EPA Proposes to Classify Utah’s Northern Wasatch Front as Meeting Ozone Standards

The Environmental Protection Agency is proposing to determine that the Northern Wasatch Front air quality area in Utah, which includes the Salt Lake City metropolitan region, has met the 2015 federal ozone standard by its required deadline. The agency’s proposal relies on air quality monitoring data that shows the area is compliant, but only after excluding certain days where international pollution contributed to the readings.

Why it matters: If finalized, this action would spare Utah from the stricter regulatory and reporting requirements that come with a Serious nonattainment designation. The state would not be forced to adopt additional vehicle inspection programs, industrial controls, or contingency plans specifically tied to the 2015 ozone standard. The practical effect is mostly administrative: it updates the federal air quality classification for the region and closes out a compliance track that would otherwise require ongoing state planning and potential penalties.

Who it affects

• Utah state and local air quality agencies, particularly the Utah Department of Environmental Quality
