The Environmental Protection Agency (EPA) finalized reclassifications for the 2015 ozone National Ambient Air Quality Standard (NAAQS).
The Southern Wasatch Front (Utah County) and Uinta Basin remain at marginal classification with no new regulatory requirements. The Northern Wasatch Front (Salt Lake, Davis, Weber, and Tooele counties) was reclassified to moderate nonattainment. A state implementation plan is due to EPA in January 2023 and must detail how the state plans to attain air quality standards including all emission reduction strategies.
The Division of Air Quality has been planning for this for several years and has identified new rules, which include ultra-low NOx boiler replacements and hot mix asphalt plant controls. These rules will be proposed to the air quality board in the coming months.
