Gas Station cleanup site — Restorical Research
KANPAI JAPANESE RESTAURANT
Puyallup, Pierce County

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1950. 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 service station from the 1950s, when the current owners purchased the existing facility, until the early 1970s when the underground storage tanks were taken out of service. The site has been leased and operated as a Japanese restaurant since 1991. Cleanup under the Voluntary Cleanup Program has included removal of five USTs and 165 tons of contaminated soil in 2003, operation of an air sparging and soil vapor extraction system from 2015 to 2017 and again from 2020 to 2021, enhanced in-situ bioremediation with oxygen release compound injections in 2020 and 2022, and extensive groundwater monitoring spanning 2004 through 2024. Cleanup work is ongoing, with additional bioremediation injections planned. 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 contamination at this property originated from underground storage tanks that were installed and operated beginning in the 1950s — more than three decades before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion in Washington. Two decades of documented remediation expenditures — tank removal, soil excavation, vapor extraction, bioremediation, and long-term monitoring — were incurred to address releases tied directly to those pre-1986 fueling operations. Historical carriers who issued CGL policies during the station's operating years may be obligated both to recover costs already spent and to fund the cleanup work that remains.

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.
