Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1961. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property operated as a gasoline service station from 1948 to 1960 and then housed a dry cleaning operation from approximately 1961 to 1972; three 1,600-gallon underground storage tanks and a heating oil tank associated with the earlier gas station use were removed in the early 1990s along with former building structures. Investigations confirmed tetrachloroethylene (PCE) in shallow perched groundwater at concentrations above the MTCA cleanup level, while petroleum hydrocarbons from the gas station era were not found above cleanup levels. The property is enrolled in Washington's Voluntary Cleanup Program and awaits remediation, with plans calling for excavation of 10–12 feet of soil, de-watering of perched groundwater, and potential installation of vapor barriers. 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 PCE contamination at this property originated from a dry cleaning operation that ran from 1961 to 1972 — well over a decade before 1986, when occurrence-based Commercial General Liability policies were still standard and carried no effective pollution exclusion in Washington. Chlorinated solvents like PCE migrate slowly through soil and groundwater, creating the type of continuous, long-tail release scenario that pre-1986 CGL policies were designed to cover. The anticipated remediation costs — soil excavation, groundwater de-watering, and vapor-barrier installation — are expenditures that historical carriers whose policies were in force during the 1961–1972 dry cleaning window may be obligated to fund.

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.
