Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property operates as a Shell-branded retail gasoline and diesel fuel dispensing facility with a car wash, equipped with three 10,000-gallon gasoline USTs and one 10,000-gallon diesel UST. A Phase II subsurface investigation in August 1993 identified petroleum contamination, and free product was removed in 1995. The site was enrolled in the Voluntary Cleanup Program from 2009 through 2019, with 12 monitoring wells established and multi-year groundwater monitoring and sampling continuing as part of the ongoing cleanup effort. 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 contamination at this facility was already present when first investigated in 1993, confirming that the releases originated from fueling operations conducted well before 1986 — when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. Over a decade of Voluntary Cleanup Program enrollment, free product recovery, and sustained groundwater monitoring represent documented remediation expenditures tied directly to those pre-1986 operations. Historical carriers who issued CGL policies during the facility's early operational years may be obligated both to recover costs already incurred and to fund the cleanup work that remains.

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.
