Contractors pollution liability (CPL) insurance covers claims that your work released or disturbed something harmful, such as fuel, mold, sewage, silica dust, lead paint, asbestos or chemicals. Those claims can involve injury to someone, damage to property or a cleanup bill. Those are the claims a general liability policy’s pollution exclusion is written to leave out.

This page explains how the pollution exclusion works, what a CPL policy generally covers and how to compare policies. It’s written for Florida contractors whose work touches soil, water, fuel, chemicals or older buildings. It’s also for any contractor whose contracts ask for pollution coverage.

Why general liability leaves a gap

Standard commercial general liability (CGL) policies include a pollution exclusion. On the standard ISO form, “pollutants” are defined broadly as any solid, liquid, gaseous or thermal irritant or contaminant, including smoke, vapor, soot, fumes, acids, alkalis, chemicals and waste. The exclusion generally removes coverage for injury or damage from the actual, alleged or threatened release of pollutants in a list of situations that covers most contractor exposures, such as releases at your premises, from waste and from materials you or your subs bring to a job site. It also removes cleanup costs that a government agency or a regulation requires.

The standard exclusion has a few narrow exceptions, such as certain fumes from materials a contractor brings into a building and certain releases of fuels or fluids needed for mobile equipment to operate. Many contractor policies replace it with broader wording, often called a total pollution exclusion, that removes most or all of those exceptions. Some policies also exclude or limit mold, lead, asbestos or silica separately.

How Florida courts have read the exclusion

General information about a published court decision, not legal advice. How a court treats a specific claim depends on the policy language and the facts.

In a 1998 decision, the Florida Supreme Court held that the pollution exclusion in the policies it reviewed was clear and unambiguous, and it declined to limit the exclusion to environmental or industrial pollution. The court decided two cases together. In one, ammonia spilled from a blueprint machine while equipment was being moved inside a two-story commercial building, and people claimed injuries from the fumes. In the other, insecticide being sprayed on a citrus grove from a helicopter splashed onto two men standing on adjacent property. The exclusion applied in both. The practical point for contractors: in Florida, don’t count on a general liability policy to cover a release just because it happened indoors or seems small.

Pollution exposures by trade

Work Examples of pollution exposures
HVAC Refrigerant releases, mold tied to condensate and duct moisture, disturbing asbestos in older buildings
Plumbing Sewage backups, mold after water damage, fuel and chemical releases
Site prep and underground utility Fuel spills from equipment, disturbing contaminated soil, sediment and runoff, striking an underground tank or line
Concrete Silica dust from cutting and grinding, washout water, curing compounds and sealers
Road and paving Fuel and asphalt releases, milling dust, runoff
Pools Chlorine and acid spills or fumes on service routes and at the shop
Pest control Pesticide drift, misapplication and exposure claims
Renovation and interior work Lead paint dust in older buildings, asbestos in flooring, insulation and pipe wrap, mold behind walls

Rules that raise the stakes

Federal and state rules don’t create insurance coverage, but they show where regulators see pollution risk in construction, and a violation can make a claim harder to defend:

  • Lead paint. EPA’s Renovation, Repair and Painting Rule requires firms paid to disturb painted surfaces in homes, child care facilities and preschools built before 1978 to be certified and to use lead-safe work practices.
  • Asbestos. EPA’s asbestos NESHAP rules require a thorough inspection before demolition or renovation of regulated facilities, which generally excludes residential buildings with four or fewer units, and set work practices for that work.
  • Silica. OSHA’s construction silica standard sets exposure limits and control methods for tasks like cutting, grinding and drilling concrete and masonry.
  • Stormwater. In Florida, construction that disturbs one acre or more, or is part of a larger plan that will, and discharges stormwater to surface waters or a storm sewer system generally needs coverage under the Florida Department of Environmental Protection’s construction generic permit.
  • Fuel storage. Storing fuel or oil above certain amounts can require a spill prevention plan under EPA’s SPCC rule.
  • Mold. EPA publishes guidance on mold remediation in commercial buildings. Contracts sometimes make contractors responsible for mold tied to their work.

What a CPL policy generally covers

CPL policies aren’t standardized, so terms vary by insurance company. Depending on the policy, coverage can include:

  • Bodily injury and property damage to others from a pollution condition caused by your operations
  • Cleanup costs, including cleanup required by a government agency
  • Defense costs, which may be inside or outside the limit
  • Completed operations, for releases discovered after the job is finished
  • Transported cargo and disposal sites, sometimes as options
  • Mold, lead and asbestos, sometimes included, sometimes limited by a sublimit and sometimes excluded

How CPL is written

  • Occurrence or claims-made. Both forms are available. On a claims-made policy, the retroactive date decides how far back your work is covered. See our claims-made explainer.
  • Standalone or combined. CPL can be a separate policy, an endorsement or combined with general liability or contractors professional liability.
  • Practice or project. Most contractors buy CPL for all of their operations. Large or high-risk jobs sometimes use a project-specific policy.
  • Additional insureds. General contractors and owners often ask to be added as additional insureds on your CPL, the same way they do on general liability.
  • Your subs. Check whether the policy covers work by your subcontractors and whether you need to require CPL from them.

Questions to ask before you buy or renew

  • What does the pollution exclusion on my general liability say, and are mold, lead, asbestos or silica excluded separately?
  • Do any of my contracts require pollution coverage, a specific limit or additional insured status on it?
  • Is the CPL occurrence or claims-made, and if claims-made, what is the retroactive date?
  • Are defense costs inside or outside the limit?
  • Does it cover mold, lead and asbestos? At what limit?
  • Does it cover completed operations, transported materials and disposal sites?
  • Does it cover work my subcontractors do for me?

Frequently asked questions

Doesn’t my general liability cover a fuel spill?

Probably not. Standard general liability policies exclude most pollution claims, and the Florida Supreme Court has held that the standard pollution exclusion is clear and isn’t limited to environmental pollution. A few narrow exceptions exist on the standard form, and many contractor policies remove them.

Is mold a pollution claim?

It depends on the policy. Some general liability policies treat mold under the pollution exclusion, some exclude it separately and some limit it. CPL policies may include, sublimit or exclude mold.

Who needs contractors pollution liability?

Contractors whose work involves soil, water, fuel, chemicals, sewage, mold or older buildings. Contractors whose contracts require it need it too. That includes many site work, plumbing, HVAC, paving, pool, concrete, pest control and renovation businesses.

Is CPL occurrence or claims-made?

It can be either, depending on the insurance company. If it’s claims-made, keep your retroactive date when you renew and think about a tail if you close or sell the business.

Can my general contractor be added to my pollution policy?

Often, yes. Many CPL policies can add additional insureds when a written contract requires it. Check the endorsement wording.
