Preliminary Site-Specific Analysis

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

This property housed multiple regulated underground storage tanks containing gasoline and diesel fuel to support operations at the Overlake Golf & Country Club. Cleanup activities spanned from 1993 to 2012, beginning with the removal of a gasoline UST in 1993 and continuing with the removal of two additional USTs — gasoline and diesel — and the overexcavation and off-site disposal of approximately 550 tons of petroleum-contaminated soil in 2007. Soil and groundwater sampling confirmed that Method A cleanup levels were achieved. 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 petroleum contamination at this site originated from underground storage tanks described as old at the time of their removal in the 1990s, placing their installation and operation well before 1986. Occurrence-based CGL policies in effect during those earlier decades of tank operation carried no effective pollution exclusion under Washington law. The documented remediation costs — multiple UST removals, large-scale soil excavation and disposal, and years of confirmatory sampling — represent expenditures that historical carriers may be obligated to cover.

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.
