How California’s air quality could be impacted
The Federal EPA is proposing to strengthen the primary health-based air quality standard for fine particulate matter, known as PM2.5 or soot.

For California, the Air Resources Board (CARB) estimates that lowering the current annual PM2.5 standard in the range of 8-10 micrograms could prevent 4,600 annual premature deaths, 850 heart and lung disease hospitalizations, and 2,100 asthma emergency room visits.

CARB research has shown that PM2.5 air pollution exposure is linked to a growing number of additional health problems.

CARB’s Executive Officer Dr. Steven Cliff applauded EPA’s move toward stronger standards. “In light of the fact that over half of mobile source emissions in California come primarily from federally regulated sources, such as locomotives, ships and airplanes, it is imperative that EPA expeditiously approve California’s waiver requests”, he said.
