Gas Station cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1932. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property hosted two successive gas station operations over approximately four decades, from 1932 through 1973, with underground storage tanks for gasoline and diesel installed as early as the 1930s. Cleanup under the Standard Cleanup program has included excavation and removal of two 8,000-gallon USTs and one 225-gallon waste-oil UST, removal of fuel-dispenser islands, and excavation of 64.4 tons of petroleum-impacted soil. Additional remediation work involved tank conditioning, disposal of 250 gallons of waste rinse water and 150 gallons of oil and sludge, and site restoration including backfilling and pipe repair. Cleanup work 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.

Petroleum contamination at this property traces directly to gas station operations that began in 1932 — more than five decades before the 1986 cutoff after which occurrence-based Commercial General Liability policies ceased reliably covering pollution claims in Washington. The documented remediation expenditures — UST removals, soil excavation, waste disposal, and site restoration — were incurred to address releases from those pre-1986 operations. Historical carriers who issued CGL policies to the operators during the 1932–1973 service-station era may be obligated both to recover costs already spent and to fund the cleanup work that remains.

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.
