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.
The SW 156th Street PCE site in Burien centers on tetrachloroethylene (PCE) contamination associated with the former Norge Cleaners dry cleaning operation and an active dry cleaning tenant space identified as Five Corners Cleaners at the same address. Ecology opened the investigation following a confidential complaint about dry cleaning solvents in groundwater; sampling confirmed PCE in soil above the MTCA Method A Soil Cleanup Level and groundwater concentrations reaching 13,000 parts per billion inside the dry cleaning tenant space. Remediation work has been conducted at the adjacent 2 Roy Street property — including soil removal, sump excavation, former-UST excavation, and vadose-zone soil treatment — while the primary site remains listed as Awaiting Cleanup pending a future remediation 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.
City directory records cited in a 2004 investigation report document dry cleaning and laundry operations at this location prior to 1986, placing the origin of the PCE plume squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The contamination here — high-concentration PCE in both soil and groundwater beneath the dry cleaning tenant space — is consistent with slow operational releases accumulated over years of solvent use, precisely the type of ongoing pollution event those pre-1986 policies were written to address. As the primary site moves into an active remediation program, historical carriers whose CGL policies were in force during the Norge Cleaners operational period may be obligated to fund the investigation and cleanup costs the property now faces.
