Does My General Liability Cover Pollution? The Exclusion Explained

It's the question that catches contractors off guard at the worst possible time: a spill or a fume claim comes in, and the general liability carrier denies it. The reason is a clause that's been in standard policies for decades — the absolute pollution exclusion.

What the exclusion says

Most commercial general liability (CGL) policies contain language excluding bodily injury or property damage 'arising out of the actual, alleged or threatened discharge, dispersal, seepage, migration, release or escape of pollutants.' In plain terms: if a contaminant is involved, the claim is excluded.

Why it exists

Insurers added the exclusion to carve environmental risk out of general liability and move it into specialized policies. It's not a loophole or an oversight — it's deliberate, and it's nearly universal. Some policies include a narrow 'hostile fire' or limited exception, but you can't rely on those for operational pollution.

What it actually removes

Fuel and fluid spills from your equipment.

Silt and sediment runoff from a graded or excavated site.

Fumes and vapors from coatings, solvents, and adhesives.

Dust containing contaminants (silica, lead, asbestos).

Contaminated soil disturbed or spread during the work.

Each of these is a routine part of construction — and each is excluded from your CGL.

How to close the gap

Contractors pollution liability (CPL) is purpose-built to respond where the exclusion applies. It covers third-party bodily injury, property damage, and cleanup from pollution conditions caused by your operations. For site-based exposure, site pollution liability adds location-tied coverage; for hauling, transported-pollutants coverage applies.

Don't assume — verify
