Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1926. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as a gasoline service station from 1926 through the 1960s, with underground storage tanks in active use until at least 1965. Cleanup under the Voluntary Cleanup Program included the removal of three USTs in 2007 and the excavation and off-site disposal of approximately 451 tons of petroleum-contaminated soil. An Environmental Covenant was recorded in 2012, imposing institutional controls, long-term monitoring, and periodic reviews that remain in effect. 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.

Petroleum contamination at this property traces to gasoline operations that began in 1926 — six decades before 1986, when occurrence-based CGL policies with no effective pollution exclusion were still standard. Historical carriers whose policies were in force during that pre-1986 operational window may be obligated to reimburse the documented remediation costs already incurred: soil excavation, UST disposal, and investigation work. Separately, the 2012 Environmental Covenant imposes continuing monitoring and periodic review obligations, expenditures the same historical carriers may also be required to fund — making this a site with both a past-cost recovery claim and an ongoing-coverage dimension.

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.
