Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1930. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as a fuel service station from approximately 1930 through the 1970s, with three successive generations of gas station operations documented on the site and underground storage tanks installed as early as 1930, with additional installations in 1951, 1959, and between 1961 and 1967. Cleanup activities commenced in 2022 with the removal of five remaining USTs, an in-ground hydraulic hoist, and 320.9 tons of petroleum-contaminated soil. Groundwater remediation followed in Spring 2023 with injections of PetroFix micro-granular carbon, and quarterly groundwater monitoring along with additional investigations and augmented remediation injections are ongoing into 2024. 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 — gasoline, diesel, and BTEX compounds — originated from storage tanks installed and operated across multiple decades beginning in 1930, well before 1986 when occurrence-based Commercial General Liability policies were still written without effective pollution exclusions. The documented sequence of UST installations spanning 1930 through the mid-1960s, followed by releases confirmed in soil and groundwater, ties this contamination directly to the pre-1986 operational window. The remediation expenditures incurred to date — UST removals, soil excavation, groundwater injection treatment, and continuing monitoring — represent costs that historical carriers who issued CGL policies during that decades-long operational period 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.
