EPA finalized its “Good Neighbor Plan” to reduce the occurrence of smog (ground-level ozone) in states downstream from nitrogen oxide-producing power plants in upstream states. Exposure to smog can cause respiratory issues, and exacerbate asthma and other lung diseases, particularly in children and older adults. Smog exposure also disproportionately affects people of color, low-income families, and other vulnerable populations. The plan was anticipated to cause emission reductions for environmental justice communities. Authorized by the Clean Air Act’s “good neighbor” provisions, EPA’s rule is designed to improve air quality in states that are adversely impacted by pollution produced in 23 states.
