Gas Station cleanup site — Restorical Research
Pasciuto Property
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1936. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as a gasoline service station and automotive repair facility from at least 1936 through approximately 1963, with fuel dispensing concentrated on the southeastern portion of the property and vehicle repair occupying the central and western portions. Cleanup work under the Voluntary Cleanup Program has included the removal of two underground storage tanks, excavation of more than 240 tons of contaminated soil, recovery of 1,241 gallons of light non-aqueous phase liquid (LNAPL) and 21,620 gallons of petroleum-contaminated groundwater via enhanced fluid recovery, and pneumatic skimmer installation. Planned work includes soil segregation and disposal, vapor barrier installation, and construction and long-term monitoring of a multi-phase extraction (MPE) system, with at least one year of continued monitoring anticipated. 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 petroleum contamination at this property — LNAPL, benzene, and petroleum hydrocarbons in soil and groundwater — originates from underground storage tank operations and automotive repair activities that began in the 1930s, more than four decades before 1986. Occurrence-based Commercial General Liability policies issued to operators during that pre-1986 window carried no effective pollution exclusion under Washington law and remain enforceable today. The documented remediation expenditures already incurred — UST removals, soil excavation, LNAPL recovery, groundwater extraction — and the substantial cleanup work still underway represent costs that historical carriers may be obligated both to reimburse and to fund going forward.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

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 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
