Matching pollution liability: how the comparison works

QUICK ANSWER

Pollution liability pays for the cleanup, the injury and the property damage from a release of something general liability calls a pollutant: fuel, solvents, fertiliser, mold, asbestos, bacteria, fumes, effluent. Contractors buy it on a contractors pollution form; businesses with a site buy it on a site form. Carriers quote it on the materials handled, the work done and the history of the site. CoverMatch compares the forms, the materials named and the triggers side by side.

01 / WHAT UNDERWRITERS ASK
  • What pollutants the business handles, hauls, applies or disturbs
  • Whether the work is at client sites (contractors form) or your own premises (site form)
  • Materials and certifications for remediation work
  • Fuel storage, tanks and any spill history
  • Transportation and disposal practices
  • Contracts that require the coverage and the limits they name
02 / WHAT MOVES THE PRICE
  • MaterialsMold, asbestos, lead and fuels are rated by the exposure each creates.
  • OperationsRemediation, excavation, painting and lawn application carry different release potential.
  • Site historyKnown contamination on a site raises the quote or is excluded.
  • Limits and claims-made versus occurrenceOccurrence forms cost more and cover more; claims-made forms depend on continuity.
  • TransportationHauling pollutants adds a transit exposure that some forms price separately.
Direction only — the carriers' quotes carry the figures.
03 / HAVE READY
  • A list of chemicals, fuels and materials used or disturbed, with safety data sheets
  • Certifications and licences for remediation, applicators or tank operations
  • Contracts from clients or municipalities that require pollution coverage
  • Any spill, release or environmental correspondence from the last five years
  • Your current general liability declarations, to show the exclusion being filled

What pollution liability responds to

A release that causes bodily injury, property damage or the cost of cleaning up, whether sudden or gradual, from your work or your site. The policy fills the hole the pollution exclusion leaves in general liability, and for remediation contractors it is the primary policy rather than a supplement.

How CoverMatch compares the quotes

Form (contractors or site), occurrence or claims-made with the retroactive date, the pollutants named or excluded, transportation and disposal coverage, mold and asbestos treatment, limits and deductible, and defence inside or outside. The AI summary names the differences; the licensed agent is one tap away.

What to watch for

A remediation contractor with mold excluded on its pollution policy, a site form with the known condition excluded, and a claims-made form bought to replace an occurrence one without a retroactive date to match.

Questions people actually ask

Doesn't general liability cover a spill?

Almost never. The pollution exclusion on standard forms removes releases of fuel, chemicals, fumes and mold, with narrow exceptions. Pollution liability is written to answer exactly what the exclusion removes.

What is the difference between contractors pollution and site pollution?

Contractors pollution covers releases from your operations at other people's sites, wherever you work. Site pollution covers releases at a location you own or operate, including gradual contamination and cleanup orders. Some businesses need both.

Is mold a pollutant?

Under most general liability forms, yes, through the fungus exclusion. Pollution policies that name mold cover it; policies that do not, do not. The comparison shows which.

Occurrence or claims-made?

Occurrence covers releases during the policy period whenever the claim arrives; claims-made covers claims made during the period and depends on keeping coverage continuous. The comparison labels each quote.
