EPA Moves to Reclassify Ozone-Polluted Areas
Published Date: 6/12/2026
Proposed Rule
Summary
Some states are being reclassified because their air has more ozone pollution than allowed. This means they need to update their plans to clean the air faster and follow new rules. These changes affect local governments and businesses, with deadlines to meet and possible costs to help make the air healthier.
Analyzed Economic Effects
2 provisions identified: 0 benefits, 1 costs, 1 mixed.
State Ozone Reclassification Requires SIP Updates
If you live in a state that is reclassified for ozone, your state must update its State Implementation Plan to clean the air faster and follow new rules. The reclassification means state and local authorities must change how they control ozone pollution to make the air healthier.
Local Governments and Businesses Face Deadlines, Costs
Local governments and businesses in reclassified areas will have deadlines to meet new requirements and may incur costs to comply with rules aimed at reducing ozone pollution. These costs and deadlines come from the need to update plans and implement faster emission controls.
