This property has a documented history as a dry cleaning facility going back to 1937. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property has been in continuous commercial use since 1937, operating as a gasoline and service station with underground storage tanks from 1940 to 1955 and then as the Kwik Cleaners dry cleaning facility from 1955 through 1999. The primary contamination consists of tetrachloroethene (PCE) and its chlorinated breakdown products — trichloroethene (TCE), dichloroethene isomers, and vinyl chloride — released through a floor sump and oil/water separator during dry cleaning operations, with dense non-aqueous phase liquid (DNAPL) present in the subsurface. Remediation to date has included historical tank removal, and investigation continues under the Voluntary Cleanup Program, which is evaluating targeted soil excavation (a 30-by-30-foot area to 15–20 feet in depth), ozone-enhanced air sparging combined with soil vapor extraction, long-term DNAPL containment and pumping, in situ chemical oxidation, and enhanced bioremediation, among other alternatives. 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 chlorinated solvent contamination at this property originated from dry cleaning operations that ran for more than three decades before 1986, the year occurrence-based Commercial General Liability policies ceased to offer meaningful pollution coverage in Washington. The 1940–1955 gasoline station adds a second pre-1986 contamination source, with USTs in service during the era of leaded-fuel dispensing and no effective pollution exclusions. The site's documented and anticipated remediation expenditures — tank removals, soil excavation, DNAPL recovery, vapor extraction, and multi-year monitoring — represent costs that historical CGL carriers who issued policies during either the gas station or dry cleaning eras may be obligated both to reimburse 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.
