Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1954. 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 an automotive service facility since 1934, with gasoline dispensing added in 1954 when four dispenser pumps on two islands and underground storage tanks were installed east of the building. Cleanup to date has included prior UST removals and the excavation and disposal of 523.43 tons of petroleum-impacted soil over four days in September 2018. Quarterly groundwater monitoring and natural attenuation are ongoing, and additional site-wide soil excavation is planned in connection with future construction on the property. 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.

Gasoline storage and dispensing at this site began in 1954 — more than three decades before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion. The documented presence of a leaded gasoline UST confirms that the contamination source was active during the very era those policies were written, and the attribution of impacted soil and groundwater to historical gasoline station operations and long-removed USTs makes clear that no recent accident accounts for the liability. The remediation record here — UST removals, nearly 525 tons of excavated soil, ongoing groundwater monitoring, and a further construction-phase excavation still to come — reflects expenditures that historical carriers 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.
