Gas Station cleanup site — Restorical Research
Wingerter Commercial Property
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 was converted from residential to commercial use in 1963, when a gasoline service station was constructed with three underground storage tanks — one 6,000-gallon and two 4,000-gallon — for automotive fuel storage, along with co-located automotive repair operations. USTs were removed in 1979, and a second round of tank removal was conducted in 2022, accompanied by excavation and offsite disposal of 228.68 tons of contaminated soil. Multi-year site characterization spanning 2021 through 2024 is ongoing, with future work planned under the Voluntary Cleanup Program including vapor mitigation, chemical treatment, and decommissioning of monitoring wells. 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 originated from underground storage tanks installed in 1963 — more than two decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion in Washington. The documented remediation trail — two rounds of UST removals, excavation of over 228 tons of impacted soil, and an active multi-year characterization program — ties directly to those historical fuel storage and dispensing operations. Historical carriers who issued CGL policies during the station's pre-1979 operational window may remain obligated both to recover costs already incurred and to fund the vapor mitigation, chemical treatment, and well decommissioning still ahead.

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.
