Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1973. 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 retail gasoline service station since approximately 1973, branded at various times as a Texaco, Union 76, and Shell station with underground storage tanks and fuel dispenser islands. In 1993, petroleum contamination associated with the dispenser islands was discovered and reported, prompting the removal of two underground storage tanks and excavation of 210 cubic yards of impacted soil under the Voluntary Cleanup Program. A multi-year groundwater monitoring program followed from 1993 through 2011, including the installation and decommissioning of multiple monitoring wells and disposal of investigation-derived waste. The property remains in active commercial use as a retail gasoline station and convenience mart. 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 originated from fuel-dispensing infrastructure installed and operated beginning in 1973 — more than a decade before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. The release from the dispenser islands was a slow, operational-period event, not a sudden accident, which is precisely the type of occurrence these pre-1986 policies were written to cover. Nearly two decades of documented remediation expenditures — tank removals, soil excavation, well installation, and long-term groundwater monitoring — represent costs that historical carriers who issued CGL policies during that operational window 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.
