The Valley Air District says local air quality forecasts might soon get worse, even if the air  is actually getting better. FM89’s Joe Moore explains. 

The problem is summertime ozone pollution. Last year, the valley exceeded the federal, 8-hour ozone health standard 80 times. That sounds like a lot, and it is, but it’s also the lowest level on record for the region, and it’s down over 25 percent since 2011.

Former Senator Dean Florez says the San Joaquin Valley Air Pollution Control District isn't doing enough to protect the health of local residents. Last week Florez was appointed to the powerful California Air Resources Board (CARB) by California Senate leader Kevin de Leon.  

Florez: "I think there's a lot more they could be doing. I think they should move quicker. There's a lot more tools in their toolbox than there were 10 years ago. Anything I can do to make this board move quicker from the state level, I'm going to do."

New research this week questions the connection between air pollution and asthma.

In 2011, a study by the San Joaquin Valley Air Pollution Control District established a link between asthma-related ER visits and levels of PM2.5, or fine particulate matter in valley air.  But after a follow-up to that study, the Air District now reports that for a number of years, asthma-related ER visits increased even as PM2.5 levels dropped.

David Lighthall, health science advisor to the Air District, says the findings should not be interpreted as black and white.

Here in the Central Valley – in one of the most polluted air basins in the country – we know that poor air is bad for our health. We feel it in our eyes and throat, and when we struggle to breathe.

But what if air pollution is affecting us at a deeper, cellular level?

That's exactly what Dr. Kari Nadeau discovered a few years ago. She’s a Stanford School of Medicine professor with an expertise in asthma and allergies.

In the decades-long effort to clean up the San Joaquin Valley's notoriously poor air, 2013 might be a milestone. For the first time, the air basin had zero violations of the hourly federal ozone standard.  

That news prompted the governing board of the San Joaquin Valley Air Pollution Control District to vote Thursday to formally request that the EPA lift a required a $29 million annual penalty.
