Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1900. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

Terminal 5 at the Port of Seattle has operated as an industrial waterfront facility since the early 1900s, when the area was filled to establish space for industrial uses — including petroleum bulk storage and distribution. Site cleanup activities have included excavation and disposal of petroleum-contaminated soil and debris, followed by installation of groundwater monitoring wells and multi-year soil-boring investigations. The contamination — heavy petroleum products and oil-like material in subsurface soil — was encountered during ongoing site-wide modernization construction, indicating a legacy of petroleum handling that long predates the current redevelopment. 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-range and lube oil-range petroleum hydrocarbons documented at Terminal 5 originated from bulk storage and distribution operations that were underway at this site for decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion. The documented remediation costs — contaminated soil excavation, debris disposal, monitoring well installation, and multi-year groundwater sampling — represent expenditures tied directly to those historical operations. With cleanup ongoing and modernization continuing to expose subsurface contamination, historical carriers who issued CGL policies during the terminal's pre-1986 operational window may be obligated both to recover those costs and to fund the work that remains.

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.
