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.
Grace Dry Cleaners at 20005 Hwy 99 in Lynnwood is contaminated with tetrachloroethylene (PCE) and trichloroethene (TCE) — contaminants characteristic of dry cleaning operations — and is in active cleanup under Washington's Voluntary Cleanup Program. Remediation to date has centered on vapor intrusion mitigation: active sub-slab and sub-membrane depressurization, increased building pressurization and ventilation, sealing of potential vapor conduits, and indoor air treatment using carbon-based purification units and HVAC systems. Receptors have been temporarily relocated to reduce TCE exposure while subsurface work to permanently address soil gas sources is underway. 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-based dry cleaning at this property predates 1986, the year occurrence-based CGL policies effectively stopped providing coverage for environmental releases in Washington. The contamination documented here — PCE degrading into TCE and migrating into soil gas and indoor air — is the type of slow, ongoing release that pre-1986 policies were written to address. The active and continuing remediation expenditures at Grace Dry Cleaners represent costs that historical carriers whose policies were in force during those earlier dry cleaning operations may be obligated both to recover and to fund going forward.
