The Good Neighbor Plan is part of the EPA’s effort to curb air pollution that crosses state lines, particularly nitrogen oxide (NOₓ) emissions from industrial sources. This plan proposes stricter NOₓ emission limits for various industries, including natural gas pipelines, cement manufacturing, steel production, glass manufacturing, and chemical processing. These measures aim to help downwind states meet national air quality standards for ozone pollution by reducing harmful emissions at the source. The plan targets high-emitting equipment and large boilers with specific limits to protect public health and the environment.
