Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1974. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a gasoline service station since at least 1974, when its building was constructed, with five underground storage tanks holding gasoline and diesel across two fueling islands. Leaking USTs were identified as a contamination source by 1989, and the site was enrolled in Washington's Voluntary Cleanup Program from 1999 through 2006. Remediation included the removal of at least 370 tons of contaminated soil, the decommissioning of a 5,000-gallon underground storage tank, and groundwater monitoring that continued through at least 2007. 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 documented at this property originated from underground storage tanks installed no later than the mid-1970s — more than a decade before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion. Slow leakage from those tanks into soil and groundwater is precisely the type of gradual release that pre-1986 CGL policies were written to address. The remediation expenditures recorded here — hundreds of tons of soil excavation, UST decommissioning, and years of groundwater monitoring — represent costs that historical carriers whose policies covered operations during that pre-1986 window may be obligated to recover and to fund as cleanup continues.

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.
