This property has a documented history as a industrial and manufacturing facility going back to 1936. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The property at 747 S Monroe Street served residential use from 1936 through the early 1990s, during which period polychlorinated biphenyls (PCBs) accumulated on site. In 1991, Independent Metals Corporation began operating a scrap metal recycling business, accepting, sorting, and preparing non-ferrous metals such as copper, brass, and aluminum for recycling. Cleanup activities under the Voluntary Cleanup Program have included prompt cleanup of spills, waste recycling and disposal, upgrades to the stormwater collection and treatment system, and regular drainage and catch basin maintenance. The facility has also been identified as a Potentially Responsible Party for the Lower Duwamish Waterway Superfund Site. 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.
PCB contamination at this property is attributed to legacy accumulation during the residential period that began in 1936, placing the origin of contamination decades before 1986. The property's designation as a Potentially Responsible Party for the Lower Duwamish Waterway Superfund Site compounds the cost exposure beyond the site's own ongoing cleanup obligations under the Voluntary Cleanup Program. Historical carriers whose CGL policies were in effect during the years PCBs were accumulating at this location may bear responsibility for both past remediation expenditures and the Superfund-related liabilities still ahead.
