ENVIRONMENTAL PROTECTION AGENCY

NSPS/NESHAP for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 60, Subpart PPP and 40 CFR Part 63, Subpart NNN) (Renewal)

1. Identification of the Information Collection

1(a) Title of the Information Collection

NSPS/NESHAP for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 60, Subpart PPP and 40 CFR Part 63, Subpart NNN) (Renewal), EPA ICR Number 1160.15, OMB Control Number 2060-0114.

1(b) Short Characterization/Abstract

The New Source Performance Standards (NSPS) for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 60, Subpart PPP) were proposed on February 7, 1984; and promulgated on February 25, 1985. These regulations apply to existing facilities and new facilities with rotary spin (RS) wool fiberglass insulation manufacturing lines. New facilities include those that commenced construction, modification or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 60, Subpart PPP.

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 63, Subpart NNN) were proposed on March 31, 1997; promulgated on June 14, 1999; and amended on: April 20, 2006; July 29, 2015; December 26, 2017 (82 FR 60873); and December 28, 2020¹. These regulations apply to each new and existing glass melting furnace located at a wool fiberglass manufacturing facility; each new and existing bonded RS manufacturing line producing building insulation; and each new and existing flame attenuation (FA) manufacturing line that produces a bonded product. Plants that manufacture mineral wool from rock or slag are not subject to the rule, but they are subject to 40 CFR Subpart DDD, the National Emission Standards for Hazardous Air Pollutants for Mineral Wool Production. A facility that is determined to be an area source would not be subject to this NESHAP standard, but they are subject to a separate NESHAP (40 CFR Part 63, Subpart NN). New facilities include those that commenced either construction or reconstruction after November 25, 2011. This information is being collected to assure compliance with 40 CFR Part 60, Subpart PPP and 40 CFR Part 63, Subpart NNN.

In general, all NSPS and 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 NSPS and NESHAP.

Any owner/operator subject to the provisions of 40 CFR Part 60, Subpart PPP shall maintain a file containing these documents, and retain the file for at least two years following the generation date of such maintenance reports and records. Any owner/operator subject to the provisions of 40 CFR Part 63, Subpart NNN 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 required to be submitted electronically are submitted through the EPA's Central Data Exchange (CDX), using the Compliance and Emissions Data Reporting Interface (CEDRI), where the delegated state or local authority can review them. If there is no such delegated authority, the EPA regional offices can review them.  All other reports are sent to the delegated state or local authority. If there is no such delegated authority, the reports are sent directly to the EPA regional offices. The use of the term "Designated Administrator" throughout this document refers to the U.S. EPA or a delegated authority such as a state agency. The term "Administrator" alone refers to the U.S. EPA Administrator. 

The “Affected Public” are owners or operators of wool fiberglass insulation manufacturing plants. The “burden” to the Affected Public may be found at the end of this document in both Table 1a: Annual Respondent Burden and Cost – NSPS for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 60, Subpart PPP) (Renewal) and Table 1b: Annual Respondent Burden and Cost – NESHAP for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 63, Subpart NNN) (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 both Table 2a: Average Annual EPA Burden and Cost – NSPS for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 60, Subpart PPP) (Renewal), and Table 2b: Average Annual EPA Burden and Cost – NESHAP for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 63, Subpart NNN) (Renewal).There are approximately 37 wool fiberglass insulation manufacturing facilities, which are owned and operated by private industry. None of the facilities in the United States are owned by either state, local, or tribal entities or by the Federal government. They are all owned and operated by privately-owned, for-profit businesses. We assume that they will all respond to EPA inquiries. Based on our consultations with industry representatives, there is an average of one affected facility at each plant site and each plant site has only one respondent (i.e., the owner/operator of the plant site).

Over the next three years, approximately 37 respondents per year will be subject to these standards, and one additional respondent will become subject to these same standards (Subpart PPP) over the next three years. There are approximately 32 sources currently subject to 40 CFR Part 60, Subpart PPP, and 5 sources subject to 40 CFR Part 63, Subpart NNN. The projected increase of one new respondent anticipated to become subject to Subpart PPP and the decreased estimate of the number of sources subject to Subpart NNN is based on feedback received as a result of consultation with industry.

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.

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, particulate matter and hazardous air pollutant (HAP) emissions from wool fiberglass insulation manufacturing facilities either cause or contribute to air pollution that may reasonably be anticipated to endanger public health and/or welfare. Therefore, the NSPS and NESHAP were promulgated for this source category at 40 CFR Part 60, Subpart PPP, and 40 CFR Part 63, Subpart NNN.

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 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 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.

Additionally, the EPA is requiring electronic reporting for certain notifications or reports. For 40 CFR 63 Subpart NNN, the EPA is requiring that owners or operators of affected sources would submit electronic copies of initial notifications required in 40 CFR 63.9(b), notifications of compliance status required in 40 CFR 63.9(h), notifications of changes in information already provided required in 40 CFR 63.9(j), and performance test reports through the EPA's Central Data Exchange (CDX), using the Compliance and Emissions Data Reporting Interface (CEDRI). For the notifications required in 40 CFR 63.9(b) and 63.9(j), owners and operators would be required to upload a PDF of the required notifications.

CEDRI includes the Electronic Reporting Tool (ERT) software, which is used by facilities to generate electronic reports of performance tests. The EPA is also requiring that 40 CFR Part 63, Subpart NNN performance test reports be submitted through the EPA’s ERT.

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

The requested recordkeeping and reporting are required under 40 CFR Part 60, Subpart PPP and 40 CFR Part 63, Subpart NNN.

3(a) Non-duplication

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

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

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

An announcement of a public comment period for the renewal of this ICR was published in the Federal Register (87 FR 28047) on April 8, 2022. No comments were received on the burden published in the Federal Register for this renewal.

3(c) Consultations

The Agency has consulted industry experts and internal data sources to project the number of affected facilities and industry growth over the next three years. The primary source of information as reported by industry, in compliance with the recordkeeping and reporting provisions in these standards, is the Integrated Compliance Information System (ICIS). ICIS is EPA’s database for the collection, maintenance, and retrieval of compliance data for industrial and government-owned facilities. The growth rate for the industry is based on our consultations with the Agency’s internal industry experts. Approximately 38 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 the standards have been previously reviewed to determine the minimum information needed for compliance purposes. In developing this ICR, we contacted both the North American Insulation Manufacturers Association (NAIMA), at (703) 684-0084, and the Central States Insulation Association, at (888) 294-0084.

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 NAIMA responded to update the inventory of facilities subject to each regulation. Specifically, NAIMA provided that the number of facilities that are subject to Subpart NNN is five, not ten; while the number for Subpart PPP will increase by one due to the construction of a new facility.

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.

For 40 CFR Part 63 Subpart NNN, the respondents are required to maintain all records, including reports and notifications for at least five years. This is consistent with the General Provisions as applied to these standards. The EPA believes that the five-year records retention requirement is consistent with the Part 70 permit program and the five-year statute of limitations on which the permit program is based. The retention of records for five years allows EPA to establish the compliance history of a source, any pattern of non-compliance, and to determine the appropriate level of enforcement action. 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.

4. The Respondents and the Information Requested

4(a) Respondents/SIC Codes

The respondents to the recordkeeping and reporting requirements are wool fiberglass manufacturing plants. The United States Standard Industrial Classification (SIC) code for the respondents affected by these standards is SIC 3296, which corresponds to the North American Industry Classification System (NAICS) 327993 for Mineral Wool Manufacturing.

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 rule was recently amended to include additional electronic reporting provisions on December 28, 2020. Respondents are required to use the EPA’s Electronic Reporting Tool (ERT) to develop performance test reports and submit them through the EPA’s Compliance and Emissions Data Reporting Interface (CEDRI), which can be accessed through the EPA’s Central Data Exchange (CDX) (https://cdx.epa.gov/). The ERT is an application rather than a form, and the requirement to use the ERT is applicable to numerous subparts. The splash screen of the ERT contains a link to the Paperwork Reduction Act (PRA) requirements, such as the OMB Control Number, expiration date, and burden estimate for this and other subparts. Respondents are also required to submit electronic copies of notifications and certain reports through EPA’s CEDRI. The notification is an upload of their currently required notification in portable document format (PDF) file. For purposes of this ICR, it is assumed that there is no additional burden associated with the proposed requirement for respondents to submit the notifications and reports electronically.

Electronic copies of records may also be maintained in order to satisfy federal recordkeeping requirements. For additional information on the Paperwork Reduction Act requirements for CEDRI and ERT for this rule, see: https://www.epa.gov/electronic-reporting-air-emissions/paperwork-reduction-act-pra-cedri-and-ert.

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

5(a) Agency Activities

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

Agency Activities

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

Audit facility records.

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

5(b) Collection Methodology and Management

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

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

The records required by 40 CFR Part 60, Subpart PPP must be retained by the owner/operator for two years. The records required by 40 CFR Part 63, Subpart NNN 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. However, the impact on small entities (i.e., small businesses) was taken into consideration during the development of these regulations. Due to technical considerations involving the process operations and the types of control equipment employed, the recordkeeping and reporting requirements are the same for both small and large entities. The Agency considers these to be the minimum requirements needed to ensure compliance and, therefore, cannot reduce them further for small entities. To the extent that larger businesses can use economies of scale to reduce their burden, the overall burden will be reduced.

5(d) Collection Schedule

The specific frequency for each information collection activity within this request is shown at the end of this document in both Table 1a: Annual Respondent Burden and Cost – NSPS for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 60, Subpart PPP) (Renewal) and Table 1b: Annual Respondent Burden and Cost – NESHAP for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 63, Subpart NNN) (Renewal).

6. Estimating the Burden and Cost of the Collection

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

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

6(a) Estimating Respondent Burden

The average annual burden to industry over the next three years from these recordkeeping and reporting requirements is estimated to be 5,580 hours (Total Labor Hours from both Tables 1a & 1b below). This estimate includes 2,730 hours for 40 CFR Part 60, Subpart PPP, and 2,850 hours for 40 CFR Part 63, Subpart NNN. These hours are based on Agency studies and background documents from the development of the regulation, Agency knowledge and experience with the NSPS and NESHAP programs, the previously-approved ICR, and any comments received.

6(b) Estimating Respondent Costs

(i) Estimating Labor Costs

This ICR uses the following labor rates:

Managerial $157.61 ($75.05 + 110%)

Technical $123.94 ($59.02 + 110%)

Clerical $62.52 ($29.77 + 110%)

These rates are from the United States Department of Labor, Bureau of Labor Statistics, September 2021, “Table 2. Civilian Workers, by occupational and industry group.” The rates are from column 1, “Total compensation.” The rates have been increased by 110 percent to account for varying industry wage rates and the additional overhead business costs of employing workers beyond their wages and benefits, including business expenses associated with hiring, training, and equipping their employees.

(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

Capital/Startup vs. Operation and Maintenance (O&M) Costs
(A) Continuous Monitoring Device	(B) Capital/Startup Cost for One Respondent	(C) Number of New Respondents	(D) Total Capital/Startup Cost, (B X C)	(E) Annual O&M Costs for One Respondent	(F) Number of Respondents with O&M1	(G) Total O&M, (E X F)2
NSPS for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 60, Subpart PPP)
Particulate Matter Monitoring	$15,000	0.33	$4,950	$16,500	32.33	$533,445
NESHAP for Wool Fiberglass Manufacturing Plants (40 CFR Part 63, Subpart NNN)
Baghouse Leak Detection	$9,100	0	$0	$500	3.5	$1,750
Furnace Temperature Monitoring	$1,500	0	$0	$0	2.5	$0
Formaldehyde Emission Monitoring	$15,000	0	$0	$0	8.5	$0

Phenol, Methanol and Formaldehyde Testing4	$0	0	$0	$800	6.5	$5,200
		Total2	$5,000		Total2	$580,000

¹ In order to calculate O&M costs for 40 CFR Part 63, Subpart NNN, the estimates provided in column F were not based on the number of respondents but, instead, based on the total number of continuous monitoring devices that exist within the industry; some respondents may have more than one continuous monitoring device located at their facility. We assumed the number of continuous monitoring devices decreased proportionally with the number of sources.

² Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.

³ The 2015 Residual Risk and Technology Review (RTR) assumed 8 gas-fired furnaces at 5 facilities. Chromium compound testing is required annually with an estimated cost of $10,000 per test.

⁴ The 2015 RTR assumed 13 flame attenuation lines at 2 facilities. Phenol, methanol, and formaldehyde testing is required once every 5 years with an estimated cost of $4,000 per test. ($4,000 per test x (1 test / 5 years) = $800/yr).

The total capital/startup costs for this ICR are $5,000. This is the total of column D in the above table.

The total operation and maintenance (O&M) costs for this ICR are $580,000. 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 $585,000. These are the recordkeeping costs.

6(c) Estimating Agency Burden and Cost

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

The average annual Agency cost during the three years of the ICR is estimated to be $11,600.

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

Managerial $70.56 (GS-13, Step 5, $44.10 + 60%)

Technical $52.37 (GS-12, Step 1, $32.73 + 60%)

Clerical $28.34(GS-6, Step 3, $17.17 + 60%)

These rates are from the Office of Personnel Management (OPM), 2022 General Schedule, which excludes locality rates of pay. The rates have been increased by 60 percent to account for the benefit packages available to Federal government employees. Details upon which this estimate is based appear at the end of this document in both Table 2a: Average Annual EPA Burden and Cost – NSPS for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 60, Subpart PPP) (Renewal), and Table 2b: Average Annual EPA Burden and Cost – NESHAP for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 63, Subpart NNN) (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 38 existing respondents will be subject to these standards. Approximately 32 sources are currently subject to 40 CFR Part 60, Subpart PPP, and 5 sources are subject to 40 CFR Part 63, Subpart NNN. It is estimated that one additional respondent will become subject to Subpart PPP over the next three years. The overall average number of respondents, as shown in the table below, is 38 per year.

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

Number of Respondents
	Respondents That Submit Reports		Respondents That Do Not Submit Any Reports
Year	(A) Number of New Respondents 1	(B) Number of Existing Respondents	(C) Number of Existing Respondents that keep records but do not submit reports	(D) Number of Existing Respondents That Are Also New Respondents	(E) Number of Respondents (E=A+B+C-D)
1	1	37	0	0	38
2	0	38	0	0	38
3	0	38	0	0	38
Average	0.33	37.67	0	0	38

¹ New respondents include sources with constructed, reconstructed and modified affected facilities. We anticipate one additional new or reconstructed source becoming subject to the rule in the next three years (an average of 0.33 new respondents per year).

Column D is subtracted to avoid double-counting respondents. As shown above, the average Number of Respondents over the three-year period of this ICR is 38.

The total number of annual responses per year is calculated using the following table:

Total Annual Responses
(A) Information Collection Activity	(B) Number of Respondents	(C) Number of Responses	(D) Number of Existing Respondents That Keep Records But Do Not Submit Reports	(E) Total Annual Responses E=(BxC)+D

The number of Total Annual Responses is 76.

The total annual labor costs are $669,000 (rounded). This includes $327,000 for 40 CFR Part 60, Subpart PPP, and $342,000 for 40 CFR Part 63, Subpart NNN. Details regarding these estimates may be found below in both Table 1a: Annual Respondent Burden and Cost – NSPS for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 60, Subpart PPP) (Renewal), and in Table 1b: Annual Respondent Burden and Cost – NESHAP for Wool Fiberglass insulation Manufacturing Plants (40 CFR Part 63, Subpart NNN) (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 5,580 hours. This includes 2,730 hours for 40 CFR Part 60, Subpart PPP, and 2,850 hours for 40 CFR Part 63, Subpart NNN. Details regarding these estimates may be found below in both Table 1a: Annual Respondent Burden and Cost – Annual Respondent Burden and Cost – NSPS for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 60, Subpart PPP) (Renewal), and Table 1b: Annual Respondent Burden and Cost – NESHAP for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 63, Subpart NNN) (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 42 hours per response for 40 CFR Part 60, Subpart PPP, and 285 hours per response for 40 CFR Part 63, Subpart NNN.

The total annual capital/startup and O&M costs to the regulated entity are $580,000. This includes $533,000 (rounded) for 40 CFR Part 60, Subpart PPP and $47,000 for 40 CFR Part 63, Subpart NNN. 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 228 labor hours at a cost of $11,600 (rounded). The average annual Agency burden and cost is estimated to be 164 labor hours at a cost of $8,350 for 40 CFR Part 60, Subpart PPP, and 64 labor hours at a cost of $3,290 for 40 CFR Part 63, subpart NNN; see below for both Table 2a: Average Annual EPA Burden and Cost – NSPS for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 60, Subpart PPP) (Renewal), and Table 2b: Average Annual EPA Burden and Cost – NESHAP for Wool Fiberglass Insulation Manufacturing Plants (40 CFR Part 63, Subpart NNN) (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 a net adjustment decrease in burden from the most-recently approved ICR due to more accurate estimates of existing sources. The industry trade organization North American Insulation Manufacturers Association (NAIMA) commented in response to consultation that an estimate of five facilities subject to 40 CFR Part 63, Subpart NNN is more accurate than the previous estimate, while the previous estimate of facilities subject to Subpart PPP is increasing by one due to construction of a new facility. The labor cost per facility has increased due to updated labor rates from the most recent Bureau of Labor Statistics report (September 2021).

There is a net adjustment decrease in the operation and maintenance (O&M) costs as calculated in section 6(b)(iii) compared with the costs in the previous ICR, due to the decreased number of respondents subject to Subpart NNN based on the information provided by NAIMA. This offsets the increase in capital and O&M costs due to the addition of one facility subject to Subpart PPP.

This ICR also includes an adjustment decrease in the annual estimated hours to familiarize with regulatory requirements (Table 1b) to align with the typical time required for existing respondents to refamiliarize themselves with the NESHAP regulations each year.

6(g) Burden Statement

The annual public reporting and recordkeeping burden for this collection of information is estimated to average 42 hours per response for 40 CFR Part 60, Subpart PPP, and 285 hours per response for 40 CFR Part 63, Subpart NNN. ‘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.

Assumptions:

^a We have assumed that there are approximately 32 respondents, with 1 additional new or reconstructed source becoming subject to the rule in the next three years (an average of 0.33 new respondents per year).

^b This ICR uses the following labor rates: $157.61 per hour for Executive, Administrative, and Managerial labor; $123.94 per hour for Technical labor, and $62.52 per hour for Clerical labor. These rates are from the United States Department of Labor, Bureau of Labor Statistics, September 2021, “Table 2: Civilian Workers, by Occupational and Industry group.” The rates are from column 1, “Total Compensation.” The rates have been increased by 110 percent to account for varying industry wage rates and the additional overhead business costs of employing workers beyond their wages and benefits, including business expenses associated with hiring, training, and equipping their employees.

^c We have assumed that all existing respondents will each take one hour to re-familiarize with the regulatory requirements each year.

^d We assume that it will take each respondent 72 hours to complete initial performance tests.

^e We assume that 20 percent of respondents will have to repeat the initial performance tests due to failures.

^f We assume that each respondent will take two hours to prepare notification reports.

g We assume that each respondent will take four hours to prepare semiannual report.

^h We assume that 0.25 hours is required to record operating parameters.

ⁱ We assume that each respondent will enter operating parameters and emissions records 250 days per year.

j We assume that it will take one hour per year for each respondent to record startups, shutdowns, malfunctions, etc.

k Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.

1 The 2017 amendments include the following changes as part of the Agency’s residual risk and technology review (RTR): (1) for forming, cooling, and collection processes on bonded rotary spin (RS) lines, readopting emission limits for formaldehyde that were established in the 1999 rule, establishing new emission limits for methanol, and adding a work practice standard for phenol emissions; (2) for flame attenuation (FA) lines, revising the emission standards promulgated on July 29, 2015 by creating three subcategories of FA lines and establishing emission limits for formaldehyde and methanol emissions, and either emission limits or work practice standards for phenol emissions for each subcategory of FA line. The 2020 amendments added electronic reporting for notifications for area sources reclassifying to major sources and changes in information already provided for major sources reclassifying to area sources. The 2017 and 2020 amendments did not impose any new information collection burden.
