EPA initiates new review of the Ozone National Ambient Air Quality Standards

Green Car Congress

AUGUST 22, 2023

The Environmental Protection Agency (EPA) announced a new review of the Ozone National Ambient Air Quality Standards (NAAQS). EPA established the current standards at a level of 70 parts per billion in 2015 and retained them in 2020, after concluding that there was little new information to suggest the need for revision.
