NSPS for Small Municipal Waste Combustors (40 CFR Part 60, Subpart AAAA) (Renewal) 

1. Identification of the Information Collection

      1(a) Title of the Information Collection

NSPS for Small Municipal Waste Combustors (40 CFR Part 60, Subpart AAAA) (Renewal), EPA ICR Number 1900.08, OMB Control Number 2060-0423. 

      1(b) Short Characterization/Abstract

      The New Source Performance Standards (NSPS) for Small Municipal Waste Combustors (40 CFR Part 60, Subpart AAAA) were proposed on August 30, 1999, and promulgated on December 6, 2000. These regulations apply to both existing facilities and new facilities with small municipal waste combustors (MWCs) that combust greater than 35 tons per day (tpd), but with less than 250 tpd of municipal solid waste. New facilities include those that commenced either construction, or modification or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 60, Subpart AAAA.

      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 five years following the generation date of such maintenance reports and records. All reports are sent to either 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 `burden' to the "Affected Public" may be found below in Table 1: Annual Respondent Burden and Cost  -  NSPS for Small Municipal Waste Combustors (40 CFR Part 60, Subpart AAAA) (Renewal). The Federal Government's `burden' is attributed entirely to work performed by either Federal employees or government contractors and may be found below in Table 2: Average Annual EPA Burden and Cost  -  NSPS for Small Municipal Waste Combustors (40 CFR Part 60, Subpart AAAA) (Renewal). There are approximately eight small MWC units (i.e. 8 sources), at six plants (i.e. 6 respondents), subject to these standards. One of the six plants is owned by a team of state and local governments, while the remaining five are owned by the private industry. We assume that they will all respond to EPA inquiries. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
       Based on our consultations with industry representatives, there are an average of 1.33 affected facilities at each plant site and each plant site has only one respondent (i.e., the owner/operator of the plant site).
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Over the next three years, approximately six respondents per year will be subject to these standards, and no additional respondents per year will become subject to these same standards. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      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, organics, metals, and acid gas emissions from small MWCs 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, Subpart AAAA.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 these emission standards. Continuous emission monitors are used to ensure compliance with these same standards at all times.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The notifications required in these 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 that the standards are being met. The performance test may also be observed.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The required annual and 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, Subpart AAAA.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      For reports required to be submitted electronically, the information is sent through the EPA's CDX, using CEDRI, where the appropriate EPA regional office can review it, as well as for state and local agencies that have been delegated authority. If a state or local agency has adopted under its own authority its own standards for reporting or data collection, adherence to those non-Federal requirements does not constitute duplication. 

	For all other reports, 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 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
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      An announcement of a public comment period for the renewal of this ICR was published in the Federal Register (87 FR 20847) on April 8, 2022. No comments were received on the burden published in the Federal Register for this renewal.  
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      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 6 respondents will be subject to these same standards over the three-year period covered by this ICR.

      Industry trade association(s) and other interested parties were provided an opportunity to comment on the `burden' associated with these standards as they were being developed and these same standards have been reviewed previously to determine the minimum information needed for compliance purposes. In developing this ICR, we contacted the following sources: 1) Solid Waste Association of North America (SWANA), at (240) 494-2237; and 2) the National Waste and Recycling Association (NWRA), at (202) 244-4700.

      It is our policy to respond after a thorough review of comments received since the last ICR renewal, as well as for those submitted in response to the first Federal Register notice. In this case, no comments were received. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 that 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.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These standards require the respondents to maintain all records, including reports and notifications for at least five years. This is consistent with the General Provisions as applied to these standards. The EPA believes that the five-year records retention requirement is consistent with the Part 70 permit program and the five-year statute of limitations on which the permit program is based. The retention of records for five years allows EPA to establish the compliance history of a source, any pattern of non-compliance and to determine the appropriate level of enforcement action. The EPA has found that the most flagrant violators have violations extending beyond five years. In addition, EPA would be prevented from pursuing the violators due to either the destruction or nonexistence of essential records.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The 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 and note the operating conditions under which compliance was achieved. 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. The EPA uses ICIS for tracking air pollution compliance and enforcement by local and state regulatory agencies, EPA regional offices, and EPA headquarters. The EPA and its delegated Authorities can edit, store, retrieve and analyze the data.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
       The records required by this regulation must be retained by the owner/operator for five years.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The majority of the respondents are large entities (i.e., large businesses). However, the impact on small entities (i.e., small businesses) was taken into consideration during the development of the regulation. Due to technical considerations involving the process operations and the types of control equipment employed, the recordkeeping and reporting requirements are the same for both small and large entities. 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.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The specific frequency for each information collection activity within this request is shown at the end of this document in Table 1: Annual Respondent Burden and Cost  -  NSPS for Small Municipal Waste Combustors (40 CFR Part 60, Subpart AAAA) (Renewal).
--------------------------------------------------------------------------------

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

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

--------------------------------------------------------------------------------
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 the subpart 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 record-keeping and reporting requirements is estimated to be 18,700 hours (Total Labor Hours from Table 1 below). These hours are based on Agency studies and background documents from the development of these regulations, 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	$157.61 ($75.05 + 110%) 
--------------------------------------------------------------------------------
            Technical	$123.94 ($59.02 + 110%)
--------------------------------------------------------------------------------
            Clerical	$62.52 ($29.77 + 110%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These rates are from the United States Department of Labor, Bureau of Labor Statistics, September 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 varying industry wage rates and the additional overhead business costs of employing workers beyond their wages and benefits, including business expenses associated with hiring, training, and equipping their employees.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      For public facilities, this ICR uses the following labor rates:
--------------------------------------------------------------------------------
      
      Managerial	$70.56 (GS-13, Step 5, $44.10 + 60%)
		Technical	$52.37 (GS-12, Step 1, $32.73 + 60%)
		Clerical	$28.34(GS-6, Step 3, $17.17 + 60%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These rates are from the Office of Personnel Management (OPM), 2022 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.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (ii) Estimating Capital/Startup and Operation and Maintenance Costs
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The type of industry costs associated with the information collection activities in the subject standard(s) 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 monitor(s) and such other costs as photocopying and postage.

      [a] We estimate that no additional facilities will become subject to this subpart over the next three years. 
--------------------------------------------------------------------------------
      [b] The estimated number of facilities with O&M costs includes the 8 existing small MWC units (at 6 plants).	
--------------------------------------------------------------------------------
      [c] 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 $0. This is the total of column D in the above table. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total operation and maintenance (O&M) costs for this ICR are $154,000. This is the total of column G. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The average annual cost for capital/startup and operation and maintenance costs to industry over the next three years of the ICR is estimated to be $154,000. These are the recordkeeping costs.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The only costs to the Agency are those costs associated with analysis of the reported information. The EPA's overall compliance and enforcement program includes such 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 $40,200. 
--------------------------------------------------------------------------------

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

		Managerial	$70.56 (GS-13, Step 5, $44.10 + 60%)
		Technical	$52.37 (GS-12, Step 1, $32.73 + 60%)
		Clerical	$28.34(GS-6, Step 3, $17.17 + 60%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These rates are from the Office of Personnel Management (OPM), 2022 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 Small Municipal Waste Combustors (40 CFR Part 60, Subpart AAAA).

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

--------------------------------------------------------------------------------
      Based on our research for this ICR, on average over the next three years, approximately 6 existing respondents will be subject to these standards. It is estimated that no additional respondents per year will become subject to these same standards. The overall average number of respondents, as shown in the table below, is 6 per year.
--------------------------------------------------------------------------------

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

  [a] New respondents include sources with constructed, reconstructed and modified affected facilities. We assume no new respondents will be subject to the rule in the next three years. 
--------------------------------------------------------------------------------
  [b] There is an average of 1.33 affected facility (i.e. sources or units) per respondent (i.e. plant). 
--------------------------------------------------------------------------------
   8 facilities / 6 plants = 1.33 facilities/plant (rounded). 
--------------------------------------------------------------------------------
  [c] Assumes a total of 2 semiannual excess emission reports (1 report for a privately-owned source and 1 report for a state/local government-owned source).
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The number of Total Annual Responses is 10. 
--------------------------------------------------------------------------------
      The total annual labor costs are $2,030,000. Details regarding these estimates may be found at the end of this document in Table 1: Annual Respondent Burden and Cost  -  NSPS for Small Municipal Waste Combustors (40 CFR Part 60, Subpart AAAA) (Renewal).

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

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

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

--------------------------------------------------------------------------------
      The total annual labor hours are 18,700 hours. Details regarding these estimates may be found below in Table 1: Annual Respondent Burden and Cost  -  NSPS for Small Municipal Waste Combustors (40 CFR Part 60, Subpart AAAA) (Renewal). 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      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 1,870 hours per response.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The total annual capital/startup and O&M costs to the regulated entity are $154,000. 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 787 labor hours at a cost of $40,200; see below in Table 2: Average Annual EPA Burden and Cost  -  NSPS for Small Municipal Waste Combustors (40 CFR Part 60, Subpart AAAA) (Renewal).
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      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
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The increase in burden from the most-recently approved ICR is due to an adjustment.  The adjustment increase in respondent burden from the most recently approved ICR is due to an increase in the number of respondents. The number of respondents reflects one new facility over the past three years. The increase is also due to the use of updated labor rates from the most- recent Bureau of Labor Statistics report (September 2021). There is an increase in the operation and maintenance (O&M) costs due to the increase in the number of respondents over the past three years. However, no additional respondents are predicted during the three-year period of this ICR. 
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The annual public reporting and recordkeeping burden for this collection of information is estimated to average 1,870 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.

ASSUMPTIONS








[a] We have assumed that the average number of existing respondents that will be subject to the rule will be 6. There will be no additional new sources that will become subject to the rule over the three-year period of this ICR. 
[b] This ICR uses the following labor rates for private sources: $157.61 per hour for Executive, Administrative, and Managerial labor; $123.94 per hour for Technical labor, and $62.52 per hour for Clerical labor. These rates are from the United States Department of Labor, Bureau of Labor Statistics, September 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 varying industry wage rates and the additional overhead business costs of employing workers beyond their wages and benefits, including business expenses associated with hiring, training, and equipping their employees.
[c] This ICR uses the following labor rates for public sources: Managerial rate of $70.56 (GS-13, Step 5, $44.10 + 60%), Technical rate of $52.37 (GS-12, Step 1, $32.73 + 60%), and Clerical rate of $28.34 (GS-6, Step 3, $17.17 + 60%). These rates are from the Office of Personnel Management (OPM), "2022 General Schedule" which excludes locality rates of pay. The rates have been increased by 60 percent to account for the benefit packages available to government employees. 
[d] There are an average of 1.33 affected facilities (i.e., sources or units) per respondent [8 facilities at 6 plants = 1.33 (Rounded)].
[e] Relative accuracy test audits (RATA) occur once per year for each affected facility (1 x 1.33 = 1.33).
[f] Relative accuracy audits (RAA) occur three times per year for each affected facility (3 x 1.33 = 4).
[g] Daily calibration and operation data occurs daily (365 x 1.33 = 485.5).
[h] RATA audits are performed for one of the four quarterly audits. RAA tests are performed for three of the four quarterly audits. Audits of the diluent monitor (O2 or CO2) are not required because tests on SO2 and CO monitors will incorporate the use of the diluent monitor.
[i] Assumes a total of 2 semiannual excess emission reports (1 report for a privately-owned source and 1 report for a state/local government-owned source). 
[j] Assumes 47 weeks of operation (90 percent availability) per year per facility.
[k] Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.

ASSUMPTIONS
[a] We have assumed that the average number of respondents that will be subject to the rule will be 6. There will be no additional new sources that will become subject to the rule over the three-year period of this ICR. 
[b] This cost is based on the following labor rates: Managerial rate of $70.56 (GS-13, Step 5, $44.10 + 60%), Technical rate of $52.37 (GS-12, Step 1, $32.73 + 60%), and Clerical rate of $28.34 (GS-6, Step 3, $17.17 + 60%). These rates are from the Office of Personnel Management (OPM), "2022 General Schedule" which excludes locality rates of pay. The rates have been increased by 60 percent to account for the benefit packages available to government employees. 
[c] Assumes a total of 2 excess emissions reports from all affected facilities.
[d] Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.
