Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1930. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property was originally constructed as a service station in 1930 and operated as a gasoline station from 1932 through the mid-1940s, with pump islands documented in a 1936 aerial photograph and underground fuel storage tanks servicing the site throughout. The Gay Nineties Service Station then occupied the property from 1958 through 1968, extending the site's petroleum dispensing history across multiple decades. Environmental investigations from 2004, 2005, and 2018 confirmed diesel, heavy oil, mineral spirits, and gasoline contamination in soil and groundwater above MTCA cleanup levels; recommended remediation includes soil excavation with treatment or landfilling, installation of groundwater monitoring wells, and potential future groundwater remediation measures that have not yet commenced. 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 originates from underground fuel storage tank operations and pump islands active from 1930 through at least the late 1960s — operations conducted entirely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The site now faces an excavation, soil disposal, and multi-phase groundwater remediation program whose full costs remain unscoped and unfunded. Historical carriers who issued CGL policies to the operators of the Gay Nineties Service Station and its predecessors during that pre-1986 window may be obligated to fund the cleanup expenditures that lie 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.
