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 gas station in Vancouver, Clark County, with three 675-gallon underground storage tanks and a history that included radiator, battery, and tire repair services dating to at least the late 1970s. Cleanup under the Voluntary Cleanup Program has included the 1997 excavation and removal of the three USTs along with 600 cubic yards of petroleum-contaminated soil, followed by the excavation and disposal of 1,029 tons of contaminated soil from two additional areas in 2013. In-situ chemical oxidation via hydrogen peroxide injection was used to treat inaccessible soil, and quarterly groundwater monitoring began in 2014. 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.

Gasoline-range petroleum hydrocarbons from underground storage tanks installed and operated well before 1986 are the source of contamination at this site, with groundwater concentrations at multiple locations documented far above state cleanup levels. Occurrence-based CGL policies issued to the operators during that pre-1986 window carried no effective pollution exclusion under Washington law and remain enforceable today. The remediation costs already incurred — tank removals, large-scale soil excavations, chemical oxidation treatment, and years of groundwater monitoring — along with ongoing cleanup obligations represent expenditures that historical carriers may be obligated both to recover and to fund 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.
