Gas Station cleanup site — Restorical Research
Totem Equipment Seattle

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1944. 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 gasoline service station from as early as 1944, with a Signal Oil Company fueling station documented at the site from 1960, before transitioning to Totem Equipment. At least five underground storage tanks — ranging from 500 to 15,000 gallons and storing gasoline, diesel, and heating oil — were present on site. Cleanup under the Standard Cleanup program has included excavation and removal of all five USTs and contaminated soil in 2007, pumping of 87,000 gallons of groundwater and chemical injections in 2008, installation of 16 monitoring and injection wells, and ongoing groundwater monitoring extending from 2006 through 2015. Remediation is ongoing. 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.

Fuel dispensing operations at this site began more than four decades before 1986, the year occurrence-based Commercial General Liability policies ceased reliably covering pollution claims in Washington. Gasoline, diesel, benzene, and oil contamination released from underground storage tanks installed and operated during that pre-1986 window is exactly the kind of long-tail environmental liability those policies were written to address. The documented remediation expenditures — tank removals, large-scale groundwater recovery, chemical injection, and years of monitoring — represent costs that historical carriers who issued CGL policies during those decades of 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.
