Uintah Basin 2012 Winter Ozone Study

  1. 1. Uintah Basin 2012 Winter Ozone Study Governor’s Energy Summit 2/15/2012 Brock LeBaronRandy Martin
  2. 2. Ozone Health Effects• Airway irritation, coughing, and pain when taking a deep breath• Aggravation of asthma and respiratory illnesses• Permanent lung damage with repeated exposures
  3. 3. Formulation of the Federal Health Standard • 75 parts per billion (but subject to change) • “Smooth’s” the effect of extreme events • Protects "sensitive" populations – Asthmatics – Children – Elderly
  4. 4. Ozone Formed in the AtmosphereOzone formation in the troposphere requires both NOxand VOCs NOx + VOC + Sunlight = O3

  6. 6. 5-Day Episode – Ouray Site 2011 Non-regulatory Data Peak ozone value twice the federal standard
  7. 7. USU/EDL Special Monitoring Study Winter 2010/2011 • Ozone 1-hour at 3 pm Feb 16, 2011 • Basin-wide O3EDL 2011 O3 study report
  8. 8. What is the Cause of High Wintertime O3?• We don’t know yet, but …• Relatively few emission source types• Occurs during stable meteorology (physiography + inversion = capped bowl)• Associated with snow cover (enhanced photolysis rates, snow chemistry?)• WY seeing similar winter O3 values• Cooperative study of O3 formation chemistry this winter
  9. 9. This Winter’s Ozone StudyPurpose: to understand how ozone is formed in the Basin during wintertime inversion conditions. Identify the chemical pathways that are unique to the Basin’s winter situation.
