Gas Station cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1979. 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 before its conversion to a bank, with at least two underground storage tanks identified on-site through ground-penetrating radar. A Phase II Environmental Site Assessment in October 2004 confirmed petroleum hydrocarbon impacts to both soil and groundwater; cleanup activities included the removal of one gas UST and the excavation and off-site disposal of approximately 377 tons of contaminated soil. Additional USTs may remain beneath the parking lot, and remediation work is ongoing under Ecology's Standard Cleanup program. 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 traces to underground storage tanks estimated to have been installed around 1979 — well within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The cleanup costs already incurred — tank removal, large-scale soil excavation, environmental assessment — and the costs still ahead as the site works toward closure represent expenditures that historical CGL carriers 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.

What We Look For

  • Historical insurance policies (pre-1986)

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.
