Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1971. 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 gasoline station and car washing facility since its construction in 1971, with three underground storage tanks installed that year and a fourth 15,000-gallon tank added in 1979. A 1993 Consent Decree initiated a phased cleanup that has included removal of 34 tons of contaminated soil, operation of an air sparging and soil vapor extraction system from 1995 to 1996, installation of additional monitoring wells in 2007, and an enhanced fluid recovery test in 2008 that removed 100 pounds of petroleum vapors. Remedial investigation work continued through 2022–2023, with a Feasibility Study still ahead and Ecology's reimbursable costs capped at $250,000. 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 site is attributed to historical service station operations that began in 1971 — fifteen years before occurrence-based CGL policies gave way to claims-made forms with absolute pollution exclusions. The cleanup cost trail already spans three decades and continues to grow: soil removal, vapor extraction, long-term monitoring, and a Feasibility Study yet to come. Carriers who issued occurrence-based policies to the operators during the 1971–1986 window may be obligated both to reimburse past remediation expenditures and to fund the cleanup work that remains.

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.
