NESHAP for Polyvinyl Chloride and Copolymers Production Area Sources (40 CFR Part 63, Subpart DDDDDD) (Renewal) 

1. Identification of the Information Collection

      1(a) Title of the Information Collection

NESHAP for Polyvinyl Chloride and Copolymers Production Area Sources (40 CFR Part 63, Subpart DDDDDD) (Renewal), EPA ICR Number 2454.05, OMB Control Number 2060-0684.
      
      1(b) Short Characterization/Abstract

      The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Polyvinyl Chloride and Copolymers Production Area Sources (40 CFR Part 63, Subpart DDDDDD) were proposed on May 20, 2011; and promulgated on April 17, 2012. These regulations apply to existing facilities and new PVC and copolymer production facilities that are area sources of hazardous air pollutants (HAP). This ICR includes burden estimates for area sources only. Major sources are regulated under NESHAP Subpart HHHHHHH, and their burdens are included in a separate ICR (OMB Control Number 2060-0666). New facilities include those that either commenced construction or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 63, Subpart DDDDDD.

      In general, all NESHAP standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in     the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to the NESHAP.

--------------------------------------------------------------------------------
	Any owner/operator subject to the provisions of this part shall maintain a file of these measurements and retain this file for at least five years following the date of such measurements, 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's  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's 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" includes PVC and copolymer area source facilities. The `burden'   to the Affected Public may be found below in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Polyvinyl Chloride and Copolymers Production Area Sources (40 CFR Part 63, Subpart DDDDDD) (Renewal). The `burden' to the Federal Government 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 Polyvinyl Chloride and Copolymers Production Area Sources (40 CFR Part 63, Subpart DDDDDD) (Renewal). There are approximately 3 facilities, which are owned and operated by the PVC and copolymer production industry. None of the 3 facilities in the United States are owned by either state, local, or tribal entities or the Federal government. They are all owned and operated by privately-owned, for-profit businesses. We assume that they will all respond to EPA enquiries.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
       Based on our consultations with industry representatives, there are 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 3 respondents per year will be subject to the standard, and no additional respondents per year will become subject to the standard. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      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 either 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 PVC and copolymer production area source facilities 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 DDDDDD.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      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 these emission standards. Continuous emission monitors are used to ensure compliance with these same 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 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.
--------------------------------------------------------------------------------

	Additionally, the EPA is requiring electronic reporting for certain notifications or reports. 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 change 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 DDDDDD 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 63, Subpart DDDDDD.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 (86 FR 19256) on April 13, 2021. 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 3 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 these standards have been reviewed previously to determine the minimum information needed for compliance purposes. In developing this ICR, we contacted both the Vinyl Institute (VI), at 202-765-2200, and Formosa Plastics, at 888-664-4040. The VI provided comments on the number of respondents, indicating closure of one facility, and stated that there are no new sources were being constructed as EPA re-evaluates the current standards.
      
      The VI suggested including capital costs for equipment replacements for PRDs, VC monitors, gasholders, and lab gas chromatographs (GC) at existing sources. Because capital costs are typically associated with new facilities, and no new facilities are expected during the 3-year period covered by this ICR renewal, we have not included capital costs in the burden estimate for this ICR renewal.  
      
      The VI suggested an increase to the operation and maintenance (O&M) costs for resin sampling and monitoring to account for two lab GCs per facility. We do not expect it to be necessary for a facility to maintain two GCs in order to demonstrate continuous compliance with the rule; therefore, we did not increase this O&M cost.
      
      The VI suggested an increase in O&M costs for stripped resin: Non-VC TOHAP testing, noting the use of outside contract lab services. Although a facility may choose to use contractor support, it is not required by the rule or considered to be necessary. Therefore, we did not increase this O&M cost.
      
      The VI suggested an increase to the O&M cost for non-vinyl chloride total HAP testing of wastewater. VI suggested to increase the cost to analyze samples from $650 per sample to $1500 per sample. However, the test method options are the same as those used for stripped resin testing where the cost remains unchanged at $650 per sample. We assume that $650 per sample is still reasonable for wastewater samples. Additionally, VI suggested an increase to this cost to allow for two samples per month. However, the rule only requires one grab sample per month to demonstrate continuous compliance with the rule. Therefore, we are not increasing the cost to account for two samples per month.
      
      The VI suggested an increase of the O&M cost for uncontrolled wastewater sampling based on five wastewater streams and two cooling water streams sampled per facility (7 streams total) and duplicate samples. While we adjusted the cost to account for 7 streams per facility as noted in section 6(b)iii below, we did not increase the cost to account for duplicate samples. Duplicate samples are not required in order to show continuous compliance with the rule.
      
      The VI suggested increasing the respondent hours per occurrence for familiarization with rule requirements for existing sources from 8 hours to 320 hours. Although we agree this cost is reasonable for new respondents, but because the rule requirements have not changed, we assume it will take 8 hours per existing respondent to read and understand the rule requirements. We assume minimal time is needed each year to refamiliarize with rule requirements and that new employees will need to familiarize themselves with rule requirements.
      
      The VI suggested to increase the respondent hours per occurrence associated with periodic performance testing, sampling, and reporting for equipment leaks from 43 hours to 83 hours, noting the use of an outside contractor. The VI also suggested to increase the O&M cost for equipment leak-testing based on some facilities "being sampled more frequently than others." There have been no changes to the equipment leak monitoring requirements since the 2012 final rule. Because the rule requirements have not changed, we do not expect most facilities would need an outside contractor to meet rule requirements. Therefore, we have not increased the estimate of 43 respondent hours per occurrence. Further, we anticipate facilities with equipment components would reflect improved control of leaks over time. Therefore, we have not increased this O&M cost.
      
      The VI provided an estimate of hours needed to perform annual audits. Audits are not required by 40 CFR 63, Subpart DDDDDD; therefore, we did not include hours for audits in the burden estimate.
      
      The VI suggested adding a burden estimate for pressure relief device (PRD) deviation reports as required by § 63.11142(f)(18). The VI provided an estimate of 4 hours to complete a PRD release report. We have not added an annual average burden for PRD deviation reports, because this is an occasional report and is not submitted at a regular frequency.
      
      The VI commented that the burden for recordkeeping for "Other Emission Sources" as required by § 63.11142(f)(19) does not appear to be reflected and provided an estimate of 1 hour for the compliance report and 1 hour to enter the information for recordkeeping purposes, for a gross total of 2 hours. We have not added hours for this requirement, because we expect the 10 hours estimated for records of other emission sources requirements already included in the burden estimate is sufficient for recordkeeping for all other emission sources.
      
      The VI also provided adjustments to the capital and operation and maintenance costs, monitoring, and recordkeeping, which we have incorporated where noted in this document.

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

--------------------------------------------------------------------------------
      3(d) Effects of Less-Frequent Collection
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Less-frequent information collection would decrease the margin of assurance that facilities are continuing to meet these standards. Requirements for information gathering and recordkeeping are useful techniques to ensure that good operation and maintenance practices are applied and emission limitations are met. If the information required by these standards was collected less-frequently, the proper operation and maintenance of control equipment and the possibility of detecting violations would be less likely.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      3(e) General Guidelines
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These reporting or recordkeeping requirements do not violate any of the regulations promulgated by OMB under 5 CFR Part 1320, Section 1320.5.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      3(f) Confidentiality
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Any information submitted to the Agency for which a claim of confidentiality is made will be safeguarded according to the Agency policies set forth in Title 40, chapter 1, part 2, subpart B - Confidentiality of Business Information (ICBI) (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
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
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 amended to include electronic reporting provisions on April 17, 2012. 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 both 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 will be no additional burden associated with the 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. ICIS is EPA's database for the collection, maintenance, and retrieval of compliance data for industrial and government-owned facilities. The EPA uses ICIS for tracking air pollution compliance and enforcement by local and state regulatory agencies, EPA regional offices, and EPA headquarters. The EPA and its delegated Authorities can edit, store, retrieve and analyze the data.
--------------------------------------------------------------------------------

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

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

--------------------------------------------------------------------------------
      There are no small entities (i.e., small businesses) affected by this regulation. The PVC NESHAP does not contain any provisions reserved exclusively for the benefit of small entities; however, there are provisions that reduce the impact on all regulated entities, which would include any small entities. Due to technical considerations involving the process operations and the types of control equipment employed, the recordkeeping and reporting requirements are the same for both small and large entities. The Agency considers these to be the minimum requirements needed to ensure compliance and, therefore, cannot reduce them further for small entities. To the extent that larger businesses can use economies of scale to reduce their burden, the overall burden will be reduced.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The specific frequency for each information collection activity within this request is shown at the end of this document in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Polyvinyl Chloride and Copolymers Production Area Sources (40 CFR Part 63, Subpart DDDDDD) (Renewal).
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      Table 1 documents the computation of individual burdens for the recordkeeping and reporting requirements applicable to the industry for the subpart included in this ICR. The individual burdens are expressed under standardized headings believed to be consistent with the concept of burden under the Paperwork Reduction Act. Where appropriate, specific tasks and major assumptions have been identified. Responses to this information collection are mandatory.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      6(a) Estimating Respondent Burden
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The average annual burden to industry over the next three years from these recordkeeping and reporting requirements is estimated to be 73,300 hours.  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	$153.55 ($73.12 + 110%) 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 $1,000,000. 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 $1,000,000.  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 $8,100. 
--------------------------------------------------------------------------------

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

		Managerial	$69.04 (GS-13, Step 5, $43.15 + 60%)
		Technical	$51.23 (GS-12, Step 1, $32.02 + 60%)
		Clerical	$27.73 (GS-6, Step 3, $17.33 + 60%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These rates are from the Office of Personnel Management (OPM), 2021 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  -  NESHAP for Polyvinyl Chloride and Copolymers Production Area Sources (40 CFR Part 63, Subpart DDDDDD) (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 3 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 3 per year.
--------------------------------------------------------------------------------

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

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

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

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

--------------------------------------------------------------------------------
      The total annual labor hours are 73,300 hours. Details regarding these estimates may be found below in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Polyvinyl Chloride and Copolymers Production Area Sources (40 CFR Part 63, Subpart DDDDDD) (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 8,144 hours per response.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The total annual capital/startup and O&M costs to the regulated entity are $1,000,000. 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 162 labor hours at a cost of $8,100; see below in Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Polyvinyl Chloride and Copolymers Production Area Sources (40 CFR Part 63, Subpart DDDDDD) (Renewal).
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      We assume that burdens for managerial tasks take 5% of the time required for technical tasks because the typical tasks for managers are to review and approve reports. Clerical burdens are assumed to take 10% of the time required for technical tasks because the typical duties of clerical staff are to proofread the reports, make copies and maintain records.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      6(f) Reasons for Change in Burden
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The decrease in burden from the most recently-approved ICR is due to four adjustments. There is an adjustment decrease in the total estimated burden as currently identified in the OMB Inventory of Approved Burdens. The adjustment decrease in burden from the most recently approved ICR is due to a decrease in the number of respondents. The most-recently approved ICR estimated 4 area source facilities; however, one facility has ceased operations, as reflected in the ICR for the most-recent proposed rule (85 FR 71490, November 9, 2020), which was previously submitted to OMB for approval. Therefore, this ICR renewal considers there to be 3 area source facilities. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The adjustment decrease is offset somewhat by the use of updated labor rates. This ICR uses labor rates from the most recent Bureau of Labor Statistics report (March 2021) to calculate respondent burden costs. The adjustment decrease is also offset by corrections to burden estimates for resin sampling, PRD electronic monitor review, gasholders, storage vessels, and ongoing inspections of bypasses and to the number of occurrences per year for recordkeeping requirements to more accurately reflect facility activities, as shown in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Polyvinyl Chloride and Copolymers Production Area Sources (40 CFR Part 63, Subpart DDDDDD) (Renewal).
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      There is a decrease in the operation and maintenance (O&M) costs as calculated in section 6(b)(iii) compared with the costs in the previous ICR. This decrease in costs is due to a decrease in the number of respondents and corrections made to the annual O&M costs for VC ambient monitoring and resin sampling and monitoring to more accurately reflect the number of monitors per facility and cost of monthly maintenance and service of a lab GC. The decrease is offset somewhat by corrections made to the cost estimates for uncontrolled wastewater testing and uncontrolled wastewater Non-VC TOHAP testing to more accurately reflect the number of waste streams sampled per facility.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The annual public reporting and recordkeeping burden for this collection of information is estimated to average 8,144 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.

[a] Assumes that, over the next three years, approximately 3 respondents per year will be subject to the standard, and no additional respondents per year will become subject to the standard. 
[b] Labor rates are $153.55 for managerial, $122.20 for technical, and $61.51 for clerical. These rates from the United States Department of Labor, Bureau of Labor Statistics, March 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 the benefit packages available to those employed by private industry.
[c] Costs apply only to newly-applicable sources.








[d] Cost incurred by a facility regardless of the number of affected units at the plant. Per VI's comments, this is performed monthly. We have assumed 10 hours per month for each process listed.
[e] There are 3 area sources in the affected source category.








[f]  It is assumed that performance testing for process vents will take 120 hours per occurrence initially.  The initial compliance and operating procedure development for continuous compliance and will take 8 hours.  The daily monitoring of parameters will take on avg 17.1 hr per facility per day over 350 day/yr. 
[g] Per VI's previous comments, it is assumed that performance testing for resins will take 4 hours per sample for 9 samples per facility, initially and daily (350 days per year). Pursuant to 40 CFR 63.11142(f)(16) and 63.11960(d)(2), we have increased the number of occurrences from 350 to 362 to account for 12 monthly samples.
[h] Estimated 1 uncontrolled stream and 1 wastewater stripper per facility. 1 wastewater stripper outlet is expected to require monthly testing;  5 uncontrolled stream will require annual testing (per facility).  It will take 4 hours per sample for 2 samples per stream.
[i] It is assumed that performance testing on heat exchangers will take 4 hours per sample for 2 samples per facility, initially and monthly. 


[j] For Equipment leaks, we estimate approx 10,000 components per facility and 5 minutes per component, plus additional time calibration of analytical device for a total of 850 hr per facility.  For continuous monitoring, we assume 1 hr is required per component for leak repair, if detected.  It was assumed that overall continuous compliace of leak monitoring will take 5% of the time with initial monitoring per month. 
[k] The Annualized PRD Electronic Monitor Review hours have been updated to include hours for corrective action for dishcarges and hours for replacement analysis. Per VI's comments, corrective action for discharge from a PRD would take 24 hours, and less than one PRD discharge event occurs per year in the entire industry. The number of hours for a discharge event is estimated to be 24/13 = 1.8 (rounded to 2) hours per facility. Per VI's comments, analysis for replacement of PRD monitors is estimated to take 24 hours per facility. Because the lifetime of a PRD monitor is expected to be 7 years, we do not expect the replacement alaysis to occur annually, and we have assumed that this occurs once every 3 years (24 hrs/3 years = 8 hours per year).
[l] Because the rule requirements have not changed for existing respondents, we assume it will take 8 hours per respondent to read and understand the rule requirements (1 hr for 8 employees). We assume minimal time is needed each year to refamiliarize with rule requirements for existing employees. We assume that new employees will need 320 hours to familiarize with rule requirements (40 hours for 8 employees).
[m] We have included this item based on comments previously provided by the Vinyl Institute. 
[n] Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.
[o] Per VI, 40 hrs per facility for traning, development, and implementation; and it will take 2 hrs per month to inspect car seals per facility. 
[p]Per VI's previous comments, this will require 24 hrs to evaluate compliance options, order materials, monitor installation, and developing O&M procedures. Note: there is only gasholder at an area source. This is assumed to be a one-time cost. Per VI's comments, facilities are performing this annually. We have assumed that annual updates to compliance options, order materials, monitor installation, and O&M procedures will require 5% of the time that was needed to meet the initial requirements.
[q]Per VI's previous comments, 40 hrs per facility to develop initial and ongoing compliance, inspection,and maintenance plans and procedures. This is assumed to be a one-time cost. Per VI's comments, facilities are performing this annually. We have assumed that annual updates will require 5% of the time that was needed to meet the initial requirements.
