Gas Station cleanup site — Restorical Research

Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1935. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The western parcel of this property hosted a gas station pump island from at least 1935 through 1937, alongside an automotive repair shop and a heating oil underground storage tank — all historical uses that contributed to petroleum contamination concentrated around the former pump island. Remediation has included the removal of a UST and nearly 14,000 tons of petroleum- and cPAH-impacted soil, site demolition, monitoring well decommissioning, and the installation of a vapor barrier. The site remains in active compliance with ongoing groundwater monitoring. 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 originated from gas station and automotive operations conducted more than five decades before 1986 — the year occurrence-based Commercial General Liability policies ceased to reliably cover pollution claims in Washington. Carriers who issued CGL policies to the operators of this pump island and repair shop during that pre-1986 window wrote those policies before effective pollution exclusions existed. The documented remediation expenditures here — UST removal, excavation of nearly 14,000 tons of impacted soil, vapor barrier installation, and continuing groundwater monitoring — represent costs that historical carriers may still be obligated to fund.

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.
