Total Pollution Exclusion
Definition
The total pollution exclusion is wording in many general liability policies that removes coverage for injury or damage caused by pollutants, with very few exceptions. So a fuel leak, chemical spill or contamination claim against a property owner is often not covered by general liability.
In Plain English
The standard general liability form already excludes most pollution claims, but it keeps a few narrow exceptions. A total pollution exclusion, usually added by endorsement, removes most of those exceptions too. Cleanup costs are generally excluded either way. Your policy's exact wording controls.
This is why gas stations need separate storage tank liability insurance. It is also why some owners buy pollution legal liability for pollution from past or current uses of a site.
Property policies limit pollution too. They often give only a small additional coverage for pollutant cleanup and removal from your own property.

Example
Hypothetical: an industrial tenant's drums leak solvent into the soil and a neighbor sues the owner. If the owner's general liability has a total pollution exclusion, the claim may be excluded, and only a pollution policy might respond.
What to Watch For
- Ask which pollution exclusion your general liability policy uses.
- Review tenant uses that could create pollution claims, such as auto repair or dry cleaning.
- Consider pollution coverage for fuel, chemical or older industrial properties.
- Require high-risk tenants to carry their own pollution coverage.
