Revisions to the Economic Impacts and Burden Estimates for the Rule Titled: Review of 

New Sources and Modifications in Indian Country 

This addendum summarizes the revised qualitative assessment of the economic and burden 

impacts of the rule titled: Review of New Sources and Modifications in Indian Country. Burden 

and costs estimates have changed from those estimated under the previous versions of the 

Economic Impact Analysis (EIA) and the Supporting Statement (SS) for this rule due to a change 

in policy before the rule was finalized. 

At the time the original EIA and SS were written, we planned to delay the applicability date of 

the rule for true minor sources that might be subject to the minor NSR program for a period of 18 

months from the rule’s effective date (60 days after the final rule is published). However, to 

address commenters concerns about EPA’s ability to implement this NSR permitting program in 

a timely manner and to provide additional time for EPA Regions to prepare for their duties as the 

Federal permitting authority, including the development of additional permitting tools, we have 

extended the applicability date of the rule for true minor sources for an additional 18 months for 

a total applicability delay of 36 months from the effective date of the final rule. In addition, 

sources eligible to seek coverage under a general permit will be subject to that general permit 4 

months after the general permit is effective (6 months after the general permit is published) 

unless the source opts to apply for a site-specific permit at the time the source had to apply for 

that general permit.

Therefore and based on these revisions, we are reducing the permitting burden and cost for both 

the regulated community and the agency. Under the revised provisions, no permits will be 

required for new and modified true minor sources during the initial 36 months after the effective 

date of the rule, unless a general permit is available before the 36 month applicability date for the 

source category for which the source owner is seeking a permit. Sources will still be required to 

register, as in the previous version of the rule, within the first 18 months after the minor NSR 

rule effective date or 90 days after the source begins operation, whichever is later. 

Reduction in Economic Impacts Based on Rule Revisions

In the EIA, we present a range of estimated costs and impacts for the first 3 years after the 

effective date of the rule. The “Lower Bound” costs in the EIA only include Monitoring, 

Recordkeeping and Reporting (MRR) costs, computed under the conservative assumption that all 

facilities choose source-specific permitting (cost and burden for the development and 

implementation of general permits is unknown at this time). Under the “Upper Bound” cost 

estimates some facilities are assumed to be subject to BACT. 

Previously, Lower Bound costs, which are based only on MRR costs, were estimated for the first 

three years after the effective date of the rule to total $22.9 million across all source categories. 

Under the revised provisions, costs for this initial three-year period would total $2.7 million. The 

$20.2 million reduction in costs over the initial three-year period is wholly owed to reduction in 

permitting burden for new and modified true minor sources during the second18-month interval 

of the current 36-month applicability delay after the effective date of the rule. 

Furthermore, previous Upper Bound costs during the first 3 years after the effective date of the 

rule, which include compliance costs for BACT controls for some facilities in addition to MRR 

costs, were estimated in the EIA to total $24.2 million. Under the revisions, the Upper Bound 
2

cost is $2.9 million. This reduction of $21.3 million is also wholly due to the reduction in 

permitting burden for new and modified true minor sources during the second 18-month interval 

of the current 36-month applicability delay after the effective date of the rule.

Burden Estimates in Supporting Statement

Estimated Reduction in Burden for Affected Sources. As explained previously, no permits 

will be required for new and modified true minor sources during the initial 36 months after the 

effective date of the rule, unless a general permit is available before the 36 month applicability 

date for the source category for which the source owner is seeking a permit. Sources will still be 

required to register, as in the previous version of the rule, within the first 18 months after the 

minor NSR rule effective date or 90 days after the source begins operation, whichever is later. 

The associated estimated hour and cost burden to industry are shown in Table 1 (Capital and 

One-Time Cost Burden) and Table 2 (Total Annual Burden) below. We estimate that the level of 

effort and cost to register under the rule and to apply for coverage under a general permit is 

similar. Therefore, the overall burden for all affected sources is projected to decrease from $22.8 

million to $2.7 million, a reduction of $20.1 million and about 1.8 million hours. The burden 

associated with affected true minor sources is projected to decrease from $20.4 million to $0.3 

million. The burden for new true minor sources is projected to decrease from $18.1 million to 

$0.2 million. The burden for modified true minor sources is projected to decrease from $2.3 

million to about $30 thousand. 

The overall hours burden for all affected sources is projected to decrease from 2.1 million hours 

to 0.2 million hours, a reduction of 1.8 million hours. New true minor sources account for 1.6 

million of the reduction and modified true minor sources account for the remaining 0.2 million 

hours.

Estimated Reduction in Agency Burden: Similarly, the administrative burden to the Agency, 

shown in Table 3 below, is projected to be lower under the revised provisions. Assuming all new 

and modified true minor sources are required to either register or apply for coverage under a 

general permit during the first 36 months following the rule’s effective date, the Agency overall 

burden is projected to decrease from $17.1 million to $6.9 million, a reduction of $10.2 million. 

In terms of hours, the Agency burden falls from 162,470 hours to 76,550 hours, a reduction of 

approximately 85,900 hours. This decrease is wholly owed to not requiring sources to seek sitespecific permits for true minor sources during the second 18-month interval of the current 36-

month applicability delay after the effective date of the rule. The burden associated with true 

minor sources is projected to decrease from $11.0 million to $0.8 million, a reduction of $10.2 

million.

These estimates, however, do not include the Agency cost burden for development and 

implementation of new general permits as those costs are unknown at this time.

a New minor sources and modifications to minor sources in the first 36 months following the effective date of the rule are subject to one-time registration only unless a general 

permit becomes available for the source category. Capital costs and cost of one-time activities to register or apply for coverage under a general permit are estimated to be $433. 

Annualized based on a repayment period of 10 years and an interest rate of 7 percent, the amount is $62. b Existing synthetic minor sources will be required to obtain a new permit. The capital costs and cost of one-time activities per source is estimated to be $4,341. Annualized based 

on a repayment period of 10 years and an interest rate of 7 percent, the amount is $618. 

The capital costs and cost of one-time activities (i.e., the sum of all one-time costs shown in Attachment 1) are $13,290 for minor modifications at major sources or new synthetic 

minor sources. Annualized based on a repayment period of 10 years and an interest rate of 7 percent, the amount is $1,892. 

The capital costs and cost of one-time activities for new major sources in nonattainment areas and major modifications to major sources in nonattainment areas are $17,138. 

Annualized based on a repayment period of 10 years and an interest rate of 7 percent, the amount is $2,440. 

These values include the non-labor capital costs ($25, $31, $1,340 or $1,185), shown above.

Supporting Statement for the

Review of New Sources and Modifications in Indian Country Rule

Prepared by

Office of Air Quality Planning and Standards

January 2011

PART A OF THE SUPPORTING STATEMENT

1. Identification of the Information Collection 

(a) Title of the Information Collection.

Review of New Sources and Modifications in Indian Country rule. The tracking number 

is EPA ICR number 1230.27 (Final rule).

(b) Short Characterization/Abstract.

The final action will establish nationally applicable regulations to implement a permitting 

program in Indian country, which will regulate the construction and modification of 

stationary sources of air pollution and allow certain new and existing stationary sources 

to voluntarily accept federally enforceable emission limits in order to avoid major source 

regulations. With this action, the U.S. Environmental Protection Agency (EPA) is 

finalizing regulations to regulate new and modified minor stationary sources and minor 

modifications at existing major sources in Indian country and also to regulate new major 

sources and major modifications in portions of Indian country that are not in attainment 

of the National Ambient Air Quality Standards (NAAQS), i.e., nonattainment areas. 

These rules will be implemented by EPA, or a delegate tribal agency assisting EPA with 

administration of the rules, until replaced by an EPA-approved implementation plan for 

an area of Indian country.

Potential respondents are owners or operators of all new and modified minor stationary 

sources and major sources with minor modifications in Indian country, and new major 

stationary sources and major modifications at such sources located in nonattainment areas 

in Indian country. Although existing minor stationary sources will not be regulated under

this rule, existing true minor sources will be required to register, and most existing 

synthetic minor sources will need a new permit.

The minor-source regulations set forth the procedures and terms under which the 

Administrator will issue new source review (NSR) construction permits for stationary 

sources of air pollution in Indian country, pursuant to section 110 (a)(2)(C) of the Clean 

Air Act as amended in 1990 (CAA). These regulations will apply to all new and 

modified minor stationary sources and minor modifications at major sources in Indian 

country. All respondents to the federal minor NSR rule will be required to obtain an 

NSR construction permit. Respondents will be required to use any control technology 

determined to be appropriate by the reviewing authority on a case-by-case basis to meet 

the air quality needs for that area. 

Respondents will maintain records of specific information to ensure that the rule 

requirements are being achieved and maintained. These requirements are listed in 

Attachment 1. 
8

2. Need For and Use of the Collection

(a) Need/Authority for the Collection.

EPA is authorized to protect air quality by directly implementing provisions of the CAA 

throughout Indian country. In the preamble to the CAA Tribal Authority Rule, EPA 

stated the intention to draft nationally applicable regulations to implement a permitting 

program in Indian country that will regulate construction and modification of stationary 

sources of air pollution (63 FR 7254, February 12, 1998). 

Certain records and reports are necessary for EPA or the tribal agency (with delegation of 

the program or EPA-approved Tribal Implementation Plan), for example, to (1) identify 

any stationary sources not subject to the NSR standards, identify new or modified major 

and minor sources in Indian country subject to the rules, and confirm the compliance 

status of major and minor sources in Indian country subject to the rules; and (2) ensure 

that the major and minor source-control requirements are being achieved. 

(b) Practical Utility/Users of the Data.

The information will be used by EPA or tribal enforcement personnel to (1) identify 

major and minor sources, new or modified, subject to the rules; (2) ensure that any 

control technology (established on a case-by-case basis) is being properly applied; and 

(3) ensure that the emission-control devices are being properly operated and maintained 

on a continuous basis. 

3. Nonduplication, Consultations, and Other Collection Criteria

(a) Nonduplication.

A search of EPA's existing regulations and standards and on-going ICRs revealed no 

duplication of information-gathering efforts. However, should certain reports required by 

tribal, state, or local agencies duplicate information required by the Review of New 

Sources and Modifications in Indian Country rule ICR number 1230.27, a copy of the 

report submitted to the tribal, state, or local agency can be provided to the Administrator 

in lieu of the report required by the rule.

(b) Public Notice Required Prior to ICR Submission to the Office of Management and 

Budget (OMB).

The preamble to the final rule will give public notice of this ICR.

(c) Consultations.

In undertaking this rulemaking effort, EPA wanted to ensure that the tribes were included 

in the rulemaking process from the beginning of the rule development effort. To that 

end, on June 24, 2002, EPA sent letters to tribal leaders seeking their input on how we 

could best consult with the tribes on the rulemaking effort. We received responses from 

75 tribes. Of these 75 tribes, 69 designated an environmental staff member to work with 

us on developing the rules. Aside from the designated staff, many tribal leaders asked that 

we keep them informed of our progress through e-mail, meetings with the EPA Regional 

Offices, newsletters, and Web sites. However, 53 percent of the tribal leaders also 

requested direct phone calls or conference calls to discuss the subject. Only 16 percent of 
9

the respondents requested face-to-face consultation. Of these, only six tribes requested 

that senior EPA staff meet with tribal leaders.

As a result of this feedback, we developed a consultation plan that included three 

meetings held at the reservations of the Menominee Tribe in Wisconsin, the Mohegan 

Tribe in Connecticut, and the Chehalis Tribe in Washington. A fourth meeting was held 

in conjunction with the Institute of Tribal Environmental Professionals’ (ITEP) 10th

anniversary meeting in Flagstaff, Arizona. In addition to conducting these meetings, we 

also visited tribal environmental staff in Indian country. Over 30 tribes attended these 

meetings. As part of our outreach efforts to the tribes, we participated in numerous 

national and regional forums, including the National Tribal Forums sponsored by the 

ITEP, two National Tribal Air Association meetings, and meetings with tribal consortia, 

such as the National Tribal Environmental Council, United Southern and Eastern Tribes, 

Inter-Tribal Environmental Council, Inter Tribal Council of Arizona, and others.

Although much of our effort focused on outreach to the tribes, we also interacted with 

state and local air pollution control agencies during development of this rule. We had 

two meetings with the State and Territorial Air Pollution Program Administrators and the 

Association of Local Air Pollution Control Officers (STAPPA/ALAPCO) to present the 

draft rules.1

 After receiving all stakeholders’ feedback, we incorporated it to our 

rulemaking process to the extent possible and proposed the “Review of New Sources and 

Modifications in Indian Country” rules on August 21, 2006 (71 FR 48696). However, 

tribal government representatives expressed concerns that the long gap between 

consultation and action by EPA undermined the effectiveness of these interactions. 

Thus, after the rules proposal, we started an extensive outreach period in the years 2006 

and 2007 to inform and seek comments from the public, especially tribes. We sent more 

than 500 letters to tribal leaders to inform them about the proposal. We did not receive 

any formal responses to these letters and did not receive any request for formal 

consultation from the tribes, but they contacted us either through e-mail or phone calls 

and asked us to keep them informed of our progress through e-mail, meetings, trainings, 

newsletters, and/or Web sites. To enhance understanding of the proposal and what it 

would mean for reservations, we supplemented the 2006 outreach efforts by holding four 

trainings using Web conferencing, not only for tribes but also for EPA regional offices, 

air program managers, and Tribal organizations. We also held trainings in 2006 and, at 

the request of the tribes, for interested Tribal and other environmental professionals at the 

Pechanga Band of Luiseño Indians in California and Salt River Pima-Maricopa Indian 

Community in Arizona. In addition, we held trainings for all interested parties at Region 

5’s Tribal Air Meeting in Illinois (2006) and EPA's Region 10 office in Washington 

(2007). 

We participated in numerous national and regional forums, including the Institute of 

Tribal Environmental Professionals, National Tribal Air Association, and meetings with 

tribal consortia, such as the United Southern and Eastern Tribes. We also interacted with 

 1 STAPPA/ALAPCO is currently known as the National Association of Clean Air Agencies (NACAA)
10

state and local air pollution agencies during this outreach period and had meetings with 

the National Association of Clean Air Agencies.

Furthermore, we extended and reopened the comment period for the proposed rules twice 

(from November 20, 2006, to January 19, 2007, and from January 19, 2007, to March 20, 

2007) at the request of the tribes. During this time, we also recorded and presented a 

Web cast video for all interested stakeholders to train more environmental professionals 

about the NSR program and the rules themselves. 

Now that these rules have been finalized, we intend to conduct similar outreach efforts 

with all stakeholders, including conducting extensive training about what the rules are 

and how they can be implemented. 

(d) Effects of Less Frequent Collection.

If results were collected less frequently, there would be little assurance that each source 

was in continuous compliance with the NSR requirements. Also, EPA’s authority to take 

administrative action would be reduced.

(e) General Guidelines.

None of the recordkeeping or reporting requirements contained in the Review of New 

Sources and Modifications in Indian Country rule, 40 CFR Parts 49 and 51, or 

otherwise pertinent to this request, violate any of the regulations established by OMB in 5 

CFR 1320.6.

(f) Confidentiality.

Confidential business information will be handled using Agency guidelines on 

confidentiality, set forth in Title 40 Chapter 1, Part 2 Subpart B - Confidentiality of 

Business Information (see 40 CFR Part 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).

(g) Sensitive Questions.

Information to be reported consists of emissions data and other information that is not of 

a sensitive nature. No sensitive personal or proprietary data are being collected.

4. The Respondents and the Information Requested

(a) Respondents’ NAICS Codes.

Potential respondents are (1) owners or operators of all new minor stationary sources and 

all existing sources that propose minor modifications in Indian country, and (2) those new 

major stationary sources and major sources that propose modifications located in portions 

of Indian country that are in nonattainment areas. It is estimated that 3,803 new true 

minor sources of varying types will be subject to the rule requirements during the first 3 

years following promulgation of the rule. The North American Industry Classification 

System (NAICS) codes for these various minor source types are included in the economic 

impact analysis cost tables. Fifty-five new major sources are estimated to be built in 

Indian country during the first 3 years following promulgation of the rule. Based on our 

knowledge of major sources in Indian country, EPA expects that 5 percent of new major 
11

sources (three sources) will locate in a nonattainment area in Indian country during this 

period.

Entities potentially affected by this proposed action include sources in all industry 

groups. The majority of sources potentially affected (i.e., those expected to be affected in 

the first 3 years following promulgation) are in the following groups.

Entities potentially affected by this proposed action also will include Tribal governments 

that are delegated administrative authority to implement these federal regulations.

(b) Information Requested.

(i) Data items, including recordkeeping requirements.

All data in this ICR that are recorded and/or reported as required by the Review of New 

Sources and Modifications in Indian Country rule are identified in Attachment 1 and 

characterized in Section 6. The rule also requires 5 years of record retention.

(ii) Respondent activities.

The respondent activities required by the Review of New Sources and Modifications in 

Indian Country rule are identified in Attachment 1 and characterized in Section 7. These 

include preparation and planning activities, submittal of a permit application, and various 

reporting activities.

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

Information Management

(a) Agency Activities.

A list of EPA activities is provided in Attachment 2 and introduced in Section 5(c).

(b) Collection Methodology and Management.

It is expected that this information collection (i.e., all permit applications, reports, and 

facility registration) will involve hard-copy submittals by the respondents, although 

electronic filing is an option. Data and records maintained by the respondents are 

tabulated and used in compliance and enforcement programs. The records required by 

this regulation must be retained by the owner or operator for 5 years.

(c) Small Entity Flexibility.

The recordkeeping and reporting burden is the same for all entities, regardless of size. 

The requirements are viewed by the Agency as the minimum needed to ensure 

compliance and cannot be reduced further for small entities.

(d) Collection Schedule.

Data collection will begin after the effective date of the rule. The average total agency 

burden per affected source, provided in Attachment 2, is 42 hours. The schedule for 

reports required by the regulations is detailed below.

(i) All stationary sources that are subject to the rule must obtain an NSR permit before 

they begin actual construction.

(ii) Annual submittal of reports of any required monitoring, including the type and 

frequency of monitoring and a summary of results obtained by monitoring.

(iii) Prompt reporting of deviations from permit requirements, including those 

attributable to upset conditions as defined in the permit, the probable cause of such 

deviations, and any corrective actions or preventive measures taken. Within a permit, the 
13

Administrator shall define “prompt” in relation to the degree and type of deviation likely 

to occur and the applicable emission limitations.

6. Estimating the Burden and Cost of the Collection

This section presents the estimated burden to each new and modified affected source 

type. It also presents a breakdown of estimated costs, both per facility and nationwide. 

Agency burden and cost and burden is also presented. The following definitions apply to 

this section.

Annual costs: The expected costs per year, including annually recurring costs and 

annualized one-time costs.

Associated costs: Non-labor costs, such as travel, emission testing, or document delivery.

Burden: The total time, effort, or financial resources expended by persons to generate, 

maintain, retain, or disclose or provide information to or for a tribal or 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 requirements; search data sources; complete and review the collection of 

information; and transmit or otherwise disclose the information. Burden is measured in 

term of hours and dollars incurred. The average annual burden takes into account 

annualized, one-time costs and the annually reoccurring cost and includes labor and nonlabor costs.

Fringe benefits: any nonwage payment or benefit (e.g., pension plans, profit-sharing 

programs, vacation pay, and company-paid insurance programs) granted to employees by 

employers. 

Capital costs: Costs that occur one time only. Much of the initial permitting process will 

need to be done only once.

Labor costs: A product of labor hours and labor rate, summed for all labor types (legal, 

managerial, technical, and clerical).

Non-labor capital costs: One-time costs, not including one-time labor costs. Includes 

purchase and installation of capital equipment.

Overhead costs: Expenses (such as for lighting, maintenance, and rent of a business 

premises, advertising, computing, maintenance, security, and supervision) incurred in 

joint usage and, therefore, difficult to assign to or identify with a specific cost center 

(e.g., department, function, program).

Permitting costs: The labor and associated costs to a facility to fulfill the requirements for 

obtaining an NSR permit.
14

Registration costs: The labor and associated costs with registering an existing source as 

required by the rule.

(a) Estimating Respondent Burden.

The estimated burden was calculated based on EPA’s decision to delay implementation 

of the minor-source rule for 18 months following promulgation. Consequently, any new 

minor sources or modifications to existing minor sources coming on-line in the first 18 

months following the effective date of the rule will only be required to register. These 

sources will thus incur the same costs as existing minor sources, which are also required 

to register under the rule. New minor sources and modifications to minor sources after 

the first 18 months will be required to obtain a permit under the rule. 

(i) Minor sources.

The minor NSR permitting rule proposed in this action will apply to all new stationary 

sources and modifications in Indian country that are not subject to regulation as new 

major stationary sources or major modifications under parts C or D of Title I of the Act, 

and that meet the minor NSR thresholds as defined in the final rule. Existing true minor 

sources will not be affected unless they propose a modification above the minor NSR 

threshold.

New minor sources. The annual burden estimates are based on an estimated 3,803 new 

true minor source facilities coming on-line during the first 3 years following 

promulgation of the rule. Half of these are estimated to come on-line during the first 18 

months following the effective date of the rule. Therefore, we estimate that 1,902 

facilities will incur registration costs only, and 1,902 facilities will incur permitting costs.

Modifications to existing minor sources. EPA estimates that there are 32,891 existing 

true minor sources in Indian country. Assuming that a minor source makes a 

modification every 10 years (based on EPA’s experience with other standards), each year, 

there will be an estimated 3,289 facilities making modifications to their operations. 

However, based on EPA’s experience with other standards, it is anticipated that of these 

minor-source process/operational modifications, only 5 percent will result in emissions 

increases greater than the minor NSR threshold. Facilities in this group (164 facilities per 

year, or 492 over the first 3 years) that come on-line the first 18 months following 

promulgation will be required to register, and those that come on-line after the first 18 

months will be required get a minor-source NSR permit. As EPA noted in its 

memorandum on “New Source Review Year 2000 Adjustments,” September 6, 2000, 

industry has been able to build major new plants or make physical and operational 

changes at major existing sources without exceeding the major source and major 

modification thresholds. The same situation holds for minor sources. Sources are 

expected to avoid the minor NSR thresholds for same three reasons as noted for major 

sources: (1) installation of state-of-the-art control technologies; (2) replacement or better 

control of older, more polluting processes; and (3) engagement in effective pollutionprevention efforts. All of these actions result in significant reductions in air emissions 

beyond the baseline case. 
15

Half of these facilities (246) are estimated to make modifications during the first 18 

months following the effective date of the rule, and thus will only be subject to 

registration requirements. Therefore, during the first 3 years following promulgation, it is 

estimated that there will be 246 minor sources requiring permits as a result of 

modifications. Of these minor-source facilities requiring a permit, it is estimated that half 

(123) will incur control-device costs. This estimate is based on EPA’s experience with 

other standards.

With regard to the minor NSR permitting rule, the information-burden estimates for 

monitoring, testing, reporting, and recordkeeping are presented in Attachment 1. See 

Section 7 for the assumptions regarding the frequency of occurrence for the various 

respondent activities and their associated costs.

(ii) Major sources.

The NSR permitting regulations apply to all minor modifications to major stationary 

sources in Indian country and those new major stationary sources and major 

modifications to existing major sources located in portions of Indian country that are not 

in attainment of the NAAQS, i.e., nonattainment areas. 

New major sources. The rule will only result in an administrative change for new major 

sources in Indian country; this is because, although the regulatory mechanism to issue 

permits is not yet available, either in the form of a federal nonattainment NSR rule or a 

TIP, EPA will be required to implement the program in Indian country and will otherwise 

have to do source-specific federal implementation plans. As a result, there will be no 

new or additional burden on industry. As stated previously, EPA estimates that, at most, 

three new major sources will locate in a nonattainment area in Indian country during the 

first 3 years following promulgation of the rule. 

Major modifications in nonattainment areas. EPA data show that there are six existing 

major sources located in nonattainment areas in Indian country. The NSR rules will have 

little impact on these existing major stationary sources in Indian country because they 

will only affect such sources if they propose a major or minor modification, and none are 

expected to do so during the 3 years following promulgation.

Minor modifications to major sources. There are currently a total of 179 major sources 

located throughout Indian country. A portion of these will choose to make minor 

modifications during the first 3 years following promulgation. As previously noted 

above, industry has been able to build major new plants or make physical and operational 

changes at major existing sources without exceeding the major source and major 

modification thresholds. The same situation holds for minor modifications to major 

sources. Sources avoid the major and minor NSR thresholds for three reasons: 

(1) installation of state-of-the-art control technologies; (2) replacement or better control 

of older, more polluting processes; and (3) engagement in effective pollution-prevention 

efforts. All of these actions result in significant reductions in air emissions beyond the 

baseline case. Based on EPA’s experience with other standards, it is assumed that each 

major source will make a process or operational modification every 10 years (18 facilities 

per year), and that of these major source process/operational modifications, only 10 
16

percent (2 facilities per year) will result in greater than minor NSR threshold emission 

increases. These two facilities per year will be required to get a minor-source NSR 

permit. Under this scenario, there will be two major-source facilities in Indian country 

per year that make minor modifications, or six total over the first 3 years following 

promulgation of the rule. The burden costs and impacts are based on sources incurring 

costs associated with the respondent activities required by the Review of New Sources 

and Modifications in Indian Country rule. The burden costs and impacts are identified 

in Attachment 1 and characterized in Section 6. 

(iii) Synthetic minor sources.

The tribal NSR permitting rule will also allow new and existing stationary sources in 

Indian country to accept federally enforceable limits on their potential to emit any 

regulated air pollutant. These enforceable permit limits will enable sources to avoid 

regulation as new major stationary sources, and instead, be regulated under this proposed 

rule, and other applicable rules, as minor sources. Sources that voluntarily accept 

enforceable emission limits in order to avoid major NSR regulations are often referred to 

as “synthetic minor” sources. EPA believes that facilities could choose to do this to 

avoid Title V permitting or avoid being classified as a major source under the NSR or 

Maximum Achievable Control Technology (MACT) (National Emission Standards for 

Hazardous Air Pollutants [NESHAP]) programs. Based on information from EPA 

Regions, 24 new synthetic minor sources are expected during the first 3 years following 

promulgation.

(b) Estimating Respondent Costs.

(i) Estimating labor costs.

Labor rates and associated costs are based on Bureau of Labor Statistics (BLS) data. 

Technical, management, and clerical average hourly rates for civilian workers were taken 

from the September 2009 Employment Cost Trends 

(http://stats.bls.gov/news.release/ecec.t02.htm). Wages for civilian workers (white-collar 

occupations) are used as the basis for the labor rates, with a total compensation of 

$31.09/hour for technical, $54.52/hour for managerial and legal, and $23.11/hour for 

clerical. These rates represent salaries plus fringe benefits and do not include the cost of 

overhead. An overhead rate of 110 percent is used to account for these costs. The fullyburdened wage rates used to represent respondent labor costs are technical at $65, 

management and legal at $114, and clerical at $49. These labor rates are used in 

Attachment 1 to estimate total labor costs.

(ii) Estimating capital/startup operating and maintenance (O&M) costs.

Several of the monitoring, recordkeeping, and reporting (MRR) activities associated with 

the minor-source NSR rule occur only one time. These costs for affected minor sources 

are considered as capital costs in this analysis. The estimate of facility capital costs 

associated with the NSR permit program is shown in Attachment 1; activities in the 

attachment are noted as one-time or capital costs. The average total capital cost per 

facility is estimated over the first 3 years following promulgation as $13,290 per affected 

source. Of this amount, $1,340 are non-labor related capital costs for such one-time 

activities as air quality modeling analysis and emission source testing averaged over the 
17

frequency of occurrence. Total capital costs are presented in Table 1. Because no 

continuous emission monitoring is required and no additional costs will be incurred for 

continuous monitoring, the O&M costs for affected new and modified major and minor 

sources are considered zero for this rule. 

During the 3 years following promulgation, the expected affected new and modified 

facilities in Indian country include 3,803 new minor sources (1,902 during the second 18 

months); 492 modifications to minor sources (246 during the second 18 months); 3 new 

major sources in nonattainment areas; 6 minor modifications to existing major sources in 

attainment and nonattainment areas; and 24 new synthetic minor sources. No major 

modifications to existing major sources in nonattainment areas are expected. These new 

and modified affected sources will all incur the same MRR cost associated with the NSR 

permit program. As shown in Attachment 1, the average capital cost per facility is 

estimated over the first 3 years following promulgation as $13,290 per affected source.

There are 32,891 existing true minor sources located in Indian country. These sources are 

expected to incur a one-time registration cost. New minor sources and modifications to 

minor sources during the first 18 months after promulgation (1,902 and 246 facilities, 

respectively) also will only incur the cost of one-time registration. The average total 

capital cost per source is $433. There are 79 existing synthetic minor sources in Indian 

country that will incur a one-time permitting cost; the average total capital cost per source 

is $4,341. Estimated costs are presented in Table 1. 

(iii) Estimating annual costs.

The annualized cost of capital for the capital costs and one-time activities for new and 

modified minor sources after the first 18 months (i.e., $13,290), shown in Attachment 1, 

is $1,892 per year. Of this amount, $191 is attributable to the annualized non-labor 

capital costs. This is based on a repayment period of 10 years and an interest rate of 7 

percent. The annual and reoccurring costs as shown in Attachment 1 amount to a burden 

cost of $7,543 per year. The total annual burden cost is estimated at $9,435 per year per 

affected source, i.e., $1,892 plus $7,543. 

The annualized cost of capital for the capital costs and one-time activities for new and 

modified major sources in nonattainment areas (i.e., $17,138), shown in Attachment 1, is 

$2,440 per year. Of this amount, $169 is attributable to the annualized non-labor capital 

costs. This estimate is based on a repayment period of 10 years and an interest rate of 7 

percent. The annual and reoccurring costs as shown in Attachment 1 amount to a burden 

cost of $7,543 per year. The total annual burden cost is estimated at $9,983 per year per 

affected source, i.e., $2,440 plus $7,543. 

Existing true minor sources are expected to incur one-time registration costs, and existing 

synthetic minor sources are expected to incur one-time permitting costs during the first 

12 months following rule promulgation. New and modified true minor sources during the 

first 18 months after promulgation are expected to incur one-time registration costs.
18

(c) Estimating Agency Burden and Cost.

The only costs that the federal government will incur as a result of this action are user 

costs associated with the analysis of the reported information, as presented in Attachment 

2. This action imposes no direct burden on state, local, or tribal agencies. However, 

should a tribal agency choose to accept delegated authority for the minor NSR rule, the 

only costs that the tribal agency or government will incur are user costs associated with 

the analysis of the reported information, as presented in Attachment 2. 

Labor rates and associated costs for the Agency are assumed to be the same as the 

respondent's hourly rates rather than the U.S. Government labor rates and associated 

costs, such as those based on labor rates from the U.S. Office of Personnel Management 

(OPM). These rates are considered more appropriate, assuming tribal agencies may 

adopt the rules. Therefore, Agency labor rates are estimated as follows: technical at $65, 

management and legal at $114, and clerical at $49. The occurrence of Agency-related 

activities is based on the same frequency of occurrence as used for respondent activities. 

The average total Agency burden per affected source, provided in Attachment 2, is 42 

hours per affected source including technical, management, legal, and clerical hours. 

The average total annual cost to the Agency per affected source is calculated by 

determining the total labor cost for all the various respondent activities. The costs for 

those activities are then added to any associated costs (e.g., total travel expenses for 

inspections attended) to get the average Agency burden per facility per year. Because the 

Agency activities are similar for processing a permit for a major or minor source, and 

because we anticipate only one new major source in a nonattainment area per year for the 

first 3 years following promulgation, the cost to the Agency for each affected source is 

assumed to be the same. The average total annual cost to the Agency per affected source 

(new majors, new minors, and modifications), given in Attachment 2, including the cost 

of labor, materials, operation, and maintenance, is $3,037 per year. The average total cost 

to the Agency per affected existing synthetic minor source is $693 and per true existing 

minor source is $180.

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

Stationary sources subject to permitting under this rulemaking will be required to file a 

NSR construction permit and provide the various one-time notifications required by the 

rules. In addition, some of these minor sources will be required to install required 

monitoring equipment; conduct air impacts modeling if required by the reviewing 

authority; and provide the various notifications and reports on a routine basis. Costs also 

will be incurred for inspections of control devices. Details on the number and percentage 

of respondents affected by each individual burden activity/item are provided in the 

assumptions listed below in Section 7. The weighted average total burden per affected 

source, including technical, management, legal, and clerical hours, provided in 

Attachment 1 is 286 hours for new/modified minor sources beginning 18 months after the 

effective date of the rule; 342 hours for new/modified major sources in nonattainment 

areas; 65 hours for existing synthetic minor sources; and 5 hours for existing true minor 

sources and new/modified minor sources for the first 18 months. The weighted average 

total annualized cost per affected source (total of reoccurring costs and annualized capitol 

costs) given in Attachment 1, including the cost of labor, capital, materials, and operation 
19

and maintenance, is $9,435 per year for new and modified minor sources after the first 18 

months, and $9,983 per year for new and modified major sources in nonattainment areas.

EPA estimates that 3,803 new minor sources of varying types will be constructed in 

Indian country during the first 3 years after promulgation (1,268 per year). It is estimated 

that 492 existing minor sources will require permits as a result of minor modifications 

during the first 3 years (164 per year). EPA estimates that, at most, three new major 

sources will locate in a nonattainment area in Indian country and that there will be six 

minor modifications to major sources in Indian country (two per year) during the first 3 

years following promulgation. In addition, EPA expects no major modifications in 

nonattainment areas in Indian country during the first 3 years following promulgation. 

Twenty-four new synthetic minors are expected to be processed under the rule during the 

3 years following promulgation. The nationwide total annual recordkeeping and 

reporting burden hours and costs for the first 3 years following promulgation are shown 

in Tables 2 and 3.

(e) Bottom-line Burden Hours and Cost Tables.

(i) Respondent tally.

The bottom-line respondent burden capital costs presented in Table 1 are calculated by 

taking the capital costs for the one-time monitoring, compliance testing, and 

recordkeeping, and the reporting costs associated with the minor-source NSR permit 

program for each affected source type and then multiplying that value by the number of 

affected sources of that type that are expected to occur in Indian country for the first 3 

years following promulgation of the rule. The totals for each source type are then added 

to get the nationwide total capital costs shown in Table 1. Total capital costs for 3 years 

are $44,511,860 (an average cost of $14,837,287 per year). These values include the 

total non-labor capital costs of $3,800,499.

The nationwide total annual compliance costs are the annualized costs of monitoring, 

testing, recordkeeping, and reporting associated with the NSR rule, multiplied by the 

number of affected source types that are expected to occur in Indian country for the first 3 

years following promulgation of the rule. The totals for each source type are then added 

to get the nationwide total annual recordkeeping and reporting burden costs shown in 

Table 2. The total cost for the first 3 years is $22,800,619 (an average cost of $7,600,206 

per year). These values include the total annualized non-labor capital costs of $556,977 

over the 3-year period, which is the product of the annualized non-labor costs per source 

and the total number of affected sources per year.

(ii) The Agency tally.

The bottom-line Agency total annual burden costs are calculated by taking the average 

cost to the Agency per facility ($4,932) and multiplying by the number of affected 

sources in Indian country during the first 3 years following promulgation. The nationwide 

total annual cost to EPA or the tribal agencies, as shown in Table 3, is $17,118,459 for 

the first 3 years (an average cost of $5,706,153 per year).
20

(iii) Variations in the annual bottom line.

Litigation. Although not typically included directly in EPA burden estimates, it is 

possible that EPA or the tribal agencies will be involved in periodic litigation related to 

the minor-source NSR permit program. To characterize these costs, it is assumed that a 

tribal agency will be involved with a facility litigation, on average, of once every 3 years. 

The estimated annual cost of these activities, as shown in Attachment 2, is 73 hours, and 

$5,887 per year per tribal agency litigation.

(f) Reasons for Change in Burden. 

This is a revision of a currently approved base NSR collection ICR.

(g) Burden Statement.

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

is estimated to average 286 hours per respondent for new/modified minor sources after 

the first 18 months following promulgation; 342 hours for new and modified major 

sources in nonattainment areas; 65 hours per respondent for existing synthetic minor 

sources; and 5 hours per respondent for existing true minor sources and for new and 

modified minor sources during the first 18 months following promulgation. 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.

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-OAR-2003-0076, which is available for online viewing at 

www.regulations.gov, or in person viewing at the EPA’s Air and Radiation Docket and

7. Assumptions Made in Estimating the Burden and Cost to the Facilities 

(Respondents) and EPA and Tribal Agencies. 

The burden and cost estimates are based on the following assumptions for those facilities 

requiring NSR permits under the rule. These assumptions are the result of the final rule 

requirements and EPA’s experience with previous rulemakings and standards.
21

(a) All affected minor and major sources will incur preparation and planning costs.

(b) One in 50 facilities will be required to conduct ambient air modeling. Associated costs 

for an ambient modeling study are estimated at $10,000 per source.

(c) One in 20 facilities will be required to hold a public hearing. Associated costs for the 

public hearing are estimated at $100 for the Agency and a $25 material cost to the source.

(d) One in 5 facilities will make revisions to their permits following submittal.

(e) One in 20 facilities will be required to acquire and install a process parameter monitoring 

system. No continuous emission monitoring devices are required or anticipated; it is 

expected that existing process parameter monitoring data will be used to demonstrate 

continuous compliance.

(f) One in 50 facilities will be required to conduct a control-device performance test. 

(g) One in 10 facilities will report at least one deviation from the established monitoring 

values during the year.

(h) Three in 10 facilities will include minor sources that are exempt from the control 

requirements.

(i) All facilities will be required to keep records of some type and to periodically enter data 

into the files.

(j) One in 10 facilities will train personnel and conduct audits of their source during the year.

(k) One in 10 facilities is inspected by the Agency annually, and 10 percent of the inspected 

facilities are found in non-compliance with one or more provisions of the rule. Agency 

travel costs are included in the associated costs at $100 per inspection.

(l) Each tribal agency may be involved in litigation of a facility on average of one per 3 

years.

(m) Associated material costs of $25 are included for each report and plan required for the 

source.

Totals 37,299 $3,800,499 $44,511,860

Notes: 

a New minor sources and modifications to minor sources in the first 18 months following the effective date of the rule are subject to one-time registration only. New minor 

sources and modifications to minor sources after the first 18 months are required to obtain an NSR permit. Therefore, the costs for these source types are different for the first 

and second 18-month period of the first 3 years following promulgation. b The capital costs and cost of one-time activities (i.e., the sum of all one-time costs shown in Attachment 1) are $13,290 for all new and modified sources except new and 

modified sources in the first 18 months after the effective date of the rule and new major sources in nonattainment areas and major modifications to major sources in 

nonattainment areas. Annualized based on a repayment period of 10 years and an interest rate of 7 percent, the amount is $1,892. 

The capital costs and cost of one-time activities for new major sources in nonattainment areas and major modifications to major sources in nonattainment areas are $17,138. 

Annualized based on a repayment period of 10 years and an interest rate of 7 percent, the amount is $2,440. 

These values include the non-labor capital costs ($1,340 or $1,185), shown above.

existing minor sources, and existing synthetic minor sources) are only attributed hours for 1 year. For the remaining affected sources, hours per year were multiplied by 3 years. b Sum of total reoccurring costs from Attachment 1 and the annualized non-labor cost (see note c). c The associated non-labor capital costs for one-time and reoccurring activities for most new and modified sources is $1,340 per year. Annualized based on a repayment period of 

10 years and an interest rate of 7 percent, the amount is $191. 

The associated non-labor capital costs for one-time and reoccurring activities for new major sources in nonattainment areas and major modifications to major sources in 

nonattainment areas is $1,185 per year. Annualized based on a repayment period of 10 years and an interest rate of 7 percent, the amount is $169.
