The NO2/NOx In-Stack Ratio: At the Intersection of NAAQS Modeling,
Permitting, and Compliance
for the:
Presented by:
Shirley F. Rivera Resource Catalysts
NAAQS Modeling
Compliance
Permitting
At the intersection… (pt. 1)
PATIENCE and HARD WORK! You TIMELY received a DRAFT permit
to construct with the conditions you WANTED, completing the Tier 3, 1-hour NO2 NAAQS modeling, even with a significant impact where (if required) you modeled NEARBY sources.
At the intersection… (pt. 2)
CONGRATS! You TIMELY received a FINAL permit
to construct with the conditions you WANTED, after the agency successfully responded to PUBLIC COMMENTS and there were NO appeals.

About me
Presentation Overview
…will not address details of 1-hour NO2 modeling and
guidance interpretation details of emissions measurement,
testing, test process considerations recommended permit conditions recommended ISRs
Presentation Overview
…will address EPA efforts for a national database April 2013 R/S/L Modelers Workshop

Audience check
What’s the right ISR?
IMPROV warm-up Yell out your first name
I am holding something in my hand that is … What is it?
I am thinking of a number between 0 and 0.49 … What is it?
Sample of ISRs
GT SU/SD
GT norm
RICE
Boilers
0.10 0.50 - -> 0.50
EPA GTs EPA Diesel Eng
0.20 0.30 0.40
CAPCOA
Take Away, Call to Action POPULATE the EPA database
COLLECTIVE cross-communicate within and among - – Agencies, Businesses, Consultants, Test Firms – Equipment manufacturers / representatives
START at the “Source” – Stationary source, source test results – Source test firms – Manufacturer Information
NAAQS Modeling
Compliance
Permitting
What we know
NAAQS Modeling
Modeling protocol
1-hour NAAQS air quality modeling triggered – If Tier 1 and 2 do not work,
Tier 3 is pursued, using default 0.50 or a lower, justified alternative
May need ISRs for nearby sources
Permitting
Pre-application efforts
Application completeness determination
Coordinating with AQ modeler, applicant contact
Permit prep & issue
Compliance
EPA Method 7E for NOx sources
May be equipped with CEMS
Air agency may/may not require ISR demonstration
Permit condition option
April 2013 R/S/L Modelers Workshop

Examples – Projects, Modeling Guidance
Examples
Pio Pico ICE project AZDEQ Modeling Guidelines(Sept 2013) CAPCOA Modeling Guidance (Oct 2011)
additional inspiration
EUEC 2015 Session Suggestions
Pio Pico (June 2012)
Internal Combustion Eng
AZDEQ Modeling Guidelines
September 2013 Hierarchy for ISR selection and
justification – Agency-verified source test data – Literature review/compilation of like-kind
source – Use of default value = 0.50
CAPCOA Modeling Guidance
October 2011 Appendix C – Table of ISRs
– Natural gas-fired: boiler, engine, turbine, dryer, process heater, glass furnace
– ICE: waste gas, biogas, diesel – Trucks/Cars: light, medium, heavy duty
EUEC Session Suggestions
Track A A4. NSR A4.5 – Air Permitting for Small Gas Turbines
Track B B5.3 – GT Regs with focus on CEMS & Part 75 B5.4 – Low level emissions testing with CARB B6. Modeling
“Magic Wand”
“Magic Wand”
NAAQS Modeling
Modeling protocol addresses the approach and resources for ISRs – project and nearby sources (if applicable)
Bonus: Clear agency protocol expectations.
“Magic Wand” Assurance of properly
conducting Method 7E source test for determining ISR
Bonus: Equipment manufacturers provide a range of ISRs. Common agency and/or source approach to data collection.
Compliance
“Magic Wand”
Permitting
Common project organizational approach to air permitting, esp. at the intersection
Bonus: An “AP-42” style of ISRs that complements the EPA database.

0.10 0.50 - -> 0.50 0.20 0.30 0.40
REMINDER: Call to Action POPULATE the EPA database
COLLECTIVE cross-communicate within and among - – Agencies, Businesses, Consultants, Test Firms – Equipment manufacturers / representatives
START at the “Source” – Stationary source, source test results – Source test firms – Manufacturer Information
