This property has a documented history as a landfill predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property, the former Seattle Steel, Inc. site on Harbor Avenue SW, encompasses a closed municipal solid waste landfill where soil and slag exceeding state cleanup standards are contained on-site under engineered covers. A Consent Decree for Cleanup Action was entered in 1995, and remediation has included landfill gas collection and treatment infrastructure — enhanced as recently as 2024 — as well as a network of monitoring wells and long-term inspections and maintenance. Groundwater use in the project area remains restricted, and the site is currently in an active operations and maintenance phase. 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 contamination here — landfill gas migration, impacted soil and slag, and managed groundwater — originated from steel mill and municipal solid waste landfill operations that, given the 1995 Consent Decree governing a facility already described as former and closed, almost certainly predate 1986 by decades. Occurrence-based Commercial General Liability policies in force during that pre-1986 operational window carried no effective pollution exclusion and remain enforceable today. The remediation expenditures documented at this site — engineered containment and capping, gas collection and treatment systems, and ongoing long-term monitoring — represent costs that historical carriers who issued policies to the operators of Seattle Steel and the landfill may be obligated to recover.
