Public Works cleanup site — Restorical Research
Port of Seattle Terminal 46
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1981. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This terminal property, owned by the Port of Seattle and leased to Hanjin Shipping Co. for cargo operations, housed underground storage tanks installed in 1981 at a fueling station used to fuel terminal equipment. Cleanup under the Standard Cleanup program has included two UST removal events — two 5,000-gallon tanks and 200 cubic yards of contaminated soil removed in 1991, followed by an estimated 1,900-gallon tank and 70.7 tons of contaminated soil removed in 2009 — along with multi-year groundwater monitoring and additional well installations beginning in 1992. Some contaminated soil was left in place after the 2009 removal, and cleanup work 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 USTs at this terminal were installed in 1981 and dispensed leaded gasoline — a fuel phased out before 1986 — confirming that the contaminating operations fell squarely within the era of occurrence-based Commercial General Liability policies with no effective pollution exclusion. Petroleum hydrocarbons and lead have been detected in soil at the site, and decades of documented remediation costs — tank removals, soil excavation and disposal, groundwater monitoring infrastructure — represent expenditures that historical carriers who covered Port or lessee operations during the early 1980s may be obligated both to reimburse and to fund going 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.
