Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1928. 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 Shell Oil Company branded gasoline service station from 1928 through approximately 1972, with two 5,000-gallon and one 8,000-gallon underground storage tanks, two pump islands, and two car hoists on site — tanks installed in 1959 and 1970. Contaminants consistent with decades of fuel dispensing operations, including gasoline, diesel, and BTEX compounds, have been identified at the property. The former service station structure has since been demolished, investigative waste has been containerized in a 55-gallon drum, and the site is currently awaiting further cleanup actions. 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.

Fuel storage and dispensing at this address began in 1928 and continued for more than four decades before 1986, the period when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion. Underground storage tanks were installed — and releases plausibly began — in 1959 and again in 1970, implicating multiple pre-1986 policy periods across Shell's branded operation of the site. The investigative costs already incurred and the remediation work still pending represent expenditures that historical carriers who issued CGL policies during those operational decades 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.
