SUPPORTING STATEMENT

ENVIRONMENTAL PROTECTION AGENCY

NSPS for Phosphate Rock Plants (40 CFR Part 60, Subpart NN) (Renewal)

1. Identification of the Information Collection

1(a) Title of the Information Collection

NSPS for Phosphate Rock Plants (40 CFR Part 60, Subpart NN) (Renewal),

EPA ICR Number 1078.09, OMB Number 2060-0111

1(b) Short Characterization/Abstract

The New Source Performance Standards (NSPS) for Phosphate Rock Plants (40 CFR 60, 

subpart NN) were proposed on September 21, 1979, and promulgated on April 16, 1982. These 

regulations apply to the following new facilities at phosphate rock plants with capacities greater 

than 4 tons per hour: dryers, calciners, grinders, and ground rock handling and storage facilities, 

except those facilities producing or preparing phosphate rock solely for consumption in 

elemental phosphorus production. New facilities include those that commenced construction, 

modification or reconstruction after the date of proposal. This information is being collected to 

assure compliance with 40 CFR part 60, subpart NN.

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 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.

Based on our consultations with industry representatives, there is an average of one 

affected facility 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 years, an average of 13 facilities per year will be subject to the 

standard, and it is estimated that one additional source will become subject to the standard in the 

next three years.

There are approximately 13 phosphate rock plants in the United States, which are all 
2

publicly owned and operated by the Phosphate Rock industry. None of the 13 plants in the 

United States are owned by either state, local, tribal, or the Federal government. They are all 

owned and operated solely by privately owned for-profit businesses. The burden to the “Affected 

Public” may be found below in Table 1: Annual Respondent Burden and Cost, NSPS for 

Phosphate Rock Plants (40 CFR Part 60, Subpart NN) (Renewal). The burden to the Federal 

government is attributed entirely to work performed by Federal employees or government 

contractors; this burden may be found below in Table 2: Annual Agency Burden and Cost, NSPS 

for Phosphate Rock Plants (40 CFR Part 60, Subpart NN) (Renewal).

The active (previous) ICR had the following Terms of Clearance (TOC):

“As part of its submission, EPA should verify that the wage rates referenced in Sections 

6(b) and 6(c) of the supporting statement have been updated to current values and properly

loaded to include overhead, consistent with current EPA and OMB guidelines.”

The EPA has addressed these terms of clearance for this ICR by using the most recent 

labor rates in Sections 6(b) and 6(c).

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

four years. 

In addition, section 114(a) states that the Administrator may require any owner or 

operator subject to any requirement of this Act to:

(A) Establish and maintain such records; (B) make such reports; 

(C) install, use, and maintain such monitoring equipment, and use 

such audit procedures, or methods; (D) sample such emissions (in 

accordance with such procedures or methods, at such locations, at 

such intervals, during such periods, and in such manner as the 

Administrator shall prescribe); (E) keep records on control 
3

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, particulate matter (PM) emissions from phosphate rock 

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

health or welfare. Therefore, the NSPS was promulgated for this source category at 40 CFR part 

60, subpart NN.

2(b) Practical Utility/Users of the Data

The recordkeeping and reporting requirements in the standard ensure compliance with the 

applicable regulations which where 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 standard. Continuous emission monitors are used to ensure 

compliance with the standard at all times. During the performance test, a record of the operating 

parameters under which compliance was achieved may be recorded and used to determine 

compliance in place of a continuous emission monitor. 

The notifications required in the standard are used to inform the Agency or delegated 

authority when a source becomes subject to the requirements of the regulations. The reviewing 

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

installed and operated, that leaks are being detected and repaired, and that the standard is being 

met. The performance test may also be observed.

The required semiannual reports are used to determine periods of excess emissions, 

identify problems at the facility, verify operation/maintenance procedures and for compliance 

determinations.

3. Non-duplication, Consultations, and Other Collection Criteria

The requested recordkeeping and reporting are required under 40 CFR part 60, subpart 

NN.

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, no duplication 
4

exists.

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 (75 FR 30812) on June 2, 2010. No comments were received on the 

burden published in the Federal Register.

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 the standard, is the Air Facility System (AFS) which is operated and maintained by

the EPA Office of Compliance. AFS is the EPA database for the collection, maintenance, and 

retrieval of all compliance data. The growth rate for the industry is based on our consultations 

with the Agency’s internal industry experts. Approximately 13 respondents will be subject to the 

standard over the three year period covered by this ICR.

Industry trade associations and other interested parties were provided an opportunity to 

comment on the burden associated with the standard as it was being developed and the standard 

has been previously reviewed to determine the minimum information needed for compliance 

purposes.

It is our policy to respond after a thorough review of comments received since the last 

ICR renewal as well as those submitted in response to the first Federal Register notice. In this 

case, no comments were received.

3(d) Effects of Less Frequent Collection

Less frequent information collection would decrease the margin of assurance that 

facilities are continuing to meet the standards. Requirements for information gathering and 

recordkeeping are useful techniques to ensure that good operation and maintenance practices are 

applied and emission limitations are met. If the information required by these standards was 

collected less frequently, the proper operation and maintenance of control equipment and the 

possibility of detecting violations would be less likely.

3(e) General Guidelines

These reporting or recordkeeping requirements do not violate any of the regulations 

promulgated by OMB under 5 CFR part 1320, section 1320.5.

3(f) Confidentiality

Any information submitted to the Agency for which a claim of confidentiality is made 
5

will be safeguarded according to the Agency policies set forth in title 40, chapter 1, part 2, 

subpart B - Confidentiality of Business Information (CBI) (see 40 CFR 2; 41 FR 36902, 

September 1, 1976; amended by 43 FR 40000, September 8, 1978; 43 FR 42251, September 20, 

1978; 44 FR 17674, March 23, 1979).

3(g) Sensitive Questions

The reporting or recordkeeping requirements in the standard do not include sensitive 

questions.

4. The Respondents and the Information Requested

4(a) Respondents/SIC Codes

The respondents to the recordkeeping and reporting requirements are phosphate rock 

plants. The United States Standard Industrial Classification (SIC) code for the respondents 

affected by the standards is SIC code 1475, which corresponds to the North American Industry

Classification System (NAICS) code 212393 for phosphate rock plants.

40 CFR Part 60, Subpart NN SIC Codes NAICS Codes

Phosphate Rock 1475 212393

4(b) Information Requested

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

established by OMB at 5 CFR part 1320, section 1320.5.

(i) Data Items

In this ICR, all the data that is recorded or reported is required by the NSPS for Phosphate 

Rock Plants (40 CFR part 60, subpart NN). 

A source must make the following reports:

Notifications

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

Notification of actual startup 60.7(a)(3)

Notification of physical or operational change which may increase the 

emission rate

60.7(a)(4)

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

Notification of initial performance test 60.8(d)

Report on initial performance test 60.8(a)

Semiannual report on excess emissions 60.7(c)

A source must keep the following records:
6

Recordkeeping

Maintain records of startups, shutdowns, malfunctions, periods where the 

continuous monitoring system is inoperative

60.7(b)

Maintain all records for two years 60.7(f)

Electronic Reporting

Some of the respondents are using monitoring equipment that automatically records 

parameter data. Although personnel at the affected facility must still evaluate the data, internal 

automation has significantly reduced the burden associated with monitoring and recordkeeping at 

a plant site. 

Also, regulatory agencies in cooperation with the respondents, continue to create 

reporting systems to transmit data electronically. However, electronic reporting systems are still 

not widely used. At this time, it is estimated that approximately 10 percent of the respondents 

use electronic reporting.

(ii) Respondent Activities

Respondent Activities

Read instructions.

Install, calibrate, maintain, and operate continuous monitoring system (CMS) for opacity, or 

for pressure drop and liquid supply pressure for wet scrubber.

Perform initial performance test, Reference Methods 5, and 9, and repeat performance tests if 

necessary.

Write the notification and reports listed above.

Enter information required to be recorded above.

Submit the required reports developing, acquiring, installing, and utilizing technology and 

systems for the purpose of collecting, validating, and verifying information.

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

maintaining information.

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

providing information.

Adjust the existing ways to comply with any previously applicable instructions and 

requirements.

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

Transmit, or otherwise disclose the information.

Currently, sources are using monitoring equipment that provides parameter data in an 

automated way (e.g., continuous parameter monitoring system). Although personnel at the 

source still need to evaluate the data, this type of monitoring equipment has significantly reduced 

the burden associated with monitoring and recordkeeping.

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

Information Management

5(a) Agency Activities

EPA conducts the following activities in connection with the acquisition, analysis, 

storage, and distribution of the required information.

Agency Activities

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 Air Facility System (AFS).

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 and note the operating conditions under which compliance was 

achieved. Data and records maintained by the respondents are tabulated and published for use in 

compliance and enforcement programs. The semiannual reports 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 AFS which is operated and 

maintained by the EPA Office of Compliance. AFS is the EPA database for the collection, 

maintenance, and retrieval of compliance data for approximately 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/operator for two 

years.

5(c) Small Entity Flexibility

The majority of the respondents are large entities (i.e., large businesses). However, the 

impact on small entities (i.e., small businesses,) was taken into consideration during the 

development of the regulation. Due to technical considerations involving the process operations 

and the types of control equipment employed, the recordkeeping and reporting requirements are 

the same for both small and large entities. The Agency considers these to be the minimum 

requirements needed to ensure compliance and, therefore, cannot reduce them further for small 

entities. To the extent that larger businesses can use economies of scale to reduce their burden, 

the overall burden will be reduced.

5(d) Collection Schedule

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

shown in below Table 1: Annual Respondent Burden and Cost, NSPS for Phosphate Rock Plants 

(40 CFR Part 60, Subpart NN) (Renewal).

6. Estimating the Burden and Cost of the Collection

Table 1 documents the computation of individual burdens for the recordkeeping and 

reporting requirements applicable to the industry for the subpart included in this 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 not conduct or sponsor, and a person is not required to respond to, a 

collection of information unless it displays a currently valid OMB Control Number.

6(a) Estimating Respondent Burden

The average annual burden to industry over the next three years from these recordkeeping 

and reporting requirements is estimated to be 1,602 labor hours. The recordkeeping hours shown 

below in Table 1 are 1,338. The reporting requirement hours shown below in Table 1 are 264. 

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 $116.05 ($55.26 + 110%) 

Technical $97.21 ($46.29 + 110%)

Clerical $48.87 ($23.27 + 110%)

These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 

2010, “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 is both labor costs, which are addressed elsewhere in this ICR, and the costs 
9

associated with continuous monitoring. The capital/startup costs are one-time costs 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.

the above table. 

The total operation and maintenance (O&M) costs for this ICR are $111,972. This is the 

total of column G.

6(c) Estimating Agency Burden and Cost

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

information. The EPA compliance and enforcement program includes activities such as the 

examination of records maintained by the respondents, periodic inspection of sources of 

emissions, and the publication and distribution of collected information. 

The average annual Agency cost during the three years of the ICR is estimated to be 

$6,298.

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

Managerial $62.27 (GS-13, Step 5, $38.92 + 60%) 

Technical $46.21 (GS-12, Step 1, $28.88 + 60%)

Clerical $25.01 (GS-6, Step 3, $15.63 + 60%)

These rates are from the Office of Personnel Management (OPM), 2010 General Schedule, which 

excludes locality rates of pay. The rates have been increased by 60 percent to account for the 

benefit packages available to government employees. Details upon which this estimate is based 

appear below in Table 2: Annual Agency Burden and Cost, NSPS for Phosphate Rock Plants (40 

CFR Part 60, Subpart NN) (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

13 existing respondents will be subject to the standard. It is estimated that an additional one 
10

respondents per year will become subject. The overall average number of respondents, as shown 

in the table below, is 13 per year.

The number of respondents is calculated using the following table that addresses the three 

years covered by this ICR.

The number of Total Annual Responses is 29. This is the number in column E of the 

Respondent Universe and Number of Responses per year in table above.

The total annual labor costs are $150,354. Details regarding these estimates may be 

found below in Table 1: Annual Respondent Burden and Cost, NSPS for Phosphate Rock Plants 

(40 CFR Part 60, Subpart NN) (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 in Tables 1 and 2 (below), respectively, and summarized below. 

(i) Respondent Tally

The total annual labor hours are 1,602 labor hours. Details regarding these estimates may

be found below in Table 1: Annual Respondent Burden and Cost, NSPS for Phosphate Rock 

Plants (40 CFR Part 60, Subpart NN) (Renewal). Furthermore, the annual public reporting and 

recordkeeping burden for this collection of information is estimated to average 55 hours per 

response.

The total annual capital/startup and O&M costs to the regulated entity are $124,182. 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 140 

labor hours at a cost of $6,298. See below Table 2: Annual Agency Burden and Cost, NSPS for 

Phosphate Rock Plants (40 CFR Part 60, Subpart NN) (Renewal).

6(f) Reasons for Change in Burden

There is no change in the labor hours, or in the capital/startup and operation and 

maintenance costs in this ICR compared to the previous ICR. This is due to two considerations: 

1) the regulations have not changed over the past three years and are not anticipated to change 

over the next three years; and 2) the growth rate for the industry is very low, negative, or nonexistent.

The increase in labor cost to Respondents and the Agency is due to labor rate adjustments 

to reflect the most recent available estimates. 

6(g) Burden Statement

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

is estimated to average 55 hours per response. Burden means the total time, effort, or financial 
12

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 regulations are listed at 40 CFR part 9 and 48 CFR chapter 15.

Assumptions:

a

 We have assumed that the average number of respondents that will be subject to the rule will be 13.33. It is estimated that one new source will become subject to the 

rule over the three-year period of this ICR.

b

 This ICR uses the following labor rates: $116.05 per hour for Executive, Administrative, and Managerial labor; $97.21 per hour for Technical labor, and $48.87 per 

hour for Clerical labor. These rates are from the United States Department of Labor, Bureau of Labor Statistics, December 2003, “Table 2. Civilian Workers, by 

Occupational and Industry group.” The rates are from column 1, “Total Compensation.” The rates have been increased by 110 percent to account for the benefit packages 

available to those employed by private industry.

c

 We have assumed that 20 percent of initial performance test will be repeated due to failure.

d

 We have assumed that no facility will be engaged in physical or operational changes.

e

 We have assumed that it will take each respondent 2 hours each to write CMS notification report.

f

 We have assumed that each respondent will take 8 hours, two times per year, to write semiannual report on excess emissions.

g

 We have assumed that each respondent will take 15 minutes per day to record operating parameters information.
