Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1970. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property operated as a corporate Texaco gasoline station with underground storage tanks likely installed around 1970, consistent with Texaco's national station buildout of the 1950s through 1970s. A 1995 UST Site Assessment and Interim Remedial Action report documented that the tanks had degraded and were leaking petroleum products — benzene, gasoline, and non-halogenated solvents — into groundwater. Remediation was conducted under the Voluntary Cleanup Program, and the site has achieved No Further Action status, with all three groundwater contaminants remediated to below cleanup levels. 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 underground storage tanks at this Texaco station were installed and operating decades before 1986, during the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Petroleum contamination from those tanks — benzene, gasoline, and related solvents confirmed in groundwater — required remedial action that generated documented cleanup expenditures. Historical CGL carriers who covered this station during the pre-1986 operational window may still be obligated to reimburse those remediation 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.
