Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1924. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property hosted petroleum operations spanning nearly four decades, beginning with a gasoline service station on the northern portion of the site from at least 1924 through approximately 1958, with an underground gasoline storage tank documented on historical Sanborn maps. The Olympic Garage and Paulsen Martin Auto Repair operated on the southern portion from at least 1941 until 1961. Two underground storage tanks containing gasoline and diesel were closed in place in 1997, and two additional USTs were removed in 2001. Remediation was conducted under the Voluntary Cleanup Program, and the site has achieved No Further Action status. 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.

Petroleum operations at this site began as early as 1924 — more than six decades before 1986, when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion. Groundwater investigations have documented plumes of benzene, petroleum hydrocarbons, and non-halogenated solvents across multiple investigation areas, all tied to decades of gasoline storage and automotive operations predating 1986. Historical carriers who issued CGL policies during that extended operational window may still be obligated to recover the remediation costs incurred to close, remove, and address contamination from those underground storage tanks.

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.
