Utah Basin Gets Extra Year to Clear Ozone Air Quality Hurdles
Published Date: 4/23/2026
Proposed Rule
Summary
The EPA is proposing to give Utah’s Uinta Basin a second one-year extension to meet clean air rules for ozone pollution, moving the deadline from August 2022 to August 2023. This means the area won’t be bumped up to a stricter pollution category and can keep its current status. This change affects local communities and the Ute Indian Tribe, helping avoid tougher regulations and extra costs for now.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
One-Year Attainment Date Extension
The EPA proposes to extend the Uinta Basin attainment date from August 3, 2022 to August 3, 2023 and to determine the area attained the 2015 ozone standard based on certified 2020–2022 monitoring data. If finalized, the area would remain a Marginal nonattainment area and would not be reclassified to Moderate, avoiding the stricter requirements tied to reclassification for now. This proposal explicitly affects local communities and the Ute Indian Tribe in the Uinta Basin and is intended to avoid additional regulatory burdens and extra costs during the extension period.
No Significant Small-Entity Impact
The EPA certifies that this proposed action will not have a significant economic impact on a substantial number of small entities and will not impose any new requirements on small entities. That certification means the rule, as proposed, will not directly create new compliance obligations for small businesses.
