Gas Station cleanup site — Restorical Research
Olympia City of Heritage Park

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1946. 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 gasoline fueling station and machine shop with underground storage tanks installed as early as 1946, 1949, and 1951. Cleanup efforts spanning from at least 1994 to 2016 have included the excavation and removal of multiple USTs totaling 4,200 gallons, demolition of site structures, operation of an air sparging and soil vapor extraction system that recovered over 400 pounds of hydrocarbons, and extensive drilling and installation of monitoring wells for ongoing assessment. Petroleum hydrocarbons, BTEX compounds, and lead contamination have been confirmed in both soil and groundwater, with the presence of lead strongly indicating the historical use of leaded gasoline. 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.

Fuel dispensing operations at this site began in 1946 — four decades before occurrence-based Commercial General Liability policies stopped reliably covering pollution claims in 1986. The contamination documented here, including petroleum hydrocarbons, benzene, and lead from leaded gasoline, is tied directly to tank installations and fueling operations that predated that cutoff by decades. More than twenty years of documented remediation expenditures — tank removals, structure demolition, vapor extraction, and long-term monitoring — represent costs that historical carriers may be obligated both to recover and to fund as cleanup continues.

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.
