  1. Air Quality Trends in the Lower Fraser Valley of BC Metro Vancouver Georgia Basin Puget Sound International Airshed Strategy Meeting September 24, 2009

  2. Regional Emission Inventory and Forecasts Ambient Air Quality Monitoring Air Quality Management Plan Development and Implementation Regulatory Program Education and Outreach Coordination with Other Governments Integrated Air Quality Management Program

  3. Evolution of the Air Monitoring Function • Air quality monitoring was one of the first functions of the AQ program – established in 1972 • In 2007 commissioned a consultants’ review • Technological improvements to both instruments and data acquisition systems • Increased focus on human health • Regional growth, sprawl (e.g. FVRD) • changes in sources and locations • Rationalize existing network of fixed stations • Enhance portable / mobile capabilities • Super sites • Improve information to public • www.bcairquality.ca • Advisories, AQHI “update and improve the ambient monitoring network to respond to ongoing changes in regional and local air quality management priorities and needs.” - AQMP, 2005

  5. Ambient Air Quality Objectives for Greater Vancouver

  6. PM2.5 (2008)

  7. Ozone (2008)

  8. PM2.5 Trends

  9. NOx and SOx Trends

  10. Regional Ozone Trends

  11. Emissions of some contaminants have decreased or levelled off While others are forecast to increase Emission Inventory

  12. Key Challenges • Improve understanding of ozone formation • Visibility management • Climate change • Enhance / improve data and assessment • Inventories and monitoring • Air quality and health interface • Diesel, wood smoke, toxics, land use and transportation • Communities • Improve ability to respond to localized hot spots (nuisance and health issues)
