Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1955. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

A dry cleaning facility and printer operated at this property from 1955 to 1980, leaving soil and groundwater beneath the site contaminated with perchloroethylene (PCE) and related chlorinated solvents. Remediation included the removal of two underground storage tanks and septic tanks, excavation and treatment of 180 tons of petroleum-contaminated soil, and installation of soil vapor extraction and groundwater air sparging systems, constructed covers, and a stormwater management system. Cleanup is complete, with active operations and maintenance, institutional controls, and long-term monitoring continuing under a formal O&M plan. 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 dry cleaning operations conducted between 1955 and 1980 — a 25-year period that predates the industry-wide shift away from occurrence-based Commercial General Liability coverage in 1986. CGL policies issued to the dry cleaning operator during that window had no effective pollution exclusion in Washington and remain potentially enforceable today. The documented remediation expenditures here — UST removals, soil excavation, vapor extraction, air sparging, and ongoing monitoring and maintenance obligations — are the kind of costs those historical carriers may be required to cover.

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.
