Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1971. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a Chevron-branded gasoline service station since at least 1971, with three underground storage tanks and fuel dispensers serving retail customers. Petroleum hydrocarbon contamination was discovered beneath the dispenser islands during product line and dispenser upgrades in 1996, and the presence of total lead in soil samples points to historical use of leaded gasoline. Cleanup under the Voluntary Cleanup Program has included soil excavation during the 1996 upgrades, groundwater treatment via oxygen injection and granular activated carbon filtration, and ongoing groundwater monitoring conducted between 2000 and 2012. The station remains in active commercial operation. 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 dispensing operations at this site began at least fifteen years before 1986, when occurrence-based Commercial General Liability policies were still standard and carried no effective pollution exclusion in Washington. The contamination discovered here — petroleum hydrocarbons released from product lines and dispenser islands, with leaded-gasoline indicators confirming the pre-1986 origin — is precisely the kind of long-duration release those policies were written to cover. Documented remediation expenditures spanning excavation, groundwater treatment, and over a decade of monitoring represent costs that historical carriers who insured the station during its early operating years may be obligated both to reimburse and to fund on a going-forward basis.

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.
