NESHAP for Secondary Aluminum Production (40 CFR Part 63, Subpart RRR) (Renewal)

1. Identification of the Information Collection

      1(a) Title of the Information Collection

NESHAP for Secondary Aluminum Production (40 CFR Part 63, Subpart RRR) (Renewal),  EPA ICR Number 1894.09, OMB Control Number 2060-0433. 

      1(b) Short Characterization/Abstract

      The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Secondary Aluminum Production (40 CFR Part 60, Subpart RRR) were proposed on February 11, 1999, promulgated on March 23, 2000, and amended on the following dates: December 30, 2002 (67 FR 79808); September 3, 2004 (69 FR 53980); October 3, 2005 (70 FR 57513); December 19, 2005 (70 FR 75320); September 18, 2015 (80 FR 56700); and June 13, 2016 (81 FR 38085). These regulations apply to secondary aluminum production facilities that are major sources of hazardous air pollutants (HAP) either commencing construction, or reconstruction, after the date of proposal. This includes facilities that operate aluminum scrap shredders, thermal chip dryers, scrap dryers/delacquering kilns/decoating kilns, group 1 furnaces, group 2 furnaces, sweat furnaces, dross only furnaces, rotary dross coolers, and secondary aluminum processing units (SAPUs). The SAPUs include group 1 furnaces and in-line fluxers. The regulations also apply   to secondary aluminum production facilities that are area sources of HAP only with respect to emissions of dioxins/furans (D/F) from thermal chip dryers, scrap dryers/delacquering kilns/decoating kilns, group 1 furnaces, sweat furnaces, and SAPUs. New facilities include those that commenced construction, or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 63, Subpart RRR.

      The 2015 rule amendments included a requirement to report performance testing through the Electronic Reporting Tool (ERT); provisions allowing owners and operators to change furnace classifications; requirements to account for unmeasured emissions during compliance testing for group 1 furnaces that do not have add-on control devices; alternative compliance options for the operating and monitoring requirements for sweat furnaces; compliance provisions for hydrogen fluoride; provisions addressing emissions during periods of startup, shutdown, and malfunction (SSM); and other corrections and clarifications to the applicability, definitions, operating, monitoring and performance testing requirements. The 2016 rule amendments amended the 2015 rule to clarify requirements for initial performance tests and submittal of malfunction reports, provide an additional option for group 1 furnaces to account for unmeasured emissions during compliance testing, clarify what constitutes a change in furnace operating mode, and updates the Web addresses for the EPA's Electronic Reporting Tool (ERT) and Compliance and Emissions Data Reporting Interface (CEDRI). 
      
      In general, all NESHAP 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 NESHAP. 

--------------------------------------------------------------------------------
      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 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  -  NESHAP for Secondary Aluminum Production (40 CFR Part 63, Subpart RRR) (Renewal). The Federal Government's `burden' is attributed entirely to work performed by either Federal employees or government contractors and refer below in Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Secondary Aluminum Production (40 CFR Part 63, Subpart RRR) (Renewal). Note that this ICR merges the `burden' from both EPA ICR Number 1894.08 and ICR Number 2453.02, which is the final ICR for the 2015 final rule.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      There are approximately 161 secondary aluminum production facilities, which are owned and operated by the secondary aluminum production industry. This estimate includes 53 major sources of HAP. None of the 161 facilities in the United States are owned by either state, local, tribal, or Federal governments. They are all owned and operated by privately-owned, for-profit businesses. We assume that they will all respond to EPA inquiries. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Over the next three years, approximately 161 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 112 of the Clean Air Act, as amended, to establish standards of performance for each category or subcategory of major sources and area sources of hazardous air pollutants. These standards are applicable to new or existing sources of hazardous air pollutants and shall require the maximum degree of emission reduction. 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, HAP emissions from secondary aluminum production either cause or contribute to air pollution that may reasonably be anticipated to endanger public health and/or welfare. Therefore, the NESHAP were promulgated for this source category at 40 CFR Part 63, Subpart RRR.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 these 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 these standards are used to inform the Agency or its 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, that leaks are being detected and repaired, and that these 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, Subpart RRR.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      An announcement of a public comment period for the renewal of this ICR was published in the Federal Register (83 FR 24785) on May 30, 2018. 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 161 respondents will be subject to these 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 that these same standards have been reviewed previously to determine the minimum information needed for compliance purposes. In developing this ICR, we contacted both the Aluminum Association, at (703) 358-2960, and the North American Die Casting Association (NADCA), at (847) 808-3162. 

      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.  
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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. 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. 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.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
Electronic Reporting
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Some of the respondents are using monitoring equipment that automatically records parameter data. Although personnel at the affected facility must still evaluate the data, internal automation has significantly reduced the burden associated with monitoring and recordkeeping at a plant site.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The 2015 rule amendments included a requirement to report performance testing through the Electronic Reporting Tool (ERT). The ERT generates an electronic report package which will is submitted to the Compliance and Emissions Data Reporting Interface (CEDRI) and then archived to the EPA's Central Data Exchange (CDX). This requirement does not create any additional performance testing and will only apply to those performance tests conducted using test methods that are supported by the ERT. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (ii) Respondent Activities	
--------------------------------------------------------------------------------


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

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

--------------------------------------------------------------------------------
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 standard 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. 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 this regulation must be retained by the owner/operator for five years.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      A 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 below in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Secondary Aluminum Production (40 CFR Part 63, Subpart RRR) (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 12,400 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 NESHAP 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	$147.40 ($70.19+ 110%)  
--------------------------------------------------------------------------------
            Technical	$117.92 ($56.15 + 110%)
--------------------------------------------------------------------------------
            Clerical	$57.02 ($27.15 + 110%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These rates are from the United States Department of Labor, Bureau of Labor Statistics, June 2018, "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 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 other costs such as photocopying and postage.
--------------------------------------------------------------------------------

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

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

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

Assume that 34 percent of major sources (or 18 respondents) will use bag leak detectors on fabric filters with an average cost to industry at $291,111.  The actual cost of the bag leak detectors depends on the number of probes on the unit, and O&M costs for bag leak detectors is approximately $66,667.
 --------------------------------------------------------------------------------
All chlorine injection systems already have chlorine flow meters and the operation and maintenance costs are negligible.
 --------------------------------------------------------------------------------
Sources with fabric filters will be complying with the monitoring requirements through the use of a bag leak detector or visible emissions observations and not continuous opacity monitors.
 --------------------------------------------------------------------------------
An estimated 107 furnaces and 27 facilities would need temporary hoods installed every 5 years and testing conducted for a total capital cost of $17.3 million and a total annualized capital cost of $2.3 million. Total annualized cost per furnace would average $21,650 per year.
 --------------------------------------------------------------------------------
An estimated 8 affected facilities would incur a total annual O&M cost of $11,000 for measurement of hydrogen fluoride (HF) emissions.
 --------------------------------------------------------------------------------
Switching furnace classifications would result in total annual O&M costs for testing of $500,000/yr or, for an estimated 50 furnaces, a cost of $10,000 per furnace.
 --------------------------------------------------------------------------------
Temperature monitors will be installed at new sweat furnaces at a cost of $1,200. The O&M costs for temperature monitors are negligible.
 --------------------------------------------------------------------------------
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 $2,320,000. This is the total of column D in the above table. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total operation and maintenance (O&M) costs for this ICR are $1,790,000. This is the total of column G. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The average annual cost for both capital/startup and operation and maintenance costs             to industry over the next three years of the ICR is estimated to be $4,110,000. 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. 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 $83,300. 
--------------------------------------------------------------------------------

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

		Managerial	$65.71 (GS-13, Step 5, $41.07 + 60%) 
		Technical	$48.75 (GS-12, Step 1, $30.47 + 60%)
		Clerical	$26.38 (GS-6, Step 3, $16.49 + 60%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These rates are from the Office of Personnel Management (OPM), 2018 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 below in Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Secondary Aluminum Production (40 CFR Part 63, Subpart RRR) (Renewal).

      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 161 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 161 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 the respondents and the Agency are shown below in Tables 1 and 2, respectively, and summarized below. 
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The total annual labor hours are 12,400 hours (rounded). Details regarding these estimates may be found below in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Secondary Aluminum Production (40 CFR Part 63, Subpart RRR) (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 29 hours per response.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The total annual capital/startup and O&M costs to the regulated entity are estimated to be $4,110,000. 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 1,750 labor hours at a cost of $83,300; see below in Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Secondary Aluminum Production (40 CFR Part 63, Subpart RRR) (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
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Note this ICR merges the `burden' from EPA ICR Number 2453.02, which is the ICR for the 2015 final rule. There is also an adjustment decrease in the total estimated burden as currently identified in the OMB Inventory of Approved Burdens. The decrease is not due to any program changes. The change is due to correction of a mathematical error identified in the burden associated with the time required for facilities to refamiliarize with the regulatory requirements each year. The previous ICR stated that it would take each respondent one hour to read and understand the reporting requirements, but inadvertently included additional hours; the current ICR has been corrected to reflect one hour for this activity. The overall result is a slight decrease in burden hours. 
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The annual public reporting and recordkeeping burden for this collection of information is estimated to average 29 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 respondents that will be subject to this rule will be 161, of which 53 are major sources. There will be no additional new major or area sources over the three-year period of this ICR.
[b]  This ICR uses the following labor rates: $147.40 per hour for Executive, Administrative, and Managerial labor; $117.92 per hour for Technical labor, and $57.02 per hour for Clerical labor.  These rates are from the United States Department of Labor, Bureau of Labor Statistics, June 2018 "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 it will take each new respondent 54 hours to complete the task.  This burden cost is associated with the monitoring of all control equipment ensuring that respondents of new respondents meet the required specifications of this subpart.  No additional new major or areas sources are anticipated over the three-year period of this ICR.
[d]  We have assumed that it will take each respondent one hour to read and understand the reporting requirements. 
[e] It is assumed that new area sources will comply by meeting the equipment specifications rather than by conducting performance tests.  Respondents that are major sources are required to demonstrate initial compliance with the applicable emission limit, equipment, work practice, or operational standard for affected source or emission unit and report results in the notification of compliance status report. Since there are no new respondents estimated, the inital requirements do not apply. 
[f]  Since we have assumed that there will be no new sources over the next three-year period of this ICR, there will be no new sources conducting initial performance tests.  We have determined that respondents of new area sources will not be required to conduct emissions testing to show compliance with the emission limit, since it was determined that sweat furnaces sold in the United States now have an afterburner installed and meet the design residence time of 0.8 seconds or greater and an operating temperature of 1600 [o]F or greater.  All new respondents are required to submit for approval an operation, maintenance and monitoring plan for affected sources.
[g]  It is assumed that there will be no new sources requiring a waiver from the performance test requirements.
[h]  It is assumed that each respondent will take 8 hours to write semiannual report of excess emissions or no excess emissions.
[i]  An estimated 50 facilities would change furnace classifications once per year. 
[j]  It is assumed that it will take 1.5 hours for major source respondents to enter and transmit records.
[k]  It is assumed that it will take 0.5 hours for existing area source respondents to enter and transmit records.
[l]  We have assumed that it will take 4 hours to train new employees.
[m] We have assumed that it will take 0.25 hours to each new respondent to disclose information.
[n]  We have assumed that it will take 0.25 hours for each respondent to disclose information.
o 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 this rule will be 161, of which 53 are major sources. There will be no additional new major or area sources over the three-year period of this ICR.
[b]  This cost is based on the following hourly labor rates: $65.71 for Managerial (GS-13, Step 5, $41.07 + 60%), $48.75 for Technical (GS-12, Step 1, $30.47 + 60%) and $26.38 Clerical (GS-6, Step 3, $16.49 + 60%).  These rates are from the Office of Personnel Management (OPM) "2018 General Schedule" which excludes locality rates of pay. The rates have been increased by 60% to account for the benefit packages available to government employees.
[c]  We have assumed that all existing respondents are in compliance with the initial rule requirements.  It is further assumed that new sweat furnaces will comply by meeting the equipment specification than by conducting performance test.
[d] We have assumed that it will take 2 hours for each respondent to complete notification of compliance status.
[e]  We have assumed that each existing respondent will take 4 hours two times per year to complete the semiannual reports.
[f]  Assumes Agency will review all annual reports, including 4 HF tests/yr, 5 tests/yr for uncontrolled furnaces and 50 reports/yr for changing furnace classification.
g  Totals have been rounded to 3 significant figures.  Figures may not add exactly due to rounding.
