Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1947. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.

The Edmonds School District No. 15 has operated a bus maintenance and fueling facility at this property since 1955, with the maintenance building itself constructed as early as 1947. The facility historically stored and dispensed large volumes of fuel through underground storage tanks totaling 49,000 gallons of capacity, installed across multiple decades of operation, and conducted vehicle repair, lubrication, steam cleaning, and waste oil management on-site. Cleanup activities under the Voluntary Cleanup Program have been underway since 1991, including removal of multiple USTs, excavation of 86 cubic yards of contaminated soil, free product recovery from groundwater using bailers and absorbent socks, long-term groundwater monitoring, and pavement installed as an engineering control over affected soils. The site has since received 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.

Fuel releases at this property are traced to underground storage tanks installed as far back as the early 1960s and a continuous fleet-maintenance operation running since at least 1955 — decades before 1986, when occurrence-based Commercial General Liability policies were still written without an effective pollution exclusion. The school district's CGL carriers from that pre-1986 operational window may remain obligated under those policies today. The documented cleanup costs — multiple UST removals, soil excavation, groundwater free-product recovery, and sustained long-term monitoring — represent expenditures directly tied to releases that occurred during the policy period.

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.

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.
