What Triggers a Pollution Liability Claim?

THE MOST COMMON TRIGGERS ON EXCAVATION SITES

The events that actually start a claim are rarely dramatic. A hydraulic line failing over the course of a shift, a fuel tank overfilled during routine refueling, a bucket striking a forgotten underground storage tank, or excavated soil and stormwater carrying sediment into a storm drain are the everyday version of a pollution trigger, not the exception. The EPA’s Underground Storage Tank program and the Clean Water Act’s construction stormwater rules both cover categories of contamination that routinely originate from ordinary excavation and grading activity, not unusual accidents.

WHAT HAS TO HAPPEN AFTER THE RELEASE FOR A CLAIM TO EXIST

A release alone doesn’t automatically become a claim, there needs to be resulting damage or a regulatory response: a neighboring property owner affected by contamination migrating off-site, a government agency issuing a cleanup order, or a third party filing a claim for bodily injury or property damage tied to the release. In practice, most excavation-related pollution claims combine a physical trigger event with a regulatory notice, since state and federal environmental agencies typically require reporting once a contamination discovery meets certain thresholds.
