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.

This property operated as a gasoline service station with at least three underground storage tanks — a 2,000-gallon tank, a 3,000-gallon tank, and a 500-gallon reserve tank plumbed directly into the dispenser pipelines as a backup fuel supply. A petroleum release was reported to Ecology in 1991, and full UST removal followed in July–August 2004. Remediation included excavation of 30 tons of petroleum-impacted soil for thermal treatment and recycling, and the pumping and disposal of 60 gallons of impacted groundwater; 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 site originated from underground storage tanks that were in active operation before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The documented remediation here — tank removals, soil excavation, and impacted-water disposal — represents costs directly traceable to that pre-1986 operational window. Historical carriers who issued CGL policies while the tanks were dispensing fuel may be obligated to recover expenditures already incurred and to fund any continuing cleanup obligations 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.
