EPA Finding That Sacramento Area Is Meeting Federal Air Quality Standards
Official: Clean Data Determination; 1997 8-Hour Ozone Standards; California; Sacramento Metro Area
Reading: The clean data determination suspends (rather than eliminates or tightens) existing Clean Air Act requirements, reflecting attainment of an established 1997 ozone standard without changing the underlying protection level.
This is based on air quality measurements from 2023–2025.
In clear language
The EPA is proposing to declare that the Sacramento Metro area in California has achieved and is maintaining the federal air quality standard for ozone pollution (a key smog component). If approved, this declaration will suspend certain Clean Air Act requirements for the area as long as it continues to meet the standard. This is based on air quality measurements from 2023–2025.

The EPA is approving New York's air quality plan to ensure that sulfur dioxide pollution from New York doesn't harm air quality in neighboring states like New Jersey. Under federal law, each state must show it's controlling pollution so it doesn't drift across borders and worsen air quality elsewhere. This approval confirms New York is meeting that requirement for a specific air quality standard.
