Dry Cleaner cleanup site — Restorical Research

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 — and recover costs already spent.

This property was historically improved with seven structures associated with dry cleaning operations, all of which were demolished in May and June of 2008, leaving behind trichloroethene (TCE) and tetrachloroethylene (PCE) contamination — along with their degradation products dichloroethene and vinyl chloride — in the soil and groundwater. Cleanup under the Voluntary Cleanup Program has included the excavation of 9,500 tons of impacted soil and the collection and discharge of 54,000 gallons of groundwater through an active dewatering system. Quarterly groundwater monitoring is ongoing, and natural attenuation is being evaluated as a remediation strategy for residual groundwater impacts. 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.

TCE and PCE contamination of the type documented at this property is the signature of chlorinated-solvent dry cleaning operations that were widespread before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion. The seven structures that stood on this parcel were described as historical even by 2008, indicating an operational history extending well before that coverage threshold. The remediation expenditures already incurred here — 9,500 tons of soil excavation, 54,000 gallons of groundwater dewatering, and ongoing multi-year monitoring — represent costs that historical carriers may be obligated both to recover and to fund as cleanup continues.

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.
