The Environmental Protection Agency is proposing to approve changes to how California calculates its motor vehicle emissions in the San Joaquin Valley. These changes specifically target nitrogen oxides and volatile organic compounds, which are chemicals that contribute to ground-level ozone (smog).
Why it matters: This is largely an administrative update to ensure the state’s air quality tracking uses its most recent and approved mathematical models.
Who it affects
- California state environmental regulators
This is a proposed rule from the EPA; readers should consult the Federal Register to see the full technical details before relying on these figures.
