Air pollution limits in Utah's most polluted counties would be set under this bill, which creates a statewide cap on how much fine particle pollution and nitrogen oxide pollution large industrial facilities and other stationary sources can collectively release each year. The cap would apply to "major nonattainment counties" — defined as first- or second-class counties that fail to meet federal air quality standards for ozone, PM2.5, or nitrogen oxides, and specifically naming Davis, Salt Lake, Utah, and Weber counties. Combined annual emissions from these point sources in those counties could not exceed 1,418 tons of PM2.5 (tiny airborne particles linked to lung and heart disease) or 8,870 tons of nitrogen oxides. The bill would take effect May 6, 2026.
