Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1977. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property operated as a gasoline service station from at least 1977, when the facility building was constructed, with underground storage tanks in place until their removal in 1987. Phase I and II site investigations have confirmed gasoline above MTCA Method A cleanup levels in soil, and gasoline, diesel, and 1,2-dibromoethane (EDB) above cleanup levels in groundwater. The property is in the process of being acquired; the buyer intends to conduct an independent remedial investigation and cleanup under the Voluntary Cleanup Program or a Pollution Liability Insurance Agency program, and no active remediation has commenced. 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 underground storage tanks at this site were installed and actively dispensing fuel before 1986, the year occurrence-based Commercial General Liability policies with no effective pollution exclusion gave way to policies that explicitly excluded contamination claims. The gradual release of gasoline, diesel, and EDB into soil and groundwater is precisely the type of long-tail pollution event those pre-1986 policies were written to cover. The investigation and remediation costs the incoming owner now faces — site characterization, cleanup design, and remediation itself — could plausibly be funded by historical carriers whose CGL policies were in effect during the operational years of those tanks.

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.
