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

1.  Identification of the Information Collection

      1(a)  Title of the Information Collection

NESHAP for Benzene Emission from Benzene Storage Vessels and Coke By-Product Recovery Plants (40 CFR Part 61, Subparts L and Y) (Renewal), EPA ICR Number 1080.14, OMB Control Number 2060-0185

      1(b)  Short Characterization/Abstract

      The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Benzene Emission from Benzene Storage Vessels and Coke By-Product Recovery Plants (40 CFR part 61, subpart L) were promulgated on September 14, 1989 (54 FR 38073) and amended on: December 15, 1989 (54 FR 51699); April 13, 1990 (55 FR 14037); September 14, 1990 (55 FR 38073); September 19, 1991 (56 FR 47406); February 12, 1999 (64 FR 7458); October 17, 2000 (65 FR 61744); and December 14, 2000.  These regulations apply to each of the following 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 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 the regulations published at 40 CFR part 61, subpart Y were promulgated on September 14, 1989 (54 FR 38077) and amended on December 11, 1989 (54 FR 50887); October 17, 2000 (65 FR 61744); and December 14, 2000 (65 FR 78268).  The standard applies to each benzene storage vessel with a design storage capacity greater than or equal to 38 cubic meters (10,000 gallons).  Storage vessels with a design storage capacity below 38 cubic meters (10,000 gallons) are exempt.  Also exempt are storage vessels used for storing benzene at coke by-product facilities; vessels permanently attached to motor vehicles such as trucks, rail cars, barges or ships; and 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.
      
      The monitoring, reporting, and record keeping burden for owners and operators of new or reconstructed sources subject to subpart Y is included separately under the New Source Performance Standards (NSPS) for storage vessels at 40 CFR part 60, subpart Kb, which have similar monitoring, reporting, and record-keeping requirements.  To avoid double-counting, the "burden" associated with new sources is not presented in this ICR.
      
      In general, all NESHAP standards require initial notification reports, performance tests, and periodic reports by the owners/operators of the affected facilities.  They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative.  These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NESHAP.
      
--------------------------------------------------------------------------------
      Any owner/operator subject to the provisions of this part shall maintain a file of these measurements, and retain the file for at least two years following the date of such measurements, maintenance reports, and records.  All reports are sent to the delegated state or local authority.   In the event that there is no such delegated authority, the reports are sent directly to the U. S. Environmental Protection Agency (EPA) regional office.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Over the next three years, an average of 17 respondents per year will be subject to subpart L, and an average of 4 respondents per year will be subject to subpart Y.  No additional respondents per year will become subject to either standard.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The Office of Management and Budget (OMB) approved the currently active ICR without any "Terms of Clearance."
--------------------------------------------------------------------------------
      
	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 below in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Benzene Emission from Benzene Storage Vessels and Coke 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.  This burden may be found below in Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Benzene Emission from Benzene Storage Vessels and Coke By-Product Recovery Plants (40 CFR Part 61, Subparts L and Y) (Renewal).

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

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

--------------------------------------------------------------------------------
      The EPA is charged under Section 112 of the Clean Air Act, as amended, to establish standards of performance for each category or subcategory of major sources and area sources of hazardous air pollutants.  These standards are applicable to new or existing sources of hazardous air pollutants and shall require the maximum degree of emission reduction.  In addition, section 114(a) states that the Administrator may require any owner/operator subject to any requirement of this Act to: 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (A) Establish and maintain such records; (B) make such reports; (C) install, use, and maintain such monitoring equipment, and use such audit procedures, or methods; (D) sample such emissions (in accordance with such procedures or methods, at such locations, at such intervals, during such periods, and in such manner as the Administrator shall prescribe); (E) keep records on control equipment parameters, production variables or other indirect data when direct monitoring of emissions is impractical; (F) submit compliance certifications in accordance with Section 114(a)(3); and (G) provide such other information as the Administrator may reasonably require.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      In the Administrator's judgment, 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 NESHAPs 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 the emission standards.  Continuous emission monitors are used to ensure compliance with the standards at all times.  During the performance test, a record of the operating parameters under which compliance was achieved may be recorded and used to determine compliance in place of a continuous emission monitor.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The notifications required in the 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, that leaks are being detected and repaired, and 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 (78 FR 35023) on June 11, 2013.  No comments were received on the burden published in the Federal Register.
--------------------------------------------------------------------------------

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

      The Agency's industry experts have been consulted, and the Agency's internal data sources and projections of industry growth over the next three years have been considered.  The primary source of information as reported by industry, in compliance with the recordkeeping and reporting provisions in the standard, is the Online Tracking Information System (OTIS) which is operated and maintained by the EPA Office of Compliance. OTIS is the EPA database for the collection, maintenance, and retrieval of all compliance data.  
      
      Consultations with industry representatives (i.e., respondents) were conducted to determine if there is any way for EPA to reduce the recordkeeping and reporting burden or improve the language in the standards to make it easier to comply.  In developing this ICR,   EPA contacted: 1) the American Coke and Coal Chemicals Institute, at (202) 452-7198; and      2) the American Iron and Steel Institute, at (202) 452-7122.

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

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

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

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

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

--------------------------------------------------------------------------------
      Also, regulatory agencies in cooperation with the respondents continue to create reporting systems to transmit data electronically.  However, electronic reporting systems are still not widely used.  At this time, it is estimated that approximately 10 percent of the respondents use electronic reporting.
--------------------------------------------------------------------------------

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


--------------------------------------------------------------------------------
Respondent Activities

--------------------------------------------------------------------------------
Read instructions.

--------------------------------------------------------------------------------
Install, calibrate, maintain, and operate Continuous Monitoring Systems (CMS) for opacity, or for pressure drop and liquid supply pressure for closed systems, barrier fluid degassing systems, closed-vent systems to a control device, closed-purge systems to a control device, and seal systems, by monitoring equipments to repair. (40 CFR part 61, Subpart L only) 

--------------------------------------------------------------------------------
Perform initial performance test, Reference Method 21 test, and repeat performance tests if necessary. (40 CFR part 61, Subpart L only)

--------------------------------------------------------------------------------
Write the notifications and reports listed above.

--------------------------------------------------------------------------------
Enter information required to be recorded above.

--------------------------------------------------------------------------------
Submit the required reports developing, acquiring, installing, and utilizing technology and systems for the purpose of collecting, validating, and verifying information.

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

--------------------------------------------------------------------------------
Develop, acquire, install, and utilize technology and systems for the purpose of 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.

--------------------------------------------------------------------------------
Transmit, or otherwise disclose the information.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Currently sources are using monitoring and reporting equipment that provide parameter data in an automated way (e.g., continuous parameter monitoring system).  Although personnel at the source still need to evaluate the data, this type of monitoring equipment has significantly reduced the burden associated with monitoring and recordkeeping. 
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
Observe initial performance tests and repeat performance tests, if necessary.

--------------------------------------------------------------------------------
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 Online Tracking Information System (OTIS).
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      Information contained in the reports is entered into OTIS which is operated and maintained by EPA's Office of Compliance.  OTIS is EPA's database for the collection, maintenance, and retrieval of compliance data for approximately 125,000 industrial and government-owned facilities.  EPA uses the OTIS for tracking air pollution compliance and enforcement by local and state regulatory agencies, EPA regional offices and EPA headquarters.  EPA and its delegated Authorities can edit, store, retrieve and analyze the data.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
       The records required by these regulations must be retained by the owner/operator for two years.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      A 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  below in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Benzene Emission from Benzene Storage Vessels and Coke 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.  Wherever appropriate, specific tasks and major assumptions have been identified.  Responses to this information collection are mandatory.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The Agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB Control Number.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The average annual burden to industry over the next three years from these recordkeeping and reporting requirements is estimated to be 3,193 hours (see 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 NESHAPs 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	$123.04 ($58.59+ 110%)
--------------------------------------------------------------------------------
            Technical	$101.22 ($48.20 + 110%)
--------------------------------------------------------------------------------
            Clerical	$51.18 ($24.37 + 110%)

These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 2013, "Table 2. Civilian Workers, by occupational and industry group."  The rates are from column 1, "Total compensation."  The rates have been increased by 110 percent to account for the benefit packages available to those employed by private industry.

             (ii)  Estimating Capital/Startup and Operation and Maintenance Costs
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The only costs to the regulated industry resulting from information collection activities required by the subject standards are labor costs.  There are neither capital/startup nor 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 the 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 activities such as the examination of records maintained by the respondents, periodic inspection of sources of emissions, and the publication and distribution of collected information. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The average annual Agency cost during the three years of the ICR is estimated to be $7,966.  
--------------------------------------------------------------------------------

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

		Managerial	$62.27 (GS-13, Step 5, $38.92 + 60%)
		Technical	$46.21 (GS-12, Step 1, $28.88 + 60%)
		Clerical	$25.01 (GS-6, Step 3, $15.63 + 60%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
These rates are from the Office of Personnel Management (OPM), 2013 General Schedule, which excludes locality, rates of pay.  The rates have been increased by 60 percent to account for the benefit packages available to government employees.  Details upon which this estimate is based appear below in Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Benzene Emission from Benzene Storage Vessels and Coke 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, approximately 17 existing respondents will be subject to subpart L and 4 existing respondents will be subject to subpart Y on average over the next three years.  No additional respondents will become subject to either subpart on an annual basis.  Once again, the overall average number of respondents, as shown in the table below, is 17 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(f)  Reasons for Change in Burden
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      There is an increase in burden from the most recently approved ICR.  This increase is not due to any program changes; it is the result of adding the labor burden associated with subpart Y.  The most-recently approved ICR only reflected the burden associated with subpart L, while this ICR reflects the total burden associated with subparts L and Y.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      For subpart L, note that the labor burden between this ICR and the most-recently approved ICR is virtually identical (there is an increase of 1 hour, but it is due to differences in rounding).  However, there is an increase in Respondent and Agency burden costs.  This increase is due to the use of updated labor rates.  This ICR references labor rates from the Bureau of Labor Statistics to calculate respondent burden costs and references labor rates from OPM to calculate Agency burden costs.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The annual public reporting and recordkeeping burden for this collection of information is estimated to average 84 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.
--------------------------------------------------------------------------------

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

EFR - External floating roof
IFR - Internal floating roof

Assumptions:
[a.] We have assumed that an average of 17 respondents per year will be subject to 40 subpart L and an average of 4 respondents per year will be subject to 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: $101.22 for technical, $123.04 for managerial, and $51.18 for clerical labor.  These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 2013, "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.] 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.
[h.] We have assumed that two percent of existing sources will request a delay of repair in the annual report.
[i.] 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.

IFR - Internal floating roof
N/A - Not Applicable

Assumptions:
[a.] We have assumed that an average of 17 respondents per year will be subject to 40 subpart L and an average of 4 respondents per year will be subject to 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: $46.21 for technical, $62.27 for managerial, and $25.01 for clerical labor.  These rates are from the Office of Personnel Management (OPM), 2013 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 exception reports twice per year.
[d.] 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.
[e.] We have assumed that two percent of existing sources will request a delay of repair in the annual report.
[f.] 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.
