Gas Station cleanup site — Restorical Research

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, now known as Heritage Park, contains a documented Former UST Area associated with historical fuel-dispensing operations that introduced gasoline, diesel, BTEX compounds, and lead into both soil and groundwater at concentrations exceeding MTCA Method A cleanup levels. Remediation included Vactor excavation at the former UST location, and the site was enrolled in the Voluntary Cleanup Program as part of the Water Street Redevelopment Area Phase II project. Groundwater monitoring ran for at least 14 years — from 2002 through 2016 — before the site received 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 co-occurrence of leaded gasoline contamination with petroleum hydrocarbons at this property is a reliable indicator that the underground storage tanks were in operation before 1986, when leaded fuel was still dispensed and federal UST regulations had not yet taken effect. CGL policies issued on an occurrence basis during that pre-1986 window contained no effective pollution exclusion in Washington and remain enforceable today. The documented remediation costs — excavation, Voluntary Cleanup Program enrollment, and more than a decade of groundwater monitoring — represent expenditures that historical carriers who covered those fuel-dispensing operations may be obligated to recover.

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.
