NSPS for Sewage Sludge Incineration Units (40 CFR Part 60, Subpart LLLL) (Renewal) 

1. Identification of the Information Collection

      1(a) Title of the Information Collection

NSPS for Sewage Sludge Incineration Units (40 CFR Part 60, Subpart LLLL) (Renewal), EPA ICR Number 2369.05, OMB Control Number 2060-0658. 

      1(b) Short Characterization/Abstract		

      The New Source Performance Standards (NSPS) for Sewage Sludge Incineration Units (40 CFR Part 60, Subpart LLLL) were proposed on October 14, 2010, and promulgated on March 21, 2011. These regulations apply to new and existing facilities with one or more sewage sludge incineration (SSI) units. New facilities are those that commenced construction after October 14, 2010 or commenced modification after September 21, 2011. Physical or operational changes made to the SSI unit to comply with the SSI Emission Guidelines at 40 CFR Part 60, Subpart MMMM do not qualify as a modification under this NSPS. This information is being collected to assure compliance with 40 CFR Part 60, Subpart LLLL.

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

--------------------------------------------------------------------------------
      There are approximately 8 SSI facilities subject to the regulation, which are owned and operated by municipalities and local government (aka: the "Affected Public"). We assume that they will all respond to EPA inquiries. The `burden' to the Affected Public may be found at the end of this document in Table 1: Annual Respondent Burden and Cost  -  NSPS for Sewage Sludge Incineration Units (40 CFR Part 60, Subpart LLLL) (Renewal). The `burden' to the Federal Government is attributed entirely to work performed by either Federal employees or government contractors and may be found at the end of this document in Table 2: Average Annual EPA Burden and Cost  -  NSPS for Sewage Sludge Incineration Units (40 CFR Part 60, Subpart LLLL) (Renewal). 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      Over the next three years, approximately 7 existing respondents per year will be subject to these standards. Over the next three-year period, EPA estimates a total of 2 new sources and 1 modified source will become subject to these same standards, for an average of 1 new source per year. The overall average number of respondents is 8 per year. Each SSI facility has an average of 6 incinerator units onsite. These estimates are based on EPA's 2016 SSI Inventory. The number of respondents has been updated from the prior ICR based on the estimated growth rate, as EPA identified no additional changes to industry growth or decline through consultations, public comment, or internal Agency knowledge. The estimated growth rate assumptions have also been retained for the three-year period of this ICR. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
       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), hydrogen chloride (HCl), carbon monoxide (CO), dioxin/furan, mercury (Hg), oxides of nitrogen (NOx), sulfur dioxide (SO2), cadmium, lead, and fugitive emissions from sewage sludge incineration units 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 LLLL.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      2(b) Practical Utility/Users of the Data
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The recordkeeping and reporting requirements in the 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 the standards are used to inform the Agency or delegated authority when a source becomes subject to the requirements of the 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, Subpart LLLL.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 (84 FR 19777) on May 6, 2019. 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 the standard, 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 8 respondents will be subject to these standards over the three-year period covered by this ICR. The number of respondents has been updated based on the estimated growth rate from the prior ICR.

      Industry trade associations 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 both the National Association of Clean Water Agencies (NACWA), at (202) 833-2672, and the Water Environment Federation, at (800) 666-0206. 

      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, the Deputy CEO of the NACWA confirmed that our estimates (6 existing sources in the first year and one new source per year) seemed reasonable. 
--------------------------------------------------------------------------------

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

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

      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. Section 60.4915(i)(2) requires that sources submit relative accuracy test audit data and performance test data (except opacity data) electronically to EPA's Central Data Exchange (CDX) by using the Electronic Reporting Tool (ERT) (https://www.epa.gov/electronic-reporting-air-emissions/electronic-reporting-tool-ert) or other compatible electronic spreadsheet. Only data collected using test methods compatible with ERT are subject to this requirement to be submitted electronically into EPA's WebFIRE database.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
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
Attend performance tests
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. 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. 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
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      There are no small entities (i.e., small businesses) affected by this regulation. This NSPS does not contain any provisions reserved exclusively for the benefit of small entities. However, the NSPS does contain provisions that reduce the impact on all regulated entities, which would include any small entities. The owner or operator is allowed to conduct performance tests once every three years to show compliance if certain criteria are met. Deviation reports are required only if there is a deviation, otherwise reporting is annual, and operating parameter monitoring is required instead of continuous emissions monitoring systems (CEMS) for all pollutants, except for CO. The Agency considers these to be the minimum requirements needed to ensure compliance. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 Sewage Sludge Incineration Units (40 CFR Part 60, Subpart LLLL) (Renewal).
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      Table 1, at the end of this document, 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 1,560 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	$66.62 (GS-13, Step 5, $41.64 + 60%)
--------------------------------------------------------------------------------
            Technical	$49.44 (GS-12, Step 1, $30.90 + 60%)
--------------------------------------------------------------------------------
            Clerical	$26.75 (GS-6, Step 3, $16.72 + 60%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These rates are from the Office of Personnel Management (OPM), 2019 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. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
            (ii) Estimating Capital/Startup and Operation and Maintenance Costs
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The type of industry costs associated with the information collection activities in the subject standard 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 the regulation. The annual operation and maintenance costs are the ongoing costs to maintain the monitors and other costs such as photocopying and postage.

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

  [a]  We assume that there are 7 existing SSI facilities with an average of 6 incinerator units. Burden estimates are based on a "per respondent" basis, not a "per unit" basis. We assume that there will be a total of 2 new sources and 1 modified source over the next three-year period, averaging to 1 new respondent per year. Estimates are based on EPA's 2016 SSI Inventory and adjusted based on the estimated growth rate. 
--------------------------------------------------------------------------------
  [b]  Based on estimated monitoring costs provided in regulatory support documentation.
--------------------------------------------------------------------------------
  [c]  Total estimated cost for initial stack test, including Method 5 (PM), Method 9 (opacity), Method 10 (CO), Method 26 (HCl), Method 29 (metals), Method 23 (CDD/CDF), Method 7E (NOx), and Method 6C (SO2). Existing facilities may test every three years if certain requirements are met, and it is assumed that all facilities would meet the requirements. Thus, on average 2.31 existing sources per year (7 x 0.33 = 2.31) perform annual testing following the initial performance test.
--------------------------------------------------------------------------------
  [d]  Assumed $100 for purchase of filing cabinet to store copy of rule, records, and report copies. 
--------------------------------------------------------------------------------
  [e]  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 $288,000. This is the total of column D    in the above table. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total operation and maintenance (O&M) costs for this ICR are $710,000. 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 $998,000. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 activities such 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 $15,400. 
--------------------------------------------------------------------------------

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

		Managerial	$66.62 (GS-13, Step 5, $41.64 + 60%)
		Technical	$49.44 (GS-12, Step 1, $30.90 + 60%)
		Clerical	$26.75 (GS-6, Step 3, $16.72 + 60%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These rates are from the Office of Personnel Management (OPM), 2019 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 Sewage Sludge Incineration Units (40 CFR Part 60, Subpart LLLL) (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 7 existing respondents will be subject to these standards. It is estimated that one additional respondent per year will become subject to these same standards due to either new construction or modification. The overall average number of respondents, as shown in the table below, is 8 per year. 
--------------------------------------------------------------------------------

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

  [a] Facilities may test every three years if certain requirements are met, and it is assumed most facilities would meet the requirements. However, all facilities must submit annual compliance reports. 
--------------------------------------------------------------------------------
  [b] We assume that 10 percent of the facilities would not have a qualified operator available for more than two weeks at least once a year. We further assume this would require only two corrective action summaries. 
--------------------------------------------------------------------------------
  [c] We assume that 10 percent of the existing facilities (7 * 0.1 = 0.7) have excess emissions and submit semiannual deviation reports.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The number of Total Annual Responses is 16. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total annual labor costs are $75,400. Details regarding these estimates may be found below in Table 1: Annual Respondent Burden and Cost  -  NSPS for Sewage Sludge Incineration Units (40 CFR Part 60, Subpart LLLL) (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 1,560 hours. Details regarding these estimates may be found below in Table 1: Annual Respondent Burden and Cost  -  NSPS for Sewage Sludge Incineration Units (40 CFR Part 60, Subpart LLLL) (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 98 hours per response.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The total annual capital/startup and O&M costs to the regulated entity are $998,000. 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 319 labor hours at a cost of $15,400; see below in Table 2: Average Annual EPA Burden and Cost  -  NSPS for Sewage Sludge Incineration Units (40 CFR Part 60, Subpart LLLL) (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
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      There is an increase in burden from the most recently-approved ICR as currently identified in the OMB Inventory of Approved Burdens. This increase is not due to any program changes. The increase in burden from the most recently-approved ICR is due to an increase in the number of respondents subject to the rule. The estimated number of existing respondents has increased from 4 in the previous ICR to 7 in this ICR, with an attendant increase in labor hours. The estimated number of new or modified sources becoming subject to the rule remains at an average of one per year. The "per respondent" costs of annual performance testing and CEMS/CPMS monitoring have remained the same, but the total O&M costs have increased from the previous ICR renewal due to the increase in the number of existing respondents complying with the requirements of the rule. The increase in the number of existing respondents results in an increase in O&M expenses and stack testing expenses of an additional $304,000 per year. The previous ICR reflected the burdens and costs associated with the initial activities for one facility, and those costs remain the same in this ICR. The labor rates for the respondents in this ICR have been revised to reflect that SSI facilities are owned by government entities and pay their employees wage rates as shown in Office of Personnel Management (OPM) General Schedule. Wage rates for both respondents and Agency personnel have been revised to the rates from the Office of Personnel Management (OPM), 2019 General Schedule. The regulations have not changed over the past three years and are not anticipated to change over the next three years. 
--------------------------------------------------------------------------------
      Several revisions were made to the calculation of respondent burden. The labor burden for facilities to familiarize with regulation requirements was revised from 40 hours per existing source per year to 40 hours for a new source and 4 hours for an existing source. This change more accurately reflects the burden that new and existing sources require to familiarize and re-familiarize with the rule. The `Number of Respondents' that will complete the annual refresher course was revised from 1 to 7 to reflect that this is an annual requirement for operators at existing sources, per 40 CFR 60.4825. While the previous ICR rounded up the number of respondents for the Status Report and Corrective Action Summary to a whole number, this ICR calculates these figures as fractions. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      One revision was made to the calculation of Agency burden. The labor burden for the regulatory agency to read and understand rule requirements, estimated at 40 hours for each existing respondent for each year, was removed. Any labor burden required for Agency personnel to either familiarize or re-familiarize themselves with the requirements of a particular regulation are already accounted for in the labor burden assigned for the other line items in the estimate of annual burden and costs.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      6(g) Burden Statement
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The annual public reporting and recordkeeping burden for this collection of information is estimated to average 98 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 assume there are 7 existing facilities with 6 incineration units each. Burden estimates are based on a "per respondent" basis, not a "per unit" basis. We assume that there will be a total of 2 new sources and 1 modified source over the next three-year period, averaging to 1 new respondent per year. Estimates are based on EPA's 2016 SSI Inventory. 
b  This ICR uses the following labor rates: $66.62 for managerial, $49.44 for technical,  and $26.75 for clerical labor. These rates are from the Office of Personnel Management (OPM), 2019 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]  One-time only costs for new sources.
[d]  Annual Costs for existing sources. Annual costs are not incurred until the second year of operation. 
[e]  Existing facilities may test every three years if certain requirements are met, and it is assumed that all facilities would meet the requirements. Thus, on average 2.31 existing sources per year (7 x 0.33 = 2.31) perform annual testing following the initial performance test.
[f]  Costs incurred by a facility regardless of the number of affected units at the plant.
[g]  We assume that 10 percent of the facilities would not have a qualified operator available for more than two weeks at least once a year. We further assume that this would require only two corrective action summaries.
[h]  We assume that 10 percent of the facilities would have an exceedance during the year.  
[i]  Totals are rounded to 3 significant figures. Figures may not add exactly due to rounding.

Assumptions:








[a]  We assume there are 7 existing facilities with 6 incineration units each. Burden estimates are based on a "per respondent" basis, not a "per unit" basis. We assume that there will be a total of 2 new sources and 1 modified source over the next three-year period, averaging to 1 new respondent per year. Estimates are based on EPA's 2016 SSI Inventory. 
[b]  This ICR uses the following labor rates: $66.62 for managerial, $49.44 for technical,  and $26.75 for clerical labor. These rates are from the Office of Personnel Management (OPM), 2019 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 EPA personnel attend 15 percent of the stack tests. New facilities do stack testing. Existing facilities may test every three years if certain requirements are met, and it is assumed that all facilities would meet the requirements. (((1 new facility + (7 existing facilities x 0.33)) x 0.15) = 0.5 tests observed per year)
[d]  Includes notification of construction, notification of start-up for new units, notification of initial performance test, and notification of initial CMS demonstration.
[e]  We assume four hours per state to write annual summary report.
[f]  Totals rounded to 3 significant figures. Figures may not add exactly due to rounding.
