Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This Seattle property operated as a bulk fuel distribution terminal, appearing in regulatory records under three names — Puget Sound Terminals, Puget Sound Freight Lines T-7A, and Pacific Terminals — reflecting layered ownership and operational histories at the site. Soil and groundwater sampling confirmed petroleum contamination, with diesel and heavy oil concentrations consistent with historical bulk fuel storage and distribution activities; the source and timing of the release are unknown, and no active releases have been identified. The site is currently awaiting cleanup under an Independent Action, with planned next steps including evaluation of remedial alternatives and entry into the Voluntary Cleanup Program to pursue a No Further Action determination. 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 and heavy oil contamination beneath Puget Sound Terminals traces to historical bulk fuel operations at this terminal — a release so old that its source and circumstances can no longer be reconstructed. The multiple operating names attached to this property suggest successive ownership and management periods, each of which may have carried its own Commercial General Liability policy. If any of those carriers issued occurrence-based CGL policies before 1986 — when Washington's pollution exclusions were not yet reliably enforced — those policies may represent a recoverable source of funding for the soil and groundwater investigation and cleanup costs this site now faces.

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.
