Phoenix residents are bracing for a change in air quality rules as the Environmental Protection Agency (EPA) tightens standards on fine particulate matter, impacting communities across Maricopa County. The crackdown, instigated by the EPA this week, indicates that the acceptable levels of fine particulate matter, also known as PM2.5, will now be lowered from 12 micrograms per cubic meter to 9, in a move to protect public health from the dangers of air pollution. According to a report by ABC15, this could trigger stricter no-burn rules in the area, particularly if the county fails to meet these updated standards by year-end.
Hazel Chandler, who has suffered from asthma throughout her life, recounted a severe health scare she believes was caused by air pollution to ABC15, saying, "I coughed so hard, and nothing would touch it." Ari Halpert, a spokesperson for the Maricopa County Air Quality department, warned that residential wood burning is the leading cause of PM2.5 pollution in the county. He explained the phenomenon of pollution being trapped over the Valley, "There is a type of lid that is created over the Valley. This traps air pollutants and they may remain there for days, or even weeks, even after all the woodburning and the fireworks."
Analysis from the EPA also reveals that Maricopa County currently meets the old pollution standard but falls short of the new one. This could prompt local officials to devise a targeted action plan for high-pollution areas to meet the standard by 2032, an initiative that would involve increased regulations for woodburning on no-burn days.
In terms of healthcare impact, Hilda Berganza of the Hispanic Access Foundation highlighted the disproportionate effect that soot pollution has on Latino communities. Berganza told ABC15, "The Latino population primarily works and lives and plays by many of the sources that produce these pollutants, the soot pollution." Furthermore, the EPA believes that enforcing the stronger standard could save around 4,500 lives over the next eight years nationwide. In a separate move, the agency has proposed to disapprove the current Maricopa County air quality plan for not effectively controlling emissions of coarse particulate matter, or PM-10, based on findings documented by the EPA in earlier reports.
With pressure mounting on Arizona to comply with federal standards, EPA has identified deficiencies in the existing plan from the State, which failed to correctly inventory the sources of PM-10. EPA Regional Administrator for the Pacific Southwest, Jared Blumenfeld, has been clear: "Phoenix has an air quality problem that EPA is committed to solving." He elaborated that although there are steps in the plan that address pollution, "more aggressive measures are needed to achieve air quality standards." The state is now tasked with revising their strategy to avoid potential sanctions, including more stringent facility permitting requirements and possible highway funding restrictions, ensuring residents can breathe a little easier in the near future.
