Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1976. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This strip mall property was developed in 1976 and 1977, and a former dry cleaning operation on site used tetrachloroethylene (PCE) as its primary solvent, releasing PCE and its degradation products — trichloroethylene (TCE), cis-1,2-dichloroethylene (DCE), and vinyl chloride (VC) — into underlying soil and groundwater. Remediation to date has included excavation of PCE-contaminated soil to a depth of 16.7 feet and management of 21 55-gallon drums of investigation-derived waste, with a cost estimate technical memorandum already prepared. Natural attenuation of residual groundwater impacts is anticipated over the next two years, long-term groundwater monitoring is planned, and the site is expected to enroll in a Voluntary Cleanup Program. 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 dry cleaning operations that caused this contamination were conducted in a facility built in 1976 — a full decade before occurrence-based Commercial General Liability policies began incorporating effective pollution exclusions. PCE and its chlorinated breakdown products are characteristic of the slow, ongoing subsurface releases that pre-1986 CGL policies were designed to cover. The excavation costs, waste disposal, and the groundwater monitoring program now being structured represent exactly the remediation expenditures that historical carriers whose policies were in force during those dry cleaning operations 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.
