Preliminary Site-Specific Analysis

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

This site is linked to the former National Cleaners dry cleaning operation, which contaminated soil and groundwater with tetrachloroethylene (PCE) and its breakdown products — trichloroethylene (TCE) and vinyl chloride — at concentrations exceeding Washington's MTCA Method A cleanup levels. PCE has migrated downgradient from the former dry cleaner's location, establishing an active plume. The only cleanup activity completed to date is disposal of investigatively-derived waste drums from initial sampling; the main site remains enrolled in the Voluntary Cleanup Program and awaiting active remediation. 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.

National Cleaners' PCE release — confirmed by a downgradient plume already exceeding MTCA Method A standards — originated from a historical dry cleaning operation conducted well before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The presence of TCE and vinyl chloride alongside the parent PCE compound indicates a long-standing, ongoing release pattern of precisely the type those pre-1986 policies were written to cover. With site investigation just beginning and active remediation not yet underway, the cleanup costs ahead — groundwater treatment, soil remediation, long-term monitoring — are expenditures that historical carriers whose policies were in force during National Cleaners' 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.
