Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1938. 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 retail gasoline and automobile service station from approximately 1938 to 1977, with at least seven underground storage tanks, two fuel pumps, and two hydraulic lift hoists present on site during that period; the station closed in 1981. Cleanup under the Voluntary Cleanup Program has included the excavation and disposal of 2,897.81 tons of petroleum-contaminated soil, multi-year quarterly groundwater monitoring from May 2012 through January 2013, abandonment of old monitoring wells, installation of new monitoring wells, and management of purge water. The property is currently vacant. 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 documented at this site traces directly to nearly four decades of underground storage tank operations that concluded before 1977 — well before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion in Washington. The scope of documented remediation here — close to 2,900 tons of excavated soil and years of groundwater monitoring — reflects the cleanup burden left by those pre-1986 operations. Historical carriers who issued CGL policies to the operators during the station's 1938–1977 run may still be obligated to fund ongoing cleanup costs and to recover expenditures already incurred.

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.
