The State of California, along with ten other states, the District of Columbia, Harris County (Texas), and the City of New York, filed suit against EPA Administrator Lee Zeldin on April 24, 2026, in the U.S. District Court for the Northern District of California. The plaintiffs alleged that the EPA promulgated revised 2024 National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM2.5) on February 7, 2024, establishing a statutory deadline of February 7, 2026, for area designations. However, the EPA allegedly failed to meet this deadline, violating Section 107(d)(B) of the Clean Air Act. The plaintiffs claimed this failure delayed critical public health protections from fine particulate matter pollution and deprived state and local governments of necessary regulatory tools to control air pollution. They sought declaratory and injunctive relief, including an order requiring the EPA to promulgate designations within 150 days, as well as attorneys' fees and costs.
