Bulk Plant cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1920. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a bulk petroleum storage and transfer facility since at least the 1920s, when Associated-Oil Company first constructed the terminal. Now owned and operated by Shore Terminals under NuStar Energy LP, the site holds a 375,000-barrel storage capacity and handles aviation fuel, unleaded gasoline, diesel, ethyl alcohol, and fuel additives. Groundwater remediation has been ongoing since at least 1984, encompassing separate-phase petroleum (SPH) recovery systems — including belt skimmers and iSOC™ technology — manual SPH removal, and extensive groundwater monitoring, with more than 850 gallons of SPH recovered from specific wells to date. Environmental and restrictive covenants have been filed and well decommissioning completed as part of the continuing cleanup program. 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.

Petroleum contamination at this bulk terminal traces to operations that began more than six decades before 1986 — the era when occurrence-based Commercial General Liability policies were the industry standard and lacked effective pollution exclusions. The documented remediation record here, running from at least 1984 through the present, spans SPH recovery systems, long-term groundwater monitoring, and environmental covenant filings, all tied to releases from pre-1986 bulk petroleum storage and distribution at this site. Historical CGL carriers whose policies covered this terminal during that operational window may remain obligated both to recover past cleanup expenditures and to fund the remediation work still underway.

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.
