Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1920. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This Seattle property has hosted automotive and fuel-dispensing operations since at least 1920, when oil changes and repair services were first conducted on-site, with a garage selling Union 76 gasoline documented in the 1930s. A retail gasoline station with four pump islands and two 5,000-gallon underground storage tanks was formally constructed in 1959 and operated through 1970. Under the Voluntary Cleanup Program, remediation has included the excavation and disposal of 3,375 tons of contaminated soil, removal of the two USTs, and dewatering of petroleum-affected groundwater discharged to the sewer; a foundation drain, waterproofing membrane, and vapor mitigation ventilation system are planned for future installation. 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.

Contamination at this property — petroleum hydrocarbons and lead — is directly tied to fuel dispensing and auto repair operations that began more than six decades before 1986, with underground storage tanks in place by at least 1950. Occurrence-based CGL policies covering those pre-1986 operational years carried no effective pollution exclusion and remain enforceable under Washington law. The documented remediation costs — UST removal, disposal of over 3,375 tons of impacted soil, groundwater dewatering — together with the forthcoming vapor mitigation and structural protective measures represent ongoing expenditures that historical carriers may be obligated both to recover and to fund.

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.
