Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1974. 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 from 1974 through 1994, with three underground storage tanks — two 550-gallon and one 2,000-gallon — along with five hoists and three pump islands dispensing fuel on site. In June and July 2021, subsurface chemical injections (PersulfOx) were performed to reduce groundwater contamination, followed by quarterly monitoring events from Third Quarter 2021 through Third Quarter 2022 to evaluate remediation progress. Cleanup work remains 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.

The petroleum contamination at this property — gasoline-range TPH and BTEX compounds released from underground storage tanks — originated from fueling operations that began in 1974, more than a decade before occurrence-based CGL policies ceased to carry meaningful pollution coverage. Carriers who issued policies to the service station operators during the 1974–1986 window wrote coverage without an effective pollution exclusion under Washington law. The documented remediation expenditures — chemical injection treatment and years of groundwater monitoring — represent costs those 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.
