States could avoid air quality penalties for pollution coming from outside the U.S.
States could avoid air quality penalties for pollution from outside the U.S., natural events, or uncontrollable vehicles. The bill would also clarify that all foreign emissions, natural or human-caused, count when assessing air quality.
Today, states can be penalized or have areas designated as having unhealthy air even if pollution largely comes from outside the U.S., and it's unclear if natural foreign emissions count. After this bill, states could avoid these designations and penalties if they prove the pollution is from outside the U.S. (including natural sources), exceptional events, or uncontrollable vehicle emissions.
