Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1946. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Spencer Industries operated this Seattle property as a manufacturing and distribution center from 1946 through 1996, assembling and repairing aircraft hydraulic components and fasteners and using trichloroethylene (TCE) as an industrial degreaser. Cleanup activities in the early 1990s included the excavation and offsite disposal of above-ground storage tanks (ASTs) and petroleum-impacted soil, followed by groundwater monitoring from 1996 through 1999 and an assessment of natural attenuation for chlorinated solvents. At an associated South Park Bridge parcel, 100 cubic yards of PCE-contaminated soil were separately excavated, managed, and prepared for offsite disposal along with associated contaminated water. Cleanup remains ongoing under the Voluntary Cleanup Program. 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.

TCE degreasing and AST operations at this site began in 1946 — four decades before the 1986 threshold at which occurrence-based Commercial General Liability policies gave way to forms with effective pollution exclusions. The contamination profile here — TCE and PCE in soil and groundwater alongside petroleum hydrocarbons from storage tanks — reflects precisely the kind of long-running industrial release those pre-1986 policies were written to cover. Historical carriers who issued CGL policies to Spencer Industries during its fifty years of active operations may be obligated both to recover documented remediation expenditures and to fund the cleanup 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.
