The Moderate Ozone SIP Development is very much an iterative process. The technical foundation of any SIP involves numerous emissions inventories, air quality modeling assumptions, potential emission controls, and ever-fluctuating design values recorded throughout the air monitoring network. The Ozone Implementation Rule is very prescriptive about how these numbers must fit together to comprise an …
Read MoreOzone Overview What is Ozone? Ozone in the Uinta Basin Current Air Quality Ozone is a colorless gas comprised of three oxygen atoms. It is not emitted directly into the air as a gas but is formed through a chemical reaction between nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the presence of sunlight. …
Read MoreOverview Read about the Utah SIP Overview Within two years after setting or revising NAAQS for criteria pollutants, the EPA must designate areas as meeting (attainment) or not meeting (nonattainment) the air-quality standard. The EPA’s final designations are based on the most recent three years of air-quality monitoring data, recommendations from the state, and additional …
Read MoreRACT Overview Under the Clean Air Act, all areas designated Moderate nonattainment for the 2015 8-hour ozone standard are required to implement RACT for all existing major sources of VOCs or NOx (100 tons per year of either pollutant) as well as all VOC sources subject to an EPA Control Technique Guideline (CTG). A RACT …
Read MoreRACM Overview Under the Clean Air Act, all areas designated Moderate nonattainment for the 2015 8-hour ozone standard are required to implement RACM for point, area, off-road, and on-road source categories. RACM applies only to those point sources not already addressed as part of a RACT analysis. RACM implementation is required to be as expeditiously …

Ozone is formed in Utah when NOx and VOCs break apart under intense sunlight and reform. The formation of ozone is most likely to occur on days with calm winds, no cloud cover and afternoon temperatures above 90 degrees. Here are some ways you can protect your health and reduce your emissions.

Read MoreHigh wintertime ozone concentrations are relatively new phenomena in rural areas of the West. First observed in 2005 in the oil and gas production areas in the Upper Green River Basin (UGRB) of Wyoming, preliminary studies showed that wintertime ozone levels would spike when snow cover, sunny skies, and strong temperature inversions trapped ozone and …
Read MoreStarting in the winter of 2012, the Uinta Basin Ozone Study (UBOS) (2 MB) launched a wide-ranging research effort into the ways atmospheric chemistry and precursor gases interact to create high levels of wintertime ozone. The study was by far the largest and most complex air quality study ever conducted in Utah. This effort was …
Read MoreTeams of scientists continued their work in the Uinta Basin in 2013 to identify the sources and conditions that create ozone during winter inversions. The Division of Air Quality (DAQ) and its partners collected additional data to improve their understanding of the atmospheric chemistry that leads to the formation of wintertime ozone in the Basin. …
