Gas Station cleanup site — Restorical Research
Andys Diner
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

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

This property formerly operated as a diner and truck stop that dispensed gasoline through a pump island served by a 3,000-gallon underground storage tank. The property owner confirmed the tank had not been in active use for approximately 23 years before its removal in March 1993, placing the end of fuel dispensing operations around 1970. Remediation has included UST removal, aeration and backfill of 20 cubic yards of excavated soil, and a site hazard assessment conducted in 2013–2014; deeper excavation of contaminated soils was determined to be impractical due to the extent of groundwater contamination. The site has been listed on the Confirmed and Suspected Contaminated Sites List since 1993, and cleanup work 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.

The gasoline release at this property traces to underground storage tank operations that were already inactive by approximately 1970 — at least sixteen years before the 1986 threshold after which occurrence-based CGL policies began including effective pollution exclusions. Carriers who issued commercial general liability coverage to this facility during the years when fuel was actively dispensed here may still bear obligations under those pre-1986 occurrence-based policies. The documented remediation costs — UST removal, soil excavation, site investigation — and the unresolved groundwater contamination ahead represent expenditures that historical insurers 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.
