This property has a documented history as a gasoline service station going back to 1917. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
The 4th Avenue strip at the Fremont Bridge Approach is adjacent to a former service station that operated from approximately 1917 until at least 1950, releasing gasoline-range petroleum hydrocarbons and BTEX compounds that migrated into both soil and groundwater. Petroleum contamination was first detected at the site in 1995, with TPH-G and BTEX concentrations confirmed to exceed MTCA cleanup levels. Planned remediation calls for special handling and disposal of contaminated soil removed during excavations, and treatment of extracted groundwater with granulated activated carbon or off-site disposal during dewatering. 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 traces to a service station that ran for more than three decades — from approximately 1917 to at least 1950 — entirely within the era when occurrence-based CGL policies were the industry standard in Washington. The TPH-G and BTEX releases that now exceed MTCA cleanup levels in soil and groundwater originated from operations that predated 1986 by at least 36 years. Excavation, contaminated-soil disposal, dewatering, and activated-carbon treatment costs the property owner will incur going forward are precisely the type of cleanup expenditures that historical carriers who issued policies during that long operational window may still be obligated to fund.
