Preliminary Site-Specific Analysis

This property has a documented history as a property with a heating oil tank predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

A residential underground heating oil tank at this Bainbridge Island property failed in January 2011, releasing petroleum into the surrounding soil. The heating oil migrated through the foundation drain into the storm drain system and a roadside ditch along Wyatt Way NW, resulting in confirmed off-site surface water contamination. The City of Bainbridge Island cleaned the affected ditch and confirmed heating oil in the municipal stormwater system. The failed tank was decommissioned in place by filling with concrete slurry, and the site is currently awaiting further cleanup under the state's 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.

Tank lifecycle analysis indicates this underground storage tank was very likely installed before 1986, placing its original installation within the era when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion. Petroleum contamination from the tank has already migrated off-site into Bainbridge Island's stormwater infrastructure, and the property still awaits formal remediation — costs that will continue to accrue. Historical CGL policies issued during the pre-1986 period when this tank was installed and operating may be obligated to fund the investigation and cleanup expenditures the property owner now faces.

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.
