EPA Cracks Down on California's Slow Air Quality Progress in Valley
Published Date: 4/2/2026
Proposed Rule
Summary
The EPA found that California’s San Joaquin Valley didn’t meet the 2006 air quality standards for tiny pollution particles (PM2.5) by the 2019 deadline. They’re now denying California’s request for more time and asking the state to speed up pollution cuts to clean the air faster. This means California must update its plan to reduce pollution by 5% each year and get serious about cleaner air soon.
