Instructions

(Please do not include a copy of these instructions in the application you submit to us.)

Use of This Form

•

Proposed new construction or modifications should first be evaluated to determine if the change is

major under the major NSR program using the procedures at 40 CFR 52.21 (i.e., baseline actual to

projected actual applicability test). If the proposed construction does not qualify as a major under

that test, then it may be subject to the requirements of the minor NSR rule at 40 CFR 49.151.

Helpful Definitions from the Federal Minor NSR Rule (40 CFR 49) – This is not a comprehensive list.

•

40 CFR 49.152(d) - Modification means any physical or operational change at a source

that would cause an increase in the allowable emissions of the affected emissions units

for any regulated NSR pollutant or that would cause the emission of any regulated NSR

pollutant not previously emitted.

The following exemptions apply:

(1) A physical or operational change does not include routine maintenance, repair, or replacement.

(2) An increase in the hours of operation or in the production rate is not considered an operational

change unless such increase is prohibited under any federally-enforceable permit condition or

other permit condition that is enforceable as a practical matter.

(3) A change in ownership at a source is not considered a modification.

•

40 CFR 49.152(d) - Allowable emissions means ‘‘allowable emissions’’ as defined in §52.21(b)(16),

except that the allowable emissions for any emissions unit are calculated considering any emission limitations

that are enforceable as a practical matter on the emissions unit’s potential to emit.

•

52.21(b)(16) - Allowable emissions means the emissions rate of a stationary source calculated using

the maximum rated capacity of the source (unless the source is subject to federally enforceable limits

which restrict the operating rate, or hours of operation, or both) and the most stringent of the

following:

(i) The applicable standards as set forth in 40 CFR parts 60 and 61;

(ii) The applicable State Implementation Plan emissions limitation, including those with a future

compliance date; or

(iii) The emissions rate specified as a federally enforceable permit condition, including those with a

future compliance date.

Page 10 of 15

(H2S), total reduced sulfur (TRS) and reduced sulfur compounds, including all calculations for the

estimates.

1. These estimates are to be made for each emission unit, emission generating

activity, in addition to total emissions.

2. The information should include all of the supporting calculations,

assumptions and references. Emission estimates must address all

emission units and pollutants proposed and/or affected by the limitation

and be presented in short term (e.g. pounds per hour) as well as annual

(tons per year) units.

3. Any emission estimates submitted to the Regional Administrator must

be verifiable using currently accepted engineering criteria. The

following procedures are generally acceptable for estimating

emissions from air pollution sources:

•

•

•

•

•

Unit-specific emission tests;

Mass balance calculations;

Published, verifiable emission factors that are applicable to the source (i.e. manufacturer

specifications);

Other engineering calculations; or

Other procedures to estimate emissions specifically approved by the Regional

Administrator.

4. Guidance for estimating emissions can be found at https://www.epa.gov/air-emissions-factorsand-quantification.

Current Actual Emissions: Current actual emissions for a pollutant is expressed in tpy and generally

is calculated by multiplying the actual hourly emissions rate in pounds per hour (lbs/hr) times actual

hours operated (which is the number of hours in a year) and dividing by 2,000 (which is the number

of pounds in a ton).

For an existing air pollution source (permitted and unpermitted) that operated prior to the

application submittal, the current actual emissions are the actual rate of emissions for the

preceding calendar year and must be calculated using the actual operating hours, production

rates, in-place control equipment, and types of materials processed, stored, or combusted during

the preceding calendar year. The emission estimates must be based upon actual test data or, in

the absence of such data, upon procedures acceptable to the Regional Administrator.

Current Allowable Emissions: Current allowable emissions for a pollutant is expressed in tpy and

generally is calculated by multiplying the allowed hourly emissions rate in pounds per hour (lbs/hr)

times allowed hours (which is the number of hours in a year) and dividing by 2,000 (which is the

number of pounds in a ton).

1. “Allowed” means the source is restricted by permit conditions that limit its emissions and are

enforceable as a practical matter (i.e., allowable emissions). The allowable emissions for any

Page 11 of 15

emissions unit are calculated considering any emissions limitations that are enforceable as a

practical matter on the unit’s PTE.

2. For an existing permitted air pollution source that operated prior to the application submittal, the

current allowable emissions are the allowable rate of emissions for the preceding calendar year and

must be calculated using the permitted operating hours, production rates, in-place control equipment,

and types of materials processed, stored, or combusted during the preceding calendar year.

3. For an existing air pollution source that does not have an established allowable emissions

level prior to the modification must report the pre-change uncontrolled emissions.

Post-Change Potential Emissions (Potential uncontrolled emissions from proposed project): This is

the maximum capacity of a source to emit a pollutant under its physical and operational design.

This is expressed in tpy and generally is calculated by multiplying the maximum hourly emissions

rate in pounds per hour (lbs/hr) times 8,760 hours (which is the number of hours in a year) and

dividing by 2,000 (which is the number of pounds in a ton).

Post-Change Allowable Emissions: A source’s allowable emissions for a pollutant is expressed in

tpy and generally is calculated by multiplying the allowed hourly emissions rate in pounds per hour

(lbs/hr) times allowed hours (which is the number of hours in a year) and dividing by 2,000 (which

is the number of pounds in a ton).

1. Unless the source is restricted by permit conditions or other requirements that are enforceable

as a practical matter, the post-change allowable emissions would be equivalent to postchange uncontrolled emissions. For the post-change allowable emissions a lower level of

allowable emissions may be proposed.

2. For physical or operational changes at minor sources and for minor physical or operational

changes at major sources, the total increase in allowable emissions resulting from your

proposed change would be the sum of following:

•

For each new emissions unit that is to be added, the emissions increase would be the

potential to emit of each unit.

•

For each emissions unit with an allowable emissions limit that is to be changed or

replaced, the emissions increase would be the allowable emissions of the emissions unit

after the change or replacement minus the allowable emissions prior to the change or

replacement. However, this may not be a negative value. If the allowable emissions of

an emissions unit would be reduced as a result of the change or replacement, use zero in

the calculation.

•

For each unpermitted emissions unit (i.e., a unit without any emissions limitations

before the change) that is to be changed or replaced, the emissions increase would be the

allowable emissions of the unit after the change or replacement minus the potential to

emit prior to the change or replacement. However, this may not be a negative value. If

the allowable emissions of an emissions unit would be reduced as a result of the change

or replacement, use zero in the calculation.

 Air Quality Review

Qualitative Air Quality Assessment

Provide a narrative description of the current air quality conditions and the expected impact the

permitted source would have on that air quality. Factors to include in the qualitative discussion are

meteorology, terrain, elevation, distance to ambient air, expected emissions, stack heights, etc. Your

reviewing authority may require you to provide additional information used to determine impacts

that may result from your new source or modification.

Do I need to do a modeling analysis?

If there is reason to be concerned that new construction would cause or contribute to a National

Ambient Air Quality Standard (NAAQS) or Prevention of Significant Deterioration (PSD) increment

violation, you may be required to conduct and submit an Air Quality Impact Analysis (AQIA)

consistent with the requirements and recommendations of the Guideline on Air Quality Models

(Appendix W to 40 CFR Part 51). In addition, if the AQIA reveals that the new construction could

cause or contribute to a NAAQS or PSD increment violation, such impacts must be reduced before a

pre-construction permit can be issued.

To facilitate the protection of the NAAQS and PSD Increment, EPA requests that those proposed

activities that meet the following criteria perform an AQIA:

1. The proposed activity has air emissions that the Reviewing Authority determines has the

potential to cause adverse air quality effects for which an air quality impact analysis is

necessary for an accurate assessment of the environmental impact of the activities proposed.

2. Modeling of proposed emissions is usually warranted, even though the proposed activity does

not meet the modeling requirements, above, if it is reasonable to believe the new activity may

cause or contribute to a violation of applicable ambient air quality standards or increments in

circumstances such as:

(a) A substantial portion of the new or modified emissions have poor dispersion

characteristics (e.g., rain caps, horizontal stacks, fugitive releases, or building

downwash) in close proximity to ambient air at the site boundary;

(b) The new or modified emissions are located in complex terrain (e.g., terrain above stack

height in close proximity to the source); or

(c) The new or modified emissions are located in areas with existing air quality concerns.

(d) If you have questions about whether modeling may be necessary based on the criteria

above, please contact the Reviewing Authority:

OMB Control No. 2060-0003

Approval expires 01/31/2023

What Kind of Air Quality Modeling Analysis (AQIA) Is Needed?

1. EPA considers a stepped or phased approach to modeling to be appropriate, as follows:

Step 1: Screening Analysis

Step 2: Single-Source Impact Analysis, per Appendix W, Section 9.2.3.a.i.

Step 3: Cumulative Impact Analysis, per Appendix W, Section 9.2.3.a.ii.

Step 4: PSD Increment and NAAQS Analysis

Step 6: Additional Impact Analysis

2. Step 1: Screening Analysis

For proposed new or modified sources that meet the modeling requirement criteria identified

above, protection of air quality from proposed emissions may be shown by using a simple

screening technique (e.g., AERSCREEN). Screening models are available for download at the

EPA SCRAM website: https://www.epa.gov/scram/air-quality-dispersion-modeling-screeningmodels. A pre-approved modeling protocol is not necessary prior to conducting a Screening

Analysis.

3. If the proposed new or modified emission increases do not increase ambient concentrations of a

pollutant by more than the significant impact levels (SILs), as compared to the SILs identified

below, no further modeling is necessary.

Note: The Class I area SILs are provided as guidance and have not been formalized by EPA.

4. Sources that cannot demonstrate protection of air quality using a screening technique should

continue to the modeling requirements in Step 2 through Step 5. Modeling in Steps 2 through 5

should be performed based an approved protocol and consistent with the requirements and

recommendations of the Guideline on Air Quality Models (Appendix W to 40 CFR Part 51).

5. Applicants are encouraged to contact the Reviewing Authority prior to conducting any refined

modeling analysis (Step 2 through Step 5) to obtain an approved modeling protocol.

Page 14 of 15

What Should I Include in My Application if Modeling Is Necessary?

1. Approved Modeling Protocol

In order to expedite the permitting process, it is recommended that you include a protocol that

has already been approved. An application will not be deemed complete until the protocol has

been approved.

2. Modeling Results

In all cases, the modeling results should include the name of the model used, all input

parameters, and the resulting output. Electronic copies of the modeling input/output files should

be provided to the Reviewing Authority.
