Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1920. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has served automotive purposes since 1920, with gasoline fueling, oil service, and repair operations documented between at least 1935 and 1969. Two underground storage tanks were discovered on-site in 1993. Investigations under the Voluntary Cleanup Program have confirmed contamination in both soil and groundwater, including TPH-d, TPH-o, BTEX, PAHs, arsenic, barium, chromium, lead, and mercury. As of 2017, petroleum-contaminated soil remained on-site and groundwater impacts continued to occur, with further groundwater characterization required by Ecology. 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.

Gasoline fueling and oil service operations at this property date to at least 1935 — more than five decades before 1986, when occurrence-based CGL policies ceased reliably covering pollution claims. The petroleum and metals contamination now documented in soil and groundwater here traces directly to those decades of pre-1986 automotive operations. With cleanup underway and additional groundwater characterization still required, the historical carriers who issued CGL policies during that operational window may be obligated both to recover past remediation expenditures and to fund the work that remains.

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.
