What Insurance Covers Pollution?

Environmental or pollution liability coverage is generally the coverage line to examine for specified cleanup costs and third-party claims arising from pollution. The policy responds only when its insuring agreement, definitions, and covered-cause requirements are satisfied; the line name by itself does not establish that a loss qualifies. Standard CGL policies generally exclude most pollution damage. Environmental liability may cover specified cleanup and third-party claims, with narrow terms and exclusions.

Common exceptions include exclusions, sublimits, deductibles, and conditions specific to the insured property, claimant, or event. Different forms can treat closely related losses differently, so a quote summary or certificate is not enough to establish the complete terms. The policy and endorsements control.

For this exposure, check pollutant definitions, known conditions, scheduled locations, and claims-made dates. Ask the broker to point to the applicable grant and exception in the actual form, and verify who is insured, the policy period, limits, and claim-notice steps.
