1. Ozone in the Tri Cities
July 2018

2. Smog – Ground Level Ozone

3. Ozone in the Tri Cities - a brief history:
2013 – AirPact (model) showed potential for high ozone in Kennewick
2014 – Temporary Monitor on Kellogg; mobile monitoring
2015 – Permanent Monitor installed at BCAA offices; additional mobile monitoring
2015 – National Ambient Air Quality Standard for Ozone reduced to 70 ppb from 75 ppb
2016 – Precursor Study
2017 – Precursor Study Completed; Kennewick ozone values continue to be of concern
2018 – Community outreach

4. Areas of the country projected to have ozone issues:
The Tri Cities is not on this map!

5. Local geography is part of the situation:

6. Area of interest: Franklin County Dept. of Ecology Benton County
Nuclear Program
Industrial Unit
Eastern Regional Office
Benton County
Walla Walla
County
Benton Clean Air Agency

7. Where does Ozone come from?

8. Sources of NOx

9. Sources of Volatile Organic Compounds

12. Summer of 2014 – mobile monitoring

13. August 13, 2015 (77 ppb)

14. Permanent Monitor Installed at BCAA in 2015

16. Timeline Oct. 1, 2015 EPA finalizes 2015 Ozone NAAQS Oct. 1, 2016
October submission requested that Kennewick be declared “unclassifiable” as there are insufficient data to do otherwise
Oct. 1, 2017
EPA finalizes designations based on DVs
Kennewick considered unclassifiable (this is good news)
May 2017 and forward
If monitor readings continue to exceed the standard, there is potential that the area represented by the Kennewick monitor could be declared in non-attainment. (Benton, Franklin, Walla Walla)
2018
Community Outreach to begin to consider ramifications of non attainment and how we might develop solutions
Local Entities explore strategies: Benton Franklin Council of Governments, Benton Clean Air, Department of Ecology, Benton Franklin Transit, Benton Franklin Health Department
Oct. 1, 2020
Ozone standard evaluated for revision
Oct. 1, 2022
(possible) Non-attainment designation

17. Affected Communities
Regulated Sources
Stationary sources of air pollution currently in a permit program:
gas stations
autobodies
food processing
chemical plants
fertilizer plants
Effects of Non-Attainment New Source Review
Transportation Infrastructure
Transportation projects and planning
Transportation Conformity
Economic Development
Impact on manufacturing/production establishment and expansion
Citizens
Health impacts of ozone
Sensitive populations most affected (elderly, young, cardiovascular conditions, allergies)
General Quality of Life
Transportation
Mobile sources –passenger vehicles, trucking, rail shipping, barge/river shipping
Transit
Trip management resources
Many potential impacts; many potential solutions; community effort – thank you for being here this morning.

19. Non Attainment New Source Review
Would apply to new or reconstructed sources of NOx and VOC
Lowest Achievable Emissions Rate (LAER)
The term "lowest achievable emission rate" means for any source, that rate of emissions which reflects:
the most stringent emission limitation which is contained in the implementation plan of any State for such class or category of source, unless the owner or operator of the proposed source demonstrates that such limitations are not achievable, or
the most stringent emission limitation which is achieved in practice by such class or category of source, whichever is more stringent. 
Best Available Control Technology (BACT) is the current standard – it is much more flexible
Result of structured analysis on a case by case basis
Energy consumption, total source emission, regional environmental impact, and economic costs are taken into account.
