This property has a documented history as a public works and maintenance facility going back to 1917. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
This property is part of Joint Base Lewis-McChord, a military installation with origins dating to 1917 when it was established as Camp Lewis. Cleanup at Landfill 4 has involved multi-year remediation efforts including pump-and-treat groundwater systems, in-situ sparging, soil vapor extraction, soil excavation, and low-temperature thermal desorption, with ongoing operations and maintenance documented through Five-Year Reviews. Long-term monitoring, monitored natural attenuation, cap maintenance, and Land Use Controls remain in place to prevent exposure while cleanup continues. 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.
Military operations at this installation began more than six decades before 1986, the year occurrence-based Commercial General Liability policies stopped reliably covering pollution claims. The remediation expenditures documented here — groundwater pump-and-treat, sparging, vapor extraction, soil excavation, thermal desorption, and decades of monitoring and maintenance — represent substantial cleanup costs tied to releases originating from that long operational history. Historical carriers who issued CGL policies during the pre-1986 window may be obligated both to recover past remediation costs and to fund the ongoing cleanup work still underway at this site.
