ENVIRONMENTAL PROTECTION AGENCY

NSPS for Sewage Sludge Treatment Plants (40 CFR Part 60, Subpart O) (Renewal)

1. Identification of the Information Collection

1(a) Title of the Information Collection

NSPS for Sewage Sludge Treatment Plants (40 CFR Part 60, Subpart O) (Renewal), 

EPA ICR Number 1063.12, OMB Control Number 2060-0035

1(b) Short Characterization/Abstract

The New Source Performance Standards (NSPS) for the Sewage Sludge Treatment Plants

were: 1) promulgated on February 28, 1974; and 2) amended on October 6, 1975, November 10, 

1977, October 6, 1988, and October 17, 2000. These regulations apply to each incinerator which 

combusts wastes that contain more than 10 percent sewage sludge (dry basis) produced by 

municipal sewage treatment plants or each incinerator which charges more than 1000 kg (2205 

lb.) per day municipal sewage sludge (dry basis). New facilities include those that commenced 

construction, modification, or reconstruction after the date of proposal. These standards set 

emission limitation for particulate matter (PM). This information is being collected to assure 

compliance with 40 CFR part 60, subpart O.

In general, all NSPS standards require initial notifications, performance tests, and 

periodic reports by the owners/operators of the affected facilities. They are also required to 

maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the

operation of an affected facility, or any period during which the monitoring system is 

inoperative. These notifications, reports, and records are essential in determining compliance, 

and are required of all affected facilities subject to NSPS. 

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

measurements, and retain the file for at least two years following the date of such measurements, 

maintenance reports, and records. All reports are sent to the delegated state or local authority. 

In the event that there is no such delegated authority, the reports are sent directly to the U.S.

Environmental Protection Agency (EPA) regional office.

 Based on our consultations with industry representatives, there is an average of 2 

affected units (112 facilities with 218 units) at each plant site and that each plant site has only

one respondent (i.e., the owner/operator of the plant site).

Over the next three years, an average of 112 respondents per year will be subject to the 

standard, and an additional 0.4 respondents per year will become subject to the standard due to 

modification or reconstruction. This is based on the assumption that two existing facilities will 
2

be modified or reconstructed over the next five years (0.4 facility per year). 

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

without any “Terms of Clearance.”

All of the sewage sludge treatment plants are owned by state, local, or tribal 

governments. The “burden” to the “Affected Public” may be found below in Table 1: Annual 

Respondent Burden and Cost – NSPS for Sewage Sludge Treatment Plants (40 CFR Part 60, 

Subpart O) (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 – NSPS for Sewage Sludge Treatment Plants 

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

2. Need for and Use of the Collection

2(a) Need/Authority for the Collection

The EPA is charged under Section 111 of the Clean Air Act (CAA), as amended, to 

establish standards of performance for new stationary sources that reflect: 

. . . application of the best technological system of continuous 

emissions reduction which (taking into consideration the cost of 

achieving such emissions reduction, or any non-air quality health 

and environmental impact and energy requirements) the 

Administrator determines has been adequately demonstrated. 

Section 111(a)(l).

The Agency refers to this charge as selecting the best demonstrated technology (BDT). Section 

111 also requires that the Administrator review and, if appropriate, revise such standards every

four years. In addition, section 114(a) states that the Administrator may require any 

owner/operator subject to any requirement of this Act to: 

(A) Establish and maintain such records; (B) make such reports; 

(C) install, use, and maintain such monitoring equipment, and use 

such audit procedures, or methods; (D) sample such emissions (in 

accordance with such procedures or methods, at such locations, at 

such intervals, during such periods, and in such manner as the 

Administrator shall prescribe); (E) keep records on control 

equipment parameters, production variables or other indirect data 

when direct monitoring of emissions is impractical; (F) submit 

compliance certifications in accordance with Section 114(a)(3); 

and (G) provide such other information as the Administrator may

reasonably require.
3

In the Administrator's judgment, particulate matter emissions from sewage sludge 

treatment plants either cause or contribute to air pollution that may reasonably be anticipated to 

endanger public health and/or welfare. Therefore, the NSPS were promulgated for this source 

category at 40 CFR part 60, subpart O.

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.

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, leaks are being detected and repaired, and the standard 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 60, subpart O.

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 (78 FR 33409) on June 4, 2013. No comments were received on the 
4

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 EPA's Office of Compliance. OTIS is EPA’s 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 and the standard 

has been previously reviewed to determine the minimum information needed for compliance 

purposes. In developing this ICR, we contacted: 1) the National Association of Clean Waters, 

at 202-833-2672; and 2) the Water Environment Federation, at 703-684-2400.

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 (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 sewage sludge 

treatment plants. The United States Standard Industrial Classification (SIC) code for the

60.153(e)

Maintain records 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 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 for pressure drop and liquid 

supply pressure for wet scrubber.

Perform initial performance test, Reference Method 5 and 9 test, and repeat tests if necessary.
8

Respondent Activities

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.

Adjust existing ways to comply with any previously applicable instructions and requirements.

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

Transmit, or otherwise disclose the information.

Currently sources are using monitoring and reporting equipment that provide parameter 

data in an automated way (e.g., continuous parameter monitoring system). Although personnel 

at the source still need to evaluate the data, this type of monitoring equipment has significantly 

reduced the burden associated with monitoring and recordkeeping. 

5. The Information Collected: Agency Activities, Collection Methodology, and 

Information Management

5(a) Agency Activities 

EPA conducts the following activities in connection with the acquisition, analysis, 

storage, and distribution of the required information.

Agency Activities

Observe initial performance tests and repeat performance test 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).
9

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 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 these regulations must be retained by the owner/operator for two 

years.

5(c) Small Entity Flexibility

There are no small entities (i.e., small businesses) affected by this regulation.

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 – NSPS for Sewage Sludge 

Treatment Plants (40 CFR Part 60, Subpart O) (Renewal).

6. Estimating the Burden and Cost of the Collection

Table 1 below 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 collection are mandatory.

Wherever appropriate, specific tasks and major assumptions have been identified. Responses 

to this information 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.
10

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 12,464 hours (Total Labor Hours from 

Table 1 below). 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: 

Managerial $123.04 ($58.59 + 110%) 

Technical $101.22 ($48.20 + 110%)

Clerical $51.18 ($24.37 + 110%)

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

2013, “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 types 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 regulations. The annual operation and maintenance costs are the 

ongoing costs to maintain the monitor(s) and other costs such as photocopying and postage.

11

the above table. 

The total operation and maintenance (O&M) costs for this ICR are $3,920,000. 

This is the total of column G. 

The average annual cost for both capital/startup and operation and maintenance costs 

to industry over the next three years of the ICR is estimated to be $3,960,000. 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 

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 

$94,499. 

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), 2013 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 Sewage 

Sludge Treatment Plants (40 CFR Part 60, Subpart O) (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

112 existing respondents will be subject to the standards. It is estimated that an additional 0.4

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

in the table below, is 112 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 $1,219,185. Details regarding these estimates may be 
13

found below in Table 1: Annual Respondent Burden and Cost – NSPS for Sewage Sludge 

Treatment Plants (40 CFR Part 60, Subpart O) (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 12,464 hours at a cost of $1,219,185. Details regarding 

these estimates may be found below in Table 1: Annual Respondent Burden and Cost – NSPS for 

Sewage Sludge Treatment Plants (40 CFR Part 60, Subpart O) (Renewal). 

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

information is estimated to average 55 hours per response.

The total annual capital/startup and O&M costs to the regulated entity are $3,960,000. 

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 

2,097 labor hours at a cost of $94,499. See Table 2 below: Average Annual EPA Burden and 

Cost – NSPS for Sewage Sludge Treatment Plants (40 CFR Part 60, Subpart O) (Renewal).

6(f) Reasons for Change in Burden

There is no change in labor hours in this ICR compared to the most recently approved 

ICR. This is due to two considerations. First, the regulations have not changed over the past 

three years and are not anticipated to change over the next three years. Secondly, the growth rate 

for the industry is very low, so there is no significant change in the overall burden. However, 

there is a slight increase in the respondent labor costs due to the use of updated labor rates. 

6(g) Burden Statement

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

is estimated to average 55 hours per response (rounded). “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 
14

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

TOTAL LABOR BURDEN AND COST 

(rounded) 12,464 $1,219,185

Assumptions:

a This ICR uses the following labor rates: $123.04 per hour for Executive, Administrative, and Managerial labor; $101.22 per hour for Technical labor, and 

$51.18 per hour for Clerical labor. These rates are the United States Department of Labor, Bureau of Labor Statistics, March 2013, “Table 2. Civilian Workers, 

by occupational and industry group.” The rates are from column 1, “Total compensation.” The rate has been increased by 110 percent to account for the 

benefit packages available to those employed by private industry.

b

 Assume that there will be 1.2 new, modified, or reconstructed units constructed over the next three years or 0.4 source per year.

c

 Assume that this is a one-time-only cost.

d

 Assume that 20 percent would have to repeat the performance testing due to failure.

e

 Assume that 0.4 facility will have a physical or operational change.

f Assume that it will take 40 hours to write semiannual reports.

g

 Assume that there are 112 facilities subject to this rule.

h

 Assume that it will take eight hours per year to record daily gathering of monitoring data (which have been automatically recorded).

i Assume that it will take 80 hours per year to record performance test data.

TOTAL LABOR BURDEN and COST (rounded) 2,097 $94,499.

Assumptions:

a

 This cost is based on the following hourly labor rates times a 1.6 benefits multiplication factor to account for government overhead expenses: $62.27 for 

Managerial (GS-13, Step 5, $38.92 x 1.6), $46.22 for Technical (GS-12, Step 1, $28.88 x 1.6) and $25.01 Clerical (GS-6, Step 3, $15.63 x 1.6). These rates are 

from the Office of Personnel Management (OPM) "2013 General Schedule" which excludes locality rates of pay.

b

 Assume that there will be 0.4 new, modified or reconstructed unit constructed per year over the next three years.

c

 Assume that this is a one-time-only cost.

d

 Assume that 20 percent would have to repeat the performance testing due to failure.

e

 Assume that 0.4 source will have a physical or operational change.

f Assume that it will take eight hours to review semiannual reports.

g

 Assume that there are 112 sources subject to this rule.
