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 1930. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property operated as a bulk fuel terminal during the 1930s, storing petroleum products in an above-ground tank measuring 100 feet in diameter with an estimated capacity of 500,000 to 1,000,000 gallons; the tank was removed around 1934. Contamination linked to those historical operations was discovered decades later, prompting site investigations and monitoring from 1995 through 2008. Remediation included excavation and removal of contaminated soil in 1996 and the implementation of engineering controls for water runoff, after which Ecology issued a No Further Action determination. 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 at this property traces to bulk fuel storage operations conducted in the 1930s — more than fifty years before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion. The scale of the former operation, a tank holding up to one million gallons of fuel, and the documented remediation expenditures — multi-year investigations, soil excavation, engineering controls, and over a decade of monitoring — represent cleanup costs tied directly to that pre-1986 operational period. Historical carriers who issued CGL policies to the operators or property holders during that window may still be obligated to recover those 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

  • Historical insurance policies (pre-1986)

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.
