Clean air standards are being reduced, despite clear evidence of the health impacts

In line with an array of rollbacks on environmental and public health guidelines from the federal government, the EPA has decided not to defend their last recommendation for the PM2.5 standard. The new rule would have reduced the allowable level from 12 to 9 micrograms per cubic meter, which could have made a significant impact for states struggling with air quality. 

Even though Utahns could have significantly benefited from decreased PM2.5, Utah was one of the states that filed a lawsuit to stop the implementation of cleaner air standards. 

PM2.5 is some of the most damaging to human health, because it is among the smallest particle sizes, so it is easily inhaled, and can easily enter the bloodstream and brain. A recent Salt Lake Tribune article reported on recent studies connecting PM2.5 levels to Alzheimer’s, dementia, and Parkinson’s, expanding on a growing body of research showing the hazards. These studies are what UPHE bases our work and our stances off of. 

The EPA found that meeting the stronger standard would provide benefits for public health valued at $46 billion each year once all areas come into compliance, while costing less than 1.5% of that amount.

In 2020, a University of Utah study found that air pollution costs Utahns billions annually and shortens life expectancy by two years.

Clean air standards should reflect the best available science and prioritize human health. As new research continues to show just how far-reaching the impacts of air pollution are, rolling back protections leaves communities more vulnerable, especially here in Utah, where geography and policy already stack the deck against clean air. UPHE remains committed to pushing for evidence based standards that safeguard the health of Utah residents.
