NEW SOURCE PERFORMANCE STANDARDS (NSPS) FOR STATIONARY SPARK 

IGNITION INTERNAL COMBUSTION ENGINES (40 CFR PART 60, SUBPART JJJJ)

1. IDENTIFICATION OF THE INFORMATION COLLECTION

(a) Title of the Information Collection

“NSPS for Stationary Spark Ignition Internal Combustion Engines (40 CFR part 60, 

subpart JJJJ), ICR 2227.02, OMB Control Number 2060-NEW.” 

(b) Short Characterization

This supporting statement addresses information collection activities that would be 

imposed by the “Standards of Performance for Stationary Spark Ignition Internal Combustion 

Engines,” 40 CFR part 60, subpart JJJJ. These standards fulfill the requirements of section 111 

of the Clean Air Act (CAA) as amended in 1990, which requires the EPA to promulgate 

standards for stationary internal combustion engines. The EPA has determined that for purposes 

of promulgating new source performance standards (NSPS) regulations, the stationary internal 

combustion engine source category should be split into two source categories - compression 

ignition (CI) engines and spark ignition (SI) engines. The NSPS for stationary CI engines were 

published on July 11, 2006 (71 FR 39154).

The information collection activities in this ICR include initial notifications for noncertified engines greater than 500 hp, records of engine maintenance for all SI internal 

combustion engines (ICE), records of operating hours for emergency SI ICE, performance test 

data for owners and operators of non-certified stationary SI engines, and test data and activities 

associated with obtaining engine certification for engine manufacturers. The information 

collection activities will enable the EPA to determine initial and continuous compliance with the 

requirements of the final rule.

2. NEED FOR AND USE OF THE COLLECTION

(a) Need/Authority for the Collection

The EPA is required under section 111 of the CAA to establish standards of performance 

for new stationary sources that reflect the 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. The Agency 

refers to this charge as selecting the best demonstrated technology. Section 111 also requires 

that the Administrator review and, if appropriate, revise such standards every four years.

In addition, Section 114(a) States that:

. . . the Administrator may require any owner or operator subject to any requirement of 

this Act to (A) establish and maintain such records; (B) make such reports; (C) install, 

use, and maintain such monitoring equipment or methods (in accordance with such 

methods at such locations, at such intervals, and in such manner as the Administrator 

shall prescribe); (D) sample such emissions; (E) keep records on control equipment 

parameters, production variables or other indirect data when direct monitoring of 

emissions is impractical; (F) submit compliance certifications; and (G) provide such other 

information as he may reasonably require.

Certain reports are necessary to enable the Administrator to identify stationary SI engines 

subject to the regulation and to determine if the standards are being achieved.

(b) Practical Utility/Users of the Data

The information will be used by the EPA to identify sources subject to the NSPS and 

ensure that the emission standards are being met. Records and reports are necessary to enable 
3

the EPA to identify facilities that may not be in compliance with the requirements. Based on 

reported information, EPA will decide which facilities should be inspected and what records or 

units should be inspected at the facilities. The records that facilities maintain will indicate to 

EPA whether facility personnel are operating and maintaining the equipment properly.

3. NONDUPLICATION, CONSULTATIONS, AND OTHER COLLECTION 

CRITERIA

(a) Nonduplication

Duplication in the reporting of stationary SI engine information is not anticipated. If the 

standard has not been delegated, the information is sent 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 regulation to implement the Federal regulation, 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 standard. Therefore, no duplication exists.

(b) Public Notice Required Prior to ICR Submission to OMB

A public notice of this collection will be provided in the final NSPS.

(c) Consultations

EPA has met with the Engine Manufacturers Association (EMA) on several occasions, as 

well as other affected entities that will be subject to the new emission standards. The public also 

had the opportunity to review and comment on the proposed NSPS and the ICR during the 

specified comment period.

(d) Effects of Less Frequent Data Collection

The frequency of the data collection requirements was chosen by the EPA to provide 

reasonable assurance that engines are in compliance with the standard. Annual reporting for 

certifying engine families is necessary to align with the regulatory requirement to certify engine 

families every year. 
4

(e) General Guidelines

None of the reporting or recordkeeping requirements contained in the final NSPS for 

stationary SI ICE violate any of the regulations established by OMB in CFR 1320.5. 

(f) Confidentiality

The type of data that would be required from owners and operators is principally

owner/operator and engine identification information and would not be confidential. If any 

information is submitted to the EPA for which a claim of confidentiality is made, the information 

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

subpart B -- Confidentiality of Business Information. 

We hold information from the engine manufacturers as confidential until the associated 

engines are available for purchase. Manufacturers may submit proprietary information, 

consisting generally of sales projections and certain sensitive technical descriptions. We grant 

confidentiality in accordance with the Freedom of Information Act, EPA regulations at 

40 CFR part 2, subpart B, and class determinations issued by our Office of General Council.

(g) Sensitive Questions

This section is not applicable because the ICR does not involve matters of a sensitive 

nature.

4. THE RESPONDENTS AND THE INFORMATION REQUESTED

(a) Respondents/NAICS Codes

Respondents are owners or operators of new, modified or reconstructed stationary SI 

ICE, as well as manufacturers of stationary SI ICE. These standards affect any industry, State, 

local, or tribal government using a stationary SI internal combustion engine. The North 

American Industrial Classification System (NAICS) codes for facilities using stationary SI ICE 

affected by the regulation include: 2211 (Electric Power Generation, Transmission, or 

Distribution), 622110 (Medical and Surgical Hospitals), 335312 (Motor and Generator 

Manufacturing), 33391 (Pump and Compressor Manufacturing), and 333992 (Welding and 
5

Soldering Equipment Manufacturing), 486210 (Pipeline Transportation of Natural Gas), 211111 

(Crude Petroleum and Natural Gas Production), 2111112 (Natural Gas Liquids Producers), and 

92811 (National security).

(b) Information Requested

(i) Data Items: Attachment 1, Source Data and Information Requirements, 

summarizes the recordkeeping and reporting requirements of this regulation for owners and 

operators of stationary SI ICE. In addition, manufacturers are required to submit an application 

for certification, including emission data and other descriptive information for each engine 

family subject to the emission standards. 

(ii) Respondent Activities: The respondent activities required by the regulation as 

they relate to owners and operators as well as engine manufacturers are provided under the first 

column of Tables 1 through 3, introduced in section 6(a).

(iii) Summary of Requirements: The information collection activities in this ICR for 

owners and operators of stationary SI ICE include initial notifications for non-certified engines 

greater than 500 hp, records of proper engine maintenance, the operating hours of emergency SI 

ICE, and any performance test data used to demonstrate compliance for non-certified engines or 

certified engines operating in a non-certified manner (if they are greater than 100 hp). 

Manufacturers of certified SI ICE must follow the procedures outlined in the final rule to certify

certain stationary SI ICE. The rule requires facilities to meet emission limitations for nitrogen 

oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC), non-methane hydrocarbons 

(NMHC), and volatile organic compounds (VOC). For about half of owners and operators of SI 

ICE less than 500 hp, EPA expects that compliance will be demonstrated through purchasing a 

certified stationary SI ICE. Owners and operators of non-certified engines can demonstrate 

compliance by submitting performance test results from a similar engine or by submitting engine 

manufacturer or control device vendor information that shows that the engine will meet the 
6

emission limitations. Alternatively, if none of the information described is available, owners and 

operators of non-certified stationary SI ICE can demonstrate compliance by conducting a 

performance test. The EPA estimates that the majority of engines greater than 500 hp will not be 

certified. It is assumed that stationary SI ICE will remain in continuous compliance if the engine 

is a certified engine. Performance tests for non-certified engines that are greater than 500 hp 

must be repeated every 3 years or 8,760 hours, whichever comes first. 

Owners and operators of emergency stationary SI engines are required to install a nonresettable hour meter to monitor the total number of hours operated. Information EPA has 

obtained indicates that an hour meter is typically included with the engine so no separate cost for 

the hour meter was estimated. The information will be used to ensure that owners and operators 

do not exceed the number of hours allowed by the NSPS for maintenance and testing purposes, 

i.e., 100 hours per year. Owners and operators must also keep records of why the engine was 

operated.

5. THE INFORMATION COLLECTED -- AGENCY ACTIVITIES, 

COLLECTION METHODOLOGY, AND INFORMATION MANAGEMENT

(a) Agency Activities

A list of Agency activities for the first 3 years following the effective date of the standard 

is provided in Tables 4 through 6, which are introduced in section 6(c).

(b) Collection Methodology and Management

Data obtained during periodic visits by EPA personnel, from records maintained by the 

respondents, and from information provided in notifications will be tabulated and published for 

internal EPA use in compliance and enforcement programs. Records of measurements, 

maintenance, reports, and records must be retained for two years following the date of the item.

(c) Small Entity Flexibility

Minimizing the information collection burden for all sizes of organizations is a 

continuing effort for the EPA. The final rule applies to engine manufacturers as well as owners 
7

and operators of stationary SI ICE. To limit the impact on small entities, only sources with noncertified engines with a maximum hp greater than 500 must submit an initial notification. 

However, owners and operators of all SI ICE must conduct performance tests on all non-certified

engines (unless the engine is a certified engine less than 100 hp operated in a non-certified 

manner), but only engines greater than 500 hp have to conduct subsequent testing. It is currently 

estimated that 7,694 new non-certified engines will be sold in 2008. Approximately 6,000 of 

these non-certified engines are less than 500 hp. More than 1,000 of these engines are less than 

50 hp.

The majority of the responsibility for small engines falls on the engine manufacturers. 

Engine manufacturers are responsible for ensuring that the engines will meet the emission 

limitations during its entire useful life. We expect more small engines will be certified by engine 

manufacturers than large engines. In addition, we expect more small engines will already be 

certified for nonroad use than large engines. Thus, small entities will be required to conduct 

fewer performance tests than large sources, reducing the impact on small sources. Furthermore, 

although the recordkeeping and reporting requirements are the same for small and large 

businesses, these requirements are considered the minimum needed to ensure compliance and, 

therefore, cannot be reduced further for small businesses.

(d) Collection Schedule

Owners and operators who must submit an initial notification must submit the initial 

notification no later than 30 days after the date construction or reconstruction commences. 

Records of hours of operation for emergency stationary SI ICE and justification of why the 

engine was operated must be maintained continuously. Owners and operators of non-certified SI

ICE must conduct initial performance tests according to the schedule in 40 CFR 60.8(f). Owners 

and operators of non-certified SI ICE that are greater than 500 hp must conduct subsequent 

performance tests every 3 years or 8,760 hours, whichever comes first. Owners and operators of 

all SI ICE must record any maintenance conducted on the engine. Other reporting requirements 
8

are associated with engine certification to the emission standards, which begin to apply as early 

as July 2007 for some engines. 

6. ESTIMATING THE BURDEN AND COST OF THE COLLECTION

(a) Estimating Respondent Burden

The stationary SI internal combustion engine NSPS is estimated to affect an average of 

about 16,500 new engines in each of the next 3 years, or a total of nearly 50,000 engines over 3 

years. Of the 16,500 new engines each year, it is estimated that about 50 percent of this total will 

be certified by the engine manufacturer; however, the percentage of engines certified by the 

manufacturer varies with engine size, type and fuel. For engines 25-50 hp, it was estimated that

50 percent of engines with any type of fuel will be certified. It is estimated that all gasoline and 

rich burn liquid petroleum gas (LPG) fired engines above 50 hp will be certified. Manufacturers 

are expected to certify approximately 50 percent of lean burn engines and engines fired with 

fuels other than gasoline or LPG with a maximum hp less than 500. Only 20 percent of engines 

with a maximum hp greater than or equal to 500 hp will be certified. 

Only non-certified engines greater than 500 hp need to submit an initial notification. 

Owners and operators will demonstrate compliance by purchasing certified stationary SI ICE or 

conducting performance tests. If compliance is achieved using performance testing and the 

maximum hp of the engine is greater than 500, additional performance tests are required every 3 

years or 8,760 hours, whichever comes first. For this analysis, it was assumed that only one 

performance test would be conducted for any one engine in the first 3 years. Owners and 

operators of emergency engines will be required to keep records of the number of hours during 

emergency and maintenance and testing. Owners and operators of any type SI ICE must record 

all maintenance conducted on the engine.

(b) Estimating Respondent Costs

The information collection activities for sources subject to these requirements are presented in 
9

Tables 1 through 3. Certification costs for engine manufacturers were estimated in Table 5.2.1-4 

of the document, “Final Regulatory Support Document: Control of Emissions from Unregulated 

Nonroad Engines.” This cost includes the cost of certifying the engine to the emission standards

and the cost for in-use testing and upgrades to the facility. Adjusting these costs to 2005 dollars 

using the consumer price index, certification costs of $13 per engine for 25 to 300 hp engines, 

$32 for 300 to 600 hp SI engines, and $153 for greater than 600 hp engines were used to estimate 

certification costs. The number of engines estimated to be certified by engine manufacturers was 

based on the percentages given in paragraph 6(a) reduced by the number of engines that are 

already certified for nonroad use. Engine manufacturers provided estimates of the number of 

engines that will be certified to EPA small engine regulation Part 90. These estimates were 

similar to those in paragraph 6(a). 

To certify SI engines for stationary use that have been certified for nonroad use, the 

source must submit the nonroad certification information for approval. This only occurs once for 

each engine family. Since no information is currently available for the number of SI engine 

families, it was assumed that the number of families is similar to CI engines. Hence it was 

assumed that 200 SI engine families will have been certified for nonroad use. It is assumed that 

only one technical person-hour is necessary to submit approval certification for use as a 

stationary engine that already certified for nonroad use. 

Non-certified engines would require an initial compliance test, which was estimated to 

cost $1,000 per engine using portable analyzers. This would cover costs to test all regulated 

pollutants. The NSPS impact for this category of engines includes the cost of notification and 

recordkeeping, each of which was estimated to be 1 hour per year. 

The total cost for each respondent activity includes labor costs. Labor rates, on a perhour basis, are taken from the Bureau of Labor Statistics web site 

http://www.bls.gov/news.release/ecec.toc.htm) as posted for December 2005, except when noted

otherwise in the tables. The base labor rates are $29.24 for technical/professional personnel, 

$33.98 for management, and $14.30 for clerical. The total compensation rate is $40.62 for 

technical/professional personnel, $48.56 for managerial, and $20.31 for clerical. This accounts 

for paid leave, insurance, etc. The compensation rates were then adjusted by an overhead and 

profit rate of 167 percent. The final total wage rates are $68 for technical/professional personnel, 

$81 for management, and $34 for clerical. 

(c) Estimating Agency Burden and Cost

Because the information collection requirements were developed as an incidental part of 

standards development, no costs can be attributed to the development of the information 

collection requirements. Because reporting and recordkeeping requirements on the part of the 

respondents are required under section 111 of the CAA, no operational costs will be incurred by 

the Federal government. Examination of records to be maintained by the respondents would 

occur incidentally as part of the periodic inspection of sources that is part of the EPA’s overall 

compliance and enforcement program and, therefore, is not attributable to the ICR.

The Agency burden and cost estimates include only those items where the government 

would incur additional costs as a result of the information collection. These costs include user 

costs associated with the review and analysis of the reported information. These are presented in 

Tables 4 through 6.

The hourly burden for review of reports was estimated through discussion with personnel 

from local agencies who review these types of reports. Each report reviewed for certification 

represents an engine family. For this analysis, the number of SI engine families were assumed to 

be the same as the number of CI engine families (i.e., 200 engine families currently certified for 

nonroad use and 35 currently non-certified engine families). Labor rates for Federal employees 

are based on the January 2006, Office of Personnel Management pay rates for General Schedule 

employees (see http://www.opm.gov/oca/06tables/html). The pay rates were multiplied by the 

standard government benefits multiplication factor of 1.6. The resulting average hourly labor

costs are $48 for technical personnel, $80 for management, and $28 for clerical.

To oversee the certification program for the nonroad SI engine rule, EPA estimated that 

the Agency’s burden would be approximately 2,500 hours or $100,000. This was based on 

projecting 50 hours per week at $40 per hour. The number of nonroad engine families expected 

to be certified is 1,077. The Agency’s burden per engine family would therefore be 

approximately 2.3 hours. For the engine families that are stationary only and that will have to 

conduct all elements of certification, the EPA believes it is appropriate to assume the same level 

of effort, i.e., about 2 hours per engine family. However, for engine families that are currently

certified for nonroad use, but that will additionally have to be certified for stationary use (200 

engine families), minimal effort is expected to be involved and EPA estimates that the Agency

will spend approximately 1 hour of technical labor for these engine families.

The total annual average burden for the Agency is 25,754 hours and $1,225,064. 

(d) Estimating the Respondent Universe and Total Burden and Costs

The respondent universe was estimated using information developed by Power Systems 

Research. This information included new engine sales from 1990 to 2002. The average annual 

increase in engine sales was added for each year to estimate the 2008-2010 new engine sales. 

Information provided by engine manufacturers allowed distribution of the engines by engine 

type. The total burden is calculated by adding the cost of performance testing for engine 

certification and for non-certified engines and the cost of technical, management, and clerical 

hours per year. The technical hours are calculated by multiplying the total hours per respondent 

by the number of respondents per year for each respondent activity. Management and clerical 

hours are assumed to be 5 percent and 10 percent of the technical hours, respectively, unless 

noted otherwise.

The total cost is calculated by summing the labor and performance testing costs. The 

labor costs are determined by multiplying the total labor hours by the total wage rate for each 

labor category. Total cost is presented in the far right column of each table (Tables 1-3).

(e) Bottom Line Burden Hours and Cost Tables

(i) Respondent Tally A breakdown for each of the collection, reporting, and 

recordkeeping activities required by the NSPS is presented in Tables 1 through 3. The estimate 

of total annual hours requested from the respondents was based on the assumptions outlined in 

section 6(d) of this supporting statement. The EPA estimated the respondent burden by totaling 

the hours for the first 3 years after the implementation of the NSPS for technical, managerial, and 

clerical staff at the facility, and then dividing that total by three to determine the average 

annualized burden. The 3-year summary results are presented in Table 7. The total number of 

responses for these respondents over the first 3 years after the implementation of the NSPS is 

estimated to be 80,674, or an average of 26,891 per year. For the first 3 years after the 

implementation of the NSPS, the EPA estimates that industry would expend 31,693 hours

annually at a cost of about $10 million per year to meet the recordkeeping and reporting 

requirements and requirements related to obtaining engine certification and demonstration of 

compliance.

(ii) The Agency Tally A breakdown for each of the Agency activities required for the 

NSPS is provided in Tables 4 through 6. The bottom line Agency burden hours and costs, 

presented in Table 8, are calculated by totaling the hours per year for technical, managerial, and 

clerical staff, and by totaling the cost column. The average annual burden is calculated by

dividing the 3-year total by three. The estimated average annual burden, over the first 3 years, 

for the Agency would be 25,754 hours at a cost of $1,225,064 per year.

(iii) Variations in the Annual Bottom Line There is very little variation in the number 

of respondent labor hours for the first three years. Only a slight increase in the number of 

engines sold (1.5 percent) makes each subsequent year slightly higher. The typical number of 

respondent labor hours is around 2 hours (e.g., year 1: 31,175/16,285 = 1.91). This represents a 

total cost to this respondent of $620 (e.g., year 1: $9,849,188/16,285 = $605).

The total burden and cost estimates for the first 3 years after the NSPS is promulgated are 
19

given in Tables 1 through 3 and Table 7. The slight yearly increase in total activity and

respondent burden and cost is shown in the tables. In years 1, 2, and 3, the total costs are 

$9,849,188; $9,851,400; and $10,017,042; respectively (see Tables 1 through 3 and 7). In the 

first year, 2,142 engines will be required to submit initial notifications, 3,465 will submit 

complete certifications for stationary use, 200 engine families will submit applications for 

nonroad engines to be approved for stationary use, 16,285 engines will record maintenance and 

421 emergency engines will be recording their hours of operation during non-emergencies. In 

the second year, 2,204 more engines will be required to submit initial notifications, 3,737 will 

submit complete certifications for stationary use, 200 engine families will submit applications for 

nonroad engines to be approved for stationary use, 16,538 engines will record maintenance and 

427 emergency engines will be recording their hours of operation during non-emergencies. By

the third year, 2,275 more engines will be required to submit initial notifications, 3,771 will 

submit complete certifications for stationary use, 200 engine families will submit applications 

fornonroad engines to be approved for stationary use, 16,791 engines will record maintenance 

and 433 emergency engines will be recording their hours of operation during non-emergencies. 

The total number of agency hours for review of initial notifications increases slightly each year 

because the number of new engines increases slightly each year. As estimated, the agency’s 

effort related to engine certification applications does not change from year to year because the 

same number of engine families will be certified each year. The largest portion of agency

burden required by the SI NSPS, nearly 90 percent, is reviewing performance tests that 

demonstrate compliance for engines that are not certified. The total number of agency hours for 

years 1, 2, and 3 ranges from 25,559 to 26,102. The corresponding agency cost for activities 

during these years ranges from $1,215,812 to $1,241,690 (see Table 8). 

(f) Reasons for Change in Burden

This is the initial estimation of burden for this ICR; therefore this section does not apply.

(g) Burden Statement

 The annual public reporting and recordkeeping burden for this collection of information 
21

is estimated to average less than 2 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 currently

valid OMB control number. The OMB control numbers for EPA's regulations are listed in 40 

CFR part 9 and 48 CFR chapter 15.
