Coverage Guide

Spill remediation and pollution cleanup protection for tanker and hazmat carriers

Optional — Often required by contract for fuel, chemical, and hazmat carriers

What Does Environmental Liability Cover?

Environmental impairment liability (EIL) — also called pollution liability — covers the cost of cleaning up fuel, chemical, or hazardous material spills that contaminate soil, groundwater, or air. Standard commercial auto and general liability policies typically exclude pollution cleanup costs. A single diesel spill can cost $50,000–$500,000 in remediation; a chemical spill can cost millions.

Who Needs Environmental Liability?

Fuel tanker operators, chemical haulers, hazmat carriers, and anyone transporting materials that are classified as pollutants under environmental law. Even some seemingly ordinary cargo — used cooking oil, fertilizer, certain industrial fluids — can create expensive pollution liability if spilled. If you haul anything that could contaminate the environment, EIL coverage is strongly recommended.

Key Facts About Environmental Liability

Standard liability policies EXCLUDE pollution cleanup costs
Diesel, fuel, and chemical spills can trigger $50K–$500K+ in remediation costs
Both gradual and sudden release scenarios should be covered
Government-mandated cleanup requirements (EPA, state agencies) are time-sensitive
Some states have additional financial responsibility requirements for fuel carriers

Common Questions About Environmental Liability

Why doesn't standard liability cover fuel spills?

Nearly all commercial auto liability and general liability policies include a 'pollution exclusion' that specifically excludes costs related to the release of pollutants — and diesel fuel, gasoline, and most chemicals are classified as pollutants under the exclusion. Cleaning up a fuel spill is the responsibility of the responsible party, and without EIL coverage, that cost falls entirely on you.

How much does a fuel spill remediation actually cost?

Costs vary enormously depending on the volume spilled, the environmental sensitivity of the location, and how quickly cleanup begins. A minor highway diesel spill can cost $15,000–$50,000 in absorb-and-haul cleanup. A spill that reaches a waterway or contaminates soil can easily reach $200,000–$500,000. Major chemical spills cost millions. These costs are why EIL insurance exists.
