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

This property has a documented history as a bulk fuel distribution terminal going back to 1973. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup.

Laurehurst Oil Co has owned this bulk diesel distribution facility since 1973, and prior owners operated it for the same fuel-storage and distribution purposes before that date. The site functions as a fueling depot for commercial tanker trucks leased to independent fuel distributors and also dispenses diesel directly to private vehicles. A 1990 cleanup project recovered approximately 16 gallons of free product and water-fuel mix from sumps and a dry well, and excavated 458 cubic feet (25.21 tons) of petroleum-affected soil and gravel for landfill disposal. Site investigators noted that the majority of petroleum hydrocarbons found at depth were residual contamination from spills predating the 1990 incident; the property remains under Standard Cleanup with further remediation awaiting. 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.

Laurehurst Oil Co's ownership since 1973 — combined with prior owners' use of the same bulk diesel depot before that — means occurrence-based CGL policies covering operations at this property span more than a decade before 1986. The residual hydrocarbons investigators found at depth are explicitly tied to historical tanker-fleet fueling operations of that earlier era, not the 1990 incident in isolation, which means the triggering releases trace directly to the pre-1986 policy window. Historical carriers who issued CGL coverage to Laurelhurst Oil Co or its predecessors during those years may be obligated to fund the cleanup costs this facility 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.
