Instructions for Requesting Coverage under the General Air Quality Permit 

for New or Modified True Minor Source Boilers in Indian Country

Version 1.0

Last Modified: July 2, 2014

If you wish to apply for the ‘General Air Quality Permit for New or Modified True Minor Source Boilers,’ 

please complete the form “Request for Coverage under the General Air Quality Permit for New or Modified 

True Minor Source Boilers in Indian Country.”

This General Air Quality Permit implements the requirements of the minor New Source Review (NSR) rule as 

described under 40 CFR part 49.

These instructions are intended to provide you with information that may be useful in completing the Request 

for Coverage form. In the form, please provide information on all existing, new and modified units.

Helpful Definitions from the Federal Indian Country Minor NSR Rule (40 CFR 49.152) –

This is not a comprehensive list.

 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. [40 CFR 49.152(d)]

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.

 Potential to emit (PTE) means the maximum capacity of a source to emit a pollutant under its physical 

and operational design. Any physical or operational limitation on the capacity of the source to emit a 

pollutant, including air pollution control equipment and restrictions on hours of operation or on the type 

or amount of material combusted, stored or processed, shall be treated as part of its design if the 

limitation or the effect it would have on emissions is enforceable as a practical matter. Secondary 

emissions, as defined at 40 CFR 52.21(b)(18) of this chapter, do not count in determining the PTE of a 

source.

Section 2: Facility Information for Requesting Coverage under the General Air Quality 

Permit for New or Modified True Minor Source Boilers

12. Description of Your Boiler: Is your boiler a new facility or a modification to an existing facility? If this is a 

new request, describe the proposed new source. If this is a modification, describe the modification 

proposed. 

13. North American Industry Classification System (NAICS)/Standard Industrial Classification (SIC) Code and 

Description: Provide the NAICS/SIC Code and/or a description for the facility:

 11**** NAICS Agriculture, Greenhouses

 2211** NAICS Electric Power Generation

 82** SIC Educational Services

 Other – please specify _____NAICS; _____SIC

14. Ozone Attainment Status: Indicate if this facility is located in an ozone nonattainment area and specify 

the classification of the ozone nonattainment area. If part of a tribe’s area is designated as attainment, 

unclassifiable, or attainment/unclassifiable and another part as nonattainment, the answer to this 

question should be based on the designation where the source would be located. If the source straddles 

the two areas, the more stringent classification applies. Information on the ozone attainment status of 

the area where your facility is located can be found at: http://www.epa.gov/airquality/greenbook/. 

Please contact your reviewing authority if you have questions about an area’s attainment status.

15. Exemption from the Minor NSR Program: For a new facility, calculate the PTE of all proposed emission 

units and determine if the proposed construction is below the applicability thresholds in the Indian 

Country Minor NSR program (the thresholds listed in 40 CFR 49.153). For a modification to your existing 

facility, calculate the emissions increase from your new or modified emission units and determine if the 

proposed construction or modification is below the thresholds listed. For a new emissions unit, the 

emissions change is the PTE of the new unit. For a modified emissions units, the emissions change is the 

change in allowable emissions of the unit. 

You only need to consider the thresholds for nonattainment areas if your source is (will be) located in an 

area designated nonattainment. If in a nonattainment area, then you only need to consider the 

nonattainment threshold for the pollutant(s) for which the area is designated nonattainment. 

If the PTE of your new facility or the emissions increase at your existing facility is below the applicable 

thresholds listed for ALL pollutants, the new or modified source is exempt from the minor NSR program. 

You do not need a permit for this source. The U.S. Environmental Protection Agency (EPA) is providing a 

PTE calculator to assist with this task. The calculator is available online at:

http://www.epa.gov/air/tribal/tribalnsr.html.

16. Qualification for General Permit – Facility in Attainment, Unclassifiable, or Attainment/Unclassifiable

Area: If located in an attainment, unclassifiable, or attainment/unclassifiable area, calculate the PTE of 

your entire facility (include new, modified, and existing units) and determine if the facility is below the 

NSR major source threshold of 250 tons per year (tpy). If the PTE of the proposed facility is equal or 

above 250 tpy for ANY pollutant, this new or modified source does not qualify for this general permit. 

The EPA is providing a PTE calculator to assist with this task. The calculator is available online at:

http://www.epa.gov/air/tribal/tribalnsr.html.

17. Qualification for General Permit – Facility in Nonattainment Area: If located in a nonattainment area, 

calculate the PTE of your entire facility (include new, modified, and existing units) and determine if the 

facility is below the NSR major source thresholds listed. Note the NSR major source classification is 

pollutant specific. You only need to consider the nonattainment area thresholds for the particular 

pollutant for which your area is designated as nonattainment. If the PTE of the proposed facility is equal 

to or above the threshold for ANY pollutant for which the area is designated as nonattainment then this 

new or modified source does not qualify for this general permit. The EPA is providing a PTE calculator to 

assist with this task. The calculator is available online at: http://www.epa.gov/air/tribal/tribalnsr.html.

18. Qualification for General Permit – Hazardous Air Pollutants: Calculate the PTE of your entire facility 

(include new, modified, and existing units) and determine if the facility is below the major source 

thresholds for hazardous air pollutants (HAPs). If the PTE of the proposed facility is equal to or above 10 

tpy for a single HAP or 25 tpy for any combination of HAPs, then this new or modified source does not 

qualify for this general permit. The EPA is providing a PTE calculator to assist with this task. The 

calculator is available online at: http://www.epa.gov/air/tribal/tribalnsr.html.

19. Setback Requirement: The permit contains a setback requirement and this question seeks information 

to verify compliance with that requirement.

Section 3: Technical Information for Requesting Coverage under the General Air Quality 

Permit for New or Modified True Minor Source Boilers

20. Boilers and Heaters: List all boilers and heaters at the source, including the ID#; unit description, fuel 

type(s), maximum rated capacity in million British thermal units, make/model; and date of construction. 

For the unit description, identify whether the equipment is a boiler or process heater and whether it is 

new, modified, or existing. The definition for boiler and process heater can be found in Attachment B of 

the General Air Quality Permit for New or Modified True Minor Source Boilers.

21. Emergency Engines: Provide information on the ID#, unit description, maximum rated capacity, types of 

fuel used, date of manufacture, and model year.

22. Volatile Liquid Storage Tanks: Technical information is needed concerning onsite storage of liquids, 

including unit ID#, type of liquid stored, tank capacity, vapor pressure of liquid, whether the tank is 

above or below ground and date of installation (if an existing unit).
