Loophole Lets Air Regulators Wipe Pollution From Records

The Clean Air Act is a more than 50-year-old federal law that allows the EPA to set standards to protect public health by regulating emissions of hazardous air pollutants. But an investigation by the California Newsroom found that a little-known provision forgives pollution caused by “natural” or “uncontrollable” events – like wildfires. And this “exceptional events rule” is being used more and more by local air regulators, alongside extreme weather events associated with climate change. Which means the air on paper might be cleaner than it actually is. And that has significant consequences to public health. Molly Peterson is an investigative reporter at the California Newsroom, a collaboration of public radio stations around the state and CalMatters, and joins Insight with more behind the findings, as well as solutions.

CapRadio Environment Reporter Manola Secaira spoke to researchers at UC Davis about what they have learned from roadkill, why certain areas are more susceptible, as well as what the state of California is doing to better track and conserve native species.
