ENVIRONMENTAL PROTECTION AGENCY

NESHAP for Primary Magnesium Refining (40 CFR Part 63, Subpart TTTTT) (Renewal)

1. Identification of the Information Collection

1(a) Title of the Information Collection

NESHAP for Primary Magnesium Refining (40 CFR Part 63, Subpart TTTTT) (Renewal), 

EPA ICR Number 2098.07, OMB Control Number 2060-0536. 

1(b) Short Characterization/Abstract

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Primary 

Magnesium Refining (40 CFR Part 63, Subpart TTTTT) were proposed on January 22, 2003, 

promulgated on October 10, 2003, and amended on April 20, 2006. These regulations apply to 

existing facilities and new facilities that perform primary magnesium refining where the total 

hazardous air pollutants (HAPs) emitted are greater than, or equal to, 10 tons per year for each 

HAP, or where the total HAPs emitted are greater than, or equal to, 25 tons per year of any 

combination of HAPs. New facilities include those that commenced construction or 

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

compliance with 40 CFR Part 63, Subpart TTTTT.

In general, all NESHAP standards require initial notification reports, 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 NESHAP.

Any owner/operator subject to the provisions of this part shall maintain a file containing 

these documents, and retain the file for at least five years following the generation date of such 

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 U.S.

Environmental Protection Agency (EPA) regional office.

The Affected Public is a single primary magnesium refining facility that is a privatelyowned, for-profit business. The “burden” to the Affected Public may be found below in Table 1: 

Annual Respondent Burden and Cost – NESHAP for Primary Magnesium Refining (40 CFR Part 

63, Subpart TTTTT) (Renewal). The “burden” to the Federal Government is attributed entirely to 

work performed by either Federal employees or government contractors, and may be found 

below in Table 2: Average Annual EPA Burden and Cost – NESHAP for Primary Magnesium 

Refining (40 CFR Part 63, Subpart TTTTT) (Renewal).

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 
2

owner/operator of the plant site).

Over the next three years, approximately one respondents per year will be subject to 

these standards, and no additional respondents per year will become subject to these same 

standards.

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 112 of the Clean Air Act, as amended, to establish 

standards of performance for each category or subcategory of major sources and area sources of 

hazardous air pollutants. These standards are applicable to new or existing sources of hazardous 

air pollutants and shall require the maximum degree of emission reduction. 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, HAP emissions from primary magnesium refining either 

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

and/or welfare. Therefore, the NESHAP were promulgated for this source category at 40 CFR 

Part 63, Subpart TTTTT.

2(b) Practical Utility/Users of the Data

The recordkeeping and reporting requirements in these standards 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.

Performance tests are required in order to determine an affected facility’s initial 
3

capability to comply with the emission standards. Continuous emission monitors are used to 

ensure compliance with these standards 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 these 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, leaks are being detected and repaired, and the standards are 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 63, Subpart

TTTTT.

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, duplication does 

not exist.

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 (80 FR 32116) on June 5, 2015. 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 these standards, is the Integrated Compliance Information System (ICIS). ICIS is 

EPA’s database for the collection, maintenance, and retrieval of compliance data for industrial 

and government-owned facilities. The growth rate for the industry is based on our consultations 

with the Agency’s internal industry experts. Only a single respondent will be subject to these
4

standards over the three-year period covered by this ICR.

Industry trade association(s) and other interested parties were provided an opportunity to 

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

standards have been reviewed previously to determine the minimum information needed for 

compliance purposes. In developing this ICR, we contacted our internal industry experts in EPA 

OAQPS, and the US Magnesium LLC, at (801) 532-2043.

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.

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 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 five 

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

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).
5

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 primary magnesium 

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

affected by the standards is SIC 3339, which corresponds to the North American Industry 

Classification System (NAICS) code 331410 for Primary Smelting and Refining of Nonferrous 

Metal (except copper and aluminum).

4(b) Information Requested

(i) Data Items

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

Primary Magnesium Refining (40 CFR Part 63, Subpart TTTTT).

A source must make the following reports:

Notifications

Initial notification 63.9930(a), 63.9(b)

Notification of compliance status 63.9930(a), 63.9(h)

Notification of construction or reconstruction 63.9930(a), 63.5(b)(4), 

63.9(b)(5)

Notification of actual startup 63.9930(a), 63.9(b)(4)(v), 

63.9(b)(5)(ii)

Documentation of performance tests and opacity observations 63.9932(a)(3), 

63.10(b)(2)(viii)

Records required to demonstrate continuous compliance 63.9932(b)

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.

(ii) Respondent Activities

Respondent Activities

Familiarization with the regulatory requirements.

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

rate for wet scrubber.

providing information.

Train personnel to be able to respond to a collection of information.
7

Respondent Activities

Transmit, or otherwise disclose the information.

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, 

startup, shutdown, malfunction plan, and quality control plan for CMS required to be 

submitted by industry.

Audit facility records.

Input, analyze, and maintain data in the Enforcement and Compliance History Online (ECHO) 

and ICIS.

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 standards. 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 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.
8

The records required by this regulation must be retained by the owner/operator for five

years.

5(c) Small Entity Flexibility

The majority of respondents are 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 below in Table 1: Annual Respondent Burden and Cost – NESHAP for Primary 

Magnesium Refining (40 CFR Part 63, Subpart TTTTT) (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 611 (Total Labor Hours from Table 1 below).

These hours are based on Agency studies and background documents from the development of 

the regulations, Agency knowledge and experience with the NESHAP program, the previouslyapproved ICR, and any comments received.

6(b) Estimating Respondent Costs

(i) Estimating Labor Costs

This ICR uses the following labor rates: 
9

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 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.

The total capital/startup costs for this ICR is $0. This is the total of column D in the 

above table. 

The total operation and maintenance (O&M) costs for this ICR are $1,200. 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 $1,200. These are recordkeeping 

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 
10

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 

$8,090.

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 – NESHAP for Primary 

Magnesium Refining (40 CFR Part 63, Subpart TTTTT) (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 

one existing respondent will be subject to these standards. It is estimated that no additional 

respondents per year will become subject to these same standards. The overall average number 

of respondents, as shown in the table below, is one per year.

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

years covered by this ICR:

Total 4.13

The number of Total Annual Responses is 4 (rounded).

The total annual labor costs are $61,500. Details regarding these estimates may be found 

below in Table 1: Annual Respondent Burden and Cost – NESHAP for Primary Magnesium 

Refining (40 CFR Part 63, Subpart TTTTT) (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 below in Tables 1 and 2, respectively, and summarized below.

(i) Respondent Tally

The total annual labor hours are 611 hours. Details regarding these estimates may be 

found below in Table 1: Annual Respondent Burden and Cost – NESHAP for Primary 

Magnesium Refining (40 CFR Part 63, Subpart TTTTT) (Renewal).

We assume that burdens for managerial tasks take 5% of the time required for technical 

tasks because the typical tasks for managers are to review and approve reports. Clerical burdens 

are assumed to take 10% of the time required for technical tasks because the typical duties of 

clerical staff are to proofread the reports, make copies and maintain records.

Furthermore, the annual public reporting and recordkeeping burden for this collection of 
12

information is estimated to average 153 hours per response.

The total annual capital/startup and O&M costs to the regulated entity are $1,200. 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 178

labor hours at a cost of $8,090. See below in Table 2: Average Annual EPA Burden and Cost –

NESHAP for Primary Magnesium Refining (40 CFR Part 63, Subpart TTTTT) (Renewal).

We assume that burdens for managerial tasks take 5% of the time required for technical 

tasks because the typical tasks for managers are to review and approve reports. Clerical burdens 

are assumed to take 10% of the time required for technical tasks because the typical duties of 

clerical staff are to proofread the reports, make copies and maintain records.

6(f) Reasons for Change in Burden

There is no change in burden hours in this ICR from the previous ICR because the 

regulations has not changed, and are not expected to change, in the next three years. There is, 

however, a small adjustment increase in the estimated labor costs as due to an update in labor 

rates. 

6(g) Burden Statement

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

is estimated to average 153 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 

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

Grand Total (rounded) h $62,700 

Assumptions:

a

 We have assumed that there are approximately one respondents subject to the rule, with no new sources expected over the next three-years of this ICR. b

 This ICR uses the following labor rates: Technical $103.97 ($49.51 + 110%); Managerial $129.93 ($61.87+ 110%); and 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. This ICR assumes that Managerial hours are 5 percent of Technical hours, and Clerical hours are 10 percent of Technical hours. c

 We have assumed that performance test will be repeated once in three years.

d

 We assume that this includes Method 23 test. e

 We assumed that it will take respondent ten hours two times per year to complete semiannual report.

f

 This includes inspection of unpaved areas.

g

 We assume that it will take 1 hour once per month to retrieve records/reports. h

 Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.

Total Annual Burden and Costs 

(rounded) f 178 $8,090 

Assumption:

a

 We have assumed that there are approximately one respondents subject to the rule, with no new sources expected over the next three-years of this ICR. b

 This cost is based on the average hourly labor rate as follows: Technical $46.67 (GS-12, Step 1, $29.17 + 60%); Managerial $62.90 (GS-13, Step 5, $39.31 + 

60%); and Clerical $25.25 (GS-6, Step 3, $15.78 + 60%). This ICR assumes that Managerial hours are 5 percent of Technical hours, and Clerical hours are 10

percent of Technical hours. These rates are from the 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.
