Gas Station cleanup site — Restorical Research
Oak Harbor Marina
Oak Harbor, Island County
Restorical Research
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.

The Oak Harbor Marina operated as a marine fueling station on Island County's waterfront, dispensing unleaded gasoline and diesel to marina customers from underground storage tanks connected to floating-dock dispensers. Contamination from historic overfilling of the UST system led to petroleum-affected soils and groundwater at the site. Cleanup activities during 1996–1997 included permanent in-place closure of two 10,000-gallon USTs, pumping and offsite disposal of residual fuel, soil excavation, post-excavation sampling, and installation of a new monitoring well as part of an independent remedial action. Cleanup work is ongoing under the Standard Cleanup program. 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.

The marina's fuel-dispensing operations were already established by 1973 — the facility appears on a USGS topographic map from that year — meaning CGL policies issued to the operator during that pre-1986 window would have been occurrence-based and carried no effective pollution exclusion under Washington law. The contamination here arose from historic overfilling of the UST system over the course of those long-running fueling operations, exactly the kind of gradual, operational release those policies were written to cover. The documented remediation costs — tank closures, fuel disposal, soil excavation, groundwater investigation, and monitoring-well installation — represent expenditures the historical carriers 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.
