A U.S. appeals court turned down an effort by business groups to overturn federal clean-air standards, Reuters reported. An industrial coalition filed a lawsuit to overturn the Environmental Protection Agency (EPA) 1997 pollution standards on ozone concentrations and soot particles. Under the court’s decision, EPA would be the agency delegated the responsibility of regulating pollution levels for smog and particulate matter nationwide. According to EPA estimates, implementing the rules would prevent 15,000 premature deaths, 350,000 cases of asthma, and 1 million cases of decreased lung function in children. Three states (Ohio, Michigan, and West Virginia) sided with the industry group in its fight to overturn the clean-air standards.
