Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a gasoline service station since before 1986, with underground fuel storage tanks and pump islands serving retail customers. Cleanup under the Voluntary Cleanup Program has included the removal of underground fuel storage tanks, used oil tanks, and hoists, followed by multi-year groundwater monitoring and sampling from at least 1993 through 2011, with purge water treated on-site using granular activated carbon or transported off-site for disposal. The detection of lead alongside petroleum hydrocarbons in groundwater confirms that leaded gasoline was historically dispensed at this location. The station remains in active commercial use. 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 lead contamination found in groundwater at this site is a chemical fingerprint of leaded gasoline — a product phased out for on-road vehicles before 1986 — establishing that the pollution originated during the era when occurrence-based CGL policies carried no effective pollution exclusion. Nearly two decades of documented remediation expenditures — tank removals, groundwater monitoring, on-site treatment, and off-site purge-water disposal — represent costs tied directly to those pre-1986 operations. Because cleanup is ongoing, historical carriers who issued CGL policies during the leaded-gasoline era may be obligated both to recover past remediation costs and to fund the 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.
