for New or Modified True Minor Source Compression Ignition Engines 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 Compression Ignition Engines in Indian Country

, ’ please complete the form “Request for Coverage under the General Air Quality Permit for New or Modified True Minor Source Compression Ignition Engines in Indian Country

. ”

This General Air Quality Permit implements the requirements of the minor New Source Review (NSR) rule as
described under 40 CFR p art 49.

These instructions are inten ded to provide you with information that may be useful in completing the Request for Coverage forms. In the form, please provide information on all existing, new and modified units.



### Helpful Definitions fr o m 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 e mit (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.Instruction s : Compression Ignition Engines Page 2 of 4

### Section 2: Facility Information for Requesting Coverage under the General Air Quality
Permit for New or Modified True Minor Source Compression Ignition Engines

12. Brief Description of Your Project : Is your facility new 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 (check all that apply):

 2211** NAICS Electric Power Generation, Transmission or Distribution  622110 NAICS Medical and Surgical Hospitals  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 asInstruction s : Compression Ignition Engines Page 3 of 4

Version 1.0 attainment, unclassifiable, or attainment /unclassifiable and another part as non attainment, 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 you r 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 Mi nor 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 m odification 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 (or will be) locate d 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 P TE calculator to assist with this task. The calculator is available online at : http://www.epa.gov/air/tribal/tribalnsr.html

.

Do not include mobile engines or engines that remain in one location l ess than 12 months in your
calculation.

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

.

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

17. Qualification for General Permit

– Facility in Nonattainment Area : If located in a nonattainment are a, 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 conside r the nonattainment area thresholds for the particular pollutant s for which your area is designat ed 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
