On October 1, 2015, the U.S. Environmental Protection Agency (EPA) promulgated revised primary and secondary ozone National Ambient Air Quality Standards (NAAQS) strengthening both standards to a level of 0.070 parts per million (ppm).
On June 4, 2018, EPA issued designations for the three (3) nonattainment areas in Utah:
- Portions of Utah County (Southern Wasatch Front Nonattainment Area)
- Portions of Weber, Davis, Tooele, and Salt Lake counties (Northern Wasatch Front Nonattainment Area).
- Portions of the Uinta Basin at or below 6,250 feet in elevation and within jurisdictions subject to state air-quality regulation (Uinta Basin Nonattainment Area)
Currently, all nonattainment areas in Utah are classified as Marginal, meaning UDAQ has not had to develop a state implementation plan (SIP) for ozone to date. Further information about UDAQ’s current status can be found on their website.
Areas classified as marginal nonattainment have three years to attain the standard. For these Utah areas that means the attainment date is August 1, 2021 so, UDAQ will be contacting major sources in coming weeks and preparing stakeholders outreach about anticipated changes to attainment status designation and future requirements to progress toward ozone attainment.
What this means to you
For three Utah ozone non-attainment areas, the EPA’s 0.070 ppm attainment date is August 1, 2021. Utah’s Department of Air Quality will be contacting major sources in coming weeks in these areas and preparing stakeholders outreach about anticipated changes to attainment status designation and future requirements to progress toward ozone attainment.
