Summary: A new type of exclusionary endorsement is being made available under the ISO program to address exposures of PFAS chemicals. This is an early introduction to the filing, as the endorsements will not be available until at least May, 2023.
PFAS is the abbreviation for perfluoroalkyl and polyfluoroalkyl substances, which are described by the National Institute of Environmental Health Sciences (NIEHS) as a "large, complex, and ever-expanding group of manufactured chemicals that are widely used to make various types of everyday products." According to the Interstate Technology Regulatory Council (ITRC), some industries and products that incorporate the use of PFAS include, but are not limited to, automobiles, pesticides, cosmetics, food processing, textiles, furniture and household products. While potential health impacts that exposures to PFAS could lead to are still being researched and thus remain uncertain, they have come under scrutiny due at least in part to their environmental presence, because they:
- do not break down in the environment,
- can move through soils and contaminate drinking water sources,
- build up (bioaccumulate) in fish and wildlife.
The CDC has more information on PFAS under their National Biomonitoring Program, contained in this Fact Sheet. The substances are found in rivers and lakes, and also in many types of land and water animals. .
There are three endorsements that attach to various coverage parts. The forms are explained below.
CG 40 32 Exclusion – Perfluoroalkyl And Polyfluoroalkyl Substances (PFAS)
C. The following definition is added to the Definitions Section:
"Perfluoroalkyl or polyfluoroalkyl substances" means any:
- Chemical or substance that contains one or more alkyl carbons on which hydrogen atoms have been partially or completely replaced by fluorine atoms, including but not limited to:
- Polymer, oligomer, monomer or nonpolymer chemicals and their homologues, isomers, telomers, salts, derivatives, precursor chemicals, degradation products or by-products;
- Perfluoroalkyl acids (PFAA), such as perfluorooctanoic acid (PFOA) and its salts, or perfluorooctane sulfonic acid (PFOS) and its salts;
- Perfluoropolyethers (PFPE);
- Fluorotelomer-based substances; or
- Side-chain fluorinated polymers; or
2. Good or product, including containers, materials, parts or equipment furnished in connection with such goods or products, that consists of or contains any chemical or substance described in Paragraph C.1.
Analysis:
CG 40 32 is for use with the CGL coverage part, and in brief is a broad exclusion precluding coverage for bodily injury, property damage and personal and advertising injury related exposures associated with the PFAS definition, including any loss, cost or expense arising out of abating, testing for, monitoring, cleaning up, or other related activities, of PFAS by any insured or by any other person or entity.
Even though paragraph C, which adds to the Definition section, is last in the endorsement, it is shown first in this analysis for convenience, since the exclusion is tied directly to these added definitions.
Note the application of the word 'any' as it pertains to perfluoroalkyl or polyfluoroalkyl substances. This broadens the definition to include those substances that may contain even only the slightest number or amount of the described alkyl carbons, and is not limited to those that are named. This is what we would generally term a 'total' or 'absolute' exclusion.
A. The following exclusion is added to Paragraph 2. Exclusions of Section I – Coverage A – Bodily Injury And Property Damage Liability:
2. Exclusions
This insurance does not apply to:
Perfluoroalkyl And Polyfluoroalkyl Substances
- "Bodily injury" or "property damage" which would not have occurred, in whole or in part, but for the actual, alleged, threatened or suspected inhalation, ingestion, absorption, consumption, discharge, dispersal, seepage, migration, release or escape of, contact with, exposure to, existence of, or presence of, any "perfluoroalkyl or polyfluoroalkyl substances".
- Any loss, cost or expense arising, in whole or in part, out of the abating, testing for, monitoring, cleaning up, removing, containing, treating, detoxifying, neutralizing, remediating or disposing of, or in any way responding to or assessing the effects of, "perfluoroalkyl or polyfluoroalkyl substances", by any insured or by any other person or entity.
B. The following exclusion is added to Paragraph 2. Exclusions of Section I – Coverage B – Personal And Advertising Injury Liability:
- Exclusions
This insurance does not apply to:
Perfluoroalkyl And Polyfluoroalkyl Substances
-
"Personal and advertising injury" which would not have taken place, in whole or in part, but for the actual, alleged, threatened or suspected inhalation, ingestion, absorption, consumption, discharge, dispersal, seepage, migration, release or escape of, contact with, exposure to, existence of, or presence of, any "perfluoroalkyl or polyfluoroalkyl substances".
-
Any loss, cost or expense arising, in whole or in part, out of the abating, testing for, monitoring, cleaning up, removing, containing, treating, detoxifying, neutralizing, remediating or disposing of, or in any way responding to or assessing the effects of, "perfluoroalkyl or polyfluoroalkyl substances", by any insured or by any other person or entity.
Analysis:
Paragraph A. of the endorsement adds the PFAS exclusion to preclude coverage for bodily injury and property damage liability, while Paragraph B. adds the exclusion to preclude coverage fro personal and advertising injury liability. As mentioned earlier, the exclusion is broad encompassing and reads similar to the pollution exclusion in the general liability form, except this exclusion applies to "perfluoroalkyl or polyfluoroalkyl substances".
When attached to policies that do not apply to liability arising out of PFAS, the endorsement will result in a coverage reduction. It must always be shown to be a reduction in coverage whenever a new exclusion is added that was not previously on the policy, or if not otherwise limited or excluded. Even if there is no intent to provide the coverage if it isn't excluded, its covered. This has happened in the past with exposures such as asbestos and pollution, prior to the exclusions being added, and it is happening to some extent now with silent cyber when there is no specific exclusion on the policy.
CG 34 95 Exclusion – Perfluoroalkyl And Polyfluoroalkyl Substances (PFAS)
This endorsement is identical to CG 40 32, except that this endorsement can be attached to either the Owners and Contractors Protective Liability Coverage Part or the Products/Completed Operations Liability Coverage Part.
CG 34 96 Exclusion – Perfluoroalkyl And Polyfluoroalkyl Substances (PFAS)
This endorsement is identical to CG 40 32, except that this endorsement can be attached to the Railroad Protective Liability Coverage Part.
