This property has a documented history as a dry cleaning facility going back to 1963. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
This property housed Callow Cleaners, a dry cleaning operation documented at 324 Callow Avenue North from at least 1963 through approximately 1978. A Phase II Environmental Site Assessment has confirmed contamination in soil, groundwater, and soil gas attributable to dry cleaning solvents used during those operations; the site is currently classified as Awaiting Cleanup, with no remediation activities initiated or completed to date. The building itself dates to 1939, predating the dry cleaning tenancy by more than two decades. 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 tetrachloroethylene and carbon tetrachloride contamination at this property traces directly to dry cleaning operations that ran for roughly fifteen years before the mid-1970s — well within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Because no cleanup has yet begun, the full cost of investigation, remediation design, and active cleanup remains ahead; historical carriers whose policies were in force during Callow Cleaners' operational years may be obligated to fund those upcoming expenditures.
