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 0982.10, 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, Metallic Mineral Processing Plants, were proposed on August 24, 1982,

promulgated on February 21, 1984, and amended on October 17, 2000. These regulations apply to 

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

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

packaging station, storage bin, enclosed storage area, truck loading and unloading station at the 

mill or concentrator, commencing construction, modification or reconstruction after the date of 

proposal. The NSPS does not apply to facilities located in underground mines, or to facilities 

performing the beneficiation of uranium ore at uranium ore processing plants, commencing 

construction, modification or reconstruction after the date of proposal. This information is being 

collected to assure compliance with 40 CFR part 60, subpart LL.

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 Agency (EPA) regional office.

Approximately 20 sources are currently subject to the regulation, and it is estimated that no 

additional sources per year will become subject to the regulation in the next three years. However, 

we estimate that one of the existing sources per year will engage in reconstruction or make a 

physical or operational change. This information was confirmed with the rule lead addressing this 

source category at the Office of Air Quality Planning and Standards (OAQPS).

There are approximately 20 metallic mineral processing plants in the United States, which 

are owned and operated by the metallic mineral processing industry (the “Affected Public”). None 
2

of the facilities in the United States are owned by state, local, tribal or the Federal government; all 

are privately, owned for-profit businesses. The burden to the “Affected Public” is listed in Table 1: 

Annual Industry Burden and Cost – NSPS for Metallic Mineral Processing Plants (40 CFR Part 60, 

Subpart LL) (Renewal). The Federal government burden associated with the review of reports 

submitted by the respondent is shown in Table 2: Average Annual EPA Burden – NSPS for 

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

In the development of the Information Collection Request (ICR), we addressed the Office 

of Management and Budget (OMB) “Terms of Clearance (TOC)” on the active ICR. The TOC 

are:

This collection of information is approved for 3 years. Before 

resubmission of this ICR, the Agency should update wage estimates, 

continuing to refer to most recently available data from Bureau of 

Labor Statistics. In addition, the agency should verify the number 

of respondent entities.

EPA has addressed each item of concern in the TOC. The updated labor rates and the 

number of respondents have been thoroughly checked, and all estimates have been updated.

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 
3

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 was 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. In addition, 

the collected information is 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 tests, 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 ensure that the pollution control devices are properly 

installed and operated, that leaks are being detected and repaired, and that the standards are being 

met. The performance test may also be observed.

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

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

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

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

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 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.
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 (76 FR 26900) on May 9, 2011. No comments were received on the burden 

published in the Federal Register.

3(c) Consultations

The Agency’s 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. The growth rate for the industry is 

based on our consultations with the Agency’s internal industry experts.

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. In developing this 

ICR, we contacted the United States Geological Survey (USGS) at (703) 648-5953, and the 

National Mining Association (NMA) at (202) 463-2600.

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.

These standards require the respondents to maintain all records, including reports and 

notifications for at least five years. This is consistent with the General Provisions as applied to the 

standards. EPA believes that the five-year records retention requirement is consistent with the part 

70 permit program and the five-year statute of limitations on which the permit program is based. 

The retention of records for five years allows the EPA to establish the compliance history of a 

source, any pattern of non-compliance, and to determine the appropriate level of enforcement 

action. EPA has found that the most flagrant violators have violations extending beyond the five 

years. In addition, EPA would be prevented from pursuing the violators due to the destruction or
5

nonexistence of essential records.

3(f) Confidentiality

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

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

Confidentiality of Business Information (CBI) (see 40 CFR 2; 41 FR 36902, September 1, 1976; 

amended by 43 FR 40000, September 8, 1978; 43 FR 42251, September 20, 1978; 44 FR 17674, 

March 23, 1979).

3(g) Sensitive Questions

The reporting or recordkeeping requirements in 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 for the 

respondents affected by the standards, which corresponds to The North American Industry

Classification System (NAICS) codes, are listed below for source category description.

Standard (40 CFR Part 63, Subpart LL) SIC Codes NAICS Codes

Iron Ore Mining 1001 21221

Copper Ore and Nickel Ore Mining 1021 212234

Lead Ore and Zinc Ore Mining 1031 212231

Gold Ore Mining 1041 212221

Silver Ore Mining 1044 212222

Copper Ore and Nickel Ore Mining 1061 212234

All Other Metal Ore Mining 1099 212299

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 NSPS for Metallic 

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

A source must make the following reports:
6

Notifications

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

Notification of actual startup 60.7(a)(3)

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

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

Initial performance test results 60.8(a)

Initial performance test 60.8(d)

A source must keep the following records:

Recordkeeping 

Startups, shutdowns, and malfunctions, periods where the continuous 

monitoring system is inoperative.

60.7(b)

Measurements of both the change in pressure of the gas stream across 

the scrubber and the scrubbing liquid flow rate.

60.385(b)

Records are required to be retained 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 not widely 

used. At this time, it is estimated that approximately 10 percent of the respondents use electronic 

reporting.

Respondent Activities

Read instructions.

Install, calibrate, maintain, and operate CMS for opacity, or for pressure drop and liquid supply 

pressure for wet scrubber

Perform initial performance test, Reference Method 9 test, 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.
7

Respondent Activities

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

Observe initial performance tests and repeat performance tests if necessary.

Review notifications and reports, including performance test reports, 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 operational. Performance 

test reports are used by the Agency to discern a source’s initial capability to comply with the 

emission standard, and to 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 OTIS which is operated and maintained 

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

retrieval of compliance data for approximately 125,000 industrial and government-owned 

facilities. EPA uses OTIS for tracking air pollution compliance and enforcement by local and state 

regulatory agencies, EPA regional offices, and EPA headquarters. EPA delegated Authorities can 

edit, store, retrieve, and analyze the data.
8

The records required by this regulation must be retained by the owner or 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 Table 1: Annual Industry Burden for 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. Wherever 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 2,306 (Total Labor Hours from Table 1). 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:
9

Managerial $119.36 ($56.84 + 110%) 

Technical $99.18 ($47.23 + 110%)

Clerical $49.35 ($23.50 + 110%)

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

2011, "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 costs are the 

ongoing costs to maintain the monitor and other costs, such as photocopying and postage.

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

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 

$10,380.
10

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) “2011 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 in Table 2: Average Annual EPA Burden, 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. It is estimated that no additional respondent 

per year will become subject to the standard. 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 number of Total Annual Responses is 44.

The total annual labor costs are $220,712. Details regarding these estimates may be found 

in Table 1: Annual Industry Burden and Cost – NSPS for Metallic Mineral Processing Plants (40 

CFR Part 60, Subpart LL) (Renewal).

6(e) Bottom Line Burden Hours 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, respectively, and summarized below. 

(i) Respondent Tally

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 52 hours per response.

The total annual capital/startup and operation and maintenance (O&M) costs to the 

regulated entity are $13,000.

(ii) The Agency Tally

The average annual Agency burden and cost over the next three years is estimated to be 

230 labor hours at a cost of $10,380. See Table 2: Annual Agency Burden and Cost: NSPS for 

Metallic Mineral processing Plants (40 CFR Part 63, Subpart LL) (Renewal).

6(f) Reasons for Change in Burden
12

There is no change in the labor hours to the respondents in this ICR compared to the 

previous ICR. After consulting the Office of Air Quality Planning and Standards (OAQPS) and 

trade associations, our data indicates that there are approximately twenty sources subject to the 

rule, with no additional new sources over the next three years. 

However, there is an increase in the estimated burden cost as currently identified in the 

OMB Inventory of Approved Burdens. The increase is not due to any program changes. The 

change in burden is due to the use of the most updated labor rates.

6(g) Burden Statement

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

estimated to average 52 hours per response. Burden means the total time, effort, or financial 

resources expended by persons to generate, maintain, retain, 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

Assumptions:

 a We have assumed that there are approximately 20 respondents that will become subject to the rule, with no additional new sources over the next three years. 

However, we have estimated that one existing source per year will engage in reconstruction or make a physical or operational change.

 b

This ICR uses the following labor rates: $119.36 per hour for Executive, Administrative, and Managerial labor; $99.18 per hour for Technical labor, and $49.35 

per hour for Clerical labor. These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 2011, Table 2. Civilian Workers, by 

Occupational and Industry groups. 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 it will take one hour for each respondent to read instructions.

d

 We have assumed that it will take 330 hours for each respondent to complete an initial performance test.

e

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

f

 We have assumed that it will take 2 hours for each respondent to complete report.

g

 We have assumed that it will take 8 hours, twice per year, for each respondent to write the scrubber malfunction report.

h We have assumed that each respondent will enter information on records of operating parameters 250 times per year.

i 

 We have assumed that each respondent will enter information once per year on records of startup, shutdown, and malfunction.
