Lawsuit Launched Challenging EPA's Failure to Update Air Pollution Emission Standards for Soot, Sulfur, Nitrogen
Environmental groups filed a formal notice today of their intent to sue the Environmental Protection Agency to force it to update limits on soot, sulfur and nitrogen air pollution. The standards must be reviewed and updated every five years to account for the latest science on the risks and threats to human health and the environment. But the agency last updated any of the standards for the three pollutants back in 2013.
