Preliminary Site-Specific Analysis

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

Seven underground storage tanks were removed from this Richland property between 1992 and 1996, with sampling confirming soil and groundwater contamination from hazardous substances at the site. Remedial actions have been conducted, and additional cleanup work remains underway under Ecology's 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.

The seven USTs at this property were in the ground long before their 1992–1996 removal, placing the operational window for these tanks squarely in the pre-1986 era when occurrence-based CGL policies carried no effective pollution exclusion in Washington. The contamination in soil and groundwater that triggered tank removal and ongoing remediation is the kind of gradual release those policies were designed to cover. Documented cleanup expenditures — tank removals, site investigation, and continuing remedial actions — represent costs that historical carriers on the risk during that operational window may be obligated to fund.

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.
