Industrial & Manufacturing cleanup site — Restorical Research
Foss Maritime Co
660 W Ewing St, Seattle, King County
Restorical Research
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 — and recover costs already spent.

This industrial maritime facility operated underground storage tanks that were closed in place in 1970 and 1973, with an additional gasoline UST removed in 1990 following a release reported in 1988–1989. A 1995 Independent Remedial Action Report prepared by Hart Crowser documented extensive petroleum contamination, and approximately 8,400 cubic yards of petroleum-contaminated soil have been remediated. Seven contaminants — including benzene, polycyclic aromatic hydrocarbons, and multiple petroleum fractions — have been confirmed above cleanup levels in groundwater, and cleanup work under the Standard Cleanup program 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.

The petroleum contamination at this property traces directly to underground storage tanks that were installed and operated decades before 1986, when occurrence-based Commercial General Liability policies routinely covered pollution claims without exclusion. The scale of remediation already undertaken — 8,400 cubic yards of contaminated soil removed and seven contaminants exceeding cleanup levels in groundwater — reflects substantial expenditures tied to those pre-1986 operations. With cleanup still in progress, historical carriers whose CGL policies were in force during the tanks' operational life may be obligated both to reimburse past costs and to fund the remaining 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.
