NSPS for Metallic Mineral Processing Plants (40 CFR Part 60, Subpart LL) (Renewal)

1. Identification of the Information Collection

1(a) Title of the Information Collection

NSPS for Metallic Mineral Processing Plants (40 CFR Part 60, Subpart LL) (Renewal), EPA 

ICR Number 0982.11, OMB Control Number 2060-0016.

1(b) Short Characterization/Abstract

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

Part 60, Subpart LL were proposed on August 24, 1982, promulgated on February 21, 1984, and 

most recently amended on February 27, 2014. The recent amendment promulgated technical and 

editorial corrections for source testing of emissions and operations. It does not impose any new 

or additional information collection burden on subject sources. These regulations apply to the 

following facilities at metallic mineral processing plants: each crusher and screen at open-pit 

mines and each crusher, screen, bucket elevator, conveyor belt transfer point, thermal dryer, 

product packaging station, storage bin, enclosed storage area, and truck loading and unloading 

station at mills or concentrators commencing construction, modification or reconstruction after 

the date of proposal. The NSPS does not apply to facilities located in underground mines or 

uranium ore beneficiation processing plants. This information is collected to assure compliance 

with 40 CFR Part 60, Subpart LL.

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.

Over the next three years, an average of 20 respondents per year 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. It is possible that one existing facility undergo 

reconstruction or a physical/operational change. If so, they will be such required to submit initial 

notifications and conduct initial performance testing. 

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. 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.
2

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

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 

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 emissions from metallic mineral 

processing plants 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 LL.

2(b) Practical Utility/Users of the Data

The recordkeeping and reporting requirements in the standard 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.
3

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. Nonduplication, Consultations, and Other Collection Criteria

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.

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

Industry experts have been consulted, and the Agency’s internal data sources and 

projections of industry growth over the next three years have been considered. The primary

source of information as reported by industry, in compliance with the recordkeeping and 

reporting provisions in the standard, is the Online Tracking Information System (OTIS), which is 

operated and maintained by the EPA Office of Compliance. OTIS is the EPA database for the 

collection, maintenance, and retrieval of all compliance data. 

Consultations with industry representatives (i.e., respondents) also were conducted to 

determine if there is any way for EPA to reduce the recordkeeping and reporting burden or 

improve the language in the standard to make it easier to comply. In developing this ICR, we 
4

contacted both the Society for Mining, Metallurgy, and Exploration at (303) 948-4200 and the

National Mining Association at (202) 721-4100.

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

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

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).

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 metallic mineral 

processing plants. The United States Standard Industrial Classification (SIC) codes and the 

corresponding North American Industry Classification System (NAICS) codes for respondents 

affected by the standard are listed in the following table.

Standard

4(b) Information Requested

(i) Data Items

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

Mineral Processing Plants (40 CFR Part 60, Subpart LL).

A source must make the following notifications:

Notifications

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

Notification of actual startup 60.7(a)(3)

Notification of initial performance test 60.8(d)

Notification of physical or operational changes 60.7(a)(4)

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

A source must make the following reports:

Reports

Performance test results, including CMS demonstration results 60.8(a) and 

60.385(a)

Semiannual reports when wet scrubber measurements deviate by more 

than 30 percent from their respective averages, as measured during the 

most recent performance test

60.385(c)

A source must keep the following records:
6

Recordkeeping

Startups, shutdowns, and malfunctions; periods where the CMS is 

inoperative

60.7(b)

Weekly measurements of wet scrubber gas stream pressure change and 

scrubbing liquid flow rate

60.385(b)

Records retention for at least 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 CMS for opacity, or wet scrubber pressure drop and 

liquid supply pressure.

Perform initial performance test, Reference Method 5, 9, 17 tests, 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 
7

Respondent Activities

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 and reporting equipment that provide parameter 

data in an automated way (e.g., continuous parameter monitoring systems). 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 the Online Tracking Information System (OTIS). 

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.
8

Information contained in the reports is entered into OTIS, which is operated and 

maintained by EPA's Office of Compliance. OTIS is EPA’s database for the collection, 

maintenance, and retrieval of compliance data for approximately 125,000 industrial and 

government-owned facilities. EPA uses the OTIS 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

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

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

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

and the 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 Metallic Mineral 

Processing Plants (40 CFR Part 60, Subpart LL) (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.

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 2,306 hours. 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
9

(i) Estimating Labor Costs

This ICR uses the following labor rates: 

Managerial $128.02 ($60.98 + 110%)

Technical $101.05 ($48.12 + 110%)

Clerical $51.37 ($24.46 + 110%)

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

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 standard 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 monitor(s) and other costs such as photocopying and

postage.

above table. 

The total operation and maintenance (O&M) costs for this ICR are $13,000. 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 $13,000.

6(c) Estimating Agency Burden and Cost
10

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

$10,484. 

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 Metallic 

Mineral Processing Plants (40 CFR Part 60, Subpart LL) (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

20 existing respondents will be subject to the standard. No additional respondents per year will 

become subject. The overall average number of respondents, as shown in the table below, is 20 

per year.

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

years covered by this ICR.

The total annual labor costs are $225,739. Details regarding these estimates may be 

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

Processing Plants (40 CFR Part 60, Subpart LL) (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
12

The total annual labor hours are 2,306. Details regarding these estimates may be found in 

Table 1: Annual Respondent Burden and Cost – NSPS for Metallic Mineral Processing Plants 

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

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

information is estimated to average 51 hours per response.

The total annual capital/startup and O&M costs to the regulated entity are $13,000. 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 230 

labor hours at a cost of $10,484. See Table 2: Average Annual EPA Burden and Cost – NSPS 

for Metallic Mineral Processing Plants (40 CFR Part 60, Subpart LL) (Renewal).

6(f) Reasons for Change in Burden

There is no change in the total estimated respondent burden compared with the ICR 

currently approved by OMB. 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 respondents is very low, negative, or non-existent. However, the 

number of responses has been increased by one from 44 to 45. This increase is due to a 

correction; the previous ICR did not account for notification of initial performance test in 

calculating the number of responses. 

6(g) Burden Statement

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

is estimated to average 51 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 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 
13

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-2014-0030. An electronic version of the public docket is

a

 On average, EPA estimates 20 existing sources will be subject to the NSPS. No new sources will become subject to the standard 

over the three-year period of this ICR. EPA also estimates one existing facility will undergo either a reconstruction or a physical or 

operational change such that it will be required to submit initial notifications and conduct initial performance testing.

b

 This ICR uses the following labor rates: $101.05 (technical), $128.02 (managerial), and $51.37 (clerical). These rates are from the 

United States Department of Labor, Bureau of Labor Statistics, March 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

 EPA assumes 20 percent of respondents will have to repeat the performance test due to failure.

 On average, EPA estimates 20 existing sources will be subject to the NSPS. No new sources will become subject to the standard 

over the three-year period of this ICR. EPA also estimates one existing facility will undergo either a reconstruction or a physical or 

operational change such that it will be required to submit initial notifications and conduct initial performance testing.

 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 20 percent of respondents will have to repeat the performance test due to failure.
