be subject to these same standards over the three-year period covered by this ICR.

      Stakeholder outreach occurred with industry groups including Steel Manufacturers Association (SMA) and American Iron and Steel Institute (AISI). Further stakeholder and public input is expected through public comment following publication of the proposed amendments and new standard to Subpart AA, AAa, and AAb in the Federal Register and follow-up meetings with interested stakeholders.
      
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      3(d) Effects of Less-Frequent Collection
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Less-frequent information collection would decrease the margin of assurance that facilities are continuing to meet these standards. Requirements for information gathering and recordkeeping are useful techniques to ensure that good operation and maintenance practices are applied and emission limitations are met. If the information required by these standards was collected less frequently, the proper operation and maintenance of control equipment and the possibility of detecting violations would be less likely.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      3(e) General Guidelines
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These reporting or recordkeeping requirements do not violate any of the regulations promulgated by OMB under 5 CFR Part 1320, Section 1320.5.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      3(f) Confidentiality
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Any information submitted to the Agency for which a claim of confidentiality is made will be safeguarded according to the Agency policies set forth in Title 40, chapter 1, part 2, subpart B - Confidentiality of Business Information (CBI) (see 40 CFR 2; 41 FR 36902, September 1, 1976; amended by 43 FR 40000, September 8, 1978; 43 FR 42251, September 20, 1978; 44 FR 17674, March 23, 1979).
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      3(g) Sensitive Questions
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The reporting or recordkeeping requirements in these standards do not include sensitive questions.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
5. The Information Collected: Agency Activities, Collection Methodology, and Information Management
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      5(a) Agency Activities 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      EPA conducts the following activities in connection with the acquisition, analysis, storage, and distribution of the required information:
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
Agency Activities

--------------------------------------------------------------------------------
Review notifications and reports, including performance test reports, and excess emissions reports, required to be submitted by industry.

--------------------------------------------------------------------------------
Audit facility records.
--------------------------------------------------------------------------------
Input, analyze, and maintain data in the Enforcement and Compliance History Online (ECHO) and ICIS. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      5(b) Collection Methodology and Management
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Following notification of startup, the reviewing authority could inspect the source to determine whether the pollution control devices are properly installed and operated. Performance test reports are used by the Agency to discern a source's initial capability to comply with the emission standards. Data and records maintained by the respondents are tabulated and published for use in compliance and enforcement programs. The semiannual reports are used for problem identification, as a check on source operation and maintenance, and for compliance determinations.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Information contained in the reports is reported by state and local governments in the ICIS Air database, which is operated and maintained by EPA's Office of Compliance. ICIS is EPA's database for the collection, maintenance, and retrieval of compliance data for industrial and government-owned facilities. EPA uses ICIS for tracking air pollution compliance and enforcement by local and state regulatory agencies, EPA regional offices and EPA headquarters. EPA and its delegated Authorities can edit, store, retrieve and analyze the data.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
       The records required by these regulations must be retained by the owner/operator for two years.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      5(c) Small Entity Flexibility
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The majority of  respondents are small entities (i.e., small businesses). The recordkeeping and reporting requirements are the same for both small and large entities       (mini-mills), since the process operations and the types of control equipment employed by     them are similar, independent of their size. However, EPA reduced the reporting frequency for this information from quarterly to semiannually in a December 1990 Federal Register notice to reduce the impact of reporting burden on small businesses. The Agency considers these to be the minimum requirements needed to ensure compliance and, therefore, cannot reduce them further for small entities. To the extent that larger businesses can use economies of scale to reduce their burden, the overall burden will be reduced. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      In EPA's 1979 Review of Standards of Performance for Electric Arc Furnaces in the Steel Industry, it was noted that approximately 84 percent of the facilities subject to these standards were small entities. In 2022, approximately 6 percent of the facilities subject to these standards are small businesses.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      5(d) Collection Schedule
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The specific frequency for each information collection activity within this request is shown below at the end of this document in Table 1: Annual Respondent Burden and Cost  -  NSPS for Steel Plants: Electric Arc Furnaces and Argon Oxygen Decarburization Vessels (40 CFR Part 60, Subparts AA, AAa, and AAb) (Proposed Amendments and New Standard).
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
6. Estimating the Burden and Cost of the Collection
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Table 1 documents the computation of individual burdens for the recordkeeping and reporting requirements applicable to the industry for each of the subparts included in this ICR. The individual burdens are expressed under standardized headings believed to be consistent with the concept of `Burden' under the Paperwork Reduction Act. Where appropriate, specific tasks and major assumptions have been identified. Responses to this information collection are mandatory.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The Agency may neither conduct nor sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB Control Number.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      6(a) Estimating Respondent Burden
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The average annual burden to industry over the next three years from these recordkeeping and reporting requirements is estimated to be 57,100 hours (Total Labor Hours from Table 1 below). These hours are based on Agency studies and background documents from the development of the regulation, Agency knowledge and experience with the NSPS program,     the previously-approved ICR, and any comments received.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      6(b) Estimating Respondent Costs
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (i) Estimating Labor Costs 
--------------------------------------------------------------------------------
 
--------------------------------------------------------------------------------
      This ICR uses the following labor rates: 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Managerial   $153.55 ($73.12 + 110%)  
--------------------------------------------------------------------------------
      Technical    $122.20 ($58.19 + 110%)
--------------------------------------------------------------------------------
            Clerical         $61.51 ($29.29 + 110%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 2021, "Table 2. Civilian Workers, by occupational and industry group." The rates are from column 1, "Total compensation." The rates have been increased by 110 percent to account for the benefit packages available to those employed by private industry.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (ii) Estimating Capital/Startup and Operation and Maintenance Costs
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The type of industry costs associated with the information collection activities in the subject standards are both labor costs which are addressed elsewhere in this ICR and the costs associated with continuous monitoring. The capital/startup costs are one-time costs when a facility becomes subject to these regulations. The annual operation and maintenance costs are the ongoing costs to maintain the monitors and other costs such as photocopying and postage.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (iii) Capital/Startup vs. Operation and Maintenance (O&M) Costs

1 Assumes that 40 percent of all respondents are using negative baghouses (36). Of these respondents, 66.6 percent (23.98 respondents) use COMS to measure stack emissions and 33.4 percent (12.02 respondents) have elected to use the alternative option of BLDS monitoring coupled with visible emissions observations instead of using COMS.  
--------------------------------------------------------------------------------
2 Assumes 51.7 percent (46.53) of all respondents have elected to comply with the fugitive emissions monitoring requirements by measuring the furnace static pressure continuously. The operating and maintenance costs associated with the pressure monitors are negligible.
--------------------------------------------------------------------------------
3 All respondents (90) are required to install flow rate monitors as part of the monitoring of operations rule requirements. The operating and maintenance costs associated with the flow monitors are negligible.
--------------------------------------------------------------------------------
Note: Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total capital/startup costs for this ICR are $18,300. This is the total of column D in the above table. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total operation and maintenance (O&M) costs for this ICR are $179,820. This is the total of column G. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The average annual cost for capital/startup and operation and maintenance costs to this industry over the next three years of the ICR is estimated to be $198,000. These are the  record-keeping costs. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      6(c) Estimating Agency Burden and Cost
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The only costs to the Agency are those costs associated with analysis of the reported information. EPA's overall compliance and enforcement program such includes activities as the examination of records maintained by the respondents, periodic inspection of sources of emissions, and the publication and distribution of collected information. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The average annual Agency cost during the three years of the ICR is estimated to be $86,200. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      This cost is based on the average hourly labor rate as follows:

            Managerial$69.04 (GS-13, Step 5, $43.15 + 60%) 
Technical$51.23 (GS-12, Step 1, $32.02 + 60%)
Clerical$30.32 (GS-6, Step 3, $18.95 + 60%)

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These rates are from the Office of Personnel Management (OPM), 2021 General Schedule, which excludes locality rates of pay. The rates have been increased by 60 percent to account for the benefit packages available to Federal government employees. Details upon which this estimate is based appear at the end of this document in Table 2: Average Annual EPA Burden and Cost  -  NSPS for Steel Plants: Electric Arc Furnaces and Argon Oxygen Decarburization Vessels (40 CFR Part 60, Subparts AA, AAa, and AAb) (Proposed Amendments and New Standard).

--------------------------------------------------------------------------------
      6(d) Estimating the Respondent Universe and Total Burden and Costs
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Based on our research for this ICR, there are 88 sources currently subject to these standards, and we expect three additional sources to become subject over the three-year period of this ICR. On average over the next three years, approximately 89 existing respondents will be subject to these standards. It is estimated that an additional 1 respondents per year will become subject to these same standards. The overall average number of respondents, as shown in the table below, is 90 per year. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The number of respondents is calculated using the following table that addresses the three years covered by this ICR:

      6(e) Bottom Line Burden Hours and Cost Tables
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The detailed bottom line burden hours and cost calculations for both the respondents and the Agency are shown below in Tables 1 and 2 at the end of this document, respectively, and summarized below. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (i) Respondent Tally
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total annual labor hours are 57,100 hours (rounded). Details regarding these estimates may be found below in Table 1: Annual Respondent Burden and Cost  -  NSPS for Steel Plants: Electric Arc Furnaces and Argon Oxygen Decarburization Vessels (40 CFR Part 60, Subparts AA, AAa, and AAb) (Proposed Amendments and New Standard). 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      We assume that burdens for managerial tasks take 5% of the time required for technical tasks because the typical tasks for managers are to review and approve reports. Clerical burdens are assumed to take 10% of the time required for technical tasks because the typical duties of clerical staff are to proofread the reports, make copies and maintain records.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      Furthermore, the annual public reporting and recordkeeping burden for this collection of information is estimated to average 310 hours per response.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The total annual capital/startup and O&M costs to the regulated entity are $198,000 (rounded). The cost calculations are detailed in Section 6(b)(iii), Capital/Startup vs. Operation and Maintenance (O&M) Costs.
--------------------------------------------------------------------------------
                  
--------------------------------------------------------------------------------
            (ii) The Agency Tally
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The average annual Agency burden and cost over next three years is estimated to be 1,720 labor hours at a cost of $86,200; see below in Table 2: Average Annual EPA Burden and Cost  -  NSPS for Steel Plants: Electric Arc Furnaces and Argon Oxygen Decarburization Vessels (40 CFR Part 60, Subparts AA, AAa, and AAb) (Proposed Amendments and New Standard).
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      We assume that burdens for managerial tasks take 5% of the time required for technical tasks because the typical tasks for managers are to review and approve reports. Clerical burdens are assumed to take 10% of the time required for technical tasks because the typical duties of clerical staff are to proofread the reports, make copies and maintain records.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      6(f) Reasons for Change in Burden
      
--------------------------------------------------------------------------------
      There is an adjustment increase in the total estimated burden as currently identified in the OMB Inventory of Approved Burdens. This increase is not due to any program changes.  The adjustment increase in `burden' from the most recently-approved ICR is due to an increase in the number of new or modified sources, which is based on an assumption of continued growth in the industry. There is also an adjustment increase in capital and operation and maintenance costs due to the increase in the number of respondents.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      6(g) Burden Statement
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The annual public reporting and recordkeeping burden for this collection of information is estimated to average 310 hours per response. `Burden' means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information either 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 neither conduct nor sponsor, and a person is not required to respond to,    a collection of information unless it displays a valid OMB Control Number. The OMB Control Numbers for EPA regulations are listed at 40 CFR Part 9 and 48 CFR Chapter 15.

Assumptions:

a  We have assumed that there are an annual average of 89 sources currently subject to the NSPS, subparts AA and AAa. We have further assumed there will be three new minimills over the three-year period of this ICR (1 new respondent per year) subject to subpart AAb. Therefore, the average number of respondents per year is estimated to be 90.
b  This ICR uses the following labor rates: $153.35 per hour for Executive, Administrative, and Managerial labor; $122.20 per hour for Technical labor, and $61.51 per hour for Clerical labor.  These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 2021, "Table 2. Civilian Workers, by Occupational and Industry group."  The rates are from column 1, "Total Compensation."  The rates have been increased by 110% to account for the benefit packages available to those employed by private industry.
c  We have assumed that existing sources are in compliance with initial rule requirements including the initial performance test and notification requirements.  We have further assumed there will be three new minimills over the three-year period of this ICR subject to subpart AAb. We have assumed that 5 percent of the sources would repeat performance tests due to failure. We have assumed 1.64 baghouses per new facility based on collected information from existing sources (1.64 = 54 baghouses / 33 EAF facilities).
d Method 5 test every 5 years on each new EAF control device after initial test at startup, 3 facilities. We have assumed 1.64 baghouses per new facility based on collected information from existing sources (1.64 = 54 baghouses / 33 EAF facilities).
e  Daily monitoring of operations includes time and duration of each charge, time and duration of each tap, flow rate data and pressure data.  In addition, sources are required to conduct monthly operational status checks of the equipment (e.g., physical appearance, pressure sensors, dampers, damper switches).
f  Daily monitoring includes stack emissions monitoring using a continuous opacity monitor if the source has an EAF equipped with a direct shell evacuation system (DEC) and uses a negative pressure baghouse and has not elected the alternative option.  In addition, the source is required to conduct fugitive emissions monitoring using a furnace static pressure monitoring device or by electing to perform shop opacity observations using a certified visible emissions observer, it the source has an EAF equipped with a DEC.
g  Sources are required to provide semiannual reports of opacity observations and operational values (i.e., furnace static pressure, fan motor amperes) that exceed or are below (i.e., flow rates) those established during the performance test, and of all shop opacity observations in excess of the emission limit.
h Submittal of performance test data through the EPA's CEDRI in ERT format is estimated to require 8 hours annually, includes keeping records of failures to meet the standards and the actions taken to minimize emissions.
i   We have assumed that the new source will equipped its EAFs with a DEC system and use a positive pressure baghouse, and therefore, will not be required to install a continuous opacity monitor (COMS).
j  We have assumed that approximately 51.7 percent of the respondents (or 46.53 respondents) will choose to comply with the fugitive emissions monitoring requirements by measuring the furnace static pressure continuously and 48.3 percent (43.47 respondents) will choose the alternative option of daily opacity shop observations by a certified visible emission observer couple with the use of bag leak detection systems (BLDS).
k  We have assumed that approximately 40 percent of respondents (36 respondents) use negative pressure baghouses.  Of these, 66.6 percent (23.98 respondents) use COMS to measure stack emissions and 33.4 percent (12.02 respondents) have elected to use the alternative option of using BLDS monitoring couple with visible emissions observations instead of using COMS.
l Totals have been rounded to 3 significant figures.  Figures may not add exactly due to rounding.

Assumptions

a  We have assumed that there are an annual average of 89 sources currently subject to the NSPS, subparts AA and AAa. We have further assumed there will be three new minimills over the three-year period of this ICR (1 new respondent per year) subject to subpart AAb. Therefore, the average number of respondents per year is estimated to be 90.
b  This cost is based on the following labor rates which incorporates a 1.6 benefits multiplication factor to account for government overhead expenses:  Managerial rate of $69.04 (GS-13, Step 5, $43.15 + 60%), Technical rate of $51.23 (GS-12, Step 1, $32.02 + 60%), and Clerical rate of $27.73 (GS-6, Step 3, $17.33 + 60%).  These rates are from the Office of Personnel Management (OPM) "2021 General Schedule" which excludes locality rates of pay.
c   We have assumed that 5 percent of the sources would repeat performance tests due to failure. We have assumed 1.64 baghouses per new facility based on collected information from existing sources (1.64 = 54 baghouses / 33 EAF facilities).
d  Method 5 test every 5 years on each new EAF control device after initial test at startup, 3 facilities. We have assumed 1.64 baghouses per new facility based on collected information from existing sources (1.64 = 54 baghouses / 33 EAF facilities).
e  Totals have been rounded to 3 significant figures.  Figures may not add exactly due to rounding.
