Auto Body cleanup site — Restorical Research
Silvestri
Kent, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a auto body / repair shop going back to 1948. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property was developed in 1948 and has hosted various businesses since the 1950s, including an ice cream distribution operation that used the site for vehicle maintenance, painting, and repair of its fleet trucks, with a portion of the building periodically rented to mechanics for automobile maintenance. Two underground storage tanks — installed in the 1960s and 1973 for gasoline and diesel storage — were removed in June 2000, followed by multiple phases of soil excavation in 2000 and 2001 that disposed of approximately 739 tons of petroleum-impacted soil. The site was enrolled in the Voluntary Cleanup Program from August 2000 through May 2007, 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 stems from underground storage tanks installed and operated from the 1960s through at least 1981 — decades during which occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation costs to date, including tank removal, multi-phase soil excavation, and groundwater monitoring, were incurred to address releases tied directly to those pre-1986 fueling and vehicle-maintenance operations. Historical carriers who provided CGL coverage during that operational window may be obligated to reimburse past cleanup expenditures and to fund the remediation work that remains 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.
