Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1972. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property operated as a 7-Eleven convenience store and retail gasoline station from 1972 to 2002. Two single-wall steel underground storage tanks and a gasoline dispensing system were installed in September 1972, followed by a third UST in May 1979; all three were decommissioned in April 2002. Groundwater investigation identified non-halogenated solvents and petroleum products beneath the property, and cleanup was completed through the Voluntary Cleanup Program, with the site receiving 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.

Petroleum storage and dispensing operations at this property began in 1972 — fourteen years before occurrence-based Commercial General Liability policies were replaced by claims-made forms with effective pollution exclusions. The three underground storage tanks that operated here through 2002 were the source of groundwater contamination requiring investigation and remediation under the Voluntary Cleanup Program. Historical carriers who issued CGL policies during the 1972–1986 operational window may still be obligated to recover the cleanup costs incurred to address releases originating from those pre-1986 tank operations.

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.
