Key Terms to Know
Absolute Pollution Exclusion
The standard GL pollution exclusion that eliminates coverage for virtually all pollutant-related claims — including mold, asbestos, diesel fumes, and chemical releases. This is why standalone pollution liability is essential.
Contractors Pollution Liability (CPL)
Specifically covers contractors for pollution claims arising from their operations — disturbing asbestos during renovation, fuel spills from equipment, mold discovered during HVAC work.
Sudden vs Gradual
"Sudden and accidental" pollution exclusions in older GL policies were more lenient — covering unexpected releases. Most modern absolute exclusions cover neither sudden nor gradual releases.
Site Pollution
Covers contamination on sites owned or operated by the insured — separate from CPL, which covers third-party sites.
