Gas Station cleanup site — Restorical Research
Bobs Texaco Station
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1941. 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 Texaco gasoline service station from 1941 through 1997, with underground storage tanks for gasoline and diesel installed as early as 1956. Cleanup activities have included the excavation and removal of five USTs and 510 cubic yards of petroleum-contaminated soil in 1995, followed by on-site biological treatment of stockpiled soils from June through August 1996 — after which 460 cubic yards were disposed off-site and 50 cubic yards were re-used on-site. Groundwater monitoring wells were installed in 1995, with sampling conducted in 1995, 1996, and 2011 as natural attenuation continued over 15 years. The former station is no longer in operation. 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 property originated from underground storage tanks that were installed and operated for decades before 1986 — some containing leaded gasoline, a definitive pre-1986 indicator. Occurrence-based CGL policies issued to the operators during that window carried no effective pollution exclusion under Washington law and remain enforceable today. The documented remediation expenditures — tank removal, soil excavation, biological treatment, off-site disposal, and over fifteen years of groundwater monitoring — represent costs the historical carriers may be obligated both to recover and to fund as cleanup continues.

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.
