The NO2/NOx In-Stack Ratio: At the Intersection of NAAQS Modeling,

Permitting, and Compliance

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.

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?

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

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.

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
