Gas Station cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1940. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This waterfront property has been in commercial and industrial use since the early 1900s, with boat moorage operations dating to the 1940s and a marina fueling operation served by seven underground storage tanks. UST removal in 1991 revealed petroleum and lead contamination in subsurface soil and groundwater, triggering a seven-year cleanup program from 1992 through 1999 that included free-product recovery, groundwater pump-and-treat, and subsurface injections. Institutional controls remain in place, and future remediation at the adjacent Portage Bay Park — including an upland soil remedy, groundwater remedy, and long-term monitoring — carries an estimated cost of $1.05 million to $1.65 million. 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 and lead contamination at this site originated from marine-fueling USTs that were installed and operated decades before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The use of leaded gasoline at the fueling dock is itself a marker of pre-1986 operations, since leaded fuel was largely phased out by that time. Seven years of completed remediation and over a million dollars in projected future cleanup costs represent expenditures that historical CGL carriers who covered the marina's fueling operations 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.
