EPA revised the National Ambient Air Quality Standards (NAAQS) for Particulate Matter (PM) in March. The state of Kentucky and others filed a lawsuit in the D.C. Circuit arguing that EPA should have considered costs when setting its 2024 NAAQS for PM. We filed an amicus brief explaining that EPA appropriately assessed costs in its separate regulatory impact analysis, that considering regulatory costs would not lead to a less stringent standard, and that there is no history of EPA considering costs when revising the NAAQS.
