Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1962. 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 Chevron gasoline service station from 1962 to 1987, with underground storage tanks and pump islands serving retail fuel customers. Following UST removal in early 1987 and subsequent investigations, cleanup activities included the excavation of approximately 2,600 to 3,160 cubic yards of petroleum-impacted soil in 1991, multi-year groundwater monitoring from 1990 through 2009, abandonment of five monitoring wells, and management of investigation-derived waste. The site was also enrolled in the Voluntary Cleanup Program, and cleanup work remains 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.

Petroleum contamination at this property originated from underground storage tanks installed and operated continuously from 1962 — more than two decades before occurrence-based CGL policies ceased reliably covering pollution claims in 1986. The documented remediation expenditures here — large-scale soil excavation, nearly two decades of groundwater monitoring, well decommissioning — were incurred to address releases tied directly to those pre-1986 fueling operations. Historical carriers who issued CGL policies to the operator during that 1962–1986 window may be obligated both to recover past cleanup costs and to fund remediation still ahead.

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.
