Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1976. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property operated as a petroleum bulk plant with underground storage tanks installed as early as October 1976, including waste oil, preventalube, and aviation fuel tanks — with a gasoline UST added in January 1985. Groundwater beneath the site has been confirmed above cleanup levels for halogenated solvents, benzene, and petroleum hydrocarbons including diesel. The site is enrolled in Washington's Voluntary Cleanup Program and is currently awaiting cleanup. 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.

The underground storage tanks at this bulk plant were installed between 1976 and 1985 — a full decade of operations falling squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Groundwater contamination confirmed at the site spans multiple chemical classes, from halogenated solvents to benzene and petroleum products, pointing to releases tied directly to those pre-1986 tank operations. The investigation and remediation costs this property now faces could plausibly be funded by historical carriers whose policies were in effect when the contamination first occurred.

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.
