Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1929. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

A retail gasoline service station operated on this property from 1929 through 1936 and is identified as the suspected source of petroleum hydrocarbon contamination — TPH-G, TPH-D, and BTEX — documented at the site. Cleanup under the Voluntary Cleanup Program ran from 2015 through 2017 and included excavation of approximately 3,400 tons of contaminated soil, draining and removal of perched groundwater encountered during that excavation, and demolition of existing on-site structures to enable the remediation work. Cleanup work is ongoing. 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 property traces to gas station operations that ceased nearly half a century before 1986 — the last year occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. The 3,400 tons of excavated soil, the groundwater removal, and the structural demolition all represent documented remediation expenditures tied directly to that pre-1986 operational source. Historical carriers who issued CGL policies during the station's 1929–1936 active years may bear obligations both to recover those past costs and to fund continued cleanup 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.
