This property has a documented history as a industrial and manufacturing facility going back to 1890. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
Terminal 115 Plant 1 occupies a shoreline position on the Lower Duwamish Waterway, an active industrial corridor in Seattle with documented commercial and industrial activity dating from the late 1800s — including sawmills, shingle mills, and shipbuilding and repair operations. Cleanup at the site is ongoing and encompasses navigation channel maintenance dredging, completed ecological restoration projects, identification of Early Action Areas, and a multi-year source control strategy with action plans issued or in development across numerous areas. Associated groundwater sites are under active monitoring as part of the broader 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.
Contamination at this property traces to industrial operations that began more than a century before 1986, when occurrence-based Commercial General Liability policies were the prevailing standard and lacked effective pollution exclusions. PCBs — banned in 1979 — identified at the site confirm that contamination originated from historical industrial sources operating squarely within that pre-1986 policy window. The remediation program here — dredging, ecological restoration, source control across multiple action areas, and long-term groundwater monitoring — represents cumulative expenditures that historical carriers whose policies were in force during those decades of industrial activity may be obligated both to recover and to fund as cleanup continues.
