This property has a documented history as a industrial and manufacturing facility going back to 1904. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as Naval Ammunition Depot Puget Sound from at least 1904 through 1959, serving as an industrial facility for the large-scale storage, handling, transfer, production, and demilitarization of ordnance — including Picric acid (Explosive D), TNT, Amatol, Composition B (TNT and RDX), Tetryl, black powder, and smokeless powder, as well as associated wastewater discharges. The site was later redeveloped as the Jackson Park Housing Complex, with residential construction beginning in 1965. Remediation is ongoing across multiple areas: 320 pieces of ordnance have been recovered, brush and surface metal removal has been completed, excavation is planned, and active work continues at the NEX Gas Station Leak and OU 3T sediment and NHB areas; investigation costs have totaled $600,000 and approximately 20 cubic yards of solid waste and 825 gallons of aqueous waste have been managed and disposed of. 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 at this property — explosive ordnance compounds, petroleum hydrocarbons from underground storage tanks, and PFAS — originates from nearly six decades of industrial ammunition-depot operations that concluded in 1959, decades before the 1986 threshold at which occurrence-based Commercial General Liability policies ceased to reliably cover pollution claims. Carriers who issued CGL policies to operators conducting ordnance production and industrial demilitarization at this facility during that pre-1986 window had no effective pollution exclusion and may remain obligated under those policies today. The $600,000 in documented investigation expenditures, combined with ongoing remediation across multiple contaminated areas, reflects a cost trail that historical carriers may be required both to recover and to fund as cleanup proceeds.
Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.
