1 PDX Air Quality Overview David Breen Air Quality Program Manager January 16, 2013

2 PDX Air Quality Overview What is the status of the airshed? How do we contribute to it? Are we constrained by it? What are some of the issues coming up? What are we doing about our footprint?

3 Air Quality Context Air quality is both regulated and non-regulated Portland-Vancouver air quality is good and improving PDX s contribution to airshed is relatively small Less than 4% PDX actively working to track and improve performance at PDX and with partners

4 Types of Air Pollutants Criteria Air Pollutants Hazardous Air Pollutants (189) or "Air Greenhouse Gases Toxics" - Particulate Matter 10 (diesel engines) - Carbon Dioxide - Particulate Matter Diesel Particulate Matter - Methane - Nitrogen Dioxide - Benzo(a)pyrene - Nitrous Oxide - Sulfur Dioxide - 1,3 Butadiene - Lead - acrolein - Ozone - Carbon Monoxide (gasoline engines) - Benzene (Jet Aircraft) - Formaldehyde (Piston Aircraft) - Lead

5 Criteria Pollutants Federal Air Quality Standards Air Toxics Federal Engine Emission Standards, etc. Oregon Ambient Benchmark Concentrations (52) 5

6 Greenhouse Gasses Regulatory: Federal Permit Limits Stationary Sources Vehicle Emission Standards State GHG Reduction Goals Initiatives: City of Portland and Multnomah County Climate Action Plan (2009) Oregon Global Warming Commission Roadmap to 2020 (2011)

7 Status of the Airshed Criteria Pollutants

8 Criteria Pollutants - How is Air Quality Determined? Monitoring

13 Criteria Pollutants Port Contribution

14 NOx Emissions PDX Emissions Trends Criteria Pollutants (Tons) CO and HC Emissions

15 NOx Emissions PDX Emissions Trends Criteria Pollutants (Tons per Passenger) CO and HC Emissions CO NOx HC 0

16 Capacity to Grow Aviation (Air Permit)

17 DEQ Portland Air Toxics Solutions (PATS) Established aspirational goals for 52 air toxics Modeled 19 air toxics for Model showed 15 above benchmarks Identified 5 top priority sources for focus Residential wood combustion Light duty vehicles (mostly gasoline powered) Heavy duty vehicles (mostly diesel powered) Construction equipment (mostly diesel powered) Industrial metals facilities

18 Air Toxics Formaldehyde 4.78% 19.12% 76.10% Passenger Vehicles Aircraft Aircraft Service Equipment

19 Air Toxics Lead Modeled to be below benchmarks around all the airports FAA Fuels Program Office replacement fuel by 2018

20 Air Toxics Diesel Particulate Matter 3.44% 26.88% 69.68% Port Fleet Aircraft Service Equipment Cargo vechicles

21 Air Toxics Port Controlled Emissions

22 Greenhouse Gases Portland International Airport 2006 Emissions by Ownership & Control Public 190,696 9% PDX 55,541 3% Airline/Tenant 1,867,254 88%

23 What are we doing about our emissions footprint?

24 PDX Future Emission Reduction Opportunities Identify ways to influence the use of cleaner construction equipment on Port construction projects Encourage and support the use of greener ground service equipment Encourage and support the use of aircraft preconditioned air at more gates Continue partnership on aircraft technology

25 PDX CAC Discussion Questions Questions for clarification? What additional recommendations would you offer the Port on air quality? Sustainability Goals: Adaptive Management Leadership Accountability Carbon neutrality by 2035 Eliminate toxic substances Diversify transportation options Renewable power and energy efficiency
