Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1966. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as a gasoline service station with underground fuel tanks, dispensers, and a service garage — confirmed in aerial photography as early as 1966. The primary contamination consists of leaded gasoline, diesel, and heavy oil released from underground tanks, fuel dispensers, and a service garage dump area. WSDOT performed an independent cleanup of the former station (referred to as the "Bear Property"), which included excavation of approximately 500 cubic yards of petroleum-contaminated soil, removal of a 250-gallon heating oil tank, underground fuel piping, a septic tank, and a dry well, with the contaminated soil transported off-site for bioremediation beginning in 2005. 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 petroleum contamination at this property originated from gasoline station operations that were in place by at least 1966 — two full decades before occurrence-based Commercial General Liability policies stopped reliably covering pollution claims. The use of leaded gasoline, phased out by the mid-1980s, further anchors the contamination to the pre-1986 policy era. Documented remediation expenditures — large-scale soil excavation, tank and infrastructure removal, off-site bioremediation — represent costs that historical carriers who issued CGL policies during that operational window may be obligated to reimburse, with potential ongoing liability if further cleanup action is required.

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.
