- Bars designating an area as nonattainment for a new or revised air quality standard if the area would meet that standard but for emissions from outside the United States.
- Adds Section 179C, under which sanctions and fees do not apply to certain severe or extreme ozone and serious particulate matter areas when the state shows the shortfall stems from outside emissions, exceptional events, or mobile sources beyond state control.
- Requires states to renew this demonstration at least once every 5 years.
- States that the exemption does not relieve states, areas, or sources of their duty to take steps to attain the standards.
