Pollution Liability

Environmental pollution liability insurance

Here's a costly surprise for a lot of Michigan business owners: most general liability policies carry an absolute pollution exclusion, so a contamination loss isn't covered at all. Being uninsured for pollution is one of the most common coverage gaps we see — and dedicated environmental coverage closes it, from cleanup costs to legal defense.

The gap most businesses don't know they have

Pollution isn't just an oil spill or a factory smokestack. It's a leaking underground tank, fumes from a paint booth, mold from a failed HVAC system, runoff from a job site, or chemicals released during cleaning. Because standard general liability policies exclude these losses, the cleanup, third-party claims, and defense costs can land entirely on the business — and they add up fast. Environmental pollution liability is the coverage built to respond.

Who should consider it

  • Contractors and tradespeople
  • Auto service shops and dealers
  • Food & beverage and hospitality
  • Farms and agribusiness
  • Manufacturers and warehouses
  • Property owners with tanks or older systems

FAQ

Pollution liability, answered

What is pollution liability insurance?

It covers pollution-related losses — cleanup costs, bodily injury and property damage, legal defense, and transport or disposal — that most standard business policies exclude. Coverage is subject to underwriting.

Doesn’t my general liability policy cover pollution?

Usually not. Most general liability and property policies contain a pollution exclusion, which leaves a gap many businesses don’t realize they have until a claim happens.

What kinds of businesses need pollution coverage?

Contractors and tradespeople, auto shops and dealers, food & beverage and hospitality, farms and agribusiness, manufacturers and warehouses, and property owners with tanks or older systems.

What counts as a “pollution” claim?

It can range from a fuel or chemical spill to carbon monoxide, mold, or contamination from your operations or premises — events that harm people, property, or the environment.

Is pollution coverage expensive?

It varies by industry and exposure, and for many businesses it’s an affordable way to close a serious gap. We’ll help you size coverage to your real risk.
