  1. 2010 OZONE SEASON SUMMARYMarch 2, 2011 MEDEP Monitoring Meeting Tom Downs, CCM Chief Meteorologist Maine DEP-BAQ 17 State House Station Augusta, ME 04333-0017 TEL: 207-287-7026 E-MAIL: tom.downs@maine.gov

  2. 1997 8-hour NAAQS 84 ppb Primary = secondary Entire state is designated ATTAINMENT with SIP maintenance plans in place Current SIP designations are only for the 1997 NAAQS 2008 8-hour NAAQS 75 ppb Primary = secondary EPA does not plan to designate due to the ozone NAAQS reconsideration. 2011 8-hour NAAQS ????July 31, 2011??? OZONE STANDARDS

  3. Exceedance day Analysis Tools • HYSPLIT Trajectory analysis (using AIRNOW TECH) • 24-hr back trajectory starting at 10, 250, 500 and 1000m levels • Only for monitors with 8-hr concentrations > 70 ppb • AIRNOW TECH Observations (only preliminary data available) • NOAA-EPA CMAQ model (previous day forecast) • Barons 45-km MAQSIP model (previous day forecast)

  4. May 1, 2010: Highest 1-hr concentration at Cadillac Mt was 56 ppb (Trajectories only for hours > 70 ppb [5/2 0300-0600 EST] ) OBSERVED AQI (75 ppb NAAQS) BARONS MAQSIP forecast 5/1 2300 EST 8-hr Ozone concentrations 24-hr back trajectories - 250m (black lines) 500m (gray lines) 1000m (light gray lines 12Z and 00Z 850mb and surface maps NOAA-EPA CMAQ forecast

  5. May 2, 2010: (Trajectories only for hours > 70 ppb [1300-1700 EST] ) OBSERVED AQI (75 ppb NAAQS) BARONS MAQSIP forecast 1100 EST 8-hr Ozone concentrations 24-hr back trajectories - 10m (black lines –SHAP) 250m (black lines-CAD gray lines-SHAP) 500m (gray lines-CAD) 12Z and 00Z 850mb and surface maps NOAA-EPA CMAQ forecast

  6. July 5, 2010: (Trajectories only for hours > 70 ppb [1600-1800 EST] ) OBSERVED AQI (75 ppb NAAQS) BARONS MAQSIP forecast 1300 EST 8-hr Ozone concentrations 24-hr back trajectories - 10m (black lines) 250m (gray lines) 12Z and 00Z 850mb and surface maps NOAA-EPA CMAQ forecast

  7. July 8, 2010: (Trajectories only for hours > 70 ppb [1100-1700 EST] ) OBSERVED AQI (75 ppb NAAQS) BARONS MAQSIP forecast 1000 EST 8-hr Ozone concentrations 24-hr back trajectories - 10m (black lines) 250m (gray lines) 1000m (light gray lines) 12Z and 00Z 850mb and surface maps NOAA-EPA CMAQ forecast

  8. July 17, 2010: (Trajectories only for hours > 70 ppb [1300-1700 EST] ) OBSERVED AQI (75 ppb NAAQS) BARONS MAQSIP forecast 1200 EST 8-hr Ozone concentrations 24-hr back trajectories - 10m (black lines) 250m (gray lines) 12Z and 00Z 850mb and surface maps NOAA-EPA CMAQ forecast

  9. July 28, 2010: (Trajectories only for hours > 70 ppb [SW & Mid-Coast-1400EST][Shapleigh & West Buxton-2000 EST] ) OBSERVED AQI (75 ppb NAAQS) BARONS MAQSIP forecast 1300 EST 8-hr Ozone concentrations 24-hr back trajectories - 10m (black lines) 250m (gray lines) 12Z and 00Z 850mb and surface maps NOAA-EPA CMAQ forecast

  10. September 1, 2010: (Trajectories only for hours > 70 ppb [SW-Coast-1600EST][Port Clyde-2000EST][Acadia NP 2300EST] ) OBSERVED AQI (75 ppb NAAQS) BARONS MAQSIP forecast 1500 EST 8-hr Ozone concentrations 24-hr back trajectories - 10m (black lines) 250m (gray lines-(ANP black lines)) 500m (gray lines-ANP) 12Z and 00Z 850mb and surface maps NOAA-EPA CMAQ forecast

  11. September 2, 2010: (Trajectories only for hours > 70 ppb [SWCoast-1700EST][Bowdoinham & Port Clyde-1900EST][Acadia NP & Jonesport 2100EST] ) – Hurricane moving up the coast OBSERVED AQI (75 ppb NAAQS) BARONS MAQSIP forecast 1400 EST 8-hr Ozone concentrations 24-hr back trajectories - 10m (black lines) 250m (gray lines-(ANP black lines)) 500m (gray lines-ANP) 12Z and 00Z 850mb and surface maps NOAA-EPA CMAQ forecast

  12. September 3, 2010: (Trajectories only for hours > 70 ppb [1000-1300 EST] ) OBSERVED AQI (75 ppb NAAQS) BARONS MAQSIP forecast 0700 EST 8-hr Ozone concentrations 24-hr back trajectories - 250m (black lines) 500m (gray lines) 12Z and 00Z 850mb and surface maps NOAA-EPA CMAQ forecast

  13. Ozone Season Trends No change early in the Season -Pinenes? -Climate change? Significant decrease during the peak ozone season months -NOx SIP call controls -Other local and regional NOx and VOC controls

  14. Summary • Meteorological Conditions were more conducive to ozone formation during the 2010 ozone season than the previous two seasons • All monitoring sites in Maine are attaining the current 75 ppb 8-hour Ozone NAAQS

  15. February 17, 2011 2:00 PM Ozone concentrations

  16. N/A-MAINTENANCE AREA SITES • Cadillac Mt. Summit (PAMS) • Kennebunkport • Cape Elizabeth (PAMS) • McFarland Hill • Durham • Gardiner • Port Clyde • West Buxton • Shapleigh • Bowdoinham • OZONE MAPPING & RURAL SITES • Jonesport • Holden • North Lovell • EPA CASTNET SITES • Howland • Ashland • TRIBAL SITES • Indian Island (Penobscot Nation) • Presque Isle (MicMac) • Sipayik (Passamaquoddy) • HEALTH STUDY SITE • Portland 2011 High elevation site for transport study and Secondary NAAQS? Best Downwind of Portland coastal site?
