A concerning shift in how the EPA calculates air pollution's impact could potentially put Americans' health at risk. This new rule, according to environmental groups and health experts, changes how the Environmental Protection Agency assesses the benefits of reducing air pollution. But what does this mean for you? Let's dive in.
Previously, the EPA used a dollar value to quantify the health benefits of cleaner air, taking into account factors like fewer premature deaths and illnesses, such as asthma attacks. However, the agency will no longer apply a dollar value to the health benefits resulting from regulations on fine particulate matter (PM2.5) and ozone. The EPA states this is due to uncertainties in the estimates, as outlined in their recent regulatory impact analysis.
While the EPA won't monetize these benefits, they will continue to quantify emissions. They plan to reinstate the monetization once they are confident in their modeling. The EPA Administrator, Lee Zeldin, has stated that lives saved will still be considered when setting pollution limits. An EPA spokesperson reiterated that the agency still considers the impact of emissions on human health, but will not be monetizing these impacts at this time. They emphasized that not monetizing does not mean they are not considering or valuing the human health impact, and that the EPA is committed to protecting human health and the environment.
But here's where it gets controversial... Fine particulate matter and ozone (soot and smog) are two of the most dangerous and widespread pollutants in the U.S. These pollutants come from various sources, including vehicles, power plants, agriculture, and oil refineries. One expert suggests that the rule change could lead to increased emissions, potentially favoring more pollution. Another expert claims that the EPA is removing a tool that has been useful for evaluating the impact of existing and new regulations.
Interestingly, the Biden administration also did not monetize many air pollutants in its rules. Under the Clean Air Act, the EPA must review and revise nitrogen oxide (NOx) standards every eight years. However, the EPA failed to update the NOx standards for new gas plants for 18 years. The Biden administration proposed revisions in November 2024 in response to a 2022 lawsuit.
And this is the part most people miss... The implementation of this rule change is a departure from the norm. Typically, public comment would be part of the process. In the 1980s, industry executives pushed for benefit-cost analysis. Attributing health benefits to a dollar amount is part of the โrigorousโ economic analysis the EPA has used for decades. One expert points out that instead of working to reduce the uncertainties, the EPA is using them as a reason to eliminate the approach altogether.
There is strong evidence connecting health outcomes to air pollution. Medical studies have linked PM2.5 exposure to low birth weight and an increased risk of depression. The new rule is seen by some as a reckless refusal to value the health of millions of Americans, despite the evidence linking pollution to asthma, heart disease, and other serious health problems. Low-income and minority communities are likely to face higher exposure to air pollution and develop higher rates of health problems.
Pollution levels have decreased substantially in recent decades due to stricter emissions control. This has led to fewer heart attacks, lung cancer cases, and lung diseases. Improving air pollution makes us healthier and saves lives, and it is one of the most cost-effective ways of improving health and saving lives for all Americans.
