Dry Cleaner cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1926. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property carried a succession of commercial operations stretching back to 1926: a gasoline service station from 1926 through 1954, then Nutone Dry Cleaners from 1954 to 1959 and Vern's Dry Cleaners from 1962 to 1967, followed by a return to service-station use from 1970 to 1990. The dominant environmental concern is chlorinated volatile organic compound (CVOC) contamination — PCE and TCE — traced directly to those dry cleaning operations, with petroleum hydrocarbon concentrations from the service-station USTs now at or below cleanup levels. Remediation from 1991 to 1994 included removal of underground storage tanks, hydraulic hoists, a sump, and a concrete septic tank, along with excavation of approximately 460 cubic yards of impacted soil and disposal of over 2,500 gallons of contaminated liquids and sludge. Groundwater monitoring is ongoing and soil vapor sampling was planned, indicating that delineation of the CVOC plume remains an active effort. 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 CVOC contamination driving cleanup at this site originated from dry cleaning operations that ran from 1954 through 1967, and the service-station USTs in operation from the 1920s onward also predate 1986 by decades — the period when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Carriers who issued CGL coverage to operators during those pre-1986 windows wrote policies designed to cover exactly this kind of slow, subsurface release, whether from solvent-based dry cleaning machinery or leaking underground tanks. The documented remediation expenditures here — tank and equipment removals, soil excavation, waste disposal, and multi-year groundwater and vapor monitoring — represent costs that historical carriers 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.
