Preliminary Site-Specific Analysis

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

This property operated as a gas station with underground storage tanks that were identified as leaking by early 1989, triggering a decade of soil and groundwater remediation under Washington's Voluntary Cleanup Program that continued through 1999. Confirmed contaminants in groundwater included benzene, non-halogenated solvents, and petroleum-gasoline — consistent with long-term releases from aging UST systems. The site is listed in Ecology's Leaking Underground Storage Tank database, and a No Further Action determination was issued in February 2005. 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.

Underground storage tanks discovered leaking by 1989 were, under standard industry lifecycle assumptions, very likely installed during the 1960s or 1970s — well within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The decade-long remediation campaign at this property — soil and groundwater cleanup from 1989 through 1999 — generated documented expenditures tied directly to petroleum releases that originated during that pre-1986 operational window. Historical carriers who issued CGL policies when those tanks were installed and operating 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.
