Gas Station cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1930. 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 station from approximately the 1930s through 1966, known successively as C.B. Folk's Shell and Cramer's Shell Service. Cleanup under the Voluntary Cleanup Program has included the excavation and removal of five underground storage tanks and 1,300 cubic yards (1,975 tons) of contaminated soil, with off-site disposal. A groundwater monitoring program was established in 1995 with three monitoring wells and sampling events conducted through 2001, with natural attenuation contributing to groundwater quality improvement. The property has since been used as automobile parking space. 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.

Gasoline dispensing operations at this site began in the 1930s — more than five decades before 1986, when occurrence-based Commercial General Liability policies ceased reliably covering pollution claims in Washington. The contamination discovered here, including lead-bearing gasoline consistent with pre-1986 fuel formulations, originated squarely within the coverage window of those historical policies. Documented remediation expenditures — tank removal, large-scale soil excavation, and years of groundwater monitoring — represent costs that historical carriers who wrote CGL policies during the station's operating life may be obligated both to recover and to fund going forward.

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.
