Flag days: First business joins Arizona program on air-quality alerts

PHOENIX – The nearly 250 employees who work at Coreslab Structures in Phoenix could have looked up one June morning to see a yellow flag flying on top of their building.[caption id="attachment_91988" align="alignright" width="300"] A yellow flag from the ADEQ's Air Quality Flag Program flies above Coreslab Structures’ building in Phoenix, signifying some pollution issues for the day.

More than 200 schools are part of the program, which is open to everyone.“To me, it kind of seemed like a no brainer,” said Brandon Dickerson, plant safety coordinator at Coreslab. “Everything we do here in the production yard is completely outside.”The Arizona Department of Environmental Quality established the Air Quality Flag Program in 2007 to alert the public to high-pollution advisories. Based on the Environmental Protection Agency’s Air Quality Index, there are four colors: red, orange, yellow and green. “Red, for instance, means we are over a federal health-based standard,” said Timothy Franquist, air-quality director at ADEQ. “Green means that we are in good for the air quality for the day.”In 2017, Phoenix had 42 days in which ozone levels exceeded the EPA’s recommended limit, which would signal a red or orange flag, according to the ADEQ.[related-story-left box-title="Related story" link="https://cronkitenews.azpbs.org/2018/04/30/environmental-factors-could-threaten-the-health-of-arizona-residents/" image="https://cronkitenews.azpbs.org/wp-content/uploads/2017/06/Heat-Warning-4-800.jpg" headline="Extreme heat, other environmental factors could threaten health of Arizona residents"]The American Lung Association in April listed the Phoenix area as the eighth most polluted city in the country.Franquist said certain groups – including people with asthma or other respiratory diseases, children and elderly people – are sensitive to higher ozone levels and particulates.Individuals who enjoy activities outdoors also are susceptible to the risks of poor air quality.“We just want to let those community members know what the air quality is like that day so they can take the proper precautions to either limit their exposure or maybe go out at different times of the day,” Franquist said. Most Arizona participants in the flag program are schools because children tend to be the most sensitive population, Franquist said.“The real key to this is this is a voluntary program,” Franquist said. “We have over 200 schools, but it’s open to everybody – businesses, government agencies – the more people that participate, the more we can get the message out to the residents of Arizona.”For more information or to participate, go to the Arizona Department of Environmental Quality’s website.This story is part of Elemental: Covering Sustainability, a new multimedia collaboration between Cronkite News, Arizona PBS, KJZZ, KPCC, Rocky Mountain PBS and PBS SoCal.Subscribe to Cronkite News on YouTube.
