Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1976. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property on Aurora Avenue North operated as a fuel-dispensing facility with pump islands and three underground storage tanks alongside the Brown Bear Car Wash. In approximately 1976, an accidental surface spill of roughly 900 gallons of unleaded gasoline occurred at the site, leaving residual petroleum hydrocarbon contamination in soil and groundwater. Independent remedial actions and site closure activities were conducted under Ecology's Voluntary Cleanup Program, ultimately resulting in 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 gasoline spill that triggered contamination at this property occurred in 1976 — a full decade before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. CGL policies in force during the mid-1970s had no effective pollution exclusion under Washington law, and the documented remediation costs incurred to close out the petroleum contamination are the type of expenditure those historical policies were written to cover. Carriers who insured the facility's fuel-dispensing operations at the time of the spill may still be obligated to reimburse 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.

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.
