SUPPORTING STATEMENT

ENVIRONMENTAL PROTECTION AGENCY

NSPS for Industrial/Commercial/Institutional Steam Generating Units (40 CFR Part 60, 

Subpart Db) (Renewal)

1. Identification of the Information Collection

1(a) Title of the Information Collection

NSPS for Industrial/Commercial/Institutional Steam Generating Units (40 CFR Part 60, Subpart 

Db) (Renewal), EPA ICR Number 1088.13, OMB Control Number 2060-0072. 

1(b) Short Characterization/Abstract

The New Source Performance Standards (NSPS) for Industrial/Commercial/Institutional 

Steam Generating Units were proposed on June 19, 1986, promulgated on December 16, 1987, 

and amended on February 27, 2006 (71 FR 9865), June 13, 2007 (72 FR 32710), January 28, 

2009 (74 FR 5072), and February 16, 2012 (77 FR 9303). The most-recent amendment made 

both revisions to the performance standards and corrections to existing provisions. The 

revisions did not result in any changes to either the reporting or record keeping requirements. 

These regulations apply to industrial/commercial/institutional steam generating units (boilers) 

that commenced construction, modification, or reconstruction after June 19, 1984, and have a 

heat input capacity from fuels combusted in the unit of greater than 29 megawatts (MW) (100 

million British thermal units per hour (MMBtu/hr)). This information is being collected to 

assure compliance with 40 CFR part 60, subpart Db.

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.

Over the next three years, an average of 1,727 respondents per year will be subject to the 

standard, and 45 additional respondents per year will become subject to the standard. The 

number of respondents is based on the 2003 ICR renewal, which estimates 1,322 existing 

facilities subject to subpart Db in 2003. The growth rate is based on an October 2002 economic 

analysis performed for the Industrial Boiler Maximum Achievable Control Technology

rulemaking, which estimated that 134 industrial, commercial, and institutional boilers would 

become subject to NSPS subpart Db over the next three years (or 45 per year). To account for 
2

facilities constructed since 2003, this ICR adds 405 facilities (45 times 9 years) to the 2003 ICR 

estimate of 1,322.

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

without any Terms of Clearance.

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

Burden and Cost – NSPS for Industrial/Commercial/Institutional Steam Generating Units (40 

CFR Part 60, Subpart Db) (Renewal). The burden to the “Federal Government” burden 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 

Industrial/Commercial/Institutional Steam Generating Units (40 CFR Part 60, Subpart Db) 

(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); 
3

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

reasonably require.

In the Administrator's judgment, sulfur dioxide (SO2), particulate matter (PM), and 

nitrogen oxides (NOx) emissions from industrial/commercial/institutional steam generating units

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

or welfare. Therefore, the NSPS were promulgated for this source category at 40 CFR part 60,

subpart Db.

2(b) Practical Utility/Users of the Data

The recordkeeping and reporting requirements in the standard ensure compliance 

with the applicable regulations which where 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. 

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 and the standard are being met. The performance test may also be 

observed.

The required quarterly or 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 

Db.

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 (77 FR 47631) on August 9, 2012. 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. 

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

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

improve the language in the standards to make it easier to comply. In developing this ICR, 

EPA contacted: 1) the Council of Industrial Boiler Owners, at (540) 349-9043; and 2) the 

American Boiler Manufacturers Association, at (703) 356-7172.

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 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 
5

beyond the 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).

3(g) Sensitive Questions

The reporting or recordkeeping requirements in the standard do not include sensitive 

questions.

4. The Respondents and the Information Requested

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 20 percent of the respondents use 

electronic reporting.

(ii) Respondent Activities

Respondent Activities

Read instructions.

Install, calibrate, maintain, certify, and operate continuous emission monitoring systems 

(CEMS) for NOx, SO2, and opacity or alternative monitoring methods (e.g., CO CEMS in 

place of using a continuous opacity monitoring system (COMS).

Perform initial performance test.

Write the notifications and reports listed above.
8

Respondent Activities

Enter information required to be recorded above.

Submit the required reports developing, acquiring, installing, and utilizing technology and 

systems for the purpose of collecting, validating, and verifying information.

Develop, acquire, install, and utilize technology and systems for the purpose of processing and 

maintaining information.

Develop, acquire, install, and utilize technology and systems for the purpose of disclosing and 

providing information.

Adjust the existing ways to comply with any previously applicable instructions and 

requirements.

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

Transmit, or otherwise disclose the information.

Currently sources are using monitoring and reporting equipment that provide parameter 

data in an automated way e.g., continuous parameter monitoring 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

Review notifications and reports, including performance test reports, and excess emissions 

reports, required to be submitted by industry.

Audit facility records.

Input, analyze, and maintain data in the Online Tracking Information System (OTIS).

5(b) Collection Methodology and Management

Following notification of startup, the reviewing authority could inspect the source to 
9

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. 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 this regulation must be retained by the owner/operator for two

years.

5(c) Small Entity Flexibility

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

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

development of the regulation. According to the “Regulatory Impact Analysis for the Final 

Mercury and Air Toxics Standards,” which was conducted for the 2012 NSPS amendment, EPA 

identified 82 potentially affected small entities. EPA has taken steps to minimize the significant 

economic impact on small entities. Small entities that do not own at least one generating unit 

with a capacity greater than 29 megawatts are not subject to the rule. According to EPA's initial 

regulatory flexibility analysis, this eliminates the burden for 26 small entities. For larger units 

affected by the proposed rule, EPA considered a number of comments received both during the 

Small Business Advocacy Review Panel and the public comment period, and has revised the 

final rule to greatly simplify continuous compliance requirements and decrease the frequency of 

periodic testing. EPA believes the revision will make compliance less onerous for all regulated 

units, including those owned by small entities.

5(d) Collection Schedule

The specific frequency for each information collection activity within this request is 

shown in below Table 1: NSPS for Industrial/Commercial/Institutional Steam Generating Units 

(40 CFR Part 60, Subpart Db) (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 
10

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 1,607,368 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 $121.44 ($57.83+ 110%) 

Technical $100.23 ($47.73 + 110%)

Clerical $50.51 ($24.05 + 110%)

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

2012, “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 onetime 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 are $9,000,000. This is the total of column D 

in the above table. 

The total operation and maintenance (O&M) costs for this ICR are $25,905,000. 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 $34,905,000. 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 

$58,404,760. 

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), 2012 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 

Industrial/Commercial/Institutional Steam Generating Units (40 CFR Part 60, Subpart Db) 

(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

1,682 existing respondents will be subject to the standard. It is estimated that an additional 45 

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

in the table below, is 1,727 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 $155,639,313. Details regarding these estimates may be 

found below in Table 1. Annual Respondent Burden and Cost – NSPS for 

Industrial/Commercial/Institutional Steam Generating Units (40 CFR Part 60, Subpart Db) 

(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, respectively, and summarized below. 

(i) Respondent Tally

The total annual labor hours are 1,607,368 at a cost of $155,639,313. Details regarding 

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

Industrial/Commercial/Institutional Steam Generating Units (40 CFR Part 60, Subpart Db) 

(Renewal). 

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

information is estimated to average 388 hours per response.

The total annual capital/startup and O&M costs to the regulated entity are $34,905,000. 

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 

1,296,018 labor hours at a cost of $58,404,760. See below Table 2: Average Annual EPA 

Burden and Cost – NSPS for Industrial/Commercial/Institutional Steam Generating Units (40 

CFR Part 60, Subpart Db) (Renewal).

6(f) Reasons for Change in Burden

There is an adjustment increase in the total estimated burden as currently identified in 

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

The estimated number of respondents has been adjusted to account for industry growth that has 

occurred since the most recent ICR was approved, and to correct an inconsistency in the previous 

ICR estimate. Specifically, this ICR corrects the estimated number of respondents to be 

consistent with the supporting rationale. Both adjustments resulted in an increased number of 

existing sources and associated respondent and Agency labor hours. Also, this ICR makes 

adjustments to respondent and Agency labor hours in order to make the estimation methodology

consistent with that of other ICRs. 

The previous ICR assumed that the per-respondent labor hours for each burden activity

accounted for all technical, managerial, and clerical hours. This ICR assumes that labor hours 
14

account for technical hours only, and that clerical and managerial hours require an additional 

10 and 5 percent of technical hours, respectively. Additionally, this ICR calculates burden 

costs using the most recent labor rates. 

There is an increase in respondent O&M costs, as calculated in section 6(b)(iii), 

compared to the costs in the previous ICR. This increase is also due to industry growth, and 

reflects O&M costs that will be incurred by both existing facilities and new facilities since the 

most recent ICR.

6(g) Burden Statement

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

is estimated to average 388 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 

Docket ID Number EPA-HQ-OECA-2012-0499. An electronic version of the public docket is 

available at http://www.regulations.gov/ which may be used to obtain a copy of the draft 

collection of information, submit or view public comments, access the index listing of the

Assumptions:

a..

 We have assumed that the average number of respondents that will be subject to the rule will be 1,727. There will be 45 additional new sources that will 

become subject to the rule over the three-year period of this ICR.

b.

 This ICR uses the following labor rates: Technical $100.23 ($47.73 + 110%); Managerial $121.44 ($57.83+ 110%); and Clerical $50.51 ($24.05 + 110%).

These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 2012, “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.

 EPA estimates that there will be 26 new gas-fired steam generating units per year (which require NOx controls), 13 new coal-fired steam generating units per

year (which require SO2, NOx, and PM controls), and 6 new biomass/wood-fired steam generating units per year (which require NOx and PM controls).

d.

 One-time only costs associated with the anticipated 45 new sources per year over the next three years. According to the 2003 ICR renewal, approximately half

of all new sources will submit a monitoring plan.

e.

 Assume 20 percent of initial performance tests and CEMS demonstrations are repeated due to failures.

f.

 According to the 2003 ICR renewal, there are 640 sources that must report SO2 emissions, 622 sources that must report PM emissions, and 1,322 sources that 

must report NOx emissions. Because these existing source estimates were from 2003, this ICR renewal adds additional sources, based on note (b), to account for

new steam generating units built since 2003. Using this approach, EPA estimates 117, 171, and 405 additional sources must report SO2, PM, and NOx emissions, 

respectively.

g.

 Assume that 20 percent of respondents will choose to report quarterly.

h.

 Assume the 20 percent of units are found to be in excess of emission standard and 80 percent are found not to be in excess.

i.

 Assume that 25 percent of units have in situ CEMS and 75 percent have extractive CEMS.

Assumptions:

a..

 We have assumed that the average number of respondents that will be subject to the rule will be 1,727. There will be 45 additional new sources that will 

become subject to the rule over the three-year period of this ICR.

b.

 This cost is based on the average hourly labor rate as follows: Technical $46.21 (GS-12, Step 1, $28.88 + 60%); Managerial $62.27 (GS-13, Step 5, $38.92 +

60%); and Clerical $25.01 (GS-6, Step 3, $15.63 + 60%). This ICR assumes that Managerial hours are 5 percent of Technical hours, and Clerical hours are 10
23

percent of Technical hours. These rates are from the OPM, 2012 General Schedule, which excludes locality, rates of pay. The rates have been increased by 60

percent to account for the benefit packages available to government employees.

c.

 All new plants subject to the standard must provide reports of these events as required by section 60.7. These are one-time-only costs associated with the

anticipated 45 new sources per year over the next three years. According to the 2003 ICR renewal, approximately half of all new sources will submit a

monitoring plan.

d.

 EPA estimates that there will be 26 new gas-fired steam generating units per year (which require NOx controls), 13 new coal-fired steam generating units per

year (which require SO2, NOx, and PM controls), and 6 new biomass/wood-fired steam generating units per year (which require NOx and PM controls).

e.

 According to the 2003 ICR renewal, there are 640 sources that must report SO2 emissions, 622 sources that must report PM emissions, and 1,322 sources that

must report NOx emissions. Because these existing source estimates were from 2003, this ICR renewal adds additional sources, based on note (b), to account for

new steam generating units built since 2003. Using this approach, EPA estimates 117, 171, and 405 additional sources must report SO2, PM, and NOx emissions,

respectively.

f.

 We assume that 20 percent of respondents will choose to report quarterly.
