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 at 1314 E Pike Street in Seattle operated as a dry cleaning facility, with tetrachloroethylene (PCE) and related halogenated volatile organic compounds confirmed in soil and groundwater as a direct result of those former operations. Cleanup efforts began in 2008 with a remedial excavation reaching depths of up to 20 feet, followed by a soil vapor extraction system that operated from 2009 through 2020 and removed approximately 29 pounds of PCE. Active in-situ treatment has included chemical oxidation, chemical reduction using S-MicroZVI® and sodium permanganate injections, and biologically-mediated reductive dechlorination, with monitored natural attenuation and multi-year monitoring continuing alongside a disproportionate cost analysis. 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 that predated 1986, the era when occurrence-based Commercial General Liability policies were standard and had no effective pollution exclusion in Washington. Documented remediation expenditures — a 20-foot excavation, over a decade of soil vapor extraction, repeated in-situ chemical injection programs, and ongoing monitoring — represent costs tied directly to that pre-1986 operational history. Historical CGL carriers whose policies were in force during those dry cleaning years may be obligated both to recover costs already incurred and to fund the treatment program that remains active today.

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.
