This property has a documented history as a gasoline service station going back to 1966. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
An auto station has been documented at this Seattle address since at least 1966, with two 2,000-gallon gasoline underground storage tanks installed around 1970 and a fuel release reported around 1972; those tanks were formally abandoned in 1985. Investigation and early remediation have included recovery of 129 gallons of light non-aqueous phase liquid (LNAPL) through skimmer pumps, vacuum extraction, and submersible pumps, along with in-situ groundwater treatment using oxygen release compounds and sorbent socks, supported by multi-year monitoring from 2011 through at least 2024. Lead — a marker of leaded gasoline dispensed more than forty years ago — remains detectable in current groundwater samples, and no active cleanup work has yet commenced. 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 gasoline operations running from at least 1966, with a documented release reported around 1972 from tanks that remained in service through 1985 — a span falling entirely within the era of occurrence-based Commercial General Liability policies. Lead still detected in 2024 groundwater samples is a direct chemical signature of fuel dispensed at this location before leaded gasoline was phased out, confirming a contamination origin that is demonstrably pre-1986 rather than attributable to any recent incident. The cleanup costs now ahead — continued LNAPL recovery, in-situ treatment, and long-term monitoring of a multi-parcel plume — represent expenditures that historical carriers whose policies covered the 1972 release and surrounding operational years may be obligated to fund.
