Useful Areas of Expertise
Air pollution modeling Air pollution control
– Equipment – Practices
Law

Typical Permit Format
General source identification Source location Emissions information Control technology analysis - BACT
– Top-down approach
Air Quality Impact Analysis

General Source Information
Name Source classification –
– On list to count fugitive emissions?
Generally what construction/modification is being proposed – Reason for construction
![Page 6: PSD Permitting Process](https://reader036.vdocuments.us/reader036/viewer/2022081506/568150f8550346895dbf1725/html5/thumbnails/6.jpg)
6
Source ID–what to look for
Is source classification correct? Does reason for modification make sense?
![Page 7: PSD Permitting Process](https://reader036.vdocuments.us/reader036/viewer/2022081506/568150f8550346895dbf1725/html5/thumbnails/7.jpg)
7
Source Location
Location – Attainment/nonattainment area– Nearby class I areas
Source site diagram
![Page 8: PSD Permitting Process](https://reader036.vdocuments.us/reader036/viewer/2022081506/568150f8550346895dbf1725/html5/thumbnails/8.jpg)
8
Source location–what to look for
Is location accurate? Does permit ID all Class I areas and tribal
lands within 100 KM? Does it ID all nearby nonattainment areas? Does site diagram clearly explain what is
being proposed? Unexplained buildings in diagram?

Emissions Data
Existing emissions baseline Change in emissions
– Netting calculation, if any
Stack height
![Page 10: PSD Permitting Process](https://reader036.vdocuments.us/reader036/viewer/2022081506/568150f8550346895dbf1725/html5/thumbnails/10.jpg)
10
Emissions Data–what to look for
What method is used to measure emissions? – Stack tests – when, how often?– Correct emission factors?– Do assumptions make sense? – Is baseline year the correct year? – Is averaging done correctly?
Is calculation for the emissions change clearly shown and explained?
Is stack height measured correctly?

Air Quality Impact Analysis
Terrain Model name Features selected Results
– Increment– NAAQS– Class I areas
![Page 12: PSD Permitting Process](https://reader036.vdocuments.us/reader036/viewer/2022081506/568150f8550346895dbf1725/html5/thumbnails/12.jpg)
12
Modeling–what to look for
All important terrain features identified? Correct model being used?
– Pollutants – sources Assumptions reasonable? Correct meteorological data set being used? All results presented, or only summaries?
![Page 13: PSD Permitting Process](https://reader036.vdocuments.us/reader036/viewer/2022081506/568150f8550346895dbf1725/html5/thumbnails/13.jpg)
13
More modeling things to look for
Increment analyses done correctly?– Baseline area?– All relevant pollutants – Any increment violations?
Do emission increases cause new NAAQS violations?
Do emissions impact existing nonattainment areas?– Impacts mitigated?

14
Control technology
Proposed Best Available Control Technology (BACT) – Top-down approach
Describe other alternatives For each relevant pollutant
![Page 15: PSD Permitting Process](https://reader036.vdocuments.us/reader036/viewer/2022081506/568150f8550346895dbf1725/html5/thumbnails/15.jpg)
15
Control Technology–what to look for
Reasons for not choosing best technology? Technology from BACT/LAER
Clearinghouse? Technology for all relevant pollutants?

Public Participation/Notice
Date, time documentation Notice in readily available local newspaper Contacted Relevant Federal Land Managers Contacted nearby tribes
![Page 17: PSD Permitting Process](https://reader036.vdocuments.us/reader036/viewer/2022081506/568150f8550346895dbf1725/html5/thumbnails/17.jpg)
17
Public comment–what to look for
All FLM concerns addressed? Public notice clear and well publicized? Any public comments? Public comments adequately addressed?
![Page 18: PSD Permitting Process](https://reader036.vdocuments.us/reader036/viewer/2022081506/568150f8550346895dbf1725/html5/thumbnails/18.jpg)
18
Were formalities met?
Did source submit permit application before commencing construction?
Has the state been working with source? Permit easy to follow?

How to submit comments
States must send copy of permit to tribal governing body
Public-comment period Can request public hearing and provide
verbal comments Special Class I protection
– Lower increment allowed– Visibility
