PDX Air Quality Overview David Breen – Air Quality Program Manager

January 16, 2013

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?

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

Types of Air Pollutants

1 2 3 Criteria Air Pollutants Hazardous Air Pollutants (189) or "Air

Capacity to Grow Aviation (Air Permit)

DEQ Portland Air Toxics Solutions (PATS)

• Established aspirational goals for 52 air toxics

• Modeled 19 air toxics for 2017.

• 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

2006 Emissions by Ownership & Control

What are we doing about our emissions footprint?

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

PDX CAC Discussion Questions

• Questions for clarification?

• What additional recommendations would you offer the

Port on air quality? – Sustainability

• Adaptive Management

• Leadership

• Accountability

– Goals:

• Carbon neutrality by 2035

• Eliminate toxic substances

• Diversify transportation options

• Renewable power and energy efficiency
