Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1969. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as an active dry cleaning facility since 1969, with perchloroethylene (PCE) used in its cleaning machinery throughout that period. Groundwater contamination — PCE at concentrations up to 1,300 µg/L along with its breakdown products trichloroethylene (TCE), cis-1,2-dichloroethylene, and vinyl chloride — has been confirmed through direct-push site investigation. The site entered the Voluntary Cleanup Program but that agreement was later terminated due to a lack of active cleanup progress; no excavation, groundwater treatment, or soil vapor extraction system has been implemented to date. 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.

PCE releases at this property trace to dry cleaning operations that began seventeen years before 1986, when occurrence-based Commercial General Liability policies were still the industry norm and carried no effective pollution exclusion. The presence of TCE, cis-1,2-DCE, and vinyl chloride — classic reductive dechlorination products — confirms a historical release rather than a recent event, directly implicating the policy years when contamination first occurred. With the VCP agreement terminated and no substantive remediation yet accomplished, the full cost of investigation design, source control, and groundwater cleanup remains ahead — expenditures that historical carriers whose policies were in force during those pre-1986 operating years 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.
