The air we breathe is a cornerstone of our well-being, and accurate information about its quality is crucial. However, a recently uncovered legal loophole reveals that air quality in more than 70 U.S. counties might not be as clean as we’re led to believe.

According to a joint investigation by the California Newsroom, MuckRock, and the Guardian, the US Environmental Protection Agency (EPA) has been making use of the “exceptional events rule” – a provision in the Clean Air Act. This rule allows the EPA to exclude Pollution caused by “natural” or “uncontrollable” events, such as wildfires, from its clean air records. As a result, over 21 million Americans have been breathing air reported to be cleaner than it is.
While the intention might have been to account for anomalies, this rule is being used more frequently, especially with the rising number of wildfires due to global warming. The repercussions are two-fold. First, it gives the public a skewed picture of air quality. Second, it potentially delays stricter Pollution control measures that might have been triggered if the true Pollution levels were acknowledged.
For instance, the summer of 2023 saw more than 20 states reporting higher-than-normal air-quality readings. A significant contributor to this was the Canadian wildfire smoke blanketing parts of the Midwest and eastern US.
What’s alarming is that since the EPA’s last guideline revision on exceptional events in 2016, local regulators in 21 states filed for pollution forgiveness. The EPA approved these requests in 20 of those states. The data adjustments spanned over 70 counties across these states. Sometimes, these adjustments were pushed for by industry lobbyists, who have vested interests in maintaining the status quo, potentially at the cost of public health.
The present situation underlines a pressing need to reconsider how we approach air quality reporting, especially in the face of increasing environmental challenges. The real-life health impacts of such obscured data cannot be underestimated. As Vijay Limaye, a health expert at the Natural Resources Defense Council, noted, the reality on the ground suggests that the air many Americans breathe is getting increasingly unhealthy.
Accurate air quality reporting isn’t just about numbers or regulatory compliance – it’s about the health and well-being of millions. It’s high time we address this loophole and ensure the air we breathe is genuinely clean.
