EPA Administrator Andrew Wheeler says the agency is proposing

to retain current ozone requirements that were set in 2015.

He says from 2017 to 2019, ozone concentrations across the

country fell four percent.

Wheeler says a recent Harvard study, which suggests breathing more polluted air after many years could worsen the effects of COVID-19, has not been peer-reviewed and is withholding judgment until then.
