NESHAP for Halogenated Solvent Cleaners/Halogenated Hazardous Air Pollutants         (40 CFR Part 63, Subpart T) (Renewal)

1. Identification of the Information Collection

      1(a) Title of the Information Collection

NESHAP for Halogenated Solvent Cleaners/Halogenated Hazardous Air Pollutants (40 CFR Part 63, Subpart T) (Renewal), EPA ICR Number 1652.09, OMB Control Number 2060-0273.

      1(b) Short Characterization/Abstract

      The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Halogenated Solvent Cleaners/Halogenated Hazardous Air Pollutants were proposed on November 29, 1993 and promulgated on December 2, 1994. The NESHAP was amended on the following dates: June 5, 1995; December 11, 1998; July 13, 1999; August 19, 1999; and May 3, 2007. Collectively, these amendments corrected errors and clarified regulatory text, promulgated compliance extension dates, permanently exempted area batch cold solvent cleaning machines that use halogenated solvents from the Federal operating permit program, deferred Federal operating permit requirements for subject area halogenated solvent cleaning machines, provided compliance options for continuous web cleaning machines, and revised standards to further limit hazardous air pollutant (HAP) emissions. None of these amendments affected the respondent reporting or recording requirements promulgated in the final rule published on December 2, 1994. These regulations apply to each individual batch vapor, in-line vapor, in-line cold, and batch cold solvent cleaning machine that uses any solvent containing methylene chloride, perchloroethylene, 1, 1, 1-trichloroethane, trichloroethylene, carbon tetrachloride, chloroform,  or any combination of these halogenated HAP solvents, in a total concentration greater than 5 percent by weight, as a cleaning and/or drying agent. New facilities include those that commenced construction or reconstruction on or after December 2, 1994. This information is being collected to assure compliance with 40 CFR Part 63, Subpart T.

      In general, all NESHAP standards require initial notification reports, 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.     In the event that there is no such delegated authority, the reports are sent directly to the U.S. Environmental Protection Agency (EPA) regional office.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The "Affected Public" are owners or operators of solvent cleaning machines using       any solvent containing methylene chloride, perchloroethylene, 1, 1, 1-trichloroethane, trichloroethylene, carbon tetrachloride, chloroform, or any combination of these halogenated solvents in a concentration greater than 5 percent by-weight. The "burden" to the Affected Public may be found below in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Halogenated Solvent Cleaners/Halogenated Hazardous Air Pollutants (40 CFR Part 63, Subpart T) (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  -  NESHAP for Halogenated Solvent Cleaners/ Halogenated Hazardous Air Pollutants (40 CFR Part 63, Subpart T) (Renewal).
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Over the next three years, approximately 1,431 respondents per year will be subject to  these standards, and no additional respondents per year will become subject to these same standards. The estimate includes 1,180 batch and in-line vapor machines and 251 cold-cleaning machines.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 solvent cleaning machines 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 T.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      2(b) Practical Utility/Users of the Data
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The recordkeeping and reporting requirements in the standard 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 standard. Continuous emission monitors are used to ensure compliance with the standards at all times. During the performance test a record of the operating parameters under which compliance was achieved may be recorded and used to determine compliance in place of a continuous emission monitor.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The notifications required in the standard 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 63,      Subpart T.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 (80 FR 32116) on June 5, 2015. No comments were received on the burden published in the Federal Register.
--------------------------------------------------------------------------------
      3(c) Consultations

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

      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. In developing this ICR, we contacted: 1) the Halogenated Solvents Industry Alliance (HSIA) at<PHONE_NUMBER>; 2) the American Chemistry Council, at<PHONE_NUMBER>; 3) the Dry Cleaning and Laundry Institute in MD, at<PHONE_NUMBER>; and 4) the National Cleaners Association in New York City, at<PHONE_NUMBER>.

--------------------------------------------------------------------------------
      It is our policy to respond after a thorough review of comments received since the last ICR renewal, as well as 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 the 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 the 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.

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

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

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

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

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

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

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

--------------------------------------------------------------------------------
      Following notification of startup, the reviewing authority could inspect the source to determine whether the pollution control devices are properly installed and operated. Performance test reports are used by the Agency to discern a source's initial capability to comply with the emission standards, 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
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      According to the Final Rule (72 FR 25138): "The final rule is expected to affect 125 ultimate parent entities that will be regulated as major sources. Forty of the parent entities, or approximately one-third, are defined as small entities according to the SBA small business size standards."  Therefore, this ICR assumes that one-third of the affected facilities are small entities (e.g., small 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 record-keeping 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 Halogenated Solvent Cleaners/Halogenated Hazardous Air Pollutants (40 CFR Part 63, Subpart T) (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 not conduct or 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 48,000 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	$138.43 ($65.92+ 110%)
--------------------------------------------------------------------------------
            Technical	$106.45 ($50.69 + 110%)
--------------------------------------------------------------------------------
            Clerical	$52.77 ($25.13 + 110%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
These rates are from the United States Department of Labor, Bureau of Labor Statistics, September 2015, "Table 2. Civilian Workers, by occupational and industry group." The rates are from column 1, "Total compensation." The rates have been increased by 110 percent to account for the benefit packages available to those employed by private industry.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (ii) Estimating Capital/Startup and Operation and Maintenance Costs
--------------------------------------------------------------------------------

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

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

--------------------------------------------------------------------------------
      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 $1,010,000. 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 $1,010,000.
--------------------------------------------------------------------------------
      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 $208,000.
--------------------------------------------------------------------------------

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

		Managerial	$64.16 (GS-13, Step 5, $40.10 + 60%)
		Technical	$47.62 (GS-12, Step 1, $29.76 + 60%)
		Clerical	$25.76 (GS-6, Step 3, $16.10 + 60%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
These rates are from the Office of Personnel Management (OPM), 2016 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. Details upon which this estimate    is based appear below in Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Halogenated Solvent Cleaners/Halogenated Hazardous Air Pollutants (40 CFR Part 63, Subpart T) (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 1,431 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 1,431 per year. Of the 1,431 respondents, there are 1,180 batch vapor and in-line cleaning machines that have reporting requirements, and 251 batch cold cleaning machines that do not submit reports.
--------------------------------------------------------------------------------

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

      The total annual labor costs are $4,950,000. Details regarding these estimates may be found below in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Halogenated Solvent Cleaners/Halogenated Hazardous Air Pollutants (40 CFR Part 63, Subpart T) (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 below in Tables 1 and 2, respectively, and summarized below.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The total annual labor hours are 48,000 hours. Details regarding these estimates may be found below in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Halogenated Solvent Cleaners/Halogenated Hazardous Air Pollutants (40 CFR Part 63, Subpart T) (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 12 hours per response.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total annual capital/startup and O&M costs to the regulated entity are $1,010,000. 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 4,480 labor hours at a cost of $208,000. See below in Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Halogenated Solvent Cleaners/Halogenated Hazardous Air Pollutants (40 CFR Part 63, Subpart T) (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 adjustment increase in respondent labor hours in this ICR from the most recently approved ICR. This is due to assuming all existing sources will have to re-familiarize with the regulatory requirements each year. Additionally, there is a small decrease in the total capital and O&M cost due to the rounding of all calculated values to three significant digits.
--------------------------------------------------------------------------------
      6(g) Burden Statement
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The annual public reporting and recordkeeping burden for this collection of information is estimated to average 12 hours per response. "Burden" means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously-applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a valid OMB Control Number. The OMB Control Numbers for EPA regulations are listed at 40 CFR Part 9 and 48 CFR Chapter 15.

Assumptions:
[a.]  We estimate that an average of 1,431 existing respondents will be subject to the rule over the three-year period of this ICR.  Of this total, 1,180 respondents are subject to batch vapor and in-line cleaning machine requirements while 251 respondents are subject to batch cold cleaning machine requirements.  No new respondents are expected.
[b.]  This ICR uses the following labor rates: $106.45 for technical, $138.43 for managerial, and $52.77 for clerical labor.  These rates are from the United States Department of Labor, Bureau of Labor Statistics, September 2015, "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.
[c.]  We assume it will take 2 hours to familiarize with rule requirements.
[d.]  We estimate that idling emission or dwell test reports will require 80 technical hours, which are divided between the test report (30 hours) and the test itself (50 hours).
[e.]  We assume that 1,180 facilities are required to complete the annual compliance report.
[f.]  The burden of one quarterly and one semiannual exceedance report is included in the burden estimate for the annual report.
[g.]  We assume that 10 percent of 1,180 facilities are in exceedance at least one time per year (quarterly reporting).
[h.]  We assume that 90 percent of 1,180 facilities are not in exceedance (semiannual reporting).
[i.]  We assume that it will take 0.5 hours to familiarize with rule requirement. We assume this is a one-time activity because cold cleaning machines do not have ongoing reporting requirements.
[j.]  We assume that it will take 0.25 hours to write each report.
[k.]  Actual monitoring is conducted weekly, monthly or quarterly for specific control devices.  The estimated time is based on the typical control devices expected to be installed.
[l.]  We assume that 50 percent of the facilities will choose the standard equipment and will be required to conduct control device monitoring.
[m.]  We assume that 50 percent of the facilities will choose to do solvent consumption monitoring.
[n.]  We assume that it would take 1.2 hours per facility to record data.
[o.]  We assume that it would take 0.75 hours per facility to record solvent consumption data.
[p.]  We assume that no special training requirements are required.
[q.]  Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.

Assumptions:
[a.]  This ICR uses the following labor rates: $47.62 for technical, $64.16 for managerial, and $25.76 for clerical labor.  These rates are from the Office of Personnel Management (OPM), 2016 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.
[b.]  We assume that it will take 8 hours to review performance test results.
[c.]  All facilities are expected to submit annual compliance reports summarizing either solvent consumption data or monitoring results for each cleaning machine.
[d.]  The burden of one quarterly and one semiannual exceedance report is included in the burden estimate for the annual report.
[e.]  We assume that 10 percent of 1,180 facilities are in exceedance at least one time per year.
[f.]  We assume that 90 percent of 1,180 facilities are not in exceedance.
[g.]  Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.
