This property served as a JP-4 jet fuel storage facility at Boeing's North Field in Seattle, adjacent to Boeing Field (King County International Airport). JP-4 was the standard military and commercial aviation fuel from the early 1950s through the late 1970s and into the 1990s, when JP-8 replaced it — placing the fuel storage infrastructure at this site squarely within that pre-1986 operational window. Petroleum products have been confirmed in groundwater beneath the property, and the site is now under Washington's Standard Cleanup program with remediation underway. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
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 JP-4 fuel storage operations at this Boeing facility are consistent with installation and active use decades before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Confirmed petroleum contamination in groundwater — the direct legacy of those fuel storage operations — has triggered cleanup obligations under Washington's Standard Cleanup program. Historical carriers who insured the fuel storage operations during the pre-1986 window may be obligated to cover both the remediation expenditures already incurred and the costs of ongoing cleanup.
