**1. Identification of the Information Collection**  **1(a) Title of the Information Collection** Air Emission Standards for Tanks, Surface Impoundment and Containers (40 CFR Part 264, Subpart CC, and 40 CFR Part 265, Subpart CC) (Renewal) , EPA I CR Number 1593.09 , OMB Control Number 2060

- 0318 **1(b ) Short Characterization/Abstract**  The Air Emission Standards for Tanks, Surface Impoundment and Containers were : proposed on July

22, 1991 (56 FR 33490) ; promulgated on December 6, 1994 (59 FR 62896) ; and amended on November 25, 1996 (61 FR 59931) . These regulations apply to existing facilities and new facilities that treat, store, or dispose of hazardous wastes in tanks, surface impoundments, and containers that are subject to subparts I, J, or K of these parts except for sections 264.1, 265.1, and those management units identified at sections 264.1080(b) and 265.1080(b). Also, the requirements of this subpart appl y to large quantity generators that manage hazardous wastes in either tanks or containers [section 262.34(a)(1)(i and ii)] . New facil ities include those that commenced construction or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR part 264 , subpart CC, and 40 CFR part 265, subpart CC

. In general, air emission standards r equire 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 an y startup, shutdown, or malfunction in the operation o f an affected facility , or any period during which the monitoring sy stem is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to the air emission standards

. Any owner/operator subject to the provisions of this part shall maintain a file of these measurements, and retain the file for at least three ye ars following the date of such measurements, maintenance reports, and records. All reports are sent to the d elegated state or local authority . In the event that there is no such delegated authority , the reports are sent directl y to the U

. S

. Environmental Protection Agency (EPA) regional office. Based on our consultations with industry representatives, there is an average of one affected facilities at each plant site and that each plant site has only one respondent (i.e., the owner/operator of the plant site). Over the next three ye ars, an aver age of 6,209 respondents per ye ar will be subject to the standard , and no additional respondents per ye ar will become subject to the standard. This2

includes 70 percent of treatment, storage, and disposal facilities (TSDFs) and 25 percent of large quanti ty generators (LQGs) that are subject to Resource Conservation and Recovery Act (RCRA) subpart CC requirement

. The Office of Management and Budget ( OMB) approved the currentl y active I CR without any

“Terms of Clearance.” All of the TSDFs and LQGs facilities in the United States are owned and operated b y the TSDF and LQG industry

(the “Affected Public”). None of the facilities in the United States are owned b y either state, or local, or tribal government s . They are all privately

- owned , for

- profit businesses. The “burden ” to the Affected Public may be found below in Table 1: Annual Respondent Burden and Cost

– Air Emission Standards for Tanks, Surface Impoundment and Containers (40 CFR Part 264, Subpart CC, and 40 CFR Part 265, Subpart CC) (Renewal) . The Federal Government “burden ” is attributed entirely to work performed by either F ederal employees or government contractors and may be found below in Table 2: Average Annual EPA Burden and Cost

. **2. Need for and Use of the Collection 2(a) Need/Authority for the Collection**  Organic air emissions from hazardous waste TSDFs can contain toxic chemical compounds. Cancer and other adverse non

- cancerous human health effects can result from exposure to these emissions. Also, organic air emissions from TSDFs react photo

- chemically with other compounds in the atmosphere to form ozone. E xcessive ambient ozone concentrations are a major air quality problem in many cities throughout the United States. Nationwide organic air emissions from TSDFs are estimated to be approximately 1 million megagram per year. In 1984, Congress passed the Haz ardous and Solid Waste Amendments (HSWA) to the Resource Conservation and Recovery Act (RCRA) of 1976. Section 3004(n) of HSWA directs the EPA to promulgate regulations for the monitoring and control of air emissions from TSDFs as may be necessary

to prot ect human health and the environment. Recommended standards have been developed b y the EPA under the authority of sections 3002 and 3004 of RCRA to reduce organic air emissions from certain TSDF tanks, surface impoundments, and containers, as well as cert ain hazardous waste generator accumulation tanks. The experience of the EPA in implementing and enforcing New Source Performance Standards (NSPS) and National Emission Standards for Hazardous Air Pollutants (NESHAP) promulgated under authority of the Clean Air Act has demonstrated that certain information must be collected to ensure compliance with air emission standards. Information collection is needed by the EPA for this rulemaking to determine: a) whether a hazardous waste contains sufficientl y low concentrations of volatile organics to allow the wast e to be managed in a tank, surface impoundment, or container without the use of emission controls; and b) for units requiring3

emission controls, whether the controls are being properl y operated and maintained. **2(b) Practical Utility/Users of the Data**
T he recommended standards are applicable to TSDF subject to the existing RCRA subtitle C permitting requirements. The standards require organic emission control equipment to be used on permitted and interim

- status TSDF tanks, surface impoundments, and cont ainers that manage hazardous waste with an average volatile organic concentration at the point of waste generation greater than, or equal to 500 parts per million by weight (ppmw) on a mass

- weighted average basis. In addition, the recommended standards ar e applicable to hazardous waste generators accumulating hazardous wastes in tanks and containers pursuant to conditions specified in 40 CFR part 262.34 (a). These units are exempt from RCRA subtitle C permitting requirements provided the waste generator a ccumulates waste in the unit for no more than 90 day s and complies with the control requirements specified in 40 CFR part 265, subparts I and J. The standards are not applicable to certain waste management units. For example, the requirements of the subp art CC standards do not apply to: 1) a tank, or surface impoundment in which an owner or operator stops adding hazardous waste and begins undergoing closure, or which is closed in accordance with existing RCRA regulations; 2) a container that has a design capacity less than 0.1 cubic meters (26.4 gallons); or 3) a tank, surface impoundment, or container that contains hazardous waste prior to the rule's effective date if no new hazardous waste is added to the unit on, or after the effective date. Each owner or operator of an affected tank, surface impoundment, or container is required b y the recommended standards to comply with the requirements summarized below. i. Standards for Tanks The owner or operator of a tank used to manage hazardous waste with a m ass - weighted average volatile organic content greater than, or equal to 500 ppmw at the point of waste generation is required to install and use emission control equipment. The control equipment requirements are to install, operate, and maintain either a cover connected through a closed

- vent sy stem to a control device, an external floating roof, a fixed roof with an internal floating cover, or a pressure tank that operates with no detectable organic air emissions. An owner or operator is allowed to use a cover without a closed

- vent s ys tem and control device on a tank that satisfies all of the following conditions: 1) the hazardous waste managed in the tank is not mixed, stirred, agitated, or circulated within the tank by the owner or operator using a proce ss that results in splashing, frothing, or visible turbulent flow on the waste surface during normal process operations; 2) no waste fixating, heat

- using (except the minimum heating required to prevent waste freezing, or to maintain adequate waste flow con ditions for continuing normal process operations during cold weather), or heat generating process is conducted in the tank; and 3) either the tank capacity

is less than 75 m 3 (20,000 gallons) and the maximum organic vapor pressure is less than 76.6 kilopas cals (kPa) [11.1 pounds per square inch (psi)], the tank capacity is less than4

151 m 3 (40,000 gallons), and the maximum organic vapor pressure is less than 27.6 kPa (4.0 psi), or the capacit y of the tank is equal to, or greater than 151 m 3 and the maximum organic vapor pressure is less then 5.2 kPa (0.75 psi). ii. Standards for Surface Impoundments. The owner or operator of a surface impoundment used to manage hazardous waste with a mass - weighted average volatile organic content greater than, or equal to 500 ppmw at the point of waste generation is required to install and use emission control equipment. The control equipment requirement is to install, operate, and maintain either a cover, or enclosure connected through a closed

- vent sy stem to a control device. An owner or operator is allowed to use a contact cover (e.g., floating membrane cover) without a closed

- vent s ys tem and control device on a surface impoundment that satisfies all of the following conditions: 1) the hazardous waste managed in the surface impoundment is not mixed, stirred, agitated, or circulated within the surface impoundment by

the owner or operator using a process that results in splashing, frothing, or visible turbulent flow on the waste surface during normal process operations; and 2) no waste fixating, heat treating, or heat

- generating process is conducted in the surface impoundment. iii. Standards for Containers. The owner or operator of a container used to manage hazardous waste with a mass

weighted average volatile organi c content greater than, or equal to 500 ppmw is required to use the following procedures. The owner or operator must place the hazardous waste either into a container equipped with a cover that operates with no detectable organic air emissions when all op enings are secured in a closed, sealed position; or a container having a design capacity less than, or equal to 0.42 m 3 (110 gallons) that complies with all applicable Department of Transportation regulations for packaging hazardous waste for transport und er 49 CFR part 178; or a container that is attached to, or forms a part of any truck, trailer, or railcar, and has been tested for organic vapor tightness within the preceding 12 months in accordance with EPA Method 27. A container is required to be cover ed except when waste is being added, removed, inspected, or sampled, or the container is vented in accordance with good engineering and safety practices for handling flammable, combustible, explosive, or other hazardous materials. A loading operation cond

ucted by pumping into a container having a design capacity greater than, or equal to 0.42 m 3 (110 gallons) must be performed using a conveyance s ystem that uses a tube (e.g., pipe, or hose) to add waste into the container below the waste surface, or within 15.2 cm (6 inches) of the bottom of the container. A container used for waste fixation is required (during the fixation process) to be located in an enclosure with a closed

- vent s ys tem that is operating with sufficient airflow to capture and route all organic vapors vented from the container to a control device. T he enclosure may have permanent or temporary openings, but must be maintained at a pressure below atmospheric pressure such that whenever an open container is placed inside the enclosure, no org anic vapors released from the container exit through the openings.5

iv. Standards for Closed

- Vent Sy stems and Control Devices. The requirements under the recommended subpart CC standards for an individual closed

vent sy stem with control device are identical to those already applicable to TSDF owners, and operators under subpart AA in 40 CFR parts 264 and 265. The subpart AA standards were promulgated in June 1990, and require TSDF owners and operators to use closed

- vent s ys tems and control devices to control organic air emissions from process vents associated with distillation, fractionation, thin

- film evaporation, solvent extraction, and air, or steam stripping operations at a TSDF. v. Waste Determinations. If an owner or operator chooses to det ermine that a particular tank, surface impoundment, or container is not subject to specific control requirements on the basis of the volatile organic concentration at the point of waste generation, or organic vapor pressure of the hazardous waste being man aged in the unit, the owner or operator is required to perform periodic waste determinations. Either direct measurement or evaluation of the waste is used to determine that a waste contains a mass

- weighted average concentration at the point of waste gener ation of less than 500 ppmw volatile organics, or is below the organic vapor pressure limit. Direct measurement of the waste volatile organic concentration or organic liquid vapor pressure is performed using EPA reference test methods. An evaluation of the waste must demonstrate conclusively that the waste volatile organic concentration or organic vapor pressure is below the specified limit under all conditions. For example, a company that generates a hazardous waste as a result of manufacturing a produc t could provide the EPA with evidence that no volatile organic chemicals are used in the manufacturing process. The waste determination for a waste generated as a continuous flow needs to be performed initiall y before the first time an y portion of the haz ardous waste is placed in a unit subject to the final standards and repeated at least annually . In addition, the owner or operator is required to perform a new waste determination whenever changes to the process generating, or treating the hazardous waste could potentially cause the average volatile organic concentration to increase to, or above 500 ppmw, or cause the treatment process performance to decline below the minimum efficiency

requirements specified in the rule. For a hazardous waste that is gen erated as a discrete quantity

of material from a batch process, sequenced, or intermittent operation, or non - continuous source, the waste determination must be performed for each discrete quantity of hazardous waste generated before the waste is placed in a waste management unit not controlled for organic air emissions. vi. Monitoring and Inspection Requirements. To ensure that emission control equipment is properly operated and maintained, the recommended standards require the owner or operator to inclu de certain emission control equipment items as part of the inspections the owner or operator already is conducting to comply with existing RCRA standards (e.g., 40 CFR 264.195 for tanks, 40 CFR 264.254 for surface6

impoundments, 40 CFR 264.174 for container s). During the visual inspections, emission control equipment covers on tanks are to be checked semiannually by the facilit y workers to ensure that equipment is being used properl y (i.e., covers are closed and latched except when an opening must be used i n accordance with conditions specified in the rules) and that the equipment is being maintained in good condition (e.g., no visible holes, gaps, tears, or splits have developed in covers). Continuous monitoring of control device operation is required unde r the rules. This involves the use of automated instrumentation to measure critical operating parameters that indicate whether the control device is operating correctl y or is malfunctioning. Semiannual leak detection monitoring using EPA Reference Method 21 also is required for certain cover components to ensure gaskets and seals are in good condition, and for closed

- vent sy stems to ensure all fittings remain leak

- tight. In addition, each closed

- vent s ys tem must be monitored for leaks using Reference Method 21 at least once per year. vii. Recordkeeping Requirements. To provide the EPA enforcement personnel with a means of verifying compliance with the recommended standards, the owner or operator is required to record certain information documenting emi ssion control equipment performance and maintenance in the on

- site facilit y operating logs or files. This information will be available for review b y the EPA enforcement personnel during on

- site compliance inspection. The information to be collected and recorded includes: the results of all waste determinations such as of volatile organic concentration at the point of generation and organic vapor pressure; waste determination documentation for units not using air emission controls in accordance with the r ule control requirements; design specifications for closed

- vent sy stems and control equipment inspection and control equipment; emission control equipment inspection and monitoring results; Reference Method 27 test results; control device exceedances and a ctions taken to remedy them; leak repairs; management of carbon removed from carbon adsorption sy stems, and identification of equipment fittings designated as difficult, or unsafe to monitor, or inspect. Consistent with 40 CFR sections 264.73 and 265.73, the recommended standards require that all records be maintained in the facility operating record until facility closure except records and results of inspections and monitoring, which need to be kept for at least three ye ars from the date of entry

. viii. Reporting Requirements. The recommended reporting requirements for the owner or operator of a TSDF are simple and straightforward. There are no reporting requirements for the owner or operator of an interim status TSDF. The owner or operator of a perm itted TSDF is not required to submit any reports unless: 1) a control device malfunction is not corrected within 24 hours of detection; or 2) a hazardous waste with organic content at the point of waste generation that equals, or exceeds, the 500 ppmw mass - weighted average volatile organic concentration, or that has been treated b y a process that fails to meet applicable general requirements in the recommended rule,7

is managed in a unit without proper emission controls. If an y of these events (referr ed to as “exceedances”) occur, the owner or operator is required to maintain a record of the exceedance. For control device exceedance, the owner or operator is required to submit a written report to the EPA on a semiannual basis describing an y exceedance s that occurred during the past 6

- month period, explain why

each exceedance occurred, and what action was taken to return to compliance. For waste exceedances, the owner or operator is required to submit a written report to the EPA within 15 calendar day s of the time that the owner or operator becomes aware of the circumstances explaining why the hazardous waste was not managed in accordance with the requirements of the standards. For some TSDF tanks, an owner or operator is allowed to use either a fixed roof with an internal floating cover, or an external floating roof as an alternative to a cover vented to a control device. Reporting requirements for internal and external floating roofs require the owner or operator to notify

the EPA at least 30 day s prior to the filling of the empty tank to provide the EPA the opportunity

to inspect the roof and seals for compliance with the standards prior to refilling. This requirement is necessary because the internal or external roof seals can only be inspected whe n the tank is empty . Inspection is required initially and no more than once every five years for external floating roofs and 10 years for internal floating roofs. The collected information will be used by the EPA enforcement personnel to ensure that the requirements of the recommended rules are being properl y applied and that emission control devices are being properly operated and maintained on a continuous basis. In addition, records and reports are necessary to enable the EPA to identify TSDF owners o r operators that may not be operating in compliance with the standards. The reported information is used by the EPA to target TSDFs for inspection and identify what records, or waste management units should be inspected at the TSDF. The information that TSDF owners or operators are required to maintain is recorded in sufficient detail to enable owners or operators to demonstrate their means of complying with the applicable standards. The data collected b y the affected facility is retained at the facility for a minimum of three years. In addition, the information collected from the recordkeeping and reporting requirements 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 264, subpart CC, and 40 CFR part 265, s ubpart CC

. **3(a) Non**
**- duplication**  If the subject standards have not been delegated, the information is sent directl y to the appropriate EPA re gional office. Otherwise, the information is sent directl y 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 cop y of the report submitted to the state or local a gency can be sent to the Administrator in lieu of the report required by the Federal standards. Therefore, duplication does not exist.8

**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 (78 FR 33409) on June 4, 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 b y industry , in compliance with the recordkeeping and reporting provisions in the standard, is the Online Tracking Information System (OTI S) which is operated and maintained by EPA's Office of Compliance. OTIS is EPA’s database for the collection, maintenance, and retrieval of all complianc e data. The respondent universe estimate is based on information from the RCRA Info database. Industry trade associations and other interested parties were provided an opportunity to comment on the burden associated with the standard as it was being dev eloped and the standard has been previously

reviewed to determine the minimum information needed for compliance purposes. In developing this I CR, we contacted : 1) the American Chemistry Council (ACC) , at (703) 741

- 6050 ; and 2) the Sy nthetic Organic Chemical Manufacturing Association (SOCMA) , at (202) 721

- 4100. 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 recordkeepi ng 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 frequentl y, the proper operation and maintenance of control eq uipment and the possibility

of detecting violations would be less likely

. **3(e) General Guidelines**
T hese reporting or recordkeeping requirements do not violate any of the regulations promulgated b y 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 2,9

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**

Electronic Reporting Some of the r espondents 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 th e respondents continue to create reporting sy stems to transmit data electronically . However, electronic reporting s ys tems are still not widely used. At this time, it is estimated that approximately zero percent of the respon dents use electronic reporting.22 **(ii) Respondent Activities**

**Respondent Activities** Read instructions. Install, calibrate, maintain, and operate CMS for opacity , or for pressure drop and liquid supply pressure for floating roof or vapor recovery sy stem

. Perform initial performance test, 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 in formation. 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. 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 s ys tem. 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 :23 **Agency Activities** Review notifications and reports, including performance test reports, and excess emissions reports, required to be submitted by industry

. Audit facility

records. Input, anal yz e, and maintain data in the Online Tracking Information Sy stem ( OTI S )

. **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 p roperl y installed and operated. Performance test reports are used b y the Agency to discern a source ’ s initial capability to comp ly with the emission standard, and note the operating conditions under wh ich compliance was achieved. Data and records maintained by the respondents are tabulated and published for use in compliance and enforcement programs. The semiannual reports are used for problem identification, as a check on source operation and mainten ance, and for compliance determinations.
In formation contained in the reports is entered into OTI S which is operated and maintained by

EPA's Office of Compliance. OT IS is EPA ’ s database for the collection, maintenance, and retrieval of compliance data fo r approximately 125,000 industrial and government

- owned facilities. EPA uses the OTI S for tracking air pollution compliance and enforcement b y local and state regulatory agencies, EPA regional offices and EPA headquarters. EPA and its delegated Authoriti es can edit, store, retrieve and analyze the data. The records required b y this regulation must be retained by the owner/operator for three ye ars. **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 ty pes 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 require ments 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 sp ecific frequency

for each information collection activity within this request is shown in below Table 1: Annual Respondent Burden and Cost

– Air Emission Standards for24

Tanks, Surface Impoundment and Containers (40 CFR Part 264, Subpart CC, and 40 CFR Part 265, Subpart CC) (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 IC R. The individual burdens are expressed under standardized headings believed to be consistent with the concept of burden under the Paperwork Reduction Act. Where ver 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 ave rage annual burden to industry over the next three years from these recordkeeping and reporting requirement s is estimated to be 712,293 hours ( Total Labor Hours from Table 1 below ). T hese hours are based on Agency studies and background documents from th e development of the regulation, Agency knowledge and experience with the RCRA program, the previously

approved IC R, and any

comments received. **6(b) Estimating Respondent Costs (i) Estimating Labor Costs**  This I CR uses the following labor rates: Managerial $ 123.04 ($5 8

Civilian Workers, by occupational and indu stry group. ” The rates are from column 1, “ Total compensation. ” The rates have been increased b y 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 ty pe of industry

costs associated with the information collection activities in the subject standards are both labor costs which are addressed elsewhere in this I CR and the costs associated with continuous monitoring. The capital/st artup costs are an initial, one - time cost when a facility

becomes subject to the regulation. The annual operation and maintenance costs are the ongoing costs to maintain the monitor and other costs such as photocopying and postage.25 **(iii) Capital/Startup vs. Operation and Maintenance (O&M) Costs**

. **6(c) Estimating Agency Burden and Cost** The only costs to the Agency

are those costs associated with anal ys is of the reported information. EPA's ove rall compliance and enforcement program i ncludes activities such as the examination of records maint ained 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 $ 338,310

. This cost is based on the average hourl y labor rate as follows: Managerial $ 6 2.27 (GS

**6(d) Estimating the Respondent Universe and Total Burden and Costs** Based on our research for this I CR, on average over the next three ye ars, approximately 6,209 existing respondents will be subject to the standard. It is estimated that no new respondent s per ye ar will become subject. The overall average number of respondents, as shown in the table below, is 6,209 per year. The respondent universe was estimated during rule development ba sed on the information that 70 percent of TSDFs and 25 percent of LQGs would be subject to RCRA subpart CC requirements. The regulated universe is the sum of applicable TSDFs and LQGs: Regulated Universe 70% of 2,393 = 1,675 (TSDFs subject to RCRA subpart CC) 25% of 18,135 = 4,534 (LQGs subject to RCRA subpart CC) 1,675 + 4,534 = 6,209 respondents subject to RCRA subpart CC. Semiannual Reporting It is assumed that 0.5 percent of control devices malfunction resulting in the need for a semiannua l report. The Sistersville Plant XLproject alway s reports semiannually

.

0.5% of 6,209 = 31 31 + Sistersville Plant = 32 (Semiannual Reports) Other Reports For exceedances it is assumed that 1 percent of waste determination results in exceedance annu ally . This would result in the need for a report to EPA within 15 calendar day s. Therefore, 1 percent of the regulated universe would submit a report to EPA within 15 calendar day s, once per year. 1% of 6,209 = 62 (Report to EPA within 15 calendar day s, once per year) We also assume that the Sisterville Plant XLproject will submit an annual report. Notification Reports It is assumed that 10 percent of sources with internal floating roofs and 20 percent of sources with external floating roofs will require notifications annually . One facilit y notifies EPA that they will use the hydrogen peroxide management exemption (40 CFR 264.1080(d) and 40 CFR 265.1080(d).

10% of 6,209 = 620.927 20% of 6,209 = 1,241.8 1,2 41.8 + 620.9 = Facility using hydrogen peroxide exemption = 1,864 (Notification Reports) 1,864 + 62 + 32 = 1,958 (Number of existing respondents that submit reports) The number of respondents is calculated using the following table that addresses the three ye ars covered b y this ICR.

. **6(f) Reasons for Change in Burden** There is an adjustment increase in the respondent burden hours and costs from the most recentl y approved ICR. The previous ICR used rounded numbers, while this I CR uses exact values in calculating burden hours. In addition, this I CR uses updated labor rates from the Bureau of Labor St atistics to calculate burden costs. There is also an increase of one response in this ICR due to a correction. The previous ICR did not account for the annual project report for the Sisterville Plant when calculating the total number of responses. **6( g) Burden Statement**  The annual public reporting and recordkeeping burden for this collection of information is estimated to average 114 hours per response. Burden means the total time, effort, or financial resources expended b y 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 s ys tems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing way s to compl y 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 it displays a valid OMB Control Number. The OMB Control Numbers for EPA regulations are listed at 40 CFR part 9 and 48 CFR chapter 15. To comment on the Agency's need for this information, the accuracy of the provided burden estimates, and any suggested me thods for minimizing respondent burden, including the use of automated collection techniques, EPA has established a public docket for this I CR under Docket ID Number EPA

**Assu mptions:**  a We have assumed that the average number of respondents that will be subject to this rule will be 6,209. There will be no new additional sources during the next three years of this ICR. b This ICR uses the following labor rates: $123.04 per hour for Executive, Administrative, and Managerial labor; $101.22 per h our for Technical labor, and $51.18 per hour for Clerical labor. These rates are from the United States Department of Labor, Bur eau 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 perc ent to account for the benefit packages available to those emplo yed by private industry.
c We have assumed that all of the respondents will read the rule and instructions. d We have assumed that only the Sistersville, WV Plant XL Project will be reporting.36

e We have assumed that 0.5 percent of respondents will report control devices malfunction, resulting in exceedance annually (0.5% x 6,209=31), along with the Sistersville Plant XL project (1) always reports semiannually for a total of 31+1=32 semiannual reports. f We have assumed that 1 percent of waste determination will result in exceedance annually (1% x 6,209=62). g We have assumed that only one facility currently uses the exemption regarding hydrogen peroxide management located at 40 CFR 264.1080(d) and 40 CFR 265.1080(d). h We have assumed that 20 percent of the tank roofs will be inspected each year (external roof). i We have assumed that 10 percent of respondents will empty and refill a tank (internal floating roof). j We assume recordkeeping only for the Sistersville, WV Plant XL Project. k We have assumed that it will take each respondent sixteen hours once per year to plan activities. l We have assumed that it will take 50 percent of respondent will be required on a daily basis to inspect and monitor each clos ed vent system.
m We have assumed that 20 percent of respondents will take 4 hours once every five years to complete the primary seal inspection.
n We have assumed that 20 percent of tanks with alternative emission controls (floating roofs) will each take 4 hours 0.2 times per year, which equates to once every 5 years, to complete the primary seal inspection.

**Assu mptions:**  a We have assumed that the average number of respondents that will be subject to this rule will be 6,209. There will be no new additional sources during the next three years of this ICR. b This cost is based on the following labor rates w hich incorporates a 1.6 benefits multiplication factor to account for government overhead expenses: $62.27 for Managerial (GS

- 13, Step 5, $38.92 x 1.6), $46.21 for Technical (GS

- 12, Step 1, $28.88 x 1.6), and $25.01 for Clerical (GS

- 6, Step 3, $15.63 x 1.6). These rates are from the Office of Personnel Management (OPM) 2013 General Schedule which excludes locality rates of pay. c Annual responses assume 1 percent of waste determination results in an excee dance (1% of 6,209 potential respondents). d Semiannual responses assumes 0.5% of control devices malfunction resulting in an exceedance (0.5% of 6,209 potential responde nts), plus the Sistersville, WV Plant.
e We have assumed that 10 percent of interna l floating roof respondents (10% x 6,209 = 621), plus 20% of external roof respondents (20% x 6,209 = 1,242), and one facility using hydrogen peroxide exemption (621 + 1,242 + 1 = 1,864) will submit notification reports. f We have assumed that it will take respondents 8 hours once per year to review selected site and review permit records.
