Agriculture PFAS Liability Protection Act of 2023

This bill exempts agricultural operations from liability under the federal CERCLA law for releases of specific PFAS chemicals used in farming. It directly affects farmers and agricultural businesses (defined as "protected entities") who produce or harvest crops, shielding them from lawsuits or cleanup costs related to covered PFAS substances. The exemption applies to non-volatile PFAS hazardous substances (excluding gases) used in agricultural practices, but does not protect against liability for gross negligence or willful misconduct. The law changes existing environmental liability rules to specifically exclude routine agricultural activities involving these chemicals.
