Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1971. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a Washington State Department of Transportation maintenance facility since at least 1971, with underground storage tanks used for dispensing gasoline and diesel fuel and collecting waste oil. In 1989, three USTs totaling 4,800 gallons of capacity were removed, and contaminated soil was over-excavated, stockpiled, and tested for potential reuse as fill material. Cleanup work at the site 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 here — from gasoline, diesel, and waste oil storage tanks in active use well before 1986 — traces directly to the era when occurrence-based Commercial General Liability policies were still standard and carried no effective pollution exclusion. The documented remediation work, including UST removal and soil excavation, was incurred to address releases tied to those pre-1986 operations. Historical carriers who issued CGL policies to the facility or its operators during that window may remain obligated to recover those past cleanup costs and to fund continuing remediation.

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.
