Public Works cleanup site — Restorical Research

Restorical Research
Preliminary Site-Specific Analysis

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

This property is Port of Seattle Terminal 5, a marine terminal facility at 26th Avenue SW and West Marginal Way SW in Seattle. The site has carried confirmed contamination listings on Ecology's database since 1988, with multiple contaminant classes detected in groundwater and sediment — including PCBs, halogenated organics, metals priority pollutants, petroleum products, phenolic compounds, organotins, and pesticides. A Site Hazard Assessment was initiated but not completed; the site is classified under Ecology's standard cleanup program with cleanup underway. 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 presence of PCBs at this terminal — banned nationwide in 1979 under the Toxic Substances Control Act — establishes that contamination originated no later than the late 1970s, well within the era when occurrence-based CGL policies carried no effective pollution exclusion. The breadth of confirmed contaminants across both groundwater and sediment reflects decades of industrial port operations generating environmental liability that predates 1986. Historical carriers who insured terminal operations during that window may be obligated to cover both the investigation and remediation costs incurred to date and the cleanup expenditures that lie 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.
