Uintah Basin 2012 Winter Ozone Study Governor’s Energy Summit 2/15/2012 Brock LeBaronRandy Martin
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
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
Ozone Formed in the AtmosphereOzone formation in the troposphere requires both NOxand VOCs NOx + VOC + Sunlight = O3
5-Day Episode – Ouray Site 2011 Non-regulatory Data Peak ozone value twice the federal standard
USU/EDL Special Monitoring Study Winter 2010/2011 • Ozone 1-hour at 3 pm Feb 16, 2011 • Basin-wide O3EDL 2011 O3 study report
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
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.
Uintah Basin 2012 Study Plan UDEQ Oversight • Study Team includes researchers from: • Utah State University/Energy Dynamics Lab • NOAA ‐ Chemical Sciences and Global Monitoring Divisions • University of Colorado • Utah Dept of Environmental Quality • Funding: • Uintah Impact Mitigation Special Service District • Western Energy Alliance • BLM Utah State Office • EPA Region 8 • In‐kind contributions from NOAA and Utah DEQ* Largest air quality study ever conducted in Utah
Study Components• Two Long‐term Trends Sites ‐ USU/EDL/UDEQ • Distributed Monitoring Study ‐ USU/EDL • Chemical Processes Study ‐ NOAA• Mobile Platform Studies ‐ NOAA• Vertical Profile Study ‐ CU• Emissions Inventory and Activity Data ‐ EDL
Study Period• Routine ambient monitoring data to be collected throughout winter 2011‐2012• Special research studies to be focused on February 2012.

Summary • Recognition of an air quality problem • Proactive approach to finding a solution • Cooperative, voluntary effort • Mitigation will be science based • Jurisdictional issues to addressWebsite: www.airquality.utah.gov Click on Uintah Basin Air Quality and Energy Development
