SUPPORTING STATEMENT

ENVIRONMENTAL PROTECTION AGENCY

Standards of Performance for Nitric Acid Plants for Which Construction, Reconstruction, 

or Modification Commenced After September 30, 2011 

(40 CFR part 60, subpart Ga)

August 2011

Part A of the Supporting Statement

1. Identification of the Information Collection

(a) Title and Number of the Information Collection.

“Recordkeeping and Reporting Requirements for Nitric Acid Plants for Which 

Construction, Reconstruction, or Modification Commenced After September 30, 2011 (40 CFR 

Part 60, Subpart Ga).” The EPA ICR tracking number is 2445.01.

(b) Short Characterization.

The New Source Performance Standards (NSPS) for nitric acid plants (40 CFR part 60, 

subpart G) were proposed on August 17, 1971, and promulgated on June 14, 1974. This 

information collection is for a new subpart Ga, which will apply to nitric acid production units 

which commence construction, modification, or reconstruction after the date of proposal. 

Nitrogen oxide (NOX) is the pollutant regulated under this subpart. The standards limit nitrogen 

oxides, expressed as nitrogen dioxide (NO2), in excess of 0.50 lb per ton of 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. Owners or operators 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 sources subject to NSPS. 

Any owner or 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 United 

States Environmental Protection Agency (EPA) regional office.

Potential respondents are owners or operators of new nitric acid production units. It is 

estimated that an additional 4 newly constructed nitric acid production units will become subject 

to the regulation in the next three years. Plants can have more than one nitric acid production unit

onsite.

2. Need for and Use of the Collection

(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 system of emission reduction which 

(taking into account the cost of achieving such reduction and 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 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 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 cause or 

contribute to air pollution that may reasonably be anticipated to endanger public health or 

welfare. Therefore, the NSPS will be promulgated for this source category at 40 CFR part 60,

subpart Ga.

(b) Use/Users of the Data.

The control of emissions of NOX from nitric acid plants not only requires the installation 

of properly designed equipment, but also the operation and maintenance of that equipment. 

Emissions of NOX from nitric acid plants are the result of operation of the affected plants. 

The standards are achieved by the reduction of pollutant emissions using control 

technology. The notifications required in the applicable regulations are used to inform the 

Agency or delegated authority when a source becomes subject to the requirements of the 
3

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.

For our analysis of these standards, we assume sources will rely on the reduction of NOX

by using Selective Catalytic Reduction (SCR). The required notifications are used to inform the 

Agency or delegated authority when a source becomes subject to the standard. The reviewing 

authority may then inspect the source to check if the pollution control devices are properly 

installed and operated and the standard is being met. Performance test reports are needed as these 

are the Agency’s record of a source’s initial capability to comply with the emission standard, and 

note the operating conditions under which compliance was achieved. The periodic reports are 

used for problem identification, as a check on source operation and maintenance, and for 

compliance determinations. The information generated by the monitoring, recordkeeping, and 

reporting requirements described in this ICR is used by the Agency to ensure that plants affected 

by the NSPS continue to operate the control equipment used to achieve compliance with the 

NSPS. Adequate monitoring, recordkeeping, and reporting are necessary to ensure compliance 

with these standards, as required by the Clean Air Act. The information collected from 

recordkeeping and reporting requirements is also used for targeting inspections, and is of 

sufficient quality to be used as evidence in court. 

3. Nonduplication, Consultations, and Other Collection Criteria

(a) Nonduplication.

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 their 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, no 

duplication exists.

(b) Public Notice Required Prior to ICR Submission to OMB.

This section is not applicable because this is a rule related ICR.

(c) Consultations.

During development of the proposed revisions, EPA held meetings and conference calls 

with representatives of The Fertilizer Institute (TFI). We estimate that approximately 4 nitric 

acid production units will be constructed, modified, or reconstructed, or expanded over the next 

3 years.

(d) Effects of Less Frequent Collection.

Less frequent information collection would decrease the margin of assurance that plants

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 
4

frequently, the likelihood of detecting poor operation and maintenance of control equipment and 

noncompliance would decrease.

(e) General Guidelines.

None of these reporting or recordkeeping requirements violate any of the regulations 

established by the Office of Management and Budget (OMB) at 5 CFR 1320.5.

(f) Confidentiality.

Some respondents may consider production rate or concentration data to be confidential. 

Any such 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).

(g) Sensitive Questions.

None of the reporting or recordkeeping requirements contain sensitive questions.

4. The Respondents and the Information Requested

(a) Respondents/NAICS Codes.

The respondents to the recordkeeping and reporting requirements are nitric acid plants. 

The North American Industry Classification System (NAICS) code for respondents affected by 

the standards is 325311, Nitrogenous Fertilizer Manufacturing.

(b) Information Requested.

(i) Data Items, Including Recordkeeping Requirements. All data in this ICR that is 

recorded and/or reported is required by NSPS for Nitric Acid Plants for Which Construction, 

Reconstruction, or Modification Commenced After February 2011 (40 CFR part 60, subpart Ga).

A source must make the following reports:

Reports for 40 CFR part 60, subpart Ga

Notification of construction or modification application 60.6(a)

Notification of construction/reconstruction 60.7(a)(1)

Initial notifications 60.7(a)(3)

Notification of actual startup. 60.7(a)(3)

Physical or operational change. 60.7(a)(4)
5

Reports for 40 CFR part 60, subpart Ga

Notification of demonstration of continuous monitoring system 60.7(a)(5)

Initial performance test results. 60.8(a), 60.77a(a)

Initial performance test. 60.8(d), 60.73a(f)

Compliance status. 60.7(a)(7)

Malfunction report. 60.7(b), 60.77a(f)

NOX emission rates that are not in compliance with the emission 

standard.

60.77a(b)(2)

A source must maintain the following records:

Recordkeeping for 40 CFR part 60, subpart Ga

Malfunctions and periods where the continuous monitoring system is 

inoperative.

60.76a(f)

Records are required to be retained for two (2) years. 60.7(f)

Records of ongoing monitoring. 60.7(f)

Record daily production and nitric acid concentration. 60.76a(b)(2)

Records of noncompliance with the emission standard and description 

of corrective action.

60.76a(c) and (d)

Electronic Reporting

Currently, sources are using monitoring equipment that provides automated parameter 

data, e.g., continuous emissions monitoring. Although personnel at the affected facility must 

evaluate the data, this type of monitoring equipment has significantly reduced the burden 

associated with monitoring and recordkeeping. In addition, some regulatory agencies are setting 

up electronic reporting systems to allow sources to report electronically which is reducing the 

reporting burden. However, electronic reporting systems are still not widely used by the 

regulatory agencies. It is estimated that approximately 10 percent of the respondents will use 

electronic reporting.

(ii) Respondent Activities. The respondent activities required by subpart Ga are listed 

in the following tables.

Respondent Activities

Read instructions.

Install, calibrate, maintain, and operate Continuous Emission Rate Monitoring Systems

(CERMS), which include NOX and gas flow rate monitors.
6

Respondent Activities

Write the notifications and reports listed above.

Enter information required to be recorded above.

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

Transmit or otherwise disclose the information.

Train personnel on CERMS operation and maintenance.

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

Information Management

(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.

Review reports, including performance test reports and reports documenting NOX emission 

rates that are not in compliance the standard in subpart Ga.

Review notifications, including construction/reconstruction commencement, actual startup, 

and performance test.

Review performance test results.

(b) Collection Methodology and Management.

Following notification of startup, the reviewing authority might 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 entered into the AIRS Facility Subsystem (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 and annual emission inventory data for 

over 125,000 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, store, retrieve, and 

analyze the data.

The records required by this regulation must be retained by the owner or operator for two 

years.
7

(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 potential small entities (i.e., small business) was taken into 

consideration during the development of the regulation. Due to technical considerations 

involving the process operation 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 requirements the minimum needed to ensure compliance and, therefore, cannot reduce 

them further for small entities. To the extent that larger business can use economies of scale to 

reduce their burden, the overall burden will be reduced.

(d) Collection Schedule.

The specific frequency for each information collection activity within this request is 

shown in Tables 1a through 1c: Respondent Burden of Reporting and Recordkeeping 

Requirements, NSPS for Nitric Acid Plants (40 CFR Part 60, Subpart Ga) for the first three years 

of the information collection.

6. Estimating the Burden and Cost of the Collection

Tables 1a-1c: Respondent Burden of Reporting and Recordkeeping Requirements, NSPS 

for Nitric Acid Plants (40 CFR part 60, subpart Ga) documents the computation of individual 

burdens for the recordkeeping and reporting requirements applicable to the industry for the 

subpart included in this ICR for each of the first 3 years. Table 1d contains a summary of the 

respondent burden costs and hours detailed in Tables 1a through 1c.

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 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.

(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 968 hours per year (3 Year Average Hours from 

Table 1d). These hours are based on Agency studies and background documents from the 

development of the regulation, Agency knowledge, and experience with the NSPS program, and 

any comments received.
8

(b) Estimating Respondent Costs.

(i) Estimating Labor Costs. Labor rates and associated costs are based on Bureau of 

Labor Statistics (BLS) data. Technical, management, and clerical average hourly rates for private 

industry workers were taken from the United States Department of Labor, Bureau of Labor 

Statistics, September 2010, “Table 2. Civilian Workers, by occupational and industry group,” 

available at http://www.bls.gov/news.release/ecec.t02.htm. Wages for occupational groups are 

used as the basis for the labor rates with a total compensation of $46.82 per hour for technical, 

$49.14 per hour for managerial, and $23.41 per hour for clerical. These rates represent salaries 

plus fringe benefits and do not include the cost of overhead. An overhead rate of 110 percent is 

used to account for these costs. The fully-burdened hourly wage rates used to represent 

respondent labor costs are: technical at $98.32, management at $103.19, and clerical at $49.16.

(ii) Estimating Capital and Operations and Maintenance (O&M) Costs. The capital 

costs associated with the information collection requirements will include the costs to conduct 

performance tests, startup costs for CERMS, and purchase file cabinets for keeping records. The 

rule will require an initial performance test for each new nitric acid plant. The annual operation 

and maintenance costs are the ongoing costs to maintain the monitors and other costs such as 

photocopying and postage.

The annual average capital/startup costs for CERMS that will be used to control NOx

emissions is $136,070 (costs derived from EPA Model) with an annual operations and 

maintenance costs of $23,488.

The total respondent costs have been calculated as the addition of the capital/startup 

costs, and the annual operation and maintenance costs. The average annual cost for 

capital/startup and operation and maintenance costs to industry over the next three years of the 

ICR are estimated to be $159,558. The continuous monitoring costs that are included in this 

section consist only of those capital/startup and O&M costs that a source incurs as a result of the 

standard. Some continuous monitoring costs may not be included in this section. For instance, if 

a particular industry typically utilizes a control device that must have a continuous monitor (e.g., 

temperature, pressure drop, etc.) to function properly, and the recording of additional 

measurements beyond the minimum are required by the standard, then there is no capital/startup 

or O&M cost, but there is a labor cost to record the additional readings. Such a cost would not 

appear in this section, but in the industry burden Section 6(d) below.

It is assumed that the 4 newly constructed nitric acid plants will not be located at existing 

facilities. It is anticipated that new units will use CERMS for compliance with the proposed new 

NOx limit. Initial CERMS testing is usually conducted by an installation contractor such that the 

cost of the emissions testing is a capital cost. Testing costs are $15,019 for each NOx CEMS and 

$6,229 for a flow meter (assumes one flow meter per stack). The 4 new sources in this sector 

result in a total capital cost of approximately $76,496 for CERMS testing over the next three 

years.
9

(iii) Annualizing Capital Costs. The annualized capital costs include the costs for one 

year (1.2 units) for NOX CEMS, flow meters, and file cabinets. The annualized capital costs for 

equipment associated with NOX CEMS and flow meters were calculated using a 7 percent 

interest rate and a 10 year life (i.e., CRF of 0.1424). The annualized capital cost for file cabinets

was calculated using a 7 percent interest rate and a 15-year life (i.e., CRF of 0.1098). The total 

annualized capital costs total $42,776. The CEMS Monitoring Costs Spreadsheet can be found in 

the docket (See Section 6(g) for docket information).

(c) Estimating Agency Burden and Cost.

Tables 2a-2c: Burden and Cost to the Agency—NSPS for Nitric Acid Plants documents

the costs of this NSPS revision to the Agency for the first 3 years of the information collection.

The only costs to the Agency are those costs associated with analysis of the reported information. 

Publication and distribution of the information are part of the AFS program. Examination of 

records to be maintained by the respondents will occur as part of the periodic inspection of 

sources, which is part of EPA’s overall compliance and enforcement program. Table 2d contains 

a summary of the agency burden costs and hours detailed in Tables 2a-2c. The average annual 

Agency cost during the three years of the ICR is estimated to be $3,206.

The Agency labor rates are from the Office of Personnel Management (OPM) 2008

General Schedule which excludes locality rates of pay. These rates can be obtained from Salary 

Table 2011-GS, available on the OPM website at http://www.opm.gov/oca/11tables/html/gs_h.asp. 

The government employee labor rates are $15.63 per hour for clerical (GS-6, Step 3), $28.88 for 

technical (GS-12, Step 1), and $38.92 for managerial (GS-13, Step 5). These rates were increased 

by 60 percent to include fringe benefits and overhead. The fully-burdened wage rates used to 

represent Agency labor costs are: clerical at $25.01, technical at $46.21, and managerial at $62.27.

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

It is estimated that 4 newly constructed nitric acid production units will become subject to 

the proposed regulation in the next three years. Nitric acid production was estimated for 2006 

(TSD for Greenhouse Gas Reporting Rule), using the production growth of 6.5% from 2006 to 

2007 (ICIS) and the predicted production growth rate of 3% for 2007 through 2016 (ICIS). In the 

period from 2010 through 2016, the growth was approximately 1.6 million tons of nitric acid. 

Assuming 350 days per year, this equals approximately 4,586 tpd of nitric acid production. 

Using the model plants, the estimate of 4,586 tpd equals 2 production trains that produce 300 

tpd, and 4 production trains that produce 1,000 tpd over the five year period after promulgation.

The total annual number of responses for the monitoring, recordkeeping, and reporting 

requirements in subpart Ga is 22 for the 4 newly constructed nitric acid units.

The total annual labor costs are $91,808. Details upon which this estimate is based appear 

in Table 1a.
10

(e) Bottom Line Burden Hours and Cost Tables.

The bottom line burden hours and cost tables for both the Agency and the respondents are 

attached. The annual public reporting and recordkeeping burden for this collection of 

information is estimated to average 44.8 hours per response.

(f) Reasons for Change in Burden.

There is no change in burden because this is a new Information Collection.

(g) Burden Statement.

The annual public reporting and recordkeeping burden for this collection of information 

is estimated to average 44.8 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.

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’s 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-OAR-2007-0877. An electronic version of the public docket is 

available at www.regulations.gov which may be used to obtain a copy of the draft collection of 

information, submit or view public comments, access the index listing of the contents of the 

docket, and to access those documents in the public docket that are available electronically. 

When in the system, select “search,” then key in Docket ID Number EPA-HQ-OAR-2007-0877. 

The documents are also available for public viewing at the EPA Docket Center, EPA West,
