Utah's Ozone Zone Grows: EPA Expands Clean Air Mandates Northward
Published Date: 9/25/2025
Proposed Rule
Summary
The EPA is set to approve Utah’s request to expand the Northern Wasatch Front ozone pollution zone, meaning more areas will follow clean air rules to fight smog. This change affects local communities and businesses, who’ll need to meet air quality standards starting when the new boundary goes into effect. It’s a big step to keep Utah’s air cleaner and healthier for everyone.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
More Utah areas face ozone rules
If you live in the newly expanded area of Utah’s Northern Wasatch Front, your community will be designated part of the 2015 8-hour ozone nonattainment area. That means the same Clean Air Act clean-air rules that apply to the original NWF area will apply to your area starting on the effective date of the final EPA action; the State of Utah submitted this expansion request on February 27, 2023.
New compliance obligations for Utah businesses
If you run a business located in the newly expanded portion of Utah’s Northern Wasatch Front, your area will be classified under the 2015 8-hour ozone nonattainment area and all applicable Clean Air Act requirements will apply to that area upon the effective date of the final EPA action. The State of Utah submitted the boundary expansion request on February 27, 2023.
