NESHAP for Benzene Emissions from Benzene Storage Vessels and Coke Oven               By-Product Recovery Plants (40 CFR Part 61, Subparts L and Y) (Renewal) 

 Identification of the Information Collection

      1(a) Title of the Information Collection

NESHAP for Benzene Emissions from Benzene Storage Vessels and Coke Oven By-Product Recovery Plants (40 CFR Part 61, Subparts L and Y) (Renewal), EPA ICR Number 1080.16, OMB Control Number 2060-0185.

      1(b) Short Characterization/Abstract

      The NESHAP for Coke Oven By-Product Recovery Plants (40 CFR Part 61, Subpart L) were promulgated on September 14, 1989 (54 FR 38073) and amended on February 12, 1999 (64 FR 7458). These regulations apply to each of the following benzene emission sources at furnace and foundry coke by-product recovery plants: tar decanters, tar storage tanks, tar-intercepting sumps, flushing-liquor circulation tanks, light-oil sumps, light-oil condensers, light-oil decanters, wash-oil decanters, wash-oil circulation tanks, naphthalene processing, final coolers, final-cooler cooling towers, and equipment intended to operate in benzene service, including: pumps, valves, exhausters, pressure relief devices, sampling connection systems, open-ended valves or lines, flanges or other connectors, and other control devices or systems. The provisions of this subpart also apply to benzene storage tanks, BTX (benzene-toluene-xylene) storage tanks, light-oil storage tanks, and excess ammonia-liquor storage tanks at furnace coke by-product recovery plants. This information is being collected to assure compliance with 40 CFR Part 61, Subpart L.
      
      The NESHAP for Benzene Emissions from Benzene Storage Vessels (40 CFR Part 61, Subpart Y) were promulgated on September 14, 1989 (54 FR 38077) and amended on December 14, 2000 (65 FR 78268). These standards apply to each benzene storage vessel with a design storage capacity greater than or equal to 38 cubic meters (10,000 gallons). This subpart does not apply to: 1) storage vessels used for storing benzene at coke by-product facilities; 2) vessels permanently attached to motor vehicles --such as trucks, rail cars, barges or ships; and 3) pressure vessels designed to operate in excess of 204.9 kPa (29.72 psia) and without emissions  to the atmosphere. This information is being collected to assure compliance with 40 CFR Part 61, Subpart Y.

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

--------------------------------------------------------------------------------
      Any owner/operator subject to the provisions of this part shall maintain a file containing these documents and retain the file for at least five years following the generation date of such maintenance reports and records. All reports are sent to either the delegated state or local authority. If there is no such delegated authority, the reports are sent directly to the U.S. Environmental Protection Agency (EPA) regional office.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The "Affected Public" are owners or operators of benzene storage vessels and coke by-product recovery plants. The "burden" to the Affected Public may be found at the end of this document in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Benzene Emissions from Benzene Storage Vessels and Coke Oven By-Product Recovery Plants (40 CFR Part 61, Subparts L and Y) (Renewal). The "burden" to the Federal Government is attributed entirely to work performed by either Federal employees or government contractors and may be found at the end of this document in Table 2: Average Annual Estimated EPA Burden and Cost  -  NESHAP for Benzene Emissions from Benzene Storage Vessels and Coke Oven By-Product Recovery Plants (40 CFR Part 61, Subparts L and Y) (Renewal). There are approximately 9 respondents per year which will be subject to Subpart L, and an average of 4 respondents per year which will be subject to Subpart Y. None of the facilities in the United States are owned by state, local, tribal, 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 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 9 respondents per year will be subject to Subpart L, and an average of 4 respondents per year will be subject to Subpart Y. The number of respondents subject to Subpart L have been adjusted downwards from the prior ICR, based on consultations with industry trade groups that indicate consolidation within the industry. No additional respondents per year will become subject for the purpose of this ICR. New or reconstructed sources under NESHAP Subpart Y are subject to similar monitoring, reporting, and record-keeping requirements under the New Source Performance Standards (NSPS) for storage vessels at 40 CFR Part 60, Subpart Kb. To avoid double-counting, the burden associated with these new sources are not presented in this ICR. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The Office of Management and Budget (OMB) approved the currently-active ICR without any "Terms of Clearance". 

--------------------------------------------------------------------------------
2. Need for and Use of the Collection
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      2(a) Need/Authority for the Collection
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The EPA is charged under Section 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, benzene emissions from storage vessels and coke by-product recovery plants 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 61, Subparts L and Y. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      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 either the Agency or its 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 annual and 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 61, Subparts L and Y.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      3(a) Non-duplication
--------------------------------------------------------------------------------

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

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

--------------------------------------------------------------------------------
      An announcement of a public comment period for the renewal of this ICR was published in the Federal Register (84 FR 19777) on May 6, 2019. No comments were received on the burden published in the Federal Register for this renewal.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      3(c) Consultations

      The Agency has consulted industry experts and internal data sources to project the number of affected facilities and industry growth over the next three years. The primary source of information as reported by industry, in compliance with the recordkeeping and reporting provisions in 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 9 respondents per year will be subject to Subpart L, and an average of 4 respondents per year will be subject to Subpart Y over the three-year period covered by this ICR. The number of respondents subject to Subpart L have been adjusted downwards from the prior ICR, based on consultations with industry trade groups that indicate consolidation within the industry.

      Industry trade associations and other interested parties were provided an opportunity to comment on the burden associated with these standards as they were being developed and that these same standards have been reviewed previously to determine the minimum information needed for compliance purposes. In developing this ICR, we contacted both the American Coke and Coal Chemicals Institute, at (703) 795-3541, and the Association for Iron & Steel Technology, at (724) 814-3000.

      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, we received comments from the American Coke and Coal Chemicals Institute with a list of by-product recovery coke plants; based on the information provided, there are only 9 operating by-product recovery coke plants at the time of development of this ICR. We have incorporated this information into the current ICR.
--------------------------------------------------------------------------------

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

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

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

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

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

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

--------------------------------------------------------------------------------
      Any information submitted to the Agency for which a claim of confidentiality is made will be safeguarded according to the Agency policies set forth in Title 40, chapter 1, part 2, subpart B - Confidentiality of Business Information (CBI) (see 40 CFR 2; 41 FR 36902, September 1, 1976; amended by 43 FR 40000, September 8, 1978; 43 FR 42251, September 20, 1978; 44 FR 17674, March 23, 1979).
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      3(g) Sensitive Questions
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The reporting or recordkeeping requirements in these standards do not include sensitive questions.

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

--------------------------------------------------------------------------------
      Some of the respondents are using monitoring equipment that automatically records parameter data. Although personnel at the affected facility must still evaluate the data, internal automation has significantly reduced the burden associated with monitoring and recordkeeping at a plant site.
--------------------------------------------------------------------------------

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

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

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

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

--------------------------------------------------------------------------------
      EPA conducts the following activities in connection with the acquisition, analysis, storage, and distribution of the required information:
                               Agency Activities
Review notifications and reports, including performance test reports, and excess emissions reports, required to be submitted by industry.
Audit facility records.
Input, analyze, and maintain data in the Enforcement and Compliance History Online (ECHO) and ICIS.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      5(b) Collection Methodology and Management
--------------------------------------------------------------------------------

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

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

--------------------------------------------------------------------------------
      The majority of the respondents are large entities (i.e., large businesses). However,       the impact on small entities (i.e., small businesses) was taken into consideration during the development of the regulation. Due to technical considerations involving the process operations and the types of control equipment employed, the recordkeeping and reporting requirements are the same for both small and large entities. The Agency considers these to be the minimum requirements needed to ensure compliance and, therefore, cannot reduce them further for small entities. To the extent that larger businesses can use economies of scale to reduce their burden, the overall burden will be reduced.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The specific frequency for each information collection activity within this request is shown at the end of this document in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Benzene Emissions from Benzene Storage Vessels and Coke Oven By-Product Recovery Plants (40 CFR Part 61, Subparts L and Y) (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 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 1,730 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	$141.06 ($67.17+ 110%)  
--------------------------------------------------------------------------------
            Technical	$120.27 ($57.27 + 110%)
--------------------------------------------------------------------------------
            Clerical	$58.67 ($27.94 + 110%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The only costs to the regulated industry resulting from information collection activities required by the subject standard(s) are labor costs. There are no capital/startup or operation and maintenance costs.
--------------------------------------------------------------------------------
            (iii) Capital/Startup vs. Operation and Maintenance (O&M) Costs
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The only type of industry costs associated with the information collection activity in these regulations are labor costs. There are no capital/startup or operation and maintenance costs.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      6(c) Estimating Agency Burden and Cost
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The average annual Agency cost during the three years of the ICR is estimated to be $4,440. 
--------------------------------------------------------------------------------

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

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

--------------------------------------------------------------------------------
      These rates are from the Office of Personnel Management (OPM), 2019 General Schedule, which excludes locality rates of pay. The rates have been increased by 60 percent to account for the benefit packages available to Federal government employees. Details upon which this estimate is based appear at the end of this document in Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Benzene Emissions from Benzene Storage Vessels and Coke Oven By-Product Recovery Plants (40 CFR Part 61, Subparts L and Y) (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 9 existing respondents will be subject to Subpart L and 4 existing respondents will be subject to Subpart Y. It is estimated that no additional respondents per year will become subject to these regulations. The overall average number of respondents, as shown in the table below, is 9 per year for Subpart L and 4 per year for Subpart Y. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      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 1,730 hours. Details regarding these estimates may be found below in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Benzene Emissions from Benzene Storage Vessels and Coke Oven By-Product Recovery Plants (40 CFR Part 61, Subparts L and Y) (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 79 hours per response.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The total annual capital/startup and O&M costs to the regulated entity are $0. The cost calculations are detailed in Section 6(b)(iii), Capital/Startup vs. Operation and Maintenance (O&M) Costs.

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

--------------------------------------------------------------------------------
      There is an adjustment decrease in the total estimated burden as currently identified in the OMB Inventory of Approved Burdens. This decrease is not due to any program changes. Based on consultations with industry, the number of coke plants subject to Subpart L has been revised since the previous ICR, while the number of facilities subject to Subpart Y remains unchanged. The number of coke plants subject to Subpart L reflects a decrease in the number of operating coke by-product recovery plants. This change results in a decrease in burden hours and in the number of responses. Also, there is an adjustment in the labor burden in this ICR compared to the previous ICR due to the increase in labor costs over the past three years. The overall result is a decrease in burden. 
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The annual public reporting and recordkeeping burden for this collection of information is estimated to average 79 hours per response. `Burden' means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information either to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously-applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information.

Assumptions:
a. We have assumed that an average of 9 respondents per year will be subject to 40 CFR subpart L and an average of 4 respondents per year will be subject to 40 CFR subpart Y.  No new sources will become subject to the rule over the three-year ICR period.  Note that the burden for any new sources subject to subpart Y is included in the NSPS for storage vessels at 40 CFR part 60, subpart Kb.
b. This ICR uses the following labor rates: $120.27 for technical, $141.06 for managerial, and $58.67 for clerical labor.  These rates are from the United States Department of Labor, Bureau of Labor Statistics, June 2019, "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 have assumed that each respondent will take 0.5 hours to complete the annual maintenance inspection.
d. We have assumed that each respondent will take twelve hours twice per year to write semiannual emissions reports.
e. We have assumed that each respondent will take thirty-three hours four times per year to file and maintain records.
f. We have assumed that each respondent will take two hours twice per year to complete the performance evaluation for Method 21.
g. EFR - External Floating Roof. IFR - Internal Floating Roof. 
h. We believe that all vessels have been degassed and that all controls have been installed, as they were to be installed within ten years of promulgation.
[i][.] We have assumed that two percent of existing sources will request a delay of repair in the annual report.
[j.] We have assumed that no sources will select the option for a fixed roof vented to a control device, and thus have no quarterly reports of excess emissions.
k. Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.

Assumptions:
[a.] We have assumed that an average of 9 respondents per year will be subject to 40 CFR subpart L and an average of 4 respondents per year will be subject to 40 CFR subpart Y.  No new sources will become subject to the rule over the three-year ICR period.  Note that the burden for any new sources subject to subpart Y is included in the NSPS for storage vessels at 40 CFR part 60, subpart Kb.
[b.] This ICR uses the following labor rates: $49.44 for technical, $66.62 for managerial, and $26.75 for clerical labor.  These rates are from the Office of Personnel Management (OPM), 2019 General Schedule, which excludes locality rates of pay.  The rates have been increased by 60 percent to account for the benefit packages available to government employees.
[c.] We have assumed it will take the Agency four hours per respondent to review excess emissions and exemption reports twice per year.
[d.] IFR - Internal Floating Roof
[e.] We believe that all vessels have been degassed and that all controls have been installed, as they were to be installed within ten years of promulgation.
f. We have assumed that two percent of existing sources will request a delay of repair in the annual report.
[g.] We have assumed that no sources will select the option for a fixed roof vented to a control device, and thus have no quarterly reports of excess emissions.
[h.] Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.
