Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1942. 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 fuel distribution facility with 14 underground storage tanks across three tank areas constructed between 1942 and 1973. In November 1981, overfilling of the USTs resulted in a 529-gallon gasoline spill, and environmental investigations began in June 1988. The tanks were removed between 1995 and 1997. Petroleum contamination has been confirmed in groundwater, and surface water pathways connect the site to an urban wetland adjacent to Interstate 5 via the city stormwater system. Cleanup is ongoing under a 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.

Fuel storage and dispensing operations at this Chehalis facility date to 1942, more than four decades before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. The 529-gallon gasoline spill in 1981 and the petroleum contamination now confirmed in groundwater trace to infrastructure installed and operated squarely within that pre-1986 coverage window. Remediation costs already incurred — investigation, tank removal, and ongoing cleanup — as well as future expenditures to address groundwater and surface water impacts may fall within the obligations of historical carriers whose CGL policies were in force during those decades of fuel operations.

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.
