Bulk Plant cleanup site — Restorical Research
Time Oil Bulk Terminal
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1941. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This Seattle property operated as a petroleum bulk storage and distribution terminal from 1941 through October 2001, with large aboveground storage tanks supplying fuel distributed onward by transport ship, railroad tank car, and truck. Cleanup activities have been underway since 1991 and have included removal of underground and aboveground storage tanks, soil excavation targeting petroleum hydrocarbon and pentachlorophenol contamination, a full-scale F027 hazardous waste soil removal, a dual-phase extraction pilot test, installation of a stormwater pretreatment system, and in-situ chemical oxidation, with monitoring continuing to the present. Remediation is ongoing under the Voluntary 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.

Bulk petroleum storage and distribution operations at this property began in 1941 — more than four decades before 1986 — and a leaded-gasoline underground storage tank confirmed to predate current pollution exclusions was not removed until 1991. Occurrence-based CGL policies issued to the terminal operators during that long pre-1986 window carried no effective pollution exclusion and remain enforceable today. The documented remediation trail — UST and AST removals, pentachlorophenol and F027 hazardous waste excavation, extraction systems, and years of ongoing monitoring — represents expenditures that historical carriers whose policies were in force during those operational decades may be obligated both to recover 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.
