This property has a documented history as a gasoline service station going back to 1974. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
The Ambaum Food Mart has operated as a gas station and convenience store at this location since at least 1974, when the facility building was constructed, with an 8,000-gallon and a 10,000-gallon underground storage tank supplying two gasoline dispensers under a canopy. A prior No Further Action determination was issued in 1996 for different tanks at a different location on the same property, indicating a history of UST operations extending back well before that decade. Gasoline-range petroleum hydrocarbons and BTEX contamination — attributed to a leaking underground storage tank — were identified in January 2023, and the site is currently awaiting comprehensive cleanup; initial investigation activities to date have consisted of soil borings and establishment of a drum staging area for investigation-derived waste. 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 underground storage tanks dispensing gasoline at this property have been in operation since at least 1974, more than a decade before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion in Washington. The site's layered UST history — an earlier tank system that received a 1996 NFA and the current leaking tanks — ties the contamination directly to continuous pre-1986 fuel dispensing operations. Cleanup expenditures for investigation, design, and remediation at this site could plausibly be funded by historical CGL carriers whose policies were in force during the years the contamination first originated.
