Sterigenics U.S., LLC v. National Union Fire Insurance Company of Pittsburg

Plain English (For Everyone)

Your home insurance likely won't cover pollution damage, but this case is about a business's special insurance. A company that sterilizes medical equipment won't have its insurance policy's pollution exclusion apply to its normal, regulated emissions of a chemical called ethylene oxide. The court decided the exclusion was meant for accidental environmental disasters, not everyday business operations.

For Legal Practitioners

The Seventh Circuit affirmed summary judgment for the insured, holding that the 'absolute pollution exclusion' did not bar coverage for ethylene oxide emissions from a sterilization facility. The court reasoned that the exclusion's operative terms 'discharge, dispersal, release, or escape' contemplate traditional environmental pollution events, not routine, regulated operational emissions. This ruling limits the application of absolute pollution exclusions to circumstances beyond the ordinary course of business.

For Law Students

The Seventh Circuit held that such exclusions do not apply to routine, regulated emissions from industrial facilities, even if the emitted substance is a pollutant. The court's interpretation focuses on the intended meaning of 'discharge, dispersal, release, or escape' as referring to accidental environmental contamination.

Scenario: You own a manufacturing plant that emits regulated substances as part of its normal operations, and your business insurance policy has an 'absolute pollution exclusion.'

Your Rights: You have the right to expect coverage for claims arising from these normal operational emissions, as this ruling suggests such exclusions are intended for accidental environmental damage, not routine business activities.

What To Do: Review your insurance policy carefully, consult with your insurance broker and legal counsel to understand the specific wording and how this ruling might apply to your situation, and ensure your operational permits and environmental compliance are up-to-date.

Is it legal for a business to emit ethylene oxide?

Depends. Ethylene oxide (EtO) is a hazardous air pollutant, and its emission is heavily regulated by federal and state environmental agencies like the EPA. Businesses using EtO must comply with specific emission standards and permitting requirements. While it is legal to emit EtO under strict regulatory controls, exceeding those limits or operating without proper permits is illegal.

This applies nationwide under EPA regulations, with potential for stricter state-level rules.

For Businesses with environmental insurance policies

This ruling narrows the scope of 'absolute pollution exclusions,' potentially making coverage available for claims arising from routine operational emissions that were previously thought to be excluded. Businesses should re-evaluate their insurance coverage and consult with legal counsel.

For Environmental regulators and public health advocates

The ruling does not change the regulatory requirements for businesses emitting hazardous substances like EtO. It primarily affects the allocation of risk between businesses and their insurers. However, it may indirectly encourage insurers to scrutinize policy language more closely regarding operational emissions.
