Gas Station cleanup site — Restorical Research
Spring Air Northwest
Tacoma, Pierce County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1963. 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 with multiple underground storage tanks, confirmed by aerial photography as early as 1963. Cleanup under the Voluntary Cleanup Program has included removal of three USTs totaling 3,550 gallons, closure in place of a 7,000-gallon tank, excavation and offsite disposal of 2,804 tons of contaminated soil, and operation of a pump-and-treat system that recovered 100 gallons of free petroleum product over two years. Groundwater monitoring has been conducted over several years, and the former fueling station is no longer in operation. 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 site — including lead detected in groundwater, a signature of leaded gasoline that ceased production before 1986 — traces directly to fueling operations that were in place decades before the pollution exclusion transformed Commercial General Liability policies. The scale of documented remediation expenditures, from thousands of tons of soil removal to years of groundwater treatment and monitoring, represents costs that historical carriers who issued occurrence-based CGL policies during the station's active years may be obligated to reimburse and to continue funding as cleanup work proceeds.

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.
