EPA finalized a rule designating two PFAS substances as hazardous substances under CERCLA. This designation will allow EPA to impose CERCLA’s enforcement tools on polluters and require those polluters to pay for the investigation and cleanup of PFAS. The rule further requires that any federal entity seeking to sell or transfer their property must disclose the storage, release, or disposal of PFOA or PFOS on the property, and must guarantee completion of cleanup or plans for cleanup in the future. Based on EPA’s demographic analysis, it found that the rule is likely to reduce disproportionate and adverse effects on communities with EJ concerns. The rule went into effect on July 8, 2024.
