Dry Cleaner cleanup site — Restorical Research
Eastern Supply Co
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1974. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Eastern Supply Company operated as a distributor of dry-cleaning and laundry supplies in Seattle for approximately 20 years before ceasing operations in 1994. Tetrachloroethylene (PCE) — one of the products the company distributed — was released into soil from the former location of an above-ground storage tank during that operational period. Remediation included relocation of the PCE AST, excavation of 450 cubic yards of contaminated soil, pumping and aerating 4,500 gallons of contaminated groundwater, soil stockpiling and tilling, installation of a cutoff wall, groundwater sparging, vapor extraction, and asphalt pavement, with a treatment system initiated in 2001 and multi-year groundwater performance monitoring continuing through at least 2007. 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 contamination at this property originated from historical, low-volume releases that accumulated over the company's full operational life — a window beginning around 1974 that ran entirely within the era when occurrence-based Commercial General Liability policies lacked effective pollution exclusions. That pattern of gradual, ongoing release is precisely what pre-1986 CGL policies were structured to cover. The documented remediation expenditures here — AST relocation, soil and groundwater removal, a multi-year treatment system, and long-term performance monitoring — represent costs that historical carriers who insured Eastern Supply's operations during that window 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.
