## Questionnaire for Requesting Coverage under the General Air Quality Permit for New or Modified True Minor Source Compression Ignition Engines in Indian Country

Last Modified: July 2

Version 1. 0



### Do the General Permit s apply to my facility?

Th is questionnaire is intended to help you, the facility owner or operator, determine you r eligib i l ity for a General Air Quality Permit for New or Modified Minor Source Compression Ignition Engines

. The U.S. Environmental Protection Agency is making two engine permits available: one for non

- emergency compression ignition internal combustion engines and one for non

- emergency spark ignition engines. The permits are designed to be used with one type of non

emergency engine, either spark ignition OR compression ignition. This questionnaire only applies to sources with non

emergency compression ignition engines. If you have both compression ignition AND spark ignition non

- emergency engines present at your facility, then you are not eligible for this permit and should consult your reviewing authority about seeking a site

- specific permit. However, the permits can accommodate emergency engines of either type that may be present at your facility.

If you have a true minor source of engines with spark ignition non

- emergency engines, see the document Questionnaire: Spark Ignition Engines. If you have a true minor source of boilers and emergency engines you should consider the General Air Quality Permi t for New or Modified Minor Source Boilers (see the Questionnaire: Boilers).

You are not required to complete this questionnaire and th is questionnaire is not necessary to apply for a General Air Quality Permit for Minor Source of Compression Ignition Eng ines

. This questionnaire does not cover all of the General Air Quality Permit requirements and does not guarantee approval of a minor source preconstruction permit under this

program

.



### Description of Engines Engines included in this source category are stationary internal combustion engines (ICE)

– spark ignition and compression ignition

– that convert heat energy into mechanical work and are not mobile. This source category does not include combustion turbines or nonroad engines (mobile ICE) such a s forklifts, off

- highway mobile cranes, bulldozers, and lawnmowers. Stationary ICE includes reciprocating ICE, rotary ICE, and other ICE, except combustion turbines as
noted above. Th is category covers both non

- emergency and emergency stationary ICE.



### About this Questionnaire The questions focus on general information pertaining to your existing or future engine s . The questionnaire is not meant to be exhaustive and only requires knowledge of basic facility information, including the maximum capacity of

the units and the type of units being employed

.



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

 Plan t o construct, relocat e or modify a true minor source of engine s within Indian country ;

 Have a potential to emit (PTE) less than the New Source Review (NSR) major source thresholds and equal to or above the minor NSR applicability thresholds. See the “Does my engine need or qualify for a minor source permit?” section below ;

 Are not located in a severe or extreme ozone nonattainment area ;

 Are located in an ozone attainment, unclassifiable, attainment /unclassifiable area, marginal ozone nonattainment area, or mo derate ozone nonattainment area and can meet one of t wo options:Questionnaire: Compression Ignition Engines Page 2 of 6

Version 1.0 o Option 1: All non

- emergency engines are compression

- emergency compressi on ignition engines is no greater than 3800 hp; the combined maximum engine power of all emergency engines is no greater than 1000 hp ; or

o Option 2: The combined maximum engine power of all non

- emergency compression ignition engines is no greater than 1900 hp and t he combined maximum engine power of all emergency engines is no

grea ter than 2500 hp;

emergency compression ignition engines that is no greater than 1 100 hp and have a combined maximum engine

power from all emergency engines that is no greater than 750 hp;

 H ave auxiliary heaters that only burn natural gas and have a combined maximum heat input of no greater than

10 million British thermal units ( M MBtu ) /h ou r (hr) ;

 Do not know whether your facility needs a permit, or do not know the attainment status of your area and want to find out whether or not you should apply for a general air quality permit or a major source permit
for a n engine ; 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 Quality Permit
for New or Modified True Minor Source Graphic Arts and Printing Operations

## Questionnaire for Compression Ignition Engines

Part 1: Do my Engine s Need a True Minor Source Permit? The following questions are meant to determine whether or not your engines need 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 ) , nitrogen 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.html

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

. Do not include mobile engines or engines that remain in one location for less than 12 months.

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

- specific permit. If you answered ‘Yes

, ’ continue on to the next question

.

2. Is the PTE of your new facility or the emissions increase from your modified existing facility equal to or above the applicable minor NSR thresholds listed below for ANY of the seven pollutant s listed in the table below ? The emissions from your facility may be calculated using the PTE calculator provided at http://www.epa.gov/air/tribal/tribalnsr.html .

### P art 2: What types of facilities DO NOT Qualify for Coverage under this General Air Quality Permit

for New or Modified Minor Source Compression Ignition Engines ?
The following question is meant to determine whether or not your engines source would be disqualif ied f rom

coverage under the General Air Quality Permit for New or Modified Minor Source Compression Ignition Engines

.

1. Do you intend to install non

- emergency spark ignition engines (e.g. engines that burn natural gas, liquified petroleum gas, or gasoline) at your new or existing source ?

Yes No No t Applicable

If yo u answered ‘No’ to this question, your facility may qualify for coverage under the General Air Quality Permit
for New or Modified Minor Source Compression Ignition Engines

, and should continue on to Part 3 of the
Questionnaire

.

If you answered ‘Yes’ to this question, your facility likely does not qualify for coverage under the General Air Quality Permit for New or Modified Minor Source Compression Ignition Engines and you should consider whether you quali f y for the General Air Quality Permit for New or Modified Minor Source Compression Ignition Engines

. If you have both non

- emergency compression ignition engines and non

- emergency spar k ignition engines, then you must obtain a site

- specific permit.Questionnaire: Compression Ignition Engines Page 5 of 6

### Conclusion If you answered ‘Yes’ or ‘Not Applicable’ to each question in Part 3 , your facility may qualify for coverage under the General Air Quality Permit for New or Modified Minor Source Compression Ignition Engines

. If you believe based upon your answers in this questionnaire that your new or modified engine qualifies for a Gener al Air Quality Permit
for New or Modified Minor Source Compression Ignition Engines , please contact your reviewing authority to obtain a permit application

.

If you answered ‘No’ to any of these questions, your facility may not qualify for coverage under t he General Air Quality Permit for New or Modified Minor Source Compression Ignition Engines . Please contact your reviewing authority to confirm that your facility will not qualify for this general permit
