**1. Identification of the Information Collection**  **1(a) Title of the Information Collection** NSPS for Storage Vessels for Petroleum L iquids for which Construction, Reconstruction or Modification Commenced After June 11, 1973 , and Pr ior to May 19, 1978 (40 CFR Part 60, Subpart K) (Renewal) , EPA I CR Number 1797.05, OMB Control Number 2060

- 0442 **1(b) Short Characterization/Abstract** The New Source Performance Standards (NSPS) for Storage Vessels for Petroleum Li quids for which Construction, Reconstruction or Mod ification Commenced After June 11, 1973 , and P rior to May

19, 1978 , were proposed on June 11, 1973, and promulgated on March 8, 1974. These regulations apply to facilities that store petroleum liquids in storage vessels with a storage capacity

greater than 151,416 liters (40,000 gallons) including: storage vessels with capacity greater than 151,416 liters (40,000 gallons) but not exceeding 246,052 liters (65,000 gallons), and where construction or modification commenced after March 8, 1974, and prior to May 19, 1978; and storage vessels that have a capacity greater than 246,052 liters (65,000 gallons), and where construction or modification commenced after June 11, 1973, and prior to May 19, 1978. Facilities that are not subject to these standards are stor age vessels of petroleum or condensate stored, processed, and/or treated at a drilling and production facility prior to custody transfer. This information is being collected to assure compliance with these regulations

. The number of respondents for this renewal of the I CR is assumed to be 220. It is further assumed that there is an average of 25 storage vessels per respondent. These assumptions are based on the active I CR data. This is appropriate due to the very slow growth of the petroleum refining and coal products manufacturing industries which are affected by the NSPS subpart K rule. This number was originally obtained from EPA databases, consultation with EPA regional staff and an EPA contractor providing support to the Office of Enforcement and Compliance Assurance. The overall burden imposed on the regulated industry is 769 hours, at a total estimated cost of $ 7 2,750

. The Office of Management and Budget (OMB) approved the currently active information collection request (I CR) without any “ Terms of Clearance. ”2

**2. Need for and Use of the Collection 2(a) Need/Authority for the Collection**  The EPA is charged under Section 111 of the Clean Air Act (CAA), as amended, to establish standards of performance for new stationary sources that reflect: . . . application of the best technological sy stem of continuous emissions reduction which (taking into consideration the cost of achieving such emissions reduction, or any nonair quality

health and environmental impact and energy requirements) the Admi nistrator determines has been adequately demonstrated. Section 111(a)(l) The Agency

refers to this charge as selecting the best demonstrated technology (BDT). Section 111 also requires that the Administrator review and, if appropriate, revise such stan dards every four years. In addition, section 114(a) states that the Administrator may require any

owner or 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 a manner as the Administrator shall pres cribe); (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.
Inthe Administrator's judgment, volatile organic compounds (VOCs) emissions from storage vessels for petroleum liquids cause or contribute to air pollution that may reasonably

be anticipated to end anger public health or welfare. Therefore, the NSPS were promulgated for this source category

at 40 CFR part 60, subpart K. **2(b) Practical Utility/Users of the Data** The control of emissions of volatile organic compounds from storage vessels for petrole um liquids requires not only the installation of properly designed equipment, but also the operation and maintenance of that equipment. Emissions of volatile organic compounds from these vessels for petroleum liquids are the result of operation of the aff ected facilities. The subject standards are achieved by the reduction of volatile organic compound emissions using vapor recovery , floating roof, or their equivalent. The notifications required in the applicable regulations are used to inform the Agency or delegated authority when a source became subject3

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 and the regulations are being met . The information generated by the monitoring, recordkeeping and reporting requirements described in this I CR is used by the Agency

to ensure that facilities affected by the NSPS continue to operate the control equipment in compliance with the regulation. Adequate monitoring, recordkeeping, and reporting are necessary to ensure compliance with the applicable regulations, as required by the Clean Air Act. The information collected from recordkeeping and reporting requirements is also used for targeting in spections, and is of sufficient quality to be used as evidence in court.
**3. Non**
**- duplication, Consultations, and Other Collection Criteria**  The requested recordkeeping and reporting are required under 40 CFR part 60, subpart K

. **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 . I f a state or local agency has adopted its own sim ilar 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, no duplication exists. **3(b) Public Notice Required Prior to ICR Submission to OMB**  An announcement of a public comment period for the renewal of this I CR was published in the Federal Register on Ju ly 8 , 200 9 (7 4 FR 32580 ). No comments were received on the burden published in the Federal Register

. **3(c) Consultations** For this information collection, the previous I CR renewal was used to obtain burden estimates since this I CR renewal was processed under the “Expedited Approach” option provided in May 1, 2008 guidance . Per this guidance, all data and assumptions from the previous I CR renewal were used as the basis for estimating the hourly and cost burdens associated with this renewal. Approximately

220 respondents will be subject to the standard over the three year period covered by

this I CR.
In du stry trade association(s) and other interested parties were provided an opportunity to comment on the burden associated with the standard as it was being developed and the standard has been previously

reviewed to determine the minimum information needed fo r compliance purposes.4

It is our policy

to respond after a thorough review of comments received since the last IC R renewal as well as those submitted in response to the first Federal Register notice. Inthis case, no comments were received. **3(d) Eff ects 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 th at good operation and maintenance practices are applied and emission limitations are met. I f the information required by these standards was collected less frequently , the proper operation and maintenance of control equipment and the possibility

of detect ing 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 T itle 40, chapter 1, part 2, subpart B

- Confidentiality of Business Information (CBI ) (see 40 CFR 2; 41 FR 36902, September 1, 197 6; 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. **4. The Respondents an d the Information Requested**  **4(a) Respondents/NAICS Codes** The respondents to the recordkeeping and reporting requirements are facilities that have storage vessels of petroleum liquids meeting the rule criteria. The Standard Industrial Classification (S IC ) codes and corresponding North American Industry Classification Sy stem (NAI CS) for the respondents are listed below :
**Category SIC Codes**  **NAICS Codes Examples of Regulated**  **Entities** Petroleum and Coal 2911 32411 Petroleum Refinerie s5

**Category SIC Codes**  **NAICS Codes Examples of Regulated**  **Entities** Products Manufacturing 2951 324121 Asphalt Paving Mixture and Block Manufacturing 2952 324122 Asphalt Shingle and Coating Materials Manufacturing 29 9 2 324191 Petroleum Lubricating Oil and Grease Manufacturing 2999 324199 All Other Petroleum and Coal Products Manufactur ing [To compare the SI C and NAI CS codes, see the website at http://www.census.gov/epcd/www/naics.html .] **4(b) Information R**  **equested (i) Data Items** 
Inthis I CR, all the data that is recorded and/ or reported is required by NSPS for Storage Vessels for Petroleum L iquids for Which Construction, Reconstruction or Modification Commenced After June 11, 1973 , and P rior to May 19, 1978 (40 CFR part 60, subpart K) (Renewal)

. A source must make the following reports :
**Notification s**  Construction/reconstruction

. 60.7(a)(1) Phy sical or operational change. 60.7(a)(4) A source must keep the following records : **Recordkeeping** Records are required to be retained for two years. 60.7(f) Owner/Operator shall maintain a record of the petroleum liquid stored, the per iod of storage and the maximum true vapor pressure of that liquid during the respective storage period. 60.113(a)

Maintain records of the occurrence and duration of any startup, shutdown, or malfunction. 60.7(b)6

Electronic Reporting Some of the respo ndents 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 recordkeepin g at a plant site. Also, regulatory

agencies in cooperation with the respondents, continue to create reporting sy stems to transmit data electronically . However, electronic reporting sy stems are still not widely

used. At this time, it is estimated that a pproximately

10 percent of the respondents use electronic reporting.

**(ii) Respondent Activities**

**Respondent Activities** Read instructions. In stall, calibrate, maintain, and operate floating roof or vapor recovery sy stem. Perform an initial performance test, according to manufacturers ’ instructions, and repeat performance tests if necessary

. 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 sy stems for the purpose of collecting, validating, and verifying information. Develop, acquire, install, and utilize technology and sy stems for the purpose of processing and maintaining information. Develop, acquire, install, and utilize technology and sy stems for the purpose of disclosing and providing information. Adjust the existing way s 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. **5. The Information Collected: Agency Activities, Collection Methodology, and Information Management**  **5(a) Agency Activities** EPA conducts the following activities in connection with the acquisitio n, analy sis, storage, and distribution of the required information.7 **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, analy

ze, and maintain data in the AI RS Facility Subs ys tem (AFS). **5(b) Collection Methodology and Management** Following notification of startup, the reviewing authority migh t 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 standard. This information w ill be used to monitor vapor recovery , floating roof or their equivalent pollution control devices, thus ensuring continuous compliance with the standard. Data and records maintained by the respondents are tabulated and published for use in compliance and enforcement programs.
In formation contained in the reports is entered into the AFS which is operated and maintained by

EPA ’ s Office of Compliance. AFS is EPA ’ s database for the collection, maintenance, and retrieval of compliance data for approximately 1 25 ,000 industrial and government

- owned facilities. EPA uses the AFS 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, stor e, retrieve and analy ze the data. The records required by

this regulatio n must be retained by the owner

/operator for two ye ars. **5(c) Small Entity Flexibility** A majority

of the affected facilities are large entities (e.g., large businesses). However, the impact on small entities (e.g., small businesses) was taken into consideration during the development of the regulation. Due to technical considerations involving the process operations and the ty pes of control equipment employed, the recordkeeping and reporting requirements are the same for both small and large entities. The Agency considers these requirements the minimum needed to ensure compliance and, therefore, cannot reduce them further for small entities. **5(d) Collection Schedule** The spec ific frequency

for each information collection activity within this request is shown below in Table 1: Annual Respondent Burden and Cost: NSPS for Standards of Performance for Storage Vessels for Petroleum Liquids for which Construction, Reconstruction o r Modification Commenced after June 11, 1973, and prior to May 19, 1978 (40 CFR part 60, subpart K) (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 I CR. The individual burdens are expressed under standardized headings believed to be consistent with the concept of burden under the Paperwork Reduction Act. Where appropriate, spe cific 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 display s 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 r equirements is estimated to be 7 69 (Total L abor Hours from Table 1). These hours are bas ed on Agency studies and background documents from the development of the regulation, Agency

knowledge and experience with the NSPS program, the previously approved IC R, and any

comments received. **6(b) Estimating Respondent Costs (i) Estimating Labor C**  **osts**
This I CR uses the following labor rates: Managerial $114.49 ($54.52 + 110%) Technical $98.20 ($46.76 + 110%) Clerical $48.53 ($23.11 + 110%) These rates are from the United States Department of Labor, Bureau of Labor Statistics, September 2009, ” 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 standard are labor costs. There are no capital/startup or operation and maint enance costs.

**(iii) Capital/Startup vs. Operation and Maintenance (O&M) Costs** The only ty pe of industry

costs associated with the information collection activity in the regulations are labor costs. There are no capital/startup or operation and maintena nce costs.9

**6(c) Estimating Agency Burden and Cost** The average annual Agency cost during the three years of the I CR is estimated to be $ 22 8

. The only

costs to the Agency

are those costs associated with analy sis of the reported information. EPA ’ s overal l 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. This cost is based on th e average hourly labor rate as follows: Managerial $6 2

. 27 (GS

- 13, Step 5, $38. 92 + 60%) Technical $4 6

. 21 (GS

- 12, Step 1, $28. 88 + 60%) Clerical $2 5

. 01 (GS

- 6, Step 3, $15. 63 + 60%) These rates are from the Office of Personnel Management (OPM) 20 10 Gen eral 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: Annual Burden and Co st for the Federal Government : NSPS for Storage Vessels for Petroleum Liquids for which Construction, Reconstruction or Modification Commenced after June 11, 1973, and p rior to May 19, 1978 (40 CFR p art 60, subpart K) (Renewal). **6(d) Estimating the Res pondent Universe and Total Burden and Costs**  Based on our research for this I CR, on average over the next three years, approximately 220 existing respondents will be subject to the standard. Itis also estimated that no additional sources will become subj ect. The number of respondents is calculated using the following table that addresses the three ye ars covered by

this I CR. **Number of Respondents Respondents That Subm**  **it Reports**  **Respondents That Do Not**  **Submit Any Reports**

**6(e) Bottom Line Burden Hours And Cost Tables**  The bottom line burden hours and cost tables for both the Agency and the respondents appear below. The annual public reporting and recordkeeping burden for this collection of information is estimated to average 3.5 hours per response. **6(f) Reaso ns for Change in Burden**  There is no change in the labor hours or cost to the respondents in this I CR compared to the previous I CR. This is due to two considerations : (1) the regulations have not changed over the past three years and are not anticipated to change over the next three years ; and (2) the growth rate for the respondents is very low, negative , or non - existent. Therefore, the labor hours and cost figures in the previous I CR reflect the current burden to the respondents and are reiterated in th is I CR

. **6(g) Burden Statement** The annual public reporting and recordkeeping burden for this collection of information is estimated to average 3.5 hours per response. Burden means the total time, effort, or financial resources expended by

persons to gen erate, 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 sy stems for the purposes of collecting, validating, and ver ifying information, processing and maintaining information, and disclosing and providing information; adjust the existing way s to comply with any previously

applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information. An agency

may not conduct or sponsor, and a person is not required to respond to, a collection of information unless i t display s a currently valid OMB Control Number. The OMB Control Numbers for EPA ’ s regulations are listed at 40 CFR part 9 and 48 CFR chapter 15.
