Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1980. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property was originally constructed in the early 1980s as a semiconductor wafer manufacturing facility for Fairchild Camera, with two 10,000-gallon diesel underground storage tanks installed in the Service Yard in 1982 to support operations. A diesel spill from those USTs in 1986 triggered remedial action under the Voluntary Cleanup Program, and cleanup has continued since — including UST removal, contaminated soil excavation, free-product recovery, groundwater pump-and-treat, and enhanced bioremediation through ten rounds of nitrate injections. A Monitored Natural Attenuation program with quarterly compliance monitoring has been in place, with monitoring planned through 2024. 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 diesel contamination at this site originated from underground storage tanks installed in 1982 and released during operations that predate the 1986 shift away from occurrence-based Commercial General Liability coverage. Carriers who issued CGL policies to Fairchild Camera or successor operators during the early 1980s did so under policy forms with no effective pollution exclusion in Washington. Decades of documented remediation expenditures — tank removal, soil excavation, groundwater treatment, bioremediation, and long-term monitoring — represent costs those historical carriers may be obligated both to reimburse and to fund as cleanup continues.

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.
