An Act Concerning the Use of PFAS in Class B Firefighting Foam

Public Act 21-191, An Act Concerning the Use of PFAS in Class B Firefighting Foam, effective July 13, 2021, implemented a phased ban of the use of firefighting foams containing intentionally-added per- and polyfluoroalkyl substances (PFAS). These foams are typically used for extinguishing Class B flammable liquid and petroleum hydrocarbon fires. Common labels for these foams include AFFF, AR-AFFF, FFFP, AR-FFFP, FP, and FPAR (“Fluorinated Foam”). The Fluorinated Foam ban was rolled out in phases:

Beginning July 13, 2021, the law banned the use of fluorinated foams for training or testing systems.
Beginning October 1, 2021, the law banned all remaining uses of fluorinated foams. Airports and those federally required by law to use such foams were excluded. Chemical plants, oil refineries, and flammable liquid terminal, storage, or distribution facilities were eligible to apply to DEEP for an extension, up to two years, in order to comply with the law.
Beginning October 1, 2023, the law banned airports, unless required by the federal government, from continuing to use fluorinated foams.
Federally required uses will continue to be allowed in Connecticut until prohibited by Federal law or one year after Federal law changes to no longer require such use.

Public Act 21-191 also required DEEP to identify suitable alternative fluorine-free firefighting foam(s) and authorized the State to organize a municipal AFFF "take-back" program. To learn more, visit the Reducing and Preventing Releases of PFAS-Containing Firefighting Foam webpage.

Federally Required Exemptions at Airports and Military Installations

The federal government has historically required certain entities, including military installations and FAA-certified airports, to utilize fluorinated firefighting foams.

The passage of Public Act 21-191 mandated that in the event that federal law no longer required, but did not prohibit, the use of fluorinated foam, previously federally required users in Connecticut would have one year to cease use of such foams. All Connecticut FAA Part 139 airports are therefore prohibited from using AFFF beginning September 19, 2024.

The following are significant federal AFFF-related developments that affect Connecticut airports and military installations:

On March 18, 2024, the Federal Aviation Administration (FAA) issued CertAlert 24-04 to part 139 airports recommending the Department of Defense (DOD) aircraft rescue and firefighting (ARFF) apparatus foam change out guidance.
On March 5, 2024, Department of Defense (DoD) released a memo outlining guidance for changing out foam in aircraft rescue and firefighting (ARFF) apparatus. DOD recommendation is to drain the apparatus, rinse any AFFF-contaminated components, and refill with a DOD-approved fluorine-free foam.
On September 19, 2023, the FAA notified Part 139 airports and industry that there is now at least one fluorine-free foam (F3) that meets DoD’s new military performance-based specifications. The foam is approved, but not required, for use at FAA-certified airports. FAA has messaged that it is acceptable for airports to use both AFFF and F3 until an airport is able to fully transition over to F3.
On May 18, 2023, the Naval Research Laboratory published Fluorine-Free Foam (F3) Application Techniques and Firefighting Tactics.
On May 8, 2023, the Federal Aviation Administration (FAA) coordinated with the Department of Defense (DoD), the U.S. Environmental Protection Agency (EPA) and industry partners to produce the Aircraft Firefighting Foam Transition Plan to assist airports with transitioning to fluorine free foams (F3).
On January 6, 2023, the Department of Defense (DoD) released a new military specification (MIL-PRF-32725) outlining performance-based standards for fluorine-free foam (F3) liquid concentrate fire extinguishing agents intended for use on class B hydrocarbon liquid fuel fires in land-based applications. The specification is approved for use by all DoD departments and agencies.
On December 20, 2019, the National Defense Authorization Act (NDAA) for Fiscal Year 2020 was signed into law, requiring DoD to immediately stop training with AFFF and, with limited exceptions, to phase out overall use of AFFF at military locations by September 30, 2024. To achieve this goal, the NDAA also requires that DoD stop purchasing firefighting foam that contains detectable levels of PFAS for land-based use by October 1, 2023.

Fluorinated Foam Use Extensions at Terminals and Chemical Plants

Pursuant to PA 21-191, Sec. 1(b)(5) (CGS Sec. 22a-903a), chemical plants, oil refineries, and flammable liquid terminal, storage, or distribution facilities were eligible to apply to DEEP for an extension in order to comply with the law. Submission of a Request for Extension of Class B PFAS Firefighting Foam Use Form was required to request any such extension. The request needed to clearly (a) specify in the filing why such an extension is necessary and (b) indicate what containment, treatment, and disposal measures were to be employed to prevent releases of PFAS-containing class B firefighting foam into the environment until compliance could be achieved. Upon review of extension request materials, DEEP granted an extension of up to two years if it was determined that such extension was necessary to remove or repurpose a fire suppression system containing such foam.

The following tables show the PFAS Firefighting Foam extensions granted by DEEP.

All remaining approved extensions expired on October 1, 2023; release of AFFF after October 1, 2023 may therefore result in enforcement action by DEEP.

Owners of systems that self-reported to DEEP that they have converted to fluorine free foams (F3), or otherwise transitioned away from AFFF use, during the extension period are designated "Complete" in the "Facility-Reported Status" column of the tables below. Those facilities with an "In Progress" conversion status have communicated to DEEP that efforts are still underway to remove AFFF from their fire suppression systems.
