SUPPORTING STATEMENT

ENVIRONMENTAL PROTECTION AGENCY

NSPS for Nonmetallic Mineral Processing (40 CFR Part 60, Subpart OOO) (Renewal)

1. Identification of the Information Collection

1(a) Title of the Information Collection

NSPS for Nonmetallic Mineral Processing (40 CFR Part 60, Subpart OOO) (Renewal), EPA ICR 

Number 1084.13, OMB Control Number 2060-0050.

1(b) Short Characterization/Abstract

The New Source Performance Standards (NSPS) for the regulation published at 40 CFR 

Part 60, Subpart OOO were proposed on August 31, 1983, promulgated on August 1, 1985, and 

most recently amended on April 28, 2009. These regulations apply to the following affected 

facilities in fixed or portable nonmetallic mineral processing plants: each crusher, grinding mill, 

screening operation, bucket elevator, belt conveyor, bagging operation, storage bin, and enclosed 

truck or railcar loading station, which commenced construction, modification or reconstruction 

after August 31, 1983. Also, crushers and grinding mills at hot mix asphalt facilities that reduce 

the size of nonmetallic minerals embedded in recycled asphalt pavement and subsequent affected 

facilities up to, but not including, the first storage silo or bin are subject to the provisions of the 

subpart. This information is being collected to assure compliance with 40 CFR Part 60, Subpart 

OOO.

The provisions of Subpart OOO do not apply to the following operations: facilities 

located in underground mines, wet material processing operations, and plants without crushers or 

grinding mills. An affected facility that is subject to the provisions of either Subparts F or I, or 

that follows in the process any facility subject to the provisions of Subparts F or I of this part, is 

not subject to the provisions of this subpart. In addition, the following plants are not subject to 

Subpart OOO: fixed sand and gravel plants and crushed stone plants with capacities of 23 

megagrams per hour (25 tons per hour) or less; portable sand and gravel plants and crushed stone 

plants with capacities of 136 megagrams per hour (150 tons per hour) or less; and common clay

plants and pumice plants with capacities of 9 megagrams per hour (10 tons per hour) or less. 

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 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 
2

States Environmental Protection Agency (EPA) regional office.

Over the next three years, an average of 4,896 existing respondents per year will be 

subject to the standard, and 66.4 additional new respondents per year will become subject to the 

standard.

The Office of Management and Budget (OMB) approved the currently active ICR 

without any “Terms of Clearance.”

The term “Affected Public” applies to any publicly owned and operated fixed or portable 

nonmetallic mineral processing plant, and may be found in Table 1: Annual Respondent Burden 

and Cost – NSPS for Nonmetallic Mineral Processing (40 CFR Part 60, Subpart OOO) 

(Renewal). The burden to the “Federal Government” burden is attributed entirely to work 

performed by federal employees or government contractors, and may be found in Table 2: 

Average Annual EPA Burden and Cost – NSPS for Nonmetallic Mineral Processing (40 CFR 

Part 60, Subpart OOO) (Renewal).

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/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 
3

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 emissions from nonmetallic mineral 

processing plants (NMPPs) cause or contribute to air pollution that may reasonably be 

anticipated to endanger public health or welfare. Therefore, the NSPS were promulgated for this 

source category at 40 CFR Part 60, Subpart OOO.

2(b) Practical Utility/Users of the Data

The recordkeeping and reporting requirements in the standards ensures 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 the standards at all times.

The notifications required in the 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 and that the standards are being met. The performance test may also be 

observed.

The required semiannual compliance reports are used to determine periods of excess 

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

compliance determinations.

3. Nonduplication, Consultations, and Other Collection Criteria

The requested recordkeeping and reporting are required under 40 CFR Part 60, Subpart 

OOO.

3(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 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 exists.
4

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 (79 FR 30117) on May 27, 2014. 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 Enforcement and Compliance History Online (ECHO), which is 

operated and maintained by EPA's Office of Compliance. ECHO is EPA’s database for the 

collection, maintenance, and retrieval of all compliance data.

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

to comment on the burden associated with the standard when it was being developed and further 

amended, and the standard has been previously reviewed to determine the minimum information 

needed for compliance purposes. For the current renewal, EPA contacted the National Stone, 

Sand, and Gravel Association (NSSGA) at (703) 525-8788 and the Industrial Minerals 

Association - North America (IMA-NA) at (240) 457-0200.

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 

will be safeguarded according to the Agency policies set forth in Title 40, Chapter 1, Part 2, 

Subpart B - Confidentiality of Business Information (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).

4(b) Information Requested

(i) Data Items

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

Mineral Processing (40 CFR Part 60, Subpart OOO).

A source must make the following notifications:

Notifications

Notification of actual startup 60.7(a)(3), 60.676(i)

Physical or operational change 60.7(a)(4)

Notification of initial performance test 60.8(d), 60.672

A source must make the following reports:

Reports

Initial performance test results 60.8(a), 60.676(f)

Repeat performance test results 60.8(a), 60.11, 60.675

Report of replacement activities 60.676(a)

Semiannual reports of when scrubber pressure losses and liquid flow 

rates are 30 percent below the average determined from performance 

testing

60.676(d), 60.676(e)

Report of process change 60.676(g)
7

A source must keep the following records:

Recordkeeping

Startups, shutdowns, malfunctions, periods where the continuous 

monitoring system is inoperative

60.7(b)

Records are required to be retained for two years and kept onsite 60.7(f)

Records of inspections and monitoring

60.7(f), 60.674(b), 

60.674(c), 60.676(b), 

60.676(d)

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.

Perform initial performance test using appropriate Reference Method, 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 

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.
8

Respondent Activities

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 and reporting equipment that provide 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

Observe initial performance tests and repeat performance tests, if necessary.

Review notifications and reports, including performance test reports and excess emissions 

reports, required to be submitted by industry.

Audit facility records.

Input, analyze, and maintain data in Integrated Compliance Information System (ICIS) and 

ECHO. 

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 semiannual reports are used for 

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

determinations.
9

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

The majority of respondents are estimated to be small entities. The impact on small 

entities (i.e., small businesses) was taken into consideration during the development of the 

regulation by exempting wet material processing operations, simplifying certain notification 

requirements, and selecting relatively low-cost repeat testing and monitoring provisions. In 

addition, certain plants operating at small capacities were exempted from Subpart OOO due to 

economic considerations when the standards were originally developed. 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 Nonmetallic Mineral 

Processing (40 CFR Part 60, Subpart OOO) (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 14,120 (Total Labor Hours from Table 1). These 
10

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 $129.93 ($61.87 + 110%) 

Technical $103.97 ($49.51 + 110%)

Clerical $51.79 ($24.66 + 110%)

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

2014, “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 standards 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 the regulation. The annual operation and maintenance (O&M) costs 

are the ongoing costs to maintain the monitors and other costs such as photocopying and postage.

N/A – Not Applicable

a Of the 66.4 new respondents per year, EPA estimates 60.9 will be in the crushed/broken stone and sand/gravel 

industrial sectors and 5.5 will be in other industrial sectors.

b These are annualized costs for all new respondents. The capital cost associated with testing was annualized 

assuming a 7% interest rate and 5-year life (i.e., capital recovery factor (CRF) of 0.2439). The annualized capital 

cost for file cabinets was calculated using a 7% interest rate and a 15-year life (i.e., CRF of 0.1098).

c EPA estimates a testing cost of $216.67 per 30-minute Method 9 test. EPA assumes each plant in the 

crushed/broken stone and sand/gravel industrial sectors has 22 emissions points requiring Method 9 testing; 

therefore, the capital/startup cost per respondent is $4,767 (rounded) ($216.67x22 = 4,766.74).

d Existing sources in the crushed/broken stone and sand/gravel industrial sectors, built in 2008 or later, must repeat 

performance testing every five years. Over the next three years (2016 to 2018), an average of 60.9 existing sources 

per year will repeat performance testing. These existing sources were the new sources that conducted initial 

performance testing in 2011, 2012, and 2013.

e EPA estimates a testing cost of $7,000 per Method 5 test. EPA assumes each plant in other industrial sectors 

subject to the rule has 9 emission points requiring Method 5 testing; therefore, the capital/startup cost per 

respondent is $63,000 ($7,000x9 = $63,000).

The total capital/startup costs for this ICR are $228,000.

The total operation and maintenance (O&M) costs for this ICR are $0. This is the total of 

column G. 

The average annual cost for capital/startup and O&M costs to industry over the next three 

years of the ICR is estimated to be $228,000. These are capital/startup 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 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 

$221,000. 
12

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

Managerial $62.90 (GS-13, Step 5, $39.31 + 60%) 

Technical $46.67 (GS-12, Step 1, $29.17 + 60%)

Clerical $25.25 (GS-6, Step 3, $15.78 + 60%)

These rates are from the Office of Personnel Management (OPM), 2014 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: Average Annual EPA Burden and Cost – NSPS for Nonmetallic 

Mineral Processing (40 CFR Part 60, Subpart OOO) (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 

4,830 existing respondents will be subject to the standard. It is estimated that an additional 66.4 

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

in the table below, is 4,896 (rounded).

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

years covered by this ICR.

found below in Table 1: Annual Respondent Burden and Cost – NSPS for Nonmetallic Mineral 

Processing (40 CFR Part 60, Subpart OOO) (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 14,120. Details regarding these estimates may be found 

in Table 1: Annual Respondent Burden and Cost – NSPS for Nonmetallic Mineral Processing 

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

Furthermore, the annual public reporting and recordkeeping burden for this collection of 

information is estimated to average 3 hours per response.
14

The total annual capital/startup and O&M costs to the regulated entity are $227,838. 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 the next three years is estimated to be 

4,850 labor hours at a cost of $221,000. See Table 2: Average Annual EPA Burden and Cost –

NSPS for Nonmetallic Mineral Processing (40 CFR Part 60, Subpart OOO) (Renewal).

6(f) Reasons for Change in Burden

There is an increase in the respondent burden from the most recently approved ICR. This 

increase is not due to any program changes. The previous ICR reflected burdens and costs 

associated with initial activities for subject facilities, including performance testing and 

establishing recordkeeping systems. This ICR accounts for the additional burden incurred by 

existing sources that must conduct five-year performance testing during this ICR period. This 

ICR also reflects an increase in the total number of respondents due to industry growth. The 

overall result is an increase in total burden hours and costs.

EPA has also updated the capital/startup and O&M costs to reflect the additional costs 

incurred by existing sources that must conduct five year performance tests. This adjustment 

resulted in an overall increase in the total capital/startup and O&M cost.

There is a decrease in Agency burden from the most recently approved ICR. The 

previous ICR’s burden calculations largely overestimated the number of existing sources 

submitting performance test reports to EPA. We have adjusted the number of sources 

accordingly. This adjustment resulted in the overall decrease in the Agency burden.

6(g) Burden Statement

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

is estimated to average 3 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

a

 EPA estimates an average of 4,896 existing sources will be subject to the standard and 66.4 new sources per year will become subject over the next three years. 

These estimates are based on model plant parameters used in development of the original promulgated NSPS and 2005/2006 USGS production data. Of the 66.4 

new respondents per year, EPA estimates 60.9 will be in the crushed/broken stone and sand/gravel industrial sectors and 5.5 will be in other industrial sectors.

b

 This ICR uses the following labor rates: $103.97 (technical), $129.93 (managerial), and $51.79 (clerical). These rates are from the United States Department of 

Labor, Bureau of Labor Statistics, June 2014, “Table 2. Civilian Workers, by occupational and industry group.” The rates are from column 1, “Total 

compensation.” They have been increased by 110 percent to account for the benefit packages available to those employed by private industry.

c

 Monitoring for wet suppression involves checking that water is actually flowing. EPA estimates it will occur on a monthly basis and take 10 minutes per check. 

Wet suppression is expected to be used in the crushed/broken stone and sand/gravel industrial sectors.

d

 EPA estimates it will take each respondent one hour four times per year to complete Method 22 readings. All other industry sectors except for crushed/broken 

stone and sand/gravel are expected to use baghouses and will employ baghouse Method 22 readings to comply with the periodic monitoring requirements.

e

 Includes 8 hours to develop and review performance test report and 22 hours to plan for performance testing. The time required to conduct Method 5 and

Method 9 performance tests is included under capital costs because a contractor is typically hired to perform these tests.

f

 EPA assumes 25% of initial performance tests will be repeated due to failure (66.4 x 0.25 = 16.6).
18

g

 Existing sources in the crushed/broken stone and sand/gravel industrial sectors, built in 2008 or later, must repeat performance testing every five years. Over the 

next three years (2016 to 2018), an average of 60.9 existing sources per year will repeat performance testing. These existing sources were the new sources that 

conducted initial performance testing in 2011, 2012, and 2013.

 This ICR uses the following labor rates: $46.67 (technical), $62.90 (managerial), and $25.25 (clerical). These rates are from the Office of Personnel 

Management (OPM), 2014 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.

c

 EPA assumes 25% of initial performance tests will be repeated due to failure (66.4 x 0.25 = 16.6).

d

 Includes EPA review of initial and repeat performance tests conducted by new sources (66.4 + 16.6 = 83).
