Gas Station cleanup site — Restorical Research
Phom Property

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 retail gasoline service station from 1936 to 1967, with underground storage tanks and fuel dispensers that have since been removed. Gasoline-range hydrocarbons and BTEX compounds attributed to that former station have been identified in an estimated 285 to 307 cubic yards of contaminated soil across the site. Current remediation includes an active soil vapor extraction system recovering petroleum hydrocarbons from the subsurface, with plans on record for deep soil excavation reaching up to 30 feet and removal of a heating oil tank. Cleanup is ongoing under the Standard Cleanup program. 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 gasoline station that contaminated this property operated continuously from 1936 through 1967 — a full three decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. Leaking underground storage tanks from that era deposited the petroleum contamination now requiring active abatement: a soil vapor extraction system is already in operation, and hundreds of cubic yards of affected soil are earmarked for excavation. Historical carriers that issued CGL policies to the station's operators during any portion of those thirty-one years of operation may be obligated to fund both the remediation costs already incurred and the significant excavation work that lies ahead.

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.
