2016 Ozone Pollution Control 
Union of Concerned Scientists
MARCH 1, 2023
EPA’s own scientists concluded in 2016 that the risk value of ethylene oxide is 60 times more toxic than previously understood. You can compare this to ozone which has a half-life on the order of minutes, and some PFAS chemicals that have a half-life in air on the order of several years.

It marks the seventh round of NOx controls for the EGU sector since 1990. The proposed rule would provide de minimus air quality benefits in downwind areas with extremely high costs – estimated by EPA at $22 billion discounted 2016 dollars for the 2023-2042 period. enjoyed ozone reductions of 3 to 5 ppb or more.

One good example of the nexus between global warming and local pollution is ground-level ozone. To make matters worse, NOx contributes to the formation of ground-level ozone and secondary PM2.5, Therefore, controlling for NOx and SOx helps reduce PM2.5 which is formed in the atmosphere from precursor gases such as NOx.

The Obama Administration set the first vehicle GHG emissions standards in 2010 for vehicles manufactured in model years 2012 through 2016, and set revised standards in 2012 for model years 2017 through 2025. In many of the states challenging EPA’s emissions regulations, local governments are leading the fight against climate change.
