Officials with the Valley Air District are warning about Fourth of July fireworks worsening air quality and threatening residents' health.

Fireworks can cause damaging air pollution to spike to five times the level considered safe.

When fireworks are set off, they burn, explode and release large amounts of dangerous particulate matter into the atmosphere.

Heather Heinks with the San Joaquin Valley Air Pollution Control District says the tiny particles of soot, ash and metal can bury themselves deep in the body causing short and long term problems.

A massive fire at a lumberyard in Fresno has prompted officials with the Valley Air District to issue a health caution for residents from Fresno to Kern Counties.

The two to three acre fire began overnight at the McFarland Cascade utility pole yard near Golden State Boulevard. The facility provides wood utility poles to companies throughout the region, including PG&E.

As of Thursday afternoon the fire continued to burn. Pete Martinez with the Fresno Fire Department  says the firefighting efforts were hampered by the lack of a working set of fire hydrants at the site.


  California’s prolonged drought is causing a sharp rise in air pollution in the Central Valley. That’s according to an annual report on air quality in California.

While smog and Ozone continue to improve in the Valley, the four year long drought is pushing up dangerous particulate matter pollution rates.

The dry weather is causing loose soil which is kicked into the air says Heather Heinks with the Valley Air District.

Last week the US Environmental Protection Agency unveiled a plan that would set a new more stringent rule for the amount of ozone pollution in the air. The proposal is based on new research on the health effects of ozone pollution.   

In fact, the EPA says if adopted, the new rule could prevent as many as 4,300 premature deaths nationwide in the next decade. But it has been met with controversy. Republicans and business groups say the positive health benefits are outweighed by the cost of complying with the new rule, some have gone as far as to call it “nearly impossible.”

A California Assemblyman has introduced a bill that would delay part of the state’s greenhouse gas reduction program for at least three years. Under the bill, energy companies would be able to put off purchasing “transportation fuel pollution” permits. Capital Public Radio’s Max Pringle reports.

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.

After 6 years, the state of California has approved the expansion of a toxic waste landfill near Kettleman City. The decision will allow the landfill to expand by 50%, or 5 million cubic yards, which owners at Waste Management Incorporated estimate will last about 8 years.

A new report on air quality shows that many neighboorhoods in Fresno County and Bakersfield rank among the worst in the nation when it comes to pollution.

The American Lung Association released the findings of its annual “State of the Air” report today ranking the Fresno- Madera area as the nation’s worst based on exposure to chemicals and particulate matter.

Last week, the state of California released a new interactive online map that lets you look at how environmentally burdened your neighborhood is compared to the rest of the state. The tool, called CalEnviroScreen 2.0 combines both data on pollution sources and the demographics of a community, including poverty, unemployment and linguistic isolation to compute a score that reflects a community’s overall environmental burden.
