In its September 5, 2025, opinion in SSM Litigation Group v. EPA, the U.S. Court of Appeals for the D.C. Circuit overturned EPA's 2023 removal of the Title V affirmative defense for emergencies.

The Court found that EPA's justifications for removing the defense, namely that:

  • the defense unlawfully encroached on the judiciary's role under the Clean Air Act to assess penalties for violations of emission limitations, and
  • the defense is effectively an exemption from applicable emission limitations and therefore renders those limitations not "continuous" in violation of the Clean Air Act,

were erroneous, with the court reversing the 2023 recission of the defense.

Restoring the Title V emergency defense will keep permittees who exceeded emission limits as a result of emergencies from having to rely on agency or judicial discretion to avoid penalties for violations caused through no fault of their own.

Federal Court Enjoins Sweeping New Mexico PFAS Labeling Obligations

The world’s broadest PFAS labeling obligation has been put on hold. On September 16, 2026, the U.S. District Court for the District of New Mexico granted an industry motion for a preliminary injunction against labeling requirements New Mexico enacted earlier this year. The court concluded that industry’s challenge to the labeling requirements was likely to succeed on the merits. The requirements were set to go into effect for products manufactured after January 1, 2027. Although further legal battles may remain, the program appears unlikely to take effect as scheduled.

This decision establishes that these "forever chemicals" can now form the basis for federal Superfund response actions and cost-recovery claims, while leaving broader questions about PFAS regulation and enforcement still in motion.
