Good Neighbor Plan for 2015 Ozone NAAQS

On March 15, 2023, the U.S. Environmental Protection Agency (EPA) issued its final Good Neighbor Plan, which secures significant reductions in ozone-forming emissions of nitrogen oxides (NOX) from power plants and industrial facilities. This action will save thousands of lives and result in cleaner air and better health for millions of people living in downwind communities.

The Good Neighbor Plan ensures that 23 states meet the Clean Air Act’s “Good Neighbor” requirements by reducing pollution that significantly contributes to problems attaining and maintaining EPA’s health-based air quality standard for ground-level ozone (or “smog”), known as the 2015 Ozone National Ambient Air Quality Standards (NAAQS), in downwind states.
