Trump’s EPA Abandons Defense of National Soot Standard That Saves Lives - CleanTechnica

The Trump administration’s Environmental Protection Agency (EPA) has taken the unprecedented step of abandoning its defense of the strengthened national standards for fine particulate matter (PM2.5), commonly known as soot. These standards, part of the National Ambient Air Quality Standards (NAAQS) under the Clean Air Act, were tightened last year to reduce the allowable annual soot concentration from 12 to 9 micrograms per cubic meter. This change was based on extensive scientific evidence and expert recommendations, aiming to protect public health by preventing thousands of premature deaths and delivering cleaner air, especially for communities near highways, factories, and power plants. Despite the projected health benefits and the importance of the soot standard, the EPA has filed with the U.S. Court of Appeals for the D.C. Circuit to strike down the rule. Environmental advocates, including the Sierra Club, have condemned this move as a dangerous betrayal of the EPA’s mission to protect communities from toxic pollutants. They argue that the rollback favors fossil fuel interests at the
