Preliminary Site-Specific Analysis

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

This property operates as a Phillips 66 and Circle K fueling facility with underground storage tanks and fuel dispensers. Gasoline-range hydrocarbon contamination, including liquid phase hydrocarbons profiled as unleaded gasoline, has been subject to remediation under the Voluntary Cleanup Program since at least 1995. Cleanup activities have included ongoing product recovery and groundwater purging, with over 124 gallons of liquid phase hydrocarbons and 110 gallons of purge water removed to date. The presence of Total Lead in groundwater samples confirms historical releases of leaded gasoline, placing the contamination origin well before 1986. 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.

Lead contamination in the groundwater at this site is a chemical fingerprint of leaded gasoline — a product phased out of commercial sale before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion in Washington. The decades-long remediation effort here — product recovery, groundwater purging, monitoring, and cleanup planning — represents a substantial and still-growing cost trail tied directly to releases that began during that pre-1986 policy window. Historical carriers who covered the facility's operators during the leaded-gasoline era may be obligated both to reimburse past remediation expenditures and to fund the cleanup work that remains ahead.

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.
