Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

The Alaskan Copper Works Factory in Seattle operated as an industrial facility well before 1986, with documented uses including pipe storage, welding gas handling, and manufacturing under overhead cranes in a building supported on driven timber piles. An investigation was conducted after possible hydrocarbon contamination was suspected, involving an exploratory boring whose cuttings were drummed for disposal and the boring decommissioned with bentonite and concrete. Chemical testing from that investigation found no evidence of hydrocarbons, though the site remains enrolled in Ecology's Standard Cleanup program with the review 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.

This industrial facility was in active operation well before 1986, the period when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion in Washington. While the initial investigation did not confirm hydrocarbons, the contamination question has not been fully resolved and further investigation or remediation work may still lie ahead. Pre-1986 CGL policies issued to operators of this facility during that era could provide a basis to fund cleanup costs the property owner faces as the Standard Cleanup process moves forward.

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.
