Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1919. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property at 3524 Stone Way N hosted bulk fuel and coal operations beginning in 1919, with Clark Fuel Company operating a wood and coal yard and Eastern Fuel Company occupying the northern portion of the site — both active through at least 1955. A 6,800-gallon diesel underground storage tank containing 6,550 gallons of liquid was discovered during cleanup, confirming the scale of historical bulk fueling infrastructure on the property. Voluntary Cleanup Program remediation, completed in early 2023, included excavation and off-site disposal of approximately 15,857 tons of contaminated soil, removal of the diesel UST, treatment of 890,000 gallons of dewatering and stormwater discharge, installation of a vapor barrier and air management system, and execution of an environmental covenant with periodic reviews; groundwater monitoring remains scheduled through at least 2028. 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 petroleum contamination and carcinogenic PAH loading documented at this site are explicitly attributed to bulk fueling operations that began in 1919 — more than six decades before 1986, when occurrence-based Commercial General Liability policies were the prevailing standard and carried no effective pollution exclusion under Washington law. The remediation expenditures here are substantial and well-documented: nearly 16,000 tons of excavated and disposed soil, removal of a large diesel storage tank, treatment of nearly one million gallons of contaminated discharge, structural shoring, and institutional controls that bind the property in perpetuity. Historical carriers who issued CGL policies to Clark Fuel Company, Eastern Fuel Company, or their successors during that pre-1986 operational window may still bear an obligation to recover those cleanup costs.

Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.

Recovering Costs from an Older Cleanup

If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.

What We Look For

  • Evidence linking cleanup obligation to insured activity

What We Deliver

  • Historical Coverage Chart
  • Trigger Analysis & Property/Policy Nexus

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 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
