The Pollution Exclusion That Killed a Contractor

Every standard Commercial General Liability policy in the United States contains an absolute pollution exclusion. Every single one. It's been standard since 1986, and it means exactly what it says: if a claim arises from the discharge, dispersal, seepage, migration, or release of pollutants, your CGL policy does not respond.

For most businesses, this exclusion is an academic concern. For government contractors performing work at federal sites — especially DOE environmental cleanup facilities, legacy contamination sites, and installations with decades of industrial history — it is an existential threat.

Consider the work. Environmental remediation contractors handle hazardous materials daily. They excavate contaminated soil. They manage asbestos abatement. They transport and dispose of regulated waste. They work in and around structures with known environmental contamination stretching back to the Manhattan Project. Every day on the job is a day spent handling materials that trigger the pollution exclusion.

Now consider what happens when something goes wrong. A containment failure during soil remediation releases contaminants into a neighboring water supply. A worker is exposed to hazardous dust that wasn't properly controlled. A transport vehicle is involved in an accident that releases regulated materials onto a public roadway.

The contractor calls their broker. The broker calls the carrier. The carrier points to the pollution exclusion. Claim denied.

The defense costs alone can reach seven figures. The liability — bodily injury, property damage, cleanup expenses, regulatory fines — can reach eight. And the contractor, who believed their CGL policy would protect them, discovers that the most fundamental risk in their operation was never covered at all.

This is not a hypothetical. This happens. It happens because brokers don't understand the work their clients perform, and they don't examine whether the coverage matches the exposure. They see "general liability" on the FAR requirement list, they place a standard CGL policy, and they move on.

Contractors Pollution Liability — CPL — exists specifically to fill this gap. It covers third-party bodily injury and property damage from pollution events. It covers defense costs. It covers cleanup expenses. It can be structured to cover both sudden and gradual pollution events, and it can be combined with professional liability to create comprehensive environmental coverage for firms performing technical services at contaminated sites.

If your firm performs any work at DOE environmental cleanup sites, legacy contamination facilities, or installations with known environmental history, CPL isn't optional coverage. It's the only thing standing between your firm and an uninsured claim that can end your business.

The pollution exclusion in your CGL policy isn't a technicality. It's a wall. And most brokers never tell you it's there.
