Dry Cleaner cleanup site — Restorical Research
Westfair Cleaners
Federal Way, King County

Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1983. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Westfair Cleaners operated as a dry cleaning facility at this Federal Way property from approximately 1983 to 2001, with tetrachloroethylene (PCE) and related chlorinated solvents used in its machinery throughout that period. Sampling confirmed PCE in soil collected directly adjacent to the dry-cleaning machine and below the facility floor at concentrations exceeding Washington Ecology Method A cleanup levels. Remediation ongoing since at least 2005 has included excavation of an infiltration trench (33.33 cubic yards), injection of 7,420 gallons of potassium permanganate into soil and groundwater through the trench and two injection wells, and installation of an in-situ ozone oxidation system generating 2.7 pounds of ozone per day, with further system modifications planned as groundwater plume data continues to be collected. 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.

Dry cleaning operations at this property began in 1983 — three years before occurrence-based Commercial General Liability policies stopped reliably covering pollution claims — and the PCE, TCE, DCE, and vinyl chloride contamination documented in soil and groundwater here is the type of slow, subsurface release those pre-1986 policies were written to address. The property's development history extends further still, with structures constructed in 1965, 1975, and 1985, meaning multiple pre-1986 policy periods may be relevant to establishing carrier obligations. The documented remediation expenditures at this site — trench excavation, chemical oxidant injections, ozone system installation, and continuing plume monitoring — represent costs that historical carriers may be obligated both to recover and to fund going forward.

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.
