  1. Overview of Increment Trackingand Cumulative EffectsModeling Issues WESTAR Fall Technical Conference Seattle 15-17 September 2003 Philip Allen, Oregon DEQ

  2. What is included in Increment Tracking & Cumulative Effects analysis? • PSD Class I Increment • Air Quality Related Values (AQRVs) • Deposition • S • N • Visibility • Ammonium Sulfate [(NH4)2SO4] • Ammonium Nitrate [NH4NO3] • Particulate Matter (PM) • Ozone [O3]

  3. What are the resources to work with? • Meteorology • Observations (surface-upper air) • MM4/MM5 (80, 36, 12, 4 km) • Emissions Inventories • State • Regional • Data Management (met, EI, model results) • State • Regional • The International Connection • shared domains, met, models, EI • Models • CALPUFF • CMAQ • AERMOD

  4. WESTAR Area of Interest

  5. Regional airsheds andoverlapping jurisdictions? • Pacific NW • Pacific SW • Colorado Plateau • Rocky Mt West • Northern Plains • Colorado-New Mexico • FLM jurisdictions

  6. U.S.D.A. Forest Service Regions Region 6 Region 1 Region 4

  7. A brief example of a Class I Cumulative Effects Analysis in the Pacific NW • Bonneville Power Administration (BPA) • NEPA study on proposed power plants • conducted in 2001 • Proposed plants only • No existing industrial point sources • No area and mobile sources

  8. Federal Class I Areas: Oregon and Washington

  9. Regional wind fields based on MM5 at 12 km

  10. BPA Study: Class I areas and example baseline sources

  11. BPA Study: Max 24-hr visibility extinction (1Mm) from baseline sources

  12. Pacific NW and the Columbia Basin

  13. Examples of regional studies • Chuck Machovec: SW Colorado-Northern New Mexico • Ken Rairigh: Wyoming
