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 1924. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has been the site of petroleum bulk storage and distribution operations dating to at least 1924, including multiple aboveground storage tanks and an underground storage tank associated with a petroleum company storage facility. Cleanup activities included UST removal (circa 1997), removal of several ASTs, and excavation of approximately 57 tons of TPH-D contaminated soil in January 2008. A Cleanup Action Plan prepared in 2010 proposed in-situ chemical oxidation, long-term groundwater monitoring, and institutional controls, but those planned remediation activities were never implemented, and the site withdrew from the Voluntary Cleanup Program in 2015. 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 operations at this property span back to at least 1924, with documented investigation of pre-1996 fuels and leaded gasoline confirming that bulk fuel storage and distribution were active here long before 1986 — the year effective pollution exclusions entered occurrence-based CGL policies. The contamination left behind — petroleum hydrocarbons spread through soil and groundwater from historic tank spills — is precisely the type of slow, long-running release those pre-1986 policies were written to address. With a proposed cleanup plan never executed and remediation obligations unresolved, historical carriers whose policies were in force during that decades-long operational window may be obligated both to recover costs already incurred and to fund the work still 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.
