Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1950. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property operated as a gasoline station and grocery store beginning in 1950, with underground storage tanks holding heating oil and other petroleum products on-site for decades. In 2008, two USTs — a 1,100-gallon heating oil tank and a 100-gallon tank of unknown contents — were excavated and removed, along with approximately 148 tons of petroleum-impacted soil. The site remains enrolled in the Standard Cleanup program with active remediation yet to commence. 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 — gasoline-range hydrocarbons, ethylbenzene, and xylenes — originated from underground storage tanks installed and operated from 1950, more than three decades before the 1986 threshold at which occurrence-based Commercial General Liability policies ceased reliably covering pollution claims. The 2008 tank removals addressed the contamination source, but site remediation has not yet begun. The investigation, design, and cleanup costs the property owner now faces could plausibly be funded by historical carriers whose CGL policies were in force during those pre-1986 operating years.

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.
