Understanding Absolute Pollution Exclusion in 2024

Absolute pollution exclusion is a critical clause in commercial liability insurance policies that specifically excludes coverage for pollution arising from routine business activities. Since its rise in popularity post-1986, following regulatory changes and costly pollution lawsuits, this clause has become a standard feature in comprehensive general liability (CGL) policies.

Key Highlights

• Absolute pollution exclusion removes insurer liability for pollution claims tied to normal business operations.
• It emerged as a response to increasing environmental lawsuits in the 1980s.
• This exclusion differs from total pollution exclusion, which eliminates all pollution-related liabilities.
• Several important exceptions exist, allowing coverage for specific pollution incidents both on and off insured premises.

How It Functions in Commercial Insurance

The clause was introduced amid growing environmental regulations such as the Resource Conservation and Recovery Act and the Comprehensive Environmental Response, Compensation, and Liability Act. These laws triggered lawsuits against polluting companies, exemplified by the Montrose Chemical Corp. case, which compelled insurers to reconsider their exposure to pollution claims.

Insurers argued that pollution was often gradual rather than "sudden and accidental," leading to the establishment of absolute pollution exclusions to limit their liability.

Despite the term "absolute," these exclusions allow coverage for certain incidental pollution events, categorized under six key exceptions related to the insured property and other locations where pollutants may be introduced.

Fast Fact

The absolute pollution exclusion removes previous exceptions for accidental and sudden pollution, tightening coverage limitations.

Special Considerations in 2024

While often called a broad pollution exclusion, absolute pollution exclusion still permits coverage in particular cases. In contrast, total pollution exclusion offers no coverage for pollution-related bodily injury or property damage.

Definitions of pollution can vary, and courts may influence interpretations, especially concerning pollutants like lead paint or asbestos.

Common Exceptions to Absolute Pollution Exclusion

Exceptions fall into two categories: incidents occurring on the insured premises and those happening elsewhere.

• On Premises:
  • Building Heating Equipment: Coverage applies if injury results from heating equipment by-products like smoke or fumes, excluding air conditioning-related equipment.
  • Owner as Additional Insured: Covers injury or damage at off-premises locations when the insured acts as a contractor.
  • Hostile Fire: Applies to damage caused by uncontrollable fires spreading beyond their origin, such as smoke damage from a tire fire affecting nearby neighborhoods.
• Away from Premises:
  • Mobile Equipment: Covers unintentional pollutant releases from mobile equipment, like diesel spills from vehicle accidents.
  • Operations Within Building: Protects against pollutants introduced during contracted work, such as harmful fumes from paint thinners.
  • Hostile Fire: Similar coverage for fire-related damage occurring at offsite work locations.

Conclusion: What Businesses Should Know in 2024
