Gas Station cleanup site — Restorical Research
La Rosita Bakery
Sunnyside, Yakima County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1959. 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 station under Mr. L.D. Blair, with two 500-gallon underground storage tanks installed around 1959. When the tanks were removed between April 1989 and April 1991, they were found to be approximately 30 years old and in deteriorated condition — rupturing during extraction and spilling 200 to 300 gallons of gasoline. Cleanup under the Standard Cleanup program included excavation and removal of the USTs and 40 to 60 cubic yards of contaminated soil, along with collection and disposal of contaminated drill cuttings and groundwater from monitoring well development. The property is now the site of La Rosita Bakery. 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 property traces to underground storage tanks installed around 1959 and operated for roughly three decades — well within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation costs from UST removal, soil excavation, and monitoring well work were incurred to address releases that originated entirely during that pre-1986 operational window. Because cleanup has started but is not yet complete, historical carriers who issued CGL policies during the gasoline station's operating years may be obligated both to recover past remediation expenditures and to fund the work still 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.
