Particulate Matter 2.5 Legal Petition for Review

Environment America and partners filed a lawsuit challenging EPA's decision to flatline particulate matter standards.


 Environment America, along with ten other public interest organizations, filed a lawsuit Tuesday in the U.S. Court of Appeals for the D.C. Circuit opposing the Trump administration’s unlawful decision to bypass updating the National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM 2.5).
