The Trump administration on Wednesday took a step toward rolling back a rule intended to limit smokestack emissions from heavy industries, notably coal-fired power plants, which burden air quality in downwind areas of neighboring states. This so-called Good Neighbor rule is among several regulations that EPA Administrator Lee Zeldin aims to review or repeal. A Supreme Court ruling in 2024 had previously restricted the EPA's ability to enforce this rule, which was designed to prevent significant air pollution from crossing state lines. Under the new proposal, eight states will have the autonomy to determine their own plans for regulating ozone air pollution without federal approval, as stated by the EPA. This is a marked departure from the Biden administration's previous actions which had disapproved state plans for insufficient control over ozone emissions. Environmental advocates have criticized this shift, claiming it prioritizes industrial interests over public health and could lead to worse air quality across state lines. They argue that relaxing these rules allows polluting states to escape accountability while risking the health and well-being of residents in neighboring areas.
