ENVIRONMENTAL PROTECTION AGENCY

NSPS for Nitric Acid Plants for which Construction, Reconstruction or Modification Commenced after October 14, 2011 (40 CFR Part 60, Subpart Ga) (Renewal)

1. Identification of the Information Collection

1(a) Title of the Information Collection

NSPS for Nitric Acid Plants for which Construction, Reconstruction or Modification Commenced after October 14, 2011 (40 CFR Part 60, Subpart Ga) (Renewal), EPA ICR Number 2445.04, OMB Control Number 2060-0674.

1(b) Short Characterization/Abstract

The New Source Performance Standards (NSPS) for Nitric Acid Plants for which Construction, Reconstruction or Modification Commenced after October 14, 2011 (40 CFR Part 60 Subpart Ga) were proposed on October 14, 2011, and promulgated on August 14, 2012. These regulations apply to new nitric acid production units (NAPUs) that produce weak nitric acid by either the pressure or atmospheric pressure process. Nitrogen oxide (NO_X) is the pollutant regulated under this subpart. The standards limit nitrogen oxides, expressed as nitrogen dioxide (NO₂), to 0.50 lb per ton of 100 percent nitric acid produced. This information is being collected to assure compliance with 40 CFR Part 60, Subpart Ga.

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

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

The “Affected Public” includes owners or operators of nitric acid production units constructed, modified, or reconstructed after October 14, 2011. The ‘burden’ to the Affected Public may be found below in Table 1: Annual Respondent Burden and Cost – NSPS for Nitric Acid Plants for which Construction, Reconstruction or Modification Commenced after October 14, 2011 (40 CFR Part 60, Subpart Ga) (Renewal). The ‘burden’ to the “Federal Government” is attributed entirely to work performed by either Federal employees or government contractors and may be found below in Table 2: Average Annual EPA Burden and Cost – NSPS for Nitric Acid Plants for which Construction, Reconstruction or Modification Commenced after October 14, 2011 (40 CFR Part 60, Subpart Ga) (Renewal).

Over the next three years, we estimate that approximately 9.6 units per year, which are owned and operated by the nitric acid production industry, will be subject to these standards. This includes 8.4 existing units per year, with an additional 1.2 additional units per year that will become subject to these same standards. Plants can have more than one nitric acid production unit onsite. None of the nitric acid plants in the United States are owned by either state, local, tribal or the Federal government. They are all owned and operated by privately-owned, for-profit businesses. We assume that they will all respond to EPA inquiries.

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

2. Need for and Use of the Collection

2(a) Need/Authority for the Collection

The EPA is charged under Section 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 system of continuous emissions reduction which (taking into consideration the cost of achieving such emissions reduction, or any non-air quality health and environmental impact and energy requirements) the Administrator 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 standards every eight years.

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, NOx emissions from nitric acid plants either cause or contribute to air pollution that may reasonably be anticipated to endanger public health and/or welfare. Therefore, the NSPS were promulgated for this source category at 40 CFR Part 60, Subpart Ga.

2(b) Practical Utility/Users of the Data

The recordkeeping and reporting requirements in these 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 these same standards at all times.

The notifications required in these standards are used to inform the Agency or delegated authority when a source becomes subject to the requirements of the regulations. The reviewing authority may then inspect the source to check if the pollution control devices are properly installed and operated, leaks are being detected and repaired, and that these standards are being met. The performance test may also be observed.

The required noncompliance and malfunction 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 60, Subpart Ga.

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 (83 FR 24785) on May 30, 2018. One comment was received on the burden published in the Federal Register for this renewal; however, the commenter only indicated opposition to any new regulations or rule changes and did not provide any follow-up information. We note that there are no rule changes addressed in this renewal.

3(c) Consultations

The Agency has consulted industry experts and internal data sources to project the number of affected facilities and industry growth over the next three years. The primary source of information as reported by industry, in compliance with the recordkeeping and reporting provisions in these standards, is the Integrated Compliance Information System (ICIS). ICIS is EPA’s database for the collection, maintenance, and retrieval of compliance data for industrial and government-owned facilities. The growth rate for the industry is based on our consultations with the Agency’s internal industry experts. Approximately 8.4 units per year, which are owned and operated by the nitric acid production industry, will be subject to these standards over the three-year period covered by this ICR, and an additional 1.2 additional units per year will become subject to these same standards.

Industry trade association(s) and other interested parties were provided an opportunity to comment on the ‘burden’ associated with these standards as it was being developed and these same standards have been reviewed previously to determine the minimum information needed for compliance purposes. In developing this ICR, we contacted both The Fertilizer Institute, at 202-962-0490, and the American Chemistry Council, at (703) 741-5000. The Fertilizer Institute provided a list of operating, planned, or under construction nitric acid plants and related capacity data for years 2013 through 2020; the data provided did not definitively identify the nitric acid plants that are subject to 40 CFR 63, Subpart Ga, but it suggested that the prior growth rate for the industry of 1.2 units per year remained reasonable.

It is our policy to respond after a thorough review of comments received since the last ICR renewal, as well as for those submitted in response to the first Federal Register notice. The comments received and our responses may be found in Section 3(b) above and the docket for this ICR at http://www.fdms.gov.

3(d) Effects of Less-Frequent Collection

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

3(e) General Guidelines

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

3(f) Confidentiality

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

3(g) Sensitive Questions

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

4. The Respondents and the Information Requested

4(a) Respondents/SIC Codes

The respondents to the recordkeeping and reporting requirements are nitric acid plants. The United States Standard Industrial Classification (SIC) code for the respondents affected by the standards is SIC 2873 which corresponds to the North American Industry Classification System (NAICS) code 32311 for Nitrogenous Fertilizer Materials Manufacturing.

4(b) Information Requested

(i) Data Items

In this ICR, all the data that are recorded or reported is required by the NSPS for Nitric Acid Plants for which Construction, Reconstruction or Modification Commenced after October 14, 2011 (40 CFR Part 60, Subpart Ga).

Electronic Reporting

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

(ii) Respondent Activities

Respondent Activities

Familiarization with the regulatory requirements.

Install, calibrate, maintain, and operate Continuous Emissions Rate Monitoring Systems (CERMS), which include NO_X concentration and gas flow rate monitors.

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 processing and maintaining information.

Develop, acquire, install, and utilize technology and systems for disclosing and providing information.

Train personnel to be able to respond to a collection of information.

Train personnel on CERMS operation and maintenance.

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 acquisition, analysis, storage, and distribution of the required information.

Agency Activities

Review notifications and reports, including performance test reports, and excess emissions reports, required to be submitted by industry.

Audit facility records.

Input, analyze, and maintain data in the Enforcement and Compliance History Online (ECHO) and ICIS.

5(b) Collection Methodology and Management

Following notification of startup, the reviewing authority could inspect the source to determine whether the pollution control devices are properly installed and operated. Performance test reports are used by the Agency to discern a source’s initial capability to comply with the emission standard. Data and records maintained by the respondents are tabulated and published for use in compliance and enforcement programs. The reports of noncompliance are used for problem identification, as a check on source operation and maintenance, and for compliance determinations.

Information contained in the reports is reported by state and local governments in the ICIS Air database, which is operated and maintained by EPA's Office of Compliance. ICIS is EPA’s database for the collection, maintenance, and retrieval of compliance data for industrial and government-owned facilities. EPA uses ICIS 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 this regulation must be retained by the owner/operator for two years.

5(c) Small Entity Flexibility

Most, if not all, of the anticipated new sources will be large entities (e.g., 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 – NSPS for Nitric Acid Plants for which Construction, Reconstruction or Modification Commenced after October 14, 2011 (40 CFR Part 60, Subpart Ga) (Renewal).

6. Estimating the Burden and Cost of the Collection

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

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

6(a) Estimating Respondent Burden

The average annual burden to industry over the next three years from these record-keeping and reporting requirements is estimated to be 1,740 hours (Total Labor Hours from Table 1 below). These hours are based on Agency studies and background documents from the development of the regulation, Agency knowledge and experience with the NSPS 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 $147.40 ($70.19+ 110%)

Technical $117.92 ($56.15 + 110%)

Clerical $57.02 ($27.15 + 110%)

These rates are from the United States Department of Labor, Bureau of Labor Statistics, June 2018, “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 type of industry costs associated with the information collection activities in the subject standard(s) are both labor costs which are addressed elsewhere in this ICR and the costs associated with continuous monitoring. The capital/startup costs are one-time costs when a facility becomes subject to these regulations. The annual operation and maintenance costs are the ongoing costs to maintain the monitor and other costs such as photocopying and postage.

(iii) Capital/Startup vs. Operation and Maintenance (O&M) Costs

Capital/Startup vs. Operation and Maintenance (O&M) Costs
(A) Continuous Monitoring Device	(B) Capital/Startup Cost for One Respondent	(C) Number of New Respondents	(D) Total Capital/Startup Cost, (B X C)	(E) Annual O&M Costs for One Respondent	(F) Number of Respondents with O&M	(G) Total O&M, (E X F)
NOx CERMS and flow meter	$136,174	1.2	$163,409	$9,787	9.6	$93,955
Initial CERMS testing	$15,019	1.2	$18,023
Initial flow meter testing	$6,229	1.2	$7,475
File cabinet 1				$43	9.6	$413
TOTAL (Rounded) 2			$189,000			$94,400

¹ Included as O&M because the cost is annualized using a 7 percent interest rate and a 15-year life (i.e., CRF of 0.1098).

² Totals have been rounded to 3 significant digits. Figures may not add exactly due to rounding.

The total capital/startup costs for this ICR are $189,000. This is the total of column D in the above table.

The total operation and maintenance (O&M) costs for this ICR are $94,400. This is the total of column G.

The average annual cost for capital/startup and operation and maintenance costs to industry over the next three years of the ICR is estimated to be $283,000. These are the recordkeeping costs.

6(c) Estimating Agency Burden and Cost

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

The average annual Agency cost during the three years of the ICR is estimated to be $2,870.

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

Managerial $65.71 (GS-13, Step 5, $41.07 + 60%)

Technical $48.75 (GS-12, Step 1, $30.47 + 60%)

Clerical $26.38 (GS-6, Step 3, $16.49 + 60%)

These rates are from the Office of Personnel Management (OPM), 2018 General Schedule, which excludes locality rates of pay. The rates have been increased by 60 percent to account for the benefit packages available to Federal government employees. Details upon which this estimate is based appear below in Table 2: Average Annual EPA Burden and Cost – NSPS for Nitric Acid Plants for which Construction, Reconstruction or Modification Commenced after October 14, 2011 (40 CFR Part 60, Subpart Ga) (Renewal).

6(d) Estimating the Respondent Universe and Total Burden and Costs

Based on our research for this ICR, on average over the next three years, approximately 8.4 existing respondents will be subject to these standards. It is estimated that an additional 1.2 respondents per year will become subject to these same standards. The overall average number of respondents, as shown in the table below, is 9.6 per year.

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

Number of Respondents
	Respondents That Submit Reports		Respondents That Do Not Submit Any Reports
Year	(A) Number of New Respondents 1	(B) Number of Existing Respondents	(C) Number of Existing Respondents that keep records but do not submit reports	(D) Number of Existing Respondents That Are Also New Respondents	(E) Number of Respondents (E=A+B+C-D)
1	1.2	7.2	0	0	8.4
2	1.2	8.4	0	0	9.6
3	1.2	9.6	0	0	10.8
Average	1.2	8.4	0	0	9.6

¹ New respondents include sources with constructed, reconstructed and modified affected facilities.

Column D is subtracted to avoid double-counting respondents. As shown above, the average Number of Respondents over the three-year period of this ICR is 9.6.

The total number of annual responses per year is calculated using the following table:

Total Annual Responses
(A) Information Collection Activity	(B) Number of Respondents	(C) Number of Responses	(D) Number of Existing Respondents That Keep Records But Do Not Submit Reports	(E) Total Annual Responses E=(BxC)+D
Notification of construction / reconstruction	1.2	1	0	1.2
Notification of actual startup	1.2	1	0	1.2
Notification of physical or operational change	1.2	1	0	1.2
Notification of CERMS demonstration	1.2	1	0	1.2
Notification of initial performance test	1.2	1	0	1.2
Report of performance test	1.2	1	0	1.2
NOx noncompliance report	0.96	1	0	0.96
Report of malfunctions	0.96	1	0	0.96
			Total (rounded)	9

The number of Total Annual Responses is 9.

The total annual labor costs are $198,000. Details regarding these estimates may be found below in Table 1: Annual Respondent Burden and Cost – NSPS for Nitric Acid Plants for which Construction, Reconstruction or Modification Commenced after October 14, 2011 (40 CFR Part 60, Subpart Ga) (Renewal).

6(e) Bottom Line Burden Hours and Cost Tables

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

(i) Respondent Tally

The total annual labor hours are 1,740 (rounded). Details regarding these estimates may be found below in Table 1. Annual Respondent Burden and Cost – NSPS for Nitric Acid Plants for which Construction, Reconstruction or Modification Commenced after October 14, 2011 (40 CFR Part 60, Subpart Ga) (Renewal).

We assume that burdens for managerial tasks take 5% of the time required for technical tasks because the typical tasks for managers are to review and approve reports. Clerical burdens are assumed to take 10% of the time required for technical tasks because the typical duties of clerical staff are to proofread the reports, make copies and maintain records.

Furthermore, the annual public reporting and recordkeeping burden for this collection of information is estimated to average 193 hours per response.

The total annual capital/startup and O&M costs to the regulated entity are $283,000. The cost calculations are detailed in Section 6(b)(iii), Capital/Startup vs. Operation and Maintenance (O&M) Costs.

(ii) The Agency Tally

The average annual Agency burden and cost over next three years is estimated to be 60 labor hours at a cost of $2,870; see below in Table 2: Average Annual EPA Burden and Cost – NSPS for Nitric Acid Plants for which Construction, Reconstruction or Modification Commenced after October 14, 2011 (40 CFR Part 60, Subpart Ga) (Renewal).

We assume that burdens for managerial tasks take 5% of the time required for technical tasks because the typical tasks for managers are to review and approve reports. Clerical burdens are assumed to take 10% of the time required for technical tasks because the typical duties of clerical staff are to proofread the reports, make copies and maintain records.

6(f) Reasons for Change in Burden

The increase in ‘burden’ from the most recently-approved ICR is due to an adjustment. The adjustment increase in burden is due to an increase in the number of new or modified sources. The change in burden for the new and existing facilities is due primarily to updated estimates of existing and anticipated new sources based on information from industry, which supports a constant growth rate. There is an increase in the number of total annual responses. This increase is due to the update in the number of respondents, as well as a correction to the prior burden estimates, which did not account for submittal of reports for malfunctions (40 CFR 60.77a(f)). Finally, there is a small adjustment increase in the capital/startup vs. operation and maintenance (O&M) costs as calculated in section 6(b)(iii) compared with the costs in the previous ICR. The increase in O&M costs reflected in this ICR is due to the increased universe of respondents.

6(g) Burden Statement

The annual public reporting and recordkeeping burden for this collection of information is estimated to average 193 hours per response. ‘Burden’ means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information either to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously-applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information.

An agency may neither conduct nor 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 methods for minimizing respondent burden, including the use of automated collection techniques, EPA has established a public docket for this ICR under Docket ID Number EPA-HQ-OECA-2014-0103.

a We have assumed approximately 8.4 existing respondents are subject to the standard. It is estimated that an additional 1.2 respondents per year will become subject to the standard. The overall average number of respondents is 9.6 per year over the three-year period of this ICR.
b This ICR uses the following labor rates: $147.40 (Managerial), $117.92 (Technical), and $57.02 (Clerical). These rates are from the United States Department of Labor, Bureau of Labor Statistics, June 2018, “Table 2. Civilian Workers, by occupational and industry group", 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 approximately 10% of all respondents will submit NOx non-compliance reports or reports of malfunctions.
d Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.
