OEC Webinar: Air Quality & Your Health (part 1) - Erica Fetty & Sarah VanderWielen

  1. 1. Where Does It ComeFrom and How Is ItTracked?Presented byErica Fetty andSarah VanderWielen
  2. 2. Where Does Ozone ComeFrom?• Ozone is not directly emitted into theatmosphere• Ozone is composed of Nitrogen Oxides andVolatile Organic Compounds in the presents ofsunlight• Because ozone forms in the air, it often shows updownwind from the sources
  3. 3. Sources of NOx• Each year the US emits approximately 19.4million metric tons of nitrogen oxides• Cars, Trucks, and Boats• Fuel Combustion• Power Generation (fossil fuel)• Lightning• Forest Fires
  4. 4. Sources of NOx
  5. 5. VOCsTypes• Formaldehyde• Benzene• Toluene• Xylene• AcetoneSources• Paint• Air Fresheners• Tobacco• Dry Cleaning Chemicals• Glues• Household cleaners• Gasoline
  6. 6. Future of Ozone• EPA expects NO2 concentrations will continue todecrease in the future as a result of a number ofmobile source regulations that are taking effect.• Tier 2 standards for light-duty vehicles began phasing in during2004, and new NOx standards for heavy-duty engines are phasingin between 2007 and 2010 model years.• Cleveland, Columbus and Cincinnati metropolitan areas arecurrently non-attainment for 2008 Ozone Standard of 75 ppb.
  7. 7. Where Does PM Come From?PM 2.5 comes from a wide variety of combustionactivities• Fires• Power Generation• Cars, Trucks, Buses• Off-Road Vehicles
  8. 8. How PM 2.5 Forms• Emitted directly from sources like fires• Indirect chemical reactions happen in theatmosphere when sulfur dioxides and nitrogenoxides are emitted• Chemical reactions account for the most fine particle pollution• Power plants, tailpipes
  9. 9. Future of PM 2.5• 1997 Annual Standard of 15.0 µg/m3• Waiting on areas to be redesignated attainment• 2006 24-Hour Standard of 35 µg/m3• Waiting on areas to be redesignated attainment• 2013 Annual Standard of 12.0 µg/m3• December 2013: State designation due• August 2014: U.S. EPA publish purposed designationsfor public comment• December 2014: Final designation
  10. 10. Emissions Inventories• Facilities that have the potential to emit certainamounts of air pollution are required to apply for andobtain a state-federal operating permit and payemission fees• Permit establishes permitted allowable emission rates• Major facilities must submit actual emission reports every year• Synthetic Minor facilities report every year• True Minor facilities report every two years
  11. 11. Emissions Inventories• Ohio EPA data available for download• Point sources• Coal burning reports•• U.S. EPA emissions inventories•
  12. 12. Ohio EPA Inventories
  13. 13. Inventory Report
  14. 14. Monitoring• Ohio has one of the most extensive monitoringnetworks in the county• Ozone• 49 monitors• Parts per billion• Monitored hourly• Particulate Matter• 38 PM monitors• Micrograms per cubic meter• Air filters collected and reviewed at lab•
