## Questionnaire for Requesting Coverage under the General Air Quality Permit for

New or Modified True Minor Source Boilers in Indian Country

Last Modified: July 2 , 2014

Version 1. 0



### Does the General Permit apply to my facility?

The following questionnaire is intended to help you, the facility owner or operator, determine whether or not you are

eligible for a General Air Quality Permit for New or Modified True Minor Source Boilers . You are not required to

complete it and th is questionnaire is not necessary to apply for a General Air Quality Permit for New or Modified True

Minor Source Boilers . This questionnaire does not cover all of the General Air Quality Permit requirements and does not

guarantee approval of a true minor source preconstruction permit under this program

. This source category

– t rue

m inor s ource b oilers

– includes stationary sources with boilers, process heaters and emergency engines.



### Description of Boilers

A b oiler means an enclosed device using controlled flame combustion in which water is heated to recover thermal

energy in the form of steam and/or hot water

. T his Boilers Questionnaire is for stationary sources of boilers , process
heaters, and emergency engines that are not major sources of air pollution and that are located, or planning to locate,

within Indian c ountry

.



### About this Questionnaire

The questions focus on general information pertaining to your existing or future boiler s , process heaters and

emergency engines . The questionnaire is not meant to be exhaustive and only requires knowledge of basic facility

information, including heat input capacity

.



### You should continue with this Questionnaire if you:

 Plan t o construct a new, true minor source boilers within Indian c ountry ;

 Plan t o modify an existing, true minor source boiler located within Indian c ountry ;

 Have a potential to emit (PTE) less than the New Source Review (NSR) major source t hres holds and equal to or

above the minor NSR applicability t hres h olds . See the “Does my Boiler Need or Qualify for a Minor Source

Permit?” section below ;

 Have a PTE less than the major source thresholds for hazardous air pollutants (HAPs). See the “Does my Boiler

Need or Qualify for a Minor Source Permit?” section below ;

 Plan to construct or modify a boiler that , after construction or modification, burns only gaseous or low

- sulfur

( containing no more than 15 parts per million ( ppm ) (0.0015 percent) sulfur) liquid fuels ;

 Have no single boiler with a capacity of 100 milli on British thermal units ( MMBtu ) /h ou r (hr) or greater;

 Do not know whether your facility needs a permit, or if you do not know the attainment status of your area and

want to find out whether or not you should apply for a minor source g eneral air quality permit or a major source

permit for a boiler ; and

 Intend to satisfy the requirements of the Endangered Species Act (ESA) and National Historic Preservation Act

(NHPA) according to the procedures attached to the Request for Coverage under the General Air Qu ality Permit

for New or Modified True Minor Source Boilers

.

## Questionnaire for Boilers

Part 1: Does my Boiler Need a True Minor Source Permit?

The following questions are meant to determine whether or not your boiler needs a true minor source permit

.

1. Is the PTE of your facility less than 250 tons per year (tpy) for particulate matter (PM, PM 10 , or PM 2.5 ), volatile

organic compounds ( VOC ) , nitrog en oxides (NO X ), carbon monoxide (CO), and sulfur dioxide (SO 2 )? The emissions

from your facility may be calculated using the PTE calculator provided at

http://www.epa.gov/air/tribal/tribalnsr.ht ml

. Be sure to include all existing, new, and modified emission units

.

Yes No

If you answered ‘No

, ’ your source does not qualify for the minor NSR program. Please contact your rev iewing

authority to apply for a site

- specific permit. If you answered ‘Yes

, ’ continue on to the next question

.

2. Is your facility a minor source of HAP s ? If the PTE of your facility is less than 10 tons per year for a single HAP and

less than 25 tons per year for any combination of HAPs, your source is a minor source of HAPs. The emissions

from your facility may be calculated using the PTE calculator provided at

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

. Be sure to include all existing, new, and modified emission units.

Yes No

If you answered ‘No,’ your source does not qualify for the minor NSR program. Please contact your reviewing

authority to apply for a site

### Conclusion

If you answered ‘Yes’ or ‘Not Applicable’ to each of the questions in Part 3 , you may qualify for coverage under the

General Air Quality Permit for New or Modified True Minor Source Boiler s

. If you believe based upon your answers in

this questionnaire that your new or modified boiler qualifies for a General Air Quality Permit for New or Modified

True Minor Source Boilers , please contact your reviewing authority to obtain a permit application.

If you answered ‘No’ to any of these questions, your boiler may not qualify for coverage under the General Air

Quality Permit for New or Modified True Minor Source Boiler s . Please contact your reviewing authority to confirm

that your boiler will not qualify for a permit
