NESHAP for Mercury (40 CFR Part 61, Subpart E) (Renewal)

1. Identification of the Information Collection

1(a) Title of the Information Collection

NESHAP for Mercury (40 CFR Part 63, Subpart S) (Renewal), EPA ICR Number 0113.14, OMB Control Number 2060-0097.

1(b) Short Characterization/Abstract

The Emission Standards for Hazardous Air Pollutants (NESHAP) for Mercury (40 CFR Part 61, Subpart E) were proposed on December 7, 1971, promulgated on April 6, 1973, and amended on October 14, 1975, March 19, 1987, October 17, 2000, and February 27, 2014. These regulations apply to existing facilities and new facilities which process mercury ore to recover mercury, use mercury chlor-alkali cells to produce chlorine gas and alkali metal hydroxide, and incinerate or dry wastewater treatment plant sludge. New facilities include those that commenced construction, modification or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 61, Subpart E.

In general, all NESHAP 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 NESHAP.

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 required to be submitted electronically are submitted through the EPA's Central Data Exchange (CDX), using the Compliance and Emissions Data Reporting Interface (CEDRI), where the delegated state or local authority can review them. In the event that there is no such delegated authority, the EPA regional office can review them. All other 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 EPA regional offices. The use of the term "Designated Administrator" throughout this document refers to the U.S. EPA or a delegated authority such as a state agency. The term "Administrator" alone refers to the U.S. EPA Administrator. 

The “Affected Public” includes mercury ore processing facilities, mercury cell chlor-alkali plants, sludge incineration plants, and sludge drying plants. The burden to the “Affected Public” may be found in Table 1: Annual Respondent Burden and Cost – NESHAP for Mercury (40 CFR Part 61, Subpart E) (Renewal). The “Federal Government” burden is attributed entirely to work performed by federal employees or government contractors and refer to Table 2: Average Annual EPA Burden and Cost – NESHAP for Mercury (40 CFR Part 61, Subpart E) (Renewal). There are approximately 101 facilities, which are owned and operated by industry. None of the 101 facilities in the United States are owned by state, local, tribal or the Federal government. They are all owned and operated by privately-owned, for-profit businesses. We assume that they will all respond.

Based on our consultations with industry representatives, there are an average of one affected facility at each plant site and each plant site has only one respondent (i.e., the owner/operator of the plant site).

Over the next three years, approximately 101 respondents (100 wastewater sludge incineration and drying plants and 1 cell chlor-alkali plant) per year will be subject to the standard, and no additional 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.”

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, mercury emissions from mercury ore processing facilities, mercury cell chlor-alkali plants, sludge incineration plants, and sludge drying plants cause or contribute to air pollution that may reasonably be anticipated to endanger public health or welfare. Therefore, the NESHAP were promulgated for this source category at 40 CFR Part 61, Subpart E.

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 capability to comply with the emission standards. Continuous emission monitors are used to ensure compliance with the 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 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, leaks are being detected and repaired, and the standards are being met. The performance test may also be observed.

The required annual and 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

The requested recordkeeping and reporting are required under 40 CFR Part 61 Subpart E.

3(a) Nonduplication

For reports required to be submitted electronically, the information is sent through the EPA's CDX, using CEDRI, where the appropriate EPA regional office can review it, as well as state and local agencies that have been delegated authority. If a state or local agency has adopted under its own authority its own standards for reporting or data collection, adherence to those non-Federal requirements does not constitute duplication. 

For all other reports, 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 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 (86 FR 19256) on April 13, 2021. No comments were received on the burden published in the Federal Register for this renewal.

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 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. Approximately 101 respondents will be subject to the standard 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 the standard as it was being developed and the standard has been previously reviewed to determine the minimum information needed for compliance purposes. In developing this ICR, we contacted both the California Association of Sanitation Agencies, at (916) 446-0388 and Frankfort Municipal Utilities at (765) 659-4741.

It is our policy to respond after a thorough review of comments received since the last ICR renewal as well as those submitted in response to the first Federal Register notice. In this case, no comments were received.

3(d) Effects of Less Frequent Collection

Less frequent information collection would decrease the margin of assurance that facilities are continuing to meet the standards. Requirements for information gathering and recordkeeping are useful techniques to ensure that good operation and maintenance practices are applied and emission limitations are met. If the information required by these standards was collected less frequently, the proper operation and maintenance of control equipment and the possibility of detecting violations would be less likely.

3(e) General Guidelines

These reporting or recordkeeping requirements do not violate any of the regulations promulgated by OMB under 5 CFR Part 1320, Section 1320.5.

3(f) Confidentiality

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

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

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

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 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 standard and note the operating conditions under which compliance was achieved. Data and records maintained by the respondents are tabulated and published for use in compliance and enforcement programs. The semiannual reports are used for problem identification, as a check on source operation and maintenance, and for compliance determinations.

Information contained in the reports is 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, except that records of monitoring device certification must be retained for the life of the device.

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 these regulations. 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 at the end of this document in Table 1: Annual Respondent Burden and Cost – NESHAP for Mercury (40 CFR Part 61, Subpart E) (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 17,200 (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 NESHAP 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 $153.55 ($73.12 + 110%)

Technical $122.20 ($58.19 + 110%)

Clerical $61.51 ($29.29 + 110%)

These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 2021, “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 only costs to the regulated industry resulting from information collection activities required by the subject standard(s) are labor costs. There are no capital/startup or operation and maintenance costs.

(iii) Capital/Startup vs. Operation and Maintenance (O&M) Costs

The only type of industry costs associated with the information collection activity in the regulations are labor costs. There are no capital/startup or operation and maintenance 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 $24,800.

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

Managerial $69.04 (GS-13, Step 5, $43.15 + 60%)

Technical $51.23 (GS-12, Step 1, $32.02 + 60%)

Clerical $27.73 (GS-6, Step 3, $17.33 + 60%)

These rates are from the Office of Personnel Management (OPM), 2021 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 at the end of this document in Table 2: Average Annual EPA Burden and Cost – NESHAP for Mercury (40 CFR Part 61, Subpart E) (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 101 existing respondents will be subject to the standard. It is estimated that no additional respondents per year will become subject. The overall average number of respondents, as shown in the table below, is 101 per year.

The number of respondents is calculated using the following table that addresses the three years covered by this ICR.

Number of Respondents
	Respondents That Submit Reports		Respondents That Do Not Submit Any Reports
Year	(A) Number of New Respondents 1	(B) Number of Existing Respondents	(C) Number of Existing Respondents that keep records but do not submit reports	(D) Number of Existing Respondents That Are Also New Respondents	(E) Number of Respondents (E=A+B+C-D)
1	0	101	0	0	101
2	0	101	0	0	101
3	0	101	0	0	101
Average	0	101	0	0	101

¹ New respondents include sources with constructed, reconstructed and modified affected facilities.

Column D is subtracted to avoid double-counting respondents. As shown above, the average Number of Respondents over the three-year period of this ICR is 101.

The total number of annual responses per year is calculated using the following table:

Total Annual Responses
(A) Information Collection Activity	(B) Number of Respondents	(C) Number of Responses	(D) Number of Existing Respondents That Keep Records But Do Not Submit Reports	(E) Total Annual Responses E=(BxC)+D
Notification of construction/reconstruction	0	1	0	0
Notification of initial startup	0	1	0	0
Notification of actual startup	0	1	0	0
Notification of initial performance test	0	1	0	0
Report of annual emission monitoring	100	1	0	100
Submit semiannual report	1	2	0	2
Notification of parameter excursions	1	2	0	2
			Total	104

The number of Total Annual Responses is 104.

The total annual labor costs are $2,030,000. Details regarding these estimates may be found at the end of this document in Table 1: Annual Respondent Burden and Cost – NESHAP for Mercury (40 CFR Part 61, Subpart E) (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 at the end of this document, respectively, and summarized below.

(i) Respondent Tally

The total annual labor hours are 17,200. Details regarding these estimates may be found in Table 1: Annual Respondent Burden and Cost – NESHAP for Mercury (40 CFR Part 61, Subpart E) (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 information is estimated to average 165 hours per response.

There is no annual capital/startup and O&M costs to the regulated entity.

(ii) The Agency Tally

The average annual Agency burden and cost over next three years is estimated to be 497 labor hours at a cost of $24,800. See Table 2: Average Annual EPA Burden and Cost – NESHAP for Mercury (40 CFR Part 61, Subpart E) (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 an adjustment decrease in the total estimated burden as currently identified in the OMB Inventory of Approved Burdens. This decrease is not due to any program changes. The adjustment decrease in burden from the most recently approved ICR is due to a decrease in the number of sources. Consultations with the Agency’s internal industry experts have shown that a number of cell chlor-alkali plants have shut down since the previous ICR renewal, leading to a decrease in respondent labor hours and the number of responses. There are no capital or operation and maintenance costs associated with this ICR. The overall result is a decrease in burden.

6(g) Burden Statement

The annual public reporting and recordkeeping burden for this collection of information is estimated to average 165 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.

a We have assumed that there are approximately 101 (100 wastewater sludge incineration and drying plants and 1 cell chlor-alkali plant) existing sources currently subject to this rule. There will be no additional new source that will become subject to the rule over the three-year period of this ICR.
b This ICR uses the following labor rates: $153.55 per hour for Executive, Administrative, and Managerial labor; $122.20 per hour for Technical labor, and $61.51 per hour for Clerical labor. These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 2021 “Table 2. Civilian Workers, by occupational and industry group.” The rates are from column 1, “Total compensation.” The rates have been increased by 110 percent to account for the benefit packages available to those employed by private industry.
c We have assumed that it will take 1 hour for existing respondents to refamiliarize themselves with rule requirements.
d We have assumed that it will take each new respondent 24 hours to complete initial performance test. Since there are no new respondents estimated, this requirement does not apply.
e We have assumed that 20 percent of new respondents will repeat the performance test due to failure. Since there are no new respondents estimated, this requirement does not apply.
f We have assumed that each new respondent will take two hours to write notification reports on construction/reconstruction. Since there are no new respondents estimated, this requirement does not apply.
g We have assumed that it will take each new respondent two hours each to write notification reports on initial startup and actual startup. Since there are no new respondents estimated, this requirement does not apply.
h We have assumed that 100 of the existing respondents will take 12 hours to write reports on the annual emission tests.
i We have assumed that one of the existing respondents will each have to submit semiannual reports.
j We have assumed that one of the existing respondents will write notification reports on parameter excursions two times per year.
k We have assumed that all respondents will record operating parameters 365 days per year.
l We have assumed that one respondent will each have to record mercury leaks and monitored parameters.
m We have assumed that one respondent will each take eight hours to compile data for semiannual reports.
n We have assumed that one respondent will have to maintain data on mercury leaks and monitored parameters 52 times per year.
o We have assumed that 50 percent of the respondents will each take 1.5 hours to record information of startup, shutdown, and malfunctions.
p Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.

a We have assumed that there are approximately 101 (100 wastewater sludge incineration and drying plants and 1 cell chlor-alkali plant) existing sources currently subject to this rule. There will be no additional new source that will become subject to the rule over the three-year period of this ICR.
b This cost is based on the following labor rates which incorporates a 1.6 benefits multiplication factor to account for government overhead expenses: $69.04 for Managerial (GS-13, Step 5), $51.23 for Technical (GS-12, Step 1), and $27.73 Clerical (GS-6, Step 3). These rates are from the Office of Personnel Management (OPM) “2021 General Schedule” which excludes locality rates of pay.
c We have assumed that the Agency will take 24 hours to participate in the performance tests. It is assumed that all initial performance tests have been completed by existing respondents. Since there are no new respondents estimated, this requirement does not apply.
d We have assumed that 20 percent of new respondents will have to repeat the performance tests due to failure. Since there are no new respondents estimated, this requirement does not apply.
e We have assumed that it will take 0.5 hours for the Agency to review notification reports for each respondent. Since there are no new respondents estimated, this requirement does not apply.
f We have assumed that it will take 8 hours for the Agency to review test results for each respondent. Since there are no new respondents estimated, this requirement does not apply.
g We have assumed that one of the existing respondents will each have to submit semiannual reports, and the Agency will take eight hours two times per year to review each report.
h We have assumed that one respondents will each have to record mercury leaks and monitored parameters, and the Agency will take eight hours each to review each notification.
i Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.
