Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1962. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a gas station since 1962, with seven underground storage tanks holding diesel, multiple grades of unleaded gasoline, and waste oil. Cleanup activities have included removal of all seven USTs and partial excavation of contaminated soil in 1991, remediation of a 60-gallon fuel spill around 2000, and a site investigation and monitoring program spanning from 1991 through at least 2014. Contaminated soil remains in place, and cleanup is ongoing. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.

Why Historical Insurance Policies May Be Accessible

Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.

Petroleum contamination at this property originated from underground storage tanks installed and operated beginning in 1962 — more than two decades before occurrence-based CGL policies gave way to claims-made forms with pollution exclusions. The documented remediation expenditures to date — tank removals, soil excavation, spill cleanup, and over twenty years of monitoring — along with the cost of addressing contaminated soil still in place, represent the kind of long-tail environmental liability that historical carriers may be obligated both to recover and to fund going forward.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
