Airports PFAS Liability Protection Act

This bill protects airport sponsors (like public airports or joint-use facilities) from federal environmental liability claims related to PFAS chemicals used in firefighting foam. It specifically exempts them from costs under the federal environmental law (CERCLA) if the PFAS release resulted solely from using the foam as required by the FAA for safety compliance and following FAA guidelines. The exemption does not apply if the airport sponsor acted with gross negligence or willful misconduct in using the foam. This law directly affects airports that use FAA-mandated firefighting foam but does not shield them from liability for reckless conduct.
