Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1955. 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 service station from approximately 1955, first under Conoco through 1977 and then under Palouse Producers for fueling, storage, and bulk fuel distribution until approximately 1985. Historical cleanup activities included excavation of roughly 850 cubic yards of impacted soil, removal of aboveground and underground storage tanks, recovery of 4,000 gallons of product from groundwater, and installation of interceptor trenches and containment infrastructure. The selected remedy calls for excavation of an additional 2,300 cubic yards of contaminated soil, monitored natural attenuation of groundwater over an estimated fifteen-year horizon, new monitoring wells, and institutional controls with periodic reviews. 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.

Petroleum contamination at this site originated from service-station operations that began in 1955 — more than three decades before occurrence-based Commercial General Liability policies gave way to claims-made forms with pollution exclusions. The documented remediation costs already incurred — tank removals, large-scale soil excavation, groundwater recovery — along with the ongoing monitoring program and additional excavation still ahead, represent expenditures directly tied to releases during that pre-1986 operational window. Historical carriers who issued CGL policies to Conoco or Palouse Producers during those years may still be obligated to fund both past and continuing cleanup costs.

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.
