Understanding Tank Pollution Liability Insurance: Protecting Your Business and Financial Future

Underground Storage Tank (UST) owners and operators face significant financial risks due to potential environmental contamination. Ensuring compliance with financial responsibility requirements is critical for continued business operation and legal protection. One of the most common mechanisms for meeting these requirements is pollution liability insurance. However, unlike standard home, business, or auto insurance, which is typically written on an occurrence basis, most UST insurance policies are written as claims-made policies. This article explains the key aspects of these policies, the importance of maintaining coverage continuity, and the steps you should take to protect yourself when selling your facility.

Occurrence vs. Claims-Made Policies

Understanding the distinction between occurrence and claims-made policies is crucial when selecting pollution liability insurance.

Occurrence Policies: These policies cover claims arising from incidents that occur during the policy period, regardless of when the claim is reported. For example, if a covered peril or event occurs in 2010 but is discovered and reported in 2024, an occurrence policy from 2010 would still provide coverage.
Claims-Made Policies: These policies only cover claims if both the incident or event and the claim report occurs while the policy is in force. Once the policy expires, no claims can be filed with the insurance company unless an extended reporting period is purchased.

Most UST pollution liability insurance is written on a claims-made basis, meaning operators must be vigilant in maintaining continuous coverage to avoid gaps that could leave them financially exposed.

The Importance of the Retroactive Date

A retroactive date establishes the earliest point in time for which coverage applies under a claims-made policy. This is critical because a claim can be covered only if the incident occurred on or after the retroactive date and was reported during the policy period.

Arizona financial responsibility regulations require the retroactive date must be one of the following:

The date of installation of the tank system
The date of the most recent baseline assessment or comparable site characterization
The earliest retroactive coverage date of the previous insurance policy

Switching insurance providers without preserving your retroactive date can result in losing coverage for past incidents. If you change insurers, ensure that the new policy honors your existing retroactive date or create a new older retroactive date. This is a required practice in Arizona to protect policyholders from unintentional coverage gaps.

The Role of Extended Reporting Periods

An Extended Reporting Period (ERP) provides additional time to report claims for incidents that occurred during the policy period but were discovered after the policy ended.

ERPs are typically sold in one-year increments.
They are particularly important when selling a facility, as contamination from previous operations may not be discovered until after the sale.

For example, if you sell your UST-equipped property, the new owner may discover contamination soon after taking over. If your policy was terminated at the time of the sale, you may be held liable with no insurance coverage. Purchasing an ERP allows you to file claims for events that occurred while you owned the property.

Steps to Protect Yourself When Selling Your Facility

To safeguard your financial interests when selling a UST-equipped facility, consider these steps:

Conduct a Baseline Environmental Assessment: Many lenders require a site check or a baseline assessment before funding a petroleum storage tank facility purchase. If contamination is found before closing, you can file a claim under your existing policy.
Purchase an Extended Reporting Period: If no contamination is found but is later discovered by the buyer, an ERP will allow you to file a claim.
Ensure the Buyer Has Proof of Financial Responsibility: Require the new owner to have an active pollution liability policy at the time of sale. Verify that they have met regulatory requirements.
File Change of Ownership Notices: Submit the necessary paperwork with state agencies to formally transfer ownership and liability. You do not want the state to think you still own the tanks and could potentially notify you as the known responsible party for a release occurring after you have sold the facility.

Where to Find Pollution Liability Insurance Providers

The U.S. Environmental Protection Agency (EPA) maintains a list of insurance providers that offer pollution liability coverage for UST owners and operators. While the EPA does not endorse specific providers, their list is a valuable resource for finding insurers who specialize in this type of coverage. You can access the list at https://www.epa.gov/ust/list-insurance-providers-ust-financial-responsibility-requirements.
